The US Army Corps of Engineers, Sacramento Division updated wetland and stream maps for the 6 county area (Sacramento, Placer, Yolo, El Dorado, Yuba, and Sutter Counties) to support regulatory, planning, and management efforts in the area. The map was made public in 2011 and was added to EcoAtlas in 2013.

The North Coast WRAMP Demonstation Project focused on mapping and assessing the condition of aquatic resources within the Santa Rosa Plain, CA using GIS based mapping protocols consistent with BAARI. A new regional Mapping Standards Methodology (NCARI) was developed to add regional wetland types not covered in BAARI's documentation.
The Tahoe WRAMP Demonstration Project implemented detailed and standardized mapping protocols within the Tahoe Basin in two watersheds, based on BAARI mapping standards. New region specific mapping methodologies were developed to address region specific wetland types.
Green infrastructure (GI), such as permeable pavement, rain gardens, tree-well planters, or bioswales, can be used as cost-effective, resilient approaches to managing stormwater at its source while delivering environmental, social, and economic benefits for your community. GreenPlan-IT is a versatile open-source toolset that helps aid municipalities with their efforts to plan and evaluate the placement of green infrastructure in the landscape and track the effectiveness of these installations in reducing stormwater run-off, PCB, and mercury in receiving waters.
The Riparian Zone Estimator Tool (RipZET) is a decision support tool developed by the San Francisco Estuary Institute and Aquatic Science Center for the California Riparian Habitat Joint Venture and the California Water Resources Control Board to assist in the visualization and characterization of riparian areas in the watershed context.
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.
Web services provide a standard way to access geo-referenced data online. Although potential uses are numerous, typically web services allow one machine to exchange data with another for timely, automated, and efficient sharing of information. Different service types provide different levels of access to the data, including serving image tiles of the data or the features and attributes themselves.
