PURPOSE AND SCOPE This report presents the results of a geotechnical investigation for the proposed Poinsettia Properties Sewer Pump Station located in Carlsbad, California (see Vicinity Map, Figure 1). The purpose of the investigation was to evaluate the surface and subsurface soil and geologic conditions at the site, and based on the conditions encountered, provide recommendations pertaining to the geotechnical aspects of developing the pump station site as presently proposed. Specific geotechnical parameters required for design were provided to us via facsimile prepared by Nolle & Associates dated October 5, 2001. The scope of the field investigation included a geologic site reconnaissance, advancing one exploratory boring, and sampling the subsurface soils. Due to existing underground utilities, the exploratory boring was performed just east of the proposed pump station footprint. Additionally, a review of aerial photographs and relevant soil and geological literature concerning the site was performed. This included a review of the geotechnical investigation report for the Poinsettia Properties project entitled Update Geotechnical Investigation, Poinsettia Property, Carlsbad, California, prepared by Geocon Incorporated, dated July 20, 2000, and the plans entitled Grading and Erosion Control Plans for Poinsettia Properties, Planning Areas 2, 3 & 4, prepared by Project Design Consultants, progress print dated August 20, 2001. Laboratory tests were performed on selected soil samples obtained at various depths in the exploratory boring to evaluate pertinent physical properties. Details of the field investigation and laboratory tests are presented in Appendices A and B, respectively. The recommendations presented herein are based on an analysis of the data obtained from the exploratory boring, laboratory tests, information obtained from the above referenced investigation report dated July 20, 2000, and our experience with similar soil and geologic conditions. 2. SITE AND PROJECT DESCRIPTION The proposed pump station will be constructed on Lot 225 of the Poinsettia Properties project, a residential development of approximately 220 single-family homes, located north of Poinsettia Lane and west of Avenida Encinas in Carlsbad, California (see Vicinity Map, Figure 1). Specifically, Lot 225 is within the southwestern-most corner of the project, adjacent to Poinsettia Lane. The pump station will consist of a concrete/masonry building which houses the wet well, electrical/mechanical equipment, and associated sewer mains (see Figure 2, Site Plan). Project No. 06514-52-03 -1 - October 16, 2001 The lowest part of the structure (wet well) will be located at approximately 30 feet below existing grade. Limited grading is anticipated for the building pad however, some cut/fill may be required for the surrounding improvements. The locations and descriptions contained herein are based upon a site reconnaissance and the Site Plan referenced above. If project details vary significantly from those outlined, Geocon Incorporated should be notified for review and possible revision of the recommendations presented herein prior to final design submittal. 3. SOIL AND GEOLOGIC CONDITIONS Two surficial soil types and two formational units were encountered during our field investigation. The surficial units consist of topsoils and alluvial soils and is underlain by formational soils consisting of Terrace Deposits and the Santiago Formation as discussed below. The approximate lateral extent of the geologic units is presented on Figure 3, Geologic Map. 3.1 Topsoils (Unmapped) Topsoils consisting of loose, dry to moist, fine silty sand and sandy silt cover the area of Lot 225. The topsoils average 2 to 3 feet in thickness and generally exhibit low expansion characteristics. Removal and recompaction of topsoils will be required in areas to receive settlement sensitive structures. 3.2 Alluvium (Qal) Alluvial soils were found at the surface within the eastern portion of Lot 224 and extending to a depth within the exploratory boring of approximately 4 feet. These soils are characterized as loose to medium dense, moist to saturated, brown, clayey to silty sand and sandy clay to silt. Due to the unconsolidated condition, alluvial soils are potentially compressible when subjected to an increase in loading. All alluvial soils should be removed and replaced with compacted fill in areas of planned development. The proposed pump station however, is located within Lot 225, west of the contact between alluvium and the Terrace Deposits. The proposed pump station is not located in an area where alluvium is mapped. 3.3 Terrace Deposits (Qt) Underlying the alluvial soils in Lot 224 and below the topsoil within Lot 225 is dense Quaternary-age Terrace Deposits. The deposits encountered consist of fine- to medium-grained sand with some clay. The Terrace Deposits in their present condition are suitable for support of compacted fill soils and loads from the proposed development. Project No. 06514-52-03 -2- October 16,2001 3.4 Santiago Formation (Tsa) The Tertiary-age Santiago Formation is present below the Terrace Deposits at a depth on the order of 25 feet below the existing ground surface. The formation as encountered consists of dense to very dense, fine- to medium-grained sand with some clay and traces of silt. The Santiago Formation is suitable for support of compacted fill soils and loads from the proposed development. 4. GROUNDWATER Groundwater was encountered in the exploratory boring at a depth of approximately 13 feet below the existing ground surface. Groundwater will have a significant impact on the design and construction of the pump station. The contractor will likely have to implement an appropriate dewatering system. Furthermore, a buoyancy factor, hydraulic head pressure, and the use of an appropriate waterproof sealant/coating will be a consideration in the design of the structures anticipated to be below the water table. 5. GEOLOGIC HAZARDS 5.1 Faulting and Seismicity Based on our reconnaissance, and a review of published geologic maps and reports, the site is not located on any known active or potentially active fault trace. The nearest known active fault is the northern extension of the Rose Canyon Fault located approximately 4 miles to the west. Major earthquakes occurring on the Rose Canyon Fault, or other regional active faults located in the southern California area, could subject the site to moderate-to-severe ground shaking within the life span of the proposed structures. In order to determine the distance of known faults to the site, the computer program EQFAULT (Blake, 2000) was utilized. In addition to fault location, EQFAULT was used to estimate ground accelerations at the site for the maximum credible and maximum probable seismic events. Attenuation relationships presented by Sadigh et al. (1997) were used in the analysis to estimate site accelerations. The results of the deterministic analysis indicate that the Rose Canyon Fault zone, the Offshore Zone of Deformation, and Coronado Banks Fault Zone are among the dominant sources for potential ground motion occurring at the site. The "maximum credible earthquake" is defined as the maximum earthquake that appears capable of occurring under the presently known tectonic framework (California Division of Mines and Geology Notes, Number 43). The estimated maximum credible ground acceleration was determined to be approximately 0.48g for the Rose Canyon Fault. Presented on the following table are the earthquake events and site accelerations for faults considered most likely to subject the site to ground shaking. Project No. 06514-52-03 - 3 - October 16,2001 It is our opinion that the site could be subjected to moderate to severe ground shaking in the event of a major earthquake along any of the faults mentioned in Table 5.1; however, the seismic risk at the site is not considered significantly greater than the surrounding area. TABLE 5.1 Fault Name Rose Canyon Newport Inglewood Coronado Bank Elsinore-Julian Elsinore-Temecula Distance From Site (miles) 3'/2 7Vi 19'/2 26 26 Maximum Credible Event 6.9 6.9 7.4 7.1 6.8 Maximum Credible Site Acceleration (g) 0.48 0.32 0.17 0.10 0.08 5.2 Liquefaction Dense, formational soils of the Terrace Deposits underlie the site to a depth of approximately 23 feet followed by the Santiago Formation. Liquefaction occurs in loose cohesionless soils located beneath the water table that are subjected to large accelerations during strong earthquakes. Due to the dense nature of the formational units, it is our opinion that the potential for liquefaction of the site subsoils is low to remote. m m m m m m Project No. 06514-52-03 -4-October 16,2001 6. CONCLUSIONS AND RECOMMENDATIONS 6.1 General 6.1.1 It is our opinion that no soil or geologic conditions were encountered during the course of the investigation that would preclude the construction of the proposed structures provided the recommendations of this report are followed. 6.1.2 Subsurface conditions indicated by the exploratory boring may be extrapolated to reflect general soil/geologic conditions; however, some variations between locations should be anticipated. 6.1.3 Grading to achieve design finish grades for the pump station and associated improvements is anticipated to be relatively minor with cuts and fills on the order of one foot. The construction of cut or fill slopes are not planned for the project. 6.1.4 The proposed pump station and associated improvements will be founded in dense formational units. Conventional continuous and isolated spread footings are suitable for the proposed structures. 6.1.5 A relatively shallow groundwater condition exists at the site. Dewatering will be required during construction of the below-grade improvements. Other considerations may impact site development including sloping the sides of excavations as discussed below. 6.2 Excavation Characteristics and Dewatering 6.2.1 It is understood that the deepest floor slab of the below-grade portion of the structure (wet well) will be located on the order of 30 feet below the adjacent finish grade. Therefore, with the presence of shallow groundwater, dewatering and the stability of slopes excavated at or below the water level are important considerations during construction. 6.2.2 Based on our experience with the Terrace Deposits, we anticipate the soils to possess relatively moderate to high permeability. Therefore, it is our opinion that a well point system or a "cut off trench in which water may be pumped from may be suitable for dewatering construction excavations. The dewatering system, by any method, is considered the responsibility of the contractor including the design and implementation. Dewatering systems should be implemented by the contractor to provide safe and workable conditions within the temporary excavations. The contractor should consider any discharge permits and/or requirements of governing agencies. Project No. 06514-52-03 - 5 - October 16, 2001 6.2.3 It is our opinion that the soils on the site, in general, can be excavated with conventional heavy-duty grading equipment. Saturated soils excavated from below the groundwater level will require drying back to suitable moisture content prior to replacement as backfill or mixing with dry soils, if available. 6.2.4 Temporary excavations should be sloped back during construction of the underground facilities. These slopes should have an inclination no steeper than 1:1 (horizontal:vertical) in order to provide an adequate factor of safety and the groundwater should be lowered below the bottom of the excavation. It should be the contractor's responsibility to provide sufficient and safe support for the excavation, as well as nearby utilities, structures and other improvements that could be damaged by earth movements. The maximum inclination value assumes that no surcharge loading will encroach within a horizontal distance from the top of the excavation equal to the depth of excavation. If vertical temporary excavations are required, the contractor should provide appropriate sheet piling or shoring systems such as soldier piles with lagging. Temporary excavations should be in compliance with the applicable governing agency regulations. Design and implementation piling or of shoring systems are the responsibility of the contractor. The slopes should be monitored by a contractor representative familiar with applicable governing agency safety regulations. At any time, if soil sloughing or slope movement is noted, the excavation should be evacuated of personnel and the soils consultant contacted for further evaluation. 6.2.5 If an open excavation is restricted (such as by the existing utilities or property boundaries) other alternatives such as shoring/bracing or sheet-piling system may be utilized in lieu of the temporary excavations and dewatering. The contractor is considered responsible for design and implementation of any alternative system. However, the soils engineer should be consulted for supplemental soil design parameters. 6.3 Corrosion 6.3.1 Laboratory tests were performed on soil anticipated to be encountered to determine the percentage of water-soluble sulfate present. The test results indicate that concrete structures exposed to soils at the locations tested have a "negligible" water-soluble sulfate exposure as defined in the 1997 UBC Table 19-A-4. No special concrete design requirements are set forth in the UBC due to concrete exposed to "negligible" amount of sulfate. The results to the laboratory sulfate tests are presented in Appendix B, Table B-H 8.3.2 Geocon Incorporated does not practice in the field of corrosion engineering. Therefore, if improvements that could be susceptible to corrosion are planned, it is recommended that further evaluation by a corrosion engineer be performed. Project No. 06514-52-03 - 6 - October 16,2001 6.4 Grading 6.4.1 All anticipated grading for site development should be performed in accordance with the Recommended Grading Specifications contained in Appendix C, and in accordance with pertinent ordinances of the City of Carlsbad. Where recommendations of Appendix C conflict with this section of the report, the recommendations of this section shall take precedence. All earthwork, including fill and retaining and below grade wall and utility trench backfill, should be observed by, and all compacted fill tested by, representatives of Geocon Incorporated. 6.4.2 Site preparation should begin with the removal of all deleterious matter and vegetation in areas to be improved. The depth of removal should be such that the material to be used as fill is free of organic matter. Materials generated during stripping operations should be exported from the site to an approved location. In addition, the topsoil materials will require remedial grading to adjust moisture content and compact to specified relative compaction. 6.4.3 All backfilling operations should be performed to achieve subgrade elevations by compacting structural fill in layers. In general, native soils are suitable for reuse as fill if free from vegetation, debris and other deleterious matter. Layers of fill should be not thicker than will allow for adequate bonding and compaction. In areas of proposed improvements, all fill (including backfill and scarified ground surfaces) should be compacted to at least 90 percent of maximum dry density at or slightly above optimum moisture content in accordance with ASTM Test Procedure D1557-91. 6.4.4 Excavated soils that are saturated or overly wet of optimum will need to be dried back to a suitable moisture content. This may be accomplished by grading and aerating or mixing with drier materials, if available. Overly wet soils will be cause for rejection as suitable fill at the discretion of the soils engineer. 6.4.5 If existing underground utility lines are to be abandoned, they should be removed and the resulting excavation backfilled with properly compacted soil. 6.4.6 The design earth pressures provided herein for the below-grade pump station walls assume no additional loading resulting from compacting of backfill soils placed against the walls. We recommend that these soils be placed in shallow lifts and compacted with manually operated equipment. Consideration may be given to backfilling the zone adjacent to the walls with a clean granular material that would require less compaction effort. Project No. 06514-52-03 - 7 - October 16, 2001 6.5 Seismic Design Criteria The following table summarizes site-specific seismic design criteria obtained from the 1997 Uniform Building Code (UBC). The values listed in Table 6.5 are for the Rose Canyon Fault (located approximately 4 miles west of the site) that is identified as a Type B fault and is more dominant than the nearest Type A fault due to its close proximity to the site. TABLE 6.5 SEISMIC DESIGN PARAMETERS Parameter Seismic Zone Factor, Z Soil Profile Type Seismic Coefficient, C» Seismic Coefficient, Cv Near-Source Factor, Na Near-Source Factor, Nv Seismic Source Value 0.40 SD 0.44 0.74 1.0 1.2 B UBC Reference Table 16-1 Table 16-J Table 16-Q Table 16-R Table 16-S Table 16-T Table 16-U 6.6 Foundations-Generator and Transformer Buildings 6.6.1 The generator and transformer buildings can be supported on continuous strip footings and slab-on-grade founded on formational soils as previously discussed. 6.6.2 It is recommended that continuous strip footings have a minimum width of 12 inches and have a minimum depth of 12 inches as measured from the lowest adjacent finish grade. At that depth and width, strip footings may be designed with an allowable soil bearing pressure of 2,000 psf. This soil bearing pressure is for dead plus live loads and may be increased by one-third when considering transient loads due to wind or seismic forces. 6.6.3 Steel reinforcement for the footings should be designed by the project structural engineer, however, it is recommended that minimum reinforcement for continuous strip footings consist of four No. 4 reinforcing bars, two placed within the top of the footing and two placed near the bottom of the footing. 6.6.4 Concrete slabs for the structure should have a minimum thickness of 4 inches and be underlain by at least 4 inches of clean sand. Reinforcement, as a minimum, should consist of No. 3 reinforcing bars placed at 18 inches in both directions. Slab thickness and reinforcing Project No. 06514-52-03 -8-October 16,2001 should be reviewed by the structural engineer and design modifications specified if heavy or concentrated floor loading is anticipated. 6.6.5 All slabs expected to receive moisture sensitive floor covering or where moisture migration through the slab is undesirable should be underlain by a vapor barrier covered with 2 inches of the clean bedding sand recommended above. 6.6.6 All footing excavations should be observed by a representative of Geocon Incorporated prior to placing steel reinforcement or concrete. If unanticipated soils are encountered in the excavations, foundation modifications may be required. 6.7 Foundation-Pump Structure 6.7.1 It is our opinion that the main pump station structure can be supported on a reinforced concrete mat foundation founded on formational material and/or properly compacted fill. 6.7.2 An allowable soil bearing pressure of 3,000 psf may used in design of the mat foundation. A modulus of subgrade reaction, k, equal to 150 pci may also be assumed. Hydrostatic pressure exerted upward should be accounted for in design of the mat. An upward pressure of 1,650 psf may be used in design. 6.7.3 The concrete mat should be underlain by 6 inches of crushed rock. The thickness and reinforcing of the concrete mat should be designed by the structural engineer considering vertical loading as well as the hydrostatic (buoyant) pressures due to the presence of the shallow groundwater at an elevation above the floor level. 6.7.4 The excavation for the pump station structure should be observed by a representative of Geocon Incorporated prior to placing the gravel bedding, steel, or concrete. If anticipated soils are encountered in the excavation, foundation modifications may be required. 6.8 Lateral Earth Pressures-Retaining Walls 6.8.1 Retaining walls (at grade) not restrained at the top and having a level backfill surface should be designed for an active soil pressure equivalent to the pressure exerted by a fluid density of 30 pounds per cubic foot (pcf). Where the backfill will be inclined at no steeper than 2:1, an active soil pressure of 40 pcf is recommended. These soil pressures assume no surcharge at that the backfill materials within an area bounded by the wall and a 1:1 plane extending upward from the base of the wall possess an Expansion Index of less than 50. Project No. 06514-52-03 -9- October 16,2001 6.8.2 Unrestrained walls are those that are allowed to rotate more than 0.001 H at the top of the wall. Where walls are restrained from movement at the top, an additional uniform pressure of 7H psf (where H equals the height of the retaining wall portion of the wall in feet) should be added to the above active soil pressure. 6.8.3 The above pressure assumes that the retaining walls will be provided with a drainage system adequate to prevent the buildup of hydrostatic forces and are waterproofed as required by the project civil engineer or architect. The use of drainage openings through the base of the wall (weep holes, etc.) is not recommended where seepage could be a nuisance or otherwise impact the property adjacent to the wall. A drainage system behind the wall is recommended consisting of perforated pipe and the gravel encased in geotextile fabric (Mirafi 140N or equivalent). 6.8.4 In general, retaining wall foundations having a minimum depth and width of one foot may be designed for an allowable soil bearing pressure of 2,000 psf, provided the soil within 3 feet below the base of the wall has an Expansion Index of less than 90. The proximity of the foundation to the top of a slope steeper that 3:1 could impact the allowable soil bearing pressure. Therefore, Geocon Incorporated should be consulted where such a condition is anticipated. 6.9 Lateral Earth Pressures-Main Structure 6.9.1 The below grade walls of the pump station structure should be designed to withstand earth and hydrostatic pressures. It is assumed that the walls will be laterally supported by floor beams, therefore, they have been analyzed as nonyielding walls. It is recommended that these walls be designed to withstand a lateral pressure exerted by an equivalent fluid weight of 80 pcf, plus an additional uniform pressure of 7H psf (where H equals the below grade height of the wall). 6.9.2 Design of the wall should also account for any loading due to the presence of adjacent structures, if present. In these areas, an additional uniform pressure should be applied in the design equal to 0.5q where q is the equivalent uniform surcharge loading of the adjacent structure in pounds per square foot (psf). Where a traffic surcharge occurs within a horizontal distance less than two-thirds the height of the wet well/pump room wall, an additional uniform horizontal pressure of 70 psf should be applied to the above lateral pressures. 6.9.3 Waterproofing and/or concrete design to mitigate migration of water through the walls should be specified by the design engineer. Project No. 06514-52-03 -10 - October 16,2001 6.10 Lateral Load Resistance 6.10.1 Lateral loads may be resisted by passive earth pressure and friction. Allowable passive earth pressures against shallow spread or continuous strip footings poured neat against properly compacted fill soils or to undisturbed formational soils should be considered as being equal to the forces exerted by a fluid unit weight of 300 pcf. A coefficient of friction of 0.40 may be used between the base of footings arid slabs and the soil for computing resistance to sliding. The friction coefficient may be combined with the allowable passive earth pressure when determining total resistance to lateral loads. 6.11 Site Drainage 6.11.1 Adequate drainage provisions are imperative. Under no circumstances should water be allowed to pond adjacent to footings. The site should be graded and maintained such that surface drainage is directed away from structures and the top of the slopes into swales or other controlled drainage devices. All roof and pavement drainage should be directed into splash block or into conduits which carry runoff away from the proposed structure. 6.12 Foundation and Grading Plan Review 6.12.1 Geocon Incorporated should review the grading plans, as well as any retaining wall plans, and foundation plans prior to final design submittal to determine if additional analysis/ recommendations are required. Project No. 06514-52-03 - 11 - October 16, 2001 LIMITATIONS AND UNIFORMITY OF CONDITIONS 1. The recommendations of this report pertain only to the site investigated and are based upon the assumption that the soil conditions do not deviate from those disclosed in the investigation.

The approximate location of the boring is shown on Figure 3, Geologic Map. The exploratory boring was advanced to a depth of 46 feet below existing grade utilizing a truck- mounted Ingersoll-Rand, A-300 drill rig equipped with an 8-inch-diameter hollow-stem auger. Relatively undisturbed samples were obtained from the borings by driving a three-inch O.D. tube sampler 12 inches into the undisturbed soil mass with a 140-pound hammer falling 30 inches. Standard Penetration Tests (SPT) were also performed at various depths in the borings. Bulk samples were also collected. The soils encountered in the excavation were visually examined and logged. The log of boring is presented in Figures A-l and A-2.

Rock fill may extend to the slope face, provided that the slope is not steeper than 2:1 (horizontal:vertical) and a soil layer no thicker than 12 inches is track-walked onto the face for landscaping purposes. This procedure may be utilized, provided it is acceptable to the governing agency, Owner and Consultant. 3.5. Representative samples of soil materials to be used for fill shall be tested in the laboratory by the Consultant to determine the maximum density, optimum moisture content, and, where appropriate, shear strength, expansion, and gradation characteristics of the soil. 3.6. During grading, soil or groundwater conditions other than those identified in the Geotechnical Report may be encountered by the Contractor. The Consultant shall be notified immediately to evaluate the significance of the unanticipated condition 4. CLEARING AND PREPARING AREAS TO BE FILLED 4.1. Areas to be excavated and filled shall be cleared and grubbed. Clearing shall consist of complete removal above the ground surface of trees, stumps, brush, vegetation, man-made structures and similar debris. Grubbing shall consist of removal of stumps, roots, buried logs and other unsuitable material and shall be performed in areas to be graded. Roots and other projections exceeding 1-1/2 inches in diameter shall be removed to a depth of 3 feet below the surface of the ground. Borrow areas shall be grubbed to the extent necessary to provide suitable fill materials. GI rev. 8/98 4.2. Any asphalt pavement material removed during clearing operations should be properly disposed at an approved off-site facility. Concrete fragments which are free of reinforcing steel may be placed in fills, provided they are placed in accordance with Section 6.2 or 6.3 of this document. 4.3. After clearing and grubbing of organic matter or other unsuitable material, loose or porous soils shall be removed to the depth recommended in the Geotechnical Report. The depth of removal and compaction shall be observed and approved by a representative of the Consultant. The exposed surface shall then be plowed or scarified to a minimum depth of 6 inches and until the surface is free from uneven features that would tend to prevent uniform compaction by the equipment to be used. 4.4. Where the slope ratio of the original ground is steeper than 6:1 (horizontahvertical), or where recommended by the Consultant, the original ground should be benched in accordance with the following illustration. TYPICAL BENCHING DETAIL Finish Grade Original Ground Finish Slope Surface Remove All Unsuitable Material As Recommended By Soil Engineer Slope To Be Such That Sloughing Or Sliding Does Not Occur See Note 1 See Note 2' DETAIL NOTES: No Scale (1) Key width "B" should be a minimum of 10 feet wide, or sufficiently wide to permit complete coverage with the compaction equipment used. The base of the key should be graded horizontal, or inclined slightly into the natural slope. (2) The outside of the bottom key should be below the topsoil or unsuitable surficial material and at least 2 feet into dense formational material. Where hard rock is exposed in the bottom of the key, the depth and configuration of the key may be modified as approved by the Consultant. m m GI rev. 8/98 4.5. After areas to receive fill have been cleared, plowed or scarified, the surface should be disced or bladed by the Contractor until it is uniform and free from large clods. The area should then be moisture conditioned to achieve the proper moisture content, and compacted as recommended in Section 6.0 of these specifications. 5. COMPACTION EQUIPMENT 5.1. Compaction of soil or soil-rock fill shall be accomplished by sheepsfoot or segmented-steel wheeled rollers, vibratory rollers, multiple-wheel pneumatic-tired rollers, or other types of acceptable compaction equipment. Equipment shall be of such a design that it will be capable of compacting the soil or soil-rock fill to the specified relative compaction at the specified moisture content. 5.2. Compaction of rock fills shall be performed in accordance with Section 6.3. 6. PLACING, SPREADING AND COMPACTION OF FILL MATERIAL 6.1. Soil fill, as defined in Paragraph 3.1.1, shall be placed by the Contractor in accordance with the following recommendations: 6.1.1. Soil fill shall be placed by the Contractor in layers that, when compacted, should generally not exceed 8 inches. Each layer shall be spread evenly and shall be thoroughly mixed during spreading to obtain uniformity of material and moisture in each layer. The entire fill shall be constructed as a unit in nearly level lifts. Rock materials greater than 12 inches in maximum dimension shall be placed in accordance with Section 6.2 or 6.3 of these specifications. 6.1.2. In general, the soil fill shall be compacted at a moisture content at or above the optimum moisture content as determined by ASTM D1557-91. 6.1.3. When the moisture content of soil fill is below that specified by the Consultant, water shall be added by the Contractor until the moisture content is in the range specified. 6.1.4. When the moisture content of the soil fill is above the range specified by the Consultant or too wet to achieve proper compaction, the soil fill shall be aerated by the Contractor by blading/mixing, or other satisfactory methods until the moisture content is within the range specified. GI rev. 8/98 6.1.5. After each layer has been placed, mixed, and spread evenly, it shall be thoroughly compacted by the Contractor to a relative compaction of at least 90 percent. m Relative compaction is defined as the ratio (expressed in percent) of the in-place •" dry density of the compacted fill to the maximum laboratory dry density as determined in accordance with ASTMD1557-91. Compaction shall be continuous m over the entire area, and compaction equipment shall make sufficient passes so that the specified minimum relative compaction has been achieved throughout the entire fill. ** m 6.1.6. Soils having an Expansion Index of greater than 50 may be used in fills if placed at M least 3 feet below finish pad grade and should be compacted at a moisture content generally 2 to 4 percent greater than the optimum moisture content for the material. „ 6.1.7. Properly compacted soil fill shall extend to the design surface of fill slopes. To * achieve proper compaction, it is recommended that fill slopes be over-built by at m least 3 feet and then cut to the design grade. This procedure is considered •• preferable to track-walking of slopes, as described in the following paragraph. m IP6.1.8. As an alternative to over-building of slopes, slope faces may be back-rolled with a heavy-duty loaded sheepsfoot or vibratory roller at maximum 4-foot fill height intervals. Upon completion, slopes should then be track-walked with a D-8 dozer P or similar equipment, such that a dozer track covers all slope surfaces at least •* twice. _ m6.2. Soil-rock fill, as defined in Paragraph 3.1.2, shall be placed by the Contractor in accordance with the following recommendations: in m 6.2.1. Rocks larger than 12 inches but less than 4 feet in maximum dimension may be * incorporated into the compacted soil fill, but shall be limited to the area measured *> 15 feet minimum horizontally from the slope face and 5 feet below finish grade or ^^T3 feet below the deepest utility, whichever is deeper. ^ 6.2.2. Rocks or rock fragments up to 4 feet in maximum dimension may either be ^individually placed or placed in windrows. Under certain conditions, rocks or rock fragments up to 10 feet in maximum dimension may be placed using similar m methods. The acceptability of placing rock materials greater than 4 feet in Ml maximum dimension shall be evaluated during grading as specific cases arise and shall be approved by the Consultant prior to placement. GI rev. 8/98 6.2.3. For individual placement, sufficient space shall be provided between rocks to allow for passage of compaction equipment. 6.2.4. For windrow placement, the rocks should be placed in trenches excavated in properly compacted soil fill. Trenches should be approximately 5 feet wide and 4 feet deep in maximum dimension. The voids around and beneath rocks should be filled with approved granular soil having a Sand Equivalent of 30 or greater and should be compacted by flooding. Windrows may also be placed utilizing an "open-face" method in lieu of the trench procedure, however, this method should first be approved by the Consultant. 6.2.5. Windrows should generally be parallel to each other and may be placed either parallel to or perpendicular to the face of the slope depending on the site geometry. The minimum horizontal spacing for windrows shall be 12 feet center-to-center with a 5-foot stagger or offset from lower courses to next overlying course. The minimum vertical spacing between windrow courses shall be 2 feet from the top of a lower windrow to the bottom of the next higher windrow. 6.2.6. All rock placement, fill placement and flooding of approved granular soil in the windrows must be continuously observed by the Consultant or his representative. 6.3. Rock fills, as defined in Section 3.1.3., shall be placed by the Contractor in accordance with the following recommendations: 6.3.1. The base of the rock fill shall be placed on a sloping surface (minimum slope of 2 percent, maximum slope of 5 percent). The surface shall slope toward suitable subdrainage outlet facilities. The rock fills shall be provided with subdrains during construction so that a hydrostatic pressure buildup does not develop. The subdrains shall be permanently connected to controlled drainage facilities to control post-construction infiltration of water. 6.3.2. Rock fills shall be placed in lifts not exceeding 3 feet. Placement shall be by rock trucks traversing previously placed lifts and dumping at the edge of the currently placed lift. Spreading of the rock fill shall be by dozer to facilitate seating of the rock. The rock fill shall be watered heavily during placement. Watering shall consist of water trucks traversing in front of the current rock lift face and spraying water continuously during rock placement. Compaction equipment with compactive energy comparable to or greater than that of a 20-ton steel vibratory roller or other compaction equipment providing suitable energy to achieve the GI rev. 8/98 required compaction or deflection as recommended in Paragraph 6.3.3 shall be utilized. The number of passes to be made will be determined as described in Paragraph 6.3.3. Once a rock fill lift has been covered with soil fijl, no additional rock fill lifts will be permitted over the soil fill. 6.3.3. Plate bearing tests, in accordance with ASTM D1196-64, may be performed in both the compacted soil fill and in the rock fill to aid in determining the number of passes of the compaction equipment to be performed. If performed, a minimum of three plate bearing tests shall be performed in the properly compacted soil fill (minimum relative compaction of 90 percent). Plate bearing tests shall then be performed on areas of rock fill having two passes, four passes and six passes of the compaction equipment, respectively. The number of passes required for the rock fill shall be determined by comparing the results of the plate bearing tests for the soil fill and the rock fill and by evaluating the deflection variation with number of passes. The required number of passes of the compaction equipment will be performed as necessary until the plate bearing deflections are equal to or less than that determined for the properly compacted soil fill. In no case will the required number of passes be less than two. 6.3.4. A representative of the Consultant shall be present during rock fill operations to verify that the minimum number of "passes" have been obtained, that water is being properly applied and that specified procedures are being followed. The actual number of plate bearing tests will be determined by the Consultant during grading. In general, at least one test should be performed for each approximately 5,000 to 10,000 cubic yards of rocJtfill placed. 6.3.5. Test pits shall be excavated by the Contractor so that the Consultant can state that, in his opinion, sufficient water is present and that voids between large rocks are properly filled with smaller rock material. In-place density testing will not be required in the rock fills. 6.3.6. To reduce the potential for "piping" of fines into the rock fill from overlying soil fill material, a 2-foot layer of graded filter material shall be placed above the uppermost lift of rock fill. The need to place graded filter material below the rock should be determined by the Consultant prior to commencing grading. The gradation of the graded filter material will be determined at the time the rock fill is being excavated. Materials typical of the rock fill should be submitted to the Consultant in a timely manner, to allow design of the graded filter prior to the commencement of rock fill placement. GI rev. 8/98 6.3.7. All rock fill placement shall be continuously observed during placement by representatives of the Consultant. 7. OBSERVATION AND TESTING 7.1. The Consultant shall be the Owners representative to observe and perform tests during clearing, grubbing, filling and compaction operations. In general, no more than 2 feet in vertical elevation of soil or soil-rock fill shall be placed without at least one field density test being performed within that interval. In addition, a minimum of one field density test shall be performed for every 2,000 cubic yards of soil or soil-rock fill placed and compacted. 7.2. The Consultant shall perform random field density tests of the compacted soil or soil-rock fill to provide a basis for expressing an opinion as to whether the fill material is compacted as specified. Density tests shall be performed in the compacted materials below any disturbed surface. When these tests indicate that the density of any layer of fill or portion thereof is below that specified, the particular layer or areas represented by the test shall be reworked until the specified density has been achieved. 7.3. During placement of rock fill, the Consultant shall verify that the minimum number of passes have been obtained per the criteria discussed in Section 6.3.3. The Consultant shall request the excavation of observation pits and may perform plate bearing tests on the placed rock fills. The observation pits will be excavated to provide a basis for expressing an opinion as to whether the rock fill is properly seated and sufficient moisture has been applied to the material. If performed, plate bearing tests will be performed randomly on the surface of the most-recently placed lift. Plate bearing tests will be performed to provide a basis for expressing an opinion as to whether the rock fill is adequately seated. The maximum deflection in the rock fill determined in Section 6.3.3 shall be less than the maximum deflection of the properly compacted soil fill. When any of the above criteria indicate that a layer of rock fill or any portion thereof is below that specified, the affected layer or area shall be reworked until the rock fill has been adequately seated and sufficient moisture applied. 7.4. A settlement monitoring program designed by the Consultant may be conducted in areas of rock fill placement. The specific design of the monitoring program shall be as recommended in the Conclusions and Recommendations section of the project Geotechnical Report or in the final report of testing and observation services performed during grading. GI rev. 8/98 7.5. The Consultant shall observe the placement of subdrains, to verify that the drainage devices have been placed and constructed in substantial conformance with project specifications. 7.6. Testing procedures shall conform to the following Standards as appropriate: 7.6.1. Soil and Soil-Rock Fills: 7.6.1.1. Field Density Test, ASTM D1556-82, Density of Soil In-Place By the Sand-Cone Method. 7.6.1.2.

PROTECTION OF WORK 8.1. During construction, the Contractor shall properly grade all excavated surfaces to provide positive drainage and prevent ponding of water. Drainage of surface water shall be controlled to avoid damage to adjoining properties or to finished work on the site. The Contractor shall take remedial measures to prevent erosion of freshly graded areas until such time as permanent drainage and erosion control features have been installed. Areas subjected to erosion or sedimentation shall be properly prepared in accordance with the Specifications prior to placing additional fill or structures. 8.2. After completion of grading as observed and tested by the Consultant, no further excavation or filling shall be conducted except in conjunction with the services of the Consultant. GI rev. 8/98 9. CERTIFICATIONS AND FINAL REPORTS 9.1. Upon completion of the work, Contractor shall furnish Owner a certification by the Civil Engineer stating that the lots and/or building pads are graded to within 0.1 foot vertically of elevations shown on the grading plan and that all tops and toes of slopes are within 0.5 foot horizontally of the positions shown on the grading plans. After installation of a section of subdrain, the project Civil Engineer should survey its location and prepare an as-built plan of the subdrain location^ The project Civil Engineer should verify the proper outlet for the subdrains and the Contractor should ensure that the drain system is free of obstructions. 9.2. The Owner is responsible for furnishing a final as-graded soil and geologic report satisfactory to the appropriate governing or accepting agencies. The as-graded report should be prepared and signed by a California licensed Civil Engineer experienced in geotechnical engineering and by a California Certified Engineering Geologist, indicating that the geotechnical aspects of the grading were performed in substantial conformance with the Specifications or approved changes to the Specifications.
