Environmental Consulting Services (too East First American Way) I City of Santa Ana ■ Identify existing land uses in the project area along with existing sources of noise, including the nearby roadways. ■ Quantify existing noise conditions in the project area based on noise measurements. Five short-term noise measurements (io-i5 minutes in duration) and one long-term measurement (24 hour) are included within this scope of work. The short-term noise measurements will be conducted at potentially sensitive noise receivers and the long- term measurement will be conducted on the project site. ■ Evaluate construction noise based on construction equipment data to be provided by the City and noise modeling methods recommended by the U.S. Department of Transportation. ■ Model conditions using traffic data provided by LLG, traffic noise along project -adjacent roadways and noise generated by the neighboring land uses, using the most recent version of the FHWA-approved traffic noise prediction model. Key roadway segments will be assessed, to adequately determine existing and future conditions. ■ Predict noise from the on -site operations (i.e., traffic, parking lot, and project equipment) at the nearest noise - sensitive land uses using data from similar, prior projects and available published data. ■ Give special consideration to nearby sensitive receptors, including existing residences and hotel. The significance of noise impacts will be assessed based on relevant thresholds (City of Santa Ana, State and federal). If significant noise impacts are identified, mitigation measures to reduce impacts to a less -than -significant level will be recommended. The findings of the noise analysis will be included in a technical report provided as an Appendix to the IS/MND and summarized in the noise section of the IS/MND. (: OlturrO Rei) ,r:e, 1 valuafloo ICF recommends that a records search, locality search, site visit, and assessment report be prepared to evaluate the potential for archeological and paleontological resources to be found on the project site. This evaluation will: ■ Conduct research records at the South Central Coastal Information Center of the California Historical Resources Information System (CHRIS). ■ Survey the site in accordance with professional standards and methodologies. For costing, we assume no resources will be identified in the field requiring evaluation. ■ Will follow the Society of Vertebrate Paleontology's guidelines related to paleontological resources, which are widely accepted as an industry standard. ■ Assess the project -related risks to paleontological resources by utilizing published geologic and paleontological literature and museum databases, likely including the databases of the Los Angeles County Museum of Natural History, San Bernardino County Museum, University of California Riverside, California Academy of Sciences, and University of California Museum of Paleontology in Berkeley. The findings of the cultural resource evaluation will be included in a technical report provided as an Appendix to the IS/MND and summarized in the Cultural Resource section of the IS/MND. Task 3. Prepare Administrative Draft IS/MND ICF will prepare an Administrative Draft IS/MND for the project, which will include an evaluation of the environmental resources contained in the CEQA Environmental Checklist. The analyses will include: ■ Discussion of existing conditions; ■ Identification, analysis, and evaluation of all potential environmental impacts; ■ Examination and recommendation of feasible ways to eliminate or minimize adverse environmental impacts; and, ■ Discussion of cumulative impacts. We will provide substantial evidence to support the findings in the CEQA Environmental Checklist, providing both quantitative and qualitative analysis. To support the conclusions of the analysis for some of the topic areas, we will use the technical studies prepared in Task 2.
