Noise and Vibration (cont.)

Increases in ambient noise levels from onsite wind energy generation.

DSP, DSP-V, CPP, &

CPP-V scenarios

4.J-3b: Small wind turbines shall be sited a minimum of 50 feet from the property line of noise sensitive land uses (e.g., residential, schools, religious institutions). Utility scale wind turbines shall be sited a minimum of 100 feet from the property line of noise sensitive land uses and separated from one another by a distance no less than a minimum of two times the rotor diameter of the larger turbine.

Applicants for development of wind turbines

Community Development Director

The Community Development Department shall review proposed site- specific development plans prior to public hearings or prior to approval if no hearing is required.

Approval of wind turbine development in compliance with Mitigation Measure 4.J- 3b.

Construction noise.

DSP, DSP-V, CPP, &

CPP-V scenarios

4.J-4a: All applicants for site-specific development within the Project Site shall implement site-specific noise attenuation measures during all construction- related activities under the supervision of a qualified acoustical consultant as a pre-requisite to issuance of site grading(s). These measures shall be included in a Noise Control Plan that shall be submitted for review and approval by the City of Brisbane Building Department to ensure that construction noise does not exceed the standards set forth in the City’s Noise Ordinance. These attenuation measures shall include all or any combination of the following control strategies:

• Limit standard construction activities to between 7:00 a.m. and 7:00 p.m. Monday through Friday and between 9:00 a.m. and 7:00 p.m. on weekends and holidays. Pile driving and/or other extreme noise- generating activities (greater than 90 dBA) would be limited to between 8:00 a.m. and 4:00 p.m. Monday through Friday, with no extreme noise-generating activity permitted between 12:30 p.m. and 1:30 p.m. No extreme noise-generating activities would be allowed on weekends and holidays;
• Equipment and trucks used for construction shall use the best available noise control techniques (e.g., improved mufflers, equipment redesign, use of intake silencers, ducts, engine enclosures, and acoustically attenuating shields or shrouds;
• Impact tools (e.g., jack hammers, pavement breakers, and rock drills) used for construction shall be hydraulically or electrically powered wherever possible to avoid noise associated with compressed
