Detailed entries

Adair County

• Type: County
• Status: 🟢 Active
• Date enacted: 2026-03-18, per signed Adair County Board of Supervisors minutes: Resolution #2026-26 adopted by unanimous 5-0 roll call (Hoadley, Baier, Wedemeyer, Christoffersen, Walker all aye).
• Normalized date: 2026-03-18 (exact)
• Duration: Not captured in news report; resolution text not yet obtained
• Current end date: —
• Sectors: data center
• Moratorium ID: ia-adair-county-2026
• Legal basis: Resolution #2026-26, "Resolution to Establish a Temporary Moratorium on the Construction of Data Centers, High-Density Computing Facilities, and Battery Storage Facilities in the Unincorporated Areas of Adair County, Iowa," adopted March 18, 2026 by unanimous 5-0 roll call.
• What prompted it: Proposed 765 kV MISO transmission line, land negotiations in the Hebron area, and concern that data centers require large amounts of electricity and water.
• Affected projects: Applied Digital interest in a 200 MW data center near Adair reported in Clarke County coverage; no Adair County project approval record captured.

Official minutes through 2026-07-15 show a draft data center ordinance was discussed (March 25, 2026 meeting: Supervisor Hoadley presented an AI-drafted ordinance for County Attorney review) but never formally adopted, so Resolution #2026-26's temporary moratorium remains in force.
• Outcome: Supervisors continued reviewing a draft data center ordinance after adoption of the moratorium. The draft would require data-center equipment to be housed in permanent structures on foundations, not shipping containers or similar temporary structures (March 25, 2026 Western Iowa Today: "No action was taken on the ordinance today" — confirms ordinance was still in draft a week after the moratorium passed).

Franklin County adopted two further ordinances (2026B and 2026C) on 2026-07-14 covering Commercial Bitcoin Installation, Commercial Batteries, solar, and nuclear as conditional uses, but neither addresses "data center" development, so the moratorium's early-termination trigger has not been met.
• Outcome: No replacement ordinance identified.

Ida County

• Type: County
• Status: 🟢 Active
• Date enacted: 2026-06-30 (news-reported; not primary-sourced)

Jackson County

• Type: County
• Status: 🟢 Active
• Date enacted: Three documented adoptions in the captured record: (1) 2024-09-17 — Resolution #1066-09-17-2024 — "Resolution Approving Moratorium on Data Mining Facilities" (signed copy in record), originally through 2025-06-30 (text reads "for a period of months through June 30, 2025"). (2) 2025-09-09 — Resolution #1142-09-09-2025 — second moratorium re-established at the September 9, 2025 BoS meeting (signed minutes capture the motion and adoption). The interim 2025-03-25 "Resolution #1105-03-25-2025" referenced in earlier project notes is not corroborated in the captured Jackson County record and may have been a transcription of the 2024 resolution number; treat as ****.
• Normalized date: 2024-09-17 (exact)
• Duration: First instance (Sept 17, 2024) ran through June 30, 2025 (Resolution #1066-09-17-2024 text). Second instance (Sept 9, 2025) runs through August 31, 2026 unless ended sooner by board action (Resolution #1142-09-09-2025: "approving a Moratorium on Data Mining Facilities until August 31, 2026, unless ended sooner by action of the Board of Supervisors").
• Current end date: —
• Sectors: cryptocurrency mining
• Moratorium ID: ia-jackson-county-2024
• Legal basis: Resolution #1066-09-17-2024 (initial); Resolution #1142-09-09-2025 (re-establishment). Both adopted by Supervisors Schwenker, Steines, Flagel. The Citizen Portal article on the March 17, 2025 [sic — likely March 17, 2026] zoning commission meeting recounted that "a previous moratorium on data-mining facilities enacted in September 2024 [was] later rescinded; several members of the public said the moratorium's intent…had not been fully satisfied before the applicant filed." This reporting confirms the rescission/lapse between June 30, 2025 and the September 9, 2025 re-establishment.
• What prompted it: Resolution text cites lack of current county ordinance and need to protect infrastructure, natural resources, and property rights through adequate setback provisions while the Planning and Zoning Commission gathers information and coordinates with multiple agencies.
• Affected projects: One Aurum Capital Ventures bitcoin/data-mining special-exception application (project sized at about 2.5 megawatts) was the subject of a unanimous March 17, 2026 zoning commission recommendation against the applicant (recommend keep parcel A-1 zoning, deny special exception); applicant John Holberic represented Aurum Capital Ventures.
• Detailed status: Active. The March 25, 2025 moratorium (Resolution #1105-03-25-2025) was never rescinded -- it expired naturally on 2025-08-31 per its own terms, per the recitals of the resolution that replaced it. It was re-enacted via Resolution #1142-09-09-2025, effective through 2026-08-31 unless ended sooner by Board action. As of 2026-07-31, no rescission or replacement ordinance has been confirmed in primary records; Planning & Zoning reportedly planned to present a proposed 12-month extension to the Board on 2026-07-28, but the meeting's minutes were not yet posted at research time and the outcome could not be confirmed.
• Outcome: County reserved right to terminate early upon adoption of an ordinance ("BE IT FURTHER RESOLVED that the Jackson County Board of Supervisors reserves the right to end the moratorium prior to the approved term…upon completion of a satisfactorily developed Data Mining Facilities Ordinance"). No final county ordinance had been adopted as of the captured March 17, 2026 zoning commission meeting.

• Current end date: —
• Sectors: data center

Jones County

• Type: County
• Status: ⚪ Replaced
• Date enacted: 2024-10-15 (signed October 15, 2024 BoS minutes record adoption of "Resolution Approving a Moratorium on Data Mining Facilities," numbered 2024-149, by 5-0 roll-call vote; same meeting also adopted Resolution 2024-150 imposing a parallel moratorium on Utility Scale Battery Energy Storage Systems on the same terms).

• Affected projects: Not specified in moratorium or ordinance text.
• Detailed status: Reclassified: initial temporary moratorium (Resolution 2024-149) expired and replaced by permanent regulatory ordinance (2025). Web verification indicates the county's approach was primarily regulatory, not a traditional moratorium.
• Outcome: County adopted comprehensive Cryptocurrency and Data Center Ordinance (2025) with special use permit requirements. Reclassified from moratorium to regulatory action after verification.
