Document Description
The California Department of Transportation (Permittee) proposes in association with the Napa Valley Transportation Authority the construction of a tight diamond interchange with two multi-lane roundabouts on either side of SR-29. SR-29 will be rebuilt as an overcrossing north of the intersection with SR-221, providing separation between SR-29 and the SR-221 northbound ramp and the adjacent roundabout entry. SR-29 will continue to operate with two lanes in each direction. SR-221 will include two roundabouts with two lanes southbound and connecting to eastbound SR-29 and one lane northbound traveling from Soscol Ferry Road transitioning to SR-221 and single-lane ramp connectors from southbound SR-221 to westbound SR-29, and eastbound SR-29 to southbound on Soscol Ferry Road. The existing ramp connector from westbound SR-29 to northbound SR-221 will remain in place. The Project will include standard shoulders, curbs, gutters, and existing signage would remain in place. New signage will also be located within the Caltrans Right of Way (ROW). The Project will also include pedestrian and bicycle circulation, drainage work, landscaping, utilities, ground disturbance, earthwork and restoration. The Project will occur in six stages over the course of three construction seasons from 2022 to 2024.
The Project has an 87.87-acre Biological Study Area (BSA) that encompasses the Soscol Junction Interchange and all of the Caltrans Right-of-Way (ROW), collectively, the Project Area. The Project is expected to cause the permanent loss of 7.25 acres, the temporary loss of 10.09 of foraging habitat for the Covered Species, for a total of 17.34 acres of impact. This Project is also expected to cause the potential loss of one (1) known nesting occurrence within the Project Area. Project activities and their resulting impacts are expected to result in the incidental take of individuals of the Covered Species. The activities that are expected to result in incidental take of individuals of the Covered Species include initial site setup, equipment and material delivery, clearing and grubbing, site preparation, exclusionary fencing installations, environmentally sensitive area fencing installations, pavement and concrete removal, concrete pump truck activities, soil excavation, soil compaction, grading work, pavement installation, heavy equipment operation, trenching, construction vehicle traffic, general vehicle traffic and personnel on foot. The project is expected to result in incidental take of Swainson’s hawk take as defined by Fish and Game Code in the form of adverse impacts from excessive artificial light pollution, noise from the operation of heavy equipment and encroachment from individuals on foot that may result in nest abandonment and the loss of Covered Species eggs or juveniles, or in the form of capture to recover and transport injured Covered Species to care facilities of Swainson’s hawk, designated as a threatened species under CESA. The ITP referenced above as issued by CDFW authorizes incidental take of species listed under CESA that may occur as a result of Project implementation.
