Michael Frost, 1st Vice President

Michael Frost was born in Redding and grew up fishing the Sacramento River and Pacific Ocean. He settled in the Bay Area after graduating from the University of Oregon in 1998. Michael works in sales in the Silicon Valley and lives with his wife and daughter in San Carlos. Michael is an advocate for the taxpayers of California and promotes the use of 21st century technology, such as data analytics and the smart grid, to help solve some of today’s most pressing problems.

As a member of the engaged philanthropy group, Full Circle Fund, Michael donates his time and money to non-profit organizations benefiting education, the environment, and global economic opportunity.

Fishing has been a lifelong passion for Michael. The California Delta and San Francisco Bay have provided the perfect playground in the Bay Area’s backyard. He has become involved with Restore the Delta after witnessing the rapid decline of the west coast salmon fishery during his short lifetime. The economic value of the Delta’s environment is something that Michael would like to highlight and promote to all Calfornians. This renewable resource is a gift that will keep on giving with proper care.

E. Robert Wright, Board Member

bobwright
Bob is an AV Martindale-Hubbell rated lawyer and Counsel for Sierra Club California. His legal career in Fresno and Sacramento started in 1972 and has ranged from being a law firm partner in private practice including representation of groups seeking enforcement of environmental laws to public practice prosecuting environmental and white collar crime. He was Adjunct Professor of Environmental Law at San Joaquin College of Law in Fresno from 1990 to 2003.

When Friends of the River challenged the Army Corps of Engineers’ rule prohibiting any vegetation other than grass on all of the nation’s levees and the Corps moved to dismiss, Bob won the decision denying that motion. Other victories include the decision in the national class action that school buildings are damaged by the mere presence of asbestos; and the decision finding that the nationwide U.S. Forest Service anti-wilderness land management planning known as RARE II (roadless area review and evaluation) violated the National Environmental Policy Act. Bob also led the inter-disciplinary planning team that developed the Regional Plan adopted by the California Tahoe Regional Planning Agency in 1975.

Bob obtained a B.S. in Business Administration from the University of California, Berkeley in 1966, and after serving as a Captain in the U.S. Army, obtained a J.D. from Harvard Law School in 1971. He has been a member of the California Bar since 1972.

“After all these years in water policy, one resounding lesson is clear: the more I learn about water, the more I know I don’t know. I’ve lived in the Delta region for most of my life and I deeply care about its future.”

She has defended the pillars of the Clean Water Act, a fishable, swimmable, drinkable, and farmable San Francisco Bay-Delta Estuary. She has led a coalition that envisions the Sacramento-San Joaquin Delta as a place where a vibrant local economy, tourism, recreation, farming, wildlife, and fisheries thrive as a result of inclusive resident efforts to protect our waterway commons.
