I, 1 Twenty-two(22) shallow borings were drilled and completed for.percolation tests by Neil O. Anderson&Associates, Inc. to characterize the subsurface and locate a suitable site for the proposed septic fields in the parcels. Most of the drilling landed in a permeable material between the depths of 3 to 25-feet. Several borings were drilled and did not encounter suitable material { on the first try. In these few cases, the borings were re-located 10 to 100-feet from the first ' boring and eventually encountered suitable material (see Plates 11 to 32 for boring information)_ I Generally the sediments observed at the lower elevations(borings 5-11 and borings17-22) of the site consisted.of a dark, often organic sandy surface clay, generally about 1-foot thick. Located below the surface layer was occasionally a 1 to 2-feet thick, cemented silty "hardpan" layer to a total depth of about 2-feet- Located below the hard pan la}er,were lenses of sand and } silt often containing:clay mixtures. Generally the sediments"ranged in composition, thickness, and depth throughout the site. The sand, silt, and clay mixtures encountered along the lower elevation sites often ranged between a few feet to about 10-feet in thickness. The original depositional environment appears to be fluvial (river/stream) environment. The higher elevations (borings 1-4 and borings 12-16)were composed of slightly different materials and consisted of generally sandy soils most often contained a matrix of finer grained material like silt or clay. Generally the sediments ranged in thickness, depth and composition throughout the site., These soils can be found at higher elevations and contain layers usually under { 11 feet thick. The:original depositional environment of this area also appears to be river/stream y environment. f For each of the twenty-two (22) Parcels, a percolation test was performed to demonstrate xl. each parcel's capacity for soil percolation for use with an on-site septic system For eighteen(8 of the twenty-two22).pcels,tbj&,gth of the test was determined g thcasing,adjacent 'p to the most mmeable material (usually sand) found to a maxim ept f 25(feet.
