from LOS B to LOS C in cumulative. Even the near term with the project without <br />cumulative, there is degradation from LOS B to LOS C there. He said if 890 trips are <br />added, he asked what traffic would be like at this level. <br />City Traffic Engineer Mike Tassano said 890 trips sounds like a lot and he would be <br />concerned with adding that in a peak hour; however, the way to look at it is that <br />10 percent occur in each peak, or 90 trips. The 90 trips are taken and distributed. Half <br />may go down First Street, the other half down Old Stanley, and some toward Livermore. <br />The direction of travel is broken down in the transportation study. <br />When distilling down the 90 trips that leave or come back in the p.m. peak hour, half of <br />them, or 45 vehicles, are now on First Street. This is a little less than one per minute. <br />With this development, instead of three cars at a traffic signal, there may be four or five <br />cars. <br />Mr. Tassano said added to this are the trips from the 345 units from residential <br />development occurring on the Auf der Maur property which is included in the <br />transportation study, and the question asked is what other traffic in Livermore and <br />Dublin contributes towards Pleasanton's LOS. They then conduct a cumulative analysis <br />and they look at how those new traffic volumes are written out and they get to the level <br />of service. <br />One of drawbacks in looking at LOS, if there is a heavily traveled corridor in one <br />direction he can add a lot more traffic to that because Pleasanton does not have a lot of <br />cross streets. When sitting on Neal Street and someone wants to cross First Street, that <br />traffic volume is light. So instead of having the car wait 30 seconds, they can delay the <br />lights another 30 seconds which allows many more cars through on the main street. <br />Commissioner Brown asked and confirmed with Mr. Tassano the 345 units would be <br />included and forecasted into the model. He referred to Row 11, page 108, and said <br />when looking at the p.m. peak, the delay today is 25 seconds and it will go to <br />48 seconds, and with this project it would go to 50 seconds per vehicle. The change will <br />be a lot from 25 seconds to 48 seconds, but not much from 48 to 50. Therefore, today <br />when compared to in the future, traffic on First Street will have much longer delays, and <br />Mr. Tassano agreed. <br />Chair Ritter referred to the three options which are: (1) the current proposal with <br />93 homes; (2) the Housing Element with more apartments; and (3) to leave as is <br />scenario with office and zoning. He confirmed with Mr. Tassano that the least amount of <br />traffic impact would be the 93 homes unless going to all warehouse. <br />Mr. Tassano said all analysis included having Nevada Street extended because this is a <br />much more equitable way to analyze this project. <br />Commissioner Nagler asked what the impact on traffic would be with the Nevada Street <br />extension. <br />PLANNING COMMISSION MINUTES, August 10, 2016 Page 6 of 33 <br />
