The design proposes to do a soils test hole prior to construction.  Although the adjacent properties have 1‐5 MPI soils, the proposed design conservatively uses the application rate for 31‐60 MPI soils. The design proposes to use a BioMicrobics BioBarrier 0.5 MBR AWWTS.  Please see the design drawings for further details. 20‐ft Subsurface Drain to Steep Slope Waiver Request:  The subsurface drain is located approximately 20‐feet from a 56% slope.  Soils tests in the local area indicate the soils are predominately Hydrologic Soils Group A, which uses a 45% infiltration line for design purposes.  The detail included in the design drawings shows that effluent will not daylight due to the slope in question.  As such, we are requesting the subsurface drain be allowed to be 20 feet from the existing steep slope. There are no anticipated probable adverse impacts to adjacent properties if the septic system is constructed as designed.  This includes: a. Wells; b. Wastewater disposal systems; c. Replacement disposal sites; and d. Drainage flowing onto and off of the subject property that could adversely affect performance of the wastewater disposal system.
