Washington Agricultural Lands of Long-Term Significance

Under Washington's Growth Management Act (GMA), RCW 36.70A.170 directs counties and cities to designate agricultural lands of long-term commercial significance and adopt regulations conserving them. RCW 36.70A.060 requires development regulations protecting these designated lands from incompatible uses. Counties typically establish agricultural zoning districts with minimum parcel sizes, restrictions on residential subdivision, and right-to-farm disclosures for new neighbors. Conservation programs including the Voluntary Stewardship Program (RCW 36.70A.700) help balance agricultural viability with critical area protection. Programs like Purchase of Development Rights and Transfer of Development Rights help preserve farmland. Right to Farm protections under RCW 7.48.305 complement zoning to defend established operations.

Inconsistent local zoning may be challenged before Growth Management Hearings Boards under RCW 36.70A.280. Successful petitioners can void noncompliant ordinances and trigger compliance orders.
