NT MENTS INITIAL STUDY/MITIGATED NEGATIVE DECLARATION FAIRVIEW BPIOGE REVLACEM REST TO STREET BEET) PROJECT L S A MAY 2020 (9Tx STREET To ANTx STREET) L, OLEGT SANTA ANAL CALIFOPHIA increase VMT in the area, which could increase criteria pollutant emissions. On the other hand, the improved bridge may attract additional pedestrians and bicyclists due to added sidewalks and bikeways, which would have the potential to reduce vehicle trips and increase the use of alternate means of transportation. Therefore, the Project would not result in a significant increase in the generation of vehicle trips that would increase criteria pollutant emissions. The proposed Project would result in low levels of off -site emissions due to energy generation associated with lighting along the roadway segment and the Fairview Street bridge. However, these emissions would be minimal and would not exceed the pollutant thresholds established by the SCAQMD. In addition, the Project's Traffic Impact Analysis (TIA; Appendix A) shows that the intersections of Fairview Street/17th Street and Fairview Street/9th Street operate at unsatisfactory level of service (LOS) E or worse during one or both peak hours in existing conditions. The unsatisfactory LOS (average vehicle delay at intersections in the Project area) cause more idling emissions to occur. The proposed widening of Fairview Street from four through lanes to six through lanes between 9th Street and 16th Street would accommodate future traffic volumes with satisfactory LOS. The increase in traffic capacity would increase average vehicle speeds and reduce the average vehicle delay during peak -hour traffic, both of which would reduce the rate of vehicle emissions. Therefore, the proposed Project would result in a beneficial impact to regional and local air quality. As a result, Project operation would not result in a cumulatively considerable net increase of any criteria pollutant for which the Project region is nonattainment under an applicable federal or State ambient air quality standard, and no mitigation is required. c. Would the project expose sensitive receptors to substantial pollutant concentrations? Less Than Significant with Mitigation Incorporated. Sensitive receptors are defined as people that have an increased sensitivity to air pollution or environmental contaminants. Sensitive receptor locations include schools, parks and playgrounds, day care centers, nursing homes, hospitals, and residential dwelling units. The closest sensitive receptors include the single-family and multifamily residences located adjacent to Fairview Street. In addition, the REACH Academy Community Day Intermediate and High School is located adjacent to the southern border of the Project site. Construction of the proposed Project may expose these surrounding sensitive receptors to airborne particulates and fugitive dust, as well as a small quantity of construction equipment pollutants (i.e., usually diesel -fueled vehicles and equipment). The Construction Contractor would be required to minimize emissions by following standard construction practices and complying with SCAQMD rules (i.e., Rules 402 and 403). Rule 402 requires implementation of dust suppression techniques to prevent fugitive dust from creating a nuisance off -site. Rule 403 requires that fugitive dust be controlled with best available control measures so that the presence of such dust does not remain visible in the atmosphere beyond the property line of the emission source. As described in Response 3.3.2(b), additional construction emissions reduction methods would be implemented as specified in Mitigation Measure AQ-1. With implementation of Mitigation Measure AQ-1, sensitive receptors would not be exposed to substantial pollutant concentrations during construction.
