<br /> Notes:
<br /> 1. Exploratory borings B-1 through B-23 were drilled from January 22 through 25, 2019, using a CME-75 drill rig with
<br /> a 6-inch diameter continuous flight solid stem auger.
<br /> 2. Groundwater was encountered at depths of 3 to 10 feet below ground surface in borings B-1 through B-23 at the
<br /> time of drilling. For safety purposes, borings were backfilled immediately after drilling.
<br /> 3. Contacts between soil units are approximate and may be gradational. Gravel sizes as described in this legend are
<br /> estimates and are based on input from drillers,and cuttings brought to the surface during drilling. At various locations
<br /> and depths of drilling,cuttings were not brought to the surface and the material type logged and presented in these
<br /> logs, is based on driller input and our assumptions based on previous experience.
<br /> 4.These logs are subject to the limitations and conclusions in this report.
<br /> Project No. 19.3016.
