Detention of Excess Stormwater Runoff:
Each property owner shall provide for the on-site or off-site detention of excess stormwater runoff resulting from development. For the purpose of this Article, “excess stormwater runoff” includes all increases in stormwater resulting from an increase in the impervious surface of the site. This shall include all additions of buildings, roads, parking lots; changes in soil absorption caused by compaction, modifications in contours, including the filling or draining of small depressed areas, alteration of drainage ways, or re-grading of slopes; destruction of forest; alteration of drainage ways or installation of collection systems to intercept street flows or to replace swales or other drainage ways; or the alteration of subsurface flows, including any groundwater removal or diversion practices compared with the site in its natural state.
