In This Delaware Flood Insurance Guide:
Is Delaware Flood Insurance Required?
Standard homeowners insurance does NOT cover flood damage in Delaware or any other state. This is one of the most common and costly misconceptions among homeowners. If your home is damaged by flooding — whether from a hurricane, heavy rain, river overflow, or storm surge — your standard HO-3 policy will not pay for repairs.
If you have a federally backed mortgage (FHA, VA, USDA, or conventional through Fannie Mae/Freddie Mac) and your property is in a FEMA-designated Special Flood Hazard Area (SFHA), flood insurance is mandatory. Your lender will require you to maintain flood coverage as a condition of the loan.
Even if flood insurance is not required for your property, it is strongly recommended. FEMA data shows that approximately 25% of all flood claims come from properties outside high-risk flood zones. Just one inch of floodwater can cause over $25,000 in damage.
FEMA Flood Zones in Delaware
Delaware is a low-lying coastal state with significant SFHA exposure, particularly along the Atlantic coast and Delaware Bay shoreline. FEMA designates Zone AE (high-risk riverine and coastal) and Zone VE (coastal with wave action) areas throughout Sussex and Kent counties. Flood Insurance Rate Maps are actively maintained by DNREC and Sussex County, with ongoing updates under Risk Rating 2.0.
Areas in Delaware with the highest flood risk include:
- Lewes
- Rehoboth Beach
- Bethany Beach
- Fenwick Island
- Delaware City
- Dewey Beach
- Slaughter Beach
- Milford
Notable flood events in Delaware’s history include:
- Ash Wednesday Nor’easter 1962
- Hurricane Floyd 1999
- Tropical Storm Henri 2003
- Hurricane Irene 2011
- Superstorm Sandy 2012
These events underscore why Delaware flood insurance is essential protection.
NFIP Flood Insurance Coverage & Costs in Delaware
The National Flood Insurance Program (NFIP), administered by FEMA, is the primary source of flood insurance in Delaware. NFIP policies are sold through private insurance agents but are backed by the federal government.
The average annual NFIP premium in Delaware is approximately $724. This is below national average NFIP premium of approximately 926 the national average NFIP premium of approximately $900 per year.
Active NFIP policies: Delaware has approximately 26786 active NFIP policies.
NFIP residential coverage limits:
| Building Coverage (max) | $250,000 |
| Contents Coverage (max) | $100,000 |
| Deductible Options | $1,000 – $10,000 |
| Waiting Period | 30 days for new NFIP policies, 0 if at closing |
| Basement Coverage | Limited — structural elements only |
Important NFIP limitations: NFIP policies do not cover finished basements, landscaping, currency, precious metals, or temporary housing costs. Maximum residential building coverage is $250,000 — homeowners with properties valued above this should consider a private flood policy or excess flood coverage.
Private Flood Insurance in Delaware
In addition to the NFIP, private flood insurance is available in Delaware from companies including:
- Neptune Flood
- Wright Flood
- Palomar Insurance
- Hiscox FloodPlus
- Zurich Flood
Private flood policies may offer higher coverage limits (above the $250,000 NFIP cap), shorter waiting periods, replacement cost coverage, and additional living expense (ALE) coverage that NFIP does not provide.
State-specific flood programs: DNREC Floodplain Management Program serves as state coordinating agency for NFIP; multiple communities participate in FEMA Community Rating System (CRS) earning 5-10 percent premium discounts; Delaware Flood Planning Tool provides interactive flood risk mapping; Delaware Coastal Flood Monitoring System provides 48-hour advance flood alerts along Delaware Bay coastline

How to Save on Delaware Flood Insurance
Flood insurance costs vary significantly based on your property’s flood zone, elevation, and coverage options. Here are proven strategies to reduce your premium:
- Elevation Certificate: Documents your home’s elevation relative to the Base Flood Elevation. If above BFE, you may qualify for significantly lower NFIP rates.
- Compare NFIP vs private flood: Private flood insurers may offer lower rates for properties in certain risk zones.
- Higher deductible: Increasing your deductible from $1,000 to $5,000 or $10,000 can reduce your premium substantially.
- Flood mitigation improvements: Flood vents, elevated utilities, and sump pumps can qualify you for lower rates.
- Preferred Risk Policy: Properties in moderate-to-low risk zones (Zone B, C, or X) may qualify for rates as low as $300-$500/year.
- Community Rating System (CRS): Communities in FEMA’s CRS program give all policyholders a 5-45% discount.
