The U.S. Army Corps of Engineers – Omaha District (USACE-NWO) covers about 700,000 square miles of the U.S. Great Plains, spanning from Montana to the Great Lakes. USACE maintains an inventory of about 2,000 levee systems or 14,000 miles of levees nationwide. Levee systems change over time and require continual inspection and repair to maintain their original functionality.
USACE-NWO implements a Periodic Inspection program to inspect federally authorized levees every five years to monitor the overall condition, identify deficiencies, and confirm maintenance activities.
RJH has performed periodic inspections of over 20 levee systems located in Iowa, Montana, Nebraska, and South Dakota. The system includes over 60 miles of levees, flood damage reduction channels, pump stations, and floodwalls. RJH personnel compiled existing system documentation, evaluated design criteria against current standards, prepared pre-inspection packets, conducted field inspections to identify and map operational and safety concerns, prepared inspection reports, and recommended remediation actions. Eight of the levee systems included inspection and evaluation of levees that were more than 20 feet tall and more than 10 miles long. Our team also performed electrical and mechanical engineering inspections of pump stations in the levee systems.
