5. Environmental Analysis <br />Chapter 5 examines the environmental impacts associated with the proposed project. This chapter is divided <br />into subchapters (or sections) for respective environmental issue areas that were determined during the <br />scoping process to need further study in the EIR. <br />The scope of the environmental analysis was determined using the Initial Study and Notice of Preparation <br />NOP that was published October 2008, the NOP published in January 2009, as well as incorporating public <br />and agency comments received during the NOP comment periods (see Appendix 13). Enviironmental issues <br />and their corresponding sections are listed below- <br />* 5-1 Air Quality <br />o 5.2 Noise <br />• 5.3 Traffic and Circulation <br />Sections 5.1 through 5.3 provide a detailed discussion of the environmental setting, impacts associated with <br />the proposed project, and any mitigation measures that may be required to reduce significant impacts. The <br />residual impacts following the i rn p le me ntati on of any mitigation nneasure wouId also be discussed in these <br />sections. (iVau-6 <br />cf7w) <br />As presented in the Initial Study prepared for the proposed project (Appendix A), some specific issues under <br />each of the environmental topics (air quality, noise, traffic and circulation) were determined to not be <br />significantly affected by implementation of the project, and therefore are not included for further discussion. <br />Organization of Environmental Analysis <br />To assist the reader in comparing information about the respective environmental issues, each section <br />(Sections 5.1 to .3) is organized as follows: <br />• Impacts Identified in the Santa Ana Second Main Tracy E I R (2002) <br />• Environmental Setting <br />0 Thresholds of Significance <br />• Environmental Impacts <br />• cumulative Impacts <br />• Existing Regulations and Standard Conditions <br />+ Level of Significance Before Mitigation <br />• litigation Measures <br />• Level of Significance After Mitigation <br />In addition, the Executive Su m rn ary includes a table showing all the impacts by environmental topic. <br />EalrbavenlLincoln and Santa ClaralLincoln Intersection Modifications City of Santa Ana • Page 5 -1 <br />SuPlement to the Santa Ana Second Haan a c4 Proy'ect EIR Resolution No. 2009 -034 <br />Page 49 of 130 <br />
