The zoning layer constitutes the official zoning map for Loudoun County and is a component of the official zoning ordinance. It reflects expiration of grandfathering provisions of the 1972 Zoning Ordinance for certain proffered PD-H and R-Districts created prior to June 16, 1993. The zoning data is owned and maintained by Loudoun County, Virginia Department of Building and Development. Purpose: The purpose is to facilitate the administration of the zoning ordinance. The data are used extensively for taxation, subdivision review, permitting, and planning. Supplemental Information: Boundaries generally follow parcel lines, although there are several exceptions. The zoning data does not include zoning overlay districts, such as LDN, Floodplain, Quarry, or Mountainside Overlay Districts. Although the layer represents the official zoning map, a determination should be requested from the Zoning Administrator to verify zoning for a particular property. Data are stored in the corporate ArcSDE Geodatabase as a feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN. It is also important to note that in order to determine the Zoning Ordinance Amendments (ZOAMs) that are applicable to a particular parcel governed under the Revised 1993 Zoning Ordinance located within the Route 28 Tax District, the ZO_ZONE_DATE, Opt-In Letter, proffer statement, rezoning plat and/or concept development plan should be consulted as applicable. For an official determination regarding the applicable zoning, zoning ordinance text and/or whether proffered conditions may apply to a certain property, please contact the Zoning Administrator in the Department of Building and Development. Data are stored in the corporate ArcSDE Geodatabase as a feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN.

Completeness Report: Features may have been eliminated or generalized due to scale and intended use. To assist Loudoun County, Virginia in the maintenance of the data, please provide any information concerning discovered errors, omissions, or other discrepancies found in the data.
