This map provides the location of the original land grants within present day Loudoun County from the early 1700s to early 1800s. To view a list of sortable attributes of the information, please click on the Table button in the upper right corner of the map. For additional details, please visit here.

These are the original grantings of land within the Northern Neck Proprietary by Thomas, the 6th Lord of Fairfax and/or his agents until the mid 1780s during the settlement of Virginia. The map shows the approximate location of the original land grant as well as information on the grantee, the acreage of the grant (as calculated using the GIS), the year, and additional comments. The map is intended for historical reference only, as insufficient and incomplete original boundary surveys have resulted in potential inaccurate boundaries.

The original research for all of the land grants mapped in this application was completed by historian Wynne Saffer. They were originally mapped on USGS Quadrangles at a scale of 1:24000, then scanned to a digital file and the boundaries digitized by the Loudoun County Office of Mapping and Geographic Information staff.

The orginial land grant research is located at Thomas Balch Library. The land grants can be viewed on microfilm using the Record Number as a reference. This map is also located on the Office of Mapping and Geographic Information online map gallery, which can be found here.

This feature class contains all the county owned and leased property data of Loudoun County, VA as of April 2024. It is comprised from internal data and information sources combined with parcel data.

Loudoun County annually obtains leaf-off, aerial imagery in the spring. Since 2004, the County has utilized this imagery to support the development of an annual digital orthophoto base. In 2024, the imagery was captured with a Vexcel Ultracam Eagle digital camera, in 4-band (R,G,B, and NIR) format. These files contain 1-foot ground-resolution, 8-bit, 4-band orthorectified aerial image map products in GeoTIFF version 6.0 file format. GeoTIFF files are uncompressed raster images complete with TFW coordinate information. The aerial imagery project encompasses the entire land area of the County of Loudoun, VA. Images were flown during leaf-off conditions and cover 5000' by 5000' and are tiled according to the VBMP 200-scale gridding schema (Virginia Geographic Information Network).

More MetadataAbstract: The general soil association map outlines broad areas which have distinctive patterns in landscape and general geographic appearance. Each of the soil associations has a unique set of features which effect general use and management including shape and length of slope; width of ridgetops and valleys; frequency, size, and direction of streams; type of vegetation, rate of growth; and agriculture. These differences are largely the result of broad differences in kinds of soils and in the geologic materials from which the soils formed. A mapping unit typically consists of one or more major soils with minor soils, and is named for the major soils. This map shows, in small scale, a summary of the information contained on the individual detailed soil maps for Loudoun County. Because of its small scale and general soil descriptions, it is not suitable for planning small areas or specific sites, but it does present a general picture of soils in the County, and can show large areas generally suited to a particular kind of agriculture or other special land use. For more detailed and specific soils information, please refer to the detailed soils maps and other information available from the County Soil Scientist. Digital data consists of mapping units of the various soil types found in Loudoun County, Virginia. The data were collected by digitizing manuscript maps derived from USDA soil maps and supplemented by both field work and geological data. Field work for the soil survey was first conducted between 1947 and 1952. Soils were originally shown at the scale of 1:15840 and then redrafted by the County soil scientist to 1:12000; the data were redrafted a final time to fit Loudoun County's base map standard of 1:2400. Although the current data rely heavily on the original soil survey, there have been extensive field checks and alterations to the soil map based on current soil concepts and land use. The data are updated as field site inspections or interpretation changes occur.Purpose: Digital data are used to identify the mapping unit potential for a variety of uses, such as agriculture drainfield suitability, construction concerns, or development possibility. This material is intended for planning purposes, as well as to alert the reader to the broad range of conditions, problems, and use potential for each mapping unit. The mapping unit potential use rating refers to the overall combination of soil properties and landscape conditions. The information in this data set will enable the user to determine the distribution and extent of various classes of soil and generally, the types of problems which may be anticipated. HOW NOT TO USE THIS INFORMATION The information in this guide is NOT intended for use in determining specific use or suitability of soils for a particular site. It is of utmost importance that the reader understand that the information is geared to mapping unit potential and not to specific site suitability. An intensive on-site evaluation should be made to verify the soils map and determine the soil/site suitability for the specific use of a parcel. The original Soil Survey was written for agricultural purposes, but the emphasis has shifted to include urban/suburban uses. The Revised Soil Survey is currently under technical review and is expected to be published by 2006.Supplemental information: The Interpretive Guide to the Use of Soils Maps; Loudoun County, Virginia contains more detailed soils information. Data are stored in the corporate GIS Geodatabase as a polygon feature class. The coordinate system is Virginia State Plane (North), Zone 4501, datum NAD83 HARN.

Street centerline was originally developed from the road features on the County's 1:2400 base map. Both address range and a link to street names are included as data attributes. The current data is collected from recorded plats in DXF format or is digitized from plats. The data covers the entire County as well as the incorporated Towns. Purpose: The street centerline coverage was originally developed to support addressing. Fire & Rescue Services and the Sheriff's Office use the address range information for Emergency 911 dispatching; it is also used to update U.S. Census Bureau Tiger data in support of the decennial census. Supplemental Information: Centerline data are maintained from plats and site plans prepared by engineering and surveying firms. Although street centerline is the most current of the County's street data, deviation in construction after plat submittal and recordation may cause centerline to differ from similar County layer, road casing. Centerline contains the most current data; road casing is spatially more accurate because it is updated photogrammetrically. These data are not intended to be used for local surveys or at a scale larger than 1:2400. 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. Maintenance and Update Frequency: Data is updated on a daily basis.

More MetadataAt the July 3, 2012 Loudoun Board of Supervisor's Business Meeting, the Board agreed to be a funding partner with the Metropolitan Washington Airports Authority (MWAA) and Fairfax County for the Phase II extension of Metrorail to Dulles Airport and Ashburn. Loudoun County’s rail service districts were established on December 5, 2012 to fund the construction and maintenance of the stations, rail line, and rail related facilities and services. All parcels in the districts, residential and commercial, have a special property tax rate for funding of the rail. Tax collection for the districts is for Tax Year 2013 and future years.The boundaries of the Metrorail Service District were defined using physical features such as major roads and streams within two miles of stations. In some cases, parcel boundaries were used to develop the tax district boundary. The Route 606/Airport and Route 772 station service districts were defined using half-mile radii around the four proposed rail stations in or near Loudoun County: 1) Route 772, 2) Route 606, 3) Dulles Airport, and 4) Route 28. These radii were used as approximate guidelines. At the time the districts were established, the districts encompassed primarily commercial land. Only a few existing residential units were included within these districts at the time the districts were established.The features the boundaries follow may have been generalized due to scale and intended use.

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.
