Below is a summary of the soil limitations that could be <br />encountered if this land is developed: <br />For Septic Systems: The Altvan loam 0% to 1 % slopes, and Aquolls and Aquents gravelly <br />susbstratum have severe limitations because of slow percolation. The Colby loans 3% to <br />5% slopes, Haverson loam 0% to 1% slopes, Kim loam 1% to 3% slopes, Kim loam 5% to <br />9% slopes, Weld loam 1% to 3% slopes and Wiley-Colby complex 1% to 3% slopes have <br />moderate limitations because of slow percolation. The Altvan loam 0% [0 3% slopes, <br />Bankard sandy loam 0% to 3% slopes, Cascajo gravelly sandy loam 5% to 20% slopes, <br />Dacono clay loam 0% to 1 % slopes have severe limitations because of poor filter <br />materials. The Aquolls and Aquents gravelly susbstratum have severe limitations because <br />of flooding and wetness. The Haverson loam 0% to I % slopes have moderate limitations <br />because of flooding. The Nelson fine sandy loam 3% to 9% slopes and Tassel fine sandy <br />loam 5% to 20% slopes have severe limitations because of shallow depth to bedrock. <br />For Small Commercial Buildings: The Aquolls and Aquents gravelly susbstratum have <br />severe limitations because of flooding and wetness. The Bankard sandy loam 0% to 3% <br />slopes and the Haverson loam 0% to 1 % slopes have severe limitations because of <br />flooding. The Cascajo gravelly sandy loam 5% to 20% slopes, and the Tassel fine sandy <br />loam 5% to 20% slopes have severe limitations because of potentially steep slopes. The <br />Colby loam 3% to 5% slopes, Kim loam 5% to 9% slopes, and the Nelson fine sandy loam <br />3% to 9% slopes have moderate limitations because of potentially steep slopes. The Weld <br />loam 1% to 3% slopes and Wiley-Colby complex 1 % to 3% slopes have moderate <br />limitations because of the shrink-swell potential of these soils. <br />PRIME FARMLANDS: This land is not considered prince farmland. <br />CONSERVATION-DEVELOPMENT~SELFGOVERNMENT <br />
