About this file
This is an Engineer's Estimate document for the Napa Valley Vine Trail - Vista Carneros Segment, prepared by Napa County Department of Public Works. The estimate represents a 35% engineering design phase for a four-mile multiuse path project intended to close a gap in the 47-mile Napa Valley Vine Trail between John F. Kennedy Park and the intersection of Devlin Road at Airport Boulevard. The project encompasses demolition, grading, paving, utility work, drainage improvements, retaining walls, signage, and environmental permitting across both City of Napa and unincorporated County areas. Construction is anticipated to begin in Spring 2029, with the selected consultant providing preliminary engineering, environmental assessment, right-of-way services, plans, specifications, estimates, and construction support services through project completion in a turnkey delivery model.
The total project base bid estimate is $6,432,573, with a 15% contingency of $806,422.50, bringing the overall project total to $6,182,572.50. The estimate is segmented into three cost scenarios: Option A (Cost within City of Napa Limits) at $526,925, Option B (Cost within City of Napa Limits) at $449,071, and Cost within County Limits at $5,905,648. Major cost components include earthwork ($300,000), asphalt concrete ($540,000), class 2 aggregate base ($600,000), retaining walls ($312,000), and storm drain/drainage systems ($250,000). The project requires compliance with Caltrans Local Assistance Procedures, and funding sources are not specified in this engineering estimate document.
