The exposed soils in the infiltration trench consisted of a silty, gravelly, SAND and were found to be consistent with the soils anticipated in the Soils and Foundation Report prepared for you dated March 7, 1996. The system was visually inspected for conformance to the plans and documents. . Two variances to the plan were noted, the substitution of the 1250 gal. two compartment septic tank with a larger 1500 gal. two compartment septic tank and the infiltration field was moved approximately 10' west, further from the - Domestic well than shown on the plan. The placement of the system was in substantial compliance with the Septic System Design dated April 5, 1996, by Inter -Mountain Engineering.

We understand that a two story residence wood frame residence is planned. The subdivision, River's Bend Filing No. 1, is located in the Colorado River Canyon and appears to consist of some alluvial deposits. Two soil test borings were performed to help determine foundation design parameters The site has a topsoil 'layer Of approximately 6 inches irn thickness which is underlai by approximately 6 to .7 feet`6k redbro' tong t brown , slig�htgrae Iy,silty,4SAN At depths of 6 to 7 feet reddish" brown, slight y gravelly to very gravelly; SAND was`encountered. The foundations for at the site may be designed as conventional spread footings with a bearing pressure of 2000 psf. : Three percolation test holes were bored on the site to determine the percolation rates. In the area of the proposed septic field, three percolation tests were performed with percolation rates ranging from 16 to 35; minutes per inch: SCOPE This report presents the results of a Geotechnical Investigation for the proposed residence to be constructed on Lot 4, River's Bend Filing No. 1, in Eagle County, Colorado. The investigation was performed by advancing soil test borings, obtaining soil samples for laboratory testing, performing percolation tests, and presenting our findings in this report. The purpose of this foundation exploration is to evaluate the soil for foundation support, and the engineering characteristics of the foundation materials, and to provide criteria from a geotechnical perspective, for use by the owner in preparing foundation design, grading design, and drainage plans. SITE LOCATION AND DESCRIPTION The site is an undeveloped lot located described as Lot 4, River Bend Filing No. 1 near Sweetwater, Colorado. The site slopes toward the northeast at gradients which are estimated to ranged from 5 to 15 percent. The site is bounded by Colorado River Road A located to the north, and vacant parcels and unplatted property located to the east, south, and west. Vegetation on the site consists of sage brush and sparse grass. The ground surface was partially covered with snow at the time the soil test borings were performed. SITE INVESTIGATION The subsurface exploration included a site reconnaissance by an Inter -Mountain Engineering Personnel and the drilling of three soil test borings to observe the subsurface soil profile and obtain soil samples for laboratory testing. The soils test borings were performed by a track mounted CME 45 drill rig to the depths indicated in the Summary of Test Borings. The test boring locations were established in the field by estimating right angles and pacing distances from site features. The approximate locations of the test boring are illustrated on the Site Plan in the Appendix, refer to Drawing No. 1. The Appendix also contains Summary of Test Borings presenting the information which was obtained in the subsurface exploration, a key to the terms used in the Summary of Test Borings, and a brief description of the procedures used. PERCOLATION RATES The percolation tests were performed on February 16, 1996 in the vicinity of the proposed absorption field, refer to site plan. Three 6-inch diameter percolation test holes were drilled using a 6-inch diameter auger to depths of approximately 30 inches. The approximate locations for the percolation test holes are shown on the site plan, refer to Figure No. 1. The test holes were filled with water 24 hours prior to the actual testing to allow the soils to inundate. The water levels were measured to a relative constant rate. The percolation rates varied from approximately 16 to 35 minutes per inch. Although the percolation test holes and profile pits were dug to obtain a reasonable accurate determination of the absorption field conditions, variations in the subsurface conditions are also possible. Variations that exist beneath the absorption field may become evident during the excavation. A representative form our office should observe I the completed excavation to confirm that the soils encountered are as indicated by the soils profile hole. SUBSURFACE AND GROUNDWATER CONDITIONS The generalized soil stratigraphy is presented below. The stratum symbols and solid lines which are used to illustrate the various strata breaks on the Summary of Test Borings are approximate as the transitions between soil types may occur suddenly or relatively gradual. Underlying a topsoil layer of approximately 6 inched in thickness, a reddish brown to light brown, slightly gravelly, silty, SAND was encountered to depths of 6 to 7 feet. A depth of.6 to 7 feet in borings B-1 and B-2, respectively, the soils transition to a gravelly to very gravelly, silty, SAND. No measurable ground water was present at the time the soil test borings were completed. No long-term ground water observations were made. PROPOSED CONSTRUCTION The project site consists of the construction of a single family residence on the site. The residence is to be of wood frame construction with concrete slab on grade construction for the ground floor. We anticipate that the residence will be a two-story structure with a walk out basement. Foundation wall loading is anticipated to range from 1 to 5 kips per linear foot, and isolated column loading are anticipated to range from approximately 5 to 25 kips. 6 FOUNDATION RECOMMENDATIONS Based upon the results of field explorations and the laboratory testing, we recommend that conventional spread footing foundation system be used. The foundations may be designed for a bearing pressure of 2,000 psf for footings bearing on undisturbed silty SAND. At this pressure, settlements are anticipated to be within tolerable limits for wood frame construction. The footing excavations should be relatively smooth, free of debris, organics, loose soil, frost, and standing water. Any over -excavations should be backfilled and compacted to 100 percent within 2 percent of optimum moisture as determined by a Standard Proctor Test (ASTM D-698). A representative of this office should be contacted to inspect the foundation excavation to verify that the soil conditions are the same as those anticipated in this report. After all of the final grading is completed, the bottom of the footings should be covered with a minimum of 48 inches of backfill for frost protection. Voids left by the removal of cobbles in the bottom of the footing excavation should be filled with lean concrete or a granular soil with a maximum particle size of 3 inches compacted to 95 percent of Standard Proctor Density (ASTM D-698), within 2. percent of optimum moisture. SLAB CONSTRUCTION The on -site soils, exclusive of Topsoil and Organics are suitable to support lightly loaded slab -on -grade construction. All excavations made for the foundations under proposed slab -on -grade areas must be properly backfilled with suitable material compacted to a minimum of 95 percent of the maximum Standard Proctor Density (ASTM D-698). Backfill placed beneath slab -on -grade floors should be installed at -2 to +2% of optimum moisture content. The on -site soils, 2 exclusive of topsoil and organics are suitable for use as backfill. Before the backfill is placed, all water and loose debris should be removed from the excavations. Prior to the construction of concrete floors, the undisturbed subgrade, free from topsoil and organics, should be proof rolled with a loaded rubber -tired loader or similar equipment to densify the near surface soils. To reduce the chance of damage to shallow utilities, special care should be taken in areas where underground utilities are present. The floor slabs should be appropriately reinforced, and joints should be provided at the junctions of the slab and the foundation walls, so that independent movement can occur without causing damage. The slabs should be scored in accordance with the American Concrete Institute's recommendations to help control cracking. GROUNDWATER AND DRAIN SYSTEM While no ground water was reported in the soil test borings at the time the field investigation was conducted, it is possible that seasonal variations will cause fluctuations, or for a water table to be present in the upper soils during the spring months, or after prolonged periods of rain. A foundation perimeter drain as detailed on Figure No. 7 is recommended to reduce the risk of surface water infiltrating the footing subsoils. REINFORCING The foundation should be well reinforced and rigid enough to withstand differential settlements. Walls retaining earth should be designed to resist an equivalent fluid pressure of 30 pcf for an "active" case assuming a level drained backfill condition. For "at rest" conditions such as basement walls, an equivalent fluid pressure value of 50 pcf may be used for "at rest" conditions. CRAWL SPACE COVER When moist soils are encountered in the excavation, the ground surface in crawl space areas should be covered with an impervious moisture barrier sealed against the footings. This will help to reduce humidity in the crawl space area. BACKFILL AND SURFACE DRAINAGE The foundation soils encountered in portions of the site must be prevented from being wetted after construction. The backfill placed around the foundation walls should be methodically compacted to help reduce settlement after completion of construction. The top one foot of the backfill material must be relatively impervious. The on -site soils, exclusive of Topsoil and Organics are suitable for use as backfill. Foundation wall backfill should be moistened or dried to near its optimum moisture content and compacted to at least 90 percent of the maximum Standard Proctor Density. Structural backfill should be compacted to at least 95 percent of the maximum dry density as determined by the Standard Proctor method of test (ASTM D 698). Surface water running toward the structure from up slope areas should be diverted around and away from the building by means of lined drainage swales or other similar measures. The final grade should have a positive slope away from the foundation walls on all sides. A minimum of 12 inches in the first 10 feet is recommended. Down spouts and sill cocks should discharge into splash blocks that extend beyond the limits of the backfill or a minimum distance of at least 5 feet from the foundation wall. The use of long downspout extensions in place of splash blocks is advisable. LAWN IRRIGATION Do not install sprinkler systems next to foundation walls, porches or patio slabs. If sprinkler systems are installed, the sprinkler heads be aligned so that the spray from the heads, under full pressure, does not fall on foundation walls or within five feet of foundation walls, porches, or patio slabs. Lawn irrigation must be controlled and no flooding or ponding of water should be performed. If the future owners desire to plant next to foundation walls, porches or patio slabs, and are willing to assume the risk of structural damage, etc., then it is advisable to plant only flowers and shrubbery (no lawn) of varieties that require very little moisture. These flowers and shrubs should be only hand watered. MISCELLANEOUS The recommendations provided herein are based on experience in the area and from the on -site field exploration. The information obtained from the field exploration and laboratory testing reflects subsurface conditions only at the specific locations at the particular times designated. Subsurface conditions at other locations and times may differ from the conditions at these locations. The extent of any variations between the test pits may not appear evident until excavation is performed. However, only minor variations are expected. If during construction conditions appear to be different, this office should be advised so re-evaluation of the recommendations may be made. This report has been prepared for the exclusive use of Randy Cook for the specific application to the proposed residence to be located on Lot 4, River's Bend Filing 1, Eagle County, Colorado. 10 The findings and recommendations of this report have been prepared in accordance with locally accepted professional engineering standards for similar conditions at this time. There is no other warranty, either expressed or implied. Sincerely,. INTER -MC Richard O. F Geotechnical Engineer EERING, LTD.
