This Minnesota Department of Natural Resources project is a link in the new state trail system between Detroit Lakes, MN and Frazee, MN. In the process, Bolander stabilized a 40’ tall slope directly between Acorn Lake and Highway 10. Accessing this job was no easy task; prior to starting, Bolander designed a temporary access road along the lake which allowed issuance of a MnDNR work in waters permit. Once the trees were cleared and the access road installed, we worked along the lake shore to install a 440′ long sheet pile wall which was later enhanced

with over 100 tie-back anchors. Flanking the sheet pile were two big-block retaining walls, each over 200′ long. Above the trail, on the upper part of the steep slope, Bolander installed over 2500 percussion anchors in a large reinforced zone. Throughout the duration of the project, Bolander moved no less than 25,000 CY of soil and installed numerous storm water structures. Finally, the trail itself was paved, the site seeded and landscaped – now ready to connect visitors with the outdoors.
