This Issue Paper, authored by Jessica Davenport, the Council's Program Manager for Ecosystem Restoration and Land Use, is entitled Restoring Habitat with Science and Society in Mind. The purpose of the 22-page paper is to survey restoration activities in the Delta; describe the needs, progress and opportunities related to restoration; and propose key areas of focus for the Delta Stewardship Council and other agencies to advance habitat restoration.
Some of the areas of focus for Council staff for the next two years include:
Continue to provide early consultation on habitat restoration projects that are Covered Actions under the Delta Plan in order to advise project proponents on using best available science and adaptive management and avoiding or reducing conflicts with existing uses, where feasible.
Report on habitat performance measures by December 2014 and again in December 2015.
Work with others to complete at least one of the landscape-scale conceptual models and associated landscape habitat metrics for the priority habitat restoration areas.
Enagage Delta Plan Interagency Implementation Committee members in discussions of challenges and potential solutions related to land acquistion and permit coordination.

Covering only about 1 percent of California’s area, the Sacramento-San Joaquin Delta, including Suisun Bay and Marsh (hereafter referred to as Delta-Suisun), contributes much more to the state and nation than one might expect from its small size.
The Delta-Suisun provides a set of environmental and economic services whose benefits extend well beyond its borders. To help people gain a common understanding of these services, this report provides an overview of the existing status of these services and a perspective about how these services may change in the future.
This report was prepared to highlight observations and to present a common understanding about the status and trends of key Delta-Suisun services. The Delta Risk Management Strategy (DRMS) is considering these observations while conducting a risk assessment for the Delta-Suisun and will report on its findings in spring 2007.
Having a common understanding of the area’s services will benefit ongoing and new Delta-Suisun studies and initiatives. Information in this report will be considered by members of the Delta Vision Blue Ribbon Task Force and Stakeholder Coordination Group as they begin work on the Delta Vision and Strategic Plan.

Resolution of the Delta’s water supply, water quality, and fish problems may involve building various structures, possibly including gates, pumps, canals, levees, and dams, and undertaking landscaping rearrangements to improve habitat for several species of flora and fauna. Resolution also involves changing water flow regimes in ways that would make more or less water, but probably less, available for human uses. This work and these changes will cost serious money. Cost estimates for many of these actions have not yet been developed.
This paper explores approaches to financing these “improvements” and “mitigations.” While a little abstract, this is abstraction that matters. It will determine from whose pockets a good deal of money will come.
California has a long history of financing water projects. The first section of this paper reviews this history, in hopes of identifying water-financing principles that might be adapted to Delta improvements and mitigation. Some deep-seated controversies about how Delta improvements should be financed have roots in this history, and it may be helpful to point them out.
A core idea in California’s approach to financing water projects is that beneficiaries should pay for them. Decades ago, this was a straightforward proposition – people or water districts should pay for the necessary dams, canals, and pumps and the costs of operating them in proportion to the amount of water they received. In the current age of rising environmental sensitivity, it is a little muddier. An alternative formulation that applies, at least crudely, to housing developments and highway projects, is that project proponents should pay to mitigate at least some of the environmental harm that their project is likely to cause. The second section of this paper explores this controversial subject. It seems unlikely that any consensus can be reached about how to finance facilities in the Delta without reaching some agreement about how to deal with this matter.
This paper was first issued in July, 2008. This version contains a few clarifications made in response to the Blue Ribbon Task Force’s reviewers. The author is grateful for their suggestions.

A vast watershed connects the mountain streams surrounding California’s Central Valley with San Francisco Bay and the ocean beyond. Over the course of the last two centuries, much of the natural productivity, biodiversity and ecological integrity of the watershed has been destroyed by modifying the environment without fully understanding the long-term environmental consequences. Long the site of some of the nation’s most intensive conflicts over the use of land and water resources, this system is now emerging as the focus of one of the most ambitious ecological restoration efforts ever undertaken in the United States.
This report was designed to provide a coherent and defensible ecological framework and information base for restoration. The need for such an historical, broad-scale perspective on system ecology stems from two fundamental principles of ecological restoration - the need to manage toward a natural template and to manage at ecosystem and landscape levels.
