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 to satisfy 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 that states and communities should answer to know whether and how to modify existing floodplain management regulations to coordinate with building codes.

Chapter 5 describes modifications that can be adopted to incorporate higher standards in State and local building codes that are based on the I-Codes to further increase building and community resilience to flood damage.

Chapter 6  introduces the model code-coordinated ordinances prepared by FEMA. The model ordinances are available at: http://www.fema.gov/media-library/assets/documents/96224.
