Lowe’s Home Improvement moved forward with their new Canadian National Distribution Centre on an 18.8 hectare site within the Escarpment Business Community located in Milton, Ontario in 2011. The facility provided Lowe’s with the initial 600,000 sq.ft of warehousing space they required to support their Canadian growth in a facility located within two kilometers from Highway 401 and within easy access to local and national shipping routes. The 60 million dollar facility was constructed in two phases with the first phase completed in 2014 and the second phase scheduled to be completed in 2016.
MGM Consulting was retained to provide site servicing, grading and stormwater management in support of the Site Plan Approval process and provide construction supervision during site works construction. Challenges associated with the site works design included achieving cost effective site grading given a single finished floor elevation stretching across a site with a 4 meter drop in grade at the building extremities and the development of a site abutting a sensitive tributary of 16 Mile Creek. The site grading design was completed achieving a cut-fill balance over the site, and as required to contain drainage and not impact the adjacent sensitive watercourse. On-site stormwater management features incorporated into the site design to meet local Town and Conservation Authority objectives included peak rate controls on the building roof and at ground level and stormwater quality controls including a linear bio-treatment feature to provide removal of a minimum of 80% of the total suspended solids from the site runoff.
