Only partly. An NFIP flood policy covers direct physical flood damage, but it excludes earth movement — including settlement and subsidence — even when a flood directly caused it. So uneven settling after a flood is usually not covered. If your insured home is substantially damaged, Increased Cost of Compliance can pay up to $30,000 toward elevation.
Foundation Repair Baton Rouge hears this question most from homeowners in Central, Denham Springs, Walker and Gonzales who flooded in 2016. Here’s how the policy language works in practice.
What the flood policy excludes
The Standard Flood Insurance Policy excludes earth movement, and FEMA’s own appeal decisions make the point bluntly: the policy excludes earth movement even if directly caused by flood. Earth movement includes land subsidence, sinkholes, destabilization of land from water accumulation, and gradual erosion. In one published decision, FEMA rejected a foundation claim even though the engineer tied the damage to settlement, because settlement is not a covered cause of loss.
That’s the main reason post-flood foundation problems in Baton Rouge are usually paid out of pocket: the typical failure is saturated fill and clay consolidating unevenly after the water recedes, which is earth movement.
Which policy pays? Common post-flood foundation situations
This table is our plain-language summary of the sources listed at the bottom of the page. It is not a coverage decision; only your policy and adjuster can make that.
| Situation | Flood policy (NFIP) | Homeowners policy |
|---|---|---|
| Floodwater scours or breaks foundation elements | May cover as direct flood damage | Excluded (flood) |
| Slab or piers settle unevenly months after the water recedes | Usually excluded (earth movement) | Usually excluded (earth movement) |
| Crawl space and foundation cleanup after the flood | Typically covered as flood damage | Excluded (flood) |
| Home is substantially damaged and must be elevated | ICC may pay up to $30,000 toward elevation, if you hold a policy | Not covered |
| Under-slab plumbing line broke (not flood) | Not a flood loss | May be covered; see homeowners coverage |
What it may cover
- Direct physical damage to foundation elements from floodwater — for example, damage from fast-moving water or scour.
- Cleanup of the foundation and crawl space.
- Increased Cost of Compliance (ICC) — up to $30,000 toward elevation, floodproofing, demolition or relocation when a building is substantially damaged or meets repetitive-loss criteria. It’s paid in addition to the building claim.
How ICC eligibility works
FEMA’s ICC page (updated Jan. 12, 2026) sets two triggers. Substantial damage means your community determines repairs will cost 50% or more of the building’s pre-damage market value. Repetitive damage means the building flooded twice in 10 years, each time with repair costs averaging 25% or more of market value, and both floods produced flood insurance payments. The determination is made when you apply for a building permit, and you must hold a flood policy. ICC is adjusted separately from the damage claim. After your insurer has a signed contract, a community permit and your signed Proof of Loss, FEMA says you can receive an advance of up to half the benefit or $15,000; the final payment follows the local inspection. Because ICC pays only for elevation, demolition, relocation or floodproofing, it will not fund a pier or piling repair.
Other funding for flooded homes
FEMA Flood Mitigation Assistance grants, applied for through your parish, typically cover 75% of eligible elevation costs and up to 90–100% for repetitive-loss properties. Your parish floodplain manager is the right first call. See house raising cost in Louisiana for the full picture.
What to do after a flood
Update, Nov. 2, 2026: FEMA announced on Oct. 20, 2026 that flood policies can now be bought online; see FEMA now sells flood insurance online if you are shopping for a policy before the next season. The Louisiana Department of Insurance’s consumer guide notes it may take 30 days after purchase for flood coverage to take effect, so buy before you need it.
Document damage before cleanup, file the flood claim promptly, and ask about ICC if the home may be substantially damaged. Then watch the house over the following months and years — new drywall cracks and doors that begin to bind are signs of post-flood settlement. See foundation damage after a flood.

Bottom line
Flood insurance pays for direct flood damage but not for settlement, even flood-caused settlement. ICC and mitigation grants are the main help for elevating. For an honest look at repair-in-place versus raising, call Foundation Repair Baton Rouge.
