Abstract. On 10 September 2017, Hurricane Irma made landfall in the Florida Keys and caused significant damage. Informed by hydrodynamic storm surge and wave modeling and post-storm satellite imagery, a rapid damage survey was soon conducted for 1600+ residential buildings in Big Pine Key and Marathon. Damage categorizations and statistical analysis reveal distinct factors governing damage at these two locations. The distance from the coast is significant for the damage in Big Pine Key, as severely damaged buildings were located near narrow waterways connected to the ocean. Building type and size are critical in Marathon, highlighted by the near-complete destruction of trailer communities there. These observations raise issues of affordability and equity that need consideration in damage recovery and rebuilding for resilience.

Short summary
On 10 September 2017, Hurricane Irma made landfall in the Florida Keys and caused significant damage. To better understand the hurricane's damage to the Florida Keys, we first conducted hydrodynamic storm surge and wave modeling. By checking the surge hazards and post-damage satellite data, we determined the places to conduct detailed on-site surveys. We assessed 1600+ damaged residential buildings in Big Pine Key and Marathon. A statistical model is developed to understand damaging factors.
