1964 – Branch within SPK Engineering Division.
1965 – Division within SPK (under Commander).
1971 – Organization assigned to SPD Commander.
1978 – Briefly FOA reporting to Director of Civil Works, then assigned to the Water Resources Support Center, a new FOA reporting to Director of Civil Works (CECW).
2000 – Assigned to Institute for Water Resources, an FOA/support office reporting to CECW.

HEC Basic Precepts‘HEC Business Model’
HEC exists to help the Corps perform it’s CW mission in a world-class manner.
The work of the Corps is performed at the field office level.
HEC products and services are for field use and application.
HEC is a wholly owned (by CECW) small business with primary customer base being the field offices; to lesser extent, HQUSACE, Labs, other Corps and Army elements, and other agencies/partners.

Certification of Levee Systems for the NFIP (EC 1110-2-6067)
Focus is on the levee system that is associated with a given separable floodplain.
A levee system is inclusive of all components that are interconnected and necessary to insure protection of the associated floodplain – levee/floodwall sections, closure structures, pumping stations, culverts, interior drainage works, and system operation and maintenance
No PARTIAL system certifications
