Creek Restoration

Green Gulch Creek Restoration

Green Gulch Creek runs the length of Green Gulch, and is the closest tributary of Redwood Creek to the Pacific Ocean.  In the winter of 2004/2005 Coho Salmon were spotted in the portion of the creek adjacent to the “farm shed,” in Green Gulch’s “second field.”  The following year one thousand baby Cohos were counted, by wildlife biologist Darren Fong (the product of one spawning pair).  This discovery galvanized the Green Gulch community to put resources into restoring the creek.  With generous support from the Marin Community Foundation and the California Department of Fish and Wildlife, Green Gulch hired and partnered with the environmental restoration firm, Prunuske Chatham Inc., to design an enhanced creek habitat the length of the farm and garden (up to the “Zendo Pond,” at this point an insurmountable fish barrier), which will restore native riparian habitat for many species, widen floodplain, and provide refuge for juvenile Coho Salmon.

This summer, with grants from The NOAA Fisheries Program, California Department of Fish and Wildlife, the County of Marin, Natural Resources Conservation Service (USDA), and many generous donors to Zen Center, we will begin phase 1 of the design (which began last fall with the building of a new road): a large meander in one of Green Gulch’s bottom fields, including a new emergency vehicle and pedestrian bridge which will accommodate hundred year storm flows.

Next summer, we will complete this phase by creating a new above ground channel to deliver water and much needed spawning gravels from Spring Valley creek directly to Green Gulch creek (it currently empties into one of Green Gulch Farm’s irrigation ponds, starving the creek of sediment and gravel).

The benchmarks for this phase of the project include:

  • Installing 4000 native plants.  Mixture of sedges, rushes, ferns, shrubs, and trees.
  • Creating 700 linear feet of meandering natural channel to replace 450 feet of narrow straightened channel
  • Creating 1.5 acre of floodplain wetland and riparian habitat
  • Installing 30 redwood logs and 37 redwood rootwads to create instream summer rearing and winter refugia habitat for coho salmon and steelhead trout
  • Installing at least 350 linear feet of biotechnical bank stabilization, including brush mattresses, willow wattles, and fabric reinforced earth fills.

Planting Plan for the meander reach, to be completed in December of 2014

Planting Plan for the “Spring Valley Bypass” channel through the upper Green Gulch gardens, to be completed in 2015

This project will cost over to $1.5 million dollars.  We have raised a great deal of this, but are still $440,000 short of our goal ($160k for the meander reach to be completed in 2014, and $280k to restore connectivity between Green Gulch Creek and Spring Valley, which will hopefully happen in 2015).  If you would like to join the many public agencies and Sangha members that are supporting this project for the benefit of both the human and the more-than-human world, please click here, or contact the San Francisco Zen Center development department (asstdevdirector@sfzc.org or 415-354-0354)
