Abstract:

Small scale digital data consists of the Prime Farmland Soils in the AR-1 and Rural AR-2 Zoning Districts of the Rural Policy Area that were identified with the adoption of ZOAM-2020-0002 in June 2024 with an effetive date of March 12, 2025. They include the following soil types; 3A, 13B, 17B, 23B, 28B, 31B, 43B, 45B, 55B, 71B, 76B, 90B, 93B, 94B, 95B.

Purpose:

Digital data are used to identify the mapping unit potential for a variety of uses in large areas, such as agriculture drainfield suitability, construction concerns, or development possibility. This material is intended for planning purposes, primarily to protect and conserve agriculturally productive prime agriculture soils in the AR-1 & AR-2 Zoning Districts only & identify their distribution & extent. The information in this guide is NOT intended for use in determining specific use or suitability of soils for a particular site, due to mapping scale of 1:12000.

Supplemental Information:

Fieldwork 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.

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.

Maintenance and Update Frequency:

The data are updated as field site inspections or interpretation changes occur.

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.
