Buckholz Property Page 2 of 3 Our Project Number: LGS090517 August 21, 2009 The hole was pre-soaked 24 hours prior to the test with 12 inches of water above the bottom of the hole. Presoaking of the percolation test holes occurred approximately 24 hours prior to the percolation tests. The percolation tests were conducted for the borings on August 3, 2009 in accordance with the requirements of the EHD. A percolation test with duration of four hours was performed for each of the deep holes. The final half-hour of each four-hour percolation test was observed by MR. Michael Escotto Medina, Senior Inspector, Environmental Health Department (EHD). Measurement of the water level during the percolation test was from a fixed reference point on the PVC casing using an electric well sounder with a depth accuracy of 1/100th foot. All tabulated values on the field data sheet (attachment) are in decimal feet. After water drop was observed, the holes were checked for needing water refill. The refill level was approximately 0.5 ft (6 inches) of water above the bottom level of the percolation test holes. The readings were taken approximately every 30 minutes for a period of four hours. A deep percolation test is defined as being between 3.5 and 25 feet in depth; a satisfactory percolation rate for a deep test is 30 minutes per inch or less. Either a shallow or a deep percolation test must demonstrate a satisfactory rate within the proposed septic system disposal field to be suitable for a standard septic system. Details of the percolation tests are summarized in the following table.

The soils within the sewage disposal area of the site have demonstrated satisfactory' percolation rate in accordance with the requirements of the EHD for theuse of-a stands"rdJ septic system for each parcel. Septic System Construction should follow the San Joaquin County On-Site Wastewater Disposal Standards where applicable. 902 Industrial Way•Lodi, CA 95240 209.367.3701•Fax 209.333.8303 02008 Neil O.Anderson&Associates,Inc.
