Development Services Department On-Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 Subject: Thomas L. Boyle, Block 1, Lot 9A – 11900 Wagner Street Well and Septic System Design Dear On-Site Services Engineer: The owner of Lot 9A, Block 1, Thomas L. Boyle Subdivision intends to construct a new four- bedroom home on the lot. We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home. The existing well on the lot will be decommissioned per M.O.A. Code and a new well constructed. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. Also identified on the plans are the existing well and septic systems on this and surrounding lots. No conflicts exist between the proposed septic system and well or septic systems and wells on adj acent lots. The ground surface on the lot in the area of the septic system slopes to the west. The new trenches will be constructed parallel with the contours of the slope as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100’ from all private wells and any surface water. Ground surface contours are shown on the Site Plan which indicate direction of surface flow. Storm water drainage will not affect the proposed septic system. Please refer to the attached test hole log and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adj acent properties. Sincerely, Michael E.
