Subject: Re: T15N R1 W SEC 8 LT 98 onsite Closeout Document review comments Attachments: Sven Hall - well 2.pdf [EXTERNAL EMAIL] Curtis, Here is the information on the second well. We had this well drilled in search of water with less sediment for our domestic water for our new home. Unfortunately, the well is currently low production and there is no waterline established to the home from this well. We have not completely written this well off and may further explore deeper. We do not currently have a pump in the well and we do not have a water quality test. We do not plan to decommission this well as we have spent over 15k to have this well drilled and I am not willing to fill it with concrete and waste that much money. I am asking for us to have the term of the permit to further produce a new as -built to include this well location if we choose to keep it along with obtaining a pump.

Survey as built only shows one well on the property. what happened to the other one? Need to justify that both welts meet separation to the new field. Need a new survey as built. Thanks for the corrected IR. Plan view showing force to gravity transition accepted. You note that groundwater was observed at 6.8' BGL on your record drawing.

Subject: 20317 Bowlby (T15N R1 W SEC8 Lot 98. Curtis, Jay Crewdson has applied for an encroachment permit for 3' of drain field into the 50' right of way reserve adjacent to McKinley View Avenue. At this time, here is Right of Way's comment concerning the drain field encroachment. 1. The owners are put on notice the leach field, shed, fence, or other structure is an unpermitted encroachment into the Right of Way Reserve, Utility, Public Use, or Drainage Easement, and ROW is not enforcing it at this time. Should the encroaching item(s) need moving or the owners want to replace them, the final location needs to be out of the easement(s). Please take this review as the final comment on the action.

Well: The design locates the proposed well near the south property line.  This location is greater than 100‐ feet from the proposed on‐site septic system.  There are no known existing septic systems on adjacent properties within 150‐feet of the proposed location.  The adjacent property due south of the proposed well location will continue to have adequate space if needed for a future drainfield upgrade. Septic System: The design specifies a 1250‐gallon septic tank, and locates the drainfield in native sandy soil found on the northeast side of the property.  The 7‐day groundwater elevation in October 2023 was at 8.8‐feet below ground level. The proposed well and septic systems, if constructed as designed; Will satisfy all code required horizontal and vertical separation distances, Will not cause any probable adverse impacts to adjacent properties, Will not negatively impact existing wells and septic systems on adjacent properties, Will not be adversely affected by potential drainage that could flow onto and off of the subject property.
