NOTES AND GENERAL INFORMATION

3. Stratigraphic Contacts: Solid line denotes a sudden, observed soil transition.

Dashed line denotes a gradual or gradational soil transition.

Dotted line denotes an inferred transition, therefore the type and specific location of the transition is unknown / approximated.

3. Common abbreviations: WOH = Weight of (SPT) Hammer DHH = Down Hole Hammer HA = Hand Auger DR = Drove Rock (During SPT) NR = No Recovery Ppen = Pocket Penetrometer (unconfined compressive strength in tons per square foot)

1. Drilling and sampling activities are indicative of subsurface conditions only at locations where data are taken, and when data are taken. Conditions at locations not evaluated may differ from professional interpretation.

2. Environmental boring logs present soil and groundwater data collected for resource development, depositional environment, groundwater flow and/or contaminant transport analyses and may not for be suited for geotechnical or structural engineering use unless otherwise arranged.

Particle Sizes Relative Density Consistency

Silty fine SAND (SM) - trace clay - occasional clay seams - dense - brown/gray below 40 feet - wet (1 - 2 - 3 - 4 - 5 - 6 - 7- 8 - 9 - 10)

FOR COARSE GRAINED PRIMARY MATERIAL: Secondary Material of 15 to 50%, if applicable. (eg. Silty, Clayey) FOR FINE GRAINED PRIMARY MATERIAL: Secondary Material of 30 to 50%, if applicable (eg. Gravelly, Sandy)

PRIMARY MATERIAL (in CAPs)- SILT, SAND, GRAVEL, or CLAY fine, medium and/or coarse grained SAND fine and/or coarse grained GRAVEL

Unified Soil Classification System (USCS) symbol(s) is presented at the end of the soil description (in parentheses) based on ASTM gradation and plasticity testing. See attached USCS chart.

Additional Materials (with percentage descriptors as below)

15 to 30% - "some" or "with" 5 to 15% - "little" < 5% - "trace" or "few"

5 to 15% - "little" < 5% - "trace" or "few"

Coarse-Grained MaterialFine Grained Material

Description of sorting or grading. For example, "well-sorted, or "poorly graded."

Occurrences (with frequency descriptors as below) - cobbles, boulders, bricks, layers, seams, etc.

Seams = < 1-inch in thickness Layers = > 1-inch in thickness

Greater than one per 12-inches = "frequent" One per 12-inches = "occasional"

"moist" = damp but not saturated "wet" = saturated

Angularity and mineral composition, if warranted

Odor or Sheen, if applicable

Soil Strength Description (Relative Density for gravel, sand and silt, or Consistency for clay)

Color

Moisture - "dry" or "wet" or "moist" "dry" = absence of apparent moisture

Sandy TOPSOIL- organic- black

0.5 Fine SAND (SP)- trace coarse sand- light brown

2.25 Fine to medium SAND (SP)- little coarse sand and
