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

CHARG – Coastal Hazards Adaptation Resiliency Group

Regional Solutions Require Regional Participation
