This web-based tool helps planners visualize areas where current land protections are likely earning Community Rating System (CRS) points and other areas that may be eligible for future Open Space Preservation if protected by acquisition or conservation easements. The tool identifies areas within the floodplain that, if protected, improve the community’s CRS score, reduce flood insurance costs, and make their communities more resilient to flooding. It is also helpful for communicating the importance of conserving floodplains.



  • Visualize areas that currently qualify for Open Space Preservation (OSP) credit
  • Identify potential future OSP-eligible areas in the floodplain
  • Communicate flood risk and the importance of conserving floodplains to residents and decision-makers
