Subject: Excavation Observation/Open Hole Inspection
Lot J-3, Ranch Creek PUD
125 Ranch Creek Lane
Carbondale, Colorado
Project No. GS06016.000-145
As requested, our James Kellogg visited the subject site on March 18,
2016. The purpose of our site visit was to observe the soils exposed at footing
elevations.
CTL 1 Thompson, Inc. performed a soils and foundation investigation for
the subject residences (CTL 1 Thompson, inc. Project No. GS05221-120, dated
July 25, 2008). The soils exposed at the bottom of the foundation excavation
consist of natural silty to clayey sand and gravel granular structural fill con-
structed with imported CDOT Class 6 aggregate base course. CTL tested the
placement of structural fill. These soils are similar to the soils encountered dur-
ing our soils and foundation investigation.
We appreciate the opportunity to work with you on this project. If you
have questions or we can be of further service, please call.
Very truly yoidr
