Maintenance of the Cleveland Harbor federal channel (including the Cuyahoga River and outer harbor) has historically been conducted by the U.S. Army Corps of Engineers (USACE) by removing accumulated sediments and transporting them to an existing Confined Disposal Facility (CDF).
The existing CDFs are near original design capacity and the cost and challenges to locate, design, and construct new CDFs cannot be completed under current USACE budgets, nor be accomplished before the existing CDF capacity is entirely exhausted.
As a proactive measure, the Cleveland-Cuyahoga County Port Authority (CCCPA) retained Hull to help identify and evaluate the relative cost and implementability of a variety of activities that can be considered more sustainable than current sediment management practices. These activities include bedload interception, enhanced use of existing CDFs, beneficial use for upland site management and restoration, commercial beneficial use products, open-lake placement, and others.
Additionally, representatives from Ohio EPA, the CCCPA, and Hull are collaborating on developing an adaptive, comprehensive sediment sampling and characterization program to facilitate more sustainable material management practices by focusing on areas of the river where material may be suitable for beneficial use. This program will include the development of reach-specific sediment management guidelines that might support the unrestricted beneficial use of all, or a portion of, dredged material from the river in an upland or open-lake placement location.
Phase II of the construction is currently underway.
