The focus of this manual is the retrofitting of one- to four-family residences subject to flooding situations without wave action. The manual presents various retrofitting measures that provide both active and passive efforts and employ both dry and wet floodproofing measures. These include elevation of the structure in place, relocation of the structure, construction of barriers (floodwalls and levees), dry floodproofing (sealants, closures, sump pumps, and backflow valves), and wet floodproofing (flood damage-resistant materials and protection of utilities and contents).
