If the analysis identifies that proposed mechanical system operations could result in an exceedance of this noise performance standard, then specific measures to attenuate the noise impact shall be outlined in the analysis. The analysis shall be submitted to the City’s Building & Safety Division for review and approval prior to issuance of building permits. The final noise-reduction measures shall be included on all final construction and building documents and/or construction management plans and submitted for verification to the City. Specific measures may include, but are not limited to, the following measures or design features: • The project applicant shall utilize quieter mechanical systems that would not result in an exceedance of the City’s operational noise standards. • The project applicant shall enclose mechanical systems in a sound-attenuating structure or shall install sound barriers adjacent to the proposed system that would reduce operational noise levels to not exceed the City’s noise performance standards as measured at the property line.
