Surface Water Management

Duties & responsibilities

Marysville Surface Water Management is committed to a pro-active approach in managing storm and surface water impacts within the City of Marysville and maintaining and enhancing the aquatic resources within the Quilceda / Allen watershed.


Primary surface water management objectives include:

  • The development of a fully functional storm and surface water system to serve the long-term needs of our growing community
  • The establishment of program elements to meet state and federal regulations
  • Enhancement of the habitat and environmental benefits derived from the Quilceda/Allen watershed

Comprehensive Planning

The City of Marysville's Surface Water Comprehensive Plan presents an analysis of Marysville’s surface water system and identifies Capital Improvement Program (CIP) projects to correct deficiencies. It also provides a general overview of each of the City’s four watersheds: Quilceda Creek, Allen Creek, Sunnyside Creek, and Ebey Slough.

The City has completed a watershed assessment and prioritized streams that would receive the most benefit from additional actions.

The Stormwater Management Action Plan (SMAP) describes stormwater retrofit projects and programs to be implemented in the prioritized areas. These two documents will be used in conjunction with the Capital Improvement Program to plan stormwater projects in the future.
