ENVIRONMENTAL IMPACT REPORTADDENDUM Bristol Street Widening Project Warner Ave to Saint Andrew Place (Phase IV) 1985. Furthermore, the proposed project would result in an improvement to the Bristol Street at Warner Avenue, Glenwood Place, and Saint Andrew Place intersections. Impacts would be similar to those identified in the 1990 Final EIS/EIR. Mitigation Measures No new additional mitigation measures are required. (b) Conflict with an applicable congestion management program, including, but not limited to level of service standards and travel demand measures, or other standards established by the county congestion management agency for designated roads or highways? The proposed project would result in an improvement to Bristol Street from Warner Avenue to Saint Andrew Place. Once the project has been implemented, all roadway segments would operate at LOS D or better. 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 Final EIS /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 approximately 3.5 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 Final EIS /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 Warner Avenue to Saint Andrew Place 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 Final EIS /EIR. Mitigation Measures No new additional mitigation measures are required. (e) Result in inadequate emergency access? The proposed project would improve traffic flow along Bristol Street in the long -term. However, during the construction phase, the disruption of traffic and restricted access along Bristol Street could temporarily affect the mobility of emergency vehicles. Provisions would be made for interim access, and traffic control plans would be prepared prior to construction. Additionally, advance warning and information signs would be used to reduce the confusion motorists may experience during the construction process. Bristol Street would remain open during construction. Although the proposed project may interfere with emergency access in the short -tern, it would improve emergency access once the project is completed. The proposed project would not result in a more significant impact to emergency access than previously analyzed, and with the implementation of mitigation measures as prescribed in the 1990 Final EIS/EIR.
