Come learn about an exciting report recently completed by the San Francisco Estuary Institute (SFEI) and Sonoma RCD on the historical ecology of the Petaluma River watershed. SFEI will highlight interesting details about the history of this unique watershed and share insights about how historical data can be used to improve future management and conservation decisions. Anyone interested in learning more about the past, present, and future of the Petaluma River is encouraged to attend.

The Flood Control 2.0 project team was presented with an Outstanding Environmental Project Award at the 13^th Biennial State of the Estuary Conference in Oakland, CA. The award is given by the Friends of the San Francisco Estuary to projects that benefit the San Francisco-Bay Delta Estuary and its watersheds.

SFEI and several agency partners recently completed a multi-year, EPA funded project called Flood Control 2.0. The goal of the project was to develop information that is useful for integrating habitat restoration into flood management at the Bay edge. Project outputs are now available at floodcontrol.sfei.org.

The Laguna de Santa Rosa (Laguna) watershed spans 256 square miles and supports a unique complex of biologically diverse ecosystems. Containing the urban centers of Santa Rosa, Sebastopol, Cotati, Rohnert Park, and Windsor, the Laguna watershed encompasses one of the largest floodplains in California. Historically the Laguna watershed supported a diverse ecosystem consisting of oak savanna/vernal pool complexes, riparian forest, emergent and off channel wetlands, and open water.

SFEI recently released a resilient landscape vision for lower Walnut Creek that incorporates habitat restoration actions into flood risk management. The vision, developed in coordination with a team of regional science experts, highlights opportunities for restoring and sustaining vital tidal wetland habitats around lower Walnut Creek while supporting a high level of flood protection under rising San Francisco Bay water levels.

A new report shows how the Tijuana River Valley, which straddles the boundary between Southern California and northern Mexico, looked and functioned prior to the existence of the border wall, the city of Tijuana, and the state of California.

The Tijuana River Valley Historical Ecology Investigation—completed in January 2017—synthesized hundreds of historical maps, photographs, and texts to reconstruct the ecological, hydrological, and geomorphic conditions of the Tijuana River valley prior to major European-American landscape modification.

Flood Control 2.0 is an ambitious regional effort aimed at helping restore stream and wetland habitats, water quality, and shoreline resilience around San Francisco Bay. The project leverages local resources from several forward-looking flood control agencies to redesign major flood control channels so that they provide both future flood conveyance and ecological benefit under a changing climate. This timely project will develop a set of innovative approaches for bringing environmental benefits and cost-savings to flood protection efforts at the mouths of creeks that drain to San Francisco Bay.

SFEI scientists Sean Baumgarten and Scott Dusterhoff will present findings from the Lower Walnut Creek Historical Ecology Study at the Quadrennial Contra Costa County Creek and Watershed Symposium, to be held on December 3, 2015, at the Pleasant Hill Community Center.

SFEI recently released a resilient landscape vision for lower Novato Creek that incorporates habitat restoration actions into flood risk management. The vision, developed in coordination with a team of regional science experts, highlights opportunities for restoring and sustaining vital tidal wetland habitats around lower Novato Creek while supporting a high level of flood protection under rising San Francisco Bay water levels.

SFEI recently completed an historical ecology study of lower Novato Creek in Marin County. The study was conducted as part of the larger Flood Control 2.0 project and was aimed at illustrating the change in creek and bayland habitat conditions over the past 120 years following the installation of flood control levees.
