Dry floodproofing can be described as a combination of operations plans, adjustments, alterations, and/or additions to buildings that lower the potential for flood damage by reducing the frequency of floodwaters entering the structure. When dry floodproofing is an option, the most obvious advantage is that flood waters remain outside the home elimination the physical damage and contamination that go with flooding. Many homes are not candidates for dry floodproofing due to floatation forces, space constraints and other reasons covered in this course. This course helps determine which homes are candidates for dry flood proofing.

This course is based on the FEMA publication, Engineering Principles and Practices for Retrofitting Flood-Prone Homes, Chapter 5 Dry Floodproofing and the case study on the Borges residence from Chapter 6 of the same document.
