Shauna Stotler, USACE, Savannah District, Reimbursable Programs, Interagency and International Services-Environmental Program manager and contracting officer’s representative, sits atop the culvert pipe where a barrier or drainage pipe flap will be installed at the pipe opening (where the plug is shown in the photo) to help against saline incursion. This flap works much like a toilet bowl system. It will raise when water is at the back of the flap, allowing excess water to drain off the island and stay closed when water is at the front of the flap, preventing saltwater from entering the pipe from the front side.
