The referenced site was graded to the efevations as shown on the Reference No. 1 plan. 2.0 SITE DESCRIPTION 2.1. Location: The site encompasses approximately 65 acres and is located west of Diaz Road and north of Avenida De Ventas, in the City of Temecula, Riverside County, Califomia. 2.2 Leqal Description: Parcels 1 through 10 of Parcel Map 24085, County of Riverside (APN 909- 120-022). 2.3 Topoaraahv: The topography of the site before grading was relatively flat on the eastem portion of the property and gently to moderately sloping on the west side of the property. A portion of the west side of the property had been previously graded flat and some fill had been stockpiled immediately south of the graded pad. Drainage on the property was toward the northeast. 2.4 Veaetation: Before grading, vegetation across the site was light to moderate and consisted of seasonal grasses, weeds, and bushes. 2.5 Structures: Before grading, there were no existing buildings or other types of structures known to exist on the site. Heavy construc6on equipment was stored on the previously graded pad at the west portian of the property. 3.0 SCOPE OF WORK 3.1 Time of Gradinca: Grading operations were conducted from August 29, 1996 through November 11, 1996. I, ~ 3.2 Eauiament: The grading opera6ons for the lots on Parcels 1 through 10 and the associated streets were performed by American Contracting, Inc. through the use of 10 Terex and Caterpillar ~ EnGEN Corporation S` i ' ~ 3.3 Westside City I Associates, LLC Projed No. T1075-C November 96 Page 3 scrapers, three (3) Caterpillar Trackmounted dozer, two (2) Caterpillar rubber fire dozers, one (1) motorgrader and several water trucks. Gradina Oaerations 3.3.1 Parcel 1: Grading consisted of an overexcavation and replacement operation. Removal of previously existing fill and overexcavation of undisturbed native material (alluvium) was performed to depths determined, by a representative of EnGEN Corporation, in the field. The depth of removals ranged from 2.0 to 8.0 feet below original grade. To ensure a minimum of 10 feet of compacted fill below finish grade elevation, removal of alluvial material was performed to a minimum depth of 4.0 feet below native grade, in the building pad area, and to a distance of 5.0 feet outside proposed perimeter footings. Bottoms, once approved, were moisture conditioned to within 2.0 percent of optimum, processed, and compacted to a minimum of 90 percent relative compaction. Fills, approximately 8.0 feet to 15.0 feet, were placed and compacted to a minimum of 90 percent relative compaction. 3.3.2 Parcels 2 throuah 7: Grading consisted of a cut and fill operation. Excavations were made in the westem portion of each parcel to achieve proposed pad elevations. The materials obtained from the excavation were used to bring Parcels 1, 8, 9,10, the northem portion of Parcel 5, eastem portions of Parcels 2, 3, 6 and 7, Diaz Road between stations 114+50 through 123+00 and Remington Street between stations 10+50 through 17+50 and 26+50 through 39+00. Removal of existing undocumented fill material, slopewash, etc. was pehormed in the areas to receive compacted fill on each parcel prior to placing new fills. The depth of removals on each parcel ranged from approximately 1.0 to 5.0 feet as determined by a representative of EnGEN Corporation. Keys were excavated at the toe of the fill slopes on each parcel as shown on the Rough Grading Report Site Plan presented in Appendix III. The keys were excavated a minimum of 2.0 feet into firm, ~ EnGEN Corporetion Westside City I Associates, LLC Project No. T1075-C November96 Page 4 3.3.3 weathered and/or unweathered bedrock material and were a minimum of 15 feet in width. The limits of the overexcava6on, keys, fill placement, etc. are shown on the Rough Grading Report Site Plan. The overexcavated material was stockpiled and later used as fiil. The overexcavation bottoms were observed, probed, and approved as being in firm, competent materiai suitable for support of fill materials and proposed structure(s). Subgrade materials within the overexcava6on areas were scarified to a minimum depth of 12 inches below the exposed surface and recompacted to a minimum of 90 percent relative compaction. Fill material was placed in lens thicknesses of 6.0 to 8.0 inches and compacted to a minimum of 90 percent relative compaction. Moisture conditioning of the on-site soifs was performed during the compaction process due to the in-situ moisture content of the soils being below optimum moisture content. Benching into firm undisturbed native material was observed during placement of fiil. No import soils were used as fill during the rough grading operations. The parcels were generally graded to the elevations noted on the grading plan. However, the actual pad locations, dimensions, elevations, slope loca6ons and inclinations, etc. were determined by others and should be verified by the project Civil Engineer. Parcels 8. 9 and 10: Grading consisted of an overexcavation and replacement operation. Removal of previously existing fill and overexcavation of undisturbed native material (alluvium) was performed to depths determined, by a representative of EnGEN Corporation, in the field. The depth of removals ranged from 2.0 to 4.0 feet below original grade. Bottoms, once approved, were moisture conditioned to within 2.0 percent of optimum moisture, processed, and compacted to a minimum of 90 percent relative compaction. Fill material was generated from the westem cut portion of the project site to bring the subject parcels to finish grade elevation. Filis, approximately 7.0 to 9.0 feet, were placed and compacted to a minimum of 90 percent relative compaction. Fills were piaced and compacted using the same methods described in Section 3.3.2 of this report. ~ EnGEN Corporation Westside City I Associates, LLC Project No. T107SC November96 Page 5 3.4 CuUFill Transition: Overexcavation was not performed on the cut portion of Parcels 2, 3, 4, 5, 6 and 7. Therefore, cuUfill transitions exist on the subject parcels. It is recommended that overexcavation be performed in the cut portion of the parcels once proposed structure locations are determined. Overexcavation should be performed in accordance with the recommendations given in the Reference No. 6 report. 4.0 TESTING 4.1 Field Testinq: Field observafions and in-place density testing were performed on a full-time and part-time as-needed basis during the grading operations. Where tests indicate failing results, the soils were reprocessed until at least 90 percent relative compaction was achieved in the fill areas. Test Iocations were randomly selected in the areas receiving fill and were recorded using approximate locations and elevations as could be determined in the field. Field in-place density and moisture content testing were performed during the placement of the fill materials during the rough grading operations in general accordance with the following ASTM test procedures: Test Method for Density of Soil and Soil-Aggregate in Place by Nuclear Methods (Shallow Depths) - ASTM D2922-81(1990). Test Method for Water Content of Soil and Rock in Place by Nuclear Methods (Shallow Depth) - ASTM D3017-88. The test results indicate that soils were compacted to a minimum of 90 percent relative compaction.. Test results are presented in Exhibit I in Appendix I. The locations of the in-place density tests are presented on the Rough Grading Report Site Plan in the Appendix. 4.2 Laboratorv Testina: The following laboratory tests were performed as part of our services during the rough grading of the subject site. The test results are presented in the Appendix. 4.2.1 Moisture-Densitv Relationship Test: Maximum dry density - optimum moisture content ~ EnGEN Corpo2tion Westside City i Associates, LLC Projed No. T1075-C November 96 Page 6 4.2.2 5.0 5.1 5.2 rela6onship tests were conducted on samples of the materials used as fill. The tests were performed in generai accordance with ASTM D1557-91 procedures. The test results are presented in the Summary of Optimum Moisture Content / Maximum Dry Density Relationship Test Results. Expansion Index Testina: Soil samples were obtained for expansion potential testing upon completion of rough grading of the subject parcels. The expansion test procedure utilized was the Uniform Building Code Test Designation Standard 29-2. The material tested consisted of silty fine sand with minor amounts of clay, which had an Expansion Indexes of 22 and 50, corresponding to a low expansion potential in accordance with Table 29-C of the Uniform Building Code. The results are presented in the Summary of Expansion Index Results in the Appendix. As a result, construction recommendations for expansive soil purposes should be addressed on a Lot by Lot basis, so that it can be specifically tailored for each proposed structure. No special construction is required for the structure on Parcel 1 since the specified details for tilt-up construction exceed the design needs for expansive soils purposes. EARTH MATERIALS 1 AS GRADED GEOLOGIC CONDITIONS Filt Areas: The material used as fill was generated from cut areas on site and was observed to consist mainly of silty sands and sandy silts with some clay and intermittent gravels and some cobbles. Native Cut Areas: Geologic conditions encountered in native cut areas appeared to be similar to those described in the referenced geotechnical investigations. Pauba Forma6on bedrock consisting of sandstones, siltstones, sandstone - siltsone mixtures, along with scattered lenses of gravei and cobble are exposed in native cut pad and native cut slope areas on the site. Structurally, native cut areas are comprised of massive cuflfili channel deposits with occasional cross bedding and some q EnGEN Corporation Westside City 1 Associates, LLC Project No. T1075-C November 96 Page 7 6.0 6.1 signs of slightly dipping strata to the north-northeast. The cut slopes were evaluated during grading by an EnGEN Corporation Certified Engineering Geologist. Adverse geologic conditions that might affect gross siope stability were not encountered. Local areas that might affect su~ciai slope stability (erosion) were noted. It is recommended that a slope maintenance program (siope protecting vegetation) be implemented as soon as possible to prevent erosion of slope faces. In addition, the lower portion of the fiil over cut slope west of Lot 6 and a porlion of Lot 3 was observed to be saturated with groundwater. Therefore, a 4-inch diameter subdrain was installed at the toe of this slope (see plans) in order to exit excess amounts of water off the pad and slope areas. CONCLUSIONS AND RECOMMENDATIONS General: Based on the obseroations and tests performed during grading, the subject site in the areas noted has been completed in accordance with the project plans and specifications, the Grading Code of the City of Temecula. The graded site in the areas noted as rough graded is determined to be adequate for the support of a typical commercial structure and appurtenant facilities. 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, overexcava6on of the cut portion of the transition area, and 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 earthwork completed for the development of subject site should be ~p EnGEN Corporadon Westside City 1 Aasociates, LLC Projed No. T1075-C November 96 Page 8 6.2 7.0 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 actuai portions of the project observed and/or tested by EnGEN Corporation Erosion Control Measures: The graded pads are large and will generate significant runoff during rainy weather. Special precaution needs to be taken at the point of runoff discharge to prevent serious erosion at such points of runoff concentration. Care should be taken to protect ea~then berms along the tops of slopes near the discharge area so that these berms do not erode to such a degree that the drainage spilis onto the slope face.
