The Admiral Trost Wetland Development project began in 2018, with the city of Columbia, IL’s desire to transform a turf grass field near the Mississippi River into a wetland. Following a significant amount of earthwork, construction, and plant installation, coontinued stewardship has helped the area develop into a functioning ecosystem as well as a scenic park.
In 2020, the city of Columbia, MO began to transform approximately 26 acres of roadside and median sites throughout the city from mowed turf into native prairie, to create pollinator habitat along previously unutilized corridors. DJM has been responsible for stewardship of these developing areas as well as several established prairies since Spring of 2020.
For the Hermann Farm project, DJM self-performed a substantial amount of earth and civil work throughout the course of construction of a new pond and horse arena. This project involved mass excavation and grading, installation of culvert pipe and an inline water control structure, and construction of both Redi-Rock and stacked-stone boulder walls.
Since 2018, the Rock Island District of the U.S. Army Corps of Engineers has engaged DJM to perform a suite of forestry services across many Corps-owned sites. Scopes including invasive species control, timber stand improvement, tree planting, and seeding have occurred across 15+ locations, including river islands and wildlife management areas.
The L575 Buchanan-Atchison-Hamburg Levee System in Hamburg, Iowa experienced significant damage during a 2019 Flood Event, which led to seven breaches and substantial other damages throughout the 52 mile levee system. As USACE civil contractors were rebuilding and repairing the levee, DJM mobilized a crew that installed high performance turf reinforcement mat (HPTRM), which was secured with percussion driven earth anchors and soil pins.
DJM acted as the design-build contractor on this project, working with designer Dave Derrick, one of the nation’s premier potamologists, to improve and stabilize approximately one mile of the stream running through the Forest Hills Golf Course. DJM self-performed all construction and restoration work on the project, including earth moving, construction of engineered rock riffles and pools which created a more naturalized flow pattern for the stream, and rock revetment with native plantings on the streambanks for stabilization.
