Minutes Planning Commissior, January 22, 1986 than the figures currently used. Mr. Swift stated that these numbers are based on actual trips. Commissioner Innes did not support changing the methodology when empirical data will be available this Fall. Mr. Swift felt that the proposed assumptions are more defensible than the ones currently used. Commissioner Innes felt that as it relates to 20% increase in capacity at peak hours, there is a lot of change for a little bit of data. Mr. Swift acknowledged that this is correct. Ben Tarver, 1144 Arak Court, had the same problem as the environmental monitoring committee. He felt the material is difficult to understand and thanked Mr. Swift for explaining it to him. A lot of improvements planned will alleviate a lot of the problems. In the short term development will either have to be stopped or assumptions changed to allow development. He stated from a resident's point of view that it is better to stay on the conservative side. Brian Benda, 4820 Smith Gate Court, suggested changes be based on real North Pleasanton traffic data. If not available, standards should be applied in consistent fashion. It is difficult to argue with the changes proposed when they are based on actual data in North Pleasanton. Regarding trip generation - changes recommended are in excess of 20%. This is not from Pleasanton data. If you take No. Pleasanton data (the Hacienda Business Park buildings in the Caltrans studies) and reduce it by 25%, you still come up with numbers greater than the proposed trip generation rate. He recommended the trip generation rate not be changed until the Fall when data from North Pleasanton would dictate trip generation rates. Commissioner Innes asked Mr. Benda if he had reviewed the Oak Creek Study and what comments he has relative to the study after reviewing it. Mr. Benda indicated that a study based on a single business park may not be relative to the CIty of Pleasanton and is perhaps arbitrary. Chris Kinzel, TJKM., indicated that they were going to do studies of the Bay Area and determined that Caltrans was in the process of doing a Bay Area wide study of business parks to find out what trip rates would apply. They analyzed the Caltrans data and determined it is on the conservative side because their peak hour calculations cover a period of noon til midnight. He reviewed the definition of peak hours. He stated their studies have been changed to reflect the change in uses at such complexes as the Chabot Center where there are uses more intensive such as a bank located in it. Commissioner Michelotti discussed lane capacity comparing 1984/85 studies and asked what would change them. Mr. Kinzel indicated that the volume moving through the intersections and that after traffic levels change the volume to capacity would change. Commissioner Innes asked Mr. Kinzel about the Oak Creek study used. He felt the study was made prior to one of the larger users moving into the area. He didn't feel it would necessarily - 9 - _ _ _ _ _ T. __ __...,. _ _ _.
