Primary surface water management objectives include:
  • The development of a fully functional storm and surface water infrastructure to serve the long-term needs of a growing community
  • The establishment of program elements to meet state and federal regulations
  • Maintaining and enhancing the habitat and environmental features associated with 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. See the final Watershed Planning Basin Assessment and Prioritization report. Currently a Stormwater Management Action Plan (SMAP) is being created to describe stormwater retrofit projects and programs that can be implemented in the prioritized areas.
