In a groundwater assessment done for the Albemarle County, ENSAT
Corporation divided the county into `hydrologic units'. Below is ENSAT's
description of the unit in which lies most of tract B:
The Lynchburg unit is characterized by a relatively narrow band that
trends in a northeast direction and includes a relatively long segment
of the Mechums River valley. Soils within this unit are dominated by
the Hazel and to a lesser extent by the Elioak and Glenelg soils. The
Hazel soil series are moderately deep and well drained and are formed
in the weathered products of metagreywacke sandstone and mica
schist. Hazel soils lie on the uplands and their slopes range from 7-
45 %. The Elioak soil series are deep and well drained and are formed
in the products of weathered micaeous metamorphic rock. Slopes of
the Elioak range from 2 -25 %. The Glenelg soils are also deep and
well drained and are formed in the weathered products of quartz mica
schist. Slopes of the Glenelg range from 2 -45 %.
