We are therefore requesting a permit be issued for the construction of a septic system to accommodate the home. The lot and subdivision is served by the AWWU water system. The attached Site Plan and backup documentation identify the location and configuration of the proposed septic system along with the alternate site. No conflicts exist between wells or septic systems in the area. The lot is very small with only 7,020 square feet of surface area. The absorption trench must be placed within 2' of the south property line. A lot line waiver request accompanies this permit application. 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 sand with gravel and silt (SM/SP). 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 but was noted at 7' 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 STEP tank and a 70' ;pmh by 5' wide by 2' 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 1' below the surface and the total depth will be 3'. 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 is fiat with little or Lot 20, Block 2, Patricia Subdivision July 13, 2009 Page Two no slope in any direction. The new trench will be constructed parallel with the contours of the surface as much as possible in conformance with Municipal requirements. The new septic system will be constructed a minimum of 100' from any 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: 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. 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. 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, Michael E. Anderson, P.E.

It is surrounded by subdivisions currently served by AWWU water and sewer systems. It is also surrounded by 60' and 93' rights of way on two sides. We are therefore requesting a waiver allowing the absorption system to be placed within 2' of the south lot line. We are also requesting the alternate site be placed within 2' of the south property line. Soils at this location are well to poorly graded sand with silt which is normally effective in the absorption and treatment of septic effluent. Placement of the absorption trench and alternate site within 2' of the south lot line will not adversely affect neighboring lots. All adjacent lots are served by the AWWU water system. We hereby recommend a lot line waiver be issued allowing placement of the absorption systems within 2' of the south lot line. Sincerely, Michael E.

The septic system was originally designed by Watkins Engineering in May of 2006 with a permit issued at the time. The permit has since expired. We are therefore requesting a new permit be issued for the construction of a new septic system to accommodate the home. The subdivision is served by the AWWU water system with sewer service also provided on lots to the north. The attached Site Plan and backup documentation completed by Watkins Engineering 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 septic system. The majority of the lots surrounding the lot to the south and the east are currently vacant. The lot is fairly fiat in all directions. 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 bed and alternate site indicated clean sand (SM/SP) material with some silt at the 8' level. The percolation rate of the soil was determined to be 1.5 minutes per inch. Groundwater was found during the placement of the test hole at 7' below the surface and remained at that level during the monitoring period. An application rate of .8 gallons per day per square foot was used in the design of the absorption system. We reviewed the design completed by Watkins Engineering and agree the most effective system for the lot is a 15' wide by 50' long shallow bed system constructed in an east-west direction. A 1,500 gallon STEP tank will be required to collect the sewage from the house and transport the effluent to the absorption bed. The elevation of the distribution line in the absorption bed will be 2' below the surface and the total depth will be 2.5'. A minimum of 3' of fill or 2' of insulation and 2' of fill will be placed over the absorption bed and 4' over the STEP tank. Lot 20, Block 2, Patricia Subdivision October 3, 2008 Page Two The STEP tank will be placed on Lot I along with the house, The absorption bed will be on Lot 20. Letters of non objection and encroachment permits from the utility companies have been obtained and previously submitted since the distribution line from the tank will cross the lot line and utility easements. The ground surface on the lot in the area of the absorption trench is nearly flat' with a slight bias to the south. The new bed 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' from the proposed and existing water services in the area. 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. 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. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The currant drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.
