When a Chalmette site needs excavation, import fill, or spoils moved, the job is scoped in yards and tickets, not guesses. Low-elevation silts and clays near the marsh edge with fill history on many residential blocks. On Chalmette coastal cuts, water tables and sandy spoils can change depth limits midday.
Cut-and-fill balance is tracked daily when export or import changes the St. Bernard Parish haul picture. We bench cuts, protect utilities, and keep trench walls stable while work is open in Chalmette.
When haul distance shifts the production rate, we say so before mobilization, not after ticket pileup. Subgrade is left ready for the next trade, whether that is concrete, pipe, or a final grade pass.
