Grant County

Grant County, South Dakota. Status: Adopted Ordinance.

Grant County's zoning ordinance has allowed a data processing center as a conditional use in the Agriculture District since Ordinance 2022-01B, published in December 2022, which requires a quarter-mile setback from homes, churches, and schools, noise limits at homes, and utility approval, but has no rules on water, emergency planning, or decommissioning. A proposed amendment, Ordinance 2026-01, would add water rules for larger data centers, including a water-use cap, meters, and yearly reports; it had a joint public hearing on August 10, 2026, and its second reading has been postponed more than once.
