Colorado River Bank Stabilization
Mesa County, Colorado
Western Water & Land was retained by a local municipality for a riverbank stabilization project in Mesa County, Colorado. The stabilization effort was required to mitigate damage caused by flood-level flows in the Colorado to the riverbank along a 1,000-foot reach of the river adjacent to a municipal park. Western Water & Land was responsible for selection and design of the appropriate mitigative measures, coordination with the U.S. Fish and Wildlife Service (USFW) and the U.S. Army Corps of Engineers (USACE), technical oversight of the installation of the measures, and post-installation monitoring.
The purpose of the project was to construct a riverbank revetment system that will protect the riverbank from future erosion and degradation from river currents associated with and exceeding ordinary high river discharge events. The system was designed to be structurally sound, able to withstand high river current velocities, aesthetically acceptable, safe to the public, of modest cost, and allow river access/egress. The system included modification of the riverbank slope to form a stable configuration, installation of filter fabric and bedding material on the graded slope, placement of riprap rock to stabilize and protect the riverbank, and planting of willows and cottonwoods in the bank zone between the ordinary low and high water lines to promote long-term riverbank protection. Piezometers were installed to allow monitoring of groundwater levels beneath the protected riverbank.
