Fill material was generated from the cut portions of the site, and used to bring the fill portions of the pad and driveway areas to finish grade elevation. Removal of alluvium, slopewash. etc,. was performed to a depth of 2 to 4-feet below original elevation, Overexcavated earth material was stockpiled and later used as fill, Bottoms were observed, probed and found to be into competent Pauba Formation by a representative of this firm. Keying and benching into competent Pauba Formation bedrock was observed during the grading operations, Overexcavation was performed in the cut and shallow portions of the proposed structural footprints to a depth of 3-feet below finish grade elevation and to a minimum distance of 5-feet outside the proposed structure. The exposed bottoms were A..

Fill was placed in lens thicknesses of 6 to 8-inches. thoroughly moisture conditioned to near optimum moisture content. then compacted to a minimum of 90 percent relative compaction. Moisture conditioning of the on-site soils was performed during the compaction process through the use of a water truck, The pad areas were generally graded to the elevations noted on the Grading Plan, However, the actual pad location. dimensions. elevations. slope locations and inclinations, etc, were surveyed and staked by others and should be verified by the Project Civil Engineer. 2.4 RETAINING WALL BACKFILL Density testing of retaining wall backfill to date is included in this report, However. some retaining wall backfill along the driveway still remains to be done, All retaining wall backfill affecting the building pads has been completed and is reported herewith. A final report will be prepared at the completion of the remainder of the retaining wall backfill. 3.0 SLOPE STABILITY 3.1 FILL SLOPES The small cut slope at the top of the driveway entry to lot 2 was constructed as planned at the slope ratio of 1: 1 , All other design fill slopes were constructed in substantial accordance with the plans at a slope ratio of approximately 2:1 (horizontal to vertical). It is our opinion that the fill slopes as constructed possess gross and surficial stability in excess of generally accepted minimum engineering criteria (Factor of Safety at least 1,5) and are suitable for their intended purpose, provided that proper slope maintenance procedures are maintained. These procedures include but are not limited to installation and maintenance of drainage devices. and planting of slope faces to protect from erosion in accordance with the City of Temecula Grading Codes. The maximum height of fill slope covered in this report is 29-feet. 3.2 CUT SLOPES All cut slopes were constructed in substantial accordance with the plans at a slope ratio of approximately 2:1 (horizontal to vertical). The cut slopes were surficially inspected by the Project Geologist and consist of Pauba Formation bedrock. No adversely oriented joints or -s EnGEN Corporation I I I I I I I I I I I I I I I I I I I Mr, Paul Gupta Project Number: T3065-C March 2005 Page 4 planes of weakness were observed during our inspection. It is our opinion that the cut slopes as constructed possess gross and surficial stability in excess of generally accepted minimum engineering criteria (Factor of Safety at least 1,5) and are suitable for their intended purpose, The maximum height of cut slope covered in this report is 29-feet. 4.0 TESTING 4.1 FIELD TESTING PROCEDURES Field in-place density and moisture content testing were performed in general accordance with ASTM D 2922-03 and ASTM D 3017-01 procedures for determining in-place density and moisture content. respectively. using nuclear gauge equipment. Relative compaction test results were within the 90 percent required for all material tested, which is an indication that the remainder of the fill placed has been properly compacted, Test results are presented in the Appendix of this report. Fill depths and test locations were determined from review of the referenced grading plans. 4.2 LABORATORY TESTING The following laboratory tests were performed as part of our services during the grading of the subject site, The test results are presented in the Appendix of this report, 4.2.1 MOISTURE-DENSITY RELATIONSHIP TEST Maximum dry density-optimum moisture content relationship tests were conducted on samples of the materials used as fill. The tests were performed in general accordance with ASTM D 1557-02 procedures, 4.2.2 EXPANSION INDEX TEST A soil sample was obtained for expansion potential testing from the building pad area upon completion of rough grading of the subject site, The expansion test was performed in accordance with UBC 18-2. The material tested consisted of light-brown silty sand. which has an Expansion Index of 0, This soil is classified as having a very low expansion potential. 4.2.3 SOLUBLE SULFATE TEST Based on this firm's familiarity with the soils used to construct the building pad. it is our opinion that soluble sulfates are not a concern. and as a result, normal Type II cement can be used in concrete making contact with the native soils. ~ EnGEN Corporation I I I I I I I I I I I I I I I I I I I I Mr. Paul Gupta Project Number: T3065-C March 2005 Page 5 5.0 EARTH MATERIALS The natural earth materials encountered on-site generally consisted of light-brown to dark- brown sand. with varying percentages of silt. 6.0 CONCLUSIONS AND RECOMMENDATIONS No conditions were encountered which would cause a change in the previously provided design and construction recommendations. As a result, design and construction should adhere to the recommendations provided in the Referenced NO.1 "Feasibility Geotechnical Study", 6.1 GENERAL Based on the observations and tests performed during grading, the subject site, in the areas noted as test locations. has been completed in accordance with the Referenced No. 1 report. or as amended in the field based on conditions encountered, the project plans and the Grading Code of the City of Temecula, The graded site. in the areas noted as graded. is determined to be adequate for the support of a typical residential development. Any subsequent grading for development of the subject property should be performed under engineering observation and testing performed by EnGEN Corporation. Subsequent grading includes, but is not limited to, any additional fill placement and excavation of temporary and permanent cut and fill slopes. In addition, EnGEN Corporation should observe all foundation excavations, Observations should be made prior to installation of concrete forms and/or reinforcing steel so as to verify and/or modify. if necessary. the conclusions and recommendations in this report Observations of overexcavation cuts, fill placement. finish grading, utility or other trench backfill. pavement subgrade and base course, retaining wall backfill. slab pre-saturation. or other earthwork completed for the development of the subject site should be performed by EnGEN Corporation, If any of the observations and testing to verify site geotechnical conditions are not performed by EnGEN Corporation. liability for the safety and performance of the development is limited to the actual portions of the project observed and/or tested by EnGEN Corporation. 7.0 CLOSURE This report has been prepared for use by the parties or project named or described above.
