ReEnvisioning the Delta

What is the Delta Initiative?

The Delta Initiative is a multi-year research and planning effort at the University of California - Berkeley dealing with the Sacramento-San Joaquin Delta region of California. The fate of the Delta is crucial to California's future -- it is the hub of the state's water supply system, is irreplaceable habitat for migrating birds and fish, and is the route through which critical infrastructure powers the Bay Area's dynamic economy. The Delta is also home to more than half a million people and a large agriculture industry, and is facing dramatic urbanization pressure from the Bay Area, Central Valley and Sacramento housing markets.

The Delta is also at extraordinary risk of disaster. Much of the land in the region has subsided below sea level, and is protected only by an aging system of levees. River floods, earthquakes, and climate change all pose grave threats to the levees, the land, and the state's freshwater supply. A mass failure of the levee system (similar to that which struck New Orleans) could have immense consequences for the economy of the entire state, and even the nation.

The Delta Initiative seeks to understand these pressures and risks, and to explore alternative futures for the Delta that would improve public safety, secure water supply and infrastructure systems, reduce state taxpayer liability, and provide habitat, open-space and recreation benefits.

Before the Flood: Misperception of Flood Risk in the Sacramento-San Joaquin Delta by Jessica Ludy. Demonstrates that residents of a subdivision in the floodplain of the San Joaquin River significantly underestimate the flood risk to which they and their property are exposed.

News Related to the Delta Initiative

Delta Vision completes its work. On December 31, 2008, the Delta Vision Blue Ribbon Task Force sent its final Strategic Plan to the Governor and Legislature of California. The Strategic Plan build upon the Vision for the California Delta that the Task Force issued in October of 2007.

Each of these documents were strongly influenced by the work of the Delta Vision Stakeholder Coordination Group (to which the Delta Initiative made a major contribution -- see below) and the Delta Initiative's report ReEnvisioning the Delta.

Historic floodplain bills: On October 10, 2007, Gov. Arnold Schwarzenegger signed a landmark package of five bills that will greatly improve floodplain planning throughout California, especially in the Delta. Hailed as the biggest political breakthrough in flood management in California in 40 years, the bills will:

Mandate creation of a Central Valley Flood Protection Plan (for the first time in state history) by 2012;

Require local land use plans to conform to the Flood Protection Plan;

Ensure that local governments will bear some liability for levee failures if they approve non-conforming developments;

Establish a 200-year flood protection standard for all new developments in floodplains;

Require the state to create new maps of the 200-year floodplain by 2008; and

Reconstitute and rename the State Reclamation Board.

The Delta Initiative's report "ReEnvisioning the Delta" (see above) was a touchstone in this debate, widely distributed and read in the State Capitol throughout the spring and summer while this landmark legislative action was being formulated. On March 15, 2007, the Delta Initiative conducted a press conference (see press release, prepared remarks and coverage), and testified on the dangers of floodplain development in the Delta (among other topics) to a Joint Committee Hearing of four Senate and Assembly committees.

Delta Vision Stakeholder Coordination Group work hailed: The Delta Vision Stakeholder Coordination Group report, co-authored by the UC-Berkeley Delta Initiative, was effusively praised upon its delivery to the Blue Ribbon Task Force in late August, 2007. Task Force members variously described the work as "stunning," "remarkable" and "brilliant," and strongly praised the stakeholders, staff and consultants for producing the report in under six months.

The report centered on two alternative visions (see below) for the future of the Delta, facilitated by the Delta Initiative in association with the Center for Collaborative Policy at Cal State - Sacramento (CCP). The articulation of these visions, and achievement of consensus among the stakeholders on certain policy recommendations in the report, were viewed as major breakthroughs in California water policy. The visions emerged from a charrette-like workshop conducted by the Delta Initiative and CCP in Courtland, California in June, and subsequent revisions.

Thomas Church Memorial Design Competition (March 2006)
This annual design competition hosted by the Department of Landscape Architecture and Environmental Planning paralleled the Symposium with its 2006 program. Contestants were instructed to re-imagine the California Delta region as a park with local, regional and national appeal.

Advanced Project Design LA204: Water's Edge: Looking Ahead in the California Delta

In the Spring 2006 semester, students reconsidered the boundary between land and water as a means to examine possible futures for the California Delta. They began by analyzing the existing conditions, then developing strategies for individual sites around the region, and finally they examined ways in which those strategies might have implications at a larger scale.
