Enforced by
Fairfield City Council

The Fairfield City Council PASSED AN ORDINANCE establishing a PAUSE ON ANY DEVELOPMENT of a data center within the city. The instrument is an ORDINANCE rather than a resolution, which matters more than it might appear — several measures in this dataset are resolutions directing staff not to process applications, and a resolution is a weaker footing than an enacted ordinance if a developer chooses to test it. Fairfield sits in Jefferson County, and this dataset already indexes a Jefferson County ordinance regulating data centers, so the city and its county have each acted. That combination closes the jurisdictional patchwork that has defeated measures elsewhere, where a project turned away at a city line simply relocated into unincorporated territory. Iowa has a substantial cluster: Waterloo adopted a three-month moratorium, Marshalltown a four-month one, Lee County and Adair County have acted, and Peosta is considering an extension of an existing pause.

Legal detail

Fairfield, Iowa (Jefferson County) — ORDINANCE establishing a PAUSE ON ANY DEVELOPMENT of a data center within the city, passed by the City Council. INSTRUMENT: an ORDINANCE, which is the stronger form. Several measures in this dataset are RESOLUTIONS directing that applications not be accepted or processed — Gregg Township PA data center moratorium resolution (2026), Loveland CO 12-month data center moratorium (2026), Portland OR data center NDA resolution (2026) (which merely URGES) — and each carries a flag that a resolution is a weaker footing than an enacted ordinance if tested by a developer. Fairfield's is an ordinance. SCOPE IS BROAD ON ITS FACE: 'a pause on ANY DEVELOPMENT of a data center', which reaches development rather than only applications or permits, though the precise operative verbs are not given. CITY-COUNTY PAIRING: Jefferson County IA data center ordinance + 12-month moratorium is ALREADY INDEXED as the surrounding county's ordinance regulating data centers, so BOTH THE CITY AND ITS COUNTY HAVE ACTED. That closes the jurisdictional patchwork that defeated the Athens measure (a municipal pause that could not reach a site outside the city limits) and that Newport NC data center moratorium (2026) addressed by extending across its extraterritorial jurisdiction. The same city-county convergence is recorded at Leesburg GA six-month data center moratorium (2026) and Lee County GA Data Center Moratorium. IOWA CLUSTER: Waterloo IA 3-month data center moratorium (three months), Marshalltown IA 4-month data center moratorium (four months), Lee County IA 1-year data center moratorium, Jefferson County IA data center ordinance + 12-month moratorium, Adair County IA data center permit fee (2026) ($500 permit fee); Peosta is deferred as considering an extension of an existing moratorium that is itself unindexed. NOT ESTABLISHED: the term length (none reported — expires_date NULL), the vote, the exact date, the ordinance number, and any threshold.
