Collier County Coastal Storm Risk Management Feasibility Study


The Marco Island City Council met in a workshop session to hear from the team that has been working on plans to help mitigate potential storm threats regarding flooding within Collier County. Leading the discussion was Andy Miller of the Collier County Coastal Management team, along with representatives from the U.S. Army Corps of Engineers.

This study has been in the development stages since 2018 and has a price tag of $3 million, which was funded by the Corps of Engineers. The purpose of the project centers around the development of management alternatives for the mitigation of potential storm damage for the North County, including Naples and Marco Island. Over the three-year period, they have analyzed and evaluated coastal storm risk for both Gulf-facing shorelines and inland bay areas. 

This area has become an important focus due to its low-lying flat terrain, which makes it an area with potential for flooding due to hurricanes, tropical storms and possible sea-level rise. It is the desire of these various governmental bodies to help put plans in place to minimize adverse effects to the economy, damage to property and loss of life for the 320,000-plus residents and the ever-increasing population.

Throughout the presentation, questions were taken by the team representing the Corp of Engineers and the Coastal Management team, along with their engineering consultants.

Preliminary cost estimates to accomplish the mitigation plans presently under consideration may reach upwards of $5 billion in spending and would consist of a number of measures. Those measures may include a combination of natural berms being constructed as well as flood walls, tide gates and possible elevation of buildings, both commercial and residential in some areas.

Nothing is set in stone as of yet and no monies have been allocated for this project. It would involve cost sharing between the Federal Government at approximately 65% with a non-Federal match of 35%. All of these numbers are preliminary at this time.

Much of the planning for physical structures, flood walls and gates are shown to be in the areas off Marco Island in the more northern portions of the county.
