For the major alternatives, the model runs show where users ora street link come from, the shifts of traffic from local streets to others to complete local trips, and total traffic changes in terms of miles driven/hours driven on local streets. No levels-of-service calculations were made at this time. The intent at this stage of the analysis was to see who street users are and where shifts in traffic were likely to occur. In general, it is safe to assume that congestion is likely to increase on routes where traffic is shifted, especially at major arterial intersections. (The shifts in traffic are difficult to reproduce at a legible scale for most alternatives; these will be clearly displayed at the meeting.) The alternatives/options which will be explored include the following: Planned street widenings: 1. Bemal Avenue Widening - four lanes from Foothill Road to 1-680; four lanes from First Street to Independence Drive; four lanes from Angela Street to Nevada Street. 2. Foothill Road Widening - four lanes from Stoneridge Drive to Muirwood Drive South; two lanes plus two-way left-mm lane Muirwood Drive South to Castlewood Drive. 3. Hopyard Road Widening- four lanes from Valley Avenue to Del Valle Parkway. 4. Dublin Canyon Road Widening - four lanes from Foothill Road to west City limit. 5. Vineyard Avenue Widening - four lanes from Bemal Avenue to 4,000 feet east of Bemal Avenue (approximately Clara Lane). 6. West Las Positas Boulevard Widening - four lanes from Santa Rita Road to Park Place; four lanes from Foothill Road to Payne Road. Planned street extensions: 7. Nevada Street Extension - Bernal Avenue to First Street/Stanley Boulevard. 8. Rose Avenue Extension - west end to Valley Avenue. 9. Stoneridge Drive Extension - east end to E1 Charro Road. 10. E1 Charro Road Extension - 1-580 to Stanley Boulevard. Planned freeway interchange: 11. West Las Positas Boulevard Interchange ~ 1-680. Each of the above will be deleted from the planned network, as described above, to model the changes. No new streets were suggested be added to the 1996 General Plan network; however, should such a new street be proposed, it, too, could be similarly modeled. The results of the model runs, together with a brief history of the street planning and financing considerations, follow. The planned street widenings comprise this Part I report; the street extension/interchange will be found in a subsequent Part II report. SR 05:027 Page 24
