May Creek Basin Plan
Final Adopted

May Creek Basin PlanThe Final Adopted May Creek Basin Action Plan was developed as a management tool providing regulatory guidance, programs, and capital projects aimed at these primary goals:

  • Reduce the threat of flooding to citizens in the May Creek Basin;
  • Make infrastructure improvements that will facilitate stormflow conveyance, stabilize stream banks, and reduce erosion;
  • Protect and enhance fish and wildlife habitat and water quality in the basin; and
  • Take reasonable steps to prevent existing problems from worsening in the future.

The King County Council adopted this basin plan on April 23, 2001. King County staff have now begun implementing primary recommendations in the plan.
