The report represents a summary of the observations and compaction testing of the fill placed on the slope repair. Field testing and observations indicate the compaction and grading of the soil was performed properly. The soil should perform satisfactorily for the expected usage. The included findiljlgs and recommendations have been derived in accordance with generally accepted professional principles and practices in the fields of soil mechanics and foundation engineering. This warranty is in lieu of all other warranties, either expressed or implied. The opportunity to be of continued services is sincerely appreciated. If you should have any questions or require further information, please contact me at your convenience. 7,-. INTRODUCTION In accordance with your request, tests have been performed on the fill placed on the slope repair. The excavation, fill placement, compaction and testing associated with this phase of the grading was performed in September, 1999. This report presents a summary of the testing services provided. PROJECT DESCRIPTION The existing site has a single family residence with attached garage constructed on it with associated landscaping and access drive. The fill slope was prepared for erosion control and recompacted. GRADING PROCEDURES The observations and test results indicated that the grading was performed in the method consistent with the U.B.C, as amended by Ordinance 457. All areas to receive fill were stripped and c1eaEed of vegetation and soft soil prior to placement of soil fill. Keying and benching into natural ground was completed in general compliance with the Uniform Building Code, Appendix Chapter 33. The minimum acceptable degree of compaction was 90 percent of the maximum density. FIELD DENSITY TESTING Field density testing was performed in accordance with ASTM D1556-64 (Sand Cone Method). The results of the field density tests are presented in Table I of this report. The approximate location of the tests are shown on the Plot Plan, Plate 1. MAAIMUM DENSITY 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 D1557- 78 Method. '7 , , LIMITATIONS The findings and recommendations of this report were prepared in accordance with contemporary prindples and practices in the field of geotechnical engineering. No other warranty or guarantee is either expressed or implied. Only a portion of the subsurface soils and conditions were evaluated or observed and the conclusions are based upon an interpretation of the soils conditions encountered in the field tests. Conclusions are also based on the assumption that these findings do not vary appredably in the adjacent areas. However, minor variations may occur: should soil conditions significantly different be encountered in the future, an assessment of the impact on subsequent recommendations should be made. All future grading and fill placement should be performed under the inspection and testing of a registered civil engineer. SUMMARY Our description of grading and backfill operations, as well as testing services, were limited to those grading operations performed in September, 1999. The conclusions and recommendations contained herein have been based upon our observation and testing as noted. To the best of my knowledge, the work within my area of responsibility is in accordance with applicable provisions of U.B.C. as amended'by Ordinance 457. ~ - GUNVANT THAKKAR, PROFESSIONAL ENGINEER 45712 Classic Way, Temecula, California 92592 (909) 676-7541 Mr. Doyle Maximum Density Optimum Moisture Content (pcf) (%) 129.5 10.5 Eleva- Tion (Feet) Max.
