The Home Depot volumes that use Bernal Avenue will require longer green times than are currently programmed at the intersection. The retiming of this inter- section improves the LOS to "D". The traffic study also identifies that the Bernal Avenue/Valley Avenue and the Sunol Boule- vard/I-680 Northbound Ramps will operate at LOS "E" with/without the project. The following table describes the traffic that the Home Depot project will add to these intersections and the added delay: Table 4: Home Depot's Impacts to the BernaWalley and the Sunol/I-680 NB Intersections __ - Added ~ Added AM de- ~ Added r Added PM De- AM Trips lay (seconds) PM Trips lay (seconds) - ___ __ -- Bernal Avenue a~ Valley Avenue 8 0.

Staff has received questions regarding the Stanley Boulevard @ Valley Avenue/ Bernal Avenue intersection. For the existing plus approved scenario, "Table 3 -Intersection Levels Of Service" shows the Stanley Boulevard/Valley Avenue/Bernal Avenue intersection without the project op- erating at Levels-of-Service (LOS) "F" (106.8 seconds delay) and "B" (68.6 seconds delay) for the a.m./p.m. peak hours. With the project, the level of service remains the same, but the delay times increase to 111.2 seconds delay in the a.m. peak hour and 74.5 seconds delay in the p.n. peak hour.
