This page provides State Environmental Policy Act (SEPA) documents for the May Creek Drainage Improvement Project 9A1205, including the Mitigated Determination of Non-Significance and Environmental Checklist.

For the project May Creek Drainage Improvement Project 9A1205, King County proposes to improve in-stream flow conditions along segments of May Creek in May Valley and reduce the duration of flooding along May Creek between approximately River Mile 4.3 and 4.9 by removing stream channel obstructions and restoring a buffer of native riparian vegetation.
