Project Environmental Protection Action 1 – Construction Noise As a standard condition of development approval, the City requires the implementation of measures for the control of construction-generated noise levels. Commonly applied measures in Santa Rosa include limiting noise-generating construction activities to the less noise-sensitive hours of the day, prohibiting idling of heavy-duty off-road equipment when not in use, and ensuring that construction equipment is properly maintained and equipped with noise-reduction intake and exhaust mufflers and shrouds, in accordance with manufacturers’ recommendations. For the proposed action, the City has developed a tailored list of construction noise controls to be implemented during construction activities, which includes the following:
Timing Limitations and Notifications
• Construction activities shall be limited to the hours between 7:00 a.m. and 7:00 p.m., Monday through Friday, unless permission is granted by the City.
• Prior to construction, notify businesses, residences, and other noise-sensitive land uses within 100 feet of the site of the construction schedule, in writing, and provide a written schedule of “noisy” construction activities to the adjacent land uses and nearby residences.
• Designate a "disturbance coordinator" who shall be responsible for responding to any complaints about construction noise. The disturbance coordinator shall determine the cause of the noise complaint (e.g., bad muffler, etc.) and require that reasonable measures be implemented to correct the problem. Conspicuously post a telephone number for the disturbance coordinator at the construction site and include it in the notice sent to neighbors regarding the construction schedule.
Proper Maintenance, Muffling, & Noise Barriers
• During construction activities, utilize the best available noise suppression devices and techniques, equip internal combustion engine-driven equipment with intake and exhaust mufflers that are in good condition and appropriate for the equipment, and prohibit unnecessary idling of internal combustion engines. • Utilize "quiet" air compressors and other stationary noise sources where technology exists. • Construct temporary noise barriers to screen stationary noise-generating equipment when located near sensitive land uses.
• Construct a solid plywood fence along the eastern property line, where feasible, to shield the adjoining residential receptors from construction work. The noise barrier should be 8-foot-tall noise to block direct line-of-sight with City of Santa Rosa

ground-level receptors. If such a fence is not feasible, consider other noise barrier options that would contribute to attenuating construction noise at the eastern property line by approximately 5 dBA. • Control noise from construction workers’ radios to a point where they are not audible at existing residences bordering the project site.
Staging & Stockpiling
• Locate stationary noise-generating equipment such as air compressors or portable power generators as far as possible from sensitive receptors.
• Construction staging areas shall be established at locations that would create the greatest distance between the construction-related noise source and noise-sensitive receptors during all project construction. • Locate material stockpiles, as well as maintenance/equipment staging and parking areas, as far as feasible from residential receptors.
Project Environmental Protection Action 2 – Groundborne Vibration As a standard condition of development approval, the City requires the implementation of measures for the control of construction-generated groundborne vibration. For the proposed action, the City has developed a tailored list of groundborne vibration controls to be implemented during construction activities, which include the following:
• Large vibratory rollers shall not occur on the construction site within 14 feet of the site boundaries shared with existing buildings to the east. The dropping of heavy equipment or materials shall not occur on the construction site within 13 feet of the site boundaries shared with existing buildings to the east. All other equipment shall not be used within 5 feet of the east boundary of the site.
• Smaller equipment shall be used to minimize vibration levels to below 0.3 in/sec PPV at the property lines adjoining adjacent buildings. For example, a smaller vibratory roller, such as the Caterpillar model CP433E vibratory compactor, could be used when compacting materials within 20 feet of the adjacent conventional buildings; • Use alternative methods for breaking up existing pavement, such as a pavement grinder, instead of dropping heavy objects, within 20 feet of conventional buildings.
• A Disturbance Coordinator will be designated to be responsible for registering and investigating claims of excessive vibration. The contact information of such person shall be clearly posted on the construction site. • A list of all heavy construction equipment to be used for the proposed action known to produce high vibration levels (e.g., tracked vehicles, vibratory compaction, jackhammers, clam shovel drop, and vibratory roller, etc.) shall be submitted to the City by the contractor.

Project Environmental Protection Action 3 – Operational Noise If the building design and orientation changes from that evaluated in the 2024 CEQA Checklist, then the City will require the building design to be further reviewed by an acoustical consultant to evaluate the potential noise generated and to demonstrate the necessary noise controls to meet ambient noise level conditions. Noise control features such as sound attenuators, sound enclosures, baffles, and barriers will be identified and evaluated to demonstrate that mechanical equipment noise would not exceed City thresholds at noise-sensitive locations surrounding the project site.

Project Environmental Protection Action 4 – Construction Pollutant Mitigation Plan A Health Risk Assessment meeting the requirements of Mitigation Measure MM 3.3.5 of the Specific Plan Program EIR was prepared for the proposed action (Illingworth & Rodkin 2023). In accordance with PEIR Mitigation Measure MM
3.3.5, the Health Risk Assessment identified a construction pollutant mitigation plan as part of the proposed action that reduces concentrations of air quality emissions below Bay Area Air Quality Management District thresholds of significance during construction. Based on the results of the Health Risk Assessment, the construction pollutant mitigation plan for the proposed action is as follows:
• All construction equipment larger than 25 horsepower used at the site for more than two continuous days or 20 hours total shall meet U.S. EPA Tier 4 emission standards for PM (PM10 and PM2.5), if feasible. • If use of Tier 4 equipment is not feasible, use equipment that meets U.S. EPA emission standards for Tier 2 or 3 engines and include particulate matter emissions control equivalent to CARB Level 3 verifiable diesel emission control devices that altogether achieve a 70 percent reduction in particulate matter exhaust in comparison to uncontrolled equipment.
• Alternatively (or in combination), use electrical or non-diesel fueled equipment. • The City and Design-Build contractor may also develop another construction operations plan demonstrating that the construction equipment used on-site would achieve a reduction in construction diesel particulate matter emissions by 70 percent or greater. Elements of the plan could include a combination of some of the following measures, and would be subject to review by an air quality expert and approved by the City prior to construction:
o Implementation of No. 1 above to use Tier 4 or alternatively fueled equipment, o Installation of electric power lines during early construction phases to avoid use of diesel generators and compressors,
o Use of electrically-powered equipment,
o Forklifts and aerial lifts used for exterior and interior building construction shall be electric or propane/natural gas powered,
o Change in construction build-out plans to lengthen phases, and o Implementation of different building techniques that result in less diesel equipment usage.
