MINUTES PLANNING COMMISSION 7/11/84 Page 7 Chris Kinzel, TJKM, 4637 Chabot Drive, presented background concerning traffic studies that they have done for Sites 22, 31A and 37 recently. This report was the 12th in a series for the North Pleasanton Area. He presented slides entitled Steps in Typical Traffic Studies, Existing LOS in Pleasanton November 1984, Land Uses, Street Improvements in Place by 1986, TSM Assumptions, Distribution of Traffic, Results of 6/14/86 Study, Key Requirements in North Pleasanton, Conceptual Volume, Capacity Time, Proposed Monitoring Location. Mr. Kinzel reviewed each slide in detail. Vice Chairman Wilson asked Mr. Kinzel to expand on the slide concerning distribution of traffic from proposed develoFn;ents. Mr. Kinzel indicated that so far they have determined that the mitigation measures anticipated and planned for are going to be satisfied. The ultimate width of the streets are known based on previous studies. Commissioner Innes asked if what Mr. Kinzel was saying is that as far as can be determined additional mitigation measures are not necessary over those that will be planned to be in place by 1986. Mr. Kinzel inc'.icated that this is a correct assumption. There is perhaps one location where additional mitigation measures have been considered and he would be addressing this later in his presentation. Vice Chairman Wilson asked if one of the mitigation measures would be the enactment of a TSM Ordinance. Mr. Kinzel said that this is correct. Mr. Kinzel stated that there are two intersections which will be at LOS "F" ar.d they are both in Dublin, there will be four intersections with LOS "D" in Pleasnton. These opinions are based on the street patterns and situations which existed or were known to have existed in November 1983. In their 6/14/84 Study they considered developments which are not 100% occupied but built in the City. Black Angus, etc. are not included in the study as adding additional traffic since they are built ar.d occLFied and the traffic trips were actually counted. Mr. Kinzel reviewed the TSM assumptions used and felt that the goals are fairly easily achievable. Based on a preliminary study, it appears in some cases the 10% ride sharing and 25% flex time goals are being exceeded at the present time. In the building in which he works 8% of the people are carpooling and 33% are not driving during the peak hours. He stated that Karen Fraser-Middleton, the TSM Coordinator is present tonight to address this issue. He then presented his slide entitled "Distribution of Traffic" and explained that they have changed their method on distribution from the previous studies. He reviewed the previous figures and assumptions. They felt that these figures were valid. Therefore, it is important to continually monitor traffic and make adjustments in projections. Fortunately for Pleasnton, traffic will be continually monitored, therefore, unlike any other area in California, Pleasanton can have control over the situation. He indicated that Albert J. Gallardo formerly of the FHWA is also present to address major interchanges in North Pleasanton. Caltrans plans to widen 680 to six lanes and 580 to four lanes. Commissioner Wilson inquired about the LOS shown on Mr. Kinzel's Table 1 regarding trip generation and asked if these have taken into consideration the TSM and LOS update. -7- _r
