OUR PROJECT EXPERIENCE

USACE LEVEE INSPECTIONS

In support of the National Levee Safety Program, several employees of Prairie Engineers performed Periodic Inspections on multiple levee systems for the St. Louis District of the U.S. Army Corps of Engineers (USACE). These inspections are part of a nationwide effort to inventory federal program levees and to assess their conditions and capabilities.

Numerous flood protection systems comprising over 400 miles of levee on the Mississippi, Missouri, Illinois, and Kaskaskia Rivers were inspected including 33 pump stations and numerous closure structures and floodwalls. Infrastructure condition was evaluated and ratings were assigned within a nationwide GIS database for infrastructure management.

The purpose of the levee inspections is to verify proper operation and maintenance of levee components, evaluate operational adequacy, assess structural stability, review design criteria to identify changes in current design standards, identify which features to monitor over time, and to improve the ability of the USACE to communicate the overall condition of the levees.

Additionally, these inspections help the levee districts to re-evaluate their resource allocation to better maintain their systems. This information can also be used to assist in the accreditation of levee systems.
