University Streambank

The University had an eroding stream bank adjacent to a road and parking lot. Due to the proximity of the streambank to the roadway, a steep slope was required. The design team selected a vegetated concrete block mat over rip rap due to the steepness of the slope and the velocity of the stream. Using a concrete block mat also reduced the amount of re-grading. The slope was re-graded to a 1.5:1 slope.

The protected area was approximately 100' long and the slope lengths ranged from 20' to 35'. The concrete block mat selected for this project was Flexamat Standard. Rolls were precut at the manufacturing plant to site specific custom lengths. The area was seeded prior to the concrete mat installation. Once the material was installed, Willow live stakes and plugs were planted to expedite vegetation within the concrete matting.
