1. DESCRIPTION
1.1 PROJECT NARRATIVE
The following report is for a proposed site plan located at Docs Road & Executive Drive in
Barbecue Township, Harnett County, NC. The proposed site is 325.12 acres in size, of which
18.63 acres will comprise the proposed limits of disturbance. The site drains directly into Rocky
Run Creek, a NC DEQ "Class U waterway located in the Cape Fear River basin. The site is
zoned Residential/Agricultural District (RA-20R) within the Harnett County zoning limits.
1.2 EXISTING CONDITIONS
The current site consists of previously subdivided single family lots and portions of undeveloped
wooded areas. Of the overall 325.12 acres on the site, approximately 138.16 acres have
previously been subdivided into public roads and private single family lots, leaving approximately
186.96 acres of mostly undeveloped area. This 186.96 acre portion is identified under Harnett
County GIS by PIN 0507-53-6396.000, and this land is almost exclusively wooded. Slopes on site
within our proposed disturbed area range from approximately 1 % to 25%. No steep slopes
(greater than 25%) are anticipated to be impacted per this site plan.

1.3 PROPOSED CONDITIONS
Our project is proposing to subdivide the remaining aggregate 186.96 acres of the site into 128
individual lots and public roads. Executive Drive will be extended eastward to the existing property
line, and a new north -south road terminating at cul-de-sacs on both ends will be constructed
perpendicular to Executive Drive. Hopeland Drive will be extended northward terminating at a cul-
de-sac, and a new east -west road (Ramshead Road) will be constructed terminating at a cul-de-
sac perpendicular to Hopeland Drive. Additionally, three new north -south roads terminating at cul-
de-sacs will be constructed perpendicular to Ramshead Road. Access to the site will be via an
existing entrance at the intersection of Docs Road and Executive Drive, and future connectivity to
the adjacent property will be available at the proposed termination of Executive Drive. Under
NCDEQ stormwater ordinance, stormwater detention is required for this proposed development.
The proposed stormwater conveyance system safely conveys the 10 year design storm and
adheres to the material, size, slope, cover, and crossing requirements dictated in the County's
stormwater ordinance.
1.4 CALCULATIONS
Routing calculations were performed using the computer program HydroCAD (version 10.0) by
HydroCAD Software Solutions LLC.
HGL calculations were performed using Bently StormCAD.
Below details the calculation summaries for the wet pond designs throughout the site. Under
NCDEQ stormwater ordinance, the site has been designed to meet the runoff treatment of the 1"
of rainfall. Six (6) wet ponds have been proposed throughout the site closest to the
streams/wetlands as an additional method of water quality.

The proposed stormwater conveyance system was designed to control and safely convey the
10-year, 24-hour return frequency storm event. The HGL calculations for the 10-year storm
event are summarized in Appendix F and Appendix G.
1.5 CONCLUSIONS
The requirements and criteria of Harnett County's stormwater management ordinance are met or
exceeded, and adverse post -development stormwater runoff impacts from the development have
been responsibly minimized or entirely eliminated. The proposed development contributes to no
greater than a 10% increase in the overall post -developed peak discharge from the site compared
to pre -developed rates for the 10-year and 25-year storm events. The 10-year storm event is
safely conveyed through the stormwater conveyance network, and outfalls at properly sized rip
rap aprons to ensure that scouring and erosion downstream are minimized.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nres.usda.gov/wps/
portal/nres/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https:Hoffices.sc.egov.usda.gov/locator/app?agency=nres) or your NRCS State Soil
Scientist (http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/?
cid=nres142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

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

Custom Soil Resource Report
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.
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
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
mentioned in the descriptions, especially where the pattern was so complex that it
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 Iandforms or
Iandform 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.
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

Custom Soil Resource Report
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
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.

from these crops can be used to control erosion until the next crop in the
rotation is established. These crops return large amounts of organic matter to
the soil.

horizons of mineral soil are as follows:
49

Custom Soil Resource Report
O horizon: An organic layer of fresh and decaying plant residue.
L horizon: A layer of organic and mineral limnic materials, including
coprogenous earth (sedimentary peat), diatomaceous earth, and marl.
A horizon: The mineral horizon at or near the surface in which an accumulation
of humified organic matter is mixed with the mineral material. Also, a plowed
surface horizon, most of which was originally part of a B horizon.
E horizon: The mineral horizon in which the main feature is loss of silicate clay,
iron, aluminum, or some combination of these.
B horizon: The mineral horizon below an A horizon. The B horizon is in part a
layer of transition from the overlying A to the underlying C horizon. The B
horizon also has distinctive characteristics, such as (1) accumulation of clay,
sesquioxides, humus, or a combination of these; (2) prismatic or blocky
structure; (3) redder or browner colors than those in the A horizon; or (4) a
combination of these.
C horizon: The mineral horizon or layer, excluding indurated bedrock, that is
little affected by soil -forming processes and does not have the properties typical
of the overlying soil material. The material of a C horizon may be either like or
unlike that in which the solum formed. If the material is known to differ from that
in the solum, an Arabic numeral, commonly a 2, precedes the letter C.
Cr horizon: Soft, consolidated bedrock beneath the soil.
R layer: Consolidated bedrock beneath the soil. The bedrock commonly
underlies a C horizon, but it can be directly below an A or a B horizon.
M layer: A root -limiting subsoil layer consisting of nearly continuous, horizontally

infiltration on a bare soil during periods after prolonged wetting when the soil is
not frozen. These properties include depth to a seasonal high water table, the
infiltration rate, and depth to a layer that significantly restricts the downward
movement of water. The slope and the kind of plant cover are not considered
but are separate factors in predicting runoff.

as follows:
Very low: Less than 0.2
Low: 0.2 to 0.4
Moderately low: 0.4 to 0.75

See Redoximorphic features.
Redoximorphic depletions
See Redoximorphic features.
Redoximorphic features
Redoximorphic features are associated with wetness and result from alternating
periods of reduction and oxidation of iron and manganese compounds in the
soil. Reduction occurs during saturation with water, and oxidation occurs when
the soil is not saturated. Characteristic color patterns are created by these
processes. The reduced iron and manganese ions may be removed from a soil
if vertical or lateral fluxes of water occur, in which case there is no iron or
manganese precipitation in that soil. Wherever the iron and manganese are
oxidized and precipitated, they form either soft masses or hard concretions or
nodules. Movement of iron and manganese as a result of redoximorphic
processes in a soil may result in redoximorphic features that are defined as
follows:

An area where, on the average, 75 percent or more of the original surface layer
has been lost because of accelerated erosion. Not used in map units in which
"severely eroded," "very severely eroded," or "gullied" is part of the map unit
name.
Shale
Sedimentary rock that formed by the hardening of a deposit of clay, silty clay, or
silty clay loam and that has a tendency to split into thin layers.
Sheet erosion
The removal of a fairly uniform layer of soil material from the land surface by the
action of rainfall and surface runoff.
Short, steep slope (map symbol)
A narrow area of soil having slopes that are at least two slope classes steeper
than the slope class of the surrounding map unit.
Shoulder
The convex, erosional surface near the top of a hillslope. A shoulder is a
transition from summit to backslope.
Shrink -swell
The shrinking of soil when dry and the swelling when wet. Shrinking and
swelling can damage roads, dams, building foundations, and other structures. It
can also damage plant roots.
Shrub -coppice dune
A small, streamlined dune that forms around brush and clump vegetation.
Side slope (geomorphology)
A geomorphic component of hills consisting of a laterally planar area of a
hillside. The overland waterflow is predominantly parallel. Side slopes are
dominantly colluvium and slope -wash sediments.
Silica
A combination of silicon and oxygen. The mineral form is called quartz.

Silica-sesquioxide ratio
Silt
The ratio of the number of molecules of silica to the number of molecules of
alumina and iron oxide. The more highly weathered soils or their clay fractions
in warm -temperate, humid regions, and especially those in the tropics, generally
have a low ratio.
As a soil separate, individual mineral particles that range in diameter from the
upper limit of clay (0.002 millimeter) to the lower limit of very fine sand (0.05
millimeter). As a soil textural class, soil that is 80 percent or more silt and less
than 12 percent clay.
Siltstone
An indurated silt having the texture and composition of shale but lacking its fine
lamination or fissility; a massive mudstone in which silt predominates over clay.
Similar soils
Soils that share limits of diagnostic criteria, behave and perform in a similar
manner, and have similar conservation needs or management requirements for
the major land uses in the survey area.
Sinkhole (map symbol)
A closed, circular or elliptical depression, commonly funnel shaped,
characterized by subsurface drainage and formed either by dissolution of the
surface of underlying bedrock (e.g., limestone, gypsum, or salt) or by collapse
of underlying caves within bedrock. Complexes of sinkholes in carbonate -rock
terrain are the main components of karst topography.
Site index
A designation of the quality of a forest site based on the height of the dominant
stand at an arbitrarily chosen age. For example, if the average height attained
by dominant and codominant trees in a fully stocked stand at the age of 50
years is 75 feet, the site index is 75.
Slickensides (pedogenic)
Grooved, striated, and/or glossy (shiny) slip faces on structural peds, such as
wedges; produced by shrink -swell processes, most commonly in soils that have
a high content of expansive clays.
Slide or slip (map symbol)
A prominent landform scar or ridge caused by fairly recent mass movement or
descent of earthy material resulting from failure of earth or rock under shear
stress along one or several surfaces.
Slope
The inclination of the land surface from the horizontal. Percentage of slope is
the vertical distance divided by horizontal distance, then multiplied by 100.
Thus, a slope of 20 percent is a drop of 20 feet in 100 feet of horizontal
distance.
.:

Custom Soil Resource Report
Slope alluvium
Sediment gradually transported down the slopes of mountains or hills primarily
by nonchannel alluvial processes (i.e., slope -wash processes) and
characterized by particle sorting. Lateral particle sorting is evident on long
slopes. In a profile sequence, sediments may be distinguished by differences in
size and/or specific gravity of rock fragments and may be separated by stone
lines. Burnished peds and sorting of rounded or subrounded pebbles or cobbles
distinguish these materials from unsorted colluvial deposits.
Slow refill
The slow filling of ponds, resulting from restricted water transmission in the soil.
Slow water movement
Restricted downward movement of water through the soil. See Saturated
hydraulic conductivity.
Sodic (alkali) soil
A soil having so high a degree of alkalinity (pH 8.5 or higher) or so high a
percentage of exchangeable sodium (15 percent or more of the total
exchangeable bases), or both, that plant growth is restricted.
Sodic spot (map symbol)
An area where the surface layer has a sodium adsorption ratio that is at least
10 more than that of the surface layer of the named soils in the surrounding
map unit. The surface layer of the surrounding soils has a sodium adsorption
ratio of 5 or less.
Sodicity
The degree to which a soil is affected by exchangeable sodium. Sodicity is
expressed as a sodium adsorption ratio (SAR) of a saturation extract, or the
ratio of Na+ to Ca++ + Mg++. The degrees of sodicity and their respective ratios
are:
Slight: Less than 13:1
Moderate: 13-30:1
Strong: More than 30:1
Sodium adsorption ratio (SAR)
A measure of the amount of sodium (Na) relative to calcium (Ca) and
magnesium (Mg) in the water extract from saturated soil paste. It is the ratio of
the Na concentration divided by the square root of one-half of the Ca + Mg
concentration.
Soft bedrock
Bedrock that can be excavated with trenching machines, backhoes, small
rippers, and other equipment commonly used in construction.

Soil
A natural, three-dimensional body at the earth's surface. It is capable of
supporting plants and has properties resulting from the integrated effect of
climate and living matter acting on earthy parent material, as conditioned by
relief and by the passage of time.
Soil separates
Mineral particles less than 2 millimeters in equivalent diameter and ranging
between specified size limits. The names and sizes, in millimeters, of separates
recognized in the United States are as follows:
Very coarse sand: 2.0 to 1.0
Coarse sand: 1.0 to 0.5
Medium sand: 0.5 to 0.25
Fine sand: 0.25 to 0.10
Very fine sand: 0.10 to 0.05
Silt: 0.05 to 0.002

Solum
The upper part of a soil profile, above the C horizon, in which the processes of
soil formation are active. The solum in soil consists of the A, E, and B horizons.
Generally, the characteristics of the material in these horizons are unlike those
of the material below the solum. The living roots and plant and animal activities
are largely confined to the solum.
Spoil area (map symbol)
A pile of earthy materials, either smoothed or uneven, resulting from human
activity.
Stone line
In a vertical cross section, a line formed by scattered fragments or a discrete
layer of angular and subangular rock fragments (commonly a gravel- or cobble -
sized lag concentration) that formerly was draped across a topographic surface
and was later buried by additional sediments. A stone line generally caps
material that was subject to weathering, soil formation, and erosion before
burial. Many stone lines seem to be buried erosion pavements, originally
formed by sheet and rill erosion across the land surface.
Stones
Rock fragments 10 to 24 inches (25 to 60 centimeters) in diameter if rounded or
15 to 24 inches (38 to 60 centimeters) in length if flat.

surrounding soil has no surface stones.
Strath terrace
A type of stream terrace; formed as an erosional surface cut on bedrock and
thinly mantled with stream deposits (alluvium).
Stream terrace

parallel to the stream channel, originally formed near the level of the stream;
represents the remnants of an abandoned flood plain, stream bed, or valley
floor produced during a former state of fluvial erosion or deposition.
Striperopping
Growing crops in a systematic arrangement of strips or bands that provide
vegetative barriers to wind erosion and water erosion.
Structure, soil

Structureless soil horizons are defined as follows:
Single grained: Entirely noncoherent (each grain by itself), as in loose sand
Massive: Occurring as a coherent mass
Stubble mulch
Stubble or other crop residue left on the soil or partly worked into the soil. It
protects the soil from wind erosion and water erosion after harvest, during
preparation of a seedbed for the next crop, and during the early growing period
of the new crop.
Subsoil
Technically, the B horizon; roughly, the part of the solum below plow depth.
Subsoiling
Tilling a soil below normal plow depth, ordinarily to shatter a hardpan or
claypan.

Custom Soil Resource Report
Substratum
The part of the soil below the solum.
Subsurface layer
Any surface soil horizon (A, E, AB, or EB) below the surface layer.
Summer fallow
The tillage of uncropped land during the summer to control weeds and allow
storage of moisture in the soil for the growth of a later crop. A practice common
in semiarid regions, where annual precipitation is not enough to produce a crop
every year. Summer fallow is frequently practiced before planting winter grain.
Summit
The topographically highest position of a hillslope. It has a nearly level (planar
or only slightly convex) surface.
Surface layer
The soil ordinarily moved in tillage, or its equivalent in uncultivated soil, ranging
in depth from 4 to 10 inches (10 to 25 centimeters). Frequently designated as
the "plow layer," or the "Ap horizon."

The A, E, AB, and EB horizons, considered collectively. It includes all
subdivisions of these horizons.
Talus
Rock fragments of any size or shape (commonly coarse and angular) derived
from and lying at the base of a cliff or very steep rock slope. The accumulated
mass of such loose broken rock formed chiefly by falling, rolling, or sliding.
Taxadjuncts
Soils that cannot be classified in a series recognized in the classification
system. Such soils are named for a series they strongly resemble and are
designated as taxadjuncts to that series because they differ in ways too small to
be of consequence in interpreting their use and behavior. Soils are recognized
as taxadjuncts only when one or more of their characteristics are slightly
outside the range defined for the family of the series for which the soils are
named.
Terminal moraine
An end moraine that marks the farthest advance of a glacier. It typically has the
form of a massive arcuate or concentric ridge, or complex of ridges, and is
underlain by till and other types of drift.
Terrace (conservation)
An embankment, or ridge, constructed across sloping soils on the contour or at
a slight angle to the contour. The terrace intercepts surface runoff so that water
soaks into the soil or flows slowly to a prepared outlet. A terrace in a field
70

Custom Soil Resource Report
generally is built so that the field can be farmed. A terrace intended mainly for
drainage has a deep channel that is maintained in permanent sod.
Terrace (geomorphology)
A steplike surface, bordering a valley floor or shoreline, that represents the
former position of a flood plain, lake, or seashore. The term is usually applied
both to the relatively flat summit surface (tread) that was cut or built by stream
or wave action and to the steeper descending slope (scarp or riser) that has
graded to a lower base level of erosion.
Te rracettes
Small, irregular steplike forms on steep hillslopes, especially in pasture, formed
by creep or erosion of surficial materials that may be induced or enhanced by
trampling of livestock, such as sheep or cattle.
Texture, soil
The relative proportions of sand, silt, and clay particles in a mass of soil. The
basic textural classes, in order of increasing proportion of fine particles, are
sand, loamy sand, sandy loam, loam, silt loam, silt, sandy clay loam, clay loam,
silty clay loam, sandy clay, silty clay, and clay. The sand, loamy sand, and
sandy loam classes may be further divided by specifying "coarse," "fine," or
"very fine."
Thin layer
Till
Otherwise suitable soil material that is too thin for the specified use.
Dominantly unsorted and nonstratified drift, generally unconsolidated and
deposited directly by a glacier without subsequent reworking by meltwater, and
consisting of a heterogeneous mixture of clay, silt, sand, gravel, stones, and
boulders; rock fragments of various lithologies are embedded within a finer
matrix that can range from clay to sandy loam.
Till plain
An extensive area of level to gently undulating soils underlain predominantly by
till and bounded at the distal end by subordinate recessional or end moraines.
Tilth, soil
The physical condition of the soil as related to tillage, seedbed preparation,
seedling emergence, and root penetration.
Toeslope
The gently inclined surface at the base of a hillslope. Toeslopes in profile are
commonly gentle and linear and are constructional surfaces forming the lower
part of a hillslope continuum that grades to valley or closed -depression floors.
71

Custom Soil Resource Report
Topsoil
The upper part of the soil, which is the most favorable material for plant growth.
It is ordinarily rich in organic matter and is used to topdress roadbanks, lawns,
and land affected by mining.
Trace elements
Chemical elements, for example, zinc, cobalt, manganese, copper, and iron, in
soils in extremely small amounts. They are essential to plant growth.
Tread
The flat to gently sloping, topmost, laterally extensive slope of terraces, flood -
plain steps, or other stepped landforms; commonly a recurring part of a series
of natural steplike landforms, such as successive stream terraces.
Tuff
A generic term for any consolidated or cemented deposit that is 50 percent or
more volcanic ash.
Upland
An informal, general term for the higher ground of a region, in contrast with a
low-lying adjacent area, such as a valley or plain, or for land at a higher
elevation than the flood plain or low stream terrace; land above the footslope
zone of the hillslope continuum.
Valley fill
The unconsolidated sediment deposited by any agent (water, wind, ice, or mass
wasting) so as to fill or partly fill a valley.
Variegation
Refers to patterns of contrasting colors assumed to be inherited from the parent
material rather than to be the result of poor drainage.
Varve
A sedimentary layer or a lamina or sequence of laminae deposited in a body of
still water within a year. Specifically, a thin pair of graded glaciolacustrine layers
seasonally deposited, usually by meltwater streams, in a glacial lake or other
body of still water in front of a glacier.
Very stony spot (map symbol)
A spot where 0.1 to 3.0 percent of the soil surface is covered by rock fragments
that are more than 10 inches in diameter in areas where the surface of the
surrounding soil is covered by less than 0.01 percent stones.
Water bars
Smooth, shallow ditches or depressional areas that are excavated at an angle
across a sloping road. They are used to reduce the downward velocity of water
and divert it off and away from the road surface. Water bars can easily be
driven over if constructed properly.

changes in rocks or other deposits at or near the earth's surface by atmospheric
or biologic agents or by circulating surface waters but involving essentially no
transport of the altered material.
Well graded

distributed over a wide range in size or diameter. Such soil normally can be
easily increased in density and bearing properties by compaction. Contrasts
with poorly graded soil.
Wet spot (map symbol)
A somewhat poorly drained to very poorly drained area that is at least two
drainage classes wetter than the named soils in the surrounding map unit.
Wilting point (or permanent wilting point)
The moisture content of soil, on an ovendry basis, at which a plant (specifically
a sunflower) wilts so much that it does not recover when placed in a humid,
dark chamber.
Windthrow
The uprooting and tipping over of trees by the wind.
