Commission reviews land-use maps and housing options — ADUs, cluster housing, land trusts and conservation bonuses discussed

At the Dec. 10 workshop, planning staff presented proposed future-land-use map updates and a suite of housing-policy options intended to help Powhatan meet its strategic goals for diverse housing and economic opportunity.

Staff described five future-land-use categories (economic priority, economic opportunity, gateway business, industrial and village) and showed colored and aerial map views for commissioners to consider parcel-by-parcel. Commissioners discussed consolidating some categories based on parcel acreage thresholds (for example, parcels under 10 acres remaining commercial-only while parcels 10–75 acres could be mixed-use) and emphasized the critical role of water and sewer availability in enabling higher-density housing.

On housing tools, staff said Powhatan’s ADU ordinance is permissive and recommended modestly increasing allowed ADU size (from 35% or 50% of the main dwelling to slightly larger percentages) to expand capacity. The commission discussed cluster housing as a targeted option in growth areas with public utilities, with shared open space and conditional-use review for design standards. The concept of a land trust to secure permanently-affordable units was raised as an aspirational, non-regulatory tool: "It doesn't necessarily have to be an ordinance... It doesn't have to be anything in our code or anything," staff said, describing land-trust set-asides as a voluntary option for upzoning proposals.

Staff also reviewed conservation-subdivision rules and the work group’s recommendation to allow a larger density bonus (example: up to 85%) while excluding floodplain and wetlands from the density calculation; bonuses above by-right levels would likely require conditional-use permit review, commissioners said. Several commissioners urged caution so that conservation tools do not unintentionally erode agricultural land protections.

Next steps: staff will circulate the maps used in the meeting (colored and aerial views) for commissioners to annotate and agreed to reconvene the group for a focused mapping session around the date discussed at the meeting (referred to in the workshop as 'the 20th').
