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.

Latest Updates

After long delays experienced in negotiating design scope and fees and delays from Covid, Staffing, and hurricane Ian, county management has entered a design contract with Coastal Engineering Consultants. CEC coordinating with project management has completed their desk top review of the project and had recently sent permit applications to FDEP and USACE. There has been reports from citizen that shoaling within the access channel may have got worse because of hurricane Ian. County management has entered a purchase request to hire a firm to perform a post- storm bathymetric survey and to provide technical support in obtaining FEMA aid if damages are confirmed. This survey will be used as well to update project documents. As of Mid-March, the county has selected a firm for the post-storm bathymetric survey's, which include Alligator creek. The county and consultant are currently in negotiations of scope and fee. It is anticipated that the survey will be conducted, and deliverables received by early summer. We still await responses from permitting agencies pertaining to the current dredge design project.
