The Virginia Beach, VA EnviroAtlas Meter-scale Urban Land Cover (MULC) dataset comprises 3,724 km2 of southeast Virginia and includes Hampton, Newport News, Suffolk, Virginia Beach and Williamsburg. The area was selected based on the US Census Bureau's 2010 Urban Area for Virginia Beach, VA with a 1 km buffer added. These MULC data and maps are an adaptation of data developed in succession by three organizations. First, WorldView Solutions Inc., a contractor of the Virginia Geographic Information Network (VGIN), created an original dataset for the state of Virginia that used 6 inch to 1 foot-resolution, four-band (red, green, blue, and near-infrared), leaf-off imagery collected in 2013 for the Virginia Base Mapping Program, as well as 2015 VGIN LiDAR, and ancillary data inputs. These data did not fully capture tree canopy. Second, the Chesapeake Conservancy amended the original dataset using 2014, leaf-on United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) and 2010 and 2013 LiDAR data. The amendments added some of the tree canopy missing from the original data. Third, EPA amended the data further by collapsing multiple land cover classes into the seven EnviroAtlas Meter-scale Urban Land Cover (MULC) classes, and making corrections to the Wetlands classes, also using 2010 and 2013 LiDAR. Seven land cover classes were mapped: Water, Impervious Surfaces, Soil/Barren, Tree/Forest, Grass/Herbaceous Non-Woody Vegetation, Agriculture (Cultivated Crops) and Wetlands (Woody and Emergent). An analysis of 712 photo-interpreted land cover reference points yielded an overall user's accuracy of 83.5% (MAX) and an overall fuzzy user's accuracy of 84.1% (RIGHT) (see confusion matrices below). This dataset was produced by Virginia Geographic Information Network and their contractor WorldView Solutions Inc. (WSI), in collaboration with the Chesapeake Bay High-Resolution Land Cover Project - a cooperative agreement between the Chesapeake Conservancy and the National Park Service. It was adapted by the US EPA to support research and online mapping activities related to EnviroAtlas. EnviroAtlas (https://enviroatlas.epa.gov/EnviroAtlas) allows the user to interact with a web-based, easy-to-use, mapping application to view and analyze multiple ecosystem services for the contiguous United States. The dataset is available as downloadable data (https://edg.epa.gov/data/Public/ORD/EnviroAtlas) or as an EnviroAtlas map service. Additional descriptive information about each attribute in this dataset can be found in its associated EnviroAtlas Fact Sheet (https://enviroatlas.epa.gov/EnviroAtlas/DataFactSheets).

This map provides information on speed limits that are posted on state-maintained roadways in Virginia. Cities and towns set their own speed limits and these are not available to show on the map. Zoom in on the map to display the speed limits. Speed limits exist for all roads however; where this information is not available for mapping, they are not displayed. Most roads where speed limits are not shown are either rural, secondary roads (routes numbered 600 or greater) where a statutory 55 mph speed limit typically applies, or subdivision streets where a statutory 25 mph speed limit usually applies. These statutory speed limits are often are not posted on these roads. Click on any roadway to display the speed limit information.

This EnviroAtlas dataset shows the approximate walking distance from a park entrance at any given _location within the EnviroAtlas community boundary. The zones are estimated in 1/4 km intervals up to 1km then in 1km intervals up to 5km. Park entrances were included in this analysis if they were within 5km of the community boundary.

The Digital Geologic Map of the Colonial Beach South Quadrangle, Virginia and Maryland is composed of GIS data layers, two ancillary GIS tables, a Windows Help File with ancillary map text, figures and tables, GIS data layer and table FGDC metadata and ArcMap 9.1 layer (.LYR) files. The data were completed as a component of the Geologic Resources Evaluation (GRE) program, a National Park Service (NPS) Inventory and Monitoring (I&M) funded program that is administered by the NPS Geologic Resources Division (GRD). All GIS and ancillary tables were produced as per the NPS GRE Geology-GIS Geodatabase Data Model v. 1.3.1. (available at: http://science.nature.nps.gov/im/inventory/geology/GeologyGISDataModel.htm). The GIS data is available as a 9.1 personal geodatabase (coso_geology.mdb), as coverage and table export (.E00) files, and as a shapefile (.SHP) and DBASEIV (.DBF) table files. The GIS data projection is NAD83, UTM Zone 18N. That data is within the area of interest of George Washington Birthplace National Monument.

"This EnviroAtlas dataset describes the breakdown of the land cover classes with each Census Block Group. In this community, forest is defined as Trees & Forest, and Woody Wetlands. Green space is defined as Trees & Forest, Grass & Herbaceous, Agriculture, Woody Wetlands, and Emergent Wetlands. Agriculture is defined as Agriculture alone.Wetlands are defined as Woody Wetlands and Emergent Wetlands. This dataset also includes the area per capita for each block group for some land cover types.

This group includes the following items: 1. Hampton Roads Elevation Certificate Building Footprints: includes only building footprints where final elevation certificates are available, with elevations reported in the vertical datum provided on the elevation certificate (NGVD 29 or NAVD 88). 2. Hampton Roads Elevation Certificate Parcels: includes only parcels where final elevation certificates are available, with elevations reported in the vertical datum provided on the elevation certificate (NGVD 29 or NAVD 88). Where necessary, conversions from NGVD 1929 to NAVD 1988 were completed using the VERTCON (NOAA NGS, 2019). Elevation certificates were collected from the following 12 localities: Chesapeake, Franklin, Gloucester County, Hampton, James City County, Newport News, Norfolk, Portsmouth, Southampton County, Suffolk, Virginia Beach, and York County. Localities included in the current inventory were able to provide digital elevation certificate copies. This inventory is not complete for the region, and elevation certificates will continue to be added to the database when available. The elevation certificate database was developed by HRPDC staff with support from the Center for Geospatial, Science, Education, and Analytics at Old Dominion University (ODU). We would like to acknowledge Manuel Solano (ODU) for his contributions to the Gloucester County and City of Norfolk elevation certificate data development.Building footprints are courtesy the VGIN statewide building footprints layer and locality GIS departments. Building attributes and parcels are courtesy of the Hampton Roads Regional Parcels layer and locality GIS departments. Current flood zones are courtesy of the FEMA National Flood Hazard Layer, with base flood elevations reported in NAVD 1988 where available.

The Floodplain Mapping/Redelineation study deliverables depict and quantify the flood risks for the study area. The primary risk classifications used are the 1-percent-annual-chance flood event, the 0.2-percent-annual- chance flood event, and areas of minimal flood risk. The Floodplain Mapping/Redelineation flood risk boundaries are derived from the engineering information Flood Insurance Studies (FISs), previously published Flood Insurance Rate Maps (FIRMs), flood hazard analyses performed in support of the FISs and FIRMs, and new mapping data, where available. The FISs and FIRMs are published by the Federal Emergency Management Agency (FEMA).
