1. Background

The Robert T. Stafford Disaster Relief and Emergency Assistance Act, as amended and related authorities, as of June 12, 2019, authorizes the U.S. Department of Homeland Security (DHS) Federal Emergency Management Agency (FEMA) to provide alternative transportable temporary housing units (ATTHUs), acquired by purchase or lease, directly to individuals or households who, because a lack of available housing would be unable to make use of financial assistance. The Stafford Act also describes the decision criteria for determining which types of assistance will be provided; Stafford Act, Section (408) (b)(2)(B). Considerations include cost effectiveness, convenience to the individuals and households, and other factors the President may deem appropriate.

2. General

The effects of the August 2023 wildfire impacted the State of Hawaii causing widespread damage throughout large portions of the State. On August 10, 2023, President Biden issued a Major Disaster Declaration for Hawaii, designated as FEMA-DR-4724-HI, that authorized Individual Assistance (IA) for one (1) county in the State after the wildfire devastated State infrastructure in the impacted the county. The event exceeded State and local resource capacity. In response to this disaster, the Federal Emergency Management Agency (FEMA) was entrusted with procuring temporary housing for disaster survivors. Beginning in 2023, FEMA began coordinating temporary housing in the form of ATTHUs to accommodate those affected. Other Hawaii counties may be added and included in this Performance Work Statement (PWS) in the future. All direct housing options are authorized under Section 408 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act as amended (Stafford Act).

3. Scope
