EASTVILLE, Va. — In a letter to the Mirror, a Northampton County resident is urging local officials and state regulators to closely examine how proposed zoning changes could affect groundwater resources on Virginia’s Eastern Shore, arguing that increased residential density near towns could place additional pressure on the region’s sole-source aquifer.
The concerns come as Northampton County continues considering a proposed zoning text amendment that would create a new Town Edge Residential (TE-R) zoning district, allowing higher-density residential development on land surrounding incorporated towns.
In a letter circulated ahead of a public information session scheduled for Aug. 5 at 6 p.m. at the Eastville Administration Building, the resident contends that the proposal conflicts with the county’s Comprehensive Plan, which encourages directing new development toward areas served by existing municipal water and sewer infrastructure.
The letter argues that because municipalities such as Exmore may lack sufficient water and wastewater capacity to serve future large-scale developments, developers could instead rely on private wells and septic systems for hundreds of new homes.
County officials have previously said the proposed zoning amendment itself does not approve any development. Individual projects would still require rezoning approvals, public hearings, and compliance with applicable state and local regulations.
State groundwater review required for larger subdivisions
The resident also points to a provision of Virginia’s groundwater regulations that applies to larger residential subdivisions located within designated groundwater management areas, including Virginia’s Eastern Shore.
Under 9VAC25-610-44, developers proposing subdivisions with 30 or more lots served by private wells must apply to the Virginia Department of Environmental Quality (DEQ) for a technical groundwater evaluation before final subdivision plat approval. The developer must provide geological information, including a geophysical borehole log, and pay a fee of up to $5,000 for the analysis.
The regulation requires DEQ to recommend which aquifers should be used to minimize impacts on groundwater resources and neighboring well owners. While the recommendation itself is described as “nonbinding,” the regulation also states that developers who choose to drill wells in aquifers inconsistent with DEQ’s recommendation must prepare and obtain approval of a mitigation plan before constructing private wells.
The resident argues that this requirement gives the regulation practical enforcement authority despite the use of the word “nonbinding.”
Saltwater intrusion among long-term concerns
The letter also raises concerns about saltwater intrusion, a long-recognized issue for coastal aquifers.
Hydrogeologists have long warned that excessive groundwater withdrawals from confined freshwater aquifers can allow naturally occurring saltwater to migrate inland, reducing groundwater quality. The Eastern Shore relies heavily on groundwater from the Yorktown-Eastover aquifer system, making long-term management of withdrawals an important consideration for state and local officials.
The resident questioned whether DEQ’s technical evaluations specifically consider chloride concentrations and the potential for saltwater intrusion when reviewing proposed subdivisions.
Questions raised about future developments
The letter further suggests that state regulators should determine whether certain proposed developments expected to rely on private wells have complied with the technical evaluation requirements applicable to larger subdivisions. The Cape Charles Mirror has not independently verified those assertions.
The county has maintained that the proposed Town Edge Residential district is intended to provide additional housing opportunities adjacent to existing towns while requiring individual development proposals to undergo separate public review and approval.
County officials have also emphasized during previous public meetings that no properties would automatically be rezoned under the amendment and that infrastructure, environmental reviews, and state permitting requirements would continue to apply before development could proceed.
Residents will have another opportunity to learn more about the proposed zoning changes during the county’s public information session on Aug. 5 in Eastville.
