Project Emissions <br />In support of the consistency analysis below that describes the Project's compliance with, or <br />exceedance of performance -based standards included in the regulations and policies outlined in <br />the applicable portions of the 2022 Scoping Plan, the 2020-2045 RTP/SCS, and the City's <br />Climate Action Plan (CAP), quantitative calculations are provided below. <br />The Project would generate direct and indirect GHG emissions as a result of different types of <br />emissions sources, including the following: <br />• Construction: emissions associated with demolition of the existing uses, grading, and <br />construction -related equipment and vehicular activity; <br />• Area source: emissions associated with landscape equipment; <br />• Energy source (building operations): emissions associated with electricity and natural gas <br />use for space heating and cooling, water heating, energy consumption, and lighting; <br />• Stationary source: emissions associated with stationary equipment (e.g., emergency <br />generators); <br />• Mobile source: emissions associated with vehicles accessing the Project Site; <br />• Solid Waste: emissions associated with the decomposition of the waste, which generates <br />methane based on the total amount of degradable organic carbon; and <br />• Water/Wastewater: emissions associated with energy used to pump, convey, deliver, and <br />treat water. <br />Construction Emissions <br />Project construction is anticipated to be completed in 2027 with occupancy the same year. The <br />GHG emissions associated with construction of the Project were calculated for each year of <br />construction activity. Construction of the Project is estimated to generate a total of 3,523 MTCO2e <br />(refer to Table 12). As recommended by the SCAQMD, the total GHG construction emissions <br />were amortized over the 30-year lifetime of the Project (i.e., total construction GHG emissions <br />were divided by 30 to determine an annual construction emissions estimate that can be added to <br />the Project's operational emissions) in order to determine the Project's annual GHG emissions <br />inventory. This results in annual Project construction emissions of 117 MTCO2e. <br />Table 12 <br />Combined Construction -Related Emissions (MTCO,e) <br />Year <br />MTCO2ea <br />2024 <br />293 <br />2025 <br />773 <br />2026 <br />1,517 <br />2427Q <br />Total <br />3,523 <br />Cabrillo Town Center City of Santa Ana <br />Technical Memorandum August 2023 <br />City Council 18 — 543 10/3/2023 <br />
