Country Club Blvd. (LA-97-14) <br /> Stockton, CA <br /> Dear Mr. Burgess, <br /> Per your request, our office performed a soil suitability/nitrate loading study and an engineered <br /> septic system design for a proposed lot line adjustment involving the subject property. The project <br /> consists of building a four(4)bedroom residence. The assessors parcel number for the project site is <br /> APN 121-020-14. <br /> Based on the unsatisfactory percolation rate of 250 minutes per inch and shallow ground water <br /> encountered at a depth of 4.8 feet measured during the drilling, it was determined the project is suitable <br /> for development utilizing an engineered septic system. The engineered drawing and calculations are <br /> attached to this letter. <br /> The submittal of the engineered system design is required prior to project approval. PHS/EI-ID <br /> requires an additional $435.00 fee to review the engineered septic system design. Several field <br /> inspections will be required during construction of the systems to ensure our design is installed correctly. <br /> It is critical that in the clayey soil environment, smearing of the clayey soils is avoided. Attached to this <br /> letter is the septic system design and supporting graphics. <br /> Our professional services were performed, our findings obtained, and our recommendations <br /> proposed in accordance with generally accepted engineering principles and practices. This warranty is in <br /> lieu of all other warranties either expressed or implied. Test findings and statements of professional <br /> opinion do not constitute a guarantee or warranty, expressed or implied. If you have any questions, <br /> lease do not hesitate to call. <br /> ED GFO <br /> ,p Best Regards, <br /> GN NEIL O.ANDERSON & ASSOCIATES,INC. <br /> cc Q No. 2151 Z P <br /> CERTIFIED <br /> ENGINEERING f►1 <br /> N>, GEOLOGIST <br /> Da�elch, M.Sc., Senior Geologist <br /> �OFCAL � �` '7 CEG-2151, CHG-653 <br /> dc NQm <br /> Neil O. derson, resident <br /> FCAA RGE 245 <br /> NOA,DJW:djw <br /> attachments: drawing, calculations <br />
