This feature keeps track of all known building structures in Roanoke County. It is currently being maintained by GIS Services for all new structures. It was created from aerial digital images.

Planning Area Boundaries are design to facilitate long range planning at the community level. Roanoke County’s community planning areas were established in the mid-1980s as part of the 1985 Comprehensive Plan. Planning area boundaries were based upon a combination of tax map limits, elementary school districts, and community characteristics. Most of the names for the planning areas are loosely based on community elementary schools and fire and rescue stations. The planning area boundaries were updated in 2011 to correspond with recent planning area studies. Planning Area Boundaries are maintained within the Administration Feature and is dissolved out weekly.Administration is a polygon feature consisting of the smallest statistical areas bounded by visible features such as roads, streams, railroad tracks, and mountain ridges, as well as by nonvisible boundaries such as jurisdictional limits, school district, public safety boundaries, voting precincts, and census blocks. This methodology allows for single stream editing to move coincidental boundaries across many aggregate datasets simultaneously. Administration is maintained though an ArcGIS topology class in conjunction with County Parcels and Zoning. The topology prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.

This Administration feature is the single most valuable feature maintained by the GIS Services staff. It combines the maintenance of many individual polygon features in one main overall feature.It is part of a ArcGIS Topology class maintained with our parcel and zoning features in the Editing Feature Data Set.We use the shared editing capabilities of this topology class to leverage our maintenance procedures as simply as possible. Weekly, the individual features maintained with our Administration feature are created with ArcGIS dissolve function. These include Jurisdiction boundaries, Public Safety Response areas, Voting Precincts, Schools Attendance Zones, Inspections, Library Service Zones, and more.Generally, maintenance of this feature is controlled thru shared editing performed with our parcel/zoning edits with the use of the Topology features in ArcGIS. Changes to features maintained in the Administration feature are caused by a number of issues. Parcel edits, new Public Safety Stations, changes in Voting Precincts, Police Reporting districts and other changes occur often. Most changes can be facilitated by selecting one or more “Administrative” polygons and changing the appropriate attribute value. Use of the “Cut Polygon” task may be necessary in those cases where part of a polygon must be changed from a district to another. The appropriate attribute can be changed in the affected area as necessary.

Areas included: Bedford County, Botetourt County, Craig County, Floyd County, Franklin County, Montgomery County, Roanoke City, Roanoke County, and Salem City

Railroad polyline feature was digitized by GIS Services staff from our 2011 aerial photography and includes Roanoke County and all adjacent jurisdiction areas. This includes track owned by Norfolk Southern and CSX.

Medical Centers (Hospitals) contain a point location for public locations within Roanoke County and the surrounding localities. These points fall into the following categories: Schools, Parks & Rec, Polling Places, Public Safety, Libraries, Administration, General Services, Post Offices, Hospitals, and Museums. Each location is attributed with hours of operation, contact info, and URL reference. Subset categories are extracted to create standalone features such as School Sites in the Schools Dataset.

Contours 2 Foot of South West Quadrant of Roanoke County.

Signed Intersections is a point feature listing the names of all road segments that intersect at a given point. Thiese points are updated weekly through an automated process.

Contour 100 Foot.

Clearbrook village overlay district promotes future development that is consistent with the current character of Clearbrook, and with the comprehensive plan future land use map and policies for this area. Future development in this district should respect the character and historical context of the Blue Ridge Parkway, Clearbrook School, and other social and cultural resources in Clearbrook area. See Roanoke County Code: SEC. 30-58. - CVOD CLEARBROOK VILLAGE OVERLAY DISTRICT

Stormwater management, as a specialized area within the field of environmental engineering, emerged later in the 20th century, and practitioners have used the term BMP to describe both structural or engineered control devices and systems (e.g. retention ponds) to treat polluted stormwater, as well as operational or procedural practices (e.g. minimizing use of chemical fertilizers and pesticides).

Census Block is the smallest geographic unit used by the United States Census Bureau for tabulation of 100-percent data (data collected from all houses, rather than a sample of houses). The number of blocks in the United States, including Puerto Rico, for the 2010 Census was 11,155,486.Census blocks are grouped into block groups, which are grouped into census tracts. There are on average about 39 blocks per block group. Blocks typically have a four-digit number; the first number indicates which block group the block is in. For example, census block 3019 would be in block group 3.Blocks are typically bounded by streets, roads or creeks. In cities, a census block may correspond to a city block, but in rural areas where there are fewer roads, blocks may be limited by other features. The population of a census block varies greatly. As of the 2010 census, there were 4,871,270 blocks with a reported population of zero, while a block that is entirely occupied by an apartment complex might have several hundred inhabitants. Census blocks covering the entire country were introduced with the 1990 census. Before that, back to the 1940 census, only selected areas were divided into blocks. Census blocks are maintained within the Administration Feature and is dissolved out weekly.

Police Crime Data is a point feature of crime data derived from the County’s E911 system (New World). These points are geocoded to the nearest address block and do not represent an actual address. The public data is limited to 30 days of records.

Polling Places are building locations where voting takes place during an election, typically a location that normally has another function, such as a school.

Satellite communities loosely based off of the USGS Named Places point feature. They are not an official administrative boundary, such as Magistraterial Districts, Voting Precincts, or Zip Code boundaries, but rather a grouping of like cultural and geographic specificity. Hamlets are maintained within the Administration Feature and is dissolved out weekly.Administration is a polygon feature consisting of the smallest statistical areas bounded by visible features such as roads, streams, railroad tracks, and mountain ridges, as well as by nonvisible boundaries such as jurisdictional limits, school district, public safety boundaries, voting precincts, and census blocks.

The Parcels feature is the geographic representation of cadastre records within the County as recorded in deeds and plats. The current parcels set is based off of the 1979 double circle maps by Wingate Appraisal & Mapping and digitized in the early 1990s. The data is continuously updated, as new land records become available. New parcels are added in a “best fit” methodology giving preference to the most current source. This feature is co-managed in AutoCAD and ArcMap. In Arc this polygon feature is part of a Editing topology along with our Zoning feature and our Administration feature. This prevents self-intersection and gaps, while ensuring complete coverage amongst the participating features.
