Cole Creek Stabilization – St. Charles, MO

City of St. Charles

When high groundwater triggered a slide in the ±18 foot high bank along Cole Creek, the adjacent sanitary sewer and residences were threatened. The City of St. Charles retained Reitz & Jens to study alternatives and prepare construction documents to stabilize the reaches of Cole Creek where the bank had failed. A geotechnical investigation, including geotechnical borings, piezometer readings, and lab testing, was performed to obtain information for slope stability analysis. The recommendations provided by Reitz & Jens included stabilizing 400 linear feet of bank with a rock wedge and repairing 700 feet of a corrugated metal sanitary sewer using cured-in-place pipe liner. Additionally, Reitz & Jens obtained all necessary permits, including an individual 404/401 permit from the USACE and No Rise Certification for work in the regulatory floodway.
