01uc:adoii 1st City of Santa Ana Updated Proposal for the 301 East Jeanette Lane Residential Project Mitigated Negative Declaration Existing Conditions. The project is located.within the South. Coast Air Basin (SCAB), which is under theJurisdiction of the South Coast Air Quality Management District(SCAQMD). Baseline meteorological and air quality data developed through the California Air Resources Board (CARB) will be utilized for the description of existing ambient air quality. Airquality data from the nearest air quality monitoring station will be included to help highlight existing airquality local to the project area, Construction-ReiatedEmissions. Based on data provided by the project applicant, emissions generated during demolition, earthwork, and construction will be quantified. A general description of the major phases of construction and their timing will be required. The air pollutant emissions during construction will be compared to the SCAQMD Regional Thresholds of Significance. RBF will also qualitatively discuss naturally occurring asbestos impacts. Lonp-Term Emissions. RBF will quantify operational emissions and provide a comparison to the SCAQMD significance thresholds. The emissions will be quantitatively derived utilizing the CaIEEMod model. Primary sources of emissions will be related to area sources and Iocal/regional vehicle miles traveled, Project consistency with the SCAQMD's 2007 Air Qualify Management Plan will also be provided. Localized Emissions. The project is located within the SCAQMD's Source Receptor Area 17 (Central Orange County). Based on localized meteorological data for SRA 17, RBF will analyze localized impacts based upon the SCAQMD's Localized Significance Thresholds (LST) methodology, This localized analysis will account for sensitive receptors in the project vicinity. The results of the construction-related and long-term operational air quality modeling will be incorporated into the Initial Study. Mitigation measures will be incorporated to reduce impacts on a local and regional basis (if applicable). D. BIOLOGICAL RESOURCES Given the developed nature of the project area and disturbed nature of the project site, no sensitive biological species or habitat is expected to occur on-site. On-site conditions will be confirmed. E. CULTURAL RESOURCES The analysis will cite the provisions of CEQA Guidelines 15064.5 (Historical and Archaeological Resources). The analysis will include site-specific historical research at the California State University, Fullerton Information Center. This analysis will also include a search of Native American Heritage Commission files. F. GEOLOGY AND SOILS Based upon reference support information to be provided by the City andlor applicant, the analysis will identify existing regional and site specific geologic and soils constraints, The project will be evaluated for its potential to expose people or structures to potential substantial adverse effects involving fault rupture, strong seismic ground shaking, seismic-related ground failure (i.e., liquefaction), and landslides. Project areas potentially subject to significant grading impacts, existing topography and landform modifications, and wind/water erosion potential of the soils will be evaluated, Unstable geolog is units/soils will also be evaluated. This section will also identify recommended mitigation to avoid or reduce potential impacts to the extentfeasible, such as erosion control criteria and grading requirements, to ensure consistencywith Cityof Santa Ana grading standards/policies.
