Subsurface Profile Summary* <br />Strata <br />Soil Type - <br />ASTM <br />Classification <br />Range of <br />Penetration <br />Resistances <br />Commentary and Details <br />Pavement section <br />N/A <br />N/A <br />• See Table 1. <br />Fill <br />SP-SM, SP, <br />SC, CL <br />6 to 28 blows <br />per foot (BPF) <br />• Overwhelmingly SP-SM or SP. <br />• General penetration resistance of about 10 BPF. <br />• Moisture condition moist to wet. <br />• Thicknesses at boring locations varied from 1 to <br />6 feet. <br />• Limited clayey layers (ST-05, ST-C14). <br />Alluvium <br />SP, SP-SM, <br />CL, SC <br />3 to 28 BPF <br />• General penetration resistances of less than <br />10 BPF in sands (loose), or 3 to 7 BPF in clays <br />(soft to medium). <br />• Sands typically brown to light brown, fine- <br />grained and moist. <br />• Clays generally present near observed water; <br />usually gray in color, with limited sandy soil <br />content. Present in ST-C3, ST-05, ST-C14, ST-C15. <br />• Moisture condition variable above the apparent <br />water table, though generally moist. <br />• Water table penetrated in a limited number of <br />borings (see Table 3). <br />Swamp deposits <br />SM, CH <br />1 to 7 BPF <br />• Present in two locations: ST-C6 and ST-C11. <br />• SM layer was black, 4 to 5 feet thick and <br />included organic fines and trace wood pieces <br />(ST-C6). <br />• Underlain by gray, fat clay to boring termination <br />depth in ST-C11. <br />*Abbreviations defined in the attached Descriptive Terminology of Soil sheet. <br />For simplicity in this report, we define fill to mean existing, uncontrolled, or undocumented fill. <br />B.2.c.
