• Project trip generation for the proposed project was developed based on trip generation rates contained in the Institute of Transportation Engineers (ITE) publication Trip Generation, 9th Edition. This is a standard reference used by jurisdictions throughout the country and is based on actual trip generation studies at numerous locations in areas of various populations. The convenience market is expected to generate approximately 165 additional trips in the a.m. peak hours and approximately 129 additional trips in the p.m. peak hours, based on the AM trip generation rate of 67.03 trips per 1,000 square feet of building space and the PM trip generation rate of 52.41 trips per 1,000 square feet. The ITE handbook indicates that approximately 50% of the trips to a convenience market are pass-by trips, i.e., trips associated with motorists who are already on the road and making a stop on their way to another destination. Taking pass-by trips into account, the project would generate 83 net new trips in the a.m. peak hours and 65 net new trips in the p.m. peak hours. This is not a significant increase in the peak hours. In addition the carwash would not be expected to generate a substantial number of independent vehicle trips because trips to the carwash would typically occur in conjunction with trips to the gas pumps and/or convenience market. The City's 2005-2025 General Plan Circulation Element includes existing and peak-hour traffic volumes on major roadways, and peak-hour volumes expected to occur at buildout of the General Plan. Table 5 below shows the existing and anticipated a.m. and p.m. peak-hour traffic volumes on Santa Rita Road and W. Las Positas Boulevard: Table 5: Existing and Buildout Traffic at Peak Hours Existing A.M. Buildout Existing P.M.

The Pleasanton General Plan requires site-specific traffic studies for all major developments which have the potential to exceed Level of Service (LOS) D at major intersections and requires developers to implement the mitigation measures identified in these studies in order to maintain LOS D or better. Exceptions are made for the Downtown and Gateway Intersections' where the LOS D or better standard may be exceeded. The General Plan indicates the existing LOS during the p.m. peak-hour at W. Las Positas Boulevard and Santa Rita Road is LOS C. At General Plan buildout, the LOS at the intersection would be LOS D. As the proposed project would generate a small amount of Per the General Plan, consideration may be given to traffic improvements at Gateway Intersections when it is determined that such improvements are necessary and are consistent with maintaining visual character, landscaping, and pedestrian amenities.
