Building Performance Observations, Recommendations, and Technical Guidance.

In response to a request for technical support from the Federal Emergency Management (FEMA) Joint Field Office in St. Croix, FEMA’s Federal Insurance and Mitigation Administration’s (FIMA) Building Science Branch deployed a Mitigation Assessment Team (MAT) composed of national and regional experts to affected areas in St. Thomas, St. John, and St. Croix, in October and November, 2017.

The MAT was charged with evaluating damage from Hurricanes Irma and Maria, especially for buildings constructed or reconstructed after Hurricane Marilyn (1995), to identify both successful and unsuccessful mitigation techniques. This work involved: assessing the performance of residential, nonresidential, and critical facilities affected by the storms; evaluating the performance of photovoltaic (PV) facilities; investigating the effects of wind speed-up due to the islands’ topography on building performance; and meeting with residents and local officials to better understand what transpired during and after the storms.
