Soil Suitability/ Nitrate Loading Study , <br /> Jeremy Winery , Lodi, CA Irerracon <br /> May 7, 2019 Terracon Project No. NA197008 <br /> 1.3.4 Existing Septic Tank Usage in the Vicinity <br /> In an attempt to determine the septic system density for the vicinity of the site, our office reviewed <br /> a recent aerial photograph of the property available from GoogleEarthT"'. The vicinity of the site <br /> consists of vacant land and residences. The assumption was made that each building/cluster of <br /> buildings has one septic system. Using this method, we determined there are approximately five <br /> septic systems within 0.25 miles of the site. <br /> 1.3.5 Septic Permit History in the Vicinity <br /> Terracon searched the EHD Public Records website for the adjoining property septic permits. The <br /> following table is a summary of septic permits available for the adjacent properties: <br /> Table 2. <br /> Summary of Adjoining Property Septic Permits. <br /> Leach <br /> Tank Size Leach Line Line Seepage Pits, <br /> Direction Address Permit# Type (Gallons) Quantity Length Depth x Width <br /> (Feet) <br /> (Feet) <br /> North --- NF --- --- --- --- --- <br /> Northeast 21500 N.

The septic <br /> repair permits can be found in Appendix C of this report. <br /> 1.3.7 Expected On-Site Maximum Septic Tank Usage <br /> Based on a review of information provided by Mr. Vierra, the site is proposed to be developed <br /> with a winery which will be open nine hours per day, seven days per week, year round. <br /> Approximately 5 full time employees and 15 daily visitors are anticipated. The proposed winery <br /> will have five special events each year with up to 150 people per event. The total maximum daily <br /> septic tank usage is 2,540 gallons per day (Refer to Section 2.3.4 for the calculation). <br /> Responsive ■ Resourceful ■ Reliable 6 <br />
