Unconstrained Growth in the Rural Policy Area
What Is Happening
-
Between 2003 and 2016, approximately 5,500 new residences were built within
-
Loudoun County’s Rural Policy Area (RPA)—an increase of 75 percent over that period.
-
County projections indicate that an additional 7,500 residences are expected to be built in the RPA by 2040.
-
Under Loudoun County’s current “by-right” zoning, existing regulations would allow for more than 22,000 total residences to eventually be built within the RPA, which would triple the area’s current population.
Why This Matters
-
The Rural Policy Area was established to support agriculture, rural communities, open space, and natural resources.
-
As residential development increases, pressure also grows on roads, water resources, public services, and the rural character that defines much of western Loudoun.
-
Understanding how existing zoning allows for growth helps residents better evaluate long-term impacts and participate in land-use discussions with accurate information.

By-Right Clustered Subdivisions
What This Means
Clustered residential subdivisions are a major contributor to increased residential density in Loudoun County’s rural areas. These developments can result in:
-
Fragmentation and loss of prime farmland
-
Increased traffic on rural roads
-
Changes to community character and quality of life
-
Higher long-term costs to taxpayers
(Related impacts are explained in more detail throughout this Issues section.)
What “By-Right” Development Means
Under Virginia state law, owners of large properties must be given the option to build clustered residential subdivisions on their land. Because this option is guaranteed by law, these developments are referred to as “by-right”—meaning they can proceed without discretionary approval if zoning requirements are met.
How the Review Process Differs Across Loudoun
In eastern Loudoun, most subdivision applications are reviewed by the Loudoun County Board of Supervisors. This review process allows elected officials to consider potential impacts and require mitigation measures that protect the public interest.
In western Loudoun, however, the Board does not have the authority to review or modify the impacts of by-right clustered subdivisions. As a result, developments that meet zoning requirements can move forward without the same level of public oversight.
Why Loudoun Attracts Development Pressure
Loudoun County’s Zoning Ordinance currently allows developers to build two to three times more homes on a given amount of land than is permitted in neighboring counties such as Clarke, Fauquier, and Prince William.
This higher allowable density creates a strong financial incentive for developers from across the region to seek out rural properties in Loudoun for clustered residential development.
Why This Matters
Understanding how by-right development works—and how Loudoun’s zoning compares to surrounding counties—helps residents evaluate growth trends, fiscal impacts, and long-term land-use outcomes in rural areas.
Traffic Congestion
What This Means for Residents
According to the Virginia Department of Transportation (VDOT), each new residence generates an average of ten vehicle trips per day.
As residential development has increased over recent decades, traffic congestion has also increased—particularly on rural roads that were not designed to handle high daily traffic volumes. This has already led to significant congestion and, in some areas, growing community concern and conflict.
What the Projections Show
County projections indicate that 7,500 additional residences could be built within the Rural Policy Area (RPA). Based on VDOT’s estimates, this level of development would generate approximately 75,000 additional vehicle trips per day on Loudoun County roads.
These additional trips would add to existing congestion and further strain rural transportation infrastructure.
Why This Matters Long-Term
Traffic congestion is not just an inconvenience—it can shape long-term land-use outcomes and community character. Proposed road expansions, such as the potential widening of Route 15 north of Leesburg, highlight how increased traffic demand can place pressure on:
-
Local economies
-
Environmental resources
-
Historic landscapes
-
Scenic and cultural assets
-
Overall quality of life
Debates surrounding these projects illustrate the broader consequences of rapid, unplanned population growth in rural areas that lack supporting infrastructure.
Loudoun’s Unique Character and Quality of Life
Much of Loudoun County retains a distinctive character that blends the nation’s early history with an active farming economy and the natural beauty of scenic ridges and waterways.
Residents of the more densely populated eastern parts of the county enjoy easy access to fresh, locally grown farm products; rural wineries and breweries; biking, hiking, and equestrian trails; bed and breakfasts; historic sites; and other predominantly rural attractions.
At the same time, residents of rural areas have convenient access to high-quality shopping, dining, cultural events, and other amenities typically associated with more urban communities.
This balance—offering the best of both rural and urban opportunities—is a key reason Loudoun County is such an attractive place to live. It also helps attract global employers and investors who seek appealing communities for highly qualified employees.
However, the extremely rapid population growth and urban-style development of recent decades increasingly threatens this balance. If left unaddressed, these trends could have serious implications for the quality of life of all Loudoun residents. The following sections outline those implications in more detail.
​
Loss of Farmland
Between 1987 and 2017, Loudoun County lost approximately 72,000 acres of farmland
to residential development—a decrease of one-third.
A critical mass of farmland and active farming operations is essential to support farm
equipment suppliers, feed and fertilizer providers, and other rural businesses. At the
same time, farming in Loudoun would not be commercially viable without access to
these supporting services.
Local farms also provide the foundation and visual backdrop for Loudoun’s vibrant
agritourism sector, which supports thousands of local jobs and generates millions of
dollars in county revenue.
​
​
Cost to the Taxpayer
Providing roads, schools, utilities, emergency services, and other public infrastructure to dense residential development requires significant public investment. In rural areas, the costs associated with this level of development often exceed the tax revenue generated.
As a result, county taxpayers are required to pay the difference.
The county currently estimates that 7,500 additional residences will be built in the Rural Policy Area by 2040. Based on the county’s own fiscal cost models, taxpayers would need to contribute more than $500 million above current tax burdens to cover the operating and capital costs associated with this level of development.
These figures do not include the cost of building roads, which already consume more than half of the county’s capital investment budget. Loudoun County’s FY2019 budget allocated $2.7 million to improve and expand rural roads over a five-year period. Given existing congestion, this amount would likely need to increase if current rural growth projections continue.
Threat to Rural Tourism Businesses
Loudoun’s tourism businesses grew by 4.6 percent in 2017, twice the rate of the U.S. economy as a whole. These small businesses support approximately 17,500 local jobs and rely heavily on the scenic beauty and rural character of the surrounding countryside to attract visitors and increase sales.
In recent years, many new residential developments have been built on hilltops, ridgelines, and along Loudoun’s scenic byways. These developments are increasingly visible from wineries, breweries, bed and breakfasts, wedding venues, hiking and biking trails, and other important tourist destinations.
As development becomes more prominent in these landscapes, it places pressure on the very qualities that draw visitors to Loudoun, potentially undermining the long-term success of the county’s tourism economy.
