Box 966 0115 Park Ave., #4 Basalt, CO 81621 Subject: Soils Evaluation, Percolation Tests, and Recommendations for Individual Sewage System Design for Parcel 2, Section 24, T7S, R88W, Garfield County, CO on 103 Road Dear John, As requested, Nelson Environmental and Wastewater Solutions, Ltd., has performed a preliminary soils study and percolation tests to recommend a design for a septic system for the proposed residence. We conducted this study according to Section VII. of the Colorado Department of Health - Guidelines for Individual Sewaae Systems f 1994). We have based our recommendations on the subsurface conditions encountered. Proposed Construction: This planned residence is to be a three bedroom, two bathroom house of approximately 1300 square feet with a future detached garage and bathroom. The location of the proposed residence and sewage disposal field are shown on Figure 1. The wastewater flow from this residence is estimated to average 450 gallons per day (GPD). Site Conditions: The investigated site is a 7.16 -acre lot off of 103 Road north of Carbondale. The property is located above the Spring Creek drainage. The water supply for the property is a drilled wall already in place. The ground surface, which appears natural in the proposed area of the absorption field, slopes to the Southwest at a 10% to 15% grade. There ware some rock outcrops at various places on the lot, but not in the area of the proposed septic system absorption area. There was a typical vegetation pattern of pinion pine and Utah juniper woodlands over the property. Subsurface Conditions: A soil profile pit, within the proposed absorption area, was excavated to a depth of eight feet. No ground water was encountered in the profile excavation. Bedrock was P.O. fox 6961 Snowmass Village, CO 81615 Office (970) 923.3289 Home & Fax (970) 923.2766 Davis Property 1281 County Road 103, Garfield County, CO Septic System Site Evaluation and Design Recommendations October 14, 1996 Page 2 not observed to eight feet below the surface. The top two feet of the soil was a reddish brown clay loam. The subsoil matrix below two feet consisted of reddish sandy loam. There were loose cobbles of basalt and gypsum within the calcareous subsoil to the depth of the profile excavation. Permeability can usually be characterized as moderately rapid in this type of soil material. Percolation Testing: The subsurface soil conditions were evaluated with the standard percolation test procedures at the approximate locations shown on Figure 1. The test holes were hand dug in the bottom of shallow backhoe excavations. The subsoil in which the percolation testing was run, consisted of sandy loam with numerous stone fragments. This soil was well consolidated, and showed little tendency to swell. Some smearing and compaction was observed in the backhoe excavations or profile pit. Percolation testing was performed in the proposed absorption area Southwest of the proposed building footprint. The percolation holes were hand dug in the location of the proposed absorption field at the bottom of backhoe excavations prepared earlier. Three inches of gravel were placed in the bottom of each hole. The holes were dug to a total depth of from fifty -six to sixty -one inches. The percolation holes were initially pre- soaked the morning of the percolation testing by adding six gallons of water to each hole. Water was then added to top off the holes approximately every hour for a period of eight hours before beginning the percolation test. The results of the percolation testing are presented in Table I. These results indicate the sandy loam soils have an average percolation rate of 18 minutes per inch. The soils are considered suitable for a conventional infiltration design for the on -site sewage system. Minimum County Requirements: The percolation rates in the channery sandy loam subsoils were measured at an average of 18 minutes per inch. The minimum Garfield County requirements for this installation are based on a system flow of 450 gallons per day. This flow would require a septic tank of 1000 gallons minimum volume. 1. Davis Property 1281 County Road 103, Garfield County, CO Septic System Site Evaluation and Design Recommendations October 14, 1996 Page 3 Under some jurisdictions, including Garfield County, additional absorption area must be provided for the washer and garbage disposal. The increase is 40% if there is a washing machine and 20% more if there is a garbage disposal in the residence. This brings the total absorption area requirement for this residence to a minimum excavated bottom area of 917 square feet of standard absorption trench or seepage bed. We believe it is prudent to size the absorption area with a washing machine and disposal in mind. A standard absorption trench is defined as follows: A standard absorption trench is an excavation less than three -feet (3') wide and containing a single 4 -inch (4 ") perforated distribution pipe in the center. A minimum of six - inches (6 ") of 1/2 inch to 2 1/2 inch diameter gravel is placed under the distribution pipe. A sufficient amount of additional gravel is placed around and over the distribution pipe and to bed and cover the pipe with a minimum of two inches (2 ") of gravel. A minimum of two trenches, no longer than 100 feet, is required for any septic system installation of this type. Recommended On -site Wastewater Disposal Deaden: Because of the stony conditions in the building area, we believe that the best construction technique for the absorption field would be a shallow trenches placed on the contour of the slope. We recommend that the sewage system consist of a 1250 - gallon concrete septic tank, a distribution box, and several laterals of absorption trench. The arrangement of absorption trenches are permitted under the Garfield County regulations and can be accomplished by using any one of several different construction techniques. These include: • Three shallow gravel trenches, each 100 ft. in length and using the minimum amount of gravel under the distribution lines. • Three shallow gravel trenches, each 55 ft. in length and using an additional two and one -half feet gravel above minimum amount (6 °) under the Davis Property 1281 County Road 103, Garfield County, CO Septic System Site Evaluation and Design Recommendations October 14, 1996 Page 4 distribution lines. This provides more effective sidewall area and takes advantage of the more permeable soils at depths of up to five feet. • Two shallow gravel trenches, each 83 ft. in length and using an additional two and one -half feet gravel above minimum amount (6 ") under the distribution lines. • Three shallow graveless "INFILTRATOR " leaching chamber trenches, each three feet wide and 57 ft. in length and containing nine sections of chamber per trench. • Two shallow graveless "INFILTRATOR " leaching chamber trenches, each three feet wide and 88 ft. in length and containing fourteen sections of chamber per trench. Selection of the preferred alternative trench arrangement depends upon final building locations, topography, the amount of native vegetation that needs to be removed, and the minimum setback distances from features such as the well head, foundations and water supply lines, as specified in the code. Limitations: This report has been prepared according to generally accepted practices in this area for use for sewage disposal design purposes. The conclusions and recommendations submitted in this report are based upon data obtained from our site visits at the location indicated. There is some possibility that the nature and extent of variations in the subsurface soils across the site may not have been evident at the time of this investigation, and may need additional evaluation if further excavation reveals conditions different from those described. This office should be advised of any unusual situations as soon as possible so we may reevaluate our recommendations. If you have questions or if we may be of further assistance, please call the office. Sincerely, Robert F.
