This report presents the results of a Soils and Foundation Investigation for the proposed structure to be constructed on Lot 47.. Cordillera, Filing No. 2, Eagle County, Colorado. The investigation was prepared by means of test borings, test pits and laboratory testing of samples obtained from the borings. The purpose of this foundation exploration was to determine. the Varicsuc sail profile components and the engineering characteristics of the foundation materials, and to provide criteria for use by the design engineers and architects in preparing the foundation design, from a geote.ahnical point of view. MITE LOMIXON AND DUCRIMON The site is 11.1 acres lot located at the and of Ahambra Roan, on the north side of the road, of'f of Cordillera way in the Cordillera Subdivision, Eagle County, Colorado.

The topography of the lot within the building envelope is moderate. Drainage is to the west. The vegetation consisted of sage brush, shrubs, grassand small aspen tress. sTx®&Zxa N The field investigation performed, on September 9, 1993, consisted of drilling, logging and sarpling 2 test borings. The locations of the test borings are shown on Drawing No. 1. The test borings were drilled with a 4-inch diameter, oontinuousi3 flight power auger. Summaries of the test boring logs are detailed on Figures No. 1 & 2. On September 10, 1993, a. deep test pit was dug near the proposed leachf ield area. The teat pit was excsvated with a conventional backhoe. Summary of the teat pit lag is shown on Figure No. 3. Laboratory samples were obtained at selected intervals by advancing a California sampler with a 140 pound hammtaer, falling free 30 inches. . These samples were returned to our laboratory, inspected and classitied in accordance with the unified Soil Classification System and tho test pit logs were edited as necessary. To aid in classifying the soils encountered, and to datermine general soil characteristics, 6e100ted laboratory tests (moisture oontent, unit waight, swell, consolidation) were .perfo ed on representative soil samples. Summaa7rion of the test results are shown on Figures No. 4 and 5. r c- i w—au f a l l arm r 11CLOUN U.

Subsurface conditions are fairly uniform, Boring No. I had 2 feet of topsail over 6 feast Of Clayey SILT over 5.5 feet of course SAND over SHALE bedrock. Boring No. 2 had I font of topsoil over 2.5 feet of SILT over clayey SHALE bedrock to the maximum depth explored of 15 feet. Test Fit No. 3 had 2 feet of topsoil over 6.5 feet of SILT. We understand that no overlot grading has been dome prior to this iliv+estigation. No groundwater was encountered in any of the test pits at the time of excavation. indexes to Geological Mapping, Eagle , ccs}�;;+�'°� prepared by Charles S. Robinson & Assaciat*s,. Inc„, in 1975, states that soils in this area may contain minerals in variable anounts3 that produce serious detrimental effe,ata on concrete, metal or other substances that are in contact1with the moils. Type 11 cement should be used in all concrete that will be in contact with the soil. These maps also state thet soils in this area may be subject to subsidence due to hydro»compaOtfon in low density soils. The underlying bedrock is Eagle Valley Rvaporiter which contains water soluble salts. Solution of these salts can produce sinkholes and general area subsidence. There were, no sinkholes observed at the site at the time of the investigation. -•-- r r r t v v f V I V r 1.1 1 • 1-1,iviv a moovv ,4urnpiunitiyueve i opmenti i; b A No specific design data has been provided, but for the purpose of this analysis, it has been presumed that the proposed residence will consist of 2.floors with a basement, and that loads will be light. if the proposed project differs significantly from this mnderstanding, a review should be made after the plans are more complete. FOUNDAT _R Mi�ENDATI SILK', weathered sandstones and SHALE bedrock, will be encountered in the foundation excavation. The proposed residence should be founded on conventional type spread footings designed for a maximum soil bearing pressure of 3,000 pof. At this pressure, settlements are antioipated to be approximately one inch. The footings should be constructed on the undisturbed SHADE bedrock. The footings excavations should be relatively smooth, free of debris, organics, loose soil, frost, and standing grater. Any over - excavations should be backf.illed 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 oontacted to inspect the foundation excavation to verify that the soll 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 ar minimum of 48 inches of backfill for frost protection. - - P i. I+ QV i v- I Vrm IYGLJVIV HJou1j,-uommunityueve I opment i 7 I 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 100 percent of standard proctor density (ASTIM D-698) within .2. percent of optimam moisture. BYe�H c�DI�YSTRi��T OAT All excavations made for the foundations must be properly backfilled with suitable material compacted to a minimum, of 95 percent of the maximurn standard Proctor density (ASTH D-698) . The on -site sails, exclusive of topsoil and organiast are su' itable for use as backf ill. Before the backfill is placed, all water and loose debris should be removed from these excavations. Prior to the construction of concrete floors, the undisturbed subgrade should be goof compacted with a loaded rubber -tired loader to a uniform high density. Special care should be taken in areas where underground utilities have been installed. The floor slabs should be reinforced, and joints should be provided at the juractione. of the slab and the foundation walls, so that a small amount of independent movement can occur without causing damage. The slabs should be scored in accordance with the American Concrete Institute's recommendations to control cracking. A granular mat (- 3 f 4 inch gravel, with lose than 5 percent passing No. 200 sieve) should be provided below the floor slabs. This should be a minimum of four inches in thickness and compacted. The purpose of this granular mat is to provide a capillary breaX .. , 1166Wv,e V 19%,,,vv,wviviauuria�yUUVVIUPMUnL;i; C A between the subgrade and the slab. 990MMNATER AND 12RAIN Sjgj X While no ground water was encountered 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 a -prolonged period of rain. A foundation perimeter drain as detailed on Figure No."5 is recommended to reduce the risk of surface water infiltrating the footing subsoils. REI The foundation shoul,d.be well reinforced and rigid enough to withstand differential settlements. Foundation walls retaining earth should be resigned to resist an equivalent fluid pressure of 45 pcf for an "active"' case assuming a. level drained backf ill condition. CRAWL SPACE COVVA When moist soils are encountered in the excavation, the ground surface in crawl apace areas should be covered with,an. impervious moisture barrier sealed against the footings. This will help to reduce humidity in the crawl space area. '4� 7 MAINA(iE The backfill placed around the foundation 'Walls must not settle after completion of construction and the top one foot of the jbackfill material must be relatively impervious. The on -site soils, exclusive of topsoil and organics, are suitable for use as backfill. 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 standard Proctor density. `Surface water running toy.*ard the structure from upslope areas should be diverted around and away from the building by means of i 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 9,9 recommended. Downspouts and sill cocks should discharge into splash blocks that extend beyond the limits of the backfi.11. The 4se of long downspout extensions in place of splash blocks in advisable. LAWN IRRIGATION Do. not Ainstall sprinkler systems next to foundation walls, porches or patio slabs. If sprinkler systems are installed, the aprinkler heads should use place so that the spray from the heads, under full pressure, does not fall within five feet of foundation s #; 4uawdo j an00A4TUnWW00F 'OOSS`d 78 NO:! 19M ° w�1,! !
