• EXISTING ORDINANCE PROVISION(S) : Impervious Surface Requalted in Protected Watersheds. An impervious surface is any surface thorugh which water cannot penetrate or can only penetrate slowly. This would include paved streets and parking Lots, concrete sidewalks, and structures which' cover land. As a watershed becomes developed, the amount of impervious surface increases causing a decrease in soil absorption of stormwater and an increase in direct runoff to streams and water supply impoundments. In order to promote infiltration of stormwater runoff into the soil and minimize direct and immediate runoff into streams and water supply impoundments impervious surface ratios shall be required as provided in Section 6.23.4. PROPOSED ORDINANCEIAMENDMENT(S) : S.24.9 Impervious Surface Regulated in Protected Watersheds REVISE An impervious surface is a surface composed of any material which impedes or prevents the naturel infiltration of water into the soil. Such surfaces shalli include, but not be limited to , streets and parking areas , sidewalks, patios and structures which cover the land. As a watershed becomes developed the amount of impervious surface increases causing a decrease in soil absorption of stormwater runoff and an increase in direct runoff to streams and other water bodies resulting in an increase in potential water pollution . In order to promote infiltration of stormwater runoff into the soil and to minimize direct and immediate runoff into streams and water supply impoundments, imper0ous surface ratios shall be required as provided in the Table of Impervious Surface Ratios Section S .23.4. Impervious surface calculations for an individual development shall be cumulative for original construction and any subsequent additions and calculations of impervious surface coverage for individual lots shall include that portion of a right- of—waif between the centerline of the street and the edge the abutting property Line of the lot.
