Bernal Avenue at Vineyard Avenue (N) Mitigation - Widen Bernal Avenue to 4 lanes including Arroyo Del Valle Bridge The 1996 General Plan includes the widening of Bemal Avenue to 4 lanes north of Angela Street. This includes Bemal Avenue north and south of this intersection. Widening the bridge over Arroyo Del Valle will provide increased southbound left turn capacity from Bemal Avenue to Vineyard Avenue. It will also allow the traffic signal at the intersection to be upgraded to a far more efficient operation. These changes will significantly reduce congestion and delay at the intersection for Pleasanton residents. However it will also likely facilitate an increase in traffic along the Vineyard Corridor. E1 Charro Road at Busch Road Mitigation - Widen both E1 Charro Road and Busch Road into 4-lane divided roadways The 1996 General Plan includes the widening of Busch Road and El Charro Road as 4-lane divided roadways. The Year 2025 scenarios that include some of the 1996 General Plan road widenings assume that both of these roadways are 4-lane divided roads. First Street at Kottinger Drive / Spring Street Mitigation - Make Spring Street one-way westbound between First Street and Railroad Street. Constructing a traffic signal at this intersection has resulted in significant increases in traffic volumes along Spring Street and Kottinger Drive resulting in severe LOS F conditions at this intersection. The smooth flow of traffic along First Street helps to improve Transit service time, improved emergency vehicle access, and reduces traffic volumes along Second Street. The Year 2025 scenarios studied assume that First Street remains a 3-lane road, with Spring Street being made one-way westbound between First Street and Railroad Street. This reduces traffic along the narrowest section of Spring Street and reduces congestion and delay at First Street by eliminating the eastbound approach to the intersection. This change would have no impact on pedestrian circulation at the intersection, and would increase pedestrian safety by eliminating eastbound left tums over the north crosswalk. First Street at Ray Street / Vineyard Avenue Mitigation - Upgrade the traffic signal to provide protected/permissive left turn arrows. The existing signal operations for Vineyard Avenue and Ray Street are very inefficient and reduce green time along First Street. East and westbound traffic moves separately, with each direction timed long enough for pedestrians to cross First Street. By providing left turn arrows for both directions and allowing east/west through traffic and pedestrians to cross concurrently, more green time will be available for residents on First Street traveling through, or making left tmns at the intersection. Foothill Road at Canyon Way / Dublin Canyon Road Mitigation - Restripe and upgrade traffic signal to provide triple southbound and eastbound left turn lanes Double left turn lanes are recommended when left turn traffic volumes reach 300 vehicles per hour. The southbound left turn at this intersection is forecast to reach over 700 vehicles per hour in the morning as drivers try to access the Mall, BART and all of the offices in the Mall area. Restriping and reconfiguring the traffic signal to convert the #1 southbound through lane into a third left turn lane significantly reduces left turn delay and queuing, while still providing LOS C conditions for southbound through traffic. Canyon Way will need to be widened to accept traffic from three left turn lanes. 4
