Summary
Marathon County shields farmland from sprawl through its General Agriculture (G-A) and Farmland Preservation (F-P) zoning districts, but county zoning only applies in unincorporated towns that have adopted it, per § 17.101.11.
E.G-A General Agricultural. The purpose of the G-A district is designed to foster the preservation and use of agricultural land related uses and to provide for limited residential uses in a rural environment but not the division of land as classified in § 18.07(2) and (3) into five or more tracts, parcels or lots within a five-year period. This district provides for limited residential development with modest densities that require relatively large land areas that are compatible with the surrounding rural land use activities. The district is intended to provide towns with multiple options to guide growth and development in concert with the comprehensive planning efforts.F.F-P Farmland Preservation Zoning. The intent of this district is to maintain highly productive agricultural lands in food and fiber production by effectively limiting encroachment of non-agricultural development and minimizing land use conflicts among incompatible uses.

Full Breakdown
Unincorporated Marathon County protects farmland through zoning rather than a nuisance-immunity statute. The General Agriculture (G-A) district (10-acre minimum lot, 0.1 dwelling units per acre) and Farmland Preservation (F-P) district (35-acre minimum lot, 0.029 dwelling units per acre) both limit non-farm development and land splits; G-A parcels cannot be divided into five or more tracts within five years. Coverage is not automatic countywide: under § 17.101.11 and Wis. Stat. § 59.69, the Zoning Code takes effect in each town only "upon adoption" by that town's board, and it never reaches inside Wausau, Mosinee, Rothschild, or the county's other incorporated cities and villages.
Violations & Fines
Dividing or developing G-A or F-P land beyond the density and lot-size standards is a zoning violation, enforceable by the Zoning Administrator through citations and Board of Adjustment review.
