ENVIRONMENTAL IMPACT REPORT ADDENDUM Bristol Street Widening Phase IIIA — Civic Center Drive to Washington Avenue 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 Civic Center Drive to Washington Avenue (Phase IIIA, 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 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 Washington Avenue. However, using current noise modeling methodology (RBF Consulting 2014), noise abatement in the form of noise barriers is not required for the Phase IIIA Project. • For purposes of aesthetic treatment and enhancement, the proposed Project would install an approximately 8 -foot high block wall at approximately the same location where soundwalls were 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. • Addition of a westbound right -turn lane on Washington Avenue at Bristol Street. • Addition of a cul -de -sac at 9th Street on the west side of Bristol Street. • Full and partial acquisition on both sides of Bristol Street between Civic Center Drive and Washington Avenue. • Changes in land use as part of the Bristol Specific Plan Addendum, as follows: o Assessor Parcel Numbers (APNs) 405- 262 -21, -22, -23, -24, -25, -26, -27, -28,-29, -30, - 31, -32, and -33; and 405- 274 -09, -10,41, -12, and -13) —Land use change from Park to Park with Commercial option. Additionally, the topic of greenhouse gas (GFIG) emissions was not addressed in the previously approved 1990 FEIS /EIR as this topic was not a subject matter that required evaluation pursuant to CEQA at that time. As such, this Addendum analyzes the effects of GHG emissions associated with construction and operation of the proposed Project. ANA 305 -011 (PER 02) CITY OF SANTA ANA (01/19/2015) YU PAGE 1 75B -13
