The findings of the investigation, laboratory test results and recommendations for foundation design are presented in this report. From a geotechnical point of view, it is our opinion that the site is suitable for the 0 proposed development, provided the recommendations in this report are implemented during the design and construction phases. However, loose surficial deposits are present on the site which will require special consideration during the design and remedial grading phase. If you have any questions, please do not hesitate to contact us at 755-8622. opportunity to be of service is appreciated.

P-274028 c c c c INTRODUCTION This report presents the results of our geotechnical engineering investigation on the subject property. The purpose of this study is to evaluate the nature and characteristics of the surficial deposits underlying the property and their influence on the construction of a single-family residence. SITE CONDITIONS The subject property includes a flag lot located just west of Elmwood Street, along the north side of Buena Vista Way, in the city of Carlsbad. The flag lot is located behind an existing residence. Access is via a private concrete drive along the west side of the existing residence. The vacant lot descends gently to the west and is covered by a heavy growth of weeds. Several tree stumps were also noted on the property. Drainage is by sheet flow to the west however, significant infiltration appears to occur prior to runoff. PROPOSED DEVELOPMENT Concept plans for the development of the site were prepared by B. Worthing Plan Service. The project will include the construction of a single-family residence in the central portion of the 10,500 square foot lot. It is our understanding that the residence will be supported on conventional continuous wall footings with slab on grade floors. c c March 5, 1998 Page 6 W.O. P-274028 SITE INVESTIGATION c c c Three exploratory borings were drilled on the site to a maximum depth of 9.0 feet. Earth materials encountered were visually classified and logged by our field geologist. Relatively undisturbed and bulk samples of earth materials were obtained at selected intervals. Samples were obtained by driving a thin walled steel sampler into the desired strata. The samples are retained in brass rings of 2.5 inches outside diameter and 1.0 inches in height. The central portion of the sample is retained in close fitting, waterproof containers and transported to our laboratory for testing and analysis. LABORATORY TESTING Classification The field classification was verified through laboratory examination, in accordance with the Unified Soil Classification System. The final classification is shown on the enclosed Boring Logs. MoistureAIensity The field moisture content and dry unit weight were determined for each of the undisturbed soil samples. This information is useful in providing a gross picture of the soil consistency or variation among exploratory excavations. The dry unit weight was determined in pounds per cubic foot. The field moisture content was determined as a percentage of the dry unit weight. Both are shown on the enclosed Appendix A. March 5, 1998 Page 7 W.O. P-274028 c c Maximum Dry DensiDr/Optimum Moisture Content The maximum dry density and optimum moisture content were determined for selected samples of earth materials taken from the site. The laboratory standard tests were in accordance with ASTM D-1557-91. The results of the tests are presented in Appendix "A". GEOTECHNICAL CONDITIONS The subject property is underlain by Pleistocene terrace deposits. The sedimentary unit, in general, is weathered in the upper 1.0 to 1.5 feet but becomes increasing dense with depth. The terrace deposits are overlain by soil deposits. A brief description of the earth materials encountered on the site is discussed below. - Soil Approximately 1.0 to 2.0 feet of dark brown silty sand blankets most of the site. The soil is generally very moist to wet, loose and contains a moderate amount of small roots and organics. However, deeper root systems probably occur in the areas of tree removal. The high moisture content in the soil is the result of infiltration from recent prolonged rains. The contact with the underlying Pleistocene terrace deposits is gradational. Terrace Deposits The site is underlain by Pleistocene terrace deposits. The terrace deposits are composed of reddish brown slightly clayey, fine and medium-grained sand. The terrace deposits are March 5, 1998 Page 8 W.O. P-274028 c c c slightly weathered in the upper 1.0 to 1.5 feet. The weathered zone is very moist due to infiltration from recent rains. Below the weathered zone, the terrace deposits are dense and competent. Expansive Soils Based on previous testing and our experience in the area, the surficial materials and terrace deposits have a potential expansion in the low range. Ground Water No evidence of ground water was observed to the depth explored. However, a perched ground water condition can develop in the loose soil zone and weathered terrace deposits. Typically after development, irrigation water infiltrates the soil and weathered zones and is perched above the dense, less pervious terrace deposits. It should be noted that minor seepage problems may occur after development, as a result of drainage alterations and/or over-irrigation. In the event that seepage or saturated ground does occur, it has been our experience that they are most effectively handled on an individual basis. Faults/Seismicitv Based on a review of published geologic maps, no faults traverse the site. Active faults which could affect the site include the Elsinore, San Jacinto and San Andreas Faults. March 5, 1998 Page 9 W.O. P-274028 c c c c c c c These faults are located 24 to 72 miles east of the site. Off-shore faults, including the active Rose Canyon fault zone are located approximately 3 miles west of the site. The proximity of the site to known faults is shown on the enclosed Regional Fault Map. Although the likelihood of ground rupture on the site is remote, it is almost a certainty the property will be exposed to moderate levels of ground motion resulting from the release of energy, should an earthquake occur along the numerous known and unknown faults in the region. Liquefaction Potential Liquefaction is a process by which a fine sand mass loses its shearing strength completely and flows. The temporary transformation of the material into a fluid mass is often associated with ground motion resulting from an earthquake. Owing to the moderately dense nature of the underlying terrace deposits and the anticipated depth to ground water, the potential for seismically induced liquefaction and soil instability is considered very low to non-existent. CONCLUSIONS 1) No significant geotechnical conditions were observed on the site which would preclude development. However, certain geotechnical conditions should be addressed during the design and construction phases, March 5, 1998 Page 10 W.O. P-274028 c 2) The soil and saturated weathered terrace deposits are not suitable for the support of structural footings or concrete flatwork. 3) In order to provide a more uniform support for proposed footings and slabs, the soil and weathered terrace deposits in the building pad should be removed to a minimum depth of 3.0 feet below the existing grade and replaced as properly compacted fill. The removal depth should be such that a minimum of 18 inches of compacted fill underlies the base of proposed footings. RECOMMENDATIONS c c c Building Pad - Removals/Recompaction The existing soil and weathered terrace deposits should be removed to a minimum depth of 3.0 feet below the existing grade or 18 inches below the base of proposed footings and replaced as properly compacted fill. Removals should include the entire building pad extending a minimum of 10.0 lateral feet beyond the building footprint, where applicable. Deeper removals may be necessary where tree stumps are encountered. With the exception of the upper 2.0 to 3.0 inches of highly organic soil, most of the existing earth deposits are generally suitable for reuse, provided they are cleared of all vegetation, debris and thoroughly mixed. Prior to placement of fill, the base of the removal should be observed by a representative of this firm. Additional overexcavation and recommendations may be necessary at that time. The exposed bottom should be scarified March 5, 1998 Page 11 W.O. P-274028 c to a minimum depth of 6.0 inches, moistened as required and compacted to a minimum of 90 percent of the laboratory maximum dry density. Fill should be placed in 6.0 to 8.0 inch lifts, moistened to approximately 1.0 - 2.0 percent above optimum moisture content and compacted to a minimum of 90 percent of the laboratory maximum dry density. c c c c Imported fill, if necessary, should consist of granular deposits approved by the geotechnical engneer Foundations The following design parameters are based on an anticipated expansion potential in the low range. Footings for the proposed residence and garage should be a minimum of 12 inches wide and founded a minimum of 12 inches and 18 inches below the lower most adjacent subgrade for single-story and two-story structures, respectively. A 12 inch by 12 inch grade beam should be placed across the garage opening. Footings should be reinforced with a minimum of four No. 4 bars, two along the top of the footing and two along the base. Footing recommendations provided herein are based upon underlying soil conditions and are not intended to be in lieu of the project structural engineer’s design. For design purposes, an allowable bearing value of 1500 pounds per square foot may be used for foundations at the recommended footing depths. The bearing value indicated above is for the total dead and frequently applied live loads. March 5, 1998 Page 12 W.O.

A coefficient of friction of 0.35 may be used with dead- load forces. A passive earth pressure of 250 pounds per square foot, per foot of depth of fill or terrace deposits penetrated to a maximum of 1500 pounds per square foot may be used. Slabs on Grade (Interior and Exterior) Slabs on grade should be a minimum of 4.0 inches thick and reinforced in both directions with No. 3 bars placed 18 inches on center in both directions. The slab should be underlain by a minimum 2.0-inch sand blanket. Where moisture sensitive floors are used, a minimum 6.0-mil Visqueen or equivalent moisture barrier should be placed over the sand blanket and covered by an additional two inches of sand. Utility trenches underlying the slab may be backfilled with on-site materials, compacted to a minimum of 90 percent of the laboratory maximum dry density. Slabs including exterior concrete flatwork should be reinforced as indicated above and provided with saw cuts/expansion joints, as recommended by the project structural engineer. All slabs should be cast over dense compacted subgrades. March 5, 1998 Page 13 W.O. P-274028 c Driveway As previously indicated, a concrete drive is present from Buena Vista Way to the southwest portion of the site. The minimum driveway section should be composed of 3.0 inches of asphaltic concrete, over 4.0 inches of Class 2 base. The driveway should be protected from moisture migrating under the pavement section. The soil and weathered terrace deposits in the driveway should be removed and replaced as compacted fill. The upper 12 inches of the driveway subgrade should be scarified, moistened and compacted to a minimum of 95 percent of the laboratory maximum dry density prior to placement of Class 2 base. DrainaneNenetation Specific drainage patterns should be designed by the project designer or architect. However, in general, pad water should be directed away from foundations and around the structure to the street or an approved alternate location. Roof water should be collected and conducted to the street, via non-erodible devices. Pad water should not be allowed to pond. If vegetation in these areas is desired, sealed planter boxes should be considered. Other alternatives may be available, however, the intent is to reduce moisture from migrating into foundation subsoils and under concrete flatwork. Irrigation should be limited to that amount necessary to sustain plant life. Vegetation adjacent to foundations should be avoided. March 5, 1998 Page 14 W.O.

GRAPHIC SCALE 0' 20' 40' APPENDIX B GRADING GUIDELINES c c Grading should be performed to at least the minimum requirements of the governing agencies, Chapter 70 of the Uniform Building Code, the geotechnical report and the guidelines presented below. All of the guidelines may not apply to a specific site and additional recommendations may be necessary during the grading phase. Site Clearing Trees, dense vegetation, and other deleterious materials should be removed from the site. Non-organic debris or concrete may be placed in deeper fill areas under direction of the Soils engineer. Su bdrainaae 1. During grading, the Geologist and Soils Engineer should evaluate the necessity of placing additional drains (see Plate A). 2. All subdrainage systems should be observed by the Geologist and Soils Engineer during construction and prior to covering with compacted fill. 3. Consideration should be given to having subdrains located by the project surveyors. Outlets should be located and protected. Treatment of Existina Ground 1. All heavy vegetation, rubbish and other deleterious materials should be disposed of off site. 2. All surficial deposits including alluvium and colluvium should be removed unless otherwise indicated in the text of this report. Groundwater existing in the alluvial areas may make excavation difficult. Deeper removals than indicated in the text of the report may be necessary due to saturation during winter months. 3. Subsequent to removals, the natural ground should be processed to a depth of six inches, moistened to near optimum moisture conditions and compacted to fill standards. Fill Placement 1. Most site soil and bedrock may be reused for compacted fill; however, some special processing or handling may be required (see report). Highly organic or contaminated soil should not be used for compacted fill. 2. Material used in the compacting process should be evenly spread, moisture conditioned, processed, and compacted in thin lifts not to exceed six inches in thickness to obtain a uniformly dense layer. The fill should be placed and compacted on a horizontal plane, unless otherwise found acceptable by the Soils Engineer. 3. If the moisture content or relative density varies from that acceptable to the Soils engineer, the Contractor should rework the fill until it is in accordance with the fol lowing : a) Moisture content of the fill should be at or above optimum moisture. Moisture should be evenly distributed without wet and dry pockets. Pre- watering of cut or removal areas should be considered in addition to watering during fill placement, particularly in clay or dry surficial soils. b) Each six inch layer should be compacted to at least 90 percent of the maximum density in compliance with the testing method specified by the controlling governmental agency. In this case, the testing method is ASTM Test Designation D-1557-91. 4. Side-hill fills should have a minimum equipment-width key at their toe excavated through all surficial soil and into competent material (see report) and tilted back into the hill (Plate A). As the fill is elevated, it should be benched through surficial deposits and into competent bedrock or other material deemed suitable by the Soils Engineer. 5. Rock fragments less than six inches in diameter may be utilized in the fill, provided: a) They are not placed in concentrated pockets; b) There is a sufficient percentage of fine-grained material to surround the rocks; c) The distribution of the rocks is supervised by the Soils Engineer. 6. Rocks greater than six inches in diameter should be taken off site, or placed in accordance with the recommendations of the Soils Engineer in areas designated as suitable for rock disposal. 7. In clay soil large chunks or blocks are common; if in excess of six (6) inches minimum dimension then they are considered as oversized. Sheepsfoot compactors or other suitable methods should be used to break the up blocks. 8. The Contractor should be required to obtain a minimum relative compaction of 90 percent out to the finished slope face of fill slopes. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment. If fill slopes are built "at grade" using direct compaction methods then the slope construction should be performed so that a constant gradient is maintained throughout construction. Soil should not be "spilled" over the slope face nor should slopes be "pushed out" to obtain grades. Compaction equipment should compact each lift along the immediate top of slope. Slopes should be back rolled approximately every 4 feet vertically as the slope is built. Density tests should be taken periodically during grading on the flat surface of the fill three to five feet horizontally from the face of the slope. In addition, if a method other than over building and cutting back to the compacted core is to be employed, slope compaction testing during construction should include testing the outer six inches to three feet in the slope face to determine if the required compaction is being achieved. Finish grade testing of the slope should be performed after construction is complete. Each day the Contractor should receive a copy of the Soils Engineer's "Daily Field Engineering Report" which would indicate the results of field density tests that day, 9. Fill over cut slopes should be constructed in the following manner: a) All surficial soils and weathered rock materials should be removed at the cut-fill interface. b) A key at least 1 equipment width wide (see report) and tipped at least 1 foot into slope should be excavated into competent materials and observed by the Soils Engineer or his representative. c) The cut portion of the slope should be constructed prior to fill placement to evaluate if stabilization is necessary, the contractor should be responsible for any additional earthwork created by placing fill prior to cut excavation. 10. Transition lots (cut and fill) and lots above stabilization fills should be capped with a four foot thick compacted fill blanket (or as indicated in the report). 11. Cut pads should be observed by the Geologist to evaluate the need for overexcavation and replacement with fill. This may be necessary to reduce water infiltration into highly fractured bedrock or other permeable zones,and/or due to differing expansive potential of materials beneath a structure. The overexcavation should be at least three feet. Deeper overexcavation may be recommended in some cases. (3) 12. Exploratory backhoe or dozer trenches still remaining after site removal should be excavated and filled with compacted fill if they can be located. Gradina Observation and Testinq 1. 2. 3. 4. 5. 6. Observation of the fill placement should be provided by the Soils Engineer during the progress of grading. In general, density tests would be made at intervals not exceeding two feet of fill height or every 1,000 cubic yards of fill placed. This criteria will vary depending on soil conditions and the size of the fill. In any event, an adequate number of field density tests should be made to evaluate if the required compaction and moisture content is generally being obtained. Density tests may be made on the surface material to receive fill, as required by the Soils Engineer. Cleanouts, processed ground to receive fill, key excavations,subdrains and rock disposal should be observed by the Soils Engineer prior to placing any fill. It will be the Contractor’s responsibility to notify the Soils Engineer when such areas are ready for observation. A Geologist should observe subdrain construction. A Geologist should observe benching prior to and during placement of fill. utilitv Trench Backfill Utility trench backfill should be placed to the following standards: 1. Ninety percent of the laboratory standard if native material is used as backfill. 2. As an alternative, clean sand may be utilized and flooded into place. No specific relative compaction would be required; however, observation, probing, and if deemed necessary, testing may be required. 3. Exterior trenches, paralleling a footing and extending below a 1:l plane projected from the outside bottom edge of the footing, should be compacted to 90 percent of the laboratory standard. Sand backfill, unless it is similar to the inplace fill, should not be allowed in these trench backfill areas. Density testing along with probing should be accomplished to verify the desired results.
