Document Description
The California Department of Fish and Wildlife has executed Lake and Streambed Alteration Agreement EPIMS Notification No. EPIMS-NAP-31256-R3, pursuant to Section 1602 of the Fish and Game Code to the County of Napa.
The project is limited to repairing the existing western wingwall, constructing three new wingwalls and two new traffic barriers on the road deck, installing rock rip-rap within Lower Chiles Creek to reduce scouring and erosion, upgrading and extending the guardrails, installing concrete slabs, and repairing damaged pavement on the existing Chiles Pope Valley Road bridge. If necessary, a cofferdam will be installed on either side of the culvert with a temporary plastic pipe to divert water during construction.
The County previously completed temporary emergency repairs beginning on January 10, 2023 (Emergency Notification EPIMS-NAP-36762) and fully re-opened Chiles Pope Valley Road on January 11, 2023. The emergency repairs resulted in 60 square feet of permanent impacts.
The project will result in 0.02 acre and 23 linear feet of permanent impacts, including the emergency repair work, and 8 square feet and 5 linear feet of temporary impacts, to stream and riparian habitat. No trees will be removed as a result of the project.
