Buying Land in Henry County, Iowa

Zoning, subdivisions, and floodplain permits: Planning & Zoning

Henry County's Planning & Zoning department administers the county's zoning ordinance (organized under Title 15, Land Usage, of the county code) along with subdivision review for anyone dividing unincorporated land. The department also administers the county's Flood Plain Ordinance, adopted October 7, 2021, and keeps township-level floodplain maps available to the public. The same staff manage county GIS, so a call to (319) 385-0746 can cover a zoning determination, a subdivision question, or a parcel-mapping request.

Confirm a specific parcel's current zoning district and any overlay -- including whether it falls within the county's Alternative Energy Overlay District, discussed below -- directly with the department before assuming a use or building plan is permitted outright.

Wells and septic: a separate Public Health office, standard Iowa Time of Transfer rules

Private well and septic permitting for unincorporated Henry County is handled by Henry County Public Health rather than Planning & Zoning -- a structural difference from several neighboring Iowa counties that fold everything into one office. All wells in the county require a permit and inspection to construct, and Public Health separately offers well-water testing assistance and limited financial help with well closures and rehabs. As in every Iowa county, a private sewage disposal system serving a property here must be inspected before a sale closes, under the state's 2009 Time of Transfer law.

Wind energy: a large proposed project, a years-long ordinance fight, and a 2025 resolution

Henry County's most consequential recent land-use story starts with a 2021 approach from RWE Renewables, working with Liberty Power, proposing 50 to 90 wind turbines spread across a roughly 30,000-acre footprint in the northern part of the county. About 50 Henry County landowners signed 35-year easement contracts for the project, worth a combined minimum of $77 million in payments, with the developers projecting 200 to 300 construction jobs.

The county's response took years to resolve. Starting around 2022 and intensifying with a formal public-input push in November 2023, the Board of Supervisors worked through repeated drafts of an Alternative Energy Overlay District ordinance meant to govern commercial wind and solar siting -- addressing setbacks, noise limits, shadow flicker, and decommissioning requirements (including a rule treating a turbine as discontinued after 90 days of non-operation). The board also enacted a formal moratorium on new wind (and, separately, solar) zoning requests that ran into September 2025, while ordinance readings drew packed meetings and repeated 2-1 supervisor votes. A document titled as the finalized Alternative Energy Ordinance appears on the county's own Planning & Zoning site dated August 2025, suggesting the multi-year process reached a resolution shortly before the moratorium's scheduled end.

See our dedicated wind-and-solar-leasing page for this county for what the finalized ordinance's terms mean for a nearby or under-easement parcel, and confirm the RWE/Liberty Power project's current status directly with the county rather than assuming either the ordinance's exact final terms or the project's build-out are settled.

Skunk River: recurring, moderate flash flooding worth checking for a specific parcel

The Skunk River crosses Henry County and has produced recurring, generally moderate flooding rather than the catastrophic events documented on some other Iowa rivers -- a July 2024 flash flood raised the river roughly a foot in two hours and covered some roads near Olds, and the river approached flood stage again in July 2025. A major regional flood event in August 2010 hit the broader South Skunk River basin. None of this is the kind of severe, recurring disaster documented for counties directly on the Missouri River, but a parcel near the Skunk River or its tributaries should still have its FEMA flood-zone status and Henry County's Flood Plain Ordinance requirements checked directly with Planning & Zoning.

Farmland values: below the state average for tillable land

Henry County's average farmland value came in around $10,204 per acre in the most recent Iowa State University Land Value Survey, with tillable acreage specifically averaging about $12,503 per acre -- both below the 2025 statewide Iowa average of roughly $11,549 per acre. Treat any county average as a starting point only; a specific parcel's value depends heavily on soil productivity, drainage, and (increasingly, for northern-county parcels) proximity to the wind-easement footprint described above.
