Mr. Cecil Smith do Mr. Ken Wasmann 16721 Newland Street Huntington Beach, California FINAL REPORT OF ENGINEERING OBSERVATION OF GRADING AND TESTING OF COMPACTED FILL LOTS 2 THROUGH 7 AND 9 THROUGH 16 CARLSBAD TRACT 81-5 CARLSBAD, CALIFORNIA Gentlemen: In accordance with your request, we have provided engineering services in conjunction with the grading of the subject site. SCOPE OF WORK Our services included: Providing engineering observation of the grading operation O Performing field density tests in the placed and compacted fill Performing laboratory tests on representative samples of the material used for fill O Providing professional opinions regarding the contractor's general adherence to plans and specifications SUMMARY OF GENERAL EARTHWORK AND TESTING Site preparation, compaction, and testing were done between April 19 and August 29, 1984. Testing of utility trench continued until November 23, 1984. In our opinion, based on our observation and testing, the work performed during that period was in general conformance with the attached Guide Specifications for Controlled Fill. During the grading period, fill was placed, compacted and tested on Lots 2 through 7 and 9 through 13. Lots 14, 15 and 16 are cut and fill lots. Lots 1 and 8 were reported on June 14, 1984. Prior to placing fill, loose surface Consulting Engineers. Geologists and Environmental Scientists Offices in Other Principal Cities 'r. Mr. Cecil Smith WoI,vard.Clyde Consultants Project No. 54167J-FC01 December 13, 1984 Page 2 soils were excavated approximately 3 feet in depth. The areas to receive fill were then scarified, watered and compacted. Cuts and fills were then made to design grade. Utility trench backfill was observed and tested and fill placed in streets areas was tested. During the grading operation, compaction procedures were observed, and field density tests were made to help evaluate the relative compaction of the placed fill. Field observations and results of field density tests indicate that the fill has been generally compacted to 90 percent or more of maximum dry laboratory density as determined in accordance with ASTM Test method No. D1557-78. For reference, the approximate location of field density tests and the limits of compacted fill have been recorded on a copy of the grading plan. The results of field density tests, expressed as a percent of maximum laboratory dry density (relative compaction), are given on the attached forms. Laboratory tests were made on representative samples of the materials used for fill. The tests were performed to evaluate moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, and plasticity. The results of laboratory tests are attached. SUMMARY OF FINISH GRADE SOIL CONDITIONS Fill Lot and Fill Portion of Cut-Fill Lots Observation and laboratory tests indicate that nonexpansive fill was placed within 3 feet of rough grade on the fill and cut fill lots noted herein. Cut Lots and Cut Portions of Cut-Fill Lots Not Undercut The Cut-portions of Lots 14 and 15 and Lot 16 were observed at the completion of grading. The observation indicated that no expansive soil is evident at rough grade surface. In the preliminary report prepared by Medall Aragon and Warswick, dated September 11, 1981 it is recommended to undercut the cut areas of the lots 3 feet and recompact the soil as controlled fill. This recommendation applies to Lots 14, 15 and 16. In recent communication with Medall Aragon and Warswick we were not able to determine the basis for this recommendation. We assumed, since maximum depth of fill in these lots is relatively small (less than 5 feet), that differential settlement between cut and fill is not the reason. We can only deduce that the reason was - to remove and recompact loose/porous surface soils. Observations during grading indicate that these soils were removed and recompacted from fill and daylight areas (shallow cut and fill zones). Specific locations and types of structures are not known at this time. We should be contacted when this information is available such that we can present additional earthwork or foundation recommendations if this should be deemed appropriate. 4r. Cecil Smith Woward.Clyde Consultants Project No. 541673-FC01 December 13, 1984 Page 3 RECOMMENDATIONS Foundations for Structures on Nonexpansive Soil We recommend that foundations for light to medium weight commercial structures placed on nonexpansive, undisturbed soil or on nonexpansive, properly compacted fill be designed for a bearing pressure not exceeding 1500 psf for all continuous or spread footings. We recommend that footings be founded at least 12 inches and 18 inches below finished grade for one-story and two-story buildings, respectively and have a minimum width of 12 inches. In our opinion, this bearing pressure can be increased by no more than one-third for loads that include wind or seismic forces. It is also recommended that continuous footings be reinforced top and bottom with a minimum of one No. 4 steel bar. Concrete slab on grade floors should be a minimum of 4 inches in thickness and reinforced with at least welded wire fabric at the midpoint. We recommend that a 10 mil plastic membrane plus a 2 inch protective layer of wetted sand should be employed where moisture sensitive floor coverings are used. Slopes Fill slopes at the site have inclinations of approximately 2:1 (horizontal to vertical), and are approximately 8 feet high. Fill slopes were treated by overbuilding and then trimming back to grade. We recommend that structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) not be located within 8 feet of the top of a slope. We recommend that footings that are located witihn 8 feet of the top of a slope be extended in depth until the outer bottom edge of the footing is 8 feet horizontally from the outside face of the slope. Additional Fill and Utility Trenches This report discusses the fill placement observed by personnel from our firm during the period specified. We recommend that any additional fill placed, as well as backfill placed in any additional utility trenches located within 5 feet of a building and deeper than 12 inches, or backfill placed in any trench located 5 feet or more from a building and deeper than 5 feet, be compacted under our observation and tested to verify compliance with the earthwork specifications for the project. We should be contacted at least 24 hours prior to backfiLling operations. Drainage We recommend that positive measures be' taken to properly finish grade each lot after structures and other improvements are in place, so that drainage M. Cecil Smith Woward.Clyde Consultants Project No. 541673-FC01 December 13, 1984 Page 4 waters from the lot and adjacent properties are directed off the lot and away from foundations, floor slabs, and slope tops. Even when these measures are taken, a shallow ground-water or surface-water condition can and may develop in areas where no such water condition existed prior to site development; this is particularly true where a substantial increase in surface-water infiltration results from landscape irrigation. We recommend that landscape planters either not be located next to buildings and pavement areas, or be properly drained to an appropriate outlet. LIMITATIONS The elevations of compaction tests shown as finished grade (FG) tests on the attached forms corresponds to the elevations spown on the Grading Plan Carlsbad Tract No. 81-5, dated April 15,1 984, prepared by Buccola Engineering, Inc. Elevations and locations used in this report were based on field surveys done by others. The soil conditions described in this report are based on observations and periodic testing. This office should be notified of any indications that soil conditions are not as described herein. For this report, rough lot grade is defined as that grade set in the field by the grade checker from reference stakes established by the surveyor, and represents rough grade at the time we were observing the grading operation. Likewise, the indicated depths of undercutting of expansive soil and/or depths of placement of nonexpansive soil were based on the measurements made by and grades set by the contractor's grade checker. The conclusions and opinions drawn from the test results and site observations apply only to our work with respect to grading, and represent conditions at the date of our Sinai site visit. 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 damages by uncontrolled action of water. Professional judgments represented in this report are based partly on our evaluations of the technical information gathered, partly on our understanding of the proposed construction, and partly on our general experience in the geotechnical field. Our engineering work and judgments rendered meet or exceed the standard of care of our profession at this time. We do not guarantee the performance of the project in any respect. M..

It shall be the contractor's responsibility to place, spread, water , and compact the fill in strict accordance with these specifications. A soil engineer shall be the owner's representative to observe the construction of fills. Excavation and the placing of fill shall be under the direct observation of the soil engineer, and he shall give written notice of conformance with the specifications upon completion of grading. Deviations from these specifications will be permitted only upon written authorization from the soil engineer. A soil investigation has been made for this project; any recommendations made in the report of the soil investigation or subsequent reports shall become an addendum to these specifications. SCOPE The placement of controlled fill by the contractor shall include all clearing and grubbing, removal of existing unsatisfactory material, preparation of the areas to be filled, spreading and compaction of fill in the areas to be filled, and all other work necessary to complete the grading of the filled areas. MATERIALS Materials for compacted fill shall consist of any material imported or excavated from the cut areas that, in the opinion of the soil engineer, is suitable for use in constructing fills. The material shall contain no rocks or hard lumps greater than 24 inches in size and shall contain at least 40% of material smaller than I inch in size. (Materials greater than 6 inches in size shall be placed by the contractor so that they are surrounded by compacted fines; no nesting of rocks shall be permitted.) NO material of a perishable, spongy, or otherwise improper nature shall be used in fills. Material placed within 24 inches of rough grade shall be select material that contains no rocks or hard lumps greater than 6 inches in size and that swells less than 3% when compacted as hereinafter specified for compacted fill and soaked under an axial pressure of 160 psf. Representative samples of material to be used for fill shall be tested in the laboratory by the soil engineer in order to determine the maximum density, optimum moisture content, and classification of the soil. In addition, the soil engineer shall determine the approximate bearing value of a recompacted, saturated sample by direct shear tests or other tests applic- able to the particular soils. S W Woodward-Clyde Consultants 4. During grading operations, soil types other than those analyzed in the report of the soil investigation may be encountered by the contractor. The soil engineer shall be consulted to determine the suitability of these soils. IV. COMPACTED FILLS 1. General Unless otherwise specified, fill material shall be compacted by the contractor while at a moisture content near the optimum moisture content and to a density that is not less than 90% of the maximum dry density determined in accordance with ASTM Test No. D1557-78, or other density test methods that will obtain equivalent results. Potentially expansive soils may be used in fills below a depth of 24 inches and shall be compacted at a moisture content greater than the optimum moisture content for the material. 2. Clearing and Preparing Areas to be Filled All trees, brush, grass, and other objectional material shall be collected, piled, and burned or otherwise disposed of by the contractor so as to leave the areas that have been cleared with a neat and finished appearance free from unsightly debris. All vegetable matter and objectionable material shall be removed by the contractor from the surface upon which the fill is to be placed., and any loose or porous soils shall be removed or compacted to the depth shown on the plans. The surface shall then be plowed or scarified to a minimum depth of 6 inches until the surface is free from uneven features that would tend to prevent uniform compaction by the equipment to be used;. Where fills are constructed on hillsides .or slopes, the slope of the original ground on which the fill is to be placed shall be stepped or keyed by the contractor as shown on the figure included in these specifications. The steps shall extend completely through the soil mantle and into the underlying formational materials. After the foundation for the fill has been cleared, plowed or scarified, it shall be disced or bladed by the contractor until it is uniform and free from large clods, brought to the proper moisture content, and compacted as specified for fill. 3. Placing, Spreading, and Compaction of Fill Material (a) The fill material shall be placed by the contractor in layers that, when compacted, shall not exceed 6 inches. Each layer shall be spread evenly and shall be thoroughly mixed during the spreading to obtain uniformity of material in each layer. V Woodward-Clyde Consultants When the moisture content of the fill material is below that specified by the soil engineer, water shall be added by the contractor 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 the contractor by blading, mixing, or other satisfactory methods until the moisture content is as specified. After each layer has been placed, mixed, and spread evenly, it shall be thoroughly compacted by the contractor to the specified density. Compaction shall be accomplished by sheepsfoot rollers, vibratory rollers, multiple-wheel pneumatic-tired rollers, or other types of acceptable grading equipment. Equipment shall be of such a design that it will be able to compact the fill to the specified density. Compaction shall be continuous over the entire area, and the equipment shall make sufficient trips so that the desired density has been obtained throughout the entire fill. The surface of fill slopes shall be compacted and there shall be no excess loose soil on the slopes. V. INSPECTION Observation and compaction tests shall be made by the soil engineer during the filling and compacting operations so that he can state his opinion that the fill was constructed in accordance with the specifications. The soil engineer shall make field density tests in accordance with ASTM Test No. D1556-64. Density tests shall be made in the compacted materials below the surface where the surface is disturbed. When these tests indicate that the density of any layer of fill or portion thereof is below the specified density, the particular layer or portion shall be reworked until the specified density has been obtained.
