IL*, Inc. April 16, 2019 Amir Aznavian 25072 Adelanto Drive Laguna Hills, CA 92677 Subject: Report of Summarized Field and Laboratory Compaction Test Results for Swimming Pool Abandonment at 4226 West Kent Avenue, Santa Ana, CA HGEI Proiect No. 19-O3-38O1 Dear Mr. Aznavian: Imported fill material placed in the above-referenced swimming pool has been tested by a member of our staff as requested. This report summarizes the results of field and laboratory tests which were performed periodically on February 27 thru April 4,2019. Prior to backfilling the pool shell was provided with drainage consisting of (5) small sections removed in the pool shell bottom and the area filled with open graded gravel with a geotextile fabric on top of the gravel prior to soil placement. The former pool varied in depth from 2-8 feet. Backfill Placement & Compaction The former pool was located in the rear yard of the existing property as shown on the attached plan, made from google maps, Plate A. Laboratory & Field Testing Fill material consisting of import soil was tested in our laboratory for maximum dry density/optimum moisture content. The result of the test is summarized in the attached Table 1. Field density testing was performed using the Nuclear Gauge Method (ASTM Test Method D6938) during our site visits and were compared to the laboratory maximum dry density to determine the relative compaction of the backfill material during compaction. All density tests resulted in compaction of at least 85 percent. Broken pieces of the pool shell was incorporated into the fill which was mixed with the import soil. Random probing of the soils was done to verifo uniformity of the backfill being compacted. The test results are summarized in the attached Table 2. 1590 N.
