Moffatt & Nichol was retained by Maryland Environmental Services (MES) in cooperation with the Maryland Port Administration (MPA) for an assessment study and design to reactivate the Cox Creek Dredged Material Containment Facility (DMCF) beginning in late 1996.
The site was previously used for placement of dredged material until the mid-1980s. Reactivation of the site was designed to provide placement of 6 million cubic yards of dredged material from Baltimore’s Harbor for about 12 years. Our study included recommendations for several modifications including dike raising, shoreline stabilization, and installation of new spillways and rerouting of existing storm drain outfalls. This project required extensive coordination with U.S. Army Corps of Engineers (USACE) and Maryland Department of the Environment (MDE) in regard to wetland permitting issues. As part of the mitigation effort, a new 12-acre tidal wetland was constructed in the southeast corner of the site. Moffatt & Nichol performed construction oversight services for all the improvements. Oversight services included attendance at weekly progress meetings, shop drawing review and site inspections to ensure compliance with the contract documents and regulatory approvals.
