TMP 46 - 34A
Application Number: SUB200800178 Theodore J. Sklany -Final
Groundwater Reviewer: J. Rubinstein
Date: 18 July 2008
Description: 1 division — 2 lots
Water Quantity
The Albemarle County Database show 21 wells within half a mile of the
lots. The wells range from 45 to 305 feet in depth with a median depth of
180 feet. The well yields range from zero to 100 gallons per minute with a
median yield of 20 gallons per minute. The well on the property is listed as
having a yield 25 gallons per minute and a depth of 180 feet.
Water Quality
As shown on the Virginia Department of Environmental Quality (DEQ) GIS
website, there are two leaking underground storage tank sites (LUST) within
two thousand feet of the parcel.' Section 500 through 503 of Albemarle
County Code requires that new wells within two thousand feet of a LUST
site be tested for the volatile organic compounds Benzene, Toluene,
Ethylbenzene and Xylenes before a building permit can be issued. 2
Buffers
The parcels are in the Powell Creek watershed. According to the county
GIS site, a buffer is required along the Powell Creek, the western boundary
of the parcels.3

Site Description
In a groundwater assessment done for the Albemarle County, ENSAT
Corporation divided the county into `hydrologic units'. The parcels are in
two of the hydrologic units. Below is ENSAT's description of the unit in
which lies Parcel A and the western portion of TMP 57 -7913:
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 %.
According to the Virginia Department of Mineral Resources 1993 Map, the
bedrock beneath this portion of the parcels is the metagraywacke (Zlm),
phyllite and metasandstones (Zlg) of the Lynchburg Group.
