STORMWATER MANAGEMENT PRACTICES (SMPs) - Measures, either structural or nonsh·uctural, that arc determined to be the most effective, practical means of preventing flood damage and preventing or reducing point source or non point source pollution inputs to stormwater runoff and water bodies. STORMWATER POLLUTION PREVENTION PLAN (SWPPP) - A plan for controlling stonnwater runoff and pollutants from a site during and after construction activities. STORMWATER RUNOFF - Flow on the surface of the ground, resulting from precipitation. SURFACE WATERS OF THE STATE OF NEW YORK- Lakes, bays, sounds, ponds, impounding reservoirs, springs, wells, rivers, streams, creeks, estuaries, marshes, inlets, canals, the Atlantic Ocean within the territorial seas of the State ofNew York and all other bodies of surface water, natural or artificial, inland or coastal, fresh or sa lt, public or private (except those private waters that do not combine or effect a junction with natural surface or underground waters), which are wholly or partially within or bordering the state or within its jurisdiction. Storm sewers and waste treatment systems, including treatment ponds or lagoons which also meet the criteria of this definition, are not waters of the state. This exclusion applies only to man-made bodies of water which neither were originally created in waters of the state (such as a disposal area in wetlands) nor resulted from impoundment of waters of the state. VILLAGE BOARD- The Board of Trustees of the Village of East Aurora. WATERCOURSE - A permanent or intermittent stream or other body of water, either natural or man-made, which gathers or carries surface water. WATERWAY - A channel that directs surface nmoffto a watercourse or to the public storm drain. Section 3. Chapter 285, Zoning, of the Code of the Village of East Aurora is hereby amended by adding a new Atiicle X\/, entitled Storrnwater Management, to read as follows: ARTICLE XV Stormwater Management § 285-77. Findings; purpose. A. Findings. It is hereby determined that: ( l) Land development activities and associated increases in site impervious cover often a lter the hydrologic response of local watersheds and increase stonnwater runoff rates and volumes, flooding, stream channel erosion, or sediment transport and deposition; (2) This stormwater runoff contributes to increased quantities of water-borne pollutants, including siltation of aquatic habitat for fish and other desirable species; (3) Clearing and grading duri11g construction tends to increase soil erosion and add to the loss of native vegetation necessary for terrestrial and aquatic habitat; 4 39
