Box 71 Carlsbad, California 92008 LAGUNA RIVIERA UNIT NO. 2 CARLSBAD, CALIFORNIA In accordance with the request of Mr. Jerry L. Rombotis of your or- ganization, we have provided soil engineering services in conjunc- tion with the grading of the subject site. These services included observation of the removal of potentially expansive soil existing within two feet of rough lot grade and the testing of fill as placed and compacted. Fill was placed, compacted and tested on Lots 36 through 39, 42 through 57, 60 through 64 and 66 through 78. During the grading of Unit No. 1, excess fill was placed on two lots designated Lots A and B and adjacent streets. The fill placed was compacted and tested and the test results were presented in our reports dated flay 22 and July 7, 1958. These two lots are presentjy a part of this unit and are numbered Lots 36 and 37. 'A,copy of the reports of previous testing are attached; additional fill, which was placed on these lots during the present phase of grading has been compacted and tested and the test results are included in this report. Site preparation, compaction and testing for the subject grading were done between July 27 and September 10, 1968 in accordance with the "Specifications for Controlled Fill" in our letter dated January 10, 1967. As the site grading progressed, the compaction procedures were ,ob- served and compaction tests were made to determine the relative com- paction of the fill in place. Field observations and compaction test results indicate that the fill has been compacted to 90 percent or more of maximum laboratory density. The results of compaction tests are given on the attached forms. Laboratory tests to determine moisture-density relationships, maxilnum dry density, optimum moisture content, grain size distribution, plas- ticity characteristics and strength and swell characteristics v:ere performed on representative samples of the material used for fill. The results of laboratory tests are'given on the attached forms. - - Kamar Construction bu. Project No. 66-237-2 September 20, 1968 Page 2 Laboratory tests indicate that nonexpansive fill .was placed within 2 feet of rough grade on all fill lots noted above. - During grading of Lots 42 through 44, 46 through 51, 60 and 66 through 73, potentially expansive soil was replaced with nonexpansive fill to a depth of 2 feet where encountered within the entire level ,lot pad. - A visual inspection of the subject site at the completion of grading indicates that potentially expansive soil is.not evi,dent at finish grade on either cut or fill lots. - Footings for structures placed on nonexpansive undisturbed soil or nonexpansive properly compacted fill may be designed for a bearing pressure of 2000 pounds per square foot at a depth of 12 inches be- low rough lot grade. Footings should have a minimum width of 12 inches. - - .The elevation of compaction tests shown as finished grade (FG) tests correspond to the elevations shown on the grading plans 'for Laguna Riviera Unit.No. 2, latest revised date June 28, 1968 prepared by Raymond R. Ribal, Civil Engineer. - - - This report covers the fill placed under our observation during the dates specified above. 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 specifications of the project. 'This office shculd be contacted at least 24 hours prior to backfilling operations. Utility service trenches within 5 feet o-F a building that are 'perpend'icular to the building footings and are less than 12 inches wide and less than 3 feet deep are not subject to this recommendation. - .- - - - Structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) should not be located within 5 feet of the top of a slope. Footings located closer than 5 feet from the top of the slope should be extended in depth until the outer bottom edge of the footing is 5 feet horizon- tally from the outside face of the slope. The inspections and tests of compaction made during the period of our services on the subject site were in accordance with the local accep- table standards for this period. The conclusions or opinions drawn from the tests and site inspections apply only to our work with re- spect to grading and represent conditions at the date of our final inspection. - - WOODWRD-CLYDE 6 ASXXI~1ES Colaawn,!

Box 71 Carlsbad, California LAGUNA RIVIERA ESTATES UNIT NO. 2 LOTS A AND B CARLSBAO, CALIFORNIA In accordance with the request of Mr. Jerry L. Rombotis of your firm, we have provided soil engineering services in conjunction with the recent gradin of the subject site. These services included observation of the gradinpand compaction procedures and taking compaction tests in the fill in place. Site preparation, compaction and testing for the subject fill were done between June 22 and 29, 1967, in accordance with the Earthwork Specifications and reconmendations presented in our letter dated January 10, 1967. Fill was placed, compacted and tested on Lots A and B. Previous fill placed on these lots was done durinq the period between April 7 through 13, 1967. As the site grading proqressed, the compaction procedures were observed and compaction tests were made to determine the relative compaction of the fill in place. Field observations and compaction test results indicate that the fill has been compacted to 90 percent or more of maximum laboratory density. The approximate locations of all compaction tests to date and the limits of compacted fill are shown ion the attached Figure 1. The results 0.i compaction tests taken during previous grading on the subject lots have been reported in our letter dated May 22, 1967. Laboratory tests to determine moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plasticity characteristics and strength characteristics were performed on representative samples of the Imaterial used for fill. The results of labora.tory tests have been presented in our report dated play 12, 1967, for La9una Riviera Estates Unit No. 1. Laboratory tests indicate that nonexpansive ,fill was placed lrithin 2 feet of rough grade. - 1545 \Vii&rc Iuwl., 1683 h&s. C&f. cm017 (213) &3-5235 758 N”. Il;!avla. a?m~:e, c&f.

Footings for residential ~structures placed on nonexpansive properly compacted fill may be designed for a bearing pressure of 2,000 pounds per square foot at a depth of 12 inches below rough lot grade. The elevation of compaction tests shown as finished grade (F.G.) tests correspond to the elevations shown on the grading plans for Laguna Riviera Tract, Unit No. 1, City of Carlsbad, California, dated January 7, 1967, prepared by Raymond R. Ribal, Civil Engineer. This final report covers the fill placed under our observation during the dates specified above. Additional fill placed after these dates, as well as the backfill in utility trenches located within 5 feet of 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 of the project. Thisoffice 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. Structures that will not tolerate differential settlements (such as foundations, swimming pools, concrete decks, walls, etc.) should not be located within 5 feet of the top of a slope. Footings located closer than 5 feet from the top of the slope should be extended until the bottom edge of the footing is 5 feet horizontally from the outside face of the slope. 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 gradinq and represent conditions at the date of our final inspection. We will accept no responsibility for any subsequent changes made to the site by others or by uncontrolled action of water or by failure of others to properly repair damages caused by uncontrolled action of water.
