PAGE 4 <br /> control this pollutant load within the Protected Watershed-II <br /> district the first-one half-inch (1/2") of runoff from all <br /> impervious surfaces in new developments shall be controlled. <br /> The purpose of the stormwater control measure is to reduce off <br /> site effects by minimizing clearing, compaction and overall <br /> Bite disturbance, while maximizing vegetated areas for <br /> stormwater infiltration. Methods to accomplish this standard <br /> shall include, in order of preference: <br /> a. on-site infiltration through the retention of <br /> undisturbed, vegetated areas <br /> b. structural or engineered infiltration measures, such as <br /> trenches or retention ponds, which reduce the amount of <br /> runoff <br /> c. detention structures that reduce the rate of runoff. <br /> Areas to which the standard applies shall include individual <br /> lots or a new development as a whole. If applied to a <br /> development as a whole, the applicant umst provide for <br /> installation and maintenance of proposed stormwater <br /> management facilities. Applicants shall be required to <br /> submit documentation which indicates compliance with the <br /> specified standard. <br /> An individual lot of 80,000 square feet or more in size <br /> created by deed or plat in accordance with Orange County <br /> Subdivision Regulations prior to the adoption of this <br /> provision shall be exempt from this requirement upon <br /> submittal of a site plan which demonstrates that the <br /> development of the property is in accordance with the intent <br /> of this provision to minimize overall site disturbance; <br /> maximize maintenance of vegetated areas for stormwater <br /> infiltration; and protect critical drainageways and <br /> waterways from direct runoff impacts. <br /> mum= AMENDMINS): <br /> 6.24.6 Apiervious Surface Regulated .in ProtoctedWatersheas <br /> REVISE <br /> An liemprvious surface is a surface =posed of any <br /> material which impedes or prevents the natural <br /> infiltration of water into the soil. Such surfaces <br /> shall inc).ude, but not be limited to, streets and <br /> parking areas, sidewalks, patios and structures which <br /> cover the land. As a watershed becomes developed the <br /> amount of impervious surface increases causing a <br /> decrease in soil absorption of stormwater runoff and an <br /> increase in direct runoff to streams and other water <br /> bodies resulting in an increase in potential water <br /> pollution. <br />
