Unincorporated Washington County controls development intensity through one-unit-per-acre density rather than an impervious-coverage percentage. Fayetteville and Springdale cap building and paved coverage by zoning district and apply stormwater rules to heavily paved lots.
Rather than a countywide lot-coverage percentage, Washington County limits how densely unincorporated land develops by defaulting parcels to one dwelling per acre and reviewing divisions through the Planning Board under Chapter 11. Large minimum lots keep impervious coverage low, and septic-system sizing further constrains what a rural lot can support. Cities set the real coverage caps: Fayetteville's Unified Development Code limits building and impervious coverage by district and requires low-impact drainage and stormwater controls, and Springdale applies its own zoning coverage limits. Permeable surfaces may earn partial credit in some city calculations. Confirm your district's maximum with the local planning office.
Exceeding a city's coverage limit requires removing impervious surface or obtaining a variance, and may trigger stormwater review. County plats below minimum lot size are rejected by the Planning Board.
