All areas to receive fill were then scarified to a depth of at least 8 inches, watered to optimum moisture and com- pacted to a minimum of 90% relative compaction. The soils used in the fill were obtained on the site. The fills were re spread in thin lifts not exceeding 6 inches, watered approximately optimum moisture content and compacted by a sheepsfoot . Inspection was continuous during major phases of the fill operation and placement. In-Place Density Tests, in accordance with the Sand Cone Method, ASTM Des: D-1556-65 (68}, were taken at a frequency sufficient to insure adequate control of the fill operations and to provide a cross-section of the compaction obtained . Materials used for fill were non-expansive (less than 3%). Areas failing to meet the 90% minimum were brought to the contractor's atten- tion and we re reworked to passing specifications. A minimum relative c ompaction of 90% or better was obtained. The test results and their locations are enclosed. The allowable bearing capacities recommended in our Foundation Investigation Report of June 18, 1973 (.fl,P-886-73) are still considered valid (i.e. , 17 SO psf for continuous footings placed in compacted fill or undisturbed natural ground at depths of 12 inches). -2- 1824 E.

This report represents the results of our PreliminaIY Soils Analysis of the subject property located in Carlsbad, California. The purpose of the investigation was to determine and evaluate the characteristics of the soils affecting the gross stability of the pro- perty, and to present our opinion on the suitability of the property for the construction of the proposed residences. The accumulated data was obtained through field explorations, engineering consultations and numerous laboratory analyses and testings. Drilling was done on June 15, 1973, and our investigation was completed on June 20, 1973. 11124 E.

The load on the footings is not available at the present time. PHYSIOGRAPHY: The location of the subject site is illustrated on the attached Plot Plan. The subject property , which is rectangular in shape, is located between Stratford Lane and Knowles Street, east of the San Diego Free- way in the City of Carlsbad. The property is relatively level, generally slopes to the east at a rate of 5 to 10 percent. The property is currently being utilized as a avocado orchard. There is a single wood frame structure on the eastern portion ot the site with a avocado orchard south of the structure. Four pads have been graded on the western portion of the site which are basically all cut pads. The site is bordered on the east and on the west by residential structures, and by Knowles Street on the south and Stratford Lane on the north. Drainage runs toward Knowles Street and Stratford Lane. Present planning indicates that the property is to be sub-divided into seven residential lots. three have yet to be cut. It ls understood that the three building pads left to be g raded will be only shallow cuts and fills • 1824 E.

Slight shrinkage cracks in the earth mater- ials were observed indicating the nature of the soils are not highly expan- sive. The results of the swell tests performed on undisturbed samples of typical on-site materials indicate the soils as slightly expansive. Please refer to page 20 for Expansion Test Data. EARTH MATERIALS: Subsurface Strata The soils on the site consist of a mantle of silty sand with slight traces of clay, moderately dense, dry, reddish brown to a depth of 2 feet with underlying sands, fine to medium, with a clay binder, very dense, reddish brown to a depth of 12 to 16 feet. Some of the underlying strata down to a depth of 10 to 15 feet indicate~ that there is less of a clay binder than there is in some of the other areas. The soils are con- sistent throughout the whole site. No groundwater was encountered. SUMMARY AND RECOMMENDATIONS: Site Preparations The most significant problem to be dealt with on the four pads which have already been graded, is the roots and tree branches a·nd other matter missed during clearing. These roots fo the building and the pavement areas 1824 E.

Upon excavation of roots from Lot A and Lot B, the westerly 1 S feet :t,:~ of the building pad area should be elllCavated to a depth of 2 feet a~ re-compacted to 90% of maximum dry density obtained by test method f'-""' ASTM Des: D-1557-70, Method A (see Maximum Density/Optimum Moisture Determination sheet). The remainder of the site which has not yet been graded should follow the below recommendations. A. All heavy vegetation and debris in the building, pavement or fill areas should be removed to avoid organic decay, and the cavities created brought to grade with properly compacted material. Any obstruction that are re- vealed during grading operations, along with the above mentioned ob- struction, should be removed and the cavity created brought to grade with compacte d mate rial. These materials should be legally disposed of off the site be fore new construction is initiated. B. Soil, alluvium, or rock materials determined by the Soils Engineer as being unsuitable for placement in compacted fills shall be removed and wasted from the site. Any material incorporated as a part of a com- pacted fill must be approved by the Soils Engineer. 1824 E.

After the ground surface to receive fill has been cleared, it shall be scarified, disced or bladed by the Contractor until it is unifonn and free from ruts , hollows , hummocks, or other uneven features which may pre- vent uniform compaction. The scarified ground surface shall then be grought to optimum moist- ure, mixed as required, and compacted as specified. If the scarified zone is greater than 12 inches in depth, the excess shall be removed and placed in lifts restricted to six inches. Prior to placing fill, the ground surface to receive fill shall be scari- fied to a depth of 8 inches, watered or aerated to near optimum moisture content and re-compacted to 90% of the maximum dry density obtained by test method ASTM Des: D-1557-70, Method~ (see Maximum Density/ Optimum Moisture Detennination sheet).

Material used in the compacting process shall be evenly spread, watered, processed, and compacted in thin lifts not to exceed 6 inches in thickness to obtain a uniformly dense layer. The fill shall be placed and compacted on a horizontal plane unless otherwise approved by the Soils Engineer. E. Each layer shall be compacted to 90% of the maximum density ob- tained by ASTM De s: D-1557-70, Method A (5 layer). It the moisture content or relative density varies from that required by the soils engineer, the contractor will rework the fill until it is approved by the Soils Engineer. F. All fills s hall be keyed and benched through all topsoil, alluvium, colluvium, or c re ep material, into sound bedrock or firm formation mat- e rial where the slope receiving fill exceeds a ratio of five horizontal t o one vertical in accordance with the recommendations of the Soils Engineer. 1824 E.

The bearing cap- acity may be increased by thirty-three percent for the total of all loads, dead and live, including seismic and wind. Lateral Pressures The recomme nde d active pressure to be considered considered in the design is 40 pounds per square foot. A passive lateral pressure of 220 pounds per square foot and a coefficient of friction of O. 40 between the soils a nd the concre t e foundation may be assumed. Settle me nt and Volume Reduction The maximum s e ttlement of underlying strata as a result of fill place- me nt is expected to be on the order of 1. 0 inches.

Visual classification wes performed according to the Unified Soil Classification System. Moisture determinations were performed on every sample lot, and unit weight determinations were performed on every undisturbed sample lot. Results of density and moisture contents, along with soil classifications, are shown on the Logs of Borings attached. The laboratory test results, which have been performed on all the samples of the borings, are considered to be representative of the soils under- lying the site. Direct shear tests were performed on selected undisturbed sam- ples in order to determine the shear strength of the soils. These tests were performed at increased moisture contents and at various surcharge pressures in order to simulate adverse field conditions. The yield point values determined from the shear tests are presented on the attached Direct Shear Test Data. Confined Consolidation Tests were performed on undisturbed samples in order to establish the compressibility of the soil. Water was added at an axial load of 1300 pounds per square foot in order to simulate the effect of moisture on the compressibility. The maximum load applied was 52 00 pounds per square foot.

Grephic plots of the Load Consol- idation Tests are included in this report. Expansion tests were performed on the undisturbed samples at varying depths in order to determine the volume change of the soil due to changes in the moisture content. The samples were confined under a normal surcharge pressure of 60 pounds, saturated, and the resulting expansion measured. Afterwards, the samples were allowed to dry and the resulting moisture loss was calculated. In order to determine the maximum density of the soil, which establishes the compaction required during grading and backfilling, max- imum density tests were performed on representative samples of the upper soils. The compaction method used was ASTM Des: 1557-70 , Method A (five layers, 25 blows per layer, ten pound hammer, 18 inch drop, 4 inch diameter, 1/30 cubic foot mold. 1824 E.

Sampling Soils encountered were continuously logged by our Geologist. Undis- turbed ring samples and disturbed bulk samples were obtained and trans- ported to our laboratory in moisture sealed containers to ensure environ- mental conditions for controlled laboratory analyses. Undisturbed ring samples were acquired for shear, consolidation, ex- pansion, and density testing. Disturbed bulk samples, which are beneficial in establishing characteristics of typical material when used as compacted fill, were also obtained. Standard Penetration Test A bulk sample was also acquired through the Standard Penetration Test which is made by dropping a hammer weighing 140 pounds onto the standard drill rod from a height of 30 inches in free fall. The N (number of blows) necessary to produce a penetration of one foot is regarded as the penetration resistance which assists in computing the bearing value. 1824 E.

Our laboratory test on the samples of the materials encountered confirm the adequacy of the soils to support construction of the residences on this site. Areas not explored by our borings are assumed to be consistent wtth those tested. If conditions other than those noted in this report are discovered during construction, this office should be notified so that proper adjustments can be made. This opportunity to be of service is sincerely appreciated. If you have questions, please feel free to call us. We will be happy to extend our ser- vices to solve any soils or foundation problems that may develop during design or construction of your project.
