Compaction test results are included in this report in Appendix C, Table 1. The subject pads were graded in accordance with the requirements of the City of Temecula and the 2001 California Building Code (CBC). The 40 -scale "Site Plan" prepared by MDMG, Inc., of Temecula, California, was utilized during grading to locate our field density tests. A reduced copy of the plan was utilized as a base map for our test locations presented as Plate 1. Lewis Valley Contractors performed the grading operations.

Soils Co. Inc. W.O. 1197701.22 0 Mr. Chuck Delgado August 31, 2007 Page 2 Proposed Development 0 The proposed development calls for the construction of two single-family residences. Based on our observation and the site plan, it is anticipated that the subject structures will be founded entirely in properly compacted engineered fill material and that conventional footings and typical slab -on - grade construction will be utilized. Site Description The subject site is located in the city of Temecula in Riverside County, California. The site is bordered on the east by Ormsby Road, on the south by Santiago Road, and on the west and north by large parcel single-family residential developments. The location of the site and surrounding area are shown on our Site Location Map, Figure 1. Prior to grading, the site consisted of moderately sloping terrain, which, for the most part, was vacant and undeveloped. Vegetation on the subject site consisted of a sparse growth of annual weeds and grasses, and overall relief at the site for the proposed development was approximately 60+ -ft. GRADING PROCEDURES Site Preparation The subject pads were cleared of weeds and debris prior to commencement of grading, which were disposed of offsite. The pads were overexcavated a minimum of 3.0 feet below pad grade and extended approximately 5 -ft outside the building footprint. The contractor staked the limits of the pad prior to overexcavation and recompaction. A keyway for parcel l was established for the approximately 5 -foot high fill slope along the southern portion of the proposed house pad. The keyway was established a minimum of 2 -feet into medium dense native materials at the toe and tilted a minimum of 2% into the hillside. The earth materials exposed at the keyway bottom were free of pinpoint pores and roots. A second keyway for parcel 2 was established for the approximately 6 -foot high fill slope along the southern portion of the proposed house pad. The keyway was established a minimum of 2 -feet into medium dense native materials at the toe and tilted a minimum of 2% into the hillside. The earth materials exposed at the keyway bottom were free of pinpoint pores and roots. Prior to placement of fill within the removal, the bottoms were scarified a minimum of 12 -inches, brought to near optimum moisture content, and compacted to at least 90% relative compaction as determined by ASTM D-1557 test method. The fill materials were leveled and mixed by a D4 T.H.E. Soils Co. Inc. W.O. 1197701.22 1] Mr. Chuck Delgado August 31, 2007 Page 3 0 dozer, a 623 scraper, a Cat blade and a loader, and compaction was achieved by wheel rolling by the water truck and loader and track walking by the dozers, and incidental contact from the loaded and unloaded scrapper. TESTING PROCEDURES Maximum Density Determinations Maximum Density/Optimum Moisture determinations were performed in the laboratory on representative samples of onsite soils used in the fill operations. The tests were performed in accordance with ASTM 131557, Test Method A. Test results, which were utilized in determining the degree of compaction achieved during fill placement, are presented in Appendix B, Table I. Fill Soils Soils utilized for compacted fill typically consisted of medium brown silty Sand (Unified Soils Classification -SM) derived from onsite colluvial/alluvial soils and sedimentary bedrock units. Compaction test results are presented in Appendix C, Results of Compaction Tests, Table I. Cut/Fill Transitions Rough grading operations at the site included overexcavation of the two house pads to a minimum of 5 -ft outside the building footprint to a minimum of 3 -ft below finish grade elevation as staked by the contractor, therefore, eliminating the cut/fill transition. Fill and Cut Slove Construction Fill slopes were constructed at a 2:1 (horizontal:vertical) slope ratio running along the southern portion of the proposed house pad on Parcel 1 at a maximum height of 5 -ft. and on Parcel 2 at a maximum height of 6-11. The fill slopes were constructed from existing colluvial/alluvial soils and sedmentary bedrock units. Cut slopes were constructed at a 2:1 (horizontal:vertical) slope ratio on the northerly portion of each pad at maximum heights of l I and 15 -ft. Field Density Testing Field density testing was performed in accordance with ASTM Test Method D2922-01 (nuclear gauge). 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 C, Results of Compaction Tests, Table 1. The approximate locations of the tests are shown on the Density Test Location Map, Plate 1. T.H.E. Soils Co. Inc.

The results, which are listed in Appendix B, Table II indicate that the expansion potential for the onsite soils varied between 13 and 19, which corresponds to a VERY LOW (0-20, Table 18-1-B, 2001 CBC) expansion potential. Sulfate & Chloride Content Soluble Sulfate Content testing was performed on a representative near surface soil sample exposed at each pad surface. The test results varied between a 0.001 to 0.033 (% by weight) amount of soluble sulfate, which equates to a negligible attack hazard (0.0 to 0.10 percentage by weight, Table 19-A-4, 2001 CBC). It is anticipated that, from a corrosivity standpoint, Type 11 Portland Cement can be used for construction. Prime Testing Laboratory, Inc. of Murrieta, California performed the laboratory testing and test results are presented in Appendix B, Table I11. Additionally, the representative samples of the near surface soils were also tested for chloride content. Chloride test results varied between 60 to 90 ppm (parts -per -million). T.H.E. Soils Company, Inc. does not practice corrosion engineering. If specific information or evaluation relating to the corrosivity of the onsite or any import soil is required, we recommend that a competent corrosion engineer be retained to interpret or provide additional corrosion analysis and mitigation. Prime Testing Laboratory, Inc. of Murrieta, California performed the testing; all test results are presented in Appendix B, Table IV. Foundation System Design It is anticipated that the foundation elements should be founded entirely in properly compacted 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. The structural engineer should design all footings and concrete slabs in accordance with the allowable foundation pressures and lateral bearing pressures presented for Class 4 soils on Table 18-1-A of the 2001 California Building Code (CBC). The allowable foundation and lateral pressures shall not exceed the values set forth in Table 18-1-A for Class 4 soils unless data to substantiate the use of higher values are submitted. Where the site is prepared as recommended, the proposed structures may bear on continuous and isolated footings. The footings should have a minimum width of 12 -inches, and be placed at least T.H.E. Soils Co. Inc. W.O. 1197701.22 0 Mr. Chuck Delgado August 31, 2007 Page 5 0 12 -inches below the lowest final adjacent grade for one-story houses, with a minimum width of 12 - inches, and be placed at least 18 -inches below the lowest final adjacent grade for two-story houses. Footings may be designed for a maximum safe soil bearing pressure for Class 4 soils as per Table 18-1-A of the 2001 CBC for dead plus live loads. 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 six mil polyvinyl chloride moisture barrier and aid in the curing of the concrete. 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 1 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 a span of 40-fi. These settlements are expected to occur primarily during construction. Soil engineering parameters for imported soil may vary. Utility Trench Backfill Utility trench backfill should be compacted to a minimum of 90% of the maximum dry density, as determined by the ASTM 1557 test method. It is our opinion, that utility trench backfill consisting of onsite or approved sandy soils can best be placed by mechanical compaction to a minimum of 90% of the maximum dry density. All trench excavations should be conducted in accordance with Cal -OSHA standards, as a minimum. The soils encountered during rough grading are generally classified as Type "C" soil in accordance with the CAL/OSHA (California, State of 2007) excavation standards. Unless specifically evaluated by the project engineering geologist, all temporary excavations should be performed in accordance with CAL/OSHA (California, State of, 2007) excavation standards for Type "C" soil. Based upon a soil classification of Type "C", the temporary excavations should not be inclined steeper than 1.5:1 (horizontal: vertical) for a maximum depth of 20 -ft. For temporary excavations deeper than 20 -ft or for conditions that differ from those described for Type "C" in the CAL/OSHA excavation standards, the project geotechnical engineer should be contacted. 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 of foundations by landscape water. T.H.E. Soils Co. Inc.
