Plain-English framing. Nassau County is the far northeast Florida county adjacent to Jacksonville, with Jaxport and St. Marys River frontage. The 12-month moratorium is a 'study moratorium' — it freezes new applications while the County does the research needed to update its comprehensive plan and zoning code. This is distinct from a 'permanent ban' (Monterey Park, below) and from a 'block-the-specific-project' lawsuit (Pine Island). What makes this a useful data point for the moratorium pattern. Nassau is a Florida county — Florida is broadly a Dillon's Rule state for counties on land-use matters but Home Rule for charter counties. Nassau County voted in 2008 to become a charter county, meaning its moratorium is on stronger legal ground than the Hood County, Texas moratorium that was rescinded last week. The Florida Constitution Article VIII Section 1(g) gives charter counties broad ordinance powers including moratoriums of reasonable duration. So this moratorium is meaningfully harder to attack than the Hood County / Texas pattern. What's covered. Ordinance 2026-044 covers 'data centers, data processing facilities, data mining or cryptocurrency mining operations' — broad enough to capture every relevant project type. It explicitly carves out 'in-process' applications, meaning developers with sites already in the queue are not affected. So the impact is on new entrants only, which means the moratorium constrains future inventory rather than killing existing pipeline.

Why it matters
Nassau County extends the moratorium tracker into Florida, which had been underrepresented vs. Texas, Virginia, and the Midwest. Two regulatory-graph updates: (1) The 'charter vs. non-charter Florida county' distinction is the equivalent of the Dillon's Rule vs. Home Rule distinction in other states — Cliff's per-state legal-authority page needs Florida split into the 20 charter counties and the 47 non-charter counties, because moratorium durability follows that line. (2) The inclusion of 'cryptocurrency mining operations' in the same ordinance language is the pattern most non-coastal counties will copy — the political coalition opposing data centers includes residents opposing crypto for separate reasons, and bundling the two raises the political ceiling on these ordinances. For the wiki, every county-level moratorium page should track whether crypto is bundled into the prohibition language.
