The Project is located on Danville Boulevard between Jackson Way and Stone Valley Road in downtown Alamo, Southern Contra Costa County.  
  
The purpose of this Project is to improve traffic, bicycle, and pedestrian safety on Danville Boulevard between Jackson Way and Stone Valley Road by installing complete street improvements.

  
The Project includes constructing a roundabout and sidewalk improvements that include curb extensions, curb ramps, and entry medians at the Danville Boulevard/Orchard Court intersection. New curb extensions and curb ramps will be installed to meet Americans with Disabilities Act (ADA) requirements. Danville Boulevard currently has an existing five-lane configuration south of Orchard Court and four lanes north of the intersection. A newly constructed roundabout at the Danville Boulevard/Orchard Court intersection will reduce the lanes down to one lane at the approach to the roundabout, thus reducing traffic speeds entering the heavily used intersection. This will enhance bicycle and pedestrian mobility and safety. The project will maintain existing street drainage. Storm drain inlets will need to be relocated or adjusted to accommodate new curb and gutter locations associated with the new roundabout. Other Project features include road treatment slurry seal, signage modification, relocation of existing street lights and possibility of new street lights on Danville Boulevard to accommodate the new sidewalk location, and other roadside features. Utilities may need to be relocated or adjusted in order to ensure new sidewalk construction meets ADA clearance requirements. Mature oak trees within the existing sidewalk will be protected during reconstruction to the extent possible. However, it is anticipated that one oak tree will be removed and additional landscape trees may need to be removed to accommodate proposed improvements. The maximum depth of excavation is expected to be approximately four feet below the current grade. All roadway and sidewalk construction for this project will take place within existing roadway and urban areas.   
  
The Project will maintain the existing drainage pattern and will not create new impervious areas. Standard Best Management Practices (BMPs) will be implemented during construction. At least one lane will be open during construction activities. Emergency vehicles will have access at all times. Real Property transactions, including right-of-way acquisition may be necessary in support of this project.
