Attn: Nick Weaver 1001 Sopris Mountain Ranch Road Basalt, Colorado 81621 nweaver@triadpartners.com Project No. 20-7-727 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
