ATTY/RESO.0035/CC RESO CERTIFYING FINAL EIR – 1548 MAPLE REV: 04-30-18 PR Page 12 of 49 • All visible mud or dirt tracked-out onto adjacent public roads shall be removed using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. • All vehicle speeds on unpaved roads shall be limited to 15 mph. • All roadways, driveways, and sidewalks to be paved shall be completed as soon as possible. Building pads shall be laid as soon as possible after grading unless seeding or soil binders are used. • Idling times shall be minimized either by shutting equipment off when not in use or reducing the maximum idling time to 5 minutes (as required by the California airborne toxics control measure Title 13, Section 2485 of California Code of Regulations [CCR]). Clear signage shall be provided for construction workers at all access points. • All construction equipment shall be maintained and properly tuned in accordance with manufacturer's specifications. All equipment shall be checked by a certified mechanic and determined to be running in proper condition prior to operation. • A publicly visible sign shall be posted with the telephone number and person to contact at the City of Redwood City regarding dust complaints. This person shall respond and take corrective action within 48 hours. The BAAQMD phone number shall also be visible to ensure compliance with applicable regulations. Finding: Implementation of Mitigation Measure AIR-1 would reduce the project- related impacts related to air quality standards to a less-than-significant level. Facts in Support of Finding: This mitigation measure appropriately identifies the Basic Construction Mitigation Measures developed by BAAQMD that would be implemented through all construction contracts and specifications for the proposed project. Impact AIR-2: Operation of the proposed project would expose future residents of the project site to toxic air contaminants. Mitigation AIR-2: The following measures shall be implemented by the project applicant and approved by the City through the final design process to reduce TACs and particulate matter indoors to a level sufficient to achieve compliance with BAAQMD health risk thresholds: • The project applicant shall provide an HVAC system with a control efficiency sufficient to result in a reduction of a minimum 80.0 percent of particulates of 2.5 microns or less, such as Minimum Efficiency Reporting Value (MERV)-13 filters or greater, for indoor air filtration systems . The ventilation system shall be certified to achieve the stated performance effectiveness from indoor areas. • The project applicant shall locate all air intakes as far away from US 101 as feasible. • The project applicant shall disclose to potential occupants of the project that the proximity of the project site to the freeway could result in increased long-term health risks. The disclosure shall indicate the specifications for the installed air filtration system. 7.A. - Page 49
