Climate Change - Elizabeth River - Polyhaline (ELIPH)
CURRENT COASTAL HABITAT COMPOSITION
0.3 km² - Tidal Marsh
0.0 km² - Submerged Aquatic Vegetation
3.2 km² - Shallow Water
0.3 km - Beaches
Mainstem Elizabeth River, located in the Cities Norfolk and Portsmouth, is a highly developed harbor with military and industrial use, including the US Army Disposal Area at Craney Island. The segment has approximately 61% developed riparian lands and 18 km of hardened structure (69% of shoreline altered). Portsmouth and Norfolk have moderate-high average annual rates of permitted shoreline hardening ranging from 0.2-1.1 km/yr (0.2-0.4% 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
-
Vulnerable Developed Lands - depiction of existing developed lands and vulnerability to inundation from projected sea level rise
