Rehabilitation Of High Hazard Potential Dam (HHPD) Grant Program

The President signed the Water Infrastructure Improvements for the Nation Act or the “WIIN Act,” on December 16, 2016, which adds a new grant program under FEMA’s National Dam Safety Program (33 U.S.C. 467f). Section 5006 of the Act, Rehabilitation of High Hazard Potential Dams, provides technical, planning, design, and construction assistance in the form of grants for rehabilitation of eligible high hazard potential dams.

High Hazard Potential is a classification standard for any dam whose failure or mis-operation will cause loss of human life and significant property destruction.
