Dear Ms. Nasatir: The purpose of this letter is to formally acknowledge and document the changes provided in your e-mail of December 1 lth and December 12Ih, 2001 and Kleinfelder’s e-mail of December 121h, 2001 (copies of these e-mails are attached for reference). The following is a summary of the key points: ,- Kleinfelder acknowledges the change in burial depths for the GMF (raised from 12 feet deep to 4 feet) and for the CCB and Thickener (raised from 12 feet deep to 3 feet and 7 feet, respectively). Based on our September 12, 2001 report, these structures can be designed for 3000 psfbearing as you have indicated in your December 12‘h e-mail. If the GMF/MF/RO pad will be supported entirely in cut on natural formation (that is, not supported on existing fills or partially supported on cut and fill), then placing the pad on 2 feet of newly compacted fill isn’t required. The 2 feet of fill is only required where the slab will not be entmly bearing on native, undisturbed terrace deposirs. Since the GMF/MF/RO pad will already be 12 inches thick (and, therefore, fairly rigid) has no objection if a 4-inch thick gravel layer is not placed between the prepared and the need to mitigate moisture movement does not appear to be important, Kleinfelder subgrade and the bottom of the concrete pad. 51-594701/51 IIL5OE.doc Page I of 2 Copynght ?M)I Kleinfelder, Inc. h~ E I N F E I. !2 E R .5i)lS Shoreham Place. ?;an DieSo.

Page iv of iv KLEINFELDER 7 1.0 WTRODUCTION This report presents the results of our geotechnical investigation for the proposed Carlsbad Water Recycling Facility to be located in Carlsbad directly east of Avenida Encinas between Palomar Airport Road and Macadamia Drive. This investigation consisted of a review of our previous work at the Encina Water Pollution Control Facility located directly north of the current study site, a subsurface investigation, laboratory testing, and engineering analysis. The site is located as shown on the Vicinity Map, Figure 1. A site plan showing approximate boring locations, which is based on civil drawings prepared by Black & Veatch, is presented as Figure 2, Boring Location Plan. 1.1 PROJECT DESCFUPTION The phase of site development covered by this report addresses the following improvements to be constructed: an administration building; an electrical room; two granular media filter (GMF) units; a granular media filtratiodmicrofiltratiodreverse osmosis (GMF/MF/RO) pad; a reverse osmosis (RO) structure; a microfiltration (MF) structure; a chemical storage area; a thickener chemical storage area; a waste thickener; and a chlorine contact basin. - Sidewalks, pavements, pipelines, lighting, and landscaping will also be added to complete the project. The administration building will be an 11,500 square foot, lightly loaded, single story building with bearing walls. The electrical room will be a small, single story building (650 square feet). The GMF units will be concrete basins that will be partially buried (maximum anticipated burial .- 51-594701/51 I IR605.doc Copyight 2001 Klcinfeldn. Inc Page I of 24 September 12,2ODI KLEINFELDER ,?" depth of 10 to 12 feet); these two initial units will cover a footprint area of approximately 756 square feet. The GMFMF/RO pad will be a slab-on-grade structure to support the h4F structure (a shipping container with a canopy) and will surround the GMF and RO structures. The RO structure will contain a 4 feet wide, 5 feet deep concrete trench and a canopy. The chemical storage area will be a slab-on-grade concrete pad with containment curbs that will be placed in a shallow excavation. It will have a 20-foot high canopy cover. The thickener chemical storage area will also be a slab-on-grade concrete containment pad placed in a shallow excavation. The chlorine contact basin will be a partially buried tank (estimated maximum burial depth of 10 to 12 feet) covering a footprint area of about 160 feet in length by 40 feet in width. The waste thickener will also be a partially submerged basin (burial depth approximately 12 feet) with a footprint area of about 20 feet by 30 feet. Except for the basin excavations, the anticipated site grading is expected to be minimal. Cuts and fills for general site grading are expected to be on the order of 1 to 5 feet to maintain the general flatness of the existing site with minor sloping for surface cross-drainage. 1.2 PURPOSE AND SCOPE OF SERVICES ~- The purpose of our investigation was to evaluate the surface and subsdace soil and geologic conditions at the site in order to provide geotechnical information and recommendations to facilitate design of this phase of project development. The scope of our services for this report consisted of Review of our previous preliminary report for the Encina Water Pollution Control Facility (Kleinfeldn Project No. 51-507601, dated February 18, 1999); Investigation of the subsurface conditions by drilling three borings; (see Appendix A); Laboratory testing of representative samples of soil and geologic materials; Engineering analysis of field and research data; and 0 Preparation of this report presenting our findings, conclusions, and recommendations. Our scope of services was outlined in our contract with Black & Veatch dated August 3,2001. .- SI-594701RIIIR6OS.doc Copyright 2001 Klcinfcldcr, Inc. Page 2 of 24 septrmbcr 12.2001 ' KLEINFELDER .." The recommendations contained within this report are subject to the limitations presented in Section 7.0. An information sheet prepared by ASFE (the Association of Engineering Firms Practicing in the Geosciences) is also included as Appendix E. We recommend that all individuals utilizing this report read the limitations along with the attached document. 1.3 AUTHORIZATION Our work for this study was authorized by our contract with Black & Veatch dated August 3,2001 .- 51-594701/51 I IR605.d~ Copyight 2001 Klcinfclder, Inc. Page 3 of 24 September 12,2001 KLEINFELDER - 2.0 INVESTIGATIVE METHODS 2.1 GEOLOGIC EVALUATION Our geologic evaluation consisted of reviewing our previous report prepared for the Encina Water Pollution Control Facility equalization basins, reviewing published geologic maps, reviewing our seismic hazard evaluation for the Encina plant (dated March 3, 1999). observation of site conditions at the time of our subsurface investigation, our three borings, and our laboratory tests. 2.2 SUBSURFACE INVESTIGATION The subsurface exploration for this study was completed on August 6, 2001. Three borings were drilled to depths ranging from 21.5 feet to 25 feet below the existing ground surface. The approximate locations of the borings are shown on Figure 2. More detailed subsurface conditions are presented on the boring logs in Appendix A. The three borings were drilled using an Ingersoll-Rand A300 drill rig equipped with 8-inch diameter hollow stem augers. All of the borings were drilled to their full depth without noticeable ,- resistance. The excavation and sampling procedures were in general accordance with ASTM Method D 420 "Standard Guide to Site Characterization for Engineering Design and Construction Purposes." Our field engineer maintained a log of the test borings, visually classified soils according to the Unified Soil Classification System, and obtained representative samples of the subsurface materials. Bulk soil samples were obtained from the cuttings created by the drilling operations. Disturbed driven samples were also obtained using a 3.0-inch diameter California (CAL) sampler with rings that had an inside diameter of 2.5 inches. The CAL sampler was driven using a 140-pound hammer with a 30-inch drop. The sampler was driven for a maximum distance of 18 inches. The number of blows required to drive the sample over each 6-inch increment was recorded. Soil samples obtained from the borings were packaged and sealed in the field to reduce moisture loss and disturbance, and returned to our San Diego laboratory for further testing. All of the soil borings were backfilled with soil cuttings from the test borings. 51-594701151 I IR605.doc Copyright 2001 Kleinfelder. Inc. Page 4 of 24 September 12,2001 KLEINFELDER .-" 2.3 LABORATORY TESTING Laboratory tests were performed on selected samples at various depths in the borings to evaluate pertinent physical and chemical properties. Details of the laboratory testing program are presented in Appendix B. fil-594701/5lllR605.doc Copyight 2001 Kleinfelda, inc. Page 5 of 24 September 12.2001 ’ KLEINFELDER .e 3.0 SITE AND SUBSURFACE CONDITIONS 3.1 SITE CONDITIONS The site is relatively flat with the exception of small drainage at the east side of the north end of the property that drains from south to north. The site is presently undeveloped and is covered with sparse native vegetation and bare earth. 3.2 GEOLOGIC SETTING The project area is underlain by a thin veneer of topsoillartificial fill (maximum thickness of 24 inches) over Pleistocene terrace deposits. These marine deposits consist of moderately hard to hard clays and fine-to medium-grained, weakly to moderately cemented, clayey and silty sands and sandstones. The terrace deposits extended to the bottoms of our borings. 3.3 SUBSURFACE CONDITIONS Boring 1 was completed in the administration building area. At this location we encountered 6 inches of topsoil over 18 inches of medium dense clayey sand artificial fill. From a depth of 2 feet to 6 feet we encountered medium dense to dense clayey sand native terrace deposits. From 6 feet to about 14 feet, we encountered very stiff to hard sandy clay. Dense silty sand and sand with some silt was found beneath the clay layer to the maximum depth of our test boring, 21.5 feet. No groundwater or caving conditions were encountered. .- Boring 2 was located in the vicinity of the GMF units. The subsurface conditions were similar to Boring 1 with the exceptions that the artificial fill only extended to a depth of about 1 foot and the sandy clay only extended from about 6 feet to 9 feet before the silty sand was found again. Boring 3 was located in the chlorine contact basin and exhibited subsurface conditions similar to Boring 1 except that the topsoiVfil1 layer was only about 6 inches thick. The sandy clay layer started at a depth of 2 feet and extended to a depth of 12 feet before the dense silty sand was encountered. Although no groundwater or obvious seepage conditions were encountered in OUT test borings, groundwater conditions may vary with time due to irrigation practices, seasonal rainfall, construction activities, or other factors that were not apparent at the time of our field exploration. 51-594701/SlllR605.doc Copyright 2001 Kleinfelder, Inc. Page 6 of 24 KLEINFELDER - 3.4 REGIONAL FAULTING, SEISMICITY, AND LIQUEFACTION POTENTIAL The project site is not located within an Alquist-Priolo Earthquake Fault Zone. However, the site and its vicinity are located in an area traditionally characterized by lower seismic activity. Based on our previous borings for the Encina plant, the boring data from this study, the presence of dense formational temace deposits within 2 feet of the ground surface, the potential for liquefaction is low and is not considered a potential hazard at this site. Specific discussion of faulting and seismicity, along with ground motion criteria in terms of peak ground accelerations and design response spectra, are provided in Appendix C. Uniform Building Code (UBC) seismic design parameters are provided in Section 5.5.2. 51-594701/5111R605.doc Copyright 2001 Kleinfelder, Inc. September 12. 2001 KLEINFELDER ,- 4.0 CONCLUSIONS Based upon information collected during our investigation and our review of geologic references, it is our opinion that the proposed project can be constructed using conventional wall and spread foundations and techniques for excavations, provided the recommendations contained in this report are followed. The following conclusions were developed kom our investigation: The site is not located within a State of California Alquist-Priolo Earthquake Fault Zone or located where liquefaction is considered a potential hazard. Although there are no known active faults crossing the site which would affect the proposed construction, the site is located in the seismically-active Southern California area. The structures should be designed to tolerate seismic shaking. The relatively thin topsoillfill veneer at the top of the site should be completely removed or recompacted in areas to be developed. The native soils are stable and dense. We anticipate they can support conventional wall and spread footings with tolerable settlements. .-. With the exception of the sandy clay soils found at depths of 2 to 6 feet below the existing ground surface, the on-site materials are generally suitable for use as engineered fill. The sandy clay soils should not be used as backfill, but can be used as general site grading fill if placed at least 4 feet below finish pad surface. It is unlikely that dewatering will be required to the maximum depths of excavation of 10 to 12 feet proposed for excavation of the basins and utilities. 51-.594701/51 llR60S.doc Copynght 2001 Klcinfcldcr, Inc. Page 8 of 24 Seplembn 12.200l I(F1 KLEINFELDER r 5.0 DISCUSSION AND RECOMMENDATIONS 5.1 SITE GRADING 5.1.1 General All site preparation and earthwork operations should be performed in accordance with applicable codes. All reference to maximum dry density is established in accordance with American Society for Testing and Materials (ASTM) ASTM D 1557. We recommend that site earthwork and construction be performed in accordance with the following recommendations and the guidelines presented in the Guidelines for Earthwork Construction included in Appendix D. In case of conflict, the following recommendations supersede those outlined in Appendix D. 5.1.2 Pre-construction Conference We recommend that a pre-construction conference be held. Owner representatives, the civil engineer, geotechnical consultant, and contractor should be in attendance to discuss the plans and the project. 5.1.3 Construction Observation I- The recommendations presented in this report are based on our understanding of the proposed project and on our evaluation of the data collected. The interpolated subsurface conditions should be evaluated in the field during construction. Final project drawings and specifications should be reviewed by the project geotechnical consultant prior to the commencement of construction. The project geotechnical consultant should observe the grading and backfXng operatlons. Compacted fill and backfill soils should be tested for specified compaction by the geotechnical consultant. .-. 5.1.4 Site Preparation If encountered, man-made materials including structural foundations, floor slabs, buried pipes, utilities, etc. should be completely removed. All surficial vegetation and deleterious material should be stripped and completely removed from the site. Excavations for removal of any man-made items should be dish-shaped and backfilled with properly compacted engineered fill. Locations of sanitary sewers, storm drains, water mains, and other utilities should be verified in the field at the time of construction. If field verified to be within the footprint of a proposed improvement, then the existing utilities should be relocated so that they are not within the 51-594701/5111R605.doe Copyright 2001 Kleinfelda, Inc. Page 9 of 24 September 12.ZOol KLEINFELDER _I footprint of the improvement. Abandoned utilities should be completely removed, and the loose backfill removed and replaced. The trench created by relocating the existing utilities should be backfilled in accordance with Section 5.2.2 of this report. 5.1.5 Recommendations for Treatment of Undocumented Fill Materials We recommend that existing undocumented fill in structure areas (structure footprint and 5 feet horizontally outside of the structure footprint), flatwork, and driveway/parking areas be removed to native formation, which is expected to be 2 feet or less below the existing grade. Unless directed otherwise by the geotechnical consultant, the exposed surface of the remedial removals should be scarified, moisture conditioned, and recompacted as recommended in the sections below. Suitable removed materials, or imported materials, should then be utilized as compacted structural fill. The areal extent and depths to which the fill should be removed should be evaluated by the geotechnical consultant's representative in the field based on the materials exposed. Any unsuitable materials such as organic matter or oversized material should be selectively removed and disposed off site. We recommend that the foundation components of the proposed structures be founded either entirely in formational or entirely in compacted fill materials; foundations of any given structure should not transition between native and fill support. 5.1.6 Excavation Characteristics The results of our field exploration program indicate the project site, as presently proposed, is underlain by a thin veneer of undocumented fill over terrace deposits. The on-site materials should generally be excavatable by heavy-duty earthmoving equipment in good working condition. 5.1.7 Engineered Fill Fill materials generated fiom the on-site soils are generally suitable for placement as compacted fill provided they are ftee of oversized rock, clay clods, organic materials, and deleterious debris. Rocks greater than 3 inches in diameter should not be placed within 2 feet of finished grade. Oversize material in excess of 6 inches in diameter should not be used in structural fill. Fill soil placed within the upper 4 feet of finished grade in structural areas should consist of granular material with a very low to low expansion index (expansion index of 50 or less) as evaluated by" UBC Standard 18-2 (Expansion Index Test). More expansive soil may be placed in the non-structural areas on the site or at depths of 4 feet or more. Selective grading may be required to achieve a 4-foot zone of very low to low expansive soils. Fill should be moisture conditioned .-~" . . ... . . ~ . . . --- - "" .- " -. ,- 51-594701/5111R605.doc Copyight 2001 Kleinfelder. Inc. Page 10of24 September I2.2001 . KLEINFELDER -. to near optimum and be compacted to 90 percent or more relative compaction in accordance with ASTM D 1557. Expansive soils should be similarly compacted, but at a moisture content of 2 to 3 percent above optimum. Although the optimum lift thickness for fill soils will be dependent on the type of compaction equipment utilized, fill should generally be placed in uniform lifts not exceeding approximately 8 inches in loose thickness. Some oversized material, rocks, or hard lumps greater than 6 inches in dimension should be anticipated from excavations and should not be used in compacted fills. In pavement areas the upper 12 inches of subgrade soils should be moisture conditioned to a moisture content near optimum content and compacted to 95 percent or more of the maximum laboratory dry density, as evaluated by ASTM D 1557. 5.1.8 Import Materials We recommend that import material, if any, consist of granular, very low to low expansive material (expansion index of 50 or less) as evaluated by UBC Standard 18-2 (Expansion Index Test) with low corrosivity characteristics. Low corrosivity material is defined as having a minimum resistivity of more than 2,000 ohm-cm when tested in accordance with California Test 643, unless defined otherwise by the corrosion consultant. Import material should be evaluated - by the geotechnical consultant at the borrow site for its suitability as fill prior to importation to the project site. 5.1.9 Temporary Slopes Except as discussed with regard to utility trench excavation, temporary cut slopes in existing fill soils should not be steeper than 1.5:l. Cut slopes in underlying formational materials to overall excavation depths of 20 feet can be as steep as 1:l. If steeper side slopes should be necessary due to construction restrictions or excavations are deeper than 20 feet, shoring and bracing should be installed. OSHA and Cal-OSHA requirements should be observed for all excavations. If excavations deeper than 25 feet below existing site grades will be made, we should be contacted so that we can prepare recommendations for appropriate side slopes on a case-by-case basis. The contractor should retain a competent geotechnical engineer to develop systems to mitigate the effects of settlement induced by excavations. On a case-by-case basis, the contractor should protect structures which fall on a wedge formed by a 2 horizontal to 1 vertical slope extending from the bottom of excavation, and on settlement-sensitive structures falling on a wedge 4 - horizontal to 1 vertical slope extending from the bottom of the excavation. The protection 51-594701151 I IRM)S.doc Copyright 2001 Klcinfcldcr, inc Page I I of24 September 12,ZOOl KLEINFELDER ,.” systems proposed by the contractor should be reviewed by the client’s geotechnical engineer prior to constructing these protective systems. 5.1.10 Permanent Slopes In general, both cut and fill slopes up to a maximum height of 25 feet can be as steep as 2:l. If fill slopes higher than 25 feet will be constructed, we should review each situation on a case-by- case-by-case basis. Flatter side slopes or benching may be needed for fill slopes higher than 25 feet. New fill slopes should not be constructed above existing fill soils. Where new fill slopes will be built, the existing fill should be excavated and a keyway constructed into the underlying formational materials. The dimensions and depth of the keyway will depend on final slope configurations and heights. For fill slopes constructed at 2:l up to 25 feet high, a keyway having a minimum width of 10 feet and a minimum depth of 3 feet into formational material would be appropriate. New fill placed on existing slopes that are steeper than 5:l should be keyed and benched into the existing hillside. Keyway recommendations are presented in the preceding paragraph. Benches should be a minimum of 10 feet in width and spaced at no more than 4-fOOt vertical height intervals. Subsurface drainage may be needed depending on slope configurations and facility locations. We should review project plans prior to final design and prepare recommendations for subsurface drains, if needed. If any zones of specific seepage, are encountered during construction, they should be addressed as recommended by the geotechnical engineer in the field at that time. 5.2 UTILITY TRENCH EXCAVATIONS 5.2.1 Temporary Trench Excavations Shallow, temporary utility trench excavations are anticipated for installation of the required utility lines. All vertical or steeply sided trench excavations greater than 5 feet in depth should be braced and shored in accordance with good construction practice and all applicable safety ordinances and codes. - The on-site terrace deposits are generally classified as Tpe B soils for evaluating OSHA sloping or shoring requirements. Heavy construction loads, such as those resulting from stockpiles and heavy machinery, should be kept a sufficient distance away from the top of the excavation or 51-594701/511 IR60S.doc Copyright 2001 Kleinfclder, Inc. . KLflNFELDER - shoring to prevent unanticipated surcharge loading. All surface water should be diverted away kom excavations. If very steep or vertical-sided excavations in excess of 5 feet deep are necessary, we recommend the sidewalls be shored in accordance with OSHA standards to provide temporary trench stability during construction. The contractor should be responsible for the structural design and safety of the temporary shoring system and we recommend that this design be submitted to Kleinfelder for review and approval. 5.2.2 Pipe Bedding and Trench Backfill Pipe bedding should consist of sand or similar granular material having a sand equivalent value of 30 or less. The sand should be placed in a zone that extends a minimum of 4 inches below and 12 inches above the pipe for the full trench width. The bedding material should be compacted to a minimum of 90 percent of the maximum dry density. Trench backfill above pipe bedding may consist of approved, on-site or import soils placed in lifts no greater than 8 inches loose thickness and compacted to 90 percent of the maximum dry density. 5.3 FOUNDATION AND SLABS FOR STRUCTURES 5.3.1 Administration Building, Shallow Structures, and Concrete Slab-on-Grade The administration building and shallow structures are those structures expected to have ground floor levels near existing site grades. For purposes of this report, shallow structures are considered to be those having lowest levels within 5 feet of existing site grades. The administration building and shallow structures can be supported on spread footing foundations placed in engineered fill or undisturbed terrace deposits underlying the existing undocumented fill. Existing fill soils are not suitable for support of foundations and slabs. Foundations for each individual structure should be supported in the same type of material. Where foundations will be founded in fill, all of the foundations for the structure should be underlain by at least 2 feet of newly compacted fill. In some cases, excavation into the terrace deposits may be necessary to provide this thickness. It may be more economical for all the foundations in a particular structure to be bottomed in terrace deposits where the top of the formation material exists at relatively shallow depths below foundation grades. Where slab-on- ~- grade floors would be located above a transition between fill and formational material, at least 2 feet of engineered fill should be provided beneath the slab. 51-594701/5111R605.doe Copyright 2001 Kleinfeldn, Inc. Page I3 of 24 September IZ,ZOOI KLEINFELDER .- Foundations for shallow structures should be a minimum of 12 inches wide and be bottomed at least 18 inches below the lowest adjacent outside final grade. Foundations supported in newly compacted fill can be designed for an allowable bearing pressure of 2,000 pounds per square foot (psf) for dead plus long-term live loads. Foundations bottomed in terrace deposits can be designed for an allowable bearing pressure of 3,000 psf. A one-third increase can be applied when considering a total of all loads, including wind or seismic forces. The outside bottom edges of footings should not be closer than five feet, measured horizontally, from the face of the nearest adjacent slope. Total settlements of footings and differential settlements between adjacent footings underlain by new compacted fill are expected to be on the order of % inch or less. Total settlements of footings and differential settlements between adjacent footings bottomed in terrace deposits should be less than 114 inch. Resistance to lateral loads will be provided by passive pressure on the faces of footings or other structural elements below grade and by friction along the bases of footings and slabs. For design purposes, a passive equivalent fluid pressure of 325 pounds per cubic @cf) can be used for both fill and formational material. A friction factor of 0.35 can be used for footings and slabs in recompacted fill or terrace deposits. Safety factors should be applied to both passive pressure and frictional resistance. The factor of safety should be selected by the structural engineer, but should not be less than 1.5 for static loads and 1.2 for transient loads such as earthquakes. 5.3.2 Concrete Slabs-On-Grade Slab-on-grade floors for the administration building and electrical room should be underlain by at least 4 inches of clean, free-draining gravel to provide uniform support for the slab and serve as a break to the rise of capillary moisture. Where moisture vapor penetration through the slab would be undesirable, such as where floor coverings would be placed, a moisture vapor barrier (plastic sheet at least 10 mils thick) can be placed between the slab and the rock. The plastic sheet should be overlain and underlain by 2 inches of moist, fine sand to provide a measure of protection during slab construction and promote the curing of concrete. For floors and walkways placed on granular engineered fill above a depth of 1.5 feet below the existing ground surface, a modulus of subgrade reaction, k, of 150 pounds per cubic inch (pci) can be used for design of these features. Slab reinforcement should consist of a minimum of 6 x .- 6 - 6/6 welded wire mesh (flat sheets) placed at slab mid-height to resist crack separation. Additional reinforcement should be placed as required by the structural engineer. 51-594701/511IR605.doc Copyright 2001 Kleinfelder, Inc. Page 14 of 24 scptmbn 12.2M)I . KLEINFELDER Since clays with lower subgrade modulus are present at depths below 2 feet of existing grade, a modulus of subgrade reaction of 100 pci should be used for the design of concrete slabs on relatively undisturbed terrace deposits that will be located at an elevation deeper than 1.5 feet below existing site grades. Concrete reinforcement should be placed in accordance with the recommendations of the structural engineer. ,- 5.3.3 Buried Structures Buried structures are considered those which have foundations bottomed 5 feet or more below existing site grade. Based upon the proposed depth of approximately 10 to 12 feet, it is likely the buried structures for this project will be supported upon terrace deposits. Buried structures should be supported entirely on terrace deposits where possible. Existing fill should be removed beneath the foundations and slabs of these structures. If engineered fill is required beneath the structures, the fill thickness should be uniform. This may require over-excavation of terrace deposits in localized areas. Foundations for deep structures can be designed using an allowable bearing pressure of 4,000 psf. A one-third increase can be applied when considering the total of all loads, including wind or seismic forces. Foundations should be a minimum of 12 inches wide and be bottomed a minimum of 12 inches below the lowest adjacent inside grade. - Passive resistance can be calculated using the equivalent fluid pressure of 325 pcf. A fiction factor of 0.30 can be used. An appropriate factor of safety, as described above, should be applied to passive pressure and fictional resistance. 5.4 LATERAL EARTH PRESSURES Lateral pressures acting against retaining walls can be calculated assuming that the backfill soils act as a fluid. The equivalent fluid weight (efw) value would depend on allowable wall movement. Walls which are free to rotate at least 0.5 percent of the wall height can be designed for the active efw. Walls which are restrained at the top or are sensitive to movement and tilting should be designed for the at-rest efw. Values given in the table below are in terms of equivalent fluid weight and assume a triangular distribution. These values assume that on-site imported, non-expansive sandy soils (SP, SM, SC) will be used as backfill and that the backfill is level and well drained above the static water table; ” the on-site clay soils should not be used as wall backfill. 51-594701/51 I IR60S.doc Copjright 2001 Klcinfcldcr, hc. Page IS of 24 September 12.2001 . KLEINFELDER .- Equivalent Fluid Weights (efw) For Calculating Lateral Earth Pressures Conditions Below Water Table* Above Water Table* At-Rest 85 40 Active 90 60 *The native water table is expected to be below the maximum depth of excavation; however, if the backfill is not provided with a drainage system, and there is a likely potential for the baclrfill to become saturated, then the ehv for a “below” water table condition should be considered. Fifty and thirty percent of any uniform areal surcharge placed at the top of the wall may be assumed to act as a uniform horizontal pressure over the entire wall for the at-rest and active cases, respectively. As a minimum, we recommend that a traffic surcharge equivalent to 2 feet of soil backfill be assumed as a surcharge for the at-rest condition. For this condition a pressure of 120 psf may be assumed to act as a uniform horizontal pressure over the entire height of the wall, H. We should be contacted where point or line loads are expected so we can provide recommendations for additional wall stresses. Walls should be provided with drains to reduce the potential for build-up of hydrostatic pressure. A typical drainage system could consist of a one- to two-foot-wide zone of Caltrans Class 2 permeable material immediately adjacent to the wall with a perforated pipe at the base of the permeable material. The pipe should be discharged to an appropriate outlet which is protected against erosion. Drainage fabrics could also be used. The geotextile manufacturer’s recommendations should be followed for installation of a drainage fabric system. .- Also, permanent walls should also be designed for seismic loading. The incremental dynamic earth pressure in psf for the at-rest case should be equivalent to 23H and 27.5H for the lower level earthquake event and upper level earthquake event, respectively (see Appendix C for description of these earthquake events). Allowable bearing pressure values described in previous sections of this report can be increased by one-third when calculating resistance caused by loads of short duration, such as earthquake loads. Restraining passive pressure and fiction values should not be increased by this amount, but a lower factor of safety that is normally applied to static loads could be used. This factor of safety for dynamic load conditions should not be less than 1.2. Backfill retaining walls should consist of predominately granular materials from on-site excavations or imported fill. Expansive soils present in the existing boring locations between 2 and 12 feet below the ground surface should not be used as backfill. All backfill should be placed in 8-inch loose lifts, 51-594701/5111RM)S.doc Copynght 2001 Kleinfelder, Inc. Page 16 of24 scptmba 12,2001 KLEINFELDER /" moisture-conditions to 2 percentage points above optimum moisture content, and compacted to at least 90 percent relative compaction. Wall backfill should be compacted by mechanical methods to at least 90 percent relative compaction in accordance with ASTM D 1557. For all retaining walls, we recommend a minimum horizontal distance kom the outside base of the footing to daylight of 5 feet for slopes of less than 20 feet in height, and 10 feet for slopes of greater heights. 5.5 SOIL PARAMETERS FOR USE IN PIPE DESIGN We recommend the following soil parameters for use in pipe design: Total weighty = 130 pcf Modulus of soil reaction, E' = 750 psi 5.6 SEISMIC DESIGN CONSIDERATIONS 5.6.1 Seismic Hazard Evaluation Appendix C contains a site specific seismic hazard analysis for the Encina Water Pollution Control Facility located directly adjacent to the north and east of the Carlsbad Water Recycling Facility. Due to the proximity of the two properties and the fact that both are underlain by the same geologic materials, the information in Appendix C can also be used for this current project. 5.6.2 UBC Seismic Design Parameters ," The site is within a Uniform Building Code QJBC) Near-Some Zone for active faults, and is within Seismic Zone 4. The following table includes the seismic design parameters for the site as defined in the 1997 edition of the UBC. Seismic Design Parameters - 51-594701/5111R605.doc Copyright 2001 Kleinfeldcr, Inc. Page I7 of 24 September 12,200 I . KLEINFELDER _I If any irregular or complex structures are planned, a seismic response spectra with damping would be required. This information is found in Appendix C. 5.7 PAVEMENT SECTIONS For purposes of analysis and design of pavements, we performed an R-value test on a selected soil sample considered representative of subgrade materials on-site. Our test results indicate that on-site subgrade soils have an R-value of 13. Actual pavement recommendations should be based on R-value tests performed on bulk samples of the soils that are exposed at the finished subgrade elevations across the site at the completion of the mass grading operations. 5.7.1 Flexible Pavements Flexible pavement sections have been evaluated in general accordance with the Caltrans method for flexible pavement design. Traffic indices of 4.5, 5.0, 6.0, 6.5 and 7.0 were used to facilitate the design of driveways and parking areas. Recommended flexible pavement sections for these " conditions are given in the following table: Flexible Pavement Sections Traffic Index Asphalt Concrete (inches) (inches) Aggregate Base 4.5 7 3 6.5 15.5 3 7.0 14 3 Flexible pavements should be constructed in accordance with current Caltrans Standard Specifications. Aggregate base should comply with the Caltrans Standard Specifications of Section 26. Aggregate base should be compacted to a minimum of 95 percent relative compaction (ASTh4 D 1557). 5.7.2 Rigid Pavement Portland cement concrete pavement (PCCP) may be desirable at entry points, trash collection - areas, and other locations where tight-tuming heavy vehicles are expected. For moderate commercial usage, we recommend a 6-inch thick rigid concrete pavement over 4 inches of 5l-S94701/5111R605.dw Copyright 2001 Kleinfeldcr. Inc. Page 18 of 24 septrmber 12.2OOl KLEINFELDER - aggregate base compacted to at least 95 percent relative compaction (ASTM D 1557). The subgrade beneath the aggregate base should be compacted to at least 95 percent relative compaction (ASTM D 1557). Aggregate base should comply with the specifications in Section 26 of Caltrans Standard Specifications. We recommend a 28-day compressive strength of at least 4,000 pounds per square inch for the pavement concrete mix design. The concrete mix should also be designed for a slump not exceeding 4 inches. Thickened edges should be used along outside edges of concrete pavements. Edge thickness should be at least 2 inches greater than the concrete pavement thickness and taper to the actual concrete pavement thickness 36 inches inward from the edge. Integral curbs may be used in lieu of thickened edges. Continuous sections of concrete pavement should be constructed in an approximately 12-foot square grid system or less. All longitudinal or transverse control joints should be constructed by saw-cutting, hand forming, or placing premolded filler such as zip strips. Longitudinal or transverse construction joints should be keyed or doweled to mitigate differential movement. 5.8 FLATWORK To reduce the potential manifestation of distress to exterior concrete flatwork due to movement of the underlying soil, we recommend that such flatwork be constructed with crack-control joints at appropriate spacing as designed by the structural engineer. Subgrade should be prepared in accordance with the earthwork recommendations presented earlier in this report. Positive drainage should be established and maintained adjacent to flatwork. .- .- "" .. . 5.9 SITE DRAINAGE Final elevations at the site should be planned so that positive drainage is established around structures. Positive drainage is defined as a slope of 2 percent or more for a distance of 5 feet or more away from structure foundations. Roof gutters and downspouts should be installed on structures. Downspouts should discharge to controlled drainage systems. Parking areas should be sloped and drainage gradients maintained to carry all surface water off the site. Ponding should not occur on the site. Planters should be built so that water exiting from them will not seep into the foundation areas or beneath slabs and pavement. In any event, the maintenance personnel should be instructed to .-. limit irrigation to the minimum actually necessary to properly sustain the landscaping plants. Should excessive irrigation, waterline breaks, or unusually high rainfall occur, saturated zones 51-594701/5111R605.doe Copyright 2001 Kleinfelder, Inc. Page 19 of 24 September l2,ZOOl . KLEINFELDER ./- and perched groundwater may develop. Consequently, the site should be graded so that water drains away readily without saturating the foundation or landscaped areas. Potential sources of water, such as water pipes, drains, garden ponds, and the like, should be frequently examined for signs of leakage or damage. Any such leakage or damage should be repaired promptly. 5.10 PRELIMINARY CORROSIVE SOIL SCREENING The corrosivity of the on-site materials was analyzed to evaluate its effect on concrete and ferrous metals. The corrosion potential was evaluated using the results of laboratory testing on one representative soil sample obtained during our subsurface evaluation. Laboratory testing was performed to evaluate pH, minimum electrical resistivity, and chloride and soluble sulfate content. The sample had a measured pH of 8.9, which is considered slightly basic. The sample had a measured minimum electrical resistivity of 668 ohm-cm, and a chloride content of 0.005 percent, which is considered mildly corrosive to ferrous metals. Testing also indicated a soluble sulfate content of 0.006 percent, which is considered negligibly corrosive to concrete. - Concrete in contact with soil or water that contains high concentrations of soluble sulfates can be subject to chemical deterioration. Based on the UBC criteria (UBC, 1997), the potential for sulfate attack is negligible for water-soluble sulfate contents in soil ranging from 0.00 to 0.10 percent by weight (0 to 1,000 ppm), and moderate for water-soluble sulfate contents ranging from 0.10 to 0.20 percent by weight (1,000 to 2,000 ppm). The potential for sulfate attack is severe for water-soluble sulfate contents ranging from 0.20 to 2.00 percent by weight (2,000 to 20,000 ppm) and very severe for water-soluble sulfate contents over 2.00 percent by weight (greater than 20,000 ppm). Laboratory testing indicated a sulfate content of approximately 0.006 percent (60 ppm), which is considered negligible for sulfate attack. Based on the laboratory test result, we recommend that Type LI cement be used for concrete structures in contact with soil. Our corrosion screening tests are preliminary in nature. Additional sampling and testing should . be performed after completion of grading. We recommend that a qualified corrosion engineer . 1 evaluate the general corrosion potential with respect to construction materials at this site. The ,.I corrosion test results are included in Appendix B. / \ '. -h Y ~. 51-594701/5IIIR605.doc Copyright 2001 Kleinfelder, he.

The borings were advanced to depths ranging from 2 1.5 to 25 feet below existing grades. Figure 2 presents the approximate locations of the borings. The Logs of Borings are presented as Figures A3 through A5. A Unified Soil Classification System (USCS) chart and a Boring Log Legend are presented as Figures A1 and 'A2, respectively. The Logs of Borings describe the earth materials encountered, samples obtained, and show field and laboratory tests performed. The logs also show the general location, boring number, drilling date, and the names of the logger and drilling subcontractor. The borings were logged by an engineer using the USCS. The boundaries between soil types shown on the logs are approximate because the transition between different soil layers may be gradual. Bulk and intact samples of representative earth materials were obtained from the borings. The exploratory borings were advanced using an hgersoll-Rand A300 truck-mounted drill rig, equipped with 8-inch-diameter hollow-stem augers. All borings were backfilled using the soil - from cuttings and tamped when the drilling and excavating was completed. In-place soil samples were obtained at the test boring locations using a California penetration sampler driven a total of 18-inches (or until practical refusal), into the undisturbed soil at the bottom of the boring. The soil sampled by the California sampler (3-inch O.D., 2.4 inches LD.) was retained in 6-inch long brass tubes for laboratory testing. An additional 2-inches of soil from each drive remained in the cutting shoe and was usually discarded after visually classifyng the soil. The samplers were driven using a 140 pound hammer falling 30-inches. The total number of hammer blows required to drive the sampler the final 12-inches is termed the blow count and is recorded on the Logs of Borings. Please note that these blow counts have not been adjusted for the effects of overburden pressure, input driving energy, rod length, sampler correction, or boring diameter correction. ,- 51-594701/51 I IR6OS.doc Copyright 2001 Kleinfeldcr, Inc.

INTRODUCTION This section presents the results of our site specific seismic hazard analysis for the proposed Encina wastewater treatment plant in Carlsbad, California. The subsurface soil conditions used in this study were obtained from our current geotechmcal investigation at the proposed site. The purpose of this ground motion study is to develop site specific ground motion criteria in terms of peak ground accelerations and design response spectra for the subject site by using a seismic source model (proximity to active faults, major historical earthquakes, regional seismicity) and subsurface soil conditions at the site. The response spectra is a graphical representation relating the maximum response of a single degree of freedom, elastic damped oscillator with different fundamental periods to dynamic loads. Site-specific spectra for any given return period represents uniform-risk earthquake ground motions consistent with the seismic source model and the local site response. Specifically, our scope of services include the following: Discussion of significant faults and assessment of site seismicity; Performance of seismic risk analyses to estimate the probability of occurrence of various levels of peak horizontal and vertical ground surface accelerations during the economic life of structure. Development of site-specific, uniform-risk horizontal response spectra for two levels of earthquake and four levels of damping. II. PROJECT LOCATION The project is located in Carlsbad, California. Using the USGS 7 1/2-minute topographic map of Encina quadrangle, the site coordinates are: Latitude: 33.1 15" N Longitude: 1 17.3 19" W ~. According to 1997 Uniform Building Code (UBC) Figure 16-2, the site lies within Seismic Zone 4. 5 1-5076-01 I 0 1999 Klcinfcldcr, Inc. KLEINFELDER - III. FAULTING The project site is in a region which is traditionally characterized by low to moderate seismic activity. The active Rose Canyon fault is located approximately 6.1 km to the southwest of the site. A major seismic event on this fault could cause significant ground shaking at the site. Other active faults that may result in significant ground shaking at the site include: the Newport- Inglewood fault (offshore), approximately 11.2 km to the northwest; the Coronado Bank Fault zone, approximately 32.3 km to the southwest; the Elsinore fault (Julian segment), approximately 40.6 km to the northeast; the Elsinore fault (Temecula segment), approximately 40.7 km to the northeast; the San Diego Trough approximately 46.7 km to the northeast; the Elsinore fault (Glen Ivy segment), approximately 58.8 km to the northeast; the Palos Verdes Fault zone, approximately 60.6 km to the northwest; the Earthquake Valley fault, approximately 69.1 km to the east; the San Jacinto fault (ha segment), approximately 78.3 km to the northeast; the Newport-Inglewood fault (onshore), approximately 78.4 km to the northwest; the San Jacinto fault (San Jacinto Valley segment), approximately 78.9 km to the northeast; the Chino - Central Ave. fault, approximately 82.5 km to the northwest; the San Jacinto fault (Coyote Creek segment), approximately 84.4 km to the northeast; the Whinier Fault, approximately 87.3 km to +- the northwest; the Elsinore fault (Coyote Mountain segment), approximately 90.8 km to the southeast; the Campton Blind Thrust , approximately 94.0 km to the northeast; and the Elysian Park Blind Thrust, approximately 99.0 km to the northwest. Based on the information provided in Hart and Bryant (1997), the site is not within an Alquist-Priolo Earthquake Fault Zone. Table 1 lists these faults and their seismic parameters. Locations of the active and potentially active faults in the area with respect to the subject site are shown on Plate 1. The locations of the faults and associated parameters presented on Table 1 are based on data presented by Wesnousky (1986), Petersen and Wesnousky (1994), Jennings (1994), Working Group on California Earthquake Probabilities (1995), Lindvall and Rockwell (1995), Petersen et. al. (1996). and Frankel et. al. (1996). The maximum earthquake magnitudes presented in this table are based on the moment magnitude scale developed by Kanamori (1 977). .- 5 1-50764 I 2 (D 1999 Kleinfelder. Inc .

Inc KLEINFELDER rc IV. SEISMICITY The project site and its vicinity are located in an area traditionally characterized by low seismic activity. Most of the high seismic activities are associated with the San Jacinto fault and Newport-Inglewood fault zones which are less than 100 km towards the northeast and northwest from the site, respectively. Some of the significant nearby events (less than 60 km) include: the November 22, 1800 (M6.5) San Diego Region earthquake, about 15 km towards the southeast; the May 27, 1862 (M6) earthquake associated with the Rose Canyon fault system, about 43 km towards the southeast; the October 23, 1894 (M5.8) earthquake, about 60 km towards the southeast, and the July 13, 1986 (M5.4) Oceanside earthquake, about 55 km toward the southwest associated with San Diego Trough fault zone. A background seismicity is included in our model to compensate for the lack of local faults. Epicenters of some significant earthquakes (M>4.0) within the vicinity of the site are shown on Plate 1. The earthquake data base used contains in excess of 5,500 seismic events and covers the period from 1800 through October 1998. The earthquake data base is principally comprised of an earthquake catalog for the State of California prepared by the Division of Mines and Geology I (CDMG). The original CDMG catalog (Real, et. al, 1978) is a merger of the University of California at Berkeley and the California Institute of Technology instrumental catalogs (Hileman, et. al, 1973). The combined catalog contains earthquake records from January 1, 1900 through December 31, 1974. Updates prepared by CDMG in 1979 and 1982 extend the coverage through 1982. In addition to the CDMG updates, the data for more recent earthquakes for the period between December 1974 and October 1998 have been obtained from several other sources, including the California Institute of Technology, the University of California at Berkeley, the University of Nevada at Reno, the Earthquake Data Base System of the U. S. Geological Survey, and the Council of the National Seismic System (CNSS). The CNSS catalog is world-wide earthquake catalog which is created by merging the master earthquake catalogs from contributing CNSS member networks and then removing duplicate events, or non-unique solutions from the same event. The CNSS network includes Northern and Southem California Seismic Networks, Pacific Northwest Seismic Network, University of Nevada, Reno Seismic Network, University of Utah Seismographic Stations and US National Earthquake Information Service. The earthquake data base also consists of earthquake records between 1800 and 1900. This subset of the earthquake data base was derived from Seeburger and Bolt (1976) and Toppozada, et. al(1978, 1981). 51-5076-01 4 0 1999 Klcinfcldcr, Inc. KLEINFELDER -- The parameters used to define the limits of the historical earthquake search include geographical limits (within 100 km of the site), dates (1800 through October 1998), and magnitudes (M>4). A summary of the results of the historical search is presented below. Time Period (1800 to October 1998) 198+ years Maximum Magnitude 7 Approximate distance to nearest historical earthquake 12.5 km Number of events exceeding magnitude 4 within search area 183 V. SITE CHARACTERIZATION In developing site specific seismic design criteria, the characteristics of the soils underlying the site are an important input to evaluate the site response at a given site. Primarily the project site consists of fill underlain by bedrock. The bedrock is primarily Marine deposit consisting of interbedded layers of moderately to highly weathered sanddstone and siltstone. The thickness of Marine deposit is greater than 50, we have classified the site as a soft rock. - the fill material varies up to about 25 feet. Since the average blow count in top 30 meters of the Based on the above information, we classify the site as site profile type SC based on the new NEW site classification according to Table 16-J of the 1997 Uniform Building Code (UBC) (1997 UBC, Rinne. 1994; Martin and Dobry, 1994). SC is defined as a soil profile consisting of very dense soils and soft rock with shear wave velocity between 360 and 760 m/s or SPT N > 50, or Su > 2000 psf. The site can also be classified as Site Class B according to Boore et. al. (1993, 1994). Site Class B is defined as a site having average shear wave velocities between 360 m/s (1200 feetkec) and 750 m/s (2500 feetkec) in the upper.30 m (100 feet). VI. SEISMIC RiSK ANALYSIS Based on the project design criteria provided by Montgomery Watson, we have developed peak ground accelerations for two levels of earthquakes. An Lower Level Event (LLE) is defined as the ground motion that has a 10% probability of exceedance in 50 years (return period of about 475 years) and an Upper Level Event (ULE) is defined as the ground motion that has a 10% probability of being exceeded in 100 years (return period of about 950 years). 5 1-5076-01 5 0 1999 Kleinfcldcr, Inc. KLEINFELDER ," A probabilistic seismic hazard analysis was used to estimate the peak ground accelerations for the LLE and ULE discussed above. This analysis involves the selection of an appropriate predictive relationship to estimate the ground motion parameters, and, through probabilistic methods, determination of peak accelerations. A. Attenuation Relationship Site-specific ground motions can be influenced by the styles of faulting, magnitudes of the earthquakes, and local soil conditions. The attenuation relationships used to estimate ground motion from an earthquake source needs to consider these effects. Many attenuation relationships have been developed to estimate the variation of peak ground surface acceleration with earthquake magnitude and distance from the site to the source of an earthquake. Of these relationships, we have selected the relationship presented by Boore et. a1 (1993,1994) because of its wide acceptance by seismologists. This relationship has also been used in developing recent Interim National Seismic Hazard Maps (Frankel et. al., 1996) for the State of California. Since the site can be classified as Site Class B according to Boore et. al. (1993, 1994), we have used the relationship that corresponds to the Site Class B. However, the relationship by Boore et. al. .- (1993, 1994) does not provide spectral values for periods greater than 2 seconds. Therefore, to develop response spectra for long periods, we have used the relationship presented by Abrahamson and Silva (1993). These predictive relationships were developed from statistical analyses of recorded earthquakes from Western North America, including the records from the 1989 Loma Prieta earthquake and 1992 Landers earthquake. The attenuation relationships provide mean values of ground motions associated with one set of parameters: magnitude, distance, site soil conditions, and mechanism of faulting. The uncertainty in the predicted ground motion is taken into consideration by including a magnitude dependent standard emor in the probabilistic analysis. B. Probabilistic Analysis Probabilistic modeling procedure was used to estimate the peak ground motions corresponding to the two levels of earthquakes. The probabilistic analysis approach is based on the characteristics of the earthquake and of the causative fault associated with the earthquake. These characteristics include such items as magnitude of the earthquake, distance from the site to the causative fault, maximum credible earthquake, length, and activity of the fault. The effects of site soil conditions and mechanism of faulting are accounted for in the attenuation relationships. .-. 5 1-5076-01 6 0 1999 Kleinfcldcr. Inc. KLEINFELDER - The theory behind the seismic risk analysis has been developed over many years (Cornell, 1968, 1971; Merz and Cornell, 1973) and is based on the "total probability theorem" and on the assumption that earthquakes are events that are independent of time and space from one another. According to this approach, the probability of exceeding PE(Z) at a given level of ground motion, Z, at the site within a specified time period, T, is given by where 9(Z) is the mean annual rate of exceedance of ground motion level Z. Different probabilities of exceedance may be selected, depending on the level of performance required. C. Peak Ground Acceleration Based on the results of our seismic analyses, the calculated peak ground horizontal accelerations (in units of gravity) for both LLE and ULE are presented in Table 2 below. This table also presents the peak vertical ground accelerations (in units of gravity) for both LLE and ULE estimated using data presented by Niazi and Bozorgnia (1991, 1992). The corresponding return period and annual probabilities of occurrence are also shown in Table 2. c TABLE 2: PEAK GROUND ACCELERATION Event Peak Vertical Peak Horizontal Probability of Annual Probability Retum Period (Years) Acceleration (g) Acceleration (9) Occurrence of Exceedance LLE 0.44 0.50 10% in 50 0.0022 475 years ULE 0.54 0.60 10% in 100 0.001 1 950 D. Design Response Spectra The site-specific design response spectra for this project were developed based on a uniform-risk approach. The uniform risk approach assumes that the same level of risk is uniformly applied to the entire response spectra. Response spectral values for the two levels of ground motions and four levels of damping were calculated using the same probabilistic analysis approach, described above. The predictive relationship for pseudo-relative velocity response spectra (horizontal component) by Boore, Joyner, and Fumal(l993, 1994) was used to attenuate the ground motions from the source to site. 5 1-5076-0 I 7 0 1999 Klcinfcldcr. Inc. . KLEINFELDER ..- The resulting uniform -risk response spectra in linear form are presented on Plates 2 and 3 and in tripartite form are presented on Plates 4 and 5. The spectral acceleration values (in units of gravity) for the two levels of ground motions and for four levels of damping are also listed on Table 3. TABLE 3: SITE SPECIFIC SPECTRAL ACCELERATION (9) .- ,-- 5 1-5076-01 0 1999 Kleinfeldcr, Inc. KLEINFELDER ..” E. Dynamic Earth Pressure In addition to the active or at rest soil pressure, the tank walls at the proposed facility should be designed for the incremental dynamic earth pressures. These incremental dynamic earth pressures depend on the expected peak ground accelerations, the nature of the backfill, and the type of wall. The results of our analyses for both, flexible walls which are free to rotate at the top, and stiff walls which are restrained at the top, are presented below. Flexible walls are those that are free to rotate at the top with wall movement at the top exceeding 0.5% of H, where H is the wall height. The incremental dynamic earth pressure for the design of the flexible walls under seismic conditions were calculated for both the Lower Level and Upper Level of Earthquakes using the method proposed by Mononobe-Okabe (1929). Assuming a backfill unit weight of 125 pcf, the incremental dynamic earth pressures (APE) at the proposed site in pounds per square foot are 1 1.5H and 14.5H for LLE and ULE events, respectively. These incremental pressures should be applied uniformly over the wall height, H, where H is in feet. Similarly, the incremental dynamic earth pressure for the design of stiff walls (defined as having wall movement at the top being restricted and between 0.2% and 0.5% of H) for the proposed facility under seismic conditions were calculated for both levels of earthquakes using the method proposed by Yong (1985). The incremental dynamic earth pressures (APE) for the stiff walls at the proposed site in pounds per square foot are 23H and 27.5H for LLE and ULE events, respectively. These incremental pressures should be applied uniformly over the wall height, H, where H is in feet. .- F. Spectral Velocity We have estimated the spectral velocities for a probable tank sloshing period of about 2.5 seconds with % percent damping using spectral plots presented on Plates 6 and 7 for UE and ULE events, respectively. According to these plots the spectral velocities for LLE and ULE are 38 idsec and 51 idsec, respectively. G. Near Fault Issues in Structural Design In recent years, many modem structures located near the seismic source have been severely damaged or have collapsed. The severe damage and/or collapse is attributed to near fault motions that are characterized by energetic unidirectional velocity pulses (Singh 1984, 1985). - What makes these motions particularly damaging is the impulse (area under the acceleration multiplied by the mass). A structural system that yields during a long duration pulse (impulse SI-5076-01 9 0 1999 Klcinfclder, Inc. . KLEINFELDER .- loading) may experience very large permanent deformations andor collapse. The extent of these actions depends on the strength and natural period of the structure and the structure articulation, as well as the amplitude, duration, and shape of the pulse. The near fault pulse type motions can be particularly damaging because they can accumulate inelastic deformations in one direction and their considerations in the near fault conditions should be properly evaluated. Due to'the close distance between the Rose Canyon fault and the site, near source effects should be considered in the structural desipg of the proposed facility. Structures with strength discontinuities, soft stories, plan irregularities, discontinuous shear walls and ductile moment frames are vulnerable to these types of motions. The impact of the near fault aspects on the response spectrum have been included in our analysis. Therefore, the accelerations presented in this analysis include near fault factors. .- 5 1-5076-01 IO 0 1999 Kleinfelder. Inc KLEINFELDER ,- VII. REFERENCES Abmhamson, N.A. and Silva, W.J.

All oversize rocks and boulders that cannot be incorporated in the work by placing in embankments or used as rip-rap or for other purposes shall be removed from the site by the Contractor. 3.3 Treatment of Exposed Surface - The ground surface exposed by excavation shall be scarified to a depth of 6 inches, moisture conditioned to the proper moisture content for compaction and compacted as required for compacted fill. Compaction shall be approved by the Geotechnical Engineer prior to placing fill. 3.4 Rock Excavation - Where solid rock is encountered in areas to be excavated, it shall be loosened and broken up so that no solid ribs, projections or large fragments will be within 6 inches of the surface of the final subgrade. 4.0 COMPACTED FILL ,- 4.1 Materials - Fill material shall consist of suitable on-site or imported soil. All materials used for structural fill shall be reasonably free of organic material, have a Expansion Index of 50 or less, IOOYO passing the 3 inch sieve and less than 30 percent passing the #200 sieve. 4.2 Placement - All fill materials shall be placed in layers of 8 inches or less in loose thickness and uniformly moisture conditioned. Each lift should then be compacted with a sheepsfoot roller or other approved compaction equipment to at least 90 percent relative compaction in areas under structures, utilities, roadways and parking areas. No fill material shall be placed, spread or rolled while it is frozen or thawing, or during unfavorable weather conditions. 4.3 Compaction Equipment - The Contractor shall provide and use sufficient equipment of a type and weight suitable for the conditions encountered in the field. The equipment shall be capable of obtaining the required compaction in all areas. 4.4 Recomoaction - When, in the judgment of the Geotechnical Engineer, sufficient compactive effort has not been used, or where the field density tests indicate that SIJ94701A111R605.doc Copyright 2001 Klcinfeider, Inc. D-3 September 12,2001 KLEINFELDER .- the required compaction or moisture content has not been obtained, or if pumping or other indications of instability are noted, the fill shall be reworked and recompacted as needed to obtain a stable fill at the required density and moisture content before additional fill is placed. 4.5 Resuonsibilitv - The Contractor shall be responsible for the maintenance and protection of all embankments and fills made during the contract period and shall bear the expense of replacing any portion which has become displaced due to carelessness, negligent work or failure to take proper precautions. 5.0 UTILITY TRENCH BEDDING AND BACKFILL L 5.1 5.2 Material - Pipe bedding shall be defined as all material within 4 inches of the perimeter and 12 inches over the top of the pipe. Material for use as bedding shall be clean sand, gravel, crushed aggregate or native free-draining material, having a Sand Equivalent of not less than 30. Backfill should be classified as all material within the remainder of the trench. Backfill shall meet the requirements set forth in Section 4.2.6 for compacted fill. Placement and Comoaction - Pipe bedding shall be placed in layers not exceeding 8 inches in loose thickness, conditioned to the proper moisture content for compaction and compacted to at least 90 percent relative compaction. All other trench backfill shall be placed and compacted in accordance with Section 306-1.3.2 of the Standard Specifications for Mechanically Compacted Backfill. Backfill shall be compacted as required for adjacent fill. If not specified, backfill shall be compacted to at least 90 percent relative compaction in areas under structures, utilities, roadways, parking areas and concrete flatwork. 6.0 SUBSURFACE DRAINAGE 6.1 General - Subsurface drainage shall be constructed as shown on the plans. Drainage pipe shall meet the requirements set forth in the Standard Specifications. 6.2 Materials - Permeable drain rock used for subdrainage shall meet the following gradation requirements: 51-594701/5111R605.doc Copyright 2001 Kleinfelds, Inc.
