The VA_TOWN dataset is a feature class component of the Virginia Administrative Boundaries dataset from the Virginia Geographic Information Network (VGIN). VA_COUNTY represents the best available city and county boundary information to VGIN.VGIN initially sought to develop an improved locality and town boundary dataset in late 2013, spurred by response of the Virginia Administrative Boundaries Workgroup community. The feature class initially started from the locality boundaries from the Census TIGER dataset for Virginia. VGIN solicited input from localities in Virginia through the Road Centerlines data submission process as well as through public forums such as the Virginia Administrative Boundaries Workgroup and VGIN listservs. Data received were analyzed and incorporated into the VA_COUNTY feature class where locality data were a superior representation of the city or county boundary.
VA_COUNTY is a feature class representing locality (county and city) boundaries in the Commonwealth of Virginia. This dataset was derived from Census TIGER data supplemented with data made available from the cities and counties themselves.

Accurate against Federal Information Processing Series (FIPS), FIPS Publication 6-4, and FIPS-55 at the 100% level for the codes and base names. The remaining attribute information has been examined but has not been fully tested for accuracy.
The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles. Segments making up the outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. All polygons are tested for closure.
The Census Bureau uses its internally developed geographic update system to enhance and modify spatial and attribute data in the Census MAF/TIGER database. Standard geographic codes, such as FIPS codes for states, counties, municipalities, county subdivisions, places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when encoding spatial entities. The Census Bureau performed spatial data tests for logical consistency of the codes during the compilation of the original Census MAF/TIGER database files. Most of the codes for geographic entities except states, counties, urban areas, Core Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts were provided to the Census Bureau by the USGS, the agency responsible for maintaining FIPS 55. Feature attribute information has been examined but has not been fully tested for consistency.
For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-polygon SDTS Point and Vector Object Type reflects the number of records in the shapefile attribute table. For multi-polygon features, only one attribute record exists for each multi-polygon rather than one attribute record per individual G-polygon component of the multi-polygon feature. TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type classification. Therefore, when multi-polygons exist in a shapefile, the object count will be less than the actual number of G-polygons.
Data completeness of the TIGER/Line Shapefiles reflects the contents of the Census MAF/TIGER database at the time the TIGER/Line Shapefiles were created.

The layer includes buildings footprints for primary structures on lands at generally less than 10 feet ground elevation, which are areas that may be most vulnerable to coastal inundation. Critical facilities were identified using USGS National Structures Dataset.
Also included is a polygon depicting areas of Virginia that were not included in the analyses. These are lands generally higher than 10 feet in elevation and/or not contiguous with the Chesapeake Bay or Atlantic Ocean.

Study area/areas not included: Extracted areas with land elevation generally less than 3 meters (10 feet) from the Chesapeake Bay Topobathy DEM. To create a contiguous area, areas enclosed within (e.g., holes) a region of less than 10 feet were included in the study area. Similarly, areas that are less than 3 meters in elevation but not contiguous with the main study area adjacent to the waters were removed from the study area. A polygon of areas of Virginia outside of this study area was created for web viewer display.

Buildings: Extracted all building footprints from VGIN data and included only those that were greater than 870 square feet (determined to be a decent cut off for eliminating secondary buildings). Middlesex data was building presence only so included all footprints greater than 500 square feet. All boathouses were eliminated.

Buildings: Six localities did not have building polygons (Charles City, King and Queen, Lancaster, Essex, Hopewell, Colonial Heights). For these localities, impervious land cover was extracted and roads eliminated. Polygons greater than 870 square feet were kept as primary buildings.

Buildings: Community facilities were identified using USGS National Structures Dataset, and that coding added to building footprints.
