RE: Job. No. 83-58 . Off Site ccess—Elm Avenue for Ca_zLsAa.d Trac 2-16 . .. V V Carlsbad, California SUBJECT: Clearance Reportof Soil Conditions V - Dear Mr.. Elliott: V. V This report is to present the results of our soil tests and observations done at your re'que'st for the grading of Elm Avenue of the above referenbed project. The recommendation for grading preparation contained in our. Preliminary Soil Investigation Report dated 23 August 1976 were followed to our satisfaction. . . . V. All ut (native ground) portions of Elm Avenue were. undercut 2 feet .and then refilled and compacted at least 90% of the maximum dry density. . V V The results of our observations, field.density and laboratory tests indicate the compacted fill and recompactedground has been placed at not less, than 90% of the maximum dry density. The approximate undercut and the fill areas tested are shown on the enclosed plot plan ; Both laboratory compaction and field density test procedures and results are presented on the following pages We understand that all grading for the referenced project has been completed. However, if additional.fill or backfill is to be placed we should be notified to insure that proper compaction is achieved Respectfully submitted, SOIL AND MATERIAL TESTING LABORATORY OF NORTH COUNTY, INC. • • • E.
