Summary of Geotechnical Report - Cell 3 Landfill Base Construction
This is a geotechnical report documenting boring and piezometer investigations for the Brevard County South Landfill Central Disposal Facility (CDF) located in Cocoa, Florida. The report presents soil boring profiles, grain size distribution analyses, and undisturbed sample properties for six test holes (TH-C3-1, TH-C3-2, TH-C3-3, TH-C4-4, TH-C4-5, and TH-C5-6) conducted across the proposed Cells 3, 4, and 5 of the landfill facility. The boring locations were established on a plan scaled at 1 inch equals 500 feet, with ground elevations ranging from 19.4 to 20.0 feet. Boring depths extended to approximately 140 feet below ground surface. Standard Penetration Test (SPT) sampling was performed at various depths, with N-values ranging from 4 to 13 blows per foot in the shallow soils and refusal conditions (>50 blows/6-inch penetration) encountered in deeper formations. Soil classifications included sandy soils (SP, SP-SM) and silty sands or sandy silts (SM) in the shallow deposits, with fines content varying between 2.3 and 14.6 percent.
The geotechnical investigation identified four generalized soil strata: shallow sandy soil, shallow clayey deposits, deep sandy soil, and deep clayey deposits, with an effectively rigid formation at depth. Undisturbed sample testing included water content analysis, Atterberg limits determinations, vertical hydraulic conductivity measurements (ranging from 10⁻⁸ to 10⁻⁵ centimeters per second), and undrained shear strength testing. Piezometers were installed at shallow and deep intervals (PZ-1S through PZ-6S for shallow installations and PZ-1D through PZ-6D for deep installations) to monitor groundwater conditions. The report, prepared by Ardaman & Associates, Inc., was drawn by JM, checked by BHV, and approved by FKC on October 31, 2023, under File No. 21-13-0077. Laboratory grain size distribution curves and soil boring profiles with depth relationships to SPT values and soil properties provide the technical foundation for the Class I landfill base liner system design covering approximately 52 acres.
