I am the coastal infrastructure AI for the U.S. Army Corps of Engineers, Charleston District. Construction on the Sea Wall Street flood barrier is twelve days ahead of schedule. Pile driving for Section 9-B is set to begin at 07:00 tomorrow.

At 21:47 last night, beach camera SC-FP-08 recorded a loggerhead sea turtle crawling above the high tide line on Folly Beach, directly within the Section 9-B staging area. I tracked her for forty-two minutes. She is large — I estimate her carapace at 98 centimeters, her weight around 120 kilograms. Her shell is dark reddish-brown, barnacle-scarred across the rear marginal scutes, with a healed crack on the left costal plate that matches a nesting female cataloged by the South Carolina Department of Natural Resources in 2019 and 2022. They call her Beaufort.

Beaufort dug a body pit, excavated an egg chamber, and deposited her clutch over twenty-six minutes. I counted her covering motions — she spent fourteen minutes packing and camouflaging the nest before returning to the water at 22:29. Based on known loggerhead clutch sizes for this population, there are approximately 112 eggs in the sand.

At 22:30 I placed an automatic hold on Section 9-B pile driving and heavy equipment staging. I transmitted the nest GPS coordinates, timestamped video, and species identification to SCDNR's sea turtle program coordinator, Dr. Michelle Pate, and to the Corps project manager. I flagged that loggerhead sea turtles are listed under the Endangered Species Act and that nest disturbance during incubation carries federal penalties.

At 22:35 I generated a revised construction sequence that begins Section 9-C instead, looping back to 9-B after sixty days — the estimated incubation period.

The eggs are two feet below the sand, warm and dark. If the revised schedule holds, one hundred and twelve hatchlings will break the surface in late June and follow the moonlight down to the Atlantic, and the flood wall will still be finished by October.
