1.0 Introduction

Crosswind Development, Inc. is proposing a 42-unit townhome subdivision comprising
approximately 7.15 acres. The site is located within the Town of Franklinton on East Green Street
(NC Highway 56) on Franklin County Parcel ID No. 1865-66-0607. This report details the
stormwater management design for the project.

2.0 Site Description

The existing 7.15-acre parcel is vacant with wooded and existing asphalt areas. The site is
located within the Town of Franklinton and is not within the Tar-Pamlico watershed. The total
proposed impervious area is 25.9% of the site.

Based on a review Federal Emergency Management Agency (FEMA) map number 3720186400J,
dated April 16, 2013, no portion of the parcel lies within a FEMA designated 100-year floodplain.
The FEMA map is included as Appendix A.

Wetland and stream delineations were performed by Carolina Ecosystems, Inc (CEI). Buffered
streams exist on the southeast and southwest parcel boundaries and were delineated and
mapped by CEI. The approved Jurisdictional Determinations (JDs) from the United States Army
Corps of Engineers (USACE) is included as Appendix B. Buffer authorization approvals for
disturbance within the outer 20’ (Zone 2) of the stream buffers are pending with NCDWR at the
time of this submittal.

Excerpts from the United States Geological Survey (USGS) topographic 7.5’ quadrangle map and
USDA SCS Soil Survey Map are included within the JD application in Appendix C. The property
generally drains to the south. Topography on the site ranges from elevation 401’ to elevation
355’. Soils on the site are Hydrologic Soil Group (HSG) B and D as described in the National
Resources Conservation Service (NRCS) soils report in Appendix D.

3.0 Proposed Development

The proposed development will consist of 42 townhomes and a private access drive. The total
proposed impervious surface area for the project, including townhomes, sidewalk, access drive,
and mail kiosk is approximately 1.85 acres.

4.0 Stormwater Management

4.1 Design Data and Methodologies

The design of the proposed stormwater management facilities was performed in accordance with
the North Carolina Department of Environmental Quality (NCDEQ) Stormwater Best Management
Practice (BMP) Manual. The requirements states that the new development shall not result in a
net increase in peak flow leaving the site from pre-development conditions for the one-year, 24-
hour storm event. The Town of Franklinton is not located within the Tar-Pamlico, Neuse, or Falls
Lake watersheds. Nutrient management is therefore not required for the site.

HydroCAD Version 8.50, a computer modeling software package, was used for the analysis of
stormwater routing and hydrology of the existing and proposed watersheds. The hydrology
calculations were performed using the Natural Resources Conservation Service (NRCS) Soil
Conservation Service (SCS) Technical Release 55 (TR-55) methodology. Franklin County lies
within the Type II rainfall distribution. The rainfall amounts for the site were obtained from the
National Oceanic and Atmospheric Administration (NOAA) and are included in Appendix E.

4.2 Pre-development Analysis

The pre-development watershed was approximated based on an aerial assessment of the site,
Franklin County topographic data, and surveyed topographic data. The peak flow rate for the 1-
year, 24-hour storm event is based on the topography, land use cover (such as open space,
grass, woods, etc.), and soil type.

The 6.62-acre existing watershed was modeled in HydroCAD as one subcatchment as described
below. East Green Street was considered the high point of the drainage area. Refer to Appendix
F for the pre-development watershed map.

 Subcatchment DA-1: Subcatchment DA-1 is 6.62 acres and drains south across the
parcel. Due to the existing impervious area on site, a time of concentration of 3.3 minutes
was calculated for the subcatchment. Therefore, a conservative time of concentration of
6 minutes was used for the subcatchment

The pre-development hydrologic model is included in Appendix G. Table 4-1 summarizes the pre-
development hydrologic model results.

Table 4-1
Pre-development Hydrologic Model Results
Storm Event (24-hour) Pre-development Peak Flow (CFS)
1-year 7.10

4.3 Post-development Analysis

An analysis of the post-development runoff was performed using the same methods, parameters,
and assumptions as described in the pre-development analysis above. Based upon the hydrologic
calculations, the project does not create an increase in the peak runoff rate for the 1-year, 24-
hour storm event. Refer to Appendix H of this report for the post-development watershed map.
The 6.62-acre watershed was modeled in HydroCAD as two subcatchments as described below.

 Subcatchment DA-2: Subcatchment DA-4 is 4.0 acres and includes the area draining to
the proposed stormwater wetland. A conservative time of concentration of six minutes
was used for the subcatchment.

 Subcatchment DA-3: Subcatchment DA-3 is 2.62 acres. This subcatchment is bypass
areas not treated by the proposed wetland. A conservative time of concentration of six
minutes was used for the subcatchment.

The post-development hydrologic model is included in Appendix I. Table 4-2 summarizes the pre-
development hydrologic model results.

4.4 Stormwater Management Summary

This project will not increase peak flow rate for the 1-year, 24-hour storm event. Stormwater
facilities that do not increase the peak flow rate help prevent adverse downstream impacts from
flooding and erosion. Table 4-3 compares the pre-development and post-development peak flow
rates for the design storm event.

The stormwater control measure (SCM) was sized to provide peak rate of runoff attenuation and
are larger than the sizes necessary to treat the first one-inch of rainfall. The supplemental form
for the proposed stormwater wetland is included in Appendix J.

The proposed stormwater wetland is anticipated to draw down the design volume within 2 to 5
days. Draw down calculations are provided in Appendix K.

The seasonal high water table (SHWT) in the location of the SCM was determined by Carolina
Ecosystems, Inc. to be as shown in Table 4-4 below and listed in Appendix L.

Base map information shown on this FIRM was provided in digital format by the North Carolina Floodplain
Mapping Program (NCFMP). The source of this information can be determined from the metadata available in the
digital FLOOD database and in the Technical Support Data Notebook (TSDN).
ACCREDITED LEVEE NOTES TO USERS: If an accredited levee note appears on this panel check with your local
community to obtain more information, such as the estimated level of protection provided (which may exceed the
1-percent-annual-chance level) and Emergency Action Plan, on the levee system(s) shown as providing protection.
To mitigate flood risk in residual risk areas, property owners and residents are encouraged to consider flood
insurance and floodproofing or other protective measures. For more information on flood insurance, interested
parties should visit the FEMA Website at http://www.fema.gov/business/nfip/index.shtm.
PROVISIONALLY ACCREDITED LEVEE NOTES TO USERS: If a Provisionally Accredited Levee (PAL) note
appears on this panel, check with your local community to obtain more information, such as the estimated level of
protection provided (which may exceed the 1-percent-annual-chance level) and Emergency Action Plan, on the
levee system(s) shown as providing protection. To maintain accreditation, the levee owner or community is
required to submit the data and documentation necessary to comply with Section 65.10 of the NFIP regulations.
If the community or owner does not provide the necessary data and documentation or if the data and documentation
provided indicates the levee system does not comply with Section 65.10 requirements, FEMA will revise the flood
hazard and risk information for this area to reflect de-accreditation of the levee system. To mitigate flood risk in
residual risk areas, property owners and residents are encouraged to consider flood insurance and floodproofing

It is approximately 600 feet southwest of the East Green Street, Oak Ridge Road intersection.
Indicate Which of the Following Apply:
A. Preliminary Determination
X There are waters on the above described property, that may be subject to Section 404 of the Clean Water Act
(CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). The waters have been
delineated, and the delineation has been verified by the Corps to be sufficiently accurate and reliable. Therefore this
preliminary jurisdiction determination may be used in the permit evaluation process, including determining compensatory
mitigation. For purposes of computation of impacts, compensatory mitigation requirements, and other resource protection
measures, a permit decision made on the basis of a preliminary JD will treat all waters and wetlands that would be affected
in any way by the permitted activity on the site as if they are jurisdictional waters of the U.S. This preliminary
determination is not an appealable action under the Regulatory Program Administrative Appeal Process (Reference 33
CFR Part 331). However, you may request an approved JD, which is an appealable action, by contacting the Corps district
for further instruction.
There are wetlands on the above described property, that may be subject to Section 404 of the Clean Water Act
(CWA)(33 USC § 1344) and/or Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403). However, since the
waters, including wetlands, have not been properly delineated, this preliminary jurisdiction determination may not be
used in the permit evaluation process. Without a verified wetland delineation, this preliminary determination is merely an
effective presumption of CWA/RHA jurisdiction over all of the waters, including wetlands, at the project area, which is
not sufficiently accurate and reliable to support an enforceable permit decision. We recommend that you have the
waters of the U.S. on your property delineated. As the Corps may not be able to accomplish this wetland delineation in a
timely manner, you may wish to obtain a consultant to conduct a delineation that can be verified by the Corps.
B. Approved Determination
There are Navigable Waters of the United States within the above described property subject to the permit requirements of
Section 10 of the Rivers and Harbors Act (RHA) (33 USC § 403) and Section 404 of the Clean Water Act (CWA)(33 USC
§ 1344). Unless there is a change in law or our published regulations, this determination may be relied upon for a period
not to exceed five years from the date of this notification.
There are waters of the U.S., including wetlands, on the above described project area subject to the permit requirements
of Section 404 of the Clean Water Act (CWA) (33 USC § 1344). Unless there is a change in the law or our published
regulations, this determination may be relied upon for a period not to exceed five years from the date of this notification.
We recommend you have the waters of the U.S. on your property delineated. As the Corps may not be able to
accomplish this wetland delineation in a timely manner, you may wish to obtain a consultant to conduct a delineation that
can be verified by the Corps.
SAW-2017-01946
The waters of the U.S., including wetlands, on your project area have been delineated and the delineation has been
verified by the Corps. If you wish to have the delineation surveyed, the Corps can review and verify the survey upon
completion. Once verified, this survey will provide an accurate depiction of all areas subject to CWA and/or RHA
jurisdiction on your property which, provided there is no change in the law or our published regulations, may be relied
upon for a period not to exceed five years.
The waters of the U.S., including wetlands, have been delineated and surveyed and are accurately depicted on the plat
signed by the Corps Regulatory Official identified below on ______________. Unless there is a change in the law or our
published regulations, this determination may be relied upon for a period not to exceed five years from the date of this

RE: Request for Preliminary Jurisdictional Determination
Green Street Property
Franklinton, Franklin County, North Carolina

Dear Mr. Williams,

Carolina Ecosystems, Inc. (CEI) has completed a delineation of streams and wetlands for the
above referenced project. The attached information, including required forms, tables, and figures,
is submitted for your review and determination of jurisdiction under the Clean Water Act
(CWA).

Project Description & Methodology

As shown in Figure 1, the site is located in Franklinton, Franklin County, NC within the Tar-
Pamlico River Basin (USGS HUC 03020101). The site is comprised of 1 parcel totaling 6.9
acres.

This investigation was performed in compliance with methodology set forth in the U.S. Army
Corps of Engineers (USACE) Wetland Delineation Manual (USACE 1987) and subsequent
guidance including the Eastern Mountains and Piedmont Regional Supplement. Streams were
assessed for jurisdiction under the CWA using field indications of ordinary high water mark, and
the North Carolina Division of Water Quality (NCDWQ) Stream Identification Form, Version
4.11. Streams were flagged at representative points to depict jurisdictional starting points.

Delineation Results

Figure 2 is presented using the Franklinton (2013) US Geological Survey 1:24,000 Quadrangle
Maps. Figure 3 presents the results of the delineation, including two streams and no wetland.

Table 1 presents detailed information on each jurisdictional feature within the study area,
including latitude/longitude, Cowardin classification, estimated amount of aquatic resource in
review area, and class of aquatic resource. Based on field data, there is approximately 755 linear
feet of perennial stream present within the study area.

We respectfully request your review of this information, so that a preliminary jurisdictional
determination under the CWA may be obtained. If you have any questions, need additional

I. REQUESTS FOR CORPS APPROVAL OF SURVEY PLAT

Prior to final production of a Plat, the Wilmington District recommends that the Land
Surveyor electronically submit a draft of a Survey Plat to the Corps project manager for
review.

Due to storage limitations of our administrative records, the Corps requires that all hard-
copy submittals include at least one original Plat (to scale) that is no larger than 11”x17”
(the use of match lines for larger tracts acceptable). Additional copies of a plat, including
those larger than 11”x17”, may also be submitted for Corps signature as needed. The
Corps also accepts electronic submittals of plats, such as those transmitted as a Portable
Document Format (PDF) file. Upon verification, the Corps can electronically sign these
plats and return them via e-mail to the requestor.

(1) PLATS SUBMITTED FOR APPROVAL

Must be sealed and signed by a licensed professional land surveyor

Must be to scale (all maps must include both a graphic scale and a verbal scale)

Must be legible

Must include a North Arrow, Scale(s), Title, Property Information

Must include a legible WoUS Delineation Table of distances and bearings/metes
and bounds/GPS coordinates of all surveyed delineation points

Must clearly depict surveyed property or project boundaries

Must clearly identify the known surveyed point(s) used as reference (e.g. property
corner, USGS monument)

When wetlands are depicted:

• Must include acreage (or square footage) of wetland polygons
• Must identify each wetland polygon using an alphanumeric system

1. The Corps of Engineers believes that there may be jurisdictional waters of the
United States on the subject site, and the permit applicant or other affected party
who requested this preliminary JD is hereby advised of his or her option to
request and obtain an approved jurisdictional determination (JD) for that site.
Nevertheless, the permit applicant or other person who requested this
preliminary JD has declined to exercise the option to obtain an approved JD in
this instance and at this time.

2. In any circumstance where a permit applicant obtains an individual permit, or
a Nationwide General Permit (NWP) or other general permit verification requiring
“pre-construction notification” (PCN), or requests verification for a non-reporting
NWP or other general permit, and the permit applicant has not requested an
approved JD for the activity, the permit applicant is hereby made aware of the
following: (1) the permit applicant has elected to seek a permit authorization
based on a preliminary JD, which does not make an official determination of
jurisdictional waters; (2) that the applicant has the option to request an approved
JD before accepting the terms and conditions of the permit authorization, and
that basing a permit authorization on an approved JD could possibly result in less
compensatory mitigation being required or different special conditions; (3) that
the applicant has the right to request an individual permit rather than accepting
the terms and conditions of the NWP or other general permit authorization; (4)
that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking
any activity in reliance upon the subject permit authorization without requesting
an approved JD constitutes the applicant’s acceptance of the use of the
preliminary JD, but that either form of JD will be processed as soon as is
practicable; (6) accepting a permit authorization (e.g., signing a proffered
individual permit) or undertaking any activity in reliance on any form of Corps
permit authorization based on a preliminary JD constitutes agreement that all
wetlands and other water bodies on the site affected in any way by that activity
are jurisdictional waters of the United States, and precludes any challenge to
such jurisdiction in any administrative or judicial compliance or enforcement
action, or in any administrative appeal or in any Federal court; and (7) whether
the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual
permit denial can be administratively appealed pursuant to 33 C.F.R. Part 331,
and that in any administrative appeal, jurisdictional issues can be raised (see 33
C.F.R. 331.5(a)(2)). If, during that administrative appeal, it becomes necessary
to make an official determination whether CWA jurisdiction exists over a site, or
to provide an official delineation of jurisdictional waters on the site, the Corps will
provide an approved JD to accomplish that result, as soon as is practicable.
4
This preliminary JD finds that there “may be” waters of the United States on the
subject project site, and identifies all aquatic features on the site that could be
affected by the proposed activity, based on the following information:

IMPORTANT NOTE: The information recorded on this form has not
necessarily been verified by the Corps and should not be relied upon for
later jurisdictional determinations.

Preface
Soil surveys contain information that affects land use planning in survey areas.
They highlight soil limitations that affect various land uses and provide information
about the properties of the soils in the survey areas. Soil surveys are designed for
many different users, including farmers, ranchers, foresters, agronomists, urban
planners, community officials, engineers, developers, builders, and home buyers.
Also, conservationists, teachers, students, and specialists in recreation, waste
disposal, and pollution control can use the surveys to help them understand,
protect, or enhance the environment.
Various land use regulations of Federal, State, and local governments may impose
special restrictions on land use or land treatment. Soil surveys identify soil
properties that are used in making various land use or land treatment decisions.
The information is intended to help the land users identify and reduce the effects of
soil limitations on various land uses. The landowner or user is responsible for
identifying and complying with existing laws and regulations.
Although soil survey information can be used for general farm, local, and wider area
planning, onsite investigation is needed to supplement this information in some
cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/
portal/nrcs/main/soils/health/) and certain conservation and engineering
applications. For more detailed information, contact your local USDA Service Center
(https://offices.sc.egov.usda.gov/locator/app?agency=nrcs) or your NRCS State Soil
Scientist (http://www.nrcs.usda.gov/wps/portal/nrcs/detail/soils/contactus/?
cid=nrcs142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

How Soil Surveys Are Made
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-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 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
5
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
The map units delineated on the detailed soil maps in a soil survey represent the
soils or miscellaneous areas in the survey area. The map unit descriptions, along
with the maps, can be used to determine the composition and properties of a unit.
A map unit delineation on a soil map represents an area dominated by one or more
major kinds of soil or miscellaneous areas. A map unit is identified and named
according to the taxonomic classification of the dominant soils. Within a taxonomic
class there are precisely defined limits for the properties of the soils. On the
landscape, however, the soils are natural phenomena, and they have the
characteristic variability of all natural phenomena. Thus, the range of some
observed properties may extend beyond the limits defined for a taxonomic class.
Areas of soils of a single taxonomic class rarely, if ever, can be mapped without
including areas of other taxonomic classes. Consequently, every map unit is made
up of the soils or miscellaneous areas for which it is named and some minor
components that belong to taxonomic classes other than those of the major soils.
Most minor soils have properties similar to those of the dominant soil or soils in the
map unit, and thus they do not affect use and management. These are called
noncontrasting, or similar, components. They may or may not be mentioned in a
particular map unit description. Other minor components, however, have properties
and behavioral characteristics divergent enough to affect use or to require different
management. These are called contrasting, or dissimilar, components. They
generally are in small areas and could not be mapped separately because of the
scale used. Some small areas of strongly contrasting soils or miscellaneous areas
are identified by a special symbol on the maps. If included in the database for a
given area, the contrasting minor components are identified in the map unit
descriptions along with some characteristics of each. A few areas of minor
components may not have been observed, and consequently they are not
mentioned in the descriptions, especially where the pattern was so complex that it
was impractical to make enough observations to identify all the soils and
miscellaneous areas on the landscape.
The presence of minor components in a map unit in no way diminishes the
usefulness or accuracy of the data. The objective of mapping is not to delineate
pure taxonomic classes but rather to separate the landscape into landforms or
Custom Soil Resource Report

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 made up of only one of the major soils or miscellaneous areas, or it can be made
up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example.
Some surveys include miscellaneous areas. Such areas have little or no soil
material and support little or no vegetation. Rock outcrop is an example.

Soil Information for All Uses
Soil Properties and Qualities
The Soil Properties and Qualities section includes various soil properties and
qualities displayed as thematic maps with a summary table for the soil map units in
the selected area of interest. A single value or rating for each map unit is generated
by aggregating the interpretive ratings of individual map unit components. This
aggregation process is defined for each property or quality.
Soil Qualities and Features
Soil qualities are behavior and performance attributes that are not directly
measured, but are inferred from observations of dynamic conditions and from soil
properties. Example soil qualities include natural drainage, and frost action. Soil
features are attributes that are not directly part of the soil. Example soil features
include slope and depth to restrictive layer. These features can greatly impact the
use and management of the soil.
Hydrologic Soil Group
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 long-duration storms.
The soils in the United States are assigned to four groups (A, B, C, and D) and
three dual classes (A/D, B/D, and C/D). The groups are defined as follows:
Group A. Soils having a high infiltration rate (low runoff potential) when thoroughly
wet. These consist 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.
18
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.
If a soil is assigned to a dual hydrologic group (A/D, B/D, or C/D), the first letter is
for drained areas and the second is for undrained areas. Only the soils that in their
natural condition are in group D are assigned to dual classes.

distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more

Soil Reports
The Soil Reports section includes various formatted tabular and narrative reports
(tables) containing data for each selected soil map unit and each component of
each unit. No aggregation of data has occurred as is done in reports in the Soil
Properties and Qualities and Suitabilities and Limitations sections.
The reports contain soil interpretive information as well as basic soil properties and
qualities. A description of each report (table) is included.
AOI Inventory
This folder contains a collection of tabular reports that present a variety of soil
information. Included are various map unit description reports, special soil
interpretation reports, and data summary reports.
Map Unit Description (Brief, Generated)
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 in this
report, along with the maps, provide information on the composition of map units
and properties of their components.
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.
The Map Unit Description (Brief, Generated) report displays a generated description
of the major soils that occur in a map unit. Descriptions of non-soil (miscellaneous
areas) and minor map unit components are not included. This description is
generated from the underlying soil attribute data.
Additional information about the map units described in this report is available in
other Soil Data Mart reports, which give properties of the soils and the limitations,
capabilities, and potentials for many uses. Also, the narratives that accompany the
Soil Data Mart reports define some of the properties included in the map unit
descriptions.

1 Precipitation frequency (PF) estimates in this table are based on frequency analysis of partial duration series (PDS).
Numbers in parenthesis are PF estimates at lower and upper bounds of the 90% confidence interval. The probability that precipitation frequency estimates (for
a given duration and average recurrence interval) will be greater than the upper bound (or less than the lower bound) is 5%. Estimates at upper bounds are not
checked against probable maximum precipitation (PMP) estimates and may be higher than currently valid PMP values.
Please refer to NOAA Atlas 14 document for more information.
