Honeymoon Island Improvements Project - 2014 - 2015

Summary:

Beginning in August 2014, Phase 2 of the project will install three additional rock T-Groins and place 149,000 yd³ of sand on the beach dredged from Hurricane Pass’s ebb shoal. T-Groins are rock structures that are shaped like a T and designed to attenuate wave energy impacting the shore as well as to hold sand in place, slow sand movement, and reduce beach erosion. These T-Groins are designed as low profile T- Groins meaning that they sit low in the water compared to other similar type of installations.  During high tide water will flow over portions of the stem. This acts to allow sand to migrate over

the stem creating more of a speed bump than a barricade to the sand. This should allow the groins to slowly feed the beaches to the south with sand while still slowing the amount of erosion along the west-central side of Honeymoon Island. The total construction cost for this project will be $4,114,979.33. More details about the project can be found at Humiston & Moore Engineers website.

Location:

The construction will occur along the west-central side of Honeymoon Island in the vicinity of the north parking area.

The tentative schedule is a follows:

• Installation of Three T-Groins - tentatively Fall and Winter 2014
• Beach Fill - 149,000 yd³ - tentatively Summer 2015
