Riparian Zone Preservation
Suitability Analysis Summary

Map and score areas near a stream, but not in the stream, that are contributing positively to stream health. Examples include areas that are heavily wooded, or have other woody vegetation near the stream, which prevent erosion.

Absolute factors

  • cannot be protected
  • must be near (600’) but not in a stream or water body

Relative factors

  • In a Biodiversity Conservation Network area (BionNet 1, 2, or 3)
  • In Biodiversity Conservation Network area (BioNet 4, 5 or new FIDS get ½ point)
  • In a Blue Infrastructure high priority watershed
  • in a 100-year (1 point) or 500-year ( ½ point) flood plain
  • In Chesapeake Bay Commission Critical Area (LDA or RCA only)
  • In a Biological Restoration Initiative Watershed
  • In a 100-year floodplain
  • is forested
  • In a Green Infrastructure “hub” (1 point) or “corridor” (1/2 point)
  • in a Wetland of Special State Concern
  • Near (200’) but not in protected lands
  • In Potential Migration Zones for wetlands, marshes, etc.
  • Near (200’) or in a GreenPrint Target Ecological Area
  • In a Healthy Watershed (Stronghold, spawning, cold water, or Class III trout)
  • is within 200’ (1 point), 400’ (2/3 point) or 600’ (1/3 point) of a stream

    Potential areas for Riparian Zone Preservation Opportunities, greatest potential being a 5.  Score being a representation of data layers present at that point versus number of possible layers.
