E1 Charro Road Extension The 1996 General Plan roadway network assumed that between the years 2005 and 2010 E1 Charro Road would be widened and extended to six lanes between 1-580 and Stoneridge Drive and four lanes from Stoneridge Drive to Stanley Boulevard. Dublin is currently in the process of widening the 1-580 interchange at E1 Charro / Fallon Road to provide a 4-lane overpass, 3-lane wide oft-ramps, loop on-ramps, and two traffic signal- controlled intersections. The segment between 1-580 and Jack London is assumed in all alternatives. In Alternative A it connects as a public street only to Jack London. In Alternatives A, B, and C it is extended from Jack London to Stanley. The El Charro Road extension would be primarily used by new traffic emanating from its adjoining new land uses (Staples Ranch, Hanson, Kie-Wit). It also forms a new north- south connector which provides access to Jack London (and Stoneridge if extended) and Stanley east-west routes and, thus, would attract regional cut-through traffic. Users of this extension are heavily influenced by potential connections to Stoneridge Drive and Busch Road (the latter is assumed in both the Alternative B and C model runs). The various model runs to date show widespread traffic effects throughout the City due to the E1 Charro extension and how it may or may not be connected to local streets. There have been a number of suggestions for how E1 Charro might be connected, or not, to other streets. These include: · No direct connection to Stoneridge Drive · Deleting the segment lying between Lakes H and I · No connection to Busch Road · Various combinations of the deleted segments listed above. These alternatives could be analyzed for their individual impacts. However, staff notes that the East Side area will have significant land use alternatives studied as well, and staff believes it is more fruitful to review the E1 Charro extension issues and additional street modifications in conjunction with various land use alternatives in the East Side area. West Las Positas Interchange The 1996 General Plan roadway network assumed the construction of a new interchange along 1-680 at West Las Positas Boulevard between the years 2005 and 2010. The new interchange included the widening of the overpass to 4-lanes and the construction of two traffic signal-controlled "T" intersections where the freeway on - and off-ramps intersected West Las Positas Boulevard. This interchange is included in Alternative C, but with ramp-metering. No 1-680 auxiliary lanes were assumed in Alternative C. Traffic using a West Las Positas interchange would have local trip ends from all over the City, but most trips are concentrated in the residential neighborhoods immediately to the west; in the Val Vista, Del Prado, and Pleasanton Valley neighborhoods; and the Hacienda business park. Regional cut-through traffic would also find this an option for east-west routes.
