ENVIRONMENTAL IMPACT REPORT ADDENDUM Bristol Street Widening Phase IIIA — Civic Center Drive to Washington Avenue 9.4.3 Changes as Compared to the Approved Project It should be noted that Project phasing has been revised from the original three phases identified in the 1990 FEIS/EIR. Construction phasing of the entire Project segment has been further subdivided as follows: • St. Andrew Place to McFadden Avenue (Constructed in 2002) • Elm Street to Memory Lane (Constructed in 2003) • Pine Street to 3rd Street (Constructed in 2009) • Phase I: McFadden Avenue to Pine Street (Constructed in 2011)1 • Phase II: 3rd Street to Civic Center Drive (Constructed in 2014) • Phase IIIA: Civic Center Drive to Washington Avenue • Phase IIIB: Washington Avenue to 17d' Street • Phase IV: Warner Avenue to St. Andrew Place • Phase V: 171h Street to Elm Street The proposed street widening design configuration for the current Phase IIIA segment (proposed Project addressed herein) differs from the original configuration of the 1990 FEIS/EIR, as follows: • 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 FEISIEIR. However, the proposed Project right-of-way cross section, as compared to the right-of-way cross section addressed in the 1990 FEISIEIR, 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 FEISIEIR. 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. • Removal of eastbound through movement on Washington Avenue at Bristol Street to match existing condition. • 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: '- Phase numbers were assigned to the Bristol Street Widening Project subsequent to cancelation of the CcnterLine Light Roil Transit Project and associated reallocation of funding from that canceled project to the Bristol Street Widening Project, ANA 305-011 (PER 02) CITY OF SANTA ANA (01/19/2015) YU PAGE 17
