PROJECT SCOPE This limited study consisted of surface reconnaissance; subsurface explorations utilizing a track mounted excavator and rubber-tired backhoe; review of pertinent literature, analysis of the data obtained, and Preparation of this report. More specifically, the intent of this analysis was to: a) b) cl dl Explore the subsurface soil and geologic conditions in the manufactured and natural slopes on the subject lots. It should be noted that due to the heavy brush on the steep natural hillside and to the desire not to disturb the natural vegetation, our subsurface investigation was limited to the areas near the bottom of the slope. Review aerial photographs of the site taken prior to site grading in order to interpret and delineate landslide features. Describe the general geology at the site and address geologic conditions that affect the stability of the subject slopes. Provide reconsnendations to stabilize slopes determined to have factors-of-safety of less than the minimum acceptable standard of 1.5. - - .- - - - - .~~. - ..- .~ - SCSAT 8721216 March 9, 1988 FINDINGS Page 3 SITE DESCRIPTION The subject slopes are located in the southern portions of Lots 12 through 16 and the western portions of Lots 17 through 19 of Palomar Oaks Business Park, in the City of Carlsbad, California. Topography in the area of concern consists of a large natural ridge which slopes downward in a northerly direction towards Lots 12 through 16 and downward in a easterly direction towards Lots 17 through 19. Portions of the ridge near the bottom had been cut to the existing contours during the mass grading of the subject development. The flatter portions of the lots were created by cutting and filling. The topography of the ridge itself includes two larger benches one to the south of Lot 12 and one to the south of Lot 16 and a large ridge face which is incised with numerous drainage channels. Existing natural slope faces range in steepness from nearly 1:l (horizontal to vertical) to gentle in some areas. Cut slopes which were created at the lower elevations of the ridge were generally constructed at a ratio of 2:l. Elevations of the ridge range from a low of approximately 160 feet MSL to approximately 340 feet MSL near the top of the ridge. The topography of the site is shown on the topography maps contained in the pocket of this report. GENERAL GEOLDGY AND SUBSURFACE CONDITIONS GEOLOGIC SETTING AND SOIL DESCRIPTION: The project site is located in the Coastal Plains Physiographic Province of San Diego County and is underlain by Tertiary-age sedimentary deposits, Quaternary-age landslide debris, Quaternary-age alluvial deposits, and artificial fill. A brief description of the different units is presented below. SANTIAGO FORMATION (Tsl: The oldest materials encountered at the site are the buff sandstones, brown siltstones, and greenish brown mudstones of the Eocene Santiago Formation. These materials have previously been SCSAT 8721216 March 9, 1988 Page 4 - .- - ,- - - mapped as portions of the Torrey Sandstone and the Delmar Formation but are designated as the Santiago Formation for this report. The strata in the Santiago Formation are interlayered with individual beds or layers ranging from less than a centimeter to over a meter in thickness. The Santiago Formation at the project site is essentially horizontal with some local variation in dip due to such factors as original dip, initial dip, and diastrophism. Portions of the Santiago Formation have relatively high strength parameters while other portions have low strength parameters. Some remolded clay seams (also called "bedding plane faults") were encountered in the Santiago Formation at the project site. One prominent remolded clay seam appears to be related to the landslide debris at the site. The remolded seam encountered in our exploratory excavations generally consists of a single well-defined layer but is occasionally manifested as two or more separate layers within a space of only a few inches. QUATERRARY LANDSLIDE DEBRIS (Qls): Quaternary-age landslide debris, ranging in thickness from a few feet to possibly several tens of feet, is present at the site in the hillside above the level pads on Lots 12 through 16 and in a portion of the slope behind Lot 17. Most of this material occurs above an approximate elevation of 155 to 160 feet and is generally anticipated below an elevation of 280 feet. QUATERNARY ALLUVIAL DEPOSITS (Qal): The project site is located on the edge of a large natural drainage channel and contains a substantial amount of alluvial deposits. These alluvial deposits range in thickness from only a few feet to in excess of 60 feet and consist of interbedded sands, silty sands, clayey sands, and sandy clays. These deposits are located below the slope that is the concern of this report. ARTIFICIAL FILL (Qaf): The site has been graded to create several large commercial pads. The fill consists of the aforementioned native materials and ranges in thickness from a few feet to several tens of feet. This material is also located below the slope in question. - - - - - - - - .~ - .- - - SCSBT 8721216 March 9, 1988 Page 5 TECTONIC SETTING: It should be noted that much of Southern California, including the San Diego County area, is characterized by major active fault zones and associated subsidiary faults. Several small, apparently inactive faults, as well as associated joints and fractures, were observed on or near the project site. These features are usually very steep (often near-vertical) and strike in both a general northwesterly direction (subparallel to the regional structural trend) and in a general northeasterly direction (subperpendicular to the regional structural trend). One possible fault is suspected between Trench 5 and Trench 6 based on the difference in elevation of the remolded clay seam. GRDUNDWATER: Some minor seepage phenomena were encountered in random areas in the northerly trending natural drainage channels on the slope and near the toe of the slope. These phenomena are the result of recent rains saturating the topsoils and alluvial deposits which overlie less permeable bedrock deposits. SURFACE WATER: Wo surface flow was noted during the time of our field investigation. However, the majority of the site consists of a major canyon and it is anticipated that seasonal run-off may be encountered after periods of heavy rains. This potential surface flow should be taken into consideration when developing this site. BASIS OF ANALYSIS STABILITY OVERVIEW: To begin with, we believe that a brief explanation of the slope stability analysis is in order for better understanding by lay- persons. The factor-of-safety of a slope against deep-seated failure is defined as the driving forces divided by the resisting forces. If the driving forces equal the resisting forces, then the slope has a factor-of-safety of 1.0 and is close to failing. If the factor-of-safety falls below 1.0, failure occurs. The standard of practice throughout the geotechnical profession at this time is to provide a factor-of-safety of at least 1.5, or to further explain, to have the resisting forces be at least 50 percent higher than the driving forces. - - - _.~ - - - - - - - - SCS&T 8721216 March 9, 1988 Page 6 SLOPE PROFILE: In determining the stability of the slopes throughout the site, cross-sections of the existing topography were drawn at locations considered to be susceptible to landsliding or contain landslide involved soils. The location of the cross-sections which were determined to be critical are shown on the topography maps contained in the pocket of this report, while the actual profiles are presented on Plates Numbers 2 through 7. Based on the field observations by our engineering geologist, the cross-section profile, an assumed back scarp and potential failure plane were determined for the analysis of the sections. SOILS PARAMETERS: As outlined previously, a clay seam in the Santiago Formation was encountered in the exploratory trenches which appears to be the plane on which the existing slides have occurred. It was found that this seam lies essentially horizontal with some local variations in dip up to about three degrees. In the analysis of the slopes, a horizontal bedding of this seam would have generated a extremely high factor-of-safety. Therefore, an assumed inclination of three degrees out-of-slope was assumed for our analysis. Soil parameters used in our analysis were assumed for each of the four soil types anticipated. These soil types were classified as formational sandstones, slide debris, remolded clay seam or shear plane, and buttress fill. The slide debris was assumed to be disturbed sands of the Santiago Formation. The lower failure plane was assumed to be the remolded clay seam exposed at the bottom of the slide debris. The soil parameters assumed for the buttress materials were based on the assumption that the existing slide debris would be removed and replaced as uniformly compacted fill in the buttress. The following strength parameters were used in our analysis: al FORMATIONAL SANDSTONES Angle of Internal Frfction.#= 25 degrees Apparent Cohesion, c = 200 psf Weight of Soil, 8 = 125 pcf - - - - - .~ -. - .-.

The program is the PC version of a program called SLOP8R (A computer Program for Slope Stability Analysis with Non-Circular Slip Surfaces) developed at the University of California, Berkeley. The program was originally written by Stephen G. Wright in 1968 and subsequently modified for use with PC computers applying the methodology first introduced by E. Spencer. Spencer's method assumes that there is a constant relationship between the magnitude of the vertical and the horizontal interslice forces. The interslice forces are assumed to be parallel. The solution is obtained by assuming the inclination of the interslice forces, calculating the unbalanced force and moment values and comparing these with small allowable force and mcment imbalance values. If the allowable force of the moment imbalance condition is not satisfied, the assumed value of interslice force inclination is changed and the solution repeated until the computer force and moment itialance is less that the specified allowable values. Thus, the factor of safety calculated by Spencer's method satisfies both force and moment equilibrium for the overall slope. The actual computer analysis began with the determination of the failure surface on which the lowest factor-of-safety could be obtained for each of the cross-sections. This was determined by changing the angle of the back SCS&T 8721216 March 9, 1988 Page 8 -- . .- - .- slope and running the program until the minimum factor was attained. Out of the six cross-sections analyzed, only one cross-section (“1”) had a existing minimum factor-of-safety greater than 1.5. Due to the low factors of safety for the remaining cross-sections, two approaches were taken to determine corrective measures. These consisted of changing the geometry of the cross-section by cutting the existing slope down to an elevation which would attain a factor-of-safety of 1.5 or the construction of a buttress to the width necessary to attain the required factor-of-safety. The geometry of the cross-sections used in the analysis is shown on Plates Number 2 through 7. These cross-sections show the existing contours, assumed location of the slide plane, and the anticipated geometry of the cutdown sections and buttresses. The factors-of-safety obtained for the sections depicted are presented on Plates Number 21 and 22. Computer printouts of the actual program are presented on Plates Number 23 through 108. CONCLUSIONS AND RECCHENDATIONS GENERAL DISCUSSION In general, it was found that the majority of the existing slopes behind Lots 12 through 15 and portions of 16 and 17 at the subject site have an inadequate factor-of-safety in respect to transitional failure. The approximate anticipated limits of the existing landslide debris are shown on the topography map. The precise limits will need to be determined during grading operation. Based on calculations for section "I" , which cuts through a natural slope containing old landslide debris, it was determined that this slope has a factor-of-safety in excess of 1.5 in its present condition and will not require remedial grading. In addition, based on the depth of the clay seam exposed in exploratory trenches 12 through 16 and the lack of visible signs of slide debris on the slope to the rear of Lots 18 and 19, it is our opinion that this portion of the slope possesses an adequate factor-of- safety and will not require corrective grading. - - .- .- - SCSBT 8721216 March 9, I988 Page 9 .- .- ,~. Based on our past experiences with similar soils in the area, it is our opinion that the proposed 1.5:l slope will have an adequate factor-of- safety with respect to deep-seated failure. BUTTRESS In our opinion, probably the most economical means of stabilizing the slope between the two cut areas would be to construct a buttress at the toe of In the remaining portions of the slopes, the two alternatives for cutting down the slope or buttressing were analyzed. Based on the existing topography of the site, it is our opinion that the most feasible and economical solutions to obtain the necessary factor-of-safety would be to unload the head of the slide by lowering the existing benches at cross-sections J, K and L to the elevations indicated on the plot plan and cross-sections. and to buttress the area between these benches. UNLOADING OF LANDSLIDE As indicated by the results of the computer analysis of the sections 3, K and L for the unloading by cutting down the slopes to the configurations shown on the cross-sections, an adequate factor-of-safety can be obtained by this operation. The approximate limits and elevations of the cut areas are shown on the site topography map presented herewith as Plates Number 1A and 1B. It is anticipated that the back of the cut will be made into the dense, higher strength Santiago sandstones. However, due to the limited amount of field explorations, the actual contact of the landslide debris and Santiago Formation must be determined at the beginning of grading and may cause subsequent changes in the actual configuration of the cut slope. A proposed slope ratio of 1.5:1 (horizontal to vertical) is recoaanended for the cut slope. It is intended to round or curve the faces of the slopes and to transition the cut face of the slope into the proposed bench on Lot 12 to give the slopes a more natural appearance after landscaping. It is recommended that the slope be observed by a member of our engineering/geology staff during the grading operation. - - SCS&T 8721216 March 9, 1988 Page 10 the landslide. This buttress should be constructed by excavating a keyway with a minisum width of 40 feet to 60 feet, as indicated on the topography map, through the existing slide plane into the underlying formational soils and replacing the excavated soils as uniformly compacted fill. The recommended location and width of the buttress are shown on the site topography maps (Plates Number IA and lB1. For the construction of the buttress fill, a temporary 1:l back cut will be required as shown on the detail of the proposed buttress on Plate Number 8. Based on the low strength parameters of the existing side debris, there is a potential for minor failures in the temporary cut slope. If minor failures do occur, the slide material should be removed and replaced as uniformly compacted fill. The keyway should be sloped back into the existing slope at a minimum gradient of one percent. In addition, a subdrain system should be placed at the base of the base of the temporary cut back slope. This subdrain should consist of a four-inch perforated plastic pipe encased in four cubic feet per linear foot of 3/4 inch crushed rock surrounded entirely with filter fabric. In lieu of the 3/4 inch crushed rock and filter fabric, Class II permeable material may be used. The rock should extend at least twelve inches above the remolded clay seam. Further, if any wet areas are exposed by the back cut, vertical chimney drains will be required. Details of the buttress and subdrain systems are presented on Plate Number 8. - - .- .- - It is recommended that the temporary cut slope and buttress keyway be observed by a member of our engineering geology staff to verify that the slide plane has been removed and to determine if any other adverse conditions not anticipated are exposed. GRADING SITE PREPARATION: Site preparation should begin with the removal of all deleterious matter and vegetation in the area of the proposed grading. The vegetation may be stockpiled for later mulching into the proposed topsoils for landscaping purposes or exported from the site. SCSAT 8721216 March 9, 1988 Page 11 - - - If it is determined to place the soils generated by the unloading of the two benches as compacted fill on Lots 16 and 17, it is recommended that the upper twelve inches of the existing fill materials on the lots be scarified, moisture conditioned to above optimum moisture content, and be recompacted to at least 90 percent of the maximum dry densities, as determined in accordance with ASTM D1557-78, Method C. In addition, the soils exposed at the bottom of the excavation for the keyway should be prepared to receive fill as outlined above. The material removed in the keyway excavation and the fill material generated by the unloading of the landslides should be placed in uniformly compacted layers of six inches at slightly above optimum moisture contents. DRAINAGE: The site should be graded and maintained such that surface drainage is directed away from structures and the top of slopes into swales or other controlled drainage devices. EARTHWORK: All earthwork and grading contemplated should be accomplished in accordance with the attached Recommended Grading Specifications and Special Provisions. All special site preparation recommendations presented in the sections above will supersede those in the Standard Recommended Grading Specifications. All embankments, structural fill and fill should be compacted to at least 90% relative compaction at or slightly over optimum moisture content. LIMITATIONS REVIEW, OBSERVATION AND TESTING The recommendations presented in this report are contingent upon our review of final plans and specifications. The soil engineer and engineering geologist should be supplied with a copy of the final grading plans to review and verify that the plans are in compliance with this report and with Chapter 70 of the Uniform Building Code. - - - - - .- - SCS&T 8721216 March 9, 1988 Page 12 It is reconnended that Southern California Soil EL Testing, Inc. be retained to provide continuous soil engineering services during the earthwork operations. This is to observe compliance with the design concepts, specifications or recoaraendations and to allow design changes in the event that subsurface conditions differ from those anticipated prior to start of construction. UNIFORMITY OF CONDITIONS The recomaendations and opinions expressed in this report reflect our best estimate of the project requirements based on an evaluation of the subsurface soil conditions encountered at the subsurface exploration locations and the assumption that the soil conditions do not deviate appreciably from those encountered. It should be recognized that the performance of the cut and fill slopes may be influenced by undisclosed or unforeseen variations in the soil conditions that may occur in the intermediate and unexplored areas. Any unusual conditions not covered in this report that may be encountered during site development should be brought to the attention of the soils engineer so that he may make modifications if necessary.

The recoasnendations contained in the preliminary geotechnical investigation report and/or the attached Special Provisions are a part of the Recomaended Grading Specifications and shall supersede the provisions contained hereinafter in the case of conflict. These specifications shall only be used in conjunction with the geotechnical report for which they are a part. No deviation from these specifications will be allowed, except where specified in the geotechnical soil report or in other written communication signed by the Soil Engineer. OBSERVATION AND TESTING Southern California Soil and Testing, Inc., shall be retained as the Soil Engineer to observe and test the earthwork in accordance with these specifications. It will be necessary that the Soil Engineer or his representative provide adequate observation so that he may provide an opinion that the work was or was not accomplished as specified. It shall be the responsibility of the contractor to assist the soil engineer and to keep him appraised of work schedules, changes and new information and data so that he may provide these opinions. In the event that any unusual conditions not covered by the special provisions or preliminary soil report are encountered during the grading operations, the Soil Engineer shall be contacted for further recomnendations. If, in the opinion of the Soil Engineer, substandard conditions are encountered, such as; questionable or unsuitable soil, unacceptable (~-8187) .,- - _- .- ..- - -- - SCS&T 8721216 March 8, 1988 Appendix, page 2 moisture content, inadequate compaction, adverse weather, etc., construction should be stopped until the conditions are remedied or corrected or he shall recommend rejection of this work. Test methods used to determine the degree of compaction should be performed in accordance with the following American Society for Testing and Materials test methods: Maximum Density h Optimum Moisture Content - A.S.T.M. D-1557-78. Density of Soil In-Place - A.S.T.M. D-1556-64 or A.S.T.M. D-2922. All densities shall be expressed in terms of Relative Compaction as determined by the foregoing A.S.T.M. testing procedures. PREPARATIOM OF AREAS TO RECEIVE FILL All vegetation, brush and debris derived from clearing operations shall be removed, and legally disposed of. All areas disturbed by site grading should be left in a neat and finished appearance, free from unsightly debris. After clearing or benching, the natural ground in areas to be filled shall be scarified to a depth of 6 inches, brought to the proper moisture content, compacted and tested for the minimum degree of compaction in the Special Provisions or the recommendation contained in the preliminary geotechnical investigation report. All loose soils in excess of 6 inches thick should be removed to firm natural ground which is defined as natural soils which possesses an in-situ density of at least 90% of its maximum dry density. When the slope of the natural ground receiving fill exceeds 20% (5 horizontal units to 1 vertical unit), the original ground shall be stepped (~-8187) - - -- - ,- - - SCSBT 8721216 March 8, 1988 Appendix, page 3 or benched. Benches shall be cut to a firm competent soil condition. The lower bench shall be at least 10 feet wide or 1 l/2 times the the equipment width which ever is greater and shall be sloped back into the hillside at a gradient of not less than two (2) percent. All other benches should be at least 6 feet wide. The horizontal portion of each bench shall be compacted prior to receiving fill as specified herein for compacted natural ground. Ground slopes flatter than 20% shall be benched when consfdered necessary by the Soil Engineer. - - - - - Any abandoned buried structures encountered during grading operations must be totally removed. All underground utilities to be abandoned beneath any proposed structure should be removed from within 10 feet of the structure and properly capped off. The resulting depressions from the above described procedures should be backfilled with acceptable soil that is compacted to the requirements of the Soil Engineer. This includes, but is not limited to, septic tanks, fuel tanks, sewer lines or leach lines, storm drains and water lines. Any buried structures or utilities not to be abandoned should be brought to the attention of the Soil Engineer so that he may determine if any special recommendation will be necessary. All water wells which will be abandoned should be backfilled and capped in accordance to the requirements set forth by the Soil Engineer. The top of the cap should be at least 4 feet below finish grade or 3 feet below the bottom of footing whichever is greater. The type of cap will depend on the diameter of the well and should be determined by the Soil Engineer and/or a qualified Structural Engineer. FILL MATERIAL Materials to be placed in the fill shall be approved by the Soil Engineer and shall be free of vegetable matter and other deleterious substances. Granular soil shall contain sufficient fine material to fill the voids. (R-8/871 - - SCS&T 8721216 March 8, 1988 Appendix, page 4 - - - - - - The definition and disposition of oversized rocks, expansive and/or detrimental soils are covered in the geotechnical report or Special Provisions. Expansive soils, soils of poor gradation, or soils with low strength characteristics may be thoroughly mixed with other soils to provide satisfactory fill material, but only with the explicit consent of the soil engineer. Any import material shall be approved by the Soil Engineer before being brought to the site. PLACING AND COHPACTION OF FILL Approved fill material shall be placed in areas prepared to receive fill in layers not to exceed 6 inches in compacted thickness. Each layer shall have a uniform moisture content in the range that will allow the compaction effort to be efficiently applied to achieve the specified degree of compaction. Each layer shall be uniformly compacted to a minimum specified degree of compaction with equipment of adequate size to economically compact the layer. Compaction equipment should either be specifically designed for soil compaction or of proven reliability. The minimum degree of compaction to be achieved is specified in either the Special Provisions or the recommendations contained in the preliminary geotechnical investigation report. When the structural fill material includes rocks, no rocks will be allowed to nest and all voids must be carefully filled with soil such that the minimum degree of compaction recommended in the Special Provisions is achieved. The maximum size and spacing of rock permitted in structural fills and in non-structural fills is discussed in the geotechnical report, when applicable. Field observation and compaction tests to estimate the degree of compaction of the fill will be taken by the Soil Engineer or his representative. The location and frequency of the tests shall be at the Soil Engineer's (R-8/071 - - - - .- - - - - - .- - - SCShT 8721216 March 8, 1988 Appendix, page 5 discretion. When the compaction test indicates that a particular layer is less than the required degree of compaction, the layer shall be reworked to the satisfaction of the Soil Engineer and until the desired relative compaction has been obtained. Fill slopes shall be compacted by means of sheepsfoot rollers or other suitable equipment. Compaction by sheepsfoot rollers shall be at vertical intervals of not greater than four feet. In addition, fill slopes at ratios of two horizontal to one vertical or flatter, should be trackrolled. Steeper fill slopes shall be over-built and cut-back to finish contours after the slope has been constructed. Slope compaction operations shall result in all fill material six or more inches inward from the finished face of the slope having a relative compaction of at least 90% of maximum dry density or that specified in the Special Provisions section of this specification. The compaction operation on the slopes shall be continued until the Soil Engineer is of the opinion that the slopes will be stable in regards to surficial stability. Slope tests will be made by the Soils Engineer during construction of the slopes to determine if the required compaction is being achieved. Where failing tests occur or other field problems arise, the Contractor will be notified that day of such conditions by written communication from the Soil Engineer or his representative in the form of a daily field report. If the method of achieving the required slope compaction selected by the Contractor fails to produce the necessary results, the Contractor shall rework or rebuild such slopes until the required degree of compaction is obtained, at no cost to the Owner or Soils Engineer. (R-81871 - - - - - - - - - - - - - - - - SCS&T 8721216 March 8, 1988 Appendix, page 6 CUT SLOPES The Engineering Geologist shall inspect cut slopes excavated in rock or lithified formational material during the grading operations at intervals determined at his discretion. If any conditions not anticipated in the preliminary report such as perched water, seepage, lenticular or confined strata of a potentially adverse nature, unfavorably inclined bedding, joints or fault planes are encountered during grading, these conditions shall be analyzed by the Engineering Geologist and Soil Engineer to determine if mitigating measures are necessary. Unless otherwise specified in the geotechnical report, no cut slopes shall be excavated higher or steeper than that allowed by the ordinances of the controlling governmental agency. ENGINEERING OBSERVATION Field observation by the Soil Engineer or his representative shall be made during the filling and compacting operations so that he can express his opinion regarding the conformance of the grading with acceptable standards of practice. The presence of the Soil Engineer or his representative or the observation and testing shall not release the Grading Contractor from his duty to compact all fill material to the specified degree of compaction. SEASON LIMITS Fill shall not be placed during unfavorable weather conditions. When work is interrupted by heavy rain, filling operations shall not be resumed until the proper moisture content and density of the fill materials can be achieved. Damaged site conditions resulting from weather or acts of God shall be repaired before acceptance of work. (R-8187) - - - .- SCS&T 8721216 March 8, 1988 Appendix, page 7 RECOMENDED GRADING SPECIFICATIONS - SPECIAL PROVISIONS RELATIVE CDMPACTIDN: The minimum degree of compaction to be obtained in compacting natural ground, in the compacted fill, and in the compacted backfill shall be at least 90 percent. For street and parking lot subgrade, the upper six inches should be compacted to at least 95% relative compaction. EXPANSIVE SOILS: Detrimentally expansive soil is defined as clayey soil which has an expansion index of 50 or greater when tested in accordance with the Uniform Building Code Standard 29-C. - - - - - - - - - - - - - OVERSIZED MATERIAL: Oversized fill material is generally defined herein as rocks or lumps of soil over 6 inches in diameter. Oversize materials should not be placed in fill unless recommendations of placement of such material is provided by the soils engineer. At least 40 percent of the fill soils shall pass through a No. 4 U.S. Standard Sieve. TRANSITION LOTS: Where transitions between cut and fill occur within the proposed building pad, the cut portion should be undercut a minimum of one foot below the base of the proposed footings and recompacted as structural backfill. In certain cases that would be addressed in the geotechnical report, special footing reinforcement or a combination of special footing reinforcement and undercutting may be required. (R-8/871
