Geotechnica Inc <br />cc <br />March 1. 2021 <br />San Joaquin County Environmental Health <br />Attention: Steven Shih <br />1868 East HazeIton Avenue <br />Stockton, CA 95205 <br />GEOTECHNICAL BORING PERMIT <br />KRUGER FOODS METAL BUILDING <br />18362 East Highway 4 <br />Stockton, California <br />In accordance with your request, we have prepared this letter to address the exploratory borings <br />we drilled without a permit. In conjunction with this letter, we have attached a well/boring permit <br />as well as payment confirmation of S2,128 for double the permit fee for five borings as requested. <br />Exploratory borings were drilled at five locations extending to an estimated depth of 15 feet on <br />October 29. 2019. A drilling permit was not obtained from the county. We were under the <br />impression that permits were only required for borings extending within ten feet of groundwater. <br />which is the requirement for most jurisdictions. We understand that the assumption is incorrect, <br />and that a permit is required for borings extending more than three feet below the ground surface <br />in San Joaquin County. <br />Contaminated soils were not encountered in our exploration. Groundwater data by the Department <br />of Water Resources indicates that the free groundwater table is more than 100 feet below the <br />ground surface. As such, the borings were backfilled with soil cuttings. <br />If you or others have any questions or concerns, please contact the undersigned. <br />Very truly yours. <br />RANEY GEOTEC NICAL, LNC <br />y Y7Lie <br />Registered Civil Engineer No. C89262 <br />TYGIJWCB <br />3140 BEACON BLVD. • WEST SACRAMENTO, CA 95691 • TELEPHONE 916/371-0434 FAX 916/371-809
