ENVIRONMENTAL IMPAOTREPORTADDENDUM Bristol Street Widening Phase IIIB— Washington Avenue to 17" Street 1.0 INTRODUCTION This Addendum has been prepared in accordance with the California Environmental Quality Act (CEQA), as amended, to evaluate the potential environmental impacts of the proposed changes to the widening of Bristol Street, from Warner Avenue to Memory Lane as proposed in the Project Final Environmental Impact Statement / Environmental Impact Report (FEIS /EIR) approved in 1990 (FHWA-CA- EIS- 89 -01- F; SCH No. 87071509). This Addendum focuses on the segment of Bristol Street between Washington Avenue and 17 °i Street (Phase IIIB, or Project) and is limited to the proposed improvements to this segment. This Addendum provides an assessment of potential environmental impacts associated with minor design modifications and the issue of climate change which was not addressed in the previously prepared and certified FEIS /EIR. Design modifications to the Project, since approval of the 1990 FEIS /EIR, that are addressed in this Addendum include the following: • The proposed Project eliminates the dedicated eastbound right -turn lane and proposes a shared right -turn lane in its place at the intersection of Bristol Street and 176' Street. • The 1990 FEIS /EIR, using decommissioned noise methodology, recommended noise barriers (soundwalls) at all easterly parcel boundaries currently fronting the east side of Bristol Street between Civic Center Drive and 1701 Street. However, using current noise modeling methodology (Noise Study Report, URS Corporation 2012c), noise abatement in the form of noise barriers is not required for the Phase IIIB Project. • For proposes of aesthetic treatment and enhancement, the proposed Project would install an approximately 8 -foot high block wall at approximately the same location where the soundwall was previously recommended (as addressed in the 1990 FEIS /EIR). • The proposed Project increases the total right -of -way width from 120 feet to 128 feet. The proposed Project right -of -way cross - section would maintain a curb -to -curb width of 100 feet, would accommodate a 7 -foot wide bike lane on each side of the roadway, and would not affect the number or width of vehicular travel lanes as compared to the right -of -way cross - section addressed in the 1990 FEIS /EIR. However, the proposed Project right -of -way cross section, as compared to the right -of -way cross section addressed in the 1990 FEIS /EIR, would reduce the width of the sidewalks from 10 to 8 feet and also accommodate a 6 -foot wide parkway on each side of Bristol Street to separate pedestrian and vehicular travel; a parkway was not included as part of the roadway cross section addressed in the 1990 FEIS /EIR. Acquisition of property resulting from the proposed Project right-of-way is accounted for in this analysis. Additionally, the topic of greenhouse gas (GHG) emissions was not addressed in the previously approved 1990 FEIS /EIR as this topic was not IF subject matter that required evaluation pursuant to CEQA at that ANA 111 -334 (PER- 02 -01) CITY OF SANTA ANA (01/30/2014 REV3) 132897 CM PAGE I 55A -10
