Summary
Union City's Agricultural (A) zoning district exists to shield land suited for farming from incompatible development and prevent premature building until streets, drainage, and utilities can support urban use, per Alameda County, California code.
The agricultural district is included in the zoning title to preserve lands best suited for agriculture use from encroachment of incompatible uses, to preserve in agriculture use land suited to eventual development in other uses, to prevent premature development of certain lands, including lands within the "flood plain," which will eventually be appropriated for urban uses, until the installation of streets, drainage improvements, utilities and community facilities makes orderly development feasible and possible. Change of zoning district from agriculture to any other zoning district shall only be made in general accord with the General Plan. (Ord. 55-64 § 10.1, 1964; Ord. 670-06 § 3, 2006)

Full Breakdown
Union City Municipal Code § 18.48.010 states the Agricultural (A) district is included in the zoning title to preserve land best suited for agricultural use from encroachment by incompatible uses, and to hold land suited for eventual development in other uses until streets, drainage, utilities, and community facilities make orderly development feasible. Rezoning out of agriculture must generally accord with the General Plan. This is a zoning-based land-use buffer, not a right-to-farm nuisance-immunity statute. California's broader right-to-farm protection for agricultural operations runs through state Civil Code § 3482.5, separate from this Alameda County city's zoning code.
Violations & Fines
Developing agricultural-zoned land for an incompatible use, or rezoning without General Plan consistency, can trigger code enforcement action, permit denial, or a stop-work order from Union City's Community Development Department.
