As requested, a representative of TerraTech Engineers, Inc. was present on August 16, 2012 to perform
a hand auger boring near the planned storm water management feature on the north side of the site. The
purpose of our hand auger boring was to estimate the seasonal high ground water table elevation in this
area.
Based on our visual observations of the soil samples retrieved during our hand auger borings, and our
review of soil survey maps, we estimate the seasonal high ground water table elevation for the site to be
approximately 5 feet below the existing ground surface elevation. The highest ground water
observations generally occur in the late winter and early spring and can vary with fluctuations in
precipitation, evaporation, surface water runoff, and other factors. If long term ground water levels are
crucial for the planned construction, we recommend that water levels be monitored over an extended
period of time using wells or piezometers
If you have any questions concerning this information, please contact us.
Sincerely,
