Final answer:
Use the BFE from the current FIS to determine the flood protection level for a new home at Site N, as it is the official measure until the new study is finalized and adopted.
Step-by-step explanation:
To determine the flood protection level for a new home at Site N, the Base Flood Elevation (BFE) from the current Flood Insurance Study (FIS) must be used. This is because the preliminary study and the restudy have not been finalized, and regulations typically require that the current, officially adopted BFE be used for planning and construction purposes. The BFE from the current FIS is the official measure until the new study is adopted by the local community and the Federal Emergency Management Agency (FEMA).
