Evening Peak Hour Congestion Levels At the 135 study intersections, traffic volumes collectively decrease by about 1,560 vehicles per hour (VPH) during the evening peak hour when the Foothill Road widening is removed from the 1996 General Plan Roadway Network. Traffic collectively decreases by about 545 VPH at the 37 intersections in the City with 35 seconds or more of average delay, and decreases by about 1,015 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. Afternoon School Traffic Significant congestion occurs along Foothill Road approaching and adjacent to Foothill High School in the afternoon as school lets out (prior to the P.M. peak hour). Traffic backups to West Las Positas Boulevard and to the south for several blocks are not uncommon. This impacts High School traffic, motorists trying to get to Lydiksen Elementary and all other motorists in the area. Widening Foothill road to four lanes from West Las Positas Boulevard to South Muirwood Drive would allow local drivers to pass the stopped northbound and southbound queues near the High School. This would significantly reduce travel time along Foothill Road without requiring significant widening north of West Las Positas Boulevard. Traffic Safety Widening sections of Foothill Road between South Muirwood Drive and Castlewood Drive to provide a 2-way left turn lane and bike lanes / paved shoulders, is not recognized by the traffic model as capacity enhancing. With or without these features, the roadway is modeled based on the two through lanes. However, this widening would significantly improve motor-vehicle, pedestrian and bicycle safety along Foothill Road in areas that currently have no shoulders, limited sight distance, and no left turn storage. 3. Hopyard Road Widening - Valley Avenue to Del Valle Parkway Proposed Widening/History The 1996 General Plan Roadway Network assumed that between the years 2000 and 2005, Hopyard Road would be widened to be a 4-lane divided roadway between Valley Avenue and Division Street. The General Plan also shows the intersection of Hopyard Road at Del Valle Parkway having a future traffic signal. The 1996 General Plan Roadway Network traffic model included these roadway features and the intersection lane geometry shown in Figure III-7. SR 05:027 Page 42
