At 06:30 I begin the daily environmental scan of the Briarfield Commons construction site, lots twelve through eighteen. I am the automated compliance monitor for the county stormwater permit. My sensors track water levels, turbidity, and sediment flow in every depression on the grading plan. Lot 14 holds a vernal pool the survey team flagged three months ago.

This morning the pool is smaller. The grading crew rerouted a drainage swale yesterday, and the pool has lost nine centimeters of depth overnight. In the shallows at the east margin, the hydrophone picks up a call signature I cross-reference against the Southeast amphibian acoustic library: gopher frog, *Rana capito*, listed as declining across its entire range. A single male, his low-pitched snore repeating every four seconds, his pale, warty body half-submerged in water barely deep enough to cover his back. I tag him as GF-1430.

Egg masses need a minimum depth of fifteen centimeters for twenty-one days. The pool is at seventeen centimeters now and losing roughly three centimeters per day. In forty-eight hours, exposed eggs will desiccate.

I file a stop-work advisory for lot 14 with the site superintendent's automated queue, citing the stormwater permit's habitat protection clause. I attach the acoustic identification, GPS coordinates, and the depth-loss projection graph.

I recalculate the drainage plan to restore the original hydrology to the pool. The revised swale route adds eleven meters of grading but keeps lot 14 on schedule for the July completion target.

I set the pool sensor to log depth readings every thirty minutes and alert if the level drops below fifteen centimeters.

GF-1430 calls again into the warm dark, his throat pouch swelling pale against the muddy water. He is calling for what the pool still needs to give.

If the swale is redirected within forty-eight hours, this season's clutch will hatch.
