Adapting to Rising Tides: East Contra Costa Shoreline Flood Explorer (Project)
As a continuation of our collaboration with BCDC and the Adapting to Rising Tides (ART) team, the technical team at SFEI has developed a new version of the sea-level rise visualization tool which focuses on East Contra Costa and the Delta. The East Contra Costa Shoreline Flood Explorer incorporates regionally specific data that takes into account inundation and flooding information as a product of riverine flooding and sea-level rise. The map visualizes these data in conjunction with storm events and makes it available to the public, businesses, and policymakers so that they can assess and prepare for potential impacts to communities.
Adapting to Rising Tides: Bay Shoreline Flood Explorer (Project)
SFEI’s Environmental Informatics team has designed and developed the Bay Area Flood Explorer for the Bay Conservation and Development Commission's (BCDC) Adapting to Rising Tides (ART) program. The project is designed to highlight threats posed by sea level rise. The map displays sea-level-rise data created by AECOM, which was developed with support from the Metropolitan Transportation Commission, the Bay Area Toll Authority, and the greenhouse gas reduction funds.

New Interactive Map Helps Delta Governments and Communities Plan for Adaptation by Understanding Flood Risks from Rising Sea Level and Storms (News)
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.

Safe to Eat Portal (Project)
Fish and shellfish are nutritious and good for you to eat. But some fish and shellfish may take in toxic chemicals from the water they live in and the food they eat. Some of these chemicals build up in the fish and shellfish - and in the humans that eat fish and shellfish - over time. Although the chemical levels are usually low, it is a good idea to learn about advisories and monitoring in water bodies where you fish, and for fish or shellfish you eat.
Project Tracker assists with regional reporting (News)
More and more groups rely on Project Tracker to assist with their reporting. Why? Because Project Tracker standardizes project data across programs so it is easier to summarize information for reporting purposes. Especially in the Bay Area, it is the most comprehensive regional dataset for project information.
