The installation will serve a proposed four (4) bedroom house. This lot and surrounding lots are served by private wells. Currently there are no wells within one hundred (100) feet of the proposed septic system. Soils: A test hole was performed on this lot by Pannone Engineering Services, LLC on March 10th, 2026. The approximate location is shown on the attached site plan. Groundwater was not observed during the excavation of the test hole, and bedrock was not encountered. Groundwater was not observed in the test hole monitor tube after 7- days. A percolation test was not performed in the lower fine -sand with silt layer due to the depth of the excavation and site conditions at the time the test hole was conducted. A sieve analysis of this material was collected with results indicating a USCS classification of (SM). Th e sieve analysis results on the subject lot appear nearly identical in sieve characteristics to the analysis performed as part of the test hole conducted on Equestrian Heights Block 3 Lot 11-- with a documented sub-1 MPI percolation rate. The underlying native soils encountered beneath the proposed absorption system consist of this USCS classified SM material. While this material will be penetrated during construction to accommodate the lower portion of the rock absorption media (see attached design package), this in-situ SM layer will inherently function as a natural sand filter beneath the system. The silty sand matrix, including its fine fraction, provides additional filtration and attenuation of wastewater effluent migrating from the overlying (GP) or gravel layer in which the upper portion of the proposed system will be located within. Given similar sieve analysis results, a sub-1 MPI percolation rate on Lot 11 within this material, and overall soils appearance; a conservative application rate of 0.8 gpd/SF was used for the design of a conventional wastewater treatment system in the area of the test hole. A confirmation percolation test will be performed by PES at the bottom of the proposed trench (within the SM classified layer) to verify that the selected application rate is appropriate for the system design. Soil Absorption System Design: See design package. Surface Water: There is no surface water within one hundred (100) feet of the proposed septic system. Topography: See attached site plan for area topography. Drawing Markings: The Drawings are marked “For MOA Review Only”. When written notification that the review is complete and no further comments are received from MoA On-Site Department, the note will be removed and “For Construction” drawings will be issued.
