Riparian Zone Restoration
Suitability Analysis Summary

Map and score areas near a stream, but not in a stream, where the natural condition of the riparian zone has been compromised. Examples include areas where the stream quality is impaired, agricultural uses extend right up to the stream, woody vegetation has been removed, etc.

Absolute Factors

  • Cannot be forested
  • Must be near (600’) but not in a stream or water body

Relative factors

  • In Biodiversity Conservation Network area (BioNet 4, 5 or new FIDS get ½ point)
  • In a Blue Infrastructure high priority watershed
  • In Chesapeake Bay Commission Critical Area (LDA or RCA only)
  • In a Biological Restoration Initiative Watershed
  • In a 100-year floodplain
  • In a stressed stream channel: channelization and/or has a lack of riparian buffer
  • Near (200’) but not in protected lands
  • In a Green Infrastructure “hub” (1 point) or “corridor” (1/2 point)
  • Near but not in a Wetland of Special State Concern
  • In Potential Migration Zones for wetlands, marshes, etc.
  • Near (200’) or in a GreenPrint Target Ecological Area
  • Is within 200’ (1 point), 400’ (2/3 point) or 600’ (1/3 point) of a stream
  • Is locally impaired: impaired for Nitrogren, Phosphorus, or sedimentation

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