Municipal Regulatory Stormwater Management & Erosion Control

  Comprehensive Plan Zoning Subdivision Site Plan
City of Ithaca   All new or enlarged parking areas, including combined drive ways and maneuver areas, need adequate runoff drainage for a 2-yr. storm, connection to public stormwater system Designed to accommodate runoff from undeveloped land uphill and where to discharge into natural or artificial surface drainage way; should not have greater rate than would under most severe conditions if were undeveloped Adequate; numbers on existing and expected increased loads on the system may be required
Town of Caroline     Drainage plan for 25 year flood.  No more storm water runoff than before development.  Protect and maintain exist systems (perennial and intermittent streams, swales and ditches etc). No construction, alteration or moving within drain course
  • Design goal: minimize opportunity for the soil to be moved by wind, precipitation, runoff and prevent sediment from reaching water body of other lands
 
Town of Catherine     When area subject to periodic overflow.  If top soil removal, other means to prevent runoff and erosion.  PB might require report if grading, excavating, filling involved  
Town of Cortlandville   Stormwater management and erosion and sediment control: No net increase in runoff between pre and post development for 2yrs, 10yrs, 50yrs-24hrs storm events; however, some perform standards more stringent: Water quality management: e.g. stormwater return to remove pollutants in Areas I and II
E.g. smallest area poss subject to erosion and sediment (maximum 2 acres), immediately stabilizing within 3days and seeding immediately after end of construction.  Board approval for excavation every year: considers soil erosion, drain, presence of farmland, slopes
