Project: Oakville to Oak Knoll, Group D

Description: The OVOK Project is comprised of four restoration groups (A-D) encompassing 23 sites. Groups A, B and C have been completed. These grant funds will support implementation of Phase 1 of the final group, Group D- sites 10, 9, 7, 4, and 3. Funding for this Project will be used to restore and enhance long-term river and floodplain function, improve the quality and resilience of aquatic and terrestrial riparian habitat, reduce property damage and sediment delivery associated with ongoing bank erosion processes, and achieve streambed sediment goals outlined in the Total Maximum Daily Load for the Napa River.

Reference Number: 3600BQ2096000

Implemented By: County of Napa

Objective: • Increase the quality and availability of off-channel habitat to improve rearing conditions for juvenile salmonids by creating 5 acres of new floodplain features and 1.2 acres of riparian freshwater wetlands. Anticipated outcome: enhanced geomorphic channel forms and processes that support a more diverse and complex instream condition. • Reduce excess sedimentation by applying biotechnical stabilization methods to 900 linear feet of streambanks in areas with active streambank erosion. Anticipated outcome: stable streambanks and a reduction in the amount of chronic and severe erosion within the project area. • Manage invasive non-native vegetation and plant native vegetation within 12.5 acres. Anticipated outcome: complex, resilient, native dominated riparian plant communities.
