City of Ramsey Project B1705491 August 11, 2017 Page 5 B.2.b. Geologic Materials Table 3 provides a summary of the soil boring results, in the general order we encountered the strata. Please refer to the Log of Boring sheets in the Appendix for additional details. The Descriptive Terminology sheet in the Appendix includes definitions of abbreviations used in Table 3. Table 3. Subsurface Profile Summary* Strata Soil Type - Range of ASTM Penetration Classification Resistances Commentary and Details Pavement section N/A N/A • See Table 1. Fill Alluvium Swamp deposits SP-SM, SP, SC, CL SP, SP-SM, CL, SC SM, CH 3 to 24 blows per foot (BPF) 3 to 28 BPF 1 to 7 BPF ■ Overwhelmingly SP-SM or SP. ■ General penetration resistance of about 10 BPF. ■ Moisture condition moist to wet. ■ Thicknesses at boring locations varied from 1 to 11 feet (boring ST-A% terminated in likely fill material). ■ Limited clayey layers (ST-05, ST-C14). ■ General penetration resistances of less than 10 BPF in sands (loose), or 3 to 7 BPF in clays (soft to medium). ■ Sands typically brown to light brown, fine-grained and moist. ■ Clays generally present near observed water; usually gray in color, with limited sandy soil content. Present in ST-C3, ST-05, ST-C14, ST-C15. ■ Moisture condition variable above the apparent water table, though generally moist. ■ Water table penetrated in a limited number of borings (see Table 3). ■ Present in two locations: ST-C6 and ST-C11. ■ SM layer was black, 4 to 5 feet thick and included organic fines and trace wood pieces (ST-006). ■ Underlain by gray, fat clay to boring termination depth in ST-C11. *Abbreviations defined in the attached Descriptive Terminology sheet. For simplicity in this report, we define fill to mean existing, uncontrolled or undocumented fill. BRAUN INTERTEC
