1f DPSC,DFS _ TU Tqe Cn <br />"" `°� KZTTZTAS COUNTY <br />D a <br />4p � <br />DEPARTMENT OF PUBLIC WORKS <br />Kirk Holmes, Director <br />KITTITAS COUNTY <br />TO: Neil Caulkins, DPA <br />FROM: Douglas D'Hondt, County Engineer, Public Works <br />DATE: February 17, 2011 <br />SUBJECT: Allen Flood Claim <br />The Allen's property is not considered part of the FEMA designated 100 -year floodplain. The <br />property was flooded as a result of a levee breach. It is not clear what the levee failure mode <br />was. The levee may have been overtopped causing erosion from the top down. The levee may <br />have been eroded from the toe within the river. Seepage may have allowed erosion from the <br />landward side resulting in a progressive failure leading to the river. Evidence of levee armoring <br />found downstream indicates the failure was likely due to erosion from the river side. <br />No record of a Kittitas County flood management system on the Teanaway River was found. <br />The only known levees are found immediately upstream of SR 970 on the right bank and at the <br />left bank located near the end of Quail Valley Road. <br />Kittitas County does not retain ownership of the levee and never has. Kittitas County worked <br />with the US Army Corps of Engineers after the January 2009 flood event to reconstruct the <br />levee for protection of Quail Valley and Lambert Roads. <br />USACE planned to finish the levee reconstruction summer 2011. KCPW will not complete the <br />construction until this claim is resolved. <br />411 North Ruby, Suite 1 TEL (509) 962-7523 <br />Ellensburg, WA 98926 FAX (509) 962-7663 <br />
