Dakota County Judge Rules in Favor of Lakeville in Environmental Lawsuit Over Proposed Business Park Development
Published: May 26, 2026
LAKEVILLE, MINNESOTA: A Dakota County judge has ruled in favor of the City of Lakeville and Olam Holdings 1, LLC in a lawsuit challenging the city’s environmental review process for a major proposed industrial development that critics argued was likely tied to an alleged future hyperscale data center project.
The ruling stems from a lawsuit filed on August 5, 2025, by the Minnesota Center for Environmental Advocacy (MCEA) against the City of Lakeville and Olam Holdings 1, LLC. The lawsuit challenged the city’s approval of an Alternative Urban Areawide Review (AUAR) connected to proposed development within Lakeville’s business park. On May 26, 2026, Dakota County District Court Judge Bryce A.D. Ehrman granted summary judgment in favor of both defendants, dismissing the claims brought by MCEA.
The court also partially granted and partially denied MCEA’s request to supplement the administrative record with internal emails related to discussions about potential data center development. The judge allowed certain emails involving City of Lakeville officials to be added to the record, but denied the inclusion of additional communications between consultants and third parties.
At the center of the dispute was approximately 152 acres of land owned by Olam Holdings in Lakeville. The AUAR studied two potential development scenarios totaling roughly 1.36 million square feet of future industrial and office development. According to court filings, no specific tenant or end user had been identified during the review process.
The Minnesota Center for Environmental Advocacy argued throughout the case that the city’s environmental review intentionally obscured the possibility that the site could ultimately become a hyperscale data center campus. The lawsuit pointed to references in the AUAR involving high water usage, traffic modeling using data center land-use codes, and references to computer and ventilation systems as evidence that the city anticipated data center development. MCEA argued the city should have conducted a more extensive environmental review under procedures applicable to “large specific projects” under Minnesota environmental law. The group alleged the AUAR inadequately analyzed potential impacts on groundwater resources, electrical infrastructure, air quality, greenhouse gas emissions, light pollution, and noise.
However, Judge Ehrman ruled that the city properly used the AUAR process to study general development scenarios rather than a defined project.
In the court’s memorandum, Ehrman concluded there was no sufficiently specific project proposal in existence that would trigger the additional review requirements cited by plaintiffs.
“The only proposal is to develop the area into light industrial or office park uses,” the judge wrote, concluding that the proposal lacked the specificity required to qualify as a “project” under Minnesota environmental review law.
The court further stated that the city appropriately evaluated multiple possible development scenarios because no end user had been identified at the time of review. According to the ruling, potential future uses considered included “data center, manufacturing, warehouse, and office space.”
Judge Ehrman also rejected claims that the city’s approval of the AUAR was arbitrary or unsupported by evidence.
The memorandum stated that the city relied on accepted environmental review methodologies, including greenhouse gas calculators endorsed by the Minnesota Pollution Control Agency and the Minnesota Environmental Quality Board.
The judge acknowledged plaintiffs’ concerns regarding water use and potential noise impacts from data centers, but noted that no actual data center project had been formally proposed. The court found the AUAR appropriately addressed possible industrial impacts at the planning stage while recognizing that future projects could still require separate environmental review or permitting if thresholds are exceeded.
Regarding the city’s mitigation plan, the court ruled that because the AUAR functions as a planning tool rather than approval of a specific project, the city’s commitments to future permitting, regulatory compliance, and additional studies as needed were appropriate at this stage.
“The City took a hard look at the possible problems involved in their anticipated development and engaged in reasoned decision-making when it approved the AUAR,” Ehrman wrote in the ruling.
Following the ruling, the City of Lakeville issued a statement welcoming the decision.
“We are pleased with the Court’s decision and the outcome of this case,” Lakeville Mayor Luke Hellier said in a statement released Tuesday. “The City was confident in the process we followed, and this decision affirms the careful review and reasoned decision-making that took place. Lakeville remains open for business, and this area of our business park continues to be an important opportunity for thoughtful economic development.”
The city also noted that future projects proposed for the area will continue to undergo standard development review and permitting processes as they are brought forward.
Broader Legal Battle Over Proposed Minnesota Data Centers Continues
Additionally, the lawsuit against the City of Lakeville was one of several environmental lawsuits filed by the Minnesota Center for Environmental Advocacy involving proposed large-scale data center developments across Minnesota.
According to a legal update published by MCEA on May 15, 2026, the organization stated it currently has multiple lawsuits challenging AUAR environmental review processes tied to proposed hyperscale data centers in communities including Lakeville, Pine Island, Hermantown, Monticello, and Faribault. MCEA argued in those cases that cities improperly used AUAR reviews for projects they allegedly knew were likely to become hyperscale data centers without specifically identifying them as such. The organization claimed those environmental reviews failed to adequately study issues including water use, greenhouse gas emissions, energy demand, light pollution, noise impacts, and mitigation measures.
In its May 2026 update, MCEA specifically stated that internal city communications in the Lakeville case showed the proposed 1.3 million-square-foot “light industrial” project was intended to be a data center. The organization also noted that both sides had asked the court to rule on the merits through summary judgment rather than proceed to trial.
MCEA further stated in the update that the proposed Lakeville project, associated with a company called TeraWatt, had not advanced to the permitting stage and “may be inactive.”
The organization outlined similar ongoing legal disputes in Pine Island, Hermantown, Monticello, and Faribault involving proposed hyperscale data center developments and environmental review procedures. In some of those projects, companies, including Google, were later publicly identified as potential developers behind proposed data center campuses.
MCEA also noted that filing environmental lawsuits alone does not automatically stop construction or permitting activity. The organization explained that courts must separately issue injunctions to halt development activity while litigation is ongoing.
