REPORT OF FOUNDATION EXCAVATION INSPECTION PARCELS 1, 2, and 3, PARCEL MAP NO. 11391. Gentlemen: At the request of Mr. Thomas D. Elliott we have observed the removal of uncompacted fill and colluvium at the subject site, and observed and tested the fills placed on the property earlier this month. Our final report of May 11, 1983 indicates that the grading was done in accordance with the recommendations made by Geocon, Incorporated in their Soil Investigation report dated September 21, 1981, and that the tests indicate that the fills have been compacted to 90 percent or more of the maximum laboratory density. In addition we have inspected the footing'excavations for the 3 residences and it is our opinion that the excavations have been made in conformance with the plans for the project with respect to depth and width. Groundwater was encountered by Geocon at a depth of approximately 9 feet below the previously existing ground surface. We don't believe that the presence of water at that depth will adversely affect the performance of the foundations for these residences. The soil within 3 feet of rough grade has been inspected and tested and is determined to be non-expansive. Therefore it is our opinion that no special precautions are necessary to compensate for the expansive characteristics of the finish grade soils.

Elliott 2445 Garfield Street Carlsbad, California 92008 FINAL REPORT OF ENGINEERING OBSERVATION OF GRADING AND TESTING OF COMPACTED FILL, PARCELS 1, 2, AND 3, PARCEL MAP NO. 11391. Dear Mr. Elliott: In accordance with your request, we have provided observati6n and testing services in conjunction with the grading of the subject site. SCOPE OF WORK Our services included: 1) Periodic engineering observation of the grading operation, 2) Periodic observation of the excavation and removal of colluvium and uncompacted fill in the areas noted in the Soil Investigation report by Geocon, Incorporated, dated September 21, 1981. 3) Periodic observation of the general preparation of areas to receive fill. 4) Taking field density tests in the placed and compacted fill. 5) Performing laboratory tests on representative samples of the materials used for fill. SDS 7173 May 11, 1983 Page 2 SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation, compaction, and testing were done between May 3 and May 10, 1983. It is our opinion, based on our observation and testing, that the work performed during that period was in general conformance with the recommendations made by Geocon, Incorporated,Soil Investigation and Geologic Reconnaissance report dated September 21, 1981. Fill was placed, compacted and tested on three parcels and driveway as shown on attached site plan. The grading operation essentially consisted of the preparation of the area to receive fill, including excavation of loose fill, colluvium, and surficial soils, scarifying and compacting surfaces to receive fill, and making cuts and fills to design grades. As the site grading progressed, compaction procedures were observed and field density tests were made to evaluate the - relative compaction of the fill in place. Field observations and field density test results indicate that the fills have been compacted to 90 percent or more of the maximum laboratory density. For reference, the approximate location of field density tests and the limits of compacted fill have been recorded on the attached site plan. The results of field density tests, expressed as a percentage of the maximum laboratory density, are given on the attached forms. Laboratory tests to evaluate moisture-density relationships, maximum dry density and optimum moisture content and swell characteristics were performed on representative samples of the materials used for fill. The results of the laboratory tests are attached. Compactions tests shown as finish grade (FG) tests correspond to the elevations shown on the grading plan, prepared by Patrick O'Day, SDS 7173 ,May 11, 1983 Page 3 Oceanside, California, except that the upper pad on parcel 3 was lowered from 107.6 to approximately 102.6. Elevations and locations given in this report are based on field surveys established by others. SUMMARY OF FINISH GRADE SOIL CONDITIONS Laboratory tests and inspection indicates that soils within 3 feet of rough grade are of low expansive potential. RECOMMENDATIONS Foundation recommendations for this site were made by Geocon, Incorporated in their report dated September 21, 1981. Slopes Newly constructed fill slopes are approximately 2 to 1 (horizontal to vertical) and approximately 4 feet maximum in height. Newly constructed fill slopes were backrolled with a sheepsfoot compactor, and trimmed with a slope blade. We recommend that structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) not be located within 5 feet of the top of the slope. Footings located closer than 5 feet from the top of a slope should be extended in depth until^ the outer bottom edge of the footing is 5 feet horizontally from the outside face of the slope. Exterior Slabs Exterior slabs should be not less than 4 inches in thickness. Walks or slabs 5 feet or less in width need not be reinforced. Those exceeding 5 feet in width should be reinforced with 6" x 6" 10/10 welded wire mesh positioned at the center of the slab cross-section. Weakened plane joints consisting of grooves 1/8" to 1/4" wide and 1 1/4" deep should be provided for all exterior slabs as recommended in the figure below. SDS 7173 May 11, 1983 Page 4 Additional Fill and Utility Trenches This report discusses the fill placed under our observation and during the dates specified herein. We recommend that any additional fill placed after these dates, as well as the back- fill in utility trenches located within 5 feet of a building and greater than 12 inches deep, or in any trench 5 feet or more from a building and in excess of 5 feet in depth be compacted under the observation of this office and tested to assure compaction to not less than 90 percent of the maximum laboratory density. This office should be contacted at least 24 hours prior to the backfilling operations. Drainage We recommend that positive measures be taken to properly finish grade these parcels after the structures and other improvements are in place, so that drainage waters from the parcels and adjacent properties are directed off tlie parcels and away from building foundations, floor slabs, and top of slopes. Even with these provisions, experience has shown that a shallow or surface ground water condition can and may develop in areas where no such condition existed prior to development; this is particularly true in developments where a substantial increase in surface water infiltration results from landscape irrigation. SDS 7173 May 11, 1983 Page 5 LIMITATIONS The inspections of fill foundation preparation, types of materials, and soil placement and compaction made during the period of our services on the subject site, were in accordance with local acceptable standards at this time. The conclusions or opinions drawn from the tests and site inspections apply to our work with respect to grading, and represent conditions at the date of our final inspection. We will accept no responsibility for any subsequent changes made to this site by others, or by uncontrolled action of water, or by failure of others to properly repair damage caused by uncon- trolled action of water. If you have any questions regarding this letter, please do not hesitate to contact, us. Sincerely, SAN DIEGUITO SOILS, INC., BY BILL K. BRAMBLE, RCE 8102 BKB/LC/tlk SAN DIEGUITO SOILS, INC.

APPENDIX A LABORATORY TESTS The materials observed during construction were evaluated with respect to expansive potential, dry density, moisture content, and compaction characteristics. 1) Maximum :dry density tests were performed on represen- tative samples returned to the laboratory. The purpose of these tests was to provide a basis of comparison for compacted fill conditions to County Grading Ordinance Standards. The results of the tests performed in accordance with A.S.T.M. Test Method D-1557-78, are as follows: Sample Number 1 2 Maximum Dry Density (pcf) 119.7 131.7 Optimum Moisture (%•) 12.4 9.3 2) Expansion Potential The Expansion Potential of representative recompacted samples of soil was determined by allowing the samples to swell against a surcharge of 150 psf when brought into contact with water.

September 21, 1981 SOIL INVESTIGATION AND GEOLOGIC RECONNAISSANCE Purpose and Scope The purpose of this soil investigation and geologic reconnaissance was to observe and sample the prevailing soil conditions at the site, to evaluate possible geologic hazards to the site and to provide recommendations for foundation design and other geotechnical aspects of site development. The investigation was performed on July 15, 1981 and consisted of a site reconnaissance : by our staff geologist and the drilling of three small- diameter exploratory borings. In addition, available geologic literature was reviewed to evaluate the presence of previously mapped geologic hazards such a faults or ancient landslides which may exist in the vicinity of the site. Laboratory tests were performed on soil samples from the site to determine various physical properties of the soil types encountered. The conclusions and recommenations presented herein are based on engineering analysis of the results of our field investigation and laboratory tests. Site and Project Description The 1.1 acre, L-shaped site is located on the south side of Chestnut Avenue, east of Highland Drive in Carlsbad, California. The southern end -1- GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981 of the site slopes gently down to the east, while the northern portion of the site has been filled to a relatively flat-lying configuration. An elevation differential of approximately 18 feet exists between the highest point of the site, which is located near the southwest property corner, and the lowest portion of the site, along the east property line. Vegetation consists of moderate to light growths of native weeds and grasses and scattered trees. Based on the "Grading Plan, Parcels 1, 2 and 3 of P.M. 11391" prepared by O'Day Consultants and dated 3une 15, 1981, the site will be graded to level building pads with proposed 2:1 and 3:1 cut and fill slopes less than 10 feet high. It is our understanding that each of the three parcels will receive a wood-frame single-family residence and that foundation loads will be rela- tively light. Field Investigation The field portion of the investigation was performed on July 15, 1981 and consisted of a site reconnaissance by our staff geologist and the drilling of three six-inch-diameter borings, 10 to 11 feet in depth. -2- GEOCON INCORPORATED File No. D-2579-TO1 September. 21, 1981 The borings were drilled by means of a truck-mounted rotary drill rig equipped with six-inch-diameter continous flight auger. As drilling pro- ceeded, relatively undisturbed soil samples were obtained at various depths by driving a three-inch O.D. split-tube sampler into the undisturbed soil mass with blows from a 140-pound hammer falling 30 inches. The sampler was internally equipped with one-inch-high by two and three-eighths-inch- diameter brass sampler rings to facilitate sample removal and testing. Dis- turbed bulk samples were also obtained. The approximate locations of the borings are shown on the attached Site Plan, Figure 1. Logs of the test borings are presented on Figures 2 and 3 of Appendix A. The logs depict the depth and description of the various soil types encountered and include the depths at which samples were obtained. Laboratory Tests Laboratory tests were performed in accordance with generally accepted test methods of the American Society for Testing and Material (ASTM) and other suggested procedures. Selected relatively undisturbed drive samples were tested for their in-place dry density, moisture content, shear strength and expansive potential. -3- GEOCON INCORPORATED File No. D-2579-T01 September 21, 1981 CHESTNUT AVENUE SCALE /'" Bl iV\^i Qt a FUTURE PROPERTY LINE FOR STREET LEGEND Oof.

The results of our laboratory tests are summarized in tabular form in Appendix A. Moisture-density results are also presented on the Logs of Test Borings. Soil and Geologic Conditions Four general soil types were encountered in our borings: uncompacted fill, topsoils, colluvium and Quaternary Marine Terrace Deposits. Each of the soil types encountered is discussed below. Uncompacted Fill. A significant amount of uncompacted, end- dumped fill is present over the northern portion of the site (see Figure 1). The depth of fill encountered in Boring 3 was approximately four feet, however, the fill depth probably increases toward the eastern portion of the fill which was inaccessible to our drill rig. We estimate fill depths to be on the order of six to eight feet in that area. The fill material is charac- terized by loose, silty and clayey sands with scattered asphalt and concrete chunks. It will be necessary to remove and recompact the existing fill soils during grading operations. -5- GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981. Topsoil. The majority of the site is overlain by a one- to two-foot- thick layer of topsoil which consists of medium loose to loose silty sands. Recompaction of the topsoils will be necessary in areas to be graded. Colluvium. Loose colluvial material consisting of very moist, silty sand was encountered in Boring 2 to a depth of approximately seven feet. The approximate areal extent of the colluvium is delineated on Figure 1. Some removal and recompaction of the colluvial material will be necessary .if fill is to be placed in the affected area. Marine Terrace Deposits. The Terrace Deposits encountered in our borings are characterized by dense, silty and clayey sand. A layer of sandy clay was encountered at a depth of approximately nine and one-half feet in Boring 2, however, we do not expect the clay to present a significant hazard to site development since it is well below the elevation of anti- cipated grading operations. Geologic Hazards No active faults or ancient landslides are known to exist at or in the imme- diate vicinity of the site and none were encountered in the course of our investigation. The nearest known active faults are the Elsinore Fault and -6- GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981 the San Jacinto Fault which lie approximately 23 and 46 miles, respec- tively, to the northeast. In addition, the mapped offshore trace of the potentially active Rose Canyon Fault Zone (Map No. 1, California Division of Mines and Geology) lies approximately five miles southwest of the site. It is our opinion that the site could be subjected to moderate to severe ground shaking in the event of a major earthquake along any of the above mentioned faults, however, the seismic risk at the site is not significantly greater than that of the immediately surrounding developments. Ground water Groundwater was encountered in Boring 2 near the southeast corner of the property and at a depth of approximately nine and one-half feet below the existing ground surface. We do'not anticipate the groundwater to present a significant hazard to the site due to its depth below expected development elevations. Although no groundwater was encountered at higher elevations of the site, it is possible that some seepage may occur in cut slopes along the western side of the property. If seepage is encountered during grading, we should be notified so that corrective measures can be determined and implemented at that time. GEOCON 'INCORPORATED File No. D-2579-T01 September 21, 1981 CONCLUSIONS AND RECOMMENDATIONS General 1. It is our opinion that the site is suitable for the proposed residential development provided the recommendations of this report are carefully followed. 2. It will be necessary to remove and recompact all existing fill at the site during grading operations. In addition, removal and recompacted of some of the loose colluvial soils near the southeast portion of the site will like- wise be necessary. Grading 3. All grading should be performed in accordance with the Grading Ordinance of the City of Carlsbad and the "Recommended Grading Specifi- cations" presented in Appendix B. Where the recommendations of this section of the report conflict with those of Appendix B, this section of the report takes precedence. *f. Site preparation should begin with the removal and exportation of all debris and vegetation designated for removal. -8- GEOCON I N C Q R P O B A.T E D File No. D-2579-TO1 September21, 1981 5. All existing fill should be removed until firm natural soils are exposed. A representative of this office should observe the overexcavated area to verify that the required depth has been attained. In addition, the area of loose colluvium delineated on Figure 1 should be overexcavated to a depth of at least two feet below the existing ground surface in areas where no structures are planned. Wherever structures will be constructed, the colluvium should be removed to a depth of at least five feet below the existing ground surface for a distance of 10 feet beyond the perimeter of the proposed structure. It is our understanding that a cul-de-sac will be constructed as part of a new public street at the southeast corner of the site. The proposed cul-de-sac extends onto the subject property (see Figure 1) and is underlain by colluvium. The colluvial soils underlying the proposed cul-de-sac should be removed to a depth of two feet prior to the placement of new fill. After the loose materials have been removed, the bottom .of the excavations should be scarified to a depth of 12 inches, moisture conditioned to near optimum moisture content and recompacted to at least 90 percent of maximum dry density. 6. Loose topsoils J present in areas to be filled should be removed and recompacted to at least 90 percent relative compaction. -9- GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981 7. Foundations founded partially on cut and partially in fill soils are not recommended due to the tendency of cut and fill soils to compress or consolidate differently. Where such a condition occurs, it is recommended that the cut portion of the building area be undercut a depth of at least one foot below the bottom of proposed footings and replaced with properly compacted, nondetrimentally expansive fill soils. 8. All fill and backfill should be compacted to at least 90 percent of maxi- mum dry density as determined by ASTM Test Procedure D1557-70, Method A or C. Foundations 9. For one- or two-story residential structures, conventional spread foot- ings are recommended. Such footings should be at least 12 inches wide and should extend at least 12 inches below lowest adjacent pad grade into dense formational soils or properly compacted fill. Excavations for the founda- tions should be observed by a representative of this office prior to the placement of concrete forms and reinforcing steel. -10- GEOCON INCORPORATED . ;-,:;.

We recommend minimum footing reinforcement to consist of two continuous No. ^ steel reinforcing bars placed horizontally in the footings, one near the top and one near the bottom. This recommendation is based on soil support characteristics and is not intended to be in lieu of steel necessary for structural considerations. 11. The allowable bearing capacity for foundations constructed as recom- mended above is 2,000 psf. This value is for dead plus live loads and may be increased by one-third when considering transient loads due to wind or seismic forces. 12. The above foundation recommendations assume that potentially expan- sive soils will not be present within 2.5 feet of finished pad grade. Concrete Slabs-on-Grade 13. Concrete slabs-on-grade should be underlain by dense, natural soils or properly compacted fill. Slabs should have a minimum nominal thickness of four inches and should be underlain by two inches of clean sand. Where •t moisture sensitive floor coverings are anticipated, a visqueen moisture barrier should be provided. GEOOON I N C O R P O R_A T B D File No. D-2579-TO1 September 21, 1981 1*.' Slab reinforcement should consist of 6x6-10/10 welded wire mesh throughout. Care should be taken during the placement of concrete slabs to ensure that the mesh is not forced to the bottom of the slab. Slope Stability 15. Cut and fill slopes constructed of onsite materials should be stable with respect to deep-seated failure to heights of at least 15 feet if con- structed at slope ratios of two horizontal to one vertical, or flatter. Our analysis is based on a factor of safety of 1.5 under static conditions. Drainage 16. Adequate site drainage provisions are imperative. Under no circum- stances should water be allowed to pond adjacent to footings. The site should be fine-graded such that irrigation excess and storm runoff drain away from structures and into swales or other controlled drainages. 17. If ground water seeps are exposed during grading, the project soil engi- neer or engineering geologist should be notified so that appropriate mea- sures may be provided. GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981 « LIMITATIONS, AND UNIFORMITY OF CONDITIONS : 1. The recommendations of this report pertain only to the site investigated and are based upon the assumption that the soil conditions do not deviate from those disclosed in the borings. If any variations or undesirable condi- tions are encountered during construction, or if the proposed construction will differ from that planned at the present time, Geocon, Incorporated should be notified so that supplemental recommendations can be given. 2. This report is issued with the understanding that it is the responsibility of the owner, or of his representative, to ensure that the information and recommendations contained herein are brought to the attention of the architect and engineer for the project and incorporated into the plans, and that the necessary steps are taken to see that the contractor and subcon- tractors carry out such recommendations in the field. 3. The findings of this report are valid as of the present date. However, changes in the conditions of a property can occur with the passage of time, whether they be due to natural processes or the works of man on this or adjacent properties.

PROPERTY Carlsbad, California 1. 1.1 1.2 1.3 2. 3. 3.1 General Description These specifications have been prepared for grading and site development of the P.3.P. Property located on Chestnut Avenue in Carlsbad, California. Geocon, Incorporated, hereinafter described as the soil engineer, should be consulted prior to any site work connected with site development to ensure compliance with these specifications. These specifications shall only be used in conjunction with the soil report of which they are a part. This item consists of clearing and grubbing, preparation of land to be filled, filling of the land, spreading, compaction and control of the fill, and any subsidiary work necessary to complete the grading of the filled areas to conform with the lines, grades and slopes as shown on the accepted plans. The soil engineer will test and observe all grading operations. In the event that any unusual conditions not covered by the special provisions are encountered during the grading operations, the soil engineer should be contacted for further information. Tests The standard test used to define maximum density of the fill soil will be the ASTM Test Procedure D1557-78,Method A or C. All densities will be expressed as a relative compaction in terms of the maximum density obtained in the laboratory by the foregoing standard procedure, v Clearing, Grubbing, and Preparing Areas to be Filled Any trees not utilized in landscaping, structures, weeds, and other rubbish shall be removed, piled, or otherwise disposed of so as to leave the areas that have been disturbed with a neat and finished appearance, free from unsightly debris. v.-.v.s;•'•:--. ••'r^'- ty:?.:•.'(.&"•'•• B-I GEOCON INCORPORATED File No. D-2579-TO1 September 21, 1981 3.2 Septic tanks, if encountered, and debris must be removed from the site prior to any building, grading or fill operations. Septic . tanks, including all connecting drain fields and other lines, should be totally removed and the resulting depressions properly backfilled and compacted. 3.3 Water wells on the site should be capped according to the require- ments of the San Diego County Health Department. The strength of the cap should be at least equal to the adjacent soil. The final elevation of the top of the well casing should be at least three feet below adjacent grade prior to grading of fill operations. 3A Buried tanks, if encountered, should be removed and the resulting depressions properly backfilled and compacted. 3.5 Vegetable matter and soil designated as unsuitable by the soil engineer should be removed under the direction of .the soil engineer. The then exposed surface shall then be plowed or scarified to a depth of at least eight inches and until the surface is free from ruts, hummocks, or other uneven features which would tend to prevent uniform compaction by the equipment to be used. 3.6 The original ground upon which the fill is to be placed should be plowed or scarified deeply, and where the slope ratio of the original ground is steeper than 6.0 horizontal to 1.0 vertical, the bank should be stepped or benched. At the toes of the major fills and on the sideslope fills, the base key should be, as described elsewhere in this report, at least 10 feet in width, cut at least three feet into the undisturbed or native soil, and sloped back into the hillside at a gradient of not less than two percent. Subsequent keys should be cut into the hillside as the fill is brought up the slope. The construction of subsequent keying operations should be determined by the soil engineer during grading operations. In general, the depth of the initial bench key, as well as subsequent keys, should be such that topsoils are removed and keying occurs within the underlying formational soils. Ground slopes which are flatter than 6 to 1 should be benched when considered necessary by the soil engineer. 3.7 After the foundation for the fill has been cleared, plowed, or scarified, it should be disced or bladed until it is uniform and free from large clods; brought to the proper moisture content by adding water or aerating; and compacted to a relative compaction of not less than 90 percent. B-2 GEOCON INCORPORATED File No. D-2579-T01 September 21, 1981 Materials 4.1 Native soil, free of organic material and undesirable deleterious material, may be used as fill. Native soil which is expansive should not be placed on the top two feet of building pads without the approval of the soil engineer. 4.2 The materials for fill should be approved by the soil engineer before commencement of grading operations. Any imported material must be approved for use before being brought to the site. The materials used should be free from vegetable matter and other deleterious material, and be nonexpansive. Expansive soil is defined as soil which expands more than three percent when saturated at 90 percent relative compaction and optimum, moisture content under a surcharge of 150 psf. 5. Placing, Spreading, and Compacting Fill Material 5.1 Fill material should be placed in layers which, when compacted, would permit adequate bonding and compaction. Each layer shall be spread evenly and shall be thoroughly blade mixed during the spreading to provide uniformity of materials in each layer. 5.2 When the moisture content of the fill material is below that specified by the soil engineer, water should be added until the moisture content is as specified. When the moisture content of the fill material is above that specified by the soil engineer, the fill material shall be aerated by blading or other satisfactory methods until the moisture content is as specified. 5.3 After each layer has been placed, mixed, and spread evenly, it should be thoroughly compacted to a relative compaction of not less than 90 percent. 5.4 When fill material includes rock, no rocks should be allowed to "nest", and all voids should be filled and properly compacted. No rocks larger than six inches in diameter should be permitted in the fill except as specified under Section 6.1 "Disposal of Over- sized Rock". 5.5 Compaction should be by sheepsfoot rollers, multiple-wheel pneumatic-tired rollers, or other types of acceptable compacting rollers. Rollers should be of such design that they will be able to compact the fill to the specified moisture content range. Rolling of each layer should be continuous over its entire area and until the required density has been achieved. INCORPORATED File No. D-2579-TO1 September 21, 1981: 5.6 Field density tests shall be made by the soil engineer. Where sheepsfoot rollers are used, the soil may be disturbed to a depth •"^ '•'.',.- of several inches. Density tests should be taken in compacted material below the disturbed surface. When these tests indicate that the density of any layer of fill, or portion thereof, is below the required 90 percent relative compaction, the particular layer, or portion thereof, should be reworked until the required relative compaction has been obtained. 5.7 The fill operation shall be continued in compacted layers, as specified above, until the fill has been brought to the finished slopes and grades as shown on the accepted plans. 5.8 Fill slopes should be compacted by "means of sheepsfoot rollers, "track walking", or other suitable equipment. Compaction operations should be continued until the slopes are properly com- pacted (i.e., field density tests indicate a relative compaction of at least 90 percent at a horizontal distance of two feet from the slope face). 5.9 Earthmoving and working operations should be controlled to prevent water from running into excavated areas. Any water should be promptly removed and the site kept dry. 6. Disposal of Oversized Rock 6.1 Oversized rock should be either exported from the site, used for landscaping purposes, or placed in designated fill areas described in this report or as approved by the soil engineer and/or appro- priate governing agency. 6.2 Oversized rock should not exceed four feet in greatest dimen- sion, should be placed in lifts not exceeding four feet in thickness, and should be placed in a manner that will not produce "nesting" of the rock. The voids between the rocks should be completely filled with fine granular material. 7.
