Sediment & Erosion Control Narrative
Existing Conditions Description
The proposed hot-mixed asphalt plant project is located at 12971 NC Hwy 62 in Burlington,
Caswell County, NC. The parcel identification number is 0090 027. The site consists of
�► approximately 84.2 acres of mainly agricultural fields and wooded land. Hughes Mill Creek runs
along the northern property line. There are two existing pond within the site, one jurisdictional
subject to a 70" vegetative buffer and one non jurisdictional. The existing soils are Helena sandy
�*�► loam "HeB / HeC /HeD" in Hydrologic Soils Group "D," Chewacla loam "ChA" in Hydrologic
Soils Group B/D, and Rowan-Poindexter complex "RxE" in Hydrologic Soils Group `B." The
majority of the site drains north toward Hughes Mill Creek in the Stoney Creek Balance and Jordan
�+ Lake watersheds. The surface water classification is WS-II-BW; HQW; NSW. FIRM Panels
3710990100J and 3710990000L indicate that the property does lie within a special flood hazard
area; however, the project site does not.
Erosion Control Summary
This project proposes a hot-mixed asphalt and concrete plant facilities, a new building and
associated parking. Approximately 22.2 acres of land will be disturbed. Four temporary sediment
basins will be installed to treat the majority of the disturbed area. The remainder of the project
site will be protected by silt fence, NCDET special silt fence, and silt fence stone outlets. At the
completion of construction, one sediment basin will be converted to a permanent wet pond, while
the others will be removed, and the site will be seeded to create a good stand of grass.
Erosion control measures for this site have been designed in accordance with NCDEQ standards
and specifications.
NPDES/NCGO1 Plan
The site has been designed to comply with NCDEQ NPDES Guidelines. A NCGOI permit will
be obtained upon NCDEQ Erosion Control approval.

Map Unit Descriptions
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,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.
n., 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.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components.They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management.These are called contrasting, or dissimilar, components.They
generally are in small areas and could not be mapped separately because of the
scale used.Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
r-, given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each.A few areas of minor
components may not have been observed, and consequently they are not
r,
mentioned in the descriptions, especially where the pattern was so complex that it
�+ 8

Custom Soil Resource Report
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data.The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
landform segments that have similar use and management requirements. The
delineation of such segments on the map provides sufficient information for the
development of resource plans. If intensive use of small areas is planned, however,
onsite investigation is needed to define and locate the soils and miscellaneous
^' areas.
An identifying symbol precedes the map unit name in the map unit descriptions.
Each description includes general facts about the unit and gives important soil
properties and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major
horizons that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness,
salinity,degree of erosion,and other characteristics that affect their use. On the
basis of such differences, a soil series is divided into soil phases. Most of the areas
shown on the detailed soil maps are phases of soil series.The name of a soil phase
commonly indicates a feature that affects use or management. For example,Alpha
silt loam, 0 to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes,associations,or undifferentiated groups.
rn
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps.
The pattern and proportion of the soils or miscellaneous areas are somewhat similar
in all areas.Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present
or anticipated uses of the map units in the survey area, it was not considered
practical or necessary to map the soils or miscellaneous areas separately. The
pattern and relative proportion of the soils or miscellaneous areas are somewhat
similar.Alpha-Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas
that could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management.The pattern and proportion
of the soils or miscellaneous areas in a mapped area are not uniform.An area can
be made up of only one of the major soils or miscellaneous areas,or it can be made
r*+ up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.
