More specifieaNy, Chambers Group will update the wasting noise environment, applicable federal, State and local regulations and guidelines; identify any new noise impacts associated with buildout of the updated General Plan and Zoning Code; and present strategies to reduce those impacts.The following tasks will be completed as part of the noise Impact analysis and report Task 1. Existing Setting jkikaligasmank Chambers Group will take up to twelve representative baseline noise measurements throughout the City In order to update the existing noise environment. These representative samples may include vehicular noise, rail noise and stationary noise. Noise sources wiN be observed and documented and traffic mix will be noted. Noise measurement locations will be presented on a map, to be Included in the Noise Report Existing Traffic Noise Contours,Chambers Group will model existing noise contours for acoustically significant General Plan arterials utilizing the Federal Highways Administration (FHWA) Roadway Noise Model (FHWA-RD-77-105)or Sourd32/2000. Existina Rail Noise Contour', information presented In the existing Noise Element Technical Memorandum will be verified. Available traffic data from the Burlington Northern Sante Fe Railway and Southern Pacific will be collected and used to identify existing rail noise contours.jf Satiric rail noise contours are available and acceptable to the City. mods in a of existing rail noise wI not be completed. Otherwise, Chambers Group wIN model existing rail noise contours utilizing Federal Transit Administration (ETA) noise and dbration Impact assessment procedures and the FTA endorsed freight rail analysis spreadsheet tod developed for the Chicago Rail Efficiency and Transportation Efficiency(CREATE) program. Otherwise, Chambers Group will model existing and future rail noise contours utilizing Federal Trend.Administration (FTA) noise and vibration impact assessment procedures- and the FTA endorsed freight rail analysis spreadsheet tool developed for the Chicago Rail Efficiency and Transportation Efficiency(CREATE)program. Major Stationary Noise Imoacts. Chambers will identify major stationary noise sources, associated with the General Plan update and Redevelopment Plan Amendment. This data will be included in the Noise Study. Major sources will be measured as part of noise measurement task (above). Joyce Powers July 29, 2009 Page 6 Task 2. Impact Analysts Fuses Trelflc Hoies Contour. Chambers Group will review gS10nest buildout volumes and any recent or proposed roadway re-alignments (since the last GP update)for all City arterials. If any acousticaly significant changes have occurred since the last GP Update or are proposed for the future Chambers wit model future noise contours for these road segments utilizing the Federal Highways Administration (FHWA) Roadway Noise Model (FHWA-RD-77-108) or Sound32/2000. Far purposes of this proposal. Chambers will future noise contours for up five General Plan arterials. Future Rall Noise Contours, If future rail noise contours are available and acceptable to the City, modeling of existing raN noise MI not be completed. Otherwise, Chambers Group will model future rail noise contours utilizing Federal Transit Administration (FTA) noise and vbration Impact assessment procedures and the FTA endorsed freight rail analysis spreadsheet tool developed for the Chicago Rail Efficiency and Transportation Efficiency(CREATE)program. Stationary fides Imparts. Stationary noise source impacts to land uses associated with the proposed General Plan Update and Redevelopment Plan Amendment sell be analyzed. It is noted that most stationary noise sources throughout the City are industrial in nature and are expected to be located N areas zoned for Industrial land uses. This analysis however, will focus on stationary noise sources that are ad)ecent to anNa near to sensitive land uses associated with the proposed General Plan and Zoning Code update. casinagraigimumgass Potential construction related noise impacts associated with proposed General Plan and Zoning Update and Redevelopment Plan will be Identified. The analysis wIN address short-term noise impacts associated with demolition, site preparation, grading and construction related to land uses associated with the proposed General Plan and Zoning Code update. Meals of Grmtadboume Vibration Impacts, Vibration impacts related to construction activities, stationary sources and mobile sources as they relate to General Plan and Zoning Code update land uses will be qualitatively addressed. Task 3. Noise Reduction Strategies Strategies for be reduction of City-wide noise impacts will be developed and presented in the Noise Report. These strategies are expected to include noise attenuation/reduction methods as well as noise Impact avoidance suggestions, utilizing design techniques. Task 4. Noise Impact Report Chambers Group will prepare a Noise Analysis that will: describe baseline conditions, outline current noise regulations and guidelines for mobile and stationary sources; Joyce Powers July 29, 2009 Page 7 identity potential impacts associated with implementation of the General Plan Update and Redevelopment Plan Amendment, and recommend strategies to reduce anticipated noise impacts. Chambers Group with respond to one set of comments from the City and with provide three hard copies and one electronic copy of the final study to the City.

Consultant will verity that the regional construction emissions analysis is consistent with the current project description and update as appropriate through utilizing the URBEMIS2007 Model. Consultant will verify that the local construction emissions analysis is consistent with the current project description and update as appropriate through utilizing the methodology described in Localized Significance Threshold Methodology, prepared by SCACMD, June 2003. Consultant will prepare a micro scale CO screening analysis of the study area Intersections based on the conditions in the Traffic Study prepared for the proposed project and verify if it is in accordance with the SCAOMD requirements as described in the CEQA Air Qualify Handbook Consultant will verify that the site operations mobile and stationary emissions analysis is consistent with the current project description and update as appropriate through utilizing the URBEMIS2007 Model. Task 2. Global Wring Analysis Consultant with review the prior Global Climate Change Analysis and identity the po[fons.. of the report that wiN need to be revised or completed. Consultant MN update the regulatory section to be consistent with the most current regulations. Consultant wiN update the thresholds of significance for greenhouse gases. Consultant will update the project compliance with existing regulations section. Joyce Powers July 29, 2009 Page 10 Consultant wIN evaluate the global warming potential associated with the construction activities for the proposed project utilizing the URBEMIS2007 Model. Consultant MN evaluate the greenhouse gases generated through the on-going operations of the proposed project and determine the proposed projects potential to create global climate change. Task 3.Ale Quality/Global Climate Change Report Consultant will prepare an Air Quality Impact Analysis and Global Climate Change Analysis describe baseline conditions, outline current air quality regulations and guidelines, identify potential Impacts associated with implementation of the General Plan Update and Redevelopment Plan Amendment, and recommend strategies to reduce air quality impacts. Consultant will respond to one set of comments from the City and will provide three herd copies and one electronic copy of the final study to the City.
