Ito —V If, Vl%v YYlll utilize traffic data from the technical traffic report prepared for this project as Input parameters into the URBEMIS 2007 model to estimate mobile emissions. Total construction and operational emissions would then be compared to the SCAQMD regional thresholds of significance. if the analysis shows that there would be significant air quality impacts, feasible and applicable mitigation measures would be recommended to reduce air quality impacts to a level considered less than significant or to the maximum extent possible. Upon completion of the air quality model runs, URS will prepare a draft Technical Memorandum summarizing the methods/data used, and results with the URBEMIS model runs and calculations. The Technical Memorandum will be Included as an appendix to the project's environmental documentation. ➢ Noise The URS Acoustics and Noise Control Group will assess the existing and future land uses on and surrounding the project site using the most recent land use mapping provided by the City for the proposed project. Using existing noise measurement data from recent surveys, the change in the projected noise exposure level due to the expected change in project related traffic will be calculated, and any impacts to noise sensitive land uses in the project area associated with those noise level increases will be Identified. The URS Acoustics and Noise Control Group staff will address issues that arlse regarding environmental and project related noise and acoustical concerns. Relevant sections of the Bristol Street Specific Plan will be updated and revised as required. ➢ Recreation Similar to Aesthetics noted above, benefits were identified to the quantity and quality of City recreational resources as a result of the park designated land uses of the Specific Plan. The change to commercial use will Impact the previous analysis, therefore a new assessment with respect to recreational uses will be prepared and incorporated In the environmental analysis for the SPA. ➢ Traffic Traffic will be the resource that will potentially be the most significantly impacted as daily trip generation associated with proposed commercial uses will be considerably more than those associated with Open Space/Park uses. A detailed Traffic Analysis, therefore, is recommended and will be prepared to assess trip generation and analyze potential impacts. Specific tasks associated with the Traffic Analysis are as follows:
