If Stoneridge Drive is extended to the east and Jack London Boulevard is extended by Livermore, Vineyard A venue would be one of three parallel eastlwest surface streets.

As traffic congestion increases along I-580, regional cut-through traffic diverts to these parallel surface streets. Modifmg roadway and intersection capacity to meet this changing traffic demand is required to maintain LOS D or better conditions. Increasing capacity along Vineyard Avenue could help to reduce congestion along First Street, Stanley Boulevard and Bernal A venue by reducing delays along Vineyard Avenue and attracting more traffic to this corridor. However, the increasing traffic volumes along Vineyard Avenue have significantly reduced the number of gaps in traffic necessary to allow pedestrians to cross the roadway and motorists to access Vineyard Avenue from several existing side streets and driveways. The new realignment of Vineyard Avenue and the Specific Plan for the corridor will add even more public and private access points to new developent with similar problems relating to access, egress, pedestrian, school area, speed, and other safety issues. With the realignment of Vineyard A venue, staff has attempted to solve potential traffic problems by designing traffic calming roundabouts adjacent to Neal School and a traffic signal at the multi-use trail crossing X:\ADMIN\PGGS\Council2005\MEETINGlO0405\SR 05276 AttachmentI.doc Page 7
