The northern property line was not clearly marked and the absorption trenches were constructed 5' from the property line. The trench locations do not impact the property to the north as they are more than 50' from the septic system on that property. All lots in the subdivision are served by a community Class A Well more than 200' from the septic systems. We recommend a waiver be issued allowing the trench to remain 5' from the north property line. Sincerely, Michael E. Anderson, P.E. MICHAEL E. ANDERSON 6.

We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. The subdivision is currently served by a Class A Water System. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. Also identified on the plans are the existing wells and septic systems on surrounding lots. No conflicts exist between the proposed well and septic system and wells or septic systems on adjacent lots. 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 indicate the presence of silty sand with some gravel (SM). The percolation rate of the material was determined to be 19 minutes per inch. Groundwater was found during the placement of the test hole at 14' below the surface and rose to 8' during the monitoring period. An application rate of .6 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 2 new 63' and 55' long by 5' wide by 2.5' effective depth absorption trenches to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trenches will be 1' below the existing ground surface and the total depth will be 3.5' below ground. A minimum of 3' of fill or 2" of insulation and 2' of fill will be placed over the absorption trench and 4' over the septic tank. The ground surface on the lot in the area of the septic system slopes to the west at a very shallow grade. The new trenches will be constructed parallel with the slope 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' the Lot 5, Block 1, DeArmoun Subdivision No. 2 June 4, 2014 Page Two proposed and existing water services in the area. If the system is constructed in accordance with our design the following statements apply: 1. 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. 3. 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, ss Michael E. Anderson, P.E.
