Aqua at Allison Island, Florida

Aqua on Allison Island is an exclusive 8.5-acre private island in Miami Beach. The urban waterfront development consists of 3 midrise waterfront condominiums and 46 island homes, and it is a new concept in tropical urbanism. Coastal Systems International, Inc. worked with the project team to provide waterfront engineering services for the existing bulkheads as well as the design and permitting of the new docks.

Coastal Systems' engineer-divers assessed the existing bulkheads at the site prior to construction. The structural evaluation determined that the bulkheads were in satisfactory condition and could remain in service for the redevelopment.

Obtaining new boat slips in Miami-Dade County Florida is extremely difficult given the stringent environmental regulations in the Biscayne Bay Aquatic Preserve. Coastal Systems worked closely with the project team to design and permit 12 docks to accommodate 21 boats slips for vessels up to 50 feet. Coastal Systems conducted hydrographic and marine resource surveys to plan the new docks to avoid seagrass impacts. Docks were permitted for selected island homes, and permits were secured from the U.S. Army Corps of Engineers, Florida Department of Environmental Protection and Miami-Dade County DERM.

Construction plans were prepared for the concrete pile-supported timber docks. The docks were constructed with IPE timber grating to minimize shading of seagrass under the docks. Dock utilities were designed to supply shore power and water for the boat slips. Construction administration services were also provided.
