Existing conditions of the 1.3-mile Magee Marsh Shoreline Protection Barrier.
KS Associates is under contract with the Ohio Department of Natural Resources (ODNR) for the Magee Marsh Shoreline Protection Barrier Rehabilitation. The goal of the project is to rehabilitate 1.3 miles of revetment along the shoreline of Lake Erie. This is the largest revetment project in KS Associates’ history. When constructed, the rehabilitated revetment will dissipate wave energy and prevent erosion of the berm that protects the wetlands landward.
KS Associates’ scope of work has included design, permitting, and construction administration services to repair the earthen embankment, filter and armor stone, and gravel access roads. KS Associates is currently providing construction inspection services.
Early in the project, KS Associates assisted ODNR with preparing conceptual-level opinions of probable costs for the repairs; developing a plan for phasing the project taking into consideration budgets and funding sources; developing a permitting strategy that outlined the required permits and timeframes for obtaining agency approvals; and creating implementation schedules for the design and construction of the project.
KS Associates submitted final design plans to ODNR two months ahead of schedule allowing the project to go out to bid two months early. An early delivery of plans and cross sections allowed the contractor to order and stockpile enough stone to keep the project supplied for the duration of construction. The early bid also trimmed the construction duration from approximately 14 months to 10 months. The 1.3-mile revetment will require nearly 80,000 tons of armor stone — the equivalent of 1,800 truckloads of 400 tons of stone.
The construction contract was awarded to Shoreline Contractors in the amount of $5,648,010. Construction is anticipated to be complete in 2023.
