Corps Levee Certification Policy

The basic policy governing levee certification for the National Flood Insurance Program (NFIP) was issued by the Federal Emergency Management Agency in 1986 as 44 CFR 65.10. This policy requires complete engineering analysis of hydrology, hydraulics, structural and geotechnical, and operations and maintenance of the levee undergoing study for certification determination.

Corps Authority and Funding

The Corps of Engineers does not have a specific authority that addresses levee certifications nor is it funded for levee certifications. Certification of levees for the National Flood Insurance Program is the responsibility of the local levee owner or sponsor. There may be a few cases in which the Corps can perform a certification, for example if the levee is part of an ongoing Corps project.  In many cases, however, the Corps' Levee Safety Program activities will help inform and support the certification process.  Corps districts are working with local levee owners to provide them with available levee information and technical data. 

Corps Technical Guidance

The draft Engineer Technical Letter (ETL) 1110-2-570 provides a consolidated document of USACE procedures for levee/floodwall systems certification determinations in support of the National Flood Insurance Program as administered by the Federal Emergency Management Agency (FEMA). The Engineer Technical Letter will be used to respond to requests for local sponsor levee systems certifications.
