SECTION 4: RISK ASSESSMENT
The HMPC also researched past events that resulted in a federal and/or state emergency or disaster declaration for Wake County in order to identify significant hazards. Federal and/or state disaster declarations may be granted when the Governor certifies that the combined local, county and state resources are insufficient and that the situation is beyond their recovery capabilities. When the local government‘s capacity has been surpassed, a state disaster declaration may be issued, allowing for the provision of state assistance. If the disaster is so severe that both the local and state government capacities are exceeded, a federal emergency or disaster declaration may be issued allowing for the provision of federal assistance. Records of designated counties for FEMA major disaster declarations start in 1964. Since then, Wake County has been designated in 11 major disaster declarations, as detailed in Table 4.3.
