San Francisco Bay Delta

Estuary 2100 Project, Phase 1: Resilient Watersheds for a Changing Climate

Sixteen discrete on-the-ground projects in 4 different program areas:

  • Wetland and Watershed Restoration: remove mercury laden sediment from the Guadalupe watershed (TMDL implementation), develop and pilot water conservation techniques for vineyards, restore riparian and instream habitat to address excessive stream temperatures at Stanley Reach on the Arroyo Mocho, remove- fish passage barriers on Stonybrook Creek, focused efforts on invasive Spartina eradication and initiation of Littorina eradication, use of historical ecology in bayland planning and management processes and restore estuarine habitat in Yosemite Slough, Arrowhead Marsh, Eden Landing and Bahia Marsh.
  • Climate Change: Monitoring Changes in the Bay: produce conceptual adaptive management plans that address climate change effects for wetlands in the Bay Area; analyze vegetation, mudflat, and channel evolution in the South Bay Salt Ponds (SBSP); monitor the changes in mercury bioaccumulation resulting from the SBSP Pond A8 levee breaching; and develop stream restoration design curves for Marin and Sonoma watersheds.
  • LID and Stormwater BMPs: identify and quantify suitable public lands for Alameda County that can be converted from impervious to pervious land cover to manage urban runoff, design and construct a Low Impact Development (LID) pilot project in a low-income San Francisco neighborhood, conduct municipal pesticide reduction trainings and target outreach to reduce urban pesticide use.
  • Public Outreach: work with over fifteen partners to coordinate information on project results and conduct a public outreach campaign.

OUTPUTS (Activities, efforts, and/or work product during project period)

OUTCOMES (Environmental results)

(1-5 yrs)


Control erosion and sediment transport from the 4.3 acre Senador Mine, an abandoned mercury mine in the Guadalupe River watershed, and dispose of calcines on-site to reduce mercury loads to local streams and San Francisco Bay (Santa Clara  County Parks and Recreation, $492,500)

Examine the resilience of Corte Madera Baylands to sea level rise, and consider how their ecosystem benefits can be preserved (Bay Conservation and Development Commission, $591,000)

Develop stream design curves for creeks in Marin and Sonoma counties to aid in stream restoration projects by analyzing the morphology of a statistically significant number of stable streams and plotting bankfull width, height, and sinuosity against drainage area. Establish the correlation between the various channel characteristics and the hydrology of the region (Waterways Resources Institute, $30,000)

Propagate and plant over 12,000 native plants on 10.5 acres to establish upland transition zones adjacent to the existing Bahia tidal wetlands (Marin Audubon Society, $56,000)
