This report presents the findings, conclusions, and recommendations of our Updated Geotechnical Investigation for the proposed house at 11593 Upland Way, Cupertino, Santa Clara County, California. The scope of work performed for this investigation included a project site soils reconnaissance; the excavation, inspection, and logging of one exploratory soil boring to investigate subsurface soils conditions; recovery *of representative samples from the boring; performance of laboratory testing to investigate the physical and engineering properties of the sample; soils engineering analysis of the data gathered during the investigation; and preparation of this written report summarizing the findings, conclusions, and recommendations based upon the investigation. The data obtained and the analyses performed were for the purpose of investigating the strength characteristics of the soils at the project site as a basis for. making design recommendations for the construction of a proposed new house. This investigation is not and shall not be understood or construed to be a.geologic or environmental investigation or investigation of geologic or environmental conditions at or affecting the project site. PROJECT SITE DESCRIPTION The project site is located at 11593 Upland Way in .the city of Cupertino, California. It is a rectangular shaped parcel of approximately one third of an acre, bounded on the east by Upland Way, and on the north, south, and west by residential lots. Plate 1 is the Site Vicinity Map. Topographically the project site is an area characterized by gentle slopes. The elevation of the property is approximately 400 feet (above Mean Sea Level). Vegetation at the project site consists of some native deciduous trees, native grasses, and weeds. Drainage of the lot is by sheet, flow to the city sewer system and eventually to the ASSOCIATED TERRA CONSULTANTS, Inc. Page 1 File: 177631 April 20, 2000 northeast toward Regnart Creek. This creek flows northward where it joins up with other. - small creeks, and eventually empties into the San Francisco Bay. (FIELD INVESTIGATION The field investigation consisted of a surface. site reconnaissance, and the excavation, inspection, and logging of one exploratory boring at the approximate location shown on the Site Plan (Plate 2). The exploratory boring was logged and sampled on February 4, 2000, by our Staff Engineering Geologist, under the direction of the Soils Engineer. Representative soils samples were taken from selected depths in the boring using standard 2 -1/2 -inch ID brass liners six inches long. Upon completion of this field investigation, the excavations were loosely backfilled with native soils. SOILS AND BEDROCK CONDI'T'IONS Soils and Artificial Fill - Detailed logs and descriptions of the soil units encountered are contained in the Log of Boring B-1 (Plate 3). The surficial unit encountered was an approximately 6 -inch thick layer of baserock, used in the construction of the temporary gravel driveway. The underlying unit was a sandy clay, reddish brown in color, with minor amounts of gravel, approximately 7 feet thick. It was slightly .damp with moderate plasticity and a hard consistency. The unit beneath the sandy clay was another sandy clay, darker brown in color, damp to moist; and a high plasticity. This unit became increasingly sandy with depth, until another unit was determined to be present at approximately 15 feet. This unit, a sandy clay, was brown in color, moist, and with a high plasticity and a hard consistency. The boring was terminated at 16-1/2 feet: No free groundwater was encountered in the boring. The units found in this boring, B1, correspond very well with borings logged by Lee Engineers in May of 1991. Detailed logs and descriptions of the soil units encountered are contained in the Logs of Prior Exploratory Borings TB1, TB2, and TB3 (Plate 4). These borings were drilled to various depths. TB1, the deepest boring, was drilled to a depth of 31 feet. No groundwater was encountered in any of these borings. Bedrock - No bedrock was encountered during borings. Ground Mater and Springs - Free ground water was not encountered in any of the excavations, and no indication of shallow ground water was observed in the field. ASSOCIATED TERRA CONSULTANTS, Inc.

Page 2 File: 177631 (LABORATORY INVESTIGATION April 20, 2000 A laboratory -testing program was performed to investigate the physical and engineering properties of the soils at the project site. All the samples recovered were tested for moisture content and dry density. One direct shear test was performed on a selected sample to help investigate the strength characteristics of the soils. A summary of the test results is presented in Tables A. CONCLUSIONS AND RECOMMENDATIONS General 1. The project site is suitable for the construction of the proposed house, provided the recommendations set forth in this report are incorporated into the design considerations, and project plans and specifications. Existing project site organic -free soils can be used at the direction of the Field Engineer. 2. This investigation' and report are, not and shall not be construed to be a geologic or environmentalinvestigation or investigation of geologic or environmental conditions at or affecting the project site. Grading 3. We do not anticipate that extensive grading will be performed during the proposed construction, but have included 'recommendations here for the placement of fill and control of any grading operations at the site. All fill placed on the site shall be compacted fill. 4. We did not observe any subsurface structures, but should they nevertheless exist in the area to be graded, they and any surficial structures that will riot be a part of the final development shall be removed prior to any grading, operations. This includes such things as septic tanks, trenches, concrete blocks., asphalt, foundations, utilities, or, pipelines. These objects shall be accurately located- on the grading plans to assist the Field Engineer in establishing proper control over their removal. 5. All organic surface material and debris, including grass or weeds, approximately four to six inches deep shall be stripped prior to any grading operations from alt. areas that are ASSOCIATED TERRA CONSULTANTS, Inc. Page 3 File: 177631 April 20, 2000 to receive engineered fill. The exact depth of required stripping shall be determined in the field. These organically contaminated soils may be stockpiled for later use in landscaping. ping. 6. Depressions left by the removal of any surface and subsurface structures shall be cleaned of all debris and backfilled with compacted engineered fill:The material shllplaced in lifts not exceeding eight inches in uncompacted thickness and compactedatoba minimum degree of compaction of 90 percent as determined by ;the ASTM D1557 procedure (current edition). The upper six inches of subgrade soil beneath pavements shall be compacted to a minimum of 95 percent. This operation must be conducted observation of Associated Terra Consultants, Inc.. under the 7. After removing all subsurface structures, and after stripping off the organically contaminated surficial soil, the areas that will receive fill shall be ripped by machine to an average depth of at least 12 inches and thoroughly stripped of roots, vegetation, and oth ' deleterious matter. er 8. Following the structure removal, stripping, and ripping operations, the native soil, wherever fill will be placed, shall be properly compacted as engineered fill° All uncompacted or loose fill material present on the project site shall be ovexcavated and recompacted before placement of any engineered fill. Subgrade Preparation 9. After the project site has been properly cleared and stripped and the necessary excavations made, the exposed surface native soil subgrade shall be scarified to a minimum depth of six inches, moisture conditioned with water to at least three percent above the laboratory established optimum moisture content, and compacted to at P P least 90 percent compaction as determined by the ASTM D1557procedure (current edition). 10. All engineered fill, whether native or' imported soil, shall be placed in uniform horizontal lifts of not more than eight inches in uncompacted thickness. Imported soils materials shall be compacted to not less than 90 percent. relative compaction in accordance with the ASTM D1557 procedure. Native soils materials shall be moisture - conditioned with water to at least three percent above the optimum moisture content and compacted to between 87 and 92 percent compaction as determined by the ASTM D1557 procedure. Before compaction begins, the fill shall be brought to approximate optimum moisture content that will permit proper compaction by either: (1) aerating the material f it is too wet, or (2) spraying the material with water if it is too dry. Each lift rY shall be ASSOCIATED TERRA CONSULTANTS, Inc. Page 4 r File: 177631 April 20, 2000 thoroughly mixed before compaction to assure a uniform distribution of water content. When fill material includes rocks, nesting of rocks will not be permitted, and all voids must be carefully filled and properly compacted. No rocks larger than four inches in diameter shall be used for the top two feet of fill. 11. Imported soils materials shall be a soil or soil -rock mixture which is free from organic matter or other deleterious substances and have a plasticity index less than 12. The fill material shall not contain rocks or lumps over six inches in greatest test dimension, and not more than 15 percent larger -than two and one half (2-1/2) inches. Materials from the project site, if free of organic matter or other deleterious substances, are suitable for use in fills except where select material is required. All imported borrow must be approved by Associated Terra Consultants, Inc. before,being brought to the project site. Grading Inspection 12. Associated Terra Consultants, Inc. must perform the necessary inspection services during construction of this project to ensure uniformity with the conditions upon which these recommendations are based. Associated Terra Consultants.: IInc.. shall be notified at least two days before any grading begins at the project site to coordinate works in the field with the contractor. Treatment After Completion of Grading 13. After grading is completed and the Field Engineer has finished his observation of the work, no further excavation or filling shall be done except with the approval of and under the observation of the Field Engineer. 14. It shall be the responsibility of the Grading Contractor to prevent erosion of freshly graded areas during reconstruction and until such time as permanent drainage and erosion control measures have been. installed. Utility Trench Backfill 15. Underground utility trenches shall be backfilled;vvith compacted engineered fill. If on- site soils are used, the material shall be placed„ in lifts not exceeding eightinches in uncompacted thickness and compacted to.a rr nirnum of 00 percent relative compaction by mechanical means only. Imported sand may be used for backfilling trenches provided it is compacted to at .least 90 percent relative compaction. In all building and pavement ASSOCIATED TERRA CONSULTANTS, Inc. Page 5 File: 177631 April 20, 2000 Drainage 22. It is extremely important that strong measures are taken to control and conduct all surface arid -subsurface waters -away from the structures on the site so that they do not adversely affect the foundations of the structure, and that all drainage facilities be diligently maintained. This is extremely important during periods of prolonged and intense rainfall. g nse 23. .Only plants requiring q g minimal. water should be planted within five feet of the foundation(s), and they should be provided with a watering system that delivers only the minimum amount of water necessary, for proper and healthy plant maintenance and growth. For example, a drip watering system that can be adjusted to deliver the appropriate amount of water. We recommend that someone' knowledgeable aboutlant species be consulted in this matter. P 24. Where concrete walkways or other impermeable structures or barriers may obs truct efficient flow, adequate provision must be made such that all water flows freely way from the. structures and no ponding occurs. This is especially important injacent to foundations. areas adjacent 25. Flow of water on slopes shall not be permitted. Diversion drainage' berms or interceptor v -ditches shall be constructed at the crests of all new slopes to prevent this. The surfaces of the slopes shall be compacted to provide surfaces free of loose material and be planted with erosion control mix or finished landscaping as soon as possible after completion of construction. 26. Roof drainage downspouts shall be discharged into controlled drainage facilities to keep the water away from the foundations. Mose outlets and wateringsystems shall b arranged in such a way as to prevent excessive moisture from reaching foundation areas, and to safely dispose of the water into an area equipped with suitable energy-dissi atin devices, to prevent adverse erosion and effects on slope stability. Sure drama e systems shall not discharge into the ground. g 27. The final grade shall result in aositive p gradient of at least two percent. (2%) away from the foundation in order to provide rapid removal of storm water and to prevent ponding of water adjacent to the foundation or slabs -on -grade. Six inches of soil may be backfilled against the exteriors of the foundation and °graded so that it will assist ' y removal of the water. m the ASSOCIATED TERRA CONSULTANTS, Inc. Page 7 File: 177631 April 20, 2000 28. Discharge . locations for all drainage facilities must be chosen carefully and constructed carefully with erosion protection and energy -dissipating devices so as to prevent excessive erosion or slope instability on this and other properties. Future modifications of the project site shall be carefully planned with professional consultation. This is especially true for any construction activity involving water such as landscape irrigation systems and swimming pool system construction. Water Wells 29. Any water wells which may exist in the project site development area and which are to be abandoned shall be capped according to the requirements of the cognizant authority. The final elevation of the top of a capped well casing shall be a minimum of three feet below any adjacent grade prior to any grading operations. Foundation Recommendations 30. These recommendations shall be used for the design of the proposed house. The foundation shall be a combination of drilled friction pier and grade beam construction. Skin friction piers shall be founded a minimum of ten feet deep on a flat surface into competent soils or bedrock materials.. disregarding the first two feet for design purposes. Refusal, if encountered, shall be judged by the Soils Engineer' in the field at the time of drilling. The piers shall be designed for a skin friction of 500 psf, not including the top two feet. All piers shall have a minimum diameter of 16 inches, and the spacing of the piers shall be a minimum of at aeast three times the pier diameter. These values are for dead plus live loads and may be increased by one-third to include short-term seismic and wind effects. Each pier shall be reinforced with a minimum of four #5 bars vertical,for its full length, with the reinforcements of the piers tied to the top reinforcement of the grade beams. If the final grade of the building pad is steeper than existing, Associated Terra Consultants, Inc. shall be notified for possible supplemental recommendations. 31. Grade beams shall extend a minimum depth of six inches below adjacent pad grade and shall be reinforced with a minimum of four, #4 bars, two near the top and two near the bottom. The final design of the foundation and reinforcing required shall be determined by the Structural Engineer responsible for the foundation design. 32. " Overpour" and concrete leakage shall not, be allowed. ASSOCIATED TERRA CONSULTANTS, Inc. Page 8 File: 177631 April 20, 2000 33. We do not anticipate appreciable settlements, however slight settlement shall be considered in the designs of the foundation and retaining wall(s). Slab -on -Grade Construction 34. Where slabs -on -grade are to be constructed, we recommend that the slabs be supported on a minimum of 18 inches of compacted, non -expansive structural fill. Preparation of the natural subgrade soils and ,placement of the structural fill materials shall be performed in accordance with the preceding recommendations under "Grading." Prior to final construction of ,the slabs, the subgrade surface shall be compacted to provide a smooth, firm surface for slab, support. Slab subgrades shall not be allowed to dry and. all surface shrinkage cracks shall be sealed by soaking prior to slab construction. Slab reinforcing shall be a minimum of #3 rebar at 18" center -to -center both ways, and shall be ;provided in accordance with the anticipated use and loading of the slab, as designed by the Structural Engineer. Slabs shall be provided with an expansion joint at least every eight feet. If the slabs are to be subjected to heavy loading, a subgrade modulus for the on- site soils and fill materials of 150 pounds per cubic inch is considered applicable for design. Some movement of the slabs can be expected, and slabs must be structurally independent of all other structural members. Care must be taken to ensure that the soils beneathslabs keep a constant moisture. Alternatively, the top five feet may be removed and replaced with properly compacted, non -expansive fill. Associated Terra Consultants, Inc. must be contacted for supplemental recommendations if a slab is to be constructed on top of an area underlain by artificial fill. 35. In areas where floor dampness is undesirable, such as inside a new structure house, a moisture barrier shall be used. One generally effective system for use in areas not subject to heavy vehicle loading is to install a capillary break consisting of four inches of free - draining pea gravel beneath the slab. In order to minimize vapor transmission, an impermeable membrane shall be placed over the gravel. The membrane shall be, covered with a' two-inch layer of sand to aid in curing the concrete and to protect the membrane during construction. The sand shall be slightly moistened just prior to concrete pouring. The combined thickness of gravel, membrane and sand may be considered as the upper six inches of the previously recommended non -expansive fill beneath the slab. Uniform building Code Seismic Design Criteria 34. The site is in the Uniform Building Code (1997) Seismic Zone 4. Active or potentially active' faults near the site and their potential- earthquake (moment) magnitudes are listed ASSOCIATED TERRA CONSULTANTS, Inc.
