The project will also complete the landscaping of Amador Valley Blvd. from Amador Plaza Road to Village Parkway and will complete the signal interconnect link from Dublin Boulevard north on Village Parkway and the west on Amador Valley Blvd. to San Ramon Road. In addition, the second left turn lane from eastbound Dublin Boulevard to northbound Village Parkway has been added to this project in order to obtain the best possible construction cost. This modification was requested by the City Council and will significantly improve the level of service at the Dublin Blvd./Village Parkway intersection. This project is included in the 1987-88 and 1988-89 Fiscal Years' Capital Improvement Program budgets. Both intersections receiving new signals have met the warrants for the installation of traffic signals. Because of the new signal at Amador Valley Blvd. and Amador Plaza Road, the left turn storage bay from westbound to southbound must be extended. This will affect the church driveway on the north side of the street by moving the opening to the east, making a "U" turn necessary rather than a direct turn-in.
