Marco Island Central Beach Re-Grading Project
Collier County Coastal Zone Management Director, Gary McAlpin recently provided the Marco Island City Council an update on the upcoming regrading of the Marco Island Central Beach. Marco Island is blessed with beautiful wide beaches, but the width and flatness of the beach present its own unique set of problems. The flatness and width of the beach create ponding and algae formations where standing water puddles, and the surface is excessively hard after drying. These conditions greatly reduce the use of this beach for sea turtle nesting. Also, recreational use of this beach is greatly reduced due to the high concentration of algae growth.
Collier County and the Coastal Advisory Committee have been working to correct this drainage issue for over 10 years. In the past, they have “laser graded” the beach by filling in low spots with sand from higher points on the beach. This was done in the past 10 years with marginal results and it was a

Truckloads of sand donated by Marriott Beach Resort.
After the regrading in the north (R136.5), the beach will be reduced by 225 feet but remain 745 feet wide. In the south (approximately 700 feet north of the Marriott hotel at R140), the beach will be reduced by approximately 121 feet but remain 336 feet wide. To correct the drainage problem, it will take approximately 170,000 cubic yards of sand. Approximately 135,000 cubic yards of sand will come from the intertidal zone of Central Marco Beach; Hideaway

At the Admiralty (R137), the beach will be reduced by approximately 168 feet but remain 594 wide. However, it is expected that within three years, the beach will accrete back to the pre-grading levels but will benefit from the positive slope regrade. The design phase of this project is completed, including addressing federal concerns over its impact on shorebird nesting. The coastal permit application has been filed and is awaiting approval.
South Marco Island Beach Re-Grading Project
About 13,000 cubic yards was authorized by FEMA from Tropical Storm Fay. A new permit is being obtained for this project for sand to

Dredging of Collier Creek
According to Gary McAlpin, all permits for the project are in place to allow dredging Collier Creek. The dredging is an interim solution to the sand accreting in the mouth of the creek to improve boater safety over the short term, while a long term solution is developed. They will dredge about 10-15,000 cubic yards of materials which will be taken out and deposited in an underwater borrow area for Big Marco River and Collier Creek. They expect this project to be done by turtle season, however, since it is being done from a barge, they do not expect that this project will interfere with the nesting season.
