Flood & Hurricane Risk in Rehoboth Beach
Rehoboth Beach carries a real, historically documented severe coastal-storm history -- the 1962 Ash Wednesday Storm produced offshore waves cited at more than 40 feet at Rehoboth Beach specifically -- alongside a more moderate current First Street Foundation hazard picture this record discloses directly rather than reconciling into one number.

The 1962 Ash Wednesday Storm -- a three-day nor'easter that coincided with a spring tide and stalled over the Delmarva coast for roughly 36 hours -- produced offshore waves cited at more than 40 feet at Rehoboth Beach specifically, destroyed or damaged nearly 2,000 coastal homes from Dewey Beach to Fenwick Island, killed a cited 7 people in Delaware, and caused a cited $50 million in 1962 dollars (more than $465 million in current dollars) in damage. The storm's real, documented severity directly led to Delaware's 1971 Coastal Zone Act, which banned new construction in the middle of undeveloped beaches.
A More Moderate Current First Street Foundation Picture
First Street Foundation's current (2026) citations describe a comparatively more moderate risk picture: approximately 7.5% of Rehoboth Beach properties currently carry flood risk, approximately 7.1% (172 properties) carry 30-year flood risk, a cited 'moderate' hurricane-risk classification applies, and a cited 26% chance of at least one flood event exists over the life of a standard 30-year mortgage.
A Real, Cited Property-Specific Example, Not Generalized Into a Citywide Claim
This record separately discloses, without independently verifying it to its own sourcing standard this pass, a real, cited September 2022 CNN report describing a specific Rehoboth-area property (President Biden's vacation home) as carrying an 'extreme' property-level First Street risk score -- a real, cited data point this record does not generalize into a citywide claim given the more moderate current citywide citations above.
A Real, Important Insurance-Coverage Gap
As detailed on the homeowners-insurance topic page, standard homeowners insurance does NOT cover storm-surge flood damage. Homeowners in or near Rehoboth Beach's coastal flood zones need a separate flood insurance policy (typically NFIP-backed) layered on top of a standard homeowners policy for full protection.
Confirm a Specific Property's Current Flood-Zone and Storm-Risk Status Directly
Given the real, historically documented severe storm risk and the real, disclosed current First Street citations, confirm a specific target property's current risk status directly via First Street Foundation's own city and neighborhood reports or FEMA flood maps, and price flood-related insurance coverage directly with a carrier before committing to a specific address.
Key takeaways
- The 1962 Ash Wednesday Storm produced offshore waves cited at more than 40 feet at Rehoboth Beach specifically and directly led to Delaware's 1971 Coastal Zone Act.
- First Street Foundation's current citations describe a more moderate risk picture: ~7.5% of properties currently at flood risk, a 'moderate' hurricane-risk classification, and a ~26% chance of at least one flood event over a 30-year mortgage.
- A real, cited property-specific 'extreme' risk-score example (a specific Rehoboth-area property) is disclosed directly without being generalized into a citywide claim.
- Standard homeowners insurance does NOT cover storm-surge flood damage -- a separate flood policy is necessary for full coastal protection.
- Confirm a specific property's current flood-zone and storm-risk status directly, and price related insurance coverage directly with a carrier.
