The scope of our services included the following: . Observing the grading operation including the installation of subdrains and the removal and/or processing of loose topsoil, existing uncontrolled fill soils and alluvial soil. . Performing in-place density tests in fill placed and compacted at the site. . Performing laboratory tests on samples of the prevailing soil conditions used for fill. . Preparing an As-Graded Geologic Map. . Preparing this final report of grading. GWLePd The grading contractor for the project was Brown, Pardee and Haney. The project plans were prepared by Rick Engineering Company and are entitled "Grading Plans for Carlsbad Tract NO. 81-29, Alicante Hills" revised dated January 17, 1985 by J. P. Engineering. The project soils report is entitled "Geotechnical Investigation for Alicante Hills, San Diego, California" prepared by Geocon, Incorporated and dated November 14, 1985. 9530 Dowdy Drive San Diego, CA 92126 619 695-2680 - - - - - - - .- - - File No. D-3573-MO2 May 12, 1986 References to elevations and locations herein were based on surveyor's or grade checker's stakes in the field and/or interpolation from the referenced Grading Plans. Grading Grading began with the removal of brush and vegetation from the area to be graded and the material was then exported from the site. Loose topsoils, existing uncontrolled fill soils and loose alluvial soils in areas to receive fill were removed to firm natural ground. Prior to placing fill, the exposed natural ground surface was scarified, moisture conditioned and compacted. Fill soils derived from on-site cutting operations and import soils were then placed and compacted in layers. During the grading operation, compaction procedures were observed and in- place density tests (ASTM D1556) were performed to evaluate the relative compaction of the placed fill. Field observations and the results of the in-place density tests indicate that the fill has generally been compacted to at least 90 percent relative compaction. The results of the in-place density tests are summarized in Table II. The tests shown as "Moisture Tests" in Table II indicate fill areas containing a sufficiently high percentage of rock as to make in-place density tests unreliable. A visual examination of these observation pits indicated that the fill material had been properly placed, that sufficient moisture was present and that the rock material was completely surrounded by soil and no "nestin?" of rocks was observed. The approximate locations of the in-place density tests are shown on the Site Plan, Figures 1, 2 and 3. Laboratory tests were performed on samples of material used for fill to evaluate moisture-density relationships, optimum moisture content and maximum dry density (ASTM D1557-70, Method C), expansion and shear strength characteristics. The results of the laboratory tests are sunnarized in Tables I and III. Slopes Both cut and fill slopes have maximum incljnations of 2.0 to 1.0 (horizontal to vertical) with maximum heights on the order of 37 feet and 25 feet, respectively. The fill slopes were periodically backrolled with a sheepsfoot compactor during construction and were track-walked with a bulldozer upon completion. Due to unfavorable geologic conditions consisting of adverse fracturini? and jointing of the formational materials in the slopes adjacent to Lots 14 and 15, they were stabilized. The stability fills included placement of backdrains and a minimum 5-foot-thick horizontal fill from face of slope to -2- _- - - - - -- - ,~~. .- .- - File No. D-3573+02 May 12, 1986 backcut. The slopes were overbuilt with select import, cut hack to finished grade and track-walked with a bulldozer. All slopes should be planted, drained and maintained to reduce erosion. Slope planting should consist of a drought-tolerant mixture of native plants and trees having a variable root depth. Finish Grade Soil Conditions During the grading operation, building pads which encountered clayey or rocky soils at grade were undercut at least 3 feet and capped with granular soils. Similarly, our observations and test results indicate that granular soils were placed within at least the upper 3 feet of finish grade on fill lots. The laboratory test results indicate that the prevailing soil conditions within 3 feet of finished grade on each building pad have an Expansion Index of 50 or less and are classified as having a "low" expansion potential as defined by UBC Standard Table 29-C. Table III presents a summary of the indicated Expansion Index of the prevailing soil condition of each lot. In addition to capping building pads as described above, the cut portion of those pads which contained a cut-fill transition within the building area or contained hardrock at subgrade was undercut at least 3 feet and replaced with compacted fill soil. Subdrains Subdrains were installed at the general locations shown on the approved Grading Plans. The subdrains were "as-built" for location and .elevation by the project Civil Engineer. Soil and Geologic Conditions The soil and geologic conditions encountered during grading were found to be similar to those described in the project geotechnical report. Formational deposits of Jurassic-aged Santiago Peak Volcanic6 and the Tertiary-aged Delmar Formation were exposed in the cut areas. The enclosed reductions of the approved Grading Plans depict the as-graded geologic conditions observed. Minor seepage was encountered in the cut slope northeast of Lots 33 through 38. The seepage appears to be the result of seasonal water daylighting through the joints and fractures of the volcanics. A series of drains were placed in the area to aid in controlling the seepage and another drain is proposed behind the retaining wall. The approximate locations of subdrains and density tests are also indicated. No soil or geologic conditions were observed during the grading which, in our opinion, would preclude the continued development of the property as planned. -3- - - - - - File No. D-3573-MO2 May 12, 1986 CONCLUSIONS AND RF/COMMENDATIONS Based upon laboratory test results and field observations, it is our opinion that the prevailing soil conditions within 3 feet of finish pad grade consist of "low" expansive soils as classified by UBC Table 29C and "low" expansive as defined by FHA/HDD criteria. We recommend the following foundation and slab design criteria for the proposed two-story residential structures. Foundations 1. It is our opinion that the proposed residential units can be supported on continuous strip footings and/or isolated spread footings providing the recommendations of this report are carefully followed. Continuous strip foundations for "very low" to "low" expansive soils should have a minimum width of 12 inches and extend at least 12 inches below the lowest adjacent pad grade. Minimum continuous footing reinforcement should consist of at least two No. 4 steel bars, one placed near the top of the footing and one placed near the bottom. 2. Isolated spread footings should be at least 1S inches square and should likewise extend at least 12 inches below the lowest adjacent pad grade. Reinforcement specifications given herein are intended for soil consider- ations only and are not to be used in lieu of structural reinforcement. 3. Footings designed as recommended above may he proportioned to impose a bearing pressure of 2,000 psf. This allowable bearing capacity is for dead plus live loads and nay be increased by one-third for transient loads. 4. It is recommended that, prior to placing steel or concrete, all founda- tion excavations be observed by a representative of Geocon, Incorporated to verify that the soil conditions do not differ significantly from those encountered during our investigation. Retaining Walls 5. All retaining wall foundations should comply with the recommendations stated in the previous section. 6. All retaining walls should be designed to resist active earth pressures equal to the force exerted by a fluid weight of 35 pcf. This assumes a level, drained and properly compacted backfill, with the hackfill extending a lateral distance of 0.5H from the heel of the retaining wall. The value is based on the supposition that no surcharge loads will be situated within a lateral distance from the top of the wall equal to the height of the wall. -A- - - - - - .- - - - ..~ - - File No. D-3573-MO2 May 12, 1986 x.1 7. Retaining walls complying with the above recommendations and supporting a slope inclined at 2:l (horizontal to vertical) should be designed to resist au active earth pressure exerted hy a fluid weight of 45 pcf. For retaining walls supporting a 1.5:1 slope, this value should be increased to 55 pcf. 8. For retaining walls that are fixed or restrained at the top (i.e. basement walls), an additional uniform pressure of 7H psf (where H equals the height of the wall in feet) should be added to the above equivalent fluid loading. 9. Passive earth pressures against properly backfilled walls and spread footings are considered to equal the forces exerted by a fluid weight of 300 pcf. These pressures can be used to resist lateral loads providing the footings or shear keys are poured neat against properly compacted fill soils or suitable formational soils and that the soil mass extends a minimum of 5 feet horizontally from the face of the footing, or three times the height of the surface generating the passive pressure, whichever is greater. However, the upper 12 inches of material not protected by floor slabs or pavement should not be included in the design for passive resistance. 10. If friction is utilised to resist lateral loads, a coefficient of friction between the soil and concrete of 0.35 may be used. 11. All retaining walls should be provided with a backfill drainage system adequate to prevent the buildup of hydrostatic forces. This is critical in the northwest portion of the site where saturation of surface and subsurface soils has been observed. A typical retaining wall drainage system is given in Figure 4. In addition, pre-manufactured drainage boards such as Miradrain may be used to facilitate drainage of the proposed retaining walls. Slabs-on-Grade 12. Concrete slabs-on-grade should possess a nominal thickness of 4 inches. Minimum slab reinforcement should consist of 6x6-lC/lP wire mesh. The bedding under slabs should consist of at least 4 inches of clean sand or crushed rock. If moisture sensitive floor coverings are planned, the use of a visqueen barrier is also recommended. At least 2 inches of the clean sand should be placed above the visqueen to allow for proper concrete curing. Care should be taken to make sure that the reinforcement is located in the middle of the slab. -5- File No. D-3573-1102 May 12, 1986 - - -~ - - - - - - _- - - Drainage and Maintenance 13. Good drainage is imperative to reduce the potential for differential soil movement, erosion and subsurface seepage. Positive measures should be taken to properly finish grade the building pads after the structure and other improvements are in place, such that drainage water from lots and other adjacent properties are directed off the lots and away from foundations and the top of slopes. Experience has shown that even with these provisions, a shallow groundwater or subsurface water condition can and may develop in areas where no such water conditions existed prior to site development; this is particularly true where a substantial increase in surface water infiltration resultsfrom increase in landscape irrigation. Pavement Sections 14. Following the placement of utilities within the street sections, rough subgrade should be prepared and R-Value tests taken. Favement recomenda- tions can be provided approximately 10 working days after R-Value sampling. LIMITATIONS The conclusions and recommendations contained herein apply on~ly to our work with respect to grading, and represent conditions at the date of our final observation, April 17, 1986. Any subseouent grading should be done under our observation and testing. As used herein, the term "observation" implies only that we observed the progress of the work with which we agreed to be involved. Our conclusions and opinions as to whether the work essentially complies with the job specifications are based on our observations, experience and testing. Subsurface conditions, and the accuracy of tests used to measure such conditions, can vary greatly at any time. We make no warranty, expressed or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. We will accept no responsibility for any subsequent changes made to the site by others, by the uncontrolled action of water, or by the failure of others to properly repair damages caused by the uncontrolled action of water. -6- File No. D-3573-MO2 May 12, 1986 - - If there are any questions regarding our recommendations or if we can be of further service, please contact the undersigned.
