GtEocON - - File No. D-3370-TO1 January 11, 1985 SOIL INVESTIGATION AND GEOLOGIC RECONNAISSANCE Purpose and Scope This report presents the results of our soil investigation-and geologic reconnaissance for s proposed 40-unit condominium development. The purpose of the investigation was to evaluate the surface and subsurface soil and geologic conditions encountered and to provide recommendations pertaining to the geotechnicsl aspects of the proposed site development. The scope of the investigation consisted of a site geologic reconnaissance, reviewing previous reports and serial photographs (1953) and excavating seven large-diameter borings. Samples representative of the soils encountered were obtained and returned to the laboratory for testing. A more detailed description of the procedures and findings of the field and laboratory investigation is presented in Appendices A and B, respectively. The conclusions and recommendations which follow are based on an analysis of the data obtained and our experience with similar soil and geologic conditions. As part of our study, we have xeviewed the following reports and plans: "Site Inspection and Recommendations for Construction on Expansive Soils, Lots 240 and 241 of La Costa Valley, Unit No. 5, Carlsbad, California," prepared by Benton Engineering. Incorporated and dated January 15, 1981. 0 "Land Use Study Plat" prepared by Rick Engineering Company and data November 14, 1984. ! -1- -" File No. D-3370-TO1 -, January 11, 1985 i Site and Project Description The site is irregularly-shaped, roughly resembling a triangle and is bounded by Altisma Way, Caringa Way and an existing residential development in the La Costa area of Carlsbad, California (see Site Plan, Figure 1). Elevations range from a low of approximately 100 feet MSL at the southern end of the property to a high of approximately 160 feet MSL at the northern end of the property. Existing 1.5:l cut and fill slopes up to 45 feet in height border the site which was previously graded as two relatively level pads. Sparse vegetation consisting of native grasses and chaparral cover .portions of the property. Available plans indicate that the site will be graded to form building pads for construction of 40 condominium units. We anticipate that the units will be one- or two-story wood-frame and stucco construction over one and two levels of parking. Excavations on the order of 25 feet and fills on the order of 15 feet are proposed. Soil and Geologic Conditions Three general soil types and/or geologic units were encountered during the invastigatiun. These included, in order of increasing age., fill, topsoil and formational soils of the Eocene Delmar Formation. Each of the soil types is discussed below. I - Fill. The majority of the site is covered by existing fill which was placed under the purview of Benton Engineering, Incorporated during 1970. 1 -2- -. File No. D-3370-TO1 " January 11, 1985 The fills consist predominantly of sandv clavs_anbslavov sands, which are very moist and moderately stiff to d-nsg. Varying amounts of silty material and rock and gravel fragments occur within the fill. The maximum depth of the fill encountered during the investigation was 17 feet occurring in Boring 1. Topsoil. A zone of topsoil was encountered in Borings 1, 2, 5 and 7 underlying the existing fill. The topsoil encountered was 2 to 5 feet In thickness and ranged from a & rlav to a siltv SBpd. Generally, the topsoil was dark brown, slightly mol&, moderatelv du and maloderous. The topsoil zone tends to be subject to soil creep. Underlying the topsoil was a zone of very weathered material of the Delmar Formation. Delmar Formation. On-site formational soils are of the Eocene-age Delmar Formation and consist of dB. mzL, pale Zellow-green, silty claystones and sandstoneg when into the unweathered portion. The Delmar material encountered was typically moderatelv to hmv expansive. " Groundwater No groundwater was encountered during the investigation and we do not expect groundwater to present a significant geologic hazard to the proposed development. Seepage was enconntered in Boring 5 at 8 depth of, approxi- mately 49 feet. Random seeps are common. in the Delmar Formation and cut slopes and the bottoms of overexcavations should he observed by a geologist during grading. """ -3- ” File No. D-3370-TOI .- ‘ January 11, 1985 Faulting and Seismicitv No active faults are known to exist at the site or in the immediate vicinity, and none were encountered during the course of the investigation. The nearest active faults sre the Elsinore and San Jacinto Faults, which lie approximately 25 and 49 miles, respectively, to the northeast (Map No. 1, CDMC). An offshore trace of the potentially active Rose Canyon Fault lies approximately 6 miles to the southwest. It is our opinion that the site could be subjected to moderate to severe ground shaking in the event of a major earthquake along either of the above-mentioned faults. However, seismic risk at this site is not considered to be significantly greater than that of the surrounding area in general. Landsliding No evidence of landsliQea was observed during the field investigation or noted in the review of previous reports or aerial photos. Psrtial regrading of the existing slopes is proposed and they should be observed during grading by a geologist. -4- GEOCON ,NCO”,Ol*TCD c " File No. D-3370-TOl January 11, 1985 CONCLUSIONS AND RECOMMENDATIONS General 1. No soil or geologic conditions were encountered which would preclude the development of the site as presently proposed provided the recommendations of this report are followed. by topsoil prone to soil creep will require special consideration during site development. 3. It is recommended that the existing fill and topsoils be removed and recompacted to mitigate the potential for soil creep which typically occurs within the zone of topsoil. Potential Geologic Hazards 4. No faults or indications of faults were observed on the site during the field investigation. However, the site could be subjected to moderate to severe ground shaking l.n ,the event of a major earthquake along any of the active faults in the Southern California area. It is our opinion that the seismic risk at the site is not significantly different than thht of the surrounding flreri or thr Carlsbad area in general. 5. The dense formational u, and the compacted fill soils have a verv low liquefaction uotenu. That, combined with the absence of a permanent -5- GEOCON INCORPOIAT~D .- File No. D-3370-TO1 " January 11, 1985 groundwater table within the site, renders the 0Dtenti-q r uefaction ext re- r;sanU> 6. No landslides or topographic features suggestive of ancient landslides or slope instability were noted on the site. It is our opinion that the potential for landsliding is low and should not be a constraint to site development. Grading 7. All grading should be. performed in accordance with the "Recommended Grading Specifications" presented in Appendix C. Where the recommendations of this portion of the report conflict with those of Appendix C, this section of the report takes precedence. 8. Site preparation should begin with the removal of all vegetation and other deleterious debris from areas to be graded. Such materials should be exported from the site. Material to be used in fills should be free of organic material. 9. All existing fill and topsoil should be removed and recompacted in areas which will support structures or settlement sensitive improvements. Removals should extend a Irdnirnum at 5 feet beyond the structure or a distance equal to the depth of the recompacted fill below finish grade, whichever is greater. -6- c- File No. D-3370-TO1 ” January 11, 1985 1 i 10. Structures founded partially on cut and partially on fill are not reconmended due to the increased potential for differential settlement. The Cut Portion Of cut-fill building pads should be overexcavated to a minimum depth of 3 feet below finished grade and replaced with properly compacted fill material. 11. Where removal and recompaction is not practical, s pier and grade beam foundation system should be considered. Recommendations for this type of foundation can be provided when more specific grading and floor plans are available. 12. The bottom of overexcavated areas and all other natural ground to receive fill should be scarified to a depth of approximately 12 inches, moisture conditioned to nesr optimum moisture content and recompscted. Fill should then be placed and compacted until final elevations are reached. All fill should be compacted to at least 90 percent of maximum dry density, as determined by ASRl Test Procedure D1557-70. 13. As discussed earlier, the site is overlain by moderately to highlv expansive fill and topsog. In addition, much of the formational material underlying the surficial deposits is likewise expansive. For this reason, special grading and/or foundation recommendations will he necessary. Tt is I i recommended that, where possible, and more expansive materials should be I placed in deeper fills such that the least expansive materials sre present -7- GEOCON INCOLPOLATID ~. Pile No. D-3370-TO1 January 11, 1985 within 3 feet of finish grade. In addition, cut areas where expansive soils are exposed at finish grade, should be undercut to s depth of 3 feet and replaced with material possessing low expansive potential. Rased on the results of the exploratory excavations, it is unlikely that a sufficient quantity of material possessing low expansive potential is available on- site to "cap" a significant smount of the proposed building areas. Hence, special foundation recommendations for expansive soil conditions are presented hereinafter. Groundwater .14. No groundwater table was encountered during the field investigation. Seepage was observed in Boring 1 and cut excavations should be observed by a geologist during grading to provide Fecommendations for mitigation of seepage if present at that time. Subdrains 15. No subdrains are anticipated €or the project, however, if seepage or other conditions requiring drains are encountered during grading, recommendations can then be made. Soil and Excavation Characteristics 16. The soils on the site vary from low ta high expansive. The materials I_ 1 >-. 1 required for capping of building pads to provide a very low to low I expansive condition at finished grade will have to be "mined" selected zones of the formational soils or imported. I -8- " " File No. D-3370-TO1 January 11, 1985 17. In our opinion, t :he existing fil 1 soils, topsoils and formational soils can be excavated with light to moderate effort with conventional heavy-duty grading equipment. SloDe Stability 18. The stability of the existing slopes on and adjacent to the property was analyzed utilizing the Slope Design Chart presented on Figure 2 and the findings of the field and. laboratory investigation. The results of the analysis indicate that 1.5:l cut and fill slopes will possess a factor of safety of at least 1.5 if limited to a maximum height of 90 feet and 26 feet, respectively. The maximum slope condition affecting the site occurs near the southerly property corner where B 45-foot-hi,qh, 1.5:l fill over cut slope exists. The fill portion, as disclosed by Boring 1 and field mapping of the exposed slope, is approximately 20 feet high. Proposed site grading for the parking structures will reduce portions of the fill slope height by from 6 to 22 feet. It is. therefore, our opinion that the existing slopes including the combination cut/fill slope possess a factor of safety of at least 1.5 under present, as well as future loading and geometry conditions. i Foundationo I 19. The following foundation recommendations assumeuhly expensive . -2 I actual expansion condition and corresponding foundation requirements would be presented in the final compaction report. -9- File No. D-3370-TO1 " January 11, 1985 ! ! 20. It is recommended that consideration - tensioned and foundation system in areas underlain by highly expansive soils as a means of reducing the occurrence of stress-related cracking in foundations and floor slabs. ,- 21. If it Is desired to utilize conventional continuous wa footings and concrete floor slabs, such footings should be at least 12 inches wide and should extend at least 24- adiacent pad Ue. We recommend minimum foundation reinforcement to consist of two continuous No. 5 steel reinforcing bars placed horizontally in the footings. s. and one near . the bottom. This recommendation is based on soil - - "* , characteristics only and is not intended to be in lieu of reinforcement necessary for structural considerations. 22. The allowable bearing capacity for foundations designed as recommended above is 3,000 psf for dead plus live loads. This value may be increased by one-third when considering transient loads due to wind or seismic forces. Concrete Slabs-on-Grade 23.

Slab reinforcement should consist of 6x6-6/6 welded wire mesh &laced P' within the b. It has been our experience that the mesh must be physically pulled up into the slab after the placement of concrete in order to provide proper positioning of the mesh. As an alternative to the wire mesh, Lateral Loading 25. Lateral loads may be resisted by a passive earth pressure equivalent to a fluid weight of 300 ocf for footings or shear keys poured neat against properly compacted granular soils or undisturbed formational soils. The upper 12 inches of material in areas not protected by floor slabs or pavement should not be included in design for passive resistance. 26. If friction is to be used to resist lateral loads, a coefficient of friction between soil and concrete of 0.35 is recommended. - 27.

For walls with backfill surfaces inclined at no steeper than 2.0 to 1.0, an active pressure of 42 pcf is recommended. Where walls are restra1ne;l from movement at the top, such as basement walls, a uniform horizontal pressure of 7H usf (where H is e wall in feet) should be applied .i_nn to thesm *”e. “.P.”.r”.a- ’ 29. All retaining walls should be provided with a backfill drainage system adequate to prevent the buildup of hydrostatic forces. Site Drainage 30. Adequate drainage provisions are imperative. Under no circumstances should water be allowed to pond adlacent to footings-. The lots and building pads should be properly finish graded after buildings and other improvements are in place such that surface drainage 1s directed away from foundatlons, floor slabs and the top of slopes to controlled drainage structures. 31. Present plens call for severel walls and portions of structures to be placed below grade. These areas should be carefully waterproofed and evaluated for placement of drains when detailed plans are available. 32. Our experience indicates that even with these provisions, a groundwater condition can and may develop as a result of increased irrigation, -12- GEOCON INCO~~O~ATID .* _- I i I File No. D-3370-TO1 January 11, 1985 landscaping and upslope developments.

The approximate locations of our exploratory excavations are shown on the attached Site Plan, Figure 1. The exploratory borings were drilled utilizing an ED-70 bucket auger drill rig equipped with 30-inch-diameter bucket. As drilling proceeded, relatively undisturbed samples were obtained by driving a 3-inch O.D. split-tube sampler into the undisturbed soil mass with blows from the Kelly bar falling 12 inches. Disturbed bulk samples of representative soil types were also obtained and returned to our laboratory. .- January 11, 1985 File No. D-3370-TO1 BORING 1 ELEVATIONDATE DRILLED EOUIPMENT MATERIAL DESCRIPTION Loose, very moist, tan to yellow-brown, Clayey, fine to medium SAk3 t " "- Moderately dense, very moist, tan to yellow- brown.

Such tests should be perforned to evaluate the maximum dry density and moisture content of the samples. The tests should be performed in accordance with accepted test methods of the American Society of Testing and Materials (ASTM). h .a .. 4. 4.1 i i I 4.2 I ; 4.3 4.4 4.5 4.6 4.7 I 5. 5.1 5.2 Placing, Spreading, and Compacting Fill Material Unless otherwise specified, fill material should be compacted while at a moisture content near the optimum moisture content and to a relative compaction of at least 90 percent as determined by accepted ASTM test methods. Fill materials should be placed in layers that, when compacted, have a relative compaction in conformance with the project specifications. Each layer should be spread evenly and mixed thoroughly to provide uniformity of materials in each layer. When the moisture content of the. fill material is less than that moisture content is as reconmended. When the moisture content of the recommended by the Soil Engineer, water should be added until the fill material is more than that recommended by the Soil Engineer, the fill material should be aerated by blading, mixing, or other methods until the moisture content Is as recommended. After each layer is placed, mixed, and spread evenly, it should be thoroughly compacted to the recommended minimum relative compaction. The fill should be compacted by sheepsfoot rollers, multiple-wheel pheumatic-tired rollers, or other types of compacting rollers that are capable of compacting the fill at the recommended moisture content. Each layer should be rolled continuously over its entire area until the recommended minimum relative compaction is achieved throughout the fill. The fill operation should be continued in layers, as specified above, until the fill has been brought to the finished slopes and grades shown on the approved plans. walking with a dozer, or by other suitable equipment. Compaction Fill slopes should be compacted by sheepsfoot rollers, by track- operations should continue until the slopes are properly compacted least 90 percent at a horizontal distance of 2 feet fron the slope (that is, in-place density tests indicate a relative cornpaction of at face). Observation of Grading Operations - The Soil Engineer should make field observations and perform field and laboratory tests during the filling and compaction operations, so that he can express his opinion whether or not the grading has been performed in substantial compliance with project recommendations. with accepted ASTM test methods; such density tests should be made in The Soil Engineer should perform in-place density tests in accordance the compacted materials below the disturbed surface.

Material over 4 feet in maximum dimension should not be used in fills; such material should be exported fron the site, broken into acceptably sized pieces, used Engineer and/or approved by appropriate governing agencies. for landscaping purposes, or placed in areas designated by the Soil The Soil Engineer should continuously observe the placement of over- size rock. Oversize rock should be placed in lifts not exceeding the maximum dimension of the rock, and should be placed in a manner that will not result in "nesting" of the rocks. Voids between rocks should be conpletely filled with properly compacted (minimum relative con- paction of 90 percent), fine granular material. Oversize rock should not be placed within 5 feet of finish pad grade, within 10 feet of street subgrade, or within 2 feet of the bottom of the proposed utility lines, whichever is deeper. Protection of Work During construction, the contractor should grade the site to provide positive drainage away from structures and to prevent water from age adjacent properties or finished work on the site.

In addition to the review of the above, the site was visited by a geologist from our firm on May 4, 1989 to observe the present surface site and recommendations of our original report were still applicable to the conditions. The purpose of the review was to determine if the conclusions development of the site as presently proposed. Based upon our observations of the property, the conditions at the site have not changed significantly since the date of our report. It is further our opinion that the plans have been prepared in substantial conformance with the geotechnical recommendations of our report, The maximum height and the steepness of the proposed slopes have been reduced and therefore, additional slope stability analysis is not warranted. It be changed from "one No. 5 bar top and bottom" to two No. 4 bars top and is, however, recommended that the reinforcement of the proposed footings welded wire mesh" to No. 3 bars spaced at 18 inches on center in both two No. 4 bars bottom and the slab reinforcement be changed from "6x6-6/6 directions.
