The Incident Period is the time span during which the disaster-causing incident occurs. This period varies in length, depending on the type of incident. For example, the incident period for a flood event could be several weeks, because the water has to crest and recede; while the incident period for a tornado would be one day, because the damage occurs in a matter of minutes. Damage that occurs during the incident period, or damage that is the direct result of events that occurred during the incident period, is eligible. Protective measures and other preparation activities performed within a reasonable and justified time in advance of the incident period may also be eligible. The incident period will be established by FEMA in the FEMA-State Agreement.
