San Francisco Estuary Institute, Oakland, Ca. ii ACKNOWLEDGMENTS The authors would like to thank the RMP Sources Pathways and Loadings Workgroup for developing the concepts the lead to the review of literature and available data pertaining to runoff of water, sediment and contaminants in the Bay Area urban and rural landscape. Active workgroup members have included: Andy Gunther, Andy Jahn, Dave Tucker, Don Yee, Dyan Whyte, Fred Hetzel, Jon Konnan, Jim Kuwabara, Jim McGrath, Khalil Abu-Saba, Neil Ganju, Richard Looker, Russ Flegal, Terry Cooke, Tom Hall, Tomas Mumley, and Trish Mulvey. We would specifically like to thank the following reviewers: Jan Null of Golden Gate Weather Services, Ray Wilson, Scott Wright, Joe Domagalski, and Jeff Steuer of the United States Geological Survey, Andy Jahn of the Port of Oakland, Andy Gunther of Applied Marine Sciences, Trish Mulvey of Clean South Bay, and Fred Hetzel and Mike Napolitano of the San Francisco Bay Regional Water Quality Control Board. The comments, both broad and general improved the quality of data and interpretations and readability of each chapter and helped to make the overall product more useful to a wide audience. We would like to thank Eric Wittner of SFEI for assistance with development of GIS maps and figures displaying spatial data within the document. We greatly acknowledge the assistance of Patricia Chambers and her colleagues at SFEI for final layout, production and web publishing iii TABLE OF CONTENTS Part 1:

It is defined by the Office of Management and Budget to include core areas more directly economically influenced by San Francisco rather than outlying cities such as San Jose which has its own MSA, the San Jose–Sunnyvale–Santa Clara, CA MSA. Until 2013, this MSA was known as the San Francisco–Oakland–Fremont, CA MSA.[1][2] The Federal Government definition states that it consists of 5 counties, grouped into three divisions.[2] Those 5 counties are San Francisco, Alameda, Marin, Contra Costa, and San Mateo County.[2] The three divisions are Oakland–Hayward–Berkeley (Alameda and Contra Costa Counties), San Francisco–Redwood City–South San Francisco (San Francisco and San Mateo Counties), and San The component Metropolitan Statistical Rafael (Marin County).[2] Areas and their geographical location within the San Jose–San Francisco– The MSA is a subset of the 9 county San Francisco Bay Area, as Oakland, CSA.

The term "this office" refers to the appropriate District or Division office of the Corps of Engineers (Corps) having jurisdiction over the permitted activity or the appropriate official of that office acting under the authority of the commanding officer. You are authorized to perform work in accordance with the terms and conditions specified below: PROJECT DESCRIPTION: The Santa Clara Valley Water District (“Valley Water”) will conduct Stream Maintenance Program Phase 2 (SMP2) activities in streams and channels throughout Santa Clara County for the primary purpose of reducing flood risk. Additional program goals include maintaining the structural and functional integrity of Valley Water facilities while protecting public safety, water quality, and aquatic habitat values. SMP2 maintenance activities include bank stabilization, sediment removal, vegetation management, management of animal conflicts, and minor maintenance activities, as described in the 2019-2023 Stream Maintenance Program Manual (“SMP2 Manual,” March 5, 2020). Bank stabilization projects will repair eroded stream beds and banks to protect existing infrastructure, reduce sediment loading, and preserve water quality and habitat values. Sediment removal projects will remove excess sediment from stream channels to maintain flow conveyance, reduce flood risk, or improve fish passage.

A Technical Report of the Regional Watershed Program: SFEI Contribution 409. San Francisco Estuary Institute, Oakland, CA. 72pp. ii McKee, Leatherbarrow, and Oram, 2005 EXECUTIVE SUMMARY This report summarizes and interprets mercury, trace elements, PCBs and OC pesticides concentration data collected in Guadalupe River water during the winter seasons of water years 2003 and 2004. Our objective is to describe concentration variability between years and to determine loads. We will present some hypotheses on the processes of mercury source, release, and transport and the source, release, and transport processes of other trace elements and the organic contaminants. We estimate total mercury loads, loads of other total trace elements, loads of PCBs and OC pesticides entering San Francisco Bay under the range of climatic conditions encountered. In addition, we use a simple rating curve method to estimate a five-year average mercury loads and a probable maximum mercury load based upon observed rainfall intensity and runoff data from water year 1975 – 2004.

  • Friends of Five Creeks Letters Re Restoration of Codornices Creek
    The letters below deal with F5C’s early involvement in Codornices Creek. They shed some light on challenges that faced efforts to restore our area’s only trout stream, and the role citizens played. These are by no means the whole story. Most credit for the big projects on Codornices west of San Pablo goes to the partnership of creek-restoration pioneers Carole Schemmerling, who headed the now defunct Urban Creeks Council, and consulting hydrologist Dr. Ann Riley, whose now defunct private consulting firm Watershed Restoration Institute. The two shared offices; UCC was effectively the nonprofit arm of WRI, able to receive grants and similar government support. Credit also goes to longtime environmental visionary Richard Register, who with UCC played a large role in bringing Codornices out of its pipe between 8th and 9th Streets in 1994-5. This was one of Berkeley’s pioneer “daylighting” projects. Friends of Five Creeks 1000 San Pablo Ave. Albany, CA 94706 412 7257 October 4, 1998 Mr. Ron Gervason San Francisco Bay Regional Water Quality Control Board 1515 Clay St., 14th Floor Oakland, CA 94612 [email protected] Re: Triannual Review of Water Quality Control Plan of San Francisco Bay Basin Friends of Five Creeks is a grassroots organization that seeks to protect and restore creeks in Albany, California. While Albany’s natural creeks are mostly in culverts, one, Codornices, is substantially free flowing and has a small trout population. Efforts are ongoing to restore another, Cerrito Creek. We believe that the few creeks in our urbanized area that can or do support relatively natural aquatic life, especially cold-water or anadromous fish, should receive the highest possible degree of protection, including that of the Regional Water Quality Control Board.

    Mákkin Mak Muwékma Wolwóolum, ’Akkoyt Mak-Warep, Manne Mak Hiswi! We Are Muwekma Ohlone, Welcome To Our Ancestral Homeland! Muwekma Ohlone Tribal Land Acknowledgment For The City of San Jose and Surrounding Region Thámien Ancestral Muwekma Ohlone Territory We would like to recognize that while we gather at the Indian Health Center of Santa Clara Valley located in the City of San Jose, we are gathered on the ethno-historic tribal territory of the Thámien Ohlone- speaking tribal groups, which included the lands of the Paleños - whose tribal region was named after their powerful chief Capitan Pala, and the two Mexican land grants located in the East Hills above San Jose - and who were intermarried with the direct ancestors of some of the lineages enrolled in the Muwekma Ohlone Tribe of the San Francisco Bay Area, whom were missionized into Missions Santa Clara, San Jose, and San Francisco. The present-day Muwekma Ohlone Tribe, with an enrolled Bureau of Indian Affairs documented membership of over 600 members, is comprised of all of the known surviving Indian lineages aboriginal to the San Francisco Bay region who trace the Tribe’s ancestry through the Missions Santa Clara, San Jose, and San Francisco, during the advent of the Hispano-European empire into Alta California beginning in AD 1769. The Muwekma families are the successors and living members of the sovereign, historic, previously Federally Recognized Verona Band of Alameda County, now formally recognized as the Muwekma Ohlone Tribe of San Francisco Bay Area. Muwekma means La Gente – The People in our traditional Chochenyo-Ohlone language.
