RE: Request from NCDOT to construct a pedestrian and bicycle pathway to help connect the Coastal Studies
Institute to the Town of Manteo through the NCDOT Roanoke Island Visitor Information Center and Rest Area
in Dare County.

Hello Randy, Leilani, Ginny and Todd,

The attached application for a Major Modification of CAMA Permit No. 24-08 from NCDOT and the Coastal
Studies Institute was circulated last week to state and federal agencies for review and comment. This includes
other representatives from your agency that routinely receive requests for comments from DCM (Ken Pace
(NCDOT), Garcy Ward (DWR), and Tracey Wheeler (USACE). Although you do not usually receive CAMA
permit applications for review and comment, due to the previous involvement of you or your agency with the
Roanoke Island Visitor Center Mitigation Site, your comments are also requested.

Please find attached three documents in pdf that comprise the application. I will send the DCM Field
Investigation Report and background documents from the DCM files for the Roanoke Island Visitor Center
Mitigation Site in a subsequent e-mail, as the file was too big to send everything together.

Please let me or Greg Daisey know if you have any questions or concerns.

Sincerely,

Cathy Brittingham

Note:
This mitigation plun replaces the previotts mitigation plans for this project.
1.0 Introduction
The North Cazolina Department of Transportation (NCDOT) proposes to construct the Roanoke
Island Visitor Center/Rest Area along the new location portion of US 64-264 (Manteo Bypass)
currently under construction as TIP No. R-2» 1 between the Croatan Sound and the US 64/NC
34� intersection in Dare County. The proposed right-of-way will be approximately 9.2 ac.
I.1 Wetland Resources
Wetlands were delineated by Environmental Professionals using the "Corps of Engineers
Wetlands Delineation Manual" (1987). The delineation was verified by Tom Walker with the
U.S. Army Corps of Engineers on June 1, 1999.
Impacts to jurisdictional wetlands as a result of construction of the Roanoke Island Visitor
Center/Rest Area consist of a total of 1.1 � acres of permanent wetland impacts which consist of
0.82 acres of fill, 0.18 ac of isolated wetlands, and 0.15 acres due to mechanized cleazing. There
will also be 0.01 acres of fill in surface waters. There will be 145.5 linear feet of impacts to a
previously dredged channel located within the project area.
1.2 Summary of Mitigation
Avoidance and minimization measures taken during ttie project planning, review, and design
phases are described in the permit modification for TIP No. R-2551 dated February 23, 2001.
Wetland compensation for the Visitor Center/ Rest Area will be accomplished by restoration,
creation, and preservation onsite. NCDOT plans to mitigate for 1.15 ac. of wetland impacts
through on-site restoration of 0.11 ac Q:1) and creation of 1.66 aa (1: i) by removal of the
portions of the associated fill from the borrow pit that was once onsite and vegetating with
species matching the tazget wetland community. NCDOT requests a 1:1 ratio for creation due to
the high probability of success for extending adjacent wetland boundaries. NCDOT will
preserve 1.29 aa (5:1) of estuarine fringe on the Visitor Center/ Rest Area property.
Additionally, NCDOT will debit 1.36 ac (5:1) of forested wetland preservation from the Mashoes
Road Mitigation site in Daze County. Per conversations with resources agencies, 1,003.9 ft of
riparian buffers along the stream located within the project area will be re-vegetated with the
vegetation mix used for the wetland communities as compensatory mitigation for impacts to
Waters of the U.S. classified as SA Waters. The buffers will range from vazious widths that
extend to NCDOT property limits.

2.0 Roanoke Island Visitor Center/Rest Area Mitigation Site
The purpose of this report is to document the existing site conditions at the location of the
proposed Visitor Center/Rest Area, to describe the wetland restoration, creation, preservation,
and to establish the monitoring for the Roanoke Island Visitor Center/Rest Area Mitigation Plan.
This plan includes on-site wetland restoration and creation associated with the borrow pit / spoil
basin that previously existed onsite. As described eazlier, the 0.11 ac.(South Tract) of on-site
wetland restoration and 1.66 ac (North Tract 0.89 ac, South Tract 0.77 ac) of creation is proposed
as a portion of the required mitigation for Visitor Center/Rest Area. As requested by regulatory
agencies, 1,003.9 ft of riparian buffers along the stream ]ocated within the project area will be re-
vegetated.
2.1 Site Descriptions
Two tracts compose the onsite mitigation offered as compensation for impacts resulting from the
construction of the proposed Roanoke Island Visitor Center/ Rest Area. The South Tract is the
same property as the proposed Roanoke Island Visitor Center/ Rest Area will be constructed.
This tract is located south of the new location portion of US 64-264 (Manteo Bypass) currently
under construction between the Croatan Sound and the US 64/NC 345 intersection. The North
Tract is located approximately 600 ft. north of the proposed Roanoke Island Visitor Center/ Rest
Area (see Figure 1)
Sauth Tract
The existing site is approximately 92 ac in size. The majority of the property was used as a
borrow pit and spoil basin. Since that time, the basin walls have been pushed in and the spoil
material has been mixed with materiai from the berm that once enclosed the basin. The change
in slope across the site is from 1.5 feet above mean sea level (msl) to 5.0 feet above msl.
The wetland azea east of the borrow pit is chazacterized as an estuazine fringe forest community.
Dominant vegetation present in this community includes loblolly pine (Pinus taeda), red bay
(Persea borbonia), wax myrtle (Myrica cerifera), red maple (Acer rubrum), greenbrier (Smilcix
sp.), and American holly (Ilex opaca). The wetland area west of the borrow pit has the same
vegetation as the east side, with the exception of less loblolly pine and silverling (Baccharis
halimifolia) is the dominant vegetation.
The soils in this area are mapped by the Soil Survey of Dare County (NRCS, 1992) as the
Baymeade-Icaria-Johns association. However, Urban fill is the dominant soil type in the study
area, primarily associated with the bonow pit. Baymeade fine sand, Leon fine sand, and
Belhaven muck aze also located within the project study area.

Approximately 1200 ft of a tributary to the Croatan Sound runs along the eastern and southern
boundaries of the NCDOT property line. T'his stream has been channelized and ripazian buffer
vegetation is sparse and in some areas nonexistent.
North Tract
The existing site is 1.02 ac in size. The majority of the property was used as a borrow pit and
spoil basin. Since that time, the basin walls have been pushed in and the spoil material has been
mixed with material from the berm that once enclosed the basin. The change in slope across the
site is from 1.� feet above mean sea level (msl) to 4.0 feet above msl.
A portion of the remaining borrow piU spoil basin located west of the North Tract has been
proposed for wetland mitigation by Dare County for impacts resulting from the construction of
the proposed Daze County Justice Facility. The wetland area east of the North Tract is
characterized as an estuarine fringe shrub community that quickly grades into a tidal mazsh
community. Dominant vegetation present in the estuarine fringe community includes silverling
(Baccharis halimifolia) loblolly pine (Pinus taeda), red bay (Persea bor6onia), wax myrtle
(Myrica cerifera), red maple (Acer rubrum), greenbrier (Smilax sp.), American holly (Ilex
opaca), and sweet gum (Liquidambar styraciflua). Dominant vegetation present in the tidal
marsh community includes black needlerush (Juncus roemerianus), saltmeadow cordgrass
(Spartina patens), and cattaiis (Typha angustifolia)
The soils in this azea are mapped by the Soil Survey of Daze County (NRCS, 1992) as the
Baymeade-Icaria-Johns association. However, Urban fill is the dominant soil type in the study
area, primazily associated with the borrow pit. Baymeade fine sand, Leon fine sand, Belhaven
muck, and Hobonny muck are also located within the project study area.
2.2 Methodology
The goal of the mitigation plan is to establish a wetland community classified as Estuarine
Fringe. The proposed Visitor Center/ Rest Area Mitigation Sites (North and South Tracts) will
provide 1.77 ac of on-site wetland restoration/creation by removal of the existing fill associated
with the borrow pit/spoil basins that were previously onsite. Proposed onsite wetland mitigation
for the South Tract is shown in Figure 2. Stream stabilization in riparian buffers is illustrated by
Figure 3. Figure 4 provides proposed onsite wetland mitigation for the North Tract.
Approximately 1.0-3.0 ft. of fill material will be graded down to the elevation of the adjacent
jurisdictional wetlands. The area will be disked and ripped as necessary to reduce compaction.
The communities will be planted with species typical of the tazget community in a random mix
based on availability (see Table 1). The planting will occur on 8 foot centers with a density of
680 stems per acre. The planting ratio will be approximately 70% shrub and 30% tree species.
Stream stabilization will be accomplished through re-vegetating riparian buffers along 1,003.9ft
of the stream located within NCDOT property limits. The buffer widths will vary from

%
approximately 9 ft to 65 ft and will be planted with the same species mix, density, and planting
ratio of those to be planted in the wetland community.

23 Monitoring
var.
South Tract
Hydrologic monitoring will occur throughout the growing season in the wetland areas by using
40-inch groundwater gauges. Two groundwater gauges wil] be placed in the restored Estuarine
Fringe area and groundwater gauges will be placed in the creation Estuarine Fringe area. Four
groundwater gauges will be placed in the existing Estuazine Fringe community as reference
gauges. Hydrologic success criteria will be based on the establishment of hydrologic conditions
similaz in frequency, duration and depth to those documented in the existing reference wetlands
adjacent to the azeas being restored. Similaz hydrologic frequency, duration and depth shall be
determined as being within 20% of the respective reference wetlands established on the eastem
and western side ofthe Roanoke Island Visitor Center and Rest Area.
Vegetation monitoring will consist of two plot(s) for the Estuazine Fringe community. Stem
count and species composition will be recorded annually at the end of the growing season.
Success will be based on survival of 320 stems per acre in yeaz three with a tazget survival of 260
stems per year in yeaz five. Visual observation of plant establishment will be recorded using
photo reference points.
North Tract
Hydrologic monitoring will occur throughout the growing season in the wetland azeas by using
40-inch groundwater gauges. Two groundwater gauges will be placed in the creation Estuarine
Fringe azea. One groundwater gauge will be placed in the existing Estuazine Fringe community
as a reference gauge. Hydrologic success criteria will be based on the establishment of
hydrologic conditions similaz in frequency, duration and depth to those documented in the
existing reference wetlands adjacent to the azeas being restored. Similaz hydrologic frequency,
duration and depth shall be determined as being within 20% of the respective reference wetland
established on the eastern side of the North Tract.

Vegetation monitoring will consist of two plot(s) for the Estuazine Fringe community. Stem
count and species composition will be recorded annual(y at the end of the growing season.
Success will be based on survival of 320 stems per acre in year three with a tazget survival of 260
stems per year in year five. Visual observation of plant establishment will be recorded using
photo reference points.
Riparian Buffers
Vegetation that is not planted in wetland restoration or creation areas will be monitored
pictorially and photos wiil be provided at annual monitoring meetings.
2.4 Mitigation Credit Ratios
The following table outlines the credit ratios and calculations used for wetland mitigation due to
impacts resulting from construction ofthe Roanoke Island Visitor Center/Rest Area.
2.5 Final Dispensation of Property
NCDOT will retain ownership of the mitigation site until all monitoring requirements are
fuilfilled and an appropriate recipient is identified. If and when the deed is transferred,
restrictions will be placed on the property to ensure protection in perpetuity.

Mr. Huggett:
As you are aware, the Department has monitored the Roanoke Island Visitors Center since its
construction in March of 2002. I,ocated in Dare County, adjacent to the US 64-264 Manteo
Bypass, this site provides 0.1I acres of wetland restoration, 1.66 acres of estuarine fringe
creation, and 1.29 acres of estuarine preservation for impacts associated with the K-4003WM
project. The wetland restoration and creation azeas were constructed and revegetated with
appropriate hardwood species. Per the permit requirements, NCDOT proposed to monitor the
Roanoke Island Visitors Center mitigation site for five yeazs or until success criteria were met;
with hydrological and vegetation monitoring conducted each year. After each growing season,
annual monitoring reports were submitted to the appropriate regulatory agencies via the Natural
Environment Section (NES) website:
http://tivtivrv ncdot org/doh/precnnstr•uct/pe/neu/Nlonitori�/MonitaringReports hdnl
A site visit was held on April 23, 2007 with the regulatory agencies to address continued
problems with planted hardwood vegetation. Based on that meeting, it was agreed that NCDOT
would plant the remaining bare areas of the site with elevation appropriate marsh species. The
mix of these marsh species and sparse tree/shrub species is expected to more closely mimic the
impacted communities (see e-mail in Appendix B of the monitoring reports). The planted areas
would then be monitored based on accepted NMFS guidelines. The groundwater gauges were
removed at this time.

The vegetation success of the Roanoke Island Visitors Center site was determined in accordance
with NMFS Guidelines. After four years of marsh vegetation monitoring, the percent o� targel
species frequency is 83% and Yhe vegetative cover scale value is 4.8. Annual monitoring data is
provided within the aanual monitoring reports submitted between 2008 and 2011.
A site visit was conducted on April 18�h, 2012 with the regulatory agencies and NCDOT
personnel present. It was determined �t that meeting that the site success criteria had been met
and that no further monitoring would be required. NCDOT requests that the appropriate resource
agencies provide written documentation stating that no further monitoring is required and that the
site is closed. If you have any questions about this project, please contact Mr. Randy Griffin at
