number of cut-through vehicles in the City, but would not divert cut-through traffic onto neighborhood streets. Evening Peak Hour Congestion Levels At the 135 study intersections, traffic volumes collectively decrease by about 1,660 vehicles per hour (VPH) during the evening peak hour when the Bemal Avenue widening is removed from the 1996 General Plan Roadway Network. Traffic collectively decreases by about 265 VPH at the 37 intersections in the City with 35 seconds or more of average delay, and decreases by about 1,395 VPH at the 98 other study intersections when the road widening is removed from the network. Due to the number of possible roadway alternative combinations, the resulting LOS calculations will be performed based on future traffic model runs based on a more refined roadway network alternatives combination. The above traffic increases or decreases may occur on non-critical approaches to many intersections and have little impact on congestion at the intersections. Bernal Avenue - West of 1-680 This widening was reviewed at the same time as the other Bernal Avenue analysis described above. Not widening this section of road (I-680 to Foothill) would switch fewer than 100 vehicles in any peak hour to alternative routes (with the largest shift being A.M. traffic using 1-680 to West Las Positas as an alternative route to school). The shifts are minor in nature, and the satisfactory LOS at the Foothill-Bernal intersection would not change. The full numerical analysis can be made available should the Commission/Council wish. 2. Foothill Road Widening Proposed Widening/History The 1996 General Plan Roadway Network assumed that several sections of Bemal Avenue were to be widened or re-striped to provide additional travel lanes. 1995 to 2000: 2000 to 2005: Re-stripe to create a six--lane divided road from 1-580 to Stoneridge Drive. Widen to create a four-lane divided road from Stoneridge Drive to Muirwood Drive South. Widen to create a three-lane with two-way left-turn lane from Muirwood Drive South to Castlewood Drive. The 1996 General Plan Roadway Network traffic model included these roadway features and the intersection lane geometries shown in General Plan Figure 1II-7. Keeping Foothill Road "rural" in character has been a long-standing City goal. However, it has also been a goal to satisfactorily and safely accommodate local traffic using the street.
