Climate Change - Middle York River - Mesohaline (YRKMH)
CURRENT COASTAL HABITAT COMPOSITION
30.1 km² - Tidal Marsh
0.0 km² - Submerged Aquatic Vegetation
36.8 km² - Shallow Water
16.8 km - Beaches
The Middle York River is located in York, Gloucester, James City, King & Queen, and New Kent Counties. The segment extends from the polyhaline waters above Cheatham Annex to the mouths of the Pamunkey and Mattaponi Rivers (West Point). Much of the shoreline is undeveloped (12% developed riparian lands (mostly residential), and 5% hardened shoreline). As one moves upriver to less populated regions, average annual rates of permitted shoreline hardening decrease. York, Gloucester and James City Counties have moderate-high rates ranging from 0.5-1.3 km/yr (0.1-0.3% of the shoreline), and New Kent and King and Queen have low rates ranging from 0.1-0.2 km/yr (0.04-0.05% 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
