We propose to install one deep trench and 1500-gallon tank to serve the existing 5-bedroom residence. The design is based on the recent test hole conducted on April 25, 2022. Soils encountered were typical Sand Lake sand with a little silt and no groundwater was observed at test hole excavation or monitoring. The slopes are moderate at 15%+/- at the proposed upgrade location. The lot and area are served by private water. The design will not impact any of the neighboring properties. Please contact us if you have any questions. Sincerely, Curtis Huffman, P.E.
