Planning Commission advances new data center regulations for Louisville

The Louisville Metro Planning Commission has voted 5-3 to recommend significant amendments to the Land Development Code concerning data centers. These proposed regulations are now advancing to Metro’s planning and zoning committee for further review.

The new guidelines, drafted by Metro staff, aim to create distinct definitions for hyperscale, accessory, and telecommunications data centers. Key provisions include capping data center size at 500,000 square feet and restricting them to M-1 industrial zoning districts. Facilities larger than 50,000 square feet would require a conditional use permit, necessitating environmental, acoustical, and vibration studies, as well as a decommissioning plan. The amendments also mandate closed-loop water systems for cooling and set noise limits at 65 decibels, with emergency generators requiring a quarter-mile buffer from sensitive locations.

Planning Commission member Jim Mims emphasized the necessity of action, stating, "To do nothing at this point is not an option." He noted that the commission incorporated elements from a model ordinance provided by the Kentucky Resources Council, particularly regarding noise standards. Public concerns largely centered on air and noise pollution, excessive utility use, and proximity to residential areas.

Metro Councilman Andrew Owen indicated that the planning and zoning committee could begin reviewing the recommendations as early as September 15. If approved by the committee, the proposals will then go to the Metro Council for final consideration. The article notes that a six-month moratorium on data center applications, enacted last month, could conclude early if the Metro Council approves the new regulations before its scheduled expiration.
