Langan Project No.: 281015401
INTRODUCTION
Langan NC, Inc. (Langan) has prepared this soil testing memo for the site located in the Village of
Marvin, Union County, North Carolina. The purpose of this memo is to present the required and
completed soil testing, along with how the two (2) proposed infiltrations basins are designed to
promote infiltration.
SITE DESCRIPTION
The site is generally wooded with areas of existing low herbaceous ground cover and a single existing
house with driveway located in the northeastern corner of the property. The site is split by a ridgeline
following the existing driveway generally sloping down towards the northeastern corner and away
from the driveway to Marvin Branch in the east and Six Mile Creek in the north. Numerous existing
natural swales cross the property leading to channelized runoff entering both receiving waterways.
Slopes are generally shallow between 3%-10% except for the sides of the previously mentioned
existing natural swales.
The project site is located within the Six Mile Watershed, which adheres to the Goose Creek
Watershed rules outlined in 15A NCAC 2B .0600-.0609.
SOIL TESTING RESULTS
Per, 15A NCAC 2B .0602, any new development activity that disturbs one (1) acre or more of land
within the Goose Creek Watershed, and will result in addition of impervious surface, shall control and
treat the difference in the stormwater runoff from the pre- and post-development conditions for the
one-year, 24-hour storm, with structural stormwater controls, and shall implement stormwater
management measures that promote infiltration. Therefore, two (2) infiltrations basins are proposed
for this site—one for each on-site drainage area.
Per Section A-2 of the NCDEQ Stormwater Design Manual, in-situ soil testing is required to determine
the infiltration rate and seasonal high-water table (SHWT)for infiltration stormwater control measures
(SCMs). Additionally, the number of test pits is dictated by the area of infiltration system. Both

infiltrations basins have a bottom of basin less than 2,000-SF, so only one (1) test pit per basin was
required.
Based on knowledge of the surrounding in-situ soil, it was decided prior to testing to replace the in-
situ soil below the basins with an engineered infiltration media. Therefore, infiltration testing was not
needed nor completed. However, prior to installation, the contractor shall provide testing from the
manufacturer that shows the engineered media has an infiltration rate of 5 inches/hour.
On 15 April 2024, two (2) test pits were observed by Langan to determine the SHWT (see Figure 1,
Test Pit Plan). Below is a summary of the test pits.
Test Pit 1:
The test pit was excavated to a depth of 8.10 feet bgs (below ground surface). Rock fragments were
encountered at 6.5 feet bgs (below ground surface). There were no indicators of seasonal high water
table identified from the test pit. The test pit was left open for 24 hours and groundwater seepage
was observed at an elevation of 6.17 feet bgs (el 570.00).
Test Pit 2:
The test pit was excavated to a depth of 20.17 feet bgs (below ground surface). There were no
indicators of seasonal high water table identified from the test pit. The test pit was left open for 24
hours and groundwater seepage was observed at an elevation of 16.50 feet bgs (el 573.00).
*Indicators of SHWT refer to the presence of soil mottling of chroma 2 or less, typically the result of
reduced iron. Chroma 2 mottles also indicate horizons within the soil profile that are potentially
restrictive with respect to water movement through the soil profile, which has resulted in the
subsequent reduction of iron.
INFILTRATION BASIN DESIGN
As aforementioned, the in-situ soils below both infiltration basins are to be replaced with an
engineered infiltration media that has an infiltration rate of 5 inches/hour. This proposed infiltration
rate is based on a minimum drawdown time of 48 hours and a maximum drawdown time of 72 hours.
For Infiltration Basin 1, this equals 2-FT of engineered media from el. 572.00 to 570.00, and for
Infiltration Basin 2, this equals 3-FT of engineered media from el. 576.00 to 573.00 to promote
infiltration into the groundwater table.

Langan Project No.: 281015401
INTRODUCTION
Langan NC, Inc. (Langan) has prepared this soil testing memo for the site located in the Village
of Marvin, Union County, North Carolina. The purpose of this memo is to present the required
and completed soil testing, along with how the two (2) proposed infiltrations basins are designed
to promote infiltration.
SITE DESCRIPTION
The site is generally wooded with areas of existing low herbaceous ground cover and a single
existing house with driveway located in the northeastern corner of the property. The site is split
by a ridgeline following the existing driveway generally sloping down towards the northeastern
corner and away from the driveway to Marvin Branch in the east and Six Mile Creek in the north.
Numerous existing natural swales cross the property leading to channelized runoff entering both
receiving waterways. Slopes are generally shallow between 3%-10% except for the sides of the
previously mentioned existing natural swales.
The project site is located within the Six Mile Watershed, which adheres to the Goose Creek
Watershed rules outlined in 15A NCAC 2B .0600-.0609.
SOIL TESTING RESULTS
Per, 15A NCAC 2B .0602, any new development activity that disturbs one (1) acre or more of
land within the Goose Creek Watershed, and will result in addition of impervious surface, shall
control and treat the difference in the stormwater runoff from the pre- and post-development
conditions for the one-year, 24-hour storm, with structural stormwater controls, and shall
implement stormwater management measures that promote infiltration. Therefore, two (2)
infiltrations basins are proposed for this site — one for each on-site drainage area.
Per Section A-2 of the NCDEQ Stormwater Design Manual, in-situ soil testing is required to
determine the infiltration rate and seasonal high-water table (SHWT) for infiltration stormwater

control measures (SCMs). Additionally, the number of test pits is dictated by the area of
infiltration system. Both infiltrations basins have a bottom of basin less than 2,000-SF, so only
one (1) test pit per basin was required.
Based on knowledge of the surrounding in-situ soil, it was decided prior to testing to replace the
in-situ soil below the basins with an engineered infiltration media. Therefore, infiltration testing
was not needed nor completed. However, prior to installation, the contractor shall provide testing
from the manufacturer that shows the engineered media has an infiltration rate of 5 inches/hour.
On 15 April 2024, two (2) test pits were observed by Langan to determine the SHWT (see Figure
1, Test Pit Plan). For Test Pit 1, rock was encountered at approximately 6.5-FT below grade (el.
569.60), and no initial groundwater was observed. For Test Pit 2, no rock was encountered, and
no initial groundwater was observed. Both test pits were left open for 24 hours, and groundwater
levels were observed at approximately 6.17-FT below grade (el. 570.00) for Test Pit 1, and at
approximately 16.5-FT below grade (el. 573.00) for Test Pit 2. These final groundwater elevations
were used to design the infiltration basins as outlined below.
INFILTRATION BASIN DESIGN
As aforementioned, the in-situ soils below both infiltration basins are to be replaced with an
engineered infiltration media that has an infiltration rate of 5 inches/hour. This proposed
infiltration rate is based on a minimum drawdown time of 48 hours and a maximum drawdown
time of 72 hours. For Infiltration Basin 1, this equals 2-FT of engineered media from el. 572.00 to
570.00, and for Infiltration Basin 2, this equals 3-FT of engineered media from el. 576.00 to 573.00
to promote infiltration into the groundwater table.

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.nres.usda.gov/wps/portal/nres/detail/soils/contactus/?
cid=nres142p2_053951).
Great differences in soil properties can occur within short distances. Some soils are
seasonally wet or subject to flooding. Some are too unstable to be used as a
foundation for buildings or roads. Clayey or wet soils are poorly suited to use as
septic tank absorption fields. A high water table makes a soil poorly suited to
basements or underground installations.
The National Cooperative Soil Survey is a joint effort of the United States
Department of Agriculture and other Federal agencies, State agencies including the
Agricultural Experiment Stations, and local agencies. The Natural Resources
Conservation Service (NRCS) has leadership for the Federal part of the National
Cooperative Soil Survey.
Information about soils is updated periodically. Updated information is available
through the NRCS Web Soil Survey, the site for official soil survey information.

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

Custom Soil Resource Report
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
6

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
12

Custom Soil Resource Report
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
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
13

Custom Soil Resource Report
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.
