Proposal for San Lorenzo Lift Station EIR Prepared for: CITY OF SANTA ANA EXHIBIT B: SCOPE OF WORK 6. Compare the predicted noise levels during the construction phases with the applicable City of Santa Ana exterior noise level requirements. Identify locations that will exceed applicable exterior noise standards and predict the noise level increase during construction over current ambient noise levels with and without recommended mitigation measures. 7. Recommend temporary noise barrier locations and heights and identify noise mitigation measures to reduce the noise impacts during the construction phase and meet the City of Santa Ana Noise Standards. 8. Summarize the results of the study in a report addressing the construction noise impacts and recommended mitigation measures. 9. The scope of work includes necessary teleconferences with the project team, attendance at up to one (1) project team meeting, and a review of project team comments and minor revisions required to the noise analysis report for up to one review cycle. Task 3.4 - Air Quality Impact & Climate Change Analysis In order to assess the project's potential to create air emissions during construction activities that exceed established significance thresholds, and to conduct a brief analysis of potential odor impacts that may result from long -term operation of the proposed facility, Urban Crossroads, Inc. will prepare an air quality impact analysis for the project. In addition, and in response to on -going concerns over the issue of Global Climate Change, an analysis also will be conducted to evaluate the State of California Global Climate Change Solutions Act of 2006 (AB 32) in order to identify any mitigation measures that may be necessary during construction to ensure compliance with the Act. The cost estimates for the air quality and climate change analyses assumes that the City will provide complete and comprehensive data regarding project construction and operations. Data include, but are not limited to: construction schedule (including all phases of demolition, site preparation, excavation, building, etc.); construction equipment fleet information; yards of soil to be excavated, hauled, or imported; and manufacturer's specifications of any new equipment installed. Additionally, the cost estimates for climate change analysis assumes evaluation under current (January 2010) regulations. Because regulations related to climate change at the federal, state, and regional levels are subject to frequent change in California, the consultants reserve the right to request additional data and fees to complete additional analyses, if any, that may be required for analysis of conformance with any new climate change regulations that may be adopted after January 2010 but prior to the Final EIR being certified by the City. As part of this task, Urban Crossroads shall undertake the following work efforts: 1. Review aerial photos and maps to identify the air quality sensitive locations in the study area that may be significantly impacted by construction emissions and review the City of Santa Ana construction air quality standards. 2. Evaluate the existing conditions of the project study area; this will include gathering background air quality data, local wind patterns in the study area and identifying applicable rules, plans and thresholds of significance.
