ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Phase IIIB — Washington Avenue to 17`" Street The proposed Project would result in an improvement to Bristol Street from Washington Avenue to 17r' Street. Within the Project limits, Bristol Street would be widened from four to six lanes. 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; elimination of this right -turn lane would not result in a reduction in level of service as evaluated in the 1990 FEIS/EIR. The Project would result in improved traffic flow and LOS along the roadway; therefore, the proposed Project would not cause the County congestion agency's LOS standards to be exceeded. Impacts would be similar to those identified in the 1990 FEIS /EIR. Mitigation Measures No new additional mitigation measures are required. c.) Result in a change in air traffic patterns, including either an increase in traffic levels or a change in location that results in substantial safety risks? The closest airport to the site is John Wayne — Orange County Airport, located more than five miles southeast of the Project site; the proposed Project would have no impact on air traffic patterns. The proposed Project would not introduce any new risks or increase risks. Impacts would be similar to those identified in the 1990 FEIS /EIR. Mitigation Measures No new additional mitigation measures are required d.) Substantially increase hazards due to a design feature (e.g., sharp curves or dangerous intersections) or incompatible uses (e.g., farm equipment)? The proposed Project would improve the traffic flow along Bristol Street from Washington Avenue to 17t1i Street, and would not create any sharp curves or other incompatible uses. The proposed Project would not create any significant hazards beyond what was previously analyzed. Impacts would be similar to those identified in the 1990 FEIS/EIR. Mitigation Measures No new additional mitigation measures are required. e.) Result in inadequate emergency access? The proposed Project would improve traffic operations along Bristol Street in the long -term. During the construction phase traffic flow along Bristol Street within the Project limits could be temporarily affected, including the mobility of emergency vehicles; however, access, including two -way travel would be maintained through the Project corridor during construction. Traffic control plans would be prepared prior to construction to facilitate traffic movement through the Project corridor during construction.
