Kingdon Rd., Lodi, CA (11.5 Acres) <br /> Mr. Kahion: <br /> Per your request, Live Oak GeoEnvironmental, Inc. (Live Oak) has completed a percolation test <br /> for the subject Site. We understand that you are planning to place a new modular home on the <br /> Site, located at 4040 West Kingdon Road, Lodi, California (Plate 1). The San Joaquin County <br /> Environmental Health Department has requested that a percolation test be completed prior to <br /> issuing septic permits. <br /> Soil Boring <br /> On September 15, 2020, Live Oak excavated a shallow sail boring on the Site for the purpose <br /> of conducting a percolation test. The boring was four inches in diameter, 3.27 feet deep, and <br /> was excavated by hand auger. The location of the boring is indicated on the attached Plate 2. <br /> Soil Lag <br /> The soil in the boring was observed to be sandy silt to the full depth of the hole. Cemented <br /> conditions were encountered from 2.5 feet down. <br /> Preparation and Presaturation of Percolation Test Hole <br /> After the shallow boring was advanced by hand auger, the test hole was completed for the <br /> percolation test. Approximately two inches of pea gravel were placed in the bottom of the <br /> open soil boring, followed by a 2.0-inch diameter PVC pipe with perforations on the bottom. <br /> Pea gravel was then used to backfill a few inches of the annular space. <br /> Live Oak presaturated the percolation test hole approximately 24 hours prior to the percolation <br /> testing. The hole was filled with water to a height of 12 inches above the bottom of the boring <br /> for the presaturation. On the day of testing, the hole was found to be intact and dry. <br /> Environmental Engineering Geology Geophysics <br />
