1.1 INTRODUCTION
The State of Minnesota requires owners and operators of all construction sites disturbing one or more
acres of land to apply for and comply with a construction storm water general permit; Minnesota's
General Storm Water Permit for Construction Activity (Permit MNRI 0000 1) issued by the Minnesota
Pollution Control Agency (MPCA). The goal of this permit is to reduce the amount of polluted storm
water runoff that flows into Minnesota's waters. A reduction in pollution occurs when management
practices are implemented to prevent and reduce the erosion on construction sites.
The Storm Water Pollution Prevention Plan (SWPPP) was prepared to comply with the Permit. The
purpose of the SWPPP is to:
· identify potential pollutant sources that may affect the quality of discharges associated with
construction activity;
· identify non-storm water discharges;
· design the use and placement of Best Management Practices (BMPs) to effectively prohibit the
entry of pollutants from the construction site into the storm drain system during construction.
Erosion and sediment source control BMPs must be considered for both active and inactive
(previously disturbed) construction areas. BMPs for wind erosion and dust control are also
included.
· modify the SWPPP as the project progresses and as conditions warrant
This SWPPP is prepared specifically for Lakeside 4th Addition in Chanhassen.

1.3 SWPPP Amendments
The Permittee(s) must amend the SWPPP as necessary to include additional
requirements, such as additional or modified BMPs, designed to correct problems
identified or address situations whenever:
1 There is a change in design, construction, operation, maintenance, weather or
seasonal conditions that has a significant effect on the discharge of pollutants to
surface waters or underground waters;
2 Inspections or investigations by site operators, local, state or federal officials indicate
the SWPPP is not effective in eliminating or significantly minimizing the discharge
of pollutants to surface waters or underground waters or that the discharges are
causing water quality standard excesses (e.g. nuisance conditions as defined in Minn.
R. 7050.0210, subp. 2); or
3 The SWPPP is not achieving the general objectives of minimizing pollutants in
storm water discharges associated with construction activity, or the SWPPP is not
consistent with the terms and conditions of this permit.
4 At any time after permit coverage is effective, the MPCA may determine that the
project's storm water discharges may cause, have reasonable potential to cause, or
contribute to non-attainment of any applicable water quality standard, or that the
SWPPP does not incorporate the applicable requirements in Part III.A.9, Discharges
to Impaired Waters and TMDLs. If MPCA makes such determination(s) or any of
the determinations in Parts III.A.5.a.-.c., MPCA will notify the Permittee(s) in
writing. In response, the Permittee(s) must develop a supplemental BMP action plan
or appropriate SWPPP amendments describing SWPPP modifications to address the
identified concerns and submit information requested by MPCA, which may include
an individual permit application. If MPCA's written notification requires a response,
failure to respond within the specified timeframe constitutes a permit violation.
Amendments to the SWPPP shall be attached, documented and certified in Appendix D
by the SWPPM. Each Amendment shall include:
· Assigned a consecutive log in number and attached to the SWPPP in appendix D.
· Table in appendix D will be filled out with:
i) Amendment Number
ii) Summary of Amendment or revision
iii) Date of revision
iv) Preparer Name and title
v) Approved by the Owner and/or Contractor
Throughout routine inspections and maintenance it may be determined that erosion and sediment
control measures are not performing adequately and need to be amended. Furthermore, during
inclement weather it may be determined that certain erosion control measures such as silt fence
may not be feasible to install and adequately maintain. The following procedures shall be
followed to amend the SWPPP:
· Document the recommended SWPPP modification in the Inspection and
Maintenance Log

4. Erosion Control Practices
4.1 Temporary Erosion Control Practices
Erosion control, also referred to as soil stabilization, consists of source control measures that are
designed to prevent soil particles from detaching and becoming transported in storm water
runoff. Erosion control BMPs, protect the soil surface by covering and/or binding soil particles.
This project will incorporate erosion control measures required by the contract documents, and
other measures selected by the Contractor. Implementation and locations of temporary erosion
control BMPs are shown on the Grading and Erosion Control Plans in APPENDIX Band/or
described in this section:
· Limits of grading activity will be field located to preserve existing vegetation where
required and when feasible.
· Perimeter erosion control fence will be installed prior to any grading activities.
· The construction shall be phased to limit exposed soils during grading. Each phase must
be restored per the grading and erosion control plans as work is completed. All exposed
soils must be stabilized as soon as possible but in no case later than 7days after
construction activity has ceased.
· Wood fiber blanket will be installed on all slopes greater then 4: 1.
· All temporary stockpiles will be surrounded by erosion control fence and temporary
seeded per the grading and erosion control plan, if the stockpile is to remain for more
then 7 days.
· Apply temporary erosion control to remaining active and non-active areas as required by
the Permit and the contract documents. Reapply as necessary to maintain effectiveness.

Sufficient erosion control materials will be maintained on-site to allow implementation in
conformance with Permit requirements and described in this SWPPP. This includes
implementation requirements for active areas and non-active areas.
4.2 Final Stabilization
Permanent turf establishment will consist of:
· Spread of stockpiled topsoil to a minimum depth of six inches
. Smooth topsoil using horizontal tracking to the slope direction.
. Seed, fertilize and mulch per the specifications.
· Maintain all temporary sediment and erosion control practices until Final Stabilization is
established.
· Remove all temporary synthetic and structural erosion control within 30 days offma1
stabilization.
.
Final Stabilization requires the following:
1. Final Stabilization requires that all soil disturbing activities at the site have been completed and

Erosion Control for New Homeowners sheet.
b. For multi-family developments, ftnal stabilization has been completed when turfhas been
established for the lot.
c. Near the completion of the development, all storm ponds will be clean of unstable sediment.
d. When the complete development is at Final Stabilization, the Superintendent is to notify the
Land Department to submit to the MPCA for a Notice of Termination.
5. Sediment Control Practices
Sediment controls are structural measures that are intended to complement and enhance the selected
erosion control measures and reduce sediment discharges from active construction areas. Sediment
controls are designed to intercept and settle out soil particles that have been detached and transported by
the force of water. This project will incorporate sediment control measures required by the contract
documents, and other measures selected by the Owner/Developer/Contractor.
Sufficient quantities of temporary sediment control materials will be maintained on-site
throughout the duration of the project, to allow implementation of temporary sediment controls
in the event of predicted rain, and for rapid response to failures or emergencies, in conformance
with other Permit requirements and as described in this SWPPP. Implementation and locations of
temporary sediment control BMPs are shown on the Grading and Erosion Control Plans in
APPENDIX B and/or described in this section:
. Rock construction entrance.
. Temporary sediment control basins with stabilized outlet
. All stockpile material shall be properly contained and protected.
. All sediment tracked on to streets shall be removed within 24 hours of detection.
6. Special or Impaired Waters Additional BMP's

are as follows:
1. All exposed soil areas shall be stabilized within 7 days after construction activity in that
portion of the site has temporarily or permanently ceased.
7. Pollution Prevention Measures
7.1 Solid Waste
Collected sediment, asphalt and concrete millings, floating debris, paper, plastic, fabric, construction and
demolition debris and other wastes must be disposed of properly and must comply with MPCA disposal
requirements.
Solid Waste Management will be implemented to minimize storm water contact with waste materials and
prevent waste discharges. Solid wastes will be loaded directly into trucks for off-site disposal. When on-
site storage is necessary, solid wastes will be stored in watertight dumpsters in the general storage area of

the Contractors yard. Cement and asphalt rubble will be stockpiled in the general storage area and will be
surrounded with sediment controls (i.e., Sandbag Barrier) and covered when necessary. Solid waste,
including rubble stockpiles, will be removed and disposed off-site at least bi-weekly.
Hazardous wastes will be stored in the shipping containers or covered containment area discussed above
for materials storage. Hazardous wastes will be appropriate and clearly marked containers and segregated
from other non-waste materials.
7.2 Hazardous Waste
Hazardous Materials: Oil, gasoline, paint and any hazardous substances must be properly stored,
including secondary containment, to prevent spills, leaks or other discharge. Restricted access to storage
areas must be provided to prevent vandalism. Storage and disposal of hazardous waste must be in
compliance with MPCA regulations.
No hazardous wastes are anticipated to be stored on the site.
Several types of vehicles and equipment will be used on-site throughout the project, including
motor graders, scrapers, excavators, loaders, paving equipment, rollers, trucks and trailers, backhoes,
forklifts, generators, compressors, and traffic control equipment. A paved temporary fueling area will be
constructed in the Contractor's yard. All self-propelled vehicles will be fueled off-site or at the temporary
fueling area. Fuel trucks, each equipped with absorbent spill clean-up materials, will be used for all on-
site fueling, whether at the temporary fueling area or for mobile fueling elsewhere on the site. Drip pans
will be used for all mobile fueling. The fueling truck will be will not be parked onsite overnight
Drip pans or absorbent pads will be used for all vehicle and equipment maintenance activities
that involve grease, oil, solvents, or other vehicle fluids. All vehicle maintenance and mobile fueling
operations will be conducted at least 50 feet away from operational inlets and drainage facilities and on a
level graded area.
7.3 Truck Washing and Construction Vehicles
No vehicle washing or will occur on site.
7.4 Concrete Washout
a. Small mortar mixers may washout on the lot if adequate impermeable concrete washout pit is
established
b. Ready-mix truck and concrete pumps self contained wash out specifications:
. Ready-mix truck drivers wash out into a chute bucket
Slurry water from bucket is pumped back into mixer drum
7.5 Spill Prevention Plan
These procedures and practices are implemented to prevent and control spills in a manner that
minimizes or prevents the discharge of spilled material to the drainage system or watercourses.
7.5.1 Vehicle and Equipment Maintenance
. If maintenance must occur onsite, use a designated area and a secondary containment,
located away from drainage courses, to prevent the runoff of storm water and the runoff
of spills.
· Regularly inspect onsite vehicles and equipment for leaks and repair immediately
. Check incoming vehicles and equipment (including delivery trucks, and employee and
subcontractor vehicles) for leaking oil and fluids. Do not allow leaking vehicles or
equipment onsite.

. Always use secondary containment, such as a drain pan or drop cloth, to catch spills or
leaks when removing or changing fluids.
· Place drip pans or absorbent materials under paving equipment when not in use.
· Use absorbent materials on small spills rather than hosing down or burying the spill.
Remove the absorbent materials promptly and dispose of properly.
. Promptly transfer used fluids to the proper waste or recycling drums. Don't leave full
drip pans or other open containers lying around
· Oil filters disposed of in trashcans or dumpsters can leak oil and pollute storm water.
Place the oil filter in a funnel over a waste oil-recycling drum to drain excess oil before
disposal. Oil filters can also be recycled. Ask the oil supplier or recycler about recycling
oil filters.
· Store cracked batteries in a non-leaking secondary container. Do this with all cracked
batteries even if you think all the acid has drained out. If you drop a battery, treat it as if
it is cracked. Put it into the containment area until you are sure it is not leaking.
7.5.2 Vehicle and Equipment Fueling
· If fueling must occur onsite, use designate areas, located away from drainage courses, to
prevent the runoff of storm water and the runoff of spills.
. Discourage "topping off' of fuel tanks.
. Always use secondary containment, such as a drain pan, when fueling to catch spills/
leaks.
7.53 Cleanup
. Clean up leaks and spills immediately.
· Use a rag for small spills on paved surfaces, a damp mop for general cleanup, and
absorbent material for larger spills. If the spilled material is hazardous, then the used
cleanup materials are also hazardous and must be sent to either a certified laundry (rags)
or disposed of as hazardous waste.
· Never hose down or bury dry material spills. Clean up as much of the material as possible
and dispose of properly.
7.54 Notification
Minn. Stat. 9115.061, which has been in effect since 1969, describes the duty of people to notify the
Minnesota Pollution Control Agency (MPCA) when spills and leaks occur:
115.061 - Duty to Notify and Avoid Water Pollution
(a) Except as provided in paragraph (b), it is the duty of every person to notify the agency
immediately of the discharge, accidental or otherwise, of any substance or material under its
control which, if not recovered, may cause pollution of waters of the state, and the responsible
person shall recover as rapidly and thoroughly as possible such substance or material and take
immediately such other action as may be reasonably possible to minimize or abate pollution of
waters of the state caused thereby.
(b) Notification is not required under paragraph (a) for a discharge of five gallons or less of
petroleum, as defined in section 115C.02, subdivision 10. This paragraph does not affect the other
requirements of paragraph (a). The law provides penalties of up to $10,000 per day for violations.
The Minnesota Department of Public Safety, Bureau of Criminal Apprehension, operates a 24-hour
service, establishing a one-call system for all state reporting requirements.
I
I
I

Reportable spills should be directed to the Minnesota Duty Officer by calling (651) 649-5451 or
(800) 422-0798.
The duty officer will record all pertinent information and then make the appropriate notifications to the
state agencies.
Spills that must be reported:
Report spills that may cause pollution; such as spills of toxic, flammable, corrosive and
dangerous industrial chemicals. Also report spills of environmentally damaging materials,
including fertilizer, coal, animal parts, batteries, etc.
Reportable quantities:
Minnesota has a reporting threshold of greater than five-gallons for petroleum spills. Spills of any
quantity of all other chemicals or materials should be reported. If in doubt, report.
7.6 Sanitary and Septic Waste
a. Portable toilets shall be located on site for sanitary waste collection.
1. Sanitary waste will be collected from the portable toilets in a timely manner to
avoid overfilling
2. Portable toilets are to be located ten feet away from storm drain inlets and at least
four feet behind a curb
8. Inspection and Maintenance
Storm Water Pollution Prevention inspections shall be conducted every seven (7) days or within 24 hours
after a rainfall event exceeding O.5-inches in 24 hours. The following shall be completed during each
inspection:
. Record name, date, and time of inspection
. Record rainfall amount if greater than O.5-inches
. Inspect the site for excess erosion and sedimentation
. Inspect the site for debris, trash, and spills
. Inspect temporary erosion and sedimentation control devices
. Inspect construction entrances for sediment tracking into streets
. Inspect areas which have undergone final stabilization at least once per month
. Record recommended repairs and modifications to erosion and sedimentation controls
. Record recommended changes to the SWPPP
· Record repairs and modifications implemented since previous inspections
Key areas identified for inspection, in addition to the above include:
. Inspect sediment control barriers for excessive sediment
. Inspect all flared end sections for excessive sediment
. Inspect adjacent streets for sediment, litter, and construction debris
The following guidelines shall be used to determine if pollution control devices require maintenance,
repair, or replacement:
. All silt fences shall be repaired, replaced, or supplemented when they become
nonfunctional or the sediment reaches 1/3 of the height of the fence. All repairs shall be
made within 24 hours of discovery, or as soon as field conditions allow access.
· All inlet protection devices shall be cleaned, repaired, or replaced when they become
nonfunctional or the sediment in the WIMCO's reach the top ofthe handles. All repairs
shall be made within 7 days of discovery, or as soon as field conditions allow access.
. All construction site vehicle entrance locations shall be repaired, replaced, or
supplemented when they become nonfunctional, filled with sediment, or allow off-site
I
I
sediment tracking onto paved surfaces. All repairs shall be made within 24 hours of
discovery, or as soon as field conditions allow access.
. All sediment escaping the construction site, observed on adjacent streets or other
properties, shall be removed in a manner and at a frequency sufficient to minimize off
site impacts.
. All excessive sediments and debris observed at flared end sections, in storm water ponds,
or drainage ditches and conveyance systems shall be removed within 7 days of discovery,
or as soon as field conditions allow access.
. All temporary and permanent sedimentation basins shall be drained and the sediment
removed when the depth of the sediment collected reaches Yz of the storage volume. All
repairs and maintenance shall be completed within 7 days of discovery, or as soon as
field conditions allow access.
. All infiltration areas shall be inspected to ensure that no sediment from construction
activity is reaching the infiltration area.
I
I
I
I
I
I
Where parts of the construction site have permanent cover, but work remains on other parts of the site,
inspections of the areas with permanent cover may be reduced to once per month. Where construction
sites have permanent cover on all exposed soil areas and no construction activity is occurring anywhere
on the site, the site must be inspected for a period of twelve (12) months (the inspections may be ceased
during frozen ground conditions). Following the twelfth month of permanent cover and no construction
activity, inspections may be terminated until construction activity is once again initiated or sooner if
notified in writing by the MPCA. Where work has been suspended due to frozen ground conditions, the
required inspections and maintenance schedule must begin within 24 hours after runoff occurs at the site
or prior to resuming construction, whichever comes first

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

How Soil Surveys Are Made
I
I
Soil surveys are made to provide information about the soils and miscellaneous areas
in a specific area. They include a description of the soils and miscellaneous areas and
their location on the landscape and tables that show soil properties and limitations
affecting various 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 observed and described many soil profiles. A soil profile is
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 or from the
surface down to bedrock. The unconsolidated material is devoid of roots and other
living organisms and has not been changed by other biological activity.
Currently, soils are mapped according to the boundaries of major land resource areas
(MLRAs). MLRAs are geographically associated land resource units that share
common characteristics related to physiography, geology, climate, water resources,
soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically
consist of parts of one or more MLRA.
The soils and miscellaneous areas in a 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 of
landform or with a segment of the landform. By observing the soils and miscellaneous
areas in the survey area and relating their position to specific segments of the
landform, a soil scientist develops a concept, or model, of how they were formed. Thus,
during mapping, this model enables the soil scientist to predict with a considerable
degree of accuracy the kind of soil or miscellaneous area at a specific location on the
landscape.
Commonly, individual soils on the landscape merge into one another as their
characteristics gradually change. To construct an accurate soil 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 soil-vegetation-Iandscape 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 studied. They
noted soil color, texture, size and shape of soil aggregates, kind and amount of rock
fragments, distribution of plant roots, 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.
The objective of soil mapping is not to delineate pure map unit components; the
objective is to separate the landscape into landforms or landform segments that have
similar use and management requirements. Each map unit is defined by a unique
combination of soil components and/or miscellaneous areas in predictable
proportions. Some components may be highly contrasting to the other components of
the map unit. The presence of minor components in a map unit in no way diminishes
the usefulness or accuracy of the data. The delineation of such landforms and
landform segments on the map provides sufficient information for the development of
resource plans. If intensive use of small areas is planned, onsite investigation is
needed to define and locate the soils and miscellaneous areas.
Soil scientists make many field observations in the process of producing a soil map.
The frequency of observation is dependent upon several factors, including scale of
mapping, intensity of mapping, design of map units, complexity of the landscape, and
experience of the soil scientist. Observations are made to test and refine the soil-
landscape model and predictions and to verify the classification of the soils at specific
locations. Once the soil-landscape model is refined, a significantly smaller number of
measurements of individual soil properties are made and recorded. These
measurements may include field measurements, such as those for color, depth to
bedrock, and texture, and laboratory measurements, such as those for content of
sand, silt, clay, salt, and other components. Properties of each soil typically vary from
one point to another across the landscape.
Observations for map unit components are aggregated to develop ranges of
characteristics for the components. The aggregated values are presented. Direct
measurements do not exist for every property presented for every map unit
component. Values for some properties are estimated from combinations of other
properties.
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 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. Some interpretations are
modified 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 high water table within certain depths in most years, but they cannot predict that a
high 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.

Map Unit Descriptions
I
The map units delineated on the detailed soil maps in a soil survey represent the soils
or miscellaneous areas in the survey area. The map unit descriptions, along with the
maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties ofthe 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.
I
I
I
I
10
I
I
I

I
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 mayor may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They generally
are in small areas and could not be mapped separately because of the scale used.
Some small areas of strongly contrasting soils or miscellaneous areas are identified
by a special symbol on the maps. If included in the database for a given area, the
contrasting minor components are identified in the map unit descriptions along with
some characteristics of each. A few areas of minor components may not have been
observed, and consequently they are not mentioned in the descriptions, especially
where the pattern was so complex that it was impractical to make enough observations
to identify all the soils and miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the usefulness
or accuracy of the data. The objective of mapping is not to delineate pure taxonomic
classes but rather to separate the landscape into landforms or landform segments that
have similar use and management requirements. The delineation of such segments
on the map provides sufficient information for the development of resource plans. If
intensive use of small areas is planned, however, onsite investigation is needed to
define and locate the soils and miscellaneous areas.
An identifying symbol precedes the map unit name in the map unit descriptions. Each
description includes general facts about the unit and gives important soil properties
and qualities.
Soils that have profiles that are almost alike make up a soil series. Except for
differences in texture of the surface layer, all the soils of a series have major horizons
that are similar in composition, thickness, and arrangement.
Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity,
degree of erosion, and other characteristics that affect their use. On the basis of such
differences, a soil series is divided into soil phases. Most of the areas shown on the
detailed soil maps are phases of soil series. The name of a soil phase commonly
indicates a feature that affects use or management. For example, Alpha silt loam, 0
to 2 percent slopes, is a phase of the Alpha series.
Some map units are made up of two or more major soils or miscellaneous areas.
These map units are complexes, associations, or undifferentiated groups.
A complex consists of two or more soils or miscellaneous areas in such an intricate
pattern or in such small areas that they cannot be shown separately on the maps. The
pattern and proportion of the soils or miscellaneous areas are somewhat similar in all
areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example.
An association is made up of two or more geographically associated soils or
miscellaneous areas that are shown as one unit on the maps. Because of present or
anticipated uses of the map units in the survey area, it was not considered practical
or necessary to map the soils or miscellaneous areas separately. The pattern and
relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-
Beta association, 0 to 2 percent slopes, is an example.
An undifferentiated group is made up of two or more soils or miscellaneous areas that
could be mapped individually but are mapped as one unit because similar
interpretations can be made for use and management. The pattern and proportion of
the soils or miscellaneous areas in a mapped area are not uniform. An area can be
