Modeling and Mapping Non-Accredited Levees: Dividing Levee Systems into Multiple Reaches
The Federal Emergency Management Agency (FEMA) has developed a new set of procedures for analyzing and mapping flood hazards on the landside of non-accredited levee systems on Flood Insurance Rate Maps (FIRMs). FEMA’s new procedures allow a levee system to be segmented into multiple reaches for analysis and mapping purposes.
This fact sheet summarizes how the new procedures can be combined to map an entire levee system. FEMA’s new procedures develop a more realistic determination of flood hazards by dividing a levee system into multiple reaches for analysis.
