Background and Analysis:
The City's stormwater management program is regulated under the Western Washington Phase II Municipal Stormwater Permit (Permit), administered by the Washington State Department of Ecology (Ecology). The Permit is authorized by the 1972 federal Clean Water Act and the Washington Water Pollution Control Act (RCW 90.48) with authority delegated to Ecology. The permit requires local jurisdictions that operate a Municipal Separate Storm Sewer System (MS4) to develop and implement a broad array of stormwater management activities designed to protect downstream waters. Every five years the permit is reissued, often with new and updated requirements.

Staff will provide the UAC with a brief overview of new permit requirements and the Draft 2025 Stormwater Management Program Plan (SWMP Plan). A list of new Permit requirements and deadlines are included in the attachment to the staff report.
