4.1 – Air Quality Draft Environmental Impact Report February 2021 14800 W. Schulte Road Logistics Center 4.1-27 PDF-AQ/GHG-1 The buildings shall be designed to achieve a minimum the Leadership in Energy and Environmental Design (LEED) Certified goal identified by the LEED Green Building Rating System to conserve resources, including energy and renewable resources. PDF-AQ/GHG-2 Install 2%–3% skylights in warehouse buildings for natural lighting and to reduce electricity consumption from warehouse lighting. PDF-AQ/GHG-3 Install conduit for future electric truck charging capabilities. PDF-AQ/GHG-4 Install conduit for 33 future electric vehicle charging spaces. PDF-AQ/GHG-5 Designate 21 parking spaces for clean air/electric vehicle/vanpool parking. Construction Emissions from the construction phase of the Project were estimated using California Emissions Estimator Model (CalEEMod) Version 2016.3.2. Construction scenario assumptions, including phasing, equipment mix, and vehicle trips, were based on information provided by the Project applicant and CalEEMod default values when Project specifics were not known. For purposes of estimating Project emissions, and based on information provided by the Project applicant, it is assumed that construction of the Project would commence in July 20217 and would last approximately 10 months, ending in April 2022. The analysis contained herein is based on the following assumptions (duration of phases is approximate): • Site Preparation: 2 weeks (July 1, 2021 – July 15, 2021) • Grading: 1 month (July 16, 2021 – August 31, 2021) • Building Construction: 7 months (September 1, 2021 – March 30, 2022) • Paving: 1 month (April 1, 2022– April 30, 2022) • Architectural Coating: 3 months (February 1, 2022 – April 30, 2022) Grading would involve 37.47 acres and balanced cut and fill. The construction equipment mix and vehicle trips used for estimating the Project-generated construction emissions are shown in Table 4.1-6. Table 4.1-6. Construction Scenario Assumptions Construction Phase One-Way Vehicle Trips Equipment Average Daily Worker Trips Average Daily Vendor Truck Trips Total Haul Truck Trips Equipment Type Quantity Usage Hours Site Preparation 18 6 0 Tractors/Loaders/ Backhoes 4 8 Rubber Tired Loaders 3 8 7 The analysis assumes a construction start date of July 2021, which represents the earliest date construction would initiate. Assuming the earliest start date for construction represents the worst-case scenario for criteria air pollutant and GHG emissions because equipment and vehicle emission factors for later years would be slightly less due to more stringent standards for in-use off-road equipment and heavy-duty trucks, as well as fleet turnover replacing older equipment and vehicles in later years.
