3. Lengthen the eastbound Dublin Canyon Road left-turn lane next to the median by narrowing the existing 18-foot wide median. No additional right-of-way is required. The purpose of this improvement is to more fully utilize all left-turn lanes by reducing the possibility of one lane being blocked. Green time at the traffic signal will be reduced for this movement by creating a more even distribution of traffic across the left-turn lanes. B. StoneridGe Drive/Stonerid~e Mall Road 1. Restripe one of the through lanes on westbound Stoneridge Drive to create an optional through and right-turn lane. The curb return on the northeast corner should be modified to facilitate this maneuver. This will require right-of-way acquisition. The purpose of this improvement is to shorten the queue for westbound traffic turning right into the Stoneridge Mall area and thereby reduce the amount of green time required. The westbound right turn is a critical movement during the a.m. and p.m. peak hours. It is expected that right turning vehicles will dominate this lane. The need for one additional westbound lane was evaluated and determined to be unnecessary based on no change in the volume-to-capacity ratio. 2. Restripe the southbound Stoneridge Mall Road right-turn lane to provide an optional right- turn and left-turn lane at this "T" intersection. This will spread the critical southbound left-turn movement over three lanes instead of two lanes, thereby reducing the amount of green time necessary to clear the queue. In addition, there is a need to retrofit the signal controller to include an emergency vehicle preemption capability since a City of Pleasanton Fire Station is located nearby. Page 2 of 3
