This dataset contains model-based county-level estimates for the PLACES 2021 release in GIS-friendly format. PLACES is the expansion of the original 500 Cities Project and covers the entire United States—50 states and the District of Columbia (DC)—at county, place, census tract, and ZIP Code Tabulation Area (ZCTA) levels. It represents a first-of-its kind effort to release information uniformly on this large scale for local areas at 4 geographic levels. Estimates were provided by the Centers for Disease Control and Prevention (CDC), Division of Population Health, Epidemiology and Surveillance Branch. Project was funded by the Robert Wood Johnson Foundation (RWJF) in conjunction with the CDC Foundation. Data sources used to generate these model-based estimates include Behavioral Risk Factor Surveillance System (BRFSS) 2019 or 2018 data, Census Bureau 2019 or 2018 county population estimates, and American Community Survey (ACS) 2015–2019 or 2014–2018 estimates. The 2021 release uses 2019 BRFSS data for 22 measures and 2018 BRFSS data for 7 measures (all teeth lost, dental visits, mammograms, cervical cancer screening, colorectal cancer screening, core preventive services among older adults, and sleeping less than 7 hours a night). Seven measures are based on the 2018 BRFSS data because the relevant questions are only asked every other year in the BRFSS. These data can be joined with the census 2015 county boundary file in a GIS system to produce maps for 29 measures at the county level. An ArcGIS Online feature service is also available for users to make maps online or to add data to desktop GIS software. https://cdcarcgis.maps.arcgis.com/home/item.html?id=024cf3f6f59e49fe8c70e0e5410fe3cf

The Chesapeake Bay Preservation Ordinance was adopted to protect our local streams and one of the world's most productive estuaries, the Chesapeake Bay, from pollution due to land use and development. All of Fairfax County drains into the Potomac River and ultimately the Chesapeake Bay. In an effort to protect and improve the quality of these waterways, sensitive areas along streams throughout Fairfax County have been designated as Resource Protection Areas.State regulations require that Resource Protection Areas (RPAs) be designated around all water bodies with perennial flow. Perennial flow means that water always flows in the stream or other water body except during periods of drought. The Department of Public Works and Environmental Services conducted field studies to identify all perennial streams throughout the county and used this information to prepare a set of maps showing the location of RPAs as defined under the revised Ordinance. The maps were adopted by the Board on November 17, 2003. The data include the boundaries of the RPAs adopted by the Board in 1993 and the additional RPAs adopted by the Board in 2003. These are general locations of RPA boundaries for planning purposes and the actual limits may be further refined by detailed field studies conducted at the time a plan is submitted to obtain a permit to develop a property.Any areas within Fairfax County not contained within the RPAs are Resource Management Areas (RMAs). Together, the RPAs and RMAs comprise the Chesapeake Bay Preservation Areas.

In September 2020, the Loudoun County Board of Supervisors directed staff to document telecommunication projects completed, in-progress, and future projects, using the 2014 Wireless GAP Analysis and the Segra Dark Fiber Area Network. Staff mapped the data identified by the Board, as well as other information related to telecommunication projects. This information was then used to identify select unserved or underserved geographic areas of the county.The companion interactive map allows the user to turn on or off all layers used in the project.

This layer represents the Virginia Senate districts that are within Loudoun County. Virginia Senate districts represent the area that each elected member of the Virginia Senate represents. The Senate districts are revised and adopted by the Commonwealth of Virginia each decade. The Commonwealth of Virginia redraws its House districts based of the results of the most recent decennial census, in this case the 2020 Census. The Virginia Supreme Court unanimously approved congressional maps for the state and district maps for the Virginia House of Delegates and Virginia State Senate on December 28, 2021.

This data set contains a variety of easements that are captured from recorded subdivision plats and easement plats. Once a document has been recorded then the GIS Division receives that document and creates any features that are shown on the recorded document. This layer contains the easement type by category and the name of the easement as stated on the plat. For newer easements there is also the deed book and deed page. This is used to perform research on the original document in the Courts system.

This layer does not contain all easements. There are many easements before the GIS Division started capturing all easements that did not get into the layer because they were not on the original mylars where this data was captured from. Also, in 2016 the GIS Division stopped capturing stormwater easements into this layer as there is different layer that contains the stormwater related easements.

This GIS layer contains the geographical boundaries of the incorporated towns as of the 2020 Census.

"The digital topographic map is a United States Geological Survey (USGS) product. The original topographic maps for each county have been scanned and rectified (assigned coordinate information). The collars (the white margins along the sides of the map) have been removed. In addition, all topographic maps for a given county have been tiled together to provide seamless topographic coverage for each locality. The source scale of this product is 1: 4,000. It is available as a Mr. Sid (proprietary format that is “readable” by ArcGIS).For more information on this data refer to the supplemental metadata pdf found at: https://secure-archive.gis.vt.edu/gisdata/public/UnitedStates/Virginia/VCE_2002_metadata/METADATA.pdfThis data has been curated by the Virginia Cooperative Extension at Virginia Tech and Virginia Tech University Libraries.
