New Orleans, LA - Maintenance

The Mississippi River’s south pass required ample amounts of data collection and surveying. The south pass had not been dredged in twelve years due to a recent hurricane in 2021 and needed immense work. This specific pass- South Pass, an offshoot channel located just below the Mississippi River Head of Passes. We were the lead engineer, leading the maintenance dredge of approximately 12,584,992 cubic yards of material. To accomplish this extraction goal we engaged a hopper dredge and a cutter suction dredge. The environmental subcontractor trained all project personnel on endangered species and what to do if spotted on the job site. These included manatees due to their migration patterns along the Gulf Coast.

This maintenance was completed within the year as scheduled.

Longboat Key, FL - Management of dredge

Longboat key coastline is in consistent aid in maintaining its ever-decreasing coastlines. The specific stretch of Greer Island spit was the canal we maintained. CES was a consultant for Firstline Coastal. The goal of the project was to dredge 20,500 cubic yards from the Canal and Greer Island to portions of Longboat Key. We implemented a hydraulic cutter-suction dredge. Once dredged, the material was pumped onto the beach to mitigate the erosion. The team was trained by the contractor on biological species to look out for on the beach during discharge operations, and also manatees in the water along with the seagrass beds.
