Concerns over water supply and zoning regulations took center stage during the Loudoun County Planning Commission Public Hearing on July 29, 2025. Staff raised significant issues regarding a proposed modification that would allow an on-site well to provide potable water for a development project in the southern portion of the county.

The applicant's hydrogeologic study suggested that the well could yield 52 gallons per minute for up to 14 hours a day. However, a county consultant noted that while the study met county standards, it lacked clear evidence that the well could sustain this output over the long term. There are fears that the well could negatively impact nearby supply wells, leading to greater drawdown and potential water shortages for surrounding residents.

Staff emphasized that under the revised 1993 zoning ordinance, any modifications must demonstrate innovative design or improvements over existing regulations. They questioned how the proposed on-site utilities would meet these criteria.

Ultimately, staff could not support a recommendation for approval to the Board of Supervisors, citing inconsistencies with the 2019 general plan and insufficient mitigation of impacts to nearby neighborhoods. The proposed changes were seen as detrimental to the county's vision for sustainable development.

As the meeting concluded, the implications of these discussions highlighted the ongoing challenges Loudoun County faces in balancing development with community needs and environmental sustainability.
