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 California'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.
