The Chatfield Reservoir Mitigation Company (CRMC) partnered with Western States Reclamation, Inc. as the landscape and habitat restoration contractor as part of a $45 million Construction Management at Risk (CMAR) contract for several major phases of the Chatfield Storage Reallocation Project. The project consisted of the reallocation of 20,600 acre-feet of flood storage space in Chatfield Reservoir by the U.S. Army Corps of Engineers (USACE), for municipal, agricultural, and other beneficial uses. The project limits were confined within the 5,400-acre Chatfield State Park, owned by USACE, and managed operated by the Colorado Parks and Wildlife. Chatfield State Park remained open to the public during construction, which required an extensive planning and phasing effort to assure public satisfaction and safety.
The scope of work given to Western States was an extensive stream habitat restoration and revegetation plan, consisting of beaver dam construction, planting over 140,000 deciduous and evergreen trees, shrubs, wetland plugs, willow stakes, and cottonwood poles. Other project elements involved the use of several designed seed mixes with appropriate soil amendments and hydraulic mulches on approximately 350 acres of wetland and upland environments. Additionally, Western States installed over 100,000 square yards of coir matting, erosion control blanket, and harvested and assembled 8,600 linear feet of willow logs for stream bank stabilization.
This project was the winner of the 2020 Sustainability category as part of the annual Elite Awards given by the Associated Landscape Contractors of Colorado.Learn More
