FFtothe 3.3) The septic system that serves the residential structure on proposed Parcel l has oning properly without any problems since the house was built in the 1940's according ra's. No records were on file at EHD pertaining to the subject address.subject property is in an area designated as"Hardpan"by EHD's map denoting the various soil types and septic system requirements throughout the County. (§ 5.4) Therefore, since the water table is deep in this area at approximately 105 feet, and the fact that the shallow soil structure can be inadequate for proper effluent management, seepage pits and/or sumps are always 3�� allowed to be installed in this area. (§ 3.5 and 3.6) A review of Application Permits on microfiche file with EHD reveals there have been two Applications in the one-half mile radius study area for Repairs/Additions/Replacements 3 s3 6) to septic systems on Jack Tone Road. (§ 5.4) This can be considered a relatively low number of Repairs/Additions/Replacements, and can be attributed to the very low housing density in this area. 5 4' However, due to the indigenous clay soil type in this area, if the housing density were higher, repairs and additions permits would almost certainly be greater. Due to this clay soil, most effluent volume is managed by sumps or seepage pits in this area. In addition, EHD permits for septic system installations in this locale almost always included seepage pits. (§ 5.1 and 6.0) SOIL PROFILE AND PERCOLATION TESTING (§ 5.4) As noted on the USDA Soil Survey map, the surface soils are composed predominately of a Hicksville loam (#107),with the extreme northeast portion consisting of Finrod clay loam(#158). Permeability is moderately slow in both of these soil types. There is also a high shrink-swell potential. Consequently, consideration should be given to having a soils engineer assess the on-site soils to provide foundation recommendations if construction will ever take place on the Parcels. As discussed below, the shallow perc test for Parcel 2 had an unacceptable percolation rate, while the deep perc tests on all three Parcels had excellent percolation rates. (§ 5.2,5.3, and 5.4) Logs of Boring using the Unified Soil Classification System(USCS), as observed from 25 foot boring completed on Parcel 1 are found in Appendix C. In addition, soil logs are also found on the respective EHD PERCOLATION TEST DATA SHEETS. Generally, the soils show a consistent clay soil with a cemented silts hardpan within the shallow surface soils of the property. Clayey silt was found predominately in the deeper test borings, except the referenced 3, sandier material found at the perc test depths on both Parcels. Consequently,the deep percolation tests were set within strata at the highest elevations where permeability was favorably encountered. (§ 6.1) Percolation testing was conducted in the locations as illustrated on the Tentative Map found in Appendix C. As referenced, there is no proposal to build on any of the subject Parcels, therefore,the test locations were determined by the most logical place where building may occur in the future. The following information describes the preparation of the percolation test borings and the actual perc testing: Page-2- Chesney Consulting
