Dear Marilee, This letter is to summarize our investigation of the property on Deer Creek Road in Boulder Creek, for the purpose of determining septic system suitability. I inspected the parcel of approximately 4.5 acres on October 25, 2002 with you, and discussed locations that might be suitable for a home site and a septic system. We did find that the location of a future leachfield is important particulary that we not locate in the center of the lot which might be wet. In order to confirm soil suitability, I recommend at some point that we dig several test holes in the area that would be likely for a septic system. We may be required by Santa Cruz County Environmental Health Services (EHS) to dig a winter water table test, which means excavation in the rainy season to see if the ground is saturated within 12’ of the surface. This concern affects how we design the septic system and what type of system is used. If we encounter shallow groundwater, we may need to design some type of engineered septic system to compensate. I expect the soils which are silty sands will percolate in a medium range, which is desirable. We also need to coordinate where the well will be drilled, which must be 100’ from all parts of the septic system. To obtain a septic system permit, an application would be made to the County Environmental Health Service with a preliminary plot plan and a $1351.00 fee (subject to change). We would bring a backhoe tractor to the property to dig a 14’ deep test hole and then set up 3 percolation test in the leachfield area. After the perc tests are completed the septic system is designed, the plan completed and all documents submitted to EHS, the total costs including the permit are about $3600.00. the septic permit is approved in conjunction with an approved water supply. This means a well or other water source must be developed and tested. It is approved by the County through a permit called the Individual Water Supply ($103.00), which requires a flow and chemical and bacteria test. In summary, the site appears developable to me, and with successful soil and percolation tests, and development of an approved water supply, it appears to me that we can obtain a septic tank permit for a single family dwelling that you desire for this site. If you have any questions regarding this matter, please call me. Very truly yours, Kenneth Mabie REHS3579 |
