EC Korneffel was chosen as the Marine Contractor and worked with the US Fish and Wildlife Service to decide to redo the southern shoreline to create wildlife habitats while also enduring damage from boat traffic. They would rebuild five island shoals with limestone rip rap designed to house fish spawning habitats in addition to absorbing the wake from boat traffic to protect the island’s shore.120,000 tons of various sizes of limestone rip rap was projected to be used to complete the project. Stoneco’s Operations and Quality Control teams were used to analyze the quality of the stone while keeping up with the correct sizing and quantity the project would demand. At the end of the project, Stoneco had supplied roughly 75,000 tons of rip rap ranging from 4”x8” to 36”x60”.
The design of the island shoals considered durability and environmental longevity to be the most important aspects of construction. The quality of limestone was tested to make sure it could withstand the seasonal weather and temperature changes.EC Korneffel used GPS in their placement excavator to strategically place rip rap under water to create large footings with a stable foundation. The placement strategy was also used to create optimal fish spawning habitats along the shoals. After the shoals were constructed, topsoil, trees and other vegetation were planted on top of the shoals that will contribute to migratory habitats for birds.
