Summary
Middleton's AGR Agricultural zoning district, established at City of Middleton Municipal Code § 10.02.60, is written to preserve farmland long-term and protect existing farm operations from encroachment by incompatible uses. It caps residential density at one dwelling per 35 gross acres and permits cultivation, intensive agriculture and agricultural services by right, while capping impervious surface at 25 percent.

Full Breakdown
60(3). 60(7) limits residential density to one dwelling unit per 35 gross acres and allows a landowner to split off a one-to-two-acre home lot from a 35-to-70-acre parent parcel while keeping the remainder in agricultural use, specifically to preserve farmland until municipal services justify rezoning to a development district. Dimensional standards in the AGR district are the most generous of any residential-capable district in the code: 50-foot front, side and rear setbacks, a 150-foot minimum lot width, and a 25 percent maximum impervious surface ratio, all sized for working farm parcels rather than subdivided house lots.
02(3) unless the annexation ordinance says otherwise, newly annexed farmland keeps its agricultural protections until the Plan Commission recommends a permanent classification to the Common Council within one year of annexation.
Violations & Fines
Developing AGR land at greater density than one dwelling per 35 acres, or establishing a conditional use such as a campground or composting facility without Plan Commission approval, violates § 10.10.60 of the zoning ordinance. The Zoning Administrator investigates and issues a written notice of violation before referring an uncorrected violation to the City Attorney. Conviction carries a forfeiture of up to $3,500 for a first offense under § 30.04(1)(a), rising to $50 to $3,500 for a repeat violation of the same provision, with each day of continued violation a separate offense under § 30.04(2).
