Nassau Hit Pause on Data Centers. The Clock Is Already Running.
A temporary moratorium gives the county up to a year to write defensible rules for large data facilities. The decisions about water, electricity and land use are still ahead.
For unincorporated Nassau residents, the county has paused processing of covered data-center development applications while it studies possible rules. Future standards could affect where facilities go and how infrastructure impacts are handled; the county has not adopted those future standards.
On June 8, Nassau County commissioners approved Ordinance 2026-044, a temporary moratorium of up to 12 months on accepting, reviewing or approving specified development applications related to data centers, data processing, data mining and cryptocurrency mining. It applies to county development authority in unincorporated Nassau; it is not a Fernandina Beach city ordinance or a permanent countywide ban.
The quiet part of that decision is the rule-making window. The county says it wants time to examine water use, electric demand, land-use compatibility, environmental effects, infrastructure capacity and fiscal impacts, then consider changes to its comprehensive plan or development code if commissioners judge them necessary. Its staff fact-finding committee is tasked with research and public dialogue. The county explicitly says that committee does not make the final policy decision.
Florida’s 2026 data-center law, SB 484, took effect July 1. The county’s public explanation says the law preserves reasonable local regulation and adds a path for large-load electric tariffs and large-scale data-center water permits. These rules do not establish that Nassau has approved a project, that an existing resident’s power bill is rising because of one, or that any particular aquifer will be depleted.
The county posted June draft definitions and goals for public comment. Drafts are options, not adopted zoning standards. As of our October 13 review of the county’s data-center pages, the moratorium was the concrete action we could verify; we did not find a final policy package there. The public question now is what commissioners will adopt before the temporary pause ends.
What remains unanswered
- Has the county received or been approached about a specific data-center project, and what records can identify its site and utility needs?
- What final recommendations will the committee send commissioners, and when?
- What water, power, noise and setback standards will the county put into enforceable code?
