Stormwater Utility

Maintenance and Inspection Program

The goal of the City’s Inspection Program is to protect and restore our local water resources by ensuring a high performance level from current and future stormwater systems. This effort tcan reduce flooding and polluted runoff from reaching our streams, rivers, wetlands and Puget Sound.

Without regular maintenance and inspection, your system can become compromised, allowing water to directly discharged into local streams without sediment and pollution control. An unmaintained system could cause flooding on your property and those around you, resulting in costly damage or loss.

See the City's Inspection and Maintenance Brochure for more details.

Stormwater Utility Rate Study

The City Council adopted new utility rates based on needs identified in the 2016 Storm and Surface Water Management Comprehensive Plan, NPDES permit requirements, capital improvement projects and ongoing operations. The rate will increase annually by 19% between 2018-2020, and 2% in subsequent years. A new rate structure based on Equivalent Service Units will be implemented in 2019.
