Cp5CXVE5... TO <br />��``"m KZTTZTAiS COUNTY <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: Maggs Flood Claim <br />A portion of the site is considered part of the FEMA designated 100 -year floodplain. We have <br />no evidence of the levee breach upstream of the site flooded the property. It appears the river <br />over -topped the banks during the flood. Aerial photography from January 2009 near the site <br />indicates the stream flow remained within the designated 100 -year floodplain of the property. <br />No levee is located on the site. Some erosion may have occurred at the shoreline. <br />A newspaper article from November 26, 1959 reprinted in the North Kittitas County Tribune after <br />the January 2011 flooding event indicated the family residence on the property flooded. The <br />residents (Benetto family) reportedly moved in with another family. The property suffered bank <br />erosion where the river bends during a December 1980 flood event. A barn was severely <br />undermined as evidenced by an attached aerial photograph. The location of the barn is <br />vulnerable to erosion because the river bend at this location is severe. Stream velocity <br />increases at the outside portion of a bend. As velocity increases, so does erosion. The <br />aforementioned barn no longer exists. The property is flooded and eroded during each <br />significant event. <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, in the <br />curve of the left bank at the Benetto property, and at the left bank located near the end of Quail <br />Valley Road. It is unclear of who constructed these levees. The levee on the Benetto property <br />was referenced only once on a Corps of Engineers map circa 1951. The document was not <br />referenced at any other time. <br />Kittitas County does not retain ownership of the levees and never have. Kittitas County worked <br />with the US Army Corps of Engineers after the January 2009 flood event to reconstruct the one <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 />
