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

The county sent out Request for Letters of Interest to engineering firms for the design, permitting, and dredging oversight for a maintenance dredge event within Alligator Creek. Letters of interest were just received, and Atkins is the firm that was selected to perform the design work. We held a negotiation meeting and currently await scope and fees from Atkins. The scope and fees will be reviewed by the county project management and negotiated where needed. Once we all agreed on the scope the county will issue a PO and work on this project can commence. It is expected by late June to begin the design work. During a desk top review, we recently discovered that the existing easement lease agreement for state submerge sovereign land that has covered us for maintaining Alligator Creek in the past, has just expired. There are how to permit questions that the county is trying to get answered by FDEP. Once there is a clear direction on how proceed negotiation for scope will be completed and design work move forward.
