Thanks-Steve ":.;:Tlmber Ridge S~, Block 2, Lot 11 GUIDELINES Wastewater System Sizing: This is a new 4-bedroom, single family home. This is an older subdivision and some of the neighboring lots are developed. Many lots are still undeveloped. These lots are large and are served by private water wells. No adverse impacts are expected from development. No conflicts to the other lots will take place by this septic system and water well construction. The easements are located on the drawing and are not encroached upon. Soil tests revealed sandy gravel soil with low silt. An application rate of 1.2 GPD/FT~ with 0.7 reduction factor for utilizing a 5' wide trench, 2' effective depth. Trench Length = 500 FT:/Yx .7 reduction factor = 70'; 1 line ~ 70'. Bedrock was encountered at 8.5', 6" groundwater was encountered ~ 8.0'.
