Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 210 Department of Water Resources- 2017 Storm Damage DWR Rehabilitation (SDDR) - Phases 4 and 5 Repair Sites The proposed project would address non-emergency levee erosion repair sites (Phases 4 and 5) identified for repair in 2019 and 2020. This work is a follow on to the 2017 Storm Damage DWR Emergency Rehabilitation Program that rehabilitated emergency levee erosion repair sites (Phases 1 through 3) in 2017 and 2018. The proposed project includes a total of 30 repair sites located in Yolo, Sutter, Tehama, Butte, Colusa, Glenn, San Joaquin, and Sacramento counties. Some of the SDDR projects are located outside of the proposed Study Area but it is possible that some work will occur along the Sacramento River and tributaries and within Sacramento and San Joaquin counties. The proposed project would repair and rehabilitate levees at the 30 locations using a variety of construction equipment, requiring different design considerations based on levee conditions. Construction activities would take place at each site throughout the summer/fall of 2019 or 2020. Each levee repair would require approximately 2 to 4 weeks of active construction and at least three sites would be repaired concurrently, with up to nine sites being repaired at the same time, based on limitations of hauling, air quality permitting, and other potential permit restrictions by responsible agencies. The IS/MND for this project was filed on April 24, 2019. A NOD was filed on August 19, 2019. Department of Water Resources- Sherman and Twitchell Islands Fish Screen Project DWR proposes to place five self-cleaning, retractable fish screen at the waterslide termini of five DWR-owned intake siphons located on Sherman Island and Twitchell Island in order to reduce potential entrainment of Delta Smelt and other fish species by agricultural diversions on state-owned lands. Each installation will require modification of the existing intake siphon to accommodate attachment of the self-cleaning fish screen, construction of a structural steel access walkway, generator-powered winch retrieval track, and additional steel piles to support the structure. This project is located south of Rio Vista along Highway 160 on Sherman and Twitchell Islands in Sacramento County. The IS/MND for this project was filed on March 3, 2016. A NOD was filed on April 15, 2016. Department of Water Resources- Long-Term Operations of the State Water Project (SWP) Under the proposed project, the SWP would continue to be operated to provide flood control and water supply for agricultural, municipal, industrial, recreational, and environmental purposes consistent with applicable legal requirements. SWP operations also would continue to be closely coordinated with the federal Central Valley Project (CVP), including the Coordinated Operating Agreements (COAs) with the US Bureau of Reclamation, and operational requirements from the ongoing re-initiation of Endangered
