Box 1155 Carlsbad, California 92008 Attention: Mr. Jerry Rombotis PARTIAL REPORT OF ENGINEERING OBSERVATION AND COMPACTION TESTING (-- LAGUNA RIVIERA UNIT - LOTS 241, 242, 244 I - 249 THROUGH 251, 253, 254, 257 AND 258 CARLSBAD, CALIFORNIA - In accordance with your request, and your letter of authorization dated November 6. 1972. we have orovided soil enaineerina services in coniunction - with (1) (2) the grading-of the~subject site. The;e services included: - Engineering observation of the grading operation. Observation of the removal of highly potentially expansive soil from the top 2 feet of rough lot grade and replacing it with low to moderately expansive soil. (31 (4) Site Taking field density tests in the fill placed and compacted. Performing laboratory tests on representative samples of the material used for fill. preparation, compaction, and testing were done between November 10, .- -1 1972, and February 17, 1973, in accordance with the "Specifications for the Construction of Controlled Fill" presented in the January 6, 1966 Addendum to the "Foundation Soils Investigation for Ranch0 Aqua Hedionda Subdivision," dated July 29, 1965, prepared by Dresselhaus Engineering of Oceanside, California. Fill was placed, compacted, and tested on Lots 234 through 255 and 257 through 263. Lot256 was not graded during this phase of grading and only the following lots were completed: 241, 242, 244 through 247, 249 through 251, 253, 254, 257 and 258. It is anticipated that the remaining lots will be completed at some later date. 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 in- dicate that the fill has been compacted to 90% or more of maximum laboratory - - - - - - - - - - Kamar Construction Company Project No. 72-102-4 March 9, 1973 Page 2 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 fi,eld 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 dry density, optimum moisture content, grain size distribution, plasticity characteristics, and strengths and swell ch,aracteristics were performed on representative samples of the material used for fill. The results of lab- oratbry tests are given on the attached forms. Laboratory tests and a visual inspection indicate that nonexpansive fill was placed within 2 feet of rough grade on all finish grade fill lots noted herein, except on Lots 244, 245, 247, 249, 257 and%&; where the fill within 2 feet of rough grade has been classed as moderate in potential swell. Special foundations on the potentially expansive soils are recommended below. During grading of Lot258, potentially expansive soil was replaced with moderately expansive fill to a depth of 2 feet within the limits of the entire level lot pad. Lot 259 was undercut; however, no materials were replaced on this lot at this time. Foundations for single or two-story residential structures placed on non- expansive undisturbed soil or nonexpansive properly compacted fill may be designed for a bearing pressure of 2,000 psf at a depth of 12 inches below compacted fill or undisturbed cut lot grade. Footings should have a minimum width of 12 inches.

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. I The elevations of compaction tests, shown as finished grade (FG) tests, correspond to the elevations shown on the grading plans for "Laguna Riviera Unit No. 8," dated August, 1972, prepared by Raymond R. Ribal, Civil Engineer, Brea, California. Elevations and locations shown in this report are based on field surveys established by others. - - This report covers the fill placed under our observation during the dates specified herein. Additional fill placed after these dates, as well as the backfill in utility trenches located within 5 feet of a building and greater than 12 inches deep, or any trench 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 specifi- cations for the project. This office should be contacted at least 24 hours prior to backfilling operations.
