3 INTRODUCTION Welcome to Calgary Calgary is a young, prosperous, and rapidly growing city. However, in a changing world where global climate change is of growing concern, the danger of divergence between standard of living and quality of life is real. In response, the City undertook the Imagine Calgary process to develop a 100 year vision. The 18 month imaginecalgary public engagement process gave voice to over 18,000 residents, who developed a collective, 100 year vision for their city. Plan It Calgary Following imaginecalgary, on 8 January, 2007, City Council approved the Terms of Reference for the Plan It Calgary project (formerly the Integrated Land Use and Mobility Plan) The project goal is to provide inputs to an integrated Land Use and Mobility Plan as an update of the Calgary Plan (Municipal Development Plan) and the Calgary Transportation Plan. Council approved 11 Sustainability Principles (see page 6) to guide the project. Plan It Calgary seeks to integrate land use and transportation planning in a way that achieves these. To date, the City of Calgary - together with the Design Centre for Sustainability* - have been exploring the spatial application of these principles to the city. Southeast 17 Corridor Study The City of Calgary is currently undertaking a major planning study for the Southeast 17 Corridor (SE17), focusing on Land Use, Mobility and Urban design Issues. This planning study, begun in June 2007, will result in a Concept Plan for the Area (late Fall 2008), followed by a new, multi-community Area Redevelopment Plan (ARP) in late Fall As part of the Plan It Calgary process, the City is undertaking a case study charrette focusing on the 17 Avenue SE corridor. Charrette outputs will inform the generation of the Integrated Land Use and Mobility Plan. The Case Study will also provide an opportunity for Plan It Calgary outputs to inform other current planning activities, including the SE17 Corridor Study. The Study Area 17 Avenue SE is a main east-west commercial throughfare. The SE17 Corridor area includes properties within a five minute walk (approximately 600 metres in City of Calgary policy) on either side of 17 Avenue SE. The charrette study area includes portions of the following communities: Albert Park /Radisson Heights, Southview, Forest Lawn, Forest heights, Penbrooke Meadows, Applewood Park, and Forest Lawn Industrial. The area has a diverse mix of ethnicities represented along 17 Avenue SE, such that some know it by the name International Avenue. * The (DCS) is located in the School of Architecture and Landscape Architecture at the University of British Columbia. It is an academic leader in applying sustainability concepts to the development of land, cities, and community. 1

4 Plan It Calgary and Development Patterns CASE STUDY CHARRETTES The Plan It Calgary project has made extensive use of development patterns. Development patterns are assemblies of parcel and building types, land uses, local streets and open spaces. They are generic and replicable in many places across the city. These patterns contain information on employment and population, land use mix, parcel size, building types and dwelling units. This is a greater array and level of data than is contained in conventional land use planning tools. The use of development patterns also facilitates the modeling and measurement of scenarios and charrette outputs against sustainability indicators. The Plan It Calgary project created a palette of Calgary-specific patterns to produce large scale scenarios of the entire city. Several of these were then tested for accuracy and feasibility in a series of workshops, and then further refined. These new, refined patterns will be used in this case study charrette. The Plan It Calgary Case Study Charrettes The case study charrettes apply the development patterns to actual places in the city to gain a greater understanding of how they relate to each other. Detailed designs at the 1:2000 scale are also produced, to get a sense of what the eleven sustainability principles (page 6) might look like in a real place in Calgary. These designs may also inform the development of a Concept Plan for the SE17 Corridor Study, as work on this initiative continues through This charrette is one of multiple such case studies. The 17 Avenue SE Case Study Charrette will test ideas and scenarios developed through the Plan It Calgary process (land use and transportation) along the 17 Avenue SE corridor. In addition to the Plan It Calgary project, The City is also undertaking a major planning study along 17 Avenue SE, known as the SE17 Corridor Study. The SE17 Study was launched in June 2007 and will focus on Land Use, Mobility and Urban Design issues for the area. As part of the planning process for the SE17 Corridor Study, the City hired The Co-Design Group to facilitate a series of Visioning Workshops. Visioning Workshops were held in late January 2008 with the local community to develop a vision for the SE17 Corridor Study area. Participants generated drawings of how they would like to see their community look and feel in the future. From these workshop outputs, design strategies and measures were distilled, and are outlined in this document. These, combined with post policy documents and other design initiatives (all outlined in Appendix II and available for further reading), will inform the 17 Avenue SE Case Study charrette. The lessons learned from the Charrette will in turn inform the creation of the new Integrated Land Use and Mobility plan for Calgary, as well as other planning initiatives. Co-Design artists sketch participant visions.

5 Plan It Calgary PRINCIPLES In Jan. 2007, Council approved 11 Sustainability Principles for Land Use & Mobility to direct the Plan It Calgary project. These principles arise from Smart Growth principles, current City policy, and the imaginecalgary Long Range Urban Sustainability Plan. These principles provide the overarching direction for the 17 Avenue SE Case Study. Principle 1: Create a range of housing opportunities and choices. Provide a mix of housing types and ownerships in the same neighbourhood to allow residents to live affordably in the same community throughout their lives. A mix of housing creates a more adaptable and resilient community fabric as it is able to respond to demographic changes such as aging populations, empty nesters and smaller households. Principle 2: Create walkable environments. Create pedestrian-friendly environments with an interconnected street network to ensure walkable access to commercial and public services and amenities. Streets and arterials are designed for walking, cycling, transit access and cars. Neighbourhoods are sufficiently compact with mixed uses to provide sustained transit service. Principle 3: Foster distinctive, attractive communities with a strong sense of place. Create distinctive, high-quality communities designed with architectural and natural elements that reflect local conditions and the values of residents. Principle 4: Provide a variety of transportation options. Couple a multi-modal approach to transportation with supportive development patterns to create a variety of transportation options. This principle includes increasing the availability of high-quality transit service, creating resiliency and connectivity within the road networks, and ensuring connectivity between pedestrian, bike, transit and road facilities. Principle 5: Preserve open space, agricultural land, natural beauty and critical environmental areas. Maintain and restore ecosystem functions. Respect the natural functions of the landscape, particularly working agricultural land, watersheds and aquatic habitats. Design communities to integrate natural systems with human activities while placing high value on community access to natural systems and parks. Principle 6: Mix land uses. Mix land uses by having homes, businesses, schools and recreational opportunities in closer proximity. Mixed land use will provide alternatives to driving such as walking and biking while increasing transit viability. The resulting increased number of people on the street can enhance the vitality and perceived security of an area. Mixed land use is key to achieving more complete communities. Principle 7: Strategically direct and manage redevelopment opportunities within existing areas. Direct redevelopment towards and within existing areas to create and enhance places in existing communities. Stable areas will be preserved and the existing community context will be valued. Strategic intensification makes more efficient use of existing infrastructure and increases transit efficiency. Principle 8: Support compact development. development supports transit viability and modes of travel other than the automobile. It also allows for the preservation of open space and more efficient use of infrastructure. Principle 9: Connect people, goods and services locally, regionally and globally. Connectivity of all modes of transportation locally, regionally and globally ensures a more effective and efficient transportation system for people, goods and services. Principle 10: Provide transportation services in a safe, effective, affordable and efficient manner that ensures reasonable accessibility to all areas of the city for all citizens. Transportation services and infrastructure should be delivered in a cost-effective and energy-efficient manner. The transportation system should provide citizens with safe, barrier-free access to services that supply reasonable access to all areas of the city. Optimally designed and operated transportation systems help to improve the quality of life for citizens, support economic development and protect environmental health. Principle 11: Utilize green infrastructure and buildings. Utilizing ecological services provided by the environment will reduce community and environmental impacts as well as private, public and taxpayer costs of development and infrastructure. Green infrastructure can include energy solutions such as co-generation or renewable energy and water solutions such as stormwater retention and recharge. Green buildings include but aren t limited to externally certified standards such as LEED (Leading in Energy and Environmental Design), BOMA Go Green for commercial buildings and Built GreenTM for residential applications.

6 DESIGN INSTRUCTIONS: OVERVIEW The design brief provides the directions that will guide the charrette team over the course of the design event. The charrette team will use several inputs to produce a variety of outputs. Charrette Inputs The design team will work with the following inputs: Plan It Calgary Sustainability Principles Principles provide a set of guiding rules that are the basis for design; Principles provide a generalized framework to organize urban sustainability concepts; The Plan It Calgary process starts from the eleven Sustainability Principles adopted by Council; The eleven principles disaggregate into multiple objectives. Objectives Objectives are statements that define a desired condition; Objectives relate the general principles to a specific place; The Plan It Calgary objectives come from the imaginecalgary process and couple with the corresponding Sustainability Principles. Indicators Indicators offer a tool for measuring progress towards an objective; Each objective can have one or more indicators; Indicators provide a common basis for comparison; Indicators provide a mechanism for setting desired targets; This document presents the indicators for 17 Avenue SE as a series of scales, displaying performance values for the existing and compact scenarios. Development Patterns Neighbourhoods are made up of repeating patterns of parcel and building types, land uses, local streets and open spaces; These patterns can be studied and generic Development Patterns created; These patterns contain basic information on employment and population, land use mix, parcel sizes, building types, and dwelling units; Various patterns can be created for each land use category; These patterns can be used to model potential futures and assist planners and policymakers in their urban design decisions; In this charrette, the application of development patterns will enable indicator measurement of the charrette concept plan; More information on the development patterns is contained in the booklet at the back of this design brief. Co-Design Visioning Workshop Outputs Teams will have access to the drawings from the Co-Design visioning workshops held earlier this year. These provide further design strategies and should inform the team s outputs and discussions. 4

7 Required Charrette Outputs The design team is tasked with several outputs: Site plan Teams must together produce a concept plan of the study area, which when combined with theme - specific underlays from each team, will present a unified concept plan of the study area. Strategies Strategies are general implementation approaches toward achieving an objective; The Design Instructions include a range of possible strategies that are presented on the following pages; The proposed strategies do not represent a complete set. The charrette team must develop additional strategies to address the identified issue areas. Design measures Design measures represent a series of practices or actions that are solutions for achieving an objective; They demonstrate different ways of achieving objectives; Design measures offer very specific design-related instructions, and can refer to technologies, policies, programs, or programmatic requirements; The following pages list some potential design measures. Teams should consider these as a starting point from which to develop detailed design recommendations to inform a future Concept Plan. Performance Measurements Performance will be measured for each of the indicators identified after the charrette is complete. A desired output is to identify the target number validated through the design process. Illustrations and visualizations Sections, details, perspective sketches, and photoshop or 3-D visualizations all convey the discussions and support the concept plan. Phasing Teams must discuss and produce photoshop images of possible phasing options for the resultant concept plan. Development Pattern Allocation Allocation of the development patterns to the entire site (1/3 of site per team) must be completed to enable indicator measurement. The required outputs enable the measurement of the charrette concept against each indicator scale. In this way, upon completion of the charrette, a target can be identified that can make its way into future policy development in the area. 5
