9.1 National Flood Insurance Program (NFIP), NYPIUA & Wind-Versus-Water Losses

Why Flood Is a Separate Policy

Homeowners, dwelling, businessowners, and commercial property forms all exclude flood, surface water, waves, tidal water, and storm surge under a water exclusion with an anti-concurrent-causation lead-in. For most New York property owners, the answer is the National Flood Insurance Program (NFIP). The NFIP was created by the National Flood Insurance Act of 1968 and is administered by the Federal Emergency Management Agency (FEMA).

Program Structure and Eligibility

The Definition of Flood

Under the Standard Flood Insurance Policy (SFIP), a flood is a general and temporary condition of partial or complete inundation of two or more acres of normally dry land area or of two or more properties (at least one of which is the policyholder's property) from:

1. Overflow of inland or tidal waters;
2. Unusual and rapid accumulation or runoff of surface waters from any source;
3. Mudflow; or
4. Collapse or subsidence of land along the shore of a lake or similar body of water caused by erosion or undermining from waves or currents exceeding anticipated cyclical levels that result in a flood as defined above.

A clogged gutter that floods one basement, with no inundation of two acres or two properties, is not a flood under the SFIP. The homeowners policy may still exclude the loss as surface water. The PA must then look at every possible coverage grant, such as a water back-up endorsement if the water came through a drain.

Coverage Limits

Increased Cost of Compliance (ICC) pays up to $30,000 when a building is declared substantially or repetitively damaged and must be elevated, floodproofed, relocated, or demolished to meet floodplain rules. ICC is added to the building coverage, but building plus ICC cannot exceed the statutory maximum for that building type. Separate deductibles apply to building and contents.

The Three SFIP Forms

• Dwelling Form: one- to four-family residences and individual residential condominium units.
• General Property Form: other residential buildings (five or more units) and non-residential buildings.
• Residential Condominium Building Association Policy (RCBAP): the condominium association's building.

Valuation and Key Restrictions

• Replacement cost applies under the Dwelling Form only to a single-family dwelling that is the insured's principal residence, insured to at least 80% of replacement cost or to the maximum amount available. Otherwise the building is settled at actual cash value.
• Contents are settled at actual cash value.
• Basements and enclosures below the lowest elevated floor: coverage is limited to listed items, such as foundation elements, central air and heating equipment, water heaters, electrical panels, fuel tanks, pumps, unfinished drywall, clothes washers and dryers, and food freezers. Finished walls, floor coverings, furniture, and most other contents in a basement are not covered.
• No additional living expense or loss-of-use coverage, and no business interruption.
• Loss avoidance: the SFIP pays limited amounts for sandbags and similar supplies, and for property moved to protect it from a flood, subject to its terms.

Claim Procedure

• The policyholder must send a signed and sworn proof of loss within 60 days after the loss. FEMA may extend the deadline by bulletin after major events; for example, it extended the deadline for Hurricane Helene claims. The 60-day rule is a condition of the federal policy. It does not follow New York's § 3407 trigger for state-regulated policies.
• If a claim is denied in whole or in part, the policyholder may appeal to FEMA, and any lawsuit must be filed within one year after the date of the written denial in the United States District Court for the district where the property is located.

New York's Residual Market: NYPIUA and C-MAP

The New York Property Insurance Underwriting Association (NYPIUA), created in 1968, is the state's FAIR Plan. It is an association of insurers that provides basic property (dwelling fire) insurance to owners who cannot obtain coverage in the voluntary market. The Coastal Market Assistance Program (C-MAP) was established by the State Insurance Department and is administered by NYPIUA to help homeowners in coastal areas obtain coverage from participating voluntary insurers. Neither replaces flood insurance. NYPIUA and C-MAP policies exclude flood like other property forms.

Wind vs. Water: Segregating a Coastal Loss

After a coastal storm, the property insurer excludes the flood and storm-surge damage, and the NFIP pays only for flood. The PA's job is to separate the damage so each policy pays its share:

1. Establish the high-water mark inside and outside the building. Damage above it (roof, upper walls, ceilings) points to wind or wind-driven rain through a storm-created opening.
2. Build a timeline from weather and tide-gauge data showing when winds peaked and when surge arrived.
3. Document the building envelope: missing shingles, broken windows, and debris impacts support the wind claim.
4. Use engineers when structural failure could be wind pressure or wave action.
5. Submit separate, consistent claims: an SFIP proof of loss for flood damage and a property claim for wind damage. The documents must not contradict each other.

Because the anti-concurrent-causation lead-in bars damage to which flood contributed, the strongest wind claims show damage that occurred before or independently of the water.
