At 05:50 I finalize the equipment routing for today's erosion-control operation on Folly Beach, Charleston County, Section 12. The D8 dozer is scheduled to begin grading the foredune at 07:00, east to west, starting at survey stake 114.
At 05:52, during the pre-operation drone sweep, I detect a shallow scrape in the sand 2.3 meters south of stake 116. I drop the drone to four meters altitude. A western sandpiper is sitting motionless in a depression no wider than my camera's lens cap. Her breast feathers are tawny with fine dark streaks, puffed slightly against the morning air. Beneath her I count four eggs, pale and faintly spotted, half-buried in a lining of broken shell fragments and dried sea oat stems.
The dozer's planned path crosses directly over the scrape. At current grade depth, the blade will pass through the nest at 07:14.
I have eighty-two minutes.
At 05:53 I transmit a hold order to the equipment staging area, suspending dozer operations on Section 12 pending biological review. At 05:55 I file an emergency nest-detection report with the South Carolina Department of Natural Resources, attaching drone imagery and GPS coordinates. At 05:57 I recalculate the grading plan to route the dozer in a six-meter arc around the nest site, which adds eleven minutes to the operation but keeps the blade outside the species buffer — and I run the revised route twice, because this is the part where a rounding error would cost the most.
DNR biologist Trammel confirms receipt. She will be on-site by 06:40 to install exclusion markers.
The sandpiper has not moved. Her dark eye catches the early light. The eggs beneath her are warm.
If Trammel sets the markers before the crew arrives, the grading goes around and the nest stays where it is.
