MINUTES PT ^NNING COMMT_~°ION 7/11/84 Page 8 Mr. Kinzel responded that they have made certain assumptions as to how much TSM would be occuring by the time the study is operative. Commissioner Innes and Mr. Kinzel discussed the technicalities of the TSM with Mr. Kinzel pointing out that all assumptions have been overstated. He indicated that traffic would go up 35-40% without improvements being put in but because of the TSM the numbers should go up 2-3 points. TSM is already being used by many people. Commissioner Innes then addressed peak hour traffic and the percentage of average daily trips. Mr. Kinzel explained the method which was used to ascertain the counts. Commissioner Innes had concerns with a difference in traffic projections between Caltrans and TJKM. Mr. Kinzel explained that in one building alone there was a 33% diversion in traffic. Caltrans does not take into consideration conditions which apply in Pleasanton for example TSM which could result in a 40% reduction in traffic. Commissioner Innes then posed a hypothetical question to Mr. Kinzel relating to LOS using assumptions of 100 cars going down Hopyard to Stoneridge Drive and then to Foothill Road and if 15% turned right, he asked if that would significantly impact the LOS. Mr. Kinzel said the answer is probably yes, but it would depend on the straight across movement and if it was a critical movement or not. That is one of the reasons why there are free right-turn lanes. Mr. Kinzel indicated that Owens and Chabot extensions have reduced LOS. Commissionerlnnes referred to slide number five and asked why the Stoneridge Extension across Santa Rita Road was used when the extension has not been approved yet. Mr. Kinzel explained that the subject intersection is not even close to critical. Improvement plans are in the works now and construction will begin 1985 with completion by 1986. Commissionerlnnes referred to the November 1983 traffic study done for Hacienda Business Park and north Pleasanton development and Table 3 of that report concerning the development of Ponderosa Homes, Barratt, Crocker Homes and other residential development in the Valley. Mr. Kinzel reported that the Planning Commission and City Council in approving the Hacienda PUD required that a traffic study be done for each development proposed at the time of design review submittal. They worked out a method acceptable to City staff and in the spirit of the approval to use the number of employees, buildings in Pleasanton, etc. This did not include any residential development. The assumptions do take into consideration traffic in central and south Pleasanton that would add to the traffic problems in the north part of town. There will be continuous monitoring of traffic throughout Pleasanton. Commissioner Innes asked if the LOS will be monitored by Multi-Sonics. Mr. Kinzel indicated that this is the case. Commissioner Innes commented that some intersections will not be hooked up to the monitoring system until 1986 and asked if this is still true. Mr. Kinzel explained that it is staff's intention to have all intersections on line. The critical intersections such as Hopyard/Stoneridge etc. will hopefully be operative in 1985/86. Commissioner Wellman thanked Mr. Kinzel for his informative presentation. Al Gallardo, Bissell and Karn, 3814 Moddison Avenue, Sacramento, CA 95819, indicated that the developers are keeping very close contact with Caltrans and have certain assurances from them on time frames for completion of certain improvements. Commissioner Innes asked about the timeframe for Hacienda interchange. Mr. Gallardo indicated that it would probably take place 1986-87. -8- _._ _ _~_
