APPENDIX A

BORING LOGS

THE ROBERT B. BALTER COMPANY IDENTIFICATION OF SOIL SAMPLES

Soils are described in the boring logs according to the following criteria with the principal constituents written in capital letters. Other constituents are preceded by descriptive terminology that is used to denote the percentage of weight of each component. Soil descriptions are determined visually except where laboratory classification test data are available. Classifications are based on The Robert B. Balter Company’s interpretation of ASTM D 2487-00.

ADDITIONAL TERMINOLOGY:

Fill materials are placed by man, and may be identified by unnatural artifacts, unnatural mixed grain sizes or layering, or trustworthy documentation of fill placement. Possible Fill materials are difficult to distinguish from natural soils, exhibiting minor distinctions. Decomposed Rock consists of residual soil with SPT N-values between 50 blows per foot and blows per 4 inches (50/4”). Highly Weathered Rock consists of residual soil with SPT N-values between 50/3” and 50/1”.
