ATTY/RESO.0034/PC RESO RECOMMENDING CEQA APPROVAL – 505 E. BAYSHORE – EXHIBIT A REV: 05-12-23 JB Page 16 of 30 through 45 of the DEIR, which includes a full statement of the impact and applicable mitigation measures and is hereby incorporated herein in its entirety. 2. Air Quality Impact AIR-3: Construction activities associated with the project, particularly during site preparation and grading, would temporarily generate fugitive dust in the form of PM10 and PM2.5. Sources of fugitive dust would include disturbed soils at the construction site and trucks carrying uncovered loads of soils. Unless properly controlled, vehicles leaving the site would deposit mud on local streets, which could be an additional source of airborne dust after it dries. Standard Permit Conditions of Approval: The following standard condition of approval will be implemented during all phases of construction to control dust and exhaust at the project site: • Water active construction areas at least twice daily or as often as needed to control dust emissions. • Cover trucks hauling soil, sand, and other loose material and/ or ensure that all truck hauling such materials maintain at least two feet of freeboard. • Remove visible mud or dirt track-out onto adjacent public roads using wet power vacuum street sweepers at least once per day. The use of dry power sweeping is prohibited. • Enclose, cover, water twice daily or apply non-toxic soil binders to exposed stockpiles (dirt, sand, etc.). • Pave new or improved roadways, driveways, and sidewalks as soon as possible. • Lay building pads as soon as possible after grading unless seeding or soil binders are used. • Replant vegetation in disturbed areas as quickly as possible. • Install sandbags or other erosion control measures to prevent silt runoff to public roadways. • Minimize idling times either by shutting off equipment 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). Provide clear signage for construction workers at all access points. • Maintain and properly tune construction equipment in accordance with manufacturer’s specifications. Check all equipment by a certified mechanic and record a determination of running in proper condition prior to operation.
