Zoning
A1
Agricultural District
The A-1 Agricultural District is intended to conserve farmland for agricultural use well into the future and to serve as a holding zone to prevent premature development of land, which could impact the orderly and efficient development of the cities and urbanized areas in Dubuque County. Farmland is one of the County’s most valuable resources. Conserving farmland can help conserve energy, prevent urban sprawl, control public investment in infrastructure, maintain open space and rural character, and reduce conflicts between farming and non-farming uses. The A-1 district allows primarily farming uses and could allow some additional uses that, under special circumstances, may be appropriate in the agricultural district through a Special Use Permit. A zoning change from A-1 to another district should be done in conformance with the comprehensive plan as needs justify the change and when the specific areas can be adequately served by roads, utilities and public infrastructure and facilities.
