URS will conduct traffic noise modeling related to the proposed project using the FHWA Traffic Noise Model (I Iv 1V1) Version 2.5 and traffic data to be provided by the project traffic engineer. TNM will be used to model highest noise hour conditions at representative modeled receiver locations under existing conditions and design year conditions with and without the proposed project. Traffic noise impacts of the proposed project under 23 CFR 772 will be assessed by determining if implementation of the project is projected to result in traffic noise levels under design year conditions that approach or exceed the FHWA noise abatement criteria, or if implementation of the project is predicted to result in a substantial increase in noise at noise - sensitive uses. A Noise Study Report will be prepared in accordance with reporting guidelines set forth at Caltrans' SER, Volume 1 (General), Chapter 12 (Noise). URS will also evaluate potential construction noise impacts using methods recommended by the U.S. Department of Transportation. Given the findings of the analyses performed as part of the 1990 Final EIS/EIR, it is assumed that noise impacts will occur at sensitive receivers and abatement will be deemed acoustically feasible. Therefore, a Caltrans-compliant Noise Abatement Decision Report to address the reasonableness of noise abatement as defined in Caltrans' Traffic Noise Analysis Protocol (2006). Traffic Impact Analysis A Traffic Impact Analysis will be conducted and prepared to meet City and Caltrans' requirements. The Traffic Impact Analysis will evaluate the project for consistency with the City's General Plan Circulation Element, City's Master Plan of Bikeways, Orange County Transportation Authority Master Plan of Arterial Street and Highways, and SCAG's Regional Comprehensive Plan and Regional Mobility Element. Project alternative impacts will also be evaluated with respect to on -street parking and during the construction of the street widening improvements. Initially, a field review will be conducted to document the existing features of the affected roadway segment and key study intersections within the limits of the project. URS also will review available traffic count data from the City to determine if any recent counts have been conducted within the study area. New traffic counts will be collected as needed to supplement older or missing traffic data. It is assumed that all relevant and applicable cumulative projects will be identified and will be provided by City staff. Finally, URS will collect all applicable approved improvements at the study roadway segment and intersections that will by implemented within the traffic analysis scenarios (i.e., existing and future analyses). The traffic analysis will evaluate up to four roadway segments and six study intersections as follows: ■ Phase 3 includes the following study intersections: - Bristol Street/Civic Center Drive - Bristol Street/Washington Avenue - Bristol Street/17th Street ■ Phase 4 includes the following study intersections: - Bristol Street/Warner Avenue - Bristol Street/Glenwood Place - Bristol Street/Saint Andrew Place 11
