The following documents provide information concerning the flood resistant provisions of the 2015, 2012, and 2009 International Codes® (I-Codes), the referenced standard American Society of Civil Engineers (ASCE) 24, Flood Resistant Design and Construction, and the National Flood Insurance Program (NFIP) requirements.
This document is a compilation of flood resistant provisions, prepared by the Federal Emergency Management Agency (FEMA), of the 2015 I-Codes (IBC, IRC, IEBC IMC, IPC, IFGC, IPSDC, IFC). Also included, as a separate document, is a summary of changes from the 2012 I-Codes. The 2015 edition of the I-Codes contains provisions that are consistent with the minimum flood-resistant design and construction requirements of the NFIP for buildings and structures. See link below for Highlights of ASCE 24-14 (ASCE 24-14 is a referenced standard in the 2015 IBC and IRC).
This document is a compilation of flood resistant provisions, prepared by FEMA, of the 2009 I-Codes (IBC, IRC, IEBC IMC, IPC, IFGC, IPSDC, IFC). Also included, as a separate document, is a summary of changes from the 2006 I-Codes. The 2009 edition of the I-Codes contains provisions that are consistent with the minimum flood-resistant design and construction requirements of the NFIP for buildings and structures. See link below for Highlights of ASCE 24-05 (ASCE 24-05 is a referenced standard in the 2009 IBC and IRC).
ASCE 24-14: The American Society of Civil Engineers (ASCE) 24-14 is a referenced standard in the 2015 International Building Code® (IBC) and the 2015 International Residential Code® (IRC). Building and structures within the scope of the IBC proposed to be constructed in flood hazard areas must be designed in accordance with ASCE 24-14. The IRC requires dwellings in floodways to be designed in accordance with ASCE 24-14 and includes an alternative that allows communities to require homes in any flood zone to be designed in accordance with ASCE 24-15. Highlights of ASCE 24-14 that complement the NFIP minimum requirements include: Building Performance; Flood-Damage Resistant Materials; Utilities and Service Equipment and Siting Considerations.
ASCE 24-05: The American Society of Civil Engineers (ASCE) 24-05 is a referenced standard in the International Building Code® and International Residential Code® (editions published 2012, 2009 and 2006). Building and structures within the scope of the IBC proposed to be constructed in a flood hazard area must designed in accordance with ASCE 24. The IRC requires that dwellings in floodways to be designed in accordance with ASCE 24, and the 2012 and 2009 editions include an alternative that allows communities to require homes in Zones V to be designed in accordance with ASCE 24. Highlights of ASCE 24 that complement the NFIP minimum requirements include: Building Performance; Flood-Damage Resistant Materials; Utilities and Service Equipment; and Siting Considerations.
Developed by the International Code Council and FEMA, this guide helps State and local officials integrate the International Codes® (I-Codes) into their current floodplain management regulatory processes related to structures, buildings, and other development in special flood hazard areas in order to meet the requirements to participate in the NFIP. Chapter 2 describes three approaches for coordinating the I-Codes and local floodplain management regulations and identifies a number of advantages and considerations when relying on the flood provisions of the codes. Chapter 3 explains several differences between the NFIP regulations and the I-Code requirements related to specific terminology and provisions. Many requirements in the codes exceed NFIP minimum requirements, and some provisions are more specific than the NFIP, especially in the International Building Code®, which references ASCE 24, Flood Resistant Design and Construction. Chapter 4 contains questions for States and communities to answer to know whether and how to modify existing floodplain management regulations to coordinate with the I-Codes. Chapter 5 describes modifications that can be adopted to incorporate higher standards in the I-Codes to further increase resistance to flood damage. Chapter 6 introduces model code-coordinated ordinances prepared by FEMA.
These checklists can be used to guide floodplain managers, building officials and designers as they compare the flood provisions of the 2009 and 2012 I-Codes and ASCE 24-05 to the minimum requirements of the NFIP. It is based on the standard checklist used by FEMA and states to review local floodplain management regulations/ordinances to determine whether such regulations and ordinances are complete for the purpose of participating in the NFIP..
This guide illustrates the similarities and highlights the differences between the National Flood Insurance Program (NFIP) minimum requirements and the requirements of the International Code Series (I-Codes) and ASCE 24, Flood Resistant Design and Construction (ASCE 24), a standard referenced by the I-Codes. The illustrations highlight some of the key similarities and differences between foundation types, lowest floor elevations, enclosures below elevated buildings and utilities requirements contained within the NFIP and I-Codes for most residential and commercial buildings (classified as "Category II" structures by the building codes).
This document contains Flood Resistant Provisions of the 2012 editions of codes published by the International Association of Plumbing and Mechanical Officers (IAPMO): the Uniform Mechanical Code; Uniform Plumbing Code, Uniform Swimming Pool, Spa and Hot Tub Code and Uniform Solar Energy Code.
CodeMaster for Flood Resistant Design (2011)
The CodeMaster provides designers with an easy-to-use desk reference that identifies the flood provisions in the 2009 and 2012 International Building Code® (IBC®) and International Residential Code® (IRC®), as well as the flood requirements of American Society of Civil Engineers (ASCE) standards 7-05, 7-10 and 24-05. The CodeMaster is a unique and useful tool for designers to make sure that they incorporate the flood-resistant provisions of these codes and standards. The 8-page guide provides sections on preliminary considerations and design process, key flood terminology, a 12-step process to incorporate flood resistance in the design of a building, an example showing the 12-step process being executed and information on additional FEMA mitigation resources related to flood-resistant design. The document also uses illustrations to ensure a clear understanding for users in the professional community.
This sub-study evaluates the NFIP building standards, including a review of flood loss and damage data for structures and communities and calculation of costs and benefits of modifying NFIP building standards across defined ranges of flood conditions and building configurations, differentiated by flood hazard zone.
This document provides a supplement analysis to the 2006 Evaluation of the National Flood Insurance Program’s Building Standards. The purpose of this document is to determine the cost-effectiveness of including freeboard within the foundation height of new residential buildings constructed in floodplains and to establish which factors should be considered when determining how many feet above the minimum NFIP-required elevation a house should be constructed in order to maximize cost-effectiveness.
