How to read these FEMA records
- Declaration and program designations follow the OpenFEMA extract dated November 6, 2026. County matches require the declared county code and a matching place name. The original declaration date anchors elapsed-time calculations. Local program designations may have changed after that date.
- Household figures combine available owner or renter registration buckets within a declaration and county. The approved amounts come from FEMA’s Individuals and Households Program data. A figure covers published buckets with consistent registration counts and amounts.
- The project snapshot was refreshed by FEMA on November 10, 2026. Its federal share is the amount FEMA obligated to a public-assistance recipient for approved work. Applicant geography describes the organization’s location or statewide classification. First and last obligation dates describe grant records.
- Project timelines use matching worksheet and applicant IDs. Each version’s signed amount comes from FEMA grant award activity, which contains entries through November 10, 2026. Negative entries reduce the recorded obligation. A worksheet may have later accounting activity after the project snapshot.
