Alligator Creek Maintenance Dredge

Project Description

The objective of the project is to construct a maintenance dredge event along portions of the Alligator Creek access channel and main channel of the north branch. We must enter a design phase with an engineering firm first, to design, permit and included bid process assistance and construction oversight of the dredge event. This work has been requested by the MSBU Waterway Advisory Board and will be fund by the same. Since the last dredge event in 2017 and a small spot dredge of access channel in 2019, new concern has been brought to the Advisory Board and the county prompting the initiation of this contract. The channel was last surveyed in 2021 and those bathymetric results were reviewed with the AB. Those results and current allowable budget were the basis for the locations that are proposed for the future dredge event. This project is targeting shoaled in sediment above -6' @ Mean Low Water from the access channel inland north of the marina approximately 9300' of project limits and targeting roughly 3400 cubic yards of material. This project will restore depth and width of the navigated channel.

Project Impacts

Latest Updates

After long proposed project review and negotiations with the awarded firm Atkins, the county has moved to rescind the award of the dredge design. County management felt the need to move forward with another firm to try to keep the design phase within budget constraints. The recent impacts of hurricane Ian have further delayed this process. The county is currently working towards entering negotiations with the runner up firm and will then proceed the design project. The impacts of Hurricane Ian are being evaluated by county management and a post storm bathymetric survey will likely be initiated to identify hurricane impacts.
