4. Mitigation Monitoring and Reporting Program Harbor View Project 8-3 ESA / 170951 Final Environmental Impact Report October 2022 ATTY/RESO.0085/PC RESO RECOMMENDING CEQA – EXHIBIT B REV: 10-28-2022 VR TABLE 8-1 HARBOR VIEW PROJECT MITIGATION MONITORING AND REPORTING PROGRAM Impact Mitigation Measure Implementation Responsibility Action Monitoring Party Monitoring Schedule 4.2 Air Quality and Climate Change Impact AIR-1: Construction activities associated with the Project would generate fugitive dust and criteria air pollutants, and exceed the BAAQMD significance threshold for construction criteria air pollutant NOx. Impact AIR-1.CU: Development of the Project, combined with cumulative development citywide, would result in cumulative air quality impacts. Mitigation Measure AIR -1A: Implement BAAQMD Basic Construction Mitigation Measures. The Project sponsor shall require construction contractors to implement the following applicable BAAQMD Basic Construction Mitigation Measures to reduce emissions of fugitive dust and equipment exhaust: All exposed surfaces (e.g., parking areas, staging areas, soil piles, graded areas, and unpaved access roads) shall be watered two times per day. All haul trucks transporting s oil, sand, or other loose material off -site shall be covered. All visible mud or dirt track-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 vehic le 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. Post a publicly visible sign with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations. Post a publicly visible sign with the telephone number and person to contact at the Lead Agency regarding dust complaints. This person shall respond and take corrective action within 48 hours. The BAAQMD’s phone number shall also be visible to ensure compliance with applicable regulations. Project Applicant or designee Construction contractor(s) Measure is incorporated into construction specifications Construction contractor carries out construction pursuant to contract specifications City of Redwood City – Building Division to observe Project construction and respond to any dust complaints Prior to issuance of demolition and/or building permits During all Project site preparation and construction activities Mitigation Measure AIR -1B: Implement BAAQMD additional construction mitigation measures. The Project sponsor shall require construction contractors to implement the following measures, recommended for projects with construction emissions above significance thresholds to further reduce fugitive dust and exhaust emissions. All exposed surfaces shall be watered at a frequency adequate to maintain minimum soil moisture of 12 percent. Moisture content can be verified by lab samples or moisture probe. All excavation, grading, and/or demolition activities shall be suspended when average wind speeds exceed 20 mph. Wind breaks (e.g., trees, fences) shall be installed on the windward side(s) of actively distur bed areas of construction. Wind breaks should have at maximum 50 percent air porosity. Vegetative ground cover (e.g., fast-germinating native grass seed) shall be planted in disturbed areas as soon as possible and watered appropriately until vegetation is established. The simultaneous occurrence of excavation, grading, and ground-disturbing construction activities on the same area at any one time shall be limited. Activities shall be phased to reduce the amount of disturbed surfaces at any one time. All trucks and equipment, including their tires, shall be washed off prior to leaving the site. Site accesses to a distance of 100 feet from the paved road shall be treated with a 6- to 12-inch compacted layer of wood chips, mulch, or gravel. Sandbags or other erosion control measures shall be installed to prevent silt runoff to public roadways from sites with a slope greater than one percent. Minimizing the idling time of diesel powered construction equipment to two minutes. Project Applicant or designee Const ruction contractor(s) D evelop plan demonstrating that the off -road construction equipment would achieve reductions specified in measure. Implement emission reduction measures City of Redwood City – Planning Division to review/confirm plan City of Redwood City – Building Division to confirm adherence to measure Prior to issuance of demolition and/or building permits During all Project site preparation and construction activities
