The seasonally saturated soils were located at <br /> 22" 8� 24" (mottled soil). Due to the seasonally saturated soils, a Pressurized Mound <br /> System will need to be installed to treat septic effluent. The bottom of the rock must be <br /> located at least 3' above the saturated soils. <br /> Due to the limited space available on this property, the toe of the mound will need to be <br /> 10' from the property line. <br /> An existing trench is located in the area of the proposed mound. This area will need to <br /> be roughened up, (see site plan). <br /> The soils at a depth of 12" have a percolation rate of�0.0 mpi. <br /> The existing tanks will need to be abandoned, pumped & filled with soil. The existing <br /> pump in the basement will also need to be abandoned. The main floor will flow gravity <br /> as much as possible with a new lift pump in the lower level. <br /> 1 <br />
