Stormwater Division

Mountlake Terrace was one of the first cities in the Puget Sound region to incorporate stormwater activities as part of a combined Utility Fund in the mid 1960s. On January 1, 2000 the Utility Fund was separated into Water, Sewer and Stormwater Utilities to provide a dedicated funding source to each division.


The mission of the Stormwater Utility is to maintain, operate and administer the City’s natural and developed storm and surface water conveyance system. The Utility ensures that the natural and developed stormwater systems protect water quality, enhance habitat, control flooding, and comply with state and federal requirements.


The stormwater management program developed through the Utility provides for a number of essential stormwater related activities including a comprehensive facility maintenance plan, a public education and outreach component, inspection of commercial and multifamily housing sites for proper operation and maintenance of stormwater treatment and control facilities, identification of illicit discharges to the stormwater system, spill cleanup response for accidental discharges, and management of a volunteer water quality monitoring program on Lake Ballinger.
