CITY OF SANTA ANA 2 PROJECT DESCRIPTION AND BACKGROUND The First Street Multimodal Boulevard project aims to transform and improve the First Street corridor for all modes of transportation, including bus, bicycles, and pedestrians with enhanced access to businesses, residential neighborhoods, educational facilities, and other key destinations. The project area includes 16 signalized intersections, owned and operated by City of Santa Ana, along the nearly 3- mile section of First Street from Bristol Street to Tustin Avenue. The intersections are listed in Table 1 below: Table 1: Project Intersection No. Intersection No. Intersection 1 First Street and Bristol Street 9 First Street and Standard Avenue 2 First Street and Flower Street 10 First Street and Grand Avenue 3 First Street and Ross Street 11 First Street and Lyon Street 4 First Street and Broadway Street 12 First Street and Elk Ln I-5 NB 5 First Street and Sycamore Street 13 First Street and I-5 SB on ramp 6 First Street and Main Street 14 First Street and Cabrillo Park Drive 7 First Street and Bush Street 15 First Street and Golden Circle 8 First Street and Downtown Plaza 16 First Street and Tustin Avenue First Street is currently a 6-lane roadway divided by a raised median with left turn pockets. Per the Mobility Element of City’s General Plan (updated April 2022), First Street between Bristol Street and Tustin Avenue will be reclassified from a major (6-lane, divided) arterial to a primary (4-lane, divided) arterial. The buildout cross-section exists today for most of the corridor, with the exception of a constrained rail undercrossing between Standard Avenue and Grand Avenue. The General Plan update envisions the repurposing of the outer curbside lanes to serve active transportation and transit uses, reducing vehicle capacity between Bristol Street and Tustin Avenue (approximately three miles). OCTA’s Route 64 bus line runs from Huntington Beach to Tustin primarily along Bolsa Avenue and First Street. Route 64Xpress (Route 64x), a limited stop service along the same route, was suspended during the pandemic. Routes 64 and 64x generally operate at 30-minute intervals. At Route 64Xpress stops, the combined frequency is every 15-minutes. The route consists of approximately 90 stops covering both directions with over half of them in Santa Ana.
