CHARG is comprised of agencies and organizations across the region which are responsible for implementing solutions to address coastal hazards.


Our History

CHARG was initiated in 2014 by the public agencies responsible for implementing strategies to reduce the impacts of sea level rise, king tides, and extreme weather on San Francisco Bay shoreline communities. With more than 120 stakeholders, CHARG hosted focused workshops and sub-group meetings around the Bay Area to tackle the sea level rise-related policy, funding, and technical challenges facing the region. Providing a platform for local jurisdictions, NGOs, State and Federal agencies, and the public, CHARG addresses the many challenges to sea level rise at a regional scale and recognizes that a “One Bay” approach with a unified voice is essential to protecting our regional asset.

Acknowledging the growth in sea level rise awareness and regional adaptation planning around San Francisco Bay since 2014, CHARG shifted its focus in 2017 to supporting technical studies and solutions to inform regional adaption, policy, and funding decisions. In 2018, CHARG became a Strategic Initiative of BAFPAA. CHARG seeks to engage all local flood control districts and stakeholders from San Francisco Bay through the Sacramento-San Joaquin Delta to advance the scientific foundation needed to direct sea level rise adaptation at a regional scale.

Our Future

CHARG envisions a future in which all residents of and visitors to the Bay area, and the important infrastructure, property, and other assets on which they depend, can thrive in the face of the coastal hazards facing our region. CHARG’s mission is to improve and protect quality of life for San Francisco Bay communities by providing the strong technical and engineering basis needed to support critical policy, funding, and implementation decision-making around regional sea level rise adaptation.

CHARG Leadership

Leadership is comprised of BAFPAA members representing flood protection agencies around the Bay.

CHARG Steering Committee

The Steering Committee includes representatives from regional, state and federal agencies; private business and Non-Governmental Organizations with a focus or interest in addressing sea level rise. They provide thought leadership, technical guidance, and offer strategy input for CHARG.

What We Think...


The “one project one benefit” is a thing of the past. The leaders of San Mateo County and its partner cities know that a multi-jurisdictional, multi-benefit approach is needed to enhance our watersheds to make them sustainable and resilient to the impacts of extreme weather events.

— Erika Powell
Flood and Resiliency Program Manager, San Mateo County

Working together to develop solutions to the problems we all face is logical and cost effective.

— Richard Thomasser
Watershed and Flood Control Operations Manager, Napa County Flood Control and Water Conservation District

The San Francisco Bay Area has all of the assets and capacity to be a national model for how an urban region at the edge of sea, adapts to climate change. Public, flood management officials must be at the forefront of that leadership.

— Warner Chabot
Executive Director, San Francisco Estuary Institute

San Mateo County recognizes that a “one shoreline” approach to creating resilient, 21st Century solutions is important to addressing sea level rise. Collaborating across jurisdictions is critical to protecting people, properties, and our ecosystems.

— Jim Porter
Director, San Mateo County Public Works

Climate change is the challenge of our
generation. It is worthy of our passion
and our future deserves it.

— Norma Camacho
CEO, Valley Water

Many of the industrial facilities along the Contra Costa County Shoreline are at great risk of disruption from rising seas. I’m happy to see the growing awareness of this issue, and the need for well thought out technical solutions. CHARG is the vehicle that can help provide that.

— Paul Detjens
Program Manager, Contra Costa County Flood Control District

As perhaps the most vulnerable of the nine Bay Area counties to sea level rise, Marin County has been a leader in pilot projects for natural (green) shoreline solutions such as tidal wetlands and bay beach designs. However, the predicted rise in sea level of several feet will likely require a mix of natural and more traditional engineering as well as innovative planning adaptation solutions. Education and outreach are also vitally important to adaptation planning. Marin County Flood Control will work within CHARG to design and implement solutions that meet these challenges.

Senior Engineer, Marin County Flood Control District
