activity increases. The increased impervious area, such as <br /> roads, parking lots, and roofs, alters the relativelume of <br /> magnitudes of runoff and infiltration. A greater <br /> runs off the land at an increased velocity. It is <br /> carried quickly via natural drainage ways or storm drainage <br /> systems. The process of infiltration and soil purification <br /> does not have an opportunity to function. <br /> As a result, the <br /> water quality ofsnQe lchofthrough <br /> pollutionacansbean be <br /> very poor even i f point sources <br /> identified. <br /> Any plan to protect water supply watersheds needs to identify <br /> and reduce the water quality alit impacts of both non-point and <br /> point sources of pollution. An important component of any <br /> water quality plan for the County should direct sewage <br /> toxic waste disposal sites, landfills, and <br /> treatment plants, <br /> industrial operations which manufacture or produce as a <br /> by-product potentially hazardous materials away <br /> watershed areas. <br /> A equally important, if less obvious, part of a watershed <br /> protection plan should be to keep the density of development <br /> in watershed areas as low as possible, directing <br /> expansion of urban areas away from water supply watersheds. <br /> water Resources Planning in Orange County <br /> In 1979, the Orange County Board of Commissioners appointed <br /> the Water Resources Task Force, investing in it five charges: <br /> 1) defining water quality goals for Orange County; <br /> 2) reviewing water resources data and compiling an inventory <br /> of existing and potential reservoir site ; protection <br /> 3) developing, reviewing, and ranking w <br /> strategies; <br /> 4) preparing the water resources section of the County Land <br /> Use Plan; and, plan <br /> 5) recommending a long term water resources management <br /> for Orange County. <br /> From these charges, a final report was issued in May 1981 <br /> detailing seventeen separate recommendations. The <br /> recommendations could be loosely grouped into five areas; <br /> land use regulation, conservation, erosion control, <br /> infrastructure, and water supply. <br /> The land use regulation recommendations centered around <br /> identifying watersheds to be protected and adopting <br /> 2.3 text 10 <br />
