In September 2013, the Colorado Front Range experienced a large flood event that ravaged rivers, communities, and infrastructure, damaging and destroying large sections of highways, local roads, and public, residential, and commercial properties. Larimer County Road 43 (CR 43) was heavily damaged as a result of flooding and erosion. River restoration activities were conducted along most of the North Fork of the Big Thompson River where the river runs adjacent to the roadway.
Channel reconstruction activities were cost-effective due to collaboration between entities; materials, equipment, manpower, and expertise were leveraged from the highway reconstruction efforts in order to restore the river channel for the benefit of both the river and roadway.
Strategic placement of boulders, rock structures, and large wood were used in a comprehensive and holistic approach to the rehabilitation of the channel and its floodplain, in a coherent, consistent restoration project.
