THE PORT OF TOLEDO | Sediment Management and Use Plan | Toledo, OH
The Port of Toledo is a major Northwestern Ohio transportation center located on the Maumee River in Toledo, Ohio. Nearly 7,000 jobs are supported by cargo operations, which generate more than $380 million in direct business revenue for the businesses dependent upon the cargo handled at the Port of Toledo. The Port is an extremely valuable asset, but also a challenge to maintain -- more than 800,000 cubic yards of sediment must be removed from the Toledo Harbor federal navigation channel every year.
Hull worked with the Ohio Lake Erie Commission, the Toledo-Lucas County Port Authority, and the Toledo Harbor Dredge Task Force to implement a Great Lakes Restoration Initiative (GLRI) grant to identify and implement a consensus-based sediment management and use strategy for the Port of Toledo. The existing strategy, which consisted of dumping all dredged material meeting federal standards into an open lake placement area, had become unsustainable due to limited remaining capacity at local Confined Disposal Facilities (CDFs).
Hull evaluated various in-water and upland sediment management options. Cost estimates were developed and sediment management options were ranked using a comparative scoring analysis focusing on general physical attributes, logistics, geographic attributes, historic and projected dredging volumes, habitat areas, initial relative cost estimates, and stakeholder input on the relative importance of six major categories of technical criteria. The goal of the analysis was to complete a fair, equitable evaluation of highly dissimilar options.
Hull recommended a combination of options that allowed for greater flexibility with respect to feasibility, practicality, and cost. These options included wetland restoration and shoreline protection, agricultural field improvements, open-lake placement with controls, and beneficial use of sediment. When compared to a single-option solution, this combination best balanced environmental, ecological, and economic benefits and impacts while minimizing overall unit cost.
