As part of the ongoing Duluth Lakewalk revitalization, the Canal Park beach required redesign following the 2017 and 2018 storms, which caused significant damage to the area and flooding that impacted the infrastructure behind it.

AMI Consulting Engineers conducted topographic surveys of the Duluth shoreline, from the taper of the lakewalk armor stone revetment up to the adjacent seawall. AMI prioritized shoreline stabilization and rehabilitation of the beach area due to significant erosive damage, using cobblestone, beach rock, and sand to create a new beach capable of withstanding the forces of wind and water.

Strong, durable armor stones along the shoreline help break up waves and preserve the beach’s natural aesthetic. AMI engineers designed the 2,890 LF seawall behind the armor stones to aid in wave dispersion, leaving seven sections open for public access to the beach. The two widest openings, at either end, are protected by carefully placed armor stones to mitigate wave action.

AMI provided construction oversight and inspections throughout the six-month project, along with guidance on armor stone sizing, erosion control measures, stormwater design, and engineered additional solutions that regained the structural integrity of the coastal shoreline, while working closely with TRC Companies and the City of Duluth. AMI also kept up with all environmental regulations and halted work from September 15 to June 30, as needed for fish spawning and migration windows.

This combination of design, durability, and a focus on preserving the natural beauty of Duluth’s shoreline resulted in a safer, more inviting beach area for the community to enjoy
