SFEI completed a pilot study focused on creating a framework for a rapid protocol that can be used to delineate the current and future head of tide zone for San Francisco Bay tributaries using both “desktop” and field investigations.

Using a systematic, empirical, and repeatable approach, we mapped the location of the shorelines in San Pablo Bay at three points in time: 1855, 1993, and 2010. We then measured rates of change over the long (1855-1993) and short-term (1993-2010) to identify zones of erosion, progradation, and areas that have remained stable.

With California's drought rapidly changing the outlook for natural resources, decision-makers must be equipped with information and tools that facilitate clear and rapid decisions. The proposed grant would fund the standardization, visualization, and sharing of Level 3 data. 

SFEI is developing an online interactive map to support regional planning and assessment given accelerated sea level rise around the Bay.
