ENVIRONMENTAL IMPACT REPORT ADDENDUM <br />Bristol Street Widening Phase tiiA — Civic Center Drive to Washington Avenue <br />Southeast Receptor 6.6 20 4,5 9.0 No No <br />Southwest Receptor 6.7 20 4,5 9.0 No No <br />Northwest Receptor 6.7 20 4.5 9.0 No No <br />Source: Air Quality Assessment Report (Jl 2013a). <br />Note: CAAQS = Callforria Ambient Air Quality Standards. <br />As discussed previously, the proposed Project would not result in air pollutant concentrations that exceed <br />the SCAQMD's LSTs for construction activities. In addition, the operations phase of the Project would <br />not result in CO hotspots. As such, the construction and operations phases of the Project would not result <br />in significant impacts to air quality which would expose sensitive receptors to substantial air pollutant <br />concentrations. <br />Mitigation Measures <br />No additional new mitigation measures are required. <br />e.) Create objectionable odors affecting a substantial number ofpeople? <br />Construction activities associated with the proposed Project may generate detectable odors from heavy- <br />duty construction equipment and exhaust. Odors associated with diesel and gasoline fumes are transitory <br />in nature and would not create objectionable odors affecting a substantial number of people. The impacts <br />from these odors would be short-term, would cease upon Project completion, and are not anticipated to be <br />significant. Implementation of the proposed Project would not result in greater impacts than previously <br />analyzed in the 1990 FEIS/EIR. <br />Mitigation Measures <br />No additional new mitigation measures are required. <br />3.4 Biological Resources <br />This section corresponds with Section IV - Environmental Consequences and Mitigation Measures, <br />Subsection E - Streambed Modification, of the previously approved 1990 FEIS/EIR. <br />a.) Have a substantial adverse effect, either directly or through habitat modifications, on any species <br />identified as a candidate, sensitive, or special -status species in local or regional plans, policies, or <br />regulations, or by the California Department of Fish and Game or US Fish and Wildlife Service? <br />The Project site is located within a highly urbanized area within the City of Santa Ana. No sensitive <br />natural habitat or special -status species exist on or in the vicinity of the proposed Project (Natural <br />Environment Study [Minimal Impacts], URS Corporation, April 2011). Implementation of the proposed <br />Project would not result in greater impacts than previously analyzed in the 1990 FEIS/EIR. <br />Mitigation Measures <br />No new additional mitigation measures are required. <br />b.) Have a substantial adverse effect on any riparian habitat or other sensitive natural community <br />identified in local or regional plans, policies, or regulations or by the California Department of <br />Fish and Game or US Fish and Wildlife Service? <br />ANA 305-011 (PER 02) CITY Or SANTA ANA (OV19/2015) YU PAGE 35 <br />
