DALLAS COUNTY, TEXAS
sloping soil on escarpments of stream terraces. The
areas are long and narrow to oval and range from 10 to
more than 100 acres. In most areas, the original surface
layer has been removed by sheet erosion. Rills and
small gullies are common.
Typically, the surface layer is moderately alkaline, light
yellowish brown silty clay about 4 inches thick. It is
underlain, to a depth of 25 inches, by moderately alka-
line, very pale brown silty clay that has fine yellowish
brown mottles. To a depth of 65 inches, the soil is
moderately alkaline silty clay that is mottled yellowish
brown in the upper part and light brownish gray in the
lower part. To a depth of 80 inches, it is moderately
alkaline, brownish yellow silty clay loam.
Permeability is moderate, and the available water ca-
pacity is high. Runoff is medium. The hazard of erosion
is severe.
Included in mapping are small areas of Ferris, Heiden,
Lewisville, and Sunev soils. The included soils make up
less than 15 percent of the mapped areas.
This soil is used as pasture and for urban develop-
ment. Because of the erosion hazard it is not suitable for
cultivation.
This soil has medium potential for use as pasture.
Runoff, erosion, and the high content of calcium carbon-
ate are the main limitations.
This soil has low potential for urban development. The
high shrink-swell potential, low soil strength, corrosivity,
and the hazard of erosion are limitations to urban use.
This soil is in capability subclass Vie and in the Clay
Loam range site.
2-Arents, loamy, gently undulating. This map unit
is made up of areas that have been mined for gravel and
sand. Piles of discarded overburden and remaining soil
material have been smoothed, and most pits have been
filled with soil material. The areas are lower than the
surrounding landscape. Slopes range from 1 to 5 per-
cent. The areas are rectangular and range from 20 to
several hundred acres.
Because of mixing during mining operations, these
soils do not have uniform layers. In places, there are
fragments of soil layers. These soils are mainly sandy
clay loam, clay loam, loam, or fine sandy loam in the
upper 80 inches. Quartz pebbles are few to common
throughout.
The organic matter content is low. Permeability is
moderate. The water table is at a depth of 10 to 25 feet.
Most areas are subject to flooding unless protected by
levees.
Included in mapping are small areas of Bastsil, Dutek,
Silawa, Silstid, and Trinity soils. Also included are areas
of water in the deeper pits and areas where the surface
is covered with thin layers of gravel or sand.
The soils in this map unit are used as pasture and for
urban uses, including light industry, race tracks, golf driv-
ing ranges, sanitary landfills, and residential areas.These soils have medium potential for use as pasture.
Because of the low organic matter content, fertilizer is
needed for good forage production.
These soils have low potential for urban development.
The hazard of flooding in most areas is a limitation, but
flooding can be controlled by levees or other flood-con-
trol structures. Corrosivity to uncoated steel also is a
limitation.
This map unit was not assigned to a capability sub-
class or a range site.
3-Arents, loamy, hilly. This map unit consists of the
discarded overburden of mining operations. The overbur-
den has been left in mounds and ridges in the gravel
pits. The areas are rectangular and range from 15 to
several hundred acres. Slopes range from 10 to 30 per-
cent. The pits contain areas of water that make up 5 to
25 percent of most mapped areas.
Typically, the soil material, to a depth of 80 inches, is
moderately alkaline, light yellowish brown gravelly sandy
clay loam. There are fragments of soil layers throughout.
Included in mapping are small areas of Bastsil, Dutek,
Frio, Silstid, and Trinity soils. Also included are areas
where thin layers of gravel or sand are on the surface.
The included soils make up less than 15 percent of the
mapped areas.
Permeability is moderate, and the available water ca-
pacity is medium. Runoff is rapid. The hazard of erosion
is severe.
Most areas of this map unit are idle. A few areas are
grazed. These soils have medium potential for use as
pasture. The hilly slopes and the inaccessibility of the
areas to livestock are limitations to use as pasture.
These soils have very low potential for urban develop-
ment. The hazard of flooding in most areas is a major
limitation, but flooding can be controlled by levees or
other flood-control structures. The slopes of the ridges
and mounds are a limitation; this limitation can be over-
come by land leveling and smoothing. The corrosivity to
uncoated steel also is a limitation.
This map unit was not assigned to a capability sub-
class or a range site.
4-Arents, clayey, gently undulating. This map unit
consists of clayey soil material removed from nearby
road cuts, borrow pits, or drainage ditches. This material
has been piled into mounds several feet high. The areas
are rectangular and range from 15 to 75 acres.
Typically, the soil material is dark brown, calcareous
clay. It has many clods and bodies consisting of very
dark brown and very dark grayish brown fragments of
surface soil. In a few places, pebbles and broken con-
crete make up as much as 25 percent of the soil materi-
al.
Most areas of this map unit are idle and are covered
with thick stands of johnsongrass. A few areas are used
as building sites.
Permeability is slow to very slow, and the available
water capacity is high. Runoff is medium.11
