The NFIP Technical Bulletin 4 from June 2019 provides guidance on the National Flood Insurance Program (NFIP) floodplain management requirements for installing elevators and associated equipment below the base flood elevation (BFE) in Special Flood Hazard Areas (SFHAs). The document discusses the types of elevators, types of elevator systems, and practical methods to protect elevators from flood damage. It also covers how elevators impact NFIP flood insurance rates, NFIP and other regulations, and mitigation guidance based on post-disaster observations.
