Clyde Cm.9ultonts May 24, 1974 Project No. 72-102-4 - Kamar Construction Company P.O. Box 71 Carlsbad, California 92008 Attention: Mr. Jerry Rombotis - -. - - - FINAL REPORT OF ENGINEERING OBSERVATION AND COMPACTION TESTING LAGUNA RIVIERA UNIT NO. 8 LOTS 225 THROUGH 263 CARLSBAD, CALIFORNIA In accordance with your request, and your letter of authorization dated November 6, 1972, we have provided soil engineering serivces in conjunction with the grading of the subject site. These services included: (1) Engineering observation of the grading operation. (2) Observation of the removal of loose surface soils where encountered prior to placing fill. (3) Observation of ~the removal of highly potentially expansive soil from the top 2 feet of rough lot grade and replacing it with nonexpansive soil, low to moderatelv exoansive soils or. in the case of Lot 226, with moderately expansjve soil. . (4) Taking field density tests in the fill placed (5) Performing laboratory tests on representative used for fill. and compacted. samples of the material Current site preparation, compaction and testing were done between April 1 and May 3, 1974 in accordance with the "Specifications for Controlled Fill" in our updated soil investigation report entitled "Laguna Riviera Unit No. 8, Carlsoad, California", dated April 30, 1973. , - - - - - - - Kamar Construction Company Project No. 72-102-4 May 24, 1974 Page 2 Fill placed during the current phase of grading was compacted and tested onLots 225 through 263. Prior fill was placed, compacted and tested on Lots 237, 238, 240 through 244, 248, 250, 252, 253, 256 and 257 during a previous grading period. In addition, Lots 225 through 229, 245 through 247, and Lot 263 were partially graded during the grading of Unit 7, but were regraded during the current period. All the lots in the subject subdivision are fill lots. As the site grading progressed, the compaction procedures were observed, and field density tests were made to determine the relative compaction of the fill in place. Field observations and field density test results indicate that the fill has been compacted to 90% or more of maximum laboratory density. The approximate locations of field density tests and the limits of compacted fill have been recorded on a copy of the grading plan for reference. The results of field density tests and of relative compaction, expressed as a percent of maximum laboratory density, are given on the attached forms. Laboratory tests to determine moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plasticity characteristics, and strength and swell characteristics were performed on representative samples of the material used for fill. The results of laboratory tests are given on the attached forms. During the grading operation certain lots were specially treated to provide a specified depth of selected soil at rough grade. Laboratory tests and visual inspection indicate that nonexpansive fill was placed within 2 feet of rough grade on all fill lots noted herein, with the exception of the following: Lot 226 where the fill within 2 feet of rough. grade has been classed as moderate in potential swell with a swell of approximately 8%; and on Lots 230, 233, 240 and 247 where the fill within 2 feet of rough grade has been classed as low to moderate in potential swell with swell of 3 to 6%. The percent swell is measured on samples recompacted at optimum moisture content, placed under an axial load of 160 psf and soaked in water. Special foundations on the potentially expansive soils are recommended below. On Lots 225, 229, 231, 234, 235, 238, 248, 249, 250, 254 and 257 through 262 potentially expansive soil was excavated and replaced with nonexpansive fill to a depth of 2 feet below rough lot grade and within the limits of the entire level lot. On Lots 226, 230 and 233 highly potentially expansive clay was excavated and replaced with moderately expansive or low expansive fill to a depth of 2 feet below rough lot grade and within the limits of the level lot. , WOODWARD.GlZlENSKl A ASSOCIATES co*~"LllNP IO!, AllO ~0"1(01,10* ~*w4~I"* lP.0 cIc.LocIsI~ - - - - - .- - Kamar Construction Company Project No. 72-102-4 May 24, 1974 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 inspecting the removal and replacement of expansive soils. Likewise the depths of undercutting of'expansive soil and/or depths of placement of nonexpansive soil were in accordance with measurements made by and grades set by the contractor's grade checker. On those lots where potentially expansive soil is evident or where it is encountered in footing excavations, special foundation design should be observed. Special foundations for single or two-story residential structures on lots that contain such potentially expansive soil,, should be designed in accordance with the following recommendations: (1) Foundations for single or two-story residential structures placed on nonexpansive properly compacted fill may be designed for a bearing pressure of 2,000 psf (dead plus live loads) at a depth of 12 inches below compacted fill or undisturbed cut lot grade. All footings should have a minimum width of 12 inches. This pressure may be increased by one-third for loads that include wind or seismic forces. (2) Foundations for single or two-story residential structures on Lots 230, 233, 240 and 247 that contain potentially low to moderately expansive soil may be designed for an allowable soil bearing pressure of 2,000 psf and should include the following reinforcing.

Footings located closer than 5 feet from the top of a slope should be extended in depth until the outer bottom edge of the footing is 5 feet horizontally from the outside face of the slope. - - - The exposed soils within footing excavations and under slabs should be allowed to dry out before construction, and should be thoroughly prior to placement of concrete. The above design recommendations are not intended to eliminate heave, are,intended to minimize its effects. - - - The elevations of compaction tests, shown as finished grade (FG) tests, correspond to the elevations shown on the grading plans for "Tract 73- 5" with the latest revision dated December 31, 1973, prepared by Raymond R. Ribal, Brea, California. Elevations and locations shown in this report are based on field surveys established by others. - - - This report covers the fill placed un~der our observation during the dates specified herein. Additional fill placed after these dates, as well as the bac~kfill in utility trenches located within 5 feet or more from a building and in excess of 5 feet in depth, should be compacted under the observation of this office and tested to assure compliance with the earthwork specifications for the project. This office should be contacted at least 24 hours prior to backfilling operations. Utility service trenches within 5 feet of a building that are perpendicular to the building footings and are less than 12 inches wide and less than 3 feet deep are not subject to this recommendation. The inspections and tests of compaction made during the period of our services on the subject site were in accordance with the local acceptable standards for this period. The conclusions or opinions drawn from the tests and site inspections apply only to our work with respect to grading and represent conditions at the date of our final inspection. I WOODWARD.
