Five test holes were augered usirgo a hz)bile P-50 drilling rig from Denali Drilling. A solid ~light ~" auger was used to drill the test holes. Soils were visually analyzed and samI~tes were taken for laboratory sieve analysis. All the test holes were then pre-soaked and the following day, on March 22, 1983, l~rcolation tests were performed. The soils encountered were prir~arily silty-gravel and grs.vz~4~ sa~-SM. The ~erco]ation rates for the the subdivision wer~250~/t~P~7~ ft/be~lroom ~ith one test hole ov~ 350~q ft/bedroom. Water w~nly ~untered in one of the testholes at The s[~division's vegetation i.s characterized by climax growth of Birch trees inters~versed with Spruce trees. The open areas are vegetated with Alder am~ grass areas. The soils encountered indicated that 'this subdivision is developable. ~e large size of the lots (2.1 to ~.7 acres) minimize the chances of any adverse enviro~qental impact caused by on-site wastewater disposal.
