One of the most common of all retrofitting techniques is to raise an entire existing superstructure above the Design Flood Elevation (DFE). When properly done, the elevation of the home places the living area above all but the most severe floods.<\/p>\n
Elevating the structure allows water to enter the building footprint while locating the living area above the anticipated flood elevation. Elevating the home offers long term advantages over wet floodproofing by making the cleanup after the flood much easier limiting the cleanup to areas outside of the living area. In many cases, elevating the home is simpler and more cost effective than dry floodproofing. This information in this course could be useful in projects where elevating a home is necessary, regardless of the reason.<\/p>\n
This course includes a multiple-choice quiz at the end and is intended to provide 5 hours of professional development.<\/p>\n
This course is based on the FEMA publication, Engineering Principles and Practices for Retrofitting Flood-Prone Residential Structures, Chapter 5E Elevation and Case Study No. 2 from Chapter 6. It is intended to provide knowledge that may be used to protect residential structures from flooding by raising the living area above the DFE.<\/p>\n
