About this dataset

This layer group contains vector versions of sea level rise planning scenarios for Hampton Roads, Virginia. The scenarios are based on the Hampton Roads Planning District Commission's (HRPDC) Sea Level Rise Planning Policy and Approach, as approved by the HRPDC on October 18, 2018: 
  • 2018-2050: 1.5 feet of sea level rise above current MHHW (mean higher high water) 
  • 2050-2080: 3 feet of sea level rise above current MHHW 
  • 2080-2100: 4.5 feet of sea level rise above current MHHW 
The policy and approach are available on the HRPDC website here. All scenarios were created by the HRPDC staff based on NOAA's "Mapping Coastal Inundation Primer," as described in the HRPDC report, "Hampton Roads Sea Level Rise Planning and Technical Assistance," which is available online here. 

Sea level rise scenarios were developed by HRPDC staff utilizing elevation and tidal surface data from USGS and NOAA.
