Urban Planning and Design for Cities: Skylines alborzka August 16, 2017 Abstract This document aims to serve as a comprehensive. simple guide for Cities: Skylines (C:S) players who want to incorporate elements of professional, real-world urban planning and city design into their cities. All information here is taken from online academic courses on urban planning, using the latest trends and knowledge. City planning is much more complicated than can be experienced in C:S, and urban planning can’t be summed up in a few pages. It involves several disciplines and experts specialised in particular areas, and real cities aren’t designed by one “Jack of all trades”. Thus, this document seeks to enable readers to learn as many aspects of city design as can be possibly implemented in-game. Aspects such as economic policy and other areas not touched upon in C:S are similarly not touched upon in this guide.

Going through the document, you’ll get the hang of how this is organised and how to use it, but just a quick tip: If you’re looking just for instructions and guidelines to follow when making cities, and don’t really care about the theory, just read the Appendix in order as well as the Airport–City Connection section and Building Design Principles section. If you’re interested in the theory, and want to know why you should build in this way, read the sections that interest you and refer to the appendices for instructions and more detail. The next two paragraphs are some introductory remarks that I didn’t know where else to put. The primary infrastructure of a city is comprised of transport, energy, water/sewage, waste, housing, communications, green infrastructures. Secondary infrastructures include health care, education, nutrition, culture, and others; these are secondary because they function only if primary infrastructures function. We evaluate primary infrastructure using three (3) main objectives or performance indicators: sustainable, efficient, resilient. An urban system wants to pursue quality of life, city attractiveness, and city competitiveness. Social dimensions of infrastructure can promote equity exclusion (highway dividing the city) and equity inclusion (highway bringing people to work). Infrastructures can go either way or both! The territorial space-frame of a city or region is built on three (3) things whose arrangements have changed since the 1960s: Morphology, Functional Centralities, and Lifestyles. Until the 1960s, these three things overlapped by snapping-in. For example, urban areas and their surroundings were regionalised, and distinctions were drawn between country and city. Looking at a small village, you could tell people 11 lived most of their lives in it and their lifestyle revolved around it. Now, thanks to rapid transit systems, the possibilities of location are expanding. Morphological boundaries fade (urban sprawl) — it’s now difficult to tell where a city begins and ends, both visually and funcionally. Lifestyles change and detach themselves from spatial proximity; ones daily life is now within a large geographic range. However, this expansion doesn’t kill spatial differentiations! Not everything becomes urban! Mobility becomes the link connecting Morphology, Function, and Lifetsyle. People can work and shop tens of kilometres1 away from where they live, including in large metropolitan (international) centres like Geneva. 1 City Design History 1.1 Pre-Industrial Revolution There were five (5) main characteristics of cities prior to the Industrial Revolution across the world. Not all historic cities have all of these characteristics, but they will more than likely have one or more of them. 1.1.1 The Wall Defence was essential for millennia. Even after walls came down and the moats were drained, the idea of creating limits to the city remained. This was especially true for European cities where walls created “membership”into the city, and those outside the city (not just outside the country) were considered foreigners. 1.1.2 The Grid Contrary to the common belief that grid systems are mainly an American phenomenon, the first grid system was created by the Greeks around 300 BC. As land ownership was dispersed to families and people, the need to subdivide property in some logical way and record it onto maps became apparent. There was also a need to define public areas like streets and squares. 1.1.3 The Axis Some parts of the city (and some people) were more important than others throughout history. Even in a grid city like Beijing, the importance of the Emperor was reinforced by creating a central axis that only he was allowed to use. In Renaissance Rome, Pope Sixtus the 5th used axes as way of uniting separate districts of city and creating important plazas and buildings. 1.1.4 The City Square In European cities, squares were created to become the living room of city, a place for all important events. Squares often started as open market places, and as markets moved indoors, they became spaces for multiple purposes. In Northern Europe, squares can also function as green spaces, offering relief from the dense city; this idea was carried over into the New World. 1 Or miles, if you’re stuck in the 1800s. 12 1.1.5 The Cloister A cloister is a space created for monasteries, places of worship, temples, and/or shrines. These places were often given prominent locations in the city. Bangkok’s wats define that city, and churches often mark the centre of neighbourhoods and districts of Western cities. These places were then accompanied by schools, meeting houses, and residences. 1.2 Cities in the Industrial Revolution Canals were used as a primary means of transporting goods before trains were introduced. The creation of train tracks widened the trading scope of cities and intensified development in their city centres. During this time, workers lived right next to, and sometimes within, industrial areas and factories. This created unhealthy living conditions. With the introduction of the car, buses, and trains, city roads became crowded and polluted. 1.3 Cities in the 1950s The cities of the 1950s, when people went to a single urban centre to work, shop, play, etc., are still what many people think cities are or should be. Such cities were defined by the prominence of their Central Business District (CBD), which functions as the city’s dominant commercial centre. This serves as the location of central railway station(s), government, most office buildings, and the best retail, hotels, theatres, and restaurants. Close-by were some of the most expensive residential districts fronting on landscaped parklands. This central city was surrounded by industry, except for fashionable streets leading to the best suburbs. The working class lived near the industrial areas, close to the factories in which they worked. Middle class suburbanites were connected to the CBD by tram or commuter rail. This mid-century city was created by attempting to correct the mistakes made when cities first became industrialised. The Transect Diagram shown in Figure 1 is used by advocates of New Urbanism as a template for writing zone and design guidelines. It captures the organisation of a city as it was in 1950. Certain areas that don’t fit the diagram, e.g. stockyards, are labelled as “special districts”. The problem with this diagram, however, is that cities are no longer the way they were in 1950. These neighbourhood designs were built on a foundation of discrimination and deed restrictions, as most people still lived in cramped slums. 1.4 Today’s Regional City Starting in the 1950s2 , most people had personal cars, so cities began to be divided into a pre-1950’s “old city” and a suburban “new city” which was ideal for cars. The old downtown was at the periphery of the much more affluent new city. Buildings were emptying out and their businesses were moving to the new city centre as well. The new city developed office and retail centres of its own, but were much more 2 This entire sub-section is US-centric. Most other developed countries had their old city centres remain dominant, but still experienced suburbanisation enabled by cars. 13 Figure 1: Transect Diagram, showing city design of the 1950’s. spread out compared to the old city. Afterwards, the suburbs kept spreading to the point where it became dysfunctional for residents — people complained about traffic congestion, long commutes to work, segregation of functional areas made mothers work as chauffeurs for their children, shopping required driving from one destination to another, etc. So, the old 1950’s model with a CBD and walkable neighbourhoods seemed good in comparison. In the past few decades, the US has seen a big downtown revival and rise in real estate values for walkable neighbourhoods and suburbs. 2 Different Design Schools The four (4) designs discussed here aren’t opposed to each other and aren’t mutually exclusive. Rather, some are applicable to some times and circumstances while others remain inapplicable. The idea is to pick (and maybe blend) what designs work right for particular projects. 2.1 Modernist City Design The modernist school of city design features elevated highways running right through cities and clearing land around them for high-rise office towers. This has the side-effect of dividing one community into two, one on each side of the highway. Rivers and highways divide city up into separate neat districts. Whole sections of towers appear in rows or clusters. The taller buildings are, the further apart they can be placed and still accommodate the same amount of space. With the right orientation, buildings can be spaced so that sunlight falls on the full façade of the neighbouring building, as shown in Figure 2. Such designs are actually implemented as law, known as “Sunshine Laws” in countries such as Japan. One feature of modernist design is that of Significant Form: buildings stand out from their neighbours. One can make any shape buildable, such as a piece of crumpled paper. 14 Figure 2: Better building and tower spacing. 2.2 Traditional City Design In traditionalist city design, radial avenues from squares extend in all directions. Long straight streets connect important destinations. Important landmarks could be placed between the beginning/ends of two radial streets converging. Important destinations, landmarks, and places within squares would have important roads extending from them in all directions, connecting them straight to other important squares. The spaces formed between these important avenues would then be filled with smaller streets (grid or otherwise) and less important buildings. The road layouts of Washington D.C. and Paris are good examples of traditionalist city design. For smaller cities or towns, squares could be surrounded by individual houses that all look alike. Individual houses can be used to form other grand architectural compositions, such as circles/plazas with avenues leading to them. Note that one may use traditional city design to connect important landmarks/places with roads that aren’t necessarily straight. New Urbanism uses such a method, where roads are sometimes curved along the coast (and with adjacent important roads following that curve) as shown in Figure 3. You don’t need to use classical buildings to use traditional city design planning! 2.3 Green City Design Green city design, also called Landscape Urbanism, integrates natural landscapes into the designs for cities. It focuses on adaptation; learning new ways to reorganise the natural environment. This is important for all cities dealing with climate change (aka, all cities); for example, rising sea levels will change the way harbour cities function and look. Barriers with locks (holes that allow ships to pass through) can be used for coastal and riverside cities to protect them from rising sea levels. One may correct mistakes introduced by industrial cities and by misguided use of elevated highways and railways, e.g. by converting them into streams and landscape or elevated parks. Highways next to rivers 15 Figure 3: Traditionalist city design in New Urbanism. could be lowered with the top being landscaped, as another example. Garden cities3 help make shops and amenities walkable, with big houses further away but the majority of the city walkable and green. 2.4 Systems City Design A systems city design focuses on structural systems, such as walls, beams, etc. This is a new and more futuristic design school. Structural system cities could be built with interconnecting escalators, pillars, glass, and other components (basically like lego, made of components that are all of the same size stacked and arranged together to build a structure). 3 3.1 Environmental Considerations Ecological Urbanism Landscape Urbanism, also known Ecological urbanism, emerged in the 1990s as a response to postmodernist architecture which was retreating back to European models, as well as disasters of industrial cities, to make them better community-wise. Ecological urbanism aims to synthesise cities and nature, i.e. synthesise the synthetic and physical interface between buildings, infrastructure, natural ecology, and culture. It seeks to “activate space and produce urban effects without the weighty apparatus of traditional space making”. 3 There wasn’t much else discussed on garden cities in the courses I took, so use Google to figure out its pros and cons. Generally, from my knowledge, not a great idea unless you incorporate bits and pieces of it here and there. 16 3.2 Managing Water: Flooding and Scarcity The concept of Design With Nature, developed by Ian McHarg, focuses on preserving the natural environment as much as possible, as it performs important functions for us. Such functions can include acting as flood barriers, dispersal of air pollutants, and purifying and storing water, among others. The following areas are listed in order of environmental importance according to this theory, i.e. from least to most suitable for urban development: surface water, flood plains, marshes, aquifer recharge areas, aquifers, steep slopes, forests/woodlands, and unforested lands. Many cities use concrete structures to act as barriers to flooding. Sand dunes (with hardy grasses), however, are more sustainable flood barriers than concrete as concrete erodes over time while sand absorbs waves. Sand dunes are good for protection from the ocean in coastal areas such as the Netherlands. For delta regions, however, sand isn’t enough and you’ll need constructed (e.g. concrete) barriers. Marine barrages such as those seen in Singapore4 can keep sea water out and act as a fresh-water reservoir, while also acting as attraction with recreational parks as well as districts in new bays. Adding barriers may not be the only solution to address rising sea levels. Very low-lying and low-density areas prone to flooding can be relocated onto the water by using floating buildings, for example. The modern neighbourhood of Ijburg, Netherlands, has this set-up with docks acting as sidewalks. Building on the water with floating buildings makes a lot of sense since it frees up valuable land for food production, while some waste can be used5 to feed fish and algae. Water scarcity is a significant issue already and will only continue to grow in severity. Wetlands can be constructed to clean polluted water for non-potable purposes like urban agriculture. These wetlands can also be made into attractive parks by adding boardwalks along it, thus serving two functions at once! Wetlands also help prevent flooding naturally; not as effective as barriers in very low-lying areas, but still helpful in many other places. 3.3 Managing Energy Consumption In 2007, the US breakdown for energy consumption was transport at 29 %, industrial at 39 %, residential at 21 %, and commercial at 18 %. Energy consumption can be managed by 1. Reducing demand, e.g. reducing travel by implementing energy-efficient urban forms, providing efficient modes of transport, and locally sourcing things. 2. Improving energy supply, e.g. by adding renewables, reusing waste heat, providing local heating/cooling (such as household geothermal pumps), and developing other new systems to control and optimise energy. Green city planning makes people act sustainably without thinking about the environment. For example, Copenhagen has most of its residents biking for convenience and health, as opposed to environmental 4 5 Not really a delta region, I know, but not sure where else to put this. Not how it works in C:S though, unfortunately! 17 reasons. Making biking as convenient as possible and giving it priority in planning is what makes this possible. Infrastructure to achieve this may include multiple bike lanes for different speeds, easy stopping bars and ground lights at intersections, dedicated (not shared) lanes, and direct routes by bike lanes that aren’t available to cars. Part of green city planning is making complete streets, which “do all” by serving as many modes of transport as possible. This is done by having space for pedestrians, bikes, public transit, and motorists. This encourages people to walk or bike since they have the space to do so. Complete streets are discussed in-depth in Appendix B. In some European cities, they make sure transit lines are constructed before further urban development, so that people don’t get into the habit of driving in the first place. A great place to start creating transit-oriented communities is Appendix A. In general, the more dense a city is, the less energy is consumed per capita, as most facilities are a walk away and transit is close. However, simply increasing density by itself doesn’t improve environmental health, as smog-ridden cities such as Beijing show. 3.4 Green Infrastructure and Urban Agriculture Urban areas tend to be 5 ∘C warmer than surrounding areas. This is known as the urban heat island effect. Mitigating heat island effects is important as it reduces the amount of energy spent on cooling (e.g. air conditioning). One easy way to incorporate green infrastructure is by adding trees on roads and elsewhere, as they help mitigate urban heat island effects by providing shade. Heat island effects can also be mitigated by changing the colour and reflectivity of a parking lot, e.g. painting it green, which can lower its temperatures under the hot sun. In addition, placing solar panels over water filtration plants provides a cooling effect, which in turn increases the efficiency of solar panel output. Finally, Singapore’s SuperTrees consist of vertical gardens that provide shade to the ground below, while generating solar power. Green roofs are an excellent form of green infrastructure since they absorb grey water, reduce pressure on sewage, keep buildings cool in the summer by reducing energy consumption by 10 %, mitigate urban heat island effects due to their green colour, increase biodiversity within the area, and actually increase the lifespan of roofs by protecting roof membranes from UV rays and temperature fluctuations. They are also great for serving as local parks or areas for residents to relax, significantly increasing the land available for the city while greatly improving quality of life. In addition to being pretty, such green spaces help address stress and improve cognitive and mental health. Environmental literacy involves teaching children and youth environmental values to promote a resilient city. Contact with nature, the ravine systems, and food gardens provides physical and emotional benefits. Studies show that nature-play leads to developing a stronger immune systems in children. When children develop an understanding and appreciation of ecological processes they become citizens who make more sustainable choices. Provide learning opportunities for children through elements such as visible stormwater management, using spillways that flow into landscape beds. Explore opportunities to develop community gardens in open space or food gardens on rooftop amenity space. 18 Urban agriculture is now being recognised for its ability to help improve the self-sustainability of a city, especially important given growing uncertainties over reliable food supplies. It also mitigates greenhouse gases by reducing “food miles”, which is the travel needed for food to get to stores. Concerns such as city land being too valuable for farming are mostly unwarranted, as even areas with limited space such as Singapore are building full scale urban farms (including vertical farms, which are great for areas with limited space).6 An example of this is Sky Greens in Singapore, a vertical greenhouse farm which grows 80 tons of vegetables annually. Areas with urban agriculture can also serve as tourist attractions. For example, an “agrofood tourism” trail can take visitors through farms and shops, acting as a local attraction while serving agricultural functions. 4 4.1 Preserving Older Cities and Districts Importance of Historic Preservation Preserving existing infrastructure, buildings, and old cities in general is usually better than starting from scratch. Every brick has energy used to go into its creation, and entropy7 renders energy less useful each time it’s transformed. Once that brick is destroyed, that useful energy is gone and you have to spend energy to make a new brick. Thus, preserving bricks (or any other material) and the things made up of these materials, is much more energy efficient and better for the environment. Furthermore, people grow attached to their local streets and historic buildings, and old districts create a sense of community and sense of place that can easily be destroyed by demolishing it. Classifying an area as a historical district doesn’t mean preserve everything the way it is! These arguments have often been used by wealthy people to keep “the poors” out of their neighbourhoods when space is becoming a premium. Urban renewal and change is unavoidable, but the way old buildings are repurposed, and the areas in which new buildings blend in with older ones, are what is important. The character of the neighbourhood should be preserved, and this can be accomplished without turning the area into a museum. 4.2 Adaptive Re-Use of Old Buildings Adaptive re-use of buildings helps preserve identity and a sense of place, while making use of the embodied energy of that building. When publicly accessible, adaptive reuse of historical buildings can benefit the community. Old churches for example can be converted into lofts, book stores, or even nightclubs. However, residential areas shouldn’t be destroyed/gentrified to make a Disney-land, touristy, fictional historic space that ruins its true character. This has happened in many working class neighbourhoods, and it destroys the authentic character that made that location popular in the first place. A practice met with disdain by many preservationists (and those with good taste), facadism involves keeping the front (just the façade) of a historical building while demolishing the rest of the building to 6 7 CushyCrux has recently uploaded a cool-looking vertical farm on the Workshop, great for urban areas! Is it obvious that I’m a physicist yet? 19 build up on top of it. This half-assed attempt at blending old and new basically ruins the integrity and authenticity of the building. However, an example of where adaptive reuse doesn’t devalue the building’s authenticity is Hearst Tower in Chicago. Here, an attractive glass tower is built on top of the base of what was supposed to be a 1930s tower, so since the original intent was to build a tower anyway, the building’s authenticity has been kept intact. Good adaptive reuse should preserve at least some of the floors and roof structures, making a more authentic reminder of the history and purpose than a mere façade. Also, the new layer of construction should be distinctly recognisable and contemporary, not an imitation of the historic style. While this may seem somewhat counter-intuitive, this is done so that historic buildings are seen as series of layers that accrued over time, in which each layer reflects the values of the time in which they were built. By making clear what is new and what is old, it renders the structure as more honest. For example, the Louvre’s new pyramid addition (surrounded by the original historic building) is made of clear glass in order to maintain the integrity of the open courtyard. New layers can enrich the structure, especially when there’s interesting dialogue between old and new. 4.3 Preserving the Industrial Heritage Old industrial sites have the potential to turn into museums and even vibrant leisure and cultural parks, while reminding people of the city’s past. They can also turn into residential or mixed-use areas, by keeping the exterior structure intact while converting the interior into new architecture like Austria’s Gasometer City neighbourhood. In general, the afterlife of factories built in a city should be considered, as the new global market economy means many factories are only temporary structures. Factories could be designed that way, dismantled when no longer needed; or, through re-purposing, they can be longlasting buildings with a post-industrial future in the city, serving as a reminder of the city’s industrial heritage. 5 5.1 Integrating and Improving Slums Background on Informal Settlements Informal settlements are a consequence of the government failing to to provide land, shelter, infrastructure, and services for the urban poor. Thus, they are forced to squat on unserviced land, frequently on high-risk sites, steep and unstable land, and floodplains. In time, infrastructure and services are eventually introduced to the settlements; however, given the area’s limited accessibility, no potable water, lack of sanitation, and no services like education or health, these areas remain in a submissive condition compared to the formal city. These settlements can be demolished, only to turn up again elsewhere. Thus, the public sector should work on aspects that individuals can’t address on their own, such as infrastructure, mobility, accessibility, services, open spaces, income-generating opportunities, food sufficiency, and environmental challenges. 20 5.2 Rapid Urbanisation and Slums Medellin in Colombia had slums with limited access, which made it crime-infested. To enhance local mobility, gondolas (otherwise known as metro cables, a form of cable car) were introduced as public transit. Open spaces were carved out adjacent to metro cables, accompanied by schools and libraries and workplaces. Torrents for sewer systems were created to prevent sewage from falling into ravines, with promenades along these torrents. Homes in flood areas (e.g. flood plains of ravines) were relocated to other areas that were still nearby so that social ties were maintained. All of this resulted in crime rates plummeting. Planning ahead of projected informal settlements (which typically occur around expensive real estate of the city) can help mitigate the negative effects of slums. This fosters growth in appropriate sites while keeping areas that should be unoccupied free (due to their environmental importance, for example). Land should be assembled and spatial requirements of public realm envisioned, defining areas where communities will self-construct neighbourhoods. Such areas should be determined with appropriate spatial requirements to help settlements achieve higher socio-economic and environmental conditions, and keep this land free from unwanted occupation.8 5.3 Retrofitting Infrastructure and Services As mentioned earlier, many slums are located in haphazard areas, such as hillsides and areas with steep elevation. Making services accessible to such areas therefore involves working with elevation, not simply flattening the area and destroying the local community fabric. One great way of accomplishing this is by having multi-level recreational buildings that have elevators between floors for different level entries to it. Such buildings can have multiple purposes so that residents don’t have to climb steep stairs and descend long alleys to get to where they want to go. Other ideas include: • Making escalators (as opposed to stairs) for easy access to slopes.9 This is especially helpful for people carrying groceries, disabled people, pregnant women, and the elderly. • Narrow stairways with piping and electricity running underneath them, saving space. • Adding libraries to ends of alleys. • Adding walkways along below-sea-level areas, such as docks along Bangkok’s water markets. One issue in making slums in C:S is that we can’t have any house that’s not directly adjacent to a road, while informal settlements are frequently much more narrow and tightly packed. The only solution I can see to recreate this in C:S is to have wide (and deep), high density, RICO slum buildings that can go between actual tiny roads while having pathways within them, to solve the “needs road access” problem. Otherwise, services such as ambulances can’t reach them even though they can walk up stairs IRL, etc. 8 9 Most of this would be done with the public sector and NGOs in developing countries, as governments would build these already if they could. C:S doesn’t support escalator functionality, they’d just work as stairs, but you can pretend they’re escalators! 21 5.4 Combating Poverty and Urban Deterioration in the Ghetto People are poor for a reason, they aren’t just lazy! Furthermore, urban deterioration isn’t random. It usually stems from a changing economy, the city losing its industry, changing commercial preferences (people want larger stores), or people moving out causing property vacancies (feedback cycle). Turns out that hipsters can be useful sometimes, as arts can be used to revitalise communities. Pedestrian areas can be painted to beautify neighbourhoods, and “junk” can be used to make sculptures, benches, and spaces for public use. Artists can move in, contribute to the community with their projects, and local people will like the neighbourhood and speak proudly of it. To avoid gentrification, a “wish list” can be created to reflect the needs and wants of local residents. This could include places they don’t want demolished, stores they want kept, improvements to housing and services etc. This can make sure local “vibe” and residents remain there. Once this is created, the government can buy areas sought out by land developers to ensure it’s developed in accordance to local needs. Once they add what locals want, and code for what can be zoned where, then developers can come in and build what they want.10 To deal with urban growth, high rises can be restricted to areas on the fringes of the land, so that local character is maintained. Streets can be shut down and converted into public green spaces, providing locals with services while preventing through traffic. Minimum spatial requirements for low income housing11 (provided by the government) ensures a socially healthy mix of incomes in the neighbourhood. Places where different incomes would come and interact are essential; otherwise, further marginalisation of the poor occurs and they will not be affected by whatever positive changes you think you’re bringing to the neighbourhood. In fact, you don’t even need to demolish shitty looking houses to completely change the flair of the neighbourhood! Remove some of the road and turn it into public gardens/shrubs (Congo St in Dallas by bcWorkshop is a great example of this, look them up in Google Images), and renovate houses to add modern flair (for example, wood panels on the sides of shotgun houses). This involves talking with local residents12 and seeing what needs to be improved in their homes. One way of reducing crime in ghetto neighbourhood is by adding local community gardens on streets themselves. This reuse of street space reduces the amount of physical space gangs can use to mark their turf, reducing street crime and thus making streets safer while providing food for local residents, as well as a meaningful recreational pastime.13 Design may not be able to eliminate poverty, but it can make a difference! It can help in economic development, especially if the strategy is to attract tourism and other industries that are sensitive to the quality of the place. It can help in assembly and reuse of lands, needed by expanding institutions 10 11 12 13 In C:S, this would basically translate into you not demolishing important buildings and retaining the local character that you created, no matter how much better it might look with a new fancy building from the workshop. In C:S, that could translate into Level 1 housing, possibly added to an existing building via sub-buildings or simply via MoveIt! Go ahead, talk to your cims, that’s totally normal behaviour! In C:S, you can add 1x1 small farms if you actually want food, or you can just add some agriculture props such as vegetable rows from the workshop. These don’t have to be too wide/deep, as you still want walking space on the sidewalks. 22 and businesses, and provide employment opportunities. It can help ensure development targets local unemployed residents, to ensure openings fit them. It can use abandoned lands as places for urban agriculture or recreation. In C:S, don’t just demolish neighbourhoods and remake them with fancy new subdivisions — you’d be destroying communities IRL! Instead, find ways to make local lives better within the neighbourhood without displacing the poor and marginalising them further. Make it a home for everyone, including the poor. 6 Community, Neighbourhoods, and Human Interaction To successfully plan a city, one must understand the views of its users — their lifestyles, practices, and appropriation of different spaces. 6.1 Transformation of Urban Lifestyles Lifestyle is defined as a composition in time and space of daily activities and experiences that give meaning to the life of a person. It has three (3) dimensions — functional, sensitive, and social. 1. Functional: What makes every day practical. This includes the infrastructure, services, and accessibility available by various means of transport. Everyone has transport mode preferences and each is characterised by an anchor in daily activities related to proximity. 2. Sensitive: What promotes well-being. This includes the morphology of the built environment such as green spaces, quality of facilities, density, new versus old, and aesthetics. Each person feels good in certain environments and has their preferences. 3. Social: What promotes social relations. This includes public space types, accessibility, presence of facilities and intermediate spaces, and the possibility to articulate public/private division. We all design specific relations to each other and of the social anchor. Community life, neighbourly friendliness, reputation, etc., are all dimensions that refer to the social quality of a space and for which each has specific expectations. What has changed over the last forty years, in relation to these three dimensions, is that there is a diversification of models of aspiration. Prior to this, people had more similar goals. Now, there exists no singular quality of life, but rather qualities of life. One income can support several different lifestyles and allow the recipient to live in different neighbourhoods. Thus, since lifestyles are so diversified, we can’t identify them simply using classic variables such as income, education, and household composition. 6.2 Residential Mobility and Housing Choices Residential mobility (where people choose to live), like lifestyle, is dependent on three (3) logics — Rational, Social, and Sensitive. 1. Rational: Metric and economic factors. For example, the household determines where it can live based on income, family size, and the house’s distance from work/amenities. 23 2. Social: Once the rational factors filter out inapplicable houses, the remaining choices are prioritised based on what values a person has. For example, it may be important for the household to live near other family members, or have a big house for social status. People want to live in a place that resembles us and our background (cultural or otherwise). 3. Sensitive: When deciding between two homes that align best with their social values, the household finally chooses a home based on sensitive factors such as lighting, smell, and the overall wellness we feel in the neighbourhood. As discussed in the previous section, one’s lifestyle can be the same even as they gain income, and one can have a different lifestyle from someone else with the same income. Thus, lifestyle (as opposed to income) is decisive to explain choice of residential location. Do people want to live individualistic lives and not have to engage with neighbours every day, as in individual suburban houses? Or do they value community and want neighbour engagement, as in small apartments? Lifestyles can be grouped into two main categories, with corresponding residential preferences: Classic and Contemporary. • Classic: Lifestyles including residential aspirations similar to traditional values, regardless of household income. These prefer quiet residential environments, typically mono-functional with beautiful visual clearances on a human scale. Ideally within a neighbourhood that promotes security, being between oneself, and promoting a certain social status. Tends to prefer private individual transport over public transit. Ideal residence: single family (e.g. suburban) house that is newly built. • Contemporary: Less traditional lifestyles, more often led by dual-income households. Such lifestyles advocate social diversity, living together, lighter modes of transport, public transit, active cultural life, and ecological values. Prefer active residential environments that are intensive, mixed, dense, urban, and where cultural and artistic activity is high. Ideal residence: apartment in old building (loft) or in modern building. As discussed above, different lifestyles tend to live in different areas. However, even one single building block can host different lifestyles by having different building layouts (and adjacent alley/park layouts). Some buildings within that block can have more alleys and laundry rooms where people can meet (contemporary), while others can have parking next to the house for less interaction with neighbours (classic). Having a mixture of lifestyles in one area can be beneficial as such shared spaces are critical to de-stereotyping; when we face diverse people, we are challenged by our assumptions. One universally desired trait across all lifestyles is serenity. All households regardless of type want proximity to peace, nature, and green space. Homes geared for classic lifestyles can have individual yards, while their contemporary counterparts can have a shared community garden serve as a common yard. Each city (area) has different geographies and densities, so planning new neighbourhoods in a particular area should take this into account. For example, Bern has its neighbourhoods close to the city centre and in short reach with public transit, whereas Lausanne is more spread out and doesn’t have much public 24 transit between neighbourhoods. Much of this is due to constraints from local geography, and also the history of the city. Thus, each territory (Lausanne or Bern) will attract a different target audience, living different lifestyles. 6.3 Spatial Patterns that Promote Personal Communication The overall city should be a space where everyone can feel at home somewhere. This doesn’t necessarily more neighbourhoods; there may be too many already and not enough centres where they converge. Pedestrian and social areas can interest people from all backgrounds. The centre of city shouldn’t be a shopping mall competing with other malls, but rather a living space shared by inhabitants, commuters, tourists, etc. People value personal contact and crave human interaction even with technology — in fact, technology just makes it easier for human interaction. It serves as a tool for people with common interests to gather in groups (preferably in areas with wifi, of course). People aren’t isolated by technology as often thought. What is needed, however, is to create spaces that promote personal contact. If one’s “first place” is home and one’s “second place” is work, then one’s “third place” are places like cafés, book stores, hair salons, bars, and other centres where the community congregates and hangs out. A successful “third place” should have the following elements: • Stand on neutral ground, and not deter from one group or another. • Be accessible by all. • Function as a leveller so that all are equal. • Provide the ability for conversation to be the main activity. • Be a home away from home, much like how a library serves as a second home for some people. • Allow easy entry and not require major commitment to use them; for example, allow pedestrians to walk through it, or attach it to pathways many people travel. • Contain distractions; e.g. waterfalls which serve as a distraction from street noise while also functioning as a conversation piece. • Provide the ability for groups to use it for different activities, such as dance groups, exercise groups, basketball, etc. The idea of a third place is to function as a space where informal groups conduct activities that people can watch, join in, or move on. Such a space needs a connecting piece for people to walk through and see and sample all of the activities. However, the area must be made so that formal groups don’t take over. This can be done by, e.g., making only a half-court basketball court instead of a full court, not building a soccer field or baseball diamond (no matter how much formal groups may ask), etc. This way, the space is kept open for all whenever not used by specific formal groups. 25 6.4 Mixing Home, Work, Culture and Recreation Mixed-use buildings can function as places to shop, work, play, and live. They don’t need to be tall either! A hodgepodge of small buildings (ranging from 3 to no more than 15 stories) with mixed-use functions can work well like this. Culture is in fact created by these mixed-use spaces. These areas prevent forming streets that look unsafe at night because they’re dead, as mixed-use areas tend to be active 24/7. In general, they make places safer since there are eyes on the street all the time. Well-lit buildings can further help create the vision of a safe space at night, even when not in use (e.g. make a public library well-lit). Another benefit of having mixed-use areas is that parking can be used at all times of day, making land use more efficient. Well designed outdoor spaces can ensure mixed-use environments are lively even in cold climates. Roofs above shops can function as parks for local residents, as discussed in subsection 3.4. 6.5 Walkable Neighbourhoods Walkability is typically defined as the ability to walk (or take transit, depending on the definition) to weekly needs like shopping, school, etc. within 20 minutes. Most people walk for 10 minutes before deciding on another mode of transport, e.g. car or public transit. Grid street patterns allow far more walkability than winding and circuitous streets; one can traverse a much further distance in 10 minutes walking in a grid than long, uninterrupted curving streets without shortcuts. Aside from walking distance, factors such as density, modest setbacks for houses, shade (from trees), and well-maintained sidewalks with visual interests every 200 m or so all contribute to walkability. However, the most important factor is having a walkable commercial centre within easy range of one’s home. Old frontages may be difficult to adapt to modern supermarkets, so redevelop large vacant areas (e.g. at the end of a street) to form a modern shopping centre. For example, a local neighbourhood can have large stores on its north end, residential and low-commercial (for everyday needs) on its south end, and offices/entertainment in between. As traditional sprawling shopping centres become obsolete (which they are nowadays), you can retrofit these places to become walkable. Arterial streets can become more pedestrian friendly boulevards, with new infield development added in front of them. People can live above the shops with higher density development, streets become more pedestrian and bike friendly, and the local population grows. 7 7.1 Designing New Cities, Districts and Neighbourhoods Urban Form of New Places Most urban development is small scale, e.g. a project on a single lot, a block that’s redeveloped, a subdivision created, etc. Over time, these pieces add up to become a city, and it’s the designer’s role to ensure it’s the kind of city we want. One way to think about urban design is that it involves thinking in the next larger context. For example, when designing a house you’re actually designing part of a street, when designing a street you’re designing a part of a neighbourhood, when designing a neighbourhood you’re 26 producing a unique district of the city, etc. This line of thought prevents you from thinking that every new piece of the city needs to be self-contained and turned inward, and also reminds you that every project is part of a larger ecology. Green spaces naturally maintained by rainfall in a site can form an armature (frame) for a larger density development. Terraced houses can be built on hills, with valleys filled with green parks and cultural/recreational areas. To ensure everyone has a view of the valley, high buildings can be restricted to forming only on hill-tops. A good example of this arrangement is in Modi’in, Israel. Making sure that smaller buildings are in front of taller ones on streets makes pedestrians only aware of the small buildings as that’s all they see, even though tall towers are there too. Vancouverism insists that streets shouldn’t have blank façades and tall towers shouldnt block views of other buildings. Continuous front doors along residential streets are encouraged even if tall buildings tower over them; in this arrangement, town houses are at the base with apartments above and set back. On busier streets, continuous shopfronts aren’t to be broken by driveways or apartment lobbies. Milton Keynes is a nice example of a new city in that despite being a grid layout, each square is very uniquely laid out and through traffic in each square is discouraged. Pedestrian paths connect everything. However, precisely because it’s so spread out, it makes car owning a necessity and makes it difficult to provide transit services to all areas. 7.2 The Public Realm Public spaces that are shared are critical to de-stereotyping, as when we face diverse people we are challenged by our assumptions. Places such as theatres and stadiums are semi-public spaces — one must pay a fee to get in. Parks are fully public, as anyone can access them at any time. Squares and streets should stop being prioritised as places to get from A to B quickly, but rather to places where we can stay with our kids and talk to others. Boulevards can ideally be re-atriculated to nearby neighbourhoods. Pedestrian and semi-pedestrian areas allow residents of different income backgrounds to share the same space/areas, gives environmental benefits, and is aesthetically pleasing. Visual beauty with function is important as cities compete with other cities for business/growth. Note that the consistency of the public realm makes any variations in buildings along the street seem less important. Trees arching over sidewalks that are generous in space and offer rest areas, and interesting shopfronts, are all more interesting for pedestrian than architecture above. 8 Airport–City Connection This section discusses different approaches to integrating airports into your cities. 27 Figure 4: Airfront Model. Figure 5: Decoplex Model. 8.1 Airfront Model As shown in Figure 4, the Airfront Model involves locating the airport within the periphery of the city, with a small business district located between the airport and the city. The district would be based on commercial and industrial activity related to transport. Development of such a district would create jobs and thus have a positive social impact, and would involve minimal land use as it develops on the basis of existing economic activities that it will strengthen. 8.2 Decoplex Model Like the Airfront Model, the Decoplex Model involves locating the airport away from the city. However, as shown in Figure 5, a small linear industrial complex would be located by the airport. This development would focus on airport activity, e.g. transporting people and goods, aviation operations and maintenance, etc. Such a model develops a kind of aeropole which no longer focuses solely on transport but also contains a series of satellite activities, and would therefore involve minimal land use. This model has very little social and socio-economic impact, as these are often activities linked to offshore groups. 28 Figure 6: Airport City Model. Figure 7: Airport Corridor Model. 8.3 Airport City Model As shown in Figure 6, the Airport City Model is, in a way, an extension of the Decoplex Model. Activity surrounding the airport is no longer exclusively linked to aviation, and may also include economic parks, leisure parks, banks, sports centres, etc. At the spatial level, this model stretches around the airport, but remains compact and dense. However, there is a break in social dynamics because the airport competes with the city. It contains all the services and facilities that are normally found in the city. Sometimes there is even a residential component, which often develops competitively, compared to what is done in the city. In terms of governance, the airport itself plans and develops the territory. 8.4 Airport Corridor Model Unlike the Airport City Model, the Airport Corridor Model attempts to integrate and transition between the airport and city, as shown in Figure 7. The connection between the city and the airport is no longer a simple linear infrastructure, but an urban development, made up of several activities and functions. It’s an attempt at coordination between the airport, the city and the region, for the overall growth of the region. This model corresponds to the current dynamics between the city of Amsterdam and its airport. 29 Figure 8: AIREA Model. 8.5 AIREA Model Like the Airport Corridor Model, the AIREA Model attempts to promote regional growth by balancing forces of the city and those of the airport. The AIREA Model proposes the development of several economic, specialised nodes, which are connected between themselves on the one hand, and with the airport and city on the other hand. This is better visualised in Figure 8. This model is a spatially polycentric system as it applies modern zoning principles, where the mobility and availability of transport infrastructures are the basic conditions for its operation. Public authorities are heavily involved in planning and development, ensuring both international economic and local social needs are met. This model was created to avoid the development of airport megacities common in the U.S., which will be discussed in the next subsection. The AIREA Model corresponds to the current dynamics between the city of Berlin and its Brandenburg airport. 8.6 Aerotropolis Model The U.S. airport megacity model, called the Aerotropolis Model, involves the airport becoming the centre of a new city as shown in Figure 9. The former city itself becomes an “old town” and merely a district of this new city. The remainder of the new city is organised according to specialised zoning and without much mixing. This model consumes a lot of land, due to its spreading and low density. It’s based solely on economic development as the main driver. The aspects of quality of life, heritage, or other, are relegated to the background. This type of model poses a series of problems in terms of governance, as it encompasses different administrative jurisdictions, a diversity of actors, as well as areas that have developed spontaneously. It implies a complexity of coordination for the overall territorial development. 9 Public Transit This section discusses the theory behind public transit. To jump right into actual concrete guidelines, go to Appendix A. 30 Figure 9: Aerotropolis Model. 9.1 Catch-Bin Area Immediately around a transit stop, there are three (3) main “catch bin” or catchment areas: • Core Area = 400 m radius (5 min walk). • Primary Area = 800 m radius (10 min walk). • Secondary Area = 1200 m radius (15 min walk). In considering where people live in relation to transit, Primary and Secondary Areas are as important as Core Areas. However, physical and geographical barriers can limit these ideally circular catchment areas, meaning these may not be good locations for transit stations. If stops are close together, Core Areas can become a continuous corridor of development. At the intersection of two major transit systems (e.g. two lines sharing the same stop), the Core Area radius may be doubled. At each node (stop), the general land distribution should ideally be as follows: Streets and Open Space occupying ⅓ of the area, Office and Retail and Civic Uses occupying another ⅓ of the area, and Residential Uses occupying the final ⅓. Thus, there would be only a modest increase in density. 9.2 Understanding Modal Practices The means of transport used is a central indicator of lifestyles (see subsection 6.1) and of their diversity. Means of transport are a way to introduce ourselves, a way to build one’s relationship to time and to space. Thus, when planning transport, we must consider lifestyles and their different needs (and where these 31 needs are located, e.g. what lifestyle(s) lives where, where they converge, etc). One person can use different means of transport (including walking) to accomplish different things and go to different places even just in one city/neighbourhood. Usage of certain transport modes (rather than others) fundamentally refers to ways of living and organising one’s daily life and not just simply choices of transport modes. In many cases, transport modes need to be legitimised. For example, cycling may be seen by others as something only poor people do, so new people need to feel comfortable and not feel like they’re in the margins of society for cycling (or for using a new transport mode in general). These new transport modes must be legitimised by the population at large before some people adopt it. There are three (3) logics of action that cause different modal (transport mode) choices: Instrumental (choose fastest, cheapest, or combo of both), Personal Preference, and Habit. Even if one mode is cheaper or faster than another, some (many) people may still not choose it! Thus, one can’t assume people will use a particular mode for instrumental reasons alone. People may associate public transit with being slow, crowded, and/or constrained (not as independent as driving a car). So even if it’s faster and cheaper, personal preference may still prevent them from taking transit. Also, some people simply don’t plan on changing from car to transit (habit) because they’re so used to driving that even when they’re comparable they just use the car anyway. To account for the segmentation of these three logics of action, we have a typology made up of eight (8) specific provisions on the use of transport mode. This typology is made of three (3) dimensions: 1. Size of patterns that differentiate individuals using several modes vs. those using only one. • Only use car to move daily and hate other transport modes • Only use car to move daily but don’t hate other transport modes • Use other transport modes and don’t use car 2. Values that differentiate people who have a vision of transport modes according to their individual interest or according to common interest. • Multimodal comparators; people who are highly sensitive to mode prices and times (rational) • Civic environmentalists; people who avoid polluting modes as much as possible (emotional) 3. Attitudes that distinguish people according to their preferences of transport mode. • Motorists forced to use public transit (due to constraints like parking, traffic) but prefer car whenever they can. • People susceptible to alternative modes; prefer non-car but forced to use car sometimes. • People afraid of any motorised transport and avoid whenever possible. 32 Figure 10: Barbeque Effect and its relationship with increased energy consumption for transport in dense areas. 9.3 The Barbeque Effect In Switzerland, 37 % of trips are for leisure (e.g. going to a park) as opposed to only 23 % of trips for work and 22 % for shopping. Leisure transport is also frequently made with higher energy consumption modes of transport, e.g. car and plane. People in urban areas actually travel more frequently for leisure than suburbanites. This is because suburbanites already have many places nearby to spend their free time, e.g. gardens and forests, whereas urbanites need to compensate for lack of nature in everyday environment by travelling to it. This is called the Barbeque Effect — everyone goes out of the city to BBQ since you can’t in city.14 Taking leisure transport into account, the normal curve of “less dense = more energy consumption for transport” actually becomes false — the more dense you are, the more energy is consumed for transport, as shown in Figure 10. However, while some of these movements are compensatory for lack of green space in urban areas (and can thus be “fixed” or addressed), other movements are simply to explore other urban areas (e.g. travel from Toronto to Ottawa by plane). Thus, the graph shown in Figure 10 may be called into question as it doesn’t address this point. Furthermore, improved connectivity between the city and the green spaces outside the city (e.g. train, bus, or shorter distances) can address this increased use of transport. Can we really build cities that compensate for the BBQ effect? What would that look like, having virtues of both density and green space? And to what extent can we reduce leisure travel, since e.g. people go on trips on holidays (travel is what holidays are associated with) regardless of what is around their residential area? This is still an area being explored and these questions are still being investigated. 14 Yeah, I don’t get it either. 33 9.4 Seductive Engineering In a system where many choices exist, for a technical solution that is introduced to be successful, it must be attractive. It must resonate with what people want to do, their aspirations, and their constraints. In Geneva, they had trams with multiple lines sometimes sharing one road. You could be at one stop and take trams in multiple directions, thus avoiding having to change tram lines in the city centre since direct paths (to destinations) throughout the city were multiplied. However, transit authorities removed some of these multiple lines or “duplicates” to simplify the network, so that instead of one stop having 2/3 lines they’d only have 1. These lines are faster and have more trams (increased frequency). However, ridership dropped as people hated the fact that they had to change tram lines when before it was direct! The users in this case sought direct routes, as downtown public spaces are traffic congested so it’s unpleasant to change lines. Thus, even if there were improvements in speed and frequency, the old network was still considered better by users! Therefore, if we want to make a network to expand use of transport, we have to consider the sensitivity of the population. For new riders, it must attract/seduce their expectations and in this case their expectations weren’t to go faster but to go direct. Engineering with seduction means engineering keeping in mind public expectations and desires, not just efficiency or technology! If it’s very efficient but poorly received by consumers, it’s a bad engineering design! 9.5 Territories, Networks, and Forms of Urbanisation: A Note on Trams Trams have become more popular not only for promoting use of public transit, but also for reclassifying urban centres to make them more attractive to frequent as well as live in. Tram networks allow for a growing number of users. They offer smooth rides (that allow you to do work on it when seated), contain nice paths to stops, and allow for easier memorisation of the tram route due to its materialisation in the public space via its rails. Real estate around tramways increases in value and people want to live near them. However, trams don’t imply significantly increased transit usage in all cases. Speed, destinations served, and frequency are obvious factors that should be addressed. However, other factors to consider for trams include crowdedness; if there aren’t any seats available, then its attractiveness for a smooth ride and ability to do work on it goes down. In addition, a lack of unity with other transit modes is also problematic; if it has, for example, a different frequency than bus/metro, it would then not be in sync with the rest of the system and therefore people may simply continue using the bus/metro (and then maybe transfer to tram if needed) which would leave ridership the same as before. 9.6 Transit Adherence One of the biggest hurdles to using new transport modes is the last mile. Let’s say your house or office is 500 m away from the metro stop. A dedicated bike lane or pedestrian path between the metro stop and your house can make all the difference to whether you use public transit or not! These aren’t replacements for transit, but rather complement and enhance it. If pedestrian pathways to bus stops are poor, 34 or the route isn’t direct and is convoluted to take, then the adherence (effectiveness) of that bus line is diminished and people no longer view that transport mode as an anchor despite the number of stops it has. Cities are dynamic and not static. They grow and flux. Therefore, transport systems (and cities in general) should be built with the flexibility to change, add, and delete transit lines/modes when necessary; allow new projects to serve new players or new needs to graft to its own dynamics; and allow additional inter-modal nodes to be created as well as new centres and new developments. 9.7 Public Space Fragmentation: Resident Needs Vs. Visitor Wants While tourism and visitors (including commuters) make a city thrive, a city cannot be attractive without local satisfaction. Thus, local needs must be prioritised ahead of tourist needs, and transit/roads should be built for the benefit of the city as a whole. For example, making a train run through the centre of a city for the benefit of tourists and commuters visiting the city may result in the detriment of the adjacent areas and locals leaving, killing the life of that area. A lot of times, things that are interesting for tourists and visitors like historical sites, landmarks, etc., aren’t really that interesting to actual locals who live there. For them, where they live is much more interesting and worthy of consideration/note. For example, how many people in Toronto care about the CN Tower versus visiting Queen Street? Tourist attractions dont mean or imply that locals will visit or accept it as important! Their needs must be met too in their own neighbourhoods. Metro, monorail, and train routes right in the middle of the road that create physical barriers can fragment cities and neighbourhoods. Crossings should be added to help maintain flow across streets if such massive and divisive structures are unavoidable. Pedestrian walking time between transit stop and destination must be accounted for in addition to the actual transit travel time. Placing public squares and plazas next to “out of the way” bus lanes can help increase their use and attractiveness, but local desires around transport use must be taken into account as well. Public space projects can help sew neighbourhoods together, but this shouldn’t be limited to crosswalks and connectivity projects. Rather, it should include the activities and functions which are offered around these spaces (live, work, play), so these spaces should be placed strategically through functional diversity by favoring short trips. 10 Building Design Principles The guiding principles here place the highest importance on how a building — or site (e.g. collection of buildings) — influences the character and quality of the public realm and pedestrian environment. The guideline structure for each building type is organised by the following guiding principles. These are applied in different ways for different building types, as outlined in the guidelines in the appendices. The following principles apply for all sites and all building types. Follow these principles for all sites and buildings, and then look to the specific sections for institutional, neighbourhood retail plaza, tall, 35 mid-rise, townhouse/low-rise, and single residential buildings for additional guidelines that must also be followed. 10.1 Frame the Public Realm Position and design buildings to define and enhance the public realm, particularly as experienced by pedestrians. In an urban setting, the building’s primary design role is to contribute to the street wall and frame the public realm. That portion of the public realm might include parks, squares, or streets. A continuous street wall helps frame the street as a public open space, and encourages pedestrian activity. This is particularly important on streets with at-grade retail uses, which must directly engage with pedestrians. Small pocket parks or squares can especially benefit from a firm sense of enclosure, with building edges on one, two, or three sides. Such enclosure provides a desirable sense of completion or finiteness, and prevents public spaces from getting lost in larger, less defined surroundings. 10.2 Ground Floor-to-Street Relationship Activate the street by incorporating the most public and active uses within the ground floor. At the ground level, the design and scale of building façades and sidewalks should enhance the pedestrian experience by being visually interesting, active, and comfortable. Buildings should have continuous frontages of grade-related uses with direct access from public sidewalks. In a lively mixed-use urban setting, retail, commercial, and community uses are encouraged at street level with a high level of visual transparency and permeability, with many windows and clearly marked entrances. These active uses must be visible from the street to the pedestrian and motorists alike. Where retail isn’t possible or not permitted, consider live/work units at grade. In residential areas, having the front doors accessible from the sidewalk will provide a public-private interface, animate the street, and provide a higher sense of security and ownership. Where appropriate, upgrade and maintain the rear of centre/corridor building façades in much the same way as street façades, particularly when an opportunity exists to create active retail spaces such as back-of-lot cafés. Treat the rear or sides of sites with a positive edge such as a laneway, a walkway, substantial landscaping, or setbacks. Provide lanes at the rear of sites to transition between different land uses and to avoid a back-to-back condition, as shown in Figure 11. 10.3 Sense of Entry Provide visible and easily accessible pedestrian entrances from the public sidewalk. Primary entrances should face the public street, be easily accessible from the public sidewalk, and provide legible connections between the public realm and interior circulation spaces. Both drivers and pedestrians should easily recognise an entrance from the street. They should be prominent, highly visible, and of an appropriate scale to their function and frequency of use. Entrances are an ideal location to incorporate and integrate public/private uses with the building. Typically, the most vibrant and interesting streets are lined with active, street-related uses accessed by a series of entrances from the public sidewalk. 36 Figure 11: A continuous rear lane helps transition between the rear lots fronting onto the arterial street, and the side lots of the buildings on the local street. 10.4 Integrate Urban Open Space Projects shall include urban open space wherever possible as part of a larger functional and animated pedestrian environment, and exhibit a positive sense of place, not to simply serve as the setting for a building. A wide range of uses and amenities in publicly accessible urban open spaces can complement more intense building forms that will result from redevelopment to help create a more liveable city. Landscape spaces between buildings not occupied by driveways or pedestrian connections to create usable open space. New public parks, rooftop gardens, green roofs, promenades, streetscape improvements and urban squares, courtyards, mews, and semi-private front yards should be combined to form a coherent pedestrian- and bicycle-oriented urban open space system. Where private courtyards and outdoor spaces are visible from the public realm, consider the pedestrian experience and views. These spaces should enhance, and not detract from, the pedestrian experience of the public realm. Avoid plantings of monocultures as they invite potential problems of significant plant losses due to disease, insect, and/or fungal problems. 10.5 Light, View, Skyline, and Privacy The massing of buildings shall contribute to an interesting and varied skyline, and maintain an adequate view of the sky from ground level. Building height should reflect the importance of each street and respect surrounding context. However, the height of mid-rise and tall buildings is only one of the dimensions that influence the ground level perception of their mass and bulk. Basic design standards are required to control the spacing and proportion (width relative to height) of buildings in order to maintain the ‘sky view’. Buildings above the mid-rise or podium height should be designed as towers, and articulated in a manner to reduce their perceived bulk and improve their contribution to the skyline. Avoid placing equipment, vents, fans, and other utility equipment on elevations facing a street. Screen rooftop mechanical units and satellites, or incorporate into the overall building design to minimise their visual impact. New developments may enhance, or impede, views of heritage sites and landmarks, as shown in Figure 12. To lower the apparent height of a tall building, tree species that will grow tall can be effective in reducing 37 Figure 12: Height and built form along a streetscape can visually impede a vista (top left), or enhance a vista (top right). Similarly, new streets and built form can be used to reinforce existing views or create new views to existing landmarks (bottom). 38 Figure 13: The houses in this diagram have varied setbacks along an arc which creates a varied and more interesting streetscape. Figure 14: The tall building steps back to protect an important view from the public realm. the apparent or perceived height of the building at grade. In areas with varied front setbacks, design building setbacks to act as a transition between adjacent buildings and to unify the overall streetscape, as shown in Figure 13. Respect the existing general pattern of side spacing. 10.6 Prominent Sites Provide special architectural treatments for buildings on corners and in other prominent locations through the use of taller elements, projections or façade treatment. A prominent site may include a street or view corridor terminus, a major intersection or high-order transit node, views of key public open areas or natural features, and city landmarks. A prominent site may not necessarily be a particular building (like in Figure 14), but may also be a general space, as shown in Figure 15. Buildings located on corner lots or other prominent sites present an excellent opportunity to highlight their unique location. Position buildings toward key intersections to emphasise the pedestrian realm at corners. Design strategies include articulated corners, projecting and receding balconies, and accentuating features at various scales. The primary entrance to buildings on corner lots should be located at the corner, with architectural features such as double height lobbies, special rooflines, or other building elements like porches or turrets. Provide significant architectural or landscape features at the corners of sites or intersections to make them stand out from the building pattern along the rest of the block. Maximise the landmark opportunities of particularly prominent corners such as at the intersection of 39 (a) A prominent site at a view termi- (b) Prominent sites framing an im- (c) A prominent site at a unique lonus. portant public open space. cation in the City structure. Figure 15: Different examples of prominent sites that aren’t landmark based. two arterial streets, at a significant bend in a street, or at the terminus of a long view. Public spaces at prominent points may also highlight building and site significance, and contribute to an active public realm. 10.7 Scale Transition The interface between redevelopment sites and neighbourhoods shall respect the character of the neighbourhood and minimise adverse impact by creating a comfortable built form transition. Larger buildings should relate to their surrounding context, with a sensitive and graceful transition in scale to adjacent uses, especially to existing low-rise and mid-rise residential buildings, historic structures, and public spaces. The tallest buildings should be located the furthest away from the adjacent uses, with all mid-rise and tall buildings subject to height limits and angular plane controls that may differ with context and geography. Design sites to minimise impact on existing site grades through creative building and design solutions such as stepped building foundations (floors), alternative building footprint(s), and terracing. Where possible, match grades to surrounding properties and to street grade. Use natural grades across site, and avoid retaining walls. If absolutely necessary as the natural grade can’t be respected, provide an integrated retaining wall system that creates a natural transition in grade across the site and contributes to an attractive streetscape. Retaining walls must be located entirely on private property. 10.8 Façade Treatment Design visually permeable, well-constructed building façades of durable materials with a wellconsidered architectural rhythm and colour palette. As a general principle, new developments should have an exemplar architecture that is of ‘its time and place’. The building façade is composed of many elements that will ultimately give the building its look and feel. It’s with the façade that a building can truly begin to express individuality and achieve design excellence. The designer may use many tools — material, colour, articulation, fenestration, projections — to achieve their objectives. 40 The scale, articulation, rhythm, proportion, pattern, colour, texture, and materials of buildings must be complimentary to nearby buildings, existing and new. Avoid large expanses of blank side wall. Where feasible, cluster utility areas together or incorporate them within streetscape furniture in order to minimise their visual impact. Exterior lighting should be used to highlight façade detailing and indicate primary entrances at night. One of the key goals to intensification and redevelopment should be to achieve superb building architecture that improves the public realm. Avoid buildings with a pastiche of architectural styles and details, as they don’t help create a coherent identity for the development and by extension, the city. New developments should respect and fit within their context and improve their overall setting by enhancing the pedestrian realm. 10.9 Building Projections Integrate projections such as canopies, private balconies, porches, outdoor terraces and bay windows into the overall form and design of the buildings. Projections add visual variety and interest to the building façade, and enhance the inside-to-outside connection. Projections such as bay windows, balconies, canopies, awnings, porches, and sunshades provide weather protection for both the pedestrian and the building. Entrance canopies provide cover from sun, snow, or rain. Awnings provide similar protective cover for the retail activity at ground level. Well-designed projections can provide an additional layer of detail and individuality to a building, and enrich the pedestrian environment. These elements add visual interest to the front façade, enhance the prominence of the entrances, and provide transition in scale from the sidewalk to the main wall of the building. These elements also often help new developments fit better within the existing neighbourhood context. Incorporate site features that create a comfortable transition between different uses. 10.10 Vehicular and Pedestrian Circulation Minimise the impact of vehicular circulation and access routes to parking and servicing on the pedestrian realm. With intensification and redevelopment comes the opportunity to reconsider the role of the private vehicle and the space it consumes. New development must balance the need for vehicle parking with the requirements of an active urban environment. Prioritise pedestrian and cyclist circulation and connectivity with adjacent sites. Surface parking should be minimised, and the design of parking and service areas should be considered secondary to the primary site and building features. Parking and service areas visible from adjacent streets, or that back onto residential properties, should be screened with walls, fences, trees/bushes, and landscaping. Landscape buffers should have a minimum dimension of 3 m, and incorporate materials that need little or no maintenance (e.g., groundcovers instead of monocultural grass). Provide just enough lighting to ensure safety and security. Break down the scale of larger parking lots with planting islands that may provide additional opportunities for stormwater management (see Appendix L for more details). 41 10.10.1 Pedestrian Connections Provide pedestrian walkways between building blocks/sites, through parking lots, and through covered building arcades. Pedestrian connections should be continuous, barrier-free, and lead directly to destinations. Entry locations to pedestrian walkways should be easy to find, clearly visible, safe, and have direct connections to the public sidewalk. Use distinctive pavement or markings (e.g., painted patterns) to provide visual identification of pedestrian routes. Provide pedestrian-scaled lighting, benches, trees or other landscaping, and planters along pedestrian connections to enhance visibility and security. Provide clear sightlines allowing view from one end of the walkway to the other. Where a transit stop is located within walking distance of an important site, provide a direct pedestrian connection between the transit stop and the building’s main entrance. Where appropriate, orient active uses such as retail stores or cafés to front onto pedestrian connections to provide an active pedestrian realm. 10.10.2 Service and Loading Areas Locate and design/landscape waste and loading areas so that they aren’t visible from the public street. Ideally, use the building mass or other architectural elements to visually screen undesirable site elements from the street or enclose them within buildings on the site. When this isn’t possible, screen loading, servicing, and utilities with low walls or fences and extensive landscaping (e.g., plant materials, berms). Screening and enclosure of such areas should be done using materials that minimise visibility (e.g., no chain-link fencing), similar materials as the primary building, and that maintain appropriate sightlines. Pave loading and servicing areas with an impervious surface of asphalt or concrete to minimise the potential for infiltration of harmful materials. 10.10.3 Parking Where feasible, incorporate shared driveways in order to reduce the extent of interruption to pedestrians. Underground parking structures are encouraged over surface parking lots to conserve land, promote compact development, and to minimise the urban heat island effect. As your city intensifies and develops over time, such parking structures should replace surface parking lots. Locate and design parking lots and internal drive-aisles to minimise the number of vehicle crossings over pedestrian connections. For corner sites, parking areas shouldn’t be located on an exterior side. Where parking areas are situated adjacent to the sidewalk, provide a landscaped area of at least 3 m wide between parked vehicles and the sidewalk. This buffer should be located within the private realm, so as not to reduce the total sidewalk width. See Appendix L for informative surface parking lot design guidelines. 42 A Transit-Oriented Communities Design Guidelines The following section is derived from TransLink’s Transit-Oriented Communities Design Guidelines, July 2012. A.1 Common Terms and Definitions Below are some terms used throughout this section as well as in subsequent portions of this document. Desire line – Preferred travel paths (usually with respect to walking and cycling) based on the convenience of travelling from one location to another; desire lines can be sidewalks and formal routes or informal paths. Frequent transit network – A network of corridors along which transit service is provided at least every 15 minutes in both directions, throughout the day and into the evening, every day of the week; a high frequency and span of transit service within a corridor, which may be provided by a single route or by a combination of routes and/or technologies within the same corridor. Frequent transit node – The 400 m (for stops) or 800 m (for stations and exchanges) area around transit passenger facilities where two or more frequent transit services intersect. Rapid transit – An urban transit service characterized by high carrying capacity and by speed, frequency, and reliability (high speed and reliability are usually achieved through separation from other modes of travel); typically provided by transit technologies such as rail rapid transit, light rail transit, and bus rapid transit. Station/Stop area – The 800 m radius surrounding a rapid transit station (the radius is 400 m for local transit stops); operationally, radius is typically represented as an ‘as-the-crow-flies’ distance, but can also be based on actual physical distance by way of available paths that can be covered in a 10-minute walk (5 minutes for stops). Urban centre – An important focal point for jobs, homes, institutional facilities, services and entertainment, community and cultural activity, and future growth; generally characterized by higher population and employment density and more trip generators when compared to surrounding areas. Urban Centres are intended to be the region’s primary focal points for concentrated growth and transit service. A.2 Destinations: Coordinate Land Use and Transportation A.2.1 Ensure that major destinations are lined up along a reasonably direct corridor so they can be served by frequent transit Transit is most cost-effective when services are well used along the entire length of a corridor in both directions. To encourage a more efficient pattern of usage, ensure that frequent transit corridors, particularly those with rapid transit, have major destinations (or anchors) at or near both ends. Without 43 anchors, transit ridership is likely to be low at either end, which reduces transit efficiency. The strongest anchors include major institutions such as colleges and universities, shopping centres, and large mixeduse developments. Major employment districts are also strong anchors. To support transit as a convenient travel mode, locate major trip generating uses in Urban Centres and frequent transit nodes/corridors to reduce the length of trips to access them. To increase the attractiveness of transit, locate major trip generating uses of region-wide interest within 800 m of the existing or planned rapid transit network (or within 400 m of transit passenger facilities for frequent transit corridors) to ensure convenient access by transit over longer trip distances. Locate major destinations at mid-points along frequent transit corridors, particularly where they intersect with other frequent transit corridors, to promote shorter trips, passenger turnover, and better-utilised transit capacity. Avoid long gaps between destinations by discouraging ‘leap frog’ development, or development far from established developed areas. Avoid spurs and diversion-shaped routes. A.2.2 Encourage the highest intensity of development in Urban Centres and at frequent transit nodes Destinations are best connected to the rest of the region when they are located in Urban Centres or at frequent transit nodes along frequent transit corridors. Encouraging development in Urban Centres serves to increase their attractiveness for office, commercial, retail, leisure, and entertainment activity, which in turn increases the demand for and the effectiveness of transit services. Locate transit stations and exchanges adjacent to, or integrated into, major destinations. Ensure a mix of land uses – including active uses such as retail, restaurants, and entertainment – at transit nodes to reduce walking distances between destinations and to promote pedestrian activity. A.2.3 Focus additional growth toward existing and planned frequent transit corridors Support future frequent transit service by strategically directing and phasing development toward a limited number of the most feasible frequent transit corridors first. Support transit use and efficiency by focusing development within a 5–10 minute walk (400 m to 800 m) from transit stops and stations, respectively. Plan for a development density that is appropriate for the type and frequency of transit service planned for each corridor. A.3 Distance: Create a Well-Connected Street Network A.3.1 Provide fine-grained street networks See subsubsection B.10.1. A.3.2 Make walking and cycling access to frequent transit as direct as possible The distances people are willing to walk to transit vary depending on length and purpose of the trip and quality of the pedestrian environment, as well as on weather, topography, and demographics. Generally, people will walk further to access limited-stop transit services than local services and walk further still for rapid transit services. Paths of travel to and from transit passenger facilities should be as direct and 44 pleasant as possible, both to minimise the distance people are required to walk to transit and to maximise the number of people who have convenient access to it. Transit passenger facilities and access routes to and from them generate concentrated levels of activities by pedestrians, and should therefore be designed to create an environment that is safe, accessible, easy to use, and secure and comfortable for all users – especially for these non-car modes. A 5 % increase in walkability as measured by these traits was associated with a 32 % increase in walking for transport. Walking and cycling trips on their own are also important for transit-oriented communities to enable short trips without a car, reduce peak hour crowding on transit, and reduce congestion on roads. Locate passenger facilities at intersecting frequent transit corridors as close as is practical to minimise walking distances for those transferring between them. In communities with significant changes in topography (e.g., steep slopes) that may affect walking and cycling use, plan connections to transit that maximise the directness of travel to improve the attractiveness of these modes. A.3.3 Plan for coordinated, multi-modal transportation networks See subsubsection B.10.2. A.3.4 Locate frequent transit passenger facilities at accessible places on the street network Transit passenger facilities, such as bus exchanges and rapid transit stations, are important focal points for community and transportation activity. Wherever possible, facilities should be located where they provide convenient access to pedestrian and cycling networks, enable efficient inter-modal connections, and support the creation of higher density, mixed-use development. Distances to surrounding uses may be reduced, not only by creating more connections, but also by locating transit facilities where existing connections intersect. Integrate transit passenger facilities into existing or planned sites on the most active and well-used streets. A.4 Design: Create Places for People A.4.1 Design multi-modal streets Medians and refuge islands: Signal cycles should be timed to allow the slowest range of pedestrians to cross the intersection in one movement. Where it’s necessary to maintain short signal cycles on wide arterial streets, comfortable median or refuge islands allow the slowest pedestrians to cross in two signal cycles. Provide medians and refuge islands on wide streets to serve as a ‘safe’ area between lanes of traffic where pedestrians can wait to finish a crossing. Transit: Increase transit speed and reliability on arterials by designing for transit priority. On streets where transit operates in mixed-flow conditions, provide transit ‘queue-jumper’ bypass lanes at congested intersections to reduce transit delays. Design streets so the lanes where transit vehicles operate are at least 3.5 m wide to ensure safe and efficient transit service. Where appropriate, provide signal priority for transit vehicles at traffic signals. 45 A.4.2 Design great public spaces Transit use will be low if safe, efficient, and attractive pedestrian routes are not available — after all, a person must walk to their bus stop. To support transit-oriented communities, the public realm should be both functional and attractive, and it should be inviting for those walking, cycling, or lingering. Pedestrians, particularly those travelling to and from or waiting for transit, must be offered adequate shelter from inclement weather to promote the use of transit services. Furthermore, a person must feel safe and secure in the public realm before walking becomes an attractive transportation option. Creating great public spaces supports the interrelationship between placemaking, good design, and the experience of delight in the urban environment. To create a safe environment attractive to pedestrian use, follow the pedestrian guidelines discussed in subsubsection B.3.3. A.4.3 Seamlessly integrate development with frequent transit and the public realm Closely integrate transit stops and stations into building design, where possible, in ways that create a strong identity for transit and enhance the public realm. Maintain sightlines toward local landmarks and public spaces to reinforce legibility and aid in pedestrian wayfinding. A.4.4 Design parking to support a pedestrian-oriented urban realm See subsubsection B.3.4. A.5 Density: Concentrate and Intensify Activities near Frequent Transit A.5.1 Focus density in Urban Centres and around frequent transit corridors and nodes to support a strong demand for transit service Concentrate the highest density of homes, jobs, and services in Urban Centres and along frequent transit corridors. As the distance from frequent transit increases, scale down from higher to lower residential and employment densities, including building height and massing, to match the character of the surrounding neighbourhoods. Reserve the highest densities for Urban Centres and well-connected frequent transit nodes, including rapid transit stations and nodes where two or more frequent transit corridors intersect. Provide a mix of more affordable, transit-oriented housing types within 800 m of transit passenger facilities. Locate services and housing for seniors and people with disabilities near frequent transit stops and stations. Encourage affordable housing near frequent transit to increase the mobility options for residents of such housing types. Integrate mixed-used development into the design of transit station areas, where appropriate, to promote complete communities, higher transit ridership, and efficient use of transit services. A.5.2 Plan for density that supports community character and promotes quality of life Promote family-friendly development near transit, such as multi-family housing, child care facilities in mixed-use development, close proximity of schools, and creation of park space. Redeveloping parcels 46 near frequent transit in existing urban areas can help to maximise land efficiency and create transitoriented development. A significant opportunity lies in single-family neighbourhoods where infill units such as laneway houses and secondary suites can increase density while retaining the character of the area. It’s important to develop and phase new sites adjacent to existing developed areas, to facilitate the efficient provision of urban services including transit. New street networks should be designed to extend existing networks, and to support walking and cycling. In new undeveloped areas, high-density development should only be considered in areas that are served by, or could efficiently be served by, frequent transit. A.6 Diversity: Encourage a Mix of Uses Most of the traffic reduction benefits of transit-oriented communities occur not because of increased transit ridership, but rather because of increased walking for the 80 % of household travel that isn’t commute-related. Transit-oriented communities encourage a mix of land uses at both the neighbourhood and the corridor scale. At the neighbourhood scale, a mix of land uses such as homes, offices, shops, parks, and entertainment in close proximity creates an environment where many needs of daily life can be met within a short walk from home, work, or transit. Such places feel safe and lively because different types of uses are active at different times of day. A built form that supports a mix of land uses can also allow a community to be more resilient over time, adapting to a changing economy and changing demographics. At the transit corridor scale, a mix of uses encourages ridership in both directions throughout the day and evening, promoting better and more efficient use of transit service and capacity. In communities where most of the basic needs of daily life are available within walking distance, owning and using a car becomes an optional, rather than daily, requirement. A.6.1 Provide a mix of uses along frequent transit corridors to reduce peak crowding and spread travel demand throughout the day Land use diversity within transit corridors can help balance the timing and directionality of transit demand, and more effectively utilise transit capacity. Balancing the distribution of homes, schools, and employment locations along a transit corridor will enable transit to be well-used in both directions during peak periods, rather than being overcrowded in one direction and underused in the other. Distributing other land uses with more variable travel demand – such as retail centres, civic institutions, and entertainment venues – along a transit corridor (preferably in Urban Centres along the corridor) can also help ensure that transit demand is more evenly distributed throughout the day. Such distribution also generates transit demand on weekends. A rich mix of pedestrian-friendly uses and housing types, tenures, and price points distributed along a corridor helps to optimise transit utilisation. A.6.2 Encourage a mix of land uses immediately adjacent to frequent transit facilities Areas within 200 m of transit facilities (especially stations and exchanges) are particularly valuable to encourage a mix of active land uses. People often like to combine tasks in one trip – such as picking up 47 coffee on the way to work, getting groceries on the way home, or dining at a restaurant on the way to a night out – and, therefore, convenient access to goods and services makes transit much more attractive. Providing retail and community services near transit can also promote local business opportunities and can help to create a lively street life, a pleasant pedestrian environment, and a safe and secure public realm. Promote the location of grocery stores (both large and small) near transit stations and/or at frequent transit nodes to support combined transit-shopping trips and walkability within higher density areas near transit. A.6.3 Encourage a mix of uses around transit nodes to create complete neighbourhoods Encouraging a diverse mix of land uses (residential, commercial, recreational, and civic) – for the wider 400 m area around bus stops and frequent transit corridors and the 800 m area around rapid transit stations – can help create neighbourhoods where home, work, shopping, recreation, and transit services are within walking distance. Such neighbourhoods enable residents to meet many of their daily needs within walking distance and to combine several errands on the same trip. This strategy supports both a higher walk and transit mode share for trips as well as reduced vehicle kilometres travelled. Encourage higher-density office uses as close to frequent transit passenger facilities as possible, to support convenient access by transit for employees. Locate schools (particularly secondary schools and postsecondary institutions) near frequent transit nodes wherever possible, to allow and encourage students to use transit. Invest in parks, plazas, and other public spaces within walking distance of frequent transit nodes to ensure that residents, workers, and visitors have access to green space and associated recreation facilities. Avoid lower-density and auto-oriented uses – such as gas stations, warehouses, storage facilities, vehicle services centres, and drive-through facilities – near frequent transit nodes. A.6.4 Provide an active street life with a mix of community services and fine-grained retail spaces Flexible and diverse retail allows families to meet their daily needs on foot, maximising time for other activities. Fine-grained retail and community services such as community health centres, cafés, and bookstores allow for chance encounters that encourage a sense of community. Families require easy access to pharmacies and fresh, healthy, and affordable food. Buildings lined with active uses, such as retail and lobbies, generate a vibrant, healthy street life. This is especially important during winter months. Active and animated building frontages allow for eyes on the street and informal supervision of children. A.6.5 Provide a mix of housing types near frequent transit passenger facilities to create inclusive communities and promote equitable access to transportation A mix of housing types and tenures at a variety of affordability levels located near transit passenger facilities can promote access for those segments of the population that are more likely to use or depend on transit to meet their transportation needs. Housing mixes can also allow communities to support residents at different stages of their lives, including students, single adults, families with children, and seniors. Diverse residential populations support transit use and activate areas around transit stops at different times of the day and week. 48 Encourage the location of low income, affordable, and seniors’ housing units near frequent transit nodes and along frequent transit corridors to support transit-dependent citizens. As people live longer lives and the share of the city’s population of seniors increases, mobility issues will become an increasing challenge. Transit-oriented community design supports seniors’ mobility by providing more services and activities within walking distance, facilitates ‘ageing in place’, and provides frequent and accessible transit services. Enabling seniors to be active by increasing the walkability of their neighbourhoods and providing convenient access to the transit system greatly increases their level of mobility and independence, provides opportunities to stay active and involved in society, and improves the effectiveness of both fixed-route and customised transit services.

APPENDICES A2 How the 6 Ds Relate to Transportation Outcomes The 6 Ds framework for transit-oriented communities is based on empirical research into the relationship between the built environment and transportation outcomes. This appendix summarizes some of the evidence behind each of the 6 Ds. A large and growing body of research demonstrates how community form shapes travel behaviour. A recent comprehensive review of the literature on how individual and household travel behaviour relates to differences in the built environment analyzes and summarizes the research on how VKT (Vehicle Kilometres Travelled), transit use, and walking vary with respect to differences in community form (Ewing and Cervero, 2010).1 These variables are of particular interest to TransLink and its partners because they relate to the regional and municipal goals of increased walking, cycling, and transit, reduced greenhouse gas emissions, and improved air quality. These relationships are stated in terms of elasticities, which describe how a percentage change in one variable affects a percentage change in a second variable. For example, if a 100% increase in variable A corresponds with a 50% increase in variable B, then the elasticity of A with respect to B is 0.5. All of these relationships are what economists call 'inelastic', meaning that a given percentage difference in any of the built form variables corresponds with a more modest difference in travel behaviour. Inelasticity occurs because other factors besides built form – including, income, geography, culture, and habit – influence travel behaviour. Though inelastic, these relationships are far from unimportant. In their meta-analysis, Ewing and Cervero find that by following through on land use and transportation visions using the tools available, more transit-oriented communities can meet their region’s goals for mode shift and a more sustainable transportation system (while also helping to achieve other important policy goals). 1 The most recent and comprehensive meta-analysis of the literature on this topic, this review is organized to compare disparate findings and measures across the available studies. The authors’ analysis reveals the elasticity of VKT (Vehicle Kilometres Travelled), transit use, and walking across a number of variables that represent different aspects of the built form. See the authors' summary table of their research on p. 143. 53 TRANSIT-ORIENTED COMMUNITIES DESIGN GUIDELINES 135 A. APPENDICES A. APPENDICES A2 How the 6 Ds Relate to Transportation Outcomes The research shows that destination accessibility – how easy it is to reach homes, businesses, and other destinations using a particular mode of transportation – has an important relationship with how people move around. The closer and more connected a community is to the centre of the region, for example, the fewer kilometres residents will need to drive (on average, a 10% decrease in the distance to downtown corresponds with a 2% decrease in VKT). Similarly, when more jobs are accessible by way of transit, people use transit more often (a 10% increase in the number of jobs accessible by transit corresponds with a 0.5% decrease in VKT). The distance a person must travel to reach a transit station or stop also corresponds strongly with choice of travel mode; for example, a 10% decrease in the distance from transit along the shortest street routes predicts, on average, a 2.9% increase in transit ridership and a 1.5% increase in walking. When thinking about community design, this finding has two important implications: the more homes, businesses, and other activities that can be located near transit, the better utilized transit will be and the less people will need to drive. As traveling to transit occurs not ‘as the crow flies’, however, but by using the available streets, a well-connected street network is equally essential for reducing traveler’s effective distance to transit. Research shows that street connectivity and block length have strong relationships with walking and transit use; for example, a 10% increase in intersection density corresponds with a 3.9% increase in walking, a 2.3% increase in transit use, and a 1.2% decrease in VKT. In addition to being important indicators of effective distance to transit, block length and street network connectivity are often used in transportation research to represent design quality. Short blocks and well-connected streets contribute to a higher-quality pedestrian experience and pedestrian realm, and they often occur in places where other elements of good design, such as adequate sidewalks, are also in place. Because of the importance of details and context, other aspects of design quality are difficult to quantify. 2 2 Other, more tailored measures of design quality tend to be complex – in that they try to address the multitude of factors that make up good design through multipart indices – and/or they require observational data that is not feasible to collect on a regional scale. 54 136 TRANSIT-ORIENTED COMMUNITIES DESIGN GUIDELINES A.

APPENDICES A2 How the 6 Ds Relate to Transportation Outcomes The research shows clearly that land use density alone – without walkability, a mix of uses, and good transit access – does not significantly reduce driving: when all other factors are excluded, a doubling of density corresponds with just a 4% decrease in VKT. Density is the most important factor, however, allowing more people to live and work near good transit (as discussed in the distance findings above) and creating a market for a mix of uses within walking distance (see diversity findings below) are also critical. As a primary causal factor, density by itself is a weak predictor of transportation behavior; however, density combined with transit provides an exceedingly important precondition for other factors that reduce driving and promote transit and walking. Research also shows how a diversity of land uses (including residential, commercial, industrial, institutional, and recreational) promotes walking and transit ridership and reduces driving. A common way to measure land use diversity in the transportation research is to create an index that assigns a high value to areas with a broad mix of land uses and a low value to areas with just one use. When land uses are more mixed, more daily needs can be met within walking distance: on average, a 10% increase in land use diversity corresponds with a 1.5% increase in walking (as well as a 1.2% increase in transit use and a 0.9% decrease in VKT). Though not documented in the Ewing and Cervero analysis discussed above, an extensive body of research demonstrates the important influence of demand management policies on travel behaviour. Numerous studies show that employer-based TDM programs reduce employee vehicle commute trips by up to 36%, with the largest reductions achieved through parking pricing.4 The literature also shows the primary importance of the price and availability of parking on choice of travel mode. Studies reviewed by the Victoria Transportation Policy Institute, for example, demonstrate that an average increase of 10% in the price of parking corresponds with a 1% to 3% decrease in vehicle trips.5 4 Willson and Shoup (1990); Comsis Corporation (1993); Valk and Wasch (1998); Pratt (2000). 5 Kuzmyak, Weinberger and Levinson (2003) and Vaca and Kuzmyak (2005) as documented in Litman (2012). 56 138 TRANSIT-ORIENTED COMMUNITIES DESIGN GUIDELINES B Complete Street Guidelines The following section is derived from the City of Toronto’s Complete Street Guidelines, April 2017. Complete Streets provide for all road users – pedestrians, bicyclists, transit users, and motorists of all ages and abilities. The implementation of Complete Streets results not only in improved conditions for cyclists, pedestrians, seniors, and children but also supports vibrant, healthy communities. Evidence shows that Complete Streets: • Provide better and more transportation options; • Improve safety for cyclists and pedestrians; • Reduce traffic congestion; • Reduce greenhouse gas emissions; • Create more walkable, and therefore liveable, communities; and • Stimulate economic growth with increased shopping activity, sales, and property value. There is no “one size fits all” solution or specific design standards that can be universally applied. Surrounding context and local community inform the best solution, resulting in many kinds of Complete Streets. How a street is “completed” is unique based on numerous variables including, but not limited to, surrounding community context, role of the street in the overall network, and the traffic volume for all travel modes. B.1 Street Types Street types should be used to establish a starting point in the complete streets design approach. Not every street will fit neatly within a specific street type, and some streets could be combinations of two or more street types. A street’s type may change along its length, as different segments have different land uses and contexts. Furthermore, a street’s type may evolve over time. This isn’t an exhaustive list of every type of possible street that exists, but is intended as a starting point in the complete streets design approach. Each street type includes a brief description, a series of key design objectives, and an aspirational example rendering to help illustrate what such a street could look like. It’s important to remember that the renderings show one visual illustration of how a street of this type could be designed. The renderings don’t depict exactly how every street of that type must be designed. 57 Toronto Complete Streets Guidelines 2.3.1 Street Types Civic Street 2.3.1 CIVIC STREET Civic Streets are streets with symbolic, cultural or ceremonial importance in Toronto, often distinguished by their landmark quality, and unique role in the civic life and identity of the city. These streets are destinations typically lined with clusters of civic, institutional, government, cultural buildings, significant open spaces or other public landmarks. Civic Streets are typically found in the older historic parts of the city, such as University Avenue in the Downtown, where they are often used for special city-wide events, parades, and public demonstrations. Civic Streets can also be found in local neighbourhoods, lined with important neighbourhood civic buildings and destinations, including schools, libraries, and community centers, as well as neighbourhood public parks and open spaces. On-street parking is sometimes provided on Civic Streets. c: Marcus Mitanis Some Civic Streets have wayfinding totems. Some Civic Streets have planters and unit paving. 58 24 While they share many similar design objectives, ‘local neighbourhood’ Civic Streets are different from more ‘city-wide’ Civic Streets. They have fewer visitors from outside the city and other neighbourhoods, host fewer special events, and have a less distinctive quality of materials and furnishings. Toronto Complete Streets Guidelines 2.3.1 Street Types Civic Street For illustrative purposes. Provide convenient and attractive bikeway design options and bicycle parking. • Seek ways to integrate green infrastructure, including tree plantings and other landscaping treatments, to meet environmental objectives. • Use high-quality and distinctive materials, furnishings and public art to create a sense of character and identity, especially for Civic Streets of city-wide importance. • Consider ways to reduce sidewalk obstacles and clutter such as by using building setbacks and burying overhead utilities. 59 • DESIGN OBJECTIVES • Seek ways to enhance the views, connectivity and experiences of adjacent civic buildings and public spaces like plazas and green space. • Provide wide sidewalks and boulevards to attract and support high levels of pedestrian activity and special events. • Provide pedestrian amenities such as benches/seating, lighting, and wayfinding. • Provide convenient and attractive transit options to access important destinations. • Provide appropriately located offstreet parking and access such as side streets parking lots, garages, lanes and parking at the back of buildings to augment parking supply, accommodate loading and minimize driveways, curb cuts and conflicts especially where space is constrained on the street itself. Time-of-day parking restrictions may be used for on-street parking. 25 Toronto Complete Streets Guidelines 2.3.2 Downtown and Centres Main Streets have sidewalks to accommodate many people walking, like this one in North York. A busy sidewalk with pedestrians and window shoppers on a Downtown and Centres Main Street. DOWNTOWN & CENTRES MAIN STREET Downtown & Centres Main Streets are vibrant mixed-use streets located in the city’s higher-density growth areas. They support a wide range of land uses, activities, and are often home to prominent commercial, retail and mixed-use buildings. These streets are often surface transit priority routes in the City’s Official Plan and in the Downtown, and many have busy streetcar routes. Downtown & Centres Main Streets are often routes that lead directly to rapid transit stations. These streets are often lined with taller buildings with wide frontages and active ground-floor uses. Sidewalks are typically adjacent to the curb with existing buildings at or near the street right-of-way. These streets are often supported by a Business Improvement Area. Downtown & Centres Main Streets are typically major streets in the transportation network with a large number of competing demands on available street space, especially on the narrower rights-of-way in the Downtown. They typically connect significant regional and city-wide attractions and destinations and serve a wide variety of different people from across, and even outside the city: residents, workers, shoppers and visitors. 60 26 2.3.2 Street Types Downtown & Centres Main Street DESIGN OBJECTIVES Provide wide sidewalks and boulevards with high-quality pedestrian-scale streetscapes and amenities to encourage walking, lingering, dining and shopping. • Use building setbacks, curb extensions or parklets to expand the space for adequate sidewalks, outdoor seating, cafés patios, plantings, trees and street furnishings. • Prioritize safe movement of pedestrians, cyclists, and surface transit and design for slower but consistent, motor vehicle travel speeds. • Provide frequent and safe opportunities for pedestrians to cross the street, with wide and prominent pavement markings at intersections. Also, explore using curb extensions on side streets to expand the pedestrian realm along the Main Street, shorten crossing distances, and reduce motor vehicle turning speeds. • Toronto Complete Streets Guidelines 2.3.2 Street Types Downtown & Centres Main Street For illustrative purposes - may include a mix of permanent/temporary materials. Provide generous amounts of public bicycle parking that should be coordinated with bicycle parking provided by any adjacent public spaces and buildings. • Support healthy street tree growth on streets where sufficient space exists to achieve required pedestrian clearways and where growing conditions can be optimized. Where space is constrained, consider covered tree pits with Silva Cells and adequate soil volumes to ensure growth. • Consider creative ways to optimize and manage curb-side space for integrating a variety of uses, e.g., parklets, on-street bicycle parking, loading areas, and accessible vehicle boarding. • Provide appropriately located offstreet parking and access such as side streets, parking lots, garages, lanes and parking at the back of buildings to augment parking supply, accommodate loading and minimize driveways, curb cuts and conflicts, especially where space is constrained on the street itself. • Work with local Business Improvement Areas and neighbourhood groups on ways to support placemaking, local economic development, and neighbourhood identity. • To reduce clutter, consider burying overhead utilities if possible or coordinate with other infrastructure, like sharing hydro and streetcar poles, for example. • 61 27 Toronto Complete Streets Guidelines 2.3.3 Straight and direct sidewalk on an Avenue and Neighbourhood Main Street in Etobicoke-York. Avenue and Neighbourhood Main Streets sidewalks often have greening, trees, transit, cafes, sidewalks and more. AVENUE & NEIGHBOURHOOD MAIN STREET Avenue & Neighbourhood Main Streets are vibrant streets that serve as a local focus for Toronto’s many neighbourhoods. These Main Streets typically follow busy surface transit routes with a mix of uses and especially retail at street level. Many of these streets have an Avenue designation in the Official Plan, which means they are important corridors where incremental change, and often growth, is intended to occur. These streets are often lined with mid-rise or low-rise buildings of a more modest scale than the tall buildings found on Downtown & Centres Main Streets. In some parts of the city, the street right-of-way is often wider that those in the Downtown or Centres. Avenue & Neighbourhood Main Streets are important places in the local community, helping support local businesses and services that serve the immediate neighbourhood, but can also attract visitors from outside the area. These streets are often supported by a local Business Improvement Area. These Main Streets typically include cafés, street trees and other plantings as important pedestrian amenities that make the street a vibrant, 62 28 2.3.3 Street Types Avenue & Neighbourhood Main Street comfortable, and appealing place. Sidewalks are typically adjacent to the curb or separated from the roadway by a boulevard, and buildings are sometimes set back from the street to help provide more sidewalk space. Avenue & Neighbourhood Main Streets are major streets in the transportation network for several different travel modes, often all competing for space and prioritization in the street. They are important for the delivery of transit service and for goods delivery to businesses and shops. DESIGN OBJECTIVES Provide wide sidewalk and boulevard space to support high to moderate levels of pedestrian movement. • Encourage people to linger with active ground floor uses, quality pedestrian-scale streetscapes and amenities like greening/trees, benches, parklets and café patios. • Toronto Complete Streets Guidelines 2.3.3 Street Types Avenue & Neighbourhood Main Street For illustrative purposes - may include a mix of permanent/temporary materials. Prioritize safe movement of pedestrians, cyclists and surface transit and design for moderate motor vehicle travel speeds. • Provide frequent and safe opportunities for pedestrians to cross the streets. Also explore using curb extensions on side streets to expand the pedestrian realm along the Main Street, shorten crossing distances, and reduce motor vehicle turning speeds. • Provide adequate and safe bicycle facilities and generous bicycle parking to encourage cycling trips. • Locate vehicle driveways, goods deliveries and loading on side streets or rear lanes where possible to minimize curb cuts and areas of conflict along the street. On some Main Streets, on-street parking can be provided, but look for suitable replacement parking at off-street locations to minimize on-street conflicts. • Work with local Business Improvement Areas and neighbourhood groups to help emphasize neighbourhood identity. • Support healthy street tree growth with open tree pits and planters on streets where sufficient space exists to achieve pedestrian clearway requirements. Where space is constrained, consider covered tree pits. • To reduce clutter and visual impacts, consider burying utilities if possible or coordinate with other infrastructure, and in consultation with the BIA. • 63 29 Toronto Complete Streets Guidelines 2.3.4 New buildings are often set back on Downtown and Centres Residential Streets to provide adequate sidewalk and amenity space. DOWNTOWN & CENTRES RESIDENTIAL STREET These streets are found in the Downtown and Centres and support primarily higher-density residential neighbourhood uses, with taller buildings and higher levels of pedestrian activity than the other residential streets. Buildings on these streets typically range from mid-rise to tall – either independently or as part of a larger building complex – and are sometimes set back a small distance from the street right-of-way, with tree plantings or landscaping. Ground level retail, office, grade related apartments or amenities are sometimes located within the base of the buildings. Downtown and Centres Residential Streets are important links in the city’s transportation network, with high levels of pedestrian and cycling activity and moderate levels of vehicular traffic. Downtown and Centres Residential Streets often have wider sidewalks than other residential streets due to the volume of pedestrians they carry. 64 30 2.3.4 Street Types Downtown and Centres Residential Street There are typically little to no transit services provided on these streets, although significant transit services are usually found close by. Sidewalks are often located next to the curb, though ideally separated by a buffer from moving traffic. Downtown and Centres Residential Streets have a moderate number of competing demands on available street space, especially on the narrower rights-of-way in the Downtown. Toronto Complete Streets Guidelines 2.3.4 Street Types Downtown and Centres Residential Street For illustrative purposes. Provide ample bicycle parking for visitors and residents to encourage cycling. • Plant street trees in the frontage zone if boulevard space is limited. • Manage speed by rightsizing lanes and corners, and providing chicanes, mid-block crossings and on-street parking. • DESIGN OBJECTIVES • Accommodate a high level of pedestrian activity with wide sidewalks. New buildings should be set back to create sidewalk and amenity space. • Prioritize the safe movement of pedestrians and cyclists and design for modest motor vehicle volumes and speeds. Provide driveways and servicing through shared access lanes and on side streets to minimize conflicts on busy residential streets. • On-street vehicle parking may sometimes be provided on at least one side of the street. • Minimize freight transport that is not servicing local properties. • 65 31 Toronto Complete Streets Guidelines 2.3.5 Apartment Neighbourhood Residential Streets have sidewalks that connect to buildings. Example of an Apartment Neighbourhood Residential Streets with a bike parking shelter. APARTMENT NEIGHBOURHOOD RESIDENTIAL STREET Apartment Neighbourhood Residential Streets are found throughout the city and are typically lined with a range of residential buildings: townhouses, walkups, mid-rise buildings, and tall buildings. Traditional Apartment Neighbourhood streets have a range of scales of apartments with shallow front yards and entrances organized like a house. Mid-century ‘tower-inthe-park’ apartment complexes, found in all parts of the city, have large lots with few public streets and large buildings placed in the middle of the lot. They are typically set back from the front property line and landscaped. Street frontages on larger lots include auto drop-offs and parking entrances and may have private short term parking. Apartment Neighbourhood Residential Streets may sometimes play a major role in the city-wide transportation network, especially where they act as key transit routes. Because of their higher density, they often have higher levels of pedestrian use than on Neighbourhood Streets. 66 32 2.3.5 Street Types Apartment Neighbourhood Residential Street Apartment Neighbourhood Residential Streets are typically located on or near transit and many trips are accomplished by walking, cycling or taking transit. Moderate levels of vehicular traffic are typical, and some may have surface transit routes present. Some Apartment Neighbourhood Residential Streets are strong candidates to introduce stormwater management features. This is because Apartment Neighbourhood Residential Streets typically have available space due to large building setbacks, few driveways and low on-street parking demand. Toronto Complete Streets Guidelines Street Types Apartment Neighbourhood Residential Street 2.3.5 For illustrative purposes. Adequate bicycle parking should be provided outside residential buildings to supplement bicycle parking provided inside buildings. • Maintain low motor vehicle speeds to help ensure the street is safe for everyone, and inviting for novice bicyclists and more vulnerable pedestrians. Consider complete streets elements, such as mid-block curb extensions or chicanes to reduce speeds. • DESIGN OBJECTIVES • Provide wide sidewalks that connect buildings to the pedestrian network to support a high level of pedestrian activity. • Promote socializing, interaction and activities along the street, including community events, such as street parties, yard sales, or children playing. • Enhance safety and comfort of transit waiting areas, and transit operations priority where transit service is provided. Provide green space such as a continuous canopy of trees, and stormwater management in curb extensions. • Minimize conflict between motor vehicles and cyclists and pedestrians, especially at driveways and vehicular drop-off areas in front of buildings. • Include lighting that illuminates street and sidewalk but prevents light pollution into the sky and adjacent residences. • 67 33 Toronto Complete Streets Guidelines 2.3.6 Neighbourhood Residential Streets sidewalks often have parents walking with children to school. NEIGHBOURHOOD RESIDENTIAL STREET Neighbourhood Residential Streets are found throughout Toronto in areas designated as ‘Neighbourhoods’ in the City’s Official Plan, which are generally considered as physically stable areas. A range of building types under four storeys in height are permitted in Neighbourhoods, including single family residential and multi-family residential properties. Neighbourhood Residential Streets provide access for buildings and usually provide people with direct pedestrian access to their front door. These streets provide the setting for a range of local neighbourhood gatherings and informal interactions, such as yard sales, festivals and block parties. They are streets where children often play after school or on weekends. They primarily serve local movement needs and have relatively low volumes of motor vehicle traffic. Pedestrian and cyclist safety is a high priority. Transit service is less often provided on this type of street. All Neighbourhood Residential Streets should have sidewalks. Neighbourhood Residential Streets commonly have multiple users, trees, and low vehicle speeds. 68 34 2.3.6 Street Types Neighbourhood Residential Street Neighbourhood Residential Streets are not intended to play a major role in serving city-wide traffic movement. Neighbourhood Residential Streets have potential to introduce pedestrian improvements, such as intersection curb extensions, as well as greening, landscaping, and stormwater management features. There are generally two different subtypes of Neighbourhood Residential Streets in Toronto, distinguished by the era they were originally planned or developed: pre-1950s construction and post-1950s construction (see pages 36 and 37). Toronto Complete Streets Guidelines 2.3.6 Street Types Neighbourhood Residential Street For illustrative purposes. Promote social and community interaction and activities, both across and along the street, including accommodating community events, such as street parties, yard sales, or children playing. • Maintain low motor vehicle speeds to help ensure street is safe for everyone, and inviting for novice bicyclists and more vulnerable pedestrians. • Accommodate neighbourhood vehicle access and circulation needs while deterring through traffic. • DESIGN OBJECTIVES • Emphasize safety and connectivity for pedestrians and cyclists of all ages and abilities. • Provide green space and landscaping and promote a robust canopy of trees. Consider the opportunity to manage stormwater at source as much as possible to reduce stress on sewers and promote natural water infiltration. Provide driveway access to private properties, accommodating curb cuts as necessary, but design to prioritize pedestrians where driveways meet the sidewalk and street. • Provide connectivity to local destinations particularly for pedestrian access. • Include lighting that illuminates street and sidewalk but prevents light pollution into the sky and adjacent residences. • 69 35 Toronto Complete Streets Guidelines 2.3.6 Street Types Sub-type: Neighbourhood Residential Street (built circa pre-1950s) SUB-TYPE: NEIGHBOURHOOD RESIDENTIAL STREET (BUILT CIRCA PRE-1950 s ) For illustrative purposes. These Neighbourhood Residential Streets were typically built prior to 1950, in the period before the automobile became a primary consideration in neighbourhood planning and street design. These neighbourhood streets are usually arranged in a grid pattern, typically with right-of-way widths of 20m or less. Neighbourhood Residential Streets built before 1950 typically have sidewalks against the curb. Neighbourhood Residential Streets may include features to encourage pedestrians and cyclists by reducing vehicles speeds and volumes. Sidewalks are typically on both sides of the street, usually located next to the curb, with a boulevard between the sidewalk and property line. There is sometimes a planting zone between the sidewalk and the curb. These streets tend to have shallow building setbacks and porches at or near the property line. Driveways and curb cuts are uncommon on pre-1950s Neighbourhood Residential Streets, and motor vehicle access and parking is sometimes accommodated through rear lanes. On-street parking is often permitted and some streets 70 36 have also allowed curb cuts for front yard parking. These streets are often one-way for motor vehicle traffic and have narrower pavement widths. Some of these streets also have traffic calming and diversions. There exists a moderate opportunity for implementing green infrastructure. ADDITIONAL DESIGN OBJECTIVES • Trees or landscaping should be provided between the sidewalk and buildings. • Allow for on-street parking on at least one side of the street where space permits. • Consider designated routes for cyclists of all ages and abilities. • Front-yard parking pads are discouraged to reduce impermeable surfaces and to provide parking on-street. • Avoid unnecessarily widening the street in reconstructions. Toronto Complete Streets Guidelines 2.3.6 Street Types Sub-type: Neighbourhoods Residential Street (built circa post-1950’s) SUB-TYPE: NEIGHBOURHOODS RESIDENTIAL STREET (BUILT CIRCA POST-1950 s ) For illustrative purposes. Primarily planned and constructed during or after the 1950s, these Neighbourhood Residential Streets were designed mainly to facilitate car movement, but based on principles that discouraged through traffic. c: Brandon Quigley Neighbourhood Residential Streets built after 1950 typically have buildings set back from the street and landscape strips between the curb and sidewalk. Curb extensions may including landscaping or green infrastructure on Neighbourhood Residential Streets. They were often designed to promote local walking and cycling toward the centre of a neighbourhood, where parks and schools were located. Cul-de-sacs, loop crescents, and a curvilinear street network were created instead of the traditional grid-style street network present in pre-1950s Toronto. Typically, the post-1950’s Neighbourhood Residential Street includes buildings that are set farther back from the property line and have driveways with curb cuts. Long-term curbside parking is usually not permitted and rear lanes are rare. Sidewalks are often separated from the curb by grass or treed areas, but sometimes there are no sidewalks at all. A significant opportunity for green infrastructure exists in this type of Neighbourhood Residential Street. ADDITIONAL DESIGN OBJECTIVES • Rightsize the street through on-street parking, and curb extensions or chicanes. • Provide a sidewalk on at least one side of the street for universal accessibility and pedestrian safety. • Integrate streetscapes with landscaping through setbacks and open space. • Integrate stormwater control measures to improve the natural and aesthetic environment. 71 37 Toronto Complete Streets Guidelines 2.3.7 Some Mixed-Use Connector Streets have trees in a median. Pedestrians and transit are common on Mixed Use Connector Streets. 38 2.3.7 Street Types Mixed Use Connector Street MIXED-USE CONNECTOR STREET Mixed Use Connector Streets are found throughout the city, but more often outside of the downtown and central neighbourhoods. These streets are often longer and more continuous, providing direct travel routes for people and goods that span and connect several neighbouring communities and areas. These streets typically have a mix of different land uses and building types along them with a variety of physical configurations and relationships with the street: sometimes buildings are located further away from the street with landscaping or a parking lot in between, while other times buildings are much closer, with their front entrances at the street. Mixed-Use Connectors play a significant role in the City’s transportation network. They are important travel routes for all modes, but often have higher volumes of motor vehicles and lower volumes of pedestrians and cyclists. Given the higher motor vehicle speeds and volumes, separated bicycle facilities are recommended. These streets also often have important city-wide transit routes and should be designed to give transit priority, where applicable. They are also usually important streets for moving goods. While Mixed Use Connectors play a role in enabling longer-distance travel and movement 72in the city, it is important that these streets be gradually and incrementally improved to help create a more safe and inviting street for people walking and cycling. These streets are often found in areas of the city with longer distances between signalized intersections and higher motor vehicle speeds, so additional care is needed to ensure streets and intersections are designed to be safe for the most vulnerable people walking and cycling. While efficient motor vehicle travel is a priority on these streets, ensuring safety for people walking is critical, with sidewalks sized for a medium volume of pedestrians and intersections designed with clear and well-marked crossing features. Wide landscape strips with trees should be provided on boulevards, as well as transit shelters and other street furniture at stops. Buildings should be set back to enhance street character and increase comfort for pedestrians. These streets are candidates to introduce stormwater control measures in the planting zone Toronto Complete Streets Guidelines Street Types Mixed Use Connector Street 2.3.7 For illustrative purposes. between curb and sidewalk, and where applicable, in the frontage zone. Mixed Use Connectors typically do not have on-street parking. DESIGN OBJECTIVES Emphasize movement between destinations via a variety of modes and support commercial activity. • Provide sidewalks and safe, controlled crossings to connect destinations and especially to transit stops or stations. • Enhance transit amenities (e.g., benches/shelters) and transit operations priority where transit service is provided. • Provide dedicated cycling facilities if part of the cycling network. • Improve safety and visibility at intersections and crossings for pedestrians and cyclists. • Use shared access management to reduce the frequency of access points and conflicts to help manage traffic flow and safety. • Facilitate the efficient movement of • larger volumes of motor vehicle traffic, especially freight and service vehicles. • Include a wide planting zone, especially using frontage zones, to support a continuous tree canopy and to integrate stormwater control measures. 73 39 Toronto Complete Streets Guidelines 2.3.8 RESIDENTIAL CONNECTOR STREET Residential Connector Streets are similar to Mixed Use Connector Streets – their primarily role is to facilitate transportation for all modes – but they provide travel routes and connectivity within and through mainly residential areas of the city. Residential Connectors are typically lined with a variety of residential buildings that face the street, often set back with well-established front yards, gardens, and driveways. Sometimes there are occasional businesses or stretches of rear-facing residential lots and backyard fences along the street. Residential Connector Streets often have a sidewalk between a row of trees and the curb, and sometimes run along the back of properties. Residential Connector Streets may have transit shelters and cycling infrastructure between the curb and buildings. While Residential Connectors play a role in enabling longer-distance travel and movement in the city, it is important that these streets be gradually and incrementally improved to help create a safer and more inviting street for people walking and cycling. Residential Connectors are often found in areas of the city with longer distances between signalized intersections and higher motor vehicle speeds, so additional care is needed to ensure streets and intersections are designed to be safe for the most vulnerable people walking and cycling. Although safe and efficient 74 40 2.3.8 Street Types Residential Connector Street motor vehicle travel is a priority on these streets, safety for people walking is critical, with sidewalks sized for low to medium volumes of pedestrians and intersections designed with clear and well-marked crossing features. Wide landscape strips with trees should be provided on boulevards, as well as transit shelters and other street furniture at stops. Buildings should be set back to enhance street character and increase comfort for pedestrians. Residential Connectors can sometimes have some on-street parking. Residential Connectors are candidates to introduce stormwater control measures in the planting zone between curb and sidewalk, and where applicable, in the frontage zone. Toronto Complete Streets Guidelines Street Types Residential Connector Street 2.3.8 For illustrative purposes. Enhance amenities (e.g., benches/ shelters) and transit operations priority where transit service is present. • Provide dedicated cycling facilities if part of the cycling network. • Include a wide planting zone, especially using the frontage zone, to support a continuous tree canopy and to integrate stormwater control measures. • DESIGN OBJECTIVES • Emphasize movement between destinations via a variety of modes. • Improve safety and visibility at intersections and crossings for pedestrians and cyclists. • Provide sidewalks and safe controlled crossings to connect destinations, especially to transit stops or stations and major neighbourhood destinations. 75 41 Toronto Complete Streets Guidelines 2.3.9 Street Types Scenic Street 2.3.9 SCENIC STREET Scenic Streets are found throughout the city where there is a strong relationship with natural features like ravines and the waterfront, or with significant parks and green spaces. Scenic Streets are primarily characterized by their ‘park-like’ setting and adjacency with nature. Scenic Streets are also often meandering or winding, following the city’s natural topography. c: Kenn Chaplin Scenic Streets often run along parks or natural features. Scenic Streets can play a variety of roles in the transportation network. Demand for walking or cycling is often high, as these streets follow, or are adjacent to, areas of high demands for recreational use. Motor vehicle volumes can be high during peak hours, but much lower at other times of the day. While separating pedestrians and cyclists is always preferred in areas with higher recreational use, shared-use paths may be considered in lieu of Scenic Streets often have separated paths for pedestrians and cyclists. 76 42 sidewalks to separate pedestrians and bicyclists from other traffic. Scenic Streets may also be surface transit routes. There are usually few crossings on these streets but, where present, they must be carefully designed to safely allow connectivity and crossings for recreational path users. There is typically no on-street parking on Scenic Streets. Scenic Streets often have large and healthy trees that together create a substantial canopy. The adjacent open spaces present many opportunities to introduce storm water control measures. Toronto Complete Streets Guidelines 2.3.9 Street Types Scenic Street For illustrative purposes. Provide sidewalk on both sides and separated bicycle facilities on at least one side of the street where appropriate. Ensure adequate space for pedestrians and cyclists with a physical delineator between pedestrians and cyclists for safety and universal accessibility. • Integrate street and boulevard design with adjacent areas such as landscapes. • Design to accommodate both weekday rush hour commuter activity as well as off-peak (e.g. weekend) recreational use. • DESIGN OBJECTIVES • Emphasize and highlight natural landscape character and features. • Preserve and protect scenic views and vistas. • Enhance environmental quality by protecting and enhancing tree canopy and incorporating naturalized stormwater control measures. • Support medium to high volumes of pedestrian and bicycle activity for both recreation and transportation. • Enhance transit operations priority where transit service is provided. 77 43 Toronto Complete Streets Guidelines 2.3.10 Park Streets are often lined with trees and separated walkways. Park Streets should be designed to accommodate different types of pedestrians and cyclists. 2.3.10 Street Types Park Street PARK STREET Park Streets are streets found within, adjacent to, or leading to city parks. They provide local neighbourhood connections and access to park facilities. Park Streets are primarily intended to support and complement parks and recreation uses. These streets typically play a minor transportation role for motor vehicles and transit, but a significant role for pedestrians and cyclists. Street design,landscaping and features should help create an environment that naturally encourages lower vehicle speeds and provides park-like experiences on foot or on a bicycle. Cycling and walking is prevalent, and should be welcomed, prioritized and safe, especially for the most vulnerable. Cyclists may have a separate facility such as a lane or path, but may also mix in the general use of the street. In areas with higher recreational use, cyclists and pedestrians should be separated to improve safety, accessibility and enjoyment. Bus transit may be provided within larger parks during park hours but are generally not high-frequency routes. There is sometimes on-street parking provided. Park Streets within parks are sometimes closed during the evenings with the same hours of access as the park itself, and some may even be gated. 78 44 Given they are in parks, adjacent to, or leading to parks, these streets should have large and healthy trees that together create a substantial canopy to complement and add to the tree canopy in the park itself. These streets present many opportunities to introduce stormwater control measures. Streets adjacent to parks, or that lead to and connect with parks can extend the park amenity and character into the surrounding neighbourhoods, providing improved access to parks for pedestrians, cyclists and wildlife. Toronto Complete Streets Guidelines 2.3.10 Street Types Park Street For illustrative purposes. Enhance and augment existing tree canopy and incorporate naturalized stormwater control measures. • Provide local vehicle access and circulation to parks, and within some parks, and target low vehicle speeds. • Accommodate park service and maintenance vehicle needs. • Provide continuity in the landscape design and streetscape between the public spaces on adjacent streets, and the routes within the park for a connected network. • DESIGN OBJECTIVES • Complement and enhance the park’s environmental and natural qualities. • Provide attractive walking and cycling routes between the park and the local neighbourhoods and between destinations within the park. • Provide facilities for a wide range of cycling skill levels, but provide separate facilities for pedestrians and cyclists in locations of heavy recreational use, often on multi-use trails or sidewalks on at least one side of the street. 79 45 Toronto Complete Streets Guidelines 2.3.11 Street Types Employment Street 2.3.11 EMPLOYMENT STREET c: Michael Poos Employment Streets are typically found outside of the Downtown and support mainly industrial or commercial uses inside Employment Areas or Districts. Buildings usually range from multi-storey commercial offices, to lower-rise wholesale or large-format retail, warehouse, and manufacturing buildings. Buildings are often set back from the property line with parking or landscaping between the building and street. Employment Streets often have driveways and crosswalks to facilitate access. Employment Streets serving warehouse or manufacturing uses often need to accommodate larger trucks turning, as well as loading and unloading activities. Employment Streets dominated by more commercial or retail uses may have less large truck activity. Employment Streets are important links in the goods movement network, but typically of lower importance in the overall city-wide transportation networks. A significant number of users of these streets arrive by car, but this is not the only mode of access. Many who work on Employment Streets rely on transit, walking and cycling. Employment streets should be designed to encourage walking, cycling and transit use, especially where they serve as a link between adjacent neighbourhoods and Main Streets. Employment Streets generally have Employment Streets typically have bus stops to provide mobility options for workers and visitors. 80 46 rights of way that enable the provision of sidewalks on both sides and complete connections in the pedestrian network. Safe pedestrian and bicycle accommodation, especially at intersections where trucks are turning, is essential. Truck traffic may be significant on Employment Streets. Vehicle traffic is generally moderate, but can be substantial during peak hours. Parking on street is usually not desired due to large truck turning radii. Long term bicycle parking, such as sheltered bicycle corrals, should be provided. Some Employment Streets have grassy boulevards with significant tree planting. Many are candidates to improve street tree planting and introduce stormwater control measures in the planting zone between curb and sidewalk (where present).

Mixed Use Access Streets primarily provide ‘rear’ service and access functions to adjacent commercial and residential properties, which often have their front doors on other nearby Main Streets. Mixed Use Access Streets generally have narrower rights-of-way, but are larger than a lane. Mixed-Use Access Streets provide truck loading access for large buildings. Mixed Use Access Streets are typically not major streets in the transportation network. They are usually limited in length and do not support long-distance travel. Driveways, service entrances and loading docks are common on these streets, which introduce conflicts with pedestrians, cyclists and other Mixed-Use Access Streets accommodate pedestrians, delivery on foot, and often have on- or off-street parking. 82 48 2.3.12 vehicles that must be managed. While cars and service vehicles are often the dominant users, these streets should also provide a safe environment for pedestrians and cyclists. Surface transit is very uncommon on Mixed Use Access Streets. Many will have low or moderate pedestrian and cyclist volumes, with low volumes of mostly larger vehicles, like garbage or delivery trucks. Toronto Complete Streets Guidelines Street Types Mixed Use Access Street 2.3.12 For illustrative purposes. Provide an adequate furnishing zone for key elements like light poles, waste/recycling receptacles and bicycle parking, and consider landscaping and street trees where possible. • Some on-street parking may be provided if space is available. • Provide wayfinding signage to assist drivers with finding building access and entrances to loading areas and parking garages. • DESIGN OBJECTIVES • Facilitate deliveries, loading, and service access for adjacent residential and commercial buildings. • Provide access to secondary pedestrian entrances to buildings. • Safely accommodate pedestrians and cyclists, and encourage low motor vehicle speeds. • Consider ways to create an attractive environment that complements adjacent Main or Civic Streets. 83 49 Toronto Complete Streets Guidelines 2.3.13 Seasonal or permanent bike corrals are common on Shared Streets. 2.3.13 Street Types Shared Street MIXED-USE SHARED STREET Shared Streets are most often found in areas supported by a high level of pedestrian activity, usually in mixed-use areas in the Downtowns and Centres but can also be found in residential neighbourhoods. Shared Streets are streets that blend and blur the spaces and zones of the street – sometimes designed without curbs. Different modes share the space together, but pedestrians typically have the highest priority. Shared Streets must maintain a delineated pedestrian clearway zone to ensure the street is universally accessible. The remaining street space is shared between several different modes or users, but pedestrians typically have the highest priority. Shared Streets can have a flexible design to accommodate different uses and seasons. All modes of travel may be permitted on Shared Streets, but motor vehicle volumes and speeds are extremely low. All modes are expected to travel no faster than walking speed. Some Shared Streets may prohibit motor vehicle access and parking entirely, except for emergency, utility, and delivery vehicles during specific times of day, days of week, or entire seasons. Trench drain and bollards on Shared Streets provide for curbless and flexible streets. 84 50 In the Downtown or Centres, buildings are typically more mixeduse and located close to the property line, clearly defining the street edges. Shared Streets can support a variety of uses, including shopping, entertainment, cafés, dining, and residences. Toronto Complete Streets Guidelines 2.3.13 Street Types Shared Street For illustrative purposes. In mixed-use settings, support commercial activity (such as occasional pedestrian-only streets for events/markets) or neighbourhood gathering, recreation and leisure depending on context. • In mixed-use settings, support flexible use of the street right-of-way through all seasons including incorporating café seating in spring/ summer/fall, and short-term parking or drop-off in winter. • In mixed-use settings, accommodate high volumes of pedestrians and/or pedestrian lingering, socializing. • DESIGN OBJECTIVES • Create street conditions for very low motor vehicle volumes and very slow travel speeds to facilitate shared use of the street by pedestrians, cyclists and motor vehicles. • For universal accessibility provide a direct and unobstructed walking path of adequate width, delineated by pavers and/or bollards with adequate contrast and detectability. • Create a slow zone “feel” for the public space using design treatments (e.g., rightsized space, pavers, plantings, street furniture). • In mixed-use settings, prioritize, enable and emphasize pedestrian activities while also accommodating motor vehicle access by service and delivery vehicles during non-peak hours. 85 51 Toronto Complete Streets Guidelines 2.3.14 Residential Shared Streets are typically slow zones that include space for people, trees and parking. Street Types Residential Shared Street RESIDENTIAL SHARED STREET Residential Shared Streets are streets in primarily residential areas that mix all modes together to blend and blur the spaces and zones of the streets. All modes are expected to travel no faster than walking speed. Shared Streets in residential areas provide space for informal neighbourhood gatherings and activities, like socializing and children playing. In residential areas, where they are referred to as ‘woonerfs’ or ‘home zone’ streets, Shared Streets may also permit some on-street parking. Shared Streets are good locations for higher amounts of bicycle parking to help serve the needs of the surrounding area. Shared Streets should be narrow to help slow vehicle traffic and emphasize pedestrian priority. Some Residential Shared Streets, like this one in Toronto, have planters and brick pavers. 86 52 2.3.14 Shared Streets are primarily hardscape, but the low vehicle volumes make them prime candidates for pavers, permeable pavement and other infiltration strategies. Limited plantings and planters soften the environment and provide additional opportunities for greening and stormwater management. Toronto Complete Streets Guidelines Street Types Residential Shared Street 2.3.14 For illustrative purposes.

These lanes support vehicle and pedestrian access to buildings of various uses. They are typically narrow access routes flanked by the rear or side faces of abutting properties. Mixed-Use Lanes provide access for deliveries, waste disposal and pickup, and parking garage entrances, as well as informal local cyclist and pedestrian routes. They help to restrict or minimize driveway access and loading on Civic and Main Streets to support efficient movement of people and to reduce conflicts among modes. Mixed Use Lanes are typically significantly narrower than Mixed Use Access Streets and much shorter – commonly just one block long. Mixed-Use Lanes are very minor links in the overall transportation network. Although their primary role is for motor vehicle service and access, these lanes are often used as quieter, informal routes for pedestrians and bicyclists. Laneways in Toronto provide space for murals, and pedestrian and/or vehicle access to properties. 88 54 In a busy Downtown environment, Mixed-Use Lanes can also offer unique opportunities to create active spaces for retail or other commercial users, and become part of a vibrant pedestrian network. Although space for tree planting is limited, and some servicing requirements can present challenges, Mixed-Use Lanes do provide some opportunities to introduce stormwater control measures. Toronto Complete Streets Guidelines 2.3.15 Street Types Mixed Use Lane For illustrative purposes. Anticipate and accommodate through-access by pedestrians and cyclists and use of lanes as informal public spaces. • Durable street materials for heavier vehicles, like garbage and delivery trucks. • Provide adequate lighting for personal security. • DESIGN OBJECTIVES • Support adjacent commercial and residential uses by providing access to the rear of buildings for service, delivery, loading, and parking garage access needs. • Minimize cut-through motor vehicle traffic and design for slow vehicle speeds. 89 55 Toronto Complete Streets Guidelines 2.3.16 2.3.16 Street Types Residential Lane RESIDENTIAL LANE Residential Lanes are found throughout the city and typically provide rear access for pedestrians and vehicles to garages, parking, and rear entrances of single family homes and low-rise residential buildings. They are often narrow access routes flanked by fences or garages at the rear of properties. Residential Lanes have the opportunity to become attractive public spaces that support informal play and social interaction. Residential Lanes are often used by pedestrians and cyclists. Motor vehicle volumes are low and slow on residential lanes, and they do not play a large role in the overall transportation network. They are often used for pedestrian and bicycle connections within the neighbourhood, and should be designed for walking speed to emphasize and encourage pedestrian use. They are often used for local recreational activities. Residential Lanes typically provide garage and vehicle parking access at the rear of properties. 90 56 Although space for tree planting is limited, Residential Lanes do provide opportunities to introduce green street design elements and planting to create more inviting and useful spaces. Toronto Complete Streets Guidelines 2.3.16 Street Types Residential Lane For illustrative purposes. Minimize cut-through motor vehicle traffic, enhance local access, and design to slow motor vehicle speeds. • Anticipate and accommodate through-access by pedestrians and cyclists. • Provide adequate lighting for personal security. • DESIGN OBJECTIVES • Provide access to rear of residential properties and encourage informal spaces for playing and social interaction through speed management (e.g., rightsizing of space). • By providing the residential lane, this reduces or removes the need for driveways and motor vehiclepedestrian conflicts from the parallel residential street. 91 57 B.2 Common Street Design Terms Here we define a few general terms and concepts that will be used throughout the remainder of this section. A curb extension is where the curb extends out and expands the sidewalk beyond the typical curb alignment. Curb extensions can also be on either side of on-street parking, and provide additional space for features such as benches, trees and plantings, surface transit stops, and bike racks. Curb radii refers to the curved section of a curb that connects two intersecting streets. Medians or raised islands separate lanes or directions of traffic within the roadway using pavement markings or raised concrete islands. Rightsizing involves redesigning the physical space and using geometric design to improve safety conditions for everyone using the street. The purpose of traffic calming devices such as speed bumps or diverters is to alter drivers’ behaviour and to improve road safety. Transit queue-jump lanes are typically extended right turn lanes that provide opportunities for buses to move to the front of the queue. B.3 Street Design for Pedestrians B.3.1 Sidewalk Design and Streetscaping The most comfortable and functional sidewalks have five zones that vary according to the street’s land uses and pedestrian volumes: frontage, throughway, furnishing, edge, and extension zones. These are visualised in Figure 16 and discussed below. • Frontage zone: On residential streets where buildings are near the street, frontage zones may be wider to accommodate front stoops and waiting areas at front doors. Street furnishings can be located in the frontage zone on sidewalks that are too narrow to accommodate a large furnishings zone in order to keep the throughway zone clear for pedestrians and wheelchair users. • Throughway zone: The throughway zone is the area of sidewalk that is free and clear of any obstacles so that people of all ages and abilities can travel in a direct, continuous path. At minimum, two assistive devices (e.g. strollers, wheelchairs, walkers) need to be able to pass each other with a buffer. This minimum space (2.1 m) provides a safe, universally accessible path for people of all abilities. Issues with lack of space include having to pass on uneven surfaces (like sod) that could tip a wheelchair, or being blocked on one side by a wall and not having space to pass. This minimum space can be widened to allow for higher volumes of pedestrians near frequent transit nodes and other important destinations. When measuring the throughway, do not count the space right up to a bench, bicycle post/ring, or other element (e.g. door opening areas, frontage and marketing 92 Figure 16: The five zones of the sidewalk each have a role to play in designing streets for people. areas or tree pits) as you must account for how it’s being used. Think of the users or objects taking up space, such as someone sitting on a bench (with their legs/feet on the throughway), a bicycle locked to a post/ring, or someone standing or lining up for a transit stop or food vendor. • Furnishing (and planting) zone: Use street trees and landscaping to create a visual buffer between the roadway and the sidewalk, providing a sense of enclosure and comfort for pedestrians. A furnishing zone of at least 1.5 m will provide pedestrians with a comfortable buffer from traffic. Where transit shelters are required, a more generous furnishing zone may be necessary. To help maintain pedestrian comfort when vehicle speeds on the adjacent street exceed 40 km/h, widen the furnishing zone beyond 1.5 m. Treat the furnishing zone with a surface material different from the throughway zone, where appropriate, to help identify it as a place for lingering outside of the pedestrian path of travel. The furnishing zone can also be treated as a planting zone or bioswale to enhance the streetscape and improve stormwater management. Street furniture should be placed and arranged with children and the elderly in mind, as they may require more frequent rest stops as well as furniture that is easily accessible. Trees are also useful for vulnerable populations as they provide a shade canopy. Space street trees consistently at 6 m to 9 m intervals, and consider appropriate clearances from utility boxes and street lights. Use tree grates along areas with high pedestrian activity to protect street trees and reduce safety hazards. Select plant species that, when mature, are of an appropriate scale to the site. For example, to lower the apparent height of a tall building, tree species that will grow tall can be effective in reducing the apparent or perceived height of the building at grade. Alternatively, to frame a wide street, tree species should be large/wide and of sufficient massing to create a sense of enclosure. Trees at the street edge should generally be deciduous or palm (i.e., not coniferous). • Edge zone: An edge zone of at least 1 m on streets with parallel parking will ensure that motorists entering or exiting a vehicle don’t impede pedestrians or interfere with landscaping or utilities 93 in the furnishing zone. Design the edge zone on commercial streets to accommodate curbside freight loading. • Extension zone: Extension zones can widen the usable pedestrian space at mid-block and corners and can accommodate additional amenities such as bus shelters and other pedestrian features. Use curb extensions to consolidate elements typically found in the furnishings zone, where appropriate, to allow for a wider throughway zone. Where applicable, extend bus or pedestrian curb extensions the full width of the parking lane. B.3.2 Additional Accessibility and Universal Design Features Tactile walking surface indicators (TWSIs) are flat-topped bumps detectable under foot, used as warning or attention indicators for people with low or no vision. These are installed at intersections, curb ramps, transit platform edges, and depressed curbs where a pedestrian may encounter moving vehicles. A tactile, colour contrasting, and/or physical delineator is required between the sidewalk and sidewalk-level cycle track, or for a flush street where pedestrians are at the same level or grade as cyclists and cars. Tactile strips must also be used at transit stop areas. The design and layout of TWSIs depends on the context, i.e. speed and volumes. B.3.3 Public Realm and Placemaking: Design Great Public Spaces Placemaking is the act of creating public spaces that contribute to the location’s unique character. Highquality public spaces can take on many different forms: from small, intimate spaces between buildings, to niches or steps that allow pedestrians to pause along a busy commercial corridor, to larger open plazas that can accommodate public gatherings and events and have convenient access to public transit. Seek ways to enhance and support the unique character of a street, e.g., social and cultural aspects of the location, such as designing public spaces for lingering and respite, not just movement. For example, curb extensions on side streets enable seating and plantings to enhance local character. Street furniture, pedestrian-scale lighting, and public art will also contribute to the identity of a street. Look at strategies that include use of building setbacks and/or re-purposing underutilised roadway space for placemaking objectives for a street’s context. The creation of seat walls, steps, and planters that can serve as informal seating areas is encouraged as a means of expanding the seating potential and providing diverse opportunities for social interaction. Provide formal and informal seating wherever possible to increase the number of opportunities for people to socialise and spend leisure time outdoors along streets. Provide seating along walkways and at key scenic viewing locations. Use double rows of trees in key areas, such as adjacent to parks or along/within a segment of the centres and corridors to highlight a landmark building or significant view. Use tree grates along areas with high pedestrian activity to protect street trees and reduce safety hazards. Select plant species that, when mature, are of an appropriate scale to the site. 94 Design the public realm to contend with rain and other inclement weather. Pedestrians, particularly those travelling to and from or waiting for transit, must be offered adequate shelter from inclement weather to promote the use of transit services. Use treatments such as awnings, arcades, and galleries to protect pedestrians from the weather and to add visual interest to the streetscape. Pursue continuous weather protection on streets with high volumes of pedestrians, especially on key pedestrian routes to transit stations and exchanges. Use clear or translucent materials for building overhangs, where appropriate, to provide shelter while still maintaining natural light on the sidewalk. Ensure that shelter size and placement are sufficient to accommodate projected volumes of waiting transit passengers without impeding pedestrian movement. Locating parks, plazas, and visually appealing sites along pedestrian routes and sidewalks will increase their usage and promote walking as a form of transport, in addition to promoting transit use by making walking an attractive option (since part of taking transit is walking to/from transit stops). Different types of parks and plazas, along with their design approaches and guidelines, are discussed in depth in Appendix J. B.3.4 Parking and the Pedestrian Realm Surface parking in high-density areas along commercial and mixed-use corridors can be reduced by placing parking underground, behind buildings, or in above-ground parking structures that are designed with architectural screening or that are wrapped with retail uses to animate the pedestrian realm. This approach will create a continuous street edge that is visually pleasing and that promotes interaction between the public and private realms. Similarly, if designed properly, on-street parking can actually enhance the pedestrian experience by serving as a buffer between sidewalks and vehicle travel lanes. Provide shared parking facilities for uses that have peak demands at different times of the day and week, thereby minimising the number of parking structures and reducing their impact on the urban form. Ensure that on-street parking doesn’t block cyclist, pedestrian, and car sightlines, and does not interfere with transit operations. Place off-street parking out of sight from the street – below grade or to the rear of the building – to maintain a continuous edge between the public, semi-public, and private realms of the streetscape, and to provide direct pedestrian access to buildings. Wrap multi-storey parking in active retail or commercial uses to screen parking from the street and to increase street-level activity. Orient parking garage access points toward side streets or alleys to reduce the potential for conflict between cars and pedestrians on busy streets. Where larger areas of surface parking exist, introduce a street and block pattern within parking lots to enhance pedestrian access and enable the introduction of streetscape treatments. Appendix L provides excellent parking lot guidelines, as well as many great design ideas. B.3.5 Safety of the Pedestrian Public Good design can help to enhance safety and security through the principles of natural surveillance and territorial reinforcement. Orient buildings and windows toward streets, plazas, station areas, parking lots, and other public spaces, and maximise the use of ground-floor retail to bring activity to street 95 level. Maintain adequate sightlines with transparent materials in key design features such as fences. Use benches, seating, plazas, or other amenities to attract people and establish public ownership of public and semi-private spaces. Street lighting supports safety, pedestrian activity, sense of place, and economic vitality. Place lighting to illuminate points on the street where there is a high potential for conflict, such as driveways and intersections. Pedestrian-scale lighting for sidewalks and crosswalks ensures that pedestrians are visible to motorists and illuminates potential tripping hazards. Where cycling facilities are located adjacent to the sidewalk, these benefits are also extended to cyclists. Orient lighting to maximise lighting efficiency and eliminate blind spots or dead zones. Avoid lighting that is too bright or out of character with the rest of an area, as it can undermine natural surveillance through excess glare. For more information on creating safe environments via effective lighting while reducing light pollution, see Appendix K. Since pedestrians are given the highest priority in the throughway zone, street furniture, outdoor cafés, and marketing displays must not obstruct or infringe on the pedestrian throughway. Instead, locate these in the Furnishing and Planting Zone or Edge Zone (for narrower elements), or on private property using building setbacks and easements. B.3.6 Child Mobility Design safe mobility networks to encourage children’s independence and active transportation. The ability of children to move independently through their neighbourhood fosters social and physical development and provides opportunities for play. Children are granted increasing independence when caregivers perceive a sense of safety and security in the public realm. Children move differently and less predictably through the public realm than adults, and thus require some unique design considerations. Schools are one of the most important daily destinations in a child’s routine, and active transportation becomes a viable option when schools are within a convenient walking distance from home. A safe route is the primary route through a neighbourhood that connects child-specific destinations. Safe routes are ideally located on local streets. These help mitigate real and/or perceived risk associated with independent mobility. Safe routes should be designed by: • Identifying routes between existing child-focused destinations such as schools, community centres, libraries, parks, and playgrounds; • Locating new child-focused destinations on safe routes; • Congregating child-focused destinations to minimise the number of intersections children need to cross; and • Using signage to indicate the presence of children, as well as signage legible to children to allow for their way-finding. Signage should be located so that it’s visible at a child’s height and include colourful symbols. 96 Consider reduced speed limits on safe routes that include child-focused destinations along their length. Pedestrian infrastructure should be wider, where possible, on safe routes to school for children under 14 who can legally ride bikes on the sidewalk, It should also incorporate ramps on public stairs for stroller or bicycle wheels, to improve access and connectivity. When cycling infrastructure is provided, it should connect to safe routes, to the network of child-focused destinations, and be physically separated from vehicular lanes and parking to minimise risks and provide comfort for children. B.4 Street Design for Cycling B.4.1 Key Cycling Elements When evaluating the potential of cycling infrastructure, routes, and facilities, consider the following points visualised in Figure 17: • Current and potential demand: Number of existing and potential cycling trips. Number of short trips by motorists (less than 5 km) with a high potential to shift to cycling. Areas where cycling volumes have high growth. • Population and employment density: Greater density or new developments suggests more cycling trips. • Network coverage, connectivity, and barrier crossings: The presence of gaps in the network, or barriers (e.g. ravines, rail corridors), that a route could help overcome. While few passengers will walk more than 800 m to reach transit, cyclists might travel up to 5 km (usually, 2.5 km) to reach high-frequency transit services. • Trip generators and target demographics: Assess whether the cycling project would improve access to popular destinations, such as schools, universities, and transit stations. Also look at how well the cycling project would meet the needs of target demographics such as women commuting, tourists, and children getting to school. • Safety: Opportunities to improve cycling safety if the street in question is higher speed, known to have a high number of collisions, or reported traffic safety issues. B.4.2 Cycling Lane Infrastructure Design Principles High-quality cycling facilities are attractive and people will go out of their way to use designated routes with specialised infrastructure. The following are principles to apply when designing roads with bike lanes and infrastructure: 1. Context-appropriate designs. Faster, busier streets create more risk for cyclists and will need greater separation and protection for cyclists as shown in Figure 19. Quiet streets with low traffic volumes and low speeds may provide a comfortable cycling experience without a dedicated cycling facility. For more information, see subsubsection B.4.4. 97 Figure 17: Considerations for Cycling Impact Analysis. 2. Design for both present and future users. Cycling ridership numbers will grow if a cycling facility is provided on a street that was previously uncomfortable for cycling. Where cyclist volumes are growing or predicted to grow, consider widening the cycling facilities. 3. Prioritise the most vulnerable road users. Vulnerable users such as children or the elderly can be seriously injured or killed in even minor collisions. Think of how to design facilities for all types of cyclists, as well as the protection of pedestrians of all ages and abilities. Protect pedestrians from cyclists by providing cycling facilities that are separated from sidewalks using design treatments that respond to both pedestrian and cycling speeds and volumes. Treatments range from buffers and physical delineators to visual contrast and TWSIs. 4. Visible, intuitive cycling facilities. Clear delineation of the cycling path of travel and wayfinding can improve safety for all road users. Use in-road markings to show cyclists where to position themselves on a street with shared lanes and to indicate to drivers that cyclists will be present. To increase motorist awareness and cyclist safety, use solid-coloured pavement (such as green) to demarcate bike lanes. Use pavement markings, signs, grade change between users, and physical design (like buffers) to mitigate hazards such as car doors opening, or pedestrians walking into bike paths. 5. Intersection safety and mixing zones. Continue bike lane markings through intersections and pedestrian crossing markings over cycling routes, and clearly mark conflict areas. Consider providing visible, designated space for cyclists to wait and make turns. Avoid pedestrian and cyclist mixing zones, especially at intersections with high pedestrian volumes. Provide traffic signals where off-street bike paths cross major roads. 6. Adequate bicycle parking. Support and encourage cycling through a convenient and adequate supply of bicycle parking, including multi-unit parking stations especially in mixed-use, institutional, and commercial areas. For more information, see subsubsection B.4.5. 7. Cycling infrastructure frequency. Cyclists are only likely to detour up to 400 m beyond the shortest route to their destination to use designated bicycle facilities; therefore, bike networks 98 Figure 18: Different types of cycling infrastructure. should ensure that facilities are spaced a minimum of every 500 m in areas where increasing cycling is an objective. 8. Cyclist visibility. Where angled parking is provided adjacent to bike lanes, use back-in angled parking to improve visibility and reduce the risk of collisions. Also, handlebars are typically at a height of 1.1 m with eye level at 1.5 m when seated on a bike, so keep this in mind when designing bike lanes to ensure visibility. B.4.3 Bike Lane Widths In general, bikes physically take up 0.75 m width of space, so a comfortable minimum bike lane size would be 1.8 m — enough for one bike to pass another bike with a buffer between them. An ideal width for one-way lanes on roads is 2 m, especially on streets with steep grades or high volumes of cyclists. At pinch points or constrained intersections, provide at least 1.5 m for a one-way lane. At a minimum, no bike lane width should be less than 1.35 m. Off-street paths should be at least 3 m wide so that two cyclists can ride comfortably together and pass another cyclist. Where high volumes of pedestrians and cyclists are expected, providing separate lanes for cyclists and pedestrians increases the safety of all users. B.4.4 Context-Sensitive Cycling Facilities As shown in Figure 18, different types of infrastructure exist for bike lanes depending on the local context. Higher road volumes and speeds mean higher risk, which necessitates increased separation and protection as shown in Figure 19. Examples include painted and buffered bike lanes, cycle tracks (separated bike lanes with bollards, planters, or a row of parked cars between cyclists and moving traffic), and raised cycling facilities (e.g., curb protecting cyclists from cars, cycling facility in the boulevard, etc.). In these cycling facilities, motor vehicles aren’t allowed to drive, stop, stand, or park. Exceptions may be made for transit pick-up and drop-off. Low road volumes and speeds may provide a comfortable cycling experience without a formal cycling facility (e.g. by instead using sharrows or shared lanes). Some quiet streets that are part of the cycling network may have dedicated facilities, or a range of design features including traffic calming measures, 99 Figure 19: The relationship of traffic speed and volume to types of cycling facilities. shared lane pavement markings, and wayfinding.15 These may also include wider curb lane widths, provisions exempting bikes from some traffic regulations, maintaining cycling access through traffic calming infrastructure, and bicycle signals. B.4.5 Bicycle Parking Many types of bicycle parking facilities exist, from ring-and-post to bicycle parking structures such as secure bicycle stations or bike lockers. Bicycle parking in the right-of-way should be considered on every street type, except perhaps some Neighbourhood Residential Streets and Laneways. It’s especially important on Main Streets and near destinations, such as in institutional, mixed-use, and commercial areas. Bicycle parking, including the parked bicycles, must not obstruct the pedestrian throughway. Also consider the space needed to access bikes while being locked or unlocked. B.5 Street Design for Transit B.5.1 Key Transit Street Elements Transit lanes, transit stops, and intersection treatments are the three types of transit facilities that should be considered for complete street improvements. They may be considered on their own, but should be combined while considering their benefits and impacts on all road users in the street design process. Dedicated transit lanes are typically used to move the highest volume of passengers and to support the highest frequency of transit vehicles. They are marked for transit only using pavement markings, signs, and sometimes physical design. Reserved lanes allow any combination of transit vehicles, taxis, and bicycles.16 Reserved lanes can allow for greater transit frequency and reliability on routes with high ridership and congestion. Shared-use lanes, where transit moves together with mixed traffic, are useful alternatives in many places where right-of-way space is limited. Transit service can be improved on shared-use lanes through geometric design, signal timing, and parking and turn restrictions. 15 16 Bicycle wayfinding consists primarily of signs and pavement markings legible to cyclists while travelling. Note that shared bike/bus lanes force buses to go at the speed of bicycles if any bikes are ahead of that bus. As of August 2017, no method exists to intelligently separate the two while maintaining a “shared” reserved lane. 100 Intersection treatments are extremely important for all road users, and are thus discussed in-depth in subsection B.9. B.5.2 Transit Stops The location and design of transit stops has direct implications for the comfort and convenience of transit passengers and other users. The selection of stop locations is generally guided by the safety and comfort of transit users, and minimising transit delay. Key considerations for locating stops include spacing between stops, as well as stop location relative to intersections and land uses, including intensifying areas. The spacing between stops should be between 300 m to 400 m in most locations to balance access to transit with travel time for passengers, though this may vary based on context. Generally, stops should be located at intersections. Stops should be clear of clutter and unobstructed for boarding and alighting. Signalised intersections are ideal locations to allow for safe pedestrian crossings, and increase the likelihood of route-transfers. Mid-block bus stops are recommended only near significant pedestrian generators, where intersections are far away, and should be located next to controlled crossings for easy access. Key considerations for transit stop design include: • Safety: visibility, lighting, geometry, and reducing conflicts. • Accessibility: TWSIs, sign poles, curb cuts. • Comfort: protection from weather, coordinated street furniture for waiting passengers, and facilitating transfers with transit information. • Placemaking: as gateways to streets and neighbourhoods, stops should be legible and provide users with wayfinding information. • Integration with transit vehicle design: the number, type, and size of vehicles that will use the stop affects the size of a stop and landing pads. B.5.3 Transit Design Principles The following are principles to apply when designing roads with bus lanes and infrastructure: 1. Enhance transit users’ experience. Enhance the reliability, frequency, and speed for transit by prioritising space for transit and by implementing signal priority. Consider ways to improve convenience and comfort for users through amenities such as transit shelters, bus stop landing pads, tram platforms, street furniture, lighting, greening, public art, and real-time travel and route information. 2. Make connections safe, convenient, and seamless. Facilitate ease of transfers among different transit routes, walking, cycling, and other modes of transportation, such as sidewalks and crossings to transit stops, bicycle parking, and wayfinding information. While few passengers will walk more than 800 m to reach transit, cyclists might travel up to 5 km (usually, 2.5 km) to reach high-frequency transit services. 101 3. Visible, safe, and convenient transit stops. The location of bus stops should take into account the location of pedestrian crossings and seek to minimise crossing distances between transit connections. Stops should be located at signalised intersections, or at controlled crossings, as it allows for safe access to stops or when making route transfers. Locate stops near pedestrian generators. 4. Universally accessible transit stops and facilities. Design for all users with universal accessibility, comfort, and mobility of passengers in mind, such as accessible transit shelters that accommodate the pedestrian throughway, curb ramps for new LRT stops, TWSIs on platforms and at stops delineating raised cycling facilities, and accessible pedestrian signals. 5. Curbside design to support transit efficiency. Where appropriate, queue-jump lanes provide opportunities for buses to move to the front of the queue, avoiding significant delays. At stops with adjacent on-street parking, transit platform bulb-outs can help people board or alight faster, and they make it easier for transit vehicles to pull back into traffic. Remove or relocate on-street parking away from transit stops and supplement it with traffic signs to ensure the space is clear for transit vehicles all the time. 6. Traffic signal control strategies. Traffic signal progression and/or coordination aims to provide a wave of “green lights” on corridors with on-street transit. Transit signal priority is another method to enhance transit performance and keep transit on schedule. Time-based turn restrictions can help prevent significant delays to transit and other drivers on busy routes. 7. Transit streets safe for walking and cycling. Create safe streets for people to walk and bike, as well as safe crossings – as pedestrians and cyclists are most often the customers who use transit. Incorporate TWSIs on curb ramps to aid navigation for the visually impaired. Design curb radii that are as tight as possible, while still accommodating the turning movements of vehicles expected to use the street, to increase pedestrian safety. 8. Transit streets are linear public spaces. Creating streets as places will enhance the attractiveness of transit and its ability to support the city’s social, economic, and environmental vitality. Repurpose underutilised space for parklets, plazas, and cafés. 9. Design for growth. As your city continues to grow and develop, streets can be designed to retain current riders and attract new riders through coordinated planning of transit expansion and new development. B.5.4 Context-Sensitive Transit Design A street’s land use and network context will inform the type of transit accommodation and priority, whether deciding on travel lanes, stop design, or intersection treatments. In addition, location-specific information will help address issues such as transit user safety, comfort, visibility, boarding/disembarking, transfers among routes and modes, and coordination of transit with land developments. Very high-frequency and very high-volume services warrant unique considerations. For example, some high-volume stops will require accommodating many waiting passengers as well as people boarding and 102 disembarking through wider sidewalks, or longer platforms and bus bays to accommodate more than one bus at a time. Where several thousand passengers per hour per direction is expected, unique and more extensive transit priority measures may be required, such as corridor-wide turn prohibitions, extended stopping prohibitions, or exclusive transit lanes. General considerations for all transit design include: • Existing and anticipated transit priority routes, ridership volumes, and transit vehicle frequency • Location of current and proposed stops, including boarding and alighting volumes • Transfers between transit routes and different modes (such as walking and cycling to take transit, or passenger drop-off/pick-up) • Access to destinations, especially special event venues, and transit rider-generating locations of all kinds • Other network priorities along the same route and location (e.g. cycling, goods movement) • Existing and potential cycling and pedestrian volumes • Number of through and turning vehicle lanes, their direction of travel (one- or two-way), and their usage throughout the day • Speed and volume of motor vehicles, and traffic congestion management • Presence of on-street parking, driveways, and other curbside uses • Presence of trees and other greening functions. B.6 Street Design for Green Infrastructure B.6.1 Key Green Street Elements Green infrastructure designed to capture rainwater (e.g. raingardens) can help minimise stormwater load on a city’s sewer system, which may come under increasing pressure with the frequency and severity of storms. Green streets can help to reduce runoff volumes and manage stormwater runoff quality. Among the many health and environmental benefits, green streets can also provide a more aesthetically pleasing street and contribute to placemaking. Trees and planting materials are most commonly installed in open landscape at grade, in planters (that may double as seating), in covered tree pits, in stormwater tree pits/trenches, in bioswales, and in rain gardens. They have numerous benefits related to ecology, air quality, temperature moderation, safety, microclimate, land value, and human well-being. Street trees and landscaping are ideally located where growing conditions are best, where people can enjoy them, and where they can be efficiently maintained. Special consideration is required for trees 103 in hard boulevard surfaces to provide adequate soil volumes and optimum growing conditions. Urban and drought tolerant plant materials and native plant species can facilitate ease of maintenance. Open planters, tree pits, and above-ground planters are all possible elements to contain trees and landscaping on streets, but aren’t considered part of the pedestrian throughway. B.6.2 Green Infrastructure Design Principles Green streets employ green infrastructure solutions to support human health and well-being and to relieve urban pressures on ecological systems, air quality, energy efficiency and water resources. Green streets are designed with attention to the ecological and hydrological functions of the street, and in particular, to the at-source treatment of stormwater runoff. The following are principles to apply when designing green roads and infrastructure: 1. Street trees and landscaping. Seek ways to incorporate and provide healthy growing conditions for trees and/or landscaping to improve air quality, mitigate urban heat-island effects, enhance ecosystem health, and contribute to community character. Select planting locations, spacing, and design details (e.g., adequate soil volume, water and sun access) so that trees and landscaping will flourish. Trees can frame and define streets, calm traffic by visually narrowing the roadway, provide shade, and add texture and visual interest. 2. Visibility and safety. Clear sightlines are important to the safety of all road users. Ensure adequate visibility is maintained, especially at street corners, traffic lights, traffic signs, transit stops, and driveways. 3. Universal accessibility. Design to provide universal accessibility, such as through the selection of materials and elements, to accommodate people of all ages and abilities. Tree pits, openings, and grates on the sidewalk aren’t considered part of the pedestrian throughway. 4. Operations and maintenance. Design for ease of maintenance, such as through passive irrigation, selecting context-sensitive native plant species, and planning for safe access to maintain green infrastructure. 5. Achieving multiple environmental objectives. Consider ways to combine environmental design, such as tree canopy expansion, stormwater retention, and microclimate moderation into single street features like roadside rain gardens. 6. Sustainable energy. Consider energy generation, use, and management by selecting, designing, and locating street elements such as solar lighting, bicycle parking machines, and street furniture to contribute to an energy efficient city. 7. Sustainable transportation. Provide greener, healthier mobility choices so that more people walk, bike, and take public transit. 104 B.6.3 Context-Sensitive Green Streets It’s possible to incorporate green infrastructure in a variety of places within the public right-of-way. The planting and furnishing zone is an ideal location for green street elements as it provides a buffer between pedestrians and vehicles. This zone may also make use of street poles for hanging planters, trellises, and solar panels as long as adequate visibility and safety are maintained. Curbsides in the roadway are where greening can often be enhanced through curb extensions, bioswales, rain gardens, permeable paving on the curb extension or edge zone, cycling facilities, parking laybys, and other green street elements. Medians or raised islands in the roadway can be good places to include trees and other landscaping, but require special attention to ensure visibility and safety for travellers and long-term maintenance. Factors to consider when designing green streets include sunlight; available right-of-way width and building setbacks; open space context; curbside accommodations for goods movement, delivery, and loading; sightlines and other safety considerations; and setbacks from intersections and other street infrastructure. B.7 Street Design for Roadways B.7.1 Roadway Design Principles The following are principles to apply when designing roadways in general: 1. Multi-modal transportation. While few passengers will walk more than 800 m to reach transit, cyclists might travel up to 5 km (usually, 2.5 km) to reach high-frequency transit services. Give reliable, convenient, and attractive mobility choices to people. Support more efficient, active, and healthier forms of travel (by foot, bicycle, transit) to reduce vehicular congestion. Provide emergency access and operations, and support goods movement and delivery by different modes. Identify and support existing and planned priority networks for each mode. 2. Safety. Fully consider road users who are particularly vulnerable in a crash or in interactions with other road users, such as pedestrians (especially children, older adults, and persons with disabilities) and cyclists. Seek ways to reduce their exposure to risk (e.g., rightsize travel lanes, re-purpose underused road space, and separate pedestrians from cyclists). Provide visible, clear, and predictable travel paths for all road users. 3. Context-sensitive target speed and reliable travel. Create a safer environment for everyone by using design to facilitate the intended speed of travel for drivers based on the street’s context. Safer speeds and driver behaviours result in fewer incidents on the roadway that can cause delays and vehicular congestion, which negatively impact emergency access and goods movement. Coordinated signals, along with target speed, can help improve consistency in travel times. Peakhour restrictions for stopping, parking, and turn movements can improve travel times along key routes.17 This also helps to manage demand and road capacity during peak travel times. 17 Not yet available in the core C:S game or in a mod, but hopefully TM:PE will add this at some point. 105 4. Placemaking. Consider existing and planned land uses, urban form, and the different uses of the street (e.g., social and economic activities) when making decisions about competing demands for space on the street. Seek ways to provide space, e.g., through building setbacks and/or re-purposing underused roadway space for streetscaping, street trees, street furniture, café or marketing areas, parklets, bicycle parking, pedestrian lighting, snow storage and removal, etc. 5. Greening and stormwater management. Limit the area of impervious materials. Seek ways to integrate street trees, landscape features, as well as water retention and treatment strategies and snow storage. Promote non-motorised modes to reduce greenhouse gas emissions and air and noise pollution. Use durable materials that contribute to sustainability and reduce the urban heat island effect. B.7.2 Design for a Multi-Modal Transportation System Street space requirements increase with vehicle speeds, as faster vehicles require more distance between them and other objects. Space requirements also decline with more space efficient modes like walking, cycling, and transit. A car on an urban arterial requires about 20 times as much space as a pedestrian or transit passenger, and five times as much as a cyclist. Transit vehicles carry far more passengers than private cars and should be given priority wherever practical to reduce congestion. Fewer cars will help free up space for other purposes, such as urban goods movement or placemaking. Whenever possible, design streets to encourage and support higher-volume and space-efficient modes like walking, cycling, and public transit. B.7.3 Design for Safety of Vulnerable Users Vulnerable pedestrians such as children, the elderly, and people with disabilities are the priority. Pedestrians are more vulnerable to serious injury or death in motor vehicle collisions, as well as in interactions with cyclists. Cyclists are also at greater risk of injury and mortality during a collision than motor vehicle occupants. Reducing speed is a critical aspect to improve safety for the most vulnerable, as visualised in Figure 20. Assess risks for the most vulnerable users, ensure dedicated space, and reduce exposure to faster modes that may harm or injure pedestrians. Shorten crossing distances and exposure of vulnerable users to vehicles in the roadway. Increase and ensure the visibility of pedestrians and cyclists to drivers. Curb extensions and rightsizing intersection corners may help address turning speeds. Where practical, implement separation between different users, and greater separation with increasing speeds. Design bicycle facilities according to context and to make cyclists more visible to turning motor vehicles. B.7.4 Design Using a Target Speed for the Street Context Target speed is the intended speed of travel for drivers based on the street’s context. For example, safe speeds around schools or busy pedestrian areas will need to be lower than on wide streets with large setbacks or land uses that don’t generate many trips. 106 Figure 20: Vehicle speed, stopping distance, and chance of survival. *Stopping distances during wet conditions. Single car length of 5.6 m. Based on a 2.5 s reaction time, representing 90th percentile of drivers. Conventional street design considers a posted maximum speed as lower than the design speed. Contextsensitive design promotes that the street includes elements so that the posted maximum speed and design speed are the same, so that drivers aren’t comfortable exceeding the intended posted speed. Speed is especially lethal to vulnerable users like pedestrians and cyclists. Field of vision is the area a person sees when their eyes are fixed in one position, as visualised in Figure 21. The risk of severe injury increases as a driver’s field of vision narrows and misses potential hazards. Street design is always more effective in shaping behaviour than posted speed limits. Incorporate contextsensitive design features when redesigning streets to achieve that street’s target (posted) speed. More consistent travel speeds support reliable and smooth traffic flows for all road users, and can help reduce traffic delays and congestion. Examples of mid-block design measures to achieve target speed based on street context include: • Rightsizing lane widths mid-block and rightsizing turning radii. • Mid-block curb extensions to rightsize roadway (e.g., pinch points to reduce vehicular speeds). • On-street bicycle or car parking. • Trees and other vertical elements (to “cause visual friction”). • Presence of pedestrians and cyclists, and facilities that support them. 107 Figure 21: Vehicle speed and field of vision. • Signals synchronized to achieve target (posted) speed. B.7.5 Design to Support Placemaking and Street Context Traditional roadway design focused on a “centreline-out” approach where the basis of street design began from the centre of the roadway, meeting the vehicle needs first without an understanding of the context that the street exists within. A best practice for transportation engineering is to take a more holistic approach – one that looks at the whole street from building face to building face. Taking a holistic view of streets means applying a “building in” perspective that first looks at the adjacent land uses and users of the street, and then the curb to curb portion of the street. Street context informs the priority functions and uses of the street, as well as details such as choice and quality of materials, need for furnishings, user amenities, and greening schemes. B.7.6 Rightsizing and Repurposing Roadway as Complete Streets On many streets, a key objective is to observe what space isn’t being used effectively, and to rightsize and re-purpose that space to achieve complete streets goals. Ensure that excess space isn’t provided for any one mode to the detriment of the safety of other modes and/or street project objectives such as safety and target speed, active and sustainable transportation options, placemaking, greening, or universal design and accessibility. Rightsizing and re-purposing roadway space involves redesigning the physical space and using geometric design to improve safety conditions for everyone using the street. Design techniques include: • Chicanes (or road narrowings), such as on-street parking or curb extensions, that alternate on a 108 street or at intersections. • Reconfiguring four lanes into three, with a shared turn lane as the middle lane. • Reviewing for adequate corner radii for truck routes or transit vehicles. • Rightsizing vehicular lanes and re-purposing space to add/widen on-street parking and/or bike lanes and/or sidewalks and boulevards. • Re-purposing or redesigning sidewalks and boulevards to ensure that the pedestrian throughway isn’t cluttered or obstructed, such as by moving a transit shelter to the back of a sidewalk onto private property through an easement, or providing outdoor café patio seating using a parklet. B.7.7 Traffic Calming The need for traffic calming devices is often an indication that the street isn’t well-designed to achieve its desired target speed for vehicles. The better approach is to seek opportunities through street redesign projects to rightsize and re-purpose street space to achieve complete streets objectives. When implementing traffic calming, treatments intended to curtail motor vehicles should exempt cyclists, not be located on transit routes, and should accommodate emergency vehicles and winter maintenance requirements. B.7.8 Roadway Zones The roadway is generally defined as the space between the curbs. It functions primarily to support the movement of people and goods by various modes, including transit, bicycles, and motorised vehicles. The roadway may also include parking or loading areas, greening, placemaking (such as parklets in the curb lane) and other uses. Vehicle travel lane widths can range from 3 m to 3.5 m depending on context and constraints, including land uses; presence of pedestrians, cyclists, and transit; truck volumes; emergency services; posted speed; on-street parking; etc. Curb lane widths depend on whether there are dedicated cycling facilities – if there aren’t any, the curb lane width should still be designed to enable a car to safely pass a cyclist on the roadway. Curb extensions should be considered where on-street parking exists, as the extensions can be on either side of the on-street parking and provide street space for features such as benches, trees and plantings (for stormwater management), surface transit stops, and multi-unit bike racks to increase parking. Within the extension zone, extend the sidewalk into the parking lane at intersections, a transit stop, or a midblock crossing to reduce pedestrian crossing distances and improve pedestrian visibility. Provide curb extensions on frequent transit corridors and streets with high vehicle or pedestrian volumes and long crossing distances to improve pedestrian safety. Where appropriate, extend a curb extension around a corner onto the cross street. Medians or raised islands may be applied for different reasons – they can be used to manage or restrict access, provide space for turn lanes (and turning vehicles), facilitate pedestrian crossings, placemaking, and provide space for greening. Since medians typically require a wider right-of-way, one must weigh the 109 benefits of a median against using the space to support other uses and facilities (e.g., curb extensions, cycling facilities, sidewalk and boulevard widening for pedestrians and streetscaping). In addition, medians or raised islands can impact emergency vehicles accessing properties and intersecting side streets, which should be considered in design options. B.8 Highway Traffic and More Lanes New lanes don’t help traffic jams on highways because: 1. People who avoided highways before because they were busy will now want to take them again, since there’s more lanes and they think it’ll be less busy; and 2. When a transport mode is faster, we tend to use it to go further rather than spending less time travelling. Thus, new infrastructure simply allows people to live further from work, etc. Alternatives include tolls, and/or reducing speed on highways to make them less attractive. B.9 Street Design for Intersections B.9.1 Intersection Design Principles The following are principles to apply when designing intersections: 1. Safety first: Intersections are where the most points of conflict occur between different street users. The design of intersections should first and foremost ensure safe crossing for the most vulnerable users. 2. Predictability: Provide clear guidance for all users on where crossing movements are expected and the correct path of permitted movements. Simplify complex intersections wherever possible. 3. Visibility: Ensure unobstructed sightlines among road users at intersections. Locate crosswalks close to the intersection to improve the visibility of pedestrians to drivers. Reduce physical barriers and visual clutter. 4. Multi-modal: Select traffic controls based on equitable consideration of all street users, the street’s context, and role in the network. Analyse capacity from a multi-modal perspective, focusing on movement of people rather than vehicles. 5. Accessibility: Incorporate accessible design at intersections such as TWSIs, curb ramps or depressed curbs, accessible pedestrian signals, walk speeds at crossings for all ages and abilities, and access to transit stops. 6. Compact design and shorter crossings: Compact intersections tend to lower motor vehicle operating speeds and enable more eye contact, which increases safety. They also minimise pedestrian crossing distances and exposure to risk for vulnerable road users. They can also shorten signal cycle lengths which benefits all modes by reducing delay and improving convenience. 110 7. Active transportation: Observe and anticipate pedestrian and cyclist desire lines to inform design based on street context. For example, provide depressed curb ramps and wider crosswalks in locations with higher pedestrian volumes, and bike boxes where needed to enhance safety for cyclists making turns. 8. Transit: Incorporate transit stops at intersections to allow for convenient transfers for transit users. Consider transit priority measures based on street context. 9. Placemaking: Depending on street context and width, re-purpose space to enhance quality of life with greening, street furniture, or public art gateways, especially to define the entrance to unique neighbourhoods. 10. Maintenance and operations: Intersections should function well for all users all year, e.g. design to prevent ponding at ramps and snow from blocking access to pedestrian push buttons. 11. Manage stormwater: Incorporate green street elements depending on street context and width, such as on curb extension to reduce stormwater runoff and recharge ground water, improve air quality, and beautify. B.9.2 Key Needs and Perspectives of Each Road User A key starting point is to understand the primary needs of each modal user. Keep in mind that some street elements that improve the conditions for one mode may reduce the comfort or convenience of another, but these should never supersede the need for safety of all road users, especially the most vulnerable. For pedestrians, this includes: • Lower motor vehicle speeds, by rightsizing vehicle lanes and curb radii, and traffic calming on local or side streets such as installing curb extensions or raised intersections. • Reduced exposure to risk and conflicts, with clear sightlines and visibility, shorter crossing distances, adequate pedestrian space on corners, and adequate crossing time. • Accessibility and universal design for all, with curb ramps or depressed curbs, TWSIs, accessible pedestrian signals, dedicated space (away from mixing with cyclists and vehicles), sufficient walk time for all ages and abilities, and adequate sidewalk and crosswalk widths given pedestrian volumes and the street context. • Adequate signalised crossing opportunities. • Desire lines inform crossings, so that crosswalks align with the path of travel. • Placemaking considerations, based on street context, such as buildings that front on the street or have transparent storefronts (for “eyes on the street”), transit shelters and benches. For cyclists, this includes: 111 • Lower motor vehicle speeds, by rightsizing vehicle lanes and curb radii, and traffic calming on local or side streets such as installing curb extensions or raised intersections. • Reduced exposure to risk and conflicts, with clear sightlines, shorter crossing distances, and dedicated space, separation and signal design for cyclists that are context sensitive. • Wayfinding on cycling routes and how to stay on the network and navigate routes, especially at complex intersections. • Nearby bicycle parking stations to support cycling options for people, especially at transfer points like transit or major destinations. For transit users, this includes: • Good pedestrian and cycling connections (see the previous sections), with sidewalks, transit shelters and benches, nearby bicycle parking, wayfinding, and cycling route information. • Reduced exposure risk and conflict, such as curb extensions at bus stops, transit-only lanes, and far-side bus stops. • Accessibility for all with context-specific stop spacing, platforms, bus pads and sidewalk ramps with TWSIs, well-lit transit stops, and adequate pedestrian throughway widths. • Reliable and improved travel times and schedules, with context-specific measures such as frequent headways, signal priority, queue-jump lanes, and seamless connection to other transit. • Placemaking considerations based on street context, such as buildings that front on the street or have transparent storefronts (for “eyes on the street”), safe and comfortable waiting areas, and transit-supportive developments. For motorists (i.e. all drivers), this includes: • Reduced conflicts and severity of crashes, with clear sightlines and visibility, dedicated space for all modes, and predictability of expected movements (e.g. using pavement markings, signage and signals/traffic controls). • Safe turning options, with context-specific measures such as phase-separated turning movements, placement of advanced stop bars, and clearly marked turn lanes. • Wayfinding, with large visible street name signs and other wayfinding information to help people navigate the city, e.g. to locate parking options. • Reliable and improved travel times, using coordinated signal timing, responsive vehicle detection and signals, traffic regulations, and congestion reduction by shifting more trips to walking, cycling and transit. 112 B.9.3 Crosswalks Crosswalks that are at least as wide as the sidewalks that approach them, especially at busy intersections, will improve pedestrian safety by reducing crowding and encouraging pedestrians to stay within the crosswalk while crossing. Maintain sightlines and visibility for pedestrians and motorists by ensuring that the approach to the crosswalk is free of such obstructions as signs, structures, or landscaping. Enhance the visibility of crosswalks through effective lighting, to help alert motorists to the most important crossings and points of potential conflict. Forbid on-street parking within 10 m of intersections and mid-block crossings to improve pedestrian and motorist sightlines. To improve pedestrian visibility and reduce vehicle speeds, provide raised (not elevated) crosswalks. Provide stop lines in advance of the crosswalk at signalised or stop-controlled intersections, to help ensure that vehicles don’t encroach upon the crosswalk and impede pedestrian flow. Provide yield lines in front of mid-block crosswalks to indicate where vehicles should stop, so that vehicles approaching in adjacent lanes can better see a pedestrian in a crosswalk. Consider special paving treatments such as brick, coloured concrete, and pavers, in conjunction with crosswalk markings to enhance the visibility of crosswalks, improve aesthetics, and serve as a visual and tactile cue to drivers. At intersections with high pedestrian volumes and where conditions are favourable, innovative solutions such as pedestrian scrambles, which stop all vehicular traffic at an intersection and allow pedestrians to cross an intersection in every direction, including diagonally at the same time, may improve pedestrian movement. B.9.4 Accessibility and Universal Design of Intersections To eliminate the need to step down from a curb to the roadway to cross at intersections, design intersections with adequately wide and properly designed curb ramps and depressed curbs at intersections. A curb ramp or depressed curb is needed for people with physical disabilities or even people using shopping carts or strollers. A fully depressed curb has the benefit of removing trip hazards (e.g., the section of curb between crosswalks), especially with high volumes of pedestrians. Curb ramps can also be found at transit stops. TWSIs must be included and placed as discussed in subsubsection B.3.2. Typical walk speeds when crossing the street are 1 m s−1 to 1.2 m s−1 , but this walking speed could exclude one-third of older pedestrians, 70 % of elementary school aged children, and 90 % of pedestrians using an assistive device such as a walker or cane. Where there are higher pedestrian volumes and the expectation of pedestrians with disabilities based on demographics and land use context, the walk speed for traffic signals should be in the range of 0.8 m s−1 to 1 m s−1 to enable safe crossings for people of all ages and abilities. The hierarchy of vulnerable users has pedestrians at the top because they’re unprotected when encountering faster-moving road users, such as cyclists and drivers. At intersections and mid-block locations, it’s important to provide dedicated space for pedestrians and separation from cyclists and motor vehicles, whether on the sidewalk, at transit stops, and at intersections – on street corners and crosswalks. 113 Safe, passable space is needed to accommodate people using assistive devices and the context-specific pedestrian volumes at intersections. Sidewalk and crosswalk widths should be commensurate with the intensity of pedestrian activity and volumes at intersections, to minimise crowded conditions, and potential conflicts among modes. B.9.5 Context-Sensitive Intersection Design Three main intersection situations exist. Main Streets or Mixed-use Connectors often have a combination of high traffic volumes, high approach speeds, transit stops, and pedestrian and cycling activity. The challenge becomes balancing the need to reduce risk to all road users, while accommodating traffic capacity and turning movements for larger vehicles. Consider the following design treatments: • Due to the size of these intersections, clear alignments and pavement markings are needed to guide the paths for all road users and to provide predictable and visible movements. • To help pedestrians of all ages and abilities to safely cross wide roadways, consider pedestrian crossing islands, zebra crosswalk markings, standard curb radii, leading pedestrian interval signals, adequate space for pedestrians waiting on street corners (e.g., declutter corners, rightsize corner, set back buildings, etc.), and other pedestrian safety measures. • To make cyclists more visible to other road users, mark bicycle facilities through the intersection, including bike boxes or queue boxes, providing designated bicycle signal phases where appropriate, and regulatory and warning signs for motorists where notable conflicts exist. • Analyse intersection capacity from a multi-modal perspective and focus on moving people rather than vehicles, such as by prioritising transit, in order to reduce traffic congestion as intersections become busier with residential and employment growth. Consider planned land uses, anticipated mode split shifts, and latent demand for pedestrian, cyclist, and transit users during the design process. Design becomes complex for situations where lower volume streets intersect with higher volume streets (i.e. intersections between residential streets with main, civic, and connector streets), because traffic flow and capacity will focus on the busier street, yet side streets and their users also need to be accommodated. These intersections may be signalised, or have two-way stop control such as stop signs. Consider the following design treatments: • Clearly mark controlled pedestrian and cyclist crossings (i.e. with stop control, flashing lights, or signals) wherever they exist. • Analyse and design intersections taking into account the transportation network. It may not be possible or practical to accommodate all movements at all times (e.g. through or left-turn movements from the side street) at a two-way stop-controlled intersection. 114 • If there is heavy traffic on Main, Civic, or Connector Streets, with insufficient gaps in traffic for safe turns, consider access management strategies such as consolidating and limiting driveways, laybys or other conflict points, and potential turn prohibitions from side streets. Residential street intersections are characterised by low traffic volumes and slower speeds. In addition, people of all ages and abilities may be on foot in the neighbourhood for various activities such as getting to school, transit or nearby destinations. Consider the following design treatments: • Enhance pedestrian safety with crosswalks, all-way stop control, curb extensions, raised intersections, and rightsizing corner radii as well as complementary mid-block measures (e.g., chicanes, mid-block curb extensions, etc.). • In general, delay and capacity aren’t key factors for residential intersections as they have low volumes and speeds. Design of these intersections focuses on pedestrian accessibility and connectivity to homes, parks, community centres, and the pedestrian network to transit and other streets. Cyclists are often accommodated in a similar manner to motor vehicles or are supported by bike-friendly street designs noted in the Cycling chapter of this document (e.g., adequately wide curb lanes, bicycle detection at actuated signals, etc.). • While larger vehicles such as fire, waste collection, and snow-plow trucks are important to consider, the turning movements for these vehicles will typically use the width of the roadway to negotiate turns. B.9.6 Intersection Elements and Geometric Design The size of curb radii affects the turning speed of vehicles, pedestrian crossing distances, visibility, and space available for pedestrians waiting to cross the street. The decision to include pedestrian crossing islands or medians should be weighed against using that space instead for adequately wide sidewalks, cycling facilities, and planting and furnishing zones. Depending on street context, there may be features that enhance the sense of place while balancing the need for safety and clear sightlines. Features used at intersections include but are not limited to: wayfinding signs, maps or information pillars; landmarks; gateway features; meeting locations with seating; pedestrian lighting; pedestrian crossing islands with landscaping; decorative pavers; and carefully selected street furniture and/or street art. Cross rides indicate where cyclists may ride to cross a roadway at controlled crossings, alongside pedestrians. Adequate width and attention to design are required for the crosswalk and cross ride to prevent conflicts among cyclists and more vulnerable pedestrians of all ages and abilities. A left-turn queue box consists of pavement markings indicating a safe and designated area for cyclists making a left-turn manoeuvre. These may be accompanied by a right turn on red restriction if the queue box is in the path of vehicular right turns. 115 Transit queue jump lanes should be considered for areas where heavy volumes of mixed traffic negatively impact transit service, depending on space and impacts to other road users. Right turn channels present safety concerns for all road users, as they result in poor sightlines for all in addition to significant barriers to people with disabilities. Remove wherever possible. Roads that run overhead or underground are called grade-separated. Such facilities create significant barriers between neighbourhoods and for vulnerable road users. B.9.7 Intersection Signals and Other Traffic Controls When reviewing or making decisions about signals or traffic control devices, there are some key considerations to keep in mind for the safety and comfort of all road users regardless of age and ability: • Leading pedestrian intervals give pedestrians a five second head start, making them more visible to turning motorists. • Safety first: Consider the use of a combination of physical design (e.g., rightsized traffic lanes and corner radii) and traffic control features to achieve the desired target speed for the street’s context. • Use future, not past data: Use projected future volumes (and not past or existing data) for all modes in the analysis and review of future infrastructure, new developments, and environmental sustainability. • Spacing between controlled crossings: Consider land uses, density, pedestrian volumes, and demographics when looking at spacing of controlled crossings. All pedestrians, especially people with disabilities, benefit from having more closely spaced crossing opportunities. The desire for widely spaced intersections for faster motor vehicle movements needs to be weighed against the impacts on safety, connectivity, and accessibility of pedestrians and cyclists. • Adequate crossing times and walk speeds accounting for all ages and abilities: Consider how to best accommodate slow walkers through the provision of the shortest possible crossing distance and adequate signal time. Long crossing distances not only increase pedestrian exposure to risk of collision in the street, they also require longer signal cycles to give enough time to safely cross the street. • Short signal cycles: In general, short signal cycles (60 s to 90 s) are preferred as they provide predictable and regular crossings, and generally minimise overall delay for all users. While short cycles tend to encourage people to obey the signals compared with locations with longer delays, the short cycle length needs to be weighed against the safety benefits of separated signal phases, such as having dedicated left-turn signals. 116 B.10 Street Network Design B.10.1 Fine-Grained Street Networks Studies show that higher levels of intersection density (i.e., more intersections) result in lower levels of overall travel by car and higher likelihoods of travel by sustainable modes. A pattern of smaller blocks and connected streets makes it possible to travel along direct routes. A connected street network extends the reach of transit, walking, and cycling, and closes the gap between destinations; it also brings origins and destinations closer together and makes access to everyday activities more convenient by sustainable modes of travel. Street connectivity may be of highest priority in established Urban Centres and is most critical near frequent transit stops or stations. Design block patterns with short block lengths, to create a connected grid of streets that minimises pedestrian and cyclist travel distances between points. Blocks should generally range in length between 200 m to 250 m to promote walkability, and shouldn’t exceed 250 m. Blocks longer than 250 m should only be considered where shorter block alternatives aren’t feasible; in such cases, provide publicly accessible through-block pedestrian walkways (at least 6 m wide) or a linear park. Public pedestrian walkways should include pedestrian-scaled lighting, and provide clear sightlines allowing view from one end of the walkway to the other. Ensure landscaping doesn’t create blind spots or hiding places in walkways. Plan for spacing of approximately 800 m between arterial streets, with local blocks no longer than 150 m. Ensure that internal streets for large development projects are accessible to the public, and that the development is permeable for pedestrians, cyclists, and emergency vehicles. To further minimise the visual impact of blocks, turn lots located on the end of the block 90° to face the street. Reverse frontage lots should be also avoided. Achieve positive frontage on arterial and collector streets through the use of rear lane access, rear access from local streets, or single-loaded service streets. Provide a mix of lot sizes and orientations to ensure a diversity of housing types and designs, and to enhance visual interest along the streetscape. Avoid dead-ends, culs-de-sac, and running streets through green spaces. Provide safe and convenient pedestrian crossings of arterial streets near transit passenger facilities. Where appropriate, provide closely-spaced pedestrian crossings of primary streets to improve access and convenience to both sides of the street (e.g., in Urban Centres). Provide at-grade pedestrian crossings of primary streets, rather than over- or under-passes, to avoid delaying pedestrian travel. Provide pedestrian-, cyclist-, and/or transit-only crossings along desire lines to increase the convenience and competitiveness of these modes and to help overcome physical barriers to movement, such as major highways and rivers. B.10.2 Coordinated, Multi-Modal Transportation Networks This approach recognises that not every street will serve every mode of transportation in the same way. A multi-modal network includes different types of streets and pathways that combine to provide optimal connectivity for all modes within a community. Designate a network of arterial streets that connect major destinations and provide direct paths of travel, avoiding unnecessary breaks and diversions, in order to achieve more efficient and convenient transit 117 corridors. Avoid concentrating vehicle traffic on only a few corridors by providing multiple, relatively even-spaced, and well-connected arterial streets. Fine-grained design discussed previously creates an effective street network providing for quick pedestrian routes and efficient transit operations. Create a well-connected network of bike lanes, priority lanes, routes, and paths that provide direct connections to local destinations and transit passenger facilities. Select bicycle priority streets, where possible, that have low traffic volume and a fairly flat terrain to provide convenient connections to transit passenger facilities. Ensure that the bicycle network provides strong connections to important transit nodes. Even where facilities for cyclist through-movement are provided on low-volume streets adjacent to major arterials, design arterials for safe access by cyclists to destinations along those streets. Provide additional connectivity by creating bicycle boulevards or neighbourhood greenways on streets with low traffic volumes. 118 Figure 22: Avoid towers in a park. Free-standing towers disrupt the pedestrian-oriented scale, character, and vitality of the street. C Tall Building Guidelines The following section is derived from the City of Toronto’s Tall Building Design Guidelines, March 2013. C.1 Introduction The design and placement of tall buildings should make a positive contribution to the public realm, and fit harmoniously within the surrounding context and skyline. Avoid free-standing towers without bases or a direct relationship to the street, e.g. “towers in a park” as shown in Figure 22. C.2 Site Context C.2.1 Fit and Transition in Scale Ensure tall buildings fit within the existing or planned context and provide an appropriate transition in scale down to lower-scaled buildings, parks, and open space. When tall buildings are proposed within an identified growth area, design towers nearer to the edge of the growth area to be progressively lower in height than those in the “centre”, i.e. the location of greatest intensity and highest order transit, as shown in Figure 23. Appropriate fit and transition in scale may mean that not all sites are suitable for tall buildings. In general, appropriate fit and transition is achieved when tall buildings: • Respect and integrate with the height, scale and character of neighbouring buildings; • Reinforce the broader city structure; • Provide horizontal separation and transition down to lower-scale buildings and open space (as seen in Figure 24); and 119 Figure 23: A progressive transition in the height and scale of tall buildings from the centre of a growth area down to a lower-scale area. • Maintain access to sunlight and sky view for surrounding streets, parks, public or private open space, and neighbouring properties, as shown in Figure 25. Angular planes (seen in Figure 26) are a commonly applied measure to provide appropriate transition in scale from tall buildings down to lower-scale areas, limiting shadow and overlook on neighbouring properties that are lower-scale, and limiting shadow and loss of sky view on adjacent streets and open space. They are also used to protect access to sunlight and sky view for streets, parks, public and private open space. Typically, a maximum of 45° for an angular plane is best. C.2.2 Sunlight and Sky View Locate and design tall buildings to protect access to sunlight and sky view within the surrounding context of streets, parks, public and private open space, and other shadow sensitive areas. Consider different placements of tall buildings within the surrounding block to ensure maximum sunlight penetration and sky view to lower-scale areas. While limiting the scale and height of the base building to appropriately frame the public realm, maintain access to at least five (5) hours of sunlight on the opposite side of the street. Consider the cumulative effect of multiple towers on resulting shadowing. Shadow-sensitive areas include places like play fields, schoolyards, and cemeteries. Heritage properties and local landmarks may also be shadow-sensitive, and should have shadows cast on them minimised. Cast shadows are especially important depending on the local climate; cold locations with long winters need as much sunlight as possible. 120 Figure 24: Horizontal separation distance, and a change in base building height and form to support tall building transition down to a lower-scale area. Figure 25: A new tall building fitting within an existing context of other tall buildings of consistent height. Note the appropriate separation distance between buildings of similar height. 121 Figure 26: An angular plane, and direct relationship in base building height and form to support tall building transition down to a lower-scale area. C.2.3 Prominent Sites and Views from the Public Realm Provide an appropriate, high-quality design response for tall buildings on or adjacent to prominent sites, and when framing views from the public realm to prominent sites. Well-placed (and well-designed) tall buildings on prominent sites can themselves become landmarks, providing points of orientation and visual interest within a city. Most often, however, tall buildings typically play a secondary role to what is being viewed at a pedestrian level. For example, the design and placement of the base building, tower and open spaces work together to open up or better frame the view. Less frequently, tall buildings may be an integral part of shaping what is being viewed, such as with skylines. When a tall building frames a view from the public realm to a prominent site or other important feature, the design and placement of the tall building should play a supportive role to those sites and features. C.3 Site Organisation C.3.1 Building Placement Locate the base of tall buildings to frame the edges of streets, parks, and open space, to fit harmoniously with the existing context, and to provide opportunities for high-quality landscaped open space on-site. Where the existing setback pattern is consistent and not planned to change, align new base buildings with neighbouring building frontages. Where existing setback patterns vary on either side of a tall building site, locate and design the base building to resolve the differences. On corner sites, respond to the setback pattern and alignment of neighbouring buildings on both streets. Provide greater building setbacks at strategic points, such as intersections. 122 Figure 27: A series of street-related entrances promote interaction between the building interior and the public realm. Public art and signature architectural features also effectively highlight primary building entrances. C.3.2 Building Address and Entrances Ensure primary building entrances front onto public streets, are well defined, clearly visible, and universally accessible from the adjacent public sidewalk. Differentiate between residential and commercial entrances in mixed-use buildings. Where building entrances are set back by a plaza or forecourt, maintain high visibility and direct, universal access from the public sidewalk. Coordinate the location of building entrances with transit stops and stations. Highlight corner and mid-block entrances, as shown in Figure 27. C.3.3 Site Servicing, Access, and Parking Locate “back of house” activities such as loading (commercial) and vehicle parking underground or within the building, away from the public realm and public view. Avoid areas where high pedestrian traffic is expected by directing vehicular access to on-site parking, loading, and servicing facilities to local streets and rear lanes, and not from the arterial street. Where feasible, incorporate shared driveways in order to reduce the extent of interruption to pedestrians. Where vehicular access is only feasible from arterial streets, a front driveway may be permitted, provided that mutual access with adjacent properties are provided wherever possible, and that the access point is located away from areas where high pedestrian activities would occur. Through-lanes (public or private) are encouraged to minimise vehicle turnarounds. Organise dropoff areas into the side or rear of the side. When located at the rear, provide direct visual and physical 123 pedestrian access to the street frontage. Provide taxi stands and bus drop-off areas on private property for tall buildings which contain hotels, or commercial and office uses. Drop-off areas should include the following elements: • Drop-off access should be from rear lanes or secondary streets wherever possible. Avoid placing drop-off areas at highly visible locations, such as street termini. • Pedestrian connections should lead directly from drop-off areas to street frontage and to the front entry of the building. Provide weather protection for outdoor waiting areas, to make getting to and from the site more comfortable. • Design drop-off areas to be pedestrian-oriented, minimise conflicts with pedestrian routes, and to include decorative paving material, textures, or colours to emphasise pedestrian connections. Design any above-grade parking structures to reinforce the intended built character, and blend into the streetscape through façade treatments that conceal the parking levels and give the visual appearance of a multi-storey building. Façade design of above-grade parking structures should complement adjacent buildings in terms of openings, vertical articulation, materials, and colours. Pedestrian amenities such as awnings, canopies, and sheltered entries are encouraged. Locate pedestrian entrances for parking structures adjacent to main building entrances, public streets, or other highly visible locations. Locate exterior vehicular ramps and garage entrances to parking structures at the rear or side of buildings, away from main building frontages and streets. Avoid locating ramps/entrances at street corners or view termini. C.3.4 Publicly Accessible Open Space Provide grade-related, publicly accessible open space within the tall building site to complement, connect, and extend the existing network of public streets, parks, and open space. Providing good quality, publicly accessible open space within a tall building site can help new development fit within the existing context and is particularly important when there is a shortage of public park space in the surrounding area. Locate and design publicly accessible open space to: • Read as a public place and include features to encourage year-round use; • Provide direct visual and physical connections to public streets, parks, and open space, including adjacent pedestrian and cycling routes; • Complement and connect with publicly accessible open space on neighbouring properties, where possible; • Maximise safety, comfort, and amenity, including access to sunlight, clear views to and from adjacent streets and buildings, universal accessibility, pedestrian-scale lighting, four season landscaping, seating, public art, and protection from wind and inclement weather. 124 Figure 28: Tall building sites offer a broad range of publicly accessible open space opportunities. On larger sites, use publicly accessible open space to provide through-block pedestrian connections. Define and animate the edges of publicly accessible open space with well-proportioned base buildings and active uses at-grade. Types of publicly accessible open space may include: • Courtyards: Landscaped open space, located in the centre of a single or consolidated block with no direct street frontage. • Forecourts: Landscaped open space between the public sidewalk and the main entrance of a building. • Landscaped Setback: Space between the public sidewalk and building face characterised by hard or soft landscape treatment. • Plazas: Animated gathering place with predominantly hard surfaced landscape features flanking a public street. • Urban Gardens: Landscaped space, usually of intimate scale, open to a public street, located and oriented to provide maximum sunlight during midday. • Walkways: Exterior public pedestrian route at street level, usually providing connection through the block. A galleria, when glazed and enclosed. Examples of such spaces are shown in Figure 28. 125 Figure 29: Tall buildings require a broad range of private open spaces to meet the needs of building occupants. C.3.5 Private Open Space Provide a range of high-quality, comfortable private and shared outdoor amenity space throughout the tall building site. Locate and design shared private outdoor amenity space to maximise access to sunlight, while minimising noise and air quality impacts from site servicing (mechanical equipment, etc.). In residential or mixed-use developments, include places for pets and pet runs either at-grade or on a shared rooftop space, and provide access to secure outdoor play space and equipment for families. Where possible, ensure such spaces are directly overlooked by windows and balconies. Examples of different types of private open spaces are shown in Figure 29. C.3.6 Pedestrian and Cycling Connections Provide comfortable, safe, and accessible pedestrian and cycling routes through and around the tall building site to connect with adjacent routes, streets, parks, open space, and other priority destinations, such as transit and underground courses. Providing direct, convenient, safe, highly visible, and universally accessible connections to the surrounding public realm is key to promoting walking and cycling as viable transportation choices for building 126 occupants. Design on-site pedestrian and cycling routes to read as publicly accessible; be direct, logical, and continuous; and include landscaping, pedestrian-scale lighting, and other amenities to enhance safety, comfort, and four season use. A network of above- and below-grade connections to local destinations can also help tall buildings integrate with the surrounding context, but should never be at the expense of good connections at-grade to support vibrant public streets and sidewalks. Prioritise pedestrian and cyclist circulation and connectivity with adjacent sites. C.3.7 Public Art Pursue public art opportunities on tall building sites or adjacent public lands to enhance the quality of the development, the public realm, and the city. Public art enriches the public realm by making buildings and open spaces more interesting, engaging, and memorable. Where applicable, provide adequate building setbacks and space around public art so that it can be properly viewed and experienced from the public realm. Public art opportunities on tall building sites may include: • A conceptual framework to organise open spaces including parks, plazas, setbacks, or streetscapes; • An independent sculpture or two-dimensional work that marks an entryway, corner, feature area, or view terminus; or • Visual arts combined with landscape design, functional, and decorative elements of a site, such as water features, lighting, canopies, seating, paving, walls, fences, etc. C.4 Base Building Design C.4.1 Base Building Height and Scale Design the base building to fit harmoniously within the existing context of neighbouring building heights at the street and to respect the scale and proportion of adjacent streets, parks, and open spaces. The role of the base building is to help a tall building fit harmoniously within the existing or planned street wall context; define the edges of adjacent streets, parks, and open space at good proportion; and maintain access to sunlight and sky view for pedestrians and neighbouring properties. Where there is an existing context of street wall buildings with consistent height, align the new base building with the height of the street wall. In the absence of a consistent street wall height context, provide a minimum base building height between 3 to a maximum of 80 % of the adjacent street width as shown in Figure 30 (up to a limit of 24 m, or 5 storeys). Doing so provides consistency in proportion and maintains access to at least five (5) hours of sunlight on the opposite side of the street at the spring and fall equinoxes. On wider streets (30 m to 45 m in width), additional base building height may be appropriate with a stepback of at least 3 m, provided that the total height doesn’t exceed 100 % of the adjacent street width as shown in Figure 30 (up to a limit of 24 m, or 7 storeys). This ensures the base 127 Figure 30: The height and scale of the base building responds to the scale of neighbouring buildings and the street proportion. doesn’t overwhelm the pedestrian environment, compound tall building impacts on shadow and sky view, and contribute to a disproportionate tall building composition. For sites where the adjacent context is lower-scale and not anticipated to change, provide a transition in the base building height down to the lower-scale neighbours. Match at least a portion of the base immediately adjacent to the lower-scale context with the scale and height of neighbouring buildings. Many tall building sites, including corner sites, have multiple frontages facing streets, parks, and public or private open space. The scale, height, and form of the base building may need to vary in order to respond appropriately to differences in adjacent building height, character, open space size, and street width for each face. The appropriate height for base buildings facing small open spaces within a site is often lower scale than may be appropriate for street frontages. Provide a smooth transition where a change in base building height, scale, and character occurs. C.4.2 Street Animation Line the base building with active, grade-related uses to promote a safe and animated public realm. Active, street-related commercial and retail uses are often the most desirable activity generators in the base building, since the resulting pattern of entrances and display windows provides multiple points of interaction between the building interior and adjacent public realm. On streets with a mixed-use or commercial character, line the base building with a series of active commercial and retail uses. Where possible, dedicate at least 60 % of street frontage to active retail uses. Multiple building and storefront 128 entrances, spaced an average of 7 m to 10 m along street and open space frontages, are encouraged. Conversely, lobbies, large-format commercial uses, private indoor amenities, and guest suites tend to be relatively inanimate spaces that lack a strong or engaging connection with pedestrians and do little to improve safety compared to the constant surveillance of street activity. Where large-scale spaces are necessary on the first floor, locate them toward the building interior and line them with active uses along all street and public open space frontages. On streets with a mainly residential character, line the base building with grade-related residential units such as townhouses (except along arterial roads where smaller apartments with multiple entrances would work better) with front entrances and windows to living spaces facing the street. This can create a pleasant and animated base building alternative, broaden the range of housing choices, and increase the opportunity for social interaction and natural surveillance. C.4.3 Public-Private Transition Design the base building and adjacent setback to promote an appropriate level of visual and physical access and overlook reflecting the nature of building use at-grade. For all public entrances, such as entries to commercial uses or shared lobbies (public and private), provide direct, universal access, flush with the public sidewalk. Along mixed-use and commercial street frontages, avoid locating balconies (projecting or inset) within the first 3 storeys of the base building. Between 3 and 6 storeys, inset balconies behind the street wall. For private entrances to ground floor residential units, provide grade separation (up to 0.9 m) and a minimum of 3 m distance separation from the front property line. Filter and screen views into private dwelling units with soft landscaping, but ensure views to streets and open space are maintained for natural surveillance. Examples of transition for public and private spaces are shown in Figure 31 C.5 Tower Design C.5.1 Tower Placement Place towers away from streets, parks, open space, and neighbouring properties to reduce visual and physical impacts of the tower and allow the base building to be the primary defining element for the site and adjacent public realm. Towers that meet the ground directly can generate uncomfortable wind conditions, establish an overwhelming street proportion, and create an oppressive sense of pedestrian scale. Setting the tower back at least 3 m and more where possible reinforces the base building as the defining element for the public realm, enhances pedestrian comfort by absorbing downward wind shear, and limits the visual impact of the tower at grade. Generous tower stepbacks, substantially greater than 3 m, as well as coordination of 129 Figure 31: Treatment of the transition space between the public sidewalk and building interior reflects the differing needs for access and privacy between residential and commercial frontages. tower placement with the location of other tall buildings, may also improve wind conditions and access to sunlight and sky view in the surrounding area. Coordinate tower placement with other towers on the same block and adjacent blocks to maximise access to sunlight and sky view for surrounding streets, parks, open space, and properties. Step back the tower (including balconies) at least 3 m from the face of the base building, along all street, park, and open space frontages (including publicly accessible or private shared open space and rooftop amenity within the site). Tower stepbacks greater than 3 m are encouraged and may be necessary to fit tall buildings within an existing context. As an option within the stepback, up to one third of a point tower frontage along a street or open space may extend straight down to the ground (as shown in Figure 32. At these locations, provide permanent building features such as canopies and overhangs to mitigate pedestrian-level winds. C.5.2 Separation Distances Setback towers from the side and rear property lines, or centre line of an abutting lane, by 12.5 m or greater. Provide separation distances of 25 m or greater between towers, measured from the exterior wall of the building, excluding balconies. Placement of towers should minimise negative impacts on the public realm and neighbouring properties, such as shadowing, pedestrian-level wind, and blockage of sky view, and maximise environmental quality of building interiors, including sunlight, ventilation, and privacy. The minimum separation distances are established to ensure tall buildings achieve the following objectives for the protection of sky view, privacy, and daylighting: 130 Figure 32: The tower frontage, including balconies, steps back at least 3 m from the base building. As an option, up to one third of the point tower frontage within the stepback extends to the ground. • Sky View between buildings is essential to maintain the character, usability, and quality of streets, parks, open space, and neighbouring properties. Lack of sky view can also negatively affect the microclimate and sense of pedestrian scale at-grade. • Privacy objectives, particularly for residential units, are achieved when tower orientation, appropriate facing distances, and setbacks combine to mitigate overlook between the windows or balconies of one building and those of another. • Daylight access in the building interior is an important component of residential liveability, workplace productivity, and sustainable building practice. If towers are located too close to side or rear property lines, the need to provide access to sunlight, sky view, privacy, and daylighting may restrict adjacent sites from developing in a similar manner. Thus, minimum tower stepbacks from side and rear property lines are required as shown in Figure 33. Where the existing context is characterised by separation distances greater than 25 m, provide tower setbacks and separation distances in keeping with the more generous spacing established by the context. Even if tall buildings in close proximity to other tall buildings meet the minimum required separation distances, setbacks, and stepbacks, towers should be further shaped, placed, and articulated to increase the actual and perceived distances between adjacent building elevations, as shown in Figure 34. If buildings are taller, provide greater setbacks and separation distances proportionate to increases in building size and height. Use the widest dimension of the tower as a guide to determining setbacks and separation distances, as shown in Figure 35. C.5.3 Tower Orientation and Articulation Organise and articulate towers to promote sustainability and visual interest. Vary the design and articulation of each tower façade to respond to changes in solar orientation. When multiple towers are proposed, stagger tower heights to create visual interest within the skyline, mitigate 131 Figure 33: Conceptual “small sites” showing recommended minimum tower stepbacks from the base building and setbacks from side and rear property lines or centre line of an abutting lane. Figure 34: Adequate minimum tower separation distances, measured from closest building face to building face, protect access to sunlight and sky view for the surrounding public realm and neighbouring properties, and improve privacy and daylighting within tall buildings. 132 Figure 35: Minimum tower separation distance proportionate to building width, measured from building face to building face. wind, and improve access to sunlight and sky view. In general, variations of 5 storeys or more provides a difference in height that can be perceived at street level. Designs which reduce the appearance of the overall tower bulk and present a slender, point tower form in the skyline are encouraged. C.6 Pedestrian Realm C.6.1 Streetscape and Landscape Design Provide high-quality, sustainable streetscape and landscape design between the tall building and adjacent streets, parks, and open space. A well-designed and vibrant streetscape is vital to the character and quality of the tall building site and the surrounding public realm, as well as to the liveability of the city. Create a strong visual and physical connection between the building setback and public streetscape. Maintain universal access to public and shared entrances, particularly when there are changes in topography. On streets characterised by soft landscape setbacks or where ground floor uses require more privacy from the adjacent sidewalk, provide additional landscaping between the building face and public sidewalk. C.6.2 Sidewalk Zone Provide adequate space between the front of the building and adjacent street curbs to safely and comfortably accommodate pedestrian movement, streetscape elements, and activities related to the uses at grade. Along the primary street frontages of a tall building site, secure a sidewalk zone at least 6 m wide, as shown in Figure 36. Tall buildings at corners, transit nodes, on wider streets with higher and faster volumes of vehicular traffic, or other locations with significant pedestrian use, may require additional setbacks to accommodate pedestrian flow. Furthermore, tall buildings of significant height and density may require additional sidewalk width beyond 6 m to accommodate the anticipated volume of pedestrian traffic. 133 Figure 36: A generous sidewalk and strategic setback supports an active street frontage and vibrant pedestrian environment. C.6.3 Pedestrian Level Wind Effects Locate, orient, and design tall buildings to promote air circulation and natural ventilation, yet minimise adverse wind conditions on adjacent streets, parks, and open space, at building entrances, and in public and private outdoor amenity areas. While air circulation around tall buildings is important, down drafts from the buildings or accelerated winds from tunnelling between buildings can negatively affect pedestrian-level comfort and even become hazardous. In general, the taller the building, the stronger the potential for wind effects at the base and the greater the need for mitigation measures. The use of stepbacks at the tower base is a particularly useful strategy to dissipate down drafts. Landscaping and walls, as well as architectural devices such as projecting cornices, screens, terraces, overhangs, and permanent canopies can also be applied to reduce the effects of high speed wind around the base building and within rooftop amenity areas. A number of different scenarios and solutions to poor wind design are provided in Figure 37. 134 Figure 37: Issues and solutions to building wind design. 135 C.6.4 Pedestrian Weather Protection Ensure weather protection elements, such as overhangs and canopies, are well-integrated into building design, carefully designed and scaled to support the street, and positioned to maximise function and pedestrian comfort. The inclusion of pedestrian weather protection along the edges of buildings can greatly enhance the year-round enjoyment of streets and open space. Where base buildings form a continuous street wall, coordinated and uninterrupted weather protection allows pedestrians to move comfortably throughout the entire area in all seasons. Weather protection elements can work together with street trees to define and frame a street. They can help define building proportions at the street level, articulate entrances, animate base buildings, and enhance the character of a neighbourhood. Such protection is especially important at locations adjacent to transit stops and other areas with significant pedestrian flow. Provide permanent pedestrian weather protection, such as overhangs or canopies, at building entrances and along commercial and mixed-use street frontages. In general, locate weather protection at the top of the first floor (up to a maximum of 6 m above ground) and provide a width of 3 m projecting from the building. Translucent or opaque materials are recommended to mute reflections on ground floor glazing, mitigate passive solar gain, and reduce light trespass from the building interior. Colonnades are generally discouraged as weather protection devices, as they tend to pull retail frontages and associated pedestrian activity away from the street. Where they do prevail, design and space columns to maintain clear views to the uses behind, and promote ease of pedestrian flow. Provide generous proportions, including a minimum width of 3 m and minimum height of 6 m (1:2 ratio). C.7 Glossary • Articulation: The layout or pattern, expression and material character of building elements, including walls, doors, roofs, windows and decorative elements such as cornices and belt courses. • Point tower: A compact and slender tall building form with a typical residential tower floor plate of 750 square metres or less. • Setback: Horizontal distance measured at a right angle from any lot line to the nearest part of the main wall of a building or structure. • Stepback: The setting back of the upper storeys of a base building or of a tower from the face of a base building. • Streetscape: The distinguishing elements and character of a particular street as created by its width, degree of curvature, paving materials, design and placement of street furniture, trees, landscaping, lighting and other pedestrian amenities, as well as the setback and form of surrounding buildings. • Street Wall: The condition of enclosure along a street whereby the fronts of buildings align and the façades visually and physically join together to create a continuous defining edge for the street. 136 D Mid-Rise Building Guidelines The following section is derived from the City of Toronto’s Avenues and Mid-Rise Buildings Study, May 2010, including revisions from a 2016 City of Toronto Review of this study. An updated version of these guidelines is set to be published by late 2017. One general definition of mid-rise buildings used by the City of Toronto is “taller than a typical house or townhouse but no taller than the width of the street’s public right-of-way.” and not higher than 36 m (or 11 storeys). Note that these guidelines do not apply to base buildings (of tall buildings). D.1 Building Height The maximum allowable height of mid-rise buildings should be no taller than the width of the right-ofway, up to a maximum mid-rise height of 11 storeys (36 m). All buildings on arterials must achieve a minimum height of 10.5 m (3 storeys) at the street frontage, to make better use of existing infrastructure and prevent inefficient development as well as achieving minimum density for improved public transit. D.2 Front Façades D.2.1 Angular Plane The building envelope should allow for a minimum of five (5) hours of sunlight onto the main road sidewalks from spring to fall equinoxes.18 Specifically, mid-rises should allow for five (5) hours of sunlight access on the opposite sidewalk on east/west roads, and combined on both sides of the street for north/south roads (i.e. there must be sunlight on the sidewalks on both sides of the street, separately or at the same time, for 5 hours total). This minimum requirement also applies for diagonal streets, buildings set back from the property line, and streets that have a grade difference from one side to the other. D.2.2 Pedestrian Perception Stepback The minimum sunlight hours discussed above generally result in a stepback of the upper floors of mid-rise buildings. An additional stepback may be appropriate for buildings taller than 7 storeys (or 23 m) in height as a means of mitigating the pedestrian perception of height on the road. Above the maximum street wall, the building should have a stepback between 3 m to 5 m to achieve a clearly discernible top to the street wall and minimise shadow impact on the public realm. The minimum stepback dimension is 3 m. For roads 20 m or less in width, the stepback height should be at 10.5 m. For roads between 20 m to 36 m in width, stepback height should be at 13.5 m. For roads greater than 36 m in width, stepback height should be at 16.5 m. D.2.3 Alignment The front street wall of mid-rise buildings should be built to the front property lines or applicable setback lines. The street wall is defined as the portion of a buildings façade (frontage) comprised of the building base (minimum of 10.5 m or 3 storeys in height and up to the 80 % of the permitted maximum building 18 Or from fall to spring if you live upside down. 137 height). A mid-rise building should have a minimum of 75 %19 of its street wall built to the setback line, while the remaining 25 % may setback to a maximum additional distance of 5 m to provide a deeper area for lobby entrances, bike parking, or outdoor marketing areas such as café seating. At the ground floor level, any setback zone should be treated as an extension of the public realm in order to provide additional outdoor space and landscaping opportunities, allow for at-grade uses to expand outdoors, and to encourage street animation. This relationship of sidewalk to grade-related uses encourages diverse economic stimulation and social interaction at a pedestrian scale. D.3 Rear Transition Rear lanes such as local streets and service lanes are encouraged, with grade-related residential entrances facing existing low/medium density residential neighbourhoods where appropriate and possible. D.3.1 Rear Transition to Neighbourhoods: Deep Properties A deep property is defined depending on the width of the right-of-way. For a 20 m road, a deep lot is one 33 m or deeper. For a 27 m road, it’s 41 m; for a 30 m road, it’s 45 m; and for a 36 m road, it’s 52 m. The transition between a deep property and neighbourhoods, parks, open space areas, and natural areas to the rear, should be created through setback and angular plane provisions. This transition should include a minimum setback of 7.5 m to the building face and a 45° angular plane from the property line to a maximum height of 1:1. The 7.5 m setback allows for a two-way lane (6 m), and a walkway (1.5 m) or landscape buffer (1.5 m). This results in a lower building at the rear and a gradual transition from the rear property line. Where a public laneway abuts a site, the laneway may be included for the purposes of establishing the setback and angular plane, as shown in Figure 38. In order to minimise overlook, avoid windows closer than 10 m from the rear property line, and avoid balconies below 3 storeys from the rear property line. D.3.2 Rear Transition to Neighbourhoods: Shallow Properties A shallow property is one that isn’t defined as a deep property, as discussed above. All of the same standards discussed above apply for deep properties as for shallow properties, but for shallow properties the angular plane is taken from a height of 10.5 m (3 storeys) at the 7.5 m setback, instead of from the property line as for deep properties. The angular plane provisions for deep and shallow properties result in minimal shadow impacts on properties located behind a mid-rise building. Ideally, the minimum rear yard (or side yard) setback should be at least equivalent to the height of the nearest building on the site (e.g. house across the street). In situations where the rear of the property is at a different grade level than the mid-rise road frontages (e.g. the lane/property behind the mid-rise is elevated higher/lower than it), the rear angular plane should always be taken from the lowest grade elevation of the adjacent property located along the rear of 19 This may be incompatible with certain typologies which may be desirable in residential areas, e.g. courtyard-style buildings that open to the street. In such cases, context is important and the rules may vary. The general idea, however, is to make sure the building meshes with its surroundings. 138 Figure 38: Rear transition for deep properties abutting neighbourhoods, parks, open space, and natural areas (30 m right-of-way). the mid-rise building’s property line. This holds true for deep and shallow properties. This will ensure that properties to the rear aren’t subject to additional shadow impacts resulting from changes in grade, or creating potential for taller buildings adjacent to these shared property lines. D.3.3 Rear Transition to Employment Areas For industrial and office areas behind residential and/or mixed-use mid-rises, the requirements for privacy and sunlight aren’t as strict as they are for residential, mixed-use, parks, and open space areas. The transition in this case includes a minimum setback of 7.5 m from the property line to the building face to allow for a rear lane. At the setback line, the building height is permitted up to 13.5 m (or approximately four storeys). All floors above 13.5 m must step back an additional 2.5 m. This equates to a total setback of 10 m from the property line above a 13.5 m height. An example is shown in Figure 39. D.3.4 Rear Transition to Apartment Neighbourhoods A mid-rise building may be bounded along the rear by apartment(s), with the apartment building generally in one of three (3) configurations: 1. Parallel to the mid-rise’s rear property line with a setback used for parking and/or traffic; 2. Parallel to the mid-rise’s rear property line with a setback used for parks and/or open space; or 3. Perpendicular to the mid-rise’s rear property line with minimal to no windows facing the mid-rise. 139 Figure 39: Rear transition for properties abutting employment areas (30 m right-of-way). 140 There are three (3) main considerations that potential mid-rise properties should take into account: • Provide a minimum separation distance of 20 m between buildings, especially for those with facing windows. • Install attractive landscaping at the rear of the mid-rise, especially for those in Configuration 2. • Ensure the setback is consistent with the other rear transition requirements discussed in subsubsection D.3.1 and subsubsection D.3.2. For mid-rise buildings with Configuration 2 at the rear, the apartment building’s park/open space area must be treated as a public park/open space area and therefore follow guidelines listed in subsubsection D.3.2. Mid-rise stepbacks may start at higher heights than mandated in subsubsection D.3.2 for mid-rises with Configuration 1 at the rear, since the need for sunlight is less significant. For mid-rise buildings with Configuration 3 at the rear, a minimum separation distance of 15 m will suffice for apartment buildings 20 storeys or less, but should be higher for taller apartments. Note that guidelines in other sections still apply, e.g. shadow casting, ensuring 5 hours of sunlight, 7.5 m setbacks, etc. The guidelines discussed here are merely additional considerations to take into account when encountering Configurations 1–3. D.4 Corner Sites: Heights and Angular Planes On corner sites, the front angular plane and heights that apply to the right-of-way frontage will also apply to the secondary (side) street frontage. Exceptions to this condition may include key locations (e.g. where two major roads intersect) where design features should give prominence to the corner. At such major intersections, the widest right-of-way should be used to determine the stepbacks and heights that will apply to both frontages. Where this occurs, rear transition angular planes still apply. An example of a corner site mid-rise configuration is provided in Figure 40. D.5 Minimum Sidewalk Zones Right-of-ways between 20 m to 30 m inclusive should provide a minimum sidewalk width of 4.8 m. Right-of-ways between 31 m to 35 m inclusive should provide a minimum sidewalk width of 6 m. Rightof-ways 36 m or greater should provide a minimum sidewalk width of 7.5 m. Areas with busy transit stops, street corners and intersections, and other cluster areas of high pedestrian use require larger sidewalk widths. However, ‘sawtooth’ or uneven setbacks are anticipated in some areas as a temporary condition, and should be mitigated whenever possible. Note that these minimum sidewalk widths don’t include areas occupied by spaces such as cafés, and wider widths should be provided in those cases. D.6 Side Property Lines D.6.1 Continuous Street Walls A break in the continuity of the street wall and building fabric is disruptive to the success of the public function of the main road. For this reason, front yard parking, automotive uses, and buildings with large 141 Figure 40: Example of corner site conditions for mid-rise buildings. setbacks are detrimental in mixed-use and commercial areas. Mid-rise buildings should be built to the side property lines for at least the first 10.5 m of building height and up to a maximum of 6 storeys20 , to create continuous façades along the road and avoid blank side walls. The first 3 storeys should be continuous with the street wall, but the rest of the building above the street wall should have upper storey stepbacks and windows. Gaps between buildings, if any, should be minimal unless adjacent buildings have side windows (see subsubsection D.6.4). Note that a continuous street wall may not be required for, e.g., buildings adjacent to parks, open spaces, or heritage buildings. See the subsequent subsubsections for more details. D.6.2 Limiting Blank Side Walls Blank side wall conditions may be acceptable up to a height of 6 storeys if treated properly. However, large expanses of blank sidewalls should be avoided. To mitigate their impact, they should be designed with a material finish that complements the architectural character of the main building façade(s). D.6.3 Stepbacks at Upper Storeys There should be breaks at upper storeys between mid-rise buildings, providing sky-views and increased sunlight access to the sidewalk. This can be achieved through side stepbacks at the upper storeys, to avoid a “canyon effect” on the road. For mid-rises between 7 to 11 storeys, the following guidelines help avoid massive continuous 36 m-high slab-type buildings. Side stepbacks of a minimum of 5.5 m from the property line should be provided anywhere between 10.5 m (3 storeys) up to the building’s 80 % 20 Also see subsubsection D.2.2 and subsubsection D.6.3. 142 Figure 41: Diagram illustrating the side street setback. height to increase sky views and sunlight access to the sidewalk. Buildings that are 20 m (or 6 storeys) in height or less aren’t required to have upper storey side stepbacks. D.6.4 Existing Side Windows While minimising gaps between buildings is appropriate for most sites, this may not be desirable for some certain areas. This sometimes occurs where mixed-use areas abut an apartment complex adjacent to it on the road. New development must not negatively impact existing buildings with side windows. Where adjacent sites have walls with windows, a minimum of 5.5 m must exist between the windows and the adjacent building wall. D.6.5 Side Street Setbacks Where adjacent side street properties are low-scale residential with front yard setbacks, buildings should be setback along the side streets for a minimum 15 % of the side street lot frontage (lot depth) and range from a minimum of 2 m to a maximum of 5 m. This will help maintain views from the neighbourhood and create a gradual transition from the neighbourhood’s street to the main road. A visualisation of this setback is provided in Figure 41. D.7 Maximum Building Width Long façades at grade provide less interest and variation at the pedestrian level. At upper storeys, long, continuous façades prevent sunlight access and skyviews to the street. Where mid-rise building frontages are more than 60 m in width, building massing should be articulated or “broken up” to ensure that façades aren’t overly long. This can be accomplished by creating multiple buildings on wide sites, as well as by breaking up the façades through the use of vertical breaks and stepbacks. 143 D.8 Residential At-Grade Uses On certain main roads, it’s expected that limited portions may include residential uses at grade for the long-term. This is only appropriate where commercial uses aren’t likely to be viable. Townhouses aren’t appropriate on arterials and/or major roads, as it creates a privatised frontage which is difficult to convert to commercial uses in the future. Furthermore, townhouses don’t provide the minimal level of intensification desired for major roads. Ground floor residential units are encouraged to have their principal entrance from local streets where feasible. For mid-rise buildings with individual residential unit entrances along the main road, a minimum setback of 3 m is required beyond the 4.8 m or 6 m sidewalk zone that contains front steps (with the ground floor raised 1 m above grade), a raised planter, and porch/terrace area (similar to the townhouse guidelines). This is required to achieve an appropriate transition between public and private realms. For ground-level (i.e. not mixed-use) mid-rise residential buildings without individual unit entrances, this minimum setback is increased to 3.8 m and should contain a row of trees and a landscape buffer. D.9 Balconies and Projections As many units as possible should have balconies — it’s more family oriented, and encourages owner occupation and eyes on the street. However, neither projecting nor inset balconies on the front façade should be allowed on the 1st storey, and projecting balconies shouldn’t be allowed on the 2nd and 3rd storeys. Recessed, inset, and/or Juliet balconies between the 2nd and 3rd floors are permitted and encouraged. On the street-facing façade, projecting balconies shouldn’t be located within the Pedestrian Perception Stepback Zone (between 3–6 storeys), or below the first stepback. Within this portion of the building, recessed balconies inset behind the street wall, Juliet balconies, and terraces (as part of a stepback) are acceptable. However, a 0.5 m projection zone is permitted only if used to reinforce the sense of continuity of the street wall. Balconies on the rear façade should be setback a minimum of 10 m from the rear property line. Balconies, projections such as railings, and other permanent building elements shouldn’t encroach into the public right-of-way or setback, and should be contained within all angular planes. D.10 Roofs and Roofscapes Mechanical penthouses may exceed the maximum height limit by up to 5 m but must not penetrate any angular planes, as shown in Figure 42. Rooftop equipment and mechanical penthouses should be located within the specified right-of-way width to building height ratio. Placed this way, they’ll generally not be visible from adjacent sidewalks while minimally visible from the opposite sidewalk. However, as mechanical penthouses will be visible from adjacent properties, including neighbourhoods, they should be recessed, architecturally integrated, screened, and clad with materials that are complementary to the architecture of the building and the building façades. Portions of the roof not covered by mechanical penthouses should be developed as green roofs and/or usable outdoor amenity space. Examples include terraces and roof gardens, among others. If amenity 144 Figure 42: Mechanical penthouse placement within all angular planes. is provided on the rooftop, it should be screened with planters and/or setback to avoid overlook, and landscaped to promote comfortable use and shelter from wind and sun. Do not place habitable space (e.g. dwelling units) wrapping rooftop equipment and mechanical penthouses above the maximum allowable height. D.11 Prominent Sites Provide prominent architectural or landscape features (excluding signage) at the corners of sites or intersections to make them stand out from the building pattern along the rest of the block. On larger sites, articulate building mass to emphasise a sense of entry into a district or precinct or to distinguish one from another. D.12 Façade Design and Articulation The street wall should be designed to create a comfortable, yet highly animated, pedestrian environment through a rhythm of multiple retail frontages, architectural articulation, numerous entrances, display windows, canopies, and signage. The building should reinforce or establish a fine-grained retail character along the street wall, especially in districts where this is the characteristic. The ground floor should be articulated and highly transparent, with a minimum 60 % of this frontage to be transparent glass, in order to support a safe, accessible, and vibrant public realm. Utilities, vents, and other undesirable elements should be avoided on the lower levels of façades adjacent to the public realm. For larger buildings with shared pedestrian entries, entry should be through prominent entry lobbies or central courtyards facing the street. From the street, these entries and courtyards should provide visual interest, orientation, and a sense of invitation. 145 D.13 Parking, Servicing, and Vehicular Access Loading, servicing, garbage, on-site parking, and other vehicular-related functions shouldn’t detract from the use or attractiveness of the pedestrian realm. The main road should be pedestrian focused and therefore try to provide as uninterrupted of a pedestrian realm as possible. Ideally, these functions should be integrated within the interior of a building at the rear whenever possible, with vehicular access from a rear lane or local side street (and not from the arterial street). Locate waste and loading areas so that they aren’t visible from the public street. Where parking and service areas are located in courtyards, design buildings and landscape to minimise visual and noise impacts on outdoor spaces. Rear lanes should always exit onto adjacent side streets. Where feasible, incorporate shared driveways in order to reduce the extent of interruption to pedestrians. Consolidate vehicular entrances to serve multiple buildings within each block in order to minimise the number of interruptions in the street wall and to reduce the number of potential conflicts with pedestrians and cyclists. Prioritise pedestrian and cyclist circulation and connectivity with adjacent sites. Mid-block vehicular access should be avoided wherever possible. However, there are instances where this is the only point of access for certain sites. For mid-block sites without rear lane access, a front driveway may be permitted, provided established criteria are met, including: • The driveway is located as far from the adjacent intersection as possible, or a minimum of 30 m from the centre of the driveway to the centre of the nearest side street; • The access point is located away from areas where high pedestrian activities would occur; • Mutual access with adjacent properties is provided wherever possible; • Appropriate spacing between adjacent driveways is maintained resulting in no more than one driveway every 30 m; and • They should be contained within the building massing with additional floors built above the driveway. If a mid-block front driveway is built, a 6 m public lane must be provided at the rear of the property; this will form part of a continuous laneway system within the block as adjacent properties redevelop. As this redevelopment occurs, approved mid-block driveways should be designated for shared access to serve adjacent properties in lieu of, and until, a rear public laneway is established. Design any above-grade parking structures to reinforce the intended built character, and blend into the streetscape through façade treatments that conceal the parking levels and give the visual appearance of a multi-storey building. Façade design of above-grade parking structures should complement adjacent buildings in terms of openings, vertical articulation, materials, and colours. Pedestrian amenities such as awnings, canopies, and sheltered entries are encouraged. Locate pedestrian entrances for parking structures adjacent to main building entrances, public streets, or other highly visible locations. Locate exterior vehicular ramps and garage entrances to parking structures at the rear or side of buildings, away from main building frontages and streets. Avoid locating ramps/entrances at street corners or view termini. 146 D.14 Heritage Districts and Character Areas Mid-rise buildings must respect and be sensitively integrated with heritage buildings, and fit into the area’s local character. Impacts to the perception of the heritage properties or its prominence within an existing context should be minimised. Sightlines and views to identified landmarks shouldn’t be encroached upon by new developments. Cornice lines of adjacent buildings should be respected and followed, and use of building material similar to local buildings is encouraged. Additions to existing buildings are an alternative to redevelopment projects, and are encouraged in areas with an existing urban fabric. Additions shouldn’t exceed the overall maximum height for the site, and should be 50 % or less of the existing building height. Furthermore, additions should fit within the permitted envelope, i.e. meet all angular plane provisions and adhere to local façade articulation. D.15 Business and Commercial Parks The following suggestions may be helpful if you are building a business park area. Landscaping and architecture can help to anchor the overall image of the business park and create a sense of entry. Establish gateway features at the intersection of arterial streets with streets leading into the business park. Use landscaping and built form to create recognisable landmarks and community orienting focal points. Configure entry features to provide pedestrian access to the site. 147 Figure 43: Conserving local heritage with new building developments. E Townhouse and Low-rise Apartment Guidelines The following section is derived from the City of Toronto’s Townhouse and Low-rise Apartment Guidelines, February 2017. Note that much of these guidelines are identical to those listed in Appendix C, as they follow the same general outline, so identical text is replaced with a simple referral to the corresponding text in Appendix C. E.1 Site Context E.1.1 Heritage Locate and design buildings to conserve the cultural heritage values, attributes and character of on-site and adjacent heritage properties. In locations where proposed developments allow for appropriate conservation measures to be undertaken, heritage properties should be referenced to inform the scale and contextual treatment of the new development (as shown in Figure 43). When a proposed building is adjacent to a heritage property, design new buildings to respect the urban grain, scale, setbacks, proportions, visual relationships, topography, and materials of the historic context. If well-designed and appropriately sited, new development can make a positive contribution to a historic setting. Ensure that low-rise, multi-unit buildings don’t visually impede or have a physical impact on the setting of heritage properties. Adaptive re-use of heritage properties is encouraged. E.1.2 Building Types Employ a suitable building type (or types) to ensure that the new development fits well and responds appropriately to the particular site conditions, adjacencies and surrounding context. 148 Provide a less intense housing type as a transitional form adjacent to low scale residential neighbourhoods, parks and open spaces, or other less intensive uses. Use the appropriate building type to avoid: • Fronts of buildings facing rear yards or backs of buildings facing streets or parks; • Too many individual entrances on one façade; • Entrances not visible or with direct access from a street; • Parking lots located between a building and a street. On large sites, generally avoid a monotonous repetition of one type. Parking for street-related townhouses underground or at the rear of the building accessed via a lane or driveway is preferred. Townhouses with front driveways and garages should be avoided generally as they reduce front yard areas for landscaping and soil volume for tree growth. The garage doors present a face to the street lacking in animation and multiple curb cuts reduce pedestrian comfort and safety. Front integral garages should only be considered when no other option is technically feasible. E.2 Site Organisation E.2.1 Streets, Lanes, Mews, and Walkways Provide new streets, pedestrian mews, and walkways for safe, comfortable, and direct access for all new buildings. Design streets and lanes to be inviting. Create attractive and comfortable, pedestrian environments with landscaping including canopy trees, pedestrian-scale lighting, and other amenities. (For lanes, adapt streetscaping elements to fit within tighter dimensions). Provide through streets and lanes to minimise vehicle turnarounds, where possible. Locate access to sites on secondary streets, where possible, and consolidate driveway/laneway access points to minimise curb cuts. E.2.2 Shared Outdoor Amenity Areas Design shared outdoor amenity areas to be publicly accessible and a focal point within the development. Townhouses and low-rise, multi-unit buildings are popular with families with children and pets owners. Developments with well-designed and well-placed shared amenity areas with children’s play space, facilities for pets, and other shared elements like communal gardens, allow residents to experience and share in their collective property. Different types of open spaces are ideal for different densities and development sizes, and some are discussed in subsubsection C.3.4. High quality, centrally located, and sun-filled amenity spaces are focal points of communities. For projects including 20 units or more, where no or only some backyards are provided and for developments where 149 the site area is 1.0 ha or more, provide shared play space for children and other shared outdoor amenities as a focal point of the new development. Locate shared outdoor amenity area to maximise frontages on streets, mews and walkways to provide visibility and access. Locate and design amenity spaces for maximum access to sunlight. Complement and connect with open space on neighbouring properties, where possible. Locate parking, mechanical equipment and servicing areas away from amenity areas. Provide outdoor activity supports, such as seating and barbecues. E.2.3 Building Placement and Address Locate the buildings to frame the edges of streets, parks, and open space. Ensure that buildings fit harmoniously with the existing context and provide opportunities for high-quality landscaping and streetscaping. Maintain high visibility and direct access to front doors from the public sidewalk, especially when building entrances aren’t located on a public street. Design all building elevations that face streets, mews, parks and open spaces to appear and function as fronts, complete with porches/stoops, front doors and windows to activate the public realm. Provide greater building setbacks at strategic locations to avoid long, monotonous façades in order to improve pedestrian amenity and increased space for trees and other landscaping. Generally, provide breaks between buildings every 36 m. On corner sites, provide primary façades facing both streets and align the building to the setback pattern of neighbouring buildings on both streets. Setbacks allow for projecting elements such as porches, canopies, and landings. More information on setbacks can be found in subsubsection C.3.1 and subsubsection C.4.3. E.2.4 Site Services, Access, and Parking See subsubsection C.3.3. In addition: • Where surface parking is provided, the main parking area should be located within the interior of the site and to the rear and side of buildings. E.2.5 Priority Lots Use Priority Lots as gateways to the community, setting the look and feel of the interior neighbourhood. Ensure the community design incorporates priority lots including: gateway lots, corner lots, view terminus sites, windows street lots, and lots abutting parkland. Examples of such are shown in Figure 44. Gateway Lots are located along the main entrances to neighbourhoods from the external street system. As important markers or wayfinding devices for pedestrians, cyclists, and motorists travelling within and through a neighbourhood area, they are usually sited in conjunction with a landscaped community entry feature and should be designed to express the image and character of the community. Locate soft landscaping gateway features (such as planting, shrubs, etc.) within the public right-of-way. These features should be clustered and substantial enough to define the gateway site and street edge, requiring 150 Figure 44: Some examples of Priority Lots include: Gateway lots (G), Corner lots (C), and lots abutting Parkland (P). minimal maintenance. Plant material in the daylight triangle should be no taller than 0.5 m. Locate built or structural landscaped gateway features (such as architectural walls, ornamental fences, signage, etc.) within the gateway lot outside of the public right-of-way. Corner Lots play a significant role in setting the image, character and quality of the street and acting as landmark buildings within the neighbourhood. Treat both street-facing façades in a consistent manner with sufficient detailing to relate to the pedestrian scale at the street. Use architectural features such as wrap-around porches, doors, corner bays, gables, or bay windows to present a positive frontage to both streets, as well as to articulate and distinguish both façades. View Terminus sites occur at the top of a ‘T’ intersection (where one street terminates at a right angle to the other) as well as at street elbows. Dwellings on these sites are prominent in the streetscape as they terminate a view corridor and should be designed to provide visual interest (such as by incorporating significant architectural details and landscaping). For a pair of houses located at the end of a view corridor, locate driveways to the outside of the pair of dwellings to form a landscaped focal area. Window street lots front onto a local street parallel to an arterial/collector street but are separated from it by a boulevard or buffer. Due to the high degree of public visibility from major streets, dwellings on these lots have an impact on the overall character of the neighbourhood and should be designed to provide visual interest. Incorporate architectural features including a covered porch, portico, and large, well-proportioned windows. The main entrance to the dwelling should be oriented to face the window street. E.3 Building Design E.3.1 Fit and Transition See subsubsection C.2.1. 151 Figure 45: An example of how not to place townhouses. E.3.2 Facing Distances and Setbacks Locate and design buildings to ensure sunlight and sky views. Reduce overlook conditions between buildings and neighbouring properties. Adequate facing distances, setbacks and stepbacks between buildings assist in achieving desirable public/private amenity spaces on the development site and appropriate relationships to adjacent properties avoiding shadowing and overlook. For buildings less than 9.5 m in height (2–2.5 storeys), building faces should be separated at a minimum distance of 11 m. For buildings between 9.5 m to 11.5 m (3–3.5 storeys), this minimum distance is 13 m. For buildings taller than 11.5 m (3.5–4 storeys), this minimum distance is 15 m. Ensure that any additional height beyond the Main Building Face Height fits under a 45° angular plane originating from the top of the Main Building Face Height. Limit building element projections, such as balconies, into setback areas, streets, mews, and amenity areas to protect access to light and sky view. E.3.3 Primary Entrances Ensure well-designed front entrances and front yards. Enhance privacy for the resident, while maintaining “eyes on the street”. See subsubsection C.4.3. Avoid excessive projections such as stairs, porches, stoops, canopies, and private amenity spaces into pedestrian mews and front yard setbacks, as in Figure 45. For more suggestions on primary entrance placement, see subsubsection C.3.2. E.3.4 Private Outdoor Amenity Space Enhance the usability, comfort, and appearance of private outdoor amenity spaces within the public realm. 152 Figure 46: Private amenity spaces in townhouses. Note that “grade-related private amenity space” ≈ backyard. As shown in Figure 46, private amenity spaces can take a number of forms. Also see subsubsection C.3.5 for more information. The placement and design of balconies and terraces can have a major impact on the real and perceived bulk of a building. When poorly located and designed, these spaces can clutter the face of the building, shadow spaces below, and reduce privacy and sky view. Locate private outdoor amenity spaces for family-sized units so that they have views and access to outdoor play areas, where possible. Design private outdoor amenity spaces to mitigate impacts on the public realm and neighbours while maintaining direct access to sunlight and sky view. At-grade terraces shouldn’t compromise the public realm by “over-privatising” the area or preventing adequate landscaping in setback areas. Instead, they should maintain privacy for residents while beautifying the public realm, as shown in Figure 47. E.3.5 Building Relationship to Grade and Street Developments should relate directly to the existing or ‘natural’ grade and blend in with the topography of the surroundings. Raising development above the level of natural grade or the grade of abutting properties can create problematic conditions for adjacent properties, abutting streets and open spaces. These problems relate to issues of drainage, pedestrian access, and the quality of the public realm. Where it’s absolutely necessary to resolve grade differences, stepped landscaped terraces are the preferred solution. Maintain the existing grade at property lines. Design with existing grades on site and avoid artificially 153 Figure 47: Landscaping at the level of the raised terrace (backyard) and the sidewalk provide privacy for occupants on the terrace and an amenity for the public. raised or lowered grades. Limit the height of the stoop to the first floor to no more than approximately 3–5 steps and/or 1.2 m above the grade of the sidewalk directly at the front of the entrance, to avoid a long barrier-like flight of stairs up to the porch or stoop. Limit the height and use of retaining walls, particularly along street frontages, parks, open spaces, ravines and other areas of the public realm. Where retaining walls cannot be avoided, provide them in the form of low terraces with the total height not to exceed 1 m. Construct with attractive materials and incorporate extensive soft landscaping. E.4 Pedestrian Realm E.4.1 Streetscape, Landscape, and Stormwater Management Provide high-quality, sustainable streetscape and landscape between the building and adjacent streets, parks, and open space. Provide additional landscaping between the building face and public sidewalk on streets with soft landscape setbacks or where residential ground floor uses require more privacy from the adjacent sidewalk. Such treatment may include tree and shrub planting, minor grade changes, judicious use of railings, and lighting. Where landscaping may have an impact on motorist/pedestrian sightlines or movement, keep shrubs below 0.85 m in height and prune trees so that the lowest branches will be at least 2 m above ground level. Limit any other landscape features that might cause obstructions to a maximum height of 1 m. Where practical, use permeable paving to allow for water infiltration. E.4.2 Site Elements Well-designed site elements and the proper placement of utilities help to elevate the quality and experience of the public realm. Provide pedestrian-scaled lighting, such as bollards or lower-scale pole fixtures along pedestrian routes. Install appropriate lighting that is scaled to its purpose to avoid “over lighting”. Direct light downward 154 (with shielded fixtures, if necessary) to avoid light overspill onto adjacent properties, streets, and open spaces. Strive for vertical lighting along property lines to be 0 foot candles. E.4.3 Building Elements Ensure attention to the quality of architectural design, materials, building articulation, and placement of building and utility elements. Vary the design and articulation of each building façade to provide visual interest and respond to site conditions. Respect and reference built form pattern to help new buildings respect neighbourhood character. Provide variations in architectural design between building blocks for multiple block developments to create a different but cohesive collection of buildings. Ensure that roof elements don’t dominate the building particularly on larger buildings. House-form roofs, such as pitched or mansard roofs, aren’t appropriate for stacked and back-to-back townhouses or apartment buildings. Design rooftop amenity and privacy screening so as to not add to the overall height and mass of the building and minimise the visual impact of rooftop screens and rooftop accesses. E.4.4 Public Art See subsubsection C.3.7. E.5 Demonstration Plans and Case Studies Starting on the next page, demonstration plans provide 6 scenarios of how low-rise, multi-unit building types can be accommodated on different sites in different ways, such as surrounding a tall tower or within multiple blocks.

DRAFT ONLY It is possible for a building to employ an internal organization where single or multiple entrances are located fronting a public 158 street, which retains the rear of the site as shared or private outdoor amenity space and landscaped area. New apartment building development respects neighbourhood context by providing front For Discussion Purposes Only City of Toronto – JAN 2017 A key concern with Stacked and Back-to-Back Townhouses on shallow sites are the location of unit entrances. Individual unit entrances facing the rear yards of abutting properties are to be avoided due to the lack of visual connections to a public street, safety and way-finding concerns for residents and visitors. Locating entrances at the rear also creates atypical building relationships which are not desirable or consistent with Toronto's urban fabric. 59 DEMONSTRATION PLANS | TOWNHOUSE AND LOW-RISE APARTMENT GUIDELINES 6.2 DEEP MID-BLOCK SITE PublicPublic StreetStreet Building Type Shown: Hybrid Building 2 Other Possible Building Types: Existing Building 3 5 On Site Townhouse, Stacked Townhouse, Townhouse or Back-to-Back Townhouse, LowLow-Rise 1 Rise Apartment Building, and Primary Building Face Hybrid Building Pedestrian Connection Enhanced Landscape Area 4 4 Existing Building On Site Shared Amenity Space Townhouse or Low-Rise Outdoor Private Amenity Primary Building Face Tree Protection Area Pedestrian Connection Individual Unit Entrance Enhanced Landscape Area Shared Lobby Entrance Shared Amenity Space SELECTION OF GUIDELINES Parking Outdoor Private Amenity DRAFT ONLY For Discussion Purposes Only City of Toronto – JAN 2017 The selection of guidelines below is intended to highlight key aspects of each demonstration plan.

For Discussion Purposes Only City of Toronto – JAN 2017 In general, when the site is very deep and the travel distance required to access a unit entrance from a public street is greater than 6-8 units, consider the Low-Rise Apartment Building or Hybrid Building type. It is preferred for deep mid-block parcels to locate unit entrances on the public street frontage only and avoid entrances facing the side property line. In scenarios where access to units are located along the side, provide clear sightlines, lighting, pedestrian amenities, and landscaping to create a safe and comfortable pedestrian environment. 61 DEMONSTRATION PLANS | TOWNHOUSE AND LOW-RISE APARTMENT GUIDELINES 6.3 SITE ADJACENT TO OR WITH HERITAGE RESOURCE 3 Building Type Shown: Existing Building On Site Townhouse Public Street Townhouse or Low-Rise Existing Building On Site Townhouse or Low-Rise Other Possible Building Types: Primary Building Building Face Stacked Townhouse, Low-RisePrimary Face Pedestrian Apartment Building, and Hybrid Pedestrian Public Lane Building 2 1 Connection Connection Enhanced Landscape Area Shared Amenity Existing Building Space On Site Outdoor Private Townhouse or Amenity Low-Rise 2 4 Public Street Tree Protection Primary Building Area Face Individual Unit Pedestrian Entrance Connection Shared Lobby Enhanced Entrance Landscape Area Shared Amenity Parking Space Outdoor Private Amenity Public Park Enhanced Landscape Area Shared Amenity Space Outdoor Private Amenity Tree Protection Area Individual Unit Entrance Shared Lobby Entrance Parking Public Park Tree Protection Area SELECTION OF GUIDELINES Individual Unit The selection of guidelines below is intended to highlight key aspects of each demonstration plan.

For Discussion Purposes Only City of Toronto – JAN 2017 to form a distinctive character of their own, but too small to become their own neighbourhoods. Parcels with multiple building blocks should look at the site's configuration and neighbourhood character to identify the appropriate site organization, building type, and public realm design to strike a balance between fitting-in and creating a sense of place. Building types may vary throughout the development dependent on the location of the particular building block. Internal to the development site, buildings should have front to front facing relationships with adequate facing distance between blocks. 65 DEMONSTRATION PLANS | TOWNHOUSE AND LOW-RISE APARTMENT GUIDELINES 6.5 LARGE SITE WITH TOWER Public Street BuildingExisting TypeBuilding Shown: 1 Public Street 2 Primary Building Face Existing Building On Site Townhouse or Other Possible Building Types: 4 2 On Site Stacked and Back-to-Back Townhouse or Townhouse Low-Rise Low-Rise Pedestrian Townhouse, Stacked Townhouse, Connection Primary Building Face Back-to-Back Townhouse, LowEnhanced 3 Landscape Area Rise Apartment Building, and Pedestrian 5 Shared Amenity Hybrid Building Space Outdoor Private Amenity Building Existing On Site Tree Protection Area Townhouse or Low-Rise Individual Unit Entrance Primary Building Face Shared Lobby Entrance Pedestrian Public Street Shared Amenity Space Outdoor Private Amenity Tree Protection Area Individual Unit Entrance Enhanced Parking Landscape Area Shared Lobby Entrance Outdoor Private Amenity The selection of guidelines below is intended to highlight key aspects of each demonstration plan.

Continued on next page… DEMONSTRATION PLANS | TOWNHOUSE AND LOW-RISE APARTMENT GUIDELINES RATIONALE The "Tower in the Park" design concept was widely used in many parts of Toronto. These types of developments were often "Towers in the Parking Lots" instead and disrupted the pedestrian-oriented scale and character of many traditional Toronto neighbourhoods. When a tower site is appropriate for low-rise building infill, it is a priority for the redevelopment to rectify negative site conditions and improve connections to the surrounding neighbourhood. New low-rise development helps to improve existing negative site conditions and create new shared amenity areas for all residents. 166 DRAFT ONLY Every opportunity is made to eliminate under-utilized driveways and surface parking areas. Reorganizing the site may result in significant public realm improvements and can help to create more efficient and attractive site conditions. For Discussion Purposes Only City of Toronto – JAN 2017 In this demonstration plan, the new and existing buildings work together to frame streets and outdoor amenity spaces. Location of new buildings and open spaces consider the shadow impacts of the existing tower. Landscape areas throughout the site are improved to raise the overall quality of the property.

The organization of the building blocks on large sites is critical to creating a transition between existing and new communities. It is vital that new developments respect the positive characteristics of its context and further enhance these attributes to create a cohesive neighbourhood. Large blocks of townhouses can integrate well into established neighbourhoods by DRAFT ONLY enhancing pedestrian connections and positive characteristics of its context. Public parks and open spaces are central to each new neighbourhood and can be used as an organizational element for large sites. They are civic spaces and place making opportunities which can bring a community together. Public parks should be located centrally within easy access to the community with prominent public street frontage, access to 168 sky view and sunlight. Opportunities to expand public parks are encouraged. POPS can work together with existing open spaces to increase the possible activities and uses for the park. For Discussion Purposes Only City of Toronto – JAN 2017 Public streets are one of the fundamental building blocks to city building. On large sites, new public streets are often required to provide access. By aligning new streets to existing ones, they help stitch communities together. Public streets and pedestrian connections beyond the site should also be identified to protect opportunities for future extensions. 69 F Low-Rise Residential Buildings: Singles, Semis, and Duplexes The following section is derived from the Town of Richmond Hill’s Urban Design Guidelines, September 2013. Low-rise residential buildings generally range from 2 to 4 storeys and are typically built in wood frame construction. Low-rise residential may include singles, semis, duplexes, house-form apartments, walk-up apartments, or stacked townhouses. Access to units is either directly from the public sidewalk, a central lobby, a common corridor, or a shared courtyard. F.1 Frame the Public Realm Follow the guidelines discussed in subsection 10.1. In addition: • Organise low-rise residential buildings to frame the pedestrian realm and create an easily navigable walking environment. • Provide a minimum landscape setback between low-rise residential building and the public rightof-way, consistent with adjacent buildings. When there is an existing uniform front and/or side setback with adjacent properties, use a similar setback to fit within the existing streetscape. For new developments, design dwellings to frame the street edge with a consistent setback. • Front yard setbacks to the main building wall should range between 3 m to 4.5 m, and a minimum of 6 m to the garage wall. Side yard setbacks should be a minimum of 1.5 m, except where a rear yard garage is provided in which case one side setback should be a minimum of 3 m to accommodate the driveway. F.2 Ground Floor-to-Street Relationship Follow the guidelines discussed in subsection 10.2. In addition: • Raise the front door of ground-related residential units in a building by approximately 3–5 steps above the grade of the immediately abutting sidewalk, to ensure a clear distinction between the public and private realm. F.3 Sense of Entry Follow the guidelines discussed in subsection 10.3. In addition: • Clearly announce the primary pedestrian building entrance through the use of architectural treatments such as canopies, awnings, or double-height lobbies. • Orient building front entrances towards the street, and incorporate special architectural features such as porches or landscaping to emphasise the prominence of the front entrance. 169 • Provide weather protection to pedestrians at the main entrance through the use of a covered porch, portico, canopy, or recess. Porches, articulated rooflines, landscaping, and colour orient the pedestrian towards the main entrance. • Provide a clear and unobstructed pedestrian walkway from the sidewalk to the front door. • Provide pathways between residential areas and non-residential sites that directly and clearly connect these areas. F.4 Integrate Urban Open Space Follow the guidelines discussed in subsection 10.4. F.5 Light, View, Skyline, and Privacy Follow the guidelines discussed in subsection 10.5. In addition: • Stepbacks of 2 m are required above the 3rd storey. • Place lighting at each entrance to the dwelling, and provide a minimum of 1 light fixture per garage door. Lighting fixtures should complement the architectural style of the dwelling. • Lighting should be downcast to minimise light pollution and avoid spillover onto adjacent properties. • Windows facing interior side yards should be kept to a minimum to ensure privacy. F.6 Prominent Sites Follow the guidelines discussed in subsection 10.6. F.7 Priority Lots Use Priority Lots as gateways to the community, setting the look and feel of the interior neighbourhood. Follow the guidelines discussed in subsubsection E.2.5 for Gateway, Corner, View Terminus, and Window Street Lots. F.8 Scale Transition Follow the guidelines discussed in subsection 10.7. In addition: • Buildings should relate to the scale and height of adjacent low-rise buildings to maintain a wellproportioned street elevation. • Create a transition in building heights if the new development is higher or lower than existing buildings. Avoid abrupt variations in building massing, height, and size of adjacent structures, as shown in Figure 48. 170 Figure 48: Building height should remain relatively constant with gentle transitions. Abrupt variations in height should be avoided. • Design bungalows with raised front façades, steeper roof pitches, and increased roof massing to provide for better transition with any adjacent 2-storey dwellings. F.9 Façade Treatment Follow the guidelines discussed in subsection 10.8. In addition: • Articulate the elevation of units through the use of material, colour and architectural elements in a manner that provides variation between dwelling units, but reinforces common characteristics that visually unites the block. • Locating identical building elevations side by side or directly opposite on the same street is strongly discouraged. Buildings with identical front elevations should be separated by a minimum of two (2) buildings having different elevations. • Design street-facing garages so that they aren’t the dominant feature in the streetscape. Encourage the use of upgraded garage door styles, including integrated glazing and other architectural details. • Provide a variety of roof configurations in order to provide visual interest along a streetscape. F.10 Building Projections Follow the guidelines discussed in subsection 10.9. In addition: • Projections and encroachments such as porches, bay windows, canopies, and stairs into the front yard are encouraged to add visual interest along the streetscape. 171 • For the side of a low-rise building with frontage on a main street, only a very small projection zone is permitted to reinforce the sense of continuity of the street wall. • For the side of a low-rise building that fronts on a local or residential street, a larger projection zone from the principal street wall face is permitted. F.11 Vehicular and Pedestrian Circulation Incorporate garages oriented towards the front of the dwelling into the main massing of the building. Recess garages to ensure they are flush with the main building face. Garages that are detached from the main dwelling unit in the front yard are not permitted. Driveway widths should be no wider then the garages they serve. Locate driveways away from parks, open space features, public walkways, schools, and intersections. Reverse sloping driveways (that slope down from the curb to the garage) are discouraged. Permeable paving for driveways is preferred. Driveways should be paired where possible. F.12 Vehicular and Pedestrian Circulation Follow the guidelines discussed in subsection 10.10. In addition: • Driveway widths should be no wider then the garages they serve. Locate driveways away from parks, open space features, public walkways, schools, and intersections. Reverse sloping driveways (that slope down from the curb to the garage) are discouraged. Driveways should be paired where possible. F.12.1 Pedestrian Connections Follow the guidelines discussed in subsubsection 10.10.1. F.12.2 Service and Loading Areas Follow the guidelines discussed in subsubsection 10.10.2 for hiding utilities. F.12.3 Parking Follow the guidelines discussed in subsubsection 10.10.3. In addition: • Where a rear lane is provided, site garages at the rear of the lot and where possible, pair rear lane garages to allow for an increased rear yard. Design rear lane garages to be complimentary to the main dwelling. Site rear yard garages as close as possible to the minimum setbacks in order to maximise the rear yard amenity area. Design rear yard garages to be complementary to the main dwelling. • Side-facing garages in front of a dwelling are generally discouraged. They may be permitted on lots three (3) units wide or greater, provided that: – The lot isn’t a corner lot; 172 – The wall of the garage facing the street exhibits a high level of design variety, including windows and detailing consistent with the rest of the dwelling; – Dwellings of this nature are sited in pairs with garages located to the outside of the pair in order to create a courtyard effect between the dwellings; – Main entry stairs into the dwelling are designed so as to not interfere with vehicular access to the garage; and – Garage doors are setback a minimum of 7.5 m from the side lot line. • Incorporate garages oriented towards the front of the dwelling into the main massing of the building. Recess garages to ensure they are flush with the main building face. Garages that are detached from the main dwelling unit in the front yard are not permitted. 173 G Neighbourhood Plazas and Large Format Retail The following section is derived from the Town of Richmond Hill’s Urban Design Guidelines, September 2013. Neighbourhood plazas are small-scaled shopping areas. The primary clientele of neighbourhood plazas are nearby residents. They often include a pharmacy or restaurant as the anchor, with other smaller convenience commercial retail uses. Elements of a well-designed neighbourhood plaza include a unifying site design, common architectural treatment, convenient pedestrian connections within the site and to the adjacent residential neighbourhood, and sufficient on-site parking. It must fit within and respect the scale of the neighbourhood, orient to the pedestrian, and encourage people to get out of their cars to enjoy the pedestrian environment within the neighbourhood. Large format retail supports a larger trade area and is generally part of a more comprehensive commercial shopping centre development. The following guidelines support both types of commercial centres. G.1 Frame the Public Realm Follow the guidelines discussed in subsection 10.1. In addition: • Orient buildings to place the longest side towards the primary street frontage. • Organise buildings to frame the pedestrian realm and create an easily navigable walking environment. • Locate pedestrian entrances towards the primary street frontage. Provide direct pedestrian access from public sidewalk to building entrances. • Organise sites to attract future infill development. Introduce an internal street-and-block pattern into large sites, to facilitate intensification over time in an urban way, as shown in Figure 49. G.2 Ground Floor-to-Street Relationship Follow the guidelines discussed in subsection 10.2. In addition: • Reduce the scale of blank walls through fenestration, canopies, arcades, and other architectural techniques. G.3 Sense of Entry Follow the guidelines discussed in subsection 10.3. In addition: • At the ground floor level, any setback zone shall be treated as an extension of the public realm, to provide additional outdoor space, allow for at-grade uses to expand outdoors, and to encourage street animation. 174 Figure 49: Basing new development on an internal street and block pattern can accommodate future infill development. 175 • Clearly announce the primary pedestrian building entrance through the use of architectural treatments such as canopies or awnings. • Use tree planting, soft landscaping, street furniture, and surfacing material to define, improve, and reinforce pedestrian routes. • Provide pathways between residential areas and neighbourhood plazas that directly and clearly connect these areas. G.4 Integrate Urban Open Space Follow the guidelines discussed in subsection 10.4. In addition: • Encourage the development of courtyards and publicly-accessible open spaces visible from the public realm at ground level. Where feasible, design these open spaces in relation to local serving retail uses such as cafés and to the public open space network. G.5 Light, View, Skyline, and Privacy Follow the guidelines discussed in subsection 10.5. In addition: • The minimum neighbourhood scale commercial building height is two (2) storeys; upper stories could include other office commercial and professional uses. • Single storey commercial buildings should approximate a minimum 2-storey building height. This could be accomplished through a single-storey building with parapet or a double height ground floor. G.6 Prominent Sites Follow the guidelines discussed in subsection 10.6. G.7 Scale Transition Follow the guidelines discussed in subsection 10.7. In addition: • To ensure that light, view, and privacy is maintained for adjacent low density or medium density residential neighbourhoods, design new development to incorporate transitional zones consisting of: – A minimum rear yard or side yard setback, measured from the boundary of the adjacent low density or medium density residential area, equivalent to the height of the nearest building on the site, and – New local streets or service lanes facing existing low density or medium residential neighbourhoods where appropriate and possible. • 3 m street wall stepbacks are required above three (3) storeys. 176 G.8 Façade Treatment Follow the guidelines discussed in subsection 10.8. G.9 Building Projections Follow the guidelines discussed in subsection 10.9. In addition: • Entrance canopies, awnings, and signage should be appropriately scaled, attractive, and integrated into the architecture of the building to contribute a positive vibrancy to the public realm. • For the side of a large format retail building with frontage on a main street, a 0.5 m projection zone is permitted to reinforce the sense of continuity of the street wall. • For the side of a large format retail building that fronts on a local or residential street, a 2 m projection zone from the principal street wall face is permitted. G.10 Vehicular and Pedestrian Circulation Follow the guidelines discussed in subsection 10.10. G.10.1 Pedestrian Connections Follow the guidelines discussed in subsubsection 10.10.1. In addition: • Prioritise pedestrian and cyclist circulation and connectivity with adjacent sites. • An internal network of clearly designated, appealingly landscaped, and well-lit pedestrian walkways should be provided to traverse routes between parking areas, building entrances, and public streets. G.10.2 Service and Loading Areas Follow the guidelines discussed in subsubsection 10.10.2. G.10.3 Parking Follow the guidelines discussed in subsubsection 10.10.3. In addition: • Surface parking lots must not consume more than 40 % of the primary street frontage. Where surface parking is provided, the main parking area should be located within the interior of the site and to the rear and side of buildings. • Arrange parking spaces to minimise the number of traffic aisles that pedestrians arriving by vehicle must cross in order to move between parking and building entrance. 177 H Institutional Buildings The following section is derived from the Town of Richmond Hill’s Urban Design Guidelines, September 2013. Institutional buildings — including schools, places of worship, hospitals, police stations, fire halls, transit buildings, community centres and other civic edifices — help to define the city’s civic identity and should stand out from other buildings. H.1 Frame the Public Realm Follow the guidelines discussed in subsection 10.1. In addition: • Institutional buildings should be architecturally distinct from the surrounding urban fabric. • Locate institutional buildings on prominent sites to reinforce community identity and terminate important views where possible. • Institutional buildings should frame streets and public open spaces. Organise institutional buildings to frame the pedestrian realm and create an easily navigable walking environment. • Orient buildings with elongated floor plates with the longest side towards the primary street frontage. • Locate pedestrian entrances towards the primary street frontage. Provide direct pedestrian access from the public sidewalk to building entrances. H.2 Ground Floor-to-Street Relationship Follow the guidelines discussed in subsection 10.2. In addition: • Reduce the scale of blank walls through fenestration, canopies, arcades, and other architectural techniques. H.3 Sense of Entry Follow the guidelines discussed in subsection 10.3. In addition: • At the ground floor level, any setback zone shall be treated as an extension of the public realm, to provide additional outdoor space, allow for at-grade uses to expand outdoors, and to encourage street animation. • Ground floors for institutional uses shall be universally accessible, articulated to respond to human scale, and provide good visual connection between interior spaces and the public realm. 178 • Clearly announce the primary pedestrian building entrance through the use of architectural treatments such as canopies, awnings, or double-height lobbies. Primary entrances should face the frontage street, be easily accessible from the sidewalk and provide legible connections between the public realm and interior circulation spaces. • Use tree planting, soft landscaping, street furniture, and surfacing material to define, improve, and reinforce pedestrian routes. • Provide pathways between residential areas and institutional/civic areas that directly and clearly connect these areas. H.4 Integrate Urban Open Space Follow the guidelines discussed in subsection 10.4. In addition: • Encourage the development of publicly-accessible outdoor open spaces at ground level, as well as rooftop gardens and green roofs. H.5 Light, View, Skyline, and Privacy Follow the guidelines discussed in subsection 10.5. H.6 Prominent Sites Follow the guidelines discussed in subsection 10.6. In addition: • Locate institutional buildings toward key intersections to emphasise their civic importance and shape the pedestrian realm at corners. • Provide significant architectural or landscape features at the corners of sites or intersections to make institutional buildings stand out from the built form pattern along the rest of the block. H.7 Scale Transition Follow the guidelines discussed in subsection 10.7. In addition: • 3 m street wall stepbacks are required for institutional buildings above three (3) storeys. H.8 Façade Treatment Follow the guidelines discussed in subsection 10.8. 179 H.9 Building Projections Follow the guidelines discussed in subsection 10.9. In addition: • Entrance canopies, awnings, and signage should be appropriately scaled, attractive, and integrated into the architecture of the building to contribute a positive vibrancy to the public realm. • For the side of a large format retail building with frontage on a main street, a 0.5 m projection zone is permitted to reinforce the sense of continuity of the street wall. • For the side of a large format retail building that fronts on a local or residential street, a 2 m projection zone from the principal street wall face is permitted. H.10 Vehicular and Pedestrian Circulation Follow the guidelines discussed in subsection 10.10. In addition: • Where feasible, incorporate shared driveways in order to reduce the extent of interruption to pedestrians. Where vehicular access is only feasible from arterial streets, a front driveway may be permitted, provided that mutual access with adjacent properties are provided wherever possible, and that the access point is located away from areas where high pedestrian activities would occur. H.10.1 Pedestrian Connections Follow the guidelines discussed in subsubsection 10.10.1. In addition: • Prioritise pedestrian and cyclist circulation and connectivity with adjacent sites. H.10.2 Service and Loading Areas Follow the guidelines discussed in subsubsection 10.10.2. In addition: • Avoid areas where high pedestrian traffic is expected by directing vehicular access to loading and servicing facilities to collector or local streets and rear lanes, not from the arterial street, and to the rear or side of the building. H.10.3 Parking Follow the guidelines discussed in subsubsection 10.10.3. In addition: • Where surface parking is provided, the main parking area should be located within the interior of the site and to the rear and side of buildings. Surface parking is prohibited between the building and sidewalk. • Avoid areas where high pedestrian traffic is expected by directing vehicular access to parking facilities to collector or local streets and rear lanes, not from the arterial street, and to the rear or side of the building. 180 • Locate exterior vehicular ramps and garage entrances to parking structures at the rear or side of buildings, away from main building frontages and streets. Avoid locating ramps/entrances at street corners or view termini. • Locate pedestrian entrances for above-grade and below-grade parking structures (i.e., not including surface parking lots) adjacent to main building entrances, public streets, or other highly visible locations. • Design above-grade parking structures to reinforce the intended built character, and blend into the streetscape through façade treatments that conceal the parking levels and give the visual appearance of a multi-storey building. • Façade design of above-grade parking structures should complement adjacent buildings in terms of openings, vertical articulation, materials, and colours. Pedestrian amenities such as awnings, canopies, and sheltered entries are encouraged. H.10.4 Drop-off Areas Organise drop-off areas into the side or rear of the side. When located at the rear, provide direct visual and physical pedestrian access to the street frontage. Provide taxi stands and bus drop-off areas. Passenger drop-off areas (from private cars) should include the following elements: • Drop-off access should be from rear lanes or secondary streets wherever possible. Avoid placing drop-off areas at highly visible locations, such as street termini. • Pedestrian connections should lead directly from drop-off areas to the front entry of the building. Provide weather protection for outdoor waiting areas, to make getting to and from the site more comfortable. • Design drop-off areas to be pedestrian-oriented, minimise conflicts with pedestrian routes, and to include decorative paving material, textures, or colours to emphasise pedestrian connections. H.11 Community Service Location and Shared Facility Use Locate community facilities such as schools, libraries, and community centres to be focal points for the community, and where possible, to create new terminus views. Ensure community facilities are well-landscaped and visible at the pedestrian level, in recognition of their prominent locations. Locate community facilities in close proximity to transit facilities and routes. Co-locate community services and integrate facilities with new development to ensure shared use as well as efficient, inclusive, and dynamic program delivery. Locate compatible community buildings in close proximity or in the same building or on the same site to promote visibility, maintain community focus, and ensure efficient use of land and building resources. The co-location of services and facilities can minimise trips and travel time, and address a family’s daily 181 needs through various stages of life. Co-location supports interaction between people of differing backgrounds, ages, and socio-economic conditions. Maximising resources by grouping services in the same facility improves public access. Shared use of multi-service facilities strengthens communities, improves public health, and achieves positive socio-economic outcomes. One example is to co-locate an elementary school, high school, neighbourhood centre, and child care centre to share resources. A playground or playing field used by school children could be adjacent to a park open to the public. Seniors centres can also host child care centres, or having the seniors centre overlook the children’s courtyard, with seniors watching children playing. Local libraries can be located within the same building as schools. 182 I Planning for Children in New Vertical Communities The following section is derived from the City of Toronto’s Growing Up: Planning for Children in New Vertical Communities, May 2017. I.1 Whimsy and Design for Four Seasons Incorporate whimsical elements and design for year round enjoyment. Whimsical forms can become way-finding elements and help orient children by creating a sense of place, inclusivity, and a feeling of belonging. Encourage a sense of joy and playfulness by incorporating whimsy in public art, building design, streetscapes, street furniture, and parks and open space features. Design child-friendly elements at a scale that responds to children, that provokes the imagination, and are fun, interactive, educational, musical, and brightly coloured in fantastic sculptural forms. Design for four seasons should be transformable, such as a walking trail that becomes a skating trail in the winter; incorporate animated patterns, colour, and light; and flexible for year-round use and events. I.2 Building Configuration Provide a critical mass of large units primarily located in lower portions of the building. Increasing the number of large units creates a sense of community within the building. Units in lower portions of the building can have direct access to the outdoors (including rooftop amenity space) while reducing dependency on corridors and elevators. Children playing outdoors can be more easily supervised from the units above. At-grade units should provide direct access to amenity, local streets, or laneways for convenience. I.3 Common Indoor and Outdoor Amenity Provide indoor and outdoor amenity spaces to support a variety of age groups and activities. Design a portion of amenity space for children and youth. Flexible-use space can be included in that area. The proportion should relate to the number of large units in the building (ideally, at least 25 %). Locate and protect outdoor amenity space from shadow and wind impacts of existing and future development. Enable passive supervision by locating child-specific amenities adjacent to other amenities. Outdoor amenity space designed for children and youth should be: • Directly accessible from private terraces if located on the same level; and • Could include hardy landscape planting for flexible outdoor play, but this should not be counted towards more than 25 % of the outdoor amenity area. 183 When planning a site with multiple buildings, consider grouping a portion of the amenity in a shared complex. Consider the community-building potential of food by providing indoor/outdoor furniture to enable communal meals and gathering, as well as by providing roof-top gardening opportunities. 184 J Parks The following section is derived from the Town of Richmond Hill’s Urban Design Guidelines, September 2013. J.1 Parks and Open Spaces: Access and Type Provide a variety of types of parks and open spaces that are easily accessible and meet a range of needs. A 400 m radius is the rough comfortable walking distance with a child. A child’s mobility is determined by age; thus, distances are experienced differently. Parks and open spaces are most accessible when located close to home and on safe routes, allowing children to exercise independent mobility. New parks and open spaces should be convenient and centrally located to meet daily needs within 250 m to 500 m, or 5–10 minute walking distance of a new development site. Where feasible, locate new parks and open spaces on safe routes and minimise the number of intersections children need to cross to access them. Pursue opportunities to re-purpose underutilised spaces such as surface parking lots, left-over land parcels, and redundant vehicular lanes through “road diets”. Park design should consider a range of elements that are flexible and specific to allow for a diversity of activities, resting, climbing, and imaginative/adventure/nature play to suit all ages and abilities. Provide a combination of: 1. Specific elements including: play equipment for a broad range of age groups, sandboxes, water features, play courts, and smaller skateboard features; and 2. Flexible elements including: large boulders, lawn areas, mounds, concrete or stone shapes, and seat walls. These elements could be sculptural and whimsical. Where feasible, provide dog amenities to prevent conflicts with children and minimise damage to the public realm. Playgrounds should: 1. Be located safely within parks and away from streets; 2. Offer group seating and gathering space for caregivers to allow for formal and/or informal supervision; 3. Provide entry/exit points that include integrated physical barriers to prevent young children from running into the street, such as fences, low walls, or maze-like offsets; and 4. Include naturalised spaces for children to explore. 185 J.2 All Parks Parks should be designed as a focal point for neighbourhoods, and should be centrally located, preferably on a corner of two public streets wherever possible. The location of the parks should avoid major grade changes in active areas. Front buildings to overlook public spaces, especially for playgrounds which should be highly visible to public streets and/or houses to enhance safety. Provide a mix of activity for constant use of the space. Highly visible parks should form a linked network, in order to provide a variety of safe recreation and movement options between neighbourhoods and centres and corridors. Park entrance design should be clearly defined using landscaping and architectural elements, and should provide amenities including pedestrian-scale lighting and signage visible from surrounding streets, to assist in orientation and use of park amenities. Vehicular connections through parkland should be limited to emergency and maintenance vehicle routes, and access to major park facilities and parking areas. Highly visible connections should link the major park amenities and facilities through walkways and bike paths. Parks should be located to serve the diverse needs of the community, including facilities for passive recreation (e.g. walking trails, community gardens, seating areas, park pavilions, interpretive displays, public art) and active recreation (e.g. sports fields, skating rinks, bike paths). Seating and shade areas should be designed in coordination with pathways and play area locations. A greenway system is comprised of connected, uninterrupted, and undisturbed wild areas such as a forest. J.3 Community Parks Community Parks should have frontage on an arterial or collector street. Where appropriate, houses should front onto Community Parks on single-loaded streets to emphasise passive security or “eyes on the park” and to frame the park through the creation of built form edge. Community Parks, community centres, and libraries should be co-located and share parking in order to reduce the land required for surface parking lots. J.4 Neighbourhood Parks Neighbourhood Parks should have frontage on a collector or local street, and where possible, at the terminus of T-intersection streets and open crescents, to create an attractive public realm and enhance safety through casual surveillance. Neighbourhood Parks may be directly connected to school sites to encourage mutual use of outdoor facilities. Development should be designed to front onto the Neighbourhood Park wherever possible. Where residential side or rear yards abut a Neighbourhood Park, fencing and landscaping should be provided to demarcate the public and private realm. On-street parking along public streets is encouraged adjacent to the park. 186 Figure 50: This Vista Block provides a lookout over the Greenway System and includes plantings and a paved seating area. J.5 Urban Squares Urban Squares should be open to the public and accessible at all times, without physical barriers or gates. To ensure usage and presence, the square should be fronted by animated uses with a consistent building setback and a high level of transparency. These would be high pedestrian areas such as restaurants and cafés, preferably with some outdoor seating areas. Consider extending the paving treatment onto the street to give the space further prominence. This additional area would delineate an extended space that could be occasionally used for large-scale events, such as a farmers market or festival. J.6 Vista Blocks Incorporate Vista Blocks (an example of which is shown in Figure 50) along the edges of your city’s Greenway System, stormwater management facilities, parks, and urban open spaces to provide views to these features. Provide amenities within Vista Blocks (e.g. resting spots, pedestrian walkways, lookout sites) as appropriate. Locate Vista Blocks along publicly accessible lands, to ensure maximum visibility and public accessibility to the feature being framed. Incorporate design elements that are unique to their location within the neighbourhood, and which are coordinated with other structural elements. Large groupings of native shrub, grass, and wildflower species are encouraged to create visual interest, frame the view, and minimise maintenance requirements. J.7 Nature Parks and Trails Provide direct connections between cycling routes along streets and trails within your city’s Greenway System. Trail design should reflect the function and nature of the type of open space it occupies. Trail widths should allow for two-way cyclist or pedestrian passage (e.g. multi-use trail designs). Nature trails should include multiple access points, and be accessible and visible from the public street or other public areas. Where appropriate, provide access points every 250 m for safety and maintenance purposes. Design access points to be barrier free. Include adequate amenities such as seating, trash receptacles, 187 lighting, and signage. Use low-impact materials that are porous and stable. Lighting levels on trails should be individually determined, particularly where lighting may disturb adjacent residences and natural habitats. 188 K Effective Lighting The following section is derived from the City of Toronto’s Best Practices for Effective Lighting, June 2017. Poor lighting has multiple negative impacts on human physical and mental health, and contributes to light pollution. K.1 Lighting for Safety and Security The goal of security lighting is to discourage criminal activity by creating an environment where such activity may be readily and accurately observed. Poorly designed security lighting actually has the opposite effect: the glare of an unshielded lamp blinds an observer and affects dark adaptation, making it difficult to see into shadows. Security lighting is a major source of glare and overlighting. It’s not evident that increased lighting decreases crime. Studies have shown that criminal activity and vandalism actually increase with increased lighting. Most burglaries occur during daylight hours. Our city becomes safer when more people use public spaces at night. Well-designed public lighting creates an inviting environment for the use of public spaces. To create an attractive streetscape, priority should be given to uniformity of lighting that is used in conjunction with security cameras. Avoid poorly placed lights that create blind-spots for potential observers and miss critical areas. Ensure potential problem areas are well lit: pathways, stairs, entrances/exits, parking areas, ATMs, phone kiosks, mailboxes, bus stops, children’s play areas, recreation areas, pools, laundry rooms, storage areas, dumpster and recycling areas, etc. Avoid overly bright security lighting that creates blinding glare and/or deep shadows, hindering the view for potential observers. Eyes adapt to night lighting and have difficulty adjusting to severe lighting disparities. Place lighting along pathways and other pedestrian-use areas at proper heights for lighting the faces of the people in the space (and to identify the faces of potential attackers). Only light areas where needed, i.e. parking spaces versus parking aisles. K.2 External Lighting Fixtures Eliminate direct upward light, which is projected directly upward by inefficient lighting fixtures. Preferred fixtures direct light downward to the surface where it’s needed. They minimise uplight which causes skyglow and glare to an observer. Examples are shown in Figure 51. Do not use lighting fixtures that shine light horizontally or upwards; light should only be directed downwards. Ensure that all lighting is shielded and pointed so that it shines downward onto the ground rather than into a person’s eyes. All lighting should be facing downward on building façades. Shield street facing lighting so that establishments and the sidewalks can be seen by passers-by. Where external lighting of a building is necessary, use downlight to highlight architectural features. Pathways can be illuminated by passive fluorescent pads, parking lots should rely on car headlights for lighting, and signage and buildings should be illuminated only when absolutely necessary. The intrusion of light from nearby streets, businesses and residences should be strictly controlled. 189 (a) Effective external lighting. (b) Ineffective external lighting. Figure 51: Differences between effective and ineffective external lighting. Lamps that emit light horizontally and/or upwards should be avoided. Full cut-off street lighting is designed to direct the light where it’s needed – to the roadway and sidewalk surfaces. This minimises the waste light that causes sky glow and lessens glare by shielding the viewer from a direct view of the light source. On low-speed residential streets, it may be sufficient to provide lighting for sidewalks and rely on car headlights for lighting the roadway. On low-speed residential streets, it may be sufficient to provide lighting for sidewalks and rely on car headlights for lighting the roadway. Street lighting shouldn’t be used to illuminate adjacent surfaces such as residential lawns and walkways. In order to avoid light trespass onto adjacent properties, the pole height for parking lot lights should be no higher than the buildings or trees around the perimeter of the parking lot. The luminaries may require shielding to control light spill. Parking lot lighting shouldn’t be used to promote a business or illuminate a building façade. 190 L Green Parking Lot Design The following section is derived from the City of Toronto’s Design Guidelines for “Greening” Surface Parking Lots, January 2013. L.1 Location and Layout L.1.1 General Requirements a. Locate surface parking behind or beside buildings, away from primary street frontages and street corners. Parking shouldn’t be located between the front façade line of buildings and a street edge. b. Where possible, to reduce potential vehicle and pedestrian conflicts related to cars moving in/out of parking spaces, avoid locating parking along major drive aisles, street access driveways, or in front of building entrances and service areas. c. Position parking rows perpendicular to the main building entrance(s) to assist safe pedestrian movement toward the building. d. Divide larger parking areas both visually and functionally into smaller parking courts. Limit the length of parking rows to a maximum of 60 m (20–23 contiguous spaces). Longer rows should include landscaped breaks, such as islands, with shade trees. e. Use landscaped islands and medians for separation. Exceptions might include parking lots on small/narrow sites, or disabled parking and short-term loading spaces where proximity to building entrances is important. f. Integrate bicycle parking, shopping cart corrals, ticket or payment kiosks, signage, public art, and other applicable site elements into the design and layout of the parking lot. L.1.2 Site Grading a. Ensure that any grade changes at the edge of surface parking lots provide a subtle transition to surrounding areas. Avoid significant changes in grade (greater than 4 % slope) between the public sidewalk and pedestrian access and circulation routes. Ensure universally accessible routes are provided across any grade changes. b. Limit the maximum grades on landscaped areas to 33 % (3:1) or less to ensure that grassed slopes can be maintained. c. Limit the use of retaining walls, particularly along street frontages, parks, ravines, and other areas of the public realm. Where retaining walls cannot be avoided, minimise the overall height or provide low terraces, use durable, attractive materials, and incorporate intensive soft landscaping. d. Slope surfaces to direct stormwater toward landscaping, bio-retention areas or other water collection/treatment areas as identified on the site. 191 L.1.3 Lighting a. Select distinct luminaries with a coordinated appearance to light pedestrian pathways, parking spaces, drive aisles, building and site entrances, and other relevant parking lot features. Consider lighting elements for their aesthetic and design value, not simply their lighting function. b. Provide pedestrian-scaled lighting along pedestrian routes, such as bollards or lower-scale pole fixtures. Coordinate the location of lighting with pedestrian clearways, tree planting, and other landscaping. c. Install lighting that is appropriately scaled to its purpose, i.e. avoid “over lighting”. Direct light downward (no upward or horizontal light rays) and avoid light overspill on adjacent properties, streets, and open spaces. L.2 Vehicle Access and Circulation a. Limit the number and width of curb cuts for street access driveways to minimise interruption to the public sidewalk, streetscape, and perimeter landscaping. b. Provide access to surface parking lots from secondary streets or laneways whenever possible. Share driveway access between adjacent sites where feasible. c. Define street access driveways and internal vehicle routes with curbed landscaped areas, tree planting, and lighting. Ensure unobstructed motorist and pedestrian sightlines, and provide clearly marked crossings at all intersections between vehicle routes and pedestrian pathways. d. Size vehicle circulation routes according to use. Avoid over-sized driveways, drive aisles, and turning radii. Provide continuous circulation throughout the site. Avoid dead-end driveways and turn around spaces. L.3 Pedestrian Access and Circulation a. Establish a direct and continuous pedestrian network within and adjacent to parking lots to connect building entrances, parking spaces, public sidewalks, transit stops, and other pedestrian destinations. In larger parking lots or where parking lots serve more than one building or destination, provide designated pedestrian pathways for safe travel through the parking lot. b. Provide at least one pedestrian route between the main building entrance and a public sidewalk that is uninterrupted by surface parking and driveways. c. Provide pedestrian pathways along street access driveways. Where pedestrian routes cross street access driveways and other major drive aisles, clearly mark crossings and provide unobstructed sight distance for both pedestrians and vehicles. d. All pedestrian routes within a parking lot should include: i. A barrier-free pathway, with a minimum clear width of 1.7 m (wider pathways are encouraged and may be required depending on parking lot use); 192 ii. Shade trees (or a shade structure) along one or both sides of the pathway; iii. Pedestrian-scale lighting to illuminate and define the route; and iv. A clear division from vehicular areas, with a change in grade and surface material, and with soft landscaping. L.4 Landscaping L.4.1 General Requirements a. Consolidate soft landscaped areas, particularly in larger parking lots, to enhance tree and plant material growing conditions. b. Select plant material suitable to the growing environment of the parking lot. Avoid monocultures as they can be susceptible to disease. Incorporate a variety of deciduous and evergreen trees and shrubs for year-round interest, texture, shape, and seasonal colour. c. Trees should be planted at least 1.5 m from curbs, sidewalks, driveways, and other hard surfaces to buffer from stress caused by salt, snow piling, vehicle overhang, and compacted soils. All other plant material, except sod or groundcover, should be set back a minimum of 0.6 m from any curb edge to protect from vehicle overhang and mechanical damage. d. Where landscaping might impact motorist/pedestrian sight distance, prune trees and keep shrubs below 0.85 m in height so that the lowest branches will be at least 2 m above ground level. Limit any other landscape features that might cause obstructions to a maximum height of 1 m. Ensure overhanging branches of trees or shrubs adjacent to pedestrian pathways maintain a clear headspace of at least 2 m. L.4.2 Streetscape and Perimeter Landscaping a. Provide a landscaped area at least 3 m in width between surface parking and all property lines. b. For parking lot edges adjacent to streets, parks, or other public open spaces, provide at least one row of shade trees, spaced evenly at 5 m to 6 m intervals (or as appropriate to the selected species) for the length of the parking lot edge. Also provide screening, consisting of continuous planting, alone or in combination with a low decorative fence/wall or a landscaped berm. Keep shrubs, fences, or walls to a maximum height of 1 m. To support pedestrian safety and security, ensure screening does not completely obstruct views into and out of the parking lot. Set back screening at least 1 m from the edge of public sidewalks and 0.6 m from parking lot curbs. Screening shouldn’t encroach into the public street right-of-way. c. For parking lot edges not adjacent to the public realm, provide soft landscaping with a variety of deciduous, palm, and coniferous trees and plantings. d. Where possible, include landscaping and a pedestrian walkway between parking lots and building edges. 193 L.4.3 Internal Landscaping a. Incorporate soft landscaped areas and trees within the parking lot to define major vehicle and pedestrian routes, provide shade, and break up the expanse of paved areas. Soft landscaped areas include islands, medians, bio-retention areas, and other consolidated planting areas. b. Define internal landscaped areas with a continuous 15 cm curb to prevent damage from vehicles and snow clearance, to separate planting areas from pedestrian pathways, and to prevent soil and other landscape material from spreading over adjacent surfaces. c. Provide internal shade trees at a minimum ratio of one tree planted for every five parking spaces supplied. Distribute internal shade tree planting such that no parking space is more than 30 m from a tree. On small or narrow sites, shade trees provided in non-street facing perimeter planting areas can be counted toward the internal tree requirement, provided that the maximum distance from a parking space (30 m) is met. d. Include landscaped islands at the beginning and end of each parking row, and to break up longer rows or highlight special features. Plant at least 1 high-branching deciduous shade tree (2 preferred) in each island. Include understory planting such as shrubs, perennials, ornamental grasses, and groundcover. e. Provide continuous landscaped medians every 3 (or fewer) banks of parking. A “bank” of parking consists of 2 parking rows and a drive aisle. Medians should have a landscaped area at least 3 m in width and combine with shade tree planting requirements, pedestrian pathways, and/or stormwater management as appropriate. f. Shade structures may replace shade tree planting only after the minimum interior tree requirement is satisfied, or when sufficient soil volume and planting conditions cannot be achieved for proper tree growth. L.4.4 Stormwater Management Manage rainwater and snowmelt on-site with designs that encourage infiltration, evapotranspiration, and water re-use: a. Create bio-retention areas, such as swales, vegetated islands and overflow ponds. b. Include catchbasin restrictors and oil/grit separators as appropriate. c. Plant trees (if applicable) above grade from ponding areas and clear of stormwater flow. d. Provide cuts in curbs for water inlets / flow. L.5 Surfaces a. Install decorative paving or a change in paving material/colour to emphasise edges, pedestrian routes and crossings, entrances, loading areas, and other special features within the parking lot. 194 b. Limit the use of dark, impervious surfaces within the parking lot. Use light-coloured materials, such as concrete, white asphalt, green asphalt, or light-coloured pavers, in the hardscape to reduce surface temperatures and contribution to the urban heat island effect. c. Permeable and porous pavements provide an opportunity to retain rainwater and snowmelt onsite. Install permeable/porous pavement, such as open-jointed pavers, porous concrete/asphalt, or turf/gravel grids, as appropriate to parking lot use and conditions. Permeable paving should be installed in all overflow parking areas and is encouraged for use in snow storage areas and hardscapes surrounding trees. Consider turf grids/grassy pavers for areas of low traffic or infrequent use. L.6 Example Diagrams The next few pages provide some example diagrams of parking lots that meet all of these requirements.
