Planning board splits on 'road-split' minor subdivision rule; opts to brief full board and commissioners

The Union County Planning Board discussed several proposed changes to minor-subdivision rules on June 9, including whether a parent parcel bisected by a state-maintained road should count as two separate parent tracts (potentially allowing separate minor subdivisions on each side) and whether to reset the county's 1978 'lot of record' reference to a more recent period.

Staff explained the current ordinance treats each side of a state-maintained road as a separate parent tract for subdivision counting, which can allow up to eight lots per side under the county’s definition of a minor subdivision. Proponents said treating split parcels separately can compensate owners disadvantaged by road takings; opponents argued it creates a loophole allowing developers to avoid major-subdivision requirements and environmental review.

Board members also considered peer-county practices. Staff cited examples ranging from counties that limit minor subdivisions to three–five lots without new infrastructure to others that allow up to 10 or even 20 lots but restrict new infrastructure or impose reset periods (three years, five years, or 10 years). Several members floated a compromise — raising the minor threshold to 10 but limiting the effect of road splits so the total allowed remains constrained — but members agreed to delay final recommendations until the full planning board could meet.

The board asked staff to present the discussion and any consensus guidance to the Board of County Commissioners, noting that final text amendments would return to the planning board. Staff also reviewed family-subdivision approaches from other counties (lineal-descendant limits, minimum lot sizes, easement access, ownership-holding requirements such as a three-year ownership period), and cautioned about enforcement challenges and private-easement maintenance if such programs are adopted.

Why this matters: changes to minor-subdivision rules affect housing production, developer behavior, environmental review thresholds and infrastructure requirements. The board agreed these topics deserve broader participation and will reconvene when a full planning board is present before forwarding recommendations to the commissioners.

Next steps: Staff will present the recorded discussion and possible options to the Board of County Commissioners and bring the item back to the planning board when the full membership is present.
