The City of Delta is planning a major infrastructure project to better protect a low lying rural area of East Ladner from flooding.
Council this month awarded a $221,200 contract for an engineering firm to come up with the design for the new 84 Street Pump Station.
The pump station project will include a new 1.8-kilometre long force main to send flows to Boundary Bay, a foreshore discharge structure that crosses the Boundary Bay Dike and related foreshore enhancement works near the outfall area in the bay.
The project is to address flooding of low lying areas south of Ladner Trunk Road, as well as provide additional pumping capacity required to service an industrial development.
The construction is anticipated to be completed in multiple phases, subject to funding availability.
A previous staff report notes the Center and Beharrel Drainage Area is approximately 1,200 hectares, stretching from north of Highway 99, south to Boundary Bay and between 72 and 96 Streets.
The ground elevation is low.
“Without a robust drainage and dike system, this area is susceptible to regular flooding. There is a need for the system to be upgraded as runoff during winter months results in flooding in the low lying areas. A drainage pump station, force main, and ditch improvements are required to service this low lying catchment area…In addition, upgrades to the existing Beharrel system are required to improve storm water drainage,” the report explains.
The city is hoping to secure senior government funding to help pay for the project, which has a preliminary cost estimate of $6.5 million.
