pLEASANTON" JOINT WORKSHOP OF THE CITY COUNCIL AND PLANNING COMMISSION AGENDA REPORT April 24, 2007 Planning and Public Works TITLE: GENERAL PLAN WORKSHOP DISCUSSION ON THE RESULTS OF GENERAL PLAN TRAFFIC MODELING WITHOUT AND WITH THE STONERIDGE DRIVE EXTENSION SUMMARY This report describes the results of traffic modeling for the General Plan. Six scenarios were modeled: three land use options (the Preferred Land Use Plan, Dispersed Growth Plan, and Concentrated Residential/Transit Oriented Development (TOO) Mixed Use), and, for each of the land use scenarios, two circulation network options (the "Working Draft" circulation network without the Stoneridge Drive extension, and the "Working Draft" circulation network with the Stoneridge Drive extension). There are few significant differences in traffic volumes or intersection levels of service operation between the three different land use options. Each option creates its own minor shifts in traffic. However, no land use option results in a significant change in mitigation measures needed to maintain an acceptable level of service. Unlike the land use options, the construction of Stoneridge Drive results in a significant redistribution of traffic volumes. The re-distribution that is created by the Stoneridge Drive Extension provides relief on heavily traveled routes such as Hacienda Drive south of 1-580, Santa Rita Road south of 1-580 and Valley Avenue between Santa Rita Road and Busch Road. The Stoneridge Drive extension does not reduce the number of level of service E or F intersections city-wide, but does reduce the delay at most of the intersections which also reduces the level of mitigation necessary to maintain acceptable levels of service. RECOMMENDATION Receive information concerning the results of traffic modeling and hear public comment. Adjourn to the May 1, 2007 City Council meeting to take action on a preferred circulation network and land use plan to be used as the basis for completing the Draft General Plan and the Environmental Impact Report.
