California Department of Fish and Game U.S. Fish and Wildlife Service Chapter 2. Alternatives These alternatives were screened for their ability to meet the project purpose and need, for technical, logistical, and financial feasibility, and for their ability to avoid or substantially reduce one or more significant impacts of the Project. The result of that screening is that two alternatives, described below, were determined to meet the purposes/objectives and need, be feasible, and to provide a range of environmental impacts and thus constitute a reasonable range of alternatives for NEPA and CEQA evaluation. Five other alternatives were determined to either not meet the purpose and need, not be feasible, or not to provide substantial variation in environmental impacts. These alternatives and the reasons for not considering them are described in detail at the end of this chapter. The No Action Alternative is evaluated as required by CEQA and NEPA. Description of Alternatives Evaluated in Detail Overview Both the action alternatives and the No-Action alternative are described in this section. Each of the action alternatives would affect the same geographical area, and vary primarily in the amount of tidal restoration that would be implemented. Table 2-2 provides an overview of each action alternative’s features. No-Action Alternative Analysis of a No -Action Alternative is required under NEPA and CEQA. This alternative would not involve wetland restoration and enhancement, new trails, or habitat creation; thus, it would not meet the purpose/objectives and need of the. It would also not meet the condition for the grants and other funding for purchase of the project site by SLT. Failure to use the property for the intended purposes would be a breach of contract, a potential violation of the conservation easement, and could require repayment of funds. The CRLF enhancement would likely proceed as a separate project. It is likely that ongoing maintenance would include reduced levels of pumping to control the groundwater level within the project area, and invasive plant control, levee maintenance, and storm water conveyance system operation as feasible. These activities would likely occur at a reduced level due to funding constraints. Mosquito abatement would continue on all portions of the property as required by the Marin-Sonoma Mosquito and Vector Control District (MSMVCD). Mosquito abatement on USFWS property would be conducted in accordance with the Draft Mosquito Management Plan and Environmental Assessment for the San Pablo Bay National Wildlife Refuge (USFWS 2011a) and the Draft San Pablo Bay National Wildlife Refuge Comprehensive Conservation Plan and Environmental Assessment (USFWS 2011b).
