Project Location:

Boronda Road between Dartmouth Way and Hemingway Drive.

Project Description:

On May 16, 2017, the City Council approved the roundabout concept along East Boronda Road at the following intersections: McKinnon Street, El Dorado Drive, Natividad Road, Independence Boulevard, and Hemingway Drive.  The roundabouts will be constructed in conjunction with the Boronda Road Congestion Relief Project (between Dartmouth Way and Independence Boulevard).

The project will widen East Boronda Road into a four-lane roadway with landscaped median, and bike lanes.  The existing bridge over Gabilan Creek (near Independence Boulevard) will also be widened to accommodate the four-lane roadway with bike lanes and sidewalks.  Construction of the roundabout at Hemingway Drive may be added to the scope of work to this project or may be built as a separate project by the developer within the Central Area of the Future Growth Area.

Project Update:

The Boronda Road Congestion Relief Project will occur in three phases. The first phase of the project would include widening of East Boronda Road from just east of Dartmouth Way to approximately 1,900 feet east of McKinnon Street for a total length of approximately 3,500 feet. It would also include a roundabout at the intersection of McKinnon Street and East Boronda Road. Existing agricultural and roadside drainage ditches situated along the north side of East Boronda Road would be relocated to the north to accommodate the roadway widening.

The second phase of the project would continue the widening of east Boronda Road from the Phase 1 limit to approximately 1,100 feet east of Natividad Road. It would also include roundabouts at the intersections of El Dorado Drive and Natividad Road.

The remainder of the improvements including the widening of the bridge crossing Gabilan Creek, and the construction of a roundabout at the intersection of Independence Boulevard and East Boronda Road would be constructed as the last phase of the project.

Construction of a roundabout at Hemingway Drive may be added to the scope of work to this project at any of its phases, or may be built as a separate project by the developer.   

The Project’s field surveys have been completed, and environmental work is currently underway. 

Phase 1 Project Update:

The final layout of the McKinnon Roundabout (Phase 1 Project) has been completed. With this completion, the development of the right-of-way plats/drawings and legal descriptions for the Phase 1 right-of-way acquisition is underway. The detailed design for Phase 1 is also underway, with completion scheduled for December 2020 and bidding and award of the construction contract following thereafter. Meeting this schedule is contingent upon:

The IS/MND for this project will be published and distributed in June 2020. The comment period will be for 30 days.

1.    Completion of the right-of-way acquisition for this Phase 1 segment. The right-of way acquisition will be one of the items to be discussed as part of the development agreement negotiations between the City and the West Area Specific Plan Developers/Owners.

2.    Issuance of a permit by the Army Corp of Engineers (ACOE) for a jurisdictional wetland within the McKinnon Roundabout boundaries. Owing to the recent Federal government shutdown, the backlog of ACOE’s workload will likely impact applications.

Concurrent to the McKinnon Roundabout design, the ultimate layout of the El Dorado, Natividad, and Independence Roundabouts is under design so they can also be included in the development agreement negotiations for the West Area and Central Area Specific Plans.
