ENVIRONMENTAL IMPACT REPORT ADDENDUM Bristol Street Widening Project Warner Ave to Saint Andrew Place (Phase IV) unidentified mineral resources. No impact to mineral resources would result from the proposed project. hnpacts would be similar to those identified in the 1990 Final EIS/EIR. Mitigation Measures No new additional mitigation measures are required. (b) Result in the loss of availability of a locally - important mineral resource recovery site delineated on a local general plan, specific plan or other land use plan? The project site is currently developed and is not delineated as a mineral resources recovery site by the City of Santa Ana General Plan. Implementation of the proposed project would have no impact on the mineral resources and no mitigation measures are necessary. Impacts would be similar to those identified in the 1990 Final EIS/EIR. Mitigation Measures No new additional mitigation measures are required. 3.12 Noise This section corresponds with Section IV, Environmental Consequences and Mitigation Measures, Subsection I, Noise, and V, Construction Impacts of the 1990 Final EIS /EIR. (a) Exposure of persons to or generation of noise levels in excess of standards established in the local general plan or noise ordinance, or applicable standards of other agencies? The proposed project involves widening of Bristol Street between Warner Avenue and Saint Andrew Place. The land uses in between Warner Avenue and St. Gertrude Place, and adjacent to the project, are commercial (Category C) on the west side of Bristol Street, and a mix of residential and commercial land uses on the east side of Bristol Street. The land uses on both sides of Bristol Street between St. Gertrude and St. Andrew Place are residential. Mater Dei High School is located along the east side of Bristol Street north of St. Andrew Place. Jose Andres Sepulveda Elementary School is west of Bristol Street in this same area. The future noise modeling results of the 1990 Final EIS /EIR indicated that future noise levels would be no more than one dBA higher with the project as compared to levels without project improvements (noise level changes of less than 3 dBA are normally inaudible to the human ear). The 1990 Final EIS /EIR (and 2013 NEPA Reevaluation) provided comprehensive noise barriers at all easterly parcel boundaries currently fronting the east side of Bristol Street between Warner Avenue and Saint Andrew Place and comprehensive noise barriers at all westerly parcel boundaries currently fronting the west side of Bristol Street between West Saint Gertrude Place and Saint Andrew Place. The following noise barriers were determined to be reasonable: NB -4, NB -5, NB -6, NB -7, NB -8, NB -9, NB -10, and NB -11. These noise barriers are generally equivalent to the recommended noise barriers shown in the 1990 FEIS and 2013 Reevaluation. However, barriers NB -6, NB -7, NB -8, and NB -9 would need to be shifted to the west of the receivers (parcels) that are no longer being acquired in whole such that these barriers are now proposed at the westerly parcel boundaries that front the east side of Bristol Street between Saint Anne Place and Saint Andrew Place (refer to Figure 7a and Figure 7b). Furthermore, the reasonable noise barriers would be constructed at a height of 8 feet, as opposed to 6 feet as identified in the 1990 FEIS and 2013 NEPA Reevaluation. The modifications and other refinements to the project would not create any additional impacts than what was identified in the 1990 Final EIS/EIR. With implementation of the mitigation measures from the 1990 Final EIS /EIR, noise impacts would be similar to that identified in the 1990 Final EIS /EIR.
