Stormwater Account Information

In November 2017, the city council authorized the creation of a Stormwater Utility (Ord. 2624, 2017). This utility was established to properly fund the cost of all personnel, administration, equipment, maintenance, and stormwater projects necessary to insure the city stays in compliance with the National Pollutant Discharge Elimination System (NPDES) Phase II Municipal Permit issued by the Washington State Department of Ecology. Per EMC 14.10.510, the city determined that the stormwater system provides benefits and services to all property within the incorporated city limits. As such, there are no exemptions granted from the user fees. Monthly stormwater utility billing for all properties started September 1st, 2018.
