The following standards shall apply to any development proposed within the watershed protection overlay district:
A. There shall be no net increase in surface water runoff from any development, based upon the peak rate calculated for a ten-year storm. Runoff shall be directed to areas covered with vegetation for surface infiltration. Catch basins and piped storm sewers shall only be used where other methods are infeasible, and when such devices are used, they shall include a mechanism for separation of oil and grease.
B. Impervious material shall cover no more than fifteen (15) percent of any lot area, except for those uses which are allowed a maximum building lot coverage within a given district in excess of fifteen (15) percent, in which case the total area of impervious surface shall not exceed the maximum building lot coverage, as defined in article IX of this ordinance. In no case shall the maximum building lot coverage for a given use in any given district be exceeded.
C. No development, including any individual sewage disposal system (ISDS), shall take place, nor any natural vegetation be disturbed, within two hundred (200) feet of the Kickemuit Reservoir, any other water body or stream.
D. The construction of any ISDS shall be in compliance with state department of environmental management (DEM) standards, and the use of septic system cleaners and/or acids is prohibited.
