A hazardous waste spill, or other human contamination, can have a serious impact on an <br />aquifer, possibly rendering it unusable for years. <br />The primary water sources for the City of Cle Elum [as well as South Cle Elan and <br />Suncedia) are the Yakima and Cle Elum Rivers. lntakes are located below Lake Cle Elven <br />new the Bullfrog Road Bridge on the Cle Elum River, and on the Yakima River near the <br />intersection of South Cie Elum Way and the river. Shallow groundwater in Cie Elum area <br />renders the Yakima River intake susceptible to contmnination due to the relatively high <br />permeability of the Alluvium sail layer and a generally shallow depth to groundwater. <br />The Cie Elum River intake is susceptible to contamination resulting from the increased <br />development pressure for "lakefront" lots in the rural county. The predominant majority <br />of the homes permitted by Kittitas County are on individual septic systems in close <br />proximity to the ordinary high water mark of the lake. <br />The City has requested that Kittitas County establish land use intensity and proximity <br />Imitations to protect critical municipal water intake supplies. Best management practices <br />along with hazardous material plans, appropriate land use zoning and density, and the <br />analysis of future ft%mcts should be considered by the county to protect aquifers and <br />municipal water sources. The protection ofaquifcr recharge areas and municipal intakes <br />is modate d within the City if Cle; Elurn under Ordinance No. 1039, Section 18.01.120- <br />140, the 2004 Eastern Washington Stotmwater Management Manual, Best Management <br />Practices, and SEPA. <br />Wetlands and Floodplain <br />Wetlands are transitional areas between upland and aquatic esnvirownents where water is <br />pment long enough to form distinct soils where specialized plant commwrities can grow. <br />Wetlands include marshy areas along shorelines, and inland swamps. Wetlands are <br />typified by three physical characteristics; Hydric soils, hydrology, and hydrophilic plants. <br />The National Wetlands Inventory (NW'i) map prepared by the U.S. Fish and Wildlife <br />Service indicated that Cie Elum has a number of wetlands. Wetlands will be defined <br />using RCW 36.70A.030(20) and delineated using the Washington State Department of <br />Ecology Westland Delineation Manual pursuant to RCW 36.70A.175. <br />Cie Elum has several known areas designated by FEMA as Floodplain or Floodway. <br />Floodplains and floodways are areas recognized to have the; greatest risk of damage to <br />property and to the loss of human ilii. State law prohibits permanent strucum from <br />being constructed in the Floodway or to have zem rise (no displacement of floodwaters). <br />Only seasonal uses oz water dependent structures (such as bridges) should be allowed to <br />be constructed in these areas. <br />The protection of wetlands and floodplains occurs through the City's Development <br />Regulatlous for critical areas [Ordinance No. 1039, Section 18.01.290-300; and <br />18.01.430-500; respectively], and SEPA. <br />Historical and Cultural Preservation <br />City of Cle Elum — Land Use Plan 23 <br />
