Tidal range is shown in various locations. These values were either taken directly from NOAA tide gauges or derived using NOAA's VDATUM software.

Metadata

Merged tax parcel boundaries from Accomack and Northampton Counties. These data are available to view (with other local data) on Northampton County's web mapping site and on Accomack County's web mapping site.

Detailed roads extracted from VGIN's statewide road centerline data. The localities and VDOT review and contribute to this dataset.

Metadata

This layer shows base zoning for Accomack County as of December, 2016. Metadata are not available. Contact the county for more information.

This layer shows base zoning for Northampton County as of December, 2016. Metadata are not available. Contact the county for more information.

Public schools in Northampton and Accomack Counties.

Metadata

These are point locations of fire and rescue stations in Accomack and Northampton Counties on the Virginia Eastern Shore. Note that most stations provide both fire and EMS services but some stations provide fire only and some provide EMS only. Data from both counties were merged and edited and verified based on high resolution aerial imagery.

Metadata

Schools in Northampton and Accomack Counties that serve as emergency shelter locations.

Highway 13 northbound is the only evacuation route on the Eastern Shore. This was extracted from road centerline data provided by VGIN.

See roads metadata for more information.

Data Fact Sheet

These are sites where the public can access the water on the Virginia Eastern Shore. They are primarily boat ramps but also include beaches, bulkheads, docks and other areas where public assess to the water is allowed.

Metadata

These are streams identified as impaired in the 2020 Virginia 305(b)/303(d) Water Quality Assessment Integrated Report.

These are 2014 flood hazard areas from FEMA, derived from Flood Insurance Rate Map (FIRM) databases and Letters of Map Revision (LOMRs).

Metadata

These are public lands or other lands protected from development through ownership or conservation easement. Included are Federal lands like National Wildlife Refuges and state lands like state parks, natural area preserves and state owned tidal lands. Ownership by various conservation organizations such as The Nature Conservancy and The Conservation Fund is also included. These areas were extracted from The Virginia Department of Conservatoin and Recreation's conservaton lands database.

Metadata

The Virginia Ecological Value Assessment (VEVA) delineates priority conservation areas ranked by level of importance based on VA Dept. of Game and Inland Fisheries' Priority Wildlife Diversity Conservation Areas, VA Dept of Conservation and Recreation Division of Natural Heritage Conservation Sites Layer (CSL) and Natural Lands Network (NLN), VCU Center for Environmental Studies aquatic resource integrity layer and VIMS College of William and Mary Center for Coastal Resource Management Cumulative Resource Assessment. It was originally published in 2011 by the Virginia Coastal Zone Management Program and was updated for the Eastern Shore in 2014 by The Nature Conservancy.

Metadata

This layer shows commercial aquaculture sites, areas allocated for bottom aquaculture of shellfish (primarily oysters and hard clams). These data points are managed by Virginia Marine Resource Commission (VMRC) in order to better assess, plan, and manage aquaculture development throughout Virginia's coastal zone.

Data Fact Sheet

In 1894 a massive two-year survey was conducted throughout State tidal waters (in the Chesapeake Bay and its tidal tributaries as well as on the Atlantic coast) to locate and map the naturally productive oyster beds, rocks, and shoals. Known as the "Baylor Survey," these areas are reserved for public shellfish harvesting and cannot be leased or used for other purposes.The Baylor Survey is still in use, and is shown on current oyster planting ground maps.

Data Fact Sheet

Location and extent of tidal marshes compiled from VIMS Center for Coastal Resources Management. Specifically, these data are from the Tidal Marsh Inventory. Data for Northampton County were updated in 2011 based on high resolution aerial imagery. Accomack County data are of an older vintage. Separate metadata documents are available for Accomack County and Northampton County.

This is extracted from the 2019 Chesapeake Bay SAV data. The annual SAV aerial photographic monitoring program provides a comprehensive and accurate measure of change in SAV relative abundance that has been used to link improving water quality to increases in bay living resources.

Metadata

This shows ground elevation at each point in a regularly spaced grid. These elevation values were derived from 2015 Eastern Shore LiDAR data and are based on the NAVD88 datum.

Soil Survey Geographic (SSURGO) database for Accomack and Northampton Counties. Separate metadata documents are available for Accomack County and Northampton County.

This data set represents the extent, approximate location and type of wetlands on the Eastern Shore from the U.S. Fish & Wildlife Service's National Wetlands Inventory (NWI). It does NOT necessarily represent jurisdictional wetlands.These data were derived from high-resolution aerial imagery with a range of dates between 2000 and 2011.

This is extracted from a nationally standardized, raster-based inventory of land cover for the coastal areas of the U.S. from the NOAA Office for Coastal Management.

Elevation surface based on LiDAR data flown for the Eastern Shore in 2015. LiDAR is a method for capturing very high resolution elevation data. This dataset shows ground elevation at 20 foot resolution. Elevation values are based on the NAVD88 datum.

Metadata

This layer represents population per square mile from the 2010 U.S. Census by census block. Blocks with a population of zero are not shown.

This layer represents the percent of population under age 5 by census block group for 2018. The source is the American Community Survey 2014-2018 5-year estimates. Block groups were clipped by The Nature Conservancy to show only the mainland and island areas on the Virginia Eastern Shore that are currently populated.

This layer represents the percent of population age 65 and over by census block group for 2018. The source is the American Community Survey 2014-2018 5-year estimates. Block groups were clipped by The Nature Conservancy to show only the mainland and island areas on the Virginia Eastern Shore that are currently populated.

This layer represents the percent of population employed in farming, fishing and forestry by census block group for 2018. The source is the American Community Survey 2014-2018 5-year estimates. Block groups were clipped by The Nature Conservancy to show only the mainland and island areas on the Virginia Eastern Shore that are currently populated.

This layer represents the percent of occupied housing units that are mobile homes by census block group for 2018. The source is theAmerican Community Survey 2014-2018 5-year estimates. Block groups were clipped by The Nature Conservancy to show only the mainland and island areas on the Virginia Eastern Shore that are currently populated.

This layer shows estimated total economic losses by Census block for the 1-percent annual chance flood. Economic loss data were developed using FEMA's HAZUS-MH risk analysis software. This software is based on current scientific and engineering knowledge, however there are uncertainties inherent in any loss estimation. Therefore, there may be significant differences between the modeled results and the actual economic losses following a specific flood event. Data shown here do not represent any single flood or event, rather they are derived from the maximum extent of modeled flooding at all locations across the entire Eastern Shore. As such, these data should only be used for planning purposes.
