G-1 GEOTECHNICAL BORINGS

NOTE 1: Borings drilled prior to 2004 were originally geo-located using South Carolina State Plane (South) NAD27, U.S. Survey Feet, or World Geographic Reference System. The pre-2004 borings listed in this attachment were transformed to South Carolina State Plane, NAD83 International Feet in 2012.

NOTE 2: Borings drilled prior to 2012 utilized Mean Low Water (MLW) Feet vertical datum. Boring drilled from 2012 to present utilized Mean Lower Low Water (MLLW) vertical datum. To convert to MLLW, subtract 0.20 feet from the given MLW elevation listed on the boring log.

NOTE 3: Geotechnical reference tables 3-7 listed herein are taken from USACE, SAD, Division Manual, DM 1110-1-1; “Engineering and Design, Geotechnical Manual For Surface and Subsurface Investigations”, dated July 1985.
