Box 196650, Anchorage, Ak 99519-6650 (907) 343-7904 Attention: Dan Roth Ref: Subdivision ofR & R Tract 5B (Proposed Tracts 10 and 11, R & R Subdivision) Mr. Roth: The homeowner is proposing to subdivide the referenced property. We have been retained to provide engineering services to meet the platting requirements for the on-site water and wastewater systems. There is an existing 3 bedroom house located on proposed Tract 10 that is served by a private well and septic system. In order to meet the subdivision requirements we performed soils testing and groundwater monitoring for the proposed parcel, Tract 11. Attached is a site plan which shows a septic reserve area, proposed well location for Tract 11. We have also attached a topographical site plan which shows that there are no slopes concerns. We are unaware of any adverse impacts this subdivision would have on adjacent wells or septic systems. If you have any questions, please contact us at 337-6179. Thank you for your assistance. ~efl~ff~' ~P'E'' M'S' 3701 E.
