DARI is the Delta Aquatic Resources Inventory of surface waters, wetlands and other aquatic resources in the Sacramento-San Joaquin Delta (Delta). The goal of the DARI project is to develop a geospatial inventory of aquatic resources that will be used as a common base map for the Delta. A similar mapping approach used to create the California Aquatic Resource Inventory(CARI) will be applied to provide a map of the aquatic resources and their associated attributes.
The Adapting to Rising Tides program of the SF Bay Conservation & Development Commission (ART BCDC), Delta Stewardship Council (DSC) and the San Francisco Estuary Institute / Aquatic Science Center (SFEI) are unveiling the East Contra Costa Shoreline Flood Explorer. SFEI developed the new explorer as a complementary tool to the Bay Shoreline Flood Explorer to allow government organizations and communities in East Contra Costa County to access interactive online maps of local flood risks due to rising sea levels and storm events. These tools help to both highlight what our region could look like without intervention, and to encourage local and regional adaptive plans to minimize flood risks.
San Francisco Bay and its watersheds are polluted by legacy polychlorinated biphenyls (PCBs), resulting in the establishment of a total maximum daily load (TDML) that requires a 90% PCB load reduction from municipal stormwater. Green infrastructure (GI) is a multibenefit solution for stormwater management, potentially addressing the TMDL objectives, but planning and implementing GI cost-effectively to achieve management goals remains a challenge and requires an integrated watershed approach. This study used the nondominated sorting genetic algorithm (NSGA-II) coupled with the Stormwater Management Model (SWMM) to find near-optimal combinations of GIs that maximize PCB load reduction and minimize total relative cost at a watershed scale. The selection and placement of three locally favored GI types (bioretention, infiltration trench, and permeable pavement) were analyzed based on their cost and effectiveness. The results show that between optimal solutions and nonoptimal solutions, the effectiveness in load reduction could vary as much as 30% and the difference in total relative cost could be well over $100 million. Sensitivity analysis of both GI costs and sizing criteria suggest that the assumptions made regarding these parameters greatly influenced the optimal solutions.

This technical memo describes the purpose, functions, and structure associated with the newest addition to the GreenPlan-IT Toolset, the GreenPlan-IT Tracker. It also shares the opportunities for further enhancement and how the tool can operate in concert with existing resources. Furthermore, this memo describes a licensing plan that would permit municipalities to use the tool in an ongoing way that scales to their needs. The memo concludes with a provisional roadmap for the development of future features and technical details describing the tool’s platform and data structures.
Catalyzed by the extensive damages caused by the Winter 2016-2017 storms and the opportunity to align flood response with major habitat improvement, Preparing for the Storm is an innovative public-private partnership to improve watershed health and resilience in the Alameda Creek watershed.
The California Ocean Protection Council (OPC), in close partnership with the State Water Board, has recognized the importance of standard methods for trash monitoring and has funded this project. The Southern California Coastal Water Research Project (SCCWRP) and San Francisco Bay Estuary Institute (SFEI) have partnered up to test multiple trash monitoring methods with a goal of developing a library of methods with known levels of precision, accuracy, and cross-comparability of results, and linking these methods to specific management questions.
The San Francisco Estuary Institute is working to provide support for the San Francisco Bay Conservation and Development Commission (BCDC) though Geographical Information Systems (GIS), Graphics, and Technological Services.
Our projects in the Russian River Watershed help us to understand our past, understand our present, and envision our future. Learn more about what SFEI is doing in partnership with others to advance our scientific understanding of this valuable landscape.
