Soil Investigations for Data Collection in the Delta Initial Study/Proposed Mitigated Negative Declaration 209 3.21.2.6 Climate Change Global warming and climate change is an issue that has become more prominent over the past decade and one that certainly warrants consideration in the long-run. It has been predicted that global warming will increase Central Valley ambient air temperatures by 2°C to 7°C by the end of this century. Such an increase is anticipated to have a profound effect on Central Valley run-off and local hydrology. Within the Delta, anticipated effects are expected to include changes in seasonal flow patterns and increased water levels (as a result of general sea level rise). While difficult to predict, it is anticipated that such events will affect the distribution, and possibly even the abundance, of many aquatic species currently occupying the Delta seasonally or year- round. 3.21.2.7 Projects Department of Water Resources- Lookout Slough The Lookout Slough Tidal Habitat Restoration and Flood Improvement Project is proposed to help satisfy DWR’s obligation to restore 8,000 acres of tidal marsh per the 2008 United States Fish and Wildlife Service (USFWS) Biological Opinion (BiOp) and the 2009 National Marine Fisheries Service (NMFS) BiOp, and to increase flood storage and conveyance, increase the resiliency of levees, and reduce flood risk within the Yolo Bypass. The proposed project site would be located in to the south of Duck Slough, to the west of Shag Slough, to the east of Cache Slough and to the south of Liberty Island Road. The propose project would be located near the Liberty Island Ecological Reserve, Liberty Island Conservation Bank, and Little Hastings Island Conservation Bank. An Environmental Impact Statement/Environmental Impact Report (EIS/EIR) for this project is currently under development. Department of Water Resources- Prospect Island Tidal Habitat Restoration Project This project proposes to restore tidal action to 1,528 acres on the currently flooded Prospect Island in the Sacramento River Delta to improve productivity for Delta Smelt and salmonid species. This tidal habitat restoration project is located in Solano County. Project activities include clearing and invasive species control; excavation of tidal slough channels; removal of a portion of an internal cross levee; placement of excavated soils into remnant agricultural ditches and newly constructed berms and benches; dredging of the spur channel between Miner Slough and the southern portion of the site; limited planting and revegetation; and excavation of two levee breaches to establish tidal connectivity with Miner Slough. The EIR for this project was filed on March 1, 2019. A NOD was filed on August 19, 2019.
