The City of Redmond inspects all stormwater facilities and structures, including vaults, ponds, and catch basins, to ensure they continue to function/comply with design and construction standards. These stormwater systems slow down or collect stormwater runoff after rainfall and snow melt and allow suspended sediments and solids to settle out or be removed before the water enters our streams, wetlands, and lakes. They are installed to help prevent flooding and erosion and protect Redmond’s waterways from pollution.
The City of Redmond has been inspecting stormwater facilities and structures at industrial, commercial, and manufacturing properties, as well as multi-family, apartments and condos, since 1996. Private Drainage Inspection Program staff work with businesses and property managers in a cooperative effort to reduce pollution and bring private stormwater systems into full operation. In Redmond, owners of private stormwater facilities typically receive a discounted stormwater utility fee, so it is to the property owner's advantage to maintain them.
In 2010, the City of Redmond began inspecting stormwater facilities and structures on private plats and short plats, as required by the Department of Ecology NPDES Phase II requirements. Currently, the City visits each site every two years.
