Existing Traffic Data The existing intersection of Sarival Avenue/Peoria Avenue currently operates at an adequate level of service (LOS) during the weekday AM and PM peak hours. Future Traffic Data Without the Project The existing intersection of Sarival Avenue/Peoria Avenue is anticipated to continue operating at an adequate LOS in 2023 and 2026 during the weekday AM and PM peak hours without traffic from the project. Future Traffic Data With Project The shared eastbound through/right turn movement at the intersection of Sarival Avenue/Peoria Avenue is expected to operate at an inadequate LOS in 2026 with traffic from the project during the weekday AM peak hour. The delay is due to the limited capacity provided at the intersection and ALL-WAY STOP control becoming inefficient with the growing traffic volumes in the area, as each vehicle is required to stop and proceed through the intersection one at a time. The remaining study intersections are anticipated to operate at an acceptable LOS during the weekday AM and PM peak hours in 2023 and 2026 without and with traffic from the project. Turn Lane Analysis An eastbound right turn lane is proposed at the intersection of West Access/Peoria Avenue. The existing two-way center left turn lane on Sarival Avenue is expected to serve southbound left turning movements at North Access/Sarival Avenue and South Access/Sarival Avenue. Northbound right turn lanes are also proposed at North Access and South Access and required at Sarival Avenue/Peoria Avenue per City of Glendale direction. The proposed eastbound right turn lane at West Access is expected to serve a queue of 25 feet of storage. The proposed northbound right turn lane at North Access and South Access are expected to be free flow movements with minimal, if any, queue length. Revised Traffic Impact Analysis 3 Sarival Carioca — Sarival Avenue/Peoria Avenue Surprise Case File: P22-1467 — R= “a The required northbound right turn lane at the intersection of Sarival Avenue/Peoria Avenue is anticipated to need a queue of 25 feet of storage. No queue overlap is anticipated to occur between the project driveways and adjacent intersections. Crash Analysis There were seven (7) reported crashes (1 with injury) within the three-year study period at the intersection of Sarival Avenue/Peoria Avenue. The most common crash type was angle (57%) and single vehicle (29%) crashes. These types of crashes may be due to the intersection being in a undeveloped, relatively low volume traffic area, with vehicles not completing a full stop at the intersection prior to entering the intersection. Traffic Signal Warrant Analysis The intersection of Sarival Avenue/Peoria Avenue is expected to meet traffic signal warrants #1 and #2 in 2023 and 2026 with traffic from the project. Mitigation The shared eastbound through/right turn movement at the intersection of Sarival Avenue/Peoria Avenue is expected to operate at an inadequate LOS in 2026 with traffic from the project during the weekday AM peak hour. The delay is due to the limited capacity provided at the intersection and ALL-WAY STOP control becoming inefficient with the growing traffic volumes in the area, as each vehicle is required to stop and proceed through the intersection one at a time. This intersection is expected to be widened and signalized once the northwest and southwest corners of Sarival Avenue/Peoria Avenue are developed by future adjacent projects. Upon the construction of the future developments all approaches to the intersection of Sarival Avenue/Peoria Avenue are expected to be provided an exclusive left turn lane, two through lanes, and a dedicated right turn lane. These improvements are expected to alleviate the delay at the intersection. Recommendations The proposed eastbound right turn lane at West Access and northbound right turn lane at Sarival Avenue/Peoria Avenue, North Access, and South Access should be constructed with a minimum 160 feet of storage with 100 feet of taper to meet City of Surprise and City of Glendale minimum requirements.
