Missoula County adopts yearlong pause on new data-center development
Missoula County commissioners have adopted an interim countywide moratorium on new data-center development, creating a roughly one-year pause on new projects while questions about water use, energy demand and community impacts remain central to the policy debate.
The commissioners voted on the interim zoning measure July 9, 2026. Reports describing the action say the moratorium is in effect through July 8, 2027.
The measure applies countywide and concerns new data-center development. It should not be read as a prohibition on all data-center activity or as a finding about existing facilities.
What the interim restrictions change
The action places new data-center proposals under an interim countywide restriction rather than allowing them to proceed under the prior approach during the moratorium period. The available reports characterize the action as a pause, not a permanent decision on data centers in Missoula County.
The one-year timeframe gives the policy question a defined end date: July 8, 2027. The reports available for this account do not describe the resolution’s precise exemptions or other operational details, so the scope beyond new data-center development is not established here.
Water use, energy demand and potential community impacts were identified as issues in the debate surrounding the county’s action. Those issues are now directly tied to county land-use policy for a type of industrial development that can raise significant local planning questions.
Bonner Mill proposal part of debate
A proposed data center at the former Bonner Mill site was part of the controversy surrounding the countywide measure. The moratorium therefore has direct relevance for that proposed industrial development as well as any other new data-center proposal covered by the countywide restrictions.
However, the available reports do not establish the final status of the Bonner Mill application. The countywide moratorium also does not, by itself, permanently reject that proposal.
What happens next
The known deadline is July 8, 2027, when the reported interim moratorium is set to end. Until then, the county’s action makes water, power demand and community considerations central topics in decisions about new data-center development.
Whether the county changes, extends or replaces the interim restrictions before that date is not established by the available reports.
