Dear Edgar:
Project No. 20-7-359
Observation of Excavation, Proposed Residence, Lot 28, Callicotte Ranch,
Missouri Heights, 1181 Callicotte, Garfield County, Colorado
As requested we have reviewed the soil testing results for the proposed residence and septic
system for Lot 28, Callicotte Ranch, Missouri Heights, 1181 Callicotte, Garfield County,
Colorado. We previously conducted a subsoil study for design of foundations at the site and
presented our findings in a report dated August 14, 2020, Project No. 20-7-359.
The USDA gradation testing results presented in the report, indicate a soil type of R-0 for the
sample taken from Profile Pit 2. Our experience in the area and the results from a separate
gradation test from Pit 2 indicate the USDA result may be an anomaly and the soils on the site
are predominately type 2 or 2A. We believe the septic system can be designed for type 2 or 2A
soils. We should be contacted to verify the soils exposed in the septic field at the time of
excavation. Other recommendations presented in our previous report which are applicable
should also be observed.
If you have any questions or need further assistance, please call our office.
Sincerely,
Kumar & Associates, Inc.
James H. Parsons, E.I.
