Compromised Stormwater Infrastructure Restoration
Suitability Analysis Summary

Map and score those areas where the natural hydrologic system is compromised. These areas present opportunities to incorporate best management practices. Some factors indicate that problems are likely to exist, some factors suggest an area is suitable for BMPs, and some factors indicate there is a maximum benifit to be gained. Note, however, that the selection of a specific BMP needs to be made at the site level.

Absolute factors

  • Cannot be in a floodplain
  • Cannot be a wetland
  • Cannot be forested
  • Cannot be in open water

Relative factors

  • in a Blue Infrastructure watershed
  • in a Biological Restoration Initiative (BRI) watershed
  • in an area that was probably developed before 1985 (1 point) or between 1985 and 2000 (½ point)
  • is area of relatively higher impervious surfaces
  • in an impaired watershed (as indicated by §303-d)
  • Is within 200’ (1 point) or within 600’ (½ point) of a stream designated for uses II, II or IV
  • In a Stronghold Watershed (1 point for “1”; ½ point for “2”)
  • in a Tier II watershed

Potential areas for Stormwater Management Restoration Opportunities, greatest potential being a 5.  Score being a representation of data layers present at that point versus number of possible layers.
