Summary
Anchorage's zoning code makes data centers prove their noise stays within citywide property-line sound limits before a conditional use permit is granted.
Completion of a noise mitigation study for projected operational noise levels, including at peak operation, demonstrating that the operation of the data center will not exceed the standards stated in AMC Section 15.70.080A.
(A) The study must include consideration of sound source location and directivity, and barrier effects of buildings and topography, for all proposed development on a lot or site plan.
(B) If the development will be completed in phases, the study must address both the proposed phase and the ultimate buildout of the proposed development.
ii. If the facility requires connecting to and drawing power from the surrounding electrical grid, the application must include a written statement from the electrical utility or utilities demonstrating that there is sufficient system capacity to meet the facility's projected demand at peak operation. The project application shall document estimated electrical demand at both normal and peak operations.

Full Breakdown
Under AMC 21.05.060(A)(2), a data center applying for a conditional use permit must submit a noise mitigation study covering projected operational noise at both normal and peak load, showing the facility will not exceed the property-line limits in AMC 15.70.080A: as low as 60 dBA at a residential boundary in daytime and 50 dBA at night for residential-emitting sources, rising to 70-80 dBA for industrial-zoned sources. Cooling, ventilation, and generator equipment must be fully enclosed unless the planning director finds enclosure mechanically infeasible. A data center next to a residential use or noise-sensitive zone must also sit at least 200 feet away, a setback only small data centers can get waived.
Violations & Fines
A deficient or missing noise study can sink the conditional use permit application; noise that exceeds AMC 15.70.080A limits once operating can draw enforcement orders and fines under Chapter 15.70.
