Our well was drilled by David Harper of Alpine Drilling The pump, pipes, and electrical system have not yet been installed. We were advised to not install these items until we were ready to operate because it could cause problems with our ongoing construction. We are now traveling and will not return until mid-March 2019. Our house construction work will restart in the spring of 2019. We will install the pump, water system, submit a well log, water quality test results, and fulfill any other requirements items as deemed necessary by MOA when our house construction is completed. We hope this letter will satisfy your questions. Thank you for your concern and understanding .

A new shop will also be constructed with plumbing facilities. We are therefore requesting a permit be issued for the construction of a new well and septic system to accommodate the home and shop. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. No existing wells or septic systems are closer than 100' from the proposed well or septic system. Drainage arrows are shown on the site plan showing the grade and direction of flow on the lot. The drainage pattern will not be changed as a result of this project. The test holes placed on the lot in the area of the absorption trench and alternate site indicated gravel with sand and silt (GM/GP). The percolation rate of the soil was determined to be between 1 and 5 minutes per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. Bedrock was found in both test holes at 7' below the surface. An application rate of 1.2 gallons per day per square foot was used in the design of the absorption system. We are proposing to place a new 1,500 -gallon STEP tank and a total of 100' long in 3 segments by 5' wide by .5' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be .5' below the surface and the total depth will be 1'. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trenches and 4' over the STEP tank. The ground surface on the lot in the area of the absorption trenches slopes to the southwest at a grade approximating 20%. The new trenches will be constructed Lot 4, Block 6, Paradise Valley Subdivision November 11, 2008 Page Two paralell with the slope contours as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from all wells and any surface water and 10' from the proposed and existing water services in the area. The house, shop and STEP tank will be lower than the absorption trenches with the septic effluent pumped to the absorption area through a 1.25" PVC line. If the system is constructed in accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, e "fes- ZE Michael E. Anderson, P.E.

Box 196650 Anchorage, AK 99519-6650 Subject: Lot 4, Block 6, Paradise Valley Subdivision Separation Distance Waiver Absorption Trench to Lot Line Dear On Site Services Engineer. Lot 4, Block 6, Paradise Valley Subdivision is plagued by bedrock at shallow depths which restricts the area available for an absorption trench. Test holes recently placed at the northeast comer indicate bedrock at sufficient depth to support an absorption system. This area, however, encroaches into the 10' setback from the property line. Soils at this location are well to poorly graded gravel with silt which is normally effective in the absorption and treatment of septic effluent. Placement of the absorption trenches within 1' of the southern lot line will not adversely affect neighboring lots. The lot to the south is currently vacant and no area has yet been found which will support an on site septic system. We hereby recommend a lot line waiver be issued allowing placement of the absorption system within 1' of the southern lot line. Sincerely, n Michael E. Anderson, P.E. 49th WCNAEL E.
