Local votes and rules
🗳️ Public vote
Voters will decide four referendums that could strike down zoning ordinances the city passed for the planned Amazon Web Services data center. A separate citizen zoning ordinance was kept off the ballot by the county elections board, and its backers went to the Ohio Supreme Court.
🗺️ Zoning change
City council passed emergency rezoning that clears the way for a 1.9-million-square-foot Amazon Web Services data center on 471 acres along South U.S. 68. Emergency laws take effect right away and cannot be put to a referendum.
⚖️ Court case
A resident sued to overturn the 'emergency' rezoning for the Amazon data center, saying the emergency label was used to block a public vote.
✋ Turned down
City council re-passed the generator noise rule 6-1 as an emergency, but the rezoning for the Amazon Web Services data center failed because it needed at least 75% of the vote.
⚖️ Court case
A federal judge ruled that Wilmington did not give proper public notice before passing zoning, data center use and generator noise rules for a planned $4 billion Amazon Web Services data center. The city had to redo them before acting on the site plan.
