Soils Company, Inc. has prepared this Report of Rough Grading presenting the results of our observation and testing during rough grading at the above subject site. All compaction test results are included in this report in Appendix B, Table I. The proposed single-family residence was graded in accordance with the requirements of the City of T emecula and the 1997 Uniform Building Code (UBe). A 20-scale "Site Plan," prepared by Academy Consulting Corporation, and provided to us by you, was utilized to plot the location of all field density tests conducted during the rough grading operations. A copy of the 20-scale "Site Plan" was utilized as a base map for our Density'Test Location Map, Plate 1. One Tractor Doze It All performed the grading operations.

Mr. Brian Clark May 7, 2003 Page 2 Proposed Development The proposed development calls for the placement of a single-family residence with associated barn, driveway and landscape areas. It is our understanding that the development is proposed for the construction of a wood-framed, concrete slab-on-grade, single-family residence and barn. Site Description The subject site is an irregular shaped parcel. The subject site is located along the south side of Via Norte in the city of Temecula, Riverside County, California The site is bordered on the east and west by similar residential parcels, on the north by Via Norte and on the south by a large open space (common area). The general location of the site and surrounding area is shown on our Site Location Map, Figure 1. Topographically, and prior to grading, natural gradients on the site varied from 7 to 25%. Drainage on-site is accomplished by sheet flow generally to the south toward existing natural drainage channels. Prior to grading, vegetation on the subject site consisted of a low growth of annual weeds and grasses. KEYWAY EXCAVATION AND RECOMPACTION OBSERVATIONS & TESTING Prior to rough grading, the areas to be graded were cleared of vegetation, which was removed from the subject site. Rough grading operations consisted of the excavation of a keyway along the toes of the fill slopes and driveway slope. The keyways were founded a minimum of 3-ft. below the existing ground surface and a minimum of2-ft. into dense sedimentary bedrock units. The keyways were tilted at a minimum inclination of 2% into the existing hillside. The exposed earth materials within the keyways were scarified a minimum of 12-inches below the exposed surface, moisture conditioned to near optimum moisture, and recompacted to 90% of the dry density, as determined by ASTM 1557. Benching was maintained into medium dense to dense sedimentary bedrock that was free of pores & fme roots during grading operations. All topsoil/colluvial soils were removed during benching operations and were utilized as fill materials. The materials used for fill consisted of on-site light brown silty sands (Unified Soil Classification-SM) derived from the on-site topsoil/colluvial and sedimentary bedrock and import materials. Fill placement and compaction was achieved utilizing a J.D. 850C bulldozer at the proposed building pad and associated driveway areas. Moisture conditioning was accomplished utilizing a water truck. The fill was placed in 6 to 8-inch thick lifts and moisture conditioned with a water truck, as needed, to bring the material to near optimum moisture content, and was then properly compacted by track-walking with the dozer. A minimum degree of compaction of 90% was required, as determined by ASTM 1557. T.H.E. Soils Co., Inc. W.O. 565301.22 Z- o o ~.~ ~~~ 1 .~.

Areas failing to meet the minimum compaction requirements were reworked and retested until the specified degree of compaction was achieved, The elevations and the results of the field density tests are presented in Appendix B, Results of Compaction Tests, Table I. The approximate locations of the tests are shown on the Density Test Location Map, Plate 1. ~Maximum Density Determinations 'Maximum Density/Optimum Moisture determinations were performed in the laboratory on 'representative samples of the on-site soils used in the fill operations, The tests were performed in 'accordance with ASTM 01557, Test Method A The test results, which were utilized in' , determining the degree of compaction achieved during fill placement, are presented in Appendix A, ITable I. I Expansion Index Testing Expansion index testing was performed on a representative sample of the upper 3-ft of earth materials exposed at the pad surfaces. Test results yielded an expansion index of 25, which iridicates that the on-site soils exhibit low expansion potential (21-50). Test results are presented in ,Appendix A, Table 11, 'Silluble Sulfate Content ,A. representative sample of the upper 3-ft, of the earth materials exposed on the pad surface was , obtained for testing, It is anticipated that, from a corrosivity standpoint, Type II Portland , Cement can be used for construction, Test results performed on the representative sample of the . upper 3-ft, of earth materials exposed on the pad surface, at the completion of grading, indicated 26 ppm of soluble sulfate, which equates to a negligible sulfate attack hazard (Table 19-A-4, 1997 .

Therefore, the entire house and garage building pads were overexcavated a minimum of 3-ft below the finish grade elevation and to limits of the building pad, as represented by the contractor, If the building pad elevation or location is altered or relocated, T.H.E. Soils Co" Inc. should review the proposed location and additional recommendations will be made at that time. RECOMMENDATIONS Foundation Desigu It is anticipated that the foundation elements should be founded entirely in compacted fill materials. T,H,E. Soils Company, Inc, should perform a footing inspection, prior to placement of reinforcement, to insure the proposed footing excavations are in conformance with the job specifications. See inclusion in Appendix A, which references WAC Geotechnical Inc.'s, "Subsurface Soils Engineering and Engineering Geologic Investigation for Proposed GradinglResidential Building Construction and Foundation Evaluation for Property Known as Lot 198, Tract 3883, City of Temecula, Riverside County, California; A.P.N.s 919-092-007," Dated September 12,2002. Concrete slabs, in moisture sensitive areas, should be underlain with a vapor barrier consisting of a minimum of six~mil polyvinyl chloride membrane with all laps sealed. A 2-inch layer of clean sand should be placed above the moisture barrier. The 2-inches of clean sand is recommended to protect the visqueen moisture barrier and aid in the curing of the concrete. Footings should be set back from the top of all cut or fill slopes a horizontal distance equal to at lea~t Y:z the vertical slope height with a minimum setback of at least 5-ft, Total settlements under static loads of footings supported on in-place bedrock materials and sized for the allowable bearing pressures are not expected to exceed about 1/2 to 3/4 of I inch, Differential settlements under dynamic loads of footings supported on properly compacted fill materials and sized for the allowable bearing pressures are not expected to exceed 1!4-inches for T.H.E. Soils Co., Inc, W.O. 565301.22 ~ . . Mr. Brian Clark May 7, 2003 Page 5 a span of 40-ft. These settlements are expected to occur primarily during construction, Soil engineering parameters for imported soil may vary, Surface Drainage Surface drainage should be directed away from foundations of buildings or appurtenant structures. All drainage should be directed toward streets or approved permanent drainage devices, Where landscaping and planters are proposed adjacent to foundations, subsurface drains should be provided to prevent ponding or saturation offoundations by landscape water. €onstruction Monitoring Observation and testing, by T.H.E, Soils Company, Inc. is essential to verifY compliance with recommendations and to confmn that the geotechnical conditions encountered are consistent with the recommendations of this report, T.H.E.

Tract No. 3883 W,O,0059Q ~.J Resistance to Lateral Loads Resistance III lateral loads can be restrained by friction acting al the base of foundations and by passive earth pressure. A coefficient of friction of 0,30 Illay bc asslIllled with the nonnal dead load forces for footing established on compacted fill. An allowable passive lateral earth resistance of 247 pounds per square foot per foot of depth, may be assumed for the sides of foundations poured against compacted fill, However, the maximum lateral passive earth pressure is recommended not to exceed 1800 pounds, For design, lateral earth pressures oflocal soils when used as level backfill may be estimated from the following equivalent fluid density: Active: Passive: At Rest: ; 41 pcf 247 pcf ,,62 pcf 4.4 Shrinkage and Subsidence Based on the results of in-situ density and laboratory resting conducted for the project areas under study, it is our opinion that local site soils when used during grading, may be subjected to a volume change, Assuming a 90% relative compaction for the compacted fill, and assuming an o\uexcavation and recompaction of 36-inches of the existing surficial soils, such volume change due to shrinkage is expected to be on the order of 10 to 20 percent for colluvial soils, The above percentages are for estimation purposes, Actual percentage may vary during construction.

It is recommcnded that no surcharge loads such as construction cquipment, bc allowed within a line drawn upward at 45 degree fi'om the toe of excavation. Usc of sloping for deep excavations may be applicable where plan dimensions of Ihe excavation are not constrained by any existing structure. 4.5.2 Supported Excavations If vertical excavations exceeding 5 feet in depth become warranted. excavation should use shoring to support side walls. . 4.6 Site Preparation Site preparations should include cut subexcavations and placement of soils as engineered fill. Such earth work should be in accordance with the applicable grading recommendations provided in the current UBC and as recommended within this report, This office should be notified 72 hours in advance of importing soils to site for placement as compacted fill, It will be necessary for the project soils engineering consultant to sample import soils with subsequent laboratory testing to detemlinc suitability of import soils for project construction. It i~ strongly recommended that import soils be sinlilar to site soils. The use of clayey soils for pad construction, is not recommended. 4.7 Soil Caving During excavations for decp utility trcnches, '~ome' caving may be expectcd. .All tcmporary excavations should be made at a 2: 1 (horizontal to vertical) slope ratio or flatler. and/or as per the construction guidelines provided by CaIOSH1\. 4.8 Retaining Wall Rctaining Slrllt'lures. if planned, should be dcsigllcd using the ti1110wing equivalent fluid densit)': r- Slope Surface of l:quivalenl Fluiu Densit:, (.[lef) Retained Material Importcd Local (horz. to vcrt.)
