The Academy Charter High School MND j City of Santa Ana Planning Division <br />INCE and has conducted numerous analyses for projects involving re -development and school projects that are <br />adjacent to residential and sensitive uses. <br />Existing residences are located immediately adjacent to the project site, which could be impacted by noise from <br />project construction and/or operation. Additionally, on -site classrooms, outside recreational school uses, and <br />offsite residential land uses adjacent to the local arterial roads are also considered to be noise -sensitive and <br />could be impacted by project traffic. <br />To identify the existing ambient noise environment in the project area, five short-term (10-15 minutes in <br />duration) ambient noise measurements will be conducted at noise -sensitive locations in and around the project <br />site. The noise measurements will be conducted using equipment and methods as proscribed by the American <br />National Standard Institute and consistent with the standards of the practice for community noise analysis. <br />Using the noise measurements as a baseline, potential construction noise impacts on nearby noise -sensitive <br />land uses will be evaluated based on construction equipment data to be provided by the project applicant and <br />noise modeling methods developed by the Federal Highway Administration (FHWA). Long-term (operational) <br />noise effects from the project will also be addressed and will include evaluation of on -site activity noise levels <br />and the ability of the noise to effect surrounding uses. Further, traffic noise will be assessed using the project's <br />traffic volume data and the FHWA Traffic Noise Model version 2.5. <br />The significance of noise impacts resulting from the proposed project will be assessed based on relevant <br />thresholds (city, state and federal). If significant noise impacts are identified, mitigation measures to reduce <br />impacts to a less -than -significant level (where feasible) will be recommended. The results of the noise analysis <br />will be provided in the noise section of the ISIMND. Any technical data or modeling will be provided in an <br />appendix. <br />Cultural Resource Evaluation <br />ICF recommends that a records search, locality search, and assessment report be prepared to evaluate the <br />potential for archeological and paleontological resources to be found on the project site. This evaluation will: <br />• Conduct a literature and records search at the South Central Coastal Archaeological Information Center <br />of the California Historical Resources Information System at California State University, Fullerton, to <br />determine If any prehistoric or historical cultural resources have been recorded within project area. <br />• Review published geologic and paleontological literature and museum databases, including the Los <br />Angeles County Museum of Natural History database. <br />• In coordination with the City, ICF will contact with the Native American Heritage Commission and local <br />Native Americans regarding the project. <br />Because the project area is completely paved and developed, an archaeological field survey will not be <br />conducted. <br />The findings of the cultural and paleontological resource investigations will be used to provide an assessment of <br />the sensitivity of the project area for prehistoric archaeological and paleontological resources. This will be <br />summarized in the Cultural Resource section of the ISIMND. The MND will also provide mitigation measures, if <br />necessary. <br />Traffic Impact Analysis (TIA) <br />As a subconsultent to ICF, Fehr & Peers will prepare a project -specific TIA to evaluate the traffic related impacts <br />of the proposed project. The TIA will be summarized in the traffic section of the ISIMND and included as an <br />appendix. Preparation of the TIA includes the following tasks: <br />H Confirm Traffic Analysis Scope. Fehr & Peers and other members of the project team would meet with <br />the City of to review and approve our approach to preparing the traffic study. Specific items that would be <br />addressed in this scoping memorandum include: <br />
