TRANSCRIPT
This project was a collaboration between the Cliff Bungalow - Mission Community Association and the Urban Lab, Faculty of Environmental Design. It was intended to provide an approach to neighourhood-based planning that would augment the City’s traditional, policy and zoning based Area Redevelopment Plan process and provide a new approach and a more comprehensive three-dimensional look at the neighbourhood’s urban structure. It was intended to provide tools for residents, planners, developers, architects and others involved in the community planning process to test development proposals and make better decisions regarding the community’s urban structure (the streets, blocks, and public spaces). Alternatives to current planning practice are offered, including alternatives to current zoning.

Cliff Bungalow - Mission is considered one of the most desirable urban areas of Calgary. It has a fairly high residential density and variety, a vibrant pedestrian culture, a lively commercial and retail core and is rich in history and culture. The neighbourhood’s location between the downtown and less dense residential districts makes it desirable for residential and commercial use, but also vulnerable to speculative development pressures. How any redevelopment takes place is an issue that needs to be considered.
APPROACH
This project assumed that the neighbourhood is the product of the inter-relationship of natural form and process with built form and community, over time. It is essential to understand the historical as well as the current forces responsible for the development of the built environment, together with the social processes and cultural expressions that give the community its life and soul. The project documented and analysed various aspects of the community form and process, and outlined recommendations for a better environment.
CONTEXT
Cliff Bungalow - Mission was analysed withing the context of the city and also within a more local context.
The neighbourhood is centrally located, and is geographically defined by the Elbow River and its escarpments.

LAND USES AND DENSITY
Land uses and densities were mapped using a variety of drawing types and graphic techniques.The neighbourhood was originally a primarily residential neighbourhood, with institutional land uses clustered around the Cathedral, hospital and schools, and commercial uses concentrated along 4th Street and 17th Avenue. The neighbourhood is now undergoing a transition to a mix of densities and uses.

Neighbourhood Existing Density MapF.A.R. is a generic measure of density calculated by dividing the total floor area by the lot area. With the exception of the high density towers along the Elbow River, most of the neighbourhood consists of low and medium density development.

HERITAGE RESOURCES
Heritage and character are formed by a combination of buildings, streetscapes and landscape. These elements, and their inter relationships, were mapped and graphically analysed.
This includes a partial inventory of landmark buildings, drawings of many character streetscapes, and analysis of building types. Each building type corresponds to a typical lot size and placement on the lot. These combinations of building type + lot size contribute to the overall character of the neighbourhood. The drawings analyze each building in terms of its structural components.
These drawings provide a record and a resource, and can be useful as a tool in defining the heritage value and character of the neighbourhood and in evaluating infill proposals.

TRANSITIONS
The transition between different building types, densities and land uses should be considered when evaluating proposed developments. The drawings right and below show an example of existing development illustrating good transition between building types, densities and land uses.
Example of development proposal to address orientation and surroundings, and provide better transition.
Public space is provided on the north east corner of the intersection in order to take advantage of solar exposure, and building heights are adjusted accordingly.

Alternative to existing RM-3 (RM-3*), with a maximum four stories and a height of 8 metres to the eaves, plus an extra 3 metres above within a 60 degree angle. The FAR (floor area ratio) is 2.3, 30% more than the existing RM-3 and RM-4, both at 1.8.
Example of the proposed new RM-5*, with a maximum five stories and a height of 11 metres to the eaves, plus an extra 3 metres above within a 60 degree angle. The FAR is 2.84, 20% more than the original RM-5.
ALTERNATIVE TO CURRENT ZONING
Several possible alternatives to current zoning were developed for discussion purposes. These alternatives are more responsive to the community character, with lower perceived height of buildings while allowing for comparable densities in a more flexible form.
