“The heart and soul of multicultural East Calgary”Downtown Calgary and Inglewood Community to the West

Regionally, Town of Chestermere to the East

Plan Area

“International Avenue”Multi-cultural Characters

Community PartnersPoor Infrastructure

Existing ConditionsArea stats3,000 residents and over 4,000 jobsbuild-out 30+ years: 13,000 more people and 9,000 more jobs

To Transition an established community with existing infrastructure into a transit-focused, liveable and distinctive mixed-use community:

Core of the Greater Forest Lawn Community Multi-modal boulevard Shopping avenue Showcase for the cultural diversity of the area Job hub and place to live Safe place Green and walkable

Vision

Policy AlignmentMDP (Municipal Development Plan)

Identifies the Plan Area as an Urban Corridor Typology with emphasis on a multi-modal boulevard fronted by a mix of higher intensity residential and business uses that foster a vibrant street environment.

Establishes a minimum intensity threshold of 200 jobs and population per gross developable hectare.

CTP (Calgary Transportation Plan)

Identifies 17 Avenue SE as an Urban Boulevard where highest priority should be given to walking, cycling and transit

Where the “Complete Street” policies should be implemented.

Land Developability

Parking Layout Efficiency

Parking Efficiency is expressed in square feet/metre of construction per parking space. Parking efficiency directly correlates with the construction cost per space. Build less structure per space and the cost per space drops.

PARKING EFFICIENCY MAKES A BIG DIFFERENCE – EXAMPLE• 360 sf / space X 500 spaces X $45 / sf = $8,100,000 • 330 sf / space X 500 spaces X $45 / sf = $7,425,000

A difference of $675,000 or $1,350 per space!

Typical ranges of parking structure efficiencies are: • Short Span Structural System = 330 to 390 Square

Feet (30 to 36 Square Metre) per Space • Long Span Structural System = 300 to 340 Square

Feet (28-31 Square Metre) per Space• Mixed Use Developments with retail, Residential

and Parking can be as high as 400 + Square Feet per Space
