EXECUTIVE SUMMARY
Resource Southeast, Ltd. was retained by the North Carolina Department of
Transportation, Planning and Environmental Branch, to prepare a mitigation plan for the
proposed Casey Tract wetland mitigation site. The site consists of approximately 24.3 acres and
is located in Currituck County, at the town of Sligo, North Carolina, on the north side of NC 168
(Figure 1).
Development of the mitigation plan included the review and analysis of existing
information, a wetland delineation, a natural communities assessment, an investigation of potential
hazardous materials, cultural resources, and threatened and endangered species, a surface
hydrology/water budget analysis and an evaluation of the data developed and preparation of the
plan. Each of these specific areas of study are addressed in this report. This report does not
constitute a final design for the mitigation plan and does not include final construction drawings
and planting specifications; these will be prepared following approval of this mitigation plan.
Resource identified approximately 16 acres of the site as being jurisdictional wetland
including 12 acres of coastal marsh which fall under the jurisdiction of the North Carolina
Division of Coastal Management and 4 acres of forested and swamp forest wetlands. Mr.
Richard Watts of the NC Division of Coastal Management confirmed the coastal marsh
delineation. Resource also met on-site with Mr. Mike Bell of the U. S. Army Corps of Engineers,
(Wilmington District), who concurred with the delineation of jurisdictional wetlands. An
approximately 6 acre complex of farm fields (4.9 acres), house, roads and timbered non-wetlands
(1.1 acre) are designated as prior converted (PC) wetland as defined by the United States
Department of Agriculture - Consolidated Farm Services Agency (ESDA - CFSA). The
remaining 2.4 acres consist of a forested upland area which will be preserved.
Neither the study area or other properties within the appropriate search distance have
been listed as a National Priority List (NPL) Superfund site, Comprehensive Environmental
Response, Compensation and Liability Information System (CERCLIS) site, an Inactive
Hazardous Waste Site, a permitted Resource Conservation and Recovery Act (RCRA)
Treatment Storage and Disposal (TSD) facility, a permitted RCRA Hazardous Waste
Generators or a permitted landfill. No cultural resources or threatened or endangered species
have been identified on the site.
Data developed for the surface hydrology/water budget analysis included the installation
of four observation wells, the performance of infiltration tests at five locations, the testing of two
undisturbed (Shelby tube) soil samples for classification and one for vertical permeability, the
compilation and evaluation of precipitation data along with the calculation of potential surface
runoff and evapotranspiration losses. The water budget analysis indicated that insufficient water
is currently available to the mitigation site (the prior converted wetland) for coastal marsh
hydrology. This is due to surface elevations which cause surface runoff losses.

creation of coastal marsh on-site. An additional Reference Ecosystem has been identified on the
Ballance Farm mitigation site which has similar elevation, topography, vegetation and soils as the
on-site coastal marsh; two observation wells have been installed in the Ballance Farm Reference
Ecosystem. It is proposed to establish conditions (topographic, hydrological and vegetative) for
the coastal marsh creation area as close as possible to the conditions in the Reference Ecosystems.
The proposed mitigation plan involves excavation of the PC field to elevations which
approximate those of the existing adja ent coastal marsh Reference Ecosystem, which should
significantly reduce infiltration loose .existing ditches on the south side of the property will be
extended between the nearby creeks and the mitigation site
extended to establish hydro oin co
such that the hydrology of the site will be dominated by the tidal influence of adjacent creeks.
Vegetation proposed for the coastal marsh creation area includes species which occur in the
adjacent existing marsh including sawgrass, which is proposed to be transplanted from the existing
marsh. In conjunction with development of the mitigation area the existing upland hardwood
forest will be preserved as a buffer between the mitigation area and the existing swamp forest to
ensure site grading activities will not adversely impact the existing wetland hydrology. This
preservation will also enhance the mitigation site by establishing zonation of habitats.
The NC 168 widening project (R-2228) will impa t 2. acre of coastal marsh wetland
and 22 acres of jurisdictional wetlands along the project corridor. Using the US EPA's mitigation
guidelines for mitigation credits, a total of 3.58 credits can be obtained by the proposed mitigation
project on the Casey Tract site. Of this total, 1.83 credits (5.5 acres) will be obtained through the
creation of a tidal freshwater marsh with species similar to the adjacent marsh as well as impacted
marsh species. The Casey Tract will also provide 0.4 credits through the preservation of 4.0 acres
of existing wetland, 0.16 credits through the preservation of upland forest (at a ratio of 15:1), and
1.19 acres through preservation of the existing coastal marsh.
The U.S. Army Corps of Engineers Mitigation Planning Checklist has been completed for
this project, and is included with this report (Appendix J).

1.0 INTRODUCTION
1.1 Project Description
The North Carolina Department of Transportation (NCDOT) is currently proposing to
widen NC 168 in Currituck County from the existing two lane highway to a multi-lane facility
from Barco to the Virginia state line at Moyock. The widening project will cross several streams
' impacting approximately 22 acres of jurisdictional wetlands, as defined by the U.S. Army Corps
of Engineers (USACOE). In addition, 2.4 acres of coastal marsh wetland, as defined under the
North Carolina Coastal Area Management Act (CAMA) will be impacted by this project.
The Casey Tract has been selected by NCDOT as a mitigation site for some of the wetland
impacts that will occur due to the highway widening project. The site consists of approximately
' 24.3 acres. This includes a 6.0 acre area consisting of 1.1 acres of house, driveway, and timbered
non-wetland and 4.9 acres of farm field designated as Prior Converted (PC) wetland; 11.9 acres
of coastal marsh, 4.0 acres of jurisdictional wetland (including 3.2 acres are swamp forest and 0.8
acres are other wetland), and 2.4 acres of forested upland. The upland forest around the field
slopes quickly into a band of forested wetland which then grade to a large area of coastal marsh
wetland along Cowells Creek and Buckskin Creek. The goal of this project is to mitigate for part
' of the coastal marsh impacts by creating coastal marsh wetland from PC fields. In addition to the
wetland being created, approximately 4 acres of forested wetland and 2.4 acres of forested
uplands on-site will be preserved.
To achieve stated goals NCDOT proposes to grade the PC fields and part of the old
home site to an elevation that approximates the Reference Ecosystem, to establish hydrologic
connection with existing surface waters along the southern property boundary, and to plant the
site with coastal marsh vegetation similar to those species found in the Reference Ecosystem and
' those being impacted by the NC 168 widening project. An existing forested upland area will
remain in place to serve as a buffer between the graded PC fields and the existing forested
wetland.
1.2 Purpose
' This report describes the results of a wetland delineation, a natural communities report, a
water budget for the site, an investigation of potential hazardous materials and cultural resources,
and preparation of the mitigation plan. This report does not constitute final design for the
mitigation plan and does not include final construction drawings and planting specifications. Final
design and construction drawings will be prepared following approval of this mitigation plan.
Recommendations made in this report are based on the analysis of relevant existing published data
and data collected in field investigations.

1.3 Study Area
' The Casey Tract lies in Currituck County at Sligo on the north side of NC 168 between
Buckskin and Cowells Creek (Figure 1). The site is located in the extreme northeastern Coastal
' Plain physiographic province of North Carolina. The project site is located in a rural but
potentially high growth corridor in the central portion of Currituck County.
The Casey Tract is situated along Buckskin and Cowells Creeks and the coastal marsh on
the property extends to the confluence of the creeks. Both creeks are tributaries of Tull Creek
which flows into Tull Bay at the northern end of Currituck Sound. Buckskin and Cowells Creek
' are typical blackwater coastal streams with occasional tidal influence from the wind driven tides in
Currituck Sound. The streamwater is acidic, low in mineral sediment and colored by tannins.
Both creeks are characterized by meandering channels approximately 150 feet wide with a number
' of smaller tributaries, and the creek banks are lined by coastal marsh and cypress trees.
The tract is essentially flat with the natural topography ranging from approximately 0.5
' feet above mean sea level (msl) at the coastal marsh edge to 4 feet above msl at the center of the
PC field. An old homesite with a barn and trees occupies the central portion of the property and
is surrounded by the farm field. Approximately 4.9 acres of the site has experienced agricultural
' activities, including some man-made ditches. Canals adjacent to NC 168 connect the PC fields to
both creek channels. Existing site conditions are illustrated in Figure 2.
' 1.4 General Methodology
Information sources used to prepare this report include: U.S. Geological Survey (USGS)
t 7.5 minute series topographic map of the Currituck quadrangle (1982); Soil Conservation Service
(SCS, 1982) Soil Survey of Currituck County; Prior Converted Wetland Determination
' (Consolidated Farm Services Agency, 1988); Geologic Map of North Carolina (1985); Property
Map of Currituck County (Currituck County Tax Office, 1985). Research using these resources
was conducted prior to the field investigation.

2.0 WETLAND DELINEATION AND NATURAL COMMUNITIES
2.1 Purpose and Methodology
The purpose of this section of the report is to describe the natural communities and
wetland areas found on the Casey Tract and to provide a map of those areas. It also identifies the
jurisdictional wetland delineation that was performed and subsequent consultations with the
USACOE and the North Carolina Division of Coastal Management (NCDCM).
Information sources used to prepare this section include: U.S. Geological Survey (USGS)
quadrangle map (Currituck); NCDOT aerial photographs of the project area (1:500); NCDOT
Photogrammetric Topography Maps (1:100); Soil Conservation Service (SCS) soil maps; United
States Fish and Wildlife Service (USFWS) National Wetlands Inventory Map (Currituck, NC);
and N.C. Natural Heritage Program's (NC-NHP) Classification of the Natural Communities of
North Carolina Third Approximation (Schafale and Weakley, 1990). Research using these
resources was conducted prior to the field investigation.
Wetlands and surface waters fall under the broad category of "Waters of the United
States" as defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean
Water Act (33 U.S.C. 1344) and are regulated by the USACOE. In addition, Currituck County is
one of the Coastal Counties under the jurisdiction of the Coastal Area Management Act (CAMA)
of 1974. The wetland delineation on the Casey Tract was conducted using the field delineation
methods of the 1987 Wetland Delineation Manual. The wetland evaluation was conducted
according to the NCDEM Guidance for Rating the Values of Wetlands in North Carolina, Fourth
Version.
Coastal wetlands are considered Areas of Environmental Concern according to the
Coastal Area Management Act of 1974 (Article 7: Part 3, 113A). These areas are influenced by
tidal activity and are delineated based on the presence of coastal marsh plant species as designated
by the North Carolina Division of Coastal Management (NCDCM). Resource delineated these
coastal wetlands separately from the non-coastal wetlands on the Casey Tract.
The field survey and wetland delineation was conducted by Resource biologists on June
' 28 and June 29, 1995. Plant communities and their associated wildlife were identified using a
variety of observation techniques, including active searching, visual observations with binoculars,
and identifying characteristic signs of wildlife (sounds, tracks, scats, and burrows). This
' information was obtained using field guides. (Burt, 1952; Conant & Collins, 1958; Ferrand, 1993;
Radford et al, 1968; and Webster et al, 1985). The delineated wetlands are shown on Figure 3.
' 2.2 Biotic Resources
Living systems described in the following sections include communities of associated
' plants and animals. These descriptions refer to the dominant flora and fauna in each community
and the relationship of these biotic components. Scientific nomenclature and common names

(when applicable) are used for the plant and animal species described. Subsequent references to
' the same species include the common name only. Vegetative communities as identified on the
National Wetland Inventory maps are shown on Figure 4.
' 2.2.1 Vegetative Communities
2.2.1.1 Mesic Mixed Hardwood Forest
' This upland community type is found throughout the Coastal Plain on north facing river
bluffs and ravine slopes, and less commonly on upland flats or islands surrounded by peatland or
' swamp communities. On the Casey Tract this community type is found around the edges of the
field. Elevations within this community are generally around 4 feet above msl. Soils are identified
as Altavista fine sandy loam. At the northeast corner of the field two unmaintained, shallow
' ditches extend through the forest to the edge of the marsh.
' Vegetation within this community is a mixture of upland and lowland species forming a
dense canopy, scattered understory, and a sparse shrub and herbaceous layer. The canopy is
dominated by large loblolly pines (Pinus taeda) and sweetgum (Liquidambar styraciflua). Many
' of these trees reach heights of 60 to 80 feet and diameters up to 24 inches diameter at breast
height (dbh). The understory is a mixture of red maple (Acer rubrum), sweetgum, black gum
(Nyssa sylvatica), American holly (Ilex opaca), and red mulberry (Morus rubra). The widely
scattered shrub layer is dominated by wax myrtle (Myrica cerifera) and blueberry (Vaccinium
sp.). The sparse herb layer contains poison ivy (Toxicodendron radicans), common greenbrier
(Smilax rotundifolia), and Virginia creeper (Parthenocissus quinquefolia). One area of large
pines near the northwestern corner of the field contains widely scattered pink lady's-slippers
(Cypripedium acaule).
' 2.2.1.2 Swamp Forest
This wetland community is found throughout the Coastal Plain along rivers and streams as
well as within very poorly drained flat areas with high water tables. The soils are generally wet to
saturated year round, strongly acidic with an organic layer overlying clay or sand. Within the
project area the Currituck County Soil Survey lists the soil type as Ponzer muck. On the Casey
Tract the swamp forest occurs on the lower elevations (1 foot or less) between the field and the
coastal marsh along the creeks. During the site reconnaissance, most of this community had
standing water several inches deep over very soft mucky soils. The swamp forest receives runoff
' and drainage from the adjacent fields as well as occasional tidal flooding from extremely high
wind tides in the creek.
' The swamp forest has distinctive layers of vegetation from canopy to emergent aquatic
vegetation. The canopy is dominated by swamp tupelo (Nyssa biflora), bald cypress (Taxodium
distichum), loblolly pine, black gum, and sweetgum. The understory consists of young black
' gum, sweetgum, red maple, water oak (Quercus nigra), red bay (Persea borbonia), and sweet
bay (Magnolia virginiana). The shrub layer is dominated by wax myrtle, highbush blueberry

(Vaccinium corymbosum), black titi (Cyrilla racemiflora), and coastal pepperbush (Clethra
' alnifolia). The herbaceous layer varies with the amount of sunlight reaching the forest floor and
the degree of inundation. In areas with low sunlight, royal fern (Osmunda regalis), southern lady
fern (Athyrium asplenioides), lizard tail (Saururus cernuus), and pennywort (Hydrocotyle
' bonariensis) are common. Areas receiving more sunlight are dominated by sawgrass (Cladium
jamaicense), blueflag iris (Iris versicolor), arrow-head (Saggitaria latifolia), water plantain
(Alisma subcordatum), and pondweed (Potamogeton sp.).
2.2.1.3 Tidal Freshwater Marsh
' This wetland community is typically found along the margins of drowned rivers and
creeks, and the estuaries of the northeastern Coastal Plain. Designated as coastal wetland by the
State Coastal Area Management Act, these marsh communities are influenced by the irregular
' wind tides of Currituck and Albemarle Sounds. They tend to occur on saturated mucky organic
soils with a dense root mat near the surface and very soft muck underneath. On the Casey Tract
' this community is found mostly along Buckskin Creek where the soils are mapped as Currituck
mucky peat or Conaby muck. The marsh is quite extensive along the eastern side of the property.
The marsh community is dominated by dense stands of sawgrass 4 to 5 feet tall with
t smaller scattered stands of cattails (Typha latifolia). There are also several stands of common
reed (Phragmites australis). Along the boundary with the swamp forest the marsh gives way to a
narrow shrub thicket of wax myrtle, black willow (Salix nigra), and swamp rose (Rosa palustris).
Bald cypress is scattered along the creek and the margins of some open water areas in the marsh.
Also occurring within the open water areas is arrowhead, pondweed, and some other aquatic
' emergents. Widely scattered hummocks within the marsh have wax myrtle, black willow,
sweetgum, tupelo, royal fern and blueflag iris.
2.2.1.4 Agricultural Field
A 4.9 acre field occupies the central portion of the Casey Tract. The field has one
drainage ditch (3 feet wide and 1-2 feet deep) flowing north from the old homesite into the forest.
Other shallow ditches (less than 12 inches deep) are located along the perimeter of the field and
connect to the above ditch or the ditches in the northeast corner of the field. The field was
' planted in soybeans at the time of the site visit.
' The United States Department of Agriculture Consolidated Farm Services Agency
(USDA-CFSA) (formerly ASCS) office has determined that the entire 4.9 acre field and 1.1 acres
of house, driveway, and timbered non-wetland does qualify for a prior converted wetland
determination. The soil within the field is identified as Altavista fine sandy loam by the Currituck
County Soil Survey. Altavista fine sandy loam is described as a moderately well drained soil on
smooth ridges near small streams. Seasonal wetness can be a limiting factor to some crops and
' other uses.

2.2.2 Faunal Components
' A variety of wildlife species were observed on the Casey Tract and many others would be
expected to utilize the site. The forest communities on the tract provide food, shelter and
t breeding areas for both game and non-game species. White tailed deer (Odocoileus virginianus)
signs were observed in every vegetative community. Deer use the field for feeding and the
forested areas for food and shelter. Raccoon (Procyon lotor) signs were also observed in all
habitats. They utilize the marsh and creek shore for feeding and the swamp forest for shelter and
foraging. The river otter (Lutra canadensis), mink (Mustela vison), and marsh rabbit (Sylvilagus
palustris) are also likely inhabitants of the marshes and swamp forest communities on the
' property.
Gray squirrels (Sciurus carolinensis) were observed in the forested areas, both swamp and
' upland. The gray fox (Urocyon cinereoargenteus) would be expected to traverse the Casey Tract
utilizing the woodland and field areas. The eastern cottontail rabbit (Sylvilagus floridanus) and a
' variety of mice and woodland rats can be found in and around the old field margins. Various bats
would also be expected to use the open field for feeding and the larger trees for shelter.
A variety of song birds were observed on the tract. The robin (Turdus migratorius),
' Northern cardinal (Cardinalis cardinalis), mourning dove (Zenaida macroura), and Eastern
mockingbird (Mimus polyglottus) were found in the old field and forest edges. Warblers typically
' utilize the swamp forest along with wood ducks (Aix sponsa) and the barred owl (Strix varia). A
ruby-throated hummingbird (Archilochus colubris) and a red-winged blackbird (Agelaius
phoeniceus) were observed in the coastal marsh. The great blue heron (Ardea herodias) and
' other wading birds would be expected in the marsh and creek areas. Several osprey (Pandion
haliaetus) were observed over the creeks. Woodpeckers such as the red-bellied (Centurus
carolinus), pileated (Dryocopus pileatus), and downy (Dendrocopos pubescens) would be
expected in the woodland habitats. A fish crow (Corvus ossifragus) was observed along the
forest edge. Many other birds would be expected to utilize the property.
' The Casey Tract provides suitable habitat for a wide variety of reptiles and amphibians.
Although only a brown water snake (Natrix taxispilota) was observed, many different snakes
including the copperhead (Agkistrodon contortix) and Eastern cottonmouth (Agkistrodon
piscivorus piscivorus) are likely to inhabit the woodland habitats and swamp areas respectively.
Several green anoles (Aeolis carolinensis carolinensis) were observed along the forest edge. The
' southern leopard frog (Rana utricularia) and bullfrog (Rana catesbeiana) were observed along
the drainage ditches near the swamp forest.
Cowells Creek and Buckskin Creek have been identified as high quality freshwater
fisheries by the N.C. Wildlife Resources Commission and are considered part of the inland
primary nursery area for Tull Creek. Largemouth bass (Micropterus salmoides), white perch
' (Moron americana), catfish (Ameiurus sp.), and various sunfishes (Lepomis sp.) are the common
sport fishes found in the creeks. Cowells Creek and Tull Creek have also been identified by the

North Carolina Division of Marine Fisheries as important spawning areas for the anadramous
species blueback herring (Alosa aestivalis) and alewife (Alosa pseudoharengus).
2.3 Wetland Delineation and Consultation
2.3.1 Wetland Delineation
Resource identified approximately 15.9 acres of the 24.3 acre site as being jurisdictional
wetlands including 11.9 acres of coastal marsh (as defined by the Coastal Areas Management
Act), 3.2 .acres of swamp forest and 0.8 acres of other wetlands. 4.9 acres have been designated
as PC by the USDA Consolidated Farm Service Agency (CFSA). The remainder of the site
includes 1.1 acres of driveway, house and timbered non-wetland and 2.4 acres of forested
uplands.
2.3.2 Consultation with the US Army Corps of Engineers and NC Division of Coastal
Management
On June 29, 1995 Resource met with Richard Watts of the NC Division of Coastal
Management to verify the coastal marsh delineation conducted on the Casey Tract. Mr. Watts
agreed with the delineation of the coastal marsh limits on the property. On August 15, 1995
Resource met with Mr. Mike Bell of the US Army Corps of Engineers, Wilmington District, to
confirm the wetland delineation on the Casey Tract. Mr. Bell concurred with the delineation as
performed by Resource.
Routine wetland determination forms required by the U. S. Army Corps of Engineers and
wetland rating worksheets as required by NCDEM are included in Appendices A and B,
respectively.

3.0 OTHER CONSIDERATIONS
' 3.1 Threatened and Endangered Species
' 3.1.1 Federally Protected Species
Some populations of plants and animals have been in decline or are in the process of
' decline either due to natural forces or due to their inability to coexist with man. Rare and
protected species listed for Currituck County, and any occurrence of these species are listed in
Table 1 and discussed below.
' Plants and animals with federal classification of Endangered (E), Threatened (T) ,
Proposed Endangered (PE) and Proposed Threatened (PT) are protected under provisions of
' Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. The United States
Fish and Wildlife Service (USFWS) lists the Kemp's ridley sea turtle (Lepidochelys kempii) and
the leatherback sea turtle (Dermochelys coriacea) as the only federally protected endangered
species reported in Currituck County as of the March 1995 listing. The green sea turtle
(Chelonia mydas) and the loggerhead turtle (Caretta caretta) are federally listed as threatened
species in this county. These species are typically found at sea and may also enter bays and
' sounds and may be found on beaches. This site lacks these types of habitat.
' According to USFWS, other federally protected threatened species listed for Currituck
County include the Dismal Swamp southeastern shrew (Sorex longirostris ftsheri), the piping
plover (Charadrius melodus) and the seabeach amaranth (Amaranthus pumilus). The Dismal
Swamp southeastern shrew is a small, long-tailed shrew found in the region of the Great Dismal
Swamp in Virginia and North Carolina. It tolerates a variety of habitats from fairly dry to moist
to wet areas. Specimens have been reported in grassy fields, clear-cut regenerating forests, young
' forests with shrubs, wax myrtle thickets, common reed flats, mature pine and deciduous forests.
No specimens have been reported in the vicinity of the Casey Tract. The piping plover is a small
(6-7.5") wading bird, typically found on sand beaches and tidal flats. This type of habitat is not
found on the proposed mitigation site. The seabeach amaranth is a monoecious annual herb with
fleshy, roundish leaves, large fiuits, and numerous branched stems. This reddish tinted amaranth
is found on the upper beach and lower foredune of coastal barrier islands. This type of habitat is
t not found on or near the Casey Tract.
Federal Candidate species are not legally protected under the Endangered Species Act and
are not subject to any of its provisions including Section 7, until they are formally proposed or
listed as Threatened or Endangered. Candidate 2 (C2) species are defined as taxa for which there
' is some evidence of vulnerability, but for which there is insufficient data to warrant a listing of E,
T, PE, or PT at this time. The black rail (Laterallus jamaicensis) and the Virginia least trillium
(Trillium pusillum var virginianum) are listed as C2 for Currituck County. The black rail is a
' small (5-6") bird found in tidal marshes, grassy marshes and stubble fields. None were observed
on the Casey Tract. The Virginia least trillium is a small, perennial herb with an erect stem, a
whorl of three leaves, and flowers with three petals. It is typically found in moist, rich soils of

' during the site visit to the Casey Tract.
3.1.2 National Marine Fisheries Service
' National Marine Fisheries Service (NMFS) has jurisdiction over aquatic Threatened and
Endangered species. The sea turtles listed above fall under this jurisdiction and NMFS has
' reported that none of the species indicated are found on or around the study area. The shortnose
sturgeon (Ascipenser brevirostrum) is the only endangered species indicated by NMFS that may
be likely to inhabit Tull Creek downstream of the Casey Tract.
' 3.1.3 North Carolina Natural Heritage Program (NC-NHP)
' The NC-NHP compiles lists of plants and animals which are protected under state law.
These lists typically include threatened and endangered species listed by the USFWS with
additional species that the NC-NHP deems important but that are not federally protected. State
' and federal designations and species occurrences sometimes differ and are addressed here. The
NC-NHP lists the Virginia least trillium (federally listed as C2) as an endangered species
' protected by the state. No specimens have been reported and none were observed during the site
visit. The NC-NHP also lists the occurrence of the federally listed red-cockaded woodpecker
(Picoides borealis) and the manatee (Trichechus manatus) in Currituck County. The red-
cockaded woodpecker is a small (8-9") wood boring bird found in open stands of mature pines.
The Casey Tract does not contain this type of habitat nor were any specimens observed during the
site visit. The manatee is a large, (7-13 feet, 1300 lbs) dark grey, migratory marine mammal
' found in brackish lagoons, mouths of rivers and shallow areas. The typical range of manatees is
from Beaufort, N.C. to Florida and the Gulf of Mexico; very few are reported north of Cape
Hatteras, N.C. No manatees have been reported in the vicinity of the Casey Tract.
' The NC-NHP lists the Carolina grasswort (Lilaeopsis carolinensis) as a threatened
species protected by the state. The Carolina grasswort is a perennial rhizomatous herb with
' elongate leaves (7-35 cm). They are found in brackish and freshwater marshes, along pond
margins, sluggish streams, and ditches. Carolina grassworts have not been reported on or near
the Casey Tract.
' In addition to plant and animal elements, the NC-NHP also classifies natural communities.
Although these areas are not legally protected, the state recognizes the importance of preserving
' these areas. These communities are manually labelled on a topographic map at the NC-NHP
office, thus precise locations of these communities is difficult to ascertain. Tull Creek, located
' downstream from the study site, is described as an estuarine, tributary stream with tidal marshes
and swamps and patches of higher, nontidal wetland.

3.2 Cultural Resources
' Resource personnel reviewed existing literature relative to the presence of cultural
resources on or adjacent to the Casey Tract property. According to information obtained from
the North Carolina Department of Cultural Resources, one cultural resource site is known to
' occur on the Casey Tract mitigation site property. No cultural resource sites have been identified
on adjacent properties. A brief description of the site is discussed below, and is taken from an
' archaeology study report, prepared by NCDOT in December 1993 as part of the NC 168
widening project.
31- K-80 This site is an abandoned farmstead containing deteriorated remains of a mid-
' to late 19th to recent 20th century dwelling, a barn, and several other outbuildings located
along the north side of NC 168 approximately 200 meters east of Sligo. An intensive site
' walkover with selective non-screened shovel pits and at least 15 screened shovel pits were
excavated with no recovery of artifacts. Items recovered during a surface walkover of on-
site agricultural fields included a 1 pearlware ceramic sherd, 4 whiteware ceramic sherds,
and 1 porcelain ceramic sherd. The components of the farmstead are ascertainable,
although the site is heavily grown over. It is expected that modern use of this area has
obscured or disturbed most archaeological remains that might have been left from the
' early years of the site's occupation (Robinson, 1993)
3.3 Hazardous/Toxic Materials Sites
' During the initial site investigation on June 28-29, 1995, Resource personnel did not
observe any evidence on or immediately adjacent to the Casey Tract which would indicate the
' potential presence of hazardous/toxic materials or sites.
' Practically reviewable public environmental records were researched in order to
evaluate environmental conditions within appropriate search distances of the subject property.
Environmental records reviewed were the most recent records available to Resource by the
' respective regulatory authority.
3.3.1 National Priority List
' Sites that receive the highest ranking under the Superfund hazard ranking system are
placed on the National Priority List (NPL) and thus become eligible to have cleanup activities
' financed by Superfund. The NPL of Superfund Sites for North Carolina was evaluated at an
approximate search distance of one mile. According to United States Environmental
Protection Agency (USEPA) documents, no NPL facilities were located on the subject
' property or on properties within one mile of the subject property.

' 4.0 SURFACE HYDROLOGY/WATER BUDGET
' 4.1 Methodology
Information sources used to prepare this section of the report include: U. S. Geological
' Survey (USGS) 7.5 minute quadrangle map (Currituck); NCDOT aerial photographs of the
project area (1:500); NCDOT Photogrammetric Topography Maps (1:100); Soil Conservation
Service (SCS) soil maps; and National Oceanic and Atmospheric Administration
' (NOAA)/National Weather Service (NWS) precipitation data. Research using these resources
was conducted prior to the field investigation.
' Observation well installation, field permeability tests and measuring of water levels were
conducted by Resource geologists on June 28 and June 29, 1995. Additional water level
' measurements were made on August 31 and September 28, 1995. Description of these activities
are provided in the following sections of this report.
' 4.2 Geology and Soils
Lying approximately 25 miles east of the Suffolk Scarp and bordering the Atlantic Ocean,
' the geology of Currituck County is described as Quaternary surficial deposits of undivided sand,
clay, gravel, and peat deposited in marine, fluvial, eolian, and lacustrine environments (USDA,
SCS, 1982).
' The SCS general soil map identifies the project area as being within the Currituck soil
series along the Tull Creek drainage basin. The Currituck series is described as nearly level, very
t poorly drained soils that have a mucky surface layer and sandy underlying material. The detailed
soil map units on the Casey Tract include Currituck mucky peat, Conaby muck, Ponzer muck, and
' Altavista fine sandy loam. Currituck, Conaby, and Ponzer muck are included on both national and
local hydric soils lists. The soil map units are included on Figure 5.
' Currituck mucky peat is found along the margins of Buckskin Creek and Cowells Creek.
It is a nearly level, very poorly drained soil on broad flat marshes along Currituck Sound and its
tributaries. The surface layer contains highly decomposed organic matter. Permeability is
' moderate to moderately rapid. The seasonal high water table is at or near the surface. The soil is
flooded frequently by changing tides for very long periods.
' Conaby muck is present as an inclusion within the Currituck muck in the southeast corner
of the property and occurs in areas that are very poorly drained on low-lying broad flats and in
slightly depressed drainage ways. Permeability is moderate to moderately slow in organic layers
' and moderately rapid in the mineral layers. The seasonal high water table is at or near the surface.

Ponzer muck forms a band between the Currituck muck and the Altavista fine sandy loam.
Ponzer muck is another nearly level very poorly drained soil. The surface layer contains highly
decomposed organic matter. Permeability is slow in undrained areas. The seasonal high water
table is at or near the surface. If drained, this soil is well suited to crops with wetness being its
main limitation.
The farm field contains Altavista fine sandy loam (0-2% slope). This soil is moderately
well drained on smooth ridges near small streams and rivers. Permeability is moderate. The high
water table fluctuates between depths of about 1.5 to 2.5 feet below the ground surface in late
winter and early spring.
4.3 Soil and Groundwater Investigation
4.3.1 Observation Well Installation
Four observation wells were installed at the Casey Tract. The locations of these wells as
determined by field survey are shown on Figure 6. During each soil boring, samples were
collected on a continuous basis from the ground surface to approximately 6 to 7.5 feet below
ground surface. Samples were visually classified by a Resource geologist. Boring logs and well
construction diagrams are provided in Appendix D. Each boring encountered an organic-rich
orange-to-brown and light gray silty fine sand up to two feet thick at the surface, followed by a
gray mottled orange silty clay from 1.5 to 3 feet thick, and finally a light gray to brown silty sand
from 1.0 to 4.0 feet thick. CW-4 had the thinnest sand (1.0 foot) and a gray mottled orange fine
sandy clay developed at the base of the boring. The soils encountered in the borings suggest
fluvial to marine depositional environments.
Each soil boring was completed as an observation well so that shallow groundwater level
readings could be measured. Each well was constructed in general accordance with procedures
outlined in "Installing Monitoring Wells/Piezometers in Wetlands" (USACOE, 1993), a guidance
document issued by the Waterways Experiment Station of the U. S. Army Corps of Engineers.
The wells were constructed using 2 inch PVC with a factory slotted 0.010 inch screen from total
depth to within 0.5 to 1.5 feet of the ground surface (Appendix D). Each well has at least a 1
foot riser with a PVC cap. The annulus was filled with a uniformly graded No. 2 Morie silica
sand around the screen (and up to 1 foot above the screen) with a bentonite seal to the surface.
Soil and bentonite were mounded around the PVC at the ground surface o reduce the potential of
surface water impacts.
• Different procedures can be used to seal the annulus to prevent water flow from the
surface to the aquifer which could lead to abnormally high measured water levels. A concern for
using bentonite exclusively is that bentonite may shrink and crack during dry periods. Cement
grout seals may be installed to cover such potential cracks; however, cement grout can also crack
due to shrinkage while drying or due to freezing and thawing of the cement and/or the ground
surface (frost heave). Unlike bentonite, which will re-hydrate and expand during wet periods,
cement grout cracks would not close with wetting. Should water successfully reach the aquifer
Casey Tract
Mitigation Plan
caseymit.m05 13

prior to re-hydration and expansion of the bentonite, aquifer water levels would be expected to
equilibrate rapidly. ?? ?? -t'/Y?a?J
4.3.2 Field Permeability Tests
4
A 12 to 32 inch deep, 6 inch diameter boring was advanced within 5 feet of each
observation well, in addition to one boring advanced between CW-1 and CW-3. Two inches of
No. 2 Morie sand were placed in the bottom of each boring, then each borehole was pre-saturated
prior to conducting the infiltration tests. A known amount of water was added and the decrease
in water level was monitored at regular intervals.
At the time of the testing, groundwater levels in the observation wells were within 3 to 35
inches of ground surface. As a result of the shallow water table, results could not be obtained
from all of the infiltration tests. The results of the infiltration tests are presented in Appendix E.
Field determined infiltration rates at the Casey Tract ranged from 1.2 x 10-2 to 6.7 x 10'3 in/min
(5.1 x 10-4to 2.8 x 10'4 cm/sec).
4.3.3 Geotechnical Tests
Disturbed and partly disturbed soil samples (Shelby tube cores) were collected from
observation well CW-1 at a depth of 0 to 24 inches (STC-1) and 24 to 48 inches (STC-2) below
ground surface. At the time of Shelby tube collection it was noted that STC-2 had some loss of
material along the side of the tube for the entire length of the tube. The Shelby tube samples were
analyzed for Atterberg Limits, grain size distribution, and vertical permeability. Three attempts
were made to obtain an undisturbed sample from observation well CW-3; however, the soils were
too wet to remain in the Shelby tube.
The results of the geotechnical testing are included in Appendix F. A vertical permeability
test was conducted on the sample collected from 0 to 24 inches only. The loss of sample along
the sides of the 24 to 48 inch sample precluded the analysis of vertical permeability. A vertical
' permeability of 1.8 x 10'5 cm/sec was determined for the 0-24 inch sample. Classification testing
indicates that the soils sampled in the Shelby tubes are sandy loam clay with clay and silt size
particles making up 58% and 70% of the soil collected from the Casey Tract.
' 4.3.4 Water Levels and Groundwater Flow
' Due to the low barometric efficiency of shallow, unconfined and unconsolidated aquifers,
very minor water level changes are expected in response to barometric pressure variations.
Because each observation well has a sand pack in the annulus to within one foot of the surface
' and well screens are within 2.5 feet of the surface, the impacts on measured water levels due to
this and other natural loading effects (such as tidal fluctuations) are further minimized.
t Water levels were measured in each observation well on June 28, June 29, August 31, and
September 28, 1995. The water level data and groundwater elevations are included in Table 2.
' Casey Tract

Water levels in each well varied between measuring events. Variations in groundwater levels and
flow directions are likely to occur in response to precipitation events and water level fluctuations
in the ditches. In addition, other factors such as evapotranspiration, could cause groundwater
level fluctuations.
A groundwater contour map is provided as Figure 6. In general, groundwater flow is
toward the north with components of flow toward each creek. The groundwater level in the
agricultural fields is thought to be relatively low due to existing drainage ditches. Note that
groundwater elevations only range over about 1.0 foot across the site, and the contour interval for
the map is 0.5 foot. Groundwater levels measured at the site ranged from 0.1 foot to 3.0 feet
below ground surface on September 28, 1995 (Table 2).
4.4 Water Budget Calculations
4.4.1 Introduction
in order to ascertain the quantity of water available for the mitigation site system, a water
budget analysis was performed. Evaluations of water inputs to, and outputs from, the system are
necessary for this calculation. Inputs to the system include tidal influx from the creeks,
precipitation, surface runoff from adjoining tracts onto the property, and groundwater inflow.
Outputs from the system include evapotranspiration, surface runoff off the property, infiltration,
and groundwater outflow. For the purpose of a water budget analysis without seasonal
groundwater level variations, current groundwater inflows and outflows are treated as being equal
and equivalent to a steady state condition. The difference between other inflows and outflows is
the change in surface and near-surface water storage which is available at the site to maintain a
coastal marsh system. Water quantities are presented in inches distributed over a given area.
4.4.2 Precipitation
Precipitation data collected since 1967 from the Elizabeth City NOAA/NWS weather
station, located approximately 15 miles southwest of the site, were evaluated to determine the
average rainfall input to the system. These data, along with generated monthly and annual data
plots, are included in Appendix G. The plot of monthly precipitation for 1993 and 1994 illustrates
great variability, but total precipitation is generally least in the fourth quarter for both years.
Approximately 70 to 80 percent of the annual precipitation falls during the growing season of
March through November. The plot of the annual precipitation data indicates that, since 1967,
the minimum annual rainfall was 36.11 inches which occurred in 1976, and the maximum was
72.52 inches which occurred in 1979. The 28-year average is 47.93 inches per year.
' 4.4.3 Creeks
Cowells Creek and Buckskin Creek adjoin the property on the western, northern, and
' eastern sides of the property. These creeks do not currently provide water to the proposed
mitigation area, but are important sources of water to the coastal marshes which currently exist on
' Casey Tract
Mitigation Plan
' caseymit.m05 15
April 2, 1996

the property. As a result of the proposed excavation in the mitigation plan, these creeks would
' also provide a hydrologic connection to the adjacent tidal creeks to saturate and sustain the
created coastal marsh in the mitigation area.
' 4.4.4 Surface Runoff
Regional topography, as defined by the USGS 7.5 minute series Currituck, North Carolina
' quadrangle (1982), suggests natural surface water drainage flows from the higher elevations south
of the property toward Cowells and Buckskin Creeks to the northeast and northwest. The south
side of the property, however, is bounded by drainage ditches and an elevated road which would
' intercept any potential overland flow from the south. The south side of the property is a surface
water drainage divide, with potential runoff from the property toward Cowells and Buckskin
Creeks which form the western, northern and eastern property lines, respectively. It is unlikely
' that any influx of water from runoff from adjoining upland properties could be expected.
4.4.5 Evapotranspiration Losses
' Water in the coastal marsh area will be lost through both evaporation and transpiration by
plants, referred to collectively as evapotranspiration. The technique used to estimate these
' combined evapotranspiration losses was the Blaney-Criddle Method (Blaney and Criddle, 1950).
In using this method, total conversion of the mitigation area to coastal marsh was assumed.
Calculations for the rate of evapotranspiration at the site are presented in Appendix H. The
assumed growing season is March through November. By calculating the monthly consumptive
use factors as a function of mean monthly temperatures recorded at the Elizabeth City, North
t Carolina weather station in 1994, and using a crop coefficient of 0.75 (appropriate for grasses and
small grains), a total annual evapotranspiration quantity of 40.46 inches was computed.
' 4.4.6 Surface Runoff Losses
The SCS TR-55 Hydrology Method (USDA, 1986) was used to illustrate the potential
runoff from the site prior to conversion to coastal marsh. The soil types within the site drainage
area were delineated based upon field investigations and soil surveys for Currituck County, North
Carolina conducted by the SCS. The total area for each soil type was calculated within the
' proposed mitigation area and the corresponding hydrologic group and curve number (CN)
assigned to each soil type. From the total areas of each soil type in the non-wetland and non-
coastal marsh areas and the corresponding CN, a composite CN for the entire mitigation area was
' calculated to be 74. A listing of the soil types identified, the corresponding CNs, total area of
each soil type, and the composite CN calculation are included in Appendix I. The identified soils
within the site drainage area are delineated on Figure 5. Each of the soil types identified at the
' site are of the hydrologic soil types 'C' and 'D', indicative of high runoff potential (hydrologic soil
groups are classified by the SCS as W, 'B', 'C', or'D' depending on infiltration capacity and runoff
' potential, with group 'A' soils having greatest infiltration capacity and lowest runoff potential, and
group 'D' soils having least infiltration capacity and greatest runoff potential). The 'C' and 'D'
' Casey Tract
Mitigation Plan
' caseymit.m05 16

I

classifications for the site soils are likely due to both low soil permeability and the high water
table.
The minimum precipitation event required to generate runoff from the site was calculated
to be 0.70 inches (calculations in Appendix I). Since the total precipitation in 1994 came very
close to the 28-year average, all 24-hour precipitation events exceeding 0.70 inches during that
year were tabulated and are also included in Appendix I. There were seven events with 0.70 to
0.99 inches, 10 events with 1.00 to 1.49 inches, four events with 1.50 to 1.99 inches, and two
events which exceeded 2.00 inches. From these data, total potential runoff from the property was
estimated to be 3.39 inches (calculations in Appendix I). By lowering the elevation of the
mitigation site to nearly groundwater level as part of the coastal marsh mitigation, surface water
runoff from the site will be greatly increased, and will approach 100% with increasing soil
saturation.
4.4.7 Infiltration Losses
t Infiltration rates of the soils within the proposed wetland area must be determined in order
to calculate the volume of water that will potentially drain through the soil in the mitigation area.
A series of field permeability tests were performed to determine the infiltration rates for the
' proposed site in its existing condition. Boreholes depths ranged from 12 to 32 inches. Also,
Shelby tubes were used to collect soil samples for vertical permeability and grain size distribution
' analysis. The locations of the field permeability tests are delineated on Figure 6. Refer to
Appendix E for the results of the permeability tests and Appendix F for the laboratory soil
analysis.

The observed infiltration rates during field testing were moderately slow (Appendix E).
Field determined infiltration rates at the Casey Tract ranged from 5.1 x 10' to 2.8 x 10' cm/sec
(1.2 x 10'2 to 6.7 x 10'3 in/min). The results of the laboratory vertical permeability test was 1.8 x
10'5 cm/sec. It appears likely that the field tests were at least in part a measurement of horizontal
permeability, which is typically much greater than vertical permeability. Designated hydrologic
soil groups for the corresponding soil types at the site correlate with laboratory measured
permeabilities, and indicate that the vertical permeability is low. The actual rate and quantity of
infiltration is dependent upon such factors as infiltration capacity of the soil, moisture conditions,
and water head at the surface. While permeability data alone indicates that infiltration losses will
be relatively minor, the anticipated rise in groundwater level with site mitigation would render
these losses negligible, and therefore, were not included in the water budget calculation.
Furthermore, after mitigation, the site will be dominated by surface water hydrology.
4.4.8 Groundwater Outflow
Cowells Creek and Buckskin Creek serve as natural groundwater discharge areas at the
western, northern, and eastern edges of the property. Groundwater outflow also occurs in the
agricultural ditches at the site which are designed to dewater the shallow unconfined aquifer. Flow
could also occur toward the major ditch along the road at the southern edge of the property.

After excavation occurs as part of the proposed mitigation, groundwater outflow would only be
crucial in those areas that are currently designated as wetland. In order to minimize potential
impact to those areas, the existing buffer zone is proposed to be maintained between the
mitigation area and the currently established wetland areas. The buffer zone varies from a
minimum of 50 feet to 250 feet in width.
4.4.9 Available Water
The proposed mitigation area has been certified to be prior converted wetland by the SCS.
Coastal marsh areas and wetland have been identified immediately adjacent to the proposed
mitigation site. Table 3 summarizes the water budget for both pre-mitigation and post-mitigation
conditions. Insufficient water is currently available to the mitigation site for coastal marsh
hydrology. This is due to ground elevations which cause infiltration and surface runoff losses.
The mitigation plan proposes to convert the farm field area to functional coastal marsh. This will
be accomplished by excavation of the field area to an elevation approximating the current
elevation of the nearby coastal marsh on the property. The major ditches at the southern edge of
the property, hydraulically connected to Cowells Creek and Buckskin Creek, will be extended into
the excavated area.
After the mitigation plan is implemented, the total available water for the proposed
mitigation area is equal to precipitation and influx of water from the creeks less losses from
evapotranspiration and surface runoff. Precipitation will provide approximately 47.9 inches of
water per year over the mitigation area based on a 28-year average of annual precipitation data.
Approximately 40.5 inches of water will be lost per year due to evapotranspiration over the
mitigation site. After mitigation implementation, more losses occur with increased soil saturation
and runoff, but this would be offset by the continual availability of water from the adjoining creeks
to maintain coastal marsh conditions.
' 4.5 Summary of the Water Budget Findings
' Based on this study, the following conclusions are provided:
1. The proposed mitigation area has been classified as a prior converted wetland by the
' CFSA; wetland conditions do not currently exist in this area due to agricultural practices.
2. Insufficient water is currently available to the mitigation site for coastal marsh hydrology
' due to ground elevations which allow infiltration and surface runoff losses and lack of tidal
influx on the site.
' 3. To significantly reduce infiltration losses and to allow hydrologic connection to the tidal
marsh system, the proposed mitigation plan involves excavation of the mitigation area to
elevations which approximate those of the adjoining coastal marsh area.

4. Excavation for mitigation purposes could adversely impact the existing wetland by
increasing groundwater outflow from those areas. A variable width forested buffer zone is
proposed between the existing wetland and the proposed coastal marsh creation area to
reduce the potential groundwater outflow from the existing wetland.
5. Existing ditches on the southern side of the property will be extended to connect the
converted area to Cowells Creek and Buckskin Creek. After mitigation, tidal influx of the
adjoining creeks and precipitation will provide water to sustain the coastal marsh system.
Losses from evapotranspiration and increased surface water runoff will be offset by
maintaining continual influx of water by establishing hydrologic connection with the
creeks.

5.0 MITIGATION PLAN Q
5.1 Introduction
' NCDOT is proposing to mitigate approximately . acres of coastal marsh wetland
impacts associated with the widening of NC 168, Project R-2228, in Currituck County on the
Casey Tract. The property is ideally suited for the creation of a tidal freshwater marsh mitigation
' site due to the existence of adjacent coastal marsh to the north, east and west sides of the site.
5.2 Existing Conditions
' According to the recent survey performed by Resource (Figure 2 and Appendix K) the
Casey Tract is approximately 24.3 acres and consists of 11.9 acres of existing tidal freshwater
' marsh, 3.98 acres of other jurisdictional wetland, and 6.0 acres of prior converted (PC) wetland
which includes an existing entrance road, house and agricultural field. The remainder of the site
consists of 2.42 acres of forested upland areas between the jurisdictional wetland and the PC
' fields.
The Casey Tract is situated along Buckskin and Cowells Creeks and the coastal marsh on
the property extends to the confluence of the creeks. Both creeks are tributaries of Tull Creek
which flows into Tull Bay at the northern end of Currituck Sound. Buckskin and Cowells Creek
' are typical blackwater coastal streams with occasional tidal influence from the wind driven tides in
Currituck Sound. The streamwater is acidic, low in mineral sediment and colored by tannins.
Both creeks are characterized by meandering channels approximately 150 feet wide with a number
of smaller tributaries, and the creek banks are lined by coastal marsh and cypress trees.
The tract is essentially flat with the natural topography on the tract ranging from
approximately 0.5 feet above mean sea level (msl) at the coastal marsh edge to 4 feet above msl at
the center of the PC field. An old homesite with a barn and trees occupies the central portion of
the property and is surrounded by the farm field. Approximately 4.9 acres of the site has
' experienced agricultural activities, including approximately 300 linear feet of man-made ditches.
There is an existing drainage ditch in the middle of the northern side of the PC field area. The
ditch has contributed to the lowering of the water table in the PC field area and the loss of
' wetland hydrology for the PC field. Canals adjacent to NC 168 connect the PC fields to both
creek channels. Existing site conditions are illustrated in Figure 2.
5.3 Reference Ecosystem
The Reference Ecosystem for the proposed Casey Tract mitigation site is the existing tidal
t freshwater marsh occurring on-site along Buckskin Creek in the northern and eastern portions of
the property (Figure 7). Topographic survey data for the Reference Ecosystem, collected in the
field by Resource in July 1995, indicates that elevations in this area range from approximately 0.9-
2.4 feet above mean sea level (Figure 5, Sheet 1).

According to the Soil Survey for Currituck County (USDA-SCS, 1982), soils in the
Reference Ecosystem are Currituck mucky peat and Conaby muck. Currituck mucky peat is
found along the margins of Buckskin Creek and Cowells Creek. It is a nearly level, very poorly
drained soil on broad flat marshes along Currituck Sound and its tributaries. The surface layer
contains highly decomposed organic matter (ranging from 20-60%) approximately 28 inches thick
over an underlying loamy sand or sand to depths of approximately 60 inches. Permeability is
moderate to moderately rapid; the seasonal high water table is at or near the surface; and the soil
is flooded frequently by changing tides for very long periods. Conaby muck is present as an
inclusion within the Currituck muck in the southeast comer of the property, and occurs in areas
that are very poorly drained on low-lying broad flats and in slightly depressed drainageways. The
surface layer contains highly decomposed organic matter (ranging from 20-60%) approximately
13 inches thick over an underlying stratified sand or sandy loam to depths of approximately 73
inches. Permeability is moderate to moderately slow in organic layers and moderately rapid in the
mineral layers. The seasonal high water table is at or near the surface. Both Currituck mucky
peat and Conaby muck are listed on the local hydric soils list (June 1991) and the national hydric
soils list (June 1991).
Resource reviewed this tidal freshwater marsh on June 28-29, 1995 as part of a natural
communities assessment. The Reference Ecosystem comprises 11.9 acres of the 24.3 acre Casey
Tract parcel. The marsh community is dominated by dense stands of sawgrass 4-5 feet tall with
smaller scattered stands of cattails. There are also several stands of common reed. Along the
boundary with the adjacent swamp forest, the marsh gives way. to a narrow shrub thicket of wax
myrtle, black willow, and swamp rose. Bald cypress is scattered along the creek and the margins
of some open water areas in the marsh. Also occurring within the open water areas is arrowhead,
pondweed, and some other aquatic emergents. Widely scattered hummocks within the marsh
have wax myrtle, black willow, sweetgum, tupelo, royal fern, and blueflag iris.
The Reference Ecosystem exhibited hydrology patterns typically associated with other
tidal freshwater marshes. Small open water canals, colloquially called "guts", meander through
the marsh with many isolated pockets of standing water, organic soils saturated to the surface,
and areas of higher elevation (hummocks). Occasional tidal influence in Cowells Creek and
Buckskin Creek result from wind-driven influxes of water from Tull Bay and Currituck Sound.
One observation well (CW-2) was installed in the ecotone area between the tidal freshwater marsh
and the forested wetland on the site. According to water elevation data collected by Resource
personnel on June 28, 1995 for this observation well, the depth to water below existing ground
surface (1.3 feet above mean sea level) was 0.2 feet.
An additional Reference Ecosystem has been established at the Ballance Farm mitigation
site located on Poyner Road approximately 2.1 miles north of Sligo. This site may also serve as
an important reference for the Casey Tract as it contains approximately 50 acres of tidal
freshwater marsh (coastal marsh) along Tull Creek (Figure 7a). This coastal marsh has an
elevational range of 0.4 to 2.0 feet above mean sea level. Soils in the Ballance Farm coastal
marsh are Currituck mucky peat and vegetation is dominated by sawgrass with smaller stands of
black needlerush (Juncus roemerianus), leafy sedge (Scirpus robustus), common reed, and

i
cattails. Hydrology in the Ballance Farm coastal marsh is similar to that described at the Casey
Tract coastal marsh. Two observation wells (BW-21 and BW-22) were installed in the Ballance
Farm coastal marsh. Resource personnel collected water elevation data from these wells after
their installation in December 1995, and measured water levels were at or slightly above ground
surface.
5.4 Hydrological Modifications
' Hydrological modifications for the coastal marsh areas will involve the construction of a
channel network connected to Buckskin and Cowells Creeks and the lowering of the site
elevations in the created coastal marsh areas to the elevations of the coastal marsh Reference
Ecosystem areas. Adequate water should be available from the adjacent creeks, groundwater, and
rainfall to sustain the necessary hydrology for coastal marsh wetland areas. Monitoring of the
' groundwater levels within each zone of the created coastal marsh areas will confirm the
establishment of the necessary hydrology. Refer to Figure 13 for the proposed monitoring plan.
' 5.5 Proposed Site Grading
The Water Budget analysis for the site has determined that the site is capable of sustaining
' coastal marsh wetland if the losses due to infiltration are eliminated by excavaton and hydrologic
connection established between the site and the adjoining creeks. The groundwater in the area of
the PC fields is within 3 feet of the ground surface. The proposed mitigation plan will involve
' lowering the site in the PC field area in order to establish wetland hydrology and constructing
coastal marsh wetland as shown on the Mitigation Plan, included as Figures 8 through 12. As the
' mitigation plan proposes excavation of material from the site, the evaluation of plow pans and
field crowns was not performed since they would be eliminated during excavation activities. The
existing forested uplands between the PC field area and the existing wetland will be left in their
' existing condition as a buffer in order to reduce impacts to groundwater levels within the existing
wetland areas. The existing road side drainage ditches will be modified as necessary and extended
into the PC field areas to establish tidal influences within the constructed coastal marsh wetland in
' the PC field areas. The ditches will allow for tidal flushing of the constructed coastal marsh by
forming a hydrologic connection between the bordering tidal creeks and the site. The mitigation
site consists of 5.5 acres of the 6 acres of the PC area; a portion of the existing road and of the
' forested upland in the middle of the PC fields will be left as uplands to serve as construction
staging areas and to allow access to the site for monitoring and maintenance.
' The proposed grading will involve constructing ditches which will form hydrologic
connections between the existing roadside ditches and the ditch in the northern end of the site.
The ditch will be a four foot trapezoidal ditch with a bottom elevation of approximately -0.3 feet
msl, with side slopes graded approximately 5% slopes to an approximate elevation of 0.4 feet
above msl. The large trapezoidal ditch will ensure adequate flow of water into and out of the site
' during periods of tidal influences. The areas from the top of the ditch slope to the areas adjacent
to the variable width forested buffer strip will have an approximate 1.0% grade towards the ditch.

areas, within the existing tidal freshwater marshis at about elevation 2.0 above mCSL The lowest
' areas are at about elevation 0.4 above msl. All excavated soil materials will be hauled off-site for
disposal in an appropriate upland site.
' Implementation plans will include the required elevation tolerance and other requirements
for final site preparation such as preparation of an as-built survey additional soil testing to
' determine nutrient requirements, compaction criteria, final site preparation, sequencing of
construction, erosion and sedimentation control measures and further evaluations of the soil
stratum or site necessary to ensure a successful coastal marsh mitigation site.
' 5.6 Soils
' Fertility and other sampling of exposed soils to be planted and soils in the on-site
Reference Ecosystem will be included in the implementation plan. The majority of the mitigation
area is dominated by Altavista fine sandy loam (See Section 4.2 - Geology and Soils), according
' to the Soil Survey. Following excavation, the exposed soil will consist of a fine sandy loam to a
sandy clay loam. This soil is not included on the hydric soils fist, and the fertility of the soil in the
mitigation area is not initially expected to be identical to that of the Reference Ecosystem.
' However, once the plants become established, they will begin trapping sediment and producing
detritus, thus increasing the organic component of the soil. According to A,,,' me, et:al: (1982),
Coastal marsh specie$„p?,n;.become successfully established on sandyloam substrate. _Thus,.it will
' not be necessary to spread hydric soils stockpiled from impacted sites.
Appropriate erosion and sediment control devices will be installed prior to grading
' activities and maintained during the construction phase of the project to reduce erosion of hydric
soils from the site. Erosion and sediment control device(s) will remain in place until the
' mitigation site has stabilized.
5.7 Vegetation
eCtion of vegetation for this site was, based,. in part, on the Reference Ecosystem; which
ipoudes sawgrass and lizard tail. Cattails and giant reed are also present in the Reference
Ecosystem however they will not be planted as they are aggressivweedy sp?Ctes .like y to
-vegetate naturally. Species found in impacted marshes associated with this project were also
incorporated in the mitigation site. Some of the impacted species include cattails, giant cordgrass
' (Spartina cynosuroides), soft rush, sedges, wild cotton (Hibiscus spp.), and woolgrass (Scirpus
cyperinus). All vegetation proposed is dependent upon availability of acceptable, high quality
species; NCDOT will attempt to obtain plant material from local sources to the practical extent
' possible. Seeding in non-submerged areas will be done, by the NCDOT at the time of
implementation with a wetland seed mixture.
' Casey Tract
Mitigation Plan
' caseymit.m05 23

It is proposed that some of the vegetation, especially sawgrass, needed for the project be
' transplanted from the adjacent coastal marsh (Reference Ecosystem). This species spreads rapidly
and areas in the Reference Ecosystem impacted by removal of plants are likely to revegetate
quickly. Transplanting will be supervised by appropriate personnel to assure that impacts to the
' habitat are minimal.
All vegetation proposed is dependent upon availability of acceptable, high quality species.
For species other than transplants, the NCDOT will attempt to obtain plant material from local
sources to the practical extent possible. Seeding in non-submerged areas may be done with a
commercially available wetland seed mixture. Refer to Figure 13 for a layout of the proposed
' vegetation.
Determination of vegetation placement for planting was based on locations of similar
' species in other marshes as well as species' tolerance to tidal flooding, habitat, wildlife value and
diversity (Hammer, 1992). Depending upon species availability, planting will be done in zones
based on the elevational gradient (Figure 13). In areas of the highest elevation (zone 1) species
' planted may include woolgrass, rosemallow (Hibiscus moscheutos), lizard tail, soft rush and
sedges. At a slightly lower elevation (zone 2), sawgrass and common three-square (Scirpus
americanus) edges may be planted. Tall cordgrass will be planted at the lowest elevations in
' zone 3 along ditch banks.
' All vegetation will be planted in a random fashion with two foot spacing. Some natural
re-vegetation may occur, however, plant spacing and the plants ability to out compete other
species should help to preclude the invasion of unwanted species. If necessary, a fertilizer such
' as slow-release Osmocote will be applied to aid in the establishment of the plants.
Final planting scheme, planting methodology and timing, exact plant species, plant source,
' details on fertility testing and use of fertilizer will be included in the implementation plan to be
prepared by the NCDOT.
' 5.8 Monitoring Plan
Prior to planting, the mitigation site will be inspected by the NCDOT for proper elevation,
' grade, and suitability of soils. Availability of acceptable, high quality plant species will be
determined. During the planting time, proper planting methods will be monitored including
' spacing and species composition.
After planting is complete, an as-built report will be submitted to the USACOE and/or
other permitting agency within 90 days of mitigation site completion. This report should include
' information such as final elevations, photographs, sample plot locations and well locations.

' Success of the mitigation program is dependent in part on establishment of appropriate
hydrology referenced to the target coastal marsh ecosystem occurring at the depths concluded in
the water budget analysis. Reference Ecosystem wells, located off-site, and new proposed
' observation wells (constructed in accordance with USACOE guidelines) as indicated on Figure 9,
will be monitored on a schedule which will be sufficient to document water levels and water level
' fluctuations in response to tides. There will be continuous monitoring at an appropriate frequency
in selected wells or gauges.
' The project will be considered successful if the planted species have a survival rate of 50%
and provide an aerial coverage of at least 75% at the end of three years. It is expected that
successful long term establishment will occur after three years. At least 50% of specie prese in
' the mitigation site will be facultative wet (FACW) or obligate (OBL). If survival of species is
unsuccessful during the monitoring time, NCDOT will consult with the Division of Coastal
Management and recourse actions will be determined. NCDOT has developed a conceptual
' monitoring-plan to ensure the success of this proposed mitigation effort. The guidelines for this
effort are fisted below:

6.0 CONCLUSIONS AND RECOMMENDATIONS

1

11

I
I
Based upon the information developed in this study the following conclusions are
presented:
The 24.3 acre Casey Tract consists of 11.9 acres of freshwater coastal marsh, 3.98 acres
of jurisdictional wetland, 4.9 acres of prior converted (PC) wetland, 1.1 acre of driveway,
house and timbered non-wetland, and 2.42 acres of forested upland.
2. The proposed mitigation area has been classified as a prior converted wetland by the
CFSA; wetland conditions do not currently exist in this area due to agricultural and
roadside ditches.
Insufficient water is currently available to the mitigation site for coastal marsh hydrology
due to ground elevations which allow infiltration and surface runoff losses.
4. The proposed mitigation plan involves excavation of the mitigation area to elevations
approximating those of the coastal marsh Reference Ecosystem, which will significantly
reduce infiltration losses and create the required hydrology for coastal marsh wetlands.
5. Since excavation for mitigation purposes could potentially adversely impact existing
wetland by increasing groundwater outflow from those areas, a forested upland buffer
strip has been preserved as a part of the mitigation plan to minimize groundwater flow
from those areas.
6. Existing ditches on the southern side of the property will be extended to connect the
converted area to Cowells Creek and Buckskin Creek. This will maintain hydraulic
connectivity with the adjoining creeks, thereby providing the mitigation site with
inundation by tidal waters.
7. After mitigation, tidal influx from adjoining creeks as well as precipitation will provide
sufficient water to sustain the coastal marsh system and offset losses from
evapotranspiration and increased surface water runoff.
8. Following grading and hydrological modifications, the site can be planted with appropriate
vegetation to create a coastal marsh with functions similar to the Reference Ecosystem.
9. A total of 3.58 credits can be obtained by the proposed mitigation project on the Casey
Tract site. Using the US EPA's guidelines for mitigation credits, 1.83 credits can be
obtained from coastal marsh creation and 0.40 credits from forested wetland

preservation, and 1.19 credits from coastal marsh preservation. In addition, it is proposed
' that 0.16 credits be obtained from forested upland preservation.
It is recommended that the proposed mitigation plan be approved and that the
' implementation plan be initiated by NCDOT. This final plan will include planting specifications
and design and construction drawings for the mitigation site.

TOTALS 8.4 625.2
COMPOSITE CURVE NUMBER = 625.2 / 8.4 = 74
' B. Determination of minimum precipitation event necessary to generate runoff:
' Assumption: Initial abstractions .2 x total maximum retention
Q =[ P-.2S]2 /[ P+.8S]
' where Q is runoff (in inches)
P is precipitation in inches
and S is total maximum retention; S = (1000/CN) - 10 = (1000/74) - 10 = 3.51
Set Q = 0 and solve for P:
' 0 = [ P-.2(3.51)]2 /[ P+.8(3.51)]
0 = [P - 0.702]2
P = 0.702 inches
' Therefore, precipitation events greater than 0.702 inches yield runoff.

1. Elevation: Excellent: the elevation of the
mitigation area will be graded to similar elevations and slope
' as the Reference Ecosystem.
YES NO N/A
' a. Have biological Benchmarks
been established? x
' b. Is there a grading plan? x
c. Is grading plan specific? x
' d. Is discing proposed after
grading and/or prior
' to planting?
a. Biological benchmarks are elevation, vegetation and hydrology of
' Reference Ecosystem.
b. Specific grading plans will be in implementation / final
mitigation plan.

' 2. Describe provisions for Drainage: To be determined;
' will be included in the final mitigation plan.
3. Describe Erosion Control Measures:
' This is a low energy system with irregular wind tides and most of
the excavation will be below the grade of the surrounding areas.
Erosion should be minimal. Specific erosion control measures will
' be included in final mitigation plan. The proposed erosion and
sedimentation control measures should effectively control any
erosion from occurring until the site has naturally stabilized.
' (See Draft Mitigation Plan - Section 5.5)
t 4. Describe management of Human Impacts: To be
determined depending on final dispensation. This may include
fencing.

5. Describe management of Herbivory/Noxious Plants:

D. Will this site have the opportunity
to function as planned? x
Describe: Site is expected to be preserved as a
mitigation site with little or no disturbance (See C above).
E. Describe how this project rates ecologically:
Excellent:
This site will exhibit habitat zonation, with adjacent forested
and riverine wetlands and uplands. Also, existing adjacent coastal
