Horizon Construction Services, LLC (HCS)performed percolation tests on June 4, 1999. (See attached report). The average percolation rate was found to be 80.0 minutes per inch The average percolation rate does not meet the County regulation rates for a standard system. A limiting zone of groundwater was encountered at three feet from the surface. See bore log. An engineer-designed system will be required due to the percolation rate and limiting zone. The system has been sized for a five bedroom single family residence and a detached shop/office to be constructed in the future. The house is designed to use a 1500-gallon two-compartment septic tank and the shop/office will have a separate 1000-gallon two- compartment septic tank. The effluent from the tanks will go into a distribution box and be distributed into a 3853 square foot combination bed using 65 high capacity Infiltrator® units. The system was designed using the water balance method and can handle the flow. See enclosed calculations. The following criteria must be met: The combination bed will be constructed with high capacity H-10 Infiltrator®units spaced six feet apart(see drawing)and installed in accordance to the manufacturer recommendations. Wicking sand will need to be placed between the units and a minimum of six inches over the units. A minimum of six inches (6") of native topsoil material will then be placed over the wicking sand. The system will need to be mounded so the bottom of the infiltrators will be a minimum of one foot above the existing surface. A minimum of a 3-mil plastic liner will be installed around the combination bed from the top of the wicking sand to one foot below existing grade.

The percolation test was performed by Horizon Construction Services, LLC (Horizon) on June 4, 1999. The average percolation rate was found to be 80.0 minutes per inch and is summarized on Table No. 1. The average percolation rate does not meet the County regulation rates for a standard system. A limiting zone of ground water was encountered at the site at a depth of three feet (3'-0"). See attached Soil Profile. It is our recommendation that an engineered designed septic system be required in accordance to the county regulations for the above referenced site.
