Dowling Associates, Inc. 1 Transportation Engineering • Planning • Research • Education ~ ' Transit service is provided along Stanley Boulevard by Wheels Route 10, which serves Dublin, Pleasanton and Livermore. Weekday peak hour headways along this route are 15 minutes, while weekday off-peak and weekend headways are 20-40 minutes. Wheels is a service of the Livermore Amador Valley Transit Authority (LAVTA). The purpose of this analysis is to determine the potential traffic impacts of the proposed Home Depot Shopping Center project to be located near the intersection of Bernal Avenue & Stanley Boulevard. Methodology The methodology used in this analysis is outlined below. The Existing+Approved AM and PM peak hour traffic conditions were determined at the 44 existing study intersections. The existing+approved traffic volumes were provided by the City of Pleasanton in the associated Synchro traffic analysis software files. The peak hour Levels of Service (LOS) were then calculated for the study intersections. The Existing+Approved+Project Without Loop Road traffic conditions were then estimated for the Home Depot Shopping Center project. This involved estimating the project's trip generation and trip distribution; adding the project's peak hour trips to the Existing+Approved peak hour volumes; and calculating the peak hour LOS for the study intersections. The Existing+Approved+Project With Loop Road traffic conditions were also estimated for the Home Depot Shopping Center project. This assumed the same project trip generation and trip distribution; however, it also included a perimeter loop road adjacent to the project site. The peak hour LOS was calculated for the study intersections. 4. The level of service results were then analyzed to determine if any mitigation measures would be needed to maintain an acceptable peak hour LOS at the study intersections for either of the Existing+Approved+Project analysis scenarios. The acceptable LOS is based on the City's standard, which is Level of Service D (some exemptions exist). Traffic operational analyses were used to determine the need for mitigation measures. Existing+Approved Traffic Volumes Traffic data was obtained from the City of Pleasanton for the study intersections (Figure 1) of: (1) Bernal & Case (Signalized) (2) Bernal & First/Sunol (Signalized) Traffic Analysis Page 3 Home Depot Shopping Center, Pleasanton
