r and OWTS." The project is not proposing to deviate from these requirements. This continues to be the baseline for this 1 project. In addition, the Environmental Health Department's (EHD) approval EHD approval of individual wells for this subdivision is based on the following findings. As per UC Davis "Irrigation Management of Walnut Trees with a Limited Water Supply", a Walnut orchard uses 41 to 44 in. of water per acre per year. That translates out to 6,245 gallons per day for two acres. Actual average water use numbers from Community Service Area 46, a public water system operated by SJC, is 2,108 gal per day. CSA 46 is located within 5 miles of this subdivision and has an average lot size of 1.25 acres per parcel. EHD expects that this subdivision will use slightly higher numbers but in a similar range. Based on this information agricultural production would use more water than residential use. A check of the water levels of wells located in this area from the Department of Water Resources database shows the water table to be between 80 ft. to 100 ft. deep and reasonably stable over the last 20 years. Water quality testing performed by EHD on similar single use domestic wells in the area meets water quality standards for drinking water. If the proposed subdivision was not approved, the existing site would still be allowed would still retain its water rights for farming. This is also the baseline. As a result of this analysis, staff conducted the CEQA review and determined that a multiple layer of CEQA exemptions were appropriate and applicable to this project. These CEQA exemptions include Sections 15061(b)(3), 15183, and 15304. If you believe you have any other concerns, please participate in the planning commission process tomorrow tonight.

Upon further review of the original application, one of the major issues was the impact of multiple new wells. At that time, 4 years ago the developer argued that the irrigation of the then walnut orchard drew more water than the new wells would. Of course, that irrigation well has been removed, and the water has not been used for 4 years. Thus the then usage base been abandoned. In the meantime, the water situation in the area and the state in general has gotten worse and the need to monitor it has increased. I have seen nothing in the staff report, or matters I have received that addresses this crucial environmental issue. There needs to be a CEQA review of this matter. Please advise. Thank you 2
