CHARG Strategic Brief
CHARG – Coastal Hazards Adaptation Resiliency Group
Trend of historic data and Sea Level Rise (SLR) projections
CHARG – Coastal Hazards Adaptation Resiliency Group
Impacts of Sea Level Rise will be Serious for the Bay
Negative impacts by SLR will be felt locally, regionally, statewide, nationally and internationally
Threaten people’s lives and their safety Can seriously disrupt commerce,
resulting in lost wages and lower productivity
Degrade water quality and drinking water supply
Impact our infrastructure and value of properties in the trillions
Can result on loss of critical tidal habitat
CHARG – Coastal Hazards Adaptation Resiliency Group
Why CHARG and Why Now? Variability of the SLR projections require adaptation of a Bay-
wide uniform approach What if we build a wall for it ? How deep and tall should it be
and where to connect it? FEMA latest extreme tide study and its side effects Projects already funded and ready to proceed forward What about SLR effects on our groundwater and aquifers? What about effects of SLR on our ecosystem and how to
minimize impacts of our proposed mitigations? Can we afford the future of the Bay to be configured based
on individual reactions of coastal land owners or communities to SLR?
CHARG – Coastal Hazards Adaptation Resiliency Group
The Waters of the San Francisco Bay Know No Boundaries
Managing the impacts of rising waters will require unprecedented collective efforts
Never before has there been a more unifying need to join forces to protect the safety and welfare of the region’s people, property and rich ecology
CHARG – Coastal Hazards Adaptation Resiliency Group
SLR mitigation requires multi-jurisdictional and multi-level collaboration to address its complexity
Solutions to reduce the hazards’ risks must satisfy multiple goals to name a few:
• Coastal flooding• Housing and industry• Infrastructure (transportation, wastewater, water supply)• Recreation + open space• Habitat
Need to accept or reject ideas and alternatives systematically and methodically
We must work together
CHARG – Coastal Hazards Adaptation Resiliency Group
How to unify our efforts and work together
Collaborate across all levels of government and align resources to implement integrated and multi-benefit coastal hazards solutions
CHARG – Coastal Hazards Adaptation Resiliency Group
CHARG Vision
Collaborate across all levels of government and align resources to implement integrated and multi-benefit coastal hazards solutions to mitigate risk and improve and protect quality of life and property along the San Francisco Bay.
CHARG – Coastal Hazards Adaptation Resiliency Group
The Implementers
100+ planners, scientists, engineers, and policy makers from local, state, and federal agencies and NGOs – all sharing responsibility to protect people and property from flooding and to enhance the Bay Area’s shoreline ecosystem
CHARG – Coastal Hazards Adaptation Resiliency Group
The Implementers: Steering Committee Alameda County Flood Control & Water Conservation District
Bay Area Joint Policy Committee
California Department of Water Resources
California State Coastal Conservancy
Contra Costa County Flood Control & Water Conservation
Federal Emergency Management Agency
Marin County Flood Control & Water Conservation District
San Francisco Bay Conservation and Development Commission
San Francisquito County Joint Powers Authority
Santa Clara Valley Water District
US Army Corp of Engineers, San Francisco District
CHARG – Coastal Hazards Adaptation Resiliency Group
REGION-wide GoalsReconnaissance: Understand current shoreline conditions, review various
studies and document projects around the Bay
Education: Educate ourselves + stakeholders about coastal hazard risks, vulnerabilities and alternatives for mitigation
Guidelines: Develop regionally agreed-upon guidelines to support regional strategies and unified approach
Implementation: Implement comprehensive strategies to mitigate risk
Operations: Support cross-jurisdictional and multi-level collaboration to effectively allocate resources and implement solutions
Networking: Partner to address critical issues for San Francisco Bay area also at the national and international levels to learn from others
CHARG – Coastal Hazards Adaptation Resiliency Group
CHARG Immediate Objectives
1: Improve regional coordination to address coastal hazards adaptation (Standards + BMPs Working Group)
2: Identify and work together to solve regional coastal hazards and flood management issues
3: Exchange ideas and expertise, and transfer technical knowledge
4: Provide a unified voice in support of regional policies (Policy Working Group)
5: Develop financing and funding strategies (Funding Working Group)
6: Move public education forward
