3.0 Environmental impact Checklist • All roadways, driveways, and sidewalks to be paved shall be completed as soon as feasible. 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 ReguIations). • 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 visible emissions evaluator. • Post a publicly visible sign with the telephone number and person to contact at the lead agency regarding dust complaints.This person shall be responsible and take corrective action within 48 hours. The Air District's phone number shall also be visible to ensure compliance with applicable regulations. Mitigation Measure AIR-2:Demolition of the existing homes and buildings shall be performed consistent with District Regulation 11,Rule 2:Asbestos Demolition,Renovation and Manufacturing. Mitigation Measure AIR-3:Only one phase of construction shall occur at a time(e.g.,paving would occur prior to development of the homes). Operation The project meets the screening criteria for operational impacts because it is well below the screening threshold of 325 dwelling units.The project would be constructed using standard construction methods identified in the URBEMIS program. Given the small size of the project, the modest increases in traffic projected for the project, and that it is an infill project(versus a greenfield for which the screening criteria were modeled),the long-term occupancy of the homes would have a less than significant impact on air quality. c) Result in a cumulatively considerable net increase of any criteria pollutant for which the project region is in nonattainment under an applicable federal or state ambient air quality standard(including releasing emissions that exceed quantitative thresholds for ozone precursors)? Less-than-Significant Impact. According to the 2012. BAAQMD CEQA Guidelines, if a project requires a General Plan Amendment(GPA) or would generate more VMT than anticipated under a previous land use designation,there could be a significant cumulative impact. The proposed project would not require a GPA because implementation of the project would be consistent with allowable development identified for the project site's land use designation. The project site is designated for medium density residential development in the City's General Plan, and regional air quality modeling has therefore already factored in the vehicle trips associated with the proposed construction and development of the project site.The project would not result in a cumulatively considerable new increase in any criteria pollutant.Impacts would be less than significant.
