Commissioner O’Connor said he was trying to understand cut-through traffic and where it is going and when. If we were to put in Stoneridge Drive today, he questioned where the 50% cut- through traffic would go within the city. Mr. Tassano said some of it is based on how much congestion the city creates in the Hacienda Business Park and how our levels of service decrease in the Hacienda Business Park. He said essentially, you have a straight west to east in the AM where people get off on El Charro instead of Santa Rita and Hacienda and continue along Stoneridge or West Las Positas depending on the congestion levels, and continue onto Foothill and up to I-580 or south to I-680 at Sunol. So there is a feathering across in the morning from west to east, with impacts to West Las Positas and Foothill. He said this is if it is not at build-out. There is some dependency on the level of congestion they currently have when they construct that roadway. In the PM, the majority of the traffic would be coming off of Foothill, Hopyard or Stoneridge Drive before they become so impacted that vehicles cannot get off, then going through the Hacienda business park depending on what the congestion levels are to get back to Stoneridge. Once they hit Stoneridge, they continue onto the east and out, either back through Jack London, onto the freeway, or up to the north onto Dublin and continuing the journey through their cut-through pass or back to the freeway. Commissioner O’Connor said it seems like most of the discussion surrounding the Stoneridge extension is that we get relief from Valley and he did not understand why without Stoneridge in place, we are talking about the Santa Rita, Valley and Stanley loop and why the loop would get so bad without Stoneridge. Mr. Tassano said in the AM when congestion increases on I-580 westbound, a large number of vehicles get off on El Charro. They drive down El Charro, continue onto either Busch Road or Stanley Boulevard and that is where those increases are seen. Commissioner O’Connor said he was actually talking about today. Mr. Tassano said the traffic is seen at that loop because the City is experiencing level of service D’s and E’s and F. In the AM, they have a large volume of traffic that gets off to the east of Pleasanton either going through Livermore or generating from Livermore. We only have the freeway and Stanley Boulevard essentially as they go west from the east. If they are generated in Livermore, the two choices are either the freeway or Stanley Boulevard. Using Stanley Boulevard, once you hit it at Pleasanton, you either have the choice of going south on I-680 by cutting through Sunol. If you want to go anywhere north and try to avoid the congestion at the I-580/I-680 interchange or the back-up at Hacienda, you go up Valley to Santa Rita and then over and across through Stoneridge. City Manager Fialho said people are either heading to work in Silicon Valley all the way out to I- 680 or others are heading to the business park and beyond. In the PM, the reverse is happening; they are coming out of the Stoneridge Drive road section, turning right on Santa Rita and left on Valley to get home, or they are coming from the South Bay and getting off on Sunol, cutting through First Street to get beyond Pleasanton into Livermore because I-580 is congested. Commissioner O’Connor referred to cut-through traffic percentages on the chart, with and without the Stoneridge extension, and confirmed with Mr. Tassano that the percentage of cut- through traffic remained the same on Valley and Stanley, but the volumes are very different. Mr. Tassano said the volumes are decreased and the percentages remain the same, so the cut- through volume will be decreased, as well. Mr. Tassano said on Valley in the AM without Stoneridge there is 3,000; with Stoneridge 2,500. In the PM, there are 3,890 without Stoneridge, and 3,300 with Stoneridge, or a 500 vehicle decrease. On Stanley Boulevard, there is 5,200 without and 4,900 with Stoneridge. He said if you were to total all columns there is Workshop Minutes 6 April 24, 2007
