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.
The Clean Watersheds For A Clean Bay project is multi-year project focused on implementing the PCBs and mercury Total Maximum Daily Load (TMDL) water quality restoration programs, and is the next step in the effort to reduce loading of sediment-bound pollutants to the Bay. Funded by the USEPA, BASMAA, and 6 six of the Bay Area countywide stormwater management agencies, this project is evaluating control options to reduce mass loadings of PCBs, Hg and other pollutants from urban stormwater runoff to the San Francisco Bay.
The Regional Monitoring Program for Water Quality in San Francisco Bay is an innovative collaboration of the San Francisco Bay Regional Water Quality Control Board, the regulated discharger community, and the San Francisco Estuary Institute. It provides water quality regulators with the information they need to manage the Bay effectively. The RMP produces two types of summary reports: The Pulse of the Bay and the RMP Update. The Pulse focuses on Bay water quality and summarizes information from all sources.
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.
Nonpoint source pollution has been identified nationally, in the State of California, and in the Bay Area as the leading source of degradation of natural waters. The magnitude of nonpoint source pollution is accentuated in coastal areas where human population is high and where pressures from urban development, industrial and commercial activities, and recreational use are the greatest. San Francisco Bay is listed as an impaired water body for PCBs and mercury under Section 303(d) of the federal Clean Water Act . The RWQCB has recently developed Total Maximum Daily Load (TMDL) reports for the Bay for mercury and PCBs.
