This Engineering and Construction Bulletin (ECB) directs that USACE cease using EC 1110-2-6067 (reference 1.c.) for all new levee evaluations for NFIP mapping purposes initiated after the date of issuance and begin using the process set forth in Appendix B of this ECB or successor guidance. As USACE and FEMA move to risk-informed levee evaluation processes, this ECB provides guidance explaining how to transition USACE Levee System Evaluation Reports (LSERs) from the process set forth in EC 1110-2-6067 to USACE accreditation recommendations using risk assessments as outlined in Appendix B.
