Update 6/12/2026:

Missoula County planning staff have reviewed another application from Krambu and deemed it insufficient. The latest application and letter from the County are available under the Documents tab to the right. Krambu will need to submit a complete application before a hearing with the Missoula Consolidated Land Use Board can be scheduled.

The Bonner Data Center project developer is continuing to finalize materials for presentation to the Missoula County Consolidated Land Use Board (MCCLUB). At this time, the public hearing schedule is to be determined, pending receipt of a complete application.

You can sign up to follow this project at the right-hand side on this page. When the new date is determined for the MCCLUB public hearing, project followers and commenters will receive an email.

This project will be reviewed by the Missoula County Consolidated Land Use Board (MCCLUB). This land use board holds their public hearing meetings on the first Wednesday of the month at 6 p.m. in the Sophie Moiese room of the Missoula County Courthouse. There may occasionally be a second meeting in the month, which will usually be the third Wednesday. There will be prior notice. These meetings are always open to the public.

The meeting agenda and related documents will be published on the Consolidated Land Use Board page




Project Overview

Missoula County is reviewing a proposed data center at 9314 Bonner Miller Road as a Special Exception described in Section 11.6.D. of the Missoula County Zoning Regulations. The property is zoned for heavy industrial use.

The proposal involves reusing a portion of the former mill building — commonly referred to as the planer building — for a high-performance computing (HPC) data center. This means most of the development would occur inside the existing structure, with no major expansion of the building footprint. Interior improvements would include constructing specialized rooms to house computer servers and supporting equipment.

The proposed data center would operate continuously, 24 hours a day, seven days per week, with minimal on-site staffing and relatively limited vehicle traffic associated primarily with maintenance and service visits.

The initial phase of the facility is expected to use approximately 7 megawatts (MW) of electrical power, with the potential to expand over time to utilize up to 29 MW, which is the estimated capacity currently available at the site.

What is being reviewed in this project proposal?

The Special Exception review is required when the use, because of location, scale, required infrastructure or other potential impacts, requires a special degree of consideration and control to ensure such uses are consistent and compatible with the overall community character and whether potential impacts can be avoided or mitigated.

This page has been updated to reflect revised staff analysis of the scope of review. The Missoula County Consolidated Land Use Board (MCCLUB) must not approve a special exception unless and until they find the project application demonstrates all of the following:

  1. The proposed use or development will be compatible with and will not substantially injure the value of adjoining property.

  1. The proposed use preserves the character of the district, and the property is suitable for the proposed use (e.g. can meet the bulk and dimensional standards without requiring a variance).

  1. The proposed use promotes the purpose and intent of the TIF Special District, where appropriate.

  1. Substitute or additional design standards will preserve and protect the area’s architectural and aesthetic qualities.

  1. In reviewing a Special Exception application MCCLUB shall give due consideration to the following:

a) Access, traffic, parking demand, non-motorized transportation and onsite vehicle circulation

b) Dedication and development of streets, rights of way, and public use areas, such as adjoining sidewalks

c) Impacts on or of public and private utilities or services

d) Proposed siting of any new structures necessary to accommodate the use and their relationship to adjoining and surrounding properties

e) Recreation opportunities and open lands available to serve the use

f) Natural resource protections

g) Landscaping and screening requirements

h) Signage and street lighting

i) Noise, vibration, outdoor lighting and other on and offsite impacts from the use

j) Frequency of use and hours of operation

k) Area of land necessary and adequacy of the site to accommodate the use and meet the intent of the district and character of the neighborhood

l) How the proposed use addresses the purpose of the TIF Special District intended to attract, retain, grow and develop secondary value-adding industries

m) Any other unique or relevant circumstances related to the property.

The burden to demonstrate compliance with these criteria falls to the applicant, not the County or MCCLUB.

Reasonable and appropriate conditions may be required to ensure that any potentially injurious effect of the Special Exception on adjoining properties, the character of the neighborhood, the purpose and intent of the TIF Special District, or the health, safety and general welfare of the community will be minimized. Conditions much be based on the criteria for review.

Zoning compliance permit

If a special exception is approved, the developers must apply for a zoning compliance permit. The permit application must demonstrate compliance with the County's data center zoning regulations, including requirements for new renewable energy and e-waste recycling. Zoning compliance permits are subject to administrative review and do not go through public hearing process.

I STRONGLY oppose this data center and all data centers anywhere in this state or on this planet. When will humans learn to stop destroying things for short term financial gains for a few people? It is way past time to wake up. We cannot live without water, and this data center threatens the water for our community. Should be an easy NO.

ahronek 15 days ago

This is probably the single dumbest idea I've heard about. Weather or not you like it; nature tourism is the lifeblood of the Montana economy. A data center is entirely antithetical to wildlife and nature conservation, why on earth would we shoot ourselves in the foot for the sake of some AI chatbot?

Missfit 15 days ago

I oppose the proposed data center near Bonner because it is incompatible with the natural character and environmental values of the Blackfoot Valley and Montana.

The Bonner area serves as a gateway to one of Montana's most scenic landscapes. A large industrial facility with extensive cooling infrastructure, security lighting, fencing, backup generators, and utility development would permanently alter the area's rural character and diminish the natural beauty that residents and visitors value.

The project also raises concerns for wildlife and fisheries. Increased noise, lighting, traffic, and human activity have the potential to disrupt wildlife movement and habitat use in an area that supports a wide variety of native species. The Blackfoot River corridor is particularly important as both wildlife habitat and a recreational resource.

Most concerning is the potential impact on the Blackfoot River and its world-class trout fishery. Native trout depend on cold, clean water. If cooling water is withdrawn from the river and returned at higher temperatures, it could contribute to warming of the river, particularly during summer periods when water temperatures are already stressful for fish. Any increase in water temperature or degradation of water quality could negatively affect native trout populations and the recreational economy that depends on them.

The Blackfoot River, its fisheries, wildlife, and scenic values are irreplaceable public resources. These resources should be protected, and I urge decision-makers to deny this proposal unless it can be demonstrated that there will be no significant impacts to the river, wildlife, or the character of the Blackfoot Valley.

It is my opinion that this data center will bring nothing positive to Bonner or Montana.

I strongly oppose this (and any future) data centers at this site and the surrounding area. There are essentially no local benefits to these data centers--it's just a question of which communities they can bully into shouldering the burden. This data center is just the beginning of a slippery slope to ruining the things that make Missoula County a place worth living and visiting.

Put this data center in California, it would fit right in. NO DATA CENTERS SHOULD BE ALLOWED IN MONTANA.

This proposed data center would have significant and lasting impacts on Montana, its communities, and the natural landscapes that make this state so special. Allowing it to be built feels contrary to the values that Montanans have worked hard to protect for generations: our open spaces, clean environment, abundant wildlife, and way of life.
The environmental consequences will be far-reaching, affecting wildlife habitats, increasing energy and water demands, contributing to rising temperatures, and impacting snowpack and the ecosystems that depend on it. These are not just environmental concerns; they are concerns about the future of our communities, our outdoor heritage, and the resources that sustain us.
Montana’s beauty and natural character are among its greatest treasures. Once they are compromised, they cannot easily be restored. It is deeply concerning that decisions with such profound local impacts may primarily benefit out-of-state corporations and investors, while the people who live here are left to bear the environmental and community costs. We have a responsibility to protect this place for future generations and ensure that short-term economic interests do not come at the expense of Montana’s long-term health, identity, and future. So please do not allow this data center to be built. No data centers should be allowed in the state of Montana.

I ask respectfully, what reason do we have for allowing this? It will create job (that’s not a typo — we’re likely looking at one singular job for the community, if that). Meanwhile, the impact on our community’s water will be irreversible. This means not just impacts on our ability to maintain a healthy ecosystem that provides enough water for its human residents to survive and thrive, but also unpredictable (at best) outlooks for threatened species such as the Bull Trout, which our state has been fighting like hell to protect.

If my seven year old can’t fish in the early hours of the morning so as to protect the trout population, then why would we possibly allow a massive, water-consuming data center that offers literally no benefits to our community to suck up our most vital natural resource and raise the temperatures of the remaining water past the point of species viability?

At least my kid would eat the fish.

Rick Hall, chair of the Bonner-Milltown community council, was quoted in the Pulp speaking about the data center proposal saying, “I think we ought to ask, is a bigger casino good for our community?Probably not. But that is not the yardstick for whether a business is there or not. And you know, in this country, it’s whether businesses choose to be there so they can make money. That’s it. Not to be good to the community.” While I understand the analogy Rick is attempting to make, respectfully, this is inaccurate. There are many businesses that could be argued they are not “good” for a community. Examples may include bars, dispensaries, and yes, casinos. However, the difference between these businesses and an AI data center are extensive. For example, People may largely avoid the potential negative effects of a casino by choosing not to enter the establishment. They can choose not to gamble. Similarly to how people can choose not to consume alcohol or other substances, if they so choose. An AI data center does NOT allow nearby residents to choose whether or not they will be affected by it. The water, light, noise, and environmental pollution will affect us (Bonner residents, like myself). We cannot choose to not partake in the effects of a data center in our neighborhood, should it be built. I live across the street from the site. Please consider that allowing this business to proceed means taking away the agency of local residents to live a safe, healthy, peaceful, and environmentally sound existence in our own community. This would infringe upon our rights as citizens. So, no, it’s not like a casino, Mr. Hall. Please consider how you would feel if you lived across the street from the site and knew your own health and safety were being compromised — without your consent. Keep us safe. Thank you.

NO DATA CENTER! We as humans have the capacity to create so many amazing things using our own creativity. We have the power to create something much better than data centers. The direction capitalism is taking us is straight into the ground. Our earth cannot sustain this continued action… or rather, it will not sustain us. We are destroying our only home for the sake of technological advancement that quite frankly, most do not even want. MATRIARCHY NOW!! MATRIARCHY NOW!! Death to the patriarchy, its greed, and the harm we continued to do to our earth and one another.

I’m my opinion adding a data center to any part of Montana would go against every fiber of what makes Montana what it is. With our wide open fields of grass, canola, forests and countless other species of plants that would be affected by a data center. You also got to look at the disturbance of the water near any area we would be putting any data centers. These data centers will start by taking more water from those areas than we can afford, most the state is always considered in drought season and with the lessening of snowfall throughout the years we don’t have water in excess anyways. Adding data centers will also impact native fish species and their natural spawning areas that these fish rely on to survive. As I conclude this I have one more thing to say. Why don’t you go door to door as someone wanting this data center to be built and ask some of the locals what they think of the idea, I bet that those true Montanas, the ones not selling out their land for money, would oppose the idea of a data center.

DravenMastel 18 days ago

It would be shameful to allow a data center at this site. A data center will provide zero new jobs while negatively impacting the surrounding community. It will use a staggering account of water and electricity, and ratepayers will see our utility bills rise as a direct result. It will create an annoying noise, like an air conditioner running 24/7, that nearby residents will be unable to escape. It will negatively impact wildlife and deplete water resources. I can't think of one single benefit this data center can offer our community. This site has so much potential to attract industry that would create jobs and benefit the surrounding community, and we lose all of that economic potential by allowing a data center to fill it with machines instead of people. And a data center will hurt surrounding businesses - the noise alone will negatively impact the ampitheater, because the data center's hum will be 24/7. I don't see all these issues being addressed, and I doubt that it is even possible for a data center to exist without serious environmental harm, pollution, damage to water resources, utility hikes to ratepayers, and a constant noise that drives people batty and lowers nearby property values, all while bringing zero full-time jobs to Bonner. Simply look at every other data center that already exists for a blueprint of the damage that will come to our community if a data center is allowed in here.

A data center would poison our rivers, raise energy costs that are already too high, and do untold damage to our area. It should be stopped at all costs.

Hello members, it is a general consensus that most people don’t want the AI centers. The way it is designed and impacts people’s lives and our environment is devastating, the proof is in other established AI center areas. Water has been a topic for many conversations about drought and our water tables shrinking rapidly. AI centers in other states have shown proof of draining water and power from people making it unaffordable or not accessible. If the water goes people die. If our plants and animals go people will die. This is so much bigger than money for technology that is new and damaging. Don’t allow it in push the creators to do better if they want it to exist. Montana gold is the water.

Hello Members. I strongly oppose the Bonner Data Center. I have friends that live directly across the proposed project and they have informed me of major issues. The top issue being environmental issues that will hurt our local rivers. We worked so hard to get the Clark Fork and Blackfoot rivers back to their natural flowing state. Why would risk endangering these special rivers and species that inhabit them, again? Also, it seems this project would not supply many jobs for the community once it’s up and running. It’s clear this project is not in our community’s best interest.

Jarek 18 days ago

I am writing to express significant concern and fear regarding the negative impacts of the proposed data center in bonner. I am begging you to reject the proposal so that we can preserve our water and community. We will commit our selves to ruin and death if the data center is allowed. Please. I do not want my daughter to live in a place where we can't drink or use the water and where the wild life has been lost and the river run dry. I am a 4th generation montanan and do not want to have to leave for safety reasons.

As someone who attended the first meeting and witnessed Steven Wood (Krambu CEO) dodge questions and change information he'd already given- this company does NOT care about anything but lining their pockets. No care for the environment, nor the people here. My child goes to school 100 feet away from where they want to operate this data center, yet they got annoyed with questions about noise, safety, clean water, and electricity. Please, keep our state local. Don't sell it out any further. Do your research, educate yourself on Krambu, and AI in general.

NO DATA CENTER IN BONNER!!!

alyssaj 18 days ago

I wanted to share my input that I also strongly oppose the proposed data center being allowed to construct in Bonner.
The concerns I have are how it will affect the surrounding areas, the water quality, energy usage and cost, and the residents of the area.
How are they going to address those concerns? How can they prove - beyond doubt - that our concerns are invalid?
I do not care how much money is promised because the data centers that have popped up elsewhere have harmed the communities that surround them with lower quality water, light pollution, and makes acres of land unusable.
They are planning to have minimal staffing at this center while taking up our water, electric, and land resources. While they may bring in temporary jobs during the center's construction (if they do not outsource the work to out-of-state construction companies), they are not bringing us much benefits -- only noise, pollution, and needless headaches.
Please do not support the data center in Bonner.

Please, for the love of all that is natural, good, healthy, and beautiful, do NOT allow this atrocity in our community. It will undoubtedly destroy our local ecosystems and our own health and wellness with it. The rich and privileged may not notice, but the majority of us will suffer.

Camille 19 days ago

I strongly oppose this data center and all AI data centers. We don’t need AI. We need clean water and air. We need to maintain the fish populations that are already endangered and protected in the Blackfoot. No good will come from this center being placed anywhere in Montana.
