traffic will be delayed downstream at Sunol Boulevard and Sycamore Road and at Bemal Avenue. The 1996 General Plan shows this intersection as a future traffic signal location. It is recommended that a 3-way stop be initially installed to improve traffic safety and limit cut-through traffic at this intersection. It is also recommended that this intersection be included in the list of future traffic signals so that it can be included in developer traffic impact fee calculations for construction in the future if traffic delays begin to impact residents in southwest Pleasanton. Sunol Boulevard at Sycamore Road Gateway Traffic Metering - LOS Policy Exemption All Year 2025 traffic model forecasts assume full occupancy of the Applied Biosystems site. Under these conditions, traffic delays increase to LOS E and F conditions. The traffic model has been set to calculate LOS conditions assuming enough green time will be given to east/west traffic to clear local traffic in one green light, and whatever time is left over will be given to inbound traffic on Sunol Boulevard which contains 50% or more cut-through traffic at this intersection. This policy helps to minimize local resident delay, while also limiting cut-through traffic volumes. However, favoring the local residents on Sycamore Road will increase delay on Sunol Boulevard during the evening commute period, and the overall intersection LOS degrades to LOS E and F conditions. Allowing this gateway to be constrained requires a gateway LOS exemption of the citywide LOS D standard. Valley Avenue at Blackbird Drive / Northway Road (W) Mitigation - Construct new traffic signal In all Year 2025 scenarios, the flow of traffic along Valley Avenue exceeds the capacity of the stop sign controls at this intersection, resulting in LOS F conditions on Valley Avenue. Stop sign controls have far less capacity than traffic signal control. This was recently demonstrated at Vineyard Avenue at Montevino Drive where traffic backups were eliminated when the signal replaced the previous 4-way stop. Installing a traffic signal at this intersection would improve pedestrian safety, while reducing delay for Pleasanton residents, and would also help to reduce traffic diversion onto Black Avenue and Del Valle Parkway. Valley Avenue at Busch Road Mitigation - Construct second westbound right turn lane If Busch Road is extended to E1 Charro Road, and E1 Charro Road provides a connection to Stanley Boulevard, a second westbound right turn lane will need to be constructed for traffic turning from Busch Road to Valley Avenue. This mitigation is assumed in all scenarios that include the Busch Road and E1 Charro Road extensions. Valley Avenue at Crestline Road Mitigation - Construct new traffic signal In all Year 2025 scenarios, the flow of traffic along Valley Avenue exceeds the capacity of the stop sign controls at this intersection, resulting in LOS F conditions on Valley Avenue. Stop sign controls have far less capacity than traffic signal control. This was recently demonstrated at Vineyard Avenue at Montevino Drive where traffic backups were eliminated when the signal replaced the previous 4-way stop. Installing a traffic signal at this intersection would improve pedestrian safety, while reducing 14
