Abstract: This paper sets forth a new damage scale for use in assessing physical damage to single family houses caused by wind and flood events. A new methodology is presented for assessing both structural and nonstructural physical damage caused by flood events, ranging from slow-rise inundation flooding to coastal high velocity flooding with wave action. The flood scale is integrated with FEMA’s HAZUS wind damage scale to allow users to assess a building’s overall level of physical damage on a loss-consistent basis. The damage scale additionally expands and improves FEMA’s HAZUS wind damage scale by including two new categories to assess more severe levels of damage. This combined wind and flood damage scale (the WF Damage Scale) ranges from WF-0 (no damage to very minor damage) to WF-6 (complete collapse). Qualitative and quantitative damage descriptions are provided to ease field implementation.
