Mr. Tassano said yes. He stated that staff annually monitors all City - signalized or future signalized locations and all the locations where there has been excessive delay. He explained that these are then ranked and prioritized to determine if they do need a traffic signal. He indicated that there are currently 17 locations that have been written into the General Plan for a future traffic signal. Commissioner Pearce inquired if staff would go out and visit locations that residents have concerns about and communicates them to staff. Mr. Tassano said yes. He noted that he has talked with residents in that area Commissioner O'Connor inquired how delays are monitored at an intersection that is not signalized. Mr. Tassano replied that what he would do with a location like this where there is no existing use that generates trips is look for available gaps. He noted that it is a pretty straight - forward process where he sits at the intersection and judges as a driver how long it will take him to identify the vehicle that is downstream; then he has his five - second gap; he then judges on the other side what that five - second gap is, after which he tried to balance the number of gaps he has versus the number of vehicles he is going to have generated. Commissioner O'Connor inquired if the 30 trips or 70 trips coming into and going out of the projects only refer to peak hours and do not represent the total number of vehicles that go in and out that day: Mr. Tassano replied that was right. He explained that staff looks at traffic signals and traffic impacts during the worst time of the day, and the busiest time on West Las Positas Boulevard is during the PM peak hour, when there would be the fewest gaps to get onto that roadway. Commissioner O'Connor inquired if the 70 trips are just for one hour Mr. Tassano said yes. Commissioner Narum asked Mr. Tassano if he took the proposed childcare center into account when he looked at the traffic numbers for this project. Mr. Tassano said yes. He stated that the design capacity of West Las Positas Boulevard far exceeds the number of vehicles that are out there. He added that a lane on West Las Positas Boulevard is currently closed because of the sinking next to the creek, dropping the three lanes to two but still providing sufficient gaps. He continued that dropping it to a single lane would result in fewer gaps because everyone has to draw into a single lane and filter by the front. He indicated that West Las Positas Boulevard carries a lot of volume and that even with the additional traffic from the day PLANNING COMMISSION MINUTES, November 14, 2012 Page 25 of 31
