3. Santa Rita Road at Vallev Avenue widenine for triple southbound and double westbound left turns: Yote: 4-1 Yes: Commissioners, Blanc Fox, Olson, and Pearce. No: Commissioner Arkin. 4. Santa Rita Road at Black Avenue - nrohibit traffic from exitine the Santa Rita frontage road onnosite Black Avenue. Reroute this traffic to the new sienal at Francisco Street. Eliminate the north crosswalk at the intersection. Commissioner Pearce requested Mr. Tassano to clarify this item before the Commission took a vote. Mr. Tassano explained that the modeling is based on the anticipation that the level of service at Santa Rita Road and Black Avenue would begin to fail in the peak hours due to the inability of the east-west left-turn movements to go simultaneously, which results in the number of left turns coming out of the school and the post office going towards Santa Rita Road becoming too great to keep the levels of service at acceptable levels. He added that a possible mitigation to improve that level of service would be to prohibit those left turns and move that entire movement up to Francisco Street, which would be signalized for pedestrian safety. Commissioner Fox inquired why this was not included in the 1996 General Plan intersection improvements. Mr. Tassano replied that this would be a modification in looking at how travel patterns have changed since the 1996 General Plan and what new improvements aze necessazy to maintain the level of service. Commissioner Fox commented that someone who picks up a student from Alisal School and then heads south to Pleasanton Middle School would not be able to exit on Santa Rita Road at Black Avenue but would have to take the side street up to Francisco Street, where they will need to turn left to go back through the Black Avenue/Santa Rita Road intersection and head south to Pleasanton Middle School. Mr. Tassano clarified that anyone who wanted to go south from Alisal School would not have to go out on Francisco Street but would just have to turn left out of the driveway and go south on the frontage road and come out on Silver Street near Amador High School. He stated that a better example would be someone who wanted to go across to Black Avenue from Alisal School would need to go up to Francisco Street, then make a U-Turn and turn right on Black Avenue. Commissioner Fox noted that there is no pick-up and drop-off from the back side of Alisal School because of Valley Business Park. She added that students coming from ~ Busch Avenue would have to go to Santa Rita Road because Ko11n Street is blocked on Valley Avenue. Mr. Tassano confirmed Commissioner Fox's observation.
