Parker 1092 Chiuquapin Avenue Carlsbad, California Ra: Job No. 2-2585 Subject: Report on Compactec * Fill on Lot No. 28, Seacrest Estates, Unit No. 1, Carlsbad, California. Dear Mr. Bancbe: In compliance with your request, an investigation was made at the subject site to determine the degree of compaction and the allowable bearing value of the foundation soils. On November 30, 1966, we inspected the site and made three <‘In-Place” field density tests of the compacted fill. The results of the field density tests are as follows: Date & Field Dry Max. Dry Test Depth Below Field Moist Density Density Compaction No. Grade, Ft. % Lbs/Cu. Ft. Lbs/ Cu. Ft. % 11-30-66 1 3. 5 8. 2 120.0 128.8 93.3 2 6. 0 1. 2 114.0 126.2 90.2 3 10.0 9. 3 119.0 130.0 91.6 FIELD INVESTIGATION A visual inspection of the site was made. No indication of settlement or slid- ing of the in-place fill was found. Loose fill material was found along the edge of the fill slope along the Northerly edge of the building pad as shown on the attached Plot Plan. It appears this loose fill has been pushed over the edge of the original building pad. A test pit, at the approximate location shown on the Plot Plan, was dug with a backhoe. Field density tests were taken at various depth in the test pit. The field density tests were taken in accordance with the A. S. T. M. D 1556- 58T Standard Test Method. Samples of the soils from each field test location were obtained for laboratory tests. DRESSELHAUS ENGINEERS I :, ; :, ,. Mr. Nicholas C. Banche Page 2 December 2, 1966 LABORATORY TESTS Moisture determinations were made from each “In-Place” field density test, maximum density determinations were performed according to A. S. T. M. D 1557-58T Standard Test Method which uses twenty-five (25) blows of a ten (10) pound hammer, falling eighteen (18) inches on each of five (5) layer8 in a four (4) inch diameter mold of l/30 cubic foot volume on soils obtained at each “in-Place” field density test location. CCNCLUSIONS The results of our inspection and investigation indicate the compacted fill soils on the lot are stable and will support the residential structure that is planned for the site. RECOMMENDATIONS The loose soils along the Northerly edge of the building pad should be removed and/or compacted to not less than ninety percent (90%) of maximum density. On the baees of our inspection and the results of the ‘In-Place” field density tests, we recommend design loads of one thousand (1003) pounds per square foot be used for square or continuous footings, placed a minimum of twelve (12) inches below grade. Vse recommend all continuous footings be reinforced with at least two (2) continuous No. 4 deformed reinforcing bars. Half of the bars should be placed within four inches (4”) of the bottom of the footing and half within four inches (4”) of the top of the footing. This recommendation is in order to minimise cracking and should not be construed as a footing design. Special consideration should be given to construction within ten (10) feet of the edge of the Northerly fill slope. To safeguard against erosion, exposed slopes should be planted.

Map No. 2 Carlsbad, California Subject: Soils Compaction Control and Inspection Gentlemen: In compliance with the request of Mr. Jerry Rombotis, ue have inspected and tested con~pacted fill soils placed on the reference site. All vegetation and debris was rerxoved from the site. The natural ground was scarified and compacted to not less than 90% of maxin um density as deternined by A. 5. T. M. E 1557-58T test method. Existing loose fill material was renioved to natural ground. Seepage along the toe of the bluff was encountered during grading. A ground drainage systen, was installed to channaliae the seepage. The fill soil was placed in horieontal layers, of not more than six (6) inches in depth, and compacted to not less than 90% of the maxmun density. Field density tests were taken in accordance with A.. S. T. M. L 1556-58T test method on each layer of fill. The results of the field density tests, as shown on the following enclosure, indicate the fill is compacted ti> n:;t less than 90% of the maximum density. The results of the field density testa and laboratory tests indicate the natural ground and compacted fill is adequate for design loads of 2500 pounds per square foot. DRESSEitlAUS ENGINEERS Page 2 3/22/66 2-2230 It is recomrxended all exposed slopes be planted to provide adequate ground cover to arrest erosion of the slope faces. Additional protective devices, such as top ber?xs and intercepting ditches, are suggested where applicable to xinin ize erosion hazards. All constructirm cn the westerly side of the property should be placed well above the high tide line. As an added precaution a rip-rap or reinf.~rced ctincrete curtain wall should be considered around the westerly end of the propose? structure as a safeguard against possible tidal action.

CLEARING, GRUBBING AND PREPARING AREAS TO BE FILLED. (a) All timber, logs, trees, brush and other rubbish shall be removed, piled and burned or otherwise disposed of so as to leave the areas that have been disturbed with a neat and finished appearance free from unsightly debris. (b) All vegetable matter shall be removed from the surface upon which the fill is to be placed, and the surface shall then be scarified to a depth of at least six inches (6”) 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. (c) Fills over three feet (3’) high shall have steps cut in the original ground at two foot vertical intervals on the slope. The steps shall be eighteen inches ( 18”) wide, more or less, and may be constructed by dozing or blading. The general direction of the bench shall run parallel with the contours and the maximum slope shall be three horizontal units to one vertical unit. (d) After the foundation for the fill has been cleared or scarified, it shall be disced or bladed until it is uniform and free from large clods brought to the proper moisture content and compacted to not less than 90% of maximum density in accordance with A.S.T.M. D1557-58T. No fill shall be placed until the soils engineer has given written clearance that the foundation is acceptable for receiving fill. MATERIALS: Material for the fill shall be free from vegetable matter and other deleterious substances, and shall not contain rocks or lumps of greater dimensions than six inches (6”). No pockets of rocks shall be allowed, PLACING, SPREADING A ND COMPACTING FILL MATERIAL. (a) The selected fill materill sh~lll be placed in layers which, when compacted, shall not exceed six inches (6”). Each layer shall be spread evenly and shall be thoroughly blade mixed during the spreading to insure uniformity of material in each layer. Form #78 -l- (b) When the moisture content of the fiil materials is low water shall be added to bring the fill within the specified density ranges (c) When the moisture content of the material is above that specified by the density range. the fill material shall be serated by blading or other satisfactory methods until the moisture con;tnt is within the density range. (d) After each layer has been placed, mixed and spread evenly, it shall be thoroughly compacted to not less than the specified maximum density in actor - dance with A, S. TV M, D1557-58T Compaction shall be by means of tamping or sheepsfoot rollers, multiple-,wheel pneumatic-tired rollers or other types of rollers. Rollers shall be of such design t~hat they will be able to compact the fill to the specified moisture content. Rolling of each layer shall be contin- uous over its entire area and the roller shall make sufficient trips to insure that the desired density has been obtained (e) Fill shall be compacted one foot beyond :he iinish grade line and cut back to grade line by removmg fluff and undercompac ted fill, (f) Field density tests shall be made by the soils engineer at intervals not exceeding two feet of fill height provided ali la.yers are tested. Where sheeps - foot rollers are used the soil may be disturbed to a. depth of several inches. Density readings shall be t&en in the compacted material below the disturbed surface. When these readings indicate that the density of any layer of fill or portion thereof is below the requiled density~ that particular iayer or portion shall be reworked until !he required densit~y ha,s been obtained, (g) The fill operation shall te continued in six imh (6”) compacted layers, as specified above, until the fiii hzs ‘been brought to the finished slopes and grades as shown on the accepted plans SUPERVISION: Supervision by the soils engineer shall be made during the fill and contracting operations so that he can ccl tify that the fill was made in accor- dance with accepted specifications SEASONAL LIMITS. No fill material shall be placed spread or rolled while it is frozen or thawing 0.1 du+mg u:,fa~\:oxable weathers conditions When the work is interrupted by heavy rain fill operations shai!. not be resumed until field tests by the soils engineer indicate t&at the nmismre conten: and density of the fill are as previously specified,, 111 t’he event :hai. in the opmicn of the engineer, the soils unsatisfactory for grading purposes are encountered. they shall not be incorporated in the grading and disposirlLn wll ‘ot made a! the engineer’s discretion, Form #78 -2 _ DRESSELHAUS ENGlNEERS CONSULTlNG CWIL ENGINEERS 528 SOUTH HlLL STREET + ocEAN81DE.

The natural ground was cleared of all vegetation and debris. The natural ground surface was scarified to a minimum depth of six (6) inches and compacted to not less than 90% of maximum density. Where trees were removed, the entire root system was excavated and the area recompacted to not less than 90% of maxi- mum density through the entire depth of the excavation. The fill soils consisting of ii dark brown silty sand and light brown clayey sand were placed in horizontal layers approximately six (6) inches in thickness and compacted to not less than 9070 of maximum density. F!eld density tests were made at interva.ls of two (2) feet of fill. The results of the field density tests are reported on the following enclosure. Basic information concerning the stability of soils is included in the attachad enclosures under Stability of Soils’ and Moisture Censity $ rvd . The approximate location and number of our soils compaction tests are shown on the attached plot plan. Marv Humphreys -2 .
