Site work for a development in American Canyon, California. Conceptual plans call for site work for a development.

The project consists of completing technical studies to document the project site's baseline conditions; preparing 30% and 60% design documents for restoration and public access; preparing California Environmental Quality Act (CEQA) documentation; preparing permit application drafts; and performing community engagement and Tribal outreach. The design documents will propose features that restore full tidal exchange, restore 60 acres of shoreline habitat, raise 1.2 miles of the Bay Trail, enhance 18 or more acres of transitional ecotone habitat, build a kayak launch, and create a half mile of new trails. The design is intended to have the following outcomes if it were to be advanced to construction under future actions beyond the scope of this agreement: - Replace the undersized culverts where North Slough crosses the Bay Trail with a larger box culvert or bridge, enhancing 41 acres of tidal marsh and bay flat (North Slough Pond) habitat by restoring full tidal exchange; - Provide fish passage for federal and state protected species like Central California Coast steelhead and North American green sturgeon Southern distinct population segment; - Improve public safety and accessibility along the Bay Trail and North Slough; - Raise 1.2 miles of Bay Trail around North Slough Pond to increase resilience to sea level rise and block flood-related landfill impacts; - Re-establish 0.2 acres of tidal marsh and 0.75 acres of transitional habitat at 205 Wetlands Edge, including a vegetated swale for water quality improvement; - Enhance at least 18 acres of transitional habitat with native vegetation and weed management; - Design a kayak launch, 0.5 miles of new public access trails, shared parking, and restrooms next to the 205 Wetlands Edge soon-to-be-built Napa River Ecology Center. Future additional work, such as the 90% and 100% drawings, designs for utilities and parking lot security lighting, permit application submittal, bid documents, and construction implementation, are not part of the current project.
