Summary
Whatcom County's Agriculture (AG) zoning district makes farming the county's highest-priority land use: density is capped at one dwelling per 40 acres and lot coverage at 25 percent so the commercial farmland base stays intact. WCC § 20.40.010 ties the district directly to Chapter 14.02 WCC, the county's Right to Farm ordinance, to limit conflicts with neighboring zones.
The primary purposes of this district are to implement the agricultural designation of the Comprehensive Plan, established pursuant to RCW 36.70A.170, preserve, enhance and support the production of food and fiber in Whatcom County, to maintain a sufficiently large agricultural land base to ensure a viable agriculture industry and to maintain the economic feasibility of supporting services. Whatcom County supports agricultural activities as the highest priority use in the Agriculture District, with all other uses being subordinate to agricultural activities. Whatcom County seeks to minimize conflict with surrounding zoning districts, in conjunction with Chapter 14.02 WCC, Right to Farm.
