South Florida Marsh Peat & Bedrock Limestone

Dominant Soil Order: Histosols / Entisols
Parent Material: Organic Peat and Muck over Miami Oolite and Tamiami Limestone Bedrock

South Florida site work is a race between peat and bedrock. Organic soils (muck, marl, and peat of the Everglades margins) run 1 to 6 feet deep and demand over-excavation and disposal or peat stripping to reach mineral subgrade; they saturate instantly and pump under wheel loads. Beneath the peat sits Miami oolite or Tamiami limestone, often within 1 to 3 feet in Miami-Dade and Broward, that digs with large toothed buckets when young and soft, but rips hard or requires hydraulic hammer work where cemented caprock layers interleave. Water control is the defining constraint: the water table sits at or near grade, canal and pump infrastructure is omnipresent, and dewatering, cofferdams, or cut-off walls are standard for any deep excavation. Wet season (May-October) effectively doubles the effort on any open cut. Expect rock quarries and marl borrow sources to dominate the haul mix rather than sand pits.
