New Hampshire’s Climate Risk in the Seacoast (C-RiSe) Project

New Hampshire’s Department of Environmental Services administers the Climate Risk in the Seacoast (C-RiSe) project which is intended to provide municipalities along the Great Bay with the resources they need to assess sea level rise and storm surge flooding. The Great Bay communities that have been assessed include: Rollinsford, Dover, Madbury, Durham, Newmarket, Newfields, Exeter, Stratham, Greenland, and Newington. This project is funded through the Coastal Zone Management Act by the National Oceanic and Atmospheric Administration (NOAA).  

C-Rise incorporates the following assessment components which help municipalities plan for climate change:

  • Sea-Level Rise and Storm Surge Inundation Mapping for each municipality.
  • Analyzing culverts and future climatic conditions to determine which culverts need to be replaced to permit the passage of aquatic organisms or increasing flows.
  • Assessing vulnerability to better understand the risk increased storm surge, sea level rise, and precipitation pose to municipal assets.
  • Incorporating vulnerability assessments and adaptation strategies into local hazard mitigation plans.

New Hampshire Granit (the state’s GIS clearinghouse), the state’s Coastal Program, the Rockingham Planning Commission, and the Strafford Regional Planning Commision partner with NOAA and the New Hampshire Department of Environmental Services to facilitate vulnerability assessments for municipalities, a few examples of which are included along with maps on the program’s website.  

The vulnerability assessment generated through C-Rise of all the municipalities in the Great Bay is available in a report with detailed results by asset type including:

  • Municipal Critical Facilities and Infrastructure
  • Transportation Assets
  • Culvert Assessment
  • Historic and Recreational Resources
  • Natural Resources
  • Freshwater and Tidal Wetlands
  • Critical Habitats
  • Locally Significant Natural Resources
  • Upland – Land and Water

The assessment report also describes the climate adaptation and coastal hazard activities in the Great Bay for each of the 10 municipalities assessed.
