We are therefore requesting a permit be issued for the construction of a new septic system to accommodate the home. The lot will be served by a private well. The attached Site Plan and backup documentation identify the location and configuration of the proposed well and septic system along with the alternate site. No existing wells are closer than 100' from the proposed 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 tract in the area of the absorption trench and alternate site indicated silty gravel with sand (GM) material. The percolation rate of the soil was determined to be slightly more than 1 minute per inch. No groundwater was found during the placement of the test holes and none was noted during the monitoring period. 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 1,250 -gallon septic tank and a 50' long by 5' wide by 4' effective depth absorption trench to treat and dispose of the effluent generated in the house. The elevation of the distribution line in the absorption trench will be 3' below the surface and the total depth will be 7'. 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 absorption trench slopes to the northwest at a grade of 5%. The new trench 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 wells and any Lot 113, Fire Lake Heights October 28, 2012 Page Two surface water and 10' from the 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. Si�ncer�ely, Q Michael E. Anderson, P.E.

The minimum well productivity required by this Department (AMC 15.55) for a 4 -bedroom residence is .41 gallons per minute. Although the subject well currently exceeds this minimum requirement, all parties concerned are advised that the production capacity of the well may fluctuate. Restriction of non-critical water uses such as washing cars and watering lawns and gardens may be required.
