PROJECT DESCRIPTION: The applicant is requesting Environmental (SEPA) Review and a Critical Areas
Exemption for the Madsen Creek Flood Improvement Project. The proposed project consists of four (4) sites requiring
improvements to restore and increase the lower Madsen Creek network flood protection and capacity, as well as provide
routine maintenance measures. Site 1 work consists of raising the berm surrounding the sediment basin and adding an
emergency spillway that discharges to the high flow bypass channel. Site 2 work consists of widening the high flow bypass
channel and removing accumulated sediments, as well as raising the right (east) bank of the upper high flow bypass
channel to eliminate the low spot acting as a weir diverting flows to the low flow channel. Site 3 work would raise the
elevation of the left (south) bank from the private property (14937 Maple Valley Hwy) through Wonderland Estates to
the low flow culvert under SR 169. The banks would be raised through a shallow floodwall and flood control berm. Site
4 work would remove the existing Eco Block wall along the right (north) bank of the low flow channel between the outlet
of the SR 169 culvert to the 149th Ave SE culvert entrance and replace it with a flood control berm. In addition to these
improvements, the high flow bypass capacity will be increased, and maintenance actions and agreements will be
implemented. The project site is mapped with a Type F stream, flood hazard area, seismic hazard area, wetlands,
wellhead protection area, zone 2, sensitive slopes, and protected slopes.
