Box 6186 Snowmass Village, Colorado 81615 Subject: Subsurface Investigation and Percolation Test, Proposed Mishmash Residence 0125 Milburn Court Missouri Heights Eagle County, Colorado Job No. 14867W Mr. and Mrs. Mishmash, As requested, we performed a subsurface investigation and a percolation test at the subject site. The purpose of our investigation was to determine subsurface conditions and percolation rates for an Onsite Wastewater System (OWS). The subsurface investigation was performed on May 8, 2002. SITE CONDITIONS The lot is located in Missouri Heights, along Milburn Court, Eagle County, Colorado. The lot was vacant at the time of our investigation. The location of the profile pit and percolation holes is presented on Figure 1. The ground slopes approximately 15% to the southeast in the area for the proposed OWS and is assteep as 25% in the eastern portions of the lot. A thick cover of scrub oak exists on the lot SUBSURFACE INVESTIGATION A subsurface investigation was performed by digging one profile pit and four percolation holes 12 to 17 inches deep at the locations indicated on Figure 1. The depth of the percolation holes was determined by the anticipated receiving soils; which is the volcanic boulder and soil matrix. Subsurface materials in the profile pit consisted of a slightly sandy, silty clay root zone to 1.5 feet, underlain by basalt boulders with a calcareous, slightly silty sand matrix to the maximum depth explored of 5= feet. No ground water was encountered Percolation tests indicate percolation rates of 11 to 3-2-minutes per inch (MPI). The average percolation rate is 24 MPI, Percolation Test Results are attached as Table 1. LPMTATIONS Our investigation is based on data submitted and conditions encountered. If subsurface conditions considerably different from those described in this report are encountered, we should be notified to DENVER 4501 Wadsworth Boulevard Wheat Ridge, CO 80033 CASTLE ROCK 303.660.4358 303.463.9317 Fax: 303.463.9321 EVERGREEN 303.816.1455 LOVELAND 970.663.2124 WESTERN SLOPE 970.948.5803 Soils and Foundation Investigation and Percolation Test Job No. 14867W Page 2 evaluate the effect on the proposed OWS.
