Dowling Associates, Inc. ~, ~ ;, Transportation Engineering • Planning• Research • Education Traffic Analysis RUBY HILL CONVERSION PLEASANTON, CALIFORNIA Introduction and Summary Dowling Associates, Inc. was retained by the City of Pleasanton to conduct a traffic assessment for the proposed conversion of the existing Ruby Hill sales office to a 5,000 square foot quality restaurant. Access to the project site is to be provided on Vineyard Avenue 800 feet westerly of Ruby Hill Boulevard. The study area is presented in Figure 1. The proposed project does not degrade the levels of service (LOS) from acceptable to unacceptable levels at any of the study intersections. The project would, however, add trips to the intersection of Stanley Boulevard & Valley Avenue, which already operates at an unacceptable level of service under Existing+Approved and the Cumulative base conditions. The purpose of this study is to determine the potential traffic impacts of the proposed Ruby Hill project located near the intersection of Vineyard Avenue & Ruby Hill Boulevard. Methodology The methodology used in this analysis is outlined below. 1. The Existing+Approved AM and PM peak hour traffic conditions were determined at the study intersections. The Existing+Approved traffic volumes consist of the 2003 background data volumes from the Synchro traffic analysis software files provided by the City of Pleasanton and the traffic generated by the approved Bernal Property Phase II development. The peak hour levels of service were calculated for the study intersections. 2. The Existing+Approved+project traffic conditions were estimated for the proposed Ruby Hill 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 resultant peak hour levels of service for the study intersections.
