- Introduction
- The Federal Emergency Management Agency (FEMA), through the Building Science Branch of FEMA’s Federal Insurance and Mitigation Administration (FIMA), deployed Mitigation Assessment Teams (MATs) to Texas, the U.S. Virgin Islands (USVI), Puerto Rico, and Florida in 2017 after Hurricanes Harvey, Irma, and Maria. The teams developed four MAT reports summarizing building performance observations, recommendations, and technical guidance for rebuilding:
- 1.1 Organization of the Report
- 1.2 Purpose and Background
- 1.3 Background of the Events
- 1.3.1 Hurricane Harvey
- 1.3.2 Hurricane Irma
- 1.3.3 Hurricane Maria
- 1.4 FEMA Mitigation Assessment Team Performance and Data Collection
- Building Codes, Standards, and Regulations
- To better understand how buildings were constructed, the MAT reviewed building code histories, floodplain management regulations, and reference standards in the areas impacted by the 2017 hurricanes. Understanding the codes, regulations, and standards helped the MAT identify which building techniques performed well in extreme conditions and which needed improvement.
- 2.1 Relationship between Regulations, Building Codes, and Design Standards
- 2.2 State- or Territory-Specific Building Codes, Standards, and Regulations
- 2.2.1 Texas
- 2.2.2 USVI
- 2.2.3 Puerto Rico
- 2.2.4 Florida
- Building Performance
- The MATs observed damage to buildings, building equipment, and associated structures caused primarily by flooding and high winds from the three hurricanes. While observing building-related damages, the MATs also inspected certain building performance issues in detail. This chapter is structured to present flood and wind hazard damages, as well as the impacts of these damages on different building types.
