This layer contains data defining the exterior boundaries of subdivided land within Fairfax County, Virginia.

The polygons portrayed on this layer define the second portion of the County's Parcel Identification Numbering system (Map / Subdivision / Block / Parcel). Information portrayed on this layer was initially derived from the ink-on-mylar property maps maintained by the County since the early 1960s.For more information go to the Geospatial Property Data Guide.Contact: Fairfax County Department of Information Technology GIS DivisionData Accessibility: Publicly AvailableUpdate Frequency: DailyLast Revision Date: 1/1/2000Creation Date: 1/1/2000Feature Dataset Name: GISMGR.PARCELSLayer Name: GISMGR.SUBDIVISIONS

This feature class represents the smallest geographic unit located in development centers as defined by the Fairfax County Comprehensive Plan. The Comprehensive Plan text refers to these areas as land units, sub-units, districts, subareas, sub-blocks, and suburban neighborhoods, depending on what section of the Plan they are located. For the purpose of this feature class and metadata, these areas are referred to generically as a geographic unit.

During a ten-year observation period three 0.1 ha plots in Hemlock Overlook Regional Park, Fairfax County, VA, were regularly sampled. Student observers recorded and identified to species wherever possible, all trees with a DBH of 3cm or greater in these plots. In total there were 94 sampling events across the ten years with a total of 4,536 trees counted and measured. Of the recorded trees, the most frequently sampled trees were beech (Fagus grandifolia), with 1,681 records and the least frequently recorded trees were maple (Acer spp.) with 410 records. This dataset adds to the literature a longitudinal consistent sampling dataset that can be used for forestry and forest ecology research.

Geographic boundary, portraying extent and limits of land recognized as Fairfax County, Commonwealth of Virginia. Defined in part by both physical features (Potomac and Occoquan Rivers), and monumented legal boundaries.

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.

This layer contains boundaries of questionable cut properties in the cadastral data. These are properties that were split but did not go through the subdivision control process. These are being monitored and when some sort of redevelopment occurs that requires a line change and new parcel number they are being corrected.Contact: Fairfax County Department of Information Technology GIS DivisionData Accessibility: Publicly AvailableUpdate Frequency: DailyLast Revision Date: 1/1/2000Creation Date: 1/1/2000Feature Dataset Name: GISMGR.PARCELSLayer Name: GISMGR.QUESTION_PARCELS

This layer contains polygons that show the public rights of way. Right of way is defined as area or path that is accessible for people to pass through. Right of ways are normally found where roadways exist to allow for the public to travel. Right of way is the land that is not part of a parcel or common area in the GIS data.Contact: Fairfax County Department of Information Technology GIS DivisionData Accessibility: Publicly AvailableUpdate Frequency: DailyLast Revision Date: 1/1/2000Creation Date: 1/1/2000Feature Dataset Name: GISMGR.PARCELSLayer Name: GISMGR.RIGHTSOFWAY
