American Society of Civil Engineers - Flood Resistant Design and Construction
The American Society of Civil Engineers maintains ASCE 24, a referenced standard in the I-Codes. ASCE 24-14 is referenced in the 2015 International Building Code® (IBC) and the 2015 International Residential Code® (IRC). ASCE 24-05 is referenced in the 2012, 2009, and 2006 IBC and IRC. Buildings and structures within the scope of the IBC proposed to be constructed in flood hazard areas must be designed in accordance with ASCE 24. The IRC requires dwellings in floodways to be designed in accordance with ASCE 24 and permits use of ASCE 24. The 2015 IRC permits use of ASCE 24 for dwellings in any flood zone, while earlier editions permit its use in Zone V and Coastal A Zones. The requirements of ASCE 24 meet or exceed the NFIP requirements for buildings and structures in special flood hazard areas. Separate documents summarizing ASCE 24-05 and ASCE 24-14 include the following topics: Building Performance; Flood-Damage Resistant Materials; Utilities and Service Equipment; and Siting Considerations.
