Box 71 Carlsbad, California 92008 Attention: Mr. Jerry Rombotis LAGUNA RIVIERA UNIT 5 LOTS 139 THROUGH 173 CARLSBAD, CALIFORNIA In accordance with your request and your letter of authorization dated January ,12, 1972, we have provided soil engineering services in conjunction with the gradinq of the subject site. These services included: - (1) (2) - (3) - (4) - (5) Engineering observation of the gradinq operation. Observation of the removal of loose Surface soil where encountered. Observation of the removal of highly potentially expansive soil from the top 2 feet of rough lot grade and replacing it with low to moder- ately expansive soil. Takinq field density tests in the fill as placed and compacted. Performinq laboratory tests on representative samples of the materials used as fill. - .- - - - Site preparation, compaction and testinq-for the current pradinq were done between January 6 and 26, 1972 in accordance with the "Specifications for the Construction of Controlled Fills" presented in the January 6, 1966 adz dendum to the "Foundation Soils Investiqation for Ranch0 Aqua Hedionda Subdivision" dated Jul~y 29, 1965, prepared by Dresselhaus Enpineerinq of Oceanside, California. Durinq this period of oradinq, fill was placed, compacted and tested on Lots 139 through 153 and 155 through 173. Prior grading in this area was done durinq the period of July 29, 1968 throuqh September 13, 1968 and from May 22, 1969 throuqh June 3, 1969. These period of gradinq are represented herein as tests 1 throuqh 236 taken by Woodward-Clyde & Associates. Tests 237 through 311 were taken by Woodward-Gizienski & Associates. ENGINEERING DEPT. LIBRARY City of Carlsbad 2075 Las Palmas Drive Carlsbad, CA 92009-4859 - . Kamar Construction Company Project No. 72-105-l February 14, 1972 - Page 2 - - - As the site qradinq proqressed, the compaction procedures were observed and field density testswere 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 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 qiven on the at- tached forms. Laboratory tests to determine moisture-density relationships, maximum dry density, optimum moisture content, grain size distribution, plasticity char- acteristics and strenqth and swell characteristics were performed on repre- sentative samples of the material used for fill. The results of laboratory tests are qiven on the attached forms. Laboratory tests indicate that low to moderately expansive fill was placed within 2 feet of rough qrade on fill lots 139 throuqh 152 and 156 through 173. Special foundation recommendations on the potentially expansive soils are recommended below. During qradinq of Lots 153 and 155, hiqh1.v potentially expansive soil was replaced with low to moderately expansive fill to a depth of 2 feet within the limits of the entire level lot pad. A visual inspection of cut Lot 154 at completion of grading indicates that low to moderately expansive soil is evident at the rough grade surface. A visual inspection of the subject site at the completion of gradinq indi- cates that low to moderately expansive soil is evident at finish qrade on both cut and fill lots. Foundations for structures placed on low to moderately expansive undisturbed soil or properly compacted fill may be desiqned for a bearing pressure of 2,000 pounds per square foot at a depth of 12 inches below compacted fill or undisturbed cut lot qrade. Footings should have a minimum width of 12 inches; however, since there is a considerable variation on the lots where one local area may have moderately expansive soil and a few feet away there may be low expansive soil, it is recommended that all foundations be rein- forced top and bottom with 84 reinforcinq bars. Concrete slabs should con- tain 6x6-10/10 W.W. mesh and be underlain with 4 inches of crushed gravel. - - .- Structures that will not tolerate differential settlements (such as founda- tions, swimminq pools, concrete decks, walls, etc.) should not be located within 5 feet of the top of a slope. Footinqs located closer than 5 feet from the top of a slope should be extended in deoth until the outer bottom edge of the footing is 5 feet horizontally from the outside face of the slope. The elevations of compaction tests shown as finished srade (FG) tests cor- respond to the elevations shown on the qradinq plans for "Laquna Riviera Unit No. 5", dated October 1967, prepared by Raymond R. Ribal, Civil Engineer, Brea, California. - WOODWARD -GIZIENSKI & ASSOCIATCS CO"I"LTII4T IOll A"D ,0""D1,,0II wdrl*r~ls AND cIoIocIsIo - . Kamar Construction Company Project No. 72-105-l - February 14, 1972 Page 3 - - - - This report covers the fill placed under our observation durinq 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 qreater than 12 inches deep, or any trench 5 feet or more from a buildinq 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 should be contacted at least 24 hours prior to backfillinq operations. Utility service trenches within 5 feet of a buildinq 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 durinq the period of our ser- vices on the subject site were in accordance with the local acceptable standards for this period. The conclusions or opinions drawn from the tests ahd site inspections apply only to our work with respect to qradinq and represent conditions at the date of our final inspection. We will accept no responsibility for any subsequent channes made to the site by others or by uncontrolled action of water or by failure of others to properly repair damaqes caused by uncontrolled action of water. - .- - - - EHP/JLH/LJL/jm Attachments (5) Kamar Construction Company (2) Carlsbad Buildinq Inspection Department WOODWARD.
