Mike Smith <br /> September 11,2002 <br /> Page 2 <br /> prior to the percolation test. A four(4)hour percolation test was conducted on both the shallow <br /> and deep percolation tests on September 11, 2002. The end of the test was observed by Mr. <br /> Steven Shih, Inspector for SJC PHS-EHD. Please refer to the attached percolation test form for <br /> the field measurements. The following table summaries the results of the percolation test. <br /> Summary of Percolation Tests <br /> Boring Time Period of Test,Date Test Depth Percolation Rate <br /> Shallow* Four(4)hour test, September 11,2002 25 feet 62.5 minutes per inch <br /> Deep** Four(4)hour test, September 11,2002 3 feet 8.9 minutes per inch <br /> * Acceptable shallow percolation rate is less than or equal to 60 min/in. <br /> ** Acceptable deep percolation rate is less than or equal to 30 min/in. <br /> In summary, the site appears to be suitable for a standard septic system with leach lines <br /> and seepage pits in accordance with the requirements of the County of Sacramento, Department <br /> of Health, Environmental Health Branch. The shallow percolation rate of 62.5 minutes per inch <br /> was found to be unsatisfactory and above the County's maximum rate of 60 minutes per inch (60 <br /> t � t___ __ Li_\ TL_ a L__ <br /> minutes per inch and leas i� acceptable'). iiic UVUP FCIUVIduVii Lc�L wd� ivuriu Lo rrdVe air a <br /> satisfactory percolation rate of 8.9 minutes per inch(30 minutes per inch and less is acceptable) <br /> therefore the area is suitable for a septic system utilizing seepage pits. <br /> Our professional services were performed,our findings obtained, and our <br /> recommendations proposed in accordance with generally accepted engineering principles and <br /> practices.
