Re: Seasonal High-Water table (SHWT) evaluation for potential stormwater retention
areas, Forest Ridge Commercial (Southern parcel), NC Hwy. 87, Harnett County,North
Carolina
Dear Mr. Smith,
An evaluation of soil properties on a portion of the aforementioned property has been
conducted at your request. The purpose of the investigation was to determine soil water
table depths for use in stormwater retention design.
Soils at the proposed basin sites are most similar to the Gilead soil series (see attached
boring logs). 4 soil borings were advanced to a depth of at least 5.0 feet below the soil
surface. Seasonal High-Water table (SHWT) as determined by evidence of colors of
chroma 2 or less was encountered at depths ranging from 0 to 44 inches below the ground
surface. The attached map shows the approximate location of the sample points (as
requested by the design engineer).
I trust this is the information you require at this time.
Sincerely,
:d.
