We are therefore requesting a permit be issued for the construction of a new well and septic system to serve the new home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and the parameters used in the design. Also identified on the plans are the location of the proposed well on the lot and the test hole locations. Existing drainage patterns are shown and will not be altered by'the development of the lot. Two test holes were placed near the location of the new absorption trench. These holes indicated poorly graded gravels and sands with a minor amount of silt. Percolation tests in the material resulted in rates between less than 1 and 7 minutes per inch. No groundwater was found during placement of the test holes, and none was noted during the monitoring period. We are therefore proposing to place a deep absorption trench system with 6' of gravel beneath the distribution pipe. The total depth of the trench will be 8'. The distribution pipe will be placed at 3' below the ground surface. In the event a deeper trench is required to provide gravity flow from the house a new test hole will be submitted with the as -built from the lot and approval will be solicited from the City prior to construction of the trench. The ground surface on the lot slopes as shown on the attached Site Plan with only shallow slopes near the proposed septic system site. The area around the trench and the home site were cleared and leveled prior to the percolation testing. The new absorption trench will be constructed on a fairly flat surface in conformance with Municipal requirements and parallel to ground contours where possible. 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. Lot 6, Block 8, Riverview Estates September 14, 2001 Page Two 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, nlL� Michael E. Anderson, P.E.

The reported results described the performance of the system under the conditions encountered at the time of the test, and separation distances measured to readily Identifiable features. The operational life of all wells and septic systems depend on the local soils condition, groundwater levels that may fluctuate during the year, and the water usage of the family being served by the system. These conditions are outside the control of the evaluator of the system. Satisfactory test _ results do not guarantee future performance of the system, nor do they guarantee that there are no hidden defects or encroachments. GEG, LTD. can therefore not provide any warranty or future estimate of how long the system will continue to meet the operational requirements of the ADEC or MOA DSD. The content of this report is for the sole benefit of the ownerfisted above.
