CALIF. 0202s hsCONDlD0 - 7462333 Re: Job No. 77-49 Proposed 3 Lot Site Basswood Avenue Carlsbad, California Subject: Foundation Investigation and Recommendations Dear Nr. Beck: Enclosed are the results of our foundation investigation for the above referenced site located on the north side of Basswood Avenue approximately 220 feet east of Highland Drive in Carlsbad, California. It is understood the site will be used for three lots for two story woood frame residential structures. The foundations will use concrete slabs-on-grade with concrete wall footings. Since the slope of the ground is small thare should be little if any grading or leveling. On 13 Nay 1977 six test pits were dug with a backhoe over the site as shown on the enclosed map. The test pits were logged and repre- sentative samples returned to the laboratory for further analysis. The test holes revealed the site is underlain by a uniform layer of a brown silty sand of marine sedimentary origin to the depth of interest for this project. A layer of fill material several feet thick was detected in the northeast corner of the site. The approximate limits of the fill are shown on the enclosed map. In general the fill appeared . to be a relatively clean granular soil but in'a loose condition. A field density test was taken in the native soil in Test Pit #2 at the proposed footing depth in accordance to test method ASTM D1556-64, the sand cone method. A wax density was also performed on an undisturbed sample from Test Pit 1 at 3 feet. The results are presented on the logs of the test pits found at the end of this report. A direct shear test was performed on the soil taken from the field density test. This material was remolded in the laboratory to the inplace condition of moisture and density in three 1 inch high 2.3 inch diameter brass rings. The three specimens were then sheared to failure in the undrained condition under normal loads of .5, 1.0, and 1.5 K.S.F. respectively. The values of internal friction and apparent cohesion derived from this test were used in the Terzaghi Formula in accordance with the procedure outlined in Reference 1, page 170, to compute the allowable bearing capacity. The results follow: Terzaghi Formula: Bearing Capacity = 2/3cNtc + dD N' + 4fBNj fq Assumptions: Depth of Footing, Df = 1.5' Width of Footing, B = 1.5s Nfc, N' N' = dimensionless parameters found from 9' d' Fig. 75, Ref. 1. Factor of Safety = 3. ALLOWABLE BEARING CAPACITY Soil Unit Angle of Apparent Bearing Description Density Internal Cohesion Capacity Brown Silty Sand 120 38 200 2938 (pcf) Friction (O) (psf) (psf) . SOIL AND MATERIAL TESTING LABORATORY OF NORTH COUNTY. INC. 2 Conclusions and Recommendations: 1 - It is recommended that all grading be done in accordance with the enclosed IISpecifications for the Construction of Controlled Fills" unless superseded by the following recommendations. 2 - Due to the presence of lOOS8 fill in the eastern portion of the site it is recommended that the fill be excavated to firm native soil and recompacted to at least 90% of the maximum dry density. The fill should be compacte@ for a distance of at least 10 feet outside the building perimeter., While the bulldozer is on the site it is recommended that the loose upper foot or so of native soil under the western and central lots be excavated and recompacted to form level pads. Please notify this laboratory to arrange a testing schedule prior to grading. 3 - The investigation revealed no expansive soil, groundwater or hard rock. - 4 - The tests and theqretical calculations indicate the footings may be designed to stand an allowable bearing of 2938 psf. Experience and good engineering pract;ice however, would limit this to 2500 psf. 5 - Direct all drainage'away ftorn the building so that wates is not allowed to pond around the foundation.

CALIF. 92025 ESCONDIDO - 746-2333 SPECIFICATIONS FOR CONSTRUCTION OF CONTROLLED FILLS GENERAL DESCRIPTION: The construction of controlled fills shall consist of adequate preliminary soil inv'estigations, and clearing, removal of existing structures and foundations, preparation of land to be filled, excavation of earth and rock from cut area, compaction and control of the fill, and all other work necessary to complete the grading of the filled areas to conform with the lines, grades, and slopes as shown on the accepted plans. CLEARING AND PREPARATION OF AREAS TO BE FILLED: (a) All fill control projects shall have a preliminary soil investigation or a visual examination, depending upon the nature of the job, by a qual- ified soil engineer prior to grading. (b) All timber, trees, brush, vegetation, and other rubbish shall be re- moved, piled and burned, or otherwise disposed of to leave the prepared areas with a finished appearance free from unsightly debris. (c) Any soft, swampy or otherwise unsuitable areas, shall be corrected by drainage or removal of compressible material, or both, to the depths in- dicated on the plans or as directed by the soil engineer. (d) The natural ground which is determined to be satisfactory for the support of the filled ground shall then be plowed or scarified to a depth of at least six inches (6") or deeper as specified by the soil engineer, and until the surface is free from ruts, hummocks, or other uneven fea- tures which would tend to prevent uniform compaction by the equipment to be used. (e) No fill shall be placed until the prepared native ground has been approved by the soil engineer. (f) Where fills are made on hillsides with slopes greater than 5 (hori- zontal) to 1 (vertical), horizontal benches shall be cut into firm un- disturbed natural ground to provide lateral and vertical stability. The initial bench at the toe of the fill shall be at least 10 feet in width on firm undisturbed natural ground at the elevation of the toe stake. The soil engineer shall determine the width and frequency of all suc- ceeding benches which will vary with the soil conditions and the steep- ness of slope. (9) After the natural ground has been prepared, it shall be brought to the proper moisture content and compacted to not less than 90% of max- imum density, A.S.T.M. D1557-64T. (h) Expansive soils may require special compaction specifications as directed in the preliminary soil investigation by the soil engineer. (i) The cut portions of building pads in which rock-like material exists may require excavation and recompaction for density compatibility with the fill as directed by the soil engineer. MATERIALS: The fill soils shall consist of select materials graded so that at least 40 percent of the material passes the No. 4 sieve. The material may be obtained from the excavation, a borrow pit, or by mixing soils from one or more sources. The material used shall be free from vegetable matter, and other deleterious substances, and shall not contain rocks or lumps greater than 6 inches in diameter. If excessive vegetation, rocks, or soils with unacceptable physical characteristics are encountered, these materials shall be disposed of in waste areas designated on the plans or as directed by the soil engineer. If soils are encountered during the grading operation which were not reported in the preliminary soil invest- igation, further testing will be required to ascertain their engineering properties. Any special treatment recommended in the preliminary or sub- sequent soil reports not covered herein shall become an addendum to these specifications. No material of a perishable, spongy, or otherwise unstable nature shall be used in the fills. PLACING, SPREADING AND COMPACTING FILL MATERIAL: (a) The selected fill material shall be placed in layers which shall not exceed six inches (6") when compacted.. Each layer shall be spread evenly and shall be thoroughly blade-mixed during the spreading to insure uniformity of material and moisture in each layer. (b) When the moisture content of the fill material is below that speci- fied by the soil engineer, water shall be added until the moisture con- tent is near optimum as determined by the soil engineer to assure thor- ough bonding during the compacting process. (c) When the moisture content of the fill material is above that speci- fied by the soil engineer, the fill material shall be aerated by blading and scarifying, or other satisfactory methods until the moisture content is near optimum as determined by the soils engineer. (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 accordance with A.S.T.M. 01557-64T. 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 that they will be able to compact the fill to the specified density. Rolling of each layer shall be continuous over its entire area and the roller shall make sufficient passes to obtain the desired density. The entire area to be filled shall be compacted to the specified density. SOIL AND MATERIAL TESTING LABORATORY OF NORTH COUNTY, INC. -2- * ? (e) Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compacting operations shall be continued until the slopes are stable but not too dense for planting and until there is no appreciable amount of loose soil on the slopes. Compacting of the slopes shall be accomplished by backrolling the slopes in increments of 3 to 5 feet in elevation gain or by other methods producing satisfactory results. (f) Field density tests shall be made by the soil engineer for approx- imately each foot in elevation gain after compaction, but not to exceed two feet in vertical height between tests. The location of the tests in plan shall be spaced to give the best possible coverage and shall be taken no farther than 100 feet apart. Tests shall be taken on corner and terrace lots for each two feet in elevation gain. The soil engineer may take additional tests as considered necessary to check on the uniform- ity of compaction. Where sheepsfoot rollers are used, the tests shall be taken in the compacted material below the disturbed surface. No additional layers of fill shall be spread until the field density tests indicate that the specified density has been obtained. (9) The fill operation shall be continued in six inch (6") compacted layers, as specified above, until the fill has been brought to the fin- ished slopes and grades as shown on the accepted plans. SUPERVISION: Supervision by the soil engineer shall be made during the filling and compacting operations so that he can certify that the fill was made in accordance with accepted specifications. The specifications and soil testing of subgrade, subbase, and base materials for roads, or other public property shall be done in accordance with specifications of the governing agency. SEASONAL LIMITS: No fill material shall be placed, spread, or rolled during unfavorable weather conditions. When the work is interrupted by heavy rain, grading shall not be resumed until field tests by the soil engineer indicate that the moisture content and density of the fill are as previously specified. In the event that, in the opinion of the engineer, soils unsatisfactory as foundation material are encountered, they shall not be incorporated in the grading and disposition will be made at the engineer's discretion.
