  • Product: ArmorLoc® Class 5011
  • Area: 79,500 sf
Winter 2002

The Mill Creek Conservancy District needed to protect a stretch of creek 2,500-ft. in length. This area handled a significant portion of stormwater runoff which came from the northern downtown section to the Ohio River, approximately six miles away.

The project included the slight clearing and widening of an existing intercity channel to provide a greater capacity of controlled water flow. The U.S. Army Corps of Engineers permitted and designed the protection method. The solution included ArmorLoc 5011 articulating concrete block (ACB) mats to be hand-placed along the stream banks. Turf Reinforcement Mats were used in addition to the hard armor and placed above the heavy flow line and woody vegetation.

A total of 79,500 sf of the hand-placed ACB revetment mats were installed. Natural soils were backfilled into the ArmorLoc units’ open cells providing the perfect environment for healthy vegetation. With the ease of installation, only three months were needed to complete the entire project.
