It is our understanding that some additional grading is proposed to develop these sites but the maximum cuts and fills planned are generally in the order of 10 feet or less in height. The site configuration and exploration locations are shown on Plate No. 1. I. PROJECT SCOPE This investigation consisted of: surface reconnaissance; subsurface explorations ; obtaining representative disturbed and undisturbed samples ; laboratory testing; analysi's of the field and laboratory data; research of available geological literature pertaining to the site; and preparation of this report. Spec.ifically, the intent of this analysis was to: a) Explore the subsurface conditions to the depths influenced by the proposed construct i dn . ~ SOUTHERN CALIFORNIA SOIL AND TESTING, INC.

FIND1 NGS SITE DESCRIPTION The project site consists of four lots within an existing subdivision east of the intersection of Bruce Road and Park Drive in Carlsbad, California. Lot 3 is located on a west to east trending ridge with a level pad on the upper eastern portion of the lot which has been cut into the ridge. This site slopes steeply to the northwest, west and southwest with elevations ranging from approximately 50 feet to 90 feet (MSL). These slopes are in a natural condition and vegetation consists of heavy growth of native brush, plants and grasses. Lots 6, 7, and 8 consist of relatively level cut and fill pads bounded,by approximately 4 feet to 30 feet high moderately steep, cut and fill slopes. Fill on these slopes ranges up to 7 feet high with a slope ratio on the order of approximately 2:l (horizontal to vertical). Elevations on these lots rang; from 30 feet to 100 feet (MSL). SCS&T 8521118 June 6, 1985 Page 3 GENERAL GEOLOGY AND SUBSURFACE CONDITIONS GEOLOGIC SETTING AND SOIL DESCRIPTION: The subject site is located in the Coastal Plains Physiographic Province of San Diego County and is underlain by materials of sedimentary origin and some artifical fill. Lot 3 has been cut into the Eocene Santiago Formation and associated topsoil which consists of tan, humid, dense, silty sandstone and up to 1 foot of brown, dry, loose silty sand respectively. Soil conditions as encountered in our explorations on Lots '6, 7 and 8 were approximately 3 to 7 feet of artificial fill consisting of brown to dark gray brown, humid to moist, loose to medium dense silty sand. The fill was generally underlain by a minimum of 4 feet of alluvium which consist of gray brown to dark gray brown, moist, medium dense silty sand. On Lot 8 this alluvium was underlain by a minimum of 2 feet of light tan, moist, medium dense very friable sand. On the lower northwest pad area of Lot 7, three feet of artifical fill was underlain by in excess of 7 feet of dark brown to gray brown alluvium which was moist, medium dense, clayey sand. TECTONIC SETTING: No evidence of faulting was noted during our surface reconnaissance or in our exploratory trenches. A review of available geologic literature reveals the presence of numerous minor northeast trending faults in the Carlsbad vicinity of the site that are presently classified as inactiye. The project site is located approximately 6 miles east of the Rose Canyon Fault Zone. The Rose Canyon Fault Zone is a series of northwest trending faults of Quaternary age that is currently classified as potentially active, rather than active according to the criteria of the California Division of Mines and Geology. This classification is based on the lack of the conclusive evidence to verify Holocene movement along this faul t zone. It should be recognized that much of Southern California is charactirized by major, active fault zones that could possibly affect the subject site. The nearest of these are the Elsinore Fault Zone, located approximately 24 miles to the northeast. , SCSetT 8521118 June 6, 1985 Page 4 GEOLOGIC HAZARDS The subject site can be considered to be relatively free of geologic hazards. Potential hazards such as tusnamis, seiches, liquefaction, or 1 andsl idi ng should be considered to be negl i gi bl e or nonexistent . The most likely major geologic hazard to affect the site is groundshaking as a result of movement'along one of .the major active fault zones mentioned previously. The maximum bedrock accelerations that would be attributed to a maximum probable earthquake occurring along the nearest portion of selected fault zones that could affect the site are summarized in the fol 1 owi ng tab1 e. TABLE 1 Maximum Probable Maximum Bedrock Fault Zone Classification Distance Earthquake Accel era ti on Rose Canyon Potentially 6 miles 6.0 magnitude 0.359 El si nore Active 24 miles 7.3 magnitude 0.239 Active Based on the current fau<lt zone classification, and the maximum bedrock accelerations capable of developing, it is recommended that the Coronado Banks, Elsinore or San Clemente Fault Zones be considered the design earthquake source for the subject development. Although a maximum probable earthquake along the La Nacion and/or Rose Canyon Fault Zones could conceivably produce ground motions considerably stronger than those that would be attributed to the major, active fault zones, it is our opinion that, due to the current classification of these local fault zones as potentially active rather than active, they should not be used as the design earthquake source for this project. SCS&T 8521118 June 6, 1985 Page 5 Construction in accordance with the minimum standards of the Uniform Building Code and the governing agencies should minimize potential damage due to groundshaking. GROUNDWATER: No groundwater was encountered during our subsurface exploration and we do not anticipate any major groundwater related problems, either during or after construction. However, it should be recognized that minor groundwater seepage problems may occur after devel opement of a si te - even where none were present before development . These are usually minor phenomena and are often the result of an alteration of the permeability charcteristics of the soil, an alteration in drainage patterns and an increase in irrigation water. Based on the permeability characteristics of the soil and anticipated usage of the development, it is our opinion that any seepage problems which may occur will be minor in extent. It is further our opinion that these problems can be most effectively corrected on an individual basis if and when they develop. I RECOMMENDATIONS AND CONCLUSIONS SITE PREPARATION GENERAL: We recommend that the existing fill and loose native soils be removed to firm natyral ground and be stockpiled for future use. Firm natural gournd is defined as native soil which possesses an in-situ density equal to or greater 85% of its maximum dry density. The soils exposed at the base of these excavations should then be scarified 12 inches, be moisture treated to at least 2% over optimum and densified to a minimum of 90% relative compaction. The stockpiled soils may then be replaced in eight inch lifts, moisture conditioned and compacted as indicated above. The horizontal limits of these recommendations should include the area within a perimeter of 10 feet outside of each proposed structure and all areas to receive additional fill and all slopes. Based on the findings of this study, it is anticipated that the maximum depth of removal and recompaction will be on the orher of seven feet. SCS&T 8521118 June 6, 1985 Page 6 SURFACE DRAINAGE: We recommend that a1 1 surface drainage be directed away from the proposed structures and that ponding of water not be allowed adjacent to the building foundations. It is further recommended that drainage not be allowed to flow over the top of slopes. EARTHWORK: All earthwork and grading contemplated for site preparation should be accomplished in accordance with the attached Recommended Grading Specifications and Special Provisions. All special site preparation recommendations presented in the sections above will supersede those in the standard Recommended Grading Specifications. All embankments , structural fill and fill should be compacted to at least 90% relative compaction at or slightly over optimum moisture content. Utility trench backfill within five feet of the proposed structures and beneath asphalt pavements should be compacted to a minimum of 90% of its maximum dry density. The maximum dry density of each soil type should be determined in accordance with A.S.T.M. Test Method D-1557-78, Method A or C. FOUNDATIONS I. . GENERAL: It is our opinion that the proposed building may be supported by shallow spread footings. All footings should be founded at least 12 or 18 inches below lowest adjacent finished grade for one or two story structures , respectively. All footings should possess a minimum width of 12 inches. An allowable soil bearing pressure of 2000 psf may be used for foundation design. We further recommend that all continuous footings .be reinforced with at least one No. 4 bar top and bottom. SETTLEMENT CHARACTERISTICS: The anticipated total and/or di fferenti a1 settlements for the proposed structure may be considered to be within tolerable 1 imits provided the recommendations presented in this report are fol 1 owed. EXPANSIVE CHARACTERISTICS: The prevailing foundation soils were found to be nondertimentally expansive and will not require special consideration and/or desi gn. SCS&T 8521118 RETAINING WALLS June 6, 1985 Page 7 GENERAL: It is our understanding that the retaining walls planned for the site will be of masonry construction and that they will have a maximum height on the order of 6 feet. All walls should have adequate weep holes or a subdrain system to prevent a building of hydrostatic pressure behind the wall. BACKFILL: All backfill soils should be compacted to at least 90% relative compaction. Expansive or clayey soils should not be used for backfill material. The wall should not be backfilled until the masonry has reached an adequate.strength. BEARING PRESSURE: The foundation for the proposed walls may consist of spread footings founded in the native soils or compacted fill. Footings should extend through any loose topsoils and fill or the topsoils and fill should be removed and be replaced as a compacted fill. Footings may be designed for an allowable bearing pressure as previously recommended. PASSIVE PRESSURE: The passive pressure for the prevailing soil conditions may be considered to be 350 pounds per square foot per foot of depth. This pressure may be increased one-third for seismic loading. The coefficient of friction for concrete to soil may be assumed to be 0.55 for the resistance to lateral movement. When combining frictional and passive resistance, the latter should be reduced by one-third. ACTIVE PRESSURE: The active soil pressure for the design of earth retaining structures with level backfills may be assumed to be equivalent to the pressure of a fluid weighing 35 pounds per cubic foot for walls free to move at the top (unrestrained walls). For a 2:l backfill condition, this design pressure should be increased to 55 pcf. These pressures do not consider any surcharge other than the sloping backfill. If any are anticipated this office should be contacted for the necessary increase in soil pressure. SCS&T 8521118 June 6, 1985 Page 8 FACTOR OF SAFETY: The above values, with the exception of the allowable soil bearing pressure, do not include a factor of safety. Appropriate factors of safety should be incorporated into the design to prevent the walls from overturning and sliding. L I M I TAT I ONS REVIEW, OBSERVATION AND TESTING The recommendations presented in this report are contingent upon our review of final plans and specifications. The 'soil engineer and engineering geolgist should review and verify the compliance of the final grading plan with this report and with Chapter 70 of the Uniform Building Code. It is recommended that Southern California Soil & Testing, Inc. be retained to provide continuous soil engineering services during the earthwork operations. This is to observe compliance with the design concepts, specifications or recommendations and to allow design changes in the event that subsurface conditions differ from those anticipated prior to start of construction. UNIFORMITY OF CONDITIONS 8, The recommendations and opinions expressed in this report reflect our best estimate of the project requirements based on an evaluation of the subsurface soil conditions encountered at the subsurface exploration locations and the assumption that the soil conditions do not deviate appreciably from those encountered. It should be recognized that the performance of the foundations and/or cut and fill slopes may be influenced by undisclosed or unforseen variations in the soil conditions that may occur in the interm'ediate and unexplored areas. Any unusual conditions not covered in this report that may be encountered during site development should be brought to the atte.ntion of the soils engineer so that he may make modifications if necessary. SCS&T 8521118 June 6, 1985 Page 9 CHANGE IN SCOPE This office should be advised of any changes in the project scope or proposed site grading so that it may be determined if the recommendations contained herein are appropriate. This should be verified in writing or modified by a written addendum. TIME LIMITATIONS The findings of this r'eport are valid as of this date. Changes in the condition of a property can, however, occur with .the passage of time, whether they be due to natural processes or the work of man on this or adjacent properties. In addition, changes in the State-of-the-Art and/or Government Codes may occur. Due to such changes, the findings of this report may be invalidated wholly or in part by changes beyond our control. Therefore, this report should not be relied upon after a period of two years without a review by us verifying the suitability of the conclusions and recommendations.

FIELD EXPLORATIONS Five subsurface explorations were .made at the locations indicated on the attached Plate Number 1 on May 24, 1985. These explorations consisted of trenches dug by means of a backhoe. The field work was conducted under the observation of our geology personnel. The explorations were carefully logged when made. These logs are presented on the following Plate Numbers 3 through 7. The soils are described in accordance with the Unified Soils Classification System as illustrated on the attached simplified chart on Plate 2. In addition, a verbal textural description, the wet color, the apparent moisture and the density or consistency are presented. The density of granular materials is given as either very loose, loose, medium dense, dense or very dense. The consistency of silts or clays are given as either very soft, soft, medium stiff, stiff, very stiff, or hard. Disturbed and "undisturbed" samples of typical and representative soils were obtained and returned to the laboratory for testing. LABORATORY TESTING Laboratory tests were performed in accordance with the generally accepted American Society for Testing and Materials (A.S.T.M.) test methods or suggested procedures. A brjef description of the tests performed is presented bel ow: SCS&T 8521118 June 6, 1985 Page 11 a) MOISTURE-DENSITY: Field moisture content and dry density were determined for representative undisturbed samples obtained. This information was an aid to classification and permitted recognition of variations in material consistency with depth. The dry unit weight is determined in pounds per cubic foot, and the field moisture content is determined as a percentage of the soil's dry weight. The results are summarized in the trench 1 ogs. b) CLASSIFICATION: Field classifications were verified in the laboratory by visual examination. The final soil classifications are in accordance with the Unified Soil C1 as s i f i cat i o n Sys tern. DIRECT SHEAR TESTS: Direct shear tests were performed to determine the failure envelope based on yield shear strength. The shear box was designed to accomodate a sample having diameters of 2.375 inches or 2.50 inches and a height of 1.0 inch. Samples were tested at different vertical loads and a saturated moisture content. The shear stress was applied at a constant rate of strain of approximately 0.05 inches per minute. The results of these tests are presented on attached Plate Number 8 ., d) COMPACTION TEST: The maximum dry density and optimum moisture content of typical soils were determined in the laboratory in accordance with A.S.T.M. Standard Test 0-1557-78, Method A. The results of these tests are presented on the attached Plate No. 8.

The recommendations contained in the preliminary soil investigation report and/or the attached Special Provisions are a part of the Recommended Grading Specifications and shall supersede the provisions contained hereinafter in the case of conflict. These specifications shall only be used in conjunction with the soil report for which they are a part. No deviation from these specifications will be allowed, except where specified in the soil report or in other written communication signed by the Soil Engineer . OBSERVATION AND TESTING Southern California Soil and Testing, Inc., shall be retained as the Soil Engineer to observe and test the earthwork in accordance with these specifications. 1.t will be necessary that the Soil Engineer or his representative provide adequate observation so that he may provide an opinion that the work was or was not accomplished as specified. It shall be the responsibility of the contractor to assist the soil engineer and to keep him apprised of work schedules, changes and new information and data so that he may provide these opinions, In the event that any unusual conditions not covered by the special provisions or preliminary soil report are encountered during the grading operations, the Soil Engineer shall be contacted for further recommendations. .a SCS&T 8521118 June 6, 1985 Appendix, Page 2 If, in the opinion of the Soil Engineer, substandard conditions are encountered, such as; questionable or unsuitable soil, unacceptable moisture content, inadequate compaction, adverse weather, etc., he will be empowered to either to either stop construction until the conditions are remedied or corrected or recommend rejection of this work. Test methods used to determine the degree of compaction should be performed in accordance with the following American Society for Testing and Materials test methods: Maximum Density & Optimum Moisture Content - A.S.T.M. D-1557-78. Density of Soil In-Place - A.S.T.M. D-1556-64 or A.S.T.M. D-2922. All densities shall be expressed in terms of Relative Compaction as determined by the foregoing A.S.T.M. testing procedures. PREPARATION OF AREAS TO RECEIVE FILL A1 1 vegetation, brush and debris derived from clearing operations shall be removed, and legally disposed of. all areas disturbed by site grading should be left in a neat and finished appearance, free from unsi ghtl y debris . Any abandoned buried structures encountered during grading operations must be totally removed. All underground utilities to be abandoned beneath any proposed structure should be.removed from within 10 feet of the structure and properly capped off. The resulting depressions from the above described procedures should be backfilled with acceptable soil that is compacted to the requirements of the Soil Engineer. This includes, but is not limited to, septic tanks, fuel tanks, sewer lines or leach lines, storm . ..I SCS&T 8521118 June 6, 1985 Appendix, Page 3 drains and water lines. Any buried structures or utilities not to be abandoned should be investigation by the Soil Engineer to determine if any special recoininendation will be necessary. All water wells which will be abandoned should be backfilled and capped in accordance to the requirements set forth in the Geotechnical Report. The top of the cap should be at least 4 feet below finish grade or 3 feet below the bottom of footing w-hichever is greater. The type of cap will depend on the diameter of the well and should be determined by the Soil Engineer and/or a qualified Structural Engineer. When the slope of the natural ground receiving fill exceeds 20% (5 horizontal units to 1 vertical unit), the original ground shall be stepped or benched. Benches shall be cut to a firm competent soil condition. The lower bench shall be at least 10 feet wide or 1 1/2 times the the equipment width which ever is greater and shall be sloped back into the hillside at a gradient of not less than two (2) percent. All other benches should be at least 6 feet wide. The horizontal portion of each bench shall be compacted prior to receiving fill as specified hereinbefore for compacted natural ground. Ground slopes flatter than 20% shall be benched when considered necessary by the Soil Engineer. I After clearing or benching, the natural ground in areas to be filled shall be scarified to a depth of 6 inches, brought to the proper moisture content, compacted and tested for the minimum degree of compaction in the Special Provisions or. the recommendation contained in the preliminary soil investigation report. All loose soils in excess of 6 inches thick should be removed to firm natural ground which is defined as natural soils which possesses an in-situ density of at least 85% of its maximum dry density. SCS&T 8521118 June 6, 1985 Appendix, Page 4 FILL MATERIAL Materials placed in the fill shall be approved by the soil engineer and shall be free of vegetable matter and other deleterious substances. Granular soil shall contain sufficient fine material to fill the voids. The definition and disposition of oversized rocks, expansive and/or detrimental soils are covered in the soils report or Special Provisions. Expansive soils, soils of poor gradation, or soils with low strength characteristics may be thoroughly mixed with other soils to provide satisfactory fill material, but only with the explicit consent of the soil engineer. Any import material shall be approved by the Soil Engineer before being brought to the site. PLACING AND COMPACTION OF FILL Approved fill material shall be placed in areas prepared to receive fill in layers not to exceed 6 inches in compacted thickness. Each layer shall have a uniform moisture content in the range that will allow the compaction effort to be efficiently applied to achieve the specified degree of compaction. Each layer shall be uniformly compacted to a minimum specified degree of compaction with equipment of adequate size to economically compact the layer. Compaction equipment should either be specifically designed for soil compaction or of proven reliability. The minimum degree of compaction to be achieved is specified in either the Special Provisions or the recommendations contained in the preliminary soil investigation report. When the structural fill material includes rocks, no rocks will be allowed to nest and all voids must be carefully filled with soil such that the minimum degree of compaction recommended in the Special Provisions is c -. SCS&T 8521118 June 6, 1985 Appendix, Page 5 achieved. The maximum size and spacing of rock permitted in structural fills and in non-structural fills is discussed in the soil report, when appl i cab1 e. Field observation and compaction tests to estimate the degree of compaction of the fill will be taken by the Soil Engineer or his representative. The location and frequency of the tests shall be at the Soil Engineer's discretion. When the compaction test indicates that a particular layer is less than ,the required degree of compaction, the layer shall be reworked to the satisfaction of the Soil Engineer and until the desired relative compaction has been obtained. Fill slopes shall be compacted by means of sheepsfoot rollers or other sui tab1 e equipment. compaction by sheepsfoot rol lers shall be at vertical intervals of not greater than four feet. In addition, fill slopes at ratios of two horizontal to one vertical or flatter, should be trackrolled. Steeper fill slopes shall be over-buil t and cut-back to finish contours. Slope compaction operations shall result in all fill material six or more inches inward from the finished face of the slope having a relative compaction of at least 90% of maximum dry density or that specified in the Special Provisions section of this specification. The compaction operation on the slopes shall be continued until the Soil Engineer is satisfied that the slopes will be skable in regards to surficial stability. Slope tests will be made by the Soils Engineer during construction of the slopes to determine if the required compaction is being achieved. Where failing tests occur or other field problems arise, the Contractor will be notified that day of such conditions by written communication from the Soil Engineer in the form of a daily field report. , .I. SCSPtT 8521118 June 6, 1985 Appendix, Page 6 If the method of achieving the required slope compaction selected by the Contractor fail s to pro’duce the necessary rcsul ts, the Contractor shall rework or rebuild such slopes until the required degree of compaction is obtained, at no additional cost to the Owner or Soils Engineer. CUT SLOPES The Engineering Geologist shall inspect all cut slopes excavated in rock or 1 ithified formational material during the grading operations at intervals determined at his discretion. If any conditions not anticipated in the preliminary report such as perched water, seepage, lenticular or confined strata of a potentially adverse nature, unfavorably inclined bedding, joints or fault planes are encountered during grading, these conditions shall be analyzed by the Engineering Geologist and Soil Engineer to determine if mitigating measures and necessary Unless otherwise specified in the soil and geo shall be excavated higher or steeper than that the controlling governmental agency. ogical report, no cut slopes allowed by the ordinances of 1 ENGINEERING OBSERVATION Field observation by the soil Engineer or his representative shall be made during the filling and compacting operations so that he can express his opinion regarding the conformance of the grading with acceptable standards of practice. The presence of the Soil Engineer or his representative or the observation and testing shall not release the Grading Contractor from his duty to compact all fill material to the specified degree of compaction. C , SCS&T 8521118 June 6, 1985 Appendix, Page 7 SEASON LIMITS Fill shall not be placed during unfavorable weather conditions. When work is interrupted by heavy rain, filling operations shall not be resumed until the proper moisture content and density of the fill materials can be achieved. Damage site conditions resulting from weather or acts of God shall b repaired before acceptance of work. RECOMMENDED GRADING SPECIFICATIONS - SPECIAL PROVISIONS The minimum degree of compaction to be obtained in compacting natural ground, in the compacted fill, and in the compacted backfill shall be at least 90 percent. Detrimentally expansive soil is defined as soil which will swell more than 3 percent against a pressure of 150 pounds per square foot from a condition of 90 percent of maximum dry density and air dried moisture content to saturation. I Oversized fill material is defined as rocks or lumps over 6 inches in diameter. At least 40 percent of the fill soils shall pass through a No. 4 U.S. Standard Sieve. TRANSITION LOTS: Where transitions between cut and fill occur within the proposed building pad, the cut portion should be undercut a minimum of one foot below the base of the proposed footings and recompacted as structural backfill. ~CARLSBAD UNIFIED SCHOOL DISTRICT RECEIPT NO. c] CARLSBAD HIGH SCHOOL FOR $32 {bo \I\\ \?a\, (~na \>s\ BQOC~ hi.
