All proposed infiltration areas and existing, active utility lines located within the proposed
basinArench must be marked and flagged. If these areas are not flagged, the Soils Scientist
reserves the right to decline to do the investigation. If the proposed infiltration system will be
located in an area of existing pavement and there is no open area nearby, equipment capable of
breaking through the impervious layer must be provided. The soils investigation does not take
the place of a soils report prepared by an appropriate professional. The Soils Scientist will only
verify the soil conditions that are reported in the Soils Report, and make a determination as to
the suitability of the site to meet the infiltration design requirements under NCAC 2H. 1000, and
assumes no liability should the system fail.

Reference: Soil Assessment for Proposed Storm Water Proposal for Beach Road GoGas,
Brunswick County, NC
Dear Phil,
Land Management Group, Inc. evaluated the parcel for the purpose of providing
site data to the engineer for his submittal of the proposed storm water retention plan for
the proposed business. The purpose of the evaluation was to describe the soil profiles,
quantify the depth to the seasonal high water table, estimate permeability and to inform
the project engineer of any potential limitations of this project within the proposed
stormwater retention areas
The soils at this site are mapped as Foreston and Yaupon in the Soil Survey of
Brunswick County (USDA, 1986). Soil borings 1 and 2 are like the Yaupon soil type.
The soil boring locations are shown in Appendix A and the soil profile descriptions are
shown in Appendix B. Soil descriptions for Foreston and Yaupon are shown in
Appendix C.
The site contains an existing stormwater structure along the rear of the property as
shown in Appendix A. Borings were made at the existing grade just outside of the
stormwater structure. This feature appears to have been installed in the early 1990's.
Prior to this time the site had been used as the dredge spoil location for the cooling water
canal from the Progress Energy Plant. The fines from the pumping settled in the
topographic lows within the containment dike and coincide with this site location. This
work was performed in the late 1960's.
The seasonal high water table found in most soils is normally evident by
observation of redoximorphic features suggesting past conditions of saturation and
reduction. In the same way, there can be modern drainage features such as canals or
ditches that have altered the hydrologic profile. Often, observed redoximorphic features
are relicts of previous hydrologic conditions but not current ones. The mottles observed
in the dark colored material of the fill layers are from the spoil that was pumped out of
the canal from the adjacent tract and are not indicative of the seasonal high water table.
The under -lying soil horizons are identical to those found in the soil mapped as Foreston.
The degree of expression of mottles as shown in Appendix B is evidence that SHWT
occurs at 62" for soil borings 1 and 2.
Soil permeability is estimated based on soil physical properties. The following
are estimates of the soils at each location. Boring one has an estimated permeability of
0.1 - 0.15 inches per hour in the silty clay loam horizon. The lower BT horizon had an
estimated permeability of 4.0 - 6.0 inches per hour. Boring two has similar permeability
rates. The heavy layers in this area could be excavated and replaced with clean, sand fill
for a proposed stormwater system.
In summary, this site has one areas that is proposed for stormwater system
placement. These areas have soils that have seasonal high water tables that are 64" from
the soil surface in the two locations.
If the proposed Permanent Pool Elevation is more than 6" below the seasonal high
water table elevation, then additional testing and analysis may be required to quantify any
affect on adjacent wetlands, surface waters, and/or buffers where applicable. Please refer
to the NC DENR DWQ February 19, 2009 Memo Article 2 subsections a-d for further
guidance. Please do not hesitate to contact me if you have any questions with this report
or if you wish for LMG to perform any additional site specific studies in accordance with
the NC DENR DWQ guidance memo. If you have any questions about this report or
need any additional information I may be reached at 910-452-0001, 910-620-1 137 or at

Ocilla, Paxville, Rains, Rutlee, and Wagram soils. The Autryville, Bonneau, Chisolm,
Dothan, Fuquay, Norfolk, and Wagram soils are in slightly higher positions on the
landscape and are better drained. In addition, these soils, except for Dothan and Norfolk,
are arenic. They all have fine -loamy Bt horizons. The Goldsboro soils are in a similar
position on the landscape, but they are fine -loamy. Lynchburg, Ocilla, Paxville and Rains
soils are in slightly lower positions on the landscape and are more poorly drained and
have fine -loamy Bt horizons. Leon, Lynn Haven and Rutlege soils are in the lowest
position on the landscape, are more poorly drained, and are sandy throughout.
DRAINAGE AND PERMEABILITY: Moderately well drained. Surface runoff is slow.
Permeability is moderately rapid.
USE AND VEGETATION: Most areas of these soils have been cleared and are cropped
to corn, cotton, tobacco, soybeans, and hay crops. Vegetation of forested areas include
various species of pine with mixed hardwoods.

YAUPON SERIES
The Yaupon series consists of somewhat poorly drained to moderately well drained,
slowly permeable soils in the Lower Coastal Plain. The soils formed in fine textured soil
material deposited by dredging operations. Slopes range from 0 to 15 percent.
TAXONOMIC CLASS: Fine, mixed, semiactive, nonacid, thermic Aquic Udorthents
TYPICAL PEDON: Yaupon silty clay loam.
(Colors are for moist unless otherwise stated).
A1--0 to 7 inches; dark gray (IOYR 4/1) silty clay loam, common medium distinct
yellowish red (5YR 4/6) mottles; moderate medium platy structure; firm, sticky, plastic,
few fine roots; very strongly acid; gradual smooth boundary. (0 to 10 inches thick)
Clg--7 to 20 inches; dark gray (5YR 4/1) silty clay; massive; very firm, very sticky, very
plastic; mildly alkaline; gradual smooth boundary. (5 to 20 inches thick)
C2g--20 to 30 inches; dark greenish gray (5GY 4/1) silty clay; common medium distinct
dark gray (5Y 4/1) mottles; massive; firm, very sticky, very plastic; few small dark
reddish brown (5YR 312) concretions; moderately alkaline; gradual smooth boundary. (5
to 10 inches thick)
C3g--30 to 76 inches; dark greenish gray (5GY 411) silty clay; massive; firm, very sticky,
very plastic; few small dark reddish brown (5YR 3/2) concretions; moderately alkaline;
clear smooth boundary. (10 to 50 inches thick)
Ab--76 to 85 inches; black (10YR 2/1) fine sandy loam; weak medium granular structure;
very friable; very strongly acid. (0 to 15 inches thick)
TYPE LOCATION: Brunswick County, North Carolina; .l mile northeast of the Bridge
of NC 133 Highway and the lntercoastal Waterway; 0.1 mile south of the intersection of
NC 133 Highway and service road.
RANGE IN CHARACTERISTICS: Thickness of the dredge spoil soil material ranges
from 20 to more than 80 inches. Shrinkage cracks open at the surface range from 15 to 35
inches apart and are from 2 to 4 inches wide ranging up to 6 or 8 inches in some places,
about 30 inches deep, they are commonly filled with fine sand. Reaction range from very
strongly acid to medium acid in the surface layer except where limed and from strongly
acid to moderately alkaline in the C horizon. Shells and shell fragments range from 0 to
20 percent in individual horizons. The grey color is not indicative of the present drainage
but of the condition of the original sediments.
The A 1 horizon has hue of l OYR to 5Y, value of 3 to 6, and chroma of 0 to 2. The A
horizon is fine sandy loam, loam, silt loam, and silty clay loam.
The C horizon has hue of I OYR to 5G or 5B, value of 4 to 6 and chroma of 1 to 8. The C
horizon is sandy clay, clay loam, silty clay, or clay. The 10-to 40-inch control section
averages from 35 to 60 percent clay and from 35 to 65 percent silt. The underlying buried
horizon is variable in colors and textures.
COMPETING SERIES: There are no recognized competing series in this family
GEOGRAPHIC SETTING: The Yaupon soils are areas constructed from deposited
dredge spoil on the Lower Coastal Plain. The major portion of these areas are generally
convex with slopes from 0 to 6 percent with some areas ranging up to 15 percent.
GEOGRAPHICALLY ASSOCIATED SOILS: These are Axis, Bohicket, Bragg,
Carteret, Corolla, Duckston, Hobonny, Leon, Muckalee, Murville, Pactolus, and Wando
soils. Axis, Bohicket, and Carteret soils are very poorly drained and are flooded daily by
tides. Corolla Duckston, Leon, Murville, Pactolus, and Wando soils are sandy. Hobonny
soils are organic. Muckalee soils are coarse -loamy.
DRAINAGE AND PERMEABILITY: Somewhat poorly to moderately well drained
with soil surface runoff. Permeability is slow to very slow. Perched water can be
expected between layers of the sediments. There is an apparent water table at 2.0 to 4.0
feet in the winter and early spring.
USE AND VEGETATION: Most areas consists of idle land. The plant community is
loblolly pine, longleaf pine, wax myrtle, black cherry, yaupon, sweetgum, eastern
redcedar, live oak, water oak, myrtle oak, poison ivy, and muscadine grape.
DISTRIBUTION AND EXTENT: The Lower Coastal Plain of North Carolina, South
Carolina, Georgia, and Florida. The series is of small extent.
