About this file

This is a project schedule document for the Napa Valley Vine Trail - Vista Carneros Gap Closure Project, a multiuse path initiative involving Napa County Department of Public Works. The project aims to complete a four-mile gap in the 47-mile Napa Valley Vine Trail between John F. Kennedy Park and the intersection of Devlin Road at Airport Boulevard. Napa County is procuring a single prime consultant through an RFP to provide comprehensive services including preliminary engineering, environmental assessment, right-of-way work, plans, specifications, estimate preparation, and construction support services. The consultant selection and negotiation process is scheduled to occur between September 23 and October 13, 2026, with board approval of the consultant agreement anticipated on November 3, 2026. The project timeline indicates construction is targeted to commence in spring 2029, with the notice to proceed scheduled for September 3, 2029, and construction duration estimated at 180 days through mid-July 2030.

The schedule reflects a comprehensive design and permitting phase spanning from late 2026 through early 2029, encompassing multiple technical and administrative milestones. Key permitting activities include CDFW Streambed Alteration Agreement, Regional Water Quality Control Board 401 certification, and U.S. Army Corps of Engineers 404 permit reviews, all scheduled between April and December 2028. The project incorporates environmental studies and NEPA documentation review extending from March 2027 through May 2028. Right-of-way certification is scheduled for completion by April 2029, with bid advertisement planned for June 2029 and board award on August 7, 2029. The consultant is required to manage all turnkey services in accordance with Caltrans Local Assistance Procedures, including administrative documentation, responses to Caltrans requirements, and ongoing design support throughout construction.
