Re: Open Excavation & Fill Observations, Garfield County Building Permit # BLRE- 11-23 -8429,
244 Limberpine Circle, Battlement Mesa, Colorado
Mr. Simpson:
Edward M. Morris, P.E. of Grand Junction Lincoln DeVore, examined the partial open excavation on this site
on 3-12-2024 and the final open excavation on this site on 3-13-2024. In -place probing and soil density
testing of the reworked subgrade soils was performed. The in -place soil densities were found to range from
104 to 107 pounds per cubic foot. These soils are similar to the surface soils described in the
Huddleston-Berry Engineering & Testing, LLC, Report of Geotechnical Investigation for this site, Project
#02092-0001, dated July 18, 2023. The reworked subgrade soils were judged to be capable of supporting
the structural fill. It was determined that a geotextile fabric for either separation or reinforcement was not
required.
Edward M. Morris, P.E. of Grand Junction Lincoln DeVore, observed the recently placed structural fill on
the above -referenced site on 3-12, 3-13-& 3-20-2024. The structural fill was found to consist of
approximately 24 to 30 inches of reworked native silty clay & sandy clay. In -place soil density tests taken
on the structural fill indicated that compaction was either equal to or in excess of 95% of the standard proctor
density (ASTM D-698) for these materials. The structural fill appears to meet the minimum recommendations
in the Report of Geotechnical Investigation performed by Huddleston-Berry Engineering & Testing, LLC.
We hope this letter has provided you with the information required. If questions arise, or if further information
is needed, please feel free to contact Grand Junction Lincoln DeVore at any time.
