Local votes and rules

🗳️ Public vote

Voters will decide a city charter change that would ban data centers that use more than 25 megawatts of power. City council refused the petition in August 2026, but the Ohio Supreme Court ordered the city to send it to voters. If it cannot be checked in time for November, a special election must be held.
