Village Conservation Overlay District of Loudoun County, VA (2009)

Data format: SDE Feature Class

File or table name: GISDBB.GISBROW.VCOD_POLY

Coordinate system: Lambert Conformal Conic

Theme keywords: planningCadastre, society, Village, zoning, Village conservation
Abstract: The Village Conservation Overlay District (VCOD) layer is a zoning overlay district of the Revised 1993 Loudoun County Zoning Ordinance (Zoning Ordinance) and identifies thirteen small villages and hamlets outside of the boundaries of Loudoun County's incorporated towns and planned residential communities that contain unique, scenic and historic characteristics that should be maintained and protected. The VCOD is a component of the Official Zoning Ordinance adopted by the Board of Supervisors on January 6, 2003, effective on January 7, 2003, and the Zoning Ordinance further amended on December 6, 2006, and is shown on the Official Loudoun County, VA Zoning Map. The VCOD layer is owned and maintained by Loudoun County, Virginia Department of Building and Development

FGDC and ESRI Metadata:
Metadata elements shown with blue text are defined in the Federal Geographic Data Committee's (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM). Elements shown with green text are defined in the ESRI Profile of the CSDGM. Elements shown with a green asterisk (*) will be automatically updated by ArcCatalog. ArcCatalog adds hints indicating which FGDC elements are mandatory; these are shown with gray text.

Description:
Abstract:
The Village Conservation Overlay District (VCOD) layer is a zoning overlay district of the Revised 1993 Loudoun County Zoning Ordinance (Zoning Ordinance) and identifies thirteen small villages and hamlets outside of the boundaries of Loudoun County's incorporated towns and planned residential communities that contain unique, scenic and historic characteristics that should be maintained and protected.  The VCOD is a component of the Official Zoning Ordinance adopted by the Board of Supervisors on January 6, 2003, effective on January 7, 2003, and the Zoning Ordinance further amended on December 6, 2006, and is shown on the Official Loudoun County, VA Zoning Map.  The VCOD layer is owned and maintained by Loudoun County, Virginia Department of Building and Development

Purpose:
The VCOD is established to recognize the development patterns existing in traditional villages, considered to be valuable heritage resources, and to encourage the retention and reinforcement of the pattern, character and visual identity of the individual village. The data are used extensively for taxation, subdivision review, permitting, and planning.  Although the feature class represents the VCOD, a determination should be requested from the Zoning Administrator to verify whether a particular property is located within the VCOD.

Supplemental information:
The VCOD is mapped coincident with the overlay boundaries adopted by the Board of Supervisors as revised during a joint work session with the Planning Commission on June 22, 2002.  The VCOD boundaries for each twelve existing rural villages in the Rural Policy Area and the Village of Ashburn in the Suburban Policy Area are mapped as specified in the maps attached with the adoption of the Revised 1993 Loudoun County Zoning Ordinance. See the Board of Supervisors worksession documents for more information.  
      Data are stored in the corporate ArcSDE Geodatabase as a polygon feature class.  The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN (vertical datum, if applicable, NAVD88), US Survey foot units.

Process description:
This data set was the result of a process with a shape file created using ArcView 3.0, that was reprojected into HARN83 datum, using ArcToolbox, to a coverage and then to Arc SDE Geodatabase Feature Class. 

All coverages were then reprojected to HARN 83 using the following .prj file specifications: 
        INPUT
        PROJECTION STATEPLANE
        UNITS FEET
        ZONE 5551
        DATUM NAD27 NADCON

        OUTPUT

        UNITS FEET
        FIPSZONE 4501
        DATUM HPGN NADCON
        PARAMETERS END

This dataset was then converted to a feature class in a geodatabase in ArcSDE.
