Drainage System Stabilization Project case study
In 1997, a residential development was built upslope from this golf course drainage ditch. It began to erode, but because the ditch was filled with invasive species such as Blackberry and Reed Canary Grass, the erosion was not visible.
When the non-native plants were removed to create a new golf course hole, the erosion was evident – in some places more than four feet deep, all the way down to the hard clay bottom.
The Envirolok Vegetated Retaining Wall system was used for both the sides and bottom of the ditch. It was installed and woven together with bag stabilizer strips to prevent rushing water from compromising the structure.
