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 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.

2016 Fall Flooding in Iowa (2017)

The following five Recovery Advisories were developed by the FEMA Mitigation Assessment Team (MAT) that responded to and studied damage from the 2016 Flooding in Iowa. They present mitigative measures that can and have implemented to minimize damage to residential buildings and critical facilities subject to riverine flooding. A list of the RAs is provided below:

RA 1 – Elevating Floodprone Buildings Above Minimum NFIP Requirements
RA 2 – Elevating Residential Structures within Special Flood Hazard Areas
RA 3 – Flood Protection for Critical and Essential Facilities
RA 4 – Flood Protection and Elevation of Building Utilities
RA 5 – Flood Protection for Backup and Emergency Power Fuel Systems

FEMA P-1020, Tornado: Moore, Oklahoma, May 20, 2013 Formal Observation Report

This formal observation report presents the observations, conclusions, and recommendations in response to field investigations conducted after the EF-5 tornado that impacted Moore, Oklahoma, on May 20, 2013. The post-storm investigation team focused its efforts on safe rooms and storm shelters in the path of the tornado in order to analyze their performance, functionality, and use. The report can be accessed and downloaded from the FEMA Library

FEMA P-942, Hurricane Sandy MAT Report

The Hurricane Sandy Mitigation Assessment Team Report documents observations made during field visits conducted by the Mitigation Assessment Team (MAT), specifically deployed to evaluate key building damage caused by Hurricane Sandy. It goes on to present the conclusions and recommendations derived from the field observations with regards to key engineering concepts, codes and standards, mitigation measures and considerations that can be used in the planning and recovery process to help minimize future damage to structures and their related utility systems.

The recommendations for disaster-resistant practices in hurricane-prone regions presented in the report are applicable to planners; decision makers; designers; contractors; building officials; federal, state and local government officials; building owners and operators; emergency managers and homeowners.

Observations, conclusions, and recommendations related to the following topics are included in the report:

  • Building Codes and Standards
  • Flood Protective Measures
  • Residential Construction
  • Critical Facilities and Key Assets
  • Mechanical, Electrical, and Plumbing Systems

FEMA P-942 can now be accessed and downloaded for free from the FEMA Library.

FEMA P-938, Hurricane Isaac MAT Report

The FEMA P-938 MAT Report was developed by the Mitigation Assessment Team (MAT) deployed to evaluate the damage caused by Hurricane Isaac and post-Hurricane Katrina construction and reconstruction efforts. It offers guidance intended to provide decision makers with information and technical guidance that can be used to reduce future hurricane damage. can Tbe report can be downloaded from the FEMA Library.

This MAT provided a unique opportunity to visit a location that was previously studied by a MAT (Hurricane Katrina MAT). The MAT report presents the team’s observations and subsequent recommendations based on the post-disaster damage assessments conducted in Louisiana. Some topics covered in the report include:

The performance of post Katrina residential construction and mitigation measures

  • Impacts to Emergency Operations Centers and other critical facilities
  • The performance of electrical distribution and communication facilities
  • A detailed review of codes and ordinances in the affected areas, with specific recommendations for improvement
