shown to have ripple effects on routes throughout the City due to the limited total eastbound capacity and the high demand, both local and regionally, for these routes. West Las Positas Widening Both Alternatives A and B include widening to four lanes from Foothill Road to Payne Road, generally at the 1-680 overpass. Alternative A does not include an interchange. Not widening this segment shifts traffic onto Hopyard - Stoneridge and, potentially, onto local collectors due to the congestion on those streets. This widening would like reduce total miles traveled and hours spent driving on City streets. Regional cut-through is not expected to be affected. Also included in the model is a four lane, divided West Las Positas from Fairlands easterly to Park Place. This formerly four lane segment has been restriped to form a two lane street. This street functions as a neighborhood collector, and its widening has no effect on traffic shifts. Nevada Street Extension The 1996 General Plan roadway network assumed that between the years 2000 and 2005, Del Valle Parkway, now Nevada Street, would be extended as a 2-lane road with a two- way left turn lane from Bernal Avenue to Stanley Boulevard. The new street would connect to Stanley Boulevard to form the east leg of the First / Stanley intersection. The 1996 General Plan also shows the intersection of Bernal Avenue at Nevada Street as a future traffic signal-controlled intersection. The Alternatives B and C model runs include this extension. This extension would act as a link north of Arroyo Del Valle between residents on the east side of Pleasanton and schools and businesses in the center of town. In mornings this street attracts trips otherwise found on Bernal, Stanley and Vineyard (First to Bernal segment). It would reduce traffic volumes adjacent to the Vineyard Avenue park, senior housing, apartments, and single-family homes. No regional cut- through traffic uses this route directly; however, freed-up Stanley capacity may attract additional regional cut-through traffic. In afternoons, the street would again be primarily used by local trips from the City center to the southeastern residential areas. Little regional cut-through traffic is projected. The expected reduction in traffic on Vineyard between First and Bernal may allow traffic- calming measures to be applied to this street which is more residential collector than arterial in its design. Total vehicle-miles-traveled and travel times would be expected to be reduced with this extension. This extension reduces some of the traffic at Stanley-Bernal-Valley, a heavily congested intersection in all model runs.
