Title

Decker Island Restoration Project

Description

Project is a tidal restoration project proposed by DWR and located in Solano County along the Sacramento River. the project would enhance up to 140 acres of tidal wetland, associated high marsh, and riparian habitats, benefiting special-status species like Delta Smelt (Hypmesus transpacificus) and Chinook Salmon (Oncorhynchus thaleichthys). The project consists of three main elements: lowering a section fo levee, reconfiguring internal berms, and excavating a southern breach. Restoration would be accomplished with minimal in-water work and would utilize biological surveys, work windows, biological monitors, erosion control methods, and construction best management practices to avoid and minimize impacts to physical and biological resources. Project will result in impacts to 22 acres of Giant Garter Snake (Thamnophis gigas; GGS) habitat including temporary impacts to 13 acres; the project will permanently remove 22 acres of GGS habitat. The project is expected to result in incidental take of GGS, which is designated as 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.
