Compaction test result·s are 'presented in Table I, and the approximate locations of tests are shown on the accompanying grading plan (2 sheets), prepared by Joseph E. Bonadiman and Associates, Engineers-Planners. Fills, cuts and processing of original ground under the purview of this report has been completed under our inspection and are, to the best of our knowledge, in compliance with grading criteria for the City of Carlsbad, California. The completed work has been reviewed and is considered suitable for the intended use as a Mobil Home Park. Graded slopes are considered grossly andsurficially stable and will remain so under normal conditions. i' " f • • .. • • • • • • • • r, July 11, 1974, Work Order 100123 Page 2 LaboratolY Standard: ASTM:D 1557-70T Modified to three (3) compacted layers ' Optimum Moisture Soil Type (%) Mc.x.

Fill material consisting of the above soil types was placed in thin nfts~ watered as necessary and compacted in-place to a minimum of 90 percent of the laboratory standard. Compaction was attained by self-propelled and tractor-drawr:' sheepsfoot 'rollers. Each fill lift was treated in a like manner. The upper six (6) ~ inches of cut pads were watered as necessary, processed and compacted to a minimum of 90 percent of the laboratory standard. Street subgrade was watered, as necessary, and compacted to a minimum of 95 percent of the laboratory standard. Compaction tests, were taken in every one (1) to two (2) feet (vertically) of fill placed. The maximum vertical depth of fill placed, per this report, is on the order of seven (7) feet, on Loi" 365.

' e· INTRODUCTION This report presents the re.·sul ts o.f a t(~)l,m~ation So;ils Investigation performed on the property located at P9~nsettia Lane and the San Diego Freeway, in the City of Carlsb~d, California. The property, which covers an area of approxi- mately 55 acres will be developed into a Mobil~Hom~ Park. A two-story recreation building is expected to be Gon- s tructed on conventional contin·uous and pad footings with ~lab-on-grade concrete floor. FIELD INVESTIGATION The field investi~ation consisted oJ: excavating seven exploratory borings to depths ranging fTom ,6 feet to 16 feet. The borings were drilled using a 20 inch bucket ';'uger' drilling rig. Selected spe.cimens. of the in situ soils ware obtained by using a 2.5 inch 1.0. drive tub.e sampler equipped with brass liner rings. In addition. to the relative un-- disturbed specimens, bulk samples of the soils were obtained .' for laboratory analysis. These s'Oils obtained .in this mann,er s'erved as the basis for the laborato'ry testing ~nc1 the engineering conclusions contained in this report •. The log of the borings and a plot plan showing ,approxi- mate boring locations are includ'ed with this report. Also included are logs of Borings 1 and 15 which were drilled for the adjacent project on February 22, 1970. LABORATORY TESTING The laboratory testing consisted of performing olass.i- fication and strength tests, and debermining' in situ dry density, moisture cont~nt~ and mbisture-d~hsity relationships. Descriptions of test procedures are included in the Appendix of this report. Job No. 71-393-1 Page 1 .. ~. i I, 'I' ;-,-_:' , " '\ t ' ~I ' : ." -~"" '. I', <: , ~ . :;'" . 'I: .'

It consists of slightly rolling hills and is vacan~ with respect to·structures. ' , A row of eucalyptus trees is planted in a; nb:t:-t:.herly direction along the 70 foot elevation line near thecente.r of the property ~ The low elevation points on the property tend to be fairiy, moist. The west iow area is occupied by patches of heavy weed growth, while the east 'low area has' been' thoroughly d;i.scec1 and the topsoil is very loose. The western corner of the property has deep erosion'scars wi th a SUbstantial area of loose s.and at the bottortl o,f the fl'ow. Other than this, no abrupt topographic discontinuities we're observed. Subsurface Conditions The subsurface soils consi.st en.tirely of si,1 ty, cl'ayey and clean sands. The sands are: quite dense and generally of a very fine to roedi'um gradation. Caving occurred in three of the seven borings. The water table was encountered at depths ranging from 5 to 15 feet and perChed water was en- countered twice'. No problems other than caving were en- countered in the drilling. Soil Bearing The proposed structure may Joe supported on bot.h continuous and pad footings. Footings may be designed for an allowable bearing value of 1300 pounds per square foot for footings p1ac'ed to a minimum width and depth of·12 inches. Footings for two-story structures Job No. 71-393-1 Page 2 ; , I· :1··· . .' "">~ • I .( .. ' I '·1., , I .1 . '1· .' . . I. . . ' <I:' I' 1 1 I 'I 1- .1 .: . :'.,' ',' ".' shall be placed to a minimum depth ·of 18 inches. An ~ncrease· of 1/3 o'f the above bearing value is permissible for shor't duration loading. Settlement ... ~'. . ;~, The nature of the soils was such as to make the performing of settlement tests impractical. It is anticipated that the proposed struqture is to be a maximum of two stories in height and will possess relatively .. light footing loads. On this basis, settlement! and especially differential settlement, should be neqlig~ble,provided th? " .. surface soils are properly compacted during t'he grading •. Lateral Soil Pressure .For purposes of designing the structures for lateral forces, an allowable lateral soil pressure.value of 250 pounds per square foot per foot may 1r>~ used for tbe buildin9: ,·design. A coefficient of friction of 0.45 'm~y be used for concrete placed directly on the natural soilsi Expansive Soils ~he soils existing on the site consist of various sands. These soils are considered to be nonexpansiv~. -As a result, no special construction is required for ex- pansive soils. Concrete Slab Construction.' It is recommended that concrete floor slabs be construct·ed over a 6 mil plastic membrane. The 'pli;t$tic membrane should be properly lapped and sealed. Job No. 71-393-1' Page 3 I I I I· I. . .

I', ·1:" Shrinkage and Subsidence Based on the in situ densities of the natural soil and assuming an average fill density of, 92 percen·t relative com- paction, calculations indicate' that there will be a 3 percent d~crease in volume between the cut and fill operat~ns. In ~. addition, it is estimated that there will be a ~.2 of a fo~~' of sUbsidence due to reworking the sur:face·soils~ Grading' The grading should be done in accordance with the attached Grading Specifications: General The recommendations contained in this report are based on the results of field investigation, laboratory testing ~nd re- present our best engineering judgment. If soii conditions en- countered during the grading differ s~bstanti.al1Y from those described in this report, this office should be notified immediately, so that appropriate recommendations can be made.

ROAD ANAHEIM, CALIFORNIA 928015' 635-6220 PAVING RECOMMENDATIONS In determining the pavement design, the development was divided into two primary areas; those areas which carry , ' ,the main traffic down the center of the property and those areas carrying the feeder traffic to the individual trailei: pads. In determining the pavemeht section ,for the center 'section, a traffic index of 5.0 waS Used. In all other areas, a traffic index of 3.0 was used. The loading capacity of the surfa,ce $oils in parking areas was determined by performing Califor~ia B~aring Ratio tests. These tests were performed in accordance with the Los Angeles County Road Department Standards dated August, 1963. The primary soil, which covers. ~ost of th~ site, is slightly silty sand which was test,ed to have a CBR ,value o.f 34.

Any other material, if existing wi thin ,12 inches of finished subgrade of the street areas, should be removed and replaced with the higher strength sandy material. The subgrade material for the section containing base material may be compacted to 90 percent of maximum dens'l tY • For are'as possessing only the asphaltic concrete over com- pacted subgrade, the subgrade mate-rial shall be compacted to at least 95 percent of maximum densi ty ~ '. Likewise, any soft or unsuitable material located within street areas should either be excavated and'replaced or a new pay-ement section designed.

The direct shear tests are performed on both undistuEbed ,specimens and on samples remolded to 90 percent of A.S.T.M. Test Method D-1557-70T modified to use three layers in lieu of five. The samples are saturated to' simula,te the worst field condition and sheared at a constant rate of 0.1 inches per minute. The relationship between normal stress and shear stress is shown on the attached Direct Shear .Summa~y. The unconfined shear strength of se'lected undisturbed specimens is determined in accordance with ·A.S.T.M. Test Method D-2l66-66'1'. These tests are'performeq at the existing moisture content. The results' of' these tests .are 'shown.on· the Boring Logs. EXPANSION Tests for volume change with moisrture are performed on compac.ted soil in Ciccordahce with trSug·gested Method 6f ':£'est for Volume Change of Soil It by W.· K.

The soils encountered during the soil investigation 'consist primarily of cohesionless sand, w~ich in some areas have been cemented into a haJ;'dpan. This soil possesses a peak friction angle o'f 40°. The gross stab-ility of }-1/2 to 1 slopes in this material. is' adequat'e provid-eq. the soil is properly compacted. The surface st8:bility; which is the' "critical circle" for cohesionless ,soils, can be maintained by proper landscaping afte~ proper surface compaction.
