FN City of Santa Ana I First Street Multimodal Corridor <br /> Technical Memorandum <br /> Traffic Operations <br /> First Street is currently a six-lane divided roadway with a raised median and dedicated turn <br /> pockets at intersections. The road has a capacity of 56,300 vehicles per day at LOS E. The <br /> threshold for acceptable level of service (LOS D) is 50,600 vehicles per day. Within the study <br /> area there are 16 signalized intersections and several unsignalized intersections. The posted <br /> speed limit is 40 miles per hour (mph) despite the presence of several school and senior <br /> facilities within the study area. <br /> To assess the existing traffic conditions along the corridor, peak hour intersection volumes <br /> (vehicles, pedestrians and bicycles)and daily volumes (speed, volume and classification) <br /> were collected at locations along the corridor during a typical weekday in March 2025. <br /> Daily Volume Analysis <br /> Daily traffic volumes were collected at eight spot locations along the corridor. Table 2 below <br /> summarizes the volume and the existing level of service based on the City's level of service <br /> thresholds for roadway segments. <br /> Table 2. Existing Roadway Segment Level of Service <br /> D. . . <br /> Baker Street to Shelton Street 20,526 18,862 39,388 B <br /> Parton Street to Ross Street 21,155 19,046 40,201 C <br /> West of Spurgeon Street 20,773 16,490 37,263 B <br /> East of Garfield Street 18,417 15,626 34,043 B <br /> Standard Avenue to Grand Avenue 18,373 14,924 33,297 A <br /> West of Wright Street 18,476 15,598 34,074 B <br /> West of Cabrillo Park Drive 14,451 10,603 25,054 A <br /> Golden Circle Drive to Tustin Avenue 10,373 8,766 19,139 A <br /> As shown, all of the segments currently operate at LOS C or better. To understand the <br /> peaking characteristics along the corridor, the daily volumes at the locations with highest <br /> volume (Parton Street to Ross Street) and lowest volume (Golden Circle Drive to Tustin <br /> Avenue) were evaluated on an hourly basis. Figure 6 illustrates the volumes over a 24-hour <br /> period, which shows at both the highest and lowest volume locations there are similar <br /> peaking characteristics, which occur in the AM (7:00 to 9:OOAM) and in the PM (3:30 — <br /> 5:30PM). <br /> 13 <br />
