Quick answer: Flood Mitigation Assistance (FMA) is FEMA’s annual grant program built specifically to reduce flood damage to NFIP-insured properties — and home elevation is one of its flagship uses. Standard projects are funded at up to 75% federal share, but the program is deliberately tilted toward the homes that flood over and over: repetitive loss properties qualify for up to 90%, and severe repetitive loss properties up to 100% federal funding. In South Carolina the program runs through the state’s flood mitigation program at SCDNR, with communities applying on behalf of homeowners each cycle.
What Makes FMA Different
FEMA runs two big mitigation grant engines, and confusing them costs homeowners real opportunities:
- HMGP exists only after a Presidential disaster declaration — episodic, administered by SCEMD.
- FMA exists every year — a standing national competition, funded by the NFIP itself, aimed exclusively at flood risk, and administered in South Carolina through the state flood mitigation program under SCDNR, the state’s NFIP coordinating agency.
That yearly cadence changes the strategy. You don’t wait for a hurricane to create a window — you position your property for the next cycle: NFIP policy in force, loss history documented, an elevation assessment quantifying the project, and your floodplain administrator aware you want in.
The NFIP-insurance requirement is absolute and worth repeating, because it’s where candidates die quietly: FMA only funds properties insured under the NFIP at application. Letting a policy lapse after a bad claim year — exactly when frustrated homeowners are tempted — forfeits eligibility for the program most likely to fund their way out.
The Cost-Share Ladder: Why Flooding History Is Worth Money
FMA’s federal share scales with how badly the NFIP wants to stop paying claims on your house:
| Property status | Federal share |
|---|---|
| Standard NFIP-insured property | up to 75% |
| Repetitive loss (RL) | up to 90% |
| Severe repetitive loss (SRL) | up to 100% |
The designations are formal NFIP categories based on the number and size of past flood claims relative to the building’s value — your insurance agent or floodplain administrator can tell you whether your property carries either label. In Charleston, whole pockets do: the Church Creek basin in West Ashley is among the region’s densest repetitive-loss clusters, and the downtown-adjacent AE zones along the tidal creeks carry long claim histories.
For an SRL home, read that table literally: a fully federally funded elevation is on the menu. For RL homes, the remaining 10% is small enough that an ICC assignment or the SC Office of Resilience’s designated match funds — SCOR has committed disaster-recovery dollars specifically to matching FMA and HMGP projects, including structural home elevation — typically closes it.
FEMA has also run Swift Current, a newer FMA pathway that pushes elevation funding to NFIP-insured, substantially damaged homes on an accelerated post-disaster timeline rather than the annual cycle. Availability depends on FEMA allocations, but it’s worth asking about by name if your home holds a fresh substantial damage determination.
How the Application Actually Moves
Like HMGP, FMA is a community application — homeowners are included, not applicants:
- FEMA publishes the annual FMA funding notice.
- South Carolina’s flood mitigation program (SCDNR) coordinates the state’s submissions.
- Your municipality or county assembles property-level projects — elevations, acquisitions, drainage work — from homeowners who’ve expressed interest and documented their case.
- FEMA scores the national competition; awarded projects flow back through the state to the community, which contracts the work.
The homeowner’s job is the same as with HMGP, just on a calendar instead of a catastrophe: be findable and be documented. Loss history assembled, NFIP policy current, elevation cost quantified, floodplain administrator on a first-name basis. Communities build applications from the homeowners they know about.
Reading Your Own Odds
Rank yourself honestly against what FMA rewards: NFIP policy in force (required), mapped flood zone (near-required in practice), claim history (each claim strengthens the benefit-cost math), RL/SRL designation (moves you up the cost-share ladder), and a shovel-ready project number. A West Ashley home with three claims and an SRL letter is a genuinely elite FMA candidate; a never-flooded home with no policy isn’t in the game.
If you don’t know where you stand, that’s the first fixable problem: request a free assessment and we’ll establish your zone, target elevation, and project cost — the numbers every FMA application is built on — and point you to the right floodplain office to get on the list for the next cycle.
