Adie West of Schuetz

Location: Maryland Heights, Mo.

Client: City of Maryland Heights

Completion Date: June 2001

Urbanization of the watershed had caused increased flow in Fee Fee Creek in Maryland Heights, Mo. Typical of most creeks in urbanized areas, it incised the channel bed with steep channel banks. This project focused on the bank erosion along commercial buildings on both sides of the creek. The eroding banks were threatening the parking lots and utility poles.

Reinforced composite revetment was selected to stabilize the creek banks and grade control structures were placed in the creek to prevent further bed incision. The reinforced composite revetment was composed of layers of geogrid in the banks with rock riprap placed on the bank face. Plantings were installed in lifts between the rock riprap. The plantings are instrumental in adding roughness to the bank and providing additional reinforcement. Adding roughness on the creek bank helps slow the velocity and prevent erosion.

  • Hydraulic modeling
  • Reinforced channel banks
  • Grade control structures
  • 404 permit
  • Easements
  • Plantings

A 404 permit was obtained from the U.S. Army Corp of Engineers, St. Louis District, for this project, and another from the Metropolitan St. Louis Sewer District (MSD). Hydraulic modeling of the proposed improvements was performed to ensure that the improvements would not raise the stage of the creek. Temporary and permanent easements were obtained from the property owners. Coordination with utility companies prevented conflicts with facilities.
