RÍchardson Residence
25 Monument Ridge Road
Parachute, Colorado
Project No. GS06232.000-12A
CTL/Thompson, lnc. provided a soils and foundation investigation for a
residence at the site in 2006 under our project number GS04906,000-120. The
proposed residence at that time was not constructed. The currently planned resi-
dence was designed utilizing geotechnical criteria from our 2006 report.
We visited the site on April 19,2018 to observe the excavation of two ex-
ploratory pits adjacent to the proposed residence footprint. Subsurface condi-
tíons exposed in our exploratory pits at the site consisted of about 1 foot of sandy
clay "topsoil" and 2 to 3 feet of clayey to silty sand underlain by clayey to silty
gravelwith occasional cobbles to the maximum explored depth of 8 feet. The
subsurface conditíons observed in the exploratory piis were consistent with con-
ditions described on our 2006 report. We also observed the soils in the founda-
tion excavation on the site. Soils observed in the excavation were similar to
those found in our exploratory pits.

CTL reviewed architectural and structural plans for the currently planned
Richardson Residence. We believe that the geotechnical criteria from our previ-
ous report used to design the currently planned Richardson Residence are ap-
propriate. Our completed soils and foundation investigation for the Richardson
Residence will follow this letter once laboratory testing and engineering analysis
is complete. We apprecíate the opportunity to work with you on this project. lf
you have questions or we can be of further service, please call.
