About Site Plans
A site plan is a detailed engineering drawing of proposed improvements to a given lot. A site plan usually shows a building footprint, travelways, parking, drainage facilities, sanitary sewer lines, water lines, trails, lighting, and landscaping. The specific requirements are outlined in Chapter 8 of the Loudoun County Facilities Standards Manual (FSM).
A site plan is required by Section 6-701 of the Loudoun County Zoning Ordinance for development of any land which falls into the following categories:
- All uses on a commercial or industrial zoned property;
- All permitted uses in the residential districts, except for agricultural structures and single-family detached dwellings, duplex dwellings, townhouses and accessory uses and structures allowed by the Loudoun County Zoning Ordinance;
- Those special exception uses and structures which require a site plan;
- Any development in which any required off-street parking space is to be used by more than one establishment;
- When an alteration or amendment is proposed to the site improvements or design of a previously approved site plan, unless site plan amendment criteria can be met; in that case, a site plan amendment application may be filed;
- When an existing residential use is proposed for a change to a commercial, industrial, or multi-family residential use;
- All public buildings and institutions;
- All other uses involving a building required to be reviewed by the Planning Commission under Section 15-1.456 of the Code of Virginia as amended.
Why do I need a Site Plan?
Loudoun County requires site plans for property development to insure that development occurs in an orderly manner and that standards are followed for the protection and promotion of the general health, safety, and welfare of the county's residents. The site plan process encourages attractive and harmonious development for the ultimate site users and for the county as a whole. The approved site plan will be used by the contractor responsible for construction of the site improvements.
