Planning staff present comprehensive-plan update; ADUs, broadband, water and future land‑use corridor draw concentrated debate

Planning staff presented a draft update to Warren County’s comprehensive plan at the joint meeting on Nov. 12, emphasizing a guidance document the county intends to adopt to guide land use, infrastructure and community facility priorities for the next 10–20 years.

Kelly Lawson (planning staff) summarized the update process and public outreach: the update builds on the 2013 plan and the 2018 strategic vision with background data from the U.S. Census, Weldon Cooper Center and other sources, citizen surveys (several hundred responses) and VDOT review. Staff told the board the plan aims to balance growth, preserve rural character, and address housing and infrastructure priorities.

Key items discussed:

- Accessory Dwelling Units (ADUs): Staff proposed opening ADUs to agricultural and rural residential zoning districts as a long-term housing tool. Draft ordinance language under discussion suggested a minimum lot-size threshold; planners said 3 acres for attached ADUs and 5 acres for detached ADUs were under consideration after community feedback that an initial 2-acre concept was too small in many rural septic/well settings. Planners stressed that ADUs would be subject to health-department requirements on wells and septic and that ordinance provisions could include size limits and permit/permit-fee approaches rather than full conditional-use permit processes.

- Water, sewer and infrastructure: The plan updates infrastructure priorities and notes options for water supply (including revisiting McKay Springs, connections with Frederick County, and exploration of quarries as storage options). Staff noted VDOT review on transportation chapters was near completion and that FEMA Community Rating System changes were included to support flood-insurance class improvements.

- Broadband and cellular: The draft adds language encouraging broadband and cellular expansion. Staff flagged limitations in federal coverage data and cited regional NSVRC plans and recent state-funded initiatives to extend fiber.

- Future land‑use corridor: Staff showed a proposed rebalancing for the Route 522/340 corridor to preserve some sensitive flood plain areas as conservation/open space while identifying other adjacent parcels with industrial/commercial potential. A property owner requested reclassification of several parcels to rural residential; several supervisors argued the corridor lands are among the county’s last commercial/industrial opportunities and urged caution before converting potential revenue-producing land to housing.

- Short‑term rentals and housing: Commissioners debated whether short-term rentals were materially affecting housing inventory and suggested adding language calling for a study of short-term rental impacts on long-term housing availability and school/district impacts.

Board and commission members asked planners to provide additional maps, clarify ADU septic and well constraints and provide probable counts and impacts under each acreage threshold. Staff agreed to refine the draft and append survey results, maps and VDOT letter before public hearings. The planning commission planned a public hearing at its next meeting, and staff said the board would receive the item after the planning commission completes its review.

Ending: Staff will return with revised language, maps and VDOT approval letter; the planning commission will hold a public hearing and then forward recommendations to the board. No adoption vote occurred at the work session.
