  • Transitions for the Delta Economy

    Transitions for the Delta Economy

    Transitions for the Delta Economy January 2012 Josué Medellín-Azuara, Ellen Hanak, Richard Howitt, and Jay Lund with research support from Molly Ferrell, Katherine Kramer, Michelle Lent, Davin Reed, and Elizabeth Stryjewski Supported with funding from the Watershed Sciences Center, University of California, Davis Summary The Sacramento-San Joaquin Delta consists of some 737,000 acres of low-lying lands and channels at the confluence of the Sacramento and San Joaquin Rivers (Figure S1). This region lies at the very heart of California’s water policy debates, transporting vast flows of water from northern and eastern California to farming and population centers in the western and southern parts of the state. This critical water supply system is threatened by the likelihood that a large earthquake or other natural disaster could inflict catastrophic damage on its fragile levees, sending salt water toward the pumps at its southern edge. In another area of concern, water exports are currently under restriction while regulators and the courts seek to improve conditions for imperiled native fish. Leading policy proposals to address these issues include improvements in land and water management to benefit native species, and the development of a “dual conveyance” system for water exports, in which a new seismically resistant canal or tunnel would convey a portion of water supplies under or around the Delta instead of through the Delta’s channels. This focus on the Delta has caused considerable concern within the Delta itself, where residents and local governments have worried that changes in water supply and environmental management could harm the region’s economy and residents.

Suisun Bay is a dynamic, transitional zone between the freshwater input of the Central Valley rivers and the tidal influence of the upper San Francisco Estuary. This area supports a substantial number of nesting herons and egrets, including three of the largest colonies in the region. Although suburban development is rampant along the nearby Interstate 80 corridor to the north, most of the Suisun Bay area is protected from heavy development by the California Department of Fish and Game and a number of private duck clubs.

The Bay Plan was prepared by the Commission over a three-year period pursuant to the McAteer-Petris Act of 1965 which established the Commission as a temporary agency to prepare an enforceable plan to guide the future protection and use of San Francisco Bay and its shoreline. In 1969, the Legislature acted upon the Commission’s recommendations in the Bay Plan and revised the McAteer-Petris Act by designating the Commission as the agency responsible for maintaining and carrying out the provisions of the Act and the Bay Plan for the protection of the Bay and its great natural resources and the development of the Bay and shore- line to their highest potential with a minimum of Bay fill.

The Delta RMP stakeholder panel kickoff meeting is scheduled for 30 September 2008 and we respectfully request your attendance at the meeting. The meeting will consist of two sessions (see attached draft agenda). During the first session, Water Board staff will provide an overview of the impetus for the Delta RMP and initial planning efforts. The purpose of the first session is to gain management-level stakeholder input and, if possible, endorsement of and commitment to the Delta RMP planning effort. We request that you and your designee attend the first session together. The second session will be a working meeting for the designees to discuss the details of how to proceed with the planning process. A brief discussion of the purpose and background of the project is provided below. In December 2007 and January 2008 the State Water Board, Central Valley Regional Water Board, and San Francisco Bay Regional Water Board (collectively Water Boards) adopted a joint resolution (2007-0079, R5-2007-0161, and R2-2008-0009, respectively) committing the Water Boards to take several actions to protect beneficial uses in the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (Bay-Delta).

Box 808, Marshall, CA 94940 © Heron and egret photographs by Philip Loring Greene (http://www.philiplgreene.com) Audubon Canyon Ranch was founded in 1962 to protect an important heronry on the Marin County coast north of San Francisco and to prevent intensive commercial development of the undisturbed area surrounding the colony. Now, Audubon Canyon Ranch manages a system of wildlife sanctuaries in Marin and Sonoma counties and conducts regional programs in conservation research, habitat protection and restoration, and nature education. The San Francisco Bay Bird Observatory (http://www.sfbbo.org), a collaborator on this project, is dedicated to the conservation of birds and their habitats through science and outreach, and to contributing to informed resource management decisions in the San Francisco Bay Area.
