Below is the evaluation summary for the 28782 Two Rivers Road Irrigation Well (APN 25710001) -well permit application. The evaluation, with assumptions as noted, indicates that the proposed Irrigation well is located in an area of low domestic/residential well density (1 well per section), General Plan designation AG (0.0— 0.05 Dwelling units per acre) but is not likely to interfere significantly with existing off-site wells, create unreasonable groundwater level declines/reductions in aquifer storage or to create issues with infrastructure due to subsidence and it can be approved pending any other issues that you might have with the application. Summary: - The applicant proposes: well depth of 220 feet, a well grout seal of 50 feet with extraction rate— 1200 GPM with anticipated pumping schedule 720,000 Gal/day in a 40 acre lot. - Proposed new well is in an area of low domestic/residential AG (0.0—0.05 Dwelling units per acre) well density(17 wells in section T3S/R7E/08).At least one domestic well is located approximately 350 feet North of the proposed Ag well - Based on the extraction rate of 1200 GPM,The Theis drawdown chart predicts less than 5 feet of drawdown if the well is more than 1000 feet away from proposed well. Per the statements from the owner of the well that would be impacted, existing well has not negatively impacted the well predicated to be impacted. The owner of the well that is predicted to be impacted does not oppose the replacement well. See signed statements between two landowners. - Online databases do not specify any irrigation wells located within 2,000 feet of the proposed well location. Review of aerial imagery indicates an irrigation well is present approximately 3,500 feet West. - Groundwater levels estimated by DWR well data range between 12 (3/13/2013)to 20 (03/24/1997) foot below ground surface over the past fifty years. Water levels fluctuate approximately 1 to 4 feet between seasonal high and low levels. - The permit application proposes a minimum well casing/grout seal of 50 feet and appears to target the Modesto-Riverbank aquifer with water-bearing zones anticipated to be under unconfined to locally confined conditions. - The annual total extracted volume is estimated to be approximately 39 million gallons, a peak pumping rate of 466 GPM, and an annualized/seasonal pumping rate of approximately 155 GPM. - The aquifer volume below the 40-acre parcel contains an estimated 2,155 acre-feet of water storage.The proposed extraction volume of 3 acre-feet per year is approximately 5.6%of the estimated aquifer storage beneath the parcel without regard to recharge each season and is considered sustainable.The Groundwater Sustainability Authority with jurisdiction over this area has approved the well. - The proposed well located within the extents of the Corcoran Clay.Corcoran clay may be at a depth of 200 feet and the proposed well.There is no evidence subsidence is currently indicated, therefore subsidence is unlikely to be of significance or to create issues.
