Geotechnical Distress Evaluation, Slope Failure Along the Fire Access Road Between Paseo Activo and Paseo Peregrino, City of San Juan Capistrano, California Introduction h accordance with your request, Lawson & Associates Geotechnical Consulting, Inc. (LGC) has performed a subsurface geotechnical investigation regarding the slope failure along a portion of the fire access road between Paseo Activo and Paseo Peregrino in the city of San Juan Capistrano, California. We have prepared this report to present our findings, conclusions, and recommendations regarding the subject slope failure. Investigation Our investigation included review of the available geotechnical data pertinent to the area of the subject slope failure, geologic mapping of the limits of the failure, and excavation and logging of one exploratory excavation within the slide mass. The exploratory trench was excavated to determine the general characteristics and vertical extent of the failed mass and the geologic characteristics of the underlying material. The location of our exploratory excavation and the limits of the slope failure are depicted on the Geologic Map (Figure 1). The trench log is attached to this report. Findings The results of our field mapping and subsurface investigation indicate the slide mass initiated approximately 4 to 5 feet north of the adjacent access road, extends approximately 40 feet horizontally down the slope and is approximately 20 feet wide. The material found to comprise the main slide mass consisted of 3 to 5 feet of moist to very moist material that had been highly deformed. This material consisted of three layers with varying proportions of silty clay, clayey silt, and clay. The uppermost material consisted of a thin 1 -foot layer of silty clay to clayey silt, which was found to be light brown, soft to slightly stiff, and dry to moist. This was underlain by approximately 2.5 feet of highly deformed material consisting of blocks of gray silty clay to clayey silt and dark brown clay. These blocks were surrounded by a matrix of light brown silty clay to clayey silt, which was moist to very moist. This was in -tum underlain by 1.5 feet of highly fractured clay to silty clay that was light gray, moist, and had yellow limonite filled fractures. Roots and rootlets were found throughout the mass and in many places these had black clayey films surrounding them. The slide materials were more saturated near the head of the slide with the greatest saturation near the southeastern side. The material appeared to become drier towards the toe of the slide. Capistrano Formation bedrock underlies the failed mass and consisted of jointed, gray and orange mottled, clayey silt to silty clay, which was moist, and medium stiff. 1020 Calle Cordillera • Suite 101 • San Clemente, CA 92673 • (949) 369-6141 • Fax (949) 369-6142 0 0 The failure appears to be a shallow surficial failure, apparently of saturated fill soils, along the base of the fill soils and above the native Capistrano Formation bedrock. Our review of the available geotechnical maps for the site indicates the location of the subject failure approximately coincides with a similar -sized failure depicted on a reviewed geologic map dated 1978, prior to site development. The as -built maps reviewed do not indicate whether or not the previously mapped failure was addressed during site grading. Minor cracking was noted within the access roadway itself, above the area of slope failure. This may be an indication of additional movement occurring in the area above the location of the current failure. It was noted that an irrigation line runs along the road just above the slide with a sprinkler head located approximately midway along the top of the slide. In addition utility mark -out revealed that a water main and sewer line run the length of the road. Conclusions The failure was found to localized and shallow, likely the result of saturated soil conditions. It does not appear to related to or an indication of a deep-seated failure, however, deeper excavation was not performed to address this possibility as part of the subject investigation. It was not determined whether the subject failure was a reactivation of the previous failure in this same location, or if the same conditions that contributed to the previous failure contributed to the subject failure. The failure was likely triggered as a result of concentrated groundwater seepage at this location. A possible contributor may be a leak in one or more of the wet utilities located above the failure, or irrigation water from the residences above. The excess moisture in the failure area and the loss of material has reduced the stability of the adjacent soils and improvements. The cracks observed in the roadway above the failure may be an indication of a forthcoming failure or at least settlement of the subgrade materials due to a loss of lateral support in the area of the failure. Recommendations Our recommendations consist of two broad areas, control of water infiltrating the soils adjacent to the roadway and reconstruction of the failed areas of the slope The source of excess water infiltration into the soils below the roadway should be found and corrected, if possible. This should include leakage tests of the utility lines underneath the road and of the irrigation lines on either side of the roadway. Additionally, irrigation water from the residences above, leaks within the pool above the subject area, or improper drainage of the pool in the direction of the failure should be investigated as possible contributors to the saturated soil conditions observed. Any leakage or other source of water should be stopped to insure that the slope does not continue to fail or fail in other areas. In addition the amount of irrigation water applied to the slopes should be checked and decreased to the least amount allowable for healthy plant growth. Our recommendation for the area of slope distress is to remove all affected material and replace with compacted engineered fill (Figure 2). All loose or otherwise deleterious soil material shall be removed until competent material is found. A key shall be excavated at the toe of the landslide with the base tilted into Project No. 031066-01 Page 2 September 10, 2003 0 0 slope at a minimum of 2 percent. The bottom and sides of the excavation shall be benched into competent material. The excavation should be filled with suitable fill material in 6- to 8 -inch lifts, moisture conditioned or dried back to approximately 2 percent above optimum moisture conditions, and compacted to a minimum of 90 percent of maximum relative compaction. Soils used for fill should be free of organics, large rocks, or other deleterious material. Once the slope is reconstructed the area should be covered in jute netting and reseeded. Based on the actual conditions encountered during grading, installation of a subdrain system may be required to divert subsurface water away the subject area to a slope face outlet. A geologist should be onsite during site regrading to determine the need for subdrainage to observe the key excavation and to provide appropriate recommendations for its construction (if deemed necessary) based on the actual conditions observed. The recommendations given above should be considered as a design that we have observed to be successful at similar sites rather than a calculated solution. Implementing the recommendations above will not eliminate all erosion or the potential for future failures, but should maintain the functionality of the improvements and reduce the potential of future slope failures. We recommend that this repair be implemented as soon as possible. Limitations Our services were performed using the degree of care and skill ordinarily exercised, under similar circumstances, by reputable engineers and geologists practicing in this or similar localities. No other warranty, expressed or implied, is made as to the conclusions and professional advice included in this report. The samples taken and submitted for laboratory testing, the observations made and the in-situ field testing performed are believed representative of the entire project; however, soil and geologic conditions revealed by excavation may be different than our preliminary findings. If this occurs, the changed conditions must be evaluated by the project soils engineer and geologist and desiga(s) adjusted as required or alternate design(s) recommended. This report is issued with the understanding that it is the responsibility of the owner, or of his/her representative, to ensure that the information and recommendations contained herein are brought to the attention of the architect and/or project engineer and incorporated into the plans, and the necessary steps are taken to see that the contractor and/or subcontractor properly implements the recommendations in the field. The contractor and/or subcontractor should notify the owner if they consider any of the recommendations presented herein to be unsafe. The findings of this report are valid as of the present date. However, changes in the conditions of a property can and do occur with the passage of time, whether they be due to natural processes or the works of man on this or adjacent properties. Therefore, the findings, conclusions, and recommendations presented in this report can be relied upon only if LGC has the opportunity to observe the subsurface conditions during grading and construction of the project, in order to confirm that our preliminary findings are representative for the site. In addition, changes in applicable or appropriate standards may occur, whether they result from legislation or the broadening of knowledge. Accordingly, the findings of this report may be invalidated wholly or partially by changes outside our control. Therefore, this report is subject to review and modification, and should not be relied upon after a period of 3 years.
