AND FINE GRADING Residential Pad, Lot 8, Tract 9833, A.P.N 950-040-007 Jedediah smith Road Temecula, California .Gentlemen: INTRODUCTION IThis report presents the results of our observation and testing :performed during construction and grading for the residential :pad, and access driveway during rough and fine grading of the !subject lot. 'The pad was constructed on the south side of Jedediah smith Road Ian improved paved road in the city of Temecula. The results of our Field Density Tests obtained during grading are tabulated in :Table I, Results of Compaction Tests. The approximate locations of the tests are shown on the Plot Plan, Plate 1. The 3D-scale ,Rough Grading Plans were prepared by Inland Valley Development .Consultants, Wildomar, undated, and were used to plot our data land guide the grading, along with field staking. 'Pro;ect DescriDtion .The proposed development consisted of constructing a residental :pad, and long access driveway with a culvert and wet crossing. In ,general, the pad required cuts up to 12 feet on the south and 'fills to 8 feet on the north-northwest. Cut and fill slopes were 'constructed at finished inclinations of 2:1 (horizontal to ,vertical) or flatter. The pad was graded in transition from cut to fill, so overexcavation was required. The cut slopes consist of dense hard sedimentary bedrock or massive colluvium that had no adversely oriented bedding to develop stability problems, and ,are stable as constructed. The fill slopes are stable as .constructed, based on high strength values. o .

PECHANGUA 1968 (PR1988) 1..- 98133-01 Ipage 3 IPurDose of Gradinq The purpose of the grading was to prepare the site for the .proposed construction of the one and two-story single family 'residence, and driveway access. GRADING PROCEDURES ;Gradinq Procedures :The site was stripped of the heavy grasses in the areas to receive fill and the pad area, and removed to non-structural 'areas of the lot. The areas to receive fill were then 'overexcavated 3 1/2 - 7 feet or until the dense underlying 'sedimentary bedrock was encountered. A fill key was installed as !shown on Plate 1. The fill materials were brought to near optimum .moisture utilizing a 1.5 inch fire hose when necessary, and :compacted with a large Caterpillar D8K bulldozer. IThe grading contractor was Jim Conner, Temecula. TESTING !Field Densitv Testinq Field density testing was performed in accordance with ASTM :D1556-64 (Sand Cone Method). The elevations and the results of .the field density tests are presented in Table I of this report. iThe approximate location of the tests are shown on the Grading :Plan, Plate 1. 'Maximum Densitv Determinations 'Maximum density/optimum moisture determinations were made from .representative samples of on-site soils used in the fill :operations. The tests were performed in accordance with ASTM D ,1557 which consist of compacting 5 equal layers of soil in a 1/30 cubic foot volume mold with 25 blows of a 10 pound hammer falling .18 inches. The results of the Maximum density/optimum :determination are presented herein as Table II, Laboratory Test :Resul ts . ~ , 98133-01 Page 4 iExDansion Testinq ,A finished grade sample was obtained and tested for expansion !utilizing the U.B.C. 29-2 method. The test yielded an expansion .index (E.I.) of 38 which is considered moderately expansive. The : foundation .should be designed in accordance with the attached '''Foundation and Slab Recommendations" parameters for medium ,expansion soils (Plate 2). SUMMARY .Our description of grading and backfill operations, as well as .observations and testing services, were limited to those grading :operations performed between March 27 and April 20, 1998. The :conclusions and recommendations contained herein have been based .upon our observation and testing as noted. It is our opinion, Ithat the work preformed in the areas denoted has generally been 'accomplished in accordance with U.B.C., as amended by Ordinance No. 457 specifications, and the requirements of the regulating :agencies and is accetable for its intended purpose. No conclusions or warranties are made for areas not tested or : observed. This report should be considered subject to review by Ithe controlling authorities. This opportunity to be of service is sincerely appreciated. If :you have any questions, please call. t\ :98133-01 ipage 5 2-28-00 ;Larry J.
