City of Pleasanton, CA - City Council Page 3 of 12 Ms. Roberts thought the 2003 model had taken out West Las Positas. Mr. Knowles referred to page 64 of the 2003 baseline report, Table 18, which describes everything omitted in the model from the General Plan. As staff works through the General Plan and prepares environmental documents, it must know what would have happened if the General Plan were built out unchanged. From this point, decisions can be made on what to add or take out. Mr. Arkin felt it would be beneficial to have the political discussion on whether to delete West Las Positas and Stoneridge and then for the next five meetings that confusion would be removed. These issues have been discussed for years. Mr. Swift said when discussion reaches the combined alternatives; there will be models without those streets. There will be many alternatives. However, before you get to that point and before the General Plan is changed, there must be analysis of what happens if the General Plan is built as is. There will be models with everything included and there will be models with many things changed. Staff believed it would be easier to consider each point individually before getting to those issues of concern, such as West Las Positas, Rose Avenue, Stoneridge Drive, Foothill Road, etc. Ms. McGovern asked for an explanation of Level of Service. Mr. Swift indicated it is in the Baseline Report and reviewed the average delay per signal light phase for each Level of Service. Mr. Knowles added his remarks to clarifY levels of service. Ms. McGovern hoped the goal was that a person did not have to wait at a signal longer than 55 seconds. Ms. Fox inquired about Table I on page 7 and referred to the problems at Santa Rita and 1- 580 eastbound on-ramp. She felt it should be LOS F rather than LOS C. Mr. Swift said on-ramp metering is included at this intersection. When the intersection gets full, vehicles go to other intersections in the area to get onto the freeway. The traffic model assumes the ramp meter rate until the year 2025. Ms. Fox did not think the LOS C accurately reflected the actual wait to get onto the freeway and should be changed. Mr. Blank felt if the model is artificially limited, he did not think it was providing an accurate view of the intersection. Mr. Swift said there could be a demand based model output, which shows vehicles going wherever the drivers want regardless of lanes on the road, or if the freeway is full. It just shows where the cars go. The current model is a constrained model, which is based on shortest time and indicates when a particular road is full; cars will go another route. Mr. Blank stated that conceivably the user experience could be considerably different than what is shown on the model, because the model is constrained. http://www.ci.pleasanton.ca.us/archive/ccwsminutes050111.htmI 8/22/2006
