Summary

The bill gives counties and municipalities the power to adopt ordinances that control the size, height, design and number of data centers, and where they can be built. It also requires a public hearing and newspaper notice before any siting decision and adds water‑use and noise‑mitigation standards. Existing local rules that were in place before the law takes effect remain valid.
