DATA CENTER OPPORTUNITY ZONE OVERLAY DISTRICT (DCOZOD)

[Municode: Section 32-509] [Map]
On August 4, 2015, the Board of County Supervisors adopted Resolution 15-508 to support protection of private property, historical resources and commercial interests from potential negative impacts of new high voltage overhead transmission lines. As part of that resolution, the Board of County Supervisors declared its intent to initiate a zoning text amendment to incorporate appropriate zoning requirements for data centers which would address the infrastructure necessary to support such uses and the potential impacts to other properties. The resolution also noted that this amendment should continue the County's efforts to advance commercial and industrial development.

DOMESTIC FOWL OVERLAY DISTRICT (DFOD)

[Municode: Section 32-508] [Map]
The purpose of creating a domestic fowl overlay district is to permit the keeping of chickens, pigeons, doves and other domestic fowl on lots with a rural and semi-rural character that also contain a dwelling unit as a principal use. The keeping of domestic fowl is permitted by right on A-1 zoned properties and on SRR zoned properties by Special Use Permit on a lot with or without a principal residence within this district. To ensure reasonable protection of health, safety and welfare associated with the keeping of domestic fowl, development regulations specific to this district are provisioned. The keeping of domestic fowl is not permitted outside of the Domestic Fowl Overlay District, except on A-1 zoned lots of ten (10) acres or larger. 

FLOOD HAZARD OVERLAY DISTRICT

[Municode: Section 32-501]
The Board of County Supervisors has found as fact that the flood hazard areas of the County are subject to periodic inundation which results in the loss of life and/or property, health and safety hazards, disruption of commerce and other governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base. As such, the Board has chosen to delineate this district in accordance with the areas of the County subject to inundation by the 100-year flood (a flood that, on average, is likely to occur once every 100 years). Areas of the County shown to be subject to this flood were found on the basis of the Flood Insurance Study (FIS) for Prince William County (prepared by FEMA, dated Jan. 1, 1995), engineering studies prepared by the U.S. Army Corps of Engineers, the U.S. Soil Conservation Service, and other public and private sources.

HIGHWAY CORRIDOR OVERLAY DISTRICTS (HCOD)

HISTORIC OVERLAY DISTRICT (HOD)

[Municode: Section 32-501] [Map]
A Historic Overlay District is created for the purpose of imposing special requirements in addition to the requirements pertaining to the underlying zoning district in designated areas of the County, in order to protect and perpetuate those areas or structures which have been designated as being of significant historic, architectural, or cultural interest. Regulations imposed in such a district are intended to: 1) protect against destruction of, or encroachment upon such historic resources; 2) encourage uses which will continue to preserve them, and; 3) prevent the creation of adverse environmental influences. Exterior alterations to buildings within the historic overlay district are administered by the Architectural Review Board. 

REDEVELOPMENT OVERLAY DISTRICTS (ROD) 

• Area predominantly developed and with few vacant sites;
• Number of developed parcels exceeding one hundred (100);
• Developments are predominantly residential;
• Average age of structures is twenty-five (25) years old or more;
• Developments lacking compliance with current standards and consequently unable to expand;
• Area visually unattractive because of the proliferation of nonconforming signs, overhead utility lines, poorly maintained buildings and parking lots, and sparse landscaping;
• Developments are accessed by numerous and closely spaced driveways connecting to the main highway;
• Area in need of economic incentives such as grants, public/private partnerships, and special financing programs to prevent its further deterioration. 

TECHNOLOGY OVERLAY DISTRICT (TEOD)

[Municode: Section 32-506] [Map]
The Technology Overlay District (TeOD) is intended to promote harmonious development which is conducive to establishing and maintaining collaborative public-private research partnerships. To achieve this intent, the district will be located adjacent to a major public institution, such as an institute of higher education. The district will primarily promote those nonresidential uses that support and enhance the activities of the major public institution and that respond to the County's targeted industries program. In addition, the district will provide for residential dwelling units for people primarily associated with the targeted industries and the major public institution. The district will also provide for compatible nonresidential service uses needed to support the overall public-private research environment. 
The TeOD is specifically intended to provide for primary employment uses consistent with the county's targeted industry program. These primary employment uses include research facilities, offices, prototype production facilities, and other light manufacturing operations that require the continual or recurrent application of advanced research.
Special requirements in addition to or in place of the requirements of an underlying zoning district may be imposed to achieve the desired goals set forth above. Such requirements are intended to promote harmonious development by: 

• Ensuring that individual properties are developed so as to preserve existing natural topographical features and wooded areas;
• Promoting generous landscaping, building and parking lot setbacks;
• Encouraging innovative site designs which include continuity of architectural and design themes while allowing flexibility;
• Preventing the creation of or reducing the presence of adverse environmental influences such as noise, traffic, fumes, waste, unsightly views (i.e., outside storage, open off-street parking areas), and excessive lighting and signage;
• Encouraging development which results in a campus-like setting in developed areas and a park-like setting in preserved open space areas; and,
• Encouraging non-motorized access between individual properties through the development of a comprehensive sidewalk/trail system.
