RE: Mashoes Road Wetland Mitigation Site, Dare County, Coastal Area Management Act
(CAMA)Permit No. 7-98, TIP No. R-2551 and TIP No. K-4003.
Dear Mr. Harris:
This letter is in response to your correspondence dated 6/13/05 to the N.C. Division of Coastal
Management(DCM)regarding the regulatory release of the Mashoes Road Wetland Mitigation Site
in Dare County. This 399-acre site provides coastal marsh restoration and preservation, forested
wetlands restoration and preservation, open water, and forested upland hummocks. The site is
designed to mitigate for impacts incurred by the improvements to US 64/264 in Dare County from
US 264 in the Alligator River National Wildlife Refuge to NC 345 south of Manteo, including new
bridges across Spencer Creek and the Croatan Sound (TIP No. R-2551, CAMA Permit No. 7-98)
and the Roanoke Island Visitor Information Center and Rest Area(TIP No. K-4003, modification to
CAMA Permit No. 7-98).
The mitigation plan states that: "This species [Phragmites australis] will be excluded from the
coastal marsh restoration area Phragmites will also be totally controlled on the coastal marsh
site following construction." In a letter to the N.C. Department of Transportation (NCDOT) dated
5/2/05, DCM expressed our concern that 108 of the 160 vegetation plots monitored in 2004
contained Phragmites australis. This letter also informed NCDOT that DCM does not allow
CAMA Coastal Wetland mitigation credit for areas dominated by Phragmites.
On 8/9/05, DCM staff attended an interagency site visit with NCDOT to the Mashoes Road
Wetland Mitigation Site. The following other state and federal agencies were also represented: the
U.S. Army Corps of Engineers (USACE),Ecosystem Enhancement Program (EEP), NCDOT,
Wildlife Resources Commission (WRC), U.S. Fish and Wildlife Service (USFWS),Environmental
Protection Agency(EPA) and N.C. Division of Water Quality(DWQ). The site visit attendees
agreed that the site has met its goals and success criteria, except for the fact that it is dominated by
Phragmites. All of the agencies agreed that NCDOT has done everything reasonable to control the
Phragmites. However, DCM did not agree that a site dominated by Phragmites can be considered
acceptable mitigation for CAMA Coastal Wetland impacts.

In a letter dated 10/27/05, USFWS provided a statement of management intent for the Mashoes
Road Wetland Mitigation Site. Specifically, the USFWS 10/27/05 letter states that: "Land and
waters of the Mashoes Road Mitigation Site, upon transfer to the U.S. Fish and Wildlife Service,
will be integrated into the overall refuge lands system as part of the Alligator River National
Wildlife Refuge. These lands will be subject to management actions that will provide the highest
quality natural wildlife habitat possible...."
Based upon the statement of management intent contained within the 10/27/05 USFWS letter, DCM
will agree with NCDOT's recommendation to discontinue monitoring at this site. While DCM does
not typically accept coastal marsh dominated by Phragmites as mitigation for CAMA Coastal
Wetland impacts, this site is being considered as a special exception due to the USFWS'
. demonstrated interest in acquiring the site, their dedication to long-term management of the site,
including control of Phragmites, and their success in controlling Phragmites in similar adjacent
areas.
DCM cautions NCDOT that the decision to agree with the recommendation to discontinue
monitoring at this site should not be interpreted as a change from our position that a mitigation site
that is dominated by Phragmites is not suitable mitigation for impacts to CAMA Coastal Wetlands.
DCM is only agreeing with NCDOT's recommendation to discontinue monitoring at this site due to
the statement of management intent contained within the 10/27/05 USFWS letter, and our belief that
this will ensure that the site provides high quality coastal marsh habitat in the long-term.
Please contact Cathy Brittingham at(919) 733-2293 x238 or via e-mail at
[e-mail] is you have any questions or concerns.

Dear Dr. Thorpe:
Reference the Department of the Army (DA)permit issued to you on March 5, 1998,
associated with the widening of approximately 10 miles of U.S. Highway 64-264, including
constructing a new bridge over the Croatan Sound and adjacent marshes, from US Highway 64-
264 west of Manns Harbor to NC 345 south of Manteo, in Dare County,North Carolina(TIP No.
R-2552, Federal Aid Project No.NHF-64(6), State Project No. 8.T051401). Also reference your
subsequent written request dated March 23, 2006, for a permit modification to modify the
requirements of special condition e. in the USACE permit to you described above.
The original special condition (e) required that mitigation work for marsh and non-
riverine bottomland hardwood wetlands be undertaken at the Mashoes Road mitigation site
pursuant to the plan entitled"Mitigation Plan,Mashoes Road Mitigation Site." The Mashoes
Road mitigation plan had previously stated that a 0% tolerance for Phragmites australis would
be allowed in the coastal marsh site following construction. As indicated in the yearly
monitoring reports,Phragmites has been treated at the site yearly and NCDOT has made every
effort possible to control the spread of Phragmites throughout the site. Your modification
request proposes that we eliminate the 0%tolerance requirement for Phragmites.
In association with this proposal, the land and waters of the Mashoes Road Mitigation
Site will be transferred to the U.S. Fish and Wildlife Service (FWS) as part of the project
mitigation plan and will be integrated into the overall refuge lands system as part of the Alligator
River National Wildlife Refuge. These lands will be subject to management actions that will
provide the highest quality natural wildlife habitat possible. Management actions which will be
used by the FWS include,but are not restricted to,use of prescribed fire to mimic natural fire
regimes and control of invasive and exotic species such as Phragmites. The FWS will see that
the lands of the Mashoes Road Mitigation Site will be maintained and managed under the
mission and purpose statement of the National Wildlife Refuge System.

The mission of the National Wildlife Refuge System is to administer a national network of lands
and waters for the conservation, management, and where appropriate, restoration of the fish,
wildlife, and plant resources and their habitats within the United States for the benefit of present
and future generations of Americans.
On August 9, 2005, an interagency site visit to the Mashoes Road Mitigation Site was
attended by staff from the U.S. Army Corps of Engineers (USACE), North Carolina Department
of Transportation(NCDOT),North Carolina Division of Coastal Management(CAMA),
Ecosystem Enhancement Program (EEP),North Carolina Wildlife Resources Commission
(WRC), U.S. Fish and Wildlife Service (FWS), Environmental Protection Agency(EPA), and
the North Carolina Division of Water Quality(DWQ). At that time, all the agencies except for
DCM were in agreement that the mitigation site had met its goals and success criteria and that
the site could be considered closed and that no further monitoring shall be required. DCM by
letter dated February 17, 2006 agreed that based on the FWS statement of management intent for
the site that upon transfer to the FWS the area would no longer need to be monitored and they
would except the mitigation as a special exception due to the FWS demonstrated interest in
acquiring the site, including control of Phragmites, and their success in controlling Phragmites
in similar adjacent areas.
This modification request was coordinated with the appropriate State and Federal
agencies and the coordination revealed no objections to this modification request. Therefore,
special condition (e) of the referenced permit shall remain in full force and effect with the
exception that references to the control of Phragmites australis shall be replaced with the
following language:
-As of the date of this permit modification, The NC Department of Transportation is no
longer responsible for the control of Phragmites australis on the Mashoes Road mitigation site.
It is understood that all conditions of the original permit remain applicable and that the
expiration date is unchanged. In addition,by copy of this letter, we are notifying you that no
further monitoring of the site will be required.
Any questions regarding this correspondence may be directed to Mr. Bill Biddlecome,
NCDOT Coordinator/Regulatory Project Manager at the Washington Regulatory Field Office,

Subject: Permit Modification; US 64/264 Bridge over Croatan Sound, Dare
County; TIP No. R-2551 &K-4003; State Project No. 8.T051401;Action
ID 199502334; DWQ Project Nos. 970856 & 000964; DCM Permit No. 7-
98.
The U. S. Army Corps of Engineers (USACE) issued a Section 404 Individual
Permit (IP) on March 4, 1998 for the construction of the subject projects. The special
conditions of the IP required the North Carolina Department of Transportation to
compensate for a portion of the unavoidable wetland impacts by providing the following:
restore 8.0 ac. of previously affected palustrine forested wetlands, preserve 76.20 ac. of
palustrine forested wetlands, restore 13.10 ac. of previously affected estuarine marsh
wetlands, and preserve 122.90 acres of estuarine marsh wetlands at the Mashoes Road
mitigation site in Dare County.
As you are aware, the Department constructed the mitigation site in the Spring of
1999 and planting was completed in Spring of 2001. Currently, the site has completed
the fourth year of post-construction monitoring.
As was documented in the 2004 Annual Monitoring Report and discussed at the
2004 Mitigation Monitoring Report Meeting on May 5, 2005,NCDOT has proposed to
closeout the Mashoes Road mitigation site. During the monitoring report meeting, the
N.C. Division of Coastal Management(NCDCM) expresseira concern fiiat-10$ofT60
marsh vegetation plots monitored in 2004 contained Phragmites australis. According to
Special Condition e. in the original permit dated March 4, 1998, mitigation work for
marsh and non-riverine bottomland hardwood wetlands will be undertaken at the
Mashoes Road mitigation site pursuant to the plan entitled"Mitigation Plan, Mashoes

Road Mitigation Site". The Mashoes Road mitigation plan had previously stated that a
0%tolerance for Phragmites would be allowed in the coastal marsh site following
construction. As indicated in the monitoring report,Phragmites has been treated at the
site yearly. NCDOT has made every effort possible to control the spread of Phragmites
throughout the site. The Department requests that the USACE modify the permit to allow
Phragmites australis at the Mashoes Road mitigation site. NCDOT also requests that the
USACE consider the Mashoes Road mitigation to be closed and that no further
monitoring shall be required.
During an interagency site review on August 9, 2005, the site visit attendees
agreed that the site was successful and had met it goals with the exception of controlling
Phragmites. All of the agencies except for NCDCM also agreed that NCDOT could
close out the site. Since that meeting,NCDOT has proposed to NCDCM that the site be
closed out contingent upon the site being transferred to the U.S. Fish&Wildlife Service
(USFWS) and included in their land management program. The site will be integrated
into the overall refuge lands system as part of the Alligator River National Wildlife
Refuge. The site will also be subject to management actions that will provide the highest
quality natural wildlife habitat possible. Please see the attached USFWS letter dated
October 27, 2005 stating that the site will be incorporated into their land management
plan.
After reviewing the proposal from USFWS,NCDCM has provided a closeout
letter to NCDOT for the Mashoes Road mitigation site so long as the conditions stated in
the letter are met. Please see the attached NCDCM letter dated February 17, 2006 stating
that the site will be considered closed.

Dear Mr. Harris:
We have been advised of the current status of the Mashoes Road Mitigation Site adjacent to
Alligator River National Wildlife Refuge. It is our understanding that prior to a land transfer
action as part of the project mitigation plan, various agencies require a statement of
management intent from the refuge.
Land and waters of the Mashoes Road Mitigation Site, upon transfer to the U. S. Fish and
Wildlife Service, will be integrated into the overall refuge lands system as part of the Alligator
River National Wildlife Refuge. These lands will be subject to management actions that will
provide the highest quality natural wildlife habitat possible. Land based management actions
will be implemented so as to prevent degradation in quality of adjacent waters from these
actions. Examples of management actions include, but are not restricted to, use of prescribed
fire to mimic natural fire regimes and control of invasive and exotic species such as Phragmites.
All management actions will be contingent upon availability of funds and staffing.
From the National Wildlife Refuge System Act of 1997, "The mission of the National Wildlife
Refuge System is to administer a national network of lands and water for the conservation,
management, and where appropriate, restoration of the fish, wildlife, and plant resources and
their habitats within the United States for the benefit of present and future generations of
Americans." Alligator River National Wildlife Refuge was established for the purpose of
protecting natural resources, the conservation of threatened and endangered species, and
providing habitat for migratory birds and other wildlife. Lands of the Mashoes Road Mitigation
Site will be maintained and managed under the same mission and purpose statements.

Mr. Doug Huggett:
As you are aware,the Department has monitored the Mashoes Road Mitigation Site since its
construction in winte-of 1998. Located in Dare County, approximately I miles'north of Manns
Harbor on SR 1113 (Mashoes Road). This 399-acre site provides SVM restoration and
preservation, forest wetlands restoration and preservation, open water,and forested upland
hummocks. The Mashoes Road site provides compensatory mitigation for impacts associated
with R-2551 and K-4003. The west side of the site was planted with bottom land hardwood
species in Spring of 1999 and hydrologic monitoring gauges were installed throughout the entire
site in March of 19!. The east side of the site was constructed in 1999-nut was not planted at
that time in an attempt to control Phragmites. The east side of the site was planted with marsh
grass in the spring of 2001. NCDOT proposed to monitor the Mashoes Road mitigation site for
five years or until success criteria were met; with both hydrological and •egetation monitoring
_ conducted each year. After each growing season, annual monitoring reports were submitted to the
appropriate regulatory agencies.
Hydrologic success criteria stipulated that the forested wetland(west side) must be inundated or
saturated within 12-inches of the surface for a minimum of a consecutive 12.5% of the growing
season. Thus for the 258-day growing season in Dare County,the criteria is a consecutive 32
days. In the coastal marsh wetland (east side), success criteria include saturation or inundation
within 12-inches of the surface for 25% of the growing season or statistically the same as the
reference ecosystem. Table 1 provides a summary of the hydrologic data(the percentage of the
growing season that saturation was indicated) at each groundwater gauge location and surface
water gauge location for the past five years of monitoring.

criteria by yielding an average density of 482 trees per acre surviving. Individual yearly
monitoring data is provided within the annual monitoring reports submitted between 1999 and
2004.
During the annual monitoring report meeting on May 5, 2005,NCDOT and resource agencies
agreed that the Mashoes Road Mitigation Site could be closed and that monitoring could be
discontinued. NCDOT requests that the appropriate resource agencies provide documentation
stating that no further monitoring is required and that the site is closed. All remaining credits at
this site have been transferred to the Ecosystem Enhancement Program per the Memorandum of
Agreement dated July 22, 2003. If you have any questions about this project,please contact Mr.

FROM: Melissa Carle
DATE: December 16, 2005
SUBJECT: Mashoes Road Mitigation Site,Dare County
I agree that the Mashoes Road Mitigation Site can be closed out. While it is not DCM policy to
accept coastal marsh dominated by Phragmites australis as mitigation for CAMA wetland
impacts,I believe that this site can be considered a special exception. The United States Fish
and Wildlife Service have demonstrated their interest in acquiring the site and their dedication to
long-term management of the site, including control of Phragmites. This should ensure that the
site provides high quality coastal marsh habitat over the long run.

Dear Mr. Bell:
SUBJECT: Proposed Minor Modification to Department of the Army Permit
No. 199502334:Improvements to US 64-264, Including the construction of a new
Croatan Sound bridge, from west of Mains Harbor to NC 345, south of Manteo,
in Dare County; Federal Aid Project No. NIF-64 (6); State Project No.
8.T051401; TIP No. R-2551.
Please reference previous correspondence dated January 14, 1999 and a subsequent modification
to Department of the Army Permit No. 199502334 issued February 24, 1999. As noted in the
referenced permit modification. the planting of the Mashoes Road mitigation site was previously
scheduled to be complete by spring of 2000. However, the control of Phragmites australis has
not been successful. Since the removal of this species is a permit condition, the NCDOT feels
that additional time is necessary to control the Phragmites and to get the entire mitigation site
planted.
The NCDOT proposes to revise the planting schedule to reflect planting the site during the spring
of 2001. The presence of Phragmites within the site warrants herbicide treatment of this species.
The Phragmites was treated in June of 1999. However, the site remains contaminated with this
species. Since a non-selective herbicide treatment is not presently available for Phragmities, any
treatment after planting will damage the desired species. Therefore, the NCDOT requests that
the Department of the Army Permit be modified to allow continued treatment of the Phragmites
and to plant the site in the spring of 2001.

Additionally, the contractor has identified the need for 4 additional temporary 24.0" steel pipe
piles in Spencer Creek and 14 additional temporary 24.0" steel pipe piles adjacent to bridge span
22 in the Croatan Sound. The additional piles in Spencer Creek are similar to the previously
permitted safe harbor mooring piles in Spencer Creek. The extra piles are necessary to
accommodate additional equipment that has recently been employed in the construction of the
new bridge over the Croatan Sound. The location of these piles is depicted on sheet 2 of 2 in the
attached drawings. The piles will be used as a safe harbor mooring location in the event of
severe weather such as a hurricane or tropical storm. The 14 temporary 24.0" steel piles adjacent
to bridge span 22 will be used to assist in barge operations associated with the loading and
unloading of equipment and materials during bridge construction. The centerline of span 22 is
located at Station No. 46+36.06 and is approximately 2078.58 feet east (along the new bridge) of
the first bent on the western bridge terminus. All proposed piles are depicted in sheet 1 of 2 in
the attached drawings.
Thank you for your time and consideration. The Department respectfully requests that
processing of this modification request proceed as soon as possible. By copy of this letter, the
Department also requests that the Division of Water Quality and the Division of Coastal
Management also modify the 401 Water Quality Certification and the CAMA Major
Development Permit respectively. If you have any further questions or would like additional
information, please don't hesitate to call. Thank you for your time and consideration.

1999 Annual Report: Year 1 of Hydrologic Monitoring and West Side Vegetation
Monitoring
Site construction is not complete and monitoring will continue.
2000 Annual Report: Year 2 of Hydrologic Monitoring and West Side Vegetation
Monitoring
1. The 1998 plan for the Mashoes Road site has success criteria that differ from
those in the monitoring report. Is the May 1998 plan the approved plan and if so,
have any changes to that plan been approved other than the extension of the
planting deadline? Please clarify the approved hydrologic success criteria.
2. It is disappointing that the forested areas are not meeting vegetation success
criteria. What are some reasons NCDOT thinks this is happening? What species
will be re-planted?
3. Field staff from DCM's Elizabeth City office noted that significant patches of
Phragmites remain at the site and question whether planting done this spring will
succeed given it was postponed last year for Phragmites treatment.
4. The surface water gauges in the marsh restoration area seem to reflect the
reference data.
The groundwater gauges in the forested area fluctuate in depth quite a bit more than the
reference gauges for that area.
2001 Annual Report: Restart all monitoring. Year 1 of Hydrologic and Vegetation
Monitoring

Monitoring will continue. Phragmites is a problem at this site, but we recognize the
tremendous amount of this species in the immediate vicinity of the site and hope DOT
will continue to work to make sure it does not become a dominant part of the site over
time. We are interested in the potential Phragmites studies that may occur at this site and
on others.
2002 Annual Report: Restart all monitoring. Year 2 of Hydrologic and Vegetation
Monitoring
Monitoring will continue. Phragmites continues to pose a problem at this site. We
recognize the tremendous amount of this species in the immediate vicinity of the site;
however,note also that the vegetation plot comments in the report include Phragmites in
a majority of plots at the site. Compared to last year's report it appears the Phragmites
problem is getting worse. Frank Jennings noted that the site appears to be improving in
terms of the planted vegetation's survival,but suggests some transplanting of marsh
plants may be needed for areas that have not vegetated very well.
March 3, 2004
After consultation with USACE,DWQ and DCM,NCDOT agreed to allow USFWS to
do a prescribed burn on the Mashoes Road mitigation site. USFWS submitted guidelines
for the burn. No burning will be allowed in either the marsh restoration area or the
forested wetland, only in the preserved marsh area. This prescribed burn was deemed
necessary to mange fuel loading in the marsh and will be carried out as part of USFWS'
fuel control program for Alligator River National Wildlife Refuge.

(I tried to send this twice already, but kept getting an error on exceeding
maximum file size. I completely cut out the large photo showing all four
units in the compartment since that file was large. I am sending the .jpg
of the unit map in a separate email. )
Alligator River National Wildlife Refuge is seeking permission from the
North Carolina Department of Transportation to do a prescribed burn on a
portion of their property located on Mashoes Road just north of Manns
Harbor, NC. The refuge has been working with Byron Moore with NC DOT
([e-mail]) who has indicated that they would like the
concurrence of the Corps and CAMA before they grant Fish and Wildlife
Service permission to burn. The refuge would like to burn this area in
late January or in February 2004 .
The prescribed burn will be done in conjunction with burning refuge
property and is in a recognized burn unit identified in the refuge's Fire
Management Plan. Under the Fire Management Plan, each prescribed burn
requires the development of a Prescribed Fire Plan (PFP) . The PFP for this
unit has been written and is under review for final approval. This
particular PFP was written as one plan for the four units within the
Mashoes Fire Compartment. The e-mail attachments include a unit map, a
close up picture of the proposed fireline on DOT property, and selected
pages of text from the PFP.
(See attached file: Mashoes_obj .doc) (See attached file: unit picture.doc)
Please let me know if you would like any additional information. Thank you
for your help.

I. General Description of the Burn Unit
Physical Features and Vegetation Cover Types: East Lake,the Albemarle Sound, canals, and
Mashoes Road define the Mashoes Compartment boundaries. Unit 2 is the only unit not to
include private property as part of its burn acreage. Individual units are designated on the Units
Map as well as private property lines.
Juncus sp. and Spartina sp. are the dominant plants in the marshes, growing 3 to 5 feet tall and
thick with decadent vegetation. Marsh rings the water edges of each unit, but is a large portion
of Units 3 and 4. Pond pine pocosin has overstory pond pines 30 to 40 feet tall with gallberry,
wax myrtle, fetterbush, and red bay as the primary understory and mid-story species. Pond pine
pocosin composes most of Units 1 and 2, the western edge of Unit 3 along Mashoes Road, and
part of Unit 4. Loblolly pine hammocks scattered on slightly higher ground in Unit 4 have a
denser overstory and a more open understory than the pond pine pocosin. There is a transition
zone of vegetation from pond pine pocosin to marsh that has a large shrub component. The
shrubbier pocosin areas are found predominately in Unit 4 with some areas in each unit.
1

Primary Resource Objectives of Unit:
1. Manage the fuel loading in this compartment to reduce the risk of catastrophic wildfires
to the community of Mashoes.
2. Maintain and protect the wetland characteristics of this compartment by providing for the
protection of soils and hydrology in all management activities.
3. Manage the vegetation communities to maintain large-scale animal and plant diversity.
Objectives of Fire:
1. Burn out the available fine fuels so that a fire will not carry across this compartment for
one to two years.
2. Control shrub invasion into the marsh plant communities.
3. Reduce the accumulation of down woody fuels.
4. Top-kill the mid-story shrubs under the pond pine overstory with a low to medium
intensity burn.
Acceptable Range of Results:
1. Top-kill 40-60% of the shrubs in the pond pine pocosin and 90% of the shrubs in the
marsh.
2. Burn 50-70% of the available fine fuels within 4 feet of the ground.
3. Up to 10%pond pine or loblolly pine mortality is acceptable within the pocosin or
loblolly hammocks. Up to 100%mortality in pond pines growing in the transitional area
between marsh and pocosin or along the margins of the marsh is acceptable.

Habitat Conditions: Units 1, 2, and 3 have not been burned for over 20 years and have a large
build up of fuels. Unit 4 was burned in January of 2001. In all units, trees and shrubs are
expanding from the pond pine pocosin areas and encroaching into the marsh. Prescribed burns
should push the vegetation back towards marsh vegetation in these areas. Hurricane Isabel in
September 2003, increased fuel loads in all units when winds blew down trees and limbs as well
as large amounts of leaves and pine needles.
The wildland fuels are characterized in the NWCG publication NFES 2630 Stereo Series for
Quantifying Natural Fuels,Volume VI: Longleaf Pine, Pocosin, and Marshgrass Types in the
Southeast United States. Marsh vegetation is characterized by MG 08 Marshgrass with a fuel
loading of 8 tons/acre. Transitional shrub vegetation can be characterized as a mix of P-S 02
Shrub with a fuel loading of approximately 10 tons/acre and P-S 05 Shrub with a fuel loading of
approximately 7 tons/acre for an average of 9 tons/acre. Pond pine pocosin vegetation can be
characterized by P-W 02 Woodland with an approximate fuel loading of 4 tons/acre.
Type of Transect: N/A

III. Planning and Actions
Complexity Analysis Results: The overall complexity analysis for this compartment
determined prescribed burns in these units to be of moderate complexity. There was no
outstanding condition that warranted the units to be treated individually; therefore,the moderate
complexity determination is for all four units in the Mashoes Compartment. The use of aerial
ignition and burning on private property warrants the moderate determination. The complete
complexity analysis worksheet is attached at the end of the Prescribed Fire Plan.
Site Preparation: The power company will be contacted to clear around each power pole in
Units 3 and 4 prior to the burn. If the power company has not acted before the opportunity to
burn the units, the marshmaster will matt down the vegetation around each pole prior to burning.
Graduate Student Ben Poulter will be contacted the day before the burn to remove his data logger
from test wells in Unit 3. On either the day before or the morning of the burn, a fire tractor will
matt down a temporary line in Unit 4 leading from Mashoes Road to the pond behind the DOT
mitigation site. This will be used as the fire line to prevent fire from entering the mitigation site.
Weather Information Required: Alligator River Dispatch obtains current and predicted
weather information on a daily basis. Dispatch will obtain a general weather forecast and a
smoke management forecast from the North Carolina Forest Service (252-926-3041) or the
National Weather Service (Wilmington, 919-515-8200). Dispatch will also get a spot fire
weather forecast from the National Weather Service(http://spot.nws.noaa.gov/cgi-
bin/spot/spotmon?site=i1m) on the morning of the burn. Dispatch will report 1000 and 1400
weather data from the Alligator River RAWS station to the Burn Boss. A dedicated weather
observer(see Crew Assignments)will record hourly field weather observations and report this
weather to the Burn Boss.
3

Ignition Technique: The primary ignition method will be aerial ignition from plastic spheres.
The helicopter will use the primo machine to ignite the interior, dropping ignitions close enough
to create a low to medium intensity fire. Strip head fires will be the primary aerial ignition
method, but this can be modified at the discretion of the Burn Boss. Drip torches and the terra
torch will be used to secure blacklines on downwind firebreaks and around sensitive structures.
The helicopter will operate from the helispot at the Alligator River maintenance shop,but the
parking area for the NCWRC boat ramp can be used as an emergency helispot if necessary.
Refer to individual unit maps to reference named points in the following descriptions. If
possible, Unit 2 will be burned before Unit 1.
UNIT 1
The unit can be burned with a wind direction from 325 to 80 degrees. To totally avoid smoke on
the community of East Lake, winds between 10 to 65 degrees should be avoided. The critical
control points for this unit are the haulover point and cabin at and the entire eastern boundary
from 1 to 5 with adjacent private land and structures and Mashoes Road. If the unit is burned
with 135 degree wind(see sample burn sequence map), a ground ignition crew with the marsh
master would burn from point 8 to 7, securing the cabin and creek. Aerial ignitions would then
be used to secure this NW corner,referred to as Section B, igniting perpendicular to the wind
moving from NW to SE. As this section is secured, aerial ignition will work to burn out the
remainder of the unit. As the helicopter approaches the eastern side, a boat ignition crew will
burn from 1 to 2 securing the house and then move down the canal burning from 2 to 5. An
engine will be stationed on Ed Sawyer Road to watch for spots across this firebreak.
UNIT 2
This unit can be burned with a wind direction from 338-155 degrees and from 245 to 265
degrees. To totally avoid smoke on the community of East Lake, winds between 20 to 75
degrees should be avoided. If the unit is burned with a NE wind(see sample burn sequence
map), aerial ignition will ignite the peninsula area between points 5 and 4 and then from points 4
and 3 moving perpendicular to the wind from SW to NE. Ground crews will then
simultaneously pull a line from point 6 to 1 and from point 3 to 2, keeping up with the progress of
the aerial ignition. The final ignition will be a ground crew securing the canal along Mashoes
Road.
UNIT 3
This unit can be burned with a wind direction from 338 to135 degrees and from 245 to 270
degrees. The critical control points in this unit are the northern curve of Mashoes Road, the
eastern line between 1 and 2 and point 4 which are adjacent to private land, and the private
structure at 2. If the unit is burned with a NE wind(see sample burn sequence map), ground
ignition crews will burn from points 6 to 7 using the marshmaster and from points 6 to 5 using a
boat. After allowing time for the fire to back off Mashoes Road, aerial ignition will begin
moving perpendicular to the wind from SW to NE between points 6 and 7. Ground crews will
continue to pull the road from point 7 towards point 1 while the helicopter burns the interior.
The boat crew will move to point 2 to secure around the cabin, keeping an eye at point 4 to
ensure no spots onto the private island. The helicopter will finish igniting the unit.
9

UNIT 4
This unit can be burned with a wind direction from 350 to 140 degrees. To totally avoid smoke
on the community of East Lake, winds between 40 to 80 degrees should be avoided. The critical
control points for this unit are the cabin at point 4 and the DOT mitigation area by the south
boundary. If the unit is burned with a NE wind(see sample burn sequence map), the first
ignition would be along Mashoes Road from point 8 to point 1. Helicopter would then aerially
ignite perpendicular to the wind from 8 to 1 moving from SW to NE. Ignition crews would then
burn from point 1 to 2 and a second grew from 8 to 7 to 6. The helicopter would continue to
ignite the interior of the unit moving SW to NE. A boat crew would secure the cabin area
between points 4 and 5. There are several options for burning at point 4 with the exact location
for the blackline to be decided by the Burn Boss and Ignition Specialist on the day of the burn.
The Ignition Specialist must be sure that a low intensity fire enters the loblolly pine hammocks
in the unit.
Prescribed Fire Organization:
See Section VII, Crew and Equipment Assignments.
Other: At the discretion of the burn boss, the peninsula portion of Units 1 and 2 can be burned
differently than stated in the ignition sequences above. Unit 2 can be cut off with a line pushed
along the canal between points 6 and 4. The remaining narrow peninsular portion of Unit 2 can
then be aerially ignited when burning Unit 1.
Prescription Monitoring: A designated weather observer,using a belt weather kit or a Kestrel,
will monitor weather at the burn unit on an hourly basis. The weather observer will report
observations to the Burn Boss. More frequent observations will be made if any change in winds
or increases in fire behavior are noted. Dispatch will monitor weather radar and request periodic
spot weather forecasts to alert the Burn Boss to any changes in the weather. The Ignition
Specialist and the Burn Boss will monitor fire behavior on a continuous basis. Any changes in
fire behavior noted by firefighters should be reported immediately to the Burn Boss.
V. Smoke Management
Permits Required: The U.S. Fish and Wildlife Service has requested permission from the
North Carolina Forest Service to use VSmoke—GIS (version 1.0) in place of the current State of
North Carolina Smoke Management Guidelines. VSmoke is a computer modeling system that
models potential down-range impacts of smoke from prescribed burns. On the day of the burn,
Dispatch will give the District Forester the location of the burn, burn acreage, and estimated total
tons of fuel. If a unit is to be burned with separate ignitions, Dispatch will call in each ignition
division separately.
Fuel Available for Consumption in Tons/Acre: These units have a high fuel loading since
they have not been burned in 20 years, except for Unit 4 that was burned in 2001, and have
additional downed woody debris and leaf material courtesy of Hurricane Isabel. Only 2/3 of the
fuel is considered available for burning in the transitional shrub vegetation, so the tons of
available fuel were reduced from 9 tons/acre to 6 tons/acre.

SUMMARY
The following report summarizes the monitoring activities that have occurred in the past
year at the Mashoes Road Mitigation Site. Construction began on this site in 1998. The
west side of Mashoes Road was completed in early 1999 and was planted with trees;
this area was replanted in the Winter of 2000-01. The east side of Mashoes Road was
completed in the fall of 1999 but was not planted due to attempts to control Phragmites.
The east side of the site was planted with marsh grass in the spring of 2001. The site
must demonstrate hydrologic and vegetation success for a minimum of five years or
until the project is deemed successful.
The site contains nine groundwater-monitoring gauges on the west side, ten surface
gauges on the east side and one rain gauge. On the east side, there are a total of 167
random vegetation plots, and the west side has five permanent vegetation plots.
The daily rainfall data depicted on the monitoring gauge graphs is recorded from an on-
site rain gauge. Historical rainfall data used for the 30-70 percentile was recorded at
the Manteo Rain Gauge, maintained by the NC State Climate Office.
As requested by the resource agencies NCDOT used GPS to survey the slightly
elevated section in the center of the east side of the site on December 3, 2003. The
GPS survey resulted in an area of 0.19 acres. However, it is noted that some marsh
grasses are re-establishing in this area.
Hydrologic monitoring indicated that the site is continuing toward success. Under
average conditions for 2003, all nine of the groundwater gauges exceeded the
jurisdictional hydrologic success for at least 12.5% of the growing season. Nine of the
ten surface gauges showed steady tidal influence that maintained a water elevation
above zero under normal conditions for at least 25% of the growing season. Only one
gauge did not meet the criteria of 25% (22.3% for Gauge S2).
Vegetation monitoring, on the west side (tree area) of the restoration area, yielded 574
trees per acre; above the 320-tree requirement. A frequency of 77.0% for the targeted
vegetative species was identified on the east side of the site (marsh grasses area). A
vegetative scale value of 4.5 was recorded in this area.
Based on the monitoring results for this growing season, NCDOT proposes to continue
hydrologic and vegetation monitoring.

1.0 INTRODUCTION
1.1 Project Description
The Mashoes Road Wetland Mitigation Site is located north of Manns Harbor in Dare
County (Figure 1). It is bounded by US 64-264 to the south, the Alligator River National
Wildlife Refuge to the west, the Croatan Sound to the east, and is bisected into
east/west by SR 1113 (Mashoes Road).
A significant portion of the site (254 acres) was classified as a coastal marsh and fell
under the jurisdiction of the N.C. Division of Coastal Management. Another portion (107
acres) was classified as forested wetlands. The remainder of the site was comprised of
a 15-acre pond, borrow pits and cleared uplands from a sand mining operation, and
some forested uplands.
The site encompasses approximately 399 acres and is designed as a mitigation site
primarily for the new Croatan Sound Bridge between Manns Harbor and Manteo, TIP
Projects R-2551 and K-4003 (USACE Action ID No. 199502334).
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. These
guidelines stipulate criteria for both hydrologic conditions and vegetation survival. The
following report details the results of hydrologic and vegetative monitoring during 2003
at the Mashoes Road 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.

1.5 Permit Requirements
The Mashoes Road Mitigation Site was constructed primarily to compensate for impacts
to TIP Project R-2551 (USACE Action ID No. 199502334). Permit commitments stated
that Phragmites australis would be totally controlled in the marsh area.
The permit was modified in 2000, which allowed for marsh planting to be extended to
the spring of 2001. This gave NCDOT additional time to further treat for phragmites.
The site was treated for Phragmites in 2000, 2001, 2002, and 2003. The planting of
marsh grasses at the site was completed in Spring 2001.

2.0 HYDROLOGY
2.1 Success Criteria
In accordance with federal guidelines for wetland mitigation, the success criteria
for hydrology in the forested wetland (west side) states that the area must be
inundated or saturated (within 12 inches of the surface) by surface or ground
water for at least 12.5% of the growing season. Areas inundated less than 5% of
the growing season are always classified as non-wetlands. Areas inundated
between 5% - 12.5% of the growing season can be classified as wetlands
depending upon other factors, such as the presence of hydrophytic vegetation
and hydric soils.
In the coastal marsh wetland (east side), success criteria include saturation or
inundation within 12 inches of the surface for at least 25% of the growing season,
or statistically the same as the reference ecosystem.
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 growin• -ason is 258 days;
therefore the optimum duration for wetland hydrology i 32 day-. Also, local
climate must represent average conditions for the area.
2.2 Hydrologic Description
Historically, the wetlands on this tract were part of the coastal marsh of the
surrounding area. The primary sources of hydrology are tidal flushing of the
system and groundwater. After an extensive study of the site's hydrology, it was
concluded that filling of the ponds, and grading down of the upland areas would
elevate soils to a level that would saturate the soil stratum within the required
twelve inches or even flood the area during high tides. It was predicted that this
would be sufficient to restore wetland hydrology.
Six groundwater-monitoring gauges, eight surface gauges, and one rain gauge
were installed in 1999 (Figure 2). Three more groundwater-monitoring gauges
were installed during 2001 to evaluate potential drainage by the side canal. Also,
two additional surface gauges were added to the coastal marsh wetland area.
The rain gauge and monitoring gauges recorded daily readings of rainfall and
depth to groundwater, respectively. The surface gauges record tidal conditions
eight times daily; however, only one representative reading was used for
graphing and statistical purposes in this report.

2.3 Results of Hydrologic Monitoring
2.3.1 Site Data
For groundwater monitoring gauges on the west side of the mitigation site, the
maximum number of consecutive days that the groundwater was within twelve inches of
the surface was determined for each gauge. For surface gauges, the ground surface
was used (elevation zero) to give a better representation that the east side of Mashoes
Road was receiving daily tidal flooding. This number was converted into a percentage
of the 256-day growing season. Table 2 presents the 2003 results. In the table, "MR"
refers to Mashoes Road Mitigation Site, "S" refers to surface gauges, and "G" refers to
groundwater gauges. Reference gauges and new gauges are indicated.
In order to meet the success criteria for hydrology, the surface water gauges need to
maintain a water elevation above 0 for at least 25% of the growing season. Since the
criteria in the mitigation plan were unclear whether hydrology should be met in
maximum consecutive days or total days, the table (Table 2) shows both sets of data
(All ten gauges met the hydrology criteria using maximum consecutive and total days in
2003). tab,. IA, ,44.4
Appendix A contains a plot of the groundwater depth for each monitoring gauge. The
maximum number of consecutive days that the gauge met success above the 12-inch
depth is noted on each graph. Data determined to be erroneous was omitted; therefore,
some gaps appear in the plots. Precipitation events are included on each graph as
bars.

2.3.2 Climatic Data
Figure 4 represents an examination 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 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
rainfall year.
2.4 Conclusions
For the 2003 monitoring year, all nine groundwater gauges met the jurisdictional
hydrologic success of at least 12.5% of the growing season. Nine of the ten surface
gauges showed steady wind tidal influence that maintained a water elevation above
zero under normal conditions for at least 25% of the growing season. Only one of the
gauges did not meet the criteria of 25% (22.3% for Gauge S2).
The overall monitoring results show that the site performed successfully from a
hydrological standpoint in 2003.

3.0 VEGETATION: MASHOES ROAD MITIGATION SITE
(YEAR 3 MONITORING)
3.1 A Success Criteria (Trees)
NCDOT will monitor the site for five years or until the success criteria are met. A 320
stems per acre survival criterion for planted seedlings will be used to determine success
for the first three years. The required survival criterion will decrease by 10% per year
after the third year of vegetation monitoring (i.e., for an expected 290 stems per acre for
year 4, and 260 stems per acre for year 5). The number of plants of one species will
not exceed 20% of the total number of plants of all species planted.
3.1 B Success Criteria (Marsh Grasses)
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 count to 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%
vegetative 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.

3.4A Conclusions (Tree Area)
Of the 399 acres on this site, approximately 7 acres involved tree planting. This side
(Westside) of the site has become well vegetated with marsh grasses. There were 5
plots established throughout the planting areas, encompassing all plant communities.
The 2003 vegetation monitoring revealed an average density of 574 trees per acre,
which is well above the 320 trees per acre required by the success criteria.
3.4B Conclusions (Marsh Area)
• Percent Frequency of Target Species 77.0%
Frequency of 70% required.
• Vegetative Cover Scale Value 4.5
Scale Value of 5 required for year 5.
Of the 399 acres on this site, approximately 12.34 acres involved marsh grass planting.
There were 167 random plots established throughout the planting areas, encompassing
all plant communities. These plots were located with GPS. The northern side of the
site was treated for phragmites in April 2001 and in October 2003. The vegetative
coverage does not currently meet the success criteria. However, the vegetative
coverage and frequency do appear to be on track for year three.
Phragmites at the Mashoes Road Mitigation Site has been treated continuously
throughout the monitoring cycle. It appears that the herbicide treatments have been
somewhat successful in that the percent frequency of target species is above the 70%
required at the end of the 5-year monitoring cycle. Phragmites is and will continue to be
a nuisance at this site but the target vegetation is present. NCDOT will continue to treat
- and monitor the phragmites at the Mashoes Road Mitigation Site.
NCDOT will continue vegetation monitoring at the Mashoes Road Mitigation Site.

4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
The 2003-year represents the fifth full growing season (the third official season) that the
hydrologic data has been examined. All nine groundwater-monitoring gauges exceeded
the jurisdictional wetland hydrology for 12.5% of the growing season. When considering
maximum cumulative days, nine of the ten surface gauges met the 25% requirement of
daily flooding onsite during this same period. Only one of the gauges did not meet the
criteria of 25% (22.3% for Gauge S2). The overall monitoring results show that the site
performed successfully from a hydrology standpoint. ]1,)0 ErNily- s f-C (&Al auyt5.

SUMMARY
The following report summarizes the monitoring activities that have occurred in
the past year at the Mashoes Road Mitigation Site. Construction began on this
site in 1998. The west side of Mashoes Road was completed in early 1999 and
was planted with trees; this area was replanted in the Winter of 2000-01. The
east side of Mashoes Road was completed in the fall of 1999 but was not planted
due to attempts to control Phragmites. The east side of the site was planted with
marsh grass in the spring of 2001. The site must demonstrate hydrologic and
vegetation success for a minimum of five years or until the project is deemed
successful.
The site contains nine groundwater-monitoring gauges on the west side, ten
surface gauges on the east side and one rain gauge. On the east side, there are
a total of 167 random vegetation plots and the west side has five permanent
vegetation plots.
The daily rainfall data depicted on the monitoring gauge graphs is recorded from
an on-site rain gauge. Historical rainfall data used for the 30-70 percentile was
recorded at the Manteo Rain Gauge, maintained by the NC State Climate Office.
Hydrologic monitoring indicated that the site is continuing toward success. Under
average conditions for 2004, all nine of the groundwater gauges exceeded the
jurisdictional hydrologic success for at least 12.5% of the growing season. All ten
of the surface gauges showed steady tidal influence that maintained a water
elevation above zero under normal conditions for at least 25% of the growing
season.
Vegetation monitoring on the west side (tree area) of the restoration area yielded
482 trees per acre, which is above the 290-tree requirement. A frequency of
73.1% for the targeted vegetative species was found on the east side (marsh
grasses area) of the site. A vegetative scale value of 4.6 was recorded.
Per the letter from the Ecosystem Enhancement Program (EEP) to NCDOT
dated August 25, 2004, the EEP has accepted the transfer of all off-site
mitigation projects. The EEP will be responsible for fulfilling the remaining
monitoring requirements and future remediation for this project.

1.0 INTRODUCTION
1.1 Project Description
The Mashoes Road Wetland Mitigation Site is located north of Manns Harbor in
Dare County (Figure 1). It is bounded by US 64-264 to the south, the Alligator
River National Wildlife Refuge to the west, the Croatan Sound to the east, and is
bisected into east/west by SR 1113 (Mashoes Road).
A significant portion of the site (254 acres) was classified as a coastal marsh and
fell under the jurisdiction of the N.C. Division of Coastal Management. Another
portion (107 acres) was classified as forested wetlands. The remainder of the
site consisted of a 15-acre pond, borrow pits and cleared uplands from a sand
mining operation, as well as some forested uplands.
The site encompasses approximately 399 acres and is designed as a mitigation
site primarily for the new Croatan Sound Bridge between Manns Harbor and
Manteo; TIP Projects R-2551 and K-4003 (USACE Action ID No. 199502334).
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. 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 Mashoes Road 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
In accordance with federal guidelines for wetland mitigation, the success criteria
for hydrology in the forested wetland (west side) state that the area must be
inundated or saturated (within 12 inches of the surface) by surface or ground
water for at least 12.5% of the growing season. Areas inundated less than 5% of
the growing season are always classified as non-wetlands. Areas inundated
between 5% - 12.5% of the growing season can be classified as wetlands
depending upon other factors, such as the presence of hydrophytic vegetation
(\' and hydric soils.
In the coastal marsh wetland (east side), success criteria include saturation or
`� inundation within 12 inches of the surface for at least 25% of the growing season,
4 or statistically the same as the reference ecosystem.
The growing season in Dare County begins March 13 and ends November 25.
i i 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. Also, local
(\ `t' climate must represent average conditions for the area.
1 2.2 Hydrologic Description
L--,Historically, the wetlands on this tract were part of the coastal marsh of the
surrounding area. The primary sources of hydrology are tidal flushing of the
system and groundwater. After an extensive study of the site's hydrology, it was
concluded that filling of the ponds, and grading down of the upland areas would
4 . elevate soils to a level that would saturate the soil stratum within the required
twelve inches or even flood the area during high tides. It was predicted that this
would be sufficient to restore wetland hydrology.
Six groundwater-monitoring gauges, eight surface gauges, and one rain gauge
were installed in 1999 (Figure 2). Three more groundwater-monitoring gauges
were in ailed during 20-01 to evaluate poten ag tial draine by the side canal. Also,
two additional surface gauges were added to the coastal marsh wetland area.
(?).,
C The rain gauge and monitoring gauges recorded daily readings of rainfall and
i depth to groundwater, respectively. The surface gauges record tidal conditions
. I. eight times daily; however, only one representative reading was used for
�, ,l�l, graphing and statistical purposes in this report.

2.3 Results of Hydrologic Monitoring
2.3.1 Site Data
For groundwater monitoring gauges on the west side of the mitigation site, the
maximum number of consecutive days that the groundwater was within twelve inches of
the surface was determined for each gauge. For surface gauges, the ground surface
was used (elevation zero) to give a better representation that the east side of Mashoes
Road was receiving daily tidal flooding. This number was converted into a percentage
of the 256-day growing season. Table 1 presents the 2004 results. In the table, "MR"
refers to Mashoes Road Mitigation Site, "S" refers to surface gauges, and "G" refers to
groundwater gauges. Reference gauges and new gauges are indicated.
In order to meet the success criteria for hydrology, the surface water gauges need to
maintain a water elevation above 0 for at least 25% of the growing season. Since the
criteria in the mitigation plan were unclear whether hydrology should be met in
maximum consecutive days or total days, the table (Table 1) shows both sets of data
(All ten gauges met the hydrology criteria using maximum consecutive and total days in
2004).
Appendix A contains a plot of the groundwater depth for each monitoring gauge. The
maximum number of consecutive days that the gauge met success above the 12-inch
depth is noted on each graph. Data determined to be erroneous was omitted; therefore,
some gaps appear in the plots. Precipitation events are included on each graph as
bars.

2.3.2 Climatic Data
Figure 4 provides an examination of the local climate in comparison with historical data
in order to determine whether 2004 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 2003 and 2004. The historical data was
collected from the State Climate Office of North Carolina.
For the 2004-year, November (03'), January, March, and October experienced below
average rainfall. The months of February, April, May, July, and November all recorded
average rainfall for the site. December (03'), June, August, and September
experienced above average rainfall. The rainfall data from the onsite rain gauge was
used for the months of September-November. Overall, 2004 experienced an average
rainfall year.
2.4 Conclusions
For the 2004 monitoring year, all nine of the groundwater gauges exceeded the
jurisdictional hydrologic success for at least 12.5% of the growing season. All ten of the
surface gauges showed steady tidal influence that maintained a water elevation above
zero under normal conditions for at least 25% of the growing season.
The overall monitoring results show that the site performed successfully from a
hydrological standpoint in 2004.
EEP will begin monitoring the hydrology at the Mashoes Road Mitigation Site in 2005.

NCDOT will monitor the site for five years or until success criteria are met. A 320-stems
per acre survival criterion for planted seedlings will be used to determine success for
the first three years. The required survival criterion will decrease by 10% per year after
the third year of vegetation monitoring (i.e., for an expected 290 stems per acre for year
4, and 260 stems per acre for year 5). The number of plants of one species will not
exceed 20% of the total number of plants of all species planted.
3.1 B Success Criteria (Marsh Grasses)
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 count to 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%
vegetative 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.

3.4A Conclusions (Tree Area)
Of the 399 acres on this site, approximately 7 acres involved tree planting. The west
side of the site has become well vegetated with marsh grasses. There were five plots
established throughout the planting areas, encompassing all plant communities. The
2004 vegetation monitoring revealed an average density of 482 trees per acre, which is
well above the 290 trees per acre required by the success criteria.
3.4B Conclusions (Marsh Area)
• Percent Frequency of Target Species 73.1%
Frequency of 70% required.
• Vegetative Cover Scale Value 4.6
Scale Value of 5 required for year 5.
Of the 399 acres on this site, approximately 12.34 acres involved marsh grass planting.
There were 167 random plots established throughout the planting areas, encompassing
all plant communities. These plots were located with GPS. The vegetative coverage
and frequency appear to be on track for year four.
EEP will begin monitoring the vegetation at the Mashoes Mitigation Site in 2005.

4.0 OVERALL CONCLUSIONS/ RECOMMENDATIONS
The 2004-year represents the sixth full growing season (the fourth official season) that
the hydrologic data has been examined. All nine groundwater-monitoring gauges
exceeded the jurisdictional wetland hydrology for 12.5% of the growing season. When
considering maximum cumulative days, all ten surface gauges met the 25%
requirement of daily flooding onsite during this same period. The overall monitoring
results show that the site performed successfully from a hydrology standpoint.
Vegetation monitoring on the west side (tree area) of the restoration area yielded 482
trees per acre, which is well above the 290-tree requirement. A frequency of 73.1% for
the targeted vegetative species was found on the east side (marsh grasses area) of the
site. A frequency of 70% is required. A vegetative scale value of 4.6 was recorded
(scale value of 5 is required by year 5).
Per the letter from the Ecosystem Enhancement Program (EEP) to NCDOT dated
August 25, 2004, the EEP has accepted the transfer of all off-site mitigation projects.
The EEP will be responsible for fulfilling the remaining monitoring requirements and
future remediation for this project.

Primary Resource Objectives of Unit:
1. Manage the fuel loading in this compartment to reduce the risk of catastrophic wildfires
to the community of Mashoes.
2. Maintain and protect the wetland characteristics of this compartment by providing for the
protection of soils and hydrology in all management activities.
3. Manage the vegetation communities to maintain large-scale animal and plant diversity.
Objectives of Fire:
1. Burn out the available fine fuels so that a fire will not carry across this compartment for
one to two years.
2. Control shrub invasion into the marsh plant communities.
3. Reduce the accumulation of down woody fuels.
4. Top-kill the mid-story shrubs under the pond pine overstory with a low to medium
intensity burn.
Acceptable Range of Results:
1. Top-kill 40-60% of the shrubs in the pond pine pocosin and 9C% of the shrubs in the
marsh.
2. Burn 50-70% of the available fine fuels within 4 feet of the ground.
3. Up to 10% pond pine or loblolly pine mortality is acceptable within the pocosin or
loblolly hammocks. Up to 100% mortality in pond pines growing in the transitional area
between marsh and pocosin or along the margins of the marsh is acceptable.

Attention Michael F. Bell
Dear Colonel Youngbluth:
Please reference your February 4, 1999, request to modify Action ID No. 199502334 which
authorizes the widening of US 64-264 and the conipletion of a new bridge over Croatan sound near
Manteo, Dare County, North Carolina by the North Carolina Department of Transportation

the applicant and offer the following comments for your consideration.
If the Corps of Engineers determines that the problems encountered by the NCDOT at the Mashoes

preparation and transplanting.
We appreciate the opportunity to provide these comments.
