This as- graded report of mass grading summarizes our geotechnical observations, geologic mapping, field and laboratory test results, and the geotechnical conditions encountered during the mass grading operations for the project. In addition, this report provides conclusions and preliminary recommendations for the proposed development of the site. As of this date, the mass grading operations for Planning Areas PA-13, PA-14, and PA-15 are essentially complete. However, the each Planning Area is currently sheet-graded and will still need to be fine graded in order to construct the planned building pads, driveways/parking areas and other anticipated site improvements. A• final as-graded report documenting the additional grading operations and providing (if necessary) addendum and/or additional geotechnical recommendations relative to the proposed development should be prepared upon completion of the future grading operations. The Mass Grading Plans for Bressi Ranch project, prepared by Project Design. Consultants (PDC, 2003a), were utilized as a base map to present the as-graded geotechnical conditions and approximate locations of the field density tests. The As-graded Geotechnical Map (Plates I and 2) is presented in the pocket at the rear of the text. L.• 4 I -1- Leighton 971009-014 1.1 Project Descriøtion The Bressi Ranch development is located southeast of the intersection of El Camino Real and Palomar Airport Road in the central portion of the City of Carlsbad, California (Figure 1). The. site consists of an irregular-shaped piece of property bordered on the north by Palomar Airport Road, on the west by El Camino Real, on the southwest and south* by the La Costa - The Greens property, and by the Rancho Carrillo development and Melrose Drive to the east. Planning Areas PA-13, PA-14, and PA-15 are located in the north-central and eastern portion of the Bressi Ranch project. The proposed development of Planning Areas PA-13, PA-14, and PA-15 is anticipated to consist of retail, commercial, and/or community developments, all of which will have associated driveways, parking areas, underground utilities, manufactured slopes, and associated open areas or landscaped areas. -3- Leighton 971009-014 2.0 SUMMARY OF MASS GRADING OPERATIONS The mass grading operations for Planning Areas PA-13, PA-14, and PA-15 were performed between July 2003 and July 2004. The grading operations were performed by Nelson and .Belding while Leighton and Associates performed the geotechnical observation and testing services. Our field technicians were on site full-time during the grading operations while'our field and project geologists were on site on a periodic basis. Grading of the site included: 1) the removal of potentially compressible fill soils, topsoil, colluvium, alluvium, landslide deposits, and weathered formational material; 2) the excavation of stability fill keys; 3) the excavation of fill slope keys; 4) preparation of areas to receive fill; 5) the placement of subdrains in the canyon bottoms and stability fill keys; 6) excavation of formational material; and 7) the placement of compacted fill soils. Up to approximately 45 feet of cut was excavated and a maximum of approximately 95 feet of fill was placed within the limits of Planning Areas PA-13, PA-14, and PA-15. The as-graded geotechnical conditions are presented on the As-Graded Geotechnical Map (Plates 1 and 2). 2.1 Site PreDaration and Removals Prior to grading, the areas of the proposed development were stripped of surface vegetation and debris and these materials were disposed of away from the site. Removals of unsuitable and potentially compressible soils (including undocumented fills, topsoil, colluvium, alluvium, landslide deposits, and weathered formational material) were made to competent material. The removals of potentially compressible material were performed in accordance with the recommendations of the project geotechriical reports (Appendix A) and geotechnical recommendations made during the course of grading. After the removals were made, the removal areas flatter than 5:1 (horizontal to vertical) were scarified a minimum of 12 inches, moisture-conditioned as needed to obtain a near- optimum moisture content and compacted to a minimum 90 percent relative compaction, as determined by American Society for Testing and Materials (ASTM) Test Method D1557. The steeper natural hillsides were benched into competent material as fill was placed. Representative bottom elevations in the removal areas are shown on the As-graded Geotechnical Map (Plates I and 2). 2.2 Stability Fill Keys The stability fills were constructed to stabilize the exposed blocky claystone/siltstone and/or adverse geologic conditions present within the Santiago Formation. The stability fill keys were excavated a minimum of 3 to 5 feet below the toe-of-slope, a minimum of 15 feet to 20 feet wide with the key bottom angled at least 2 percent into-the-slope. The stability fill front cuts were excavated near vertical while the backcuts were excavated at an approximate 1:1 (horizontal to vertical) slope inclination. The stability fills were excavated at: 1) the southwest side of El Fuerte Street (Station Nos. 16+85 to 21+75; 2) north side of 4 -4- Leighton 971009-014 Gardenlane Way (Station Nos. 16+50 to 24+00); 3) south side of Gardenlane Way (Station Nos. 17+50 to 23+85), and 4) on the west side of Planning Area PA-13. The approximate locations of the stability fill keys are presented on the As-graded Geotechnical Map (Plates I and 2). 2.3 Fill Slope Keys Prior to the placement of fill slopes that were placed above natural and/or cut areas on the site, a fill slope key was constructed. The fill slope keys were excavated at least 2 feet into competent soil along the toe-of-slope and constructed approximately 15 feet wide with the key bottom angled a minimum of 2 percent into-the-slope. 2.4 Subdrains Canyon and stability fill subrains were placed under the observation of a representative of Leighton and Associates during the mass grading operations for the Bressi Ranch project. After the potentially. compressible material in the canyons were removed to competent material or when compacted fill was placed over competent material to obtain flow to a suitable outlet location, a subdrain was installed along the canyon bottom. The canyon subdrains consisted of a 6-inch diameter perforated pipe surrounded by a minimum of 9- cubic feet (per linear foot) of crushed 3/4-inch gravel wrapped in Mirafi 140N filter fabric. In addition to the canyon subdrains, subdrains were also installed along the bottom of the stability fill keys. The stability fill subrains consisted of a 4-inch diameter perforated pipe surrounded by a minimum of 3-cubic feet (per linear foot) of clean 3/4-inch gravel wrapped in Mirafi 140N filter fabric. The canyon and stability fill subdrains were placed with a minimum 1-percent fall (2-percent or 'greater where possible) to a suitable outlet location. The location of the subdrains placed during the mass grading operations for the project were surveyed by the project civil engineer. The subdrain locations presented on the As-graded Geotechnical Map (Plates I and 2). 2.5 Cut/Fill Transition Condition The sheet-graded pads of Planning Areas PA-13, PA-14, and PA-15 consist of both cut and fills. The cut/fill transition conditions on the sheet-graded pads were not mitigated, during the mass grading operations. Once thà site improvements on the pads of the planning areas are determined, specific recommendations concerning the cut/fill transition conditions can be provided. In general, the cut/fill transition conditions can be mitigated by the overexcavation of the cut portion of the pad or by designing deep foundations that extend through the fill. -5- Leighton 971009-014 2.6 Placement of Oversized Material During the mass grading operations of the Bressi Ranch project, a number of well cemented or concretionary beds where encountered within the Santiago Formation. Excavation of the cemented/concretionary beds or zones typically resulted in rock fragments ranging from less than 6 inches to greater than 4 feet in maximum dimension. In order to minimize difficult excavation of future utility trenches or foundations excavations, recommendations were made during the mass grading operations to place the oversized rock (generally defined as greater than 8 inches in diameter) below a depth of 5 to 10 feet below the sheet-graded finish grade elevation. While the contractor made their best effort to minimize the rock within the upper 5 to 10 feet of the sheet-graded finish grade surface, some oversized rock should be anticipated. In addition, cemented or concretionary beds should be anticipated at or below the finish grade surface in the cut areas and may result in the generation of additional oversized rock. Future fine grading of the sheet-graded pads may also result in generation of oversized rock if the existing grades are lowered more than 5 to 10 feet. 2.7 ExDansive Soil at Finish Grade Based on our geologic mapping and professional experience on other portions of the Bressi Ranch Project, low to very high expansive soils are present within Planning Areas PA-13, PA-14, and PA-15. The actual extent of expansive soils should be evaluated during future grading. Recommendations concerning these expansive soils are presented in Section 5.1.3. 2.8 Fill Placement and Compaction After the completion of the remedial grading removals, processing of the excavated areas, and/or installation of the subdrains, native soil was reused and placed as compacted fill. The native soil was generally spread in 4- to 8-inch loose lifts; moisture conditioned as needed to attain a near-optimum moisture content, and compacted. Field density test results performed during the grading operations indicated the fill soils were compacted t0 at least 90 or 95 percent of the maximum dry density in accordance with ASTM Test Method D1557. To mitigate post-construction settlement, the lower portions of the deep fill areas (i.e. areas were the fill soils are generally deeper than approximately 40 feet below the proposed finish grade elevations of the sheet-graded pads) were placed in accordance with the geotechnical recommendations relative to deep fills (Leighton, 2003c). In general, the fill soils below a depth of approximately 40 from the sheet-graded pad elevations were placed and compacted 4 -6- •'• Leighton 971009-014 to a minimum relative compaction of 95 percent relative compaction. Deep fill areas are present in Planning Area PA-13. Compaction of the fill soils was achieved by use of heavy-duty construction equipment (including rubber-tire compactors and 651 scrapers and 657 scrapers). Areas of fill in which field density tests indicated compactions less than the recommended relative compaction or where the soils exhibited nonuniformity or had field moisture contents less than approximately 2 to 3 percent. below the laboratory optimum moisture content, were reworked. The reworked areas were recompacted, and re-tested until the recommended minimum 90 or 95 percent relative compaction and near-optimum moisture content was achieved. 2.9 Field Density Testing Field density testing and observations were performed using the Nuclear-Gauge Method (ASTM Test Methods D2922 and D3017). The approximate test locations are shown on the As-graded Geotechnical Map (Plates 1 and 2). The results of the field density tests are summarized in Appendix B. The field density testing was performed in general accordance with the applicable ASTM Standards, the current standard of care in the industry, and the precision of the testing method itself. Variations in relative compaction should be expected from the results documented herein. 2.10 Laboratory Testing Laboratory maximum dry density tests of representative on-site soils were performed in general accordance with ASTM Test Method D1557. The test results are presented in Appendix C. Expansion potential and soluble sulfate content testing of the finish grade soils of the sheet-graded pads were not performed during the mass grading operations. However, the expansion potential of the anticipated finish grade soils (i.e. soils within approximately 5 feet of the existing ground surface) are assumed to be in the low to very high expansion potential range. Once final grades are reached, representative finish grade soils should be tested to determine the actual expansion potential of the soils. it -7- Leighton 971009-014 2.11 Graded Slopes Graded and natural slopes within the developed portion of the tract are considered grossly and surficially sthble from a geotechnical standpoint. Manufactured cut and fill slopes within the tract were surveyed by the civil engineer are understood to have been constructed with slope inclinations of 2:1 (horizontal to vertical) or flatter. 2.12 Settlement Monument Monitoring of Deep Fills Upon completion of the mass grading operations of Planning Areas PA-13, a total of two settlement monuments were placed in deep fill areas (i.e. fill areas generally greater than 40 feet in depth). The settlement monuments were initially surveyed shortly, after installation and at bi-monthly intervals thereafter. Based on our evaluation of the survey data obtained from the settlement monuments placed in Planning Area PA-13 of the Bressi Ranch project, it is our professional opinion that the primary settlement of the fill soils is essentially complete. Therefore, from a geotechnical standpoint, construction of the improvements in the deep fill area within Planning Area PA- 13 may begin. IL -8- '• ''":. Leighton / f 971009-014 3.0 ENGINEERING GEOLOGIC SUMMARY 3.1 As-graded Geologic Conditions The geologic or geotechnical conditions encountered during the mass grading operations of Planning Areas PA-13, PA-14, and PA-15 of the Bressi Ranch project were essentially as anticipated. A comprehensive summary of the geologic conditions (including geologic units, geologic structure, and faulting) is presented below. The as-graded geologic conditions are presented on the As-graded Geotechnical Map (Plates I and 2). 3.2 Geologic Units The geologic units encountered during the mass grading operations consisted of undocumented fill soils, topsoil, coihivium, alluvium, landslide deposits, and the Santiago Formation. Due to the potentially compressible nature of the undocumented fill, topsoil, colluvium, alluvium, landslide deposits, and weathered formational material, these soils were removed to competent material during the mass grading operations. The approximate limits of the as-graded geologic units encountered during the grading operations are presented on the As-Graded Geotechnical Map (Plates 1 and 2) and discussed (youngest to oldest) below. 3.2.1 Undocumented Fill Soils (Mao Symbol - AN) Undocumented fill soils were observed in a number of places on the site. The undocumented fills were generally associated with the grading of the onsite dirt roads, retention. basins, and prior farming activities. These fill soils ranged from approximately 1 to 5 feet in depth, and generally consist of dry to damp, loose or soft sand and clay. All existing undocumented fill located within the limits of grading were removed to competent formational material. 3.2.2 Topsoil (Unmapped) A relatively thin veneer of topsoil was removed from the majority of the site. The topsoil, as encountered, consisted predominately of a brown, damp to moist, loose, sandy clay and minor clayey to silty sand. The topsoil was generally massive; porous, and contained scattered roots and organics. Topsoil removal thickiiesses were on the.order I to 4 feet thick. During the grading operations, the topsoil was observed to have been removed within the limits of grading. it -9- . Leighton 971009-014 3.2.3 Alluvium/Colluvium, Undifferentiated Map Symbol (Oal/Ocol) Alluvium and colluvium was encountered during the mass grading in the canyons and on the lower portion of the hillsides on the site. As encountered, the alluvium and colluvium consisted of dark brown, moist, loose to stiff, clayey sand, sandy clay, and silty sand. Where encountered, the alluvium and colluvium was removed to competent material. Up to approximately 50 feet of alluvium and colluvium was removed during the mass grading operations. - 3.2.4 Landslide Deposits The approximate limits of competent landslide deposits left-in-place are presented on the As-Graded Geotechnical Maps (Plates 1 and 2). One of the landslide deposits encountered during the rough grading operations was completely removed to formational material. The landslide deposits included graben in-fill material (at the upper end and on the sides of the landslides), relatively undisturbed blocks of formational material (within the central portion of the landslide mass), and disturbed/weathered material and buried topsoil, colluvium and/or alluvium (around the lower flanks and the toe of the landslides). The landslide deposits generally consisted of moderately to heavily fractured silty sand and sandy clay. The landslide basal rupture surfaces on all of the landslides generally consisted of a paper-thin, planner and polished surface located within the• Santiago Formation. Geologic mapping during the mass grading and landslide removals indicated the landslides failed on slightly undulatory, very shallow dipping (2 to 7 degrees out-of-slope inclinations) planner and polished surfaces. Due to their compressible nature and potential instability, remedial measures were performed on the landslides and hillsides exposing adverse geologic conditions (i.e. clayseams or other weak beds, out-of-slope bedding, etc.) encountered during the rough grading operations within the graded limits of the site. The remedial grading measures included the construction of stability fills and/or removal of loose and compressible landslide material. The approximate limits of the landslide deposits after the remedial grading operations were completed are presented on the as-graded geotechnical map. 4 -10- Leighton -e j 971009-014 3.2.5 Santiago Formation (Man Symbol-Is) The Tertiary-aged Santiago Formation, as encountered during the mass grading operations, consisted primarily of massively bedded sandstones and claystones/siltstones. The sandstone generally consisted of orange-brown (iron -' oxide staining) to light brown, damp to moist, dense to very dense, silty very fine to medium grained sandstone. The siltstones and claystones were generally olive-green I to gray (unweathered), damp to moist, stiff to hard, moderately weathered, and occasionally fractured and moderately sheared. Several well-cemented fossiliferous sandstone beds were encountered during the mass grading operations. Medium to high expansive soils are present at the existing finish grade elevation of the sheet- graded pads within portions of Planning Areas PA- 14 and PA- 15. 3.3 Geologic Structure The general structure of the formational material appears to be near horizontal. Based on our geologic mapping during the mass grading operations, bedding within the Santiago Formation generally exhibited somewhat variable bedding with strikes ranging from northwest to northeast and dips typically 2 to 9 degrees (or less) to the southeast and northwest. Locally, cross bedding was observed with dips steeper than 15 degrees. Jointing on-site was observed to be very variable, but predominantly trended subparallel to the existing slopes. Jointing dips were found to be generally moderately to steeply dipping. Jointing was mainly encountered in the upper portion of the bedrock becoming less pronounced with depth. Randomly oriented shears were encountered in the Santiago Formation claystone and siltstone units. Numerous wide, diffuse zones of shearing, as well as more well-defined zones, were encountered in the bedrock, and are thought to be the result of regional tectonic shearing of the relatively stiff and unyielding siltstone and claystone. 3.4 Faulting and Seismici Our discussion of faults on the site is prefaced with a discussion of California legislation and state policies concerning the classification and land-use criteria associated with faults. By definition of the California Mining and Geolàgy Board, an active fault is a fault that has had surface displacement within Holocene time (about the last 11,000 years). The State Geologist has defined a potentially active fault as any fault considered to have been active during Quaternary time (last 1,600,000 years) but that has not been proven to be active or inactive. This definition is used in delineating Fault-Rupture Hazard Zones as mandated by the Aiquist-Priolo Earthquake Fault Zoning Act of 1972 and as most recently revised in 1997. The intent of this act is to assure that unwise urban development does not occur it -11- Leighton 971009-014 across the traces of active faults. Based on our review of the Fault-Rupture Hazard.Zones, the site is not located within any Fault-Rupture Hazard Zone as created by the Alquist- Priolo Act (Hart, 1997). San Diego, like the rest of southern California, is seismically active as a result of being located near the active margin between the North American and Pacific tectonic plates. The principal source of seismic activity is movement along the northwest-trending regional fault zones such as the San Andreas, San Jacinto and Elsinore Faults Zones, as well as along less active faults such as the Rose Canyon Fault Zone. As indicated in the Supplemental Geotechnical Report for the Bressi Ranch project (Leighton, 2001), there are no known major or active faults on or in the immediate vicinity of the site. Evidence of active faulting was not encountered during the mass grading operations. However, several minor inactive faults were encountered but are not considered a constraint to development of Planning Areas PA-13, PA-14, and PA-15. Geologic mapping of the onsite minor faults, where topsoil was encountered over the faults, indicated that the faults did not extend into or offset the topsoil, suggesting that the faults are not active. The nearest known active fault is the Rose Canyon Fault Zone, which is considered a Type B Seismic Source- based on the 1997 Uniform Building Code (UBC), is located approximately 7.0 miles (11.2 kilometers) west of the site. Because of the lack of known active faults on the site, the potential for surface rupture at the site is considered low. Shallow ground rupture due to shaking from distant seismic events is not considered a significant hazard, although it is a possibility at any site. Liquefaction and dynamic settlement of soils can be caused by strong vibratory motion due to earthquakes. Both research and historical data indicate that' loose, saturated, granular soils are susceptible to liquefaction and dynamic settlement. Liquefaction is typified by a loss of shear strength in the affected soil layer, thereby causing the soil to act as a viscous liquid. This effect may be manifested by excessive settlements and sand boils at the ground surface. The fill and formational materials underlying the site are not considered liquefiable due to their fine-grained nature, dense physical characteristics, and unsaturated condition. 3.5 Ground Water Perched ground water was encountered during the rough grading operations in the alluvial soils within the main drainages on the site. Since the alluvial soils were completely removed during the rough grading operations and subdrains installed in the canyon bottoms, groundwater conditions should not be a constraint to development. Based on the site- specific as-graded geotechnical conditions and our geotechnical analysis during site grading, the geotechnical consultant has analyzed conditions that may result in ground water seepage 4 -12- Leighton 971009-014 and appropriate recommendations, if necessary, have been made. However, unanticipated seepage or ground water conditions may occur after the completion of grading and establishment of site irrigation and landscaping. If these conditions should occur, steps to mitigate the seepage should be made on a case-by-case basis. -13- 5 Leighton 971009-014 4.0 CONCLUSIONS 4.1 General The mass grading operations for Planning Areas PA-13, PA-14, and PA-15 of the Bressi Ranch project were performed in general accordance with the project geotechnical reports (Appendix A), geotechnical recommendations made during grading, and the City of Carlsbad requirements. It is our professional opinion that the subject planning areas are suitable for their intended use provided the recommendations. included herein and in the project geotechnical report are incorporated into the design and construction of the structures and associated improvements. The following is a summary of our conclusions concerning the mass grading of Planning Areas PA-13, PA-14, and PA- 15. 4.2 Summary of Conclusions Geotechnical conditions encountered during mass grading were generally as anticipated. . Site preparation and removals were geotechnicaily observed. The geologic units encountered during the mass grading of the site consisted of undocumented fill soils, topsoil, colluvium, alluvium, landslide deposits, and the Santiago Formation. Unsuitable undocumented fill soils, topsoil, colluvium, alluvium, landslide deposits, and weathered formational material were removed to competent material within the limits of grading. Stability fills were constructed to improve the, gross stability of the cut slopes exposing fractured and blocky formational material and/or adverse geologic conditions on the site. The stability fill keys were excavated in accordance with the project geotechnical recommendations. Subdrains were placed in the bottom of the canyon bottoms and along the heel of the stability fill keys. Fill slopes located above natural ground or cut areas were constructed with a fill slope key. All keys were excavated to a minimum 15 feet wide, at least 2 feet into competent material along the toe-of-slope with the key inclined 2 percent into the slope. .' Fill soils were derived from onsite soils. Field density testing indicated that the fill soils were placed and compacted to at least 90 or 95 percent relative compaction (based on ASTM Test Method D1557) and near-optimum moisture contents in accordance with 4 -14- Leighton' 971009-014 the recommendations of Leighton and Associates and the requirements of the City of Carlsbad. The results of the field density tests are summarized in Appendix B. To mitigate post-construction settlement, deep fills (i.e. areas were the fill soils are generally deeper than approximately 40 feet below the finish grade elevations of the sheet-graded pads) were placed at a minimum relative compaction of 95 percent relative compaction. Deep fill areas are present within Planning Area PA- 13. The cut/fill transition conditions present within Planning Areas PA-14 and PA-15 were not mitigated during the mass grading operations. Cut/fill transition conditions present within the limits of the proposed buildings should be mitigated by the overexcavation of the cut portion of the building pad or by special foundation design. Oversized rock generated during the grading operations was placed at least 5 feet below finish grade elevations. Although, some oversize rock may be encountered with 5 feet of fill and cut areas. Based on our evaluation of the survey data obtained from the settlement monuments placed in Planning Area PA-13 of the Bressi Ranch project, it is our professional opinion that the primary settlement of the fill soils is essentially complete. Therefore, from a geotechnical standpoint, construction of the improvements in the deep fill area within Planning Area PA-13 may begin. Consequently, survey readings of the monuments inPA-13 can be discontinued and the monuments may be removed. Ground water seepage conditions were encountered during the mass grading operations of Planning Areas PA-13, PA-14, and PA-15 but are not considered constraints to development. No evidence of active faulting was encountered during site mass grading. However, minor inactive faults were encountered within Planning Areas PA-13, PA-14, and PA- 15. Due to the dense nature of the onsite soils, it is our professional opinion that the liquefaction hazard at the site is considered low. The expansion potential of the finish grade soils of the sheet-graded pads were not tested. However, we anticipate the onsite soils posses low to high expansion potentials. Highly expansive soils should not be placed as fill or left as cut within the limits of the proposed buildings or other movement sensitive improvements unless special foundation design considerations are implemented. Once final grades are reached, representative finish grade soils should be tested to determine the actual expansion potential of the soils. 4 -15- Leighton 971009-014 The potential for soluble sulfate attack (on Type I/TI cement) of the finish grade soils was not tested. We anticipate that the onsite soils may possess negligible to severe soluble sulfate contents. Once final grades are reached, representative finish grade soils should be tested to determine the actual potential for soluble sulfate attack of the soils. It is our opinion that the slopes of the development possess a static factor of safety of at least 1.5 to resist deep-seated failure (under normal irrigation/precipitation patterns), provided the recommendations in the project geotechnical reports are incorporated into the post-grading, construction and post-construction phases of site development. 4 -16- Leighton 971009-014 5.0 RECOMMENDATIONS 5.1 Earthwork We anticipate that future earthwork at the site will consist of site preparation, rough or fine grading, utility trench excavation and backfill, retaining wall backfill, and street/driveway and parking area pavement section preparation and compaction. We recommend that the earthwork on site be performed in accordance with the following recommendations, the General Earthwork and Grading Specifications for Rough Grading included in Appendix D, and the City of Carlsbad grading requirements. In case of conflict, the following recommendations shall supersede those in Appendix D. The contract between the developer and earthwork contractor should be worded. such that it is the responsibility of the contractor to place the fill properly and in accordance with the recommendations of this report and the specifications in Appendix D, notwithstanding the testing and observation of the geotechnical consultant. 5.1.1 Site Preoaration During future grading, the areas to receive structural fill or engineered structures should be cleared of surface obstructions, potentially compressible material (such as desiccated fill soils or weathered formational material), and stripped of vegetation. Vegetation and debris should be removed and properly disposed of off site. Holes resulting from removal of buried obstructions that extend below finish site grades should be replaced with suitable compacted fill material. Areas to receive fill and/or other surface improvements should be scarified to a minimum depth of 12 inches, brought to optimum moisture condition, and recompacted to at least 90 percent relative compaction (based on ASTM Test Method D1557). If the length of time between the completion of grading and the construction of the development is longer than six months, we recommend that the building pads be evaluated by the geotechnical consultant and, if needed, the finish grade soils on the building pads should be scarified a minimum of 12 inches, moisture-conditioned to optimum moisture-content and recompacted to a minimum 90 percent relative compaction (based on ASTM Test Method D1557). 5.1.2 Mitigation of Cut/Fill Transition Conditions In order to reduce the potential for differential settlement of the proposed buildings in areas of cut/fill transitions, we recommend the entire cut portion of the building pad be overexcavated and replaced with properly compacted fill. The extent and depth of the cut/fill transition condition overexcavation should be made based on 4 -17- Leighton 971009-014 the proposed building foundation design. At a minimum, it should extend lateraily.at least 10 feet beyond the building perimeter or footprint. In order to minimize perched ground water conditions in the overexcavation, we recommend that the overexcavation bottom be tilted a minimum of 2-percent toward the fill side of the building pad. Additional or revised recommendations may be warranted based on the configuration and size of the proposed buildings. If the majority of the proposed building is located on cut, the fill soils beneath the building may be removed and recompacted to a minimum 95 percent relative compaction or a deep foundation system founded completely on formational material may be utilized. 5.1.3 Mitigation of High Expansive Soils at Finish Grade Due to the anticipated high expansion potential of the claystones and siltstones present at finish grade within portions of the site, we recommend that the high expansive soil-be removed below the planned finish grade of the proposed buildings and other movement sensitive improvements. If these expansive soils are removed, the removal depth should be a minimum of 5 feet below the proposed finish grade elevation or until lower expansive sandy soils are encountered. We also recommend that the excavation bottom be tilted a minimum of 2-percent toward the fill side of the building pad or toward the street/driveway in order to minimize perched ground water conditions. The resulting excavation should be replaced with properly compacted fill possessing a lower expansion potential. The actual location of the claystones and siltstones at or near finish grade at the site should be evaluated during future grading. 5.1.4 Excavations Excavations of the on-site materials may generally be accomplished with conventional heavy-duty earthwork equipment. It is not anticipated that blasting will be required or that significant quantities of oversized rock (i.e. rock with maximum dimensions greater than 8 inches) will be generated during future grading. However, localized cemented zones within the cut areas and oversized rock placed within the compacted fill may be encountered on the site that may require heavy ripping and/or removal. It should be anticipated that excavations deeper than 5. to 10 feet from the mass-graded finish grade elevations in the fill areas ffl encounter oversized rock. If oversized rock is encountered, it should be placed in accordance with the recommendations presented in Appendix D, hauled offsite, or placed in non- structural or landscape areas. -18- Leighton 971009-014 Due to the relatively dense characteristics of the on-site soils, temporary excavations such as utility trenches in the on-site soils should remain stable for the period required to construct the utility, provided they are constructed and monitored in accordance with OSHA- requirements. 5.1.5 Fill Placement and Compaction The on-site soils are generally suitable for use as compacted fill provided they are free or organic material, debris, and rock fragments larger than 8 inches in maximum dimension. We do not recommend that high or very high expansive soils be utilized as fill for the building pads or as retaining wall backfill. All fill soils should be brought to 2-percent over the optimum moisture content and compacted in uniform lifts to at least 90 percent relative compaction based on the laboratory maximum dry density (ASTM Test Method D1557). The optimum lift thickness required to produce a uniformly compacted fill will depend on the type and size of compaction equipment used. in general, fill should be placed in lifts not exceeding 8 inches in compacted thickness. Placement and compaction of fill should be performed in general accordance with Appendix D, the current City of Carlsbad grading ordinances, sound construction practices, and the geotechnical recommendations presented herein. 5.2 Commercial Foundation Design Considerations The foundations and slabs for the anticipated commercial and/or retail buildings within the Bressi Ranch project should be designed in accordance with structural considerations and the following preliminary recommendations. These preliminary recommendations assume that the soils encountered within 5 feet of finish pad grade will have a very low to low potential for expansion per 1997 UBC Standard 18-1. If moderate or highly expansive soils are encountered within 5 feet of the proposed finish grade elevations during site grading, these expansive soils should be removed and replaced with very low to low expansive soils. If replacement of the expansive soils is not feasible, additional foundation design will be necessary. The proposed commercial buildings may be supported by conventional, continuous or isolated spread. footings. Footings should extend a minimum of 24 inches beneath the lowest adjacent soil grade. At these depths, footings may be designed for a maximum allowable bearing pressure of 2,500 pounds per square foot (psf) if founded in properly compacted fill soils or formational material. An allowable capacity increase of 500 psf for every 6 inches of additional embedment may be used to a maximum of 3,500 psf. The allowable pressures may be increased by one-third when considering loads of short duration such as wind or seismic forces. The minimum recommended width of footings is 4* -i- Leighton 971009-014 18 inches for continuous footings and 24 inches for square or round footings. Footings should be designed in accordance with the structural engineer's requirements and have a minimum reinforcement of four No. 5 reinforcing bars (two top and two bottom). The slab-on-grade foundation should be at least 5 inches thick and be reinforced with No. 4 rebars 18 inches on center or No. 5 rebars at 24 inches on center, each way. All reinforcing should be placed at mid-height in the slab. Slabs should be underlain by a 2- inch layer of clean sand (sand equivalent greater than 30), which is in-turn underlain by a minimum 1 O-mil plastic sheeting (moisture barrier) and an additional 2 inches of clean sand. We recommend that control joints be provided across the slab at appropriate intervals as designed by the project architect. The potential for slab cracking may be reduced by careful control of water/cement ratios. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to minimize cracking of slabs. We recommend that a slipsheet (or equivalent) be utilized if grouted tile, marble tile, or other crack-sensitive floor covering is planned directly on concrete slabs. All slabs should be designed in accordance with structural considerations. If heavy vehicle or equipment loading is proposed for the slabs, greater thicknesses and increased reinforcing may be required as determined by the structural engineer. 5.2.1 Moisture Conditioning The slab subgrade soils underlying the foundation systems of the proposed structures should be presoaked in accordance with the recommendations presented in Table 1 prior to placement of the moisture barrier and slab concrete. The subgrade soil moisture content should be checked by a representative of Leighton and Associates prior to slab construction. -20- Leighton 971009-014 Table 1 Presaturation Recommendations Based on Finish Grade Soil Expansion Potential Expansion Potential (per UBC 18-I-B) Very Low Low Medium 1 High Presaturation Criteria (0-20), (21-50) (51-90) 1 (91-130) Minimum Presoaking Depth 6 12 18 24 (in inches) Minimum Near optimum 1.2 times 1.2 times 1.3 times Recommended moisture optimum optimum optimum Moisture Content I moisture moisture moisture Presoaking or moisture conditioning may be achieved in a number of ways, but based on our professional experience, we have found that minimizing the moisture loss of pads that have been completed (by periodic wetting to keep the upper portion of the pad from drying out) and/or berming the lot and flooding if for a short period of time (days to a few weeks) are some of the more efficient ways to meet the presoaking requirements. If flooding is performed, a couple of days to let the upper portion of the pad dry out and form a crust so equipment can be utilized should be anticipated. 5.2.2 Seismic Design Parameters The site lies within Seismic Zone 4, as defined in the UBC, 1997 edition. The nearest known active fault is the Rose Canyon Fault Zone, which is considered a Type B Seismic Source (per. 1997 UBC criteria), is located approximately 7.0 miles (or 11.2 kilometers) west of the site The closest Type A Seismic Source is the Julian segment of the Elsinore Fault Zone, which is located approximately 23.5 miles (or 38 kilometers) east of the site. The following data should be considered for the seismic analysis of the proposed structures: . Causative Fault: Rose Canyon Fault Zone Maximum Magnitude: 7.2 . Seismic Source Type: B . Seismic Zone Factor: 0.40 -21- Leighton 971009-014 Is Soil Profile Type: Sc Near Source Factors: Na= 1.0/Nv = 1.0 5.2.3 Foundation Setback We recommend a minimum horizontal setback distance from the face of slopes or adjacent retaining walls for all structural foundations, footings, and other settlement- sensitive structures as indicated on Table 2. This distance is measured from the outside bottom edge of the footing, horizontally to the slope face and is based on the slope height and type of soil. However, the foundation setback distance may be revised by the geotechnical consultant on a case-by-case basis if the geotechnical conditions are different than anticipated. Table 2 Minimum Foundation Setback from Descending Slope Faces Slope Height Minimum Recommended Foundation Setback Less than 5 feet 5 feet 5to15feet 7feet 15 to 30 feet 10 feet Greater than 30 feet 20 feet Please note that the soils within the structural setback area possess poor lateral stability, and improvements (such as retaining walls, sidewalks, fences, pavements, etc.) constructed within this setback area may be subject to lateral movement and/or differential settlement. Potential distress to such improvements may be mitigated by providing a deepened footing or a pier and grade beam foundation system to support the improvement. The deepened footing should meet the setback as described above. 4 -22- Leighton 971009-014 5.2.4 Anticipated Settlement Settlement is anticipated to occur at varying times over the life of the project. Short- term settlement typically occurs upon application of the foundation loads and is essentially completed within the construction period. Long-term (hydroconsolidation) settlement typically occurs in deep fills upon additional water infiltration into the fill soils (even in properly compacted fill soils and even with subdrains provided). This settlement typically occurs over many years. Long-term settlement values and the affects on the foundations should be evaluated after the site is graded and the actual fill thicknesses beneath the proposed foundations known. However, for preliminary planning purposes, total future settlement is expected to be order of 1 to 2 inches and differential settlement is estimated to be on the order of 1/2 inch in 25 feet. 5.3 Lateral Earth Pressures The recommended lateral pressures for the onsite very low to low expansive soil (expansion index less than 50 per UBC Table 18-I-B) or medium expansive soil (expansion index between 51 and 90 per UBC Table 18-I-B) and level or sloping backfill are presented on Table 3. High to very high expansive soils (having an expansion potential greater than 91 per UBC Table 18-I-B) should not be used as backfill soils on the site. Table 3 Lateral Earth Pressures Conditions Equivalent Fluid Weight (pcf) Very Low to Low Expansive Soils • Medium Expansive Soils Expansion Index less than 50 Expansion Index between 51 and 90 Level 2:1 Slope Level 2:1 Slope Active 35 55 60 70 At-Rest 55 65 70 80. Passive 350 150 350 150 -23- Leighton 971009-014 Embedded structural walls should be designed for lateral earth pressures exerted on them. The magnitude of these pressures depends on the amount of deformation that the wall can yield under load. If the wall can yield enough to mobilize the full shear strength of the soil, it can be designed for "active" pressure. If the wall cannot yield under the applied load, the shear strength of the soil cannot be mobilized and the earth pressure will be higher. Such walls should be designed for "at rest" conditions. If a structure moves toward the soils, the resulting resistance developed by the soil is the "passive" resistance. The above noted passive resistance assumes an appropriate setback per Section 5.2.3. For design purposes, the recommended equivalent fluid pressure for each case for walls founded above the static ground water and backfllled with soils of very low to low expansion potential or medium expansion potential is provided on Table 3. The equivalent fluid pressure values assume free-draining conditions. If conditions other than those assumed above are anticipated, the equivalent fluid pressures values should be provided on an individual-case basis by the geotechnical engineer. The geotechnical and structural engineer should evaluate surcharge-loading effects from the adjacent structures. All retaining wall structures should be provided with appropriate drainage and appropriately waterproofed. The outlet pipe should be sloped to drain to a suitable outlet. Typical wall drainage design is illustrated in Appendix D. For sliding resistance, the friction coefficient of 0.35 may be used at the concrete and soil interface. In combining the total lateral resistance, the passive pressure or the frictional resistance should be reduced by 50 percent. Wall footings should be designed in accordance with structural considerations. The passive resistance value may be increased by one-third when considering loads of short duration including wind or seismic loads. The horizontal distance between foundation elements providing passive resistance should be minimum of three times the depth of the elements to allow full development of these passive pressures. The total depth of retained earth for the design of cantilever walls should be the vertical th distance below e ground surface measured at the wall face for stem design or measured at the heel of the footing for overturning and sliding. All wall backcuts should be made in accordance with the current OSHA requirements. The granular and native backfill soils should be compacted to at least 90 percent relative compaction (based on ASTM Test Method D1557). The granular fill should extend horizontally to a minimum distance equal to one-half the wall height behind the walls. The walls should be constructed and backfllled as soon as possible after backcut excavations. Prolonged exposure of backcut slopes may result in some localized slope instability. Foundations for retaining walls in competent formational soils or properly compacted fill should be embedded at least 24 inches below lowest adjacent grade. At this depth, an allowable bearing capacity of 2,000 psf may be assumed. 4 -24- Leighton 971009-014 5.4 Fences and Freestanding Walls Footings for freestanding walls should be founded a minimum of 24 inches below lowest adjacent grade. To reduce the potential for unsightly cracks in freestanding walls, we recommend inclusion of construction joints at a maximum of 15-foot intervals. This spacing may be altered in accordance with the recommendations of the structural engineer, based on wall reinforcement details. Our experience on similar sites in older developments indicates that many walls on shallow foundations near the top-of-slopes tend to tilt excessively over time as a result of slope creep. If the effects of slope creep on top-of-slope walls are not deemed acceptable, one or a combination of the options provided in the following paragraphs should be utilized in the design of such structures, based on the desired level of mitigation of creep-' related effects on them. A relatively inexpensive option to address creep related problems in top-of-slope walls and fences is to allow some degree of creep damage and design the structures so that tilting or cracking will be less visually obvious, or such that they may be economically repaired or replaced. If, however, a better degree of creep mitigation is desired, the walls and fences may be provided with the deepened footings to met the foundation setback criteria laid out in Figure 18-I-1 of the UBC, 1997 edition, or these structures may be constructed to accommodate potential movement. Under certain circumstances, an effective solution to minimize the effects of creep on top- of-slope walls and fences is to support these structures on a pier-and-grade-beam system. The piers normally consist of minimum 12-inch diameter cast-in-place caissons spaced at a maximum of 8 feet on center, and connected together by a minimum 12-inch-thick grade beam at a shallow depth. The piers are typically at least 10 feet deep for medium or high expansive soil. The steel reinforcement for the system should be designed with consideration of wall/fence type and loading. Walls or fences aligned essentially perpendicular to the top of the slope are normally supported on the pier-and-grade-beam system for at least that part of the wall that is within 15 feet from the top-of-slope. Caisson support is recommended for all top-of-slope walls where slopes are greater than 10 feet in height and/or the soil on and adjacent to the slope consists of high to very high expansive soils. 5.5 Geochemical Considerations Geochemical screening of the onsite soils was not performed as part of our study. However, the results of our limited testing and our professional knowledge of similar soils in other portions of the Bressi Ranch project, indicates that concrete in contact with the on-site soils should be designed in accordance with the "severe" category of Table 19A-A-4 of the 2001 California Building Code. In addition, the onsite soils are 1 -25- Leighton I 971009-014 anticipated to have a corrosive environment for buried metal pipes or uncoated metal conduits. Laboratory testing should be performed on the soils placed at or near finish grade after completion of site grading to ascertain the actual corrosivity characteristics. 5.6 Subdrain Outlet Maintenance The approximate location of the subdrains and subdrain outlets constructed during the mass grading operations are identified on the As-Graded Geotechnical Map (Plates 1 and 2). All subdraiñ outlets should be periodically cleared of soil cover or other potential blockage that may have occurred since initial subdrain construction. In open space areas, it is recommended that the Property Owner or Management Company further maintain these outlets, as well as retaining wall drainage outlets to prevent further blockage. 5.7 Settlement Monitoring of Deep Fills Based on our evaluation of the survey data obtained from the settlement monuments placed in Planning Area PA-13 of the Bressi Ranch projeèt, it is our professional opinion that the primary settlement of the fill soils is essentially complete. Therefore, from a geotechnical standpoint, construction of the improvements in the deep fill area within Planning Area PA-13 may begin. Consequently, survey readings of the monuments in PA-13 can be discontinued and the monuments may be removed. Secondary consolidation settlement of the fill soil may continue; however, future settlements are expected to be less than 2 inches. 5.8 Preliminary Pavement Design The appropriate Asphalt Concrete (AC) and Class 2 aggregate base (AB) pavement section will depend on the type of subgrade soil, shear strength, traffic load, and planned pavement life. Since an evaluation-of the actual subgrade soils cannot be made at this time, we have assumed an R-value of 12 and Traffic Indexes (TI) of 5.0, 6.0 and 7.0. The pavement sections presented on Table 4 are to be used for preliminary planning purposes only. Final pavement designs should be completed in accordance with the City of Carlsbad design criteria after R-value tests have been performed on the actual subgrade materials. it -26- Leighton I 971009-014 Table 4 Preliminary Pavement Section Designs Traffic Index Assumed R-Value Preliminary Pavement Section 5.0 12 4 inches AC over 6 inches Class 2 Aggregate Base 6.0 12 4 inches AC over 12 inches Class 2 Aggregate Base 7.0 12 4 inches AC over 14 inches Class 2 Aggregate Base Asphalt Concrete (AC) and Class 2 aggregate base should conform to and be placed in accordance with the latest revision of California Department of Transportation Standard Specifications. Prior to placing the pavement section, the subgrade soils should have a relative compaction of at least 95 percent to a minimum depth of 12 inches (based on ASTM Test Method D1557). Aggregate Base should be compacted to a minimum of 95 percent relative compaction (based on ASTM Test Method D1557) prior to placement of the AC. If pavement areas are adjacent to heavily watered landscaping areas, we recommend some measures of moisture control be taken to prevent the subgrade soils from becoming saturated. It is recommended that the concrete curbing, separating the landscaping area from the pavement, extend below the aggregate base to help seal the ends of the sections where heavy landscape watering may have access to the aggregate base. Concrete swales should be designed if asphalt pavement is used for drainage of surface waters. 5.9 Control of Surface Water and Drainage Surface drainage should be carefully taken into consideration during precise grading, landscaping, and building construction. Positive drainage (e.g., roof gutters, downspouts, area drain, etc.) should be provided to direct surface water away from structures and towards the street or suitable drainage devices. Ponding of water adjacent to structures should be avoided; roof gutters, downspouts, and area drains should be aligned so as to transport surface water to a minimum distance of 5 feet away from structures. The performance of structural foundations is dependent upon maintaining adequate surface drainage away from structures. Water should be transported off the site in approved drainage devices or unobstructed swales. We recommend that the minimum flow gradient for the drainage be 1-percent for area drains and paved drainage swales; and 2-percent for unpaved drainage swales. We .4 -27- Leighton I 971009-014 recommend that where structures will be located within 5 feet of a proposed drainage swale, the surface drainage adjacent to the structures be accomplished with a gradient of at least 3-1/2 percent away from the structure for a minimum horizontal distance of 3 feet. Drainage should be further maintained by a swale or drainage path at a gradient of at least 1-percent for area drains and paved drainage swales and 2-percent for unpaved drainage swales• to a suitable collection device (i.e. area drain, street gutter, etc.). We also recommend that structural footings within 4 feet of the drainage swale flowline be deepened so that the bottom of the footing is at least 12 inches below the flow-line of the drainage swale. In places where the prospect of maintaining the minimum recommended gradient for the drainage swales and the construction of additional area drains is not feasible, provisions for specific recommendations may be necessary, outlining the importance of maintaining positive drainage. The impact of heavy irrigation or inadequate runoff gradient can create perched water conditions, resulting in seepage or shallow groundwater conditions where previously none existed. Maintaining adequate surface drainage and controlled irrigation will significantly reduce the potential for nuisance-type moisture problems. To reduce differential earth movements (such as heaving and shrinkage due to the change in moisture content of foundation soils, which may cause distress to a structure or improvement), the moisture content of the soils surrounding the structure should be kept as relatively constant as possible. All area drain inlets should be maintained and kept clear of debris in order to function properly. Rerouting of site drainage patterns and/or installation of area drains should be performed, if necessary. A qualified civil engineer or a landscape architect should be consulted prior to rerouting of drainage. 5.10 SloDe Maintenance Guidelines It is the responsibility of the owner to maintain the slopes, including adequate 'planting, proper irrigation and maintenance, and repair of faulty irrigation systems. To reduce the potential for erosion and slumping of graded slopes, all slopes should be planted with ground cover, shrubs, and plants that develop dense, deep root structures and require minimal irrigation. Slope planting should be carried out as soon as practical upon completion of grading. Surface-water runoff and standing water at the top-of-slopes should be avoided. Oversteepening of slopes should be avoided during construction activities and landscaping. Maintenance of proper lot drainage, undertaking Of property improvements in accordance with sound engineering practices, and proper maintenance of vegetation, including regular slope irrigation, should be performed. Slope irrigation sprinklers should be adjusted to provide maximum uniform coverage with minimal of water usage and overlap. Overwatering and consequent runoff and ground saturation should be avoided. If automatic sprinklers systems are installed, their use must be adjusted to account for rainfall conditions. it -28- Leighton 971009-014 Trenches excavated on a slope face for any purpose should be properly backfihled and compacted in order to obtain a minimum of 90 percent relative compaction, in accordance with ASTM Test Method D1557. Observation/testing and acceptanceby the geotechnical consultant during trench backfill is recommended. A rodent-control program should be established and maintained. Prior to planting, recently graded slopes should be temporarily protected against erosion resulting from rainfall, by the implementing slope protection measures such as polymer covering, jute mesh, etc. 5.11 Landscaping and Post-Construction Landscaping and post-construction practices carried out by the owner(s) and their representative bodies exert significant influences on the integrity of structures founded on expansive soils. Improper landscaping and post-construction practices, which are beyond the control of the geotechnical engineer, are frequently the primary cause of distress to these structures. Recommendations for proper landscaping and post-construction practices are provided in the following paragraphs within this section. Adhering to these recommendations will help in minimizing distress due to expansive soils, and in ensuring that such effects are limited to cosmetic damages, without compromising the overall integrity of structures. Initial landscaping should be done on all sides adjacent to the foundation of a structure, and adequate measures should be taken to ensure drainage of water away from the foundation. If larger, shade providing trees are desired, such trees should be planted away from structures (at a minimum distance equal to half the mature height of the tree) in order to prevent penetration of the tree roots beneath the foundation of the structure. Locating planters adjacent to buildings or structures should be avoided as much as possible. If planters are utilized in these locations, they should be properly designed so as to prevent fluctuations in the moisture content of subgrade soils. Planting areas at grade should be provided with appropriate positive drainage. Wherever possible, exposed soil areas should be above paved grades. Planters should not be depressed below adjacent paved grades unless provisions for drainage, such as catch basins and drains, are made. Adequate drainage gradients, devices, and curbing should be provided to prevent runoff from adjacent pavement or walks into planting areas. Watering should be done in a uniform, systematic manner as equally as possible on all sides of the foundation, to keep the soil moist. Irrigation methods should promote uniformity of moisture in planters and beneath adjacent concrete flatwork. Overwatering and underwatering of landscape areas must be avoided. Areas of soil that do no have ground cover may require more moisture, as they are more susceptible to evaporation. Ponding or trapping of water in localized areas adjacent to the foundations can cause differential moisture levels in subsurface soils and should, therefore, not be allowed. Trees located within a distance of 20 feet of foundations would require more water in periods of extreme -29- Leighton 971009-014 drought, and in some cases, a root injection system may be required to maintain moisture equilibrium. During extreme hot and dry periods, close observations should be carried out around foundations to ensure that adequate watering is being undertaken to prevent soil from separating or pulling back from the foundations. 5.12 Construction Observation and Testing Construction observation and testing should be performed by the geotechnical consultant during the remaining grading operations, future excavations and foundation or retaining wall construction on the graded portions of the site. Additionally, footing excavations should be observed and moisture determination tests of subgrade soils should be performed by the geotechnical consultant prior to the pouring of concrete. Foundation design plans should also be reviewed by the geotechnical consultant prior to excavations. .4 -30- Leighton 971009-014 6.0 LIMITATIONS The presence of our field representative at the• site was intended to provide the owner with professional advice, opinions, and recommendations based on observations of the contractor's work.

GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page lof6. LEIGHTON AND ASSOCIATES, INC. GENERAL EARTHWORK AND GRADING SPECIFICATIONSFOR ROUGH GRADING 1.0 General 1.1 Intent: These General Earthwork and Grading Specifications are for the grading and earthwork shown on the approved grading plan(s), and/or indicated in the geotechnical report(s). These Specifications are a part of the recommendations contained in the geotechnical report(s). In case of conflict, the specific recommendations in the geotechnical report shall supersede these more general Specifications. Observations of the earthwork by the project Geotechnical Consultant during the course of grading may result in new or revised recommendations that could supersede these specifications or the recommendations in the geotechnical report(s). 1.2 The Geotechnical Consultant of Record: Prior to commencement of work, the owner shall employ the Geotechnical Consultant of Record (Geotechnical Consultant). The Geotechnical Consultants shall be responsible for reviewing the approved geotechnical report(s) and accepting the adequacy of the preliminary geotechnical findings, conclusions, and recommendations prior to 'the commencement of the grading. Prior to commencement of grading, the Geotechnical Consultant shall review the "work plan" prepared by the Earthwork Contractor (Contractor) and schedule sufficient personnel to perform the appropriate level of observation, mapping, and compaction testing. During the grading and earthwork operations, the Geotechnical Consultant shall observe, map, and document the subsurface exposures to verify the geotechnical design assumptions. If the observed conditions are found to be significantly different than the interpreted assumptions during the design phase, the Geotechnical Consultant shall inform the owner, recommend appropriate changes in design to accommodate the observed conditions, and notify the review agency where required. Subsurface areas to be geotechnically observed, mapped, elevations recorded, and/or tested include natural ground after it has been cleared for receiving fill but before fill is placed, bottoms of all "remedial removal" areas, all key bottoms, and benches made on sloping ground to receive fill. The Geotechnical Consultant shall observe the moisture-conditioningand processing of the subgrade and fill materials and perform relative compaction testing of fill to determine the attained level of compaction. The Geotechnical Consultant shall provide the test results to the owner and the Contractor on a routine and frequent basis. I 3030.1094 Leighton and Associates, Inc. GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page 2 of 6 1.3 The Earthwork Contractor: The Earthwork Contractor (Contractor) shall be qualified, experienced, and knowledgeable in earthwork logistics, preparation and processing of ground to receive fill, moisture-conditioning and processing of fill, and compacting fill. The Contractor shall review and accept the plans, geotechnical report(s), and these Specifications prior to commencement of grading. The Contractor shall be solely responsible for performing the grading in accordance with the plans and specifications. The Contractor shall prepare and submit to the owner and the Geotechnical Consultant a work plan that indicates the sequence of earthwork grading, the number of "spfeads' of work and the estimated quantities of daily earthwork contemplated for the site prior to commencement of grading. The Contractor shall inform the owner and the Geotechnical Consultant of changes in work schedules and updates to the work plan at least 24 hours in advance of such changes so that appropriate observations and tests can be planned and accomplished. The Contractor shall not assume that the Geotechnical Consultant is aware of all grading operations. The Contractor shall have the sole responsibility to provide adequate equipment and methods to accomplish the earthwork in accordance with the applicable grading codes and agency ordinances, these. Specifications, and the recommendations in the approved geotechnical report(s) and grading plan(s). If, in the opinion of the Geotechnical Consultant, unsatisfactory conditions, such as unsuitable soil, improper moisture condition, inadequate compaction, insufficient buttress key size, adverse weather, etc., are resulting in a quality of work less than required in these specifications, the Geotechnical Consultant shall reject the work.and may recommend to the owner that construction be stopped until the conditions are rectified. 2.0 Preparation of Areas to be Filled 2.1 Clearing and Grubbing: Vegetation, such as brush, grass, roots, and other deleterious material shall be sufficiently removed and properly disposed of in a method acceptable to the owner, governing agencies, and the Geotechnical Consultant. The Geotechnical Consultant shall evaluate the extent of these removals depending on specific site conditions. Earth fill material shall not contain more than 1 percent of organic materials (by volume). No fill lift shall contain more than 5 percent of organic matter. Nesting of the organic materials shall not be allowed. If potentially hazardous materials are encountered, the Contractor shall stop work in the affected area, and a hazardous material specialist shall be informed immediately for proper evaluation and handling of these materials prior to continuing to work in that area. As presently defined by the State of California, most refined petroleum products (gasoline, diesel fuel, motor oil, grease, coolant, etc.) have chemical constituents that are considered to be hazardous waste. As such, the indiscriminate dumping or spillage of these fluids onto the ground may constitute a misdemeanor, punishable by fines and/or imprisonment, and shall not be allowed. 3030.1094 Leighton and Associates, Inc. GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page 3 of 6 2.2 Processing: Existing ground that has been declared satisfactory for support of fill by the Geotechnical Consultant shall be scarified to a minimum depth of 6 inches. Existing ground that is not satisfactory shall be overexcavated as specified in the following section. Scarification shall continue until soils are broken down and free of large clay lumps or clods and the working surface is reasonably uniform, flat, and free of uneven features that would inhibit uniform compaction. 2.3 Overexcavation: In addition to removals and overexcavations recommended in the approved geotechnical report(s) and the grading plan, soft, loose, dry, saturated, spongy, organic-rich, highly fractured or otherwise unsuitable ground shall be overexcavated to competent ground as evaluated by the Geotechnical Consultant during grading. 2.4 Benching: Where fills are to-be placed on ground with slopes steeper than 5:1 (horizontal to vertical units), the ground shall be stepped or benched. Please see the Standard Details for a graphic illustration. The lowest bench or key shall be a minimum of 15 feet wide and at least 2 feet deep,. into competent material as evaluated by the Geotechnical Consultant. Other benches shall be excavated a minimum height of 4 feet into competent material or as otherwise recommended by the Geotechnical Consultant. Fill placed on ground sloping flatter than 5:1 shall also be benched or otherwise overexcavated to provide a flat subgrade for the fill. 2.5 Evaluation/Acceptance of Fill Areas: All areas to receive fill, including removal and processed areas, key bottoms, and benches, shall be observed, mapped, elevations recorded, and/or tested prior to being accepted by the Geotechnical Consultant as suitable to receive fill. The Contractor shall obtain a written acceptance from the Geotechnical Consultant prior to fill placement. A licensed surveyor shall provide the survey control for determining elevations of processed areas, keys, and benches. 3.0 Fill Material 3.1 General: Material to be used as fill shall be essentially free of organic matter and other deleterious substances evaluated and accepted by the Geotechnical Consultant prior to placement. Soils of poor quality, such as those with unacceptable gradation, high expansion potential, or low strength shall be placed in areas acceptable to the Geotechnical Consultantor mixed with other soils to achieve satisfactoryfihl material. 3.2 Oversize: Oversize material defined as rock, or other irreducible material with a maximum dimension greater than 8 inches, shall not be buried or placed in fill unless location, materials, and placement methods are specifically accepted by the Geotechnical Consultant. Placement operations shall be such that nesting of oversized material does not occur and such that oversize -material is completely surrounded by compacted or densified fill. Oversize material shall not be placed within 10 vertical feet of finish grade or within 2 feet of future utilities or underground construction. 30301094 Leighton and Associates, Inc. GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page 4 of 6 3.3 Import: If importing of fill material is required for grading, proposed import material shall meet the requirements of Section 3.1. The potential import source shall be given to the Geotechnical Consultant at least 48 hours (2 working days) before importing begins so that its suitability can be determined and appropriate tests performed. 4.0 Fill Placement and Compaction 4.1 Fill Layers: Approved fill material shall be placed in areas prepared to receive fill (per Section 3.0) in near-horizontal layers not exceeding 8 inches in loose thickness. The Geoteôhnical Consultant may accept thicker layers if testing indicates the grading procedures can adequately compact the thicker layers. Each layer shall be spread evenly and mixed thoroughly to attain relative uniformity of material-and moisture throughout. 4.2 Fill Moisture Conditioning: Fill soils shall be watered, dried back, blended, and/or mixed, as necessary to attain a relatively uniform moisture content at or slightly over optimum. Maximum density and optimum soil moisture content tests shall be performed in accordance with the American Society of Testing and Materials (ASTM Test Method D1557-91). 4.3 Compaction of Fill: After each layer has been moisture-conditioned, mixed, and evenly spread, it shall be uniformly compacted to not less than 90 percent of maximum dry density (ASTM Test Method 01557-91). Compaction equipment shall be adequately sized and be either specifically designed for soil compaction or of proven reliability to efficiently achieve the specified level of compaction with uniformity. 4.4 Compaction of Fill Slopes: In addition to normal compaction procedures specified above, compaction of slopes shall be accomplished by backrolling of slopes with sheepsfoot rollers at increments of 3 to 4 feet in fill elevation, or by other methods producing satisfactory results acceptable to the Geotechnical Consultant. Upon completion of grading, relative compaction of the fill, out to the slope face, shall be at least 90 percent of maximum density per ASTM Test Method D1557-91. 4.5 Compaction Testing: Field tests for:.moisture content and -relative compaction of the fill soils shall be performed by the Geotechnical Consultant. Location and frequency of tests shall be at the Consultanfs discretion based on field conditions encountered. Compaction test locations will not necessarily be selected on a random basis. Test locationsshall be selected to verify adequacy of compaction levels in areas that are judged to be prone to inadequate compaction (such as close to slope faces and at the fill/bedrock benches). 3030.1094 Leighton and Associates, Inc. GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page 5 of 6 4.6 Frequency of Compaction Testing: Tests shall betaken at intervals not exceeding 2 feet in vertical rise and/or 1,000 cubic yards of compacted fill soils embankment. In addition, as a guideline, at least one test shall be taken on slope faces for each 5,000 square feet of slope face and/or each 10 feet of vertical height of slope. The Contractor shall assure that fill construction is such that the testing schedule can be accomplished by the Geotechnical Consultant. The Contractor shall stop or slow down the earthwork construction if these minimum standards are not met. 4.7 Compaction Test Locations: The Geotechnical Consultant shall document the approximate elevation and horizontal coordinates of each- test location. The Contractor shall coordinate with the project surveyor to assure that sufficient grade stakes are established so that the Geotechnical Consultant can determine the test locations with sufficient accuracy. At a minimum, two grade stakes within a horizontal distance of 100 feet and vertically less than 5 feet apart from potential test locations shall be provided. 5.0 Subdrain Installation Subdrain systems shall be installed in accordance with the approved geotechnical report(s), the grading plan, and the Standard Details. The Geotechnical Consultant-may recommend additional subdrains and/or changes in subdrain extent, location, grade, or material depending on conditions encountered during grading. All subdrains shall be surveyed by a land surveyor/civil engineer for line and grade after installation and prior to burial. Sufficient time should be allowed by the Contractor for these surveys. 6.0 Excavation Excavations, as well as over-excavation for remedial purposes, shall be evaluated by the Geotechnical Consultant during grading. Remedial removal depths shown on geotechnical plans are estimates only. The actual extent of removal shall be determined by the Geotechnical Consultant based on the field evaluation of exposed conditions during grading. Where fill-over-cut slopes are to be graded, the cut portion of the slope shall be made, evaluated, and accepted by the Geotechnical Consultant prior to placement of materials-for construction of the fill portion of the slope, unless otherwise recommended by the Geotechnical Consultant. 3030.1094 Leighton and Associates, Inc. GENERAL EARTHWORK AND GRADING SPECIFICATIONS Page 6 of 6 7.0 Trench Backfihls 7.1 The Contractor shall follow all OHSA and Cal/OSHA requirements for safety of trench excavations. 7.2 All bedding and backfill of utility trenches shall be done in accordance with the applicable provisions of Standard Specifications of Public Works Construction. Bedding material shall have a Sand Equivalent greater than 30 (SE>30). The bedding shall be placed to I foot over the top of the conduit and densified by jetting. Backfill shall be placed and densified to a minimum of 90 percent of maximum from 1 foot above the top of the conduit to the surface. 7.3 The jetting of the bedding around the conduits shall be' observed by. -the Geotechnical Consultant. 7.4 The Geotechnical Consultant shall test the trench backfill for relative compaction. At least one test should be made for every 300 feet of trench and,2 'feet of fill. 7.5 Lift thickness of trench backfill shall not exceed those allowed in the Standard Specifications of Public Works Construction unless the Contractor can demonstrate to the Geotechnical Consultant that the fill lift can be compacted to the minimum relative compaction by his alternative equipment and method. 3030.1094 FILL SLOPE PROJECTED PLANE- 1 TO 1 MAXIMUM FR TOE OF SLOPE TO APPROVED GROUND EXISTING GROUND SURFACE 2' MIN.
