Private Storm Drainage System Management

Private Storm Drainage System Maintenance

Maintaining Your Stormwater System

The City of Auburn requires property owners to inspect and maintain stormwater systems on their private property. The City inspects private stormwater systems to ensure that they are functioning properly. It is important that property owners maintain these systems to prevent pollutants from entering the drainage system and surface waters of Auburn.

Stormwater systems are designed to collect and control runoff, prevent flooding, and keep pollutants out of surface waters. This benefits everyone by providing safe use of City streets and clean recreational waters to enjoy. Regular maintenance on storm system catch basins, ponds, and ditches is not time consuming or difficult. Contact information for the Storm Utility and the City's minimum maintenance standards are below.

City of Auburn Maintenance Guidelines

All private storm systems are required to meet the Maintenance Standards for Drainage Facilities found in Volume V of the Washington State Department of Ecology (Ecology) Stormwater Management Manual for Western Washington (SWMMWW), found here:
