Application Number: SUB200800002 Jones, Vincent L/ 2 lot - Final
Groundwater Reviewer: J. Rubinstein
Date: 18 April 2008
Description: 1 division - 2 lots
Water Quantity
The Albemarle County Database shows 54 wells within half a mile of the
lot. The wells range from 75 to 420 feet in depth with a mean depth of 205
feet. The well yields range from zero to 45 gallons per minute with a mean
yield of five gallons per minute.
Water Quality
As shown on the Virginia Department of Environmental Quality (DEQ) GIS
website, there are four leaking underground storage tank sites (LUST) within
2000 feet of the parcel! Therefore Section 500 through 503 of Albemarle
County Code requires that the well be tested for the volatile organic
compounds Benzene, Toluene, Ethyl-benzene and Xylenes before a building
permit can be issued. a
Buffers
According to the county GIS site, there is no required buffer on the
property.3
The site is in the watershed for the North Fork of the Hardware River. The
parcel is not within any of the buffers for the public water supply reservoirs
nor is it within a public water supply watershed.

Site Description
According to the Virginia Department of Mineral Resources 1993 Map, the
bedrock beneath the parcel is in the gneiss unit of the Blue Ridge Basement
Complex (Ybg).
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 containing the parcel:
The Ragged Mountain unit is characterized by mountainous terrain
located in the southwestern portion of the County and is underlain by
the metagranitic rocks of the Blue Ridge Basement Complex. The
soils in the area are dominated by the Chester, Hayesville, Ashe, and
Parker soil series. These soils are derived from weathered granite and
granite gneiss and are deep and excessively well drained. These soils
range in slope from 2 -45% with some slopes up to 60 percent in the
Parker soils.
