Nassau County Opens Comment Period on Data Center Regulations

Nassau County has opened a public comment period on proposed data center regulations, giving residents until Jan. 8 to review and respond to a draft report that could shape how—and where—large-scale technology infrastructure takes root in one of Florida's fastest-growing counties.

The Nassau County Board of County Commissioners is reviewing an initial draft report and findings from the Nassau County Fact-Finding Committee on Data Center Development. The report examines data center operations, infrastructure demands, environmental considerations, and potential community impacts, and includes recommendations and draft regulations for the commission's consideration. An online portal at nassaucountyfl. com/1528/Data-Centers is open for residents to review the report and submit comments through Jan. 8, 2027, at 11:59 p. m. All submitted comments will be read and provided to the Board of County Commissioners.

What's happening

The Nassau County Board of County Commissioners convened a fact-finding committee to study data center development and draft potential regulations. The committee's initial report is now available for public review and comment.

Residents who cannot attend in-person meetings can submit written comments through the county's online portal. The comment period closes Jan. 8, 2027, at 11:59 p. m.

A public workshop is scheduled for Monday, Nov. 9, from 3 to 5 p. m. in the Board of County Commissioners chambers in Yulee. The workshop will allow residents to participate and provide feedback in person.

Formal public hearings are scheduled for Dec. 1, Dec. 14, and Jan. 25, 2027, as the county considers potential changes to its Land Development Regulations. The fact-finding committee's report is intended to inform the Board of County Commissioners' consideration of potential policy options; the report and its recommendations are not adopted policy.

Why data centers matter to Nassau County

Data centers—facilities that house the servers, storage, and networking equipment that power internet services, cloud computing, and artificial intelligence—are among the most infrastructure-intensive land uses a community can add. Projects of this type typically demand utility-scale electrical service measured in tens to hundreds of megawatts, comparable to the load of a small city, along with substantial water consumption if evaporative cooling systems are used.

For Nassau County, which is experiencing rapid residential growth driven by the Wildlight master-planned community near Yulee and development along the A1A and SR 200 corridors, the arrival of data center proposals raises questions about capacity and priority. The county's electrical service is provided by Florida Power & Light, and water and sewer systems vary by provider across the county; large industrial users would require service agreements and, in some cases, dedicated infrastructure extensions.

Data centers also present a unique economic trade-off. They generate substantial property-tax revenue relative to their footprint but create relatively few permanent jobs—typically a small number of technicians and maintenance staff. Construction employment can be significant during the build phase, but the operational profile is lean compared to manufacturing or logistics uses that occupy similar-sized parcels.

The environmental dimension centers on energy sourcing, cooling-water discharge if surface-water systems are used, stormwater management from large impervious surfaces, and compatibility with Nassau County's rural and suburban character. The county's eastern edge abuts the Intracoastal Waterway and is within the airshed and watershed of the Timucuan Ecological & Historic Preserve and the Guana Tolomato Matanzas Research Reserve, both sensitive coastal systems.

How new regulations could shape development

The fact-finding committee's recommendations, once finalized and adopted by the Board of County Commissioners, would become part of Nassau County's Land Development Regulations—the code that governs where different types of development can occur, under what conditions, and with what design and performance standards.

Regulations for data centers typically address setbacks from residential areas, noise limits (cooling equipment can generate continuous sound at the property line), screening and landscaping requirements, utility capacity demonstrations, and sometimes performance bonds or impact fees to offset infrastructure costs. Some Florida counties have also imposed special-use permit requirements that give boards discretionary review authority over siting and design.

The timing of Nassau County's review is notable. The county's regulations would be among the first in Northeast Florida to explicitly address data centers as a distinct land use. As the region competes for technology investment—Jacksonville has attracted data center interest in areas near JEA's large substations, and other Southeastern states have pursued the sector aggressively—Nassau's rules could either encourage projects by offering clarity or steer them elsewhere by imposing constraints that developers find burdensome.

For residents, the practical effect of the regulations will be felt in two ways: whether data centers can be built near existing neighborhoods, and what performance standards—on noise, traffic, lighting, stormwater, and aesthetics—would apply if they are approved. These are the questions the public comment period is designed to surface.

Infrastructure and fiscal questions

One of the central considerations in the fact-finding report is infrastructure demand. Data centers are electrically intensive but require relatively little else in the way of traditional infrastructure: they generate minimal vehicle traffic after construction, do not require large workforce housing, and add negligible load to schools or parks.

However, the electrical load is material. A single large data center can require as much power as several thousand homes. In a county where residential growth is already driving substation upgrades and distribution-line extensions, adding industrial-scale electric users raises the question of who pays for capacity enhancements and whether utility planning can accommodate both residential and data center growth without service-reliability trade-offs.

Water use is another variable. Some data centers use air cooling, which requires minimal water; others use evaporative cooling, which can consume hundreds of thousands to millions of gallons per day depending on the facility's size. If a proposed data center relies on evaporative cooling, it would need a consumptive-use permit from the St. Johns River Water Management District, the state agency that regulates water withdrawals in Northeast Florida. Public water systems would need to confirm they have the capacity, or developers would need to drill private wells—an option that raises questions about aquifer draw-down in areas where private residential wells are common.

On the fiscal side, data centers can add significantly to the property-tax base. The equipment inside a data center—servers, cooling systems, backup generators—is classified as tangible personal property and is taxable in Florida. A large facility can represent hundreds of millions of dollars in assessed value, generating recurring revenue for the county, school district, and other taxing authorities. Against that revenue, the county must weigh the cost of any public infrastructure investments, the opportunity cost of the land (what else might have been built there), and the less quantifiable impact on community character.

What happens next

The public comment period runs through Jan. 8, 2027, at 11:59 p. m. Residents can submit comments through the county's online portal at nassaucountyfl. com/1528/Data-Centers.

The next public workshop is scheduled for Nov. 9, from 3 to 5 p. m., in the Board of County Commissioners chambers in Yulee. The workshop format typically allows for presentations, question-and-answer sessions, and public input.

Formal public hearings—where the Board of County Commissioners would consider specific amendments to the Land Development Regulations—are scheduled for Dec. 1, Dec. 14, and Jan. 25, 2027. State law requires public notice and at least two hearings for changes to land development regulations. Residents who wish to speak at the hearings can sign up in person or, depending on the county's procedures, in advance.

All comments submitted online will be provided to the Board of County Commissioners for review before the hearings. The commission will have the authority to adopt the fact-finding committee's recommendations as drafted, modify them, or decline to adopt new regulations.

Nassau County's deliberation on data center regulations is unfolding as Northeast Florida contends with a broader question: how to channel growth toward uses that align with community priorities and fiscal sustainability. The outcome in Nassau—a county that has carefully guarded its small-town identity while absorbing thousands of new residents—will test whether local governments can craft rules nimble enough to attract investment without surrendering the prerogative to say no when a project doesn't fit. The January deadline ensures that residents, not just industry, have a seat at the table as those rules take shape.
