P.O. Box 14430 Palm Desert, California 92255 Project: Parcel Map 30420 The Centre at La Quinta La Quinta, California Attention: Mr. Bob Neubauer Subject: Report of Testing and Observations Performed During Rough Grading File No.: 8628-02 02-11-715 Reference: Earth Systems Southwest, Geotechnical Engineering Report, dated April 30 2002, Report No.: 02-11-715. Submitted herewith is a report of testing and intermittent observations performed during the grading on the above referenced project. Grading operations were performed by Nuevo Engineering using conventional heavy equipment. Testing was performed as per authorization of Mr. Bob Neubauer. Test results are presented on the attached test report sheet with their estimated locations plotted on the accompanying plan. Compaction tests are performed in accordance with ASTM D 2922- 81, Method A or B, and ASTM D 3017-88 Nuclear Density Test -Procedures. Maximum Density -Optimum Moisture is determined in the laboratory in accordance with ASTM D 1557-91, Method A or C. Test results are as follows: Soil Description USCS Maximum Density Optimum Moisture Gray brown silty Sand SM 104.5 pcf 13.5% Brown silty Sand SM 105.5 pcf 14.5% November 7, 2002 DISCUSSION: -2- File No.: 08628-02 02-11-715 1. The project is located on the southwest corner of Highway 111 and La Quinta Centre Drive in the City of La Quinta. 2. Prior to grading, the site consisted of vacant land with moderate native desert brush. The northern portion of the site is relatively flat while the southern portion of the site is -hummocky, controlled by small vegetation induced sand dunes. A large sand dune is located near the southeast corner of the site with up to 25 feet of relief and very dense mesquite growth on the leeward side (east). An existing concrete slab and miscellaneous masonry walls are located on the top of a large sand dune (15 to 20 feet) in the northeast portion of the site. Scattered miscellaneous trash and debris was noted throughout the site with heavier concentrations of trash including some 55 -gallon drums near the southeast corner of the site. A temporary retention basin for storm water drainage from the development to the west, has been constructed in the southwest portion of the site, and does encroach within the proposed Wal-Mart pad. 3. The proposed development will consist of an approximately 225,000 square foot Wal- Mart Superstore, a 86,584 square foot retail store (Parcel 5), a 19,200 square foot building for miscellaneous shops, a gas station (Parcel 11) and six parcels for future development (Parcels 2 through 10). We assume that the proposed Wal-Mart store will be of concrete tilt -up or masonry block construction while the other retail buildings and shops. may be constructed of masonry or wood frame and stucco and will be supported by conventional shallow continuous or pad footings. A retention basin was also excavated to the.west of the future Wal-Mart. 4. The scope of our work was based on the referenced geotechnical engineering report, and plans by The Keith Companies. 5. The site was cleared of any pre-existing vegetation and pre -watered prior to grading operations. 6. No plans are available for the future development of Parcels 2, 3, 4, 7, 8, 9, and 10. Therefore, these areas were not over excavated and may require future grading when foundation plans and possible loading dock areas are established. 7. Parcel 1, Parcel 5, Parcel 6, and Parcel 11 were over excavated 5 feet below building pads and extended five feet beyond the outer edge of exterior footings. The bottom of the excavations was moisture conditioned, and completed an additional one -foot. 8. An additional 4 feet of over -excavation was performed in the Wal-Mart loading dock areas on the eastern west sides of the pad creating a 9 -foot over -excavation below building pad grade. 9. Structure areas that received fill were moisture conditioned and compacted in the upper 3 feet of the original grade. EARTH SYSTEMS SOUTHWEST November 7, 2002 - 3 - File No.: 08628-02 02-11-715 10. - The future block wall to be located south of Wal-Mart was also over excavated 5 feet -- below finished grade. 11. Previously, fill materials consisting of previously removed soils were placed in relatively thin lifts and compacted into place. 12. A demolished concrete irrigation standpipe was encountered in the northeast corner of Parcel 11. The area was over excavated with a track -hoe excavator to a depth of 10 feet below building pad and moisture conditioned with water. This work resulted in 5 feet of over -excavation and recompaction. 13. An irrigation line was encounter from Parcel 11 approximately 1 to 2 feet deep and ran north onto. Parcel 10 where it turned east and continued to the eastern property line to a. "T". The irrigation line.then ran south and north. The line was located and crushed with the excavator and moisture conditioned with water. The areas were then compacted with scrapers. 14. A total of 389 compaction tests were performed. 15. Test results indicate that a minimum of 90% of maximum dry density has been obtained in the areas tested. 16. . The test locations are approximate and are determined by pacing and sighting from prominent field features. In our work, we have relied on topographic and survey information provided by others. 17. Bearing values given in the referenced report remain applicable. 18. The foundation design criteria as outlined in the referenced report still apply. 19. Please refer to the referenced Geotechnical Engineering Report for further information. 20. Based upon intermittent observations and testing during the grading operations, from October 11 through November 7, 2002 on this project, it is our opinion that the grading has met the intent of the recommendations of the referenced Geotechnical Engineering Report, as well as the grading ordinances of the City of La Quinta. , 21. As used herein, the term "observation" implies only that we observed the progress of work we agreed to be involved with, and performed test on which together we based our opinion as to whether the work essentially complies with job requirements. 22. With any manufactured product, there are statistical variations in its uniformity and in the accuracy of tests used to measure its quality. As compared with other manufactured products, field construction usually presents large statistical variations in its uniformity and accuracy of test results used to measure its quality. Thus, even with very careful observation and testing, it cannot be said that all parts of the product comply with the job requirements and the degree of certainty is greater with full-time observation than it is with intermittent observations and testing. Therefore, our opinion based on observing EARTH SYSTEMS SOUTHWEST N November 7, 2002 - 4 - File No.: 08628-02 02-11-715 c and testing the work means that there is only a statistically -based, reasonable certainty that the work essentially complies with the job requirements. 23. We make no warranty, express or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. 24. It is recommended that Earth Systems Southwest (ESSW) be provided the opportunity for a general review of any changes to the final design and/or location of the proposed structures in order that earthwork and foundation recommendations may be properly interpreted. If ESSW is not accorded the privilege of making this recommended review, we can assume no responsibility for misinterpretation of our recommendations. 25. This report is issued with the understanding that it is the responsibility of the owner, or of his representative, to insure that the information and recommendations contained herein are called to the attention of the architect and engineers for the project and are incorporated into the plans and specifications for the project. It is also the owners responsibility, or his representative, to ensure that the necessary steps are taken to see that the general contractor and all subcontractors carry out such recommendations in the field. It is further understood that the owner or his representative is responsible for submittal of this report to the appropriate governing agencies. If there are any questions concerning this report, please do not hesitate to contact this office.
