Carlsbad, California AUG ': iI - Attention: Mr. Jack Spoor CITY OF CARLSBAD Building Department - CARLSBAD, CALIFORNIA - - In accordance with your request, we have provided soil engineering services in conjunction with the grading of the subject site. These services included the following: (1) Engineering observation of the grading operation. - (2) Observing the removal of potentially highly expansive soil from the top 2 feet 'of lot rough grade and replacing it with non or low to medium expansive soils, - (3) Taking of field density tests in the fill placed and compacted on the subject site. - - Site preparation, compaction and testing were done between June 22 and August 15, 1970 in accordance with the "Specifications for Con- trolled Fill" in our report entitled, "Soil Investigation for the Proposed Subdivision, El Camino Mesa Unit No. 5, Carlsbad, California," dated January 17, 1967. - Fill was placed, compacted and tested on Lots 1 through 41 and 43 through 47. - As the site grading progressed, the compaction procedures were ob- served and field density tests were made to determine the relative compaction of the fill in place. Field observations and field den- sity test results indicate that the fill has been compacted to 90 percent or more of maximum laboratory density. The results of field density tests and of relative compaction, expressed as a percent of maximum laboratory density, are given on the attached forms. - - - .'< Kamar Construction Company Project No. 66-230 August 20, 1970 - Page 2 - Laboratory tests to determine moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plas- ticity 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. - - Laboratory tests indicate that nonexpansive fill was placed within 2 feet of rough grade on all fill lots noted above (except on Lots 17, 18, 19, 22, 38 and 39 where the fill within 2 feet of rough grade has been classed as low to medium in potential expansiveness). Special foundations on the potentially expansive soils are recommended below. - During grading of Lots 4 through -6, 13 through 17, 23 through 32, 41 and 43 through 47, potentially highly expansive soil was replaced with . nonexpansive or low to medium expansive fill to a depth of 2 feet - within the limits of the entire level lot pad. If structures or ap- purtenances are located beyond the limits undercut, special foundations and/or treatment of the soils should be used. - A visual inspection of cut Lot 42 at completion of grading indicates that potentially expansive soil is not evident at the rough grade sur- face. - A visual inspectionof the subject site at the completion of grading indicates that highly potentially expansive soil is not evident at - finish grade on either cut or fill lots. - - - - - - Foundations for structures placed on nonexpansive undisturbed soil or nonexpansive properly compacted fill may be d.esigned for a bearing pressure of 2,000 pounds per square foot at a depth of 12 inches below compacted fill or undisturbed cut lot grade. Footings should have a minimum width of 12 inches. Footings for single or two-story residential structures placed on low to medium expansive undisturbed soil or low to medium expansive properly compacted fill may be designed for a bearing pressure of 2,000 pounds per square foot at a depth of 12 inches below finish lot grade and in accordance with the following design requirements. 8" min.

Klema, Escondido, California. - - - 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 com- pacted under the observation of this office and tested to assure com- pliance with the earthwork specifications of 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 perpen- dicular 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 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 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 aoply only to our work with re- spect to grading 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. .
