BUILDING SITE DEVELOPMENT
Endnote -- BUILDING SITE DEVELOPMENT
This report shows the degree and kind of soil limitations that affect shallow excavations, dwellings with and without
basements, small commercial buildings, local roads and streets, and lawns and landscaping. The limitations are
"Slight", "Moderate", or "Severe". The limitations are considered "Slight" if soil properties and site features are
generally favorable for the indicated use and limitaions are minor and easily overcome; "Moderate" if soil properties
or site features are not favorable for the indicated use and special planning, design, or maintenance is needed to
r' -come or minimize the limitations; and "Severe"" if soil properties or site features are so unfavorable or so
.cult to overcome that special design, significant increases in construction costs, and possibly increased
maintenance are required. Special feasibility studies may be required where the soil limitations are severe.
SHALLOW EXCAVATIONS are trenches or holes dug to a maximum depth of 5 or 6 feet for basements, graves, utility lines,
open ditches, and other purposes. The ratings are based on soil properties, site features, and observed performance of
the soils. The ease of digging, filling, and compacting is affected by the depth to bedrock, a cemented pan, or a very
firm dense layer; stone content; soil texture; and slope. The time of the year that excavations can be made is
affected by the depth to a seasonal high water table and the susceptibility of the soil to flooding. The resistance of
the excavation walls or bands to sloughing or caving is affected by soil texture and the depth to the water table.
DWELLINGS AND SMALL COMMERCIAL BUILDINGS are structures built on shallow foundations on undisturbed soil. The load
limit is the same as that for single-family dwellings no higher than three stories. Ratings are made for small
commercial buildings without basements, for dwellings with basements, and for dwellings without basements. The ratings
are based or: soil properties, site features, and observed performance of the soils. A high water table, depth to bedrock
or to a cemented pan, large stones, slope, and flooding affect the ease of excavation and construction. Landscaping
and grading that require cuts and fills of more than 5 or 6 feet are not considered.
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 stabilized soil material, and a
flexible or rigid surface. Cuts and fills are generally properties, site features, and observed performance of the
soils. Depth to bedrock or to a cemented pan, a high water table, flooding, large stones, and slope affect the ease of
excavating and grading. Soil strength (as inferred from the engineering classification of the soil), shrink-swell
potential, frost action potential, and depth to a high water table affect the traffic-supporting capacity.
LAWNS AND LANDSCAPING require soils on which turf and ornamental trees and shrubs can be established and
tained. The ratings are based on soil properties, site features, and observed performance of the soils. Soil
_.tion, a high water table, depth to bedrock or to a cemented pan, the available water capacity in the upper 40
inches, and the content of salts, sodium, and sulfidic materials affect plant growth. Flooding, wetness, slope,
stoniness, and the amount of sand, clay, or organic matter in the surface layer affect trafficability after vegetation
is established.

CHEMICAL PROPERTIES OF THE SOILS
Endnote -- CHEMICAL PROPERTIES OF THE SOILS
This report shows estimates of some characteristics and features that affect soil behavior.
These estimates are given for the major layers of each soil in the survey area. The estimates
are based or field observations and on test data for these and similar sails.
CLAY as a soil separate consists of mineral soil particles that are less than 0,002
m"'imeter in diameter. In this report, the estimated clay content of each major soil layer
even 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, and 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.
CATION EXCHANGE CAPACITY (CEC) is the total amount of cations held in a soil in such
a way that they can be removed only by exchanging with another cation in the natural soil
solution. CEC is a measure of the ability of a soil to retain cations, some of which are
plant nutrients. Soils with low CEC hold few cations and may require more frequent
applications of fertilizers than soils with high CEC. Soils with high CEC have the potential
to retain cations, thus reducing the possibility of pollution of ground water.
SOIL REACTION is a measure of acidity or alkalinity and is expressed as a range in pH
values. The range in pH of each major 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.
CALCIUM CARBONATE is the percentage by weight of calcium carbonate in the fine-earth
material, less than 2 millimeters in size.
GYPSUM is the percentage by weight of hydrated calcium sulfates 20 millimeters or
smaller in size, in the soil.
.,LAITY is a measure of soluble salts in the soil at saturation. It is expressed
as the electrical conductivity of the saturation extract, in millimhos per centimeter
at 25 degrees C. Estimates are based on field and laboratory measurements at representative
sites of nonirrigated sols.
The salinity of irrigated soils is affected by the quality of the irrigation water
and by the freouencv of water aoolication. Hence. the salinity of soils in individual fields
a soil for crop production, the stability of soil if used as construction material, and
the potential of the soil to corrode metal r :oncrete.
SODIUM ADSORPTION RATIO (SAR) expresses the relative activity of sodium ions in
exchange reactions in the soil. SAR is a measure of the amount of sodium relative to
calcium and magnesium in the water extract from saturated soil paste.

Endnote -- PHYSICAL PROPERTIES OF SOILS
This report shows estimates of some characteristics and features that affect soil behavior. These estimates
are given for the major layers of each soil in the survey area. The estimates are based on field observations
and on test data for these and similar soils.
CLAY as a soil separate consists of mineral soil particles that are less than 0.002 millimeter in diameter.
T- 'his report, the estimated clay content of each major soil layer is given as a percentage, by weight, of the
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, the moisture content at 1/3 bar moisture tension. Weight is determined after
drying the soil at 105 degrees C. In this report, the estimated moist bulk density of each major 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. A bulk density of mare than 1.6 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 refers to the ability of a soil to transmit water or air, The estimates indicate the
rate of downward movement of water 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, septic tank absorption fields. and construction where the rate of
water movement under saturated conditions affects behavior.
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 major soil layer.
The capacity varies, depending on soil properties that affect the retention of water and the depth of the root
zone. The most important properties are the content of organic matter, soil texture, bulk density, and soil
cture. Available water capacity is an important factor in the choice of plants or crops to be grown and in
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.
SHRINK-SWELI POTENTIAL is the potential for volume change in a soil with a loss or gain of moisture. Volume
change occurs mainly because of the interaction of clay minerals with water and varies with the amount and type
of clay minerals in the soil. The size of the load on the soil and the magnitude of the change in soil moisture
rnnt.ent influence the mount of swellina of soils in place. Laboratory measurements of swelling of undisturbed
clay minerals in the soil and on measurements of similar soils. If the shrink-swell potential is rated moderate
to very high, shrinking and swelling can cat iamage to buildings, roads, and other struct Special design
is often needed. Shrink-swell potential classes are based on the change in length of an uncuofined clod as
moisture cortent is increased from air-dry to field capacity. The change is based on the soil fraction less
than 2 millimeters in diameter. The classes are "Low," a change of less than 3 percent; "Moderate," 3 to 6
percent; an,1 "High," more than 6 percent. "Very high," greater than 9 percent, is sometimes used.

ORGANIC MATTER is the plant and animal residue in the soil at various stages of decomposition. In report J,
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 or increased by
returning crop residue to the soil. Organic matter affects the available water capacity, infiltration rate, and
tilth. It is a source of nitrogen and other nutrients for crops.
.ON FACTOR K indicates the susceptibility of the whole soil (including rocks and rock fragments) to
sheet and rill erosion by water. Factor K is one of six factors used in the Universal Soil Loss Equation (USLE)
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 (up to 4 percent) and on soil
structure and permeability, Values of K range from 0.05 to 0.69. The higher the value, the more susceptible
the soil is to sheet and rill erosion by water.
EROSION FACTOR Kf is like EROSION FACTOR K but it is for the fine-earth fraction of the soil. Rocks and
rock fragments are not considered.
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 resistance to wind
erosion in cultivated areas. The groups indicate the susceptibility of soil to wind erosion. Soils are grouped
according to the following distinctions:
1. Coarse sands, sands, fine sands, and very fine sands.
These soils are generally not suitable for crops. They are
extremely erodible, and vegetation is difficult to
establish.
2. Loamy coarse sands, loamy sands, loamy fine sands, loamy
very fine sands, and sapric soil material. These soils are
very highly erodible. Crops can be grown if intensive
measures to control wind erosion are used.
3. Coarse sandy loams, sandy loans, fine sandy loams, and
very fine sandy loans. These soils are highly erodible.
Crops can be grown if intensive measures to control wind
erosion are used.

7. Silts, noncalcareous silty clay loans that are less than
35 percent clay, and fibric soil material. These soils are
very slightly erodible. Crops can be grown if ordinary
measures to control wind erosion are used.
8. Soils that are not subject to wind erosion because of
coarse fragments on the surface or because of surface
wetness.
The WIND ERDDIBILITY INDEX is used in the wind erosion equation (WEQ). The index number indicates the
amount of soil lost in tons per acre per year. The range of wind erodibility index numbers is 0 to 300.

WATER FEATURES
Endnote -- MATER FEATURES
This report gives estimates of various soil water features. The estimates are used in land use planning that involves
engineering considerations.
Hydrologic soil groups are used to estimate runoff from precipitation. Soils not protected by vegetation are
assigned to one of four groups. They are grcuped according to the infiltration of water when the soils are thoroughly
' and receive precipitation from long-duration storms. The four hydrologic soil groups are:
Group " A". Soils having a high infiltration rate (low
runoff potential) when thoroughly wet, These consist mainly
of deep, well drained to excessively grained sands or
gravelly sands. These soils have a high rate of water
transmission.
Group "B". Soils having a moderate ir•filtration 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 permanent 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.
If a soil is assigned to two hydrologic groups in this report, the first letter is for drained areas and the second
is for undrained areas. Flooding, the temporary inundation of an area, is 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, nor is water in swamps and marshes. This report gives the frequency and duration of flooding and
the time of year when flooding is most likely. Frequency, duration, and probable dates of occurrence are estimated.

"Rare" that it is unlike'y but possible under unusual weather conditions; "Occasional" that it occurs, on the
average, once or less in 2 years; and "Fruit " that it occurs, on the average, more than in 2 years.
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. 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;
,bsence of distinctive horizons that form in soils that are not subject to flooding. Also considered are local
i,„urmation 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 food-prone areas at specific flood frequency levels.
High water table (seasonal) is the highest level of a saturated zone in the soil in most years. The depth to a
seasonal high water table applies to undrained soils. The estimates are based mainly on the evidence of a saturated
namely grayish colors or mottles in the soil. Indicated in this report are the depth to the seasonal high
table; the kind of water table, that is, "Apparent", "Artesian", or "Perched"; and the months of the year that
the water table commonly is high. A water table that is seasonally high for less than 1 month is not indicated in
this report.
An "Apparent" water table is a thick zone of free water in the soil. It is indicated by the level at which water
stands in an uncased borehole after adequate time is allowed for adjustment in the surrounding soil.
An "Artesian" water table exists under a hydrostatic beneath an impermeable layer. When the impermeable layer has been
penetrated by a cased borehole, the water rises. The final level of the water in the cased borehole is characterized as
an artesian water table.
A "Perched" water table is water standing above an unsaturated zone. In places an upper, or "Perched", water
table is separated from a lower one by a dry zone. Only saturated zones within a depth of about 6 feet are
indicated.
Ponding is standing water in a closed depression. The water is removed only by deep percolation, transpiration,
evaporation, or a combination of these processes.
This report gives the depth and duration of ponding and the time of year when ponding is most likely. Depth, duration,
and probable dates of occurrence are estimated.
Depth is expressed as the depth of ponded water in feet above the soil surface. 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. The
information is based on the relation of each soil on the landscape to historic ponding and on local information about
the extent and levels of ponding.

SOIL FEATURES
Endnote -- SOIL FEATURES
This report gives estimates of various soil features. The estimates are used in land use planning that involves
engineering considerations.
Depth to bedrock is given if bedrock is within a depth of 5 feet. The depth is based on many soil borings and on
observations during soil mapping. The rock is either "Soft" or "Hard". If the rock is "Soft" or fractured, excavations
be made with trenching machines, backhoes, or small rippers. If the rock is "Hard" or massive, blasting or
iai equipment generally is needed for excavation.
Cemented pans are cemented or indurated subsurface layers within a depth of 5 feet. Such pans cause difficulty in
excavation. Pans are classified as "Thin" or "Thick". A "Thin" pan is less than 3 inches thick if continuously
indurated or less than !8 inches thick if discontinuous or fractured. Excavations can be made by trenching machines,
backhoes, or small rippers. A "Thick" pan is more than 3 inches thick if continuously indurated or more than 18
inches thick if discontinuous or fractured. Such a pan is so thick or massive that blasting or special equipment is
needed in excavation.
Subsidence is the settlement of organic soils or of saturated mineral soils of very low density. Subsidence
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. This report shows the expected initial
subsidence, which usually is a result of drainage, and total subsidence, which usually is a result of oxidation. Not
shown in the report is subsidence caused by an imposed surface load or by the withdrawal of ground water throughout
an extensive area as a result of lowering the water table.
Potential 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
f"ost action. Well drained, very gravelly, or very sandy soils are the least susceptible. Frost heave and low soil
strength during thawing cause damage mainly to pavements and other rigid structures.
k of corrosion pertains to potential soil-induced electrochemical or chemical action that dissolves or weakens
�oated 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 creates a severe corrosion environment. The steel
installations that inte-sect soil boundaries or soil layers is more susceptible to corrosion than steel in
installations that are entirely within one kind of soil or within one soil layer. For uncoated steel, the risk of

This report shows the degree and kind of soil limitations that affect septic tank absorption fields, sewage lagoons,
and sanitary landfills. The limitations are considered "Slight" if soil properties and site features generally are
favorable for the indicated use and limitations are minor and easily overcome; "Moderate" if soil properties or site
features are not favorable for the indicated use and special planning, design, or maintenance is needed to overcome or
minimize the limitations; and "Severe" if soil properties or site features are so unfavorable or so difficult to overcome
t' ` special design, significant increases in construction costs, and possibly increased maintenance are required.
report also shows the suitability of the soils for use as daily cover for landfills. A rating of "Good" indicates
that soil properties and site features are favorable for the use and good performance and low maintenance can be
expected; "Fair" indicates that soil properties and site features are moderately favorable for the use and one or
more soil properties or site features make the soil less desirable than the soils rated "Good"; and "Poor" indicates
that one or more soil properties or site features are unfavorable for the use and overcoming the unfavorable
properties requires special design, extra maintenance, or costly alteration.
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 to 72 inches is evaluated. The
ratings are base on soil properties, site features, and observed performance of the soils. Permeability, a high
water table, depth to bedrock or to a cemented pan, and flooding affect absorption of the effluent. Large stones
and bedrock or a cemented pan interfere with installation. Unsatisfactory performance of septic tank absorption fields,
including excessively slow absorption of effluent, surfacing of effluent, and hillside seepage, can affect public health.
Groundwater can be polluted if highly permeable sand and gravel or fractured bedrock is less than 4 feet below the
base of the absorption field, if slope is excessive, or if the water table is near the surface. There must be
unsaturated soil material beneath the absorption field to filter the effluent effectively. Many local ordinances
require that this material be of a certain thickness.
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. Lagoons
generally are designed to hold the sewage within a depth of 2 to 5 feet. Nearly impervious soil material for the lagoon
floor and sides is required to minimize seepage and contamination of ground water. This report gives ratings for
the natural soil that makes up the lagoon floor. The surface layer and, generally, 1 or 2 feet of soil material
below the surface layer are excavated to provide material for the embankments. The ratings are based on soil
properties, site features, and observed performance of the soils. Considered in the ratings are slope, permeability, a
' water table, depth :o bedrock or to a cemented pan, flooding, large stones, and content of organic matter.
�... ssive seepage due to rapid permeability of the soil or a water table that is high enough to raise the level of sewage
in the lagoon causes a lagoon to function unsatisfactorily. Pollution results if seepage is excessive 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.

groundwater pollution. Ease of excavation and revegetation need to be considered. The ratings in this report are based

on soil properties, site features, and observed performance of the soils. Permeability, depth to bedrock or to a
cemented pan, a high water table, slope, and flooding affect both types of landfill. Texture, stones and boulders,
highly organic layers, soil reaction, and content of salts and sodium affect trench type landfills. Unless otherwise
stated, the ratings apply only to that part of the soil within a depth of about 6 feet. For deeper trenches, a
limitation rate "Slight" or "Moderate" may not be valid. Onsite investigation is needed.
( COVER FOR LANDFILL is the soil material that is used to cover compacted solid waste in an area type sanitary
landfill. The soil material is obtained offsite, transported to the landfill, and spread over the waste.
Soil texture, wetness, coarse fragments, and slope affect the ease of removing and spreading the material during wet
and dry periods. Loamy or silty soils that are free of large stones or excess gravel are the best cover for a
landfill. Clayey soils may be sticky or cloddy and are difficult to spread; sandy soils are subject to soil
blowing. 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 final cover for a
landfill should be suitable for plants. The surface layer generally has the best workability, more organic matter than
the rest of the profile, and the best potential for plants. Material from the surface layer should be stockpiled for use
as the final. cover.
