Hazard Mitigation, Section 406, is a funding source for cost-effective measures that would reduce or eliminate the threat of future damage to a facility damaged during the disaster. The measures must apply only to the damaged elements of a facility rather than to other, undamaged parts of the facility or to the entire system.
For example, if flooding inundates a sanitary sewer and blocks the manholes with sediment, mitigation to prevent the blockage of the damaged manholes in a future event may be considered eligible. However, work to improve undamaged manholes using the same method would not be eligible, even though the manholes are part of the same system.
Hazard mitigation measures restore a facility beyond its pre-disaster design. Section 406 mitigation measures are considered part of the total eligible cost of repair, restoration, reconstruction, or replacement of a facility. They are limited to measures of permanent work, and the Applicant may not apply mitigation funding to alternate projects or improved projects if a new replacement facility is involved. Upgrades required to meet applicable codes and standards are not "mitigation measures" because these measures are part of eligible restoration work.
