Data Center Rules Advance as EDOC Sets March 4 Follow-Up on “Community Benefits” Language
Committee boosts residential setbacks, tightens noise and compliance standards, and pauses development agreement debate pending legal review
Jefferson County’s Economic Development & Opportunity Committee continued its detailed review of proposed data center regulations this week, moving closer to a finalized draft while postponing a key decision on a potential community benefit agreement. The meeting focused heavily on tightening performance standards for setbacks, noise, water use, air quality, and enforcement, while also ensuring the ordinance remains legally defensible under recent U.S. Supreme Court rulings governing land-use exactions.
Early in the meeting, discussion turned to a 34-page draft community benefit agreement that had been circulated among members. County legal counsel cautioned that any required payments or concessions tied to zoning approval must meet strict constitutional standards, specifically demonstrating a clear connection and proportionality to project impacts. Because that section is still under legal review, the committee agreed to hold a separate meeting in early March to determine what form, if any, a development agreement requirement can take without creating legal risk for the county.
Much of the afternoon was spent walking line-by-line through the updated draft regulations. One of the most significant revisions increases the setback requirement for data center structures adjoining residential property to 500 feet. Non-residential adjacencies would require a 200-foot setback. Parking areas are permitted somewhat closer but must still maintain substantial buffers. Committee members indicated that the expanded residential setback directly responds to public concerns raised in prior meetings.
Noise restrictions were also clarified. Emergency generators must be enclosed within sound-attenuating structures and meet EPA Clean Air Act standards. The ordinance explicitly prohibits the use of generators for peak shaving, meaning operators cannot run backup power simply to reduce grid demand during high-cost periods. During discussion about cooling towers, members emphasized that the ordinance regulates decibel levels at the property line rather than specific equipment. In short, it does not matter whether the noise originates from generators, cooling systems, or any other source — if it exceeds the allowable limit at the boundary, it constitutes a violation.
Renewable energy standards remain intact in the draft. Data centers would be required to obtain 40 percent of their electricity from renewable sources at occupancy, increasing to 60 percent within five years. Renewable energy may be generated on site or obtained through qualified utility renewable programs. While some members questioned how renewable subscription programs function in practice, the committee left the language unchanged pending further review.
The draft also strengthens air and water protections. Operators would be required to submit air quality impact assessments addressing particulate matter, nitrogen oxides, sulfur dioxide, volatile organic compounds, and greenhouse gases. Semi-annual compliance reporting would be mandatory. Cooling systems must use closed-loop technology to limit water consumption, and once-through cooling systems are prohibited. Stormwater management systems would require semi-annual inspections by third-party professionals selected by the county, with costs borne by the developer. Several members expressed interest in making compliance reports publicly accessible to enhance transparency.
Enforcement provisions authorize civil penalties of up to $1,000 per day for non-compliance, which staff described as the maximum penalty the county can confidently defend under current law. Some residents questioned whether that amount would deter large corporations, but officials reiterated that penalties must remain legally sustainable. Decommissioning requirements also received attention. Rather than simply mandating demolition bonds, county leadership emphasized a preference for ensuring that facilities remain reusable at the end of their operational life. The goal, officials said, is to avoid leaving behind unusable industrial sites while preserving infrastructure that could attract future tenants.
During public comment, one resident praised the increased setbacks and sound mitigation provisions but encouraged the committee to further evaluate cooling tower impacts. Another resident voiced broader opposition to AI data centers, citing national concerns about environmental enforcement and generator operations. Committee members responded by noting that the draft regulations are designed to impose measurable, enforceable standards at the local level.
The committee concluded by scheduling a March 4 meeting to continue discussions specifically on the community benefit or development agreement component. Planning and Zoning is expected to review the regulatory framework in March, with County Council consideration to follow. While significant progress has been made on the technical aspects of the ordinance, the broader policy debate over economic development and community protections remains ongoing.
