Climate Change - Corrotoman River - Mesohaline (CRRMH)

CURRENT COASTAL HABITAT COMPOSITION

  3.3 km² - Tidal Marsh
  3.4 km² - Submerged Aquatic Vegetation
  7.5 km² - Shallow Water
24.7 km  - Beaches

The Corrotoman River, a tributary of the Rappahannock River, is located in Lancaster County. Riparian lands are 34% developed (predominantly residential) with 23% of shorelines hardened. Lancaster County has a high average annual rates of permitted shoreline hardening of 3.5 km/yr (0.8% of the shoreline).


COASTAL HABITATS SHIFTS WITH CLIMATE CHANGE

  • Shallow-Water and Tidal Wetlands - depiction of existing tidal wetland (vegetated & non-vegetated) and shallow-water habitat, with projected shifts due to sea level rise

  • Tidal Marsh Vulnerability- depiction of existing tidal marsh and vulnerability to inundation from projected sea level rise within 50-100 years. Marshes classified at low risk represent potential wetland preservation opportunities

  • Estuarine Beach Vulnerability - depiction of existing estuarine beach and vulnerability to inundation from projected sea level rise within 50-100 years. Beaches classified at low risk represent potential habitat preservation opportunities

  • Submerged Aquatic Vegetation - depiction of existing submerged aquatic vegetation (SAV) and projected shifts due to sea level rise and elevated temperatures
