Cabrillo at First Mixed-Use Residential Air Quality, Global Climate Change, HRA, and Energy Impact Analysis 1 19386 1. INTRODUCTION This section describes the purpose of this air quality, global climate change, health risk assessment, and energy impact analysis, project location, proposed development, and study area. Figure 1 shows the project location map and Figure 2 illustrates the project site plan. PURPOSE AND OBJECTIVES This study was performed to address the possibility of regional/local air quality impacts and global climate change impacts, from project related air emissions. The objectives of the study include: ▪ documentation of the atmospheric setting ▪ discussion of criteria pollutants and greenhouse gases ▪ discussion of the air quality and global climate change regulatory framework ▪ analysis of the construction related air quality and greenhouse gas emissions ▪ analysis of the operations related air quality and greenhouse gas emissions ▪ discussion of the health risk impacts ▪ analysis of the conformity of the proposed project with the SCAQMD AQMP ▪ analysis of the project’s energy use during construction and operation ▪ recommendations for mitigation measures The City of Santa Ana is the lead agency for this air quality and greenhouse gas analysis, in accordance with the California Environmental Quality Act authorizing legislation. Although this is a technical report, every effort has been made to write the report clearly and concisely. To assist the reader with terms unique to air quality and global climate change, a definition of terms has been provided in Appendix A. PROJECT LOCATION The 1.40-acre project site is located at the southwest corner of the intersection of First Street and Cabrillo Park Drive in the City of Santa Ana, California. The project site is located within the Metro East Mixed-Use Overlay District (MEMU). It is understood that the project will be subject to the measures outlined in the 2018 Mitigation Monitoring and Reporting Program (MMRP) for the Metro East Mixed-Use Overlay District Expansion and Elan Development Projects (see Section 6, Emissions Reduction Measures). A vicinity map showing the project location is provided on Figure 1. PROJECT DESCRIPTION The proposed project involves construction of a mixed-use residential project consisting of 35 townhome dwelling units, including six live/work units. Vehicular access is proposed via one right turn in/out only driveway at First Street. Figure 2 illustrates the proposed site plan. PHASING AND TIMING The proposed project is anticipated to be operational in 2023. The project is anticipated to be built in one phase with project construction starting no sooner than the mid-May 2022 and being completed by mid- August 2023. Even if construction was to occur any time after the respective dates, the analysis represents “worst-case” since emission factors for construction decrease as time passes and the analysis year increases due to emission regulations becoming more stringent.1 1 As shown in the California Emissions Estimator Model (CalEEMod) User’s Guide Version 2020.4.0, Section 4.3.2 “OFFROAD Equipment” as the analysis year increases, emission factors for the same equipment pieces decrease due to the natural turnover of older equipment being replaced by newer less polluting equipment and new regulatory requirements. 16/27/2022 Planning Commission 2 –54
