The Delta Initiatives Matrix is a tool developed by the Corps to assist in tracking the multiple ongoing planning efforts in the Delta.  The matrix lists projects and studies that could have a direct or indirect influence to Corps initiatives, as well as pertinent references and resources.  This product is a living document that is frequently updated to reflect new and changing information.

Levee Stability Program

Collapse All Expand All
Click here to expand contentClick here to collapse content  Project Purpose

The CALFED Act (PL 108-361) directed the U.S. Army Corps of Engineers (USACE) to deliver a report that identified and prioritized potential levee stability projects in the Delta that could be carried out with the authorized $90 million in Federal funds. An additional $106 million was authorized to be appropriated by Section 3015 of WRDA 2007.

To quickly identify critically needed projects with active non-Federal support, the USACE invited Delta stakeholders to submit project proposals with letters stating their willingness to participate as cost-sharing sponsors. In response, Delta area Reclamation Districts and flood management agencies submitted 68 project proposals totaling more than $1 billion in estimated costs. USACE evaluated proposals and prioritized potential projects according to how well they met USACE environmental, economic, and other implementation criteria.

The USACE short-term strategy is to move quickly to construction on high priority levee reconstruction projects identified in that report. The authorized $196 million of Federal funds, plus the required non-Federal funds, would be an important first step to address Delta-wide levee system needs. The long-term strategy will be developed through the Delta Islands and Levees Feasibility Study process. The project delivery process includes: PMP/FCSA development; Project Implementation Report (PIR); SPD approval; Project Partnership Agreement (PPA) execution; design & construct; and operate & maintain.

Delta Islands & Levees Feasibility Study

Collapse All Expand All
Click here to expand contentClick here to collapse content  Study Purpose

This feasibility study is the Corps’ mechanism to participate in a cost-shared solution to a variety of water resources needs for which we have the authority. Results of the Department of Water Resourcess' (DWR) Delta Risk Management Strategy (DRMS) studies will be used to define problems, opportunities, and specific planning objectives.

The feasibility study will address flood risk management, ecosystem restoration, water quality, water supply, and a variety of other issues. A feasibility cost-sharing agreement (FCSA) was executed May 26, 2006 with DWR, our non-Federal sponsor.

The total cost of the feasibility study is currently $12,000,000; cost shared 50/50 with the California Department of Water Resources.

FY 08 appropriations at $859,000

FY 09 appropriations at $478,000
  -Reprogrammed additional $150,000

Program Overview

The Sacramento-San Joaquin Delta has a vital and highly complex role in the California ecosystem. Covering nearly 1100 square miles, the Delta is composed of a delicate latticework of streams, marshes and estuaries that act as a reservoir and a natural water filtration system. Water from the Delta system supplies drinking water for much of California and some of the most productive farm land in the nation.

The U.S. Army Corps of Engineers shares responsibility in this complex issue with a host of local, state and other Federal stakeholders.

The Delta is formed by the confluence of the state’s two largest rivers: the Sacramento flowing south from its headwaters near Mt. Shasta and the San Joaquin flowing north from its origins high in the southern Sierra Nevada.

Joining the Sacramento and the San Joaquin are the Mokelumne and the Cosumnes rivers, that comprise the Delta’s watershed, draining nearly 50 percent of the state’s runoff. Through a maze of 57 man-made leveed islands and tracks, these waters of the Delta flow westward.

Pumping stations move a portion of this water throughout the state: the State Water Project, the federal Central Valley Project, Contra Costa Canal, North Bay Aqueduct, City of Vallejo diversion and the Western Delta Industry diversion. The remainder of Delta water flows to farms and communities within the Delta, and then out to sea through a series of bays.
