"In order to qualify for FY 2011 funding, all grantees shall develop and maintain a THIRA."
"Current State Hazard Identification and Risk Assessments developed for the purposes of Pre-Disaster Mitigation (PDM) or Hazard Mitigation Grant Program (HMGP) that have a terrorism component satisfy the FY 2011 SHSP and UASI requirement."
THIRAs are intended to be tools that allow organizations at all levels of government to identify, assess, and prioritize their natural and man-made risks. These assessments are meant to facilitate the identification of capability and resource gaps, and allow organizations to track their year-to-year progress to address those gaps. THIRAs should leverage existing hazard mitigation processes, but be conducted in a reasonably standard manner so that results may be incorporated into federal-level assessments. FEMA will use these assessments to develop regional planning assumptions and, working with its partners, identify and implement priority actions to address assumptions identified.
