Flood Control 2.0
This timely project, funded by the US EPA San Francisco Bay Water Quality Improvement Fund, will develop a set of innovative approaches for bringing environmental benefits and cost-savings to flood protection infrastructure along the San Francisco Bay shoreline. The strategy has two complementary approaches that transform costly trapped sediment in local flood control channels into a resource: channel redesign where sufficient adjacent land use flexibility exists, and sediment redistribution for highly constrained channels.
Through an interdisciplinary team linking regional science expertise with on-the-ground flood control agencies, the project will advance channel redesign to restore wetland habitat, water quality, and shoreline resilience through demonstration projects at three creek mouths: San Francisquito, lower Novato, and lower Walnut creeks.
At a region-wide scale, the project will collect and integrate data on coarse sediment and historical stream characteristics with the results of the local projects. The resulting regional strategy will increase environmental benefits and cost-savings to flood protection infrastructure along the San Francisco Bay shoreline.

SediMatch brings together the wetland habitat restoration community and the dredging/sediment supply community with a goal of creating healthy wetland habitats and maximizing beneficial reuse of sediment. In these forums for discussion, challenges and potential solutions for increasing reuse of dredged and excavated sediment at habitat restoration sites are explored. The program aligns with the Long Term Management Strategy for Placement of Dredged Material in the San Francisco Bay Region (LTMS) Program and seeks to implement the recommendations found in the updated Baylands Goals report regarding using dredged and upland sediment to accelerate the rate and scale of wetland restoration through sediment supply augmentation.
In 2011, the SFBJV began tracking the sediment needs of restoration projects and hosted the first match-making meeting between restoration project managers and dredgers at BCDC in 2013.
As a result of that meeting, several “matches” have been made to deliver dredge material for beneficial re-use at restoration sites. A site visit to Cullinan Ranch in late 2014 was an on-the-ground orientation to beneficial reuse. These meetings and site visits, along with subsequent discussions and meetings led by the SFBJV, BCDC, Bay Area Flood Protection Agencies Association, The Bay Planning Coalition and others, have brought together the sediment supply and restoration communities to work towards solutions to the complex challenges keeping us from beneficially reusing sediment at wetland restoration sites.
Flood Control 2.0, is currently providing funding to SFEI, in partnership with the SFBJV and BCDC, to create a Sediment "Match-Up" Online Web Tool and web interface to help match available sediment with opportunities for beneficial re-use. At a broader scale, data collected through the SediMatch data base has the potential to contribute to the understanding of sediment distribution and movement throughout the estuary system, helping scientists better target their research to assist managers with decision making related to current and future conditions. The SediMatch Task Group, comprised of restoration and dredging/sediment supply community members, will develop specific fields for the web interface through joint meetings into 2016. The SediMatch data base is expected to be available on-line in September of 2016.
