A cornerstone of Team Three’s concept is the application
of Best Management Practices (BMPs) for on-site treatment
and control of stormwater runoff. As the following two sections
reveal, the physical dimensions of the Willingdon Parkway
would vary according to the level of remediation needed.
The
top drawing shows an average section of the parkway. Shown here
at its maximum width of 20.6 metres, the boulevard occupies
almost half of the entire right-of-way and becomes, in essence,
a linear park. At this width it is well able to accommodate
a large and diverse palette of native trees and ground cover.
Wetland plantings cleanse urban runoff and assist in providing
habitat for waterfowl, fish, and other wildlife. The remainder
of the right-of-way consists, on either side, of 7.6 metres
of paved roadway, a 4.0 metre allowance for street trees, and
a 2.5 metre sidewalk.
Section
of the Willingdon Parkway as it approaches the town centre,
where the parkway intersects with Lougheed Highway. A greater
intensity of use is expected near the community hub. In response,
the central boulevard is narrowed to 14.6 metres and three lanes
of traffic are accommodated on either side within 11.2 metres
of paved roadway respectively. Traffic is buffered on either
side by street trees and 2.5 metre sidewalks.
