This soil survey is a publication of the National Cooperative Soil Survey, 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 (formerly the Soil Conservation Service) has

leadership for the Federal part of the National Cooperative Soil Survey.

Major fieldwork for this soil survey was completed in 2001. Soil names and

descriptions were approved in 2002. Unless otherwise indicated, statements in this

publication refer to conditions in the survey area in 2001. This survey was made

cooperatively by the Natural Resources Conservation Service and the Illinois

Agricultural Experiment Station. Financial assistance was provided by the Will County

Board and the Illinois Department of Agriculture. The survey is part of the technical

assistance furnished to the Will-South Cook Soil and Water Conservation District.

Soil maps in this survey may be copied without permission. Enlargement of these

maps, however, could cause misunderstanding of the detail of mapping. If enlarged,

maps do not show the small areas of contrasting soils that could have been shown at a

larger scale.

This soil survey contains information that affects land use planning in this survey

area. It contains predictions of soil behavior for selected land uses. The survey also

highlights soil limitations, improvements needed to overcome the limitations, and the

impact of selected land uses on the environment.

This soil survey is designed for many different users. Farmers, foresters, and

agronomists can use it to evaluate the potential of the soil and the management needed

for maximum food and fiber production. Planners, community officials, engineers,

developers, builders, and home buyers can use the survey to plan land use, select sites

for construction, and identify special practices needed to ensure proper performance.

Conservationists, teachers, students, and specialists in recreation, wildlife

management, waste disposal, and pollution control can use the survey to help them

understand, protect, and enhance the environment.

Various land use regulations of Federal, State, and local governments may impose

special restrictions on land use or land treatment. The information in this report is

intended to identify soil properties that are used in making various land use or land

treatment decisions. Statements made in this report are 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.

Great differences in soil properties can occur within short distances. Some soils are

seasonally wet or subject to flooding. Some are shallow to bedrock. 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.

These and many other soil properties that affect land use are described in this soil

survey. The location of each soil is shown on the detailed soil maps. Each soil in the

survey area is described. Information on specific uses is given for each soil. Help in

using this publication and additional information are available at the local office of the

Natural Resources Conservation Service or the Cooperative Extension Service.

WILL COUNTY is in the northeastern part of Illinois

(fig. 1). It has an area of 543,635 acres, or 849 square

miles. It is bordered by Cook and Du Page Counties

on the north, Indiana on the east, Grundy and Kendall

Counties on the west, and Kankakee County on the

south. In the year 2000, the population of the county

was 502,266 (U.S. Department of Commerce, 2000).

Joliet, the county seat, is the largest city in the county.

This survey area is a subset of Major Land

Resource Area (MLRA) 110, the Northern Illinois and

Indiana Heavy Till Plain (USDA, 1981). This soil survey

updates the survey of Will County published in 1962

(Wascher and others, 1962). It provides additional

information and has larger maps, which show the soils

in greater detail. It is available on a CD-ROM that

includes digital topographic quadrangles (Illinois

Natural Resources Conservation Service).

General Nature of the County

This section provides general information about Will

County. It describes history; physiography, relief, and

drainage; natural resources; agriculture; urbanization;

transportation facilities; industry; and climate.

History

The area now known as Will County was a favorite

hunting ground for the Indians. It had an abundant

supply of water and timber. Travel was facilitated by

the old Sauk Trail and by the Des Plaines, Du Page,

and Kankakee Rivers. Indian burial mounds indicate

that people lived in the survey area 4,000 to 13,000

years ago and that several distinct types of Indians

inhabited the area for centuries.

Will County was established in January 1836 by an

act of the Illinois Legislature, which subdivided it from

Cook County. The county name honored Dr. Conrad

Will, a member of the first Constitutional Congress and

a member of the Illinois Legislature. The county lost a

small area when Kankakee County was organized in

1852. The present county boundaries were

established in 1853 (Will County, 2002).

The first permanent settlers of European descent

entered the survey area shortly before 1830. Joliet

was laid out in 1834.

The Illinois and Michigan Canal, built between 1836

and 1848, had a significant impact on Will County and

the Midwest in general. It stretched from Chicago to

in cooperation with the Illinois Agricultural Experiment Station
18 Soil Survey of

LaSalle-Peru Illinois, approximately 100 miles. Once

opened, in 1848, it provided a link between the

Eastern and Midwestern parts of the country. It linked

the waters of Lake Michigan with those of the Illinois

and Mississippi Rivers. Many communities sprang up

along the route of the canal. In Will County, they

include Bolingbrook, Channahon, Crest Hill, Joliet,

Lockport, Rockdale, and Romeoville. The canal

provided farmers a way to transport their crops. Large

quantities of corn and wheat were shipped by canal.

Lumber, beef, pork, stone, coal, sugar, and salt were

other commodities shipped on the canal. The canal

brought people and prosperity to the region. It

transformed the region into a hub for goods and

people traveling throughout the country. It is now used

for recreational purposes. The towpath trail along the

canal is a State park that runs through a rural and

wooded landscape for about 61 miles. The Illinois and

Michigan Canal National Heritage Corridor

encompasses portions of 49 municipalities, sections of

5 counties, and 18 neighborhoods in Chicago (Canal

Corridor Association, 2002).

Physiography, Relief, and Drainage

Will County is made up of ground moraines, end

moraines, outwash plains, stream terraces, flood

plains, and bogs. The county is in the Till Plains and

Great Lake Sections of the Central Lowland Province

(Leighton and others, 1948). Two further subdivisions

make up the county. The Wheaton Morainal Country

occurs in the eastern two-thirds of the county, and the

Kankakee Plain makes up the rest of the county.

Will County has relatively low relief (fig. 2). Elevation

ranges from about 500 feet above sea level in the

areas where the Des Plaines and Kankakee Rivers

leave the county to about 830 feet on the Valparaiso

Moraine. directly west of Monee. Examples of other

elevations in the county are Beecher, 720 feet;

Frankfort, 760 feet; Manhattan, 690 feet; Plainfield,

610 feet; and Wilmington, 550 feet.

Several moraines extend through the county. The

Minooka Moraine forms a north-south ridge along the

Will-Kendall County border. It does not extend south of

the Des Plaines River. The Rockdale Moraine begins

in northern Will County, where it emerges from under

the Valparaiso Moraine and extends southward

between the Du Page and Des Plaines Rivers. Three

small valleys, formerly glacial drainageways, are

traceable through the Rockdale Moraine. A wide break

occurs in the Des Plaines River Valley. South of this

valley, the moraine extends to Elwood and southeast

to about Symerton. The Manhattan Moraine begins

directly south of Joliet and extends in a southeasterly

direction into Kankakee County. It is broken in several

places by small valleys of streams arising in the

Valparaiso Moraine to the northeast. The Valparaiso

Moraine, a very broad moraine, is the largest of the

morainal ridges in Will County, covering most of the

northeastern part of the county. It extends into Du

Page and Cook Counties on the north and eastward

into Indiana. A fairly prominent front occurs along

much of its outer margin. In the past this moraine

formed a drainage divide between the Illinois and

Mississippi River systems and the St. Lawrence River

system. The Tinley Moraine touches the extreme

northeast corner of Will County at Steger.

Most drainage waters in Will County now flow into

the Illinois River through the Du Page, Des Plaines,

and Kankakee Rivers. The waters from Plum Creek

and other north-flowing streams formerly flowed into

Lake Michigan and then into the St. Lawrence River.

After construction of the Chicago Sanitary and Ship

Canal and the opening of the Calumet Sag Channel,

however, these waters were diverted mostly to the

Illinois River (Wascher and others, 1962).

Natural Resources

Will County has several different kinds of natural

resources, including construction materials, surface

and ground water, and shipping lanes.

Dolomite is quarried at several places, primarily

along the Des Plaines River Valley. Much of it is

crushed for use in concrete and for agricultural

limestone, although some is used for building blocks.

Good examples of block buildings are in downtown

Joliet. The county has several sand and gravel pits.

The largest ones are in the outwash plain east of

Plainfield and along Des Plaines River Valley. Sand for

building purposes and for molds is mostly screened

from gravel in the same pits. Little use is made of clay

deposits at present.

Coal deposits, which occurred only in the

southwestern part of the county, where they were at a

depth of 25 to more than 100 feet and averaged about

3.5 feet in thickness, have been depleted.

Peat and muck occur in limited amounts in the

county. In some areas they are mined for local use as

lawn and garden dressing.

Surface water and underground water are both

relatively abundant in Will County. The Kankakee, Des

Plaines, and Du Page Rivers are continuously flowing

streams, and the Chicago Sanitary and Ship Canal is

kept at a high level by diversion from Lake Michigan.

Wells range from shallow (20 or less feet in depth) to

deep (more than 200 feet). The shallowest wells tend

to be in areas of gravelly outwash plains, such as

those in the vicinity of Plainfield. The deepest wells,

those that penetrate water-bearing rock strata, are

1,000 or more feet deep. These generally enter St.

Peters sandstone, Potsdam sandstone, or some layer

of the Prairie du Chien series. Most of the water from

deep wells is hard or highly mineralized. It is

particularly high in dissolved calcium and magnesium

(Wascher and others, 1962).

Agriculture

Like much of Illinois, Will County has some very

fertile farmland. Agriculture has been the dominant

land use in the county for decades. In 1997, about 58

percent of land in the county was used for agriculture.

Figure 2.—Generalized relief map of Will County, Illinois,

showing the location of the highest and lowest elevations

in the county.
20 Soil Survey of

In recent years, the market value of Will County

agricultural products has consistently exceeded $107

million per year and more 28 percent of the farms in

the county generated annual sales of $100,000 or

more (USDA, 1997). Corn, soybeans, small grain

crops, and nursery and greenhouse crops account for

92 percent of the market value of the agricultural

products sold in 1997, and livestock, poultry, and

related products account for the remaining 8 percent.

While the market value of farm products is

increasing, the number of farms and the number of

acres farmed have been decreasing. In 1959, the

county had 2,366 farms totaling 412,509 acres. In

1997, it had 910 farms totaling 293,526 acres. Thus,

the number of farms decreased by nearly 63 percent

and the number of acres farmed decreased by nearly

29 percent. This decline has been counteracted by a

large increase in average farm size. In 1959, the 2,366

farms in the county averaged 174 acres in size; in

1997, the 910 farms in the county averaged 323 acres

in size (USDA, 1997).

Urbanization

The population of Will County increased rapidly and

consistently from 1840 through 1960. In 1960, the

reported total population was 191,617. Of this number,

135,565 people were listed as urban and 56,052 as

rural. Included as rural were all persons living in towns

with a population of less than 2,500 as well as persons

living on farms (Wascher and others, 1962). The

population of the county was 357,313 in 1990 and

502,266 in 2000 (U.S. Department of Commerce,

2000). With a 40.6 percent population increase from

1990 to 2000, Will County is the fastest growing

county in Illinois. According to the Northeastern Illinois

Planning Commission, this growth was accompanied

by a 43 percent increase in the amount of housing.

Transportation Facilities

Will County has a well developed, multimodal

transportation system. The county is served by Illinois

State Highways 1, 7, 43, 50, 53, 56, 59, 83, 126, 171,

and 394; U.S. Highways 6, 12, 30, 45, and 52; and

Highways 80, 55, 57, and 355, which are part of the

interstate highway system. A well integrated county

highway system provides connections between

incorporated and unincorporated areas throughout the

county.

Public transit services within Will County are

provided by Metra Commuter Rail and Pace Suburban

Bus under the umbrella of the Regional Transportation

Authority.

Water transportation is available in Will County. The

Chicago Sanitary and Ship Canal is suitable for heavy

barge traffic.

Several major general aviation airports serve Will

County. These airports serve local recreational and

business flying needs; however, they do not support

commercial flights or large jets. The proposed South

Suburban Airport would provide commercial service.

Industry

The information in this section was provided by Aimee Ingalls of

the Joliet/Will County Center for Economic Development.

Will County has a strong traditional economic base

involving a number of activities, including

manufacturing, health care, retail sales, construction,

education, and administrative services. Economic

enterprises include the manufacture of earth-moving

equipment, oil refining, utilities (such as gas and

electric), and wireless communications. Numerous

large business, factories, and power plants of various

kinds are along the Des Plaines River Valley. Housing

construction is very important in nearly all parts of the

county. Sand, gravel, and limestone are mined for

concrete work and other purposes. Other businesses

and industries have developed in most Will County

municipalities and account for many of the traditional

manufacturing jobs. Major industrial development

areas are in Bolingbrook, Elwood, Joliet, Lockport,

Plainfield, and Romeoville.

Between 1998 and 1999, Will County showed the

following growth in employment: 14 percent in

construction; 59 percent in arts, entertainment, and

recreation; and 20 percent in warehousing. In addition,

the county has gained jobs in wholesaling, finance,

health care, and other services.

Climate

Resources Conservation Service, Portland, Oregon.

Table 1 gives data on temperature and precipitation

for the survey area as recorded at Joliet in the period

1971 to 2000. Table 2 shows probable dates of the first

freeze in fall and the last freeze in spring. Table 3

provides data on the length of the growing season.

In winter, the average temperature is 25.2 degrees

F and the average daily minimum temperature is 17.0

degrees. The lowest temperature on record, which

occurred at Joliet on January 20, 1985, was -26

degrees. In summer, the average temperature is 72.1

degrees and the average daily maximum temperature

is 82.8 degrees. The highest temperature, which
Will County, Illinois 21

occurred at Joliet on June 26, 1988, was 104

degrees.

Growing degree days are shown in table 1. They

are equivalent to “heat units.” During the month,

growing degree days accumulate by the amount that

the average temperature each day exceeds a base

temperature (50 degrees F). The normal monthly

accumulation is used to schedule single or successive

plantings of a crop between the last freeze in spring

and the first freeze in fall.

The average annual total precipitation is 36.84

inches. Of this, about 23.04 inches, or about 63

percent, usually falls in April through October. The

growing season for most crops falls within this period.

The heaviest 1-day rainfall during the period of record

was 13.60 inches at Joliet on July 18, 1996.

Thunderstorms occur on about 38 days each year,

and most occur between April and September.

The average seasonal snowfall is 10.2 inches. The

greatest snow depth on record was 22 inches on

December 25, 1951. On the average, 50 days per year

have at least 1 inch of snow on the ground. The

heaviest 1-day snowfall on record was 12.0 inches on

January 27, 1967.

The average relative humidity in midafternoon is

about 60 percent. Humidity is higher at night, and the

average at dawn is about 83 percent. The sun shines

67 percent of the time possible in summer and 46

percent in winter. The prevailing wind is from the south.

Average windspeed is highest, 11 to 12 miles per

hour, from November to April.

How This Survey Was Made

This survey was made to provide updated

information about the soils and miscellaneous areas in

Will County, which is a subset of Major Land Resource

Area (MLRA) 110 (fig. 1). MLRAs are geographically

associated land resource units that share a common

land use, elevation, topography, climate, pattern of

water and soils, and vegetation (USDA, 1981). Map

unit design is based on the occurrence of each soil

throughout the MLRAs.

The information in this survey includes a description

of the soils and miscellaneous areas and their

suitability, limitations, and management for specified

uses.

Soil scientists observed the steepness, length, and

shape of the slopes; the general pattern of drainage;

the kinds of crops and native plants; and the kinds of

bedrock. They prepared new soil profile descriptions

and studied many existing soil profile descriptions.

These descriptions show the sequence of natural

layers, or horizons, in a soil. The profile extends from

the surface down into the unconsolidated material in

which the soil formed. The unconsolidated material is

devoid of roots and other living organisms and has not

been changed by other biological activity.

The soils and miscellaneous areas in the survey

area occur in an orderly pattern that is related to the

geology, landforms, relief, climate, and natural

vegetation of the area. Each kind of soil and

miscellaneous area is associated with a particular kind

or segment of the landscape. By observing the soils

and miscellaneous areas in the survey area and

relating their position to specific segments of the

landscape, soil scientists develop a concept, or model,

of how the soils were formed. Thus, during the update,

this model enables the soil scientists to predict with a

considerable degree of accuracy the kind of soil or

miscellaneous area at a specific location on the

landscape.

Individual soils on the landscape commonly merge

into one another as their characteristics gradually

change. To construct an accurate map, however, soil

scientists must determine the boundaries between the

soils. They can observe only a limited number of soil

profiles. Nevertheless, these observations,

supplemented by an understanding of the soilvegetation-landscape relationship, are sufficient to

verify predictions of the kinds of soil in an area and to

determine the boundaries.

Soil scientists recorded the characteristics of the

soil profiles that they observed. The maximum depth of

observation was about 80 inches (6.7 feet). The soil

scientists noted soil color, texture, size and shape of

soil aggregates, kind and amount of rock fragments,

distribution of plant roots, soil reaction, and other

features that enable them to identify soils. After

describing the soils in the survey area and

determining their properties, the soil scientists

assigned the soils to taxonomic classes (units).

Taxonomic classes are concepts. Each taxonomic

class has a set of soil characteristics with precisely

defined limits. The classes are used as a basis for

comparison to classify soils systematically. Soil

taxonomy, the system of taxonomic classification used

in the United States, is based mainly on the kind and

character of soil properties and the arrangement of

horizons within the profile. After the soil scientists

classified and named the soils in the survey area, they

compared the individual soils with similar soils in the

same taxonomic class in other areas so that they

could confirm data and assemble additional data

based on experience and research.

While a soil survey is in progress, samples of some

of the soils in the area generally are collected for

laboratory analyses and for engineering tests. Soil
22

scientists interpret the data from these analyses and

tests as well as the field-observed characteristics and

the soil properties to determine the expected behavior

of the soils under different uses. Interpretations for all

of the soils are field tested through observation of the

soils in different uses and under different levels of

management. Interpretations are modified as

necessary to fit local conditions, and some new

interpretations are developed to meet local needs.

Data are assembled from other sources, such as

research information, production records, and field

experience of specialists. For example, data on crop

yields under defined levels of management are

assembled from farm records and from field or plot

experiments on the same kinds of soil.

Predictions about soil behavior are based not only

on soil properties but also on such variables as

climate and biological activity. Soil conditions are

predictable over long periods of time, but they are not

predictable from year to year. For example, soil

scientists can predict with a fairly high degree of

accuracy that a given soil will have a seasonal high

water table within certain depths in most years, but

they cannot predict that the water table will always be

at a specific level in the soil on a specific date. After

soil scientists located and identified the significant

natural bodies of soil in the survey area, they drew the

boundaries of these bodies on aerial photographs and

identified each as a specific map unit. Aerial

photographs show trees, buildings, fields, roads, and

rivers, all of which help in locating boundaries

accurately.
23

This section relates the soils in the survey area to

the major factors of soil formation and describes the

system of soil classification.

Formation of the Soils

Soil forms through processes that act on deposited

geologic material. The factors of soil formation are the

physical and mineralogical composition of the parent

material; the climate under which the soil formed; the

plant and animal life on and in the soil; relief; and the

length of time that the processes of soil formation have

acted on the parent material (Jenny, 1941).

Climate and plant and animal life are the dominant

active factors of soil formation. They act directly on the

parent material, slowly changing it into a natural body

that has genetically related horizons. Relief modifies

soil formation and can inhibit soil formation on the

steeper, eroded slopes and in wet depressional or

nearly level areas by controlling the moisture status of

the soils. Finally, time is needed for changing the

parent material into a soil that has differentiated

horizons.

Parent Material

Parent material is the unconsolidated geologic

material in which soils form. The soils in Will County

formed in parent materials that were directly or

indirectly impacted by Illinoian and Wisconsinan

Glaciation. The parent materials were distributed by

the action of ice, water, and wind. During the glacial

epoch, several glaciers advanced across the region

now occupied by Will County. These glaciers not only

removed old soils, but also deposited large amounts of

freshly ground-up rock materials, in which the presentday soils formed.

The glacial flooding episode that affected Will

County the most was the Kankakee Torrent. The

Kankakee Torrent was a gigantic glacial flood that

resulted from the rapid melting of three glaciers

concentrated in southern Michigan. The meltwater

then cut across northwestern Indiana and through Will

and Kankakee Counties. At its highest stage, this flood

of glacial meltwater overflowed the Kankakee Valley

and created huge glacial lakes (Lake Wauponsee,

Lake Watseka, Lake Ottawa, and Lake Pontiac), which

covered most of Iroquois County to the south, most of

Grundy County, the southern part of Kendall County,

and the western part of Will County. Many of the fine

grained lacustrine sediments in Will County were

deposited by Lake Wauponsee (Frankie, 1998).

The parent materials in Will County include till,

loess or other silty material, outwash, lacustrine

material, organic deposits, and alluvium. Some of

these materials overlie dolomitic limestone (fig. 3).

Bedrock outcrops are common along the Des Plaines

and Kankakee Rivers, particularly on the stream

bottoms and along some of the bluffs.

The unstratified till in Will County may be divided

into three general groups according to the proportions

of gravel, sand, silt, and clay. Differences in these

proportions are reflected in the texture and

permeability of the kinds of till, which, in turn, have

influenced and continue to influence soil profile

development. Many areas in the northern and eastern

parts of the county are covered with 100 to more than

150 feet of till. Till of silt loam texture is in much of the

northwest corner of the county. It is moderately

permeable or moderately slowly permeable and is

considered a more desirable parent material than till of

either coarser or finer texture. The most extensive

parent material in Will County is till of silty clay loam

texture, which is in most of the central and eastern

parts of the county. This till is moderately slowly

permeable or slowly permeable. Plant roots do not

readily penetrate more than a few inches into the

unleached till. An area of silty clay till occurs in the

northeastern part of the county. Because of the high

percentages of silt and clay, permeability is very slow

and plant roots seldom penetrate the unleached till,

except in cracks or along cleavage faces.

Loess consists mainly of silt with a little clay. It

originated from areas barren of vegetation and

exposed to wind currents that could separate the fine

particles from the coarser fragments. These areas

generally were large bottom lands and valley trains of

glacial rivers. Although some loess was undoubtedly

Formation and Classification of the Soils
24 Soil Survey of

deposited before the later glacier movements, only

that deposited on top of the last or uppermost till and

outwash is important to the modern soils. Because

loess or other silty material occurs as the surface

material, it is responsible for silt loam and silty clay

loam textures of the surface layers in about half of the

soil types in Will County.

Outwash was deposited by water flowing at different

rates down streams, across outwash plains, or into

lakes. The variation in waterflow resulted in strata that

vary in texture and thickness. Outwash thus ranges

from coarse, nearly clean gravel to very fine, nearly

pure clay. Generally, however, it is a mixture of two or

more particle sizes. Outwash covers much of the

southwestern part of the county to a depth of 10 to

more than 20 feet. Some sandy and gravelly outwash

lies beneath several feet of till in many parts of the

county. Medium textured outwash (loam and silt loam)

occurs along most of the important streams in all parts

of the county. It is excellent soil-forming material,

comparing favorably with silt loam till. Large areas of

sandy and gravelly outwash occur along the Du Page,

Des Plaines, and Kankakee Rivers, including most of

the southwest corner of the county. This is much less

desirable parent material than the outwash of loam

and silt loam. Fortunately for agriculture, a large

portion of the gravel is covered with 1 or more feet of

medium textured material. Some loamy gravel occurs

on a relatively high ridge in sections 27, 28, 29, 30,

and 31, T. 37 N., R. 10 E. (Du Page Township) and

extending into section 36, T. 37 N., R. 9 E. (Wheatland

Township).

Fine textured lacustrine, or lakebed, sediments are

in three minor areas. Two of these are in the

northeastern part of the county, one at Steger and the

other about 4 miles northeast of Frankfort. The third is

a group of small areas of Martinton and Milford soils

about 5 miles northwest of Wilmington. These latter

appear to be remnants of a former larger lakebed.

Organic deposits consist of decomposed plant

remains. After the glaciers receded, water was left

standing in depressional areas. As a result, these

areas were very wet during soil formation, and the

decaying plant material accumulated more quickly

than it decomposed. Most of these plant remains are

decomposed to a point that they are unrecognizable.

These organic deposits are called sapric material.

Houghton soils are an example of soils that formed in

these deposits.

Alluvium is material recently deposited by streams

and rivers on flood plains. The texture of alluvium

varies, depending on the velocity of the water source.

Du Page soils formed in loamy alluvium.

Areas of loamy or silty material less than 20 inches

deep over dolomitic limestone occur along the Des

Plaines River. Joliet and Romeo soils are examples of

soils that formed over bedrock.

Climate

Will County has a temperate, humid, continental

climate. The general climate has had an important

overall influence on the characteristics of the soils. It

has generally favored prairie grasses and hardwood

forests. The climate is essentially uniform throughout

the county and has not caused any major differences

among the soils.

Climate is important in soil formation because it

largely determines the type of weathering that takes

place. In most years the county has enough rainfall

and melted snowfall to moisten all soils and underlying

materials to bedrock or to the permanent water table.

Figure 3.—Glacial till over dolomite bedrock.
Will County, Illinois 25

The degree of saturation varies, depending on the

thickness and permeability of unconsolidated

materials, the water-holding capacity of these

materials, and the topography.

In general rainfall either percolates downward to

underground outlets, evaporates, is transpired by

plants, or moves across the land surface to streams,

carrying with it material in solution and suspension.

Salts of calcium, magnesium, potassium, and other

bases, as well as various organic and inorganic

colloids, are formed. Some accumulate where formed,

some are carried away in drainage waters, some are

moved to other parts of the soil, and some, in the form

of nutrient ions, are taken up by plants. The latter tend

to be returned to the local soil area unless removed by

animals or humans.

Freezing and thawing help to break down rock

fragments to smaller and smaller particles. Sunlight

and wind influence many phases of plant and animal

life.

Living Organisms

Living organisms, including all associated plant and

animal life, are responsible for the accumulation of

organic matter in soils. Two major kinds of plants, tall

prairie grasses and deciduous trees, were present

when Will County was settled and presumably had

been in the survey area for a long time. Both types of

vegetation produced large amounts of organic matter.

Forest debris, however, accumulated primarily on the

soil surface, where most of it decayed rapidly or was

burned or eroded away. A relatively small amount was

carried by soil organisms into the upper 1 to 5 inches

of mineral soil, where it is partially preserved. On the

other hand, the organic matter that accumulated from

the decaying fibrous root systems of prairie grasses is

within the mineral soil and is well preserved.

Under natural conditions, soils that formed under

both types of vegetation have a dark surface layer

because of an accumulation of organic matter. The

dark layer is much thicker in prairie soils, however,

generally ranging from 10 to 15 inches in thickness.

Varna and Elliott soils are examples of soils that

formed under prairie grasses. In soils developed under

forest, the surface layer is generally 1 to 5 inches thick.

Ozaukee and Blount soils are examples of soils that

formed under forests. Where the two types of

vegetation were combined or where forest was

encroaching onto the prairie, the soils have a dark

surface layer that is 5 to 10 inches thick. Examples are

Markham and Beecher soils. Mucky soils commonly

have an accumulation of organic matter several feet

thick.

Bacteria, fungi, and other micro-organisms help to

break down organic matter and thus provide nutrients

for plants and other soil organisms. The stability of soil

aggregates, structure units made up of sand, silt, and

clay, is affected by microbial activity, because cellular

excretions from these organisms help to bind soil

particles together. Stable aggregates help to maintain

soil porosity and promote favorable relationships

among soil, water, and air. Earthworms, crayfish,

insects, and burrowing animals tend to incorporate

organic matter into the soil and to keep soils open and

porous.

Human activities also have affected soil formation in

Will County. These include harvesting the native

vegetation, plowing the land, draining wet soils and

irrigating dry ones, applying crushed limestone to acid

soils, and applying fertilizer to areas where plant

nutrients are depleted. In sloping areas cultivation has

increased the susceptibility of the soils to erosion and

deposition. Extensive excavating, grading, and filling

have completely covered the current soil profile,

causing a new cycle of soil formation to begin.

Relief

Relief largely determines the natural drainage of

soils. Slopes in Will County range from 0 to 70 percent.

Natural soil drainage ranges from excessively drained

on back slopes and summits to very poorly drained in

depressions.

Relief affects depth to the seasonal high water table

or natural drainage of the soil by influencing infiltration

and runoff rates. The poorly drained Drummer and

Ashkum soils are in low, nearly level areas and have a

water table close to the surface for most of the year.

The soil pores contain water, which restricts the

circulation of air in the soil. Under these conditions,

iron and manganese compounds are chemically

reduced. As a result, the subsoil is dull gray and

mottled. In the more sloping, well drained Camden and

Jasper soils, the water table is lower and some of the

rainfall runs off the surface. The iron and manganese

compounds are well oxidized. As a result, the subsoil

is brownish. Between these extremes, or where the

water table fluctuates slowly into and out of the soil

profile, the compounds are moderately well oxidized to

imperfectly oxidized and colors are mixed or mottled.

Local relief influences the severity of erosion. Even

though some erosion occurs on all sloping soils, the

hazard generally is more severe in the steeper areas.
26

Runoff and the removal of soil material on these

slopes result in the formation of soils that have a

thinner solum.

In Will County drainage conditions depend primarily

on the texture and compactness of the parent material

and on the depth to drainage outlets. Relief and slope

are of some importance because they influence runoff

and depth to the water table.

Time

Time is an important factor of soil formation. The

longer soils weather, the more distinctive are their

horizons and profiles. Soil weathering and

development, however, cannot always be measured

directly in years, because other factors determine the

degree to which a soil profile develops within a given

time. Unconsolidated materials weather faster than

solid bedrock, so that a soil that formed in the former

materials will reach a certain stage of development

sooner than a soil that formed in material weathered

from bedrock. Yet, the profile of each soil becomes

more strongly weathered and developed with the

passing of time.

Classification of the Soils

The system of soil classification used by the

National Cooperative Soil Survey has six categories

(Soil Survey Staff, 1999). Beginning with the broadest,

these categories are the order, suborder, great group,

subgroup, family, and series. Classification is based on

soil properties observed in the field or inferred from

those observations or from laboratory measurements.

Table 4 shows the classification of the soils in the

county. The categories are defined in the following

paragraphs.

ORDER. Twelve soil orders are recognized. The

differences among orders reflect the dominant soilforming processes and the degree of soil formation.

Each order is identified by a word ending in sol. An

example is Mollisol.

SUBORDER. Each order is divided into suborders

primarily on the basis of properties that influence soil

genesis and are important to plant growth or

properties that reflect the most important variables

within the orders. The last syllable in the name of a

suborder indicates the order. An example is Aquoll

(Aqu, meaning water, plus oll, from Mollisol).

GREAT GROUP. Each suborder is divided into

great groups on the basis of close similarities in kind,

arrangement, and degree of development of

pedogenic horizons; soil moisture and temperature

regimes; type of saturation; and base status. Each

great group is identified by the name of a suborder

and by a prefix that indicates a property of the soil. An

example is Endoaquolls (Endo, meaning within, plus

aquoll, the suborder of the Mollisols that has an aquic

moisture regime).

SUBGROUP. Each great group has a typic

subgroup. Other subgroups are intergrades or

extragrades. The typic is the central concept of the

great group; it is not necessarily the most extensive.

Intergrades are transitions to other orders, suborders,

or great groups. Extragrades have some properties

that are not representative of the great group but do

not indicate transitions to any other known kind of soil.

Each subgroup is identified by one or more adjectives

preceding the name of the great group. The adjective

Typic identifies the subgroup that typifies the great

group. An example is Typic Endoaquolls.

FAMILY. Families are established within a

subgroup on the basis of physical and chemical

properties and other characteristics that affect

management. Generally, the properties are those of

horizons below plow depth where there is much

biological activity. Among the properties and

characteristics considered are particle-size class,

mineralogy class, cation-exchange activity class, soil

temperature regime, soil depth, and reaction class. A

family name consists of the name of a subgroup

preceded by terms that indicate soil properties. An

example is fine, mixed, superactive, mesic Typic

Endoaquolls.

SERIES. The series consists of soils that have

similar horizons in their profile. The horizons are

similar in color, texture, structure, reaction,

consistence, mineral and chemical composition, and

arrangement in the profile. The texture of the surface

layer or of the substratum can differ within a series.
27

Soil Series and Detailed Soil Map Units

In this section each soil series recognized in the

survey area is described. Each series description is

followed by detailed descriptions of the associated

detailed soil map units.

Characteristics of the soil and the material in which

it formed are identified for each soil series. A pedon, a

small three-dimensional area of soil, that is typical of

the series in the survey area is described. The detailed

description of each soil horizon follows standards in

the “Soil Survey Manual” (Soil Survey Division Staff,

1993). Many of the technical terms used in the

descriptions are defined in “Soil Taxonomy” (Soil

Survey Staff, 1999) and in “Keys to Soil Taxonomy”

(Soil Survey Staff, 1998). Unless otherwise stated,

colors in the descriptions are for moist soil. Following

the pedon description is the range of important

characteristics of the soils in the series.

The map units on the detailed soil maps in this

survey represent the soils or miscellaneous areas in

the survey area. The map unit descriptions in this

section, along with the maps, can be used to

determine the suitability and potential of a unit for

specific uses. They also can be used to plan the

management needed for those uses. More information

about each map unit is given under the headings “Use

and Management of the Soils” and “Soil Properties.”

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.

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. The contrasting

components are mentioned in the map unit

descriptions. 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 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 the principal

hazards and limitations affecting specific uses.

Soils that have profiles that are almost alike make

up a soil series. Except for differences in texture of the

surface layer or of the underlying layers, 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 or of the underlying layers. They also can

differ in slope, stoniness, salinity, wetness, degree of

erosion, and other characteristics that affect their use.

On the basis of such differences, a soil series is

divided into soil phases. The name of a soil phase
28 Soil Survey of

commonly indicates a feature that affects use or

management. For example, Varna silt loam, 4 to 6

percent slopes, eroded, is a phase of the Varna series.

Some map units are made up of two or more major

soils or miscellaneous areas. These map units are

complexes and undifferentiated groups. A complex

consists of two or more soils 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 are somewhat similar in all

areas. Casco-Rodman complex, 20 to 30 percent

slopes, is an example. An undifferentiated group is

made up of two or more soils that could be mapped

individually but are mapped as one unit because

similar interpretations can be made for use and

management. Muskego and Houghton mucks, 0 to 2

percent slopes, is an example. The pattern and

proportion of the soils in a mapped area are not

uniform. An area can be made up of only one of the

major soils, or it can be made up of all of them.

This survey includes miscellaneous areas. Such

areas have little or no soil material and support little or

no vegetation. Pits, gravel, is an example.

Table 5 gives the acreage and proportionate extent

of each map unit. Other tables give properties of the

soils and the limitations, capabilities, and potentials for

many uses. The Glossary defines many of the terms

used in describing the soils or miscellaneous areas.

This soil survey is an inventory and evaluation of

the soils in the survey area. It can be used to adjust

land uses to the limitations and potentials of natural

resources and the environment. Also, it can help to

prevent soil-related failures in land uses.

In preparing a soil survey, soil scientists,

conservationists, engineers, and others collect

extensive field data about the nature and behavioral

characteristics of the soils. They collect data on

erosion, droughtiness, flooding, and other factors that

affect various soil uses and management. Field

experience and collected data on soil properties and

performance are used as a basis in predicting soil

behavior.

Information in this section can be used to plan the

use and management of soils for crops and pasture;

as forestland; as sites for buildings, sanitary facilities,

highways and other transportation systems, and parks

and other recreational facilities; for agricultural waste

management; and as wildlife habitat. It can be used to

identify the potentials and limitations of each soil for

specific land uses and to help prevent construction

failures caused by unfavorable soil properties.

Planners and others using soil survey information

can evaluate the effect of specific land uses on

productivity and on the environment in all or part of the

survey area. The survey can help planners to maintain

or create a land use pattern in harmony with the

natural soil.

Contractors can use this survey to locate sources

of sand, gravel, reclamation material, roadfill, and

topsoil. They can use it to identify areas where

bedrock, wetness, or very firm soil layers can cause

difficulty in excavation.

Health officials, highway officials, engineers, and

others may also find this survey useful. The survey

can help them plan the safe disposal of wastes and

locate sites for pavements, sidewalks, campgrounds,

playgrounds, lawns, and trees and shrubs.

Interpretive Ratings

The interpretive tables in this survey rate the

soils in the survey area for various uses. Many of

the tables identify the limitations that affect specified

uses and indicate the severity of those limitations.

The ratings in these tables are both verbal and

numerical.

Rating Class Terms

Rating classes are expressed in the tables in terms

that indicate the extent to which the soils are limited by

all of the soil features that affect a specified use or in

terms that indicate the suitability of the soils for the

use. Thus, the tables may show limitation classes or

suitability classes. Terms for the limitation classes are

not limited, somewhat limited, and very limited. The

suitability ratings are expressed as well suited,

moderately suited, poorly suited, and unsuited or as

good, fair, and poor.

Numerical Ratings

Numerical ratings in the tables indicate the relative

severity of individual limitations. The ratings are shown

as decimal fractions ranging from 0.00 to 1.00. They

indicate gradations between the point at which a soil

feature has the greatest negative impact on the use

and the point at which the soil feature is not a

limitation. The limitations appear in order from the

most limiting to the least limiting. Thus, if more than

one limitation is identified, the most severe limitation is

listed first and the least severe one is listed last.

Crops and Pasture

General management needed for crops and pasture

is suggested in this section. The estimated yields of

the main crops and pasture plants are listed, the

system of land capability classification used by the

Natural Resources Conservation Service is explained,

and prime farmland is described.

Planners of management systems for individual

fields or farms should consider the detailed

information given in the description of each soil under

the heading “Soil Series and Detailed Soil Map Units.”

Specific information can be obtained from the local

office of the Natural Resources Conservation Service

or the Cooperative Extension Service.

Use and Management of the Soils
182 Soil Survey of

In 2002, Will County had 250,590 acres of cropland

(USDA, Farm Service Agency, 2002). The major row

crops are corn and soybeans. The major small grain

crop is wheat. Alfalfa is the major forage crop. Some

areas are used for vegetable or nursery crops.

The soils in Will County have good potential for

continued crop production, especially if the latest cropproduction technology is applied. This soil survey can

be used as a guide in applying this technology.

Water erosion is a potential problem on

approximately 56 percent of the cropland in the county.

Erosion can be a problem on soils with slopes of more

than 2 percent, such as Beecher, Elliott, and Frankfort

soils. It also is a hazard in areas where slopes are less

than 2 percent but are long and runoff water is

concentrated.

Loss of the surface layer through sheet and rill

erosion is damaging for several reasons. Soil

productivity is reduced as the surface soil is removed

and part of the subsoil is incorporated into the plow

layer. The subsoil is generally lower in content of plant

nutrients and organic matter and higher in content of

clay than the surface soil. As the amount of organic

matter decreases and the content of clay increases in

the plow layer, soil tilth deteriorates, resulting in soil

crusting and a reduced rate of water intake. Under

these conditions, preparing a good seedbed could be

difficult. Erosion results in the sedimentation of

streams, rivers, road ditches, and lakes. Sediment

pollution reduces water quality for agricultural,

municipal, and recreational uses and for fish and

wildlife. Removing the sediment generally is expensive.

Erosion control helps to minimize this pollution and

improves water quality.

Erosion-control measures include both cultural and

structural practices. The most widely used cultural

practice in the county is conservation tillage, such as

chisel plowing, no-till farming, or ridge planting. These

systems leave a cover of crop residue on 20 to 90

percent of the surface. No-till farming is most effective

on well drained and moderately well drained soils,

such as Jasper and Varna soils. Another cultural

practice is a crop rotation that includes 1 or more

years of close-growing grasses or legumes. If slopes

are smooth and uniform, terraces and contour farming

also are effective in controlling erosion.

Structural practices are needed in drainageways

where concentrated runoff flows overland. Establishing

grassed waterways or constructing erosion-control

structures reduces the hazard of erosion.

Further information about the erosion-control

measures suitable for each kind of soil is provided in

the Field Office Technical Guide, which is available in

local offices of the Natural Resources Conservation

Service.

Soil tilth is an important factor influencing the

germination of seeds, the amount of runoff, and the

rate of water infiltration. Soils that have good tilth are

granular and porous and have a high content of

organic matter.

Poor tilth is a problem on soils that have a surface

layer of silty clay loam or silty clay. If such soils as

Ashkum, Bryce, and Pella soils are plowed when wet,

their surface layer becomes cloddy. This cloddiness

hinders the preparation of a good seedbed. Tilling in

the fall, leaving the soil surface rough, and leaving

moderate amounts of crop residue on the surface

generally result in good tilth in the spring. A system of

strip or ridge tillage may also work well on these soils.

Crusting can be a problem in areas of Camden and

Nappanee soils, which have a surface layer of silt

loam that is low in content of organic matter. Generally,

the structure of these soils is weak, and a crust forms

on the surface during periods of intense rainfall. This

crust is hard when dry. It inhibits seedling emergence,

reduces the infiltration rate, and increases the runoff

rate and the hazard of erosion. Regular additions of

crop residue, manure, and other organic material

improve soil structure and minimize crusting.

Drainage systems have been installed in most

areas of the poorly drained and somewhat poorly

drained soils used as cropland in the county.

Therefore, these soils are adequately drained for the

crops commonly grown in the county. Measures that

maintain the drainage system are needed. A

subsurface drainage system has been installed in

poorly drained soils, such as, Drummer, Elpaso, and

Selma soils. Some areas of poorly drained and very

poorly drained soils, such as Bryce, Peotone, and

Rantoul soils, require surface tile inlets or shallow

surface ditches to remove excess water. In some

areas somewhat poorly drained soils are wet long

enough for productivity to be reduced in some years

unless a drainage system is installed. A subsurface

drainage system has been installed in the somewhat

poorly drained Blount, Elliott, and Swygert soils.

Contamination of ground water is a hazard in areas

of excessively permeable soils, such as Waupecan

and Dresden soils. These soils have sandy and

gravelly deposits within a depth of 60 inches and are

very rapidly permeable in the lower part.

Several measures help to prevent deep leaching of

nutrients and pesticides. Applications of fertilizer

should be based on the results of soil tests. The local

office of the Cooperative Extension Service can help

in determining the kinds and amounts of nutrients
Will County, Illinois 183

needed. Chemicals should be selected on the basis of

their solubility in water, their ability to bind with the soil,

and the rate of their breakdown in the soil. Splitting

chemical applications, particularly nitrogen, is

beneficial. This practice reduces the chance for

excessive leaching, which can result from a one-time

application. Another measure is planting legumes in a

crop rotation or as a cover crop. The legumes add

nitrogen to the soil, thereby reducing the amount of

nitrogen needed in chemical applications. Crop

rotations are effective in limiting the buildup of weed

and insect populations. Limiting this buildup, in turn,

reduces the amount of herbicides and insecticides

needed per application. Growing small grain cover

crops after fertilized corn is grown can be effective in

taking up some residual nitrogen from the soil.

Restricted permeability can increase the

susceptibility of a soil to erosion. As water movement

slows within a soil, the hazard of runoff increases. The

slowly permeable Frankfort soils are more susceptible

to erosion than the moderately permeable Jasper

soils. The effect that restricted permeability has on the

erosion hazard can be reduced by applying a cropping

system that leaves crop residue on the surface after

planting, by incorporating green manure crops or crop

residue into the soil, and by using conservation

cropping systems.

Restricted permeability can limit the effectiveness

of drainage systems. To be effective in lowering the

seasonal high water table, tile must be more closely

spaced in the slowly permeable Elliott soils than in the

moderately permeable Brenton soils.

A root-restrictive layer limits the available water

capacity of soils. Frankfort, Varna, and Swygert soils

are moderately deep to layers that restrict the

penetration of plant roots. Increasing the rate of water

infiltration, reducing the runoff rate, or planting

drought-tolerant species can minimize the effect of this

limitation. Planting cover crops and applying a system

of conservation tillage that leaves crop residue on the

surface after planting increase the rate of water

infiltration and reduce the runoff rate. Planting droughttolerant species, such as soybeans and winter wheat,

is beneficial because these crops make the most

efficient use of the limited amount of water.

Proper management is needed on hayland to

prolong the life of desirable forage species, maintain or

improve the quality and quantity of forage, and control

erosion and runoff. Hay may last as a vigorous crop for

4 to 5 years, depending on management and on the

varieties seeded. Suitable hay plants include several

legumes and cool-season grasses. Alfalfa is the most

common legume grown for hay. It is often grown in

mixtures with smooth bromegrass and orchardgrass.

Alfalfa is best suited to moderately well drained soils,

such as Graymont and Symerton soils. Red clover

also is grown for hay. Measures that maintain or

improve fertility are needed. The amount of lime and

fertilizer to be added to the soil should be based on

the results of soil tests, the needs of the plants, and

the expected level of yields. Seed varieties should be

selected in accordance with the soil properties and the

drainage conditions of the tract of land.

Overgrazing reduces the vigor of pasture plants

and reduces forage production. It also increases the

extent of weeds and brush. Deferred grazing, rotation

grazing, and proper stocking rates help to prevent

overgrazing. Deferred grazing allows the plants in

pastures that are not being used to build up reserves

of carbohydrates. Rotating grazing among several

pastures allows each area a rest period.

Many of the soils in the survey area have a high

water table in spring. Deferred grazing during wet

periods can minimize surface compaction. Pasture

renovation also helps to prevent compaction. Frost

heave can damage alfalfa and red clover in areas that

have a seasonal high water table. Leaving a cover of

stubble 4 to 6 inches high during the winter and

planting mixtures of grasses and legumes help to

prevent frost heave.

Management Considerations on Cropland

The management concerns affecting the use of the

soils in Will County for crops and pasture are shown in

the table 6. The main concerns in managing

nonirrigated cropland are water erosion, crusting, poor

tilth, wetness, ponding, excessive permeability,

restricted permeability, depth to bedrock, and a rootrestrictive layer. Excess lime, flooding, a limited

available water capacity, and wind erosion are

additional management concerns.

Generally, a combination of several practices is

needed to control water erosion. Conservation tillage,

stripcropping, field windbreaks, contour farming,

conservation cropping systems, crop residue

management, terraces, diversions, grassed filter

strips, and grassed waterways help to prevent

excessive soil loss.

Measures that minimize crusting and improve poor

tilth include incorporating green manure crops,

manure, or crop residue into the soil and applying a

system of conservation tillage. Avoiding tillage when

the soil is too wet can minimize surface cloddiness.

In some areas of cropland, wetness is a limitation

and ponding is a hazard. Drainage systems consist of
184 Soil Survey of

subsurface tile drains, surface inlet tile, open drainage

ditches, or a combination of these. Measures that

maintain the drainage system are needed.

Excessive permeability can cause deep leaching of

nutrients and pesticides. Selecting appropriate

chemicals and using split application methods reduce

the hazard of ground-water contamination.

Restricted permeability can increase the

susceptibility of the soil to erosion and limit the

effectiveness of drainage systems. The hazard of

erosion can be reduced by incorporating green

manure crops, manure, or crop residue into the soil

and by applying conservation tillage and conservation

cropping systems. Narrowing the spacing of tile

improves the ability of the drainage system to lower

the seasonal high water table.

Bedrock within a depth of 10 inches can limit the

rooting depth and the amount of available moisture in

the soil. This limitation cannot be easily overcome.

Applying conservation tillage and conservation

cropping systems and leaving crop residue on the

surface conserve moisture.

A root-restrictive layer in a soil limits the total

amount of water available to plants. Planting cover

crops and applying a system of conservation tillage

that leaves crop residue on the surface after planting

increase the rate of water infiltration and reduce the

runoff rate. Also, planting drought-tolerant crop

species makes the most efficient use of the limited

supply of available water in the soil.

Excess lime can be overcome by incorporating

green manure crops, manure, or crop residue into the

soil and by applying conservation tillage and

conservation cropping systems. Also, crops may

respond well to additions of phosphate fertilizer on

soils that have a high content of lime.

Flooding cannot be easily overcome. Winter small

grains can be damaged by floodwater. Tilling and

planting should be delayed in the spring until flooding

is no longer a hazard. Dikes and diversions can

reduce the extent of the crop damage caused by

floodwater.

The effects of a limited available water capacity can

be minimized by reducing the evaporation and runoff

rates and increasing the water intake rate. Applying

conservation tillage and conservation cropping

systems, farming on the contour, stripcropping,

establishing field windbreaks, and leaving crop residue

on the surface conserve moisture.

Wind erosion can be controlled by applying a

system of conservation tillage that leaves crop residue

on the surface after planting and keeping the surface

rough.

Explanation of Criteria

Crusting.—In the surface layer, the average content

of organic matter is 2.5 percent or less and the content

of clay is between 20 and 35 percent.

Depth to bedrock.—Bedrock is within 10 inches of

the surface.

Excess lime.—A calcium carbonate equivalent of 15

percent or more is within a depth of 16 inches.

Excessive permeability.—The lower limit of the

permeability rate is 6.0 or more inches per hour within

the soil profile.

Flooding.—The soil is occasionally flooded or

frequently flooded.

Limited available water capacity.—The weighted

average of the available water capacity between

depths of 0 and 40 inches is 0.1 inch or less.

Ponding.—The seasonal high water table is above

the surface.

Poor tilth.—The content of clay in the surface layer

is 27 percent or more.

Water erosion.—The Kw factor of the surface layer

multiplied by the slope is more than 0.8, and the slope

is 3 percent or more.

Wetness.—The seasonal high water table is within

a depth of 1.5 feet.

Management Considerations on Pasture

The management concerns affecting the use of the

soils in the county for pasture are shown in the table 6.

The main management concerns are frost heave,

water erosion, wetness, ponding, low pH, a rootrestrictive layer, a limited available water capacity, an

equipment limitation, flooding, wind erosion, depth to

bedrock, excess lime, low fertility, and rock fragments

on the surface.

Frost heave is a limitation in soils that have a

moderate or high potential for frost action. It occurs

when ice lenses or bands that drive an ice wedge

between two layers develop near the surface layer of a

soil. The ice wedges heave the overlying soil layer

upward, snapping the roots. Soils with a low content of

sand have small pores that hold water and enable ice

lenses to form. Selecting adapted forage and hay

varieties helps to reduce the effects of frost heave.

Timely deferment of grazing helps to maintain a

protective cover that insulates the soil, thereby

reducing the effects of frost heave.

Water erosion is a hazard in pastured areas where

the value of the Kw factor multiplied by the slope is 0.8

or more and the slope is 3 percent or more. Water

erosion reduces the productivity of pasture. It also
Will County, Illinois 185

results in onsite and offsite sedimentation, causes

water pollution by sedimentation, and increases the

runoff of livestock manure and other nutrients.

Establishing or renovating stands of legumes and

grasses helps to control erosion. Controlling erosion

during seedbed preparation is a major concern. If the

soil is tilled for the reseeding of pasture or hay crops,

planting winter cover crops, establishing grassed

waterways, farming on the contour, and applying a

system of conservation tillage that leaves crop residue

on the surface can help to minimize erosion.

Overgrazing or grazing when the soil is wet reduces

the extent of the plant cover, results in surface

compaction and poor tilth, and thus increases the

susceptibility to erosion. Proper stocking rates, rotation

grazing, and timely deferment of grazing, especially

during wet periods, help to keep the pasture in good

condition. Properly locating livestock watering facilities

helps to prevent surface compaction or the formation

of ruts by making it unnecessary for cattle to travel

long distances up and down the steeper slopes.

Wetness and ponding are management concerns in

some areas of pasture or hayland. Wetness occurs

when the seasonal high water table is within 1.5 feet of

the surface, and ponding occurs when the seasonal

high water table is above the surface. Drainage

systems consisting of subsurface tile drains, surface

inlet tile, open drainage ditches, or a combination of

these help to lower the water table and remove excess

water. Measures that maintain the drainage system

are needed. Selecting species of grasses and

legumes adapted to wet conditions improves forage

production. Restricted use during wet periods helps to

keep the pasture in good condition.

Soils that have low pH or low reaction have a pH

value of 5.5 or less within 40 inches of the surface.

Low pH inhibits the uptake of certain nutrients by the

plants or accelerates the absorption of certain other

elements to the level of toxic concentrations. Either of

these conditions affects the health and vigor of the

plants. Applications of lime should be based on the

results of soil tests. The goal is to achieve the optimum

pH level for the uptake of the major nutrients by the

specific grass, legume, or combination of grasses and

legumes.

Soils that have a root-restrictive layer have a dense

layer of till within 40 inches of the surface. This layer

inhibits root penetration. This limitation lowers the total

amount of water that is available to plants. Deeprooted perennial legumes and grasses make the most

efficient use of the limited amount of available water.

Selecting drought-tolerant species of legumes and

grasses improves forage production.

Limited available water capacity occurs in areas

where the weighted average of the available water

capacity between depths of 0 and 40 inches is 0.1

inch or less. Available water capacity refers to the

capacity of soils to hold water available for use by

most plants. The quality and quantity of the pasture

plants may be reduced if the amount of available water

is inadequate for maintenance of a healthy community

of desired pasture species. The pasture cannot

support the desired number of livestock. A poor-quality

pasture may increase the hazard of water erosion and

increase the runoff of pollutants. Planting droughtresistant species of grasses and legumes helps to

establish a cover of vegetation. The plants should not

be clipped or grazed until they are sufficiently

established.

An equipment limitation occurs in areas where

slopes are more than 10 percent. It can cause rapid

wear of equipment and can hinder fertilization,

harvest, pasture renovation, and seedbed preparation.

This limitation cannot be easily overcome.

Frequent flooding can damage forage stands and

delay harvesting in some years. Dikes and diversions

help to control the extent of damage caused by

floodwater. Selecting species of grasses and legumes

adapted to wet conditions improves forage production.

Restricted grazing during wet periods helps to keep

the pasture in good condition.

Organic and sandy soils that have a wind erodibility

group (WEG) of 1 or 2 are susceptible to wind erosion.

If the soil is tilled for the reseeding of pasture or hay

crops, planting winter cover crops, applying a system

of conservation tillage that leaves crop residue on the

surface, and keeping the surface rough help to control

wind erosion. Overgrazing or grazing when the soil is

wet reduces the extent of the plant cover and thus

increases the susceptibility to wind erosion. Proper

stocking rates, rotation grazing, and timely deferment

of grazing, especially during wet periods, help to keep

the pasture in good condition.

Soils in which the depth to bedrock is 30 inches or

less have a restricted root zone and a limited amount

of available moisture. Planting adapted forage and hay

varieties minimizes this limitation. The plants should

not be clipped or grazed until they are sufficiently

established. Rotation grazing and timely deferment of

grazing help to maintain healthy stands of forage

plants, which, in turn, reduce the runoff rate and thus

conserve moisture.

Excess lime occurs in soils that have a calcium

carbonate equivalent of 15 percent or more within 16

inches of the surface. The high pH associated with this

limitation can inhibit the uptake of certain nutrients and

micronutrients by the plants or accelerates the

absorption of certain other elements to the level of
186 Soil Survey of

toxic concentrations. Either of these conditions affects

the health and vigor of the plants. Applications of

sulfate and phosphate compounds or additions of

certain forms of nitrogen fertilizer help to lower the pH.

Selecting species of grasses and legumes that are

tolerant of high pH improves forage production.

Low fertility occurs in areas where the average

content of organic matter in the surface layer is less

than 1 percent or the cation-exchange capacity (CEC)

is 7 milliequivalents or less per 100 grams of soil. Low

fertility affects the health and vigor of the plants and

thus has a direct impact on the quantity and quality of

livestock. Additions of fertilizer and other organic

material should be based on the results of soil tests,

on the needs of specific plant species, and on the

desired level of production.

In areas where rock fragments cover more than 15

percent of the surface, seedbed preparation and

renovation may be hindered. This limitation causes

rapid wear of tillage equipment. It cannot be easily

overcome. The cobbles and stones can be removed or

piled in a corner of the field.

Yields per Acre

The average yields per acre that can be expected

of the principal crops under a high level of

management are shown in table 7. In any given year,

yields may be higher or lower than those indicated in

the table because of variations in rainfall and other

climatic factors. The land capability classification of

map units in the survey area also is shown in the

table.

The yields are based mainly on the experience and

records of farmers, conservationists, and extension

agents. Available yield data from nearby counties and

results of field trials and demonstrations also are

considered (Fehrenbacher and others, 1978).

The management needed to obtain the indicated

yields of the various crops depends on the kind of soil

and the crop. Management can include drainage,

erosion control, and protection from flooding; the

proper planting and seeding rates; suitable highyielding crop varieties; appropriate and timely tillage;

control of weeds, plant diseases, and harmful insects;

favorable soil reaction and optimum levels of nitrogen,

phosphorus, potassium, and trace elements for each

crop; effective use of crop residue, barnyard manure,

and green manure crops; and harvesting that ensures

the smallest possible loss.

The estimated yields reflect the productive capacity

of each soil for each of the principal crops. Yields are

likely to increase as new production technology is

developed. The productivity of a given soil compared

with that of other soils, however, is not likely to

change.

Crops other than those shown in table 7 are grown

in the survey area, but estimated yields are not listed

because the acreage of such crops is small. The local

office of the Natural Resources Conservation Service

or of the Cooperative Extension Service can provide

information about the management and productivity of

the soils for those crops.

Pasture and Hay Yields

Soils are assigned to pasture and hayland groups

according to their suitability for the production of

forage. The soils in each group are similar enough to

be suited to the same species of grasses or legumes,

have similar limitations and hazards, require similar

management, and have similar productivity levels and

other responses to management.

Under good management, proper grazing is

essential for the production of high-quality forage,

stand survival, and erosion control. Proper grazing

helps the plants to maintain sufficient and generally

vigorous top growth during the growing season. Brush

control is essential in many areas, and weed control

generally is needed. Rotation grazing and renovation

also are important management practices.

Yield estimates are often given in animal unit

months (AUMs), or the amount of forage or feed

required to feed one animal unit (one cow, one horse,

one mule, five sheep, or five goats) for 30 days.

The local office of the Natural Resources

Conservation Service or of the Cooperative Extension

Service can provide information about forage yields

other than those shown in table 7.

Land Capability Classification

Land capability classification shows, in a general

way, the suitability of soils for most kinds of field crops,

including corn, small grain, and hay. Crops that require

special management are excluded. The soils are

grouped according to their limitations for field crops,

the risk of damage if they are used for crops, and the

way they respond to management. The criteria used in

grouping the soils do not include major and generally

expensive landforming that would change slope,

depth, or other characteristics of the soils, nor do they

include possible but unlikely major reclamation

projects. Capability classification is not a substitute for

interpretations designed to show suitability and

limitations of groups of soils for woodland or for

engineering purposes.

In the capability system, soils are generally grouped

at three levels—capability class, subclass, and unit
Will County, Illinois 187

(USDA, 1961). Only class and subclass are used in

this survey.

Capability classes, the broadest groups, are

designated by the numbers 1 through 8. The numbers

indicate progressively greater limitations and narrower

choices for practical use. The classes are defined as

follows:

Class 1 soils have slight limitations that restrict their

use.

Class 2 soils have moderate limitations that restrict

the choice of plants or that require moderate

conservation practices.

Class 3 soils have severe limitations that restrict the

choice of plants or that require special conservation

practices, or both.

Class 4 soils have very severe limitations that

restrict the choice of plants or that require very careful

management, or both.

Class 5 soils are subject to little or no erosion but

have other limitations, impractical to remove, that

restrict their use mainly to pasture, rangeland,

forestland, or wildlife habitat.

Class 6 soils have severe limitations that make

them generally unsuitable for cultivation and that

restrict their use mainly to pasture, rangeland,

forestland, or wildlife habitat.

Class 7 soils have very severe limitations that

make them unsuitable for cultivation and that restrict

their use mainly to grazing, forestland, or wildlife

habitat.

Class 8 soils and miscellaneous areas have

limitations that preclude commercial plant production

and that restrict their use to recreational purposes,

wildlife habitat, watershed, or esthetic purposes.

Capability subclasses are soil groups within one

class. They are designated by adding a small letter, e,

w, s, or c, to the class numeral, for example, 2e. The

letter e shows that the main hazard is the risk of

erosion unless close-growing plant cover is

maintained; w shows that water in or on the soil

interferes with plant growth or cultivation (in some soils

the wetness can be partly corrected by artificial

drainage); s shows that the soil is limited mainly

because it is shallow, droughty, or stony; and c, used

in only some parts of the United States, shows that the

chief limitation is climate that is very cold or very dry.

In class 1 there are no subclasses because the

soils of this class have few limitations. Class 5

contains only the subclasses indicated by w, s, or c

because the soils in class 5 are subject to little or no

erosion. They have other limitations that restrict their

use to pasture, rangeland, forestland, wildlife habitat,

or recreation.

The capability classification of map units in this

survey area is given in the section “Soil Series and 

Detailed Soil Map Units” and in table 7.

Prime Farmland

Prime farmland is one of several kinds of important

farmland defined by the U.S. Department of

Agriculture. It is of major importance in meeting the

Nation’s short- and long-range needs for food and

fiber. Because the supply of high-quality farmland is

limited, the U.S. Department of Agriculture recognizes

that responsible levels of government, as well as

individuals, should encourage and facilitate the wise

use of our Nation’s prime farmland.

Prime farmland, as defined by the U.S. Department

of Agriculture, is land that has the best combination of

physical and chemical characteristics for producing

food, feed, forage, fiber, and oilseed crops and is

available for these uses. It could be cultivated land,

pastureland, forestland, or other land, but it is not

urban or built-up land or water areas. The soil qualities,

growing season, and moisture supply are those

needed for the soil to economically produce sustained

high yields of crops when proper management,

including water management, and acceptable farming

methods are applied. In general, prime farmland has

an adequate and dependable supply of moisture from

precipitation or irrigation, a favorable temperature and

growing season, acceptable acidity or alkalinity, an

acceptable salt and sodium content, and few or no

rocks. It is permeable to water and air. It is not

excessively erodible or saturated with water for long

periods, and it either is not frequently flooded during

the growing season or is protected from flooding.

Slope ranges mainly from 0 to 6 percent. More

detailed information about the criteria for prime

farmland is available at the local office of the Natural

Resources Conservation Service.

In the last two decades, a trend in land use in some

parts of the survey area has been the loss of some

prime farmland to industrial and urban uses. The loss

of prime farmland to other uses puts pressure on

marginal lands, which generally are more erodible,

droughty, and less productive and cannot be easily

cultivated.

About 404,640 acres, or nearly 75 percent of the

county, meets the requirements for prime farmland.

The map units in the county that are considered

prime farmland are listed in table 8. This list does not

constitute a recommendation for a particular land use.

On some soils included in the list, measures that

overcome a hazard or limitation, such as flooding and
188 Soil Survey of

wetness, are needed. Onsite evaluation is needed to

determine whether or not the hazard or limitation has

been overcome by corrective measures. The extent of

each listed map unit is shown in table 5. The location

is shown on the detailed soil maps. The soil qualities

that affect use and management are described under

the heading “Soil Series and Detailed Soil Map Units.”

Hydric Soils

In this section, hydric soils are defined and

described and the hydric soils in the survey area are

listed.

The three essential characteristics of wetlands are

hydrophytic vegetation, hydric soils, and wetland

hydrology (Cowardin and others, 1979; U.S. Army

Corps of Engineers, 1987; National Research Council,

1995; Tiner, 1985). Criteria for each of the

characteristics must be met for areas to be identified

as wetlands. Undrained hydric soils that have natural

vegetation should support a dominant population of

ecological wetland plant species. Hydric soils that

have been converted to other uses should be capable

of being restored to wetlands.

Hydric soils are defined by the National Technical

Committee for Hydric Soils (NTCHS) as soils that

formed under conditions of saturation, flooding, or

ponding long enough during the growing season to

develop anaerobic conditions in the upper part

(Federal Register, 1994). These soils are either

saturated or inundated long enough during the

growing season to support the growth and

reproduction of hydrophytic vegetation.

The NTCHS definition identifies general soil

properties that are associated with wetness. In order

to determine whether a specific soil is a hydric soil or

nonhydric soil, however, more specific information,

such as information about the depth and duration of

the water table, is needed. Thus, criteria that identify

those estimated soil properties unique to hydric soils

have been established (Federal Register, 1995). These

criteria are used to identify a phase of a soil series

that normally is associated with wetlands. The criteria

used are selected estimated soil properties that are

described in “Soil Taxonomy” (Soil Survey Staff, 1999)

and in the “Soil Survey Manual” (Soil Survey Division

Staff, 1993).

If soils are wet enough for a long enough period to

be considered hydric, they should exhibit certain

properties that can be easily observed in the field.

These visible properties are indicators of hydric soils.

The indicators used to make onsite determinations of

hydric soils in this survey area are specified in “Field

Indicators of Hydric Soils in the United States” (Hurt

and others, 1998).

Hydric soils are identified by examining and

describing the soil to a depth of about 20 inches. This

depth may be greater if determination of an

appropriate indicator so requires. It is always

recommended that soils be excavated and described

to the depth necessary for an understanding of the

redoximorphic processes. Then, using the completed

soil descriptions, soil scientists can compare the soil

features required by each indicator and specify which

indicators have been matched with the conditions

observed in the soil. The soil can be identified as a

hydric soil if at least one of the approved indicators is

present.

Map units that are made up mainly of hydric soils

may have small areas, or inclusions, of nonhydric soils

in the higher positions on the landform, and map units

made up mainly of nonhydric soils may have

inclusions of hydric soils in the lower positions on the

landform. Table 9 indicates the hydric and nonhydric

soils identified in the names of the detailed map units

in the county. The table also identifies the included

soils that are considered hydric. Onsite investigation is

recommended to determine whether hydric soils occur

and the location of the included hydric soils.

Windbreaks and Environmental

Plantings

Windbreaks protect livestock, buildings, yards, fruit

trees, gardens, and cropland from wind and snow;

help to keep snow on fields; and provide food and

cover for wildlife. Several rows of low- and highgrowing broadleaf and coniferous trees and shrubs

provide the most protection.

Field windbreaks are narrow plantings made at right

angles to the prevailing wind and at specific intervals

across the field. The interval depends on the erodibility

of the soil.

Environmental plantings help to beautify and screen

houses and other buildings and to abate noise. The

plants, mostly evergreen shrubs and trees, are closely

spaced. To ensure plant survival, a healthy planting

stock of suitable species should be planted properly

on a well prepared site and maintained in good

condition.

Windbreaks are often planted on land that did not

originally support trees. Knowledge of how trees

perform on such land can be gained only by observing

and recording the performance of trees that have been

planted and have survived. Many popular windbreak
Will County, Illinois 189

species are not indigenous to the areas in which they

are planted.

Each tree or shrub species has certain climatic and

physiographic limits. Within these parameters, a tree

or shrub may grow well or grow poorly, depending on

the characteristics of the soil. Each tree or shrub has

definable potential heights in a given physiographic

area and under a given climate. Accurate definitions of

the potential heights are necessary when a windbreak

is planned and designed.

Table 10 shows the height that locally grown trees

and shrubs are expected to reach in 20 years on

various soils. The estimates in table 10 are based on

measurements and observation of established

plantings that have been given adequate care. They

can be used as a guide in planning windbreaks and

screens. Additional information on planning

windbreaks and screens and planting and caring for

trees and shrubs can be obtained from the local office

of the Natural Resources Conservation Service or of

the Cooperative Extension Service or from a

commercial nursery.

Forestland

Paul M. Deizman, district forester, Illinois Department of Natural

Resources, helped prepare this section.

Forest once covered nearly 13 percent of the land

in Will County. Little of the presettlement forestland has

been untouched or properly managed. Presently,

about 30,000 acres, or 5.5 percent of the total land

area in the county, is forested. An 9,200 additional

acres, or about 2 percent of the total land area, is

considered new tree-covered land or brushland.

Over the past century new forests have been

created only by natural succession of fallow upland

and bottom-land areas, by abandonment of lowyielding cropland, and by seeding or planting of

seedlings. Only 10 percent of the present forestland is

under proper timber management. Areas of grazed

forestland are slowly recovering but may require many

decades or a full forest generation in order to become

productive without management.

The principal forest types in Will County are oakhickory (12,000 acres), maple-beech (11,500 acres),

elm-ash-soft maple (4,800 acres), and cottonwood

(1,000 acres). At least 88 different tree species and 92

shrub species are evident in the county.

Two sawmills operate within the borders of Will

County. The number of sawmills has been gradually

declining. The sawmills in and around the county

borders adequately meet the local needs for custom

sawing. Nearly a dozen small, portable mills are in the

county or serve county landowners. The current

hardwood markets are globally oriented. Any owner

with quality forest products has reasonable access to

commercial markets through interested buyers, forest

operators, State foresters, and forestry consultants

within this part of the Midwest. The demand for

standing timber from Will County is moderate. At last

count, 38 firms, employing nearly 19,000 individuals,

manufacture or use wood products and paper

products in Will County. These include primarily

millwork, container and pallet, building material,

furniture, and paper firms.

Will County has tremendous potential for

establishing additional productive forestland. The

highly erodible land (HEL) in the county includes

nearly 43,100 acres that would be especially well

suited to hardwood forest. Forestry in Will County not

only is potentially profitable but also serves to enhance

watershed quality, recreational uses, and wildlife

habitat. Interest in forest management and

establishment in the county is moderate. The average

forest holding per landowner is 12.9 acres. Even

parcels as small as 5 acres can be effectively

managed for both timber production and multipleresource conservation.

Assistance in establishing, improving, or managing

forestland is available from foresters or natural

resource specialists.

Forest Management

Information about the hazards and limitations that

should be considered in areas used as forestland is

given in tables 11, 12, 13, and 14.

Features Affecting Use of Tree-Harvesting

Equipment

Table 11 provides information regarding the use of

tree-harvesting equipment. On most soils spring is the

most limiting season because of alternate thawing and

freezing during periods of snowmelt. The freezing and

thawing result in saturation and low strength in the

surface soil layers. When thawing is complete,

saturation continues for short periods in well drained

soils to nearly all year in very poorly drained

depressional soils. The degree of wetness generally is

determined by depth to the water table and the length

of the period when the water table is high. The water

table generally is lower in summer, when soil moisture

is heavily used by vegetation, and is closer to the

surface during periods when absorbed precipitation is

greater than the vegetative requirements. Harvesting
190 Soil Survey of

during periods of saturation usually results in severe

soil damage, except when the soil is frozen. The

preferred season for timber harvesting on many soils

is winter, when wetness and low soil strength can be

overcome by freezing.

The features shown in table 11 are as follows:

Slope.—The upper slope limit is more than 15

percent.

Flooding.—The soil is frequently flooded.

Wetness.—The soil is somewhat poorly drained,

poorly drained, or very poorly drained or has a

perched seasonal high water table (any drainage class).

Depth to hard bedrock.—The depth to hard bedrock

is less than 10 inches.

Susceptibility to rutting and wheel slippage (low

strength).—The AASHTO classification is A-6, A-7, or

A-8 in any layer at a depth of 20 inches or less.

Poor traction (loose sandy material).—The USDA

texture includes sands or loamy sands in any layer at

a depth of 10 inches or less.

Features Affecting Forest Haul Roads

Table 12 provides information regarding the use of

the soils as haul roads. Haul roads serve as

transportation routes from log landings to primary

roads. Generally, the haul roads are unpaved, but

some are graveled.

The features shown in table 12 are as follows:

Slope.—The slope is 8 percent or more.

Flooding.—The soil is frequently flooded.

Wetness.—The soil is somewhat poorly drained,

poorly drained, or very poorly drained or has a

perched seasonal high water table (any drainage

class).

Depth to hard bedrock.—The depth to hard bedrock

is less than 20 inches.

Low bearing strength.—The AASHTO classification

is A-6, A-7, or A-8 in any layer at a depth of 20 inches

or less.

Features Affecting Log Landings

Table 13 provides information regarding the use of

the soils as log landings. Log landings are areas

where logs are assembled for transportation. Areas

that require little or no cutting, filling, or surface

preparation are desired.

The features shown in table 13 are as follows:

Slope.—The slope is more than 6 percent.

Flooding.—The soil is occasionally flooded or

frequently flooded.

Wetness.—The soil is somewhat poorly drained,

poorly drained, or very poorly drained or has a

perched seasonal high water table (any drainage

class).

Susceptibility to rutting and wheel slippage (low

strength).—The AASHTO classification is A-6, A-7, or

A-8 in any layer at a depth of 20 inches or less.

Features Affecting Site Preparation and Planting

Table 14 shows the hazards and limitations

affecting site preparation and tree planting.

The features shown table 14 are as follows:

Slope.—The upper slope limit is more than 15

percent.

Flooding.—The soil is frequently flooded.

Wetness.—The soil is somewhat poorly drained,

poorly drained, or very poorly drained or has a

perched seasonal high water table (any drainage

class).

Depth to hard bedrock.—The depth to hard bedrock

is less than 20 inches.

Water erosion.—The slope is 8 percent or more.

Potential poor tilth and compaction.—The AASHTO

classification is A-6 or A-7 in the upper 10 inches.

Forest Productivity

In table 15, the potential productivity of

merchantable or common trees on a soil is expressed

as a site index and as a volume number. The site

index is the average height, in feet, that dominant and

codominant trees of a given species attain in a

specified number of years. The site index applies to

fully stocked, even-aged, unmanaged stands.

Commonly grown trees are those that forest managers

generally favor in intermediate or improvement

cuttings. They are selected on the basis of growth rate,

quality, value, and marketability. More detailed

information regarding site index is available in the

“National Forestry Manual,” which is available in local

offices of the Natural Resources Conservation Service

or on the Internet.

The volume of wood fiber, a number, is the yield

likely to be produced by the most important tree

species. This number, expressed as cubic feet per

acre per year and calculated at the age of culmination

of the mean annual increment (CMAI), indicates the

amount of fiber produced in a fully stocked, evenaged, unmanaged stand.

Trees to manage are those that are suitable for

commercial wood production.

Recreation

Will County has a wide variety of recreational areas,

including the Midewin National Tall Grass Prairie, the

Des Plaines Conservation Area, Kankakee River State

Park, the Illinois and Michigan Canal Corridor (fig. 7),
Will County, Illinois 191

and several county-owned forest preserves. An

assortment of outdoor activities is available to the

public, including boating, fishing, hiking, biking,

horseback riding, camping, and picnicking. Also, most

municipalities offer a variety of recreational facilities,

such as playgrounds, swimming pools, and golf

courses. Several private recreational facilities and

sportsmen’s clubs are in areas of mine spoil, where

numerous lakes have been created.

The soils of the survey area are rated in tables 16a

and 16b according to limitations that affect their

suitability for recreation. The ratings 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 the recreational uses. 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 tables 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).

The ratings in the tables are based on restrictive

soil features, such as wetness, slope, and texture of

the surface layer. Susceptibility to flooding is

considered. Not considered in the ratings, but

important in evaluating a site, are the location and

accessibility of the area, the size and shape of the

area and its scenic quality, vegetation, access to

water, potential water impoundment sites, and access

to public sewer lines. The capacity of the soil to absorb

septic tank effluent and the ability of the soil to support

vegetation also are important. Soils that are subject to

flooding are limited for recreational uses by the

duration and intensity of flooding and the season when

flooding occurs. In planning recreational facilities,

onsite assessment of the height, duration, intensity,

and frequency of flooding is essential.

The information in tables 16a and 16b can be

supplemented by other information in this survey, for

example, interpretations for building site development,

construction materials, sanitary facilities, and water

management.

Camp areas require site preparation, such as

shaping and leveling the tent and parking areas,

stabilizing roads and intensively used areas, and

installing sanitary facilities and utility lines. Camp

areas are subject to heavy foot traffic and some

vehicular traffic. The ratings are based on the soil

properties that affect the ease of developing camp

areas and the performance of the areas after

development. Slope, stoniness, and depth to bedrock

or a cemented pan are the main concerns affecting

the development of camp areas. The soil properties

that affect the performance of the areas after

development are those that influence trafficability and

promote the growth of vegetation, especially in heavily

used areas. For good trafficability, the surface of camp

areas should absorb rainfall readily, remain firm under

Figure 7.—The Channahon lock house on the historic Illinois

and Michigan Canal. The Illinois and Michigan Canal

Corridor is now used for recreational purposes, such as

hiking, biking, and boating.
192 Soil Survey of

heavy foot traffic, and not be dusty when dry. The soil

properties that influence trafficability are texture of the

surface layer, depth to a water table, ponding, flooding,

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Picnic areas are subject to heavy foot traffic. Most

vehicular traffic is confined to access roads and

parking areas. The ratings are based on the soil

properties that affect the ease of developing picnic

areas and that influence trafficability and the growth of

vegetation after development. Slope and stoniness are

the main concerns affecting the development of picnic

areas. For good trafficability, the surface of picnic

areas should absorb rainfall readily, remain firm under

heavy foot traffic, and not be dusty when dry. The soil

properties that influence trafficability are texture of the

surface layer, depth to a water table, ponding, flooding,

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Playgrounds require soils that are nearly level, are

free of stones, and can withstand intensive foot traffic.

The ratings are based on the soil properties that affect

the ease of developing playgrounds and that influence

trafficability and the growth of vegetation after

development. Slope and stoniness are the main

concerns affecting the development of playgrounds.

For good trafficability, the surface of the playgrounds

should absorb rainfall readily, remain firm under heavy

foot traffic, and not be dusty when dry. The soil

properties that influence trafficability are texture of the

surface layer, depth to a water table, ponding, flooding,

permeability, and large stones. The soil properties that

affect the growth of plants are depth to bedrock or a

cemented pan, permeability, and toxic substances in

the soil.

Paths and trails for hiking and horseback riding

should require little or no slope modification through

cutting and filling. The ratings are based on the soil

properties that affect trafficability and erodibility. These

properties are stoniness, depth to a water table,

ponding, flooding, slope, and texture of the surface

layer.

Off-road motorcycle trails require little or no site

preparation. They are not covered with surfacing

material or vegetation. Considerable compaction of the

soil material is likely. The ratings are based on the soil

properties that influence erodibility, trafficability,

dustiness, and the ease of revegetation. These

properties are stoniness, slope, depth to a water table,

ponding, flooding, and texture of the surface layer.

Golf fairways are subject to heavy foot traffic and

some light vehicular traffic. Cutting or filling may be

required. Irrigation is not considered in the ratings. The

ratings are based on the soil properties that affect

plant growth and trafficability after vegetation is

established. The properties that affect plant growth are

reaction; depth to a water table; ponding; depth to

bedrock or a cemented pan; the available water

capacity in the upper 40 inches; the content of salts,

sodium, or calcium carbonate; and sulfidic materials.

The properties that affect trafficability are flooding,

depth to a water table, ponding, slope, stoniness, and

the amount of sand, clay, or organic matter in the

surface layer. The suitability of the soil for traps, tees,

roughs, and greens is not considered in the ratings.

Wildlife Habitat

Because of diverse topography resulting primarily

from glacial action, Will County provides a variety of

aquatic and upland habitats that support an

abundance of wildlife species. The characteristic

aquatic habitats include several rivers, numerous

streams, and wetlands. The wetland types include

marshes, glacial potholes, hillside seeps, and floodplain wetlands along streams and rivers. These areas

of wetland provide important storm-water storage and

water quality benefits to the county as well as habitat

for such species as ducks, geese, great blue herons,

muskrat, mink, beaver, and numerous frogs, toads,

and turtles.

The upland areas, which range from steep to gently

sloping hillsides and ridges to nearly level terraces and

outwash plains, were once covered by a sea of native

prairie grasses and small open oak woodlands known

as savannas. These natural communities were once

home to such species as buffalo, prairie chickens, and

wolves. As the county was settled, conversion of land

for agriculture and urbanization altered these natural

communities and the wildlife populations associated

with them. The landscape in Will County is now a

mosaic of urban development, cropland, pasture,

small woodlots, and wetlands and other waterways

supporting wildlife species that have adapted to the

human-altered landscape. These species include

white-tailed deer, mallards, pheasants, squirrels,

crows, cardinals, house sparrows, raccoons, foxes,

and coyotes.

In general, most of the land in the county is not

managed primarily for wildlife. Good land management

practices, however, commonly improve the habitat for

wildlife. For example, farm practices that leave crop

residue on the fields during the fall and winter months

not only help to control erosion but also provide winter
Will County, Illinois 193

cover and food for some wildlife species. Allowing

grassed waterways, road ditches, fence lines, setaside fields, and vacant properties to remain

unmowed until early August provides much-needed

habitat for ground-nesting wildlife, such as rabbits,

pheasants, and many species of songbirds.

Many temporarily and seasonally flooded wetlands

have been impacted by land use practices.

Development and cultivation of these wetlands should

be avoided. Buffer strips surrounding wetland areas

provide food and nesting cover for many wildlife

species and keep these areas from filling in with

eroded sediment. Wetlands, streambanks, and

woodlots should be fenced so that livestock are

excluded. Fencing protects and maintains the native

plant communities that support wildlife species, helps

to control erosion, and improves water quality in

streams and rivers.

Soils affect the kind and amount of vegetation that

is available to wildlife as food and cover. They also

affect the construction of water impoundments. The

kind and abundance of wildlife depend largely on the

amount and distribution of food, cover, and water.

Wildlife habitat can be created or improved by planting

appropriate vegetation, by maintaining the existing

plant cover, or by promoting the natural establishment

of desirable plants.

In table 17, the soils in the survey area are rated

according to their potential for providing habitat for

various kinds of wildlife. This information can be used

in planning parks, wildlife refuges, nature study areas,

and other developments for wildlife; in selecting soils

that are suitable for establishing, improving, or

maintaining specific elements of wildlife habitat; and in

determining the intensity of management needed for

each element of the habitat.

The potential of the soil is rated good, fair, poor, or

very poor. A rating of good indicates that the element

or kind of habitat is easily established, improved, or

maintained. Few or no limitations affect management,

and satisfactory results can be expected. A rating of

fair indicates that the element or kind of habitat can be

established, improved, or maintained in most places.

Moderately intensive management is required for

satisfactory results. A rating of poor indicates that

limitations are severe for the designated element or

kind of habitat. Habitat can be created, improved, or

maintained in most places, but management is difficult

and must be intensive. A rating of very poor indicates

that restrictions for the element or kind of habitat are

very severe and that unsatisfactory results can be

expected. Creating, improving, or maintaining habitat

is impractical or impossible.

The elements of wildlife habitat are described in the

following paragraphs.

Grain and seed crops are domestic grains and

seed-producing herbaceous plants. Soil properties

and features that affect the growth of grain and seed

crops are depth of the root zone, texture of the surface

layer, available water capacity, wetness, slope, surface

stoniness, and flooding. Soil temperature and soil

moisture also are considerations. Examples of grain

and seed crops are corn, soybeans, wheat, oats, and

barley.

Grasses and legumes are domestic perennial

grasses and herbaceous legumes. Soil properties and

features that affect the growth of grasses and legumes

are depth of the root zone, texture of the surface layer,

available water capacity, wetness, surface stoniness,

flooding, and slope. Soil temperature and soil moisture

also are considerations. Examples of grasses and

legumes are bromegrass, timothy, orchardgrass,

clover, alfalfa, and birdsfoot trefoil.

Wild herbaceous plants are native or naturally

established grasses and forbs, including weeds. Soil

properties and features that affect the growth of these

plants are depth of the root zone, texture of the

surface layer, available water capacity, wetness,

surface stoniness, and flooding. Soil temperature and

soil moisture also are considerations. Examples of wild

herbaceous plants are bluestem, indiangrass,

blueberry, goldenrod, lambsquarters, dandelions,

blackberry, ragweed, wheatgrass, and nightshade.

Hardwood trees and woody understory produce

nuts or other fruit, buds, catkins, twigs, bark, and

foliage. Soil properties and features that affect the

growth of hardwood trees and shrubs are depth of the

root zone, available water capacity, and wetness.

Examples of these plants are oak, poplar, boxelder,

birch, maple, green ash, willow, and American elm.

Examples of fruit-producing shrubs that are suitable

for planting on soils rated good are American plum,

hazelnut, dogwood, and arrowwood.

Coniferous plants furnish browse and seeds. Soil

properties and features that affect the growth of

coniferous trees, shrubs, and ground cover are depth

of the root zone, available water capacity, and

wetness. Examples of coniferous plants are pine,

spruce, cedar, and tamarack.

Wetland plants are annual and perennial wild

herbaceous plants that grow on moist or wet sites.

Submerged or floating aquatic plants are excluded.

Soil properties and features affecting wetland plants

are texture of the surface layer, wetness, reaction,

salinity, slope, and surface stoniness. Examples of

wetland plants are smartweed, wild millet, cordgrass,
194 Soil Survey of

rushes, sedges, wild rice, arrowhead, waterplantain,

cattail, and prairie cordgrass.

Shallow water areas have an average depth of less

than 5 feet. Some are naturally wet areas. Others are

created by dams, levees, or other water-control

structures. Soil properties and features affecting

shallow water areas are depth to bedrock, wetness,

surface stoniness, slope, and permeability. Examples

of shallow water areas are waterfowl feeding areas,

wildlife watering developments, marshes, and beaver

ponds and other wildlife ponds.

The habitat for various kinds of wildlife is described

in the following paragraphs.

Habitat for openland wildlife consists of cropland,

pasture, meadows, and areas that are overgrown with

grasses, herbs, shrubs, and vines. These areas

produce grain and seed crops, grasses and legumes,

and wild herbaceous plants. Wildlife attracted to these

areas include Hungarian partridge, ring-necked

pheasant, bobwhite quail, sharp-tailed grouse,

meadowlark, field sparrow, killdeer, cottontail rabbit,

and red fox.

Habitat for woodland wildlife consists of areas of

deciduous and/or coniferous plants and associated

grasses, legumes, and wild herbaceous plants. Wildlife

attracted to these areas include wild turkey, ruffed

grouse, thrushes, woodpeckers, owls, tree squirrels,

raccoon, and white-tailed deer.

Habitat for wetland wildlife consists of open, marshy

or swampy shallow water areas (fig. 8). Some of the

wildlife attracted to such areas are ducks, geese,

herons, bitterns, rails, kingfishers, muskrat, otter, mink,

beaver, and turtles.

Engineering

This section provides information for planning land

uses related to urban development and to water

management. Soils are rated for various uses, and the

most limiting features are identified. Ratings are given

for building site development, sanitary facilities,

construction materials, and water management. The

ratings are based on observed performance of the

soils and on the data in the tables described under the

heading “Soil Properties.”

Information in this section 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 section. Local ordinances and

regulations should be considered in planning, in site

selection, and in design.

Soil properties, site features, and observed

performance were considered in determining the

ratings in this section. During the fieldwork for this soil

survey, determinations were made about particle-size

distribution, liquid limit, plasticity index, soil reaction,

depth to bedrock, hardness of bedrock within 5 to 7

feet of the surface, soil wetness, depth to a water

table, ponding, slope, likelihood of flooding, natural soil

structure aggregation, and soil density. Data were

collected about kinds of clay minerals, mineralogy of

the sand and silt fractions, and the kinds of adsorbed

cations. Estimates were made for erodibility,

permeability, corrosivity, shrink-swell potential,

available water capacity, and other behavioral

characteristics affecting engineering uses.

This information can be used to evaluate the

potential of areas for residential, commercial,

industrial, and recreational uses; make preliminary

estimates of construction conditions; evaluate

alternative routes for roads, streets, highways,

pipelines, and underground cables; evaluate

alternative sites for sanitary landfills, septic tank

absorption fields, and sewage lagoons; plan detailed

onsite investigations of soils and geology; locate

potential sources of gravel, sand, earthfill, and topsoil;

plan drainage systems, irrigation systems, ponds,

terraces, and other structures for soil and water

conservation; and predict performance of proposed

small structures and pavements by comparing the

performance of existing similar structures on the same

or similar soils.

The information in the tables, along with the soil

maps, the soil descriptions, and other data provided in

this survey, can be used to make additional

interpretations.

Some of the terms used in this soil survey have a

special meaning in soil science and are defined in the

Glossary.
Will County, Illinois 195

Building Site Development

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. Tables 18a and

18b show the degree and kind of soil limitations that

affect dwellings with and without basements, small

commercial buildings, local roads and streets, shallow

excavations, and lawns and landscaping.

The ratings in the tables 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 tables 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,

Figure 8.—A pothole of Houghton muck, undrained, 0 to 2 percent slopes. This soil provides good habitat for a wide a variety of

wetland wildlife species.
196 Soil Survey of

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.

Local roads and streets have an all-weather surface

and carry automobile and light truck traffic all year.

They have a subgrade of cut or fill soil material; a base

of gravel, crushed rock, or soil material stabilized by

lime or cement; and a surface of flexible material

(asphalt), rigid material (concrete), or gravel with a

binder. The ratings are based on the soil properties

that affect the ease of excavation and grading and the

traffic-supporting capacity. The properties that affect

the ease of excavation and grading are depth to

bedrock or a cemented pan, hardness of bedrock or a

cemented pan, depth to a water table, ponding,

flooding, the amount of large stones, and slope. The

properties that affect the traffic-supporting capacity

are soil strength (as inferred from the AASHTO group

index number), subsidence, linear extensibility (shrinkswell potential), the potential for frost action, depth to a

water table, and ponding.

Shallow excavations are trenches or holes dug to a

maximum depth of 5 or 6 feet for graves, utility lines,

open ditches, or other purposes. The ratings are

based on the soil properties that influence the ease of

digging and the resistance to sloughing. Depth to

bedrock or a cemented pan, hardness of bedrock or a

cemented pan, the amount of large stones, and dense

layers influence the ease of digging, filling, and

compacting. Depth to the seasonal high water table,

flooding, and ponding may restrict the period when

excavations can be made. Slope influences the ease

of using machinery. Soil texture, depth to the water

table, and linear extensibility (shrink-swell potential)

influence the resistance to sloughing.

Lawns and landscaping require soils on which turf

and ornamental trees and shrubs can be established

and maintained. Irrigation is not considered in the

ratings. The ratings are based on the soil properties

that affect plant growth and trafficability after

vegetation is established. The properties that affect

plant growth are reaction; depth to a water table;

ponding; depth to bedrock or a cemented pan; the

available water capacity in the upper 40 inches; the

content of salts, sodium, or calcium carbonate; and

sulfidic materials. The properties that affect

trafficability are flooding, depth to a water table,

ponding, slope, stoniness, and the amount of sand,

clay, or organic matter in the surface layer.

Sanitary Facilities

Tables 19a and 19b show the degree and kind of

soil limitations that affect septic tank absorption fields,

sewage lagoons, sanitary landfills, and daily cover for

landfill. The ratings 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

these uses. 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 tables indicate the severity

of individual limitations. The ratings are shown as

decimal fractions ranging from 0.01 to 1.00. They
Will County, Illinois 197

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).

Septic tank absorption fields are areas in which

effluent from a septic tank is distributed into the soil

through subsurface tiles or perforated pipe. Only that

part of the soil between depths of 24 and 60 inches is

evaluated. The ratings are based on the soil properties

that affect absorption of the effluent, construction and

maintenance of the system, and public health.

Permeability, depth to a water table, ponding, depth to

bedrock or a cemented pan, and flooding affect

absorption of the effluent. Stones and boulders, ice,

and bedrock or a cemented pan interfere with

installation. Subsidence interferes with installation and

maintenance. Excessive slope may cause lateral

seepage and surfacing of the effluent in downslope

areas.

Some soils are underlain by loose sand and gravel

or fractured bedrock at a depth of less than 4 feet

below the distribution lines. In these soils the

absorption field may not adequately filter the effluent,

particularly when the system is new. As a result, the

ground water may become contaminated.

Sewage lagoons are shallow ponds constructed to

hold sewage while aerobic bacteria decompose the

solid and liquid wastes. Lagoons should have a nearly

level floor surrounded by cut slopes or embankments

of compacted soil. Nearly impervious soil material for

the lagoon floor and sides is required to minimize

seepage and contamination of ground water.

Considered in the ratings are slope, permeability,

depth to a water table, ponding, depth to bedrock or a

cemented pan, flooding, large stones, and content of

organic matter.

Soil permeability is a critical property affecting the

suitability for sewage lagoons. Most porous soils

eventually become sealed when they are used as sites

for sewage lagoons. Until sealing occurs, however, the

hazard of pollution is severe. Soils that have a

permeability rate of more than 2 inches per hour are

too porous for the proper functioning of sewage

lagoons. In these soils, seepage of the effluent can

result in contamination of the ground water. Groundwater contamination is also a hazard if fractured

bedrock is within a depth of 40 inches, if the water

table is high enough to raise the level of sewage in the

lagoon, or if floodwater overtops the lagoon.

A high content of organic matter is detrimental to

proper functioning of the lagoon because it inhibits

aerobic activity. Slope, bedrock, and cemented pans

can cause construction problems, and large stones

can hinder compaction of the lagoon floor. If the

lagoon is to be uniformly deep throughout, the slope

must be gentle enough and the soil material must be

thick enough over bedrock or a cemented pan to make

land smoothing practical.

A trench sanitary landfill is an area where solid

waste is placed in successive layers in an excavated

trench. The waste is spread, compacted, and covered

daily with a thin layer of soil excavated at the site.

When the trench is full, a final cover of soil material at

least 2 feet thick is placed over the landfill. The ratings

in the table are based on the soil properties that affect

the risk of pollution, the ease of excavation,

trafficability, and revegetation. These properties

include permeability, depth to bedrock or a cemented

pan, depth to a water table, ponding, slope, flooding,

texture, stones and boulders, highly organic layers,

soil reaction, and content of salts and sodium. Unless

otherwise stated, the ratings apply only to that part of

the soil within a depth of about 6 feet. For deeper

trenches, onsite investigation may be needed.

Hard, nonrippable bedrock, creviced bedrock, or

highly permeable strata in or directly below the

proposed trench bottom can affect the ease of

excavation and the hazard of ground-water pollution.

Slope affects construction of the trenches and the

movement of surface water around the landfill. It also

affects the construction and performance of roads in

areas of the landfill.

Soil texture and consistence affect the ease with

which the trench is dug and the ease with which the

soil can be used as daily or final cover. They

determine the workability of the soil when dry and

when wet. Soils that are plastic and sticky when wet

are difficult to excavate, grade, or compact and are

difficult to place as a uniformly thick cover over a layer

of refuse.

The soil material used as the final cover for a trench

landfill should be suitable for plants. It should not have

excess sodium or salts and should not be too acid.

The surface layer generally has the best workability,

the highest content of organic matter, and the best

potential for plants. Material from the surface layer

should be stockpiled for use as the final cover.

In an area sanitary landfill, solid waste is placed in

successive layers on the surface of the soil. The waste

is spread, compacted, and covered daily with a thin

layer of soil from a source away from the site. A final

cover of soil material at least 2 feet thick is placed over

the completed landfill. The ratings in the table are

based on the soil properties that affect trafficability and
198 Soil Survey of

the risk of pollution. These properties include flooding,

permeability, depth to a water table, ponding, slope,

and depth to bedrock or a cemented pan.

Flooding is a serious problem because it can result

in pollution in areas downstream from the landfill. If

permeability is too rapid or if fractured bedrock, a

fractured cemented pan, or the water table is close to

the surface, the leachate can contaminate the water

supply. Slope is a consideration because of the extra

grading required to maintain roads in the steeper

areas of the landfill. Also, leachate may flow along the

surface of the soils in the steeper areas and cause

difficult seepage problems.

Daily cover for landfill is the soil material that is

used to cover compacted solid waste in an area

sanitary landfill. The soil material is obtained offsite,

transported to the landfill, and spread over the waste.

The ratings in the table also apply to the final cover for

a landfill. They are based on the soil properties that

affect workability, the ease of digging, and the ease

of moving and spreading the material over the refuse

daily during wet and dry periods. These properties

include soil texture, depth to a water table, ponding,

rock fragments, slope, depth to bedrock or a

cemented pan, reaction, and content of salts, sodium,

or lime.

Loamy or silty soils that are free of large stones and

excess gravel are the best cover for a landfill. Clayey

soils may be sticky and difficult to spread; sandy soils

are subject to wind erosion.

Slope affects the ease of excavation and of moving

the cover material. Also, it can influence runoff,

erosion, and reclamation of the borrow area.

After soil material has been removed, the soil

material remaining in the borrow area must be thick

enough over bedrock, a cemented pan, or the water

table to permit revegetation. The soil material used as

the final cover for a landfill should be suitable for

plants. It should not have excess sodium, salts, or lime

and should not be too acid.

Construction Materials

Tables 20a and 20b give information about the soils

as potential sources of gravel, sand, reclamation

material, roadfill, and topsoil. Normal compaction,

minor processing, and other standard construction

practices are assumed.

Sand and gravel are natural aggregates suitable for

commercial use with a minimum of processing. They

are used in many kinds of construction. Specifications

for each use vary widely. In table 20a, only the

likelihood of finding material in suitable quantity is

evaluated. The suitability of the material for specific

purposes is not evaluated, nor are factors that affect

excavation of the material. The properties used to

evaluate the soil as a source of sand or gravel are

gradation of grain sizes (as indicated by the Unified

classification of the soil), the thickness of suitable

material, and the content of rock fragments. If the

bottom layer of the soil contains sand or gravel, the

soil is considered a likely source regardless of

thickness. The assumption is that the sand or gravel

layer below the depth of observation exceeds the

minimum thickness.

The soils are rated good, fair, or poor as potential

sources of sand and gravel. A rating of good or fair

means that the source material is likely to be in or

below the soil. The bottom layer and the thickest layer

of the soils are assigned numerical ratings. These

ratings indicate the likelihood that the layer is a source

of sand or gravel. The number 0.00 indicates that the

layer is a poor source. The number 1.00 indicates that

the layer is a good source. A number between 0.00

and 1.00 indicates the degree to which the layer is a

likely source.

The soils are rated good, fair, or poor as potential

sources of reclamation material, roadfill, and topsoil.

The features that limit the soils as sources of these

materials are specified in the tables. The numerical

ratings given after the specified features indicate the

degree to which the features limit the soils as sources

of reclamation material, roadfill, or topsoil. The lower

the number, the greater the limitation.

Reclamation material is used in areas that have

been drastically disturbed by surface mining or similar

activities. When these areas are reclaimed, layers of

soil material or unconsolidated geological material, or

both, are replaced in a vertical sequence. The

reconstructed soil favors plant growth. The ratings in

the table do not apply to quarries and other mined

areas that require an offsite source of reconstruction

material. The ratings are based on the soil properties

that affect erosion and stability of the surface and the

productive potential of the reconstructed soil. These

properties include the content of sodium, salts, and

calcium carbonate; reaction; available water capacity;

erodibility; texture; content of rock fragments; and

content of organic matter and other features that affect

fertility.

Roadfill is soil material that is excavated in one

place and used in road embankments in another

place. In this table, the soils are rated as a source of

roadfill for low embankments, generally less than 6

feet high and less exacting in design than higher

embankments.

The ratings are for the whole soil, from the surface

to a depth of about 5 feet. It is assumed that soil layers
Will County, Illinois 199

will be mixed when the soil material is excavated and

spread.

The ratings are based on the amount of suitable

material and on soil properties that affect the ease of

excavation and the performance of the material after it

is in place. The thickness of the suitable material is a

major consideration. The ease of excavation is

affected by large stones, depth to a water table, and

slope. How well the soil performs in place after it has

been compacted and drained is determined by its

strength (as inferred from the AASHTO classification

of the soil) and linear extensibility (shrink-swell

potential).

Topsoil is used to cover an area so that vegetation

can be established and maintained. The upper 40

inches of a soil is evaluated for use as topsoil. Also

evaluated is the reclamation potential of the borrow

area. The ratings are based on the soil properties that

affect plant growth; the ease of excavating, loading,

and spreading the material; and reclamation of the

borrow area. Toxic substances, soil reaction, and the

properties that are inferred from soil texture, such as

available water capacity and fertility, affect plant

growth. The ease of excavating, loading, and

spreading is affected by rock fragments, slope, depth

to a water table, soil texture, and thickness of suitable

material. Reclamation of the borrow area is affected by

slope, depth to a water table, rock fragments, depth to

bedrock or a cemented pan, and toxic material.

The surface layer of most soils is generally

preferred for topsoil because of its organic matter

content. Organic matter greatly increases the

absorption and retention of moisture and nutrients for

plant growth.

Water Management

Tables 21a and 21b give information on the soil

properties and site features that affect water

management. The degree and kind of soil limitations

are given for pond reservoir areas; embankments,

dikes, and levees; aquifer-fed excavated ponds;

grassed waterways and surface drains; terraces and

diversions; tile drains and underground outlets; and

sprinkler irrigation. The ratings 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 these uses. 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 tables 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).

Pond reservoir areas hold water behind a dam or

embankment. Soils best suited to this use have low

seepage potential in the upper 60 inches. The

seepage potential is determined by the permeability of

the soil and the depth to fractured bedrock or other

permeable material. Excessive slope can affect the

storage capacity of the reservoir area.

Embankments, dikes, and levees are raised

structures of soil material, generally less than 20 feet

high, constructed to impound water or to protect land

against overflow. Embankments that have zoned

construction (core and shell) are not considered. In

table 21a, the soils are rated as a source of material

for embankment fill. The ratings apply to the soil

material below the surface layer to a depth of about 5

feet. It is assumed that soil layers will be uniformly

mixed and compacted during construction.

The ratings do not indicate the ability of the natural

soil to support an embankment. Soil properties to a

depth even greater than the height of the embankment

can affect performance and safety of the embankment.

Generally, deeper onsite investigation is needed to

determine these properties.

Soil material in embankments must be resistant to

seepage, piping, and erosion and have favorable

compaction characteristics. Unfavorable features

include less than 5 feet of suitable material and a high

content of stones or boulders, organic matter, or salts

or sodium. A high water table affects the amount of

usable material. It also affects trafficability.

Aquifer-fed excavated ponds are pits or dugouts

that extend to a ground-water aquifer or to a depth

below a permanent water table. Excluded are ponds

that are fed only by surface runoff and embankment

ponds that impound water 3 feet or more above the

original surface. Excavated ponds are affected by

depth to a permanent water table, permeability of the
200

aquifer, and quality of the water as inferred from the

salinity of the soil. Depth to bedrock and the content of

large stones affect the ease of excavation.

Grassed waterways and surface drains are natural

or constructed channels, generally broad and shallow,

that conduct surface water to outlets at a nonerosive

velocity. Large stones, wetness, slope, and depth to

bedrock or a cemented pan affect the construction of

grassed waterways. A hazard of wind erosion, low

available water capacity, restricted rooting depth, toxic

substances such as salts and sodium, and restricted

permeability adversely affect the growth and

maintenance of the grass after construction.

Terraces and diversions are embankments or a

combination of channels and ridges constructed

across a slope to control erosion and conserve

moisture by intercepting runoff. Slope, wetness, large

stones, and depth to bedrock or a cemented pan affect

the construction of terraces and diversions. A

restricted rooting depth, a severe hazard of wind

erosion or water erosion, an excessively coarse

texture, and restricted permeability adversely affect

maintenance.

Tile drains and underground outlets remove excess

surface and subsurface water from the soil. How easily

and effectively the soil is drained depends on the

depth to bedrock or other layers that affect the rate of

water movement; permeability; depth to a high water

table or depth of standing water if the soil is subject to

ponding; slope; susceptibility to flooding; subsidence of

organic layers; and the potential for frost action.

Excavating and grading and the stability of ditchbanks

are affected by depth to bedrock, large stones, slope,

and the hazard of cutbanks caving. The productivity of

the soil after drainage is adversely affected by extreme

acidity or by toxic substances in the root zone, such as

salts, sodium, and sulfur.

Sprinkler irrigation is the controlled application of

water to supplement rainfall and support plant growth.

The design and management of an irrigation system

are affected by depth to the water table, the need for

drainage, flooding, available water capacity, intake

rate, permeability, erosion hazard, and slope. The

construction of a system is affected by large stones

and depth to bedrock or to a cemented pan. The

performance of a system is affected by the depth of

the root zone, the amount of salts or sodium, and soil

reaction.

Waste Management

Soil properties are important when organic waste is

applied as fertilizer and wastewater is applied in

irrigated areas. They also are important when the soil

is used as a medium for the treatment and disposal of

the organic waste and wastewater. Unfavorable soil

properties can result in environmental damage.

The use of organic waste and wastewater as

production resources results in energy and resource

conservation and minimizes the problems associated

with waste disposal. If disposal is the goal, applying a

maximum amount of the organic waste or the

wastewater to a minimal area holds costs to a

minimum and environmental damage is the main

hazard. If reuse is the goal, a minimum amount should

be applied to a maximum area and environmental

damage is unlikely.

Interpretations developed for waste management

may include ratings for manure, food-processing

waste, municipal sewage sludge, use of wastewater

for irrigation, and treatment of wastewater by slow

rate, overland flow, and rapid infiltration processes.

Specific information regarding waste management

is available at the local office of the Natural Resources

Conservation Service or the Cooperative Extension

Service.
201

Data relating to soil properties are collected during

the course of the soil survey.

Soil properties are ascertained by field examination

of the soils and by laboratory index testing of some

benchmark soils. Established standard procedures are

followed. During the survey, many shallow borings are

made and examined to identify and classify the soils

and to delineate them on the soil maps. Samples are

taken from some typical profiles and tested in the

laboratory to determine particle-size distribution,

plasticity, and compaction characteristics.

Estimates of soil properties are based on field

examinations, on laboratory tests of samples from the

survey area, and on laboratory tests of samples of

similar soils in nearby areas. Tests verify field

observations, verify properties that cannot be

estimated accurately by field observation, and help to

characterize key soils.

The estimates of soil properties are shown in

tables. They include engineering index properties,

physical and chemical properties, and pertinent soil

and water features.

Engineering Index Properties

Table 22 gives the engineering classifications and

the range of index properties for the layers of each soil

in the survey area.

Depth to the upper and lower boundaries of each

layer is indicated.

Texture is given in the standard terms used by the

U.S. Department of Agriculture. These terms are

defined according to percentages of sand, silt, and

clay in the fraction of the soil that is less than 2

millimeters in diameter (fig. 9). “Loam,” for example, is

soil that is 7 to 27 percent clay, 28 to 50 percent silt,

and less than 52 percent sand. If the content of

particles coarser than sand is 15 percent or more, an

appropriate modifier is added, for example, “gravelly.”

Textural terms are defined in the Glossary.

Classification of the soils is determined according to

the Unified soil classification system (ASTM, 2001)

and the system adopted by the American Association

of State Highway and Transportation Officials

(AASHTO, 2000).

The Unified system classifies soils according to

properties that affect their use as construction

material. Soils are classified according to particle-size

distribution of the fraction less than 3 inches in

diameter and according to plasticity index, liquid limit,

and organic matter content. Sandy and gravelly soils

are identified as GW, GP, GM, GC, SW, SP, SM, and

SC; silty and clayey soils as ML, CL, OL, MH, CH, and

OH; and highly organic soils as PT. Soils exhibiting

engineering properties of two groups can have a dual

classification, for example, CL-ML.

The AASHTO system classifies soils according to

those properties that affect roadway construction and

maintenance. In this system, the fraction of a mineral

soil that is less than 3 inches in diameter is classified

in one of seven groups from A-1 through A-7 on the

basis of particle-size distribution, liquid limit, and

plasticity index. Soils in group A-1 are coarse grained

and low in content of fines (silt and clay). At the other

extreme, soils in group A-7 are fine grained. Highly

organic soils are classified in group A-8 on the basis of

visual inspection.

Soil Properties

Figure 9.—Percentages of clay, silt, and sand in the basic

USDA soil texture classes.
202 Soil Survey of

If laboratory data are available, the A-1, A-2, and A7 groups are further classified as A-1-a, A-1-b, A-2-4,

A-2-5, A-2-6, A-2-7, A-7-5, or A-7-6. As an additional

refinement, the suitability of a soil as subgrade

material can be indicated by a group index number.

Group index numbers range from 0 for the best

subgrade material to 20 or higher for the poorest.

Rock fragments larger than 10 inches in diameter

and 3 to 10 inches in diameter are indicated as a

percentage of the total soil on a dry-weight basis. The

percentages are estimates determined mainly by

converting volume percentage in the field to weight

percentage.

Percentage (of soil particles) passing designated

sieves is the percentage of the soil fraction less than 3

inches in diameter based on an ovendry weight. The

sieves, numbers 4, 10, 40, and 200 (USA Standard

Series), have openings of 4.76, 2.00, 0.420, and 0.074

millimeters, respectively. Estimates are based on

laboratory tests of soils sampled in the survey area

and in nearby areas and on estimates made in the

field.

Liquid limit and plasticity index (Atterberg limits)

indicate the plasticity characteristics of a soil. The

estimates are based on test data from the survey area

or from nearby areas and on field examination.

The estimates of particle-size distribution, liquid

limit, and plasticity index are generally rounded to the

nearest 5 percent. Thus, if the ranges of gradation and

Atterberg limits extend a marginal amount (1 or 2

percentage points) across classification boundaries,

the classification in the marginal zone is generally

omitted in the table.

Physical Properties

Table 23 shows estimates of some physical

characteristics and features that affect soil behavior.

These estimates are given for the layers of each soil in

the survey area. The estimates are based on field

observations and on test data for these and similar soils.

Depth to the upper and lower boundaries of each

layer is indicated.

Clay as a soil separate consists of mineral soil

particles that are less than 0.002 millimeter in

diameter. In the table, the estimated clay content of

each major soil layer is given as a percentage, by

weight, of the soil material that is less than 2

millimeters in diameter.

The amount and kind of clay greatly affect the

fertility and physical condition of the soil. They

determine the ability of the soil to adsorb cations and

to retain moisture. They influence shrink-swell

potential, permeability, plasticity, the ease of soil

dispersion, and other soil properties. The amount and

kind of clay in a soil also affect tillage and earthmoving operations.

Moist bulk density is the weight of soil (ovendry) per

unit volume. Volume is measured when the soil is at

field moisture capacity, that is, the moisture content at

1

/3- or 1/10-bar (33kPa or 10kPa) moisture tension.

Weight is determined after the soil is dried at 105

degrees C. In table 23, the estimated moist bulk

density of each soil horizon is expressed in grams per

cubic centimeter of soil material that is less than 2

millimeters in diameter. Bulk density data are used to

compute shrink-swell potential, available water

capacity, total pore space, and other soil properties.

The moist bulk density of a soil indicates the pore

space available for water and roots. Depending on soil

texture, a bulk density of more than 1.4 can restrict

water storage and root penetration. Moist bulk density

is influenced by texture, kind of clay, content of organic

matter, and soil structure.

Permeability (Ksat ) refers to the ability of a soil to

transmit water or air. The term “permeability,” as used

in soil surveys, indicates saturated hydraulic

conductivity (Ksat ). The estimates in table 23 indicate

the rate of water movement, in inches per hour, when

the soil is saturated. They are based on soil

characteristics observed in the field, particularly

structure, porosity, and texture. Permeability is

considered in the design of soil drainage systems and

septic tank absorption fields.

Available water capacity refers to the quantity of

water that the soil is capable of storing for use by

plants. The capacity for water storage is given in

inches of water per inch of soil for each soil layer. The

capacity varies, depending on soil properties that

affect retention of water. The most important

properties are the content of organic matter, soil

texture, bulk density, and soil structure. Available water

capacity is an important factor in the choice of plants

or crops to be grown and in the design and

management of irrigation systems. Available water

capacity is not an estimate of the quantity of water

actually available to plants at any given time.

Linear extensibility refers to the change in length of

an unconfined clod as moisture content is decreased

from a moist to a dry state. It is an expression of the

volume change between the water content of the clod

at 1/3- or 1/10-bar tension (33kPa or 10kPa tension) and

oven dryness. The volume change is reported in table

23 as percent change for the whole soil. Volume

change is influenced by the amount and type of clay

minerals in the soil.

Linear extensibility is used to determine the shrinkswell potential of soils. The shrink-swell potential is low
Will County, Illinois 203

if the soil has a linear extensibility of less than 3

percent; moderate if 3 to 6 percent; high if 6 to 9

percent; and very high if more than 9 percent. If the

linear extensibility is more than 3, shrinking and

swelling can cause damage to buildings, roads, and

other structures and to plant roots. Special design

commonly is needed.

Organic matter is the plant and animal residue in

the soil at various stages of decomposition. In table

23, the estimated content of organic matter is

expressed as a percentage, by weight, of the soil

material that is less than 2 millimeters in diameter.

The content of organic matter in a soil can be

maintained by returning crop residue to the soil.

Organic matter has a positive effect on available water

capacity, water infiltration, soil organism activity, and

tilth. It is a source of nitrogen and other nutrients for

crops and soil organisms.

Erosion factors are shown in table 23 as the K

factor (Kw and Kf) and the T factor. Erosion factor K

indicates the susceptibility of a soil to sheet and rill

erosion by water. Factor K is one of several factors

used in the Universal Soil Loss Equation (USLE) and

the Revised Universal Soil Loss Equation (RUSLE) to

predict the average annual rate of soil loss by sheet

and rill erosion in tons per acre per year. The

estimates are based primarily on percentage of silt,

sand, and organic matter and on soil structure and

permeability. Values of K range from 0.02 to 0.69.

Other factors being equal, the higher the value, the

more susceptible the soil is to sheet and rill erosion by

water.

Erosion factor Kw indicates the erodibility of the

whole soil. The estimates are modified by the

presence of rock fragments.

Erosion factor Kf indicates the erodibility of the fineearth fraction, or the material less than 2 millimeters in

size.

Erosion factor T is an estimate of the maximum

average annual rate of soil erosion by wind or water

that can occur without affecting crop productivity over

a sustained period. The rate is in tons per acre per

year.

Wind erodibility groups are made up of soils that

have similar properties affecting their susceptibility to

wind erosion in cultivated areas. The soils assigned to

group 1 are the most susceptible to wind erosion, and

those assigned to group 8 are the least susceptible.

The groups are described in the “National Soil Survey

Handbook” (USDA, NRCS).

Wind erodibility index is a numerical value indicating

the susceptibility of soil to wind erosion, or the tons

per acre per year that can be expected to be lost to

wind erosion. There is a close correlation between

wind erosion and the texture of the surface layer, the

size and durability of surface clods, rock fragments,

organic matter, and a calcareous reaction. Soil

moisture and frozen soil layers also influence wind

erosion.

Chemical Properties

Table 24 shows estimates of some chemical

characteristics and features that affect soil behavior.

These estimates are given for the layers of each soil in

the survey area. The estimates are based on field

observations and on test data for these and similar

soils.

Depth to the upper and lower boundaries of each

layer is indicated.

Soil reaction is a measure of acidity or alkalinity.

The pH of each soil horizon is based on many field

tests. For many soils, values have been verified by

laboratory analyses. Soil reaction is important in

selecting crops and other plants, in evaluating soil

amendments for fertility and stabilization, and in

determining the risk of corrosion.

Cation-exchange capacity is the total amount of

extractable bases that can be held by the soil,

expressed in terms of milliequivalents per 100 grams

of soil at neutrality (pH 7.0) or at some other stated pH

value. Soils having a low cation-exchange capacity

hold fewer cations and may require more frequent

applications of fertilizer than soils having a high cationexchange capacity. The ability to retain cations

reduces the hazard of ground-water pollution.

Calcium carbonate equivalent is the percent of

carbonates, by weight, in the fraction of the soil less

than 2 millimeters in size. The availability of plant

nutrients is influenced by the amount of carbonates in

the soil. Incorporating nitrogen fertilizer into calcareous

soils helps to prevent nitrite accumulation and

ammonium-N volatilization.

Water Features

Table 25 gives estimates of various water features.

The estimates are used in land use planning that

involves engineering considerations.

Hydrologic soil groups are based on estimates of

runoff potential. Soils are assigned to one of four

groups according to the rate of water infiltration when

the soils are not protected by vegetation, are

thoroughly wet, and receive precipitation from longduration storms.

The four hydrologic soil groups are:

Group A. Soils having a high infiltration rate (low

runoff potential) when thoroughly wet. These consist
204 Soil Survey of

mainly of deep, well drained to excessively drained

sands or gravelly sands. These soils have a high rate

of water transmission.

Group B. Soils having a moderate infiltration rate

when thoroughly wet. These consist chiefly of

moderately deep or deep, moderately well drained or

well drained soils that have moderately fine texture to

moderately coarse texture. These soils have a

moderate rate of water transmission.

Group C. Soils having a slow infiltration rate when

thoroughly wet. These consist chiefly of soils having a

layer that impedes the downward movement of water

or soils of moderately fine texture or fine texture.

These soils have a slow rate of water transmission.

Group D. Soils having a very slow infiltration rate

(high runoff potential) when thoroughly wet. These

consist chiefly of clays that have a high shrink-swell

potential, soils that have a high water table, soils that

have a claypan or clay layer at or near the surface,

and soils that are shallow over nearly impervious

material. These soils have a very slow rate of water

transmission.

The months in table 25 indicate the portion of the

year in which the feature is most likely to be a

concern.

Water table refers to a saturated zone in the soil.

Table 25 indicates, by month, depth to the top (upper

limit) and base (lower limit) of the saturated zone in

most years. Estimates of the upper and lower limits

are based mainly on observations of the water table at

selected sites and on evidence of a saturated zone,

namely grayish colors or mottles (redoximorphic

features) in the soil. A saturated zone that lasts for

less than a month is not considered a water table.

Ponding is standing water in a closed depression.

Unless a drainage system is installed, the water is

removed only by percolation, transpiration, or

evaporation. Table 25 indicates surface water depth

and the duration and frequency of ponding. Duration is

expressed as very brief if less than 2 days, brief if 2 to

7 days, long if 7 to 30 days, and very long if more than

30 days. Frequency is expressed as none, rare,

occasional, and frequent. None means that ponding is

not probable; rare that it is unlikely but possible under

unusual weather conditions (the chance of ponding is

nearly 0 percent to 5 percent in any year); occasional

that it occurs, on the average, once or less in 2 years

(the chance of ponding is 5 to 50 percent in any year);

and frequent that it occurs, on the average, more than

once in 2 years (the chance of ponding is more than

50 percent in any year).

Flooding is the temporary inundation of an area

caused by overflowing streams, by runoff from

adjacent slopes, or by tides. Water standing for short

periods after rainfall or snowmelt is not considered

flooding, and water standing in swamps and marshes

is considered ponding rather than flooding.

Duration and frequency are estimated. Duration is

expressed as extremely brief if 0.1 hour to 4 hours,

very brief if 4 hours to 2 days, brief if 2 to 7 days, long

if 7 to 30 days, and very long if more than 30 days.

Frequency is expressed as none, very rare, rare,

occasional, frequent, and very frequent. None means

that flooding is not probable; very rare that it is very

unlikely but possible under extremely unusual weather

conditions (the chance of flooding is less than 1

percent in any year); rare that it is unlikely but possible

under unusual weather conditions (the chance of

flooding is 1 to 5 percent in any year); occasional that

it occurs infrequently under normal weather conditions

(the chance of flooding is 5 to 50 percent in any year);

frequent that it is likely to occur often under normal

weather conditions (the chance of flooding is more

than 50 percent in any year but is less than 50 percent

in all months in any year); and very frequent that it is

likely to occur very often under normal weather

conditions (the chance of flooding is more than 50

percent in all months of any year).

The information is based on evidence in the soil

profile, namely thin strata of gravel, sand, silt, or clay

deposited by floodwater; irregular decrease in organic

matter content with increasing depth; and little or no

horizon development.

Also considered are local information about the

extent and levels of flooding and the relation of each

soil on the landscape to historic floods. Information on

the extent of flooding based on soil data is less

specific than that provided by detailed engineering

surveys that delineate flood-prone areas at specific

flood frequency levels.

Soil Features

Table 26 gives estimates of soil features. The

estimates are used in land use planning that involves

engineering considerations.

A restrictive layer is a nearly continuous layer that

has one or more physical, chemical, or thermal

properties that significantly impede the movement of

water and air through the soil or that restrict roots or

otherwise provide an unfavorable root environment.

Examples are bedrock, cemented layers, dense

layers, and frozen layers. The table indicates the

hardness and thickness of the restrictive layer, both of

which significantly affect the ease of excavation. Depth

to top is the vertical distance from the soil surface to

the upper boundary of the restrictive layer.

Subsidence is the settlement of organic soils or of
Will County, Illinois 205

saturated mineral soils of very low density. Subsidence

generally results from either desiccation and

shrinkage or oxidation of organic material, or both,

following drainage. Subsidence takes place gradually,

usually over a period of several years. The table shows

the expected initial subsidence, which usually is a

result of drainage, and total subsidence, which results

from a combination of factors.

Potential for frost action is the likelihood of upward

or lateral expansion of the soil caused by the formation

of segregated ice lenses (frost heave) and the

subsequent collapse of the soil and loss of strength on

thawing. Frost action occurs when moisture moves

into the freezing zone of the soil. Temperature, texture,

density, permeability, content of organic matter, and

depth to the water table are the most important factors

considered in evaluating the potential for frost action. It

is assumed that the soil is not insulated by vegetation

or snow and is not artificially drained. Silty and highly

structured, clayey soils that have a high water table in

winter are the most susceptible to frost action. Well

drained, very gravelly, or very sandy soils are the least

susceptible. Frost heave and low soil strength during

thawing cause damage to pavements and other rigid

structures.

Risk of corrosion pertains to potential soil-induced

electrochemical or chemical action that corrodes or

weakens uncoated steel or concrete. The rate of

corrosion of uncoated steel is related to such factors

as soil moisture, particle-size distribution, acidity, and

electrical conductivity of the soil. The rate of corrosion

of concrete is based mainly on the sulfate and sodium

content, texture, moisture content, and acidity of the

soil. Special site examination and design may be

needed if the combination of factors results in a severe

hazard of corrosion. The steel or concrete in

installations that intersect soil boundaries or soil layers

is more susceptible to corrosion than the steel or

concrete in installations that are entirely within one

kind of soil or within one soil layer.

For uncoated steel, the risk of corrosion, expressed

as low, moderate, or high, is based on soil drainage

class, total acidity, electrical resistivity near field

capacity, and electrical conductivity of the saturation

extract.

For concrete, the risk of corrosion also is expressed

as low, moderate, or high. It is based on soil texture,

acidity, and amount of sulfates in the saturation

extract.

combination with needed cultural and

management practices. In a good conservation

cropping system, the soil-improving crops and

is called the culmination of the mean annual

increment.

generally a terrace, built to protect downslope

areas by diverting runoff from its natural course.

Drainage class (natural). Refers to the frequency and

duration of wet periods under conditions similar to

those under which the soil formed. Alterations of

beneath a glacier.

Ground water. Water filling all the unblocked pores of

the material below the water table.

Gully. A miniature valley with steep sides cut by

running water and through which water ordinarily

runs only after rainfall. The distinction between a

gully and a rill is one of depth. A gully generally is

an obstacle to farm machinery and is too deep to

be obliterated by ordinary tillage; a rill is of lesser

depth and can be smoothed over by ordinary

tillage.

Hard bedrock. Bedrock that cannot be excavated

except by blasting or by the use of special

equipment that is not commonly used in

construction.

Hard to reclaim (in tables). Reclamation is difficult

after the removal of soil for construction and other

These crops return large amounts of organic

matter to the soil.

Hill. A natural elevation of the land surface, rising as

much as 1,000 feet above surrounding lowlands,

commonly of limited summit area and having a

well defined outline; hillsides generally have

slopes of more than 15 percent. The distinction

between a hill and a mountain is arbitrary and is

dependent on local usage.

Horizon, soil. A layer of soil, approximately parallel to

the surface, having distinct characteristics

produced by soil-forming processes. In the

identification of soil horizons, an uppercase letter

represents the major horizons. Numbers or

lowercase letters that follow represent

subdivisions of the major horizons. An explanation

of the subdivisions is given in the “Soil Survey

Manual.” The major horizons of mineral soil are as

follows:

O horizon.—An organic layer of fresh and

decaying plant residue.

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
214 Soil Survey of

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.

Humus. The well decomposed, more or less stable

part of the organic matter in mineral soils.

Hydrologic soil groups. Refers to soils grouped

according to their runoff potential. The soil

properties that influence this potential are those

that affect the minimum rate of water infiltration on

a bare soil during periods after prolonged wetting

when the soil is not frozen. These properties are

depth to a seasonal high water table, the

infiltration rate and permeability after prolonged

wetting, and depth to a very slowly permeable

layer. The slope and the kind of plant cover are not

considered but are separate factors in predicting

runoff.

Igneous rock. Rock formed by solidification from a

molten or partially molten state. Major varieties

include plutonic and volcanic rock. Examples are

andesite, basalt, and granite.

Illuviation. The movement of soil material from one

horizon to another in the soil profile. Generally,

Infiltration rate. The rate at which water penetrates

the surface of the soil at any given instant,

can be limited by the infiltration capacity of the

soil or the rate at which water is applied at the

surface.

Intake rate. The average rate of water entering the

soil under irrigation. Most soils have a fast initial

rate; the rate decreases with application time.

Therefore, intake rate for design purposes is not a

constant but is a variable depending on the net

irrigation application. The rate of water intake, in

inches per hour, is expressed as follows:

Less than 0.2 ............................................... very low

0.2 to 0.4 .............................................................. low

0.4 to 0.75 ......................................... moderately low

0.75 to 1.25 ................................................ moderate

1.25 to 1.75 ..................................... moderately high

1.75 to 2.5 .......................................................... high

More than 2.5 ............................................. very high

that flows for prolonged periods only when it

receives ground-water discharge or long,

continued contributions from melting snow or other

surface and shallow subsurface sources.

by small earth ridges called border dikes, or

borders.

Controlled flooding.—Water is released at

intervals from closely spaced field ditches and

distributed uniformly over the field.

Corrugation.—Water is applied to small, closely

spaced furrows or ditches in fields of closegrowing crops or in orchards so that it flows in only

one direction.

Drip (or trickle).—Water is applied slowly and

under low pressure to the surface of the soil or

into the soil through such applicators as emitters,

porous tubing, or perforated pipe.

an unconfined clod as moisture content is

decreased from a moist to a dry state. Linear

potential of soils. It is an expression of the volume

change between the water content of the clod at

1

/3- or 1/10-bar tension (33kPa or 10kPa tension)

and oven dryness. Volume change is influenced by

the amount and type of clay minerals in the soil.

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.

Subsidence. The potential decrease in surface

elevation caused by the drainage of wet soils that

have organic layers or semifluid, mineral layers.

Subsidence is attributed to (1) shrinkage as the

material dries, (2) consolidation resulting from the

loss of ground-water buoyancy, (3) compaction

resulting from tillage or manipulation, (4) wind

erosion, (5) burning, and (6) biochemical

oxidation.

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.

Substratum. The part of the soil below the solum.
220

Subsurface layer. Any surface soil horizon (A, E, AB,

or EB) below the surface layer.

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.”

Surface soil. The A, E, AB, and EB horizons,

considered collectively. It includes all subdivisions

of these horizons.

Swale. A slight depression in the midst of generally

level land. On an undulating ground moraine, a

shallow depression resulting from uneven glacial

deposition.

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. A belt of thick glacial drift that

generally marks the termination of important

glacial advances.

Terrace. 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 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 (geologic). An old alluvial plain, ordinarily

flat or undulating, bordering a river, a lake, or the

sea.

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 (in tables). Otherwise suitable soil material

that is too thin for the specified use.

Till. Unsorted, nonstratified glacial drift consisting of

clay, silt, sand, and boulders transported and

deposited by glacial ice.

Till plain. An extensive area of nearly level to

undulating soils underlain by glacial till.

Tilth, soil. The physical condition of the soil as

related to tillage, seedbed preparation, seedling

emergence, and root penetration.

Toeslope. The position that forms 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 closeddepression floors.

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.

Understory. Any plants in a forest community that

grow to a height of less than 5 feet.

Upland (geology). Land at a higher elevation, in

general, than the alluvial plain or stream terrace;

land above the lowlands along streams.

Variegation. Refers to patterns of contrasting colors

assumed to be inherited from the parent material

rather than to be the result of poor drainage.

Weathering. All physical and chemical changes

produced in rocks or other deposits at or near the

earth’s surface by atmospheric agents. These

changes result in disintegration and

decomposition of the material.

Well graded. Refers to soil material consisting of

coarse grained particles that are well 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.

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.

Table 20a.--Construction Materials

(The information in this table indicates the dominant soil condition but

 does not eliminate the need for onsite investigation. The ratings

 given for the thickest layer are for the thickest layer above the

 bottom layer. The numbers in the value columns range from 0.00 to

 0.99. The greater the value, the greater the likelihood that the

 bottom layer or thickest layer of the soil is a source of sand or

 gravel. See text for further explanation of ratings in this table.)

been removed and used, without crushing, as a source of sand or

gravel. Typically 0.2 acre to 2.0 acres.

GPI

Gravelly spot A spot where the surface layer has more than 35 percent, by volume,

rock fragments that are mostly less than 3 inches in diameter in an

area that has less than 15 percent rock fragments. Typically 0.2 acre

to 2.0 acres.

GRA
Name Description Label

Gray spot A spot in which the surface layer is gray in areas where the

subsurface layer of the named soils in the surrounding map unit are

darker. Typically 0.25 acre to 2.0 acres.

GSP

Gully A small channel with steep sides cut by running water through which

water ordinarily runs only after a rain or after melting of snow or ice.

It generally is an obstacle to wheeled vehicles and is too deep to be

obliterated by ordinary tillage.

GUL

Iron bog An accumulation of iron in the form of nodules, concretions, or soft

masses on the surface or near the surface of soils. Typically 0.2 acre

to 2.0 acres.

BFE

Landfill An area of accumulated waste products of human habitation, either

above or below natural ground level. Typically 0.2 acre to 2.0 acres.

LDF

Levee An embankment that confines or controls water, especially one built

along the banks of a river to prevent overflow onto lowlands.

LVS

Marsh or swamp A water-saturated, very poorly drained area that is intermittently or

permanently covered by water. Sedges, cattails, and rushes are the

dominant vegetation in marshes, and trees or shrubs are the dominant

vegetation in swamps. Typically 0.2 acre to 2.0 acres.

MAR

Mine or quarry An open excavation from which soil and underlying material have

been removed and in which bedrock is exposed. Also denotes surface

openings to underground mines. Typically 0.2 acre to 2.0 acres.

MPI

Mine subsided area An area that is lower than the soils in the surrounding map unit

because of subsurface coal mining. Typically 0.25 acre to 3.0 acres.

MSA

Miscellaneous water A small, constructed body of water that is used for industrial,

sanitary, or mining applications and that contains water most of the

year. Typically 0.2 acre to 2.0 acres.

MIS

Muck spot An area that occurs within an area of poorly drained or very poorly

drained soil and that has a histic epipedon or an organic surface

layer. The symbol is used only in map units consisting of mineral

soil. Typically 0.2 acre to 2.0 acres.

MUC

Oil brine spot An area of soil that has been severely damaged by the accumulation

of oil brine, with or without liquid oily wastes. The area is typically

barren but may have a vegetative cover of salt-tolerant plants.

Typically 0.2 acre to 2.0 acres.

OBS

Perennial water A small, natural or constructed lake, pond, or pit that contains water

most of the year. Typically 0.2 acre to 2.0 acres.

WAT
Name Description Label

Rock outcrop An exposure of bedrock at the surface of the earth. Not used where

the named soils of the surrounding map unit are shallow over

bedrock or where “Rock outcrop” is a named component of the map

unit. Typically 0.2 acre to 2.0 acres.

ROC

Saline spot An area where the surface layer has an electrical conductivity of 8

mmhos/cm-l more than the surface layer of the named soils in the

surrounding map unit. The surface layer of the surrounding soils has

an electrical conductivity of 2 mmhos/cm-l or less. Typically 0.2

acre to 2.0 acres.

SAL

Sandy spot A spot where the surface layer is loamy fine sand or coarser in areas

where the surface layer of the named soils in the surrounding map

unit is very fine sandy loam or finer. Typically 0.2 acre to 2.0 acres.

SAN

Severely eroded spot 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. Typically 0.2 acre to 2.0

acres.

ERO

Short steep slope A narrow area of soil having slopes that are at least two slope classes

steeper than the slope class of the surrounding map unit.

SLP

Sinkhole A closed depression formed either by solution of the surficial rock or

by collapse of underlying caves. Typically 0.2 acre to 2.0 acres.

SNK

Slide or slip 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.

Typically 0.2 acre to 2.0 acres.

SLI

Sodic spot 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. Typically 0.2 acre to 2.0

acres.

SOD

Spoil area A pile of earthy materials, either smoothed or uneven, resulting from

human activity. Typically 0.2 acre to 2.0 acres.

acres.

STN

Unclassified water A small, natural or manmade lake, pond, or pit that contains water,

of an unspecified nature, most of the year. Typically 0.2 acre to 2.0

acres.

UWT
Name Description Label

stones. Typically 0.2 acre to 2.0 acres.

STV

Wet depression A shallow, concave area within an area of poorly drained or very

poorly drained soils in which water is ponded for intermittent

periods. The concave area is saturated for appreciably longer periods

of time than the surrounding soil. Typically 0.2 acre to 2.0 acres.

WDP

Wet spot A somewhat poorly drained to very poorly drained area that is at

least two drainage classes wetter than the named soils in the
