Title: Final Environmental Impact Statement/Final Environmental Impact Report on the American River Watershed Common Features Project/Natomas Post-authorization Change Report/Natomas Levee Improvement Program, Phase 4b Landside Improvements Project
Authors: United States. Army. Corps of Engineers. Sacramento District; Sacramento Area Flood Control Agency; California. Central Valley Flood Protection Board; United States. Federal Aviation Administration
Abstract: This final environmental impact statement/final environmental impact report (FEIS/FEIR) has been prepared by USACE and SAFCA in accordance with the requirements of the National Environmental Policy Act (NEPA) and the California Environmental Quality Act (CEQA), respectively, to respond to comments received during the agency and public review period for the draft environmental impact statement/draft environmental impact report (DEIS/DEIR) and to present corrections, revisions, and other clarifications to the DEIS/DEIR. The FEIS/FEIR evaluates the significant environmental impacts of the Phase 4b Landside Improvements Project (Phase 4b Project), and will be submitted to Congress in late 2010 to support approval of USACE’s American River Watershed Common Features Project/Natomas Post-authorization Change Report (Common Features/Natomas PACR), which is an element of the American River Watershed Common Features Project General Reevaluation Report (Common Features GRR). The Common Features/Natomas PACR includes all four project phases (1, 2, 3, and 4a and 4b) of the Landside Improvements Project, which is a component of SAFCA’s Natomas Levee Improvement Program (NLIP). The overall purpose of the NLIP is to bring the entire 42-mile Natomas Basin perimeter levee system into compliance with applicable Federal and state standards for levees protecting urban areas. The Phase 4b Project is the final phase of the Landside Improvements Project, and consists of improvements to the remaining portions of the Natomas Basin’s perimeter levee system in the City of Sacramento and in Sutter and Sacramento Counties, California, associated landscape and irrigation/drainage infrastructure modifications, and habitat creation and management. If the Common Features/Natomas PACR is authorized by Congress, USACE would implement the Phase 4b Project. In the event that USACE does not receive authorization to construct the Phase 4b Project, SAFCA could choose to implement the Phase 4b Project. In readiness for the latter scenario, SAFCA is requesting permission from USACE pursuant to Section 14 of the Rivers and Harbors Act of 1899 (33 United States Code [USC] Section 408, referred to as “Section 408”) for alteration of Federal project levees; Section 404 of the Clean Water Act (33 USC Section 1344, hereinafter referred to as “Section 404”) for placement of fill in jurisdictional waters of the United States; and Section 10 of the Rivers and Harbors Act of 1899 (33 USC Section 403, referred to as “Section 10”) for work performed in, over, or under navigable waters of the United States. This FEIS/FEIR covers the requested permissions from USACE, if needed. The FAA is serving as a cooperating agency under NEPA because if USACE and SAFCA select an alternative that requires the Sacramento International Airport to seek a release from Federal Airport Improvement Grant assurances, the FAA would use this FEIS/FEIR in exercising its decision-making authority under 49 USC Section 47107 regarding whether to approve those actions. The CVFPB is serving as a non-Federal sponsor of USACE’s Common Features/Natomas PACR, and is concerned about integrating overall flood damage reduction in Sacramento. This FEIS/FEIR summarizes prior environmental analyses for all previously approved project phases of the Landside Improvements Project––including alternatives previously considered, analyzed, and rejected from further consideration––and evaluates in detail the environmental effects of the Phase 4b Project (Proposed Action), including alternatives to the Phase 4b Project. The Proposed Action would result in significant and unavoidable adverse impacts on agricultural resources; land use, socioeconomics, and population and housing; biological resources; cultural resources; transportation and circulation; noise; recreation; visual resources; and hazards and hazardous materials.

Title: Supplemental Environmental Assessment : Isabella Lake Dam Safety Modification Project, Dam and Spillway Design Refinements : Kern County, California
Authors: United States. Army. Corps of Engineers. Sacramento District; Sequoia National Forest (Agency : U.S.)
Abstract: Pursuant to the National Environmental Policy Act of 1969 (NEPA), as amended, this Dams and Spillway Design Refinements Supplemental Environmental Assessment (SEA) identifies and analyzes any additional beneficial or adverse potential effects that would result from the proposed design refinements to the Isabella Lake Dam Safety Modification (DSM) Project. The U.S. Army Corps of Engineers (USACE), Sacramento District, is the lead agency and the United States Department of Agriculture Forest Service, Sequoia National Forest (USFS) is a cooperating agency. The Isabella Lake DSM Project was previously evaluated under NEPA in the Isabella Lake DSM Project Draft Environmental Impact Statement (DEIS) of March 2012, and a Final Environmental Impact Statement (FEIS) of the same title in October 2012. The DEIS described and assessed impacts of the Isabella Lake DSM Project. A Record of Decision (ROD) was issued by USACE on December 18, 2012. Several design elements were identified in the FEIS, as well as in subsequent tiered NEPA documents, that called for further refinement and clarification as additional project details were developed. This SEA provides an assessment of the proposed design refinements that were identified to best accomplish the Isabella DSM Project. Two alternatives are assessed within this document, the No Action Alternative and Alternative 2, the Proposed Action. The Proposed Action best fulfills the purpose and need of the Project.

Title: American River Watershed, California, Folsom Dam Raise Project : Updated Designs : Final Supplemental Environmental Impact Statement/Environmental Impact Report
Authors: United States. Army. Corps of Engineers. Sacramento District; United States. Bureau of Reclamation; California. Department of Water Resources; California. Central Valley Flood Protection Board; Sacramento Area Flood Control Agency
Abstract: USACE and its non-Federal sponsors, the CVFPB, and the Sacramento Area Flood Control Agency (SAFCA), propose to provide enhanced flood risk protection to the Sacramento metropolitan area by constructing the Folsom Dam Raise Project (Project), a separable element of the American River Watershed, California Project (Authorized Project). This flood risk management project is located in Sacramento, Placer, and El Dorado Counties in California. Alternative 2 is the Preferred Alternative for the Project. The Preferred Alternative will involve: (1) constructing a new Dike 3; (2) modified concrete floodwall elements; (3) onsite borrow and disposal at the Mormon Island Auxiliary Dam (MIAD) West; (4) rock crushing operations at MIAD East; (5) a Project mitigation plan; and (6) smaller scale actions. This American River Watershed, California Folsom Dam Raise Project: Updated Designs Final Supplemental Environmental Impact Statement/Environmental Impact Report (SEIS/EIR) is a supplement to the Folsom Dam Raise Project Final Supplemental Environmental Impact Statement/ Environmental Impact Report (SEIS/EIR) dated October 2017 and prepared by USACE (USACE, 2017). The 2017 SEIS/EIR was a supplement to the Folsom Dam Safety and Flood Damage Reduction Final Environmental Impact Statement/Environmental Impact Report dated March 2007 (Reclamation, 2007) prepared by the Bureau of Reclamation. The Preferred Alternative includes refinements to the designs analyzed in the 2017 SEIS/EIR. This SEIS/EIR was prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended, and the California Environmental Quality Act (CEQA) of 1970, and provides an evaluation of the potential effects on environmental resources that could occur if the Preferred Alternative is constructed, and those that could occur if the Project is not constructed with these refinements (Alternative 1, No Action). It also identifies measures to avoid, minimize, mitigate, and/or compensate for any potentially significant adverse impacts, where feasible.
