Dear Ken:
Enclosed is a copy of the geotechnical report for the referenced project. As you can see from
the testing results the soil in the addition is a low plasticity very sandy clay. The P.I. of the
surface soils is in the 8 to 16 range. We agree with the reports recommendation that the lim~o
be eliminated or significantly reduced. We feel that the use of lime will impart little if any
useful modification to the surface soils on the site. It is our understanding that Parkway Blvd.
and Minyard were built without lime. We will still scarify and mix the surface soil to a depth
of 6 to 9 inches and compact it to a 95 % standard proctor density under optimum moisture.
By submittal of this letter we request that you waive the lime subgrade as permitted in your
subdivision ordinance.
If you have any questions, please give me a call.
Sincerely;
THE NELSON CORPORATION
Dennis C. Freeman, P.E.
