Summary
Black Hawk County Code Section 18.75.040 blocks nuisance lawsuits against a farm operating in an agricultural zoning district, using accepted practices, since before the alleged nuisance arose. Neighbors who move in next to an established farm inside an agricultural district cannot later sue over routine farm noise, odor or dust.
No nuisance suit, action or proceeding, alleging that an agricultural operation is a public or private nuisance, shall be maintained in the district court if: A. The agricultural operation was conducted within an agricultural district at the time the nuisance was alleged to have arisen; and B. The agricultural operation was conducted in accordance with accepted agricultural practices at the time the nuisance was alleged to have arisen; and C. The agricultural operation established date of operation was prior to the time the nuisance was alleged to have arisen; and D. Either (1) the agricultural operation began prior to ownership, occupancy or use of land within an agricultural district by a person alleged to have suffered injury as a result of the agricultural operation, or (2) a person alleged to have suffered injury as a result of an agricultural operation suffered the injury after the adoption of the ordinance codified in this chapter and as the owner, occupier or user of lands within an agricultural area.
Full Breakdown
030 when the nuisance was alleged to arise; it followed accepted agricultural practices at that time; its established date of operation predates the alleged nuisance; and either the farm predates the complaining neighbor's ownership or occupancy of land in the district, or the neighbor's injury occurred after the county's 1982 right-to-farm ordinance took effect while that neighbor already owned or occupied land in an agricultural area. The protection is not absolute. 050 carves out five exemptions: negligent agricultural operations, damage from air, land or water pollution, changes to a stream or watercourse, increased flood heights or velocities from floodplain encroachment, excessive soil erosion, and any operation located inside an incorporated municipality.
060 also lets sellers and lenders attach a standard notice to land sale contracts and building permits inside or near an agricultural district, warning buyers that under Section 4 of the county's Right to Farm Ordinance, established farm operations are shielded from nuisance suits over noise, odors, dust, machinery, manure storage or chemical application. 070.
Violations & Fines
An agricultural operation loses BHCC 18.75.040's nuisance-suit shield if it operates negligently, pollutes air, land or surface or subsurface water, alters a stream's condition, worsens flooding by encroaching on the floodplain, causes excessive soil erosion onto a neighbor's land, or sits inside an incorporated city, all exceptions listed in BHCC 18.75.050. Any of those conditions lets a nuisance suit proceed in district court.
