<br />EIP will evaluate noise levels from project and future traffic in the vicinity of the most severely <br />affected noise-sensitive receptors and the most heavily traveled roadways. The US Department <br />of Transportation's FHW A Highway Traffic Noise Prediction Model, initialized with <br />CAL VENa vehicular noise emission rates and site-specific traffic data, will be used to estimate <br />noise at affected sensitive receptors, including existing and potential residential uses. <br /> <br />Traffic noise levels will be analyzed for the same scenarios considered in the Traffic and <br />Circulation analysis. Where significant impacts are found, EIP will present feasible mitigation <br />measures, if possible. Such mitigation could include transportation control measures to orient <br />vehicle access so as to minimize impacts to the neighborhood or the potential medical center. <br />Other possible mitigation measures include sound barriers or baffles between project noise <br />sources and adjacent uses. <br /> <br />Task 4.4 Air Quality. The air quality setting will describe regional and local meteorological <br />conditions, ambient measurements from the nearest air monitoring station, and the policy and <br />regulatory framework. The EIR will include a discussion of the environmental setting describing <br />the non-attainment status of the Bay Area Air Basin (namely for criteria pollutants ozone and <br />particulate matter) and review available ambient air monitoring data for ozone, particulate matter <br />and carbon monoxide. The presence of region-wide toxic air contaminants will also be <br />reviewed, and the average health risks due to exposure to ambient concentrations of air toxics, <br />including particulate matter from diesel exhaust, will be identified using BAAQMD Toxic <br />Inventory Reports. Plans and programs in place to manage regional air quality will be <br />introduced. Measures in regional air quality plans that focus on providing pedestrian and transit <br />accessibility will be identified. The topography, wind patterns, and climate around San Leandro <br />will also be documented. <br /> <br />The impact analysis will include five basic components: <br /> <br />· Review of effects caused during construction phases (primarily dust generation and <br />secondarily construction equipment exhaust); <br /> <br />· Analysis of new emissions caused during occupation and use of the project (vehicular <br />and stationary sources, such as the boilers and generators in the Central Utility Plant <br />under the medical center alternative); <br /> <br />· Discussion of potential sources and effects of odors and toxic air contaminants; <br /> <br />· Analysis of local ambient CO impacts (if heavily congested traffic would occur); and <br /> <br />· Review of potential wind effects. <br /> <br />In all cases, the method of analysis and selection of significance thresholds will rely on <br />methodologies that are documented in the BAAQMD CEQA Guidelines, revised in 1999. <br /> <br />Estimates of the new motor vehicle emissions associated with project trips will be prepared using <br />the Air Resources Board's URBEMIS 2002 model. This model will provide a quantitative <br />assessment of project emissions from all motor vehicle trips generated by the project. The <br />results will be compared to the BAAQMD's quantitative thresholds for a significant impact. <br /> <br />Consulting Services Agreement between <br />City of San Leandro and ErP Associates <br /> <br />Page 30 of 43 <br />
