The Southwest Calgary Ring Road (SWCRR) will be built between Highway 8 (near Elbow Springs Gold Course) and Macleod Trail S.E.  The project includes the reconstruction of Glenmore Trail between Sarcee Trail and east of 37th Street S.W.  It consists of 31 kilometres of six- and eight-lane divided highway, 14 interchanges, 47 bridges, and one road flyover, one railway crossing (flyover), one culvert set, one tunnel, and three river crossings over the Elbow River and Fish Creek.

Allnorth provided preliminary engineering design services including stormwater modeling, minor system design and pond sizing (evaporation pond and wet pond), site grading, and road & parking lot design. A site layout was agreed upon and the detailed design was completed. Detailed engineering drawings and a stormwater report were completed to satisfy the requirements for a Development Permit and Environmental Protection and Enhancement Act (EPEA) applications for the City of Calgary and Alberta Environment and Parks, respectively.

The site was designed to have an evaporation pond with zero release to contain the areas subject to salt contamination, as well as a wet pond with a release flow rate at the pre-development conditions for all other areas of the site. The site will house a two-storey 10,000 ft2 office building, a 16,000 ft2 14-bay shop and a 17,600 ft2 salt and sand shed. 

The challenge on this site was balancing the earthworks due to 17 metre elevation change within the site. 

This elevation difference resulted in Canadian Road Builders Inc. obtaining ministerial consent to encroach within the Transportation/Utility Corridors (TUC) as well as to release a portion of non-salt contaminated water directly into the TUC without being controlled in the wet pond. An Erosion and Sediment Control (ESC) plan was also prepared and approved.  Allnorth is currently conducting construction inspection and contract administration with the project completion expected in 2020.
