Stormwater runoff is the water from rain or melting snow that is not absorbed into the ground. Stormwater Management controls the quantity and quality of the runoff that is collected from homes and businesses, thereby reducing the risk of property flooding and protecting the health of streams.
Runoff is absorb into soil, where it is filtered and replenishes aquifers or it gets safely transported through a system of catch basins, pipes, pump stations, ditches/streams, and discharged to the Burrard Inlet, Coquitlam, Pitt and Fraser Rivers.
The importance of reducing stormwater runoff is essential as excessive runoff is causing erosion and degradation of water quality in stream and rivers. Below are several best practices that homeowners, builders and developers can implement to help protect our natural habitat.
For homeowners looking to determine and possibly reduce the amount of stormwater runoff from their property, the City has partnered with the Partnership for Water Sustainability in British Columbia to develop a Water Balance express tool. This tool enables homeowners to calculate the current amount of runoff from their property and experiment with actions to try and protect our creeks and watersheds.
