Final answer:
The requirement for elevation above the BFE when replacing an old manufactured home with a new one depends on factors such as building specifications and local regulations. Consultation with local authorities and professionals is necessary to determine the specific requirements.
Step-by-step explanation:
If an old manufactured home is replaced with a new one on the same foundation, the requirement for elevation above the BFE (Base Flood Elevation) will depend on several factors. The BFE is determined by FEMA (Federal Emergency Management Agency) and represents the estimated height floodwaters could reach during a 100-year flood event. If the new home is built to the same specifications and meets all the relevant building codes, it may not need to be elevated. However, if the new home is built with different specifications or the local regulations have changed, it may be necessary to elevate it above the BFE to ensure the safety of the structure. It is important to consult with local authorities and professionals knowledgeable in floodplain management and building codes to determine the specific requirements for the replacement home.
