Noise, acoustical studies and generator testing limits highlighted in draft ordinance

Noise mitigation and verification were recurring themes in the Aug. 5 meeting. The draft ordinance references Minnesota Pollution Control Agency standards and would require a third-party acoustical study as part of any permit application, with post-construction testing to confirm compliance. Attorney Mattick explained the ordinance references MPCA rules to avoid conflict with statewide standards while giving the City authority to require an independent study and to order annual third-party noise testing if needed.

Members discussed mitigation options — building construction techniques, berms, vegetation, fencing and noise-dampening materials — and emphasized the ordinance should allow flexibility so required measures match the site conditions. The draft also sets generator testing limits at 100 hours per generator per calendar year and notes generator operation may be subject to state and federal environmental regulations.
