LOGE 20-52: Jaimes Percolation Test Page 2 October 27, 2020 Live Oak presaturated the percolation test hole approximately 24 hours prior to the percolation testing. The hole was filled with water to a height of 12 inches above the bottom of the boring for the presaturation. On the day of testing, the hole was found to be intact and dry. Percolation Test Procedure Live Oak conducted the percolation test for the boring on October 23, 2020. Percolation test procedures conformed to San Joaquin County Environmental Health Department policy. Due to initial percolation rates observed, a one-hour test was selected. Water level measurements were taken every 10 minutes during this one-hour period. Daria Afonskaia, Registered Environmental Health Specialist at the San Joaquin County Environmental Health Department, observed the final 30 minutes of the percolation test. An electronic well sounder with a depth accuracy of 1/100`h foot was utilized for the water level measurements. The water level was measured against a fixed reference point on the well casing. Measurements were recorded on the data sheet in decimal feet. When necessary after measuring the water level, the hole was refilled with water to a level of approximately six inches above the bottom of the hole. Percolation Test Results The completed percolation test form is attached to this letter. The form was signed by Ms. Afonskaia and indicates a percolation rate for the hole based on the least water drop observed. Per San Joaquin County Environmental Health Department's definition, a deep percolation test hole has a depth between 3.5 and 25 feet; a satisfactory percolation rate for a deep test is greater than 1 minute per inch (min/in) but less than or equal to 30 min/in drop. Details and results of the percolation test are summarized in the following table. Table 1. Percolation Test Summary Test No., Percolation Percolation Test Duration Comments Date Tested Test Rate (see note) Depth (ft.)

The soils on the Site have demonstrated a satisfactory percolation rate for the use of standard septic systems in accordance with the requirements of the San Joaquin County Environmental Health Department. This percolation test is considered representative of soils within an approximate 100-foot radius of the test location. Based on the percolation rate encountered between 1.0 and 5.0 min/in, the San Joaquin County Environmental Health Department will require a 20-foot separation from the bottom of
