Draft ordinance limits noise to 55 dB at property lines, requires acoustical studies and annual monitoring for 10 years
The draft text requires that operational noise not exceed 55 decibels at property lines, includes octave‑band tonal limits, requires qualified acoustical engineers for compliance testing and mandates post‑occupancy and annual testing for a decade.
The full story
Residents asked specifically about noise and vibration from data centers. Planning staff read the proposed measurement standards into the record: "noise generated by the facility shall not exceed 55 decibels," and the ordinance includes octave‑band criteria for prominent tonal noise at specified frequencies. Staff acknowledged they are not acoustical engineers and proposed requiring applicants to hire qualified consultants to demonstrate compliance.
