Mr. Brozosky pointed out that Council had a two dimensional view of this area when it completed the Specific Plan and Council did not realize there was a slope. Mr. Knowles pointed out the difficulty of traffic at Petronave Lane and if a traffic signal had not been intended, staff would have had to take a second look at the site distance. Once it had been decided in the general scheme of designing the roadway there would be a signalized crossing, staff did not take other measures to assist vehicles to that location. Mr. Wilson pointed out that instead of making a left turn, a vehicle would only be able to make a right turn exiting Petronave Lane. Mr. Brozosky mentioned that Council had adopted a draft Traffic Circulation Element for the new General Plan. Although he voted against it, one of the items included in the Traffic Circulation Element was the widening of Vineyard Avenue to four-lanes. He asked staff if the draft Traffic Circulation Element and the traffic model needed to be modified to design Vineyard Avenue between Montevino Drive and Bernal Avenue as a two-lane street with medians? Mr. Knowles said staff did not use discretion in designing Alternative B. Staff took every roadway widening that was included in the 1996 General Plan and included it into the draft Traffic Circulation Element because it was aware that it would be a working draft. Staff was also aware that these later discussions would occur after the final land use. From the General Plan build out model runs from a year prior and in testing the sensitivity of each of these widenings, staff has an idea of the benefits and the impacts, and other than being able to pass a slower vehicle thus reducing delay slightly on this roadway, the striping test conducted has shown and demonstrated, based on staff's traffic simulations, that no large traffic backups are occurring. The main point of the temporary striping has borne out of the fact that everyone has been able to test drive it and decide if there are any fatal flaws and from a traffic engineering standpoint and in working with the neighbors to minimize noise and calm the neighborhoods, it has been a successful test. Mr. Brozosky agreed the striping has been successful; however, he wanted to point out one of the items included in the Traffic Circulation Element was the widening of Vineyard Avenue to four-lanes. He asked staff if the draft Traffic Circulation Element and the traffic model needed to be modified to design Vineyard Avenue between Montevino Drive and Bernal Avenue as a two-lane street with medians? Mr. Wilson said staff is recommending Council to authorize staff to proceed with the design of Vineyard Avenue between Montevino Drive and Bernal Avenue as a two-lane street with medians as there is sufficient time involved in preparing the design, and staff will also have the opportunity to address the draft Traffic Circulation Element. Ms. McGovern was not confident with any of the various options that staff had proposed for the roundabouts. She had a vision, which included the roundabouts, the opening of Neal School and traffic going between Livermore and Pleasanton and residents on Theissen Drive dropping their children off and going to work. She did not believe the roundabouts would be an adequate means for safe traffic control. Mr. Knowles said the roundabouts were designed in accordance with federal design guidelines and there is language within the guidelines that state the busier the side street is the better the roundabouts operate. The difficulty currently is that traffic on Vineyard Avenue is not used to traffic coming from the side streets and the closer traffic gets to a balanced flow, the Pleasanton City Council 18 1 0/04/05 Minutes
