AI Contract Overview

The Wall Road Landslide Repair Project (RDS26-38) is a forecast infrastructure project managed by Napa County, California, to address roadway damage caused by intense rainfall during the 2025-2026 winter season. The primary scope of work focuses on repairing an 88-foot landslide at 550 Wall Road and a secondary smaller damaged location further north. Technical requirements include the construction of a concrete retaining wall with heights ranging from 4 to 8 feet, utilizing cast-in-drilled hole piles spaced at 6 feet on center. The project also requires filling and repaving the roadway to restore the asphalt surface and pre-slide drainage patterns. To maintain the integrity and potential historic significance of the area, the project will not change the road alignment or create visual or audible changes to the landscape. Environmental protections are a priority, with the project being categorically exempt under CEQA Sections 15301 and 15302. Key constraints include a strict prohibition on tree removal and the requirement to hydro seed disturbed areas with a native grass mix upon completion. The contractor must implement Best Management Practices and erosion control measures to protect cultural resources and potential special-status species within the project area.

Full Description

Damage occurred at 550 Wall Rd as a result of storm events in Napa County during the 2025-2026 winter season. Intense rainfall saturated the roadway resulting in a landslide approximately 88 feet in length. A secondary, smaller location further north, was damaged previously and will be included in the repair. The proposed repair for the 550 Wall Rd slides include construction of a concrete retaining wall where significant settlement and damage occurred. The cast-in-drilled hole piles are spaced at 6 feet on center. Filling and repaving the roadway will be required to restore the asphalt surface and pre-slide drainage patterns. The wall height varies from 4-8 feet in height. Although repair work will be conducted within the boundaries of Wall Road, the Project does not propose to change the alignment or create visual or audible changes to the landscape, maintaining the integrity of the road and its ability to convey its potential historic significance. While some vegetation will be impacted by the Project, no trees will be removed. After completion of work the disturbed area will be hydro seeded with native mix of grasses. Best Management Practices and erosion control will be implemented, as well as environmental commitments to protect environmental resources, including any potential special-status species or cultural resources that may occur in the project area.
