TRAFFIC IMPACT ANALYSIS FAIRVIEW STREET IMPROVEMENTS FROM 9T" STREET TO 16T" STREET AND /\ JUNE 2018 BRIDGE REPLACEMENT PROJECT J" SANTA ANA, CALIFORNIA INTRODUCTION This Traffic Impact Analysis (TIA) has been prepared to assess the effects of the Fairview Street Improvements from 9th Street to 161h Street and Bridge Replacement Project (project) on intersection and roadway performance. The project proposes to widen the Fairview Street crossing over the Santa Ana River (SAR) from four lanes (two lanes in each direction) to six lanes (three lanes in each direction) between the intersections of 9th Street and 16th Street in Santa Ana, California. This segment of Fairview Street includes a bridge (Fairview Street bridge) over the SAR. LSA performed this TIA consistent with relevant guidelines from the City of Santa Ana (City) Circulation Element and Capacity Calculations and Level of Service Standards. The purpose of this TIA is to document how Fairview Street, between Civic Center Drive and 171h Street, would function without and with the project in the future. The study area comprises the following intersections: 1. Fairview Street/171h Street 2. Fairview Street/161h Street 3. Fairview Street/121h Street 4. Fairview Street/9th Street 5. Fairview Street/Civic Center Drive This report analyzes roadway segments of Fairview Street between Civic Center Drive and 17th Street; specifically, the segments between each of the study intersections. Figure 1 shows the project area. Existing Facilities The City's Circulation Element and the Orange County Transportation Authority Master Plan of Arterial Highways (MPAH) identify Fairview Street between Civic Center Drive and 17th Street (over the SAR) as a six -lane, divided Major Arterial. The bridge currently provides two lanes in each direction. The segment of Fairview Street to the north of 16th Street currently provides two lanes in each direction, with the exception of a three lane southbound segment between Avalon Avenue and Bolivar Circle. Fairview Street south of 9th Street currently provides three lanes in each direction. Fairview Street has a posted speed limit of 45 miles per hour on segments north and south of the bridge. Sidewalks exist on both sides of Fairview Street, with the exception of the segment on the bridge. Bicycle facilities, such as bicycle lanes, do not exist on Fairview Street; however, the Santa Ana River Trail that runs along the SAR's eastern bank has access points to both the northbound and the southbound sides of Fairview Street at the southern end of the bridge. The trail on the SAR's western bank does not have direct connections to Fairview Street. Figure 2 illustrates the roadway geometrics of the intersections within the study area. Project Description Implementation of the MPAH would widen Fairview Street bridge to accommodate three lanes in each direction. The project would also provide additional facilities, such as 8-foot-wide sidewalks PAWKE1702\Traffic\doc\Traffic Analysis Report rev - Caltrans Comments.docx u06/07/18»
