This addendum records our observations and the results of tests performed in connection with our inspection of the compaction of filled ground placed on certain areas of the above subject property. This property is more particularly referred to as Assessors Parcel Nos. 223-190-05, -06, -07, and -08 in the City of Carlsbad, County of San Diego, State of California. The grading reported herein was accomplished on November 3, 1986. The elevations of fill at which the tests were taken and the final test results are presented on page T-15 under "Table of Test Results". The laboratory determinations of the maximum dry density and-the optimum moisture content of the fill soils are set forth on page L-l under "Laboratory Test Results". The approximate location of the filled ground and the field density tests are presented on Drawing No 6 revised November 4, 1986, entitled "Approximate Location of Compacted Filled Ground". The results of the tests and observations indicate that the soils placed on subject site under our inspection have been compacted to at least 90 percent of maximum dry density. We note for clarity that the building pad for lot 278 is complete. The remainder of our third interim report of compacted filled ground remains in force. Pages T-15, L-l, and Drawing No. 6 are parts of this report.
