In a groundwater assessment done for the Albemarle County, ENSAT
Corporation divided the county into `hydrologic units'. Below is ENSAT's
description of the Chandler Unit which contains the parcel:
Soils underlying the area are dominated by the Manteo and Nason
series. Manteo soils are shallow and somewhat excessively drained.
The Manteo soils are formed in the weathered products of sericitic
schist/phyllite. The Nason soils are formed on uplands and range in
slope from 2-25%.
