T1060-C February 1999 Page 2 Vallejo Avenue and Interstate 15 on the east and west, respectively, and existing church structures and graded pads on the south and north, respectively. 1.2 PROJECT DESCRIPTION It is understood that the subject site is to be developed with an amphitheater, classroom structure and ball field area. Prior to grading operations, topography and surface conditions of the site were relatively flat to moderately sloping at a gradient of less than 10 percent. A natural stream bed bisects the site, extending from Vallejo Avenue to the Interstate 15 Freeway. 2.0 SCOPE OF WORK 2.1 TIME OF GRADING This report represents geotechnical observations and testing during the construction operations from July 7,1998 through December 30,1998. 3.0 CONTRACTOR AND EQUIPMENT The grading operations were performed by Clayton Engineering, Inc. through the use of several Cat 623 scrapers, one (1) blade, one (1) 824 C rubber tire dozer and one (1) water truck. 3.1 GRADING OPERATIONS Grading within the subject site consisted of a cut/fill and import fill placement operation. Grasses and weeds were removed prior to fill placement. Fill material was generated from the southeastern portions of the site, and used to bring the southwestern portions of the site to finish grade elevation. Import material was used to bring the central and western portions of the site to finish grade elevation. Removal of alluvium, slopewash, etc., was performed in the western portion of the site to depths ranging from 1 to 7 feet below original elevation. Over-excavated earth material was stockpiled and later used as fill. Fill slopes were constructed along the natural water course that bisects the site, resulting in a well defined drainage channel. Bottoms were observed, probed and found to be into competent native material by a representative of this firm. Keying and benching into competent bedrock was observed during the grading operations. The exposed bottoms were scarified and moisture conditioned to a depth of 12 inches then compacted to 90 percent. Fill was placed in lens thicknesses of 4 to 6 inches, thoroughly moisture conditioned to near optimum moisture content, then compacted to a minimum of 90 percent relative compaction. Moisture EnGEN Corporation .3> I I I I I I I I I I I I I I I I I I I Rancho Community Church Project Number: T1060-C February 1999 Page 3 conditioning of the on-site soils was performed during the compaction process, through the use of a water truck. The pad area was 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. 3.2 CUT/FILL TRANSITION Over-excavation was not performed on the cut portion of the graded pads. Therefore, cut/fill transitions exist on the subject site. It is recommended that overexcavation be performed in the cut portion of cut/fill footprint areas once proposed structure locations are determined. Over-excavation should be performed in accordance with the recommendations given in the Referenced No. 2 report. 4.0 TESTING 4.1 FIELD TESTING PROCEDURES Field in-place density and moisture content testing were performed in general accordance with ASTM-D-2922-81 (90) and ASTM-D-3017-88 procedures for determining in-place density and moisture content, respectively, ,-!sing nuclear gauge equipment. Relative compaction test results were within the 90 percent required for all material placed and compacted. Test results are presented in the Appendix of this report. FiiI depths and test locations were determined from review of the referenced grading plans. 4.1.1 LASORA TORY 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. 4.1.2 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 D1557-91 procedures. The test results are presented in the Appendix (Summary of Optimum Moisture Content / Maximum Dry Density Relationship Test Results). 4.2 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 procedure utilized was the Uniforrn Building Code Test Designation 18-2. The material tested consisted of silty EnGEN Corporation 4 I I I I I I I I I I I I I I I I I 1 I Rancho Community Church Project Number: T1060-C February 1999 Page 4 sand, to sandy silt, which has an Expansion Index of O. This soil is classified as having a very low expansion potential. The results are presented in the Summary of Expansion Index Results in the Appendix of this report. 5.0 EARTH MATERIALS The natural earth materials encountered on-site, generally consisted of brown to tan, silty sand to sandy 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 recornmendations provided by the Referenced No.2 Geotechnical/Geological Engineering Study. 6.1 GENERAL Based on the observations and tests performed during grading, the subject site in the areas noted has been completed in accordance with the Referenced No.2 Geotechnical/Geological Engineering Study 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 intended use. 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 presaturation, or other earth work completed for the development of 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.
