Hi Cathy,
Paul and I visited this mitigation site with the NCDOT and the other permitting agencies on
April 18, 2012 to verify that it has met the criteria required for close out. The annual
report for the site indicates that 83% of the vegetation plots contain the target species,
with an average scale value of 4.8. During the site visit, we determined that the report
appears accurate. We did observe a few bare spots remaining in the site, however, as noted
in DDT's report, the vegetation appears to be spreading and filling in those areas.
Therefore, I recommend that we authorize the NCDOT to discontinue monitoring of the site and
close it out. Please let me know if you have any questions or concerns.
Thanks,
Stephen

Mr. Huggett:
As you are aware, the Department has monitored the Roanoke Island Visitors Center since its
construction in March of 2002. Located in Dare County, adjacent to the US 64-264 Manteo
Bypass, this site provides 0.11 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 areas 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 years 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://www.ncdot.org/doh/preconstruc t/pe/neu/Monitoring/MonitoringReports.html
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.

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for approximately 1.14-1.15 acres of estuarine fringe wetland forest impacts
and 145.5-146 LF of stream impacts. The Roanoke Island Visitor Center/ Rest Area
consists of 1.77 acres of estuarine fringe wetland forest restoration/creation, 1.29 acres
of estuarine fringe wetland forest preservation, and 1003.9 LF of riparian buffer. The
Roanoke Island Site was constructed in 2002 and this report details the monitoring
activities during the 2011 growing season.
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).
The planted areas would then be monitored based on accepted NMFS guidelines. The
groundwater gauges were removed at this time.
The preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas will
continue to be provided to show the progression of the area returning to its original
state. Photo documentation of the riparian buffer area is also provided per the
agencies request.
NCDOT will continue to monitor vegetation at the Roanoke Island Mitigation Site in
2012.

1.0 INTRODUCTION
1.1 Project Description
The Roanoke Island Site serves as onsite mitigation for the Roanoke Island Visitor
Center/Rest Area, located adjacent to the new US 64-264 Manteo Bypass. The site is
divided into two tracts; the "south" tract is on the same property as the Visitor Center
and the "north" tract is located approximately 600 feet north of the Visitor Center (Figure
1). The mitigation is associated with Project 8.1052501, TIP Numbers K-4003 and R-
2551 .
The site is designed to provide 0.11 acres of restoration (1:1) and 1 .66 acres of creation
(1 :1) of Estuarine Fringe wetlands. The site also includes 1.29 acres (5:1) of estuarine
preservation. In addition, approximately 1,004 feet of riparian buffer was planted with
the same vegetation mix as that used in the wetland zones. The width of the buffer
zone varies between 9 and 65 feet based on NCDOT property limits. The construction
plan for the wetland sites involved grading the former borrow pit areas to meet the
elevations of adjacent jurisdictional wetlands.
1.2 Purpose
In order to demonstrate successful mitigation, vegetative monitoring must be conducted
for a minimum of five years or until success criteria are fulfilled. Success criteria are
based on National Marine Fisheries Service guidelines. The following report details the
results of the marsh vegetation monitoring during 2011 at the Roanoke Island Mitigation
Site. Hydrologic monitoring is no longer required for this site.

2.0 VEGETATION: ROANOKE ISLAND VISITOR CENTER
(YEAR 4 MONITORING)
2.1 Success Criteria
The vegetative marsh success of the wetland site will be determined in accordance with
NMFS Guidelines. Monitoring plots found to be located within the open water channel
will not be evaluated, and will not count toward the final count of plots. The vegetation
component of the wetland site will be deemed successful if the following criteria are
met:
1 . At year five, the average of all plots should have a scale value of 5 (>75%
vegetation cover) consisting of wetland herbaceous species, not including any
invasive species.
2. A minimum of 70% of the plots shall contain the target (planted) species.
2.2 Description of Species
The following marsh grass species were planted in the Wetland Creation and
Restoration Areas:
Juncus roemerianus, Black Needle Rush
Spartina patens, Saltmeadow Cordgrass
Cladium jamaicense, Sawgrass

Site Notes: The planted marsh grass species are surviving and are continuing to
spread. The sawgrass plantings have not survived as well as the other two planted
marsh grass species. Baccharis, marsh-elder, and wax myrtle were the most dominate
woody species noted throughout the site. NCDOT has been treating the phragmites
that is located on site and will continue treatments throughout the monitoring period.
Phragmites was only noted in isolated areas and with just a few stems. The herbicide
treatments have been controlling the spread of the phragmites.
2.4 Conclusions
Percent Frequency of Target Species 83%
Frequency of 70% required.
Vegetation Cover Scale Value 4.8
Scale Value of 5.0 required for year 5.
Approximately 1.8 acres of this site was planted in the wetland restoration and creation
areas in March 2002. The site was replanted in February 2004 and March 2005. In
March 2006, NCDOT applied 1 ton of gypsum, 1 ton of hydrated lime, tilled the site with
a walk-behind-tiller, and planted bareroot seedlings on four-foot centers. This was an
attempt to get a greater survival rate of planted hardwood vegetation on site. The 2006
vegetation monitoring revealed that the steps taking to get a greater survival rate of
planted hardwood vegetation on site failed. The planted hardwood vegetation was
surviving in very low numbers. A few baldcypress, swamp blackgum, and wax myrtle
were noted surviving. The soluble salt levels on site are so high that it has become
impossible to get these hardwood species to survive in large numbers. An onsite
agency meeting was held on April 23, 2007 for NCDOT to propose planting elevation
appropriate marsh grasses in the remaining bare areas of the site and to continue
monitoring under the NMFS Guidelines for the success criteria of the site. NCDOT
planted the site with marsh grasses in May 2008.
During construction of the mitigation site in 2002, approximately 0.29 acres of wetland
preservation area was inadvertently cleared. These mechanized clearing areas are
adjacent to the creation areas on the North and South Tracts. This activity was
referenced in a letter to the Corps dated March 6, 2002. Per the letter to the Corps, the
preservation areas have been replanted. NCDOT will continue to provide photo
documentation of the mechanized clearing areas to show the progression of the area
returning to its original state.
According to the July 2001 Roanoke Island Visitor Center/Rest Area Mitigation Plan, the
riparian buffers are to be monitored pictorially and photos will be provided at the annual
monitoring meeting. Photos of the riparian buffers are included with this report.
NCDOT proposes to continue vegetation monitoring at the Roanoke Island Visitors
Center Mitigation Site.

3.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
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).
The planted areas would then be monitored based on accepted NMFS guidelines. The
groundwater gauges were removed at this time.
The preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas will
continue to be provided to show the progression of the area returning to its original
state.
For 2011 marsh grass vegetation monitoring, the target species and scale values were
83% and 4.8, respectively. The planted vegetation is surviving and spreading
throughout the site. NCDOT proposes to continue vegetation monitoring at the
Roanoke Island Mitigation Site
NCDOT proposes to continue the vegetation monitoring for 2012.

Hello all,
Based on our meeting last Monday (April 23) NCDOT is going to proceed with planting
elevation appropriate marsh grasses (black needle rush, sawgrass and patens) in the
remaining bare areas of the Roanoke Island Visitor's Center Mitigation Site. Due to
ordering plant material, this will not happen until next spring.
DOT will treat any phragmites in the site this summer and fall.
Our typical monitoring approach for marsh sites is to follow NMFS guidelines which
specify random plots, target species coverage, and overall coverage. This is a 5 year
monitoring period but we would propose an early closeout if coverage meets the
required success criteria.
According to the permits (404, 401, DCM) the project impacts were
1.14-1.15 acres of estuarine fringe wetland forest and 145.5 -146 LF of stream. All
three permits refer to the May 2001 mitigation plan for the Roanoke Island Visitor
Center. Included in this document (and in the 401 permit) is a table with a breakdown
of mitigation activities at the site. This table shows a total of
1 .77 acres estuarine fringe restoration/creation, 1 .29 acres estuarine fringe
preservation, 1 .36 acres forested wetland preservation, and 1003.9 LF riparian buffer.
There was a lot of discussion about this proposal as being "out-of-kind" mitigation.
Personally I feel that the combination of marsh grasses and sparse tree/shrub
vegetation is exactly the same community that we were looking at in the preservation
areas (and the original impact area). This sparse tree/shrub vegetation consists of
planted species and volunteer species such as baccharis, pine, red maple, and wax
myrtle. Both sites are directly adjacent to tidal streams or sloughs which would put that
community at the lower elevation range of an estuarine fringe system. According to
Schafale and Weakley that lower range contains species from adjacent marshes.
Roanoke Island is used as an example of this system in their book.
I would propose that this existing mitigation site be used as was originally intended to
offset impacts caused by the construction of the entrance to the Visitor Center. This
would be contingent on the success of the marsh grasses that are planted next spring.
If you have any questions please call. Thank you.

SUMMARY
The following report summarizes the monitoring activities that have occurred in
the past year at the Roanoke Island Mitigation Site. The site was constructed to
serve as mitigation for approximately 1.14-1.15 acres of estuarine fringe wetland
forest impacts and 145.5-146 LF of stream impacts. The Roanoke Island Visitor
Center/ Rest Area consists of 1.77 acres of estuarine fringe wetland forest
restoration/creation, 1.29 acres of estuarine fringe wetland forest preservation,
and 1003.9 LF of riparian buffer. The Roanoke Island Site was constructed in
2002 and this report details the monitoring activities during the 2009 growing
season.
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). The planted areas would then be
monitored based on accepted NMFS guidelines. The groundwater gauges were
removed at this time.
The preservation areas that were inadvertently cleared during construction of the
site in 2002 were replanted. Photo documentation of the mechanized clearing
areas will continue to be provided to show the progression of the area returning
to its original state.
Photo documentation of the riparian buffer area is also provided.
NCDOT will continue to monitor vegetation at the Roanoke Island Mitigation Site.

1.0 INTRODUCTION
1.1 Project Description
The Roanoke Island Site serves as onsite mitigation for the Roanoke Island
Visitor Center/Rest Area, located adjacent to the new US 64-264 Manteo
Bypass. The site is divided into two tracts; the "south" tract is on the same
property as the Visitor Center and the "north" tract is located approximately 600
feet north of the Visitor Center (Figure 1). The mitigation is associated with
Project 8.1052501, TIP Numbers K-4003 and R-2551.
The site is designed to provide 0.11 acres of restoration (1 :1) and 1.66 acres of
creation (1 :1) of Estuarine Fringe wetlands. The site also includes 1.29 acres
(5:1) of estuarine preservation. In addition, approximately 1,004 feet of riparian
buffer was planted with the same vegetation mix as that used in the wetland
zones. The width of the buffer zone varies between 9 and 65 feet based on
NCDOT property limits. The construction plan for the wetland sites involved
grading the former borrow pit areas to meet the elevations of adjacent
jurisdictional wetlands.
1.2 Purpose
In order to demonstrate successful mitigation, vegetative monitoring must be
conducted for a minimum of five years or until success criteria are fulfilled.
Success criteria are based on National Marine Fisheries Service guidelines. The
following report details the results of the marsh vegetation monitoring during
2009 at the Roanoke Island Mitigation Site. Hydrologic monitoring was not
required for this site

2.0 VEGETATION: ROANOKE ISLAND VISITOR CENTER
(YEAR 2 MONITORING)
2.1 Success Criteria
The vegetative marsh success of the wetland site will be determined in
accordance with NMFS Guidelines. Monitoring plots found to be located within
the open water channel will not be evaluated, and will not count toward the final
count of plots. The vegetation component of the wetland site will be deemed
successful if the following criteria are met:
1. At year five, the average of all plots should have a scale value of 5 (>75%
vegetation cover) consisting of wetland herbaceous species, not including
any invasive species.
2. A minimum of 70% of the plots shall contain the target (planted) species.
2.2 Description of Species
The following marsh grass species were planted in the Wetland Creation and
Restoration Areas:
Juncus roemerianus, Black Needle Rush
Spartina patens, Saltmeadow Cordgrass
Cladium jamaicense, Sawgrass

Approximately 1 .8 acres of this site was planted in the wetland restoration and
creation areas in March 2002. The site was replanted in February 2004 and
March 2005. In March 2006, NCDOT applied one ton of gypsum, one ton of
hydrated lime, tilled the site with a walk-behind-tiller, and planted bareroot
seedlings on four-foot centers. This was an attempt to get a greater survival rate
of planted hardwood vegetation on site. The 2006 vegetation monitoring
revealed that the steps taking to get a greater survival rate of planted hardwood
vegetation on site failed. The planted hardwood vegetation was surviving in very
low numbers. A few bald cypress, swamp blackgum, and wax myrtle were noted
surviving. The soluble salt levels on site are so high that it has become
impossible to get these hardwood species to survive in large numbers. An onsite
agency meeting was held on April 23, 2007 for NCDOT to propose planting
elevation appropriate marsh grasses in the remaining bare areas of the site and
to continue monitoring under the NMFS Guidelines for the success criteria of the
site. NCDOT planted the site with marsh grass species in May 2008.
During construction of the mitigation site in 2002, approximately 0.29 acres of
wetland preservation area was inadvertently cleared. These mechanized
clearing areas are adjacent to the creation areas on the North and South Tracts.
This activity was referenced in a letter to the Corps dated March 6, 2002. Per
the letter to the Corps, the preservation areas have been replanted. NCDOT will
continue to provide photo documentation of the mechanized clearing areas to
show the progression of the area According to the July 2001 Roanoke Island
Visitor Center/Rest Area Mitigation Plan, the riparian buffers are to be monitored
pictorially and photos will be provided at the annual monitoring meeting. Photos
of the riparian buffers are attached with this report.
returning to its original state.
NCDOT proposes to continue vegetation monitoring at the Roanoke Island
Visitors Center Mitigation Site.

3.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
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

sparse tree/shrub species is expected to more closely mimic the impacted
communities (see e-mail in Appendix B). The planted areas would then be
monitored based on accepted NMFS guidelines. The groundwater gauges were
removed at this time.
The preservation areas that were inadvertently cleared during construction of the
site in 2002 were replanted. Photo documentation of the mechanized clearing
areas will continue to be provided to show the progression of the area returning
to its original state.
For 2009 marsh grass vegetation monitoring, the target species and scale values
were 65.0% and 4.4, respectively. The planted vegetation is surviving and
spreading throughout the site. NCDOT proposes to continue vegetation
monitoring at the Roanoke Island Mitigation Site.
NCDOT proposes to continue the vegetation monitoring for 2010.

Hello all,
Based on our meeting last Monday (April 23) NCDOT is going to proceed with planting
elevation appropriate marsh grasses (black needlerush, sawgrass and patens) in the
remaining bare areas of the Roanoke Island Visitor's Center Mitigation Site. Due to
ordering plant material, this will not happen until next spring.
DOT will treat any phragmites in the site this summer and fall.
Our typical monitoring approach for marsh sites is to follow NMFS guidelines which
specifies random plots, target species coverage, and overall coverage. This is a 5 year
monitoring period but we would propose an early closeout if coverage meets the
required success criteria.
According to the permits (404,401,DCM) the project impacts were
1.14-1 .15 acres of estuarine fringe wetland forest and 145.5 -146 LF of stream. All
three permits refer to the May 2001 mitigation plan for the Roanoke Island Visitor
Center. Included in this document (and in the 401 permit) is a table with a breakdown
of mitigation activities at the site. This table shows a total of
1.77 acres estuarine fringe restoration/creation, 1.29 acres estuarine fringe
preservation, 1.36 acres forested wetland preservation, and 1003.9 LF riparian buffer.
There was a lot of discussion about this proposal as being "out-of-kind" mitigation.
Personally I feel that the combination of marsh grasses and sparse tree/shrub
vegetation is exactly the same community that we were looking at in the preservation
areas (and the original impact area). This sparse tree/shrub vegetation consists of
planted species and volunteer species such as baccharis, pine, red maple, and wax
myrtle. Both sites are directly adjacent to tidal streams or sloughs which would put that
community at the lower elevation range of an estuarine fringe system. According to
Schafale and Weakley that lower range contains species from adjacent marshes.
Roanoke Island is used as an example of this system in their book.
I would propose that this existing mitigation site be used as was originally intended to
offset impacts caused by the construction of the entrance to the Visitor Center. This
would be contingent on the success of the marsh grasses that are planted next spring.
If you have any questions please call. Thank you.

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for approximately 1.14-1.15 acres of estuarine fringe wetland forest impacts
and 145.5-146 LF of stream impacts. The Roanoke Island Visitor Center/ Rest Area
consists of 1.77 acres of estuarine fringe wetland forest restoration/creation, 1.29 acres
of estuarine fringe wetland forest preservation, and 1003.9 LF of riparian buffer. The
Roanoke Island Site was constructed in 2002 and this report details the monitoring
activities during the 2008 growing season.
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).
The planted areas would then be monitored based on accepted NMFS guidelines. The
groundwater gauges were removed at this time.
The preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas will
continue to be provided to show the progression of the area returning to its original
state.
Photo documentation of the riparian buffer area is also provided.
NCDOT will continue to monitor vegetation at the Roanoke Island Mitigation Site.

1.0 INTRODUCTION
1.1 Project Description
The Roanoke Island Site serves as onsite mitigation for the Roanoke Island Visitor
Center/Rest Area, located adjacent to the new US 64-264 Manteo Bypass. The site is
divided into two tracts; the "south" tract is on the same property as the Visitor Center
and the "north" tract is located approximately 600 feet north of the Visitor Center (Figure
1). The mitigation is associated with Project 8.1052501, TIP Numbers K-4003 and R-
2551.
The site is designed to provide 0.11 acres of restoration (1 :1) and 1.66 acres of creation
(1 :1) of Estuarine Fringe wetlands. The site also includes 1 .29 acres (5:1) of estuarine
preservation. In addition, approximately 1 ,004 feet of riparian buffer was planted with
the same vegetation mix as that used in the wetland zones. The width of the buffer
zone varies between 9 and 65 feet based on NCDOT property limits. The construction
plan for the wetland sites involved grading the former borrow pit areas to meet the
elevations of adjacent jurisdictional wetlands.
1.2 Purpose
In order to demonstrate successful mitigation, vegetative monitoring must be conducted
for a minimum of five years or until success criteria are fulfilled. Success criteria are
based on National Marine Fisheries Service guidelines. The following report details the
results of the marsh vegetation monitoring during 2008 at the Roanoke Island Mitigation
Site. Hydrologic monitoring was not required for this site

2.0 VEGETATION: ROANOKE ISLAND VISITOR CENTER
(YEAR 1 MONITORING)
2.1 Success Criteria
The vegetative marsh success of the wetland site will be determined in accordance with
NMFS Guidelines. Monitoring plots found to be located within the open water channel
will not be evaluated, and will not count toward the final count of plots. The vegetation
component of the wetland site will be deemed successful if the following criteria are
met:
1. At year five, the average of all plots should have a scale value of 5 (>75%
vegetation cover) consisting of wetland herbaceous species, not including any

2.4 Conclusions
Percent Frequency of Target Species 77%
Frequency of 70% required.
Vegetation Cover Scale Value 3.4
Scale Value of 5.0 required for year 5.
Approximately 1 .8 acres of this site was planted in the wetland restoration and creation
areas in March 2002. The site was replanted in February 2004 and March 2005. In
March 2006, NCDOT applied 1 ton of gypsum, 1 ton of hydrated lime, tilled the site with
a walk-behind-tiller, and planted bareroot seedlings on four-foot centers. This was an
attempt to get a greater survival rate of planted hardwood vegetation on site. The 2006
vegetation monitoring revealed that the steps taking to get a greater survival rate of
planted hardwood vegetation on site failed. The planted hardwood vegetation was
surviving in very low numbers. A few bald cypress, swamp blackgum, and wax myrtle's
were noted surviving. The soluble salt levels on site are so high that it has become
impossible to get these hardwood species to survive in large numbers. An onsite
agency meeting was held on April 23, 2007 for NCDOT to propose planting elevation
appropriate marsh grasses in the remaining bare areas of the site and to continue
monitoring under the NMFS Guidelines for the success criteria of the site. NCDOT
planted the site with marsh grasses in May 2008.
During construction of the mitigation site in 2002, approximately 0.29 acres of wetland
preservation area was inadvertently cleared. These mechanized clearing areas are
adjacent to the creation areas on the North and South Tracts. This activity was
referenced in a letter to the Corps dated March 6, 2002. Per the letter to the Corps, the
preservation areas have been replanted. NCDOT will continue to provide photo
documentation of the mechanized clearing areas to show the progression of the area
returning to its original state.
NCDOT proposes to continue vegetation monitoring at the Roanoke Island Visitors
Center Mitigation Site.
3.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
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).
The planted areas would then be monitored based on accepted NMFS guidelines. The
groundwater gauges were removed at this time.

il, .
The preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas wi II
continue to be provided to show the progression of the area returning to its original
state.
For 2008 marsh grass vegetation monitoring, the target species and scale values were
77.0% and 3.4, respectively. The planted vegetation is surviving and spreading
throughout the site. NCDOT proposes to continue vegetation monitoring at the
Roanoke Island Mitigation Site
NCDOT proposes to continue the vegetation monitoring for 2009.

Hello all,
Based on our meeting last Monday (April 23) NCDOT is going to proceed with planting
elevation appropriate marsh grasses (black needlerush, sawgrass and patens) in the
remaining bare areas of the Roanoke Island Visitor's Center Mitigation Site. Due to
ordering plant material, this will not happen until next spring.
DOT will treat any phragmites in the site this summer and fall.
Our typical monitoring approach for marsh sites is to follow NMFS guidelines which
specifies random plots, target species coverage, and overall coverage. This is a 5 year
monitoring period but we would propose an early closeout if coverage meets the
required success criteria.
According to the permits (404,401,DCM) the project impacts were
1.14-1.15 acres of estuarine fringe wetland forest and 145.5 -146 LF of stream. All
three permits refer to the May 2001 mitigation plan for the Roanoke Island Visitor
Center. Included in this document (and in the 401 permit) is a table with a breakdown
of mitigation activities at the site. This table shows a total of
1.77 acres estuarine fringe restoration/creation, 1.29 acres estuarine fringe
preservation, 1.36 acres forested wetland preservation, and 1003.9 LF riparian buffer.
There was a lot of discussion about this proposal as being "out-of-kind" mitigation.
Personally I feel that the combination of marsh grasses and sparse tree/shrub
vegetation is exactly the same community that we were looking at in the preservation
areas (and the original impact area). This sparse tree/shrub vegetation consists of
planted species and volunteer species such as baccharis, pine, red maple, and wax
myrtle. Both sites are directly adjacent to tidal streams or sloughs which would put that
community at the lower elevation range of an estuarine fringe system. According to
Schafale and Weakley that lower range contains species from adjacent marshes.
Roanoke Island is used as an example of this system in their book.
I would propose that this existing mitigation site be used as was originally intended to
offset impacts caused by the construction of the entrance to the Visitor Center. This
would be contingent on the success of the marsh grasses that are planted next spring.
If you have any questions please call. Thank you.

Hello,
You probably have this covered already, but would you please make sure that the next annual
monitoring report for the Roanoke Island Visitor Center in Dare County,TIP No. K-4003, includes
photographs of the approximately 1,004 feet of riparian buffers that were planted? The provision for
photo monitoring of the planted riparian buffers is found on page 6 of the Revised Roanoke Island
Visitor Information Center and Rest Area Mitigation Plan, dated July 2001.

Byron,
Melissa Carle and I have reviewed the attached proposal from NCDOT, and unfortunately, we have
concerns as outlined below. In addition,because the wetland impacts being mitigated were not CAMA
coastal wetlands,NCDOT should also consult with USACE and DWQ, at a minimum, before
proceeding with any new plantings or site work. It may even be worthwhile to conduct an inter-agency
meeting to make sure that all interested parties agree on the next steps. One approach would be to add
the mitigation site to the agenda of an eastern concurrence meeting day. Most of the concurrence
meeting dates have not been filled with projects recently.
DCM concerns
• The impacted wetlands were described in the CAMA permit modification as estuarine fringe
wetland forest with dominant vegetation including loblolly pine,red bay, wax myrtle,red maple,
greenbrier and American Holly. USACE and DWQ will need to determine if out-of-kind
mitigation with CAMA coastal wetlands is acceptable mitigation for these impacts.
• DCM agrees that NCDOT should not continue to re-plant the same tree species that have failed to
survive at the site in previous years. However, with the exception of Wax Myrtle, the species that
were planted are not the same species present in adjacent estuarine fringe communities.
According to the May 2001 mitigation plan, estuarine fringe wetlands adjacent to the site are
characterized by silverling (/Baccharis halimifolia/), loblolly pine (/Pinus taeda/), red bay(/Persea
borbonia/),Wax Myrtle (/Myrica cerifica/),Red Maple (/Acer rubrum/), and American Holly
(Alex opaca/). DCM would like to know how many volunteer trees and shrubs have become
established at the site and whether they mirror this reference community. These species are
probably much more appropriate for parts of the site that are graded higher than the nearby marsh.
Of these trees and shrubs, silverling (/Baccharis halimifolia/)is probably the most salt-tolerant
species and the most likely to become well-established at this site.
• If parts of the site are graded to the same level as nearby reference marshes,then DCM would be
supportive of planting coastal marsh species in these areas. DCM does not seem to have an
"as-built" report for this project to examine the grade. However,DCM does not support planting
sawgrass (/Cladium jamainscence/), given the high salt concentration in the soils. Black
needlerush (/Juncus roemerianus/) is the coastal marsh species best adapted to hypersaline soils
and is probably the most appropriate marsh species for this site. To maximize chances of
vegetation success, DCM recommends that DOT propose only planting black needlerush in the
lower areas. If other native marsh species can tolerate the conditions at the site, they will
eventually colonize from existing nearby marshes.
• The hydrologic success criteria are based upon reference wetlands adjacent to the areas being
restored. If the regulatory agencies approve NCDOT's proposal to plant CAMA coastal wetland
species within the wetland creation area, then new reference wetlands may need to be selected to
match the new vegetative community targeted for wetland creation. DOT needs to provide more
information about the vegetative composition of the current reference wetland.
• DCM does not necessarily agree that it is appropriate to plant CAMA coastal wetland species
1 of 2 2/13/2007 3:10 PM

within the preservation areas that were accidentally mechanically cleared in 2002. What
vegetative species were cleared? What species have since regenerated naturally into these areas?
Is the area at the correct elevation and position for CAMA coastal wetland species? DCM needs
more information.
• A 1:1 ratio for creation was allowed due to the high probability of succesifor extendinEsadjacent
wetland boundaries. Because the wetland creation areas are struggling to achieve success, it may
be necessary to increase the ratio for creation to compensate for the time delay between incurring
impacts and accomplishing successful mitigation. This should be discussed further with DCM,
DWQ, USACE and other interested agencies.
DCM is disappointed that the mitigation site has not yet achieved its success criteria, and we appreciate
NCDOT's efforts to seek solutions to make this site a success. DCM looks forward to working with
NCDOT,DWQ, USACE and other interested agencies to determine the appropriate course of action for
this mitigation site. Please let us know how you would like to proceed.
Sincerely,
Cathy Brittingham

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for the Roanoke Island Visitor Center/ Rest Area; approximately 1.77 acres of
impacts are mitigated for onsite and the remaining 1.36 acres of preservation were
debited from the Mashoes Road Mitigation Site. The Roanoke Island Site was
constructed in 2002 and this report details the fifth year of hydrology monitoring and first
year of vegetation monitoring following construction.
There are three gauges located in the north tract with two gauges in the constructed
area and one gauge in the reference area. There are eight gauges located in the south
tract with four gauges in the constructed area and four corresponding gauges in the
reference area. For the three north tract gauges, only one of the gauges met the 20%
saturation period for it's respective reference gauge. For the eight south tract gauges,
two of the gauges met the 20% saturation period for their respective reference gauges.
The two gauges that failed, would have met the 20% saturation period for it's
corresponding reference gauge had it not been for gauge malfunctions.
Data from the fifth year of hydrologic monitoring indicates that all eleven monitoring
gauges demonstrated saturation within 12 inches of the surface for at least 12.5% of the
growing season. Gauge RIST-7 (ref) was moved to a more suitable location based on
similar elevation in August 2005, and met saturation within 12 inches of the surface for
57.4% of the growing season.
This site was replanted with bareroot seedlings in March 2006. Due to high soluble salt
levels at the site, the hardwood vegetation is surviving in very low numbers. The
preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas will
continue to be provided to show the progression of the area returning to its original
state.
NCDOT will continue to monitor vegetation and hydrology at the Roanoke Island
Mitigation Site.

1.0 INTRODUCTION
1.1 Project Description
The Roanoke Island Site serves as onsite mitigation for the Roanoke Island Visitor
Center/Rest Area, located adjacent to the new US 64-264 Manteo Bypass. The site is
divided into two tracts; the "south" tract is on the same property as the Visitor Center
and the "north" tract is located approximately 600 feet north of the Visitor Center (Figure
1). The mitigation is associated with Project 8.1052501, TIP Numbers K-4003 and R-
2551.
The site is designed to provide 0.11 acres of restoration (1:1) and 1.66 acres of creation
(1:1) of Estuarine Fringe wetlands. The site also includes 1.29 acres (5:1) of estuarine
preservation. In addition, approximately 1,004 feet of riparian buffer was planted with
the same vegetation mix as that used in the wetland zones. The width of the buffer
zone varies between 9 and 65 feet based on NCDOT property limits. The construction
plan for the wetland sites involved grading the former borrow pit areas to meet the
elevations of adjacent jurisdictional wetlands.
1.2 Purpose
In order to demonstrate successful mitigation, hydrologic and vegetative monitoring
must be conducted for a minimum of five years or until success criteria are fulfilled.
Success criteria are based on federal guidelines for wetland mitigation and are
stipulated in the "Roanoke Island Visitor Center/ Rest Area Mitigation Plan" dated May
2001 (revised July 2001). These guidelines stipulate criteria for both hydrologic
conditions and vegetation survival. The following report details the results of hydrologic
and vegetative monitoring during 2006 at the Roanoke Island Mitigation Site.
Activities in 2006 reflect the fifth year of hydrology monitoring and the first year of
vegetation monitoring at the mitigation site. Included in this report are analyses of both
hydrologic and vegetative monitoring results, as well as local climate conditions
throughout the growing season.

2.0 HYDROLOGY
2.1 Success Criteria
While a constructed site must typically meet jurisdictional criteria of inundation or
saturation within 12 inches of the surface for at least 12.5% of the growing season,
NCDOT and consulting agencies agreed that other criteria might be the best indicator of
hydrologic success on this particular site. In accordance with the guidelines set forth by
the approved mitigation plans, hydrologic success is dictated by the hydrologic condition
of the reference wetlands adjacent to the sites. Monitoring gauges are located in both
the constructed and reference areas. The site is considered a hydrologic success if the
hydrologic frequency, duration and depth are within 20% of its respective reference
wetland.
The growing season in Dare County begins March 13 and ends November 25. The
dates correspond to a 50% probability that temperatures will drop to 28° F or lower after
4

March 13 and before November 25.1 The growing season is 258 days; therefore the
optimum duration for wetland hydrology is 32 days. While the monitoring gauges record
ground/surface water levels throughout the year, special attention is placed on water
levels during the 258-day growing season. In addition, local rainfall totals are monitored
to ensure that the site is functioning in normal climatic conditions.
2.2 Hydrologic Description
The site was constructed by grading the existing fill material down to meet the
elevations of existing reference wetlands. The removed fill material is associated with
borrow pit/ spoil basins that were previously onsite. Eleven monitoring gauges were
installed on the site in order to monitor the new hydrologic conditions. Three gauges
were located on the north tract and eight gauges were located on the south tract. Of
these, one gauge is located within the north tract reference wetland, while four gauges
are located within reference areas in the south tract. The success of the site is
determined by comparing the groundwater levels in the reference areas with those in
the constructed zones.
Site rainfall is monitored with a rainfall gauge located onsite. In addition, the recorded
data is compared to rainfall data at the Manteo Airport gauge in order to check the
accuracy of the measured data. The NC State Climate Office provided the Manteo
data. Figures 2 and 3 are monitoring gauge maps of the north and south tracts,
respectively.
2.3 Results of Hydrologic Monitoring
2.3.1 Site Data
Table 1 is a summary of the hydrologic monitoring results for both the north and south
tracts. The mitigation plan states that the hydrologic conditions of the constructed areas
must be within 20% of those in the reference areas. Figures 4 and 5 are
representations of the hydrologic monitoring results.
Appendix A contains a plot of the groundwater depth for each monitoring gauge. While
success of the site is based on reference wetlands and not the percentage of the
growing season that the groundwater is within 12 inches of the surface, the 12-inch line
is provided for reference. The number of days the water level was above this line is
also provided on each graph. Precipitation events, as recorded by the onsite rain
gauge, are included on each graph as bars.

2.3.2 Climatic Data
Figure 6 provides an evaluation of the local climate in comparison with historical data in
order to determine whether 2006 was "normal" in terms of climate conditions. The two
lines represent the 30th and 70th percentiles of monthly precipitation for Manteo, NC. The
bars are monthly rainfall totals for 2006. The historical data was collected from the State
Climate Office of North Carolina.
For the 2006 year the below average rainfall includes; February, March, August, and
October. January, April, May, June, and July experienced average rainfall. The months
of September and November experienced above average rainfall for the year. Overall
the site experienced average rainfall in 2006.
2.4 Conclusions
Data from the fifth year of hydrologic monitoring indicates that all eleven monitoring
gauges demonstrated saturation within 12 inches of the surface for at least 12.5% of the
growing season. Gauge RIST-7 (ref) was moved to a more suitable location based on
similar elevation in August 2005, and met saturation within 12 inches of the surface for
57.4% of the growing season.
RINT-1 met within the 20% saturation period, while RINT-2 did not meet the saturation
period for the corresponding reference gauge RINT-3. RIST-1 and RIST-4 did not
meet the 20% saturation period for their corresponding reference gauges. RIST-5 met
the 20% saturation period, meeting approximately 80% of the growing season with it's
corresponding reference gauge RIST-6. RINT-8 met the 20% saturation period by
exceeding the corresponding reference gauge. RIST-1 and RIST-4 experienced gauge
malfunctions during the growing season, however these gauges would have met the
20% saturation period for it's corresponding reference gauge had it not been for gauge
malfunctions.
NCDOT recommends that hydrologic monitoring continue on the Roanoke Island
Mitigation Site.

3.0 VEGETATION: ROANOKE ISLAND VISITOR CENTER
(YEAR 1 MONITORING)
3.1 Success Criteria
The success criteria state that there must be a minimum of 320 trees per acre living for
at least three consecutive years. A minimum of 290 trees per acre living at year 4 and a
minimum of 260 trees per acre living at year 5.
3.2 Description of Species
The following tree species were planted in the Wetland Enhancement Area:
Taxodium distichum, Baldcypress
Myrica cerifera, Wax Myrtle
Persea palustris, Swamp Redbay
Nyssa sylvatica var. biflora, Swamp Blackgum
Gordonia lasianthus, Loblolly Bay
Chamaecyparis thyoides, Atlantic White Cedar
3.3 Results of Vegetation Monitoring
The 2006 vegetation monitoring revealed that very few hardwood species were
surviving. Baldcypress, swamp blackgum, and wax myrtles were noted surviving in
vegetation plots 1, 2, and 3. There were no trees surviving in vegetation plot 4.
Site Notes: Other species noted: Juncus sp., cattail, woolgrass, pine, golden rod, water
grass, Scripus americanus, Pluchea sp., sawgrass, phragmites, marsh-elder, and
Baccharis halimifolia.
3.4 Conclusions
Approximately 1.8 acres of the site were planted in the wetland restoration and creation
areas in March 2002. The site was replanted in February 2004 and March 2005. In an
attempt to achieve greater survival rate of planted hardwood vegetation on the site, the
following steps were conducted in March 2006. NCDOT applied treatment of 1 ton of
gypsum and 1 ton of hydrated lime. The site was tilled and planted with bareroot
seedlings on four-foot centers. The 2006 vegetation monitoring revealed that these
steps failed on the site. The planted hardwood vegetation were surviving in very low
numbers due to the high soluble salt levels on the site, however the baldcypress,
swamp blackgum, and wax myrtle were noted as surviving in small numbers.
13

During construction of the mitigation site in 2002, approximately 0.29 acres of wetland
preservation area was inadvertently cleared. These mechanized clearing areas are
adjacent to the creation areas on the North and South Tracts. This activity was
referenced in a letter to the Corps dated March 6, 2002. Per the letter to the Corps, the
preservation areas have been replanted. NCDOT will continue to provide photo
documentation of the mechanized clearing areas to show the progression of the area
returning to its original state.
NCDOT will coordinate with the resource agencies in 2007 to determine the appropriate
action that needs to be taken to provide the required mitigation at the Roanoke Island
Visitors Center.
4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
There are three gauges located in the north tract with two gauges in the constructed
area and one gauge in the reference area. There are eight gauges located in the south
tract with four gauges in the constructed area and four corresponding gauges in the
reference area. For the three north tract gauges, only one of the gauges met the 20%
saturation period for it's respective reference gauge. For the eight south tract gauges,
two of the gauges met the 20% saturation period for their respective reference gauges.
The two gauges that failed, would have met the 20% saturation period for it's
corresponding reference gauge had it not been for gauge malfunctions.
Data from the fifth year of hydrologic monitoring indicates that all eleven monitoring
gauges demonstrated saturation within 12 inches of the surface for at least 12.5% of the
growing season. Gauge RIST-7 (ref) was moved to a more suitable location based on
similar elevation in August 2005, and met saturation within 12 inches of the surface for
57.4% of the growing season.
This site was replanted with bareroot seedlings in March 2006. Due to high soluble salt
levels at the site, the hardwood vegetation is surviving in very low numbers. The
preservation areas that were inadvertently cleared during construction of the site in
2002 were replanted. Photo documentation of the mechanized clearing areas will
continue to be provided to show the progression of the area returning to its original
state.
NCDOT will continue to monitor the Roanoke Island Mitigation Site for hydrology and
vegetation. NCDOT will coordinate with the resource agencies in 2007 to determine the
appropriate action that needs to be taken to provide the required mitigation at the
Roanoke Island Visitors Center.

a 5.2 mile bridge extending across the Croa .n Sound.
Recomm- dations: RK&K did not loc. - •ocumentation referencin. a post-
construction AV survey. If this has not .een co, pleted, it should be ..nducted as
soon as possi. e. In addition, a reso- ce meeting ith agency pers. nel should be
established within hree months of th- post-construction urvey.
RK&K recommends at do, mentation be obtained •f agency agreement with
vegetative monitoring ant access criteria utilized for Man -• Bypass Bridge Mitigation
Site (NMFS criteria vs. c ' - is set forth in initial mitigatio• plan
NCDOT should co ' ue to mon' or and provide . 'nual monitori . reports of Ma- oes
Road Mitigation ' e, Manteo Bypa‘ Mitigation cite, Dismal Swam, Mitigation cite and
ite's Store tigation Site. The Co . has r-quested notification an. an o..ortunity to
atte•d annu•. monitoring activities. Re -•'al actions may be necessa .n the White's

Annual reports • the impac area associated with •e t-' porary work trestl- (CAMA

TIP No. K-4003
Dare County
Project Name: Roanoke Island Visitor Center
Project Description: Construction of the Roanoke Island Visitor Center and Rest Area
occurred in association with the newly constructed Manteo Bypass (R-2551) US 64/US
264 between the Croatan Sound and US 64/NC 345 intersection in Dare County.
Recommendations: NCDOT should continue to monitor both the Roanoke Island and
Mashoes Road Mitigation Sites for a five year period or until success criteria are met.
Hydrologic monitoring data for the Roanoke Island Mitigation Site should be clarified.
The report states that hydrology is jurisdictionally successful, although not all gauges are
meeting agency criteria for success as set forth in the mitigation plan. Gauge data
(RINT-2) should be revisited, as the data presented does not correspond with the
4

conclusion. It is recommended that NCDOT clarify hydrology data with respect to
reference gauges and, if necessary, revise hydrologic success criteria with agencies. It
appears from the hydrology data that the percentage of saturation/inundation in excess
of 20% may reflect elevations that are below those of the adjacent reference wetland.
As of April 29, 2002, DCM had no information on the status of the Roanoke Island
Mitigation Site. According to DCM records, some mitigation for K-4003 will be provided
through the Dismal Swamp Mitigation Bank. NCDOT should provide DCM with an
update on the progress of the Roanoke Island Mitigation Site and clarify any
discrepancies in the sources of compensatory mitigation. In addition, NCDOT should
continue to monitor the area of unauthorized clearing at the Roanoke Island Visitor
Center to ensure that vegetation is reestablishing.

Recomm- •dations: RK&K was unable to locate .* umentation that mitigation
requir-• ents have been fulfilled. NCDOT should ensure --t six credits have been
su. acted from the Scuppernong River Corridor Wetland Mitigation Bank for R-3838/R-
839 and that the appropriate documentation has been provided to and approved by
resource agencies (DCM, COE, DWQ).

Dear Mr. Harris:
Enclosed please find comments from the N.C. Division of Coastal Management (DCM) on the
following two documents submitted to DCM by the N.C. Department of Transportation
(NCDOT) on April 20, 2005 and August 15, 2005, respectively: "CAMA Permits with
Temporary Impact Monitoring Condition"; and"CAMA Permit Commitment Review." As you
know,in April 2002 DCM and NCDOT began a comprehensive effort to ensure that the
mitigation and monitoring conditions of the CAMA permits discussed in the attached documents
are satisfied.
DCM regrets that it took over a year to provide the attached comments. However, substantial
progress has been made during this period to achieve resolution on many of the projects
discussed in these documents. There are a total of 43 projects with CAMA permits discussed in
the attached documents: 20 projects have mitigation conditions only; 10 projects have temporary
impact monitoring conditions only; and 13 projects have both mitigation conditions and
temporary impact monitoring conditions. Based upon the attached analysis, DCM has
determined that the mitigation and/or temporary impact monitoring conditions of 17 projects
have been completely satisfied.
There are 23 CAMA permits discussed in the attached documents with mitigation and/or
monitoring conditions that remain unsatisfied. Compliance with some of these projects is
imminent or well underway. However, many of these projects have significant outstanding
unresolved issues, and are of particular concern to DCM. I do not believe that a general meeting
is necessary to discuss these projects. Instead, I hope that our staffs can put an emphasis on
working together to resolve the outstanding issues as detailed in the attached documents.

Approved mitigation sites for wetland impacts resulting from this project include: on-site restoration,
creation and preservation at the Roanoke Island Visitor Center/Rest Area Mitigation Site,North and
South tracts in Dare County and preservation at the Mashoes Road Mitigation Site in Dare County.
Unauthorized clearing of the preservation area at the Roanoke Island Visitor Center/Rest Area.
In a letter dated 3/6/02 from NCDOT to USACE,NCDOT provided information about unauthorized
mechanized clearing of 0.29 acres of wetlands within the preservation area of the Roanoke Island
Visitor Center Mitigation Site. Because preservation is only appropriate for"high quality" wetlands,
the cleared wetlands no longer qualified for preservation credits. Therefore,NCDOT requested that
the EEP provide mitigation for these 0.29 acres of wetland impacts elsewhere. In a letter dated
7/21/05, EEP stated it will compensate for these impacts by deducting 0.58 acres/credits from the
Scuppernong River Mitigation Bank's transferred balance from DOT. However, the Scuppernong
River Mitigation Bank is in Tyrrell County and the Tyrrell County 1996 land Use plan update on page
140 states that: "Tyrrell County opposes any 404 wetlands mitigation projects within Tyrrell County
undertaken to replace 404 wetlands outside of Tyrrell County." Furthermore, the impacts are in Dare
County, and the Dare County Land Use Plan 1994 Update on page 60 states that: "Mitigation
activities and improvements designed as compensation for wetland loss occurring in Dare County shall
be located, whenever possible, in Dare County and in proximity to the loss." Therefore, there is a
conflict with the local land use plans for the proposed debit from the Scuppernong River Wetland
Mitigation Bank. In an e-mail exchange during August 2006, DOT, DCM and EEP agreed that DOT
would request that EEP adjust the transferred balance for the Dismal Swamp Mitigation Site in Gates
County instead of the Scuppernong River Mitigation Bank in Tyrrell County for these impacts. Within
this request, DOT will need to demonstrate that there is not available mitigation in Dare County and in
proximity to the impact. When DCM receives a copy of the request from DOT to EEP,we will review
the proposal for consistency with the Gates County and Dare County CAMA land use plans. After the
DCM land use plan review is complete, and if it is favorable,then EEP will send out an
acknowledgement letter that the transferred asset beginning balances have been successfully adjusted.

Roanoke Island mitigation site. Mitigation is in the ground and monitoring is underway. DCM will
continue to coordinate with NCDOT to ensure that the mitigation requirements applied to the Roanoke
Island Mitigation Site are satisfied. A 1:1 ratio for creation was allowed due to the high probability of
success for extending adjacent wetland boundaries. If this area is struggling to achieve success,then
the ratio for creation may need to be increased to compensate for the time delay between incurring
impacts and accomplishing successful mitigation.
In a letter from DCM to NCDOT dated 4/22/04, DCM states: "DOT needs to add'a narrative to future
annual mitigation monitoring reports describing the unauthorized mechanized clearing of 0.29 acres of
wetlands within the preservation area of the Roanoke Island Visitor Center Mitigation Site, as
described in the letter from DOT to USACE dated 3/6/02. DOT should include a description of the
planting and monitoring for these unauthorized impacts as described in the 3/6/02 letter." The
NCDOT annual monitoring reports still do not appear to contain any specific reference to the planting
and monitoring of the area of unauthorized mechanized clearing at the Roanoke Island Visitor Center
Mitigation Site. NCDOT should include this information in the 2006, and subsequent, annual
monitoring reports for this site.
The revised Roanoke Island Visitor Information Center and Rest Area mitigation plan dated 7/17/02
requires NCDOT to re-vegetate 1,003.9 ft of riparian buffers along the stream located within the
project area for monitoring of riparian buffers. The mitigation plan states that: "Vegetation that is not
planted in wetland restoration or creation areas will be monitored pictorially and photos will be
provided at annual monitoring meetings." The NCDOT annual monitoring reports do not appear to
contain any specific data about the planting and monitoring of the riparian buffers at the Roanoke
Island Visitor Center Mitigation Site. NCDOT should include this information in the 2006, and
subsequent, annual monitoring reports for this site.
DCM needs to make a site visit to confirm compliance with condition number 3 of the CAMA permit
minor modification issued on 6/5/01 that states: "....The permittee must restore any wetlands, waters

0 0 A site visit with NCDOT and the appropriate resource agencies was held on April 23,2007 to discuss
6 p�T the continuing vegetation issues at the Visitor's Center. During this meeting, it was decided that DOT
/J would attempt to change the mitigation type from a BLH/Scrub Shrub to a marsh system. Please see
ce5( n5 .- the attached email to the agencies documentation this request to change mitigation type. Also,the 2006
annual monitoring report includes the buffer information as requested by DCM and has been posted on
NEU's website.NCDOT has sent an email to the EEP requesting they communicate with the DCM
concerning the transfer of assets. As per the EEP, it was decided by the regulatory agencies that the
NCDOT would replant the .29 acre site. The site has been replanted. The NCDCM should
communicate with the EEP as to monitoring and success of the restoration as per the agreement in the

NOTE: The Roanoke Island Visitor Center and Rest Area will permanently impact
approximately 1.15 acres of jurisdictional wetlands and approximately 145.5 linear feet
of jurisdictional stream. In addition, there will be approximately 0.01 acres of fill in
surface waters. The impacted wetlands are estuarine fringe wetland forest with dominant
vegetation including loblolly pine, red bay, wax myrtle, red maple, greenbrier and
American holly. Wetland impacts consist of approximately 0.82 acres of fill,
approximately 0.18 acres of isolated wetlands, and approximately 0.15 acres due to
mechanized clearing. These impacts and their associated approved mitigation as
described below is in addition to impacts and mitigation previously authorized by CAMA
Permit No. 7-98.
16) Approved mitigation sites for wetland impacts resulting from this project
include: on-site restoration, creation and preservation at the Roanoke Island
Visitor Center/Rest Area Mitigation Site, North and South tracts in Dare County
and preservation at the Mashoes Road Mitigation Site in Dare County.
17) On-site mitigation shall be conducted in accordance with the Roanoke Island
Visitor Center/Rest Area Mitigation Plan dated May 2001 except as altered
herein and except as altered by conditions of the modification to Water Quality
Certification No. 3167 (DWQ Project No. 000964) issued by the N.C. Division
of Water Quality(DWQ) on 5/29/01.
18) After environmental permits have been received for this project, the permittee
shall revise the Roanoke Island Visitor Center/Rest Area Mitigation Plan to
incorporate changes required by environmental permit conditions. The final
approved Roanoke Island Visitor Center/Rest Area Mitigation Plan shall be
distributed to DCM, DWQ, the U.S. Army Corps of Engineers (USACE) and the
N.C. Wildlife Resources Commission (WRC) prior to initiating construction on
any portion of this permitted project.
19) The Roanoke Island Visitor Center/Rest Area Mitigation Site shall be
constructed concurrent with construction of the Roanoke Island Visitor Center
and Rest Area, except for the vegetative planting which shall be completed
within one year after initiating construction on any portion of the Roanoke Island
Visitor Center and Rest Area.
20) Annual monitoring reports shall be provided to DCM and DWQ for five years for
the Roanoke Island Visitor Center/Rest Area Mitigation Site. Annual monitoring
reports shall include photos, hydrologic data from monitoring gauges, an
evaluation of that data, and an assessment of whether success criteria are being
met. Progress reports shall also be provided upon request. After five years,
monitoring may cease if the permittee can demonstrate that success criteria have
been met and written concurrence is received from DCM and DWQ. Failure to
meet success criteria will necessitate additional monitoring and/or remedial
actions.

3) In removing the spoil associated with the jetting operation, the permittee shall use
extreme care to ensure that the temporarily impacted areas are returned to pre-project
contours and elevations.
4) Due to the possibility that activities authorized under this permit modification might
prevent the temporary wetland impact area from re-attaining wetland jurisdictional
status, the permittee shall provide an annual update on the wetland areas temporarily
impacted by this project. This annual update will consist of photographs provided
during the agency monitoring report meeting and a brief report on the progress of
these temporarily impacted areas in re-attaining wetland jurisdictional status. Three
years after project completion, the permittee shall schedule an agency field meeting
with DCM, the NC Division of Water Quality and the NC Wildlife Resources
Commission to determine if the wetland areas temporarily impacted by this project
have re-attained jurisdictional wetland status. If at the end of 3 years the wetland
areas temporarily impacted by this project have not re-attained jurisdictional wetland
status, NC DOT and the above listed agencies shall determine whether a
compensatory wetland mitigation will be required.
USACE permit modification issued 5/11/00
Special condition 2) All fill material discharged into jurisdictional waters of the United
States, including wetlands will be removed in its entirety, with the surrounding
jurisdictional areas being restored to pre-construction contours to the satisfaction of the
appropriate COE representative.
Permit Conditions, minor modification issued 7/19/00.
1) "....This minor modification also authorizes delaying the planting schedule for the
Mashoes Road mitigation site from spring of 2000 to spring of 2001 to allow more time
to control Phragmites australis."
Minor modification issued 8/16/00
Authorizes the use of a large suction device to vacuum the marsh soil resulting from pile
jetting activities. This reduces the temporary impacts that need to be monitored per
condition 4 of the minor modification issued on 5/1/00 because the modification issued
on 5/1/00 authorizes removal of spoil material associated with jetting operations by using
a crane fitted with a clamshell bucket.
Permit conditions,minor modification issued 6/5/01, TIP No. K-4003, Roanoke
Island Visitor Center.
In a letter dated 2/17/06,DCM agreed with NCDOT's recommendation to discontinue
monitoring at the Mashoes Road Mitigation Site. Debits for K-4003 are: 1.36 acres
forest wetland preservation.
3) "....The permittee must restore any wetlands, waters or uplands that are impacted
within the 30-foot buffer by the work as described in Condition No. 2 of this permit to
their pre-project conditions."

NOTE: The wetland reforestation planting in wetland areas east of the new
Croatan Sound Bridge currently under construction as described in the
2/23/01 application letter for this project is hereby authorized.
On 3/6/02, DCM received a copy of a letter to David Franklin with information about
unauthorized mechanized clearing of 0.29 acres of wetlands within the preservation area
of the Roanoke Island Visitor Center Mitigation Site. The letter includes a mitigation
proposal for planting and monitoring. I did not see any specific reference to the planting
and monitoring of this area in the 2003 annual mitigation monitoring report. DCM never
responded to the 3/6/02 letter. However, Kelly Williams' suggestion to me at the time
was that these are temporary impacts that will take a long time to recover. She suggested
DOT be required to monitor the plantings for the entire monitoring period, and that they
not get any preservation credit for the area now that it is cleared since preservation credit
is usually reserved for areas of higher quality. Therefore,I recommend that DOT debit
additional preservation credits from the Mashoes Road Mitigation Site to compensate for
the 0.29 acres of preservation credits that are no longer available at the Roanoke Island

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for the Roanoke Island Visitor Center/ Rest Area; approximately 1.77 acres of
impacts are mitigated for onsite and the remaining 1.36 acres of preservation were
debited from the Mashoes Road Mitigation Site. The Roanoke Island Site was
constructed in 2002 and this report details the fourth year of hydrology monitoring and
first year (restart) of vegetation monitoring following construction.
Data from the fourth year of hydrologic monitoring indicates that ten of the eleven
monitoring gauges are meeting jurisdictional success by showing saturation within 12
inches of the surface for at least 12.5% of the growing season, and are within 20% of
the saturation period for their respective reference gauges. Non-reference Gauge
RINT-2 was saturated within 12 inches of the surface for 70.5% of the growing season.
This was well above 12.5% of the growing season, but not within 20% of the saturation
period for the reference gauge in that area.
As recommended last year, Gauge RIST-7 (ref) was moved to a more suitable location
on August 10, 2005, based on a more representative elevation with nearby Gauge
R I ST-8.
This site was replanted in March 2005 with containerized baldcypress and swamp
blackgum and bareroot Atlantic white cedar. Soil samples were taken on site. Soluble
salt levels are very high at this site, which is making it very difficult to get hardwood
vegetation to live. Compaction on site may also be an issue. In an attempt to get more
trees to survive, NCDOT is going to apply calcitic limestone, hand till the site, and
replant bareroot trees on 4-ft. centers.
NCDOT will continue to monitor vegetation and hydrology at the Roanoke Island
Mitigation Site.

2.0 HYDROLOGY
2.1 Success Criteria
While a constructed site must typically meet jurisdictional criteria of inundation or
saturation within 12 inches of the surface for at least 12.5% of the growing season,
NCDOT and consulting agencies agreed that other criteria might be the best indicator of
hydrologic success on this particular site. In accordance with the guidelines set forth by
the approved mitigation plans, hydrologic success is dictated by the hydrologic condition
of the reference wetlands adjacent to the sites. Monitoring gauges are located in both
the constructed and reference areas. The site is considered a hydrologic success if the
hydrologic frequency, duration and depth are within 20% of its respective reference
wetland.
The growing season in Dare County begins March 13 and ends November 25. The
dates correspond to a 50% probability that temperatures will drop to 28° F or lower after
March 13 and before November 25.1 The growing season is 258 days; therefore the
optimum duration for wetland hydrology is 32 days. While the monitoring gauges record
ground/surface water levels throughout the year, special attention is placed on water
levels during the 258-day growing season. In addition, local rainfall totals are monitored
to ensure that the site is functioning in normal climatic conditions.

2.3.2 Climatic Data
Figure 6 provides an evaluation of the local climate in comparison with historical data in
order to determine whether 2005 was "normal" in terms of climate conditions. The two
lines represent the 30th and 70th percentiles of monthly precipitation for Manteo, NC. The
bars are monthly rainfall totals for 2005. The historical data was collected from the State
Climate Office of North Carolina. The rainfall data for the Roanoke Island Site is
incomplete and can not be used to determine normalcy of rainfall. The rainfall data from
the Manteo Airport is incomplete for April and August and there was no data collected in
June or September. The onsite rain gauge malfunctioned during the beginning of the
growing season and the data collected through June is unreliable. The gauge was
replaced in June.
Due to the incomplete rainfall data both onsite and offsite only broad generalization can
be made for the rainfall in 2005. Based on the available data from the Manteo Airport, it
appears that the rainfall going in to the 2005 growing season (January through May)
was below normal, June was normal, and November was below normal. The on-site
rainfall data shows August, September, and November were below normal. There is a
discrepancy between the onsite and offsite data for July.
2.4 Conclusions
Data from the fourth year of hydrologic monitoring indicates that ten of the eleven
monitoring gauges are meeting jurisdictional success by showing saturation within 12
inches of the surface for at least 12.5% of the growing season, and are within 20% of
the saturation period for their respective reference gauges. Non-reference Gauge
RINT-2 was saturated within 12 inches of the surface for 70.5% of the growing season.
This was well above 12.5% of the growing season, but not within 20% of the saturation
period for the reference gauge in that area.
As recommended last year, Gauge RIST-7 (ref) was moved to a more suitable location
on August 10, 2005, based on a more representative elevation with nearby Gauge
RIST-8. Gauge RIST-7 (ref) was meeting success criteria for 2005 in its original
location and met success criteria for the remainder of the season in its new
location/elevation.
NCDOT recommends that hydrologic monitoring continue on the Roanoke Island
Mitigation Site.

Pluchea sp., Cladium sp., Phragmites sp., Pinus sp., and Baccharis halimifolia.
3.4 Conclusions
Approximately 1.77 acres of this site were planted as wetland restoration and creation
areas in March 2002. The site has been replanted in February 2004 and March 2005.
This site was replanted in March 2005 with containerized baldcypress and swamp
blackgum and bareroot Atlantic white cedar. The 2005 vegetation monitoring revealed
an average density of 210 trees per acre for year 1, which is below the 320 trees per
acre minimum requirement. Soil samples were taken on site. Soluble salt levels are very
high at this site which is making it very difficult to get hardwood vegetation to live.
Compaction on the site may also be an issue. In an attempt to get more trees to survive
NCDOT is going to apply calcitic limestone, hand till the site, and replant bareroot trees
on 4-foot centers.
4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
Data from the fourth year of hydrologic monitoring indicates that ten of the eleven
monitoring gauges are meeting jurisdictional success by showing saturation within 12
inches of the surface for at least 12.5% of the growing season, and are within 20% of
the saturation period for their respective reference gauges. Non-referece Gauge RINT-
2 was saturated within 12 inches of the surface for 70.5% of the growing season. This
was well above 12.5% of the growing season, but not within 20% of the saturation
period for the reference gauge in that area.
As recommended last year, Gauge RIST-7 (ref) was moved to a more suitable location
on August 10, 2005, based on a more representative elevation with nearby Gauge
RIST-8.
This site was replanted in March 2005 with containerized bald cypress, swamp
blackgum, and bareroot Atlantic white cedar. Soil samples were taken on site. Soluble
salt levels are very high at this site, which is making it very difficult to get hardwood
vegetation to live. Compaction on site may also be an issue. In an attempt to get more
trees to survive, NCDOT is going to apply calcitic limestone, hand-till the site, and
replant bareroot trees on 4-foot centers.
NCDOT will continue to monitor the Roanoke Island Mitigation Site for hydrology and
vegetation.

The purpose of this letter is to notify you that the Ecosystem Enhancement Program
(EEP) will adjust the transferred balance to the DOT Final Debit Ledger for the Scuppernong
River Mitigation Bank. The North Carolina Division of Coastal Management(NCDCM)Coastal
Area Management Act(CAMA) issued permits for the above referenced projects and required
mitigation to offset the impacts associated with the projects. The NCDCM required NCDOT to
debit the Scuppernong River Mitigation Bank 0.60 acres/credits for the Division 1 project(SR
1244, Tyrrell County),and 6.0 acres/credits for TIP Number R-3838/R-3839.
As a part of the U. S. Army Corps of Engineers' Individual Permit and NCDCM CAMA
permit,the NCDOT was required to mitigate for impacts associated with the construction of the
Roanoke Island Visitor's Center which was conducted on-site. During a site visit by NCDOT in
2002, it was noted that 0.29 acre of the non-riverine wetland preservation area was mistakenly
cleared. The USACE and NCDCM require non-riverine wetland mitigation to compensate for the
impacted wetland; therefore, EEP will further adjust the transferred balance of the Scuppernong
River Mitigation Bank for this impact utilizing a 2:1 ratio(0.58 acres/credits).
The adjustment to the Scuppernong River Mitigation Bank transferred balance is to
account for mitigation that was required by the USACE and NCDCM and requested by you in

letters dated June 23, 2005. Based on the final debit ledger received from DOT on January 28,
2004,the Scuppernong River Mitigation Bank contained 94.47 of non-riverine wetland

The purpose of this letter is to request that the North Carolina Ecosystem Enhancement
Program (EEP) provide compensatory mitigation for the above subject project. This
project, which is not listed in the MOA, is a project that we are requesting special
consideration of acceptance by the EEP. The site is currently under monitoring by
NCDOT.
The subject project located between the Croatan Sound and US 64/NC 345 intersection
was completed in March 2002. During construction, an area of forested wetland
preservation was inadvertently cleared. The Army Corps of Engineers (ACOE) and the
Division of Coastal Management(DCM) are requiring mitigation of 0.29 acre for impacts
to forested wetland preservation from construction of the project. To meet this past due
mitigation requirement,NCDOT is requesting EEP to provide mitigation for forested
wetland preservation to comply with the permit conditions.
The project is located in the Northern Outer Coastal Plain Physiographic Province in Dare
County in the Pasquotank River Basin in Hydrological Cataloguing Unit 03010205. The
forested wetland preservation impacts total 0.29 acre.

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for the Roanoke Island Visitor Center/ Rest Area; approximately 1.77 acres of
impacts are mitigated for onsite and the remaining 1.36 acres of preservation were
debited from the Mashoes Road Mitigation Site. The Roanoke Island Site was
constructed in 2002 and this report details the third year of hydrology monitoring and
first year of vegetation monitoring following construction.
Data from the third year of hydrologic monitoring indicates that nine of the eleven
monitoring gauges are meeting jurisdictional success by showing saturation within 12
inches of the surface for at least 12.5% of the growing season. Four gauges in the
constructed areas on the south tract are within 20% of the saturation period for three of
the four respective reference gauges (The saturation period is longer in the constructed
zone than at one of the four reference area gauges, which only met for 10.1% of the
growing season). The two gauges located in the north tract were not within 20% of the
saturation period for the reference gauge in that area. Gauge RIST-7 (ref) is at an
elevation 10" higher than RIST-8. Graph RIST-7 (ref) shows that this gauge meets
hydrology 100% of the growing season if this difference in elevation is adjusted.
NCDOT recommends moving RIST-7 (ref) to a more suitable reference elevation.
Due to low tree density during the 2003-monitoring year, the site was replanted in
February 2004. Vegetation monitoring yielded an average tree density of 238 trees per
acre for year 1, which is below the 320 trees per acre minimum requirement. The site
did not meet vegetation criteria for the 2004-year. NCDOT will replant the site in 2005
with containerized material, if available, in an attempt to increase survival rates.
NCDOT will continue to monitor vegetation and hydrology at the Roanoke Island
Mitigation Site.

1.0 INTRODUCTION
1.1 Project Description
The Roanoke Island Site serves as onsite mitigation for the Roanoke Island Visitor
Center/Rest Area, located adjacent to the new US 64-264 Manteo Bypass. The site is
divided into two tracts; the "south" tract is on the same property as the Visitor Center
and the "north" tract is located approximately 600 feet north of the Visitor Center (Figure
1). The mitigation is associated with Project 8.1052501, TIP Numbers K-4003 and R-
2551.
The site is designed to provide 0.11 acres of restoration (1:1) and 1.66 acres of creation
(1:1) of Estuarine Fringe wetlands. The site also includes 1.29 acres (5:1) of estuarine
preservation. In addition, approximately 1,004 feet of riparian buffer was planted with
the same vegetation mix as that used in the wetland zones. The width of the buffer
zone varies between 9 and 65 feet based on NCDOT property limits. The construction
plan for the wetland sites involved grading the former borrow pit areas to meet the
elevations of adjacent jurisdictional wetlands.
1.2 Purpose
In order to demonstrate successful mitigation, hydrologic and vegetative monitoring
must be conducted for a minimum of five years or until success criteria are fulfilled.
Success criteria are based on federal guidelines for wetland mitigation and are
stipulated in the "Roanoke Island Visitor Center/ Rest Area Mitigation Plan" dated May
2001 (revised July 2001). These guidelines stipulate criteria for both hydrologic
conditions and vegetation survival. The following report details the results of hydrologic
and vegetative monitoring during 2004 at the Roanoke Island Mitigation Site.
Activities in 2004 reflect the third year of hydrology monitoring and the first year of
vegetation monitoring at the mitigation site. Included in this report are analyses of both
hydrologic and vegetative monitoring results, as well as local climate conditions
throughout the growing season.

•
3.4 Conclusions
Approximately 1.8 acres of this site were planted in the wetland restoration and creation
areas in March 2002. The site was replanted in February 2004. The 2004 vegetation
monitoring revealed an average density of 238 trees per acre for year 1, which is below
the 320 trees per acre minimum requirement.
This site will be replanted in 2005. Containerized material will be used, if available, in
an attempt to increase survival rates.
4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
The 2004-year represents the third year of hydrologic monitoring and first year (restart)
of vegetation monitoring following construction. The hydrologic data indicates that nine
of the eleven monitoring gauges are meeting jurisdictional success by showing
saturation within 12 inches of the surface for at least 12.5% of the growing season. Four
gauges in the constructed areas on the south tract are within 20% of the saturation
period for three of the four respective reference gauges (The saturation period is longer
in the constructed zone than at one of the four reference area gauges, which only met
for 10.1% of the growing season). The two gauges located in the north tract were not
within 20% of the saturation period for the reference gauge in that area. Gauge RIST-7
(ref) is at an elevation 10" higher than RIST-8. Graph RIST-7 (ref) shows that this
gauge meets hydrology 100% of the growing season if this difference in elevation is
adjusted. NCDOT recommends moving RIST-7 (ref) to a more suitable reference
elevation.
Due to low tree density during the 2003-monitoring year, the site was replanted in
February 2004. Vegetation monitoring yielded an average tree density of 238 trees per
acre for year 1, which is below the 320 trees per acre minimum requirement. The site
did not meet vegetation criteria for the 2004-year. NCDOT will replant the site in 2005
with containerized material, if available, in an attempt to increase survival rates.
NCDOT will continue to monitor the Roanoke Island Mitigation Site for hydrology and
vegetation.

Wetland Specialist Notes
Plots 2 and 4 are doing very poorly. Plot 1 is not meeting success criteria. I agree that the site should be replanted,
but I wonder if the hydrology of the site is appropriate for the species planted. The plot with the most survival(P3)is
located near a gauge that shows alternation between an innundated and saturated state. Only one of the reference
gauges is innundated for an extended period of time. Is it possible that the restoration area is too wet for the target
species? What species are present in the reference wetlands?

DOT Project Coordinator Notes
Provides mitigation for K-4003(Modification to CAMA Permit No.7-98 issued on 6/5/01).
I agree with DOT's proposal to replant the site and continue vegetation and hydrologic monitoring.
DOT needs to add a narrative to future annual mitigation monitoring reports describing the unauthorized mechanized
clearing of 0.29 acres of wetlands within the preservation area of the Roanoke Island Visitor Center Mitigation Site,as
described in the letter from DOT to USACE dated 3/6/02. DOT should include a description of the planting and
monitoring for these unauthorized impacts as described in the 3/6/02 letter. DCM does not believe that DOT should
receive preservation credit for the area now that it is cleared since preservation credit is usually reserved for areas of
higher quality. Therefore,DOT should debit additional preservation credits from the Mashoes Road Mitigation Site to
compensate for the 0.29 acres of preservation credits that are no longer available at the Roanoke Island Visitor Center
Mitigation Site.

Final Comments
DCM agrees that the site should be replanted due to low survival in half of the plots. DCM staff note that the plot with
the highest plant survival(P3)is located near a gauge that alternates between an inundated and saturated state. In
addition,only one of the reference gauges is inundated for an extended period of time. Is it possible that the
restoration area is actually too wet for some of the target species? How does the species composition of the reference
wetland compare to the target community for the restoration site?

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Roanoke Island Mitigation Site. The site was constructed to serve as
mitigation for the Roanoke Island Visitor Center/ Rest Area; approximately 1.77 acres of
impacts are mitigated for onsite and the remaining 1.36 acres of preservation were
debited from the Mashoes Road Mitigation Site. The Roanoke Island Site was
constructed in 2002 and this report details the second year of monitoring activities
following construction.
Data from the second year of hydrologic monitoring indicates that the site is, at
minimum, meeting jurisdictional success by showing saturation within 12 inches of the
surface for at least 12.5% of the growing season. However, the gauges in the
constructed areas on the south tract are within 20% of the saturation period for only half
of their respective reference gauges. The saturation period is longer in the constructed
zone (not less than 87% of the growing season) than at two of the four reference area
gauges. Both of the gauges on the north tract are within 20% of the saturation period for
the reference gauge in that area.
Vegetation monitoring yielded only 168 trees per acre, which is below the minimum
requirement (320 trees per acre for three years). NCDOT will replant the site and
continue to monitor for vegetation in 2004.
NCDOT will continue to monitor vegetation and hydrology at the Roanoke Island
Mitigation Site.

2.0 HYDROLOGY
2.1 Success Criteria
While a constructed site must typically meet jurisdictional criteria of inundation or
saturation within 12 inches of the surface for at least 12.5% of the growing season,
NCDOT and consulting agencies agreed that other criteria may be the best indicator of
hydrologic success on this particular site. In accordance with the guidelines set forth by
the approved mitigation plans, hydrologic success is dictated by the hydrologic condition
of the reference wetlands adjacent to the sites. Monitoring gauges are located in both
the constructed and reference areas. The site is considered a hydrologic success if the
hydrologic frequency, duration and depth are within 20% of its respective reference
wetland.
The growing season in Dare County begins March 13 and ends November 25. The
dates correspond to a 50% probability that temperatures will drop to 28° F or lower after
March 13 and before November 25.1 The growing season is 258 days; therefore the
optimum duration for wetland hydrology is 32 days. While the monitoring gauges record
ground/surface water levels throughout the year, special attention is placed on water
levels during the 258-day growing season. In addition, local rainfall totals are monitored
to ensure that the site is functioning in normal climatic conditions.
2.2 Hydrologic Description
The site was constructed by grading existing fill material down to meet the elevations of
the existing reference wetlands. The removed fill material is associated with borrow pit/
spoil basins that were previously onsite. Eleven monitoring gauges were installed on the
site in order to monitor the new hydrologic conditions. Three gauges are located on the
north tract and eight gauges are located on the south tract. Of these, one gauge is
located within the north tract reference wetland, while four gauges are located within
reference areas in the south tract. The success of the site is determined by comparing
the groundwater levels in the reference areas with those in the constructed zones.
Site rainfall is monitored with a rainfall gauge located onsite. In addition, the recorded
data is compared to rainfall data at the Manteo Airport gauge in order to check the
accuracy of the measured data. The Manteo data was provided by the NC State
Climate Office. Figures 2 and 3 are monitoring gauge maps of the north and south
tracts, respectively.

2.3.2 Climatic Data
Figure 6 represents an evaluation of the local climate in comparison with historical data
in order to determine whether 2003 was "average" in terms of climate conditions. The
two lines represent the 30th and 70th percentiles of monthly precipitation for Manteo, NC.
The bars are monthly rainfall totals for 2002 and 2003. The onsite rain gauge at
Roanoke Island was used for the 30-70 percentile graph for the months of September-
November. The historical data was collected from the State Climate Office of North
Carolina.
For the 2003-year, January and November experienced below average rainfall. The
months of December (02'), March, June, August, and October all recorded average
rainfall for the site. November (02'), February, April, May, July, and September
experienced above average rainfall. The rainfall data from the onsite rain gauge was
used for the months of September-November. Overall, 2003 experienced an average to
above average rainfall year.
2.4 Conclusions
The 2003-year represents the second complete year of monitoring for the Roanoke
Island Mitigation Site. The hydrologic data indicates that the site is, at minimum,
meeting jurisdictional success by showing saturation within 12 inches of the surface for
at least 12.5%0 of the growing season. However, the gauges in the constructed areas
on the south tract are within 20% of the saturation period for only half of their respective
reference gauges. The saturation period is longer in the constructed zone (not less than
87% of the growing season) than at two of the four reference area gauges. Both of the
gauges on the north tract are within 20% of the saturation period for the reference
gauge in that area.
NCDOT recommends that hydrologic monitoring continue on the Roanoke Island
Mitigation Site.

3.4 Conclusions
Approximately 1.8 acres of this site (wetland restoration and creation areas) were
planted in March 2002. The 2003 vegetation monitoring revealed an average density of
168 trees per acre, which is below the 320 trees per acre minimum requirement.
NCDOT will replant the site and continue vegetation monitoring at the Roanoke Island
Mitigation Site.
4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
The 2003-year represents the second year of hydrologic and vegetation monitoring
following construction. The hydrologic data indicates that the site is, at minimum,
meeting jurisdictional success by showing saturation within 12 inches of the surface for
at least 12.5% of the growing season. However, the gauges in the constructed areas on
the south tract are within 20% of the saturation period for only half of their respective
reference gauges. The saturation period is longer in the constructed zone (not less than
87% of the growing season) than at two of the four reference area gauges. Both of the
gauges on the north tract are within 20% of the saturation period for the reference
gauge in that area.
Vegetation monitoring yielded an average tree density of 168 trees per acre over the
four plots. The site did not meet vegetation criteria for the 2003-year. NCDOT will
replant the site and continue to monitor vegetation success.
NCDOT will continue to monitor the Roanoke Island Mitigation Site for hydrology and
vegetation.

K-4003 CAMA Permit No. 7-98
Executive Summary
NCDOT developed the Roanoke Island Visitor Center and Rest Area (T.I.P.
Project No. K-4003) in association with the newly constructed Manteo Bypass (R-2551)
US 64/US 264 between the Croatan Sound and US 64/NC 345 intersection in Dare
County. Total impacts from the project included 1.15 ac of jurisdictional wetlands, 145.5
linear feet of stream and 0.01 ac of fill in surface waters. In correspondence dated
March 6, 2002, NCDOT notified the COE of the unauthorized clearing of 0.29 ac of
wetlands at the Roanoke Island Visitor Center Mitigation Site. NCDOT agreed to replant
and monitor the cleared preservation area and notify the affected property owner of the
encroachment. DCM detailed the mitigation commitments associated with K-4003 in a
minor modification of Permit No. 7-98. NCDOT constructed the Roanoke Island Visitor
Center Mitigation Site to provide compensatory mitigation for this project with remaining
credits coming from Mashoes Road Mitigation Site. The Roanoke Island and Mashoes
Road Mitigation Sites have completed their first year of monitoring. NCDOT should
continue monitoring mitigation sites for a five year period and clarify hydrology success
for the Roanoke Island Mitigation Site. NCDOT should provide DCM with an update on
the progress of the Roanoke Island Mitigation Site and clarify any discrepancies in the
sources of compensatory mitigation for K-4003. In addition, NCDOT should continue to
monitor the area of unauthorized clearing at the Roanoke Island Visitor Center to ensure
that vegetation is reestablishing.
Project Description
NCDOT developed the Roanoke Island Visitor Center and Rest Area (K-4003) in
association with the newly constructed Manteo Bypass (R-2551) US 64/US 264 between
the Croatan Sound and US 64/NC 345 intersection in Dare County. Total impacts
resulting from the project include 1.15 ac of jurisdictional wetlands (0.82 ac of fill, 0.18 ac
of isolated wetlands, 0.15 ac mechanized clearing), 145.5 linear feet of jurisdictional
stream and 0.01 ac of fill in surface waters. According to the Roanoke Island Visitor
Center Mitigation Plan, NCDOT provided compensatory mitigation through on-site
restoration and creation of 1.77 ac of wetlands and preservation of 1.29 ac of estuarine
fringe wetlands located at the Visitor Center and preservation of 1.36 ac of forested
wetlands at the Mashoes Mitigation Site. In addition, compensatory mitigation for
Waters of the United States classified, as "SA" waters will be provided through 1,003.9
feet of riparian buffer mitigation at the Roanoke Island Visitor Center. Authorization for
this project falls under CAMA Permit No. 7-98, the same Permit No. issued for R-2551.
Project Timeline
• January 20, 1998: CAMA Permit No. 7-98 issued.
• March 2002: Construction of Roanoke Island Mitigation Site completed.
• March 6, 2002: Unauthorized clearing of wetlands at the Roanoke Island Visitor
Center Mitigation Site documented.

Permit Commitments
CAMA Permit No. 7-98 minor modification
1) This modification authorizes the construction of the Roanoke Island Visitor
Information Center and Rest Area adjacent to US 64-264 between the Croatan
Sound and the US 64/NC 345 intersection as depicted on the attached workplan
drawings.
2) No development or land disturbing activity shall take place within 30 feet of the
mean high water line except that the permittee may remove portions of the existing
fill material that falls within the 30-foot buffer and replace it with new fill material to
create a more stable fill slope as depicted on the attached workplan drawings. The
permittee must minimize as much as possible the need to place any new fill material
within the 30-foot buffer, even if the new fill material remains within the footprint of
the existing material.
3) Staging areas within the 30-foot buffer required to conduct the work as described
in Condition No. 2 of this permit must be the minimum necessary, and must be
restricted to previously disturbed areas within the 30-foot buffer. The permittee must
restore any wetlands, waters or uplands that are impacted within the 30-foot buffer
by the work as described in Condition No. 2 of this permit to their pre-project
conditions.
16) Approved mitigation sites for wetland impacts resulting from this project include:
on-site restoration, creation and preservation at the Roanoke Island Visitor
Center/Rest Area Mitigation Site, North and South tracts in Dare County.
17) On-site mitigation shall be conducted in accordance with the Roanoke Island
Visitor Center/Rest Area Mitigation Plan dated May 2001 except as altered herein.
18) After environmental permits have been received for this project, the permittee
shall revise the Roanoke Island Visitor Center/Rest Area Mitigation Plan if necessary
to incorporate changes required by environmental permit conditions. The final
approved Roanoke Island Visitor Center/Rest Area Mitigation Plan shall be
distributed to DCM, DWQ, the COE and WRC prior to initiating construction on any
portion of this permitted project.
19) The Roanoke Island Visitor Center/Rest Area Mitigation Site shall be
constructed concurrent with construction of the Roanoke Island Visitor Center/Rest
Area, except for the vegetative planting which shall be completed within one year
after initiating construction on any portion of the Roanoke Island Visitor Center/Rest
Area.
20) Annual monitoring reports shall be provided to DCM and DWQ for five years for
the Roanoke Island Visitor Center/Rest Area Mitigation Site. Annual monitoring
reports shall include photos, hydrologic data from monitoring gauges, an evaluation
of that data, and an assessment of whether success criteria are being met. Progress
reports shall also be provided upon request. After five years, monitoring may cease
if the permittee can demonstrate that success criteria have been met and written
2

concurrence is received from DCM and DWQ. Failure to meet success criteria will
necessitate additional monitoring and/or remedial actions.
24) The NC DWQ has authorized the proposed project under General Water Quality
Certification No. 3274 (DWQ Project No. 00-0951), which was issued on 9/6/00
(need information from DWQ). Any violation of the Water Quality Certification issued
by DWQ will be considered a violation of this CAMA permit.
NOTE: The wetland reforestation planting in wetland areas east of the new Croatan
Sound Bridge currently under construction as described in the 2/23/01 application
letter for this project is hereby authorized.
Mitigation Status
NCDOT completed construction of the Roanoke Island Mitigation Site in March
2002 and has completed the first year of monitoring. This site serves solely as
mitigation for the Roanoke Island Visitor Center/Rest Area. As stated in the first year
(2002) monitoring report, hydrologic success criteria agreed upon by NCDOT and
agency personnel require that hydrology be within 20% in frequency, duration, and depth
of the associated reference wetland. The 2002 monitoring report states that the two
gauges located on the north tract are within 20% of the reference gauge. According to
the data listed, however, the percent consecutive days saturated (36.05%) for one of the
gauges (RINT-2) is not within 20% of the reference gauge (53.49%). On the south tract,
two of the four monitoring gauges met success criteria. All of the monitoring gauges
indicated saturation or inundation for much longer periods than did the corresponding
gauges located in reference wetlands. Vegetation success criteria require a minimum of
320 trees per acre at the end of three monitoring years. Results from four vegetative
plots located on the north and south tract indicate vegetation exceeds success criteria
with an average tree density of 404 trees per acre. Five years of monitoring are required
for this site.
NCDOT completed construction of the Mashoes Road Mitigation Site in 1999.
Planting of trees along the west side of the site occurred in 1999 and again in 2000-
2001. Planting of marsh grass occurred in spring of 2001. The 2002 monitoring report
represents the second year of monitoring. NCDOT performed Phragmites treatment in
October 2000, April 2001 and again in November 2002. Success criteria for the west
side of the site required saturation or inundation within 12 inches of the surface for at
least 12.5% of the growing season. All nine groundwater gauges met this criteria. On
the eastern (coastal marsh) side of the site, success requires saturation or inundation for
at least 25% of the growing season or statistically equivalent to the reference site. All ten
surface gauges met the 25% criteria measured in consecutive as well as cumulative
days. Vegetation on the west side of the sight is exceeding required success criteria
with 639 trees per acre; 320 trees are required for third year monitoring. The east side
of the site is not yet meeting success criteria with 54.0% of the plots containing the
target species (70% required) and a scale value of 3.92 for vegetative coverage (value
of 5 required at year 5). Five years of monitoring are required. The Mashoes Road
Mitigation Site 2002 monitoring report (second year) documents 1.36 ac of forested
wetland preservation debited for K-4003.
In correspondence dated March 6, 2002, NCDOT notified the COE of the
unauthorized clearing of 0.29 ac of wetlands (0.06 ac outside of NCDOT right-of-way
3

and 0.13 ac within the designated preservation area) at the Roanoke Island Visitor
Center Mitigation Site. NCDOT agreed to replant and monitor the cleared preservation
area and notify the affected property owner of the encroachment.
Recommendations
NCDOT should continue to monitor both the Roanoke Island and Mashoes Road
Mitigation Sites for a five year period or until success criteria are met. Hydrologic
monitoring data for the Roanoke Island Mitigation Site should be clarified. The report
states that hydrology is jurisdictionally successful, although not all gauges are meeting
agency criteria for success as set forth in the mitigation plan. Gauge data (RINT-2)
should be revisited, as the data presented does not correspond with the conclusion. It is
recommended that NCDOT clarify hydrology data with respect to reference gauges and,
if necessary, revise hydrologic success criteria with agencies. It appears from the
hydrology data that the percentage of saturation/inundation in excess of 20% may reflect
elevations that are below those of the adjacent reference wetland.
As of April 29, 2002, DCM had no information on the status of the Roanoke
Island Mitigation Site. According to DCM records, some mitigation for K-4003 will be
provided through the Dismal Swamp Mitigation Bank. NCDOT should provide DCM with
an update on the progress of the Roanoke Island Mitigation Site and clarify any
discrepancies in the sources of compensatory mitigation. In addition, NCDOT should
continue to monitor the area of unauthorized clearing at the Roanoke Island Visitor
Center to ensure that vegetation is reestablishing.

Note:
This mitigation plan replaces the previous mitigation plans for this project.
• 1.0 Introduction
The North Carolina 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-2551 between the Croatan Sound and the US 64/NC
345 intersection in Dare County. The proposed right-of-way will be approximately 9.2 ac.
1.1 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 1.15 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 clearing. 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 the 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 (1:1) and creation of 1.66 ac. (1:1) by removal of the
portions of the associated fill from the borrow pit that was once onsite and vegetating with
species matching the target 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 ac. (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 Dare 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 various 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 earlier, 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 located 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)
South Tract
The existing site is approximately 9.2 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 1.5 feet above mean sea level (msl) to 5.0 feet above msl.
The wetland area east of the borrow pit is characterized as an estuarine 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(Smilax
sp.), and American holly (Rex 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 borrow pit. Baymeade fine sand, Leon fine sand. and
Belhaven muck are 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. This stream has been channelized and riparian 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 1.5 feet above mean sea level (msl) to 4.0 feet above msl.
A portion of the remaining borrow pit/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 Dare 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 marsh
community. Dominant vegetation present in the estuarine fringe community includes silverling
(Baccharis halimifolia) loblolly pine (Pinus taeda). red bay (Persea borbonia), wax myrtle
(Myrica cerifera). red maple (Acer rubrum), greenbrier(Smilax sp.), American holly (Ilex
opaca). and sweet gum (Liquidambar stvraciflua). Dominant vegetation present in the tidal
marsh community includes black needlerush (Juncus roemerianus), saltmeadow cordgrass
(Spartina patens), and cattails (Typha angustifolia)
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 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 target 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.

2.3 Monitoring
South Tract
Hydrologic monitoring will occur throughout the growing season in the wetland areas by using
40-inch groundwater gauges. Two groundwater gauges will 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 Estuarine Fringe community as reference
gauges. Hydrologic success criteria will be based on the establishment of hydrologic conditions
similar in frequency, duration and depth to those documented in the existing reference wetlands
adjacent to the areas being restored. Similar hydrologic frequency, duration and depth shall be
determined as being within 20% of the respective reference wetlands established on the eastern
and western side of the Roanoke Island Visitor Center and Rest Area.
Vegetation monitoring will consist of two plot(s) for the Estuarine 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 year three with a target survival of 260
stems per year in year 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 areas by using
40-inch groundwater gauges. Two groundwater gauges will be placed in the creation Estuarine
Fringe area. One groundwater gauge will be placed in the existing Estuarine Fringe community
as a reference gauge. Hydrologic success criteria will be based on the establishment of
hydrologic conditions similar in frequency, duration and depth to those documented in the
existing reference wetlands adjacent to the areas being restored. Similar 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 Estuarine 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 year three with a target 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 will 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

David,
Cathy Brittingham asked me to update you on the Roanoke Island
Visitor Center. Yesterday (5-10-01) , Leilani Paugh and I visited
the site and looked at the potential for re-vegetation along the
streambanks onsite, adding to what we had committed to in our
last meeting with resource agencies. We plan to modify our
mitigation plan to include the re-vegetation of 948 ft linear of
stream buffers within DOT right-of-way. This quantity will
provide more than the amount requested by the EPA [145 ft of
impacts at 5:1 ratio (stabilization) ] . We also looked at the 1.0
ac DOT property which is now part of an old borrow site on the
opposite side of the new US 64-264 corridor for
creation/restoration potential. We plan to grade this area to an
adjacent reference elevation and plant with the wetland
vegetation mix as proposed in our original mitigation plan and
possibly other wetland species pending resource agency approval.
From what Cathy has told me, DCM and DWQ both plan to permit the
project with the original mitigation plan, then do a modification
once we provide a revised plan (basically adding additional
stream buffer vegetation and getting all mitigation onsite
instead of debiting NCDOT Mashoes Rd. and NCDOT Dismal Swamp
sites.
Please contact Cathy with your comments as soon as possible. If
we have permits in hand by May 15, we can still make the June
let. I think this is still possible, assuming there are no last
minute problems. Thank you for your assistance and please feel
free to contact me if you have any questions.

Cathy,
I received a phone call from Chris Rivenbark regarding the Roanoke
Island Visitiors Center. He wanted me to pass on that the DOT was
looking into additional mitigation aspects for the project, and he went
to a site yesterday that he feels is a reasonable alternative. He said
that the DOT would be proposing/conducting mitigation for wetlands at
the new site, and undetake stream enhancement/mitigation at the project
site. He also asked that I pass on to you that the wetland mitigation
would be similar to what Dare County proposed for mitigation for the
Dare County Justice Facility, and that the DOT would be trying to
basically extend what the County is going to do at the Justice Facility
mitigation site. If you have any questions, you can call Chris at
733-9513 .

Hello All,
In response to John's e-mail below that states DCM has some concerns about the proposed mitigation for
K-4003. That was true. However, Chris Rivenbark met with Kelly Williams and me this afternoon to
respond to DCM's concerns. DCM now approves of the mitigation plan as proposed with one exception:
DCM is requesting a change to the proposed hydrologic success criteria. We would like the hydrologic
success criteria to be based on reference wetlands. Mike and John -I will send you a more detailed e-mail
tomorrow with proposed language for the success criteria for your review and comment. DOT was
agreable to this proposed change.

Bill,
To my knowledge(which is almost always limited by genetics and training)there are two primary issues.
Issue 1: The Corps is doing a Public Notice for this project. We have not received it, yet (sorry Mike if
this causes you problems).
Issue 2: I don't speak for DCM. However,I think they have some concerns about the proposed
mitigation. Based on what I understand their concerns to be, I agree that they have merit.
Once the two issues above are dealt with, I think we will be ready to issue the 401 WQC. Sorry for any
inconvenience this may cause.
Let me know if I can be of further assistance.

I have been informed that the access issue at the rest area has been resolved and that Chris Rivenbark
is forwarding the information about the closure to Mike. Since this is a hot project,please provide me
with your best estimate as to when we will have your applications processed. This is a high priority
for us. Our cutoff dates are May 29 and July 3. I believe that the access issue resolution has completed
all outstanding issues. Thanks.
