INTRODUCTION
Mitigation requirements for replacement of the Hobucken Bridge are described in the
Final Environmental Impact Statement Hobucken Bridge Replacement Atlantic
Intracoastal Waterway Bridge Pamlico County. North Carolina, dated June 1992 and
filed with the U.S. Environmental Protection Agency on June 26, 1992. Wetland types
to be impacted include palustrine forested, wetlands and estuarine scrub-shrub
wetlands.
Estuarine scrub-shrub (ESS) wetlands are expected to develop within the Roadway
Restoration Area, West (about .6 acres), and within the right-of-way beneath and
adjacent to the new bridge (about 3.1 acres) on the east side of the Atlantic
Intracoastal Waterway (AIWW) (Bridged Area, East), as shown on Figure 1. Unneeded
pavement and fill would be removed along the road restoration area and a 150-foot-
wide construction corridor would be cleared along the proposed bridge right-of-way.
These wetland areas would be planted for soil stabilization in a grass and legume seed
mixture. Shrub species such as myrtles, elders, and bay and hardwood tree species
would be expected to naturally revegetate this area after construction is complete.
However, these sites are within the proposed North Carolina Department of
Transportation (NCDOT) right-of-way and NCDOT would not allow trees to mature
there. Therefore, scrub-shrub vegetation would be maintained. Since these sites are
located adjacent to an estuarine creek (Roadway Restoration, West) or a canal and
the AIWW (Bridged Area, East), it is expected that the area of ESS habitat that would
develop in these areas would exceed 2 acres and fully offset the 1-acre loss of ESS
habitat resulting from project construction.
Restoration of 30 acres of degraded wetlands which are presently used for timber
production (pine plantation) is planned to offset the loss of 7 acres of wetlands and 15
acres of Goose Creek Game Management Lands as a result of the project. A detailed
plan for the site restoration is provided in the following pages.

MITIGATION GOALS AND OBJECTIVES
Objective. Our primary objective is to restore functional wetland values (primarily
wildlife habitat) in a presently degraded wetland and add to existing state-owned game
management lands to offset wetland and gameland losses as a result of the
construction of the Hobucken Bridge Replacement project. This would require land
acquisition, site preparation and planting, and the protection of the site from
encroachments.
Goals. Our goal is to convert 30 acres of palustrine pine plantation to 30 acres of
palustrine deciduous/mixed pine forest. This will be accomplished by selective
removal of pines and planting of broad- and needle-leaved deciduous species. Land
management would be permanently changed from pine production to the
establishment of old growth forest for the benefit of wildlife resources. Land ownership
will be transferred from private to state gamelands. Mitigation design considerations
including environmental and engineering concerns for the restoration of the mitigation
site were developed by the Wilmington District in coordination with state and federal
regulatory agencies as shown in Table 1.
SITE DEVELOPMENT
A site plan is included as Figure 1. In addition to the required 30-acre mitigation area,
a mitigation buffer is proposed to protect the site from encroachment or drainage by
adjacent landowners.
Land Acquisition. Hobucken mitigation lands, (Mitigation Area (North and South) and
the proposed Mitigation Buffer) will be acquired in fee as a part of project land
acquisition. After project completion, land ownership will be transferred to the State of
North Carolina for incorporation into the existing North Carolina Wildlife Resources
Commission (NCWRC) Goose Creek Gamelands. Long-term protection and
management of these mitigation areas will be the responsibility of the NCWRC.
Site Preparation. The primary area of focus is the 30-acre mitigation area. This site
is divided into two zones based on soil hydrology. The northern portion of the site
(Mitigation Area (North) is generally more mesic while the southern area (Mitigation
Area (South) is generally more hydric and contains scattered areas of shallow
emergent marsh. It is proposed that in the northern portion of the site the existing
pines would be thinned to 50-foot centers. Mature trees (.? 12 inches diameter at
breast height) and existing target deciduous species including red maple, wax myrtle,
hibiscus, and holly would not be cleared. With the exception of hand clearing for
planting access and maintenance of existing inspection transects, no significant
clearing is proposed in the southern portion of the mitigation site. It appears that
existing ditches in the mitigation area have not significantly altered the site's hydrology.
3
TABLE 1: MITIGATION DESIGN CONSIDERATIONS, HOBUCKEN BRIDGE REPLACEMENT.
1. General site management should result in the development of at least 30
acres of palustrine deciduous/mixed pine forest. Inclusions of palustrine or
estuarine scrub-shrub or emergent marsh are acceptable.
2. Soil disturbance should be kept to a minimum to avoid stimulating pine
regeneration.
3. Mechanical clearing should be avoided in the southern portions of the
mitigation site (mitigation area (South), Figure 1).
4. Mature trees > 12 inches diameter at breast height (DBH) and existing target
trees or shrubs should not be cleared.
5. Species to be planted should include a variety of broad- or needle-leaved
deciduous trees and shrub seedlings native to the area. The plant source should
not be located in excess of 200 miles north or south of Hobucken, North
Carolina. Mast (wildlife food) producers should be preferentially selected;
however, no more than 20 percent of the plantings should be of any 1 species.
6. Materials should be planted at a density expected to provide survival of 320
trees/acre 1 year after planting.
7. Monitoring should be conducted annually for a minimum of 3 years or until
the success criteria are met.
8. Long-term forestry practices by the North Carolina Wildlife Resources
Commission (NCWRC) on the Hobucken mitigation lands should be directed
toward the establishment of old growth forest for the benefit of wildlife resources.
4
Therefdre, hydrologic restoration is not proposed. The future removal of nontarget
species or modification of drainage ditches by the NCWRC for wildlife management
purposes may be required. No site preparation is proposed in the mitigation buffer.
Site Planting. Plant materials will be 18 to 24 inch bareroot seedlings from a source
within 200 miles north or south of Hobucken, North Carolina. Materials will be planted
at a density expected to result in the survival of 320 trees/acre, 1 year after planting.
Restoration areas already contain red maple, wax myrtle, hibiscus, and holly. These
species are considered target species and will not be cleared from the site, but will not
be planted. In the mitigation area (north), plant species will be equally distributed and
include laurel oak, cherrybark oak, swamp chestnut oak, flowering dogwood and
hickory. The mitigation area (south, with the exception of marsh areas) will be planted
in an equal distribution of water oak, willow oak, laurel oak, swamp dogwood, cypress,
and black gum.
Existing marsh areas will be unplanted; however, their margins will be planted in a 20-
foot-wide band of black gum, cypress and buttonbush. The mitigation buffer will not
be planted, with the exception of any marsh margins which will be planted as
described above.
Modifications in the planting plan may be made due to stock availability, or to improve
plant survival. Any modifications would be consistent with Table 1, item 5, and
approved by the Corps and the NCWRC.
MONITORING
Construction compliance will be determined by the Corps and the NCWRC. Mitigation
areas will be monitored by the Corps, the NCWRC, or a qualified contractor to assess
long-term site conditions and determine potential remedial actions.
Construction Compliance. Mitigation lands will be photo-documented (immediately
prior to site preparation, prior to planting, and upon completion) and an as-built
planting plan with documented quantities by species will be provided by the
contractor. Compliance with contract documents will be assessed by the Corps and
the NCWRC and a narrative report prepared. Seedling survival will be determined
based on the North Carolina Forest Service, Plantation Sampling Survival Procedure
(Forester's Field Handbook NCFS, 1982.)
Site Monitoring. A statistically valid sampling plan will be developed to determine
plant coverage by target versus nontarget species on mitigation lands. Plant coverage
will be assessed prior to site preparation, upon project completion, and at the end of
the first three growing seasons. An annual monitoring report will be prepared.
5
SUCCESS CRITERIA
The contractor will be required to assure a plant survival rate of > 320 trees/acre in
no less than 50 percent of the sample plots (NCFS 1982) over a 12-month assurance
period.
The site will be considered successful if at the end of 3 years it has achieved
development of at least 24 acres (80 percent of the original 30-acre goal) of palustrine
deciduous/mixed pine habitat, dominated (>50 percent) by target species, including
planted and naturally-occurring species. Inclusions of emergent marsh are acceptable
and will not be subtracted from the goal, with the exception of any portion that
occupies more than 50 percent of the total area.
Any remediation required during the monitoring period will be a Corps responsibility.
Management of the site during the monitoring period and long-term maintenance of
the site will be the responsibility of the NCWRC and will be directed toward the
establishment of old growth forest for the benefit of wildlife.

Dear Mr. Wilson:
Subject: Draft Mitigation Plan
Hobucken Bridge Replacement, AIWW
Pamlico County
The subject document has been reviewed and the following comments are offered as a
result of the review:
1. The document indicates that the ditches in the 30 acre mitigation site will not be
plugged because they have not significantly altered the site's hydrology. The
mitigation that is being proposed is enhancement. Therefore if an opportunity exists
to increase other functions besides wildlife habitat, it should be pursued. Unless these
ditches are performing some function not discussed in the document they should be
filled to increase the "wetness" of the area. Plugging the ditches should increase the
water quality functions by increasing the amount of time required for stormwater
runoff to enter the adjacent waters.
2. The plant species selected for the north mitigation area should be modified as follows:
delete flowering dogwood; hickory species should by Carya aquatica if available.
Other species that could be substituted for flowering dogwood include Fraxinus
caroliniana or. Fraxinus pennsvlvanica and Nyssa sylvatica var. biflora or N. a?,Luatica.
3. The success criteria should be, changed to read as follows:
"The contractor will be, required to assure a plant survival rate of 320 trees/acre in
100% of the sample plots for a period of 3 years."
"The site will be considered successful if at the end of 3 years it has achieved
development of at least 30 acres of palustrine de;1duous/rn1-.,ed pir. habitat."

INTRODUCTION
Mitigation requirements for replacement of the Hobucken Bridge are described in the
Final Environmental Impact Statement. Hobucken Bridge Replacement, Atlantic
Intracoastal Waterway Bridge. Pamlico County. North Carolina, dated June 1992 and
filed with the U.S. Environmental Protection Agency on June 26, 1992. Wetland types
to be impacted include palustrine forested, wetlands and estuarine scrub-shrub
wetlands.
Estuarine scrub-shrub (ESS) wetlands are expected to develop within the Roadway
Restoration Area, West (about .6 acres), and within the right-of-way beneath and
adjacent to the new bridge (about 3.1 acres) on the east side of the Atlantic
Intracoastal Waterway (AIWW) (Bridged Area, East), as shown on Figure 1. Unneeded
pavement and fill would be removed along the road restoration area and a 150-foot-
wide construction corridor would be cleared along the proposed bridge right-of-way.
These wetland areas would be planted for soil stabilization in a grass and legume seed
mixture. Shrub species such as myrtles, elders, and bay and hardwood tree species
would be expected to naturally revegetate this area after construction is complete.
However, these sites are within the proposed North Carolina Department of
Transportation (NCDOT) right-of-way and NCDOT would not allow trees to mature
there. Therefore, scrub-shrub vegetation would be maintained. Since these sites are
located adjacent to an estuarine creek (Roadway Restoration, West) or a canal and
the AIWW (Bridged Area, East), it is expected that the area of ESS habitat that would
develop in these areas would exceed 2 acres and fully offset the 1-acre loss of ESS
habitat resulting from project construction.
Restoration of 30 acres of degraded wetlands which are presently used for timber
production (pine plantation) is planned to offset the loss of 7 acres of wetlands and 15
acres of Goose Creek Game Management Lands as a result of the project. A detailed
plan for the site restoration is provided in the following pages.

MITIGATION GOALS AND OBJECTIVES
Objective. Our primary objective is to restore functional wetland values (primarily
wildlife habitat) in a presently degraded wetland and add to existing state-owned game
management lands to offset wetland and gameland losses as a result of the
construction of the Hobucken Bridge Replacement project. This would require land
acquisition, site preparation and planting, and the protection of the site from
encroachments.
Goals. Our goal is to convert 30 acres of palustrine pine plantation to 30 acres of
palustrine deciduous/mixed pine forest. This will be accomplished by selective
removal of pines and planting of broad- and needle-leaved deciduous species. Land
management would be permanently changed from pine production to the
establishment of old growth forest for the benefit of wildlife resources. Land ownership
will be transferred from private to state gamelands. Mitigation design considerations
including environmental and engineering concerns for the restoration of the mitigation
site were developed by the Wilmington District in coordination with state and federal
regulatory agencies as shown in Table 1.
SITE DEVELOPMENT
A site plan is included as Figure 1. In addition to the required 30-acre mitigation area,
a mitigation buffer is proposed to protect the site from encroachment or drainage by
adjacent landowners.
Land Acquisition. Hobucken mitigation lands, (Mitigation Area (North and South) and
the proposed Mitigation Buffer) will be acquired in fee as a part of project land
acquisition. After project completion, land ownership will be transferred to the State of
North Carolina for incorporation into the existing North Carolina Wildlife Resources
Commission (NCWRC) Goose Creek Gamelands. Long-term protection and
management of these mitigation areas will be the responsibility of the NCWRC.
Site Preparation. The primary area of focus is the 30-acre mitigation area. This site
is divided into two zones based on soil hydrology. The northern portion of the site
(Mitigation Area (North) is generally more mesic while the southern area (Mitigation
Area (South) is generally more hydric and contains scattered areas of shallow
emergent marsh. It is proposed that in the northern portion of the site the existing
pines would be thinned to 50-foot centers. Mature trees (> 12 inches diameter at
breast height) and existing target deciduous species including red maple, wax myrtle,
hibiscus, and holly would not be cleared. With the exception of hand clearing for
planting access and maintenance of existing inspection transects, no significant
clearing is proposed in the southern portion of the mitigation site. It appears that
existing ditches in the mitigation area have not significantly altered the site's hydrology.

TABLE 1: MITIGATION DESIGN CONSIDERATIONS, HOBUCKEN BRIDGE REPLACEMENT.
1. General site management should result in the development of at least 30
acres of palustrine deciduous/mixed pine forest. Inclusions of palustrine or
estuarine scrub-shrub or emergent marsh are acceptable.
2. Soil disturbance should be kept to a minimum to avoid stimulating pine
regeneration.
3. Mechanical clearing should be avoided in the southern portions of the
mitigation site (mitigation, area (South), Figure 1).
4. Mature trees > 12 inches diameter at breast height (DBH) and existing target
trees or shrubs should not be cleared.
5. Species to be planted should include a variety of broad- or needle-leaved
deciduous trees and shrub seedlings native to the area. The plant source should
not be located in excess of 200 miles north or south of Hobucken, North
Carolina. Mast (wildlife food) producers should be preferentially selected;
however, no more than 20 percent of the plantings should be of any 1 species.
6. Materiais should be planted at a density expected to provide survival of 320
trees/acre 1 year after planting.
7. Monitoring should be conducted annually for a minimum of 3 years or until
the success criteria are met.
8. Long-term forestry practices by the North Carolina Wildlife Resources
Commission (NCWRC) on the Hobucken mitigation lands should be directed
toward the establishment of old growth forest for the benefit of wildlife resources.
4
N+
Therefore, hydrologic restoration is not proposed. The future removal of nontarget
species or modification of drainage ditches by the NCWRC for wildlife management
purposes may be required. No site preparation is proposed in the mitigation buffer.
Site Planting. Plant materials will be 18 to 24 inch bareroot seedlings from a source
within 200 miles north or south of Hobucken, North Carolina. Materials will be planted
at a density expected to result in the survival of 320 trees/acre, 1 year after planting.
Restoration areas already contain red maple, wax myrtle, hibiscus, and holly. These
species are considered target species and will not be cleared from the site, but will not
be planted. In the mitigation area (north), plant species will beregqually distributed and
include lam oak, cherry a& oak, sw&Np"'chestnut oak, flowenng?ogwood and
icko The mitigation area (south, with the exception of marsh areas) will be planted
bat ual distribution of water oak, willow oak, laurel oak, swamp dogwood, cypress,
- i n eq
C; ?W.,f? and black gum. rj:?,`? Fes",
Existing marsh areas will be unplanted; however, their margins will be planted in a 20-
foot-wide band of black gum, cypress and buttonbush. The mitigation buffer will not
be planted, with the exception of any marsh margins which will be planted as
described above.
Modifications in the planting plan may be made due to stock availability, or to improve
plant survival. Any modifications would be consistent with Table 1, item 5, and
approved by the Corps and the NCWRC.
MONITORING DW,
Construction compliance will be determined by the Corps and the NCWRC. Mitigation
areas will be monitored by the Corps, the NCWRC, or a qualified contractor to assess
long-term site conditions and determine potential remedial actions.
Construction Compliance. Mitigation lands will be photo-documented (immediately
prior to site preparation, prior to planting, and upon completion) and an as-built
planting plan with documented quantities by species will be provided by the
contractor. Compliance with contract documents will be assessed by the Corps and
the NCW and a narrative report prepared. Seedling survival will be determined
based on the North Carolina Forest Service, Plantation Sampling Survival Procedure
(Forester's Field Handbook NCFS, 1982.)
Site Monitoring. A statistically valid sampling plan will be developed to determine
plant coverage by target versus nontarget species on mitigation lands. Plant coverage
will be assessed prior to site preparation, upon project completion, and at the end of
the first three growing seasons. An annual monitoring report will be prepared.

SUCCESS CRITERIA
/acre in
The contrac will be required to assure a plant survival rate of > 320 trees
no less tl 0 rcent of the sample plots (NCFS 1982) over a 12-month assurance
period.
The site will be considere cessful if at the end of 3 years it has achieved
development of at least a es (80 percent of the original 30-acre goal) of palustrine
deciduous/mixed pine itat, dominated (>50 percent) by target species, including
planted and naturally ccurring species. Inclusions of emergent marsh are acceptable
and will not be sub acted from the goal, with the exception of any portion that
occupies more th n 50 percent of the total area.
Any remediati?_n required during the monitoring period will be a Corps responsibility.
Management/of the site during the monitoring period and long-term maintenance of
the site will be the responsibility of the NCWRC and will be directed toward the
establishment of old growth forest for the benefit of wildlife.

MEMORANDUM
TO: Lorraine Shinn
t? (Gi??_
THROUGH: Roger K. Thorpe
FROM: Deborah Sawyer
SUBJECT: A-95 Review
Final EIS
Hobucken Bridge Replacement - AIWW
Pamlico County
The above subject document has been reviewed by this office.
Upon receipt and review of the Public Notice for this project, this
office will make regional rcommendations as to issuance of the
Section 401 Water Quality Certification to the Division's Central
Office in Raleigh. This review will include a determination and
recommendation as to no practical alternative and whether impacts
to surface waters (including wetlands) have been minimized.
Furthermore, a review of mitigation proposals will be performed and
recommendations made.
This office wishes to restate its concern of the wetland
delineations being performed by the branch of the U.S. Army Corps
of Engineers which performs civil works projects. The Corps has a
Regulatory Branch which has the authority to issue permits as well
as determine compliance with said permits. It is this office's
understanding that other Corps Districts' Civil Works sections do
not perform wetland delineations and approve of said delineations
in compliance of Section 404 of the Clean Water Act. They have
compliance responsibility but not regulatory responsibility. The
Regulatory Branch normally has that responsibility.
If you have any questions or comments, please call this office
at 946-6481. Thank you.

Dear Col. Tulloch:
RE: Hobucken Bridge Replacement, Pamlico County
DEM Project # 92106
On March 9, 1992, I received an application from you for a
401 Water Quality Certification for your project entitled
Hobucken Bridge Replacement in Pamlico County. Our existing
regulations (15A NCAC 2H .0501 (a)) require that all applicants
for 401 Certifications submit seven complete copies of 401
Applications. These copies must be supplied by the Division of
Environmental Management to various state and Federal agencies as
specified in the same regulations. Having copies available for
simultaneous review by other agencies will reduce the overall
processing time for your permit application. In the past, we
have not enforced this requirement and have seen processing time
slowed significantly.
Therefore, please send four additional copies of your 401
Certification application so we can initiate the comprehensive
review required by our rules. I am unable to do this copying
since there are numerous applications with this problem and our
regulations state that the applicant must supply these copies.
If you have any questions, please call me at 919/733-1786.

906(b) of the Water Resources Development Act of 1986 (PL 99-662) gives the
authority to the Corps of Engineers to approve post-authorization mitigation
(including land acquisition). The Act under Section 906(d), requires that
impacts to bottomland hardwoods be mitigated in-kind, to the extent possible.
The loss of 6.0 acres of palustrine forested wetlands and 1.0 acres of
estuarine scrub-shrub wetlands associated with the road fill is significant
and requires the development of a mitigation plan. The objective is to
replace, as completely as possible, the wetland values lost, with in-kind
replacement being the preferred alternative. The following paragraphs present
a description of the alternatives, alternative evaluation, and the recommended
plan.
Mitigation Alternatives.
In developing a mitigation objective and mitigation alternatives for the loss
of wetlands, the relative habitat values, developed as part of the wildlife
habitat evaluation for the study area (Appendix C), were used as an indicator
of the value of affected wetlands. Values range from low (1) to high (5) for
wetland and upland communities. The 6.0 acres of palustrine forested wetlands
have a relative habitat value of high-moderate (4) for the pine dominated
wetlands (4.5 acres) and a relative habitat value of high (5) for the
deciduous wetlands (1.5 acres), and the 1 acre of palustrine scrub-shrub
wetlands has a high relative habitat value (5). This results in a total loss
of 30.5 relative habitat units (acres x relative habitat value). The
functional value of these wetlands, in terms of characteristics such as
groundwater recharge, floodflow alteration, and-sediment and nutrient control
was determined to be good.
In developing and evaluating alternatives, careful attention was given to the
location of lands relative to the proposed alignment and adjacent properties.
Mitigation lands located adjacent to or in proximity to the new alignment
allows the area to be used during construction for staging and access.
Location of mitigation lands adjacent to other parcels of wetlands or forested
habitat increases its value as a contiguous wetland complex and avoids
isolated wetland parcels.
Alternative 1. Manage lands within the acquired right-of-way.
Because of the road fill required for the approaches 'to the bridge, there
is little land available for management. The land under the bridge is
needed for access. As a result, this alternative was not considered to be
feasible.
Alternative 2. Recreate wetlands.
Some of the land within the study area has been ditched and drained to
allow for timber management and agriculture. It would be feasible on some
of these parcels to -fill the interior ditches and plug the drainage
outlets in order to allow saturated soil conditions to return. The areas
could then be planted with wetland species. This would raise the existing
31

A%%
habitat value of 'the drained areas, which are predominantly low (2) to
high-moderate (4) in value, to a high-moderate (4) to high value (5) ove
a period of time and return some of the sites wetland functions.
Alternative 3• Restore the value of existing wetlands.
Some parcels of forested.wetlands within the study area have been-cleare
and partially drained and are being used.for timber and for agricultural
production without the use of extensive Jnterior ditches. This has
resulted in a loss of wetland values associated with the loss of
vegetation and changes in hydrology but the interior of the sites retain
saturated soil conditions. Acquisition of these lands, which have an
existing value of low-moderate (2) to high-moderate (4), minor grading,
and planting would protect them from future ditching and clearing,
reestablish.wetland vegetation, and improve their wetland value and
function.
Alternative 4. Convert uplands to wetlands.
Upland areas within the study area could be purchased and converted to
forested wetlands through site modification. This would require
excavation, grading and replanting. The habitat value of the uplands,
which can range from low .(1) to high (5) depending on the vegetation anc..
adjacent land cover, would be replaced by the :habitat and functional va7
of the wetlands.
Alternative Evaluation.
The mitigation alternatives were evaluated to determine the most cost
effective approach for satisfying the mitigation objective. As part of the-
evaluation, each alternative was applied to each of the existing relative
habitat values to determine the acreage and cost requirements for each type
land considered., Table 3 presents-the evaluation of mitigation alternatives
and Figure 7 presents a cost comparison of the mitigation measures.
Obviously, lands with low relative habitat and wetland functional values,
offer the greatest potential for output in terms of increased values.
Alternative 3 proved to be 'Ine most economical approach to mitigation and w
further explored for parcel& that could be purchased. No sites with an
existing relative habitat value of low (1) were found adjacent to Goose Cre
Game Management Lands, so lands of low-moderate (2) were sought. A site
located north of the proposed alignment and adjacent to Goose Creek Game
Management Lands was identified. The site has been severely disturbed from
past timbering activities and drainage and now consists of a dense stand of
loblolly pine and a clear cut area with loblolly pine, red maple, and sweet
gum saplings. Purchase of the site, site preparation (grading and drainage'
fills),-and,replanting would protect it from further land disturbing
activities, allow the vegetation to mature into a palustrine mixed
pine/deciduous'forest;- restore the wetland functional values of the site,
add-to--the existing.State owned game management lands. The relative habit,,
value of the site can be raised from its existing value of low-moderate (2)
32

un
to=high (5). -This would result in=an output of 3 relative habitat units per
acre.and would.require::mitigation actions on approximately 10 acres to
compensate for the` 30.5, relative habitat units lost (30.5 relative habitat units
divided by 3 relative habitat units/acre) assuming that the full value would be
realized immediately. In order to account for the time to achieve the full
value,of the mitigation lands, it Js assumed that only two habitat units can be
gained per acre and that 15 acres will be required to compensate for the 30.5
relative habitat, units lost (a 2 to 1 ratio was recommended by the U.S. Fish and
Wildlife Service which would.require a total of 14 acres).
LOSS OF GOOSE CREEK: MANAGEMENT LAND
Approximately 15 acres of Goose Creek Game Management Lands would be included in
the right of way for the proposed project. The total habitat value for the
displaced management lands is 63.0 relative habitat units (12.0 acres X RHV(4)
plus 3.0 acres X RHV (5)). These losses include four acres of the filled
wetlands and their associated habitat value described previously (the remaining
3 acres of filled wetlands are on private property). Total relative habitat
units for the filled wetlands on Goose Creek Game Management Lands is 17 RHUs (3
acres X RHV (4) plus 1 acre X RHV (5)). Mitigation for the loss of State owned
lands would require replacement with lands of equal habitat value. The total
value to be replaced would be 46.0 RHUs (63.0 RHUs minus 17 RHUs). This can be
combined with the plan for the replacement of wetland losses. Given that the
land in the vicinity of the mitigation area for wetland losses has a habitat
.value of 2 relative habitat units (RHU), an additional 15 acres of land would
have.to be purchased and managed to account for the 46 relative habitat units
lost (15 acres X 3 RHU = 45 RHU's).
Figure 8 shows the location of the proposed mitigation site for wetland and
habitat losses.
LOSS OF EXISTING BRIDGE
In anticipation of a determination that the existing bridge is eligible for the
National Register zof Historic Places and that the proposed action will have an
adverse effect, three alternative treatments of the property have been analyzed.
These alternatives include preservation in place, moving the property to another
location, and Historic American Engineering Record photodocumentation of the
property followed.by razing the structure.
In-place preservation of the Hobucken Bridge is not a feasible or prudent
alternative. Leaving the existing bridge in place after construction of the new
bridge would present a hazard to navigation and would not allow for the
efficient use of the waterway. If the bridge is left in place, it would have to
be left in the open position which would present a hazard to navigation and
would preclude its use for any adaptive purpose. The removal of the existing
bridge and replacement' with a high-rise structure was authorized by Congress to
eliminate continued Federal involvement in maintenance and operation of AIWW
bridges. In order to leave..the existing bridge in place, a congressional

ENVIRONMENTAL COMMITMENTS
The following list is a summary of environmental commitments related to the
replacement of the existing Hobucken Bridge. These commitments address
aggreements made with state agencies,,mitigation measures, and construction
practices.
1. The existing bridge will be made available to the state of North
Carolina (if desired by the State) for use in the Artificial Reef
Program.
2. Thirty acres of land as identified on Figure 8 of the FEIS will be
purchased for mitigation. These lands will be become part of the Go,
Creek Game Management Lands and will be managed by the State. Finale
details of the mitigation plan will be developed during preparation:'
project.plans and specifications.
3. Upland areas within the proposed. right-of-way will be used as a stag
area for construction material.and equipment. No wetland areas will
used: Staging areas will be cleaned up, graded, and planted after
construction
4. Any asbestos containing material found in the-structures to be remov
will be disposed of in an Environmental Protection Agency approved
disposal site.
5. Appropriate erosion and sedimentation control measures will be appli
during construction.
6. Drainage plans will be developed to avoid increase in mosquito
sites.
