Watershed Study Goals

Rehabilitate natural processes within the San Pablo Bay watershed system.

Protect existing high quality habitat throughout the watershed.

Restore degraded habitat to high quality ecological and hydrologic function.

Sustain a healthy community of native species. Improve and maintain water quality and in-stream flow. Prevent the establishment of new non-native species,

and curb the expansion of existing non-native species.

On Significance…

“The San Pablo Bay watershed is part of the San Francisco Bay-Delta Estuary, one of the largest estuaries in North America. The Estuary includes San Francisco Bay, San Pablo Bay, Suisun Bay and Sacramento-San Joaquin Delta. The Estuary watershed drains more than 40 percent of California’s surface area. The Estuary is one of the most important ecological units on the west coast of North America, and certainly the most ecologically valuable estuary in California. San Pablo Bay lies between the less salty Suisun Bay and the saltier San Francisco Bay. The extreme importance of this area ecologically is highlighted by the pressure for development that this area also receives. Close to San Francisco, Vallejo, Richmond, Napa, Novato, Petaluma, Pinole, and other growing urban areas, the San Francisco Bay area and North Bay counties are centers for growth and prosperity, which can put added pressure for development on ecologically sensitive and rare places.”

“While all of the value inherent in ecosystems cannot necessarily be measured in economic terms, it is useful for project proponents to demonstrate that the value of the project’s benefits exceeds the cost of achieving those benefits. Project proponents should consider carefully how their proposed actions will help meet Program objectives, what the environmental and social benefits of their projects are, and what kind of investments will be required to produce their desired outputs. For accepted projects to be funded by the USACE, detailed cost benefit and incremental cost analyses will be required. While the USACE can offer assistance in formulating these detailed analyses, it is important for project proponents to have a qualitative understanding of the costs and benefits of their proposed actions from project inception forward. Project proponents should also develop an understanding of the risks and uncertainties associated with expected project outcomes. Guidance on these concepts is provided in the USACE document ER 1105-2-100 (USACE 2000c).”

WRDA 2007, Sec 5053“The Secretary may participate in

critical restoration projects that will produce, consistent with Federal programs, projects, and activities, immediate and substantial ecosystem restoration, preservation, and protection benefits in the following sub-watersheds..:”

A) The tidal areas of the Petaluma River, Napa-Sonoma Marsh

B) The shoreline of West Contra Costa County

C) Novato CreekD) Suisun MarshE) Gallinas-Miller CreekTypes of Assistance Authorized:

planning, design, constructionLimit: $40 million

Where We’re At Now… Potential $500,000 in President’s Budget Identify two or three initial projects for technical planning

and design assistance► Projects should be identified in WRDA 2007, Section 5053.► Projects should have an identified non-Federal Sponsor with

money to cost share.► Projects should claim only a portion of the $40 million cumulative

budget provided in Section 5053.► Projects should reflect a range of geographic diversity in the

watershed.► Projects should be at an appropriate state of readiness.

May be able to use Section 5053 construction authority Regional approach has been successful Continued collaboration
