Hurricanes Harvey, Irma and Maria (2017)

Hurricanes Harvey, Irma, and Maria in Texas, Florida, Puerto Rico, and the United States Virgin Islands (USVI) caused severe flooding and high winds, resulting in damage to houses, critical facilities, schools, and other buildings. The advisories below provide information to assist with rebuilding decisions in the aftermath of the 2017 hurricanes as well as any future flooding or high wind events. This guidance is intended for homeowners, designers, building owners and officials, architects, engineers, and contractors; however, can provide helpful information for other stakeholders as well.
