Supplemental Geotechnical Investigation, Carlsbad Tract No. 79-4, Carlsbad, California by Kenneth G. Osborne & Associates dated May 11, 1982. FIELD TESTING AND OBSERVATIONS As part of the clearing operation, all vegetation and debris were removed from the site. As preparation for receiving fill, the following was performed: 1. An existing desilting basin located in the northeast portion of the site in Lots 41 and 42, was removed by - - - - - - - - - - - - - - - - Job No. 3525-2 Page 2 excavating to a depth of 4.5 feet vertically below the bottom of the old basin to remove all soft unsuitable soil. The ("old" outlet) channel from the desilting basin to the offsite discharge area was excavated to a depth of 7 feet below the invert of the channel. 2. The deep, north-south trending erosional feature located in the southwestern portion of the site was excavated 2 to 4 feet below the invert of the old feature to suitable foundation soils after the vertical and near vertical side walls were sloped back. This was done to assure the temporary stability of the walls as loose fill was removed from the bottom by the scrapers. Benches were constructed into the temporary sloped walls as the fill was placed. This procedure continued until the entire erosional feature was filled to the desired finished elevations. 3. A water line located along Manzanita Street, Lots 34, 35, 36, and Arena1 Road, remains in place. A deep erosional feature located in Arena1 Road, perpendicular to El Camino Real and at the southern end of the water line was first cleared of all vegetation and other deleterious material. The existing unstable walls were sloped to competent material for temporary slope stability. The invert of the erosional feature was then undercut 1.5 feet below the previously existing bottom to firm and stable material. Benches were constructed into the sloped back xalls as the fill was placed. This procedure continued until the desired finished grade was achieved. 4. A high pressure gas line located at the top of the aforementioned erosional feature, under the existing A.C. of El Camino Real was exposed due to this erosion. The soil was recompacted under this line under the supervision of the San Diego Gas and Electric and was observed and tested by this firm. - - - - - - - - - - - - - - - - - - Job No. 3525-l Page 3 5. A storm drain located in an east-west direction through Manzanita Street and Lot 42 was removed except for a small section which was located beneath the water line left in place in this area. 6. A sewer line was left in place through Lot 8. 7. The natural ground beneath the fill lots was undercut to depths ranging up to 7 feet, depending on the depth of alluvium to be removed to obtain suitable foundation soils for the placement of compacted fill. The exposed surface was scarified and compacted to a depth varying from 6 to 12 inches. 8. The natural ground in cut lots 8, 23, 25, and 26 was undercut to a depth of 3 feet to remove expansive soils, the lots replaced with select fill and compacted. 9. The natural ground in transition lots 11, 19, 21, 38, and 39 was undercut to a depth of 3 feet to remove expansive material, then replaced with select fill and compacted. The remaining transition lots were undercut to a depth of 2 feet and then scarified an additional 12 inches, the subgrade recompacted, then filled with select material and recompacted to provide a minimum of a 36 inch blanket of compacted soil. 10. A keyway having a width varying from 15 to 20 feet and a depth varying from 4 to 5 feet was excavated at the toe of the fill slope located to the southeast of the site as shown on the attached plan. 11. A water line located along the south side of Arena1 Road, west of El Camino Real was broken during construction necessitating the repair of a portion of the fill slope located along the south side of Arena1 Road. The area repaired was approximately 50 feet in width and 12 feet in depth. Unsuitable saturated soils were removed in this area. A key was excavated to 4 feet outside of the toe of the slope to be repaired. The finished keyway had a width of 13 feet, a vertical depth of 6 feet at the deepest point, and was 110 feet long. The material excavated from this keyway was - - - - - - All fill was placed in 4 to 8 inch lifts and compacted by means of a 5'x5' sheepsfoot roller and by means of wheel- rolling with loaded scrapers and bulldozers. Fill slopes were overbuilt one to 2 feet, backrolled with a 5'x5' sheepsfoot and trackwalked with site bulldozers. The slopes were then trimmed back to planed finished grade. The required moisture was supplied by one to two 4000 gallon water trucks. The fill material consisted of both on-site and imported soils. The on-site material consisted of silty sand, sandy clay, and clayey sand, while the import consisted of silty sand. The density of the soil was determined in accordance with A.S.T.M. Test Methods D-1556 and D-2937. The test results were compared to the maximum density as determined in the laboratory in accordance with A.S.T.M. Test Method D-1557 (5 - layer). The results of the tests are presented on the attached Job NO. 3525-2 Page 4 stockpiled for drying and latter use as backfill and slope construction to be blended along with imported soil. Horizontal benches were constructed up the temporary back slope as the fill was placed. The slope was overfilled, trackr lled, 0 and then trimmed back to final grade. 12 The subgrade for Lotus Court, near Manzanita was floe ed from the water line breaks, and as a result, further inspection will be necessary at a later date to determine the suitab'lity of soils in this area. 0 13 Sprinkler lines located at the top of the slopes were jetted and probed. Density tests will be conducted at a later date to insure adequate compaction.

This slope should be landscaped with deep rooting, drought resistant and fire retardent plant cover as soon as possible to mitigate surficial weathering of the slope face. Faulting or fault traces were not observed during the site grading. LABORATORY TESTING Tests for volume change with moisture were performed on compacted soil in accordancw with the UBC Test Standard 29-2. The maximum density of the soil was determined in ac- cordance with A.S.T.M. Test Method D-1557 (5 layer). - sandstone matrix. Tn general, the De1 Mar formation is undeformed with localized beds indicating southwesterly dips to 16 degrees. Bedrock exposures were encountered along El Camino Real and in the cut portions of the hills, while lower relatively flat lying portions of the site were comprised of alluvium colluvium and previously placed artificial fill. Adverse geologic conditions such as continuous planes of geologic weakness resulting from out-of-slope dips, fractures, shears or faulting were not observed during the grading operations. REMARKS AND RECOMMENDATIONS - Footings and Bearing Footings may be designed for an allowable bearing value of 1500 - pounds per square foot provided they are placed to a minimum width of 12 inches and a minimum depth of 12 inches below the lowest adjacent final grade. An increase of l/3 of - the above bearing value is permissible for short duration loading. - - - - - - - - - - - - - - - - - Job No. 3525-l Concrete Slab Construction Page 6 Tt is recommended that concrete floor slabs in areas to be covered with moisture sensitive coverings be constructed over a 6 mil plastic membrane. The plastic membrane should be properly lapped, sealed, and protected with sand. It is cautioned that concrete slabs in areas to receive ceramic tile or other crack sensitive floor coverings must be designed and constructed to minimize hairline cracking. Expansion The results of tests indicate that the soils existing on the site are nonexpansive to highly expansive.

As a result, no special type concrete or construction is considered necessary for soluble sulfates for this project. Lots 1, 3, 8, 12, 19-20, 25, 28, and 34-42: A soluble sulfate content in excess of 0.20 percent is considered to be potentially detrimental to most standard concrete mixes. As a result, the soluble sulfate content of these soils should be a determining factor in the selection of the type of concrete to be used on this site. J" andscaping All cut and fill slopes should be planted with deep rooting, fire and drought resistant plant material recommended by your landscape architect, as soon as possible to minimize surficial weathering of the slope faces. - - 7- - - - - - - - - - - - - Job No. 3525-l Page 11 Limits of Reporting This report covers the grading performed between the dates of August 8, 1984 and October 8, 1984 and for the portions of the project as described herein which includes Lots l-43 of Tract 79-4 and a portion of Lots 44 and 45.
