Coastal real estate faces escalating risks from climate change, particularly due to sea-level rise, intensified storms, and chronic flooding. While property values in vulnerable areas continue to rise due to federal subsidies and tax incentives, long-term viability depends on robust risk assessment and proactive mitigation strategies. Below, we analyze the challenges and solutions shaping this sector.
Risk Assessment
Physical and Financial Exposure
By 2050, up to $106 billion worth of U.S. coastal property could be submerged, with 300,000 homes at risk of regular flooding by 2045. Advanced climate risk assessment tools now enable investors to evaluate properties against multiple risks-including coastal floods and tropical cyclones-across a range of climate scenarios. These assessments are critical for pricing risks accurately and avoiding overexposure.
Market Distortions
Federal subsidies for storm damage mitigation and tax breaks for high-income buyers artificially inflate coastal property values, delaying market adjustments to climate realities. This creates a “coastal gentrification” cycle, where only wealthier individuals can afford localized defenses like seawalls.
Mitigation Strategies
Engineering Solutions
-
Elevated Structures and Seawalls: Commonly used to combat flooding, though their long-term effectiveness is debated.
-
Modular Housing: Public investments in movable, climate-resilient homes could reduce reliance on fixed infrastructure.
Policy Interventions
-
Managed Retreat: Phased relocation programs, where residents lease properties temporarily, allow communities to retreat sustainably without financial ruin.
-
Wetland Restoration: Natural barriers like marshes and coral reefs can absorb a significant portion of wave energy, offering cost-effective protection.
Market Adjustments
Reducing subsidies and integrating climate risk into insurance models could align property prices with actual hazards. Coastal zoning laws that restrict high-risk development are also gaining traction.
