Description: The hydrants layers is point feature class representing fire hydrants in York County. The water lines and associated hydrants are not owned by York County. There are multiple water service providers within the County. New hydrant locations are provided to the County in digital format once or twice a year, when requested, and the layer is updated with that data. As individual new hydrants are placed by Newport News Waterworks, a memo citing the location is provided to the Fire Marshall and cc'd to the GIS Office, and the hydrant is added as accurately as possible, using the description. If other companies have installed new hydrants, York County does not receive notification of such.

Description: The PlatLink layer provides the means to research parcel configurations by capturing the area covered by each page of a subdivision plat that is legally recorded at the courthouse. Hyperlink fields are used to open the legal document.
Description: Control monuments represent York County's geodetic control monument locations. The foundation for the accuracy of the GIS is 130 survey monuments and 390 survey reference markers. These benchmarks are at strategic locations throughout the County to serve as mathematical framework for surveying, mapping, and aerial photographic projects.
Description: The zoning layer represents the boundaries of the various land used zones in York County. The zoning layer was created from the parcel data, and contains the most up-to-date board of Supervisors' approved designations.
Description: York County is divided into 5 election districts, with one supervisor elected from each district to serve on the York County Board of Supervisors. Each election district is further divided into two or more precicnts, for a total of 13 precincts in the County. Each precinct has its own polling location, established by York County Code Sec. 9-38.
Description: There are 10 elementary schools located in York County, Virginia. The location of a student's permanent residence determines the school he/she will attend. School District boundaries have not changed since the 2009-2010 school year.
Description: There are 4 high schools and 4 middle schools located in York County, Virginia. The location of a student's permanent residence determines the school he/she will attend. School District boundaries have not changed since the 2009-2010 school year.

Description: These files contain contours at 2' interval for the York Coutny, VA project area. The project encompasses approximately 51, 943 acres (~81 sq. miles) area of the York County, Va. The project area has been subdivided to North ( 27 sq. miles) and South (54 sq. miles). LiDAR data is acquired using ATLM 3100 sensor for these two regions and classified as First return and bare-earth data. The files are created in LAS format in Virginia State plane, South zone, NAD1983 coordinate system with US_Survey feet units. The LiDAR used for the generation of Digital Elevation Model (DEM) and Digital Surface Model (DSM). The bare earth LiDAR data was supplemented with 3D breaklines to provide a solid and very accurate base to use during the contour generation at 2 foot interval.
Description: These polygons represent areas of inundation from the Maximum of Maximum predicted storm based on the National Hurricane Center's Slosh Model, Orfmom. The vertical datum is NGVD29. A centroid point shapefile was created from the surge polygon shapefile. The point shapefile was then reprojected to Virginia State Plane, South Zone, Nad 83, U.S. Survey feet. A TIN was created from the point shapefile based on the maximum of maximum surge elevations(excluding elevations 99.9). The TIN was then converted to a GRID with a cell size of 10ft x10ft. A TIN was created from spot elevations and contours for the county. The TIN was then converted to a grid with a 10 x 10 cell size. Other cell sizes were attempted. However, the smaller the cell size below 10, the greater (exponentially) the file size. The larger file sizes were not feasible to work with. A map calculation was completed. The resultant grid, and subsequent shapefile represent areas of inundation and dry ground. Post-processing edits were made to better reflect surge elevations or to "smooth" polygons where the grid cells were too large for the area analyzed. Data is still in draft state and may need to be edited.
Description: The Digital Flood Insurance Rate Map (DFIRM) Database depicts flood risk information and supporting data used to develop the risk data. 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 DFIRM Database is derived from 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). The file is georeferenced to earth's surface using the UTM projection and coordinate system. The specifications for the horizontal control of DFIRM data files are consistent with those required for mapping at a scale of 1:24,000. Purpose: The FIRM is the basis for floodplain management, mitigation, and insurance activities for the National Flood Insurance Program (NFIP). Insurance applications include enforcement of the mandatory purchase requirement of the Flood Disaster Protection Act, which "... requires the purchase of flood insurance by property owners who are being assisted by Federal programs or by Federally supervised, regulated or insured agencies or institutions in the acquisition or improvement of land facilities located or to be located in identified areas having special flood hazards," Section 2 (b) (4) of the Flood Disaster Protection Act of 1973. In addition to the identification of Special Flood Hazard Areas (SFHAs), the risk zones shown on the FIRMs are the basis for the establishment of premium rates for flood coverage offered through the NFIP.

Description: In accordance with the objectives of the comprehensive plan, the Watershed Management and Protection Area Overlay regulations are intended to ensure the protection of watersheds surrounding current or potential public water supply reservoirs. The establishment of these regulations is intended to prevent the causes of degradation of the water supply reservoir as a result of the operation or the accidental malfunctioning of the use of land or its appurtenances within the drainage area of such water sources. A two hundred foot (200') [60m] wide buffer strip shall be maintained along the edge of any tributary stream or reservoir. The required setback distance shall be measured from the centerline of such tributary stream and from the mean high water level of such reservoir. Such buffer strip shall be maintained in its natural state or shall be planted with an erosion resistant vegetative cover. In the case of tributary streams located upstream from a stormwater manamgement facility designed to provide water quality protection, no buffer shall be required if such facility has been designed to accommodate and manage the quality of runoff from the subject site.

Description: Resource Protection Areas (RPA) of the Chesapeake Bay Protection Act of 1988 for York County, Virginia. The RPA is best described as land adjacent to water bodies with perennial flow, that have an intrinsic water quality value due to the ecological and biological processes they perform, or are sensitive to impacts which may result in significant degradation to the quality of state and local waters. The RPA layer is generally a 100' buffer of the water's edge on perennial streams that flow into the Chesapeake Bay. Building restrictions apply in these areas.
Description: Resource Management Areas (RMA) of the Chesapeake Bay Protection Act of 1988 for York County, Virginia. The RMA is best described as land that, if improperly used or developed, would have the potential for causing significant water quality degradation, or diminish the functional value, of a Resource Protection Area (RPA). The RMA layer is comprised of areas as within a 500' buffer of the outermost edge of the RPA. Some building restrictions apply in these areas.
