This dataset lists properties from completed acquisition projects funded under the Hazard Mitigation Grant Program (HMGP). The HMGP provides grants to states and local governments to implement long-term hazard mitigation measures after a major disaster declaration. Acquisition projects funded under the Hazard Mitigation Grant Program (HMGP) are voluntary and one is under no obligation to sell their home. Acquisition projects are based on the principle of fair compensation for property. Property acquisitions present owners with an opportunity to recoup a large part of their investment in property that probably has lost some, if not most of its value due to damage after a disaster. Under the Stafford Act, any land purchased with Hazard Mitigation Grant Program funds must be restricted to open space, recreational, and wetlands management uses in perpetuity

Acquisition or Buyout projects, while 75 percent funded by FEMA, are administered by the State and local communities. FEMA does not buy properties directly from the property owners. Communities may offer homeowners who agree to participate in a buyout project up to the fair market value of the home before the disaster struck. A licensed appraiser hired by the community determines the fair market value. No one is obligated to sell their home; these are transactions and prices that both the property owner and communities agreed on. For More information on HMGP please visit

Missing values - In some cases the projects are closed and the data was simply not provided by the sub-grantee or the Grantee and/or entered into the HMGP system. It is likely available as part of the paper file which is considered the file of record. While it is strongly encouraged, it is not required for this data to be provided in the HMGP system for the project to be closed out.
