I the project area, Staff at the City of Santa Ana will be consulted to identify the intersections that will be evaluated. The future baseline traffic volumes will be forecast by considering the effects of general area-wide growth and the cumulative volumes of traffic that would be generated by other proposed development projects in the area. The impacts of the proposed project will be determined by estimating the levels of traffic that the activities at the athletic fields and park would generate then conducting a before-and-after analysis of traffic conditions on the streets and intersections in the site vicinity (Le., traffic conditions with and without the proposed project). The volume of traffic that would be generated by the athletic fields and park will be based on the trip generation rates from the Institute of Transportation Engineers' Trip Generation manual. The traffic analysis will address the project's impacts during the afternoon peak period on a typical weekday and on a weekend day. The analysis will also address the anticipated parking impacts of the proposed project. Potential measures for mitigating the adverse traffic and parking impacts (if any) will be identified -in consultation with the City of Santa Ana. The analysis methodology, assumptions, and findings will be summarized In report sections suitable for Insertion Into the environmental document. Air Quality Potential air quality impacts associated with construction and operation of the project will be analyzed in the EIR. The analysis will be based on the South Coast Air Quality Management District's (SCAQMD) methodology for projects in the South Coast Air Basin (SOCAB). Air pollutant emissions will be quantified using the CALEEMOD computer model for both the construction and operational phases. Construction modeling will be based on construction phasing, the construction schedule, and anticipated equipment for each type of construction activity, Air pollutant emissions will be compared to SCAQMD's regional thresholds of significance to determine the significance of project-related construction emissions due to the expansion of the stadium and reconfiguration of the athletic field. Onsite localized project-related emissions associated with vehicle exhaust and dust generated during the construction phase will also be evaluated against SCAQMD's screening-level localized significance thresholds (LSTs) for projects under five acres to determine whether sensitive residential uses along local roadways would be exposed to air pollution that exceeds the ambient air quality standards (AAQS). Project-related emissions will also be evaluated relative to consistency with the air quality management plan. Greenhouse Gas Emissions The EIR will quantify greenhouse gas (GHG) emissions for area sources, energy (purchased energy, energy from water transport, use, and treatment), waste disposal, and transportation emissions sources generated by the project. The potential effects of GHG emissions, history of GHG emissions regulation In California, and project- related GHG emissions will be discussed. Project consistency with the CARB Scoping Plan's statewide GHG emissions reduction strategies will also be reviewed. Noise and Vibration The existing field is currently used for physical education and sporting events during daylight hours. With the addition of lights, the field and courts will be used during evening hours, which will increase noise levels until closing, which is likely to be 10:00 PM, For the purposes of this scope, we assume that no bleachers will be installed onsite and amplified sounds systems will not be allowed. The CEQA document will evaluate potential impacts resulting from the construction and operation of the project. The noise analyses will be consistent with the noise compatibility standards of the District and the City of Santa Ana. The short-term construction analyses will focus on potential noise and vibration impacts on sensitive land uses such as the onsite school classrooms and local residential uses. Based on the anticipated construction schedule and equipment list, construction-related noise and vibration levels will be calculated for THE PLANNING CENTER IPROPOSALWIL:A.R ii:TERMEDiATESCHWLAT"LEMRELDIN.PR7JEtJcT.:. 25C-14
