The Edmonds storm drainage system is composed of streams, lakes, wetlands, detention systems, pipes and ditches - all of which discharge, largely untreated, to local water bodies, Lake Ballinger, and Puget Sound. City crews perform maintenance and repairs to the entire City-owned system to reduce flooding, improve water quality and protect the environment.
City - Maintenance and repair activities performed on the entire City-owned storm drainage system include inspection and cleaning of catch basins, street sweeping, emergency flood response, creek maintenance, inspection and monitoring of private stormwater detention systems, and minor capital improvement project construction.
Private Property Owners - Private property owners are responsible for properly maintaining the stormwater infrastructure on their property to ensure it operates as designed. The City has developed an inspection program to ensure private property owners are properly maintaining their stormwater systems.
