Such surfaces shall include any <br /> concrete or asphalt surface. These would include, but not be <br /> limited Ito streets and parking areas, sidewalks, patios and <br /> structures which cover the land. As a watershed beccnes <br /> developed the amount of impervious surface increases causing <br /> a decrease in soil absorption of stormwater runoff and an <br /> increase in direct runoff to streams and other water bodies <br /> resultidg in an increase in potential water pollution. <br /> In order to promote infiltration of stormwater runoff <br /> into the soil and to minimize direct and immediate runoff <br /> into streams and water supply impoundments, impervious <br /> surface patios shall be required as provided in the Table of <br /> ImperviOus Surface Ratios Section 6.23.4. Impervious surface <br /> calculations for an individual development shall be <br /> cunulative for original construction and any subsequent <br /> additions and calculations of impervious surface coverage for <br /> individual lots shall include that portion of a right-of-way <br /> between I the center line of the street and the abutting <br /> property line of the lot. <br /> ORDINANCE AMENDIMENT(S): <br /> 6.23.4 Maximum impervious Surface Ratios <br /> (PEE AMACHED TABtIE B) <br /> CRUM= AMMINDHENT(S):. <br /> 6.23.7 _o_ o _" o_ .1 I - -- k-Lt 4/7 41i r <br /> Stormwater runoff from impervious surfaces generally carry <br /> large amounts of oil, nutrients, netals, bacteria and other <br /> pollutants. The amount of such pollutants in stormwater <br /> runoff is closely associated with the land use from which it <br /> originates. An important determinant of water quality is the <br /> increase in impervious surfaces which prevent the natural <br /> infiltration of water into the soil. Most of the pollutant <br /> concentration is carried in the "first flush" of runoff. To <br />
