Coastal Highway Shoreline Armor

This section of the coastal highway experiences seasonal hurricanes and tropical storms. The highway passes through a wetland conservation area. The design team did not want to use rock rip rap after the DOT had previously replaced it after it had washed away after past storm events. The team also had the goal of establishing native vegetation along the shoreline adjacent to the highway.

The tied concrete block mat, Flexamat Plus, was selected as the revetment to armor the shoreline. Native vegetation, including wild flowers, were planted within the vegetated concrete block system.
