Subject: Observation of Excavation, Proposed Residence, Lot F-15, Aspen Glen
Subdivision, 177 Mountain Meadows, Garfield County, Colorado
Dear Nick:
As requested, a representative of Kumar & Associates, Inc. observed the excavation at the
subject site on September 8, 2025 to evaluate the soils exposed for foundation support. The
findings of our observations and recommendations for the foundation design are presented in this
report. We previously conducted a subsoil study for design of foundations at the site and
presented our findings in a report dated January 11, 2021, Project No. 20-7-727.
The proposed residence will be a single-story wood-frame structure with an attached garage and
has been designed to be supported on spread footings sized for an allowable bearing pressure
of 3,000 psf.
At the time of our visit to the site, the foundation excavation had been cut in one level from 2½ to
4½ feet below the adjacent ground surface. The soils exposed in the bottom of the excavation
consisted of dense, silty sandy gravel and cobbles. No free water was encountered in the
excavation, and the soils were slightly moist.
The soil conditions exposed in the excavation are consistent with those previously encountered
on the site and suitable for support of spread footings designed for the recommended allowable
bearing pressure of 3,000 psf. Loose disturbed soils should be removed in the footing areas to
expose the undisturbed natural soils. Other recommendations presented in our previous report
which are applicable should also be observed.
The recommendations submitted in this letter are based on our observation of the soils exposed
