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.


Project summary

Current step: Missoula County has requested more information

Application status: Fifth application submitted; Missoula County has requested more information.

Expected hearing: Postponed until further notice

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.

    The site is zoned Industrial Center, Heavy. A data center would be an allowed use on the property. However, Missoula County has additional zoning regulations that apply to data centers and cryptocurrency operations throughout the county. These regulations include:

    • All power for the operation must come from a new renewable energy source (meaning it has not been on the market yet)

    • The operation must recycle all electronic waste

    • Because it is located within 500 feet of a residential area, the proposal must go through a special exception review to ensure impacts to nearby properties are addressed, including traffic, noise, lighting, landscaping, and screening and buffering
