The plan specifically targets habitat and management improvements to benefit coho salmon at a range of lifestages. The San Geronimo Golf Course (SGGC) is situated in the headwaters of the Lagunitas Creek Watershed. San Geronimo Creek and Larsen Creek flow through the Golf Course. These two creeks are part of a larger riparian assemblage extending to Tomales Bay that primarily supports coho salmon, steelhead trout, and to a lesser extent Chinook salmon. The golf course is one of the largest parcels of land adjacent to San Geronimo Creek within the San Geronimo Valley and salmonids actively use the creeks for spawning and rearing throughout the year. This makes the golf course highly suitable for development and implementation of restoration and management strategies that can have a significant benefit to salmonids. The residents and community of the San Geronimo Valley are deeply engaged and invested in improving the quality of habitat for coho and increasing likelihood for successful recovery of the species. This is a guidance document developed specifically for the SGGC, to benefit of coho salmon and steelhead trout, in the context of the greater San Geronimo Valley watershed and community. This study was undertaken as part of a grant from the California Department of Fish and Wildlife (CDFW), obtained by the Salmon Protection AND Watershed Network (SPAWN). SPAWN is a community-based non-profit organization located in western Marin County that formed in 1996 as an effort to increase public support and funding for salmonid habitat restoration and protection projects within the Lagunitas Creek watershed. Over the years SPAWN has worked to create partnerships with public agencies and private property owners to protect and restore salmonid habitat, with the SGGC being one such partner. SPAWN and the past and current owners of the SGGC have worked together on previous habitat improvement projects including invasive plant removal, enhanced fish passage, floodplain restoration, bank stabilization, and in-stream habitat enhancements (LWD). This study furthers this previous work by developing a site scale restoration and management plan for the golf course aimed at improving conditions for salmonids at the golf course and within the greater watershed. The overall project goals related to golf course’s role in salmonid recovery include: Directly improve coho salmon habitat, instream structure and riparian habitat Improve stormwater quality and manage peak flows Coho-Friendly Habitat and Operations Plan 1-1 D121008.00 San Geronimo Golf Course June 2014 FINAL 1. Introduction Improve golf course operations and management (water use, integrated pest management, and invasive species management) The existing habitat conditions, management and treatment of stormwater, management and use of water for irrigation are three components that are central to developing a holistic management plan for the SGGC that will benefit salmonids.

Sleepy Hollow Homeowners Association May 3, 2013 Board of Supervisors of Marin County 3501 Civil Center Drive San Rafael, CA 94903-4157 Re: Stream Conservation Area (SCA) Proposed Amendments to the Development Code Honorable Members of the Board of Supervisors: INTRODUCTION The Sleepy Hollow Homes Association (SHHA) objects to the proposed changes to Chapters 22.33 (Stream Protection) and 22.63 (Stream Conservation Area Permit) as they would apply to the residents of the unincorporated portion of San Anselmo known as Sleepy Hollow. We ask that the County exempt and/or delay implementation of any changes to Chapters 22.33 and 22.63 as to the city-centered corridor streams, including Sleepy Hollow. The SHHA supports implementation of the proposed amendments to the San Geronimo Valley, to protect wildlife habitat in streams where Coho Salmon currently exist. The SHHA supports regulations to ensure the health and survival of the species in these areas. The SHHA recognizes the urgency of this matter to the San Geronimo Valley, both for the survival of the endangered and declining Coho population and for the property rights of the affected residents who are currently subject to a building moratorium.

  • Evidence of Streamflow and Sediment Effects on Juvenile Coho and Benthic Macroinvertebrates of Lagunitas Creek and San Geronimo Creek, Marin County, California
    Evidence of Streamflow and Sediment Effects on Juvenile Coho and Benthic Macroinvertebrates of Lagunitas Creek and San Geronimo Creek, Marin County, California Hydrology for Planners, LA 222 UC Berkeley May 18, 2009 Joanie Ball [email protected] Sibyl Diver [email protected] Jason Hwan [email protected] ABSTRACT Lagunitas Creek and San Geronimo Creek in Marin County, California provide some of the best habitat for endangered coho salmon ( Oncorhynchus kisutch ) in the southern part of their range, making it a priority for local and federal agencies to collect habitat and biological data throughout the watershed. For this paper, we synthesized numerous years of existing data, including flow, sediment conditions, endangered coho salmon densities, and one year (2001) of macroinvertebrate biological assessment data to investigate biotic and abiotic interactions among physical habitat, juvenile coho, and macroinvertebrates. We found that summer juvenile coho densities in Lagunitas Creek were negatively correlated with annual peak mean daily flow, whereas in San Geronimo Creek, variation in peak mean daily flow did not significantly impact juvenile density. Although macroinvertebrate prey were not limiting factors for juvenile coho in 2001, increased coho density was correlated with significant declines in the percentage of vulnerable macroinvertebrates at sampling locations. In addition, San Geronimo Creek had relatively high densities of juvenile coho, despite local evidence of excess nutrients and fecal coliforms from 2001. Analyzing fourteen years of qualitative sediment accumulation observations from Lagunitas tributaries, we found that 1) regular sediment inputs from tributaries could be impacting local habitat quality and may require source investigation, and 2) the highest sediment delivery occurred during wet years, but localized sediment accumulation may also occur in low flow years due to lag time in sediment delivery.

  • Upper San Geronimo Creek
    California Department of Fish and Game Lagunitas Watershed Stream Habitat Assessment Reports Upper San Geronimo Creek 1 Upper San Geronimo Creek 2007 STREAM INVENTORY REPORT Upper San Geronimo Creek Assessment completed 2007 Report Completed 2009 INTRODUCTION A stream inventory was conducted on 9/27/2007 on the upper reaches of San Geronimo Creek. The survey began at the confluence of San Geronimo Creek and Woodacre Creek (38°00’48.0” N 122°38’47.0” W) near the intersection of Railroad Avenue and San Geronimo Valley Drive in Woodacre, California and extended upstream 1.8 miles. The Upper San Geronimo Creek inventory was conducted in two parts: habitat inventory and biological inventory. The objective of the habitat inventory was to document the habitat available to anadromous salmonids in Upper San Geronimo Creek. The objective of the biological inventory was to document the presence and distribution of juvenile salmonid species. The objective of this report is to document the current habitat conditions and recommend options for the potential enhancement of habitat for Chinook salmon, coho salmon, and steelhead trout. Recommendations for habitat improvement activities are based upon target habitat values suitable for salmonids in California's north coast streams. WATERSHED OVERVIEW San Geronimo Creek is located in Marin County, California (Map 1), and is a tributary to Lagunitas Creek, which runs into Tomales Bay, before heading out to the Pacific Ocean. Upper San Geronimo Creek's legal description at the confluence with its unnamed tributary is T02N R07W S17. Its location is 38° 00’48.0” north latitude and 122° 38’47.0” west longitude, LLID number 1226462380132.

Extensive habitat surveys found fewer instances of juvenile salmonids in drying reaches than any previous year, likely due to the complete lack of spawning by adult coho in the San Geronimo Creek tributaries winter 2008/09. Fish were relocated from drying pools in Arroyo Creek, Larsen Creek, and North Fork of San Geronimo Creek. This was the eleventh year of SPAWN's salmonid rescue and relocation program, which began in 1999 under permits from the National Marine Fisheries Service (NMFS) and California Department of Fish and Game (DFG). To date, a total of 22,196 salmonids have been rescued and safely relocated by SPAWN. Introduction Coho salmon (Oncorhynchus kisutch) and steelhead trout (Oncorhynchus mykiss) are found in the Lagunitas Creek Watershed, Marin County. California Coast coho salmon are listed as endangered under the State and Federal Endangered Species Act, while steelhead trout in this region are listed as threatened (Central California Evolutionary Significant Unit).
