When it is clear that State/Tribal capabilities will be exceeded, the Governor or Indian Tribal Government Chief Executive may request Federal assistance. In such cases, the affected local jurisdiction, tribe, State, and the Federal Government will collaborate to provide the necessary assistance. The Federal Government may provide assistance in the form of funding, resources, and critical services.

Once all supporting groups are assembled, the local emergency program manager works with tribal, State, and Federal personnel in an expanded damage assessment. An estimate of the type and extent of Federal disaster assistance will come through this joint assessment.
