This course provides information on retrofitting existing flood-prone residential structures using methods such as elevation, relocation, flood walls, wet and dry floodproofing. It covers NFIP policies, regulations, building codes and standards that govern retrofitting projects.
The course is designed for engineers, architects, floodplain managers, building code officials, and other building officials with knowledge in building science and private sector professionals from engineering firms.
