• Accredited Levee System - A FEMA accredited levee system is a levee system that meets the requirements of 44CFR65.10 and therefore is shown on the Flood Insurance Rate Map (FIRM) as providing protection from the 1-percent-annual-chance flood.

• FEMA does not own, operate, maintain, or inspect levee systems or develop certified levee-related data for accreditation purposes.

FEMA Accreditation


• As the levee owner, USIBWC will evaluate that the levees have been constructed to required design standards and are operated appropriately.

• For FEMA to accredit a levee system with 1%-annual-chance flood hazard reduction capability on a FIRM, the levee owner/local project sponsor must submit a package containing the required data and documentation to show that the levee system meets all design and operation requirements of 44CFR 65.10.

FEMA Accreditation


• Interior Drainage - FEMA requires an Interior Drainage Analysis. To date, no analysis exists. USIBWC is only authorized to do work on the levees within USIBWC ROW and does not have authority in assessing the interior drainage issues.

• Levees need to tie into high ground• Levee/Roadway intersections • Intake / Drainage Channels
