's (Petra's) geotechnical investigation of the subject property. The purposes of this investigation were to determine the nature of surface- and subsurface-soil conditions a nd to evaluate their in-place characteristics; provide geotechnical recommendations with respect to site grading; and for design and construction of building foundations. This investigation also included a review of published and unpublished literature, as well as geotechnical maps pertaining to active and potentially active faults that lie in proximity to the site. Location and Site Description The subject site, which is currently vacant, is located in the City of Temecula, California. The site is bordered on the north by Overland Drive; the south by Solana Way and automobile dealerships; the east by Margarita Road; and on the west by Ynez Road. The general location of the site is shown on Figure 1. The irregular-shaped property consists of a gently sloping area of land throughout much of the site with existing desilting basins excavated in the western and southern portions of the site. Elevations vary from approximately 1,048 feet above sea level in the central portion of the site to approximately 1,100 feet above sea level along the east-central portion of the site. Gradients on the site range from generally 3 percent to nearly vertical, with 0.5: I (horizontal:vertical [h:v)) cut slopes descending into the desilting basin in the southern portion of the site. Drainage is generally towards the west to southwest. tt1~ ~ ,I I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 2 Underground structures known to be present within the site consist of a storm drain along the western portion of the site immediately west and north of the adjacent automobile dealerships. A storm-drain inlet was observed in the far western desilting basin near Solana Way. Corrugated-metal pipes, 2-foot in diameter, were observed from the northwestern desilting basins to the adjacent flood-control channel. Vegetation within the site consists of sparse weeds and grass throughout much of th e site with large bushes and riparian vegetation within some of the desilting basins. Fan palms and deciduous trees were observed on the east-central portion of the site. Proposed Development/Grading The enclosed 100-scaJe topographic map (Plate I) indicates that the proposed development will consist of five level-graded pads intended for commercial/industrial structures and associated access roads. Maximum proposed cuts and fill are approximately 12 and 21 feet, respectively. Proposed maximum cut-and fill-slope height are approximately 15 feet at a gradient of2:1 (h:v). Purpose and Scope of Services The purposes of this study were to obtain information on the subsurface conditions within the project area, evaluate the data, as well as provide conclusions and recommendations for design and construction of the proposed structures, as influenced by the subsurface conditions. ~ tti ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 3 The scope of our investigation consisted of the following. .

These photographs, obtained from Riverside County Flood Control, are at scales ranging from 1 inch is equal to 1,600 feet to 1 inch is equal to 2,000 feet. A review of select aerial photographs indicated the site was in a relatively natural condition in the 1962 photos. The 1974 photos revealed four residences in the ea st- central portion of the site with the remainder of the site being utilized for agriculture. A livestock farm was observed in the northeastern portion of the site, near the intersection of Overland Drive and Margarita Road. In 1980, two desilting basins had been added to the previous development, one along the channel in the northwestern portion of the site and the other in the southwestern portion of the site along Solana Way. By 1983, additional desilting basins had been constructed along the channel. The 1990 photographs indicated development south of Solana Way and along Motor Car Parkway was underway. The second desilting basin along Solana Way near the intersection of Margarita Road and Solana Way had been constructed and appeared to have sand bags placed on the slope face descending into the basin from the north. A fill area located to the north of that desilting basin was observed that corresponds to fill shown on our geotechnical map (Plate I). By 1995, the single-family residences and farm had been removed and the site left vacant. New development observed in the 2000 photos consists of a rip-rap-lined channel improvement along the northwestern site boundary. A discussion of the lineament observed in our aerial-photo review is contained within the Faulting Section of this report.

The following reports were reviewed. . SoilTech Inc. (] 987) - A preliminary geotechnical investigation was performed by SoilTech, Inc. (SoiITech) for the auto-mall development along Motor Car Parkway immediately west of the site. Their investigation included an II-foot- deep fault trench in the southeastern portion of the site. SoilTech did not report any evidence of faulting associated with Kennedy's lineament in the referenced report. . Aragon Geotechnical Consultants (988) - A fault investigation by Aragon Geotechnical Consultants (Aragon) was performed southeast of the intersection of Ynez Road and Solana Way immediately south of the subject site. Aragon did not report any evidence of faulting in connection with Kennedy's lineament within their excavations summarized in the referenced report. Field Exploration Subsurface exploration was performed on December 16, 18 and 25, 2000, and on January 25, 2001, the excavation of 17 test pits to depths ranging from 2.5 to 9 feet utilizing a rubber-tired backhoe. ACME 55 drill rig equipped with an automatic 140-pound hammer was used to drill five exploratory borings to depths varying between 21.5 and 51.5 feet. Prior to subsurface work, an underground utilities clearance was obtained from Underground Service Alert of Southern California. Earth materials encountered within the exploratory test pits and borings were classified and logged in accordance with the visual-manual procedures of the Unified Soil Classification System. The approximate locations of the test pits and exploratory borings are shown on Plate 1 and descriptive logs are presented in Appendix A. co ~ ~ I I I I I 1/ __H I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 6 Associated with the subsurface exploration was the collection of bulk (disturbed) samples and relatively undisturbed samples of soil for laboratory testing. Undisturbed samples were obtained using a 3-inch-outside-diameter modified California split-spoon soil sampler lined with brass rings. The soil sampler was driven mechanically with successive 30-inch drops of an automatic, gravity-driven, 140-pound hammer. The central portions of the driven-core samples were placed in sealed containers and transported to our laboratory for testing. Laboratory Testing Maximum dry density, expansion potential, soluble-sulfate analysis and shear strength of undisturbed samples were determined for selected disturbed (bulk) and undisturbed samples of soil and bedrock materials considered representative of those encountered. Moisture content and unit dry density were also determined for in- place soil and bedrock materials in representative strata. A brief description of laboratory test criteria is given in Appendix B and all test data are summarized on Plates B-1 through B-2. In-situ moisture content and dry unit weight are included in the exploration logs (Plates A-I through A- 28, Appendix A). An evaluation of the test data is reflected throughout the Conclusions and Recommendations Section of this report. FINDINGS Regional Geologic Setting The site is located within the Peninsular Range Geomorphic Province 0 f California. The Peninsular Ranges are characterized by steep, elongated, northwest-trending valleys. More specifically, the site is located on the southwest portion of the Perris Block which is bounded on the north by the San Gabriel and Cucamonga faults, on ~ ~ ~ . I. I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 7 the east by the San Jacinto fault, on the west by the Elsinore Trough and on the south by an undefined zone south of Temecula. The Perris Block is predominately composed of crystalline granitic basement complex of Cretaceous-age with Quaternary sediment accumulations in low-lying areas. The crystalline basement complex forms well-rounded hills of moderate relief. Sparse volcanic units of Tertiary-age occur in the western portion of the Perris Block. Local Geology and Soil Conditions Locally, the site is located on the western end of a northwest-trending ridge of Paub a formational sandstone. The gently west-sloping site has been modified by intermittent grading operations which have created desilting basins and storm dra ins to accommodate surface flow as the land surrounding the site has been developed. The grading has resulted in five desilting basins cut into the existing bedrock and areas of undocumented artificial fill near the basins. The majority of the site, away from the basins, appears to be in a relatively natural condition. The individual units are discussed below. . Undocumented Artificial Fill (map symbol: Afu) - Undocumented artificial fill was encountered in several areas throughout the site - in the far north-central portion it was observed forming berms and access roads which separated the three desilting basins; forming the western slope of the northernmost basin; and thin (approximately 2-foot thick) wedges 0 f fill observed southeast of the basins within the terraced hillside. The artificial fill in this area consisted of locally derived soils and was predominately silty sand which was dry, loose and heav ily burrowed. A 2.5-foot-thick organic layer was observed within Test Pit TP-l and appeared to be isolated within the fill berm. Artificial fill was also observed in the east-central portion of the site in the vicinity of a tree-lined, level-graded pad. It appears that the pad was created by cutting the far eastern portion and pushing the cut material to the western margins of the pad. It consisted of dry, medium dense silty sand. The upper 1 foot was extensively burrowed and rutted with tire tracks. tt1'P ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 200 I J.N.452-00 Page 8 The third area in which artificial fill was observed was within the southeastern portion of the site immediately north of the two desilting basins along Solana Way. The fill consisted of dry to damp silty sand which was loose to medium dense and had small (less than 6 inches) pieces of asphaltic concrete and other construction debris. An organically stained layer was observed at the contact between the fill and underlying native soil. Therefore, no clearing or grubbing operations were performed prior to the fill placement. The fill appears to have been derived by the excavation of the nearby desilting basins. Within the western portion of the site, undocumented fill was noted within all th e test pits (TP-18 through TP-23) ranging from approximately 2 to 3 feet in depth. A stockpile of rip-rap-sized boulders were noted within this area near the drainage channel and Ynez Road (see Plate I). Several small piles of end-dumped fill and construction debr is were observed on the site and are noted on the enclosed geotechnical map (Plate 1). . Ouaternary Pauba Formational Bedrock (map symbol: Ops) - The entire site is underlain by relatively horizontally bedded siltstone and sandstone of the Pauba Formation. Silty sands predominate; however, beds of silt, well-graded and poorly graded sands were also encountered in the subsurface investigation. A thin veneer of recent alluvium was encountered within the desilting basins. However, due to its thickness (generally 1 foot), it is not differentiated from the Pauba Formation in this report. The silty sands were generally moist and medium dense to dense. While the Pauba Formation is classified as bedrock, the sandstone and siltstone units more closely resemble soils in their characteristics. Accordingly, these materials have been described in accordance with the Unified , Soil Classification System in the logs presented in Appendix A. The upper 3 feet of the silty sandstone was often dry and cemented. A very coarse-grained clayey sand layer was observed within Borings B-2 and B-4, it was orange, moist, medium dense, with some manganese staining. Poorly and well-graded sand layers were encountered 10 to 20 feet below the surface within our borings. The sands were moist to very moist, medium dense, nonindurated, with iron and manganese staining. A micaceous silt was encountered within the borings at depth and was observed near the surface within the desilting basins adjacent to Solana Way. The silt was olive, locally massive, moist to wet, stiff to very stiff and occasionally iron-stained. \\ ~ ~ I I I I I il I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 9 Groundwater Seepage was encountered within Boring B-1 at 14 feet. The seepage was occurring along a sand layer adjacent to the flood-control channel. No other seepage or groundwater was encountered within excavations throughout the rest of the site. Based on local well data and on our ~xperience in the area, groundwater within the Pauba Formation is approximately 38 feet below the ground surface. Faulting The geologic structure of the entire southern California area is dominated mainly by northwest-trending faults associated with the San Andreas system. Faults, such as the Newport-Inglewood, Whittier, Elsinore, San Jacinto and San Andreas, are major faults in this system and all are known to be active. In addition, the San Andreas, Elsinore and San Jacinto faults are known to have ruptured the ground surface in historic times. Based on our review of published and unpublished geotechnical maps and literature pertaining to site and regional geology, the closest active faults to the site are the Elsinore fault located approximately 0.2 kilometer to the west; the Murrieta fault located approximately 5.5 kilometers to the north; and the Wolf Valley fault located approximately 7.3 kilometers to the south. The most significant fault, with respect to anticipated ground motions at the site, is the Elsinore fault, due to its proximity and large possible magnitude. Kennedy (1977) mapped a northwest-trending lineament through the subject site. The 1.38-kilometer-Iong lineament was noted due to the northwest-trending breaks in topography which parallel the Wildomar branch of the Elsinore fault. An aerial- photograph review was performed in an effort to gain additional information to \'V ~ ~ IllnJ;)W;).1/I;)J.llld lIlP.l;)WWO;) ;).lJV-LE: ANVdJi\lO;) ONV A'I1TI I'I3 01 ;Jjj'ed OO-Z~V 'N'f TOOZ 'n hJenuef 'jj'UPlnel ljl!M p;Jle!JOSSe S!

This method thus accounts for the likelihood (rather than certainty) of occurrence and provides levels of ground acceleration that might be more reasonably hypothesized for 'a finite-exposure period. Moreover, the State of California has adopted the standard of using peak -ground acceleration exceeded at a 10 percent probability in 50 years, also known as "Design-Basis Earthquake Ground Motion", in seismic analysis per requirement of the 1997 Uniform Building code (UBC) Sections 1627,1629.1 and 1631.2. Our probabilistic analysis was performed by utilizing computer program "FRISKSP" (Blake, 1998) and adopting the attenuation relationship for soil published by Boore, et al. (see Blake, 1995). The results indicate the design-basis earthquake ground motion for the site is 0.46g for peak-ground acceleration with a 10 percent probability of being exceeded within a 50-year period. The results of our deterministic and probabilistic analysis are included In Appendix C of this report. CONCLUSIONS AND RECOMMENDATIONS General From a soils engineering and engineering geologic point of view, the subject property is considered suited for the proposed construction, provided the following conclusions and recommendations are incorporated into the design criteria and project specifications.

Specifications All earthwork and grading should be performed in accordance with all applicable requirements of the Grading and Excavation Code and the Grading Manual of the County of Riverside, California, in addition to the provisions of the 1997 UBC, including Chapter 16 and Appendix A33. Grading should also be performed in accordance with applicable provisions of the attached Standard Grading Specifications (Appendix D) prepared by Petra, unless specifically revised or amended herein. Clearing and Grubbing All weeds, grasses, brush, shrubs and trees in areas to be graded shall be stripped and hauled offsite. Trees to be removed should be grubbed-out such that their stumps and major-root systems are also removed and the organic materials hauled offsite. During site grading, laborers should clear from fills any roots, tree branches and other deleterious materials missed during clearing and grubbing operations. It is assumed that proposed grading will render the existing storm drain obsolete. Therefore, the storm drain and the surrounding fill materials should be removed. Clearing operations should also include the removal of all trash and debris existing within areas of proposed construction and/or grading. The project soils engineer or his qualified representative should be notified at the appropriate times to provide observation and testing services during clearing operations to verify compliance with the above recommendations. In addition, any buried structures, unusual or adverse soil conditions encountered that are not \~ tt1 ~ I I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N. 452-00 Page 13 described or anticipated, herein should be brought to the immediate attention of the geotechnical consultant. Excavation Characteristics Based on the results of our exploratory borings and test pits, residual soil materials and other surficial deposits (i.e., alluvium and undocumented fill) will be readily excavatable with conventional earthmoving equipment. Bedrock materials will be excavatable with moderate ripping. Groundwater Localized seepage will likely be encountered adjacent to the flood-control channel in the western portion of the site. Ground Preparation - Fill Areas All existing low-density and potentially collapsible-soil materials, such as loose ffianmade fill, alluvium and highly weathered bedrock, will require removal to underlying dense bedrock from each area to receive compacted fill. Prior to placing structural fill, exposed bottom surfaces in each removal area should be scarified to a depth of 12 inches or more, watered or air-dried as necessary to achieve near optimum moisture conditions and then recompacted in-place to a minimum relative density of 90 percent. Based on test pits, borings and laboratory testing, anticipated depths of removals range from 2 to 9 feet and are shown on the enclosed geotechnical map (Plate 1). However, actual depths and horizontal limits of removals will have to be determined during grading on the basis of in-grading inspections and testing performed by the project soils engineer and/or engineering geologist. \(" ~ ~ I I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 14 Fill Placement All fill should be placed in 6- to 8-inch-thick-maximum lifts, watered or air-dried as necessary to achieve uniform near optimum moisture conditions and then compacted in-place to a minimum relative density of 90 percent. The laboratory maximum dry density and optimum moisture content for each change in soil type should be determined in accordance with ASTM Test Method D1557-91. Benching Compacted fills placed against natural-slope surfaces inclining at 5: 1 (h:v) or greater should be placed on a series of level benches excavated into competent bedrock. Benching will also be required where compacted fills are placed against temporary backcuts of recommended buttress fills and shear keys. Typical benching details are shown on Plates SG-3, SG-4, SG-S, SG-7 and SG-8 (Appendix D). Import Soils for Grading In the event import soils are needed to achieve final-design grades, all potential import materials should be free of deleterious/oversize materials, be non-expansive and approved by the project soils engineer prior to being brought onsite. Processing of Cut Areas Where low-density surficial deposits of topsoil, existing fill and/or alluvium are not removed in their entirety in cut areas (building pads and driveways), these materials will require overexcavation and replacement as properly compacted fill. Cut/Fill Transition Lots To minimize the detrimental effects of differential settlement, cutlfill transitions should be eliminated from all building areas where the depth of fill placed within the \"\ ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 15 "fill" portion exceeds proposed footing depths. This should be accomplished by overexcavating the "cut" portion and replacing the excavated materials as properly compacted fill.

Shallow FiIl-to-Deep-FiIl Lots To mitigate the potential adverse effects of differential settlement on fill lots underlain with substantial differences in compacted fill depths, the "shallow" fill portions should be overexcavated to maintain the minimum fill depths recommended in the preceding section. Shrinkage, Bulking and Subsidence V olumetric changes in earth quantities will occur when excavated onsite soil and bedrock materials are replaced as properly compacted fill. Following is an est imate of shrinkage and bulking factors for the various geologic units present onsite. These estimates are based on in-place densities of the various materials and on the estimated average degree of relative compaction achieved during grading. .'\~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 16 .

Bulking 0 to 3 % Subsidence from scarification and recompaction of exposed bottom surfaces in removal areas to receive fill is expected to vary from negligible to approximately 0.1 foot. The above estimates of shrinkage, bulking and subsidence are intended as an aid for project engineers in determining earthwork quantities. However, these estimates should be used with some caution since they are not absolute values. Contingenci es should be made for balancing earthwork quantities based on actual shrinkage and subsidence that occurs during the grading operations. Cut Slopes Cut slopes planned throughout the development are expected to be grossly stable to the maximum height (15 feet) and at the maximum-planned inclination of 2: I (h:v). It is assumed that the 0.5: I (h:v) cut slopes along Margarita Road and Solana Way will be regraded to 2: 1 (h:v). In-grading observation of individual cut slopes will be required by the project engineering geologist to confirm favorable-geologic structure of the exposed bedrock. Where highly fractured bedding, out-of-slope bedding, seepage or non-cemented-sand strata are observed, the cut slopes in question may require stabilization by means of a compacted buttress or stabilization fill. Stability of Temporarv Backcut Slopes The stability of temporary backcut slopes is dependent on many factors which include slope angle, height, geologic structure of unsupported bedrock, shear \0, ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26,2001 J.N.452-00 Page 17 strength along planes of weakness, groundwater conditions, nuisance water and the length of time temporary cuts remain unsupported. Consequently, there is always a risk of backcut failure during excavation of basal-fill keys. However, this risk may be reduced by the following. . Excavating and filling basal-fill keys in the shortest practical period of time (keyway excavations should never be allowed to stand open for prolonged periods of time, such as over weekends and holidays). . Restricting operation of heavy-grading equipment and other construction vehicles on or near the tops of temporary slopes. . Preventing nuisance water and rainwater from collecting and ponding in keyway excavations. In addition to the above, all OSHA requirements should be followed with respect to excavation safety. Fill Slopes Fill slopes, including stabilization-fill slopes constructed with onsite soil and/or bedrock materials, will be grossly and surficially stable to the heights and at the inclinations planned. Fill slopes should be constructed as recommended below. A fill key excavated a minimum depth of 2 feet into competent bedrock will be required at the base of all fill slopes. The width of the fill key should equal one-hal f the slope height or 15 feet, whichever is greater. Typical fill-key construction details are shown on Plates SG-3 and SG-7 (Appendix D). To obtain proper compaction to the face of fill slopes, low-height fill slopes should be overfilled and backfilled during construction and then trimmed-back to the compacted inner core. Where this procedure is not practical for higher slopes, fina I .1P ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 18 surface compaction should be obtained by backrolling during construction to achieve proper compaction to within 6 to 8 inches of the finish surface, followed by rolling with a cable-lowered sheepsfoot and grid roller. A basal 15-foot-wide fill key excavated into competent terrace deposits or bedrock will be required at the base of all fill slopes proposed on existing ground surfaces inclining at 5: 1 (h:v) or greater. Typical details for construction of the basal-fill key are shown on Plate SG-3 (Appendix D). FilI-Above-Cut and Cut-to-Fill Transition Slopes Where fill-above-cut slopes are proposed, a 15-foot-wide key excavated into competent bedrock should be constructed at the contact. The bottom of the key should be tilted-back into the slope at a minimum gradient of 2 percent. A typical section for construction of fill-above-cut slopes is shown on Plate SG-7 (Appendix D) The lower cut portion of the slope should be excavated to grade and observed by the project engineering geologist prior to constructing the fill portion. Where cut-to-fill transition slopes are proposed, the fill portion should be placed on a series of benches excavated into competent natural ground or bedrock. The benches should be at least 8 to 10 feet wide, constructed at vertical intervals of approximately 5 feet and tilted-back into the slope at a minimum gradient of 2 percent. Where cuHo-fill transition contacts vary from about vertical to a few degrees from vertical, benching of the fill portion into the cut portion, as recommended above, will be difficult and may create a potential slip surface due to inadequate benching. Therefore, overexcavation of the cut portion and reconstruction of the entire slope with compacted fill is recommended. ?) ~ ~ I I I i I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 LN. 452-00 Page 19 Geotechnical Observations An observation of clearing operations, removal of unsuitable-surficial materials, cut- and fill-slope construction and general grading procedures should be performed by the project geotechnical consultant. Fills should not be placed without prior approval from the geotechnical consultant. The project geotechnical consultant or his representative should be present onsite during all grading operations to verify proper placement and compaction of fill, as well as to verify compliance with the other recommendations presented herein. Post-Grading Considerations Slope Landscaping and Maintenance Adequate slope and pad drainage facilities are essential in the design of grading for the subject site. An anticipated rainfall equivalency on the order of 60 to 100:1: inches per year at the site can result due to irrigation. The overall stability of the graded slopes should not be adversely affected provided all drainage provisions are properly constructed and maintained thereafter and provided all engineered slopes are landscaped with a deep-rooted, drought-tolerant and maintenance-free plant species, as recommended by the project landscape architect. Additional comments and recommendations are presented below with respect to slope drainage, landscaping and irrigation. A discussion of pad drainage is given in a following section. The most common type of slope failure in hillside areas is the surficial type and usually involves the upper l' to 6:!: feet. For any given gradient, these surficial slope failures are generally caused by a wide variety of conditions, such as overwatering; cyclic changes in moisture content and density of slope soils from .,;v 1ti ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 20 both seasonal and irrigation-induced wetting and drying; soil expansiveness; time lapse between slope construction and slope planting; type and spacing of plant materials used for slope protection; rainfall intensity; and/or lack of a proper maintenance program. Based on this discussion, the following recommendations are presented to mitigate potential surficial slope failures. . Proper drainage provisions for engineered slopes should consist of concrete terrace drains, downdrains and energy dissipaters (where required) constructed in accordance with the Grading Code of the City of Temecula. Provisions should also. be made for construction of compacted-earth berms along the tops 0 f all engineered slopes. . All permanent engineered slopes should be landscaped as soon as practical at th e completion of grading. As noted, the landscaping should consist of a deep- rooted, drought-tolerant and maintenance-free plant species. If landscaping cannot be provided within a reasonable period of time, jute matting (or equivalent) or a spray-on product designed to seal slope surfaces should be considered as a temporary measure to inhibit surface erosion until such time permanent landscape plants have become well-established. . Irrigation systems should be installed on the engineered slopes and a watering program then implemented which maintains a uniform, near optimum moisture condition in the soils. Overwatering and subsequent saturation of the slope soils should be avoided. On the other hand, allowing the soils. to dry-out is also detrimental to slope performance. . Irrigation systems should be constructed at the surface only. Construction of sprinkler lines in trenches should not be allowed without prior approval from the soils engineer and engineering geologist. . During construction of terrace and downdrains, care must be taken to avoid placement of loose soil on the slope surfaces. . A permanent slope-maintenance program should be initiated for major slopes not maintained by individual owners. Proper slope maintenance must include the care of drainage- and erosion-control provisions, rodent control and repair of leaking or damaged irrigation systems. iP ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 21 , . Provided the above recommendations are' followed with respect to slope drainage, maintenance and landscaping, the potential for deep saturation of slope soils is considered very low. . Owners should be advised of the potential problems that can develop when drainage on the pads and slopes is altered in any way. Drainage can be altered due to the placement of fill and construction of garden walls, retaining walls, walkways and planters. Utility Trenches All utility-trench backfill within street right-of-ways, utility easements, under sidewalks, driveways and building-floor slabs, as well as within or in proximity to slopes should be compacted to a minimum relative density of 90 percent. Where onsite soils are utilized as backfill, mechanical compaction will be required. Density testing, along with probing, should be performed by the project soils engineer or his representative, to verify proper compaction. For deep trenches with vertical walls, backfill should be placed in approximately 1- to 2-foot-thick maximum lifts and then mechanically compacted with a hydra- hammer, pneumatic tampers or similar equipment. For deep trenches with sloped- walls, backfill materials should be placed in approximately 8- to 12-inch-thick- maximum lifts and then compacted by rolling with a sheepsfoot tamper or similar equipment. As an alternate for shallow trenches where pipe may be damaged by mechanical compaction equipment, such as under building-floor slabs, imported clean sand having a sand equivalent value of 30 or greater may be utilized and jetted or flooded into place. No specific relative compaction will be required; however, observation, probing and, if deemed necessary, testing should be performed. 7..~ ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-oo Page 22 To avoid point-loads and subsequent distress to clay, cement or plastic pipe, imported sand bedding should be placed at least I foot above all pip e in areas where excavated trench materials contain significant cobbles. Sand-bedding materials should be thoroughly jetted prior to placement of backfill. Where utility trenches are proposed parallel to any building footing (interior and/or exterior trenches), the bottom of the trench should not be located within a 1: 1 (h:v) plane projected downward from the outside bottom edge of the adjacent footing. Site Draina!!e Positive-drainage devices, such as sloping sidewalks, graded-swales and/or area drains, should be provided around each building to collect and direct all water awa y from the structures. Neither rain nor excess irrigation water should be allowed to collect or pond against building foundations. Roof gutters and downspouts may be required on the sides of buildings where yard-drainage devices cannot be provided and/or where roof drainage is directed onto adjacent slopes. All drainage should be directed to adjacent driveways, adjacent streets or storm-drain facilities. Seismic Design Considerations Ground Motions Structures within the site should be designed and constmcted to resist the effects of seismic ground motions as provided in 1997 UBC Sections 1626 through 1633. The method of design is dependent on the seismic zoning, site characteristics, occupancy category, building configuration, type of stmctural system and building height. Seismic design coefficients were determined using UBCSElS, a computer program developed by Thomas F. Blake (UBCSEIS, 1998). This program compiles fault information for a particular site using a modified version of a data file of / 7,? ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 200 I J.N.452-00 Page 23 approximately 183 California faults that were digitized by the California Department of Mines and Geology and the U.S. Geological SurVey. Various data are computed for a particular site, including the distance of the site from each of the faults in the data file, the estimated slip-rate for each fault and the "maximum moment magnitude" of each fault. The program then selects the closest Type A, Type B and Type C faults from the site and computes the seismic design coefficients for each of the fault types. The highest computed seismic design coefficients are the selected as the design coefficients for the subject site. Based on the computer analysis, the Wildomar fault of Elsinore fault zone (located less than 1 kilometer from the site) would probably generate the most severe site ground motions with an anticipated maximum moment magnitudes of 6.8 and anticipated slip rate of 5.0 mrnlyear. The following 1997 UBC seismic design coefficients have been determined for this fault and are recommended for use in the design of the proposed structures. These seismic design coefficients are based on the soil-profile type as determined by existing subsurface geologic conditions, the proximity of the site to the Wildomar fault and on the maximum moment magnitude and slip rate of the nearby fault. Parameters for structures founded on either bedrock or fill materials are presented in the following table. 16-1 Seismic Zone Factor Z 16-U Seismic Source Type 16-J Soil Profile 16-S Near~Source Factor NJ 16-T Near-Source Factor Nv 16-Q Seismic Coefficient Ca 16-R SeismIC Coefficient Cv OAO B SD 1.3 1.6 OA4N" = 0.57 O,64N" ~ 1.02 1J.. ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N.452-00 Page 24 Secondary Effects of Seismic Activity Secondary effects of seismic activity normally considered as possible hazards to a site include several types of ground failure, as well as induced flooding. Various general types of ground failures which might occur as a consequence of severe ground shaking at the site include landsliding, ground subsidence, ground lurching, shallow-ground rupture and liquefaction. The probability of occurrence of each type of ground failure depends on the severity of the earthquake, distance from faults, topography, subsoils and groundwater conditions, in addition to other factors. All of the above secondary effects of seismic activity are considered unlikely at the si te. Seismically induced flooding which might be considered a potential hazard to a site normally includes flooding due to a tsunamis (seismic sea wave), a seiche (i.e., a wave-like oscillation of the surface of water in an enclosed basin that may be initiated by a strong earthquake) or failure of a major reservoir or retention structure upstream of the site. Since the site is located nearly 25 miles inland from the nearest coastline of the Pacific Ocean at an elevation in excess of 1,000 feet above mean sea level, the potential for seismically induced flooding due to a tsunamis run- up is considered nonexistent. Since no enclosed bodies of water lie adjacent to the site, the potential for induced flooding at the site due to a seiche is also considered nonexistent. Tentative Foundation-Design Recommendations General Provided site grading is performed in accordance with the recommendations of this report, conventional shallow foundations are considered feasible for support of the proposed structures. Tentative foundation recommendations are provided herein. ~1 ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 25 However, these recommendations may require modification depending on as-graded conditions existing within the building sites upon completion of grading. Allowable-Bearing Values An allowable-bearing value of 1,500 pounds per square foot (pst) may be used for 24-inch-square pad footings and 12-inch-wide continuous footings founded at a minimum depth of 12 inches below the lowest adjacent final grade. This val ue may be increased by 20 percent for each additional foot of width and/or depth, to a maximum value of 2,500 psf. Recommended allowable-bearing values include both dead and live loads and may be increased by one-third for short-duration wind and seismic forces. Settlement Based on the general settlement characteristics of the compacted fill and in-situ bedrock, as well as the anticipated loading, it has been estimated that the maximum total settlement of conventional footings will be less than approximately 0.75 inch. Differential settlement is expected to be about one-half the total settlement. It is anticipated that the majority of the settlement will occur during construction or shortly thereafter as building loads are applied. The above settlement estimates are based on the assumption that the grading will be performed in accordance with the grading recommendations presented in this report and that the project geotechnical consultant will observe or test the soil conditions in the footing excavations. Lateral Resistance A passive earth pressure of 250 psf per foot of depth to a maximum value of 2,500 psf may be used to determine lateral-bearing resistance for footings. In addition, a 1-" ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N.452-00 Page 26 coefficient of friction of 0.4 times the dead-load forces may be used between concrete and the supporting soils to determine lateral sliding resistance. The above values may be increased by one-third when designing for short-duration wind or seismic forces. The above values are based on footings placed directly against compacted fill. In the case where footing sides are formed, all backfill placed against the footings should be compacted to a minimum of 90 percent of maximum dry density. Footing Setbacks From Descending Slopes . Fill Slopes -- Where structures are proposed near the tops of descending compacted fill slopes, the footing setbacks from the slope face should conform with 1997 UBC Figure 18-1-1. The required minimum setback is H/3 (one-third the slope height) measured along a horizontal line projected from the lower outside face of the footing to the slope face. The footing setbacks should be 5 feet minimum where the slope height is 15 feet or less and vary up to 40 feet maximum where the slope height exceeds 15 feet. . Cut Slopes -- Where structures are proposed near the tops of descending cut slopes composed of sound granitic bedrock materials, the footing setbacks from the slope face should also generally conform with 1997 UBC Figure 18-1-1; however, the maximum footing setback may be reduced to 15 feet in-lieu of 40 feet where the slope height exceeds 15 feet. Building Clearances From Ascending Slopes Building setbacks from ascending cut and fill slopes should conform with 1997 UB C Figure 18-1-1 that requires a building clearance of H/2 (one-half the slope height) varying from 5 feet minimum to 15 feet maximum. The building clearance is measured along a horizontal line projected from the toe of the slope to the face of the building. A retaining wall may be constructed at the base of the slope to achieve the required building clearance. ~o.. tti ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 27 Footing Observations All building-footing trenches should be observed by the project geotechnical consultant to verify that they have been excavated into competent bearing soils. The foundation excavations should be observed prior to the placement of forms, reinforcement or concrete. The excavations should be trimmed neat, level and square. All loose, sloughed or moisture-softened soil should be removed prior to concrete placement. Excavated materials from footing excavations should not be placed in slab-on-grade areas unless the soils are compacted to a minimum of 90 percent of maximum dry density. Expansive Soil Considerations Results of preliminary laboratory tests indicate onsite soil and bedrock materials exhibit a VERY LOW expansion potential as classified in accordance with 1997 UBC Table l8-I-B; however, expansive soil conditions should be evaluated for individual lots during and at the completion of rough grading to verify the anticipated condition. The design and construction details presented below may be tentatively considered for conventional footings and floor slabs underlain with non- expansive foundation soils but subject to possible modification depending on actual as-graded soil conditions. Furthermore, it should be noted that additional slab thickness, footing sizes and/or reinforcement more stringent than the minimum recommendations that follow should be provided as recommended by the project architect or structural engineer. ~o tt1 ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N. 452-00 Page 28 Very Low Expansion Potential (Expansion Index of 20 or less) Results of preliminary laboratory tests by Petra, Leighton and Soil Tech indicate onsite soil and bedrock materials exhibit a VERY LOW expansion potential as classified in accordance with 1997 UBC Table 18-I-B; however, expansive soil conditions should be evaluated for individual building sites during and at the completion of rough grading to verify the anticipated condition. The design and construction details that follow may be tentatively considered for conventional footings and floor slabs underlain with non-expansive foundation soils; however, the following recommendations may be subject to modification depending on actual as- graded soil conditions. Furthermore, it should be noted that additional slab thickness, footing sizes and/or reinforcement more stringent than the minimum recommendations that follow should be provided as recommended by the project architect or structural engineer. Since actual structural details are unknown at the present time, two sets of recommendations have been prepared depending on the proposed construction. These include office, retail and commercial structures of wood-frame and/or masonry construction and commercial structures of concrete tilt- up construction. . Office. Retail and Commercial Structures of Wood-Frame and/or Masonry Construction Footings Exterior and interior continuous footings may be founded at the minimum depths indicated in UBC Table IS-I-O (i.e:, 12-inch minimum depth for one- story construction and IS-inch minimum depth for two-story construction). All continuous footings should have a minimum width of 12 and 15 inches, for one- and two-story buildings, respectively and reinforced with a minimum of two No.4 bars, one top and one bottom. - Interior isolated pad footings should be a minimum of 24 inches square and founded at minimum depths of 12 and IS inches below the lowest adjacent final '?' ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 29 grade for one- and two-story construction, respectively. The pad footings should be reinforced with No.4 bars spaced a maximum of IS inches on centers, both ways, near the bottoms of the footings. - Exterior isolated pad footings intended for support of roof overhangs, such as second-story decks, patio covers and similar construction, should be a minimum of 24 inches square and founded at a minimum depth of 18 inches below the lowest adjacent final grade. The pad footings should be reinforced with No. 4 bars spaced a maximum of 18 inches on centers, both ways, near the bottoms of the footings. . Floor Slabs - Building floor slabs constructed on-grade should be a nominal 4 inches thick and reinforced with 6-inch by 6-inch, No.6 by No.6 welded-wire fabric or with No.3 bars spaced 24 inches on centers, both ways. All slab reinforcement should be supported on concrete chairs or bricks to ensure the desired placement near mid-depth. - Concrete floor slabs in areas to receive carpet, tile or other moisture-sensitive coverings should be underlain with a moisture vapor barrier consisting of a polyvinyl chloride membrane such as 6-mil Visqueen or equivalent. The membrane should be properly lapped, sealed and protected with at least 2 inches of clean sand. It is cautioned that slabs in areas to receive ceramic tile or other rigid, crack-sensitive floor coverings must be designed and constructed to minimize hairline cracking. Extra reinforcing and careful control of concrete slump to minimize concrete shrinkage are recommended. If floor slabs are constructed before building construction is completed, block- outs should be provided around interior columns to permit relative movement and mitigate possible distress to the floor slabs due to differential settlement that will occur between pad footings and adjacent floor subgrade soils as building loads are applied. - The concrete contractor and underground subcontractors should be prohibited from placing excess soils derived from footing and utility-trench excavations on slab-an-grade areas unless the soils are compacted to a minimum of 90 percent of maximum dry density. ~'t- ~ ~ I I I I I I I I I I II I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 30 - Prior to placing concrete, subgrade soils below slab-on-grade areas should be thoroughly watered to achieve a moisture content that is at least equal or slightly greater than optimum moisture content. This moisture content should penetrate to a minimum depth of 12 inches into the sub grade and maintained in the subgrade soils during concrete placement to promote uniform curing of the concrete and minimize the development of shrinkage cracks. . Concrete Tilt-Up Structures Footin~s Exterior and interior continuous footings may be founded at the minimum depths indicated in 1997 UBC Table l8-I-B (i.e., l2-inch minimum depth for one-story construction and IS-inch minimum depth for two-story construction). All continuous footings should have a minimum width of 12 and 15 inches, for one- and two-story buildings, respectively. - Where exterior pad footings are used for wall support in lieu of continuous footings, the tops of the footings should be founded at a depth of 12 inches below the lowest adjacent final grade. In order to minimize water from infiltrating subgrade soils below slabs-on-grade, pad footings should be joined with continuous grade beams or wall panels should extend below grade and rest on top of the footings. The effect of wall loads on pad footings should be considered in design of pad footings. - Exterior isolated pad footings (intended for support of roof overhangs or similar structural features) and interior isolated pad footings should be a minimum 24 inches square and founded at a minimum depth of 18 inches below the lowest adjacent final grade. All continuous footings and grade beams should be reinforced with two No.4 bars, one top and one bottom. . Interior and exterior pad footings should be reinforced with No.4 bars spaced IS inches on centers, both ways, near the bottoms of the footings. Floor Slabs In passive-use areas, building floor slabs constructed on-grade should be a nominal 4 inches thick and reinforced with 6-inch by 6-inch, No.6 by No.6 welded-wire fabric or with No.3 bars spaced 24 inches on centers, both ways. ?j!J ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N. 452-00 Page 31 All slab reinforcement should be supported on concrete chairs or bricks to ensure the desired placement near mid-depth. - Where floor slabs are to be subjected to heavy floor loads and/or traffic loading, such as forklifts, especially those with hard rubber wheels, the performance of the floor slab is critical with respect to movements between adjacent slab areas and spalling of joints. Proper design and construction to provide shear transfer between adjacent slab units and proper joint details is critical to proper service of these floors. The project structural engineer should be consulted regarding the design of the slab thickness, reinforcing and joint design spacing and details for these slab areas. Proper control of concrete slump and curing to minimize slab "curling" and the resultant voids under the slab is also critical. - Concrete floor slabs in areas to receive carpet, tile or other moisture-sensitive coverings, should be underlain with a moisture vapor barrier consisting of a polyvinyl chloride membrane such as 6-mil Visqueen or equal. The membrane should be properly lapped, sealed and protected with at least 2 inches of sand. I! is cautioned that slabs in areas to receive ceramic tile or other rigid, crack- sensitive floor coverings must be designed and constructed to minimize hairline cracking. Extra reinforcing and careful control of concrete slump to minimize concrete shrinkage are recommended. - If floor slabs are constructed before building construction is completed, block- outs should be provided around interior columns to permit relative movement and minimize possible distress to the floor slabs due to differential settlement that will occur between pad footings and adjacent floor subgrade soils as building loads are applied. The concrete contractor and underground subcontractors should be prohibited from placing excess soils derived from footing and utility-trench excavations on slab-on-grade areas unless the soils are compacted to a minimum of90 percent of maximum dry density. Prior to placing concrete, the sub grade soils below slab-on-grade areas should be thoroughly watered to achieve a moisture content that is at least equal or slightly greater than optimum moisture content. This moisture content should penetrate to a minimum depth of 12 inches and maintained in the sub grade during concrete placement to promote uniform curing of the concrete and minimize the development of shrinkage cracks. 7J\ ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N. 452-00 Page 32 Preliminary Structural-Pavement Desh.!n R-value tests were not performed; however, based on Petra's experience on projects with similar soil and bedrock conditions, it is anticipated that the subgrade materials that will exist with the street areas at the completion of rough grading will exhibit R-values in excess of 10. Therefore, assuming a conservative R-value of 10 for street subgrade materials and considering Traffic Indices of 6.0 and 7.0 for collector streets, the following tentative pavement-design sections have been prepared for preliminary planning purposes. Collector streets 6.0 7.0 0.30 over 0.95 0.35 over 1.15 Collector streets Notes: AC = Asphalt Concrete (inches) AB = Aggregate Base (inches) Sub grade soils immediately below the AB should be compacted to a minimum of 95 percent relative compaction based on ASTM Test Method DI557 to a depth of 12 inches or more. Final subgrade compaction should be performed prior to placing AB and after all utility-trench backfills have been compacted and tested. AB materials should consist of Class 2 AB conforming to Section 26-1.02B of the State of California (Caltrans) Standard Speciftcations of either crushed AB, crushed miscellaneous base or processed miscellaneous base conforming to Section 200-2 of the Standard Specifications for Public Works Construction (Greenbook). AB materials should be compacted to a minimum of 95 percent relative compaction ,/ '?1'l> ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial ParcellTemecula January 26, 2001 J.N.452-00 Page 33 based on ASTM Test Method D1557. AC materials and construction should conform to Section 203 of the Greenbook. Concrete Ffatwork Thickness and Joint Spacing To reduce the potential of unsightly cracking, concrete sidewalks and patio-type slabs should be at least 3.5 inches thick and provided with construction or expansion joints every 6 feet or less. Concrete driveway slabs should be at least 4 inches thick and provided with construction or expansion joints every 10 feet or less. Subgrade Preparation As a further measure to minimize cracking of concrete flatwork, the subgrade soils below concrete-flatwork areas should first be compacted to a minimum relative density of 90 percent and then thoroughly wetted to achieve a moisture content that is at least equal or slightly greater than optimum moisture content. This moisture should extend to a depth of 12 inches below subgrade and maintained in the soils during placement of concrete. Pre-watering of the soils will promote uniform curing ofthe concrete and minimize the development of shrinkage cracks. A representative of the project soils engineer should observe and verify the density and moisture content of the soils and the depth of moisture penetration prior to placing concrete. Planters Area drains should be extended into all planters that are located within 5 feet of building walls, foundations, retaining walls and masonry-block garden walls to minimize excessive infiltration of water into the adjacent foundation soils. The surface of the ground in these areas should also be sloped at a minimum gradient of 2 percent away from the walls and foundations. Drip-irrigation systems are also ?P ~ ~ I I I I I II , !

Cement Type Soluble-Sulfate Aualvses Laboratory test data indicate site soils contain less than 0.1 percent water-soluble sulfates. Therefore, according to 1997 UBC Table 26-A -6, no special cement will be required for concrete to be placed in contact with onsite soils. GRADING-PLAN REVIEW AND CONSTRUCTION SERVICES This report has been prepared for the exclusive use of Eli Lilly and Company to assist the project engineer and architect in the design of the proposed development. It is recommended that Petra be engaged to review the final-design drawings and specifications prior to construction. This is to verify that the recommendations contained in this report have been properly interpreted and are incorporated in to the ' project specifications. If Petra is not accorded the opportunity to review these documents, we can take no responsibility for misinterpretation of our recommendations. We recommend that Petra be retained to provide soil-engineering services during construction of the excavation and foundation phases of the work, This is to observe compliance with the design, specifications or recommendations and to allow design changes in the event that subsurface conditions differ from those anticipated prior to start of construction. ~"\ ~ ~ I I I I I I I I I I I I I I I I I I I ELI LILLY AND COMPANY 37-Acre Commercial Parcel/Temecula January 26, 2001 J.N. 452-00 Page 35 If the project plans change significantly (e.g., building loads or type of structures), we should be retained to review our original design recommendations and their applicability to the revised construction.

The samples were re-examined in the laboratory and the classifications reviewed and then revised where appropriae. The assigned group symbols are presented in the baring and test pit logs. Appendix B. Laboratorv Maximum Drv Densitv Maximum dry density and optimum moisture content were determined for selected samples of soil and bedrock materials in accordance with ASTM Test Method DI557-91. Pertinent test values are given on Plate B-1. Exoansion Potential Expansion index tests were performed on selected samples of soil and bedrock materials in accordance with ASTM Test Method D4829-95. Expansion potential classitications were determined from UBC Table t8.1-B on the basis of the expansion index values. Test results and expansion potentials are presented on Plate B-1. Soluble Sulfate Chemical analyses were performed 011 selected samples of onsite soil to determine concentrations of soluble sulfate. This test was performed in accordance with Califomia Test Method No. 417. Test esults are included on Plate B-1. In-Situ Moisture and Densitv Moisture content and unit dry density of in-place soil and bedrock materials were "termined in representative strata. Test data is summarized in the boring and test pit logs, Appendix B. Direct Shear The Coulomb shear strength parameters. angle of internal friction and cohesion, were determined for undisturbed samples. and for samples remolded ta 90 percent of maximum dry density. These tests were performed in general accordance with ASTM Test Method D3080-72. Three specimens were prepared for each test. The test specimens were artiticially saturated, and then sheared under varied normal loads at a maximum constant rate of strain of 0.05 inches per minute.

I I No deviation from these specifications will be allowed, except where specifically superseded in the preliminary geology and soils report, or in other written communication signed by the Soils Engineer and Engineering Geologist. I. GENERAL I A. The Soils Engineer and Engineering Geologist are the Owner's or Builder's representative on the project. For the purpose of these specifications, supervision by the Soils Engineer includes that inspectian performed by any person or persons employed by, and responsible to, the licensed Civil Engineer signing the soils report. I B. All clearing. site preparation. or earthwork performed on the project shall be conducted by the Contractor under the supervision of the Soils Engineer. I C. It is the Contractor's responsibility to prepare the ground surface to receive the fills to the satisfaction of the Soils Engineer and to place, spread, mix, water, and compact the fill in accordance with the specifications of the Soils Engineer. The Contractor shall also remove all material considered unsatisfactory by the Soils Engineer. I I D. It is also the Contractor's responsibility to have suitable and sufficient compaction equipment on the job site to handle the amount of fill being placed. If necessary, excavation equipment will be shut down to permit completion of compaction. Sufficient watering apparatus will also be provided by the Contractor, with due consideration for the fill material, rate of placement. and time of year. I E. A final report shall be issued by the Soils Engineer and Engineering Geologist attesting to the Contractor's conformance \vith these specifications. I II. SITE PREPARATION I A. All vegetation and deleterious material such as rubbish shall be disposed of offsite. This removal shall be concluded prior to placing fill. I B. Soil, alluvium, or bedrock materials determined by the Soils Engineer as being unsuitable for placement in compacted fills shall be removed and wasted from the site. Any material incorporated as a part of a compacted fill must be approved by the Soils E ngi neer. I I C. After the ground surface to receive fill has been cleared, I shall be scarified, disced, or bladed by the Contractor until it is uniform and free from ruts, hollows, hummocks, or other uneven features which may prevent uniform compaction. I The scarified ground surface shall then be brought to optimum moisture, mixed as required. and compacted as specified. If the scarified zone is gre<ier than 12 inches in depth, the excess shall be removed and placed in lifts restricted to 6 inches. I I . Page 1 . ~ I I I I I I I I I I I I I I I I I I I STANDARD GRADING SPECIFICATIONS Prior to placing fill. the ground surface to receive fill shall be inspected, tested, and approved by the Soils Engineer. D. Any underground structures such as cesspools, cisterns, mining shafts, tunnels, septic tanks, wells, pipe lines, or others are to be removed or treated in a manner prescribed by the Soils Engineer. E. In order to provide uniform bearing conditions in cut/fill transition lots and where cut lots are partially in soil, colluvium, or unweathered bedrock materials, the bedrock portion of the lot extending a minimum of 3 feet outside of building lines shall be overexcavated a minimum of 3 feet and replaced with compacted fill. (Typical details are given on Plate SG-l.) III. COMPACTED FillS A. Any material imported or excavated on the property may be utilized in the fill, provided each material has been determined to be suitable by the Soils Engineer. Roots, tree branches, and other matter missed during clearing shall be removed from the fill as directed by the Soils Engineer. B. Rock fragments less than 6 inches in diameter may be utilized in the fill provided: 1. They are not placed in concentrated pockets. 2. There is a sufficient percentage of fine grained material to surround the rocks. 3. The distribution of rocks is supervised by the Soils Engineer. C. Rocks greater than 6 inches in diameter shall be taken offsite or placed in accordalce with the recommendations of the Soils Engineer in areas designated as suitable for rock disposal. (A typical detail far Rock Disposal is given in Plate SG-2.) D. Material that is spongy, subjectto decay, or otherwise considered unsuitable shall not be used in the compacted fill. E. Representative samples of materials to be utilized as compacted fill smll be analyzed by the laboratory of the Soils Engineer to determine their physical properties. If any material other than that previously tested is encountered during grading, the appropriate analysis of this material shall be conducted by the Soils Engineer as soon as possible. F. Material used in the compacting process shall be evenly spread, watered, processed, and compacted in thin lifts not to exceed 6 inches in thickness to obtain a uniformly dense layer. The fill shall be placed and compacted on a horizontal plane, unless otherwise approved by the Soils Engineer. G. If the moisture content or relative density varies from that required by the Soils Engineer, the Contractor shall rework the fill until it is approved by the Soils Engineer. - Page 2 - CV\ I I STANDARD GRADING SPECIFICATIONS I H. Each layer shall be compacted to 90 percent of the maximum density in compliance with the testing method specified by the controlling governmental agency. (In general. ASTM D 1557-78, the five-layer method, will be used,) I I If compaction to a lesser percentage is authorized by the controlling governmental agency because of a specific land use or expansive soils condition. the area to received fill compacted to less than 90 percent shall either be delineated on the grading plan or appropriate reference made to the area in the soils report. I I. All fills shall be keyed and benched through all topsoil, colluvium, alluvium or creep material, into sound bedrock or firm material where the slope receiving fill exceeds a ratio of 5 horizontal to 1 vertical, in accordance with the recommendations of the Soils Engineer. I J. The key for side hill fills shall be a minimum of 15 feet within bedrock or firm materials, unless otherwise specified in the soils report. i5ee detail on Plate 5G-3.l I I K. 5ubdrainage devices shall be constructed in compliance with the ordinances of the controlling governmental agency, or with the recommendations of the Soils Engineer or Engineering Geologist. (Typical Canyon Subdrain dellils are given in Plate SG-4.) I L. The contractor will be required to obtain a minimum relative compaction of 90 percent out to the finish slope face of fill slopes, buttresses, and stabilization fills. This may be achieved by either overbuilding the slope and cutting back to the compacted core, or by direct compaction of the slope face with suitable equipment, or by any other procedure which produces the required compaction. I M. All fill slopes should be planted or protected from erosion by other methods specifia:J in the soils report. I N. Fill-over-cut slopes shall be properly keyed through topsoil, colluvium or creep material into rock or firm materials, and the transition shall be stripped of all soils prior tq placing fill. (See detail on Plate 5G-7.) I IV. CUT SLOPES I A. The Engineering Geologist shall inspect all cut slopes at vertical intervals not exceeding 10 feet. I B. If any conditions not anticipated in the preliminary report such as perched water, seepage, lenticular or confined strata of a potentially adverse nature, unfavorably inclined bedding, ioints or fault planes are encountered during grading, these conditions shall be analyzed by the Engineering Geologist and Soils Engineer, and recommendations shall be made to treat these problems. (Typical details for stabilization of a portion of a cut slope are given in Plates SG-5 and SG-8.) I I C. Cut slopes that face in the same direction as the prevailing drainage shall be protecta:J from slope wash by a nonerodible interceptor swale placed at the top of the slope. I I . Page 3 - 0f6 I I STANDARD GRADING SPECIFICATIONS I D. Unless otherwise specified in the soils and geological report. no cut slopes shall be excavated higher or steeper than that allowed by the ordinances of controlling governmental agencies. I I E. Drainage terraces shall be constructed in compliance with the ordinances of controlling governmental agencies, or with the recommendations of the Soils Engineer or Engineering Geologist. I V. GRADING CONTROL A. Inspection of the fill placement shall be provided by the Soils Engineer during the progress of grading. I B. In general, density tests should be made at intervals not exceeding 2 feE! of fill height or every 500 cubic yards af fill placed. This criteria will vary depending on soil conditions and the size of the job. In any event, an adequate number of field density tests shall be made to verify that the required compaction is being achieved. I I C. Density tests should also be made on the surface material to receive fill as required by the Soils Engineer. I D. All cleanouts, processed ground to receive fill, key excavations, subdrains, and rock disposals must be inspected and approved by the Soils Engineer or Engineering Geologist prior to placing any fill. It shall be the Contractor's responsibility to notify the Soils Engineer when such areas are ready for inspection. I VI. CONSTRUCTION CONSIDERATIONS I A. Erosion control measures, when necessary, shall be provided by the Contractor during grading and prior to the completion and construction of permanent drainage controls. I B. Upon completion of grading and termination of inspections by the Soils Engineer, no further filling or excavating. including that necessary for footings, foundations, large tree wells, retaining walls, or other features shall be performed without the approval of the Soils Engineer or Engineering Geologist. I C. Care shall be taken by the Contractor during final grading to preserve any berms, drainage terraces, interceptor swales, or other devices of permanent nature on or adjacent to the property.

A design professional should select the appropriate pa~ement section based o~ t~e anticipated traffic conditions. Based on these deSIgn parameters, analYSIs. tn accordance with the current Cal-Trans Highway Design Manual, and assummg compliance with site preparation recommendations, TESD recommends the followingpavcment structural sections: 5.0 3.0 5.0 4.5 4.0 5,5 3.5 6.5 5.0 4.0 6.0 4.0 6,5 4.5 4.0 6.5 4.5 7.5 4.5 4,0 7.0 5.0 7,5 4.5 4.0 7.5 5.0 9.5 6.5 5.0 8.0 5.0 10.5 7.5 6,0 8.5 5.0 12,5 9.5 7,5 (I) (2) (3) (4) ^'PM1I ConCl<te; Crushed Aggregate B:ssc (CAB), Green nook !\CCticm 200-2-'-. compacted to at lca.."t 95% rel'l;vc c,""paction (ASThi 0-1557); Aprcpte Base ~ccrion utilizing TI:l1$aT BX 1100 gE:Ogrld inuaUed t\t the dc,ign subgradc elevation; Aggrcgtltc Sase ~tion tltiU~in!: Tcnl\u BX 1200 gcogrid installed at the design sul>~de elevation.

The aggregate base should conform to the Crushed Aggregate Base per Greenbaok requirements, Section 200-2.2. The base course should be compacted to a minimum dry density of 95% of the materials maximtUn density as determined by the ASTM Dl557 test procedure. Field testing should be used to verify compaction, aggregate gradation, and compacted thickness. \0\ '01/02/2004 18: 3& 858715.

The maximum lift thickness should be ,two inches. The asphalt concrete material shall conform to 1)pe m, Class C2 or C3, 1997 edition of the Greenbook Standard Specifications for Public Works Construction. An approved mix design should be submitted 30 days prior to placement, The mix design should include proportions of materials, maximum density and required lay-down temperature range. Field testing should be used to verify oil content, aggregate gradation, compaction, compacted thickness, and lay-down temperature. If the paved areas are to be used during construction, or if the type and frequency of traffic is greater than assumed in the design, the pavement section should be re- evaluated for the anticipated traffic. Rigid Portland Cement Concrete (PCC) Recommendations for Portland Cement Concrete (pCe) pavement structural sections are as follows: Parking stalls for light-weight 1 160 4.5 4.0 vehicles Driveways for light-weight 25 160 6.0 4.0 vehicles Driveways and parking areas 100 200 6.0 6.0 for heavy trucks (1) ADTT values htlVC been aaliumed for planning pu1l)OSes;md "bnutd be c;oofnmed 'by the dc.'dgn team dUrin~ future plan dc"ltI01'fl"lCTlt.

Construction jointing, doweling, and reinforcing should be provided in accordance with recommendations of the ACt Subgrade ,soil should be compacted to a minimum of 95 percent relative compaction for pavement constructed over low to medium expansive soils. Crush Aggregate Base (CAB) should oonform to section 200-2.2 of the Standard Specifications for Public Works Construction "Greenbook" and should be compacted to a minimum of 95 percent of the maximum dry density at near optimum moisture content. Where trash bin enclosures arc to be constructed, it is recommended to use a minimum PCC pavement section of 8 inches, or as required by the traffic design, whichever is greater; reinforced with No. 3 bars spaced at 12 inches in each horizontal direction. The concrete should extend into the roadway sufficiently so that the front wheels of the trash truck are on the concrete when loading. Rigid portland cement concrete sections were evaluated using methods suggested by the American Concrete Institute - Guide for Design and Construction of Concrete Parking Lots (ACI 330R-92). . The performance of pavements is highly dependent' upon providing positive surface drainage away from the edge ofthc pavement, The ponding of water on or adjacent to pavement areas will likely cause failure ofthe subgrade and resultant pavement distress. Where planters arc proposed, the perimeter curb should extend at least 6 inches below the subgrade elevation of the adjacent pavement. In addition, our experience indicates that even with these provisions, a saturated subgrade condition can develop as a result of increased irrigation, landscaping and surface \'\111off. A subdrainage system should be constructed. along the perimeter of:pavement sub grade areas to reduce the potential of this condition developing. The sudrain system should be designed to intercept irrigation water and surface runoff prior to entry into the pavement sub grade and carry the water to a suitable outlet. The details presented in this report are preliminary based on the information provided regarding the proposed construction, and the results of the field and preliminary laboratory testing, combined with interpolation of the subsurface conditions between boring locations. This report can be used for preliminary design parameters but final design should be based on TESD's final geotechnical report. Our professional services were perfonned, our findings obtained, and our recommendations prepared in accordance with generally-accepted engineering principles and practices in Southern California as of December, 2003.
