(4) Improper design and construction ofstormwater management practices can increase the velocity of stormwater runoff, thereby increasing stream bank erosion and sedimentation; (S) Impervious surfaces allow less water to percolate into the soil, thereby decreasing groundwater recharge and stream baseflow; (6) Substantial economic losses can result from these adverse impacts on the waters of the Village; (7) Stormwater runoff, soil erosion and nonpoint source pollution can be controlled and minimized through the regulation of stormwater runoff from land development activities; (8) The regulation of stormwater runoff discharges from land development activities in order to control and minimize increases in storm water runoff rates and volumes, soil erosion, stream channel erosion, and nonpoint source pollution associated with stormwater runoff is in the public interest and will minimize threats to public health and safety; and (9) Regulation of land development activities by means of performance standards governing storm water management and site design will produce development compatible with the natural functions of a particular site or an entire watershed and thereby mitigate the adverse effects of erosion and sedimentation from development. B. Purpose. The purpose of this article is to establish minimum storm water management requirements and controls to protect and safeguard the general health, safety, and welfare of the public residing within this j urisdiction and to address the findings of fact in § 285-77 A of this chapter. This article seeks to meet those purposes by achieving the following objectives: (I) Meet the requirements of minimum measures 4 and 5 of the New York State Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) General Permit for Stonnwater Discharges from Municipal Separate Stonnwater Sewer Systems (MS4s), PennitNo. GP-02-02 or as amended or revised; (2) Require land development activities to conform to the substantive requirements of the New York State Department of Environmental Conservation State Pollutant Discharge Elimination System (SPDES) General Permit for Constrnction Activities, Permit No. GP-02-01 or as amended or revised; (3) Minimize increases in stormwater runoff from land development activities in order to reduce flooding, siltation, increases in stream temperature, and stream bank erosion and maintain the integrity of stream channels; (4) Minimize increases in pollution caused by stormwater runoff from land development activities which would otherwise degrade local water quality; (5) Minimize the total annual volume ofstonnwater runoff which flows from any specific site during and following development to the maximum extent practicable; and (6) Reduce stormwater nmoffrates and volumes, soil erosion and nonpoint source pollution, wherever possible, through stormwater management practices and ensure that these management practices are properly maintained and eliminate threats to public safety. 5 40
