Reduce Impervious Areas

Why this matters to the lake?

When rain lands on impervious surfaces—roofs, roads, driveways, parking lots, sidewalks, etc.—it becomes runoff, picking up pollutants and sediments along the way, before reaching a water body, where it ultimately deposits them. Sediments reduce water clarity and smother bottom habitats; nutrients from lawn fertilizers and septic systems cause algae to proliferate; metals and chemicals from roofs, vehicles, and roads can have toxic effects on fish and other aquatic life and on water quality. Impervious surfaces that are warmer than the rainfall change the temperature of the runoff. Very warm runoff can create a thermal shock that harms or kills fish and microorganisms living in streams, wetlands, and along the lake’s edge.


  • Protect water quality by reducing stormwater runoff and pollutants from impervious surfaces
  • Preserve ecosystem services of watershed by maintaining natural landscape
  • Protect water habitat by buffering thermal impacts from runoff
  • Preserve undisturbed natural resources by locating development and redevelopment where existing infrastructure exists


  • Up to 3 points are awarded for retrofit and redevelopment projects—one point for every 0%-5%, 6%-10%, 11%-15%, reduction in existing impervious or Effective Impervious Areas within the project area.


  • For new development projects, one point is awarded for every 10% reduction below the maximum allowed in new impervious or Effective Impervious Areas within the project area (up to 3 points).
  • Three points are awarded for redevelopment or infill projects located in Hamlet or moderate intensity areas as defined by the Adirondack Park Agency Adirondack Park Land Use and Development Plan Map



Include the following information with application:

  • Indicate on the Proposed Site Plan measures implemented to reduce impervious areas, including:
    • Area of pervious pavement or green roof.
    • For retrofit and redevelopment projects, area of impervious surface removed and restored to meadow or forest conditions, including percentage of total impervious area removed.
    • For new development projects, measures taken to reduce impervious, such as smaller parking spaces, shorter driveways, and shared driveways, including estimate of impervious area reduction as a percentage of original impervious area estimated, as well as the maximum allowable impervious coverage permitted by zoning regulations.
    • Detail the Effective Impervious Area by the disconnection of impervious areas and include square footage areas . 
    • Indicate the property’s Land Use as defined by the Adirondack Park Agency Adirondack Park Land Use and Development Plan Map.
