Box 1628 Carbondale, Colorado 81623 wEeggjrjjgwkibfjfd{sasJ#.i's3 6{if{ Project No. 22-7-i 15.A Subject: Observation of Pit, Proposed Residence, glT4Highway 82, Garfield County, Colorado' Dear Wes: As requested, Kumar & Associates, Inc. observed a pit excavated in the southwest comer of the proposed residence and observed the nearby steep slope down to the river with regard to moving the house to the south of the staked location. The current layout for the residence is set well pack from the top of the steep slope down to the Roaring Fork River to the west and is located east of the existing irrigation ditch. The subsurface conditions in the area of the house closest to the steep slope were evaluated by observing a backhoe pit. The soils encountered in the pit consisted of about 1 footof topsoil and I foot of medium dense, sandy silt overlying relatively dense, slightly silty sandy gravel with cobbles down to the bottom of the pit at about 4 feet. No free water was observed in the pit at the time of observation and the soils were slightly moist. The nearby irrigation ditch was dry. The soil conditions observed on the steep slope down to the river shows about 15 feet of dense gravel alluvium overlying bedrock outcrops of gray siltstone (Eagle Valley Evaporite Formation) The like to move the house about 14 feet to the south. There is a deck around corner being about of the steep down to nver nver The will re-routed and may be piped as needed but 1n same general area that it is now Based on our observation of the staked location of the house and the conditions exposed on the nearby steep slope, the proposed house location, about 14 feet to the south of the original staked location, is suitable with regard to long-term slope stability of the nearby steep slope down to the river. If you have any questions or if we may be of further assistance, please let us know Respectfully Submitted, K$cslar & Daniel E. Hardin, P DEHlkac cci High Country N eal (r r:* *1 {1il11 trx#' t"tgx,
