Levee / Floodwall Certification

Anderson Consulting Engineers staff is intimately familiar with the analyses required for levee/floodwall certification outlined in various Federal Emergency Management Agency (FEMA) and U.S. Army Corps of Engineers (USACE) guidelines, engineering manuals, and technical letters. Anderson Consulting Engineers staff has kept abreast of the USCAE’s ever-evolving levee certification guidance and design criteria by attending related national conferences, workshops, and webinars. Mr. Brad Anderson, the Principal of ACE, was a member of the Independent Technical Review Committee for the U.S. Army Corps of Engineer’s document “EC 1110-2-6067, USACE PROCESS FOR THE NATIONAL FLOOD INSURANCE PROGRAM (NFIP) LEVEE SYSTEM EVALUATION” [August 31, 2010]. This document contains the latest guidance from the USACE in the field of levee certification.




FEMA issued Procedure Memorandum 34 “Interim Guidance for Studies Including Levees” and Procedure Memorandum 43 “Guidelines for Identifying Provisionally Accredited Levees (PALs)” in August 2005 and September 2006 respectively. PMs 34 and 43 dramatically changed the way Digital Flood Insurance Rate Maps (DFIRMs) (see Floodplain Studies section) are scheduled and produced. Anderson Consulting Engineers was one of the first DFIRM contractors, to be exposed to the new levee accreditation process. Therefore, our understanding and experience with FEMA’s levee/floodwall accreditation program is unparalleled in the State of Colorado.  Since then ACE has been providing general education and outreach to levee/floodwall owners facing accreditation of their levees.  We provide the following general services leading to accreditation: certification needs assessments, inspections, certification evaluations (freeboard, closure/penetrations, and interior drainage), and compilation of the accreditation request to FEMA.  Additionally, ACE has been providing its specialized certification evaluations to fellow engineering firms supporting their accreditation efforts for levees/floodwalls.

The breadth ACE’s levee/floodwall experience is evidenced by the variety of projects completed involving: a) first time certifications of projects designed by others; b) recertification of projects previously accredited by FEMA; and c) certification support/accreditation education:
