Due to ongoing drainage issues, the City of Vancouver hired McElhanney to help make improvements to the Southlands drainage network.
McElhanney provided an affordable and actionable plan that identified and addressed Sylvan Lake’s stormwater issues, and offered a phased road map and costing strategies to complete the work over the next 20 years.
McElhanney designed a 21,200m3 stormwater detention system for the Southwest Yorkson neighbouthood of Langley, BC. Due to land constraints, McElhanney proposed a non-traditional solution where the stormwater detention system was installed below sports fields in tanks.
In 2015 the City of Surrey needed a stormwater detention facility in Newton to accommodate future and existing development, improve water quality, and mitigate erosion within Hyland Creek.
