Map Unit Description(Brief,Generated)--Albeq, e County,Virginia NIS Cole's Import
Map Unit Description (Brief, Generated)
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions in this
report, along with the maps, can be used to determine the composition and
properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas.A map unit is identified and named
according to the taxonomic classification of the dominant soils.Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however,the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena.Thus,the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently,every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
The Map Unit Description (Brief, Generated) report displays a generated
description of the major soils that occur in a map unit. Descriptions of non-soil
(miscellaneous areas) and minor map unit components are not included. This
description is generated from the underlying soil attribute data.
Additional information about the map units described in this report is available in
other Soil Data Mart reports,which give properties of the soils and the limitations,
capabilities,and potentials for many uses.Also,the narratives that accompany the
Soil Data Mart reports define some of the properties included in the map unit
descriptions.
Report—Map Unit Description (Brief, Generated)
Albemarle County, Virginia
Map Unit: 27B—Elioak loam, 2 to 7 percent slopes
Component: Elioak(80%)
The Elioak component makes up 80 percent of the map unit. Slopes are 2 to 7
percent. This component is on hillslopes, piedmonts.The parent material consists
of residuum weathered from mica schist. Depth to a root restrictive layer is greater
than 60 inches.The natural drainage class is well drained. Water movement in the
most restrictive layer is moderately high.Available water to a depth of 60 inches is
moderate. Shrink-swell potential is low.This soil is not flooded. It is not ponded.
There is no zone of water saturation within a depth of 72 inches. Organic matter
content in the surface horizon is about 2 percent. Nonirrigated land capability
classification is 2e. This soil does not meet hydric criteria.

•
Information in this table is intended for land use planning, for evaluating land use
alternatives, and for planning site investigations prior to design and construction.
The information, however, has limitations. For example, estimates and other data
generally apply only to that part of the soil between the surface and a depth of 5 to
7 feet. Because of the map scale,small areas of different soils may be included
within the mapped areas of a specific soil.
The information is not site specific and does not eliminate the need for onsite
investigation of the soils or for testing and analysis by personnel experienced in the
design and construction of engineering works.
Government ordinances and regulations that restrict certain land uses or impose
specific design criteria were not considered in preparing the information in this table.
Local ordinances and regulations should be considered in planning, in site
selection, and in design.
Report—Dwellings and Small Commercial Buildings
[Onsite investigation may be needed to validate the interpretations in this table and
to confirm the identity of the soil on a given site.The numbers in the value columns
range from 0.01 to 1.00.The larger the value,the greater the potential limitation.
The table shows only the top five limitations for any given soil. The soil may have
additional limitations]

Dwellings and Small Commercial Buildings
Soil properties influence the development of building sites, including the selection
of the site,the design of the structure,construction,performance after construction,
and maintenance.This table shows the degree and kind of soil limitations that affect
dwellings and small commercial buildings.
The ratings in the table are both verbal and numerical. Rating class terms indicate
the extent to which the soils are limited by all of the soil features that affect building
site development. Not limited indicates that the soil has features that are very
favorable for the specified use. Good performance and very low maintenance can
be expected. Somewhat limited indicates that the soil has features that are
moderately favorable for the specified use. The limitations can be overcome or
minimized by special planning, design, or installation. Fair performance and
moderate maintenance can be expected. Very limited indicates that the soil has
one or more features that are unfavorable for the specified use. The limitations
generally cannot be overcome without major soil reclamation, special design, or
expensive installation procedures. Poor performance and high maintenance can
be expected.
Numerical ratings in the table indicate the severity of individual limitations. The
ratings are shown as decimal fractions ranging from 0.01 to 1.00. They indicate
gradations between the point at which a soil feature has the greatest negative
impact on the use (1.00)and the point at which the soil feature is not a limitation
(0.00).
Dwellings are single-family houses of three stories or less. For dwellings without
basements,the foundation is assumed to consist of spread footings of reinforced
concrete built on undisturbed soil at a depth of 2 feet or at the depth of maximum
frost penetration,whichever is deeper. For dwellings with basements, the
foundation is assumed to consist of spread footings of reinforced concrete built on
undisturbed soil at a depth of about 7 feet. The ratings for dwellings are based on
the soil properties that affect the capacity of the soil to support a load without
movement and on the properties that affect excavation and construction costs.The
properties that affect the load-supporting capacity include depth to a water table,
ponding, flooding, subsidence, linear extensibility (shrink-swell potential), and
compressibility. Compressibility is inferred from the Unified classification. The
properties that affect the ease and amount of excavation include depth to a water
table, ponding, flooding, slope,depth to bedrock or a cemented pan, hardness of
bedrock or a cemented pan, and the amount and size of rock fragments.
Small commercial buildings are structures that are less than three stories high and
do not have basements. The foundation is assumed to consist of spread footings
of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth
of maximum frost penetration,whichever is deeper.The ratings are based on the
soil properties that affect the capacity of the soil to support a load without movement
and on the properties that affect excavation and construction costs.The properties
that affect the load-supporting capacity include depth to a water table, ponding,
flooding, subsidence, linear extensibility(shrink-swell potential), and
compressibility(which is inferred from the Unified classification).The properties that
affect the ease and amount of excavation include flooding, depth to a water table,
ponding,slope, depth to bedrock or a cemented pan, hardness of bedrock or a
cemented pan, and the amount and size of rock fragments.
