SAN JOSE, CALIFORNIA 95112 July 17, 1975 Project 1757-1 Saratoga Foothills Development Corporation 1745 Saratoga Avenue - Suite B San Jose, CA 95129 Attention: Mr. Bernie Turgeon Subject: Supplemental Recommendations Geotechnical Investigation Vista Gardens, Residential Development Cupertino,, California Gentlemen: (408) 2 9 7 - 6 9 6 9 i s )p5 In 1974, TERRATECH performed a Geotechnical Investigation of the site of your presently proposed Vista Gardens Development, in Cupertino, California. At the time of our investigation, the proposed development was known as "Vista West", and two story residential structures were planned. With the recent change from "Vista West" to "Vista Gardens", the development plans have been changed also. Now, single story residential structures are planned. The foundation recommendations that we made originally for two story structures should now be changed to recommendations for single story structures. Consequently, the section on Building Foundations in our original report, should be deleted and the following section substituted: :Building Foundations The proposed single story frame residential buildings may be supported on conventional shallow foundations bearing on competent native soil or compacted structural fill. Continuous reinforced concrete footings may be designed to impose pressures on foundation soils up to 2.0 kips per square foot from dead plus normal live loading, provided the resulting foundation width is not less than 12 inches.; Exterior continuous footings should be embedded at least 12 inches below rough pad grade or adjacent finished grade, whichever is lower. Embedment depths for interior footings may be reduced to 8 inches. • July 17, 1975 Project 1757-1 - 2 - All allowable foundation soil pressures given in this section may be increased by one-third when considering additional wind or earthquake forces. During construction, care must be taken to prevent drying of foundation subgrade soils. The construction sequence should be planned to minimize the time intervals between foundation excavation and concrete placement. Concrete should be placed only in foundation excavations that have been kept moist, free from drying cracks, and contain no loose or soft soil or debris. Very truly yours, TERRATECH, INC. AtJoPDennis DJ:ks T E R R A T E C H LEGEND 4 Approximate Location of Exploration Borings , Drilled February,1974 SITE PLAN VISTA WEST CUPERTINO , CALIFORNIA SCALE 0 10 2d 3d 40' so eon PROJECT1757 TERRATECH Q co MARCH ,19741 oLOTECHNICAL INVESTIGATION O VISTA WEST RESIDENTIAL DEVELOPMENT CUPERTINO, CALIFORNIA INTRODUCTION The 2.6(±) acre site is approximately square in plan and has a 369 foot frontage on the west side of Vista Drive beginning approximately 260 feet north of Stevens Creek Boulevard. The proposed development will consist of 18 separate two story frame residential buildings. INFORMATION PROVIDED A preliminary site plan was provided to us by Dick Finnegan, Inc. Building Designers.and Land Planners. Plan #74/21, undated, scale.l" = 20' shows the general layout of the proposed development. This plan was used to prepare the drawing on the opposite page which also shows the locations of our 3 drill holes. OBJECTIVES The objectives of this investigation were: 1. To explore, sample, and classify the foundation soils to such depths as will be significantly influenced by the proposed construction. 1 2. To perform laboratory tests on selected soil samples to determine their pertinent index and engineering properties. 3• Based on the finidngs of 1 and 2, to make general recommendations for site preparation, excavations, grading and compaction; to present geotechnical design parameters for building foundations, ' and concrete slabs -on -grade; to design pavement sections for parking areas; and to advise on surface drainage and landscaping. 4. To prepare this report presenting our findings and recommendations. FINDINGS ' Surface Conditions The property is essentially flat and supports a light growth of weeds and grasses. The southern two thirds of the site is covered with I to 2 feet of fill, ' including scattered concrete fragments, chunks of asphalt, and miscellaneous debris. A large pile of fruit boxes and fruit drying racks are stacked in the northeast corner of the site that is covered with an asphalt pavement. The extreme northeast corner of the property contains an old house foundation ' and concrete floor slab. T E R R A T E C H March 7, 1974 S • Project 1757 2 - tSubsurface Conditions Within the 60 feet maximum depth of our exploration, the site is underlain by medium dense to very dense poorly graded clayey SAHD,,containing some gravel. These clayey sands grade to clayey gravel at an approximate depth of 30 to 35 feet. Groundwater was not encountered in any of the 3 drill holes. Drill hole logs are appended together with the results of laboratory tests performed on selected soil samples recovered from the borings. RECOMMENDATIONS Site Preparation All deleterious material such as old foundations, slabs, asphalt, and the debris scattered over the southern two thirds of the property should be removed from the site. 1 Depressions and.loose soil zones resulting from the removal of trees or underground structures should be carefully backfilled with thoroughly compacted on -site inorganic soil. ' The surface of the site should then be stripped to remove surface vegetation and organic topsoil. Soil containing more than 2 percent by weight of organic matter should be considered organic. Stripping depths should be decided in the field at the time of construction but for planning purposes an average stripping depth of 4 inches should be ' assumed. Strippings may be either wasted off -site or stockpiled for subsequent use in landscaped areas. Grading and Compaction 1 In developing our recommendations we have assumed grading elevations will be designed so that "cut and fill" in on -site native soils is balanced, and that no import fill will be required. Stripped soil surfaces in those areas to receive structural fill, foundations slabs -on -grade, or pavements should be scarified to a depth of at least 4 inches, conditioned with water (or allowed to dry) to produce a soil -water content of 2 percent above the optimum value and then compacted to a density equivalent to at least 90 percent of the maximum dry density of the soil as determined by ASTM Test D1557-70. The appended compaction test curve may be used as a ' guide in calculating the soil -water contents and densities to be achieved. 1 T E R R A T E C H ' March 7, 1974 Project 1757 -3- Structural fill using on -site inorganic soil should be placed in layers not exceeding 8 inches loose thickness, conditioned with water (or allowed to dry) and compacted to the requirements described previously. For purposes of calculating grading elevations and fill volumes assume that loose soils in the upper 12 inch surface zone will decrease in volume by about 20 percent when used as structural fill or compacted in -place. Denser soils below this surface zone will decrease in volume by about 10 percent when used as structural fill and will compress about 0.1 foot when surface compacted in -place. Utility trench excavation should be readily accomplished with conventional mechanical equipment. Excavations of normal depth should not encounter groundwater. Vertical trench excavations up to 5 feet deep should be capable of standing with minimal bracing for short construction periods. Attention is drawn to the State of California Safety Orders dealing with "Excavations and Trenches", which specifies bracing for trenches deeper than 5 feet. For purposes of this report, backfill is defined as material placed in a 1 trench starting 1 foot above the pipe or conduit or at the top of concrete formed around the pipe or conduit;' and bedding is all material placed in a trench below the backfill. ' Unless concrete bedding is required around utility pipes or conduits, imported free -draining sand should be used as bedding. Sand bedding should be jetted or ponded into place and compacted by mechanical means to a density equivalent to at least 95 percent of the compaction test maximum. (ASTM D1557-70). Sand proposed for use as bedding should be tested in our laboratory to determine its suitability. Jetting or ponding of sand bedding should be closely 1 supervised and provisions made for the removal of excess water. in general trench backfill should be placed in horizontal layers not ' exceeding 6 inches in loose thickness and compacted by mechanical means to the requirements given below. The upper two feet of the trenches should be backfilled with on -site ' inorganic soil, free from rocks or lumps larger than 3 inches in greatest dimension, compacted to a density equivalent to at least 90 percent of the maximum dry density of the soil as determined by ASTM Test D1557-70. ' On -site inorganic soil or suitable imported soil compacted to a density equivalent to at least 90 percent of the compaction test maximum (ASTM D1557-70), may be used as backfill in the lower parts of the trenches. Imported soil should be 'inorganic and non -expansive. ' T E R R A T E C H 0 Is March 7, 1974 Project 1757 -4- Building Foundations The proposed 2 story frame residential buildings may be supported on conventional shallow foundations bearing on natural soil or compacted structural fill. Continuous reinforced concrete footings may be designed to impose pressures ' on foundation soils up to 2.5 kips per square foot from dead plus normal live loading. Strip footings should be embedded at least 15 inches below rough pad grade or adjacent finished grade whichever is lower. Individual reinforced concrete foundations, such as may be used for supporting interior columns, may be designed to impose pressures on foundation soils up ' to 3 kips per square foot. These foundations should be embedded at least 18 inches below rough pad grade, or adjacent finished grade, whichever is. lower. ' All allowable foundation soil stresses given in this section may be increased by one third when considering additional wind or earthquake forces. ' During construction, care must be taken to prevent drying of foundation subdrade soils. Construction sequence should be planned to minimize the time interval between foundation excavation and construction. Concrete ' should be placed only in foundation excavations that have been kept moist, are free from drying cracks, and contain no loose or soft soil or debris. Concrete Slabs -On -Grade Concrete floor slabs should be constructed on compacted soil subgrades prepared as described in the section "Grading and Compaction". Where floor dampness must be minimized, a minimum 4 inch section of capillary break material covered with a membrane vapor barrier should be placed between the floor slab and the compacted soil subgrade. The capillary break should be free draining, clean gravel or rock, such as 3/8" pea gravel or permeable aggregate complying with California Standard Specifications, Section 68, Class I, Type A. The material proposed should be tested in our laboratory to verify its effectiveness as a capillary break: The membrane vapor barrier should be at least.10 mil thick polyethylene or its equivalent. If the membrane is protected by a 2" thick layer of sand, its thickness may be reduced to 6 mil. T E R R A T E C H ' March 7, 1974 Project 1757 -5- ,1 ' Where floor dampness is not objectionable, concrete slabs may be laid directly on the compacted soil subgrade. Vehicle Pavements Pavement sections 4A and 4B were designed for automobile and light commercial traffic only, using an assumed Traffic Index of 4.0 and a measured R Value of 23, ' For heavier traffic in terms of either high volume or heavy wheel loadings a deeper pavement section should be used. Alternate pavements for a Traffic Index of 5,0 (pavements 5A 6 5B) and a Traffic Index of 6.0 (pavements 6A & 6B) have been designed and are tabulated below.

Aggregate used for all asphalt concrete should at least comply with the requirements specified in Section 39 for Type B Aggregate. Aggregate used for asphalt concrete surfacing should conform to the grading specified in Section 39 for # inch maximum, medium grading. TE RR.ATEC H s March 7, 1974 Project 1757 -7- Surface Drainage and Landscaping Surface drainage gradients should be planned to prevent ponding and to direct surface water away from building foundations, slabs, edges of pavements, and towards suitable collection and discharge facilities. Concrete splash blocks and channels should be provided beneath downspouts to carry rainwater away from building foundations. Pavements should be designed with surface gradients of at least 2 percent in their principal directions of drainage. Water seepage or the spread of extensive root systems into the soil subgrades of foundations, slabs or pavements could cause differential movements and consequent distress in these structural elements. The landscape designer should be advised of this and should arrange his design accordingly. Observation and Testing During Construction We recommend that TERRATECH be commissioned to assist with the control of the geotechnical elements of project development by observation and testing during construction and particularly to undertake the following: Observe site stripping and advise on stripping depths. Observe, test and advise on scarifying, water conditioning and compaction of cut and fill in areas to receive foundations, slabs -on -grade, or pavements. Observe, test and advise on utility trench backfilling. LIMITATIONS Changes in type, size, number or location of proposed structures or other development details or facilities will render our recommendations invalid unless such changes are reviewed by our staff and our specific recommendations modified accordingly. Our recommendations have been made in accordance with the geologic and foundation engineering principles and practices generally employed by the engineeirng profession. They have been based upon data obtained from field explorations made at the locations indicated on the site plan. Subsurface exploration of any site is necessarily confined to selected locations, and conditions may and often do vary between these locations. Should varied conditions come to light during project development, additional exploration testing and construction modification may be required. To compare the generalized site conditions assumed in this report with those T E R R A T E C H I. ' a e 1 March 7, 1974 Project 1757 -8- found on the site at the time of construction, all earthwork and associated operations should be observed by our field representative and tested where 1 necessary. Any person concerned with this project who observes conditions or features of ' the site or its surrounding areas which are different from those described in this report, should report them immediately to this office for evaluation. r SUMMARY The soils underlying this site should be capable of supporting the proposed development, provided the recommendations of this report are carefully followed. It is important that all earthwork and associated 'operations be observed by our field representative and tested where necessary to check compliance with our detailed recommendations. Final grading plans, earthwork specificaitons and foundation details should be reviewed by our staff prior to start of construction. REPORT PREPARED BY: DJ:ks REVIEWED BY: d' Way E.
