Below is the evaluation summary for the 818 E. French Camp Rd., French Camp Irrigation Well (APN <br /> 17749088)-well permit application. <br /> The evaluation, with assumptions as noted, indicates that the proposed Irrigation well is located in an <br /> area of low domestic/residential well density (65 wells per section), General Plan designation R/L (2.1- <br /> 6 Dwelling units per acre) but is not likely to interfere significantly with existing off-site wells, create <br /> unreasonable groundwater level declines/reductions in aquifer storage or to create issues with <br /> infrastructure due to subsidence and it can be approved pending any other issues that you might have <br /> with the application. <br /> Summary: <br /> - The applicant proposes: well depth of 280 feet, a well grout seal of 50 feet with extraction rate— <br /> 150 GPM with anticipated pumping schedule 35,000 Gal/day in a 15-acre lot. <br /> - Proposed new well is in an area of low domestic/residential (2.1—6 Dwelling units per acre) well <br /> density(36 wells per section).At least one domestic well is located approximately 674 feet North <br /> of the proposed Ag well <br /> - Based on the extraction rate of 250 GPM, The Theis drawdown chart predicts less than 5 feet of <br /> drawdown if the well is more than 0.5 feet away from proposed well. <br /> - Online databases do not specify any irrigation wells located within 60 feet of the proposed well <br /> location. Review of aerial imagery indicates an irrigation well is present approximately 2200 feet <br /> West. <br /> - Groundwater levels estimated by DWR well data range between 25 (1/3/200)to 46 (10/24/2022) <br /> foot below ground surface over the past fifty years. Water levels fluctuate approximately 1 to 6 <br /> feet between seasonal high and low levels. <br /> - The permit application proposes a minimum well casing/grout seal of 50 feet and appears to <br /> target the Modesto-Riverbank aquifer with water-bearing zones anticipated to be under <br /> unconfined to locally confined conditions. <br /> - The annual total extracted volume is estimated to be approximately 13.1 million gallons, a peak <br /> pumping rate of 157 GPM, and an annualized/seasonal pumping rate of approximately 52 GPM. <br /> - The aquifer volume below the 15-acre parcel contains an estimated 938 acre-feet of water <br /> storage. The proposed extraction volume of 15 acre-feet per year is approximately 4.3 % of the <br /> estimated aquifer storage beneath the parcel without regard to recharge each season and is <br /> considered sustainable. <br /> - The proposed well is not located within the extents of the Corcoran Clay, subsurface water- <br /> bearing sediments are semi-consolidated to consolidated, and the proposed well is not located in <br /> an area where subsidence is currently indicated, therefore subsidence is unlikely to be of <br /> significance or to create issues. <br />
