MITIGATION PLAN FOR THE WHITE OAK CREEK SITE IN THE NEUSE RIVER
BASIN PIEDMONT PORTION OF CATALOGING UNIT 03020201
EXECUTIVE SUMMARY
Marsh Resources Inc. (MRI) with technical support from Rummel, Klepper &
Kahl, LLC is submitting for approval a 50.69-acre site in Cataloging Unit
03020202 (Upper Neuse Basin, Piedmont Physiographic Region). The site is
located on White Oak Creek in Johnston County, approximately 2.5 miles west of
Clayton, N.C. at 744 Winston Road (SR 1550). The site lies less than 900 feet
north of the proposed right of way for the U.S. 70 Clayton Bypass, T.I.P. Project
R-2552. The site is owned by MRI.
The site is currently being used as a horse boarding and breeding facility. It lies
in the lower reaches or elevations of four small drainage catchments that
originate offsite and drain across the site into White Oak Creek. The surface and
subsurface hydrology of these small catchments has been altered by the
roadside ditches beside Winston Road, ditching along the northwest corner of the
site, residential development offsite and ditches which drain the road system
supporting the residential development. In addition, eight ponds have been
constructed onsite. Over half of the site has been cleared for use as a horse
pasture, eradicating practically all the native woody vegetation.
The undisturbed wetland areas along White Oak Creek support a community
type best described by Schafale and Weakley (1990) as a Piedmont Swamp
Forest.
Based on a wetland delineation performed by RK&K the a
wetlands is 19.79 acres. A review of this delineation by the
Engineers (USACE) is scheduled for October 2, 2001. At
' Division of Water Quality will also review and determine the
channel onsite.

The State Historic Preservation Office and the N.C. Natural Heritage Program
have reviewed the site and determined that the project will have no impact on
archaeological or natural resources. The U.S. Fish and Wildlife Service has
requested a survey for the federally protected Dwarf Wedgemussel (Alasmidonta
heterodon), which is known to occur downstream in White Oak Creek near its
confluence with Swift Creek. The Service has suggested that a survey for the
mussel be conducted between Winston Road and Austin's Pond. This survey
has been scheduled and will be completed in October, 2001. The Service also
indicated in their February 21, 2001 letter that they were not aware of any
additional populations of federally protected species in the project area.

1.0 INTRODUCTION
Marsh Resources Inc. (MRI), with technical support from Rummel, Klepper &
' Kahl, LLC (RK&K) is submitting for regulatory approval a 50.69-acre mitigation
site on White Oak Creek in Johnston County, located approximately 2.5 miles
west of Clayton, N.C. at 744 Winston Road. The site is located in Cataloging
Unit 030202 (Upper Neuse Basin, Piedmont Physiographic Region).

2.0 SITE DESCRIPTION
2.1 Site Location
Comprising 50.69 acres, the site is located on the west bank of White Oak Creek,
immediately south of Winston Road (SR 1550) and north of Austin Pond,
approximately 2.5 miles west of Clayton, North Carolina. Winston Road runs in
an east-west direction between Amelia Church Road (SR 1553) and Cornwallis
Road (SR 1525). Figure 1 is the vicinity map and Figure 2 indicates the site's
location on the U.S. Geological Survey Garner 7.5 minute topographic
quadrangle.
White Oak Creek flows south from the site for approximately 2 miles to its
confluence with Swift Creek. The site is located in hydrologic unit (HU)
03020201110040 (USGS) or 17 (DENR), which is in a Priority Subbasin but not
within a designated Priority HU by the North Carolina Wetlands Restoration
Program. The site is bordered on the north and west by residential development.
The site's eastern boundary is White Oak Creek, which is currently buffered by a
mature swam p/bottom land hardwood.
The site lies less than 900 feet north of the proposed right of way for the U.S. 70
Clayton Bypass, T.I.P. Project R-2552 (Figure 2).
2.2 Site Ownership
The site is currently owned by Marsh Resources Inc. The site survey is located
in Appendix A.

2.3 Existing Use and General Conditions
The site is currently being used as a horse boarding and breeding facility. Up to
30 horses and colts are kept onsite. A large metal horse barn and a house with a
detached garage and various outbuildings are located beside the gravel road that
roughly bisects the site on its north-south axis. Cleared areas (approximately 32
acres) are used as pasture for the horses, which has resulted in soil compaction,
erosion, and nutrient-enrichment of nonpoint source stormwater runoff to White
Oak Creek.
The soil in the pastures has been compacted by the constant horse traffic,
' decreasing permeability and increasing the volume of stormwater runoff. Farm
pond construction, erosion gullies and ditching have further altered natural site
conditions.

White Oak Creek, the eastern site boundary, has been classified by the N.C.
Division of Water Quality as Class C, Nutrient Sensitive Water, (CNSW),
meaning it is protected for secondary recreation, fishing, wildlife, fish and aquatic
life propagation and survival, and agriculture. The nutrient-sensitive water status
requires additional nutrient management due to the vulnerability of the stream to
excessive vegetative growth. White Oak Creek is not on the 303(d) list of
impaired streams for the Neuse Basin.
2.4 Hydrology
The hydrology of the site is driven by two main components: the four small
drainage catchments that deliver water from offsite to the site from higher
elevation areas to the north and west and White Oak Creek and its associated
floodplain.
The site lies in the lower reaches or elevations of four small catchments which
originate offsite and drain across the site into White Oak Creek. The overland
flow (and probably to some extent the subsurface flow) of these small
catchments has been altered offsite by the roadside ditches beside Winston
Road, ditching along the northwest corner of the site, residential development
offsite and the ditches which drain the road system supporting the residential
development. Before development, stormwater in these catchments consisted
primarily of sheetflow which was largely absorbed into the soil before reaching
White Oak Creek. Road-building and the ensuing development, impervious
surface and ditching has resulted in an increase and concentration of stormwater
runoff in some areas. For example, the Winston Road ditch on the northern
border of the site concentrates stormwater flow from the road and offsite upland
areas and delivers it directly to White Oak Creek. Additionally, some stormwater
runoff from the roadside ditch across Winston Road is directed through a culvert
under the road and into the roadside ditch onsite. When flows are high in the
roadside ditch, the configuration of the ditch which runs beside the existing gravel
4

driveway onsite allows the capture of some of the roadside ditch flow and
conveys it across the site and into White Oak Creek.
The hydrology onsite has been altered in several ways. Very shallow, narrowly-
spaced (1 to 2 feet apart) rills were created in the higher elevations of the cleared
pasture areas to increase the site's ability to convey stormwater and to drain the
property. A ditch which varies in depth from approximately 1 to 5 feet borders
the gravel driveway from Winston Road south to just north of the horse barn,
where it turns east and runs down the hill for approximately 700 feet to the White
Oak Creek floodplain. Additionally, 8 ponds ranging in size from less than a
quarter-acre to approximately 2 acres have been constructed onsite. Six of the
ponds are situated adjacent to or in the White Oak Creek floodplain and 2 ponds
are located where an apparent intermittent stream (Johnston County Soil Survey,
NRCS, 1994) once flowed eastward across the site to White Oak Creek, just
south of the metal horse barn.
FEMA mapping indicates that about half of the site is within the 100-year
' floodplain, Zone A. This is the eastern portion of the property along White Oak
Creek. The western portion of the Site is not included in the 100-year or 500-
year flood zone. FEMA mapping is included in Figure 3.
I
u
fl
n

Using the Natural Resources Conservation Service hydrologic model TR-55, a water
budget was created for the site. One of the model functions is the estimation of
stormwater runoff quantity for a particular size storm. Using NRCS WETS precipitation
data for Clayton, NC the mean quantity of rain for a two-week storm was calculated and
input into the model. The volume of runoff expected from a two-week storm event was
predicted to be 0.73 ac-ft (31,900 ft) . This volume of water covers 1.46 acres to a
depth of 6 inches, or 2.20 acres to a depth of 4 inches. The following assumptions were
made in the model:
• The soils types within the offsite drainage areas are taken from the Soil Survey of
Johnston County, N.C. The onsite soils have been verified.
• The offsite residential areas within the drainage basins to the site are considered
to have an average lot size of 2 acres.
• The onsite runoff is modeled as a woods/grass combination in fair hydrologic
condition.
• The precipitation is based on average rainfall for the growing season (March 19-
Novemeber 15) per NRCS WETS precipitation data. The monthly average is
divided by two to determine the two-week average rainfall.
2.5 Soils

Four soil types are found onsite:
• Wehadkee loam (Wt)
• Rains sandy loam (Ra)
Goldsboro sandy loam, 0-2% slopes (GoA)
Wedowee sandy loam, 8-15% slopes (WoD).

The Wehadkee (Wt) soil series area is located in the lower eastern elevations of the site
along White Oak Creek. This hydric series is characterized by very deep, poorly
drained soil on floodplains formed by recent alluvial sediments. It is frequently flooded.
A very high percentage of the Wehadkee soils onsite remain undrained and support
maturing natural vegetation, or are overlain by open water in the ponds.
The Rains (Ra) soil series area is located in the northern portion of the property. This
series consists of very deep, poorly drained soils in broad interstream areas. These
soils, formed in loamy sediments, are frequently flooded. The majority of the Rains soil
onsite has been effectively drained.
Both the Wehadkee and Rains series are included on the Johnston County Hydric Soils
A list, which contains map units that are all hydric soils or have hydric soils as a main
component.
The Goldsboro (GoA) series area is located in the northern part of the site in slightly
higher topographic positions than the Rains soils. Goldsboro soil is characterized by
nearly level, deep, moderately well drained soils usually located in broad flats or slight
depressions. Goldsboro soil is listed on the hydric soils B list, indicating that it is a map
unit with inclusions of hydric soils or wet spots.
The Wedowee (WoD) soil series is located on the highest elevations in the western
portion of the Site. This soil is typically very deep and well drained. The Wedowee soil
series is not classified as a hydric soil.
' 2.6 Existing Vegetation and Plant Community Descriptions
Over half of the site has been cleared for use as a horse pasture, eradicating practically
all the native woody vegetation. A few small groups of individual trees remain in the
pasture areas, mostly loblolly pine (Pinus taeda), with a few scattered sweet gum

(Liquidambar styraciflua) and swamp chestnut oaks (Quercus michauxii). The
herbaceous vegetation in the drained wetland areas of the pasture is dominated by
planted fescue (Festuca spp.), but some remnant native wetland species persist such
as soft rush (Juncus effusus), tear thumb (Polygonum sagittatum) and knotweed,
(Polygonum hydropiperoides). Thistle (Cirsium spp.), an upland species, is also
common. A few scattered shrubs are found in the drained pasture area, mainly button
bush (Cephalanthus occidentalis) and tag alder (Alnus serrulata). The upland pasture
areas support various herbaceous species such as ragweed (Ambrosia spp.), goldenrod
' (Solidago spp.), briars (Rubus spp.), dog fennel (Eupatorium compostifolium),
nightshade (Solanum carolinense) and planted fescue.
The undrained wetland areas along White Oak Creek support a community type best
described by Schafale and Weakley (1990) as a Piedmont Swamp Forest. Schafale
and Weakley describe this community type as occurring on fine to medium-textured
' alluvial soils such as the Wehadkee series. The hydrology is palustrine, seasonally to
frequently flooded, and flooding may occur for relatively long periods. The vegetation
described consists of a canopy dominated by mixtures of flood-tolerant species such as
' sweetgum, red maple (Acer rubrum), black willow (Salix nigra), green ash (Fraxinus
pennsylvanica) and various oak and elm species. The community dynamics are
dominated by flooding for extended periods in many years. Sediment deposition is less
' than on the levee position, if present, and of finer texture. The periodic input of nutrients
makes these sites fertile, but growth is limited by the long periods of inundation or
saturation. Physical disturbance by flowing water is unlikely.
' The soils, vegetation and observed hydrology found onsite coincide well with this
description. The observed dominant species are sweetgum, red maple (Acer rubrum)
' and black willow (Salix nigra), with an occasional swamp tupelo (Nyssa sylvatica var.
biflora) and swamp chestnut oak (Quercus michuaxii) present.
2.7 Present and Future Development in the Area
As the population in the Raleigh-Durham area continues to experience rapid growth,
' development continues to expand beyond the boundaries of Durham and Wake
Counties. Johnston County has experienced rapid growth in the last decade, increasing
in population from 81,306 in 1990 to 121,965 in 2000, an increase of 50 percent
(Bureau of the Census, 2000).
' The property on the west border of the site is low-density residential with lots greater
than one acre (Figure 5 and Figure 8). The area directly north of the property is also in
low-density residential. To the northwest of the site a new church is being built and a
' subdivision, Winston Plantation, with 89 0.75-acre lots is under construction. All of the
property to the west and north of the site falling within the 4 catchments that drain
across the site are, or are subdivided for, development. To the east and northeast,
across White Oak Creek, the property is zoned as PUD designating Planned Unit
Development where residential development may continue down to 10,000 square-foot lots.

Mr. J. T. Peacock, Jr., P.E.
Associate
Rummel, Klepper & Kahl, LLP
5800 Farringdon Place, Suite 105
Raleigh, North Carolina 27609-3960
Dear Mr. Peacock:
Reference your letter of December 6, 2001, transmitting the December 6, 2001 plan for
the proposed White Oak Creek Wetland Mitigation Site, adjacent to White Oak Creek at SR
1550 (Winston Road), southwest of Clayton, in Johnston County, North Carolina. Reference
also my inspection of the White Oak Creek site with staff of Rummel, Klepper & Kahl, Marsh
Resources, Inc., NCDOT, and resource agencies on October 2, 2001.
Based on my site inspection and review of the plan, I have the following comments:
1. The January 14, 2002 comments from the U.S. Environmental Protection Agency are
enclosed for your information and response.
2. Cover letter: If the project proponent wants to pursue excavation in the potential
areas of former fill in the restoration area, a site inspection by the Corps of Engineers,
Wilmington District, will be necessary to verify the extent and depth of the filled areas. This
inspection can, and should, be coordinated before grading is started in these areas.
3. Page ii: Based on my site inspection, the information provided, and verbal
recommendations by resource agencies, it is not certain that the target hydrology can be
achieved in the proposed creation areas and restoration area R2 upslope of the excavated ponds,
as discussed in detail with Dr. Nunnery. Therefore, the mitigation proposal should be revised to
indicate that this acreage of the restoration area, and the creation acreages, will not be available
to be used for mitigation unless and until these portions of the site have met the hydraulic
success criteria to the satisfaction of the Corps.

4. Page 5, Section 2.5: This section and Figure 4 should indicate that Figure 4 is from
the soil survey, and reference the information in Section 4.4, Paragraph 2, on Page 13, to
indicate that the extent of soils in the soil survey have been generally field confirmed.
5. Page 13, Section 4.4, Paragraph l: This section indicates that creation area Cl will
contain berms to enhance infiltration, but the CONCEPTUAL SITE CONSTRUCTION PLAN
in Appendix F does not show any grading in area C1.
6. Page 13, Section 4.4, Paragraph 1: As discussed with Dr. Nunnery, the proponent
should ensure that the berm construction does not cause long-term ponding that will inhibit tree
survival.
7. Page 18, Section 4.8.1, and Appendix F: The plan should address the flow coming
into creation area C2 from the existing stream that comes into the western boundary of the site,
as well as the flows from the multiple breaches in the driveway ditch. Should flow spreaders or
other measures be used to dissipate the energy from these flows and prevent erosive forces from
creating new channels through the mitigation areas?
8. Page 18, Section 4.8.1, and Appendices E & F: Based on a conversation with Dr.
Nunnery, the existing driveway and pipe culvert between creation areas C2 and C3 will be
removed and graded to continue the creation area between the two areas. The
MITIGATION/PLANTING AREAS plan in Appendix E should be revised to indicate this.
Also, how will the site be accessed across connected areas C2 and C3 if this is done? It may be
best to put a culverted crossing at the upper end of C2 if access is necessary.
9. Page 19: Based on conversations with Dr. Kevin Nunnery of your staff, you have
had difficulty finding. a supplier for some of the tree species indicated, and are planning to
substitute appropriate species as coordinated with the North Carolina Wildlife Resources
Commission. Indicate the revised lists of species.
10. Page 19, last paragraph: The reference to Appendix D should be to Appendix E.
11. Page 20, Section 5.1: The plan should specify a hydraulic success criteria. The
Corps, requires that monitoring data must show that for each normal precipitation year within
the monitoring period, the site has been inundated or saturated within the upper 12 inches of the
soil for a minimum of 12.5% of the growing season. If the monitored areas do not meet the
12.5%, but achieve saturation for at least 5% of the growing season, the Corps and other
resource agencies will review the data and other site information and determine if wetland
mitigation is being achieved. WETS tables for Johnston County will be utilized to determine
normal precipitation years. If there are no normal precipitation years during the first five years
of monitoring, to meet performance criteria, the permittee will continue to monitor hydrology
on the site until it shows that the site has been inundated or saturated as described above during
a normal precipitation year.
2
12. Page 20, Section 5.1: As an alternative and as a supplement to meeting established
hydraulic criteria at the mitigation site, at the Corps' discretion, particularly in years without
normal rainfall, the mitigation site may be found to meet the hydrology performance criteria on
the basis of comparison of monitoring data taken from the site with monitoring data taken from
established reference sites approved by the Corps. The Corps retains the discretion to find that
the hydrology criteria are met if such monitoring data from the mitigation site and the reference
site are substantially the same. Reference sites should be established, should be reviewed by
the Corps, and the proponent should install monitoring gauges, before the start of the first
growing season after site construction. The reference sites should reflect the target hydrology
regime of the different areas of the site as closely as possible.
13. Page 20, Section 5.2: The plan should specify a vegetative success criteria. The
Corps requires that sample plots demonstrate that for each of the first three complete years of
monitoring, 320 target-species trees per acre have survived, such that at the end of three years,
320 three-year old target-species trees per acre have survived on the site, and, in years four and
five, 288 and 260 trees per acre, respectively, have survived on the site, such that at the end of
year five, 260 five-year old target-species trees per acre have survived on the site. If for any
monitoring year, vegetation survival is not favorable, as determined by the Corps, any remedial
action required by the Corps will be performed, the remedial action areas of the site will be
replanted, and the five-year monitoring period will begin again with year one in the remedial
action areas.
14. Page 20, Section 5.2: The plan should specify how the project proponent will deal
with nuisance species that may affect the growth of target species. Annual monitoring reports
should describe any aggressive growth in non-target species in both monitoring plots and other
areas of the site, and discuss possible remediation, if necessary.
15. Page 20, Section 5.2: The plan should specify a methodology for setting plot
locations.
16. Page 20, Section 5.2: The plan should specify that vegetative monitoring will be
conducted between June 1 and November 30.
17. Page 20, Section 5.2, Paragraph 2.: The plan should specify that the annual report
will be submitted to the Corps within sixty days of the end of the growing season.
18. Page 20, Section 6.0: The plan should include the following stipulations:
a. The project proponent will do a boundary survey of the 50.69 acre mitigation
site, and submit a copy of the survey to the Corps within 90 days after
construction of the site is completed.
3
b. An "as built" plan, which describes the completed mitigation project,
including variations from the original plan, location of sample plots and
hydrology gauges, number of individuals of each tree species within each sample
plot, location of monitoring wells, final project elevations, and photographs shall
be submitted to the Corps within 60 days of mitigation site completion.
c. The project proponent and subsequent property owners shall maintain the
White Oak Creek Wetlands Mitigation Site in its natural condition, as altered by
work in the mitigation plan or subsequent mitigation remediation, in perpetuity.
Prohibited activities within the mitigation property specifically include, but are
not limited to: the construction or placement of roads, walkways, buildings,
signs, or structures of any kind (i.e. billboards, interior fences, etc.); filling,
grading, excavation, leveling, or any activity that may alter the drainage patterns

Development LLC, a co-owner of the property, has stated that development plans are
progressing and that construction will begin in 2002.
The increase in impervious area associated with development will increase the
amount of runoff entering White Oak Creek. Preservation and restoration of
wetlands on the White Oak site will play an important role in treating stormwater
runoff before it enters White Oak Creek. White Oak Creek is documented as
having populations of the federally protected Dwarf Wedgemussel (Alasmidonta
heterodon) near its confluence with Swift Creek. Wetlands restored and created
at the White Oak mitigation site will help with the removal of sediment and
excess nutrients from stormwater runoff, and will be especially beneficial to
wetland and aquatic habitat downstream from the site, considering the growth in
the area.
The population in Johnston County is expected to continue its increase, with a
35% projected increase by 2010 (State Data Center, 2001). Given such growth
and development, wetland mitigation will provide an increasingly important role in
protecting the water quality of White Oak Creek.
3.0 CULTURAL / NATURAL RESOURCES AND PHASE 1 SITE ASSESSMENT
3.1 State Historic Preservation Office
The State Historic Preservation Office has reviewed the site and found no properties of
architectural, historic or archaeological significance onsite. Their letter, dated March 2,
2001, is included in Appendix B.
3.2 N.C. Natural Heritage Program
The North Carolina Natural Heritage Program stated that there was no record of rare
species, significant natural communities, or priority natural areas within two miles of this
site in a letter dated January 19, 2001 (Appendix B).
3.3 U.S. Fish and Wildlife Service

1

The U.S. Fish and Wildlife Service has reviewed the request for comments on the site
submitted by RK&K. The federally protected Dwarf Wedgemussel (Alasmidonta
heterodon) is known to occur downstream in White Oak Creek near its confluence with
Swift Creek. The Service has suggested that a survey for the mussel be conducted
between Winston Road and Austin's Pond. This survey has been scheduled and will be
completed in October, 2001. The Service also indicated in their February 21, 2001
letter (Appendix B) that they were not aware of any additional populations of federally
protected species in the project area.

3.4 Phase 1 Site Assessment
t A detailed Phase 1 site assessment was performed on September 10-11, 2001 to
determine if there are any potential environment hazards onsite. A copy of the report is
included in Appendix C. The final conclusion of the assessment was that there are no
environmental hazards located on this property.
4.0 CONCEPTUAL MITIGATION DESIGN AND CONSTRUCTION
' 4.1 Present and Future Wetland Ecological Functions
' Wetlands perform certain ecological functions in unique ways. These functions are both
inherent characteristics of wetlands, and the result of wetland function interactions.
Wetland functions include hydrologic flux and storage, biological productivity,
' biogeochemical cycling and storage and community/wildlife habitat (Richardson 1994).
The present condition of wetland functions onsite can be described as being drastically
altered from their natural state. The natural hydrologic flux and storage of the site has
been modified by ditching, drainage, soil compaction and the creation of artificial ponds.
The first three alterations increased stormwater runoff from large areas of the site and
the fourth alteration impounded water on areas not previously wet. The total volume
and the rate of stormwater runoff has been increased, thus decreasing the site's ability
to attenuate stormwater runoff. The presence of the horses, coupled with the
' compaction of the soil has undoubtedly resulted in nutrient enrichment of White Oak
Creek, a CNSW-classified stream.
' Approximately half of the site has been cleared of its natural vegetation, decreasing
primary production and diversity of the flora. The loss of wetland hydrology and primary
productivity in the cleared wetland and upland areas has had a negative effect on
' biological productivity.
Anaerobic conditions in wetland soils have been shown to transform available forms of
' nitrogen and phosphorus to unavailable forms, improving water quality. This
biogeochemical cycling and nutrient-filtering function is lost when wetlands are drained
as those have been onsite. Another important biogeochemical function, dissolved
' organic export, is an important food source for microorganisms in the downstream
waters, which are themselves important food sources for organisms higher in the food
chain. The dissolved organic export function is largely lost when wetlands are drained.
When forested wetlands are drained and converted to pasture, the wetland plant
community and the habitat for organisms which are adapted to it is essentially lost.
The proposed mitigation efforts will restore hydrologic flux and storage, biological
production, biogeochemical flux and storage and community/wildlife habitat to a much
more natural state.

4.2 Jurisdictional, Preservation and Proposed Enhancement Wetlands
' The National Wetlands Inventory (NWI) map indicates approximately 19.4 acres of
Palustrine, Forested, Broadleaf, Seasonally Flooded wetlands on the site (Figure 6).
However, based on a wetland delineation performed by RK&K the area of jurisdictional
wetlands is 18.39 acres. A map of the delineated wetlands (preservation and
enhancement areas) is found in Appendix D. The delineated wetland areas consist of
forested palustrine swamp along White Oak Creek (preservation area), and areas of
emergent marsh in the pasture (E1 and E2) which will be proposed for enhancement
credit. The conceptual mitigation areas for the entire site are also depicted in Appendix
D.
4.3 Proposed Restoration Areas
The areas of the site exhibiting redoximorphic depletions and hydric soil colors (chroma
of 2 or less) within 12 inches of the surface were delineated by Kevin Nunnery of RK&K,
a Licensed Soil Scientist in the State of North Carolina (Figure 7 and Appendix D,
areas R1, R2 and R3). The areas occur in the northern pastured area of the site, in
and adjacent to the NRCS-mapped Rains unit. Two existing ponds P1 and P3, adjacent
to E1 and a portion of the large pond just south of E1 (P5b, Figure 7) are included in this
area. Restoration area R4 is composed of historic floodplain areas that have been
inundated by pond construction (P8) or filled in to create those ponds. Restoration area
R5 is another area that was part of the floodplain wetland but has been filled in at some
time in the past. Restoration areas R6 and R7 are small ponds contained within E3.
The total restoration area is 9.21 acres
' Restoration credit is proposed for all or portions of 7 of the 8 excavated ponds onsite
based on the intent of filling them and restoring the natural topography. The small pond
located on the west side of the driveway is not located in an area where hydric soils
likely occurred before pond construction, and will be used as a wetland creation area.

4.4 Proposed Creation Areas
Four areas of wetland creation are proposed. Creation areas C2, C3 and C4
(Appendix D) are located in areas where there are existing ponds (P5a, P6 and P8 in
Figure 7). Jurisdictional hydrology will be attained in these areas by utilizing the flow
from intermittent and ephemeral channels and by lowering the elevation of the soil
profile with respect to the floodplain of White Oak Creek. Small berms will be
constructed perpendicular to the direction of flow at various locations to enhance
infiltration of surface runoff. Creation area C1 will utilize water from the roadside and
driveway ditch and will also contain berms to enhance infiltration.
At six different locations within proposed creation areas, soil cores were taken to a
depth of six feet (Figure 8), to determine the texture and color of the underlying soil

horizons. In three of the cores, (numbers 1,2, and 6) the texture of the soil below 10-15
inches was sandy clay. In cores 3, 4 and 5 a loamy horizon of varying depths occurred
below 15 inches. In core 3, there was a sandy clay horizon from 24 to 65 inches. In
core number 4, the sandy clay texture began at 8 inches and continued to 72 inches,
with a six-inch layer of sandy loam located between 32 and 38 inches. In core number
5, sandy loam changed to sandy clay at a depth of 42 inches and continued to 72
inches. A summary of the core data is included in Appendix F.
4.5 Existing House and Garage
The existing house and garage will be removed during the construction phase of the
project.
4.6 Wetland Reference Areas
The owners of the property directly east across White Oak Creek (Ashley Turner
Development, LLC and M.A.L. Properties, LLC) have granted permission to locate
wetland reference plots on their property. Several proposed sites have been chosen for
approval.
4.7 Mitigation Summary
Four types of mitigation are proposed at the site, as shown in Appendix D: restoration,
creation, enhancement, and preservation.
The restoration areas include the drained hydric soils areas and portions of the
excavated ponds and their borders minus the areas contained in the enhancement
areas E1 and E2. One additional restoration area (135) is located at the south of the
site, where fill that has been placed beside White Oak Creek will be removed and the
natural topography of the wetland restored.
Four wetland creation areas will be located onsite, three of them utilizing the excavation
performed to create ponds P5a, P6 and P8 (C2, C3 and C4). One additional creation
area (Cl) will be constructed in the northern part of the site, east of the existing
driveway.
The enhancement areas will be comprised of the delineated wetland areas E1 and E2,
located in the pasture area. These wetlands will be revegetated with appropriate
wetland woody species.
The preservation areas will be comprised of the delineated forested wetland areas
adjacent to White Oak Creek.
The upland areas onsite will be restored and will function as an upland buffer for the
mitigation areas by planting with appropriate Dry-Mesic Oak Hickory Forest woody
17
0

species (Schafale and Weakley, 1990) such as northern red oak (Quercus rubra) and
white oak (Q. alba).

' 4.8 Conceptual Mitigation Design Description
' 4.8.1 Restoration of Natural Grade and Surface Hydrology
The natural grade and surface hydrology of the proposed project site have been
extensively altered by the construction of the driveway and its culverts and ditches, the
excavation of eight ponds throughout the site and the ditching activities in the northern
pastured areas. Rectification of the hydrologic changes made to the drainage patterns
' that likely existed before development of the site will require the movement of soil
onsite. Important features of the proposed conceptual mitigation design include:
• Removal of the fill used to dam all ponds,
• Redistribution of the fill to previously excavated areas of the ponds and
main ditch located beside the existing horse barn,
• Re-establishment of natural contours where ponds are currently
' located based on existing elevations,
• Fine grading to merge elevations where ponds have been filled to the
surrounding, undisturbed contours,
• Re-establishment of natural microtopography using 6-inch earth ridges
' to promote stormwater infiltration into the soil across wetland
restoration areas of the site, and
' Breaching of the driveway ditch in multiple locations to allow
stormwater to flow more evenly across the northern part of the site,
with less erosive force.
' The conceptual mitigation design plan and the construction plan (Appendices D and E)
graphically depict how the proposed activities will remove the dams used to create the
18

ponds onsite and use the material to return smoothly sloping, natural gradients to the
site. Water entering the site from the driveway ditch will be allowed to flow across the
site from multiple breaches in the ditch between Winston Road and the terminus of the
ditch near the existing horse barn. The driveway in its present location will be
maintained for access across the site for approximately 500 feet.
4.8.2 Vegetation
The entire cleared pasture area will be replanted with woody vegetation as soon as the
completion of construction allows and the site can be prepared for planting.
' The upland buffer restoration areas (Wedowee and Goldsboro soils) will be planted with
vegetation characteristic of a Dry-Mesic Oak Hickory Forest, as described by Schafale
and Weakley (1990). A map of the mitigation areas is included in Appendix D.
' Dominant species described by the authors include white oak (Quercus alba), northern
red oak (Quercus rubra), swamp chestnut oak (Quercus michauxii), pin oak (Quercus
palustris), and cherrybark oak (Quercus falcata var. pagodaefolia).

The wetland restoration, creation and enhancement areas will be planted with woody
species not necessarily classified by Schafale and Weakley (1990) as being
components of a Piedmont Swamp Forest. This is because the regulatory agencies
generally require wetland mitigation planting plans to include hard or soft mast-bearing
tree species as a food source for game species, and some of these species may not be
listed as a component of the target community type. For this reason the species
planted in the wetland restoration and creation areas will be comprised of overcup oak
(Quercus lyrata), swamp chestnut oak (Quercus michauxii), swamp tupelo (Nyssa
sylvatica var. biflora) and green ash (Fraxinus pensylvannica). Shrub species which
produce wildlife food will also be planted such as silky dogwood (Corpus ammomum),
elderberry (Sambucus canadensis), and buttonbush (Cephalanthus occidentalis). The
final planting plan will also be based on dominant vegetation in the reference area.
4.9 Construction
Construction will be performed by a contractor licensed and insured in the State of
North Carolina. All construction and planting will be monitored by the MRI/RK&K team
for quality control and for assurance that the project schedule is maintained.
5.0 MONITORING PLAN
5.1 Hydrologic Monitoring
Sixteen groundwater monitoring gauges will be used to monitor groundwater levels in
the mitigation areas of the site. One gauge will be placed within each of the four small
pond restoration areas (P1-P4). Three wells will be placed in R3 west of the
enhancement area on a transect from the edge of the enhancement area E1 to the
19

' existing driveway. Three wells will be placed in C3, equally spaced along a north-south
transect. One well will be placed in R1, R4, R5, C1, C2 and C4 respectively. The
' groundwater levels recorded at each of these wells will be compared to the groundwater
levels recorded at the reference site.
' 5.2 Vegetation Monitoring
A total of 19 permanent 1/10th acre plots will be established across the site to monitor
the survival, growth, and species composition of the vegetation established in the
mitigation areas. Two plots will be established in each of the 8 small pond/mitigation
areas. Three additional plots will be located in the area not associated with
pond/mitigation areas. In the event that the planted seedlings experience mortality or
herbivory to the extent that the target number of trees per acre is not achieved,
seedlings will be replanted in areas where necessary.
An annual report will be generated documenting groundwater levels across the site and
vegetation growth, survival and species composition. This report will indicate whether
I the restoration, creation and enhancement areas are exhibiting jurisdictional hydrology
and will describe the status of the vegetation in those areas.
' 6.0 FINAL DISPOSITION OF THE PROPERTY
The property is now owned by MRI. Upon approval of the mitigation plan, the property
will be offered for sale to the NC Department of Transportation (NCDOT). The NCDOT
will retain ownership of the site until all mitigation activities are completed and the site is
determined to be successful. A conservation easement or other restrictive covenant wil
' be established for the property to ensure that it is managed for the purposed of wetland
mitigation in perpetuity.

Dear Ms. Paulson:
The U.S. Fish.and Wildlife-Service(Service) has reviewed your request for comments regarding
federally listed species located on or near a potential wetland mitigation site in Johnston County,
North Carolina. According to the information you provided, this site is located on White Oak .
Creek between SR 1550 and Austin's Pond. The federally protected Dwarf Wedgemussel
(Alasmidonta heterodon) is known to occur downstream in White Oak Creek near its confluence
.with Swift Creek. Since there is potential for Dwarf Wedgemussel to occur in the'section of
I White Oak Creek that includes the proposed mitigation site, 'the Service suggests that surveys
for this species be conducted between SR 1550 and Austin's Pond. In addition, please consider
that any activities that occur in White Oak Creek have the potential to impact mussel populations
in lower White Oak Creek and Swift Creek.
The Service is not aware of any additional populations of federally protected species in the
' project area. Please contact Mr. Dale Suiter at [phone], extension 18, or
Dale Su.iter lffws,.gov if you have any additional questions regarding this project.
Sincerely,
II ?. /o 0

White Oak Creek Mitigation Site
Environmental Due Diligence
September 18, 2001
This environmental due diligence report has been prepared for the Marsh Resources'
White Oak Creek Mitigation Site located in Clayton, North Carolina. The purpose of this
report is to identify any environmental-related issues that could impact the development
of the mitigation site, as planned.
The site evaluation was performed at the request of Marsh Resources and conducted on
September 11, 2001. The evaluation includes a site walk of the 50.69-acre site, a
preliminary assessment of White Oak Creek, and an inventory of materials onsite that, at
a minimum, may require special handling by contract personnel.
Executive Summary
A preliminary feasibility study has already been prepared by the consulting engineering
firm (RK&K Engineers, Inc. ) contracted to perform the White Oak Creek Mitigation
survey and design work. Observations and research conducted in preparation of this
report concurs with all aspects of the study, with the addition of several minor points:
(Attached with this report is a copy of the feasibility study)
• Section III. Existing Conditions, Item B, Flood Data:
' A large subdivision (Winston Plantation) is being developed immediately upstream of
the White Oak Creek Mitigation Site. The hydraulic load from diffuse surface runoff,
de minimis concentrations of fertilizers and pesticides, and overflows of the sewage
' collection system during heavy rains may occur.
It should be noted, however, that this potential exists regardless of whether the
' wetland mitigation occurs, or not. It is conceivable that the White Oak Creek site will
buffer the impact of such conditions, should they occur.
' • Section III. Existing Conditions, Item E, Hazardous Materials:
A cursory review of materials contained at the residence was made during the site
' walk. Aside from the construction debris resulting from razing the house and garage,
various gasoline cans, oil, and paint containers were observed in the garage and
around the house. Should these materials be full, or partially full, care must be taken
t to manage the waste materials appropriately.

' White Oak Creek Mitigation Site
Environmental Due Diligence
' September 18, 2001
' One section of the garage was not observed since the door was secured with nails.
This area should be observed prior to razing the garage structure. Should it contain
' regulated materials, care should be taken to manage the materials appropriately.
Most construction materials observed can be managed as construction debris at a
' municipal landfill at a cost that should not exceed $2,000 - $5,000. [Other
consideration is to contact the local fire department and offer using the site for fire
training purposes, at no cost.]
' • Air permits
' Open burning is prohibited in most counties without a permit. Insure the permit is
obtained from the county if the site plan includes open burning of stumps and other
vegetation.
' Soil Erosion / Permits
Soil barriers, such as silt fencing, to prevent soil/sediment from eroding into White
Oak Creek is imperative and shall be included in the construction plans. If a county
permit is required for disturbing greater than five acres, insure a permit is obtained
' prior to construction.
• Based on the number of mosquitoes and other pests encountered onsite, the
' development of this site to a functional wetland should aid in the control of the pests.
Aside from these precautionary measures, no observations were made that should hamper
' the development of this site.

FINAL REPORT ON THE CONSTRUCTION, VEGETATIVE PLANTING AND
HYDROLOGIC MONITORING OF THE WHITE OAK CREEK WETLAND
MITIGATION SITE AT 744 WINSTON ROAD, JOHNSTON COUNTY, NORTH
CAROLINA
JUNE, 2002
1.0 INTRODUCTION
The White Oak Creek Wetland Mitigation Site is located on the west side of
White Oak Creek at 744 Winston Road in Johnston County, North Carolina (see
vicinity map, Figure 1). The 50.69-acre site is approximately 2.5 miles west of
Clayton, N.C., in Cataloging Unit 030202 (Upper Neuse Basin, Piedmont
Physiographic Region). Marsh Resources Inc. (MRI), with technical support from
Rummel, Klepper & Kahl, LLP (RK&K) acquired, designed and monitored the site
for use as compensatory mitigation for wetland impacts incurred by the North
Carolina Department of Transportation in the area. The following report contains
an As-Built survey plan (Appendix A), summarization of construction activities,
vegetative planting summary (species and stems by project area) and hydrologic
monitoring data for the beginning of the growing season (March 18, 2002)
through May 23, 2002.
2.0 SITE LOCATION AND DESCRIPTION
Comprising 50.69 acres, the site is located on the west bank of White Oak Creek,
immediately south of Winston Road (SR 1550) and north of Austin Pond,
approximately 2.5 miles west of Clayton, North Carolina (Figure 1). Winston
Road runs in an east-west direction between Amelia Church Road (SR 1553)
and Cornwallis Road (SR 1525).
White Oak Creek flows south from the site for approximately 2 miles to its
confluence with Swift Creek. The site is located in hydrologic unit (HU)
03020201110040 (USGS) or 17 (DENR), which is in a Priority Subbasin but not
within a designated Priority HU by the North Carolina Wetlands Restoration
Program. The site is bordered on the north and west by residential development.
The site's eastern boundary is White Oak Creek, which is currently buffered by a
mature swamp/bottomland hardwood.
3.0 CONSTRUCTION SUMMARY
Site construction began in the second week in January, 2002. All construction
work was perfomed by Geo-Con Inc. The primary tasks and construction
sequence were as follows:
• the silt fence was installed,
• the existing ponds were drained,

• the dams were removed,
• the ponds were back-filled where necessary,
• the existing buildings were removed,
• grading was done to restore the natural topography of the site (Please see
As-Built Plan in Appendix A),
• berms were constructed in the wetland creation areas, and were then
seeded with wildlife mix and covered with matting,
• the ditch paralleling the driveway was graded to more evenly distribute
stormwater across the site,
the site was planted and seeded.
Construction activity in the restoration areas was limited to ripping the soil on
two-foot centers. This activity was approved by Mr. Eric Alsmeyer of the U.S.
Army Corps of Engineers (USACE).
The upland buffer areas were ripped also, on two-foot centers.
The creation areas were brought back to a natural
constructed to slow stormwater runoff and enhance
the soil. The berms were seeded and matting was
laterally approximately one foot on each side.
Construction was completed on March 16, 2002.
4.0 TREE PLANTING SUMMARY
grade and then berms were
the infiltration of water into
placed over them extending
Trees were planted in the Restoration, Creation and Enhancement areas on a
10' x 10' spacing (435 trees per acre) and in the Upland Buffer Restoration on a
12' x 12' spacing (302 trees per acre). Because of limited availability of planting
material, changes were made to the species list designated in the December 6,
2001 Mitigation Plan. All species changes were approved by the regulatory
agencies in phone discussions with RK&K. Planting was performed by
Environmental Quality Resources, Inc. (EQR) of Gaithersburg, Maryland. Eric
Goodrich was the project manager. EQR completed their planting operations on
March 19, 2002. On a subsequent site review by NCDOT and USACE on April
10, it was pointed out that EQR had not planted a small area in the Enhancement
area E3. RK&K planted that area on April 18 with 150 Nyssa sylvatica var.
biflora, which completed the planting task for the site.
On May 3, 2002, MRI provided NCDOT with a letter guaranteeing 90% survival
of planted species after the first year.
Table 1 contains the planting summary by species and area for the Site which
EQR completed (it does not reflect the additional RK&K planting of E3).

Vegetation monitoring plots (50' x 50' or 0.057 ac) were installed using NCDOT
right of way posts in locations selected by the USACE, and are shown on the As-
Built plans.
5.0 GROUNDWATER MONITORING SUMMARY
Thirty-six groundwater monitoring gauges were installed onsite by March 19, the
official beginning of the growing season based on WETS data (50% probability
that the growing season occurs between the dates in the 280 F or higher column,
March 19 - November 15). Additionally, two reference gauges were installed on
private property on the east side of White Oak Creek in a natural area. One was
located in the riparian wetland farther upslope from the creek to correspond with
areas on the Site with higher elevation. The remaining well was installed farther
downslope, nearer the creek channel, to correspond to the lower elevation areas
on the Site. For locations of the gauges, please refer to the As-Built plan in
Appendix A (the reference gauges were located using both total station and GPS
and the coordinates given to NCDOT). Permission to install and maintain the
reference wells was granted by Mr. Jim Middleton of Performance Properties in a
letter dated March 14, 2002, which is included in Appendix 1. The gauge data is
summarized in Table 2.
As suggested by the USACE, numerous gauges were installed onsite- 17 in the
creation areas and 18 in the restoration areas. The intent was to maximize the
monitoring coverage of the site, and minimize the size of areas where a well
indicates that jurisdictional hydrology has not been achieved, where present.

Based on the WETS data, the growing season for the Clayton area is 241 days.
The USACE 1987 Wetland Delineation Manual states that groundwater must be
within twelve inches of the soil surface from between 5% and 12.5% of the
growing season on consecutive days (at a minimum) for jurisdictional hydrology
to exist. Based on these criteria, groundwater must be within 12 inches of the
soil surface for 12 to 30 days consecutively for the area to be considered a
wetland. Five creation area gauges and twelve restoration area gauges met the
minimum, 12-day criterion.
Rainfall data for the spring of 2002 was obtained fror
Research Station, located on U.S. 70 less than three
the station from which the WETS data is compiled.
WETS climatic data are summarized in Table 4.

May (1 s -29) 1.16 3.88 2.83 -2.72
The WETS 30% Chance Will Have Less Than column in Table 4 indicates at the
30% probability level the amount of rain predicted to fall when actual rainfall is
less than the computed precipitation mean from 1961-1990. For example, the
WETS monthly precipitation average for February is 4.10 inches. There is only a
8

' 30% chance that actual rainfall amounts will be as low as 3.07 inches for the
month of February, based on precipitation data recorded at the Clayton station
' from 1961-1990.
Based on the WETS monthly averages and actual precipitation for January-April,
2002, actual precipitation is approximately 6.5 inches less that the expected
average (1961-1990) and for January-May, the deficit was 9.18 inches.
Ponded areas in Creation Areas 3 and 4 were surveyed on May 6, 2002. Stakes
were placed at a point behind each berm where the water depth was one-half the
total depth behind that particular berm, as directed by the USACE (the surface
water monitoring plan is located in Appendix B). Stakes were also located in
deeper ponded areas and as locations for points to take photographs. The depth
of the water at these stakes was measured periodically begining May 3, 2002. In
order to qualify as a jurisdictional wetland area, ponded water areas have to be
inundated for 5 to 12.5% of the growing season, or 12-30 days consecutively.
' 6.0 NCDOT-APPROVED AREAS WHERE JURISDICTIONAL HYDROLOGY
HAS BEEN ACHIEVED OR IS EXPECTED TO BE ACHIEVED IN
' FUTURE MONITORING YEARS
A field review of the site was conducted on June 5, 2002 by the following
' persons:
NCDOT
David Schiller
' . Jim Hauser
Elizabeth Lusk
• Phillip Todd
RK&K
• Tommy Peacock
Kevin Nunnery
• Howard Woodall
• Nancy Daly
• Pete Stafford
MRI
• Jamie Ingram, Greenhorn and O'Meara, for Rich Mogensen
' All areas of the site were reviewed and the gauge data to date were discussed.
On June 7, 2002 RK&K received an email from Phillip Todd that summarized
NCDOT's analysis of the construction, planting and monitoring of the site. The
' four comments were as follows:
' 1) RK&K should recalculate the areas noted as R4 and C4. We believe the
top edge of the wetland area should be the 200-foot elevation. The area
should be "split" between restoration and creation per the negotiated

agreement between RK&K, USACE and DWQ during a field visit earlier in
the project history.
' 2) We believe Marsh/RK&K should be given "credit" for the hatched areas as
noted in the plans provided to the NCDOT at the meeting on June 5
(except for the areas we have asked RK&K to correct in item #1).
' 3) We believe Marsh/RK&K should be given "credit" for R8 area. The data
collected over the past month in particular have shown the hydrology to be
returning to this area despite the drought we are currently in.
' 4) The remaining areas we are not certain that wetland hydrology would be
met, particularly in the areas of Gauge #15 and #30. We recognize that
the region is currently in a drought, but there is currently not enough data
to suggest the areas will be wetlands in the future. Therefore, we
recommend the contract with Marsh and RK&K remain open, more data
collection and a decision about whether "credit" should be given for the
non-hatched areas reserved for the future.
' Based on this communication, the mitigation areas accepted by NCDOT as
achieving hydrologic success or those which are expected to achieve success in
the future are presented in Table 5. These areas were calculated from the
' corrected as-built plans as directed in comment #1. After field review and
survey, the upland boundary for C4 was determined to be the 202-foot elevation.
