Zoning: a comprehensive-plan rewrite, now largely resolved for wind energy

Unincorporated Humboldt County is governed by Ordinance No. 26, the Zoning Ordinance for the Unincorporated Portion of Humboldt County, administered by a county Zoning Administrator (Ben Ulrich, based at 2221 220th Street, Humboldt, IA 50548, (515) 332-2366). What's specific to Humboldt County right now is that this framework has been mid-rewrite: the county's draft Comprehensive Plan had its first reading on March 30, 2026, part of a broader planning process that also produced a new Commercial Wind Energy Ordinance (No. 77), adopted unanimously by the Board of Supervisors on July 13, 2026.

That new wind ordinance responds directly to a named, active project: RWE's proposed 175 MW Humboldt Wind, sited in the southeast quadrant of the county. A prior countywide moratorium (Resolution 2024-01-07, effective January 2024) had specifically frozen new applications for commercial wind, solar, and pipeline/transmission siting -- not zoning generally -- while the county worked out its rules; Ordinance 77's adoption resolves that for wind, though RWE's attorney argued during the adoption hearing that the ordinance's setback requirements function as a de facto prohibition on the project, a dispute that remains unresolved. See our dedicated wind-solar-leasing page for this county for the full history, the ordinance's specific provisions, and what's still unconfirmed (including whether the moratorium's solar and pipeline provisions were lifted alongside the wind rules). For any other zoning determination, subdivision approval, or general permitted-use question, confirm current status directly with the Zoning Administrator's office, since the broader comprehensive-plan rewrite may still affect other parts of the ordinance.

Wells and septic: a regional partnership with Wright County

Humboldt County's environmental health services -- septic system design review and permitting, enforcement of the Iowa DNR's Chapter 69 private sewage disposal rules, private well questions, and review of Time of Transfer inspections required at the point of certain real estate sales -- are handled through a joint arrangement with Wright County Environmental Health rather than a standalone in-county department. The current contact is Sandy McGrath at the Wright County Health Department, 115 First Street SE, Clarion, IA 50525 (cell (515) 851-8878). If you're closing on a property here, confirm early whether a Time of Transfer inspection is required and build in extra time for scheduling given the shared, regional nature of this office.

Floodplain: a new record crest on the Des Moines River in June 2024

Humboldt County sits at the confluence area of the East and West Forks of the Des Moines River, and that geography produced a genuinely historic flood in June 2024. The West Fork Des Moines River at Humboldt reached a new record crest of 16.99 feet on June 27, 2024, breaking the previous all-time record of roughly 15 feet 4 inches set in 1969 (a record that had also stood through the major 1993 Midwest flood). The East Fork Des Moines River crested near 22 feet the same week, flooding Dakota City's park; Dakota City itself sits on relatively high ground and is not generally affected by flooding at that stage, but residents along River Drive built sandbag levees and reported sheds and docks taking on water. Because this level of flooding exceeded the county's prior 55-year record, treat any older flood-risk assessment or FIRM panel predating 2024 with real caution. See our dedicated flood-zones page for this county for the full timeline and what it means for evaluating a specific parcel.
