Closing the Resilience Gap: What Will it Take?

Based on PBS’s Sinking Cities: Miami

The Science and Realities in the Tampa Bay Area

• Dr. Davina L. Passeri

Research Oceanographer U.S. Geological Survey

• St. Petersburg Coastal and Marine Science Center

Coastal response to sea level rise

• The coast is not a bathtub!
• We need to consider how the coast will respond to higher water levels
• Increased tidal flooding, storm surge flooding, beach erosion, wetland loss

Restoration strategies for coastal resilience

• Hard structures
• Sea walls
• Jetties
• Breakwaters
• Natural and Nature-Based

Features

• Dune restoration
• Beach nourishment
• Marshes, seagrass beds,
• yster reefs
• Outcomes
• Wave attenuation
• Shoreline stabilization
• Storm surge reduction

• Resiliency Planning is a Public Good
• The efficient allocation will not be met by the private market due to free-rider problem
• How do you size a Resilience Strategy?
• Cost-Benefit Analysis
• Stormwater Master Plan Update and the Miami Forever Bond
• Master Plan is in progress
• $192M dedicated to sea level rise mitigation and flood prevention
• Who Pays?
• We can quantify the consequences of an inadequately funded stormwater system
• Protection of Property Values and the Macroeconomy

• 2 feet rise by 2060, downtown and beach below sea level
• 6 feet rise by 2100!
• Vulnerable displacement as a result
• Class differences in how people respond
• Climate Gentrification
• Resilience no matter what the cost?
• “Retreat is not an option”
• Is spending so much money here the optimal option?
• Ethical Theory: Utilitarianism vs Natural Rights
• Most good/happiness vs. Our rights and obligations to each other
