Recovery funding, how fast it came

For each disaster, the wait from the declaration to the first federal obligation (amber), then the federal share obligating after that (teal), on a shared 7-year scale. Typical wait to the first obligation here: about 157 days. An obligation is the federal share committed to the recipient state, not funds disbursed to the locality, which comes later and is not shown.

Assistance to households (Individual Assistance)

FEMA Individual Assistance to households in this jurisdiction, combined across the Housing Assistance owner and renter programs. Valid registrations are households that applied within a designated Individual Assistance area; approved counts and dollars are the households FEMA found eligible under the Individuals and Households Program. Figures are self-reported and drawn from NEMIS through OpenFEMA, not audited, and Individual Assistance exists only for disasters where it was designated, so many jurisdictions show none.

State declarations (governor)

Emergency declarations issued by the governor of this state, which are separate from and usually precede a federal declaration. A declaration is listed here when NOAA Storm Events recorded reports of the matched hazard in this jurisdiction while the order was in effect. That is evidence of local impact during a declared state emergency. It is not a statement that the governor named this jurisdiction in the order, since most state declarations apply statewide and name no localities at all. Hazard categories come from the order text. Damage figures are NOAA storm report estimates for this jurisdiction only, not the cost of the declaration.

How these numbers are built

Drawn from FEMA's OpenFEMA Disaster Declarations Summaries, rebuilt each week. A declaration is counted here once for each designated area it names, so a single disaster covering many localities is counted in each one. For that reason these jurisdiction counts do not sum to South Carolina's statewide total. This page counts declarations that named this jurisdiction as a designated area. Totals cover complete fiscal years (Oct 1 to Sep 30); the in-progress year may appear in the most-recent list but is not counted in the totals. Uses OpenFEMA data but is not endorsed by or affiliated with FEMA.
