WAYNE MCDEVITT
SECRETARY Dear Dr. Bruton:
This letter is in response to your correspondence dated June 17, 1999 to the Division of Coastal
Management and recent phone conversations with Shannon Simpson of your staff regarding the
DONNA D. MoFFiTr
DIRECTOR regulatory release of the New Hanover County Mitigation Sites located near Bridge No. 1 over
Spring Branch and Bridge No. 2 over Smith Creek on SR 1175 (North Kerr Avenue).
It appears, according to the description in your letter, that most of the success criteria for these
mitigation sites have been met. DCM concurs with your recommendation to discontinue
monitoring of the B-20598-2156 mitigation site since the goals of the mitigation project have
been met to the extent that a swamp forest representative of a natural swamp forest community
has been restored.
Please note, the success criteria for this site as outlined in the document titled "Restoration
Guidelines," an attachment to your 1992 CAMA permit application, includes proper species
composition as follows: bald cypress, Taxodium distichum, (35%); black gum, Nyssa sylvatica,
(35%); and water oak, Quercus nigra, (30%). Your letter dated June 17, 1999 does not mention
water oak as a component of this site in its present condition, therefore it appears that the oak
component of this swamp forest has not survived. This is disappointing. However, Kelly
Williams, DCM Wetland Restoration Specialist, has visited these sites and agrees that swamp
forest has been satisfactorily restored at both locations.
If you have any questions, please call me or Kelly Williams at [phone]. Thank you.

The North Carolina Department of Transportation(NCDOT) has monitoredt_thE
referenced mitigation sites since 1995. No hydrologic monitoring was required on:this
site. Vegetation monitoring has been conducted for three growing seasons.
The sites are located near Bridge No. 1 over Spring Branch and Bridge No. 2
over Smith Creek on SR 1175 (North Kerr Avenue) in New Hanover County. These
sites consist of restoration of the following swamp forest species:
Bald Cypress - Taxodium distichum
Black Gum - Nyssa sylvatica
Water Oak - Quercus nigra
The sites were planted in December of 1994. Areas at both sites under the old
bridge approaches were graded to natural ground level and planted with appropriate
species. No monitoring plots were established. NCDOT began monitoring the site in
1995. The success criteria established requires a survival rate of 32 stems per 0.1
acres (320 per acre).
At the time the 1996 Annual Report was prepared, the sites were thriving well as
brackish (tidal) marshes with a dense stand of Juncus and Spartina sp. Colonization of
these marsh species was beginning throughout the sites due to adjacent marsh habitat.
However, it had been determined by visual observation that none of the trees planted
had survived. Supplemental planting was done at both sites in January 1997.
As of the 1997 Annual Report, a site inspection revealed that the replanted trees
were doing well throughout both areas. From visual observation it was concluded that
there were greater than 32 stems per 0.1 acre on both sites. The sites continued to
function as brackish (tidal) marshes. Site 1 (east side of bridge) was growing well with a
mixture of black willow, bald cypress, tulip poplar, black gum, Juncus, giant cordgrass,
and cattails. Site 2 (west side of bridge) also was successfully growing with a
predominant mixture of bald cypress and black gum, along with some wax myrtle, alder
and pine on the higher elevations at the bottom of the fill slope.
By visual observation during the third year of vegetation monitoring in 1998, the
average tree density remained greater than 320 stems per acre on both of the planted
sites. The 1998 Annual Monitoring Report concluded that the site has met the
vegetation success criteria.
At this time, NCDOT would recommend discontinuing monitoring of the 6-
2059113-2156 mitigation site. If you have any questions, please call Shannon Simpson,
Natural Systems Specialist, at 733-7844 ext. 330. Thank you for your continued

1.0 INTRODUCTION
1.1 Project Description
Designed as wetland restoration, the two sites are located in New Hanover
County. This project consists of two sites located near bridge 1 over Spring
Branch and bridge 2 over Smith Creek on SR 1175, North Kerr Avenue (Figure
1).
1.2 Purpose
The purpose of this report is to detail the vegetation monitoring for 1998 at the B-
2059 and B-2156 Mitigation Site. No hydrologic monitoring was required on this
site.

2.0 VEGETATION
2.1 Success Criteria
Success Criteria states that there must be a survival rate of 32 stems per 0.1
acre (320 per acre).
2.2 Description of Species
The following tree species were planted in the Wetland Restoration Area:
Taxodium distichum, Bald Cypress
Nyssa sylvatica, Black Gum
Quercus nigra, Water Oak
2.3 Results of Vegetation Monitoring (3 year)
No monitoring plots were established; however, site inspection revealed that the
' replanted trees were doing well throughout both planted areas. The site is
thriving well as a brackish (tidal) marsh with a dense stand of Juncus and
Spartina. Site #1 (east side of bridge) continues to grow well at this time with a
mixture of Bald Cypress, Tupelo Gum, Juncus, and cattails. Site #2 (west side of
bridge) also continues to grow well with a predominant mixture of Bald Cypress
and Black Gum; however, some Wax Myrtle, Alder, and Pine were identified
along the bottom of the fill slope. By visual observation, it is clearly evident that
the average tree density is well above 320 stems/acre. There is also some
volunteer juncus, cattail, and water lily.

2.4 Conclusions
Areas under both old bridge approaches were graded to natural grade and
planted with the appropriate hardwood species. There were no plots established;
however, by visual observation during the third year vegetation monitoring, it is
t obvious that the average tree density is greater than 320 stems per acre on both
of the planted sites. The naturalization of marsh species is also continuing
throughout the site.

Dear Wayne:
E. NORRIS TOLSON
SECRETARY
Re: NCDOT/Resource Agency Partnering Meeting - Monitoring Guideline
A meeting was held on Jul), 22. 1998 in the NCDOT Photogrammetry Conference
Room in Raleigh to discuss monitoring guidelines for the 1998 Annual Monitoring
Reports. Please find attached a list of those in attendance and the meeting agenda.
Following introductions, Charles Bruton described the purpose of the meeting and
opened the floor to David Franklin for any opening comments. David said he looked
forward to resolving any previous discrepancies in the 1997 Annual Monitoring Reports
and discussing ways to better present monitoring results in this year's monitoring reports.
Phil Harris moderated the meeting.
HYDROLOGIC MONITORING
NCDOT and the Corps agreed wetland mitigation sites must meet the guideline
for hydrology (1987 Manual) using consecutive days and not cumulative days of the
locally designated growing season. Wetland hydrology criteria in the 1987 Manual notes
that a site must be seasonally inundated or saturated (within 12 inches of the surface)
greater than 12.5 percent of the local growing season. NCDOT will re-evaluate the 1997
monitoring data to reflect consecutive days rather than cumulative days of the growing
season.
Regarding monitoring well data, David wants to see compliance is met and that
the sites are working. Phil noted that NCDOT is taking a close look at recurring
problems associated with monitoring well installation and maintenance. In cases where
hydrology was failing for a particular site, NCDOT would be unable to remediate the site
until the following year due to seasonal constraints and the necessity to collect specific
hydrographic information. In discussing what was considered to be hydrologic success,

David Franklin said the 1987 Manual was the official guideline. However, he went on to
suggest that the Corps would be interested to see a more detailed breakdown of the well
data and would not be opposed to hydrologic success based on a longer monitoring
period with less than a 12.5 % success criteria. He also mentioned well data that falls
' below the 12 inch threshold may also be examined as a special case. Mike Bell suggested
site remediation should occur now rather than waiting until December. NCDOT, in
coordination with the Corps, will identify unsuccessful sites and work together to
determine how the site is failing and the best remediation techniques to implement.
VEGETATION MONITORING ISSUES
Due to NCDOT's demand for hardwood seedlings there is a shortage of seedlings
' this year and there was none available for remediation efforts. There is a minimum one
year lead time for ordering seedlings. In a situation on a site where the well data is good
but the vegetation is not successful the Corps stated they would review it on a site by site
' basis. In cases of remediation, Charles said it was almost impossible to grade and plant a
site before the winter deadline.
' Randy Wise requested an extension of the August/ September time period t:,
obtain the vegetation monitoring data for the sites. After discussing this issue, it was
agreed that the marsh sites would be evaluated in August and the hardwood sites could be
evaluated as late as October and November before leaf drop. The NCDOT will send a
"blanket" letter to the Corps to modify all permits to reflect the revised vegetation
monitoring period. Phil mentioned that although there would be an extension of the
' monitoring period for vegetation, monitoring reports would continue to be completed and
distributed by the end of December. Randy said they often perform random site visits
throughout the year to see how vegetation is performing and would perform supplemental
planting if noted early enough in the growing season.
' Ken Jolly asked who was responsible for downloading wells and did they look at
vegetation. Beth Smyre said the Geotechnical Unit downloaded well data and notified
her of any vegetation issues. The Corps requested that proposed remediation for
' hydrology and vegetation be included in monitoring reports. NCDOT and the Corps will
coordinate any remediation measures. Randy expressed their commitment to remediate
vegetation as soon as possible.

The discussion turned toward planted versus volunteer species. The Corps does
not want to see volunteer species included in survival rate calculations for planted
species. Randy noted the survival rate is set at 50% or higher. David wanted to make
sure that the sites meet the target species requirement in stems per acre, not a percentage
(except for older sites set up for percentage). David also wanted to see the distribution of
species planted and volunteer. Randy said it is often difficult to identify certain species
during the first two years (several oak species often look alike as saplings). Generally it
is easier to differentiate the species by the third year. The Corps wanted to know if there
was a way to identify the planted species at planting. However, the planting procedure is

---i
Ll

f'

so labor intensive now it would make it impossible to do so. The 50 foot by 50 foot
monitoring plots are chosen and staked in the field after planting has occurred. The
Corps wants NCDOT to note the unwanted volunteer species and to identify possible
remediation to make sure these species do not dominate the site. The NCDOT and the
Corps agreed that the distribution of species is such that no species dominates more than
20 % of the distribution. Red maple and sweet gum are generally not to be planted to
insure good numbers of target species.
HYDROLOGIC SUCCESS CRITERIA
The incorporation of reference systems in determining success was discussed.
David concluded that if a particular site failed under the 1987 Manual guidelines, then
NCDOT had the option of comparing site parameters to reference site parameters in
determining success. The purpose of reference systems was to allow NCDOT a second
option in achieving success. The determination of a reference system with its success
criteria would need to be addressed in the mitigation plan. The use of the
hydrogeomorphic system (HGM) was also discussed. The Corps is not going to use
HGM as a reference system. but will probably look at it as a tool. There are no guidelines
out vet on HGM.
The use of 20-80 versus 30-70 probability graphs, as defined.by WETS. way
discussed. These graphs compare the specific year rain data to the historical data for the
mitigation site area. The NRCS and WETS use the 30-70 probability graphs and
NCDOT would like to use these as well. It was decided to use the 30-70 information and
to go to the nearest gage station as long as the source was cited. David determined that if
a site's hydrology performs at 12.5%, then hydrologic success has been achieved. If a
site performs in the 5% to 12.5% range, then there is "marginal" hydrologic success. If
this trend continues, then the entire success criteria for the site will be reviewed.
The target percentage for hydrological success should be included in the permit
' and shown in the mitigation plan. The Corps will be willing to negotiate on the success
of the site, but include adequate information in the permit and the mitigation plan.
' Charles Bruton suggested placing monitoring wells in the impacted wetland areas
to assess and compare to mitigation areas. David wanted to insure that the best
' mitigation site attainable is created. David also asked that well performance be broken
out in the report.
' An interim report was given on Mud Creek. It was noted that wells placed in the
reference wetland and wells placed in the created wetland were an inappropriate method
to determine hydrologic success because the difference in soil type, hydrology, and cover
type.
Mike Bell discussed results of a workshop he attended on monitoring wells. He
also discussed the use of piezometers.

Improvement To SR 1175 (North Kerr Avenue) Bridges

SUBJECT: Revision and Modification To Permit #65-92
Dear Mr. Stroud:
On June 23, 1993, Permit No. 65-92 was issued, by the Department
of Environment Health and Natural`Resources and Coastal Resource
Commission, to the NC Department of Transportation; for Smith
Creek and Spring Branch, at the SR 1175 Crossing in Wilmington.
The Detour at Spring Branch will need to undercut approximately
2.5' below the average ground elevation, per the recommendation
of the Geotechnical Department in Raleigh. This excavation is
needed to maintain a minimum of 3.5' of fill below the subgrade
of the detour, with the.additional strength of fabric placed at
the bottom of the undercut; this should give the roadbed enough
strength to hold the traffic.
I have estimated that this additional excavation will involve
.218 Acres of wetland, and approximately 516 CY of undercut to be
removed and replaced with fill material. Attached is a Plan View
Sheet, showing the location of the undercut; and five (5)
Cross-Section Sheets, showing the depth and width of the undercut
in reference to M.H.T. of 3.1' elevation.

Environmental Unit
Biological report for the proposed
replacement of Bridge # 1 over Spring Branch
on SR 1175 (Kerr,Ave.), New Hanover County,
TIP# B-2059.
The following biological report was completed from ob-
servations and field studies conducted by Environmental Unit
staff on July 5, 1990. Although the project is to be state
funded, it will be processed as a federal Categorical Exclu-
sion (CE). As such, no responses/comments are available from
natural Yesource agencies.
Subject bridge will be replaced on existing location
with a double barrel 11' x 7`' box culvert. During construc-
tion, a temporary detour will route traffic approximately 75
feet east of the existing structure. The temporary detour
will require placement of fill on wetlands adjacent to the
existing alignment for construction of approachways. Three
72 inch diameter corrugated metal pipes (CMP) will be in-
stalled at the temporary crossing of Spring Branch.
The project is located on SR 1175 in New Hanover County
at the eastern Wilmington city limits (Figure 1). Subject
bridge is located in an undeveloped area with commercial and
residential establishments to the north and south of the
project site. Topography in the surrounding areas tends to
be level to gently sloping, typical of floodplains.
PLANT COMMUNITIES
The lowland forested area adjacent to Spring Branch in
the vicinity of the project may be described as a Blackwater AS
Cypress-Gum Swamp community (BC-GSC). This community type is
typically located on floodplains of blackwater rivers which

experience seasonal to semipermanent flooding. Due to the
influence of flooding on 1) water chemistry and 2) alloch-
tonous inputs of organic and inorganic materials, canopy
species diversity tends to be low.
Canopy dominants include Bald Cypress (Taxodium
distichum), Pond Cypress (Taxodium ascendens), and Black Gum
(NVssa biflora). The canopy was dense and transmitted very
little sunlight at the approximate location of the temporary
detour. Several large trees of Loblolly Pine (Pinus taeda),
Water Oak (Ouercus niara), Willow Oak (Ouercus phellos),
Sweetgum (Liquidambar stvraciflua) and Tulip Poplar
(Liriodendron tulipifera) were located on the road shoulder
southeast of the existing bridge. The understory-shrub layer
was dense in spots and sparse in other areas. Predominant
species included Red Bay (Persea borbonia), White Bay
(Magnolia virginiana), Wax Myrtle (Mvrica cerifera), Water
Ash (Fraxinus caroliniana), Tag Alder (Alnus serrulata),
Fetter-bush (Leucothoe racemosa) Titi (Cvrilla racemiflora),
and Loblolly Bay (Gordonia lasianthus). The ground cover was
dominated by a few soft stem aquatic plants such as Pickerel-
weed (Pontederia cordata)Arrow-Head (Sacrittaria sp.
Lizard's Tail (Saururus cernuus).' Cattail (TVpha sp.) and
Royal Fern (Osmunda regalis) were also present. The Obedient
Plant (Dracocephalum Purpureum) was found growing at the edge
of the stream in standing water.
A slight elevation in the northeast corner of the pro-
ject gives rise to another wetland community classified as
Coastal ?lain Bottomland Hardwoods. This community type is
located on slightly higher, drier areas of the floodplain,
away from the main channel. Canopy diversity is usually
greater than the Blackwater4 Cypress-Gum Swamp. This com-
munity tends to have a highly variable flood regime. No
surface water was noted except that associated with small ac-
tive stream channels. Sweetgum (Liquidambar stvraciflua),
Willow Oak (Ouercus phellos), Loblolly Pine ( inus taeda) and
Tulip Poplar (Liriodendron tulipifera) dominated the canopy.
A dense lower strata, the shrub layer, includes Red Maple
(Acer rubrum), Privet (Ligustrum sinense), Tag Alder, Water
Ash and Wax Myrtle. Netted Chain-Fern (Woodwardia areolata),
Cane (Arundinaria aigantea), Cow Itch (Campsis radicans),
Poison Ivy and Catbrier (smilax sp.) dominate the ground
cover.
Anticipated impacts to wetland communities are described
below in the "Wetland" section.
ANIMAL COMMUNITIES
According to Dr. Linquist at the University of North
Carolina at Wilmington (pers. comm.) stream surveys conducted
by researchers approximately 4 years ago indicate the follow-
ing species commonly inhabit Smith Creek: Banded Killifish
(Fundulus diaphanus), Freshwater Goby (Gobionellus
shufledti), Tidewater Silverside (Menidia beryllinia),
Mosquito Fish (Gambusia affinis), Least Killifish
(Heterandria formosa), Mummichog (Fundulus heteroclitus), Red
Breasted sunfish (Lepomis auritis), Fat Sleeper (Dormitator
maculatus), American Eel (Anguilla rostrata), Pirate Perch
(Aphredoderus savanus), Fresh Water Grass Shrimp
(Paleomonetes sp.), Redfin Pickerel (Esox americanus),
Tadpole Madtom (Notorus gvrinus), Swamp Darter
(Etheostoma fusiforme), and Tessalated Darter (Etheostoma
olmsteadi). The Blue Gill (Lepomis macrochirus), and Pumpkin
Seed (L. gibbosus) were not found in the stream surveys but
are common in similar locations nearby. Anadromous fish are
not expected to occur in Spring Branch because it is a small,
shallow tributary.
Mammals that inhabit swamp forests include Gray squir-
rel (Sciurus carolinensis), Cotton Mouse (Peromvscus
gossvpinus), Beaver (Castor canadensis), Raccoon (Procyon
lotor), and Gray Fox (Urocvon cinereoargenteus). occasion-
ally one may find Opossum=(Didelphis virginiana), South-
eastern Shrew (Sorex longirostris), Star-Nosed Mole
(Condvlura cristata), Rafinesques' Big-Eared Bat (Plecotus
rafinesguii), marsh Rabbit (Sylvilagus palustris), Golden
Mouse (Ochrotomvs nuttalli), Rice Rat (Orvzomvs palustris),
Black Bear (Ursus americanus) and White-Tailed Deer
(Odocoileus virginianus).
one-might expect the following amphibians and reptiles
to occur in the project area: Spotted Turtle (Clemmvs
guttata), Rat Snake ( la he obsoleta), Mud Snake (Farancia
abacura), Rainbow Snake (F.'etvtrogramma), Brown Water Snake
(Nerodia taxispilota), Black Swamp Snake (Seminatrix pvgaea)
and Cottonmouth (Agkistrodon piscivorus). A number of
salamanders are likely to inhabit this area including Lesser
Siren (Siren intermedia), Greater Siren (Siren lacertina),
Two-Toed Amphiuma (Amphiuma means), Mabee's Salamander
(Ambvstoma mabeei), Marbled Salamander (Ambvstoma opacum),
southern Dusky Salamander (Desmognathus auriculatus), Two and
Three-Lined Salamanders (Eurvicea bislineata and E.
guttolineata), Dwarf Salamander (Eurvicea guadridigitata), Mud
Salamander (Pseudotriton montanus) and Many-Lined Salamander
(Stereochilus marginatus). One could also expect a variety
of frogs including Gray Treefrog (H a versicolor), Green
Treefrog (H. cinerea), Barking Treefrog (H. gratiosa), Little
Grass Frog (Limnaoedus ocularis), Brimley's Chorus Frog
(Pseudacris brimlevi), ornate Chorus Frog (P. ornata), River
Frog (Rana heckscheri) and Southern Leopard Frog (R.
sphenocephala).
Avian fauna common to swamp forests include the Great
Blue Heron (Ardea herodias), Wood Duck (Aix sponsa), Turkey
Vulture (Cathartes aura), Red-Shouldered Hawk (Buteo
lineatus), Barred Owl (Strix varia), Pileated Woodpecker
(Drvocopus pileatus), Red-Bellied Woodpecker (Melanerpes
carolinus), Northern Parula (Parula americana) and Prothonary
and Yellow Throated Warblers (Protonotaria citrea and
Dendroica dominica).
Benthic information is not available for the area. No
sampling sites are established near the project site.
Construction along Spring Branch will disturb aquatic
communities in two sections, one along the temporary detour
and the other at the site of bridge replacement. One effect
construction will have on aquatic systems is siltation. Sil-
tation can effect water chemistry, resulting in changes to
the pH and oxygen demand. Potential impacts to sessile, ben-,,
thic communities and fish species are anticipated. Immobile
organisms such as mollusks, will be more severely impacted.
Sensitive species may either be reduced in numbers or elimi-
nated where changes in water quality are severe. In general,
heavy siltation will adversely effect the diversity of the
aquatic biota in this stream. It is important that such im-
pacts be minimized by strict coherence to "Best Management
Practices" and sediment control policies.
The temporary detour (an elevated causeway) may also
form a barrier to terrestrial animals. During seasonal mi-
gration patterns, animals normally accustomed to the tempo-
rary use of foraging habitat in the project area, may be
denied such access. Endemic species which follow diurnal
patterns of movement throughout the project area may find
that avenues of access are no longer available due to site
modifications. Impacts are likely to be more severely felt
by some species than others.. Subterranean, burrowing species
are examples of relatively immobile animals that would re-
ceive direct impacts by the proposed actions. Reduction in
populations of certain species would result in the establish-
ment of asymmetric community compositions, a fact that would
likely influence behavioral patterns and interspecies rela-
tionships like competition and predator-prey interactions.
For example, if a predator's favorite species is displaced by
the proposed action, it is likely that 1) it may displace it-
self by searching for prey outside of the area, or 2) it may
begin to seek out other species as potential prey.
WETLANDS
Two types of wetland impacts are anticipated from
project construction. "Permanent" impacts are expected from
bridge construction activities in the vicinity of the exist-
ing bridge. Spring Branch and surrounding plant communities
will be impacted from bridge replacement activities and ap-
proach work. The approach work will impact a narrow strip
along the existing roadway.
"Temporary" impacts are anticipated from the placement
and subsequent removal of the temporary detour. Grubbing of
existing vegetation and excavation of native hydric soils are
anticipated prior to placement of roadbed fill. Subsoil com-
paction from construction equipment is also anticipated.
Permanent bridge construction includes shoulder work on the
existing roadway on both sides adjacent to and in conjunction
with the temporary detour.
The following estimates of anticipated wetland impacts
are based on a 60 feet impact widths:
Wetland Impacts
Permanent Temporary
0.15 0.58
(Figure.2)
Since less than one acre of wetlands will be impacted,
the Nationwide Permit Provisions of 33 CFR 330.5 (a) are
likely to be applicable. Permitting in wetlands will fall
under the jurisdiction of=the US Army Corps of Engineers and
State Division of Coastal Management (DCM).
SOILS
Dorovan Soils are mapped in the vicinity of Spring
Branch according to the New Hanover Soil Survey. These soils
are classified as hydric. The Dorovan series consists of
very poorly drained, very slowly permeable soils typically
found in stream floodplains. Slopes are less than one per-
cent. These soils are frequently flooded for long periods.
Seagate Fine Sands are mapped at the north end of the
project. Seagate Fine Sands are classified as soils with
hydric inclusions. The Seagate series is somewhat poorly
drained, moderately permeable soil located on nearly level
uplands. Slopes are generally less than two percent.
WATER RESOURCES
Spring Branch is assigned a best usage classification of
"C SW". Class C waters are suitable for aquatic life propa-
gation and survival, fishing, wildlife, secondary recreation
and agriculture. Swamp Waters (Sw) have low velocities and
other characteristics such as low pH and low dissolved oxygen
levels which differ from non-swamp waters.
In accordance with the provisions of the Coastal Area
Management Act (LAMA) DCM designated Spring Branch as a
"Public Trust Area of Environmental Concern" (AEC) under
"Inland" jurisdiction. Public Trust AEC's are critical areas
that fall under CAMA developmental guidelines. They are wa-
ters and submerged lands where the public has the right of
use and/or ownership, including right of navigation and re-
creation. Public Trust Areas limit development in two ways;
1) by maintaining navigation pathways and 2) by maintaining
stream flow. Piping in the temporary detour should accom-
modate adequate stream velocities as well as stream flow
during bridge construction.
Spring Branch, a tributary of Smith Creek, is under
minimal tidal influence. Tide flow can result in the in-
troduction of inorganic salts, but, perhaps more impor-
tantly, can bring about water level variations of several
feet, especially during special lunar tides and heavy rains.
Spring Branch is neither a Primary Nursery Area nor a
Secondary Nursery Area. Primary Nursery Areas are those in
the estuarine system where initial post-larval development
takes place; Secondary Nursery Areas are areas where later
juvenile development takes place.
Also, Spring Branch is also not designated a "Natural _
and Scenic River" (state) nor a "Wild and Scenic River"
(federal government). Classification in either category
would place proposed action under additional developmental
guidelines.
If stream rechannelization of Spring Branch is
necessary, NCDOT will need to consult with the NC Wildlife
Resources Commission and DEM (LAMA).
RARE/ENDANGERED SPECIES
.r
r
The American Alligator (Alligator mississippiensis),
which has a state and federal status of "Threatened" is list-
ed in the Natural Heritage Program files as occurring down-
stream of the project area. It is classified as "Threatened
due to similarity of appearance" to other reptiles such as
the American crocodile, which makes it prone to exploitation
and therefore, extinction. This status was assigned as a
means of protecting the American Crocodile in areas where the
two species' ranges overlap. The American Crocodile does not
occur in North Carolina but the Alligator's range extends
into the state and is afforded legal protection throughout
its range. The American Alligator was not observed during
field observations. No impacts to rare or endangered flora
or fauna are anticipated.
MITIGATION
"Best Management Practices" should be followed during
construction. Erosion should be prevented to reduce silta-

tion downstream. Also, provisions should be made to allow
adequate water flow under both the subject bridge and tempo-
rary detour by using the correct size and placement of cul-
verts and pipes especially for high water contingencies.
Roadbed fill should be minimized in wetland areas, especially
along the temporary detour. Vegetation removal should be re-
stricted along the detour and rapid revegetation should be
encouraged after project completion. Impacted Blackwater
Cypress-Gum Swamp and Coastal Plain Bottomland Hardwood Swamp
Forest wetland communities should be restored to original
condition after removal of the temporary detour, including
restoration of substrate porosity.

MEMORANDUM TO: Wayne Elliott, Unit Head
Bridge Replacement Unit
FROM: Susan Corda, Environmental Biologist ?- &dc'
Environmental Unit
SUBJECT: Biological Survey of the proposed
replacement of Bridge # 2 over Smith Creek
on SR 1175 (Kerr Ave.), New Hanover County,
TIP## B-2156.
The following biological survey was completed from
observations and field studies conducted by Environmental
Unit staff on July 5, 1990. Although the project will be
state fuhded, it will be processed as a federal Categorical
Exclusion (CE). No responses/comments are available from
natural resource agencies.
x
Subject bridge will be replaced on new location approxi-
mately 50 feet west of the existing bridge. The new align-
ment will eliminate the sharp curvature of the roadway.
Bridge construction length of 120 feet and width of 36 feet
are proposed. During construction of the bridge and
approaches, traffic will be maintained on the existing struc-
ture. After construction is completed the existing structure
will be removed.
The project is located on SR 1175 in New Hanover County
at the eastern Wilmington city limits (Figure 1). Area
surrounding the project site is residential to the south (a
trailer park) and to the east (a housing development).
Topography in the project impact area ranges from nearly
level to gentle slopes associated with floodplains.
PLANT COMMUNITIES
A Blackwater Cypress-Gum swamp is found in the Smith
Creek project area. This community occurs along floodplains

of blackwater rivers and has a highly variable flow regime.
The water tends to be very acidic, low in mineral sediment,
low in nutrients and colored by tannins. Smith Creek is un-
der irregular freshwater tidal influence.
A few disturbances are noted in the project area. A
utility line crosses the Cypress-Gum Swamp community west of
Kerr Road. Vegetation is dense in areas outside the utility
corridor, in contrast with maintained, low growing vegetation
along the utility line. The canopy is not full along the new
roadway for another reason-the presence of stream channels
and small tributaries, that meander through the area, and
dissect the canopy. Canopy dominants include bald cypress
(Taxodium distichum), Water Oak (Ouercus niara), water Ash
(Fraxinus caroliniana) and Sweetg_um (Liauidambar
stvraciflua). The sapling/shrub layer is dense with Privet
(Ligustrum sinense), Tag Alder (Alnus serrulata), Red Maple
(Acer rubrum), wax Myrtle (Mvrica cerifera) and Marsh Elder
(Iva frutescens). Wisteria (Wisteria sp.) and woody grape
(Vitis sp.) vines are common. Ground cover species includes
Ludwigia (Ludwigia sp.), Rush (Jungus sp.), Water-Hemlock
(Cicuta maculata) and Dodder (Cusctta sp.).
A disturbed hardwood/pine community exists on a small
wetland "island" between the utility line and the existing
roadway on the south side of Smith Creek. This community has
attributes of a Coastal Plain Bottomland Hardwoods community,
but plant composition has been influenced by disturbance.
Canopy dominants include Loblolly Pine,(Pinus taeda),
Sycamore-(Platanus occidentalis), Sweetgum (Liauidambar
stvraciflua) and Red Maple. Privet, and Tulip Poplar
(Liriodendron tulipifera) are major elements of the under-
story. The ground cover is-Icomposed of a mixture of plants
including Ebony Spleenwort (Asplenium platvneuron), Bedstraw
(Galium sp.), and clover. Vines such as Wisteria, Honey-
suckle (Lonicera Japonica), and Grape (Vitis sp.) are very
prolific.
Several herbaceous plants are typically found along the
north side of Smith Creek in areas with little elevation
change. These plants occur in full sun at breaks in the
canopy. Pickerel Weed (Pontederia cordata), Arrow-Head
(Sagittaria sp.), Pigweed (Amaranthus sp.), Cattail (Tvpha
sp.), Sensitive Fern (Onoclea sensibilis) and Alligator Weed
(Alternanthera philoxeroides) dominate these areas.
Upland communities occur in scattered locations along
the proposed alignment. South of Smith Creek is a small
upland site with sparse vegetation due to patterns of heavy
vehicular and foot traffic. The second upland site lies
north of the creek on a small mound at the site of a utility
pole. Both sites have been disturbed by man. Dominant plant
species in these locations are Sweetgum, Tulip Poplar,
Loblolly Pine, Beauty Berry (Callicarpa americana) and Cane
r
(Arundinaria aigantea).
Impacts to upland plant communities include removal of
vegetation along the new alignment, reducing and fragmenting
available habitat. vegetation will be removed and soils
compacted by construction equipment. These impacts may be
long term.
Wetland impacts are described below in the "Wetlands"
section.
ANIMAL COMMUNITIES
According to Dr, Linquist at the University of North
Carolina at Wilmington (pers. comm.), stream surveys
conducted by researchers approximately 4 years ago list the
following aquatic species in Smith Creek: Banded Killifish
(Fundulus diaphanus), Freshwater Goby (Gobionellus
shufledti), Tidewater Silverside (Menidia bervllinia),
Mosquito Fish (Gambusia affinis), Least Killifish
(Heterandria formosa), Mummichog (Fundulus heteroclitus), Red
Breasted Sunfish (Lepomis auritis), Fat Sleeper (Dormitator
maculatus), American Eel (Anguilla rostrata), Pirate Perch
(Aphredoderus sayanus), Fresh Water Grass Shrimp
(Paleomonetes sp.), Redfin Pickerel (Esox americanus)
Tadpole Madtom (Notorus gyrinus), Swamp Darter
(Etheostoma fusiforme), and Tessalated Darter (Etheostoma
olmsteadi). The Blue Gill (Lepomis macrochirus), and Pumpkin
Seed (L..gibbosus) were not found during stream surveys, but
are common in similar locations nearby. Anadromous fish are
not expected to occur in Smith Creek because it is too
shallow.
Mammals that inhabit swamp forests include Gray
Squirrel (Sciurus carolinensis), Cotton Mouse (Peromyscus
Qossvpinus), Beaver (Castor canadensis), Raccoon (Procyon
lotor), and Gray Fox (Urocyon cinereoaraenteus). Occa-
sionally one may find Opossum (Didelphis virainiana), South-
eastern Shrew (Sorex longirostris), Star-Nosed Mole
(Condvlura cristata), Rafinesques' Big-Eared Bat (Plecotus
rafinesquii), Marsh Rabbit (Sylvilaaus palustris), Golden
Mouse (Ochrotomvs nuttalli), Rice Rat (Orvzomys palustris),
Black Bear (Ursus americanus) and White-Tailed Deer
(Odocoileus virainianus).
one might expect the following amphibians and reptiles
to occur in the project area: Spotted Turtle (Clemmys
guttata), Rat Snake ( la he obsoleta), Mud Snake (Farancia
abacura), Rainbow Snake (F. etvtroaramma), Brown Water Snake
(Nerodia taxispilota), Black Swamp Snake (Seminatrix Pygaea)
and Cottonmouth (Aakistrodon piscivorus). A number of
salamanders are likely to inhabit this area including Lesser
Siren (Siren intermedia), Greater Siren (Siren lacertina),
It
Two-Toed Amphiuma (Amphiuma means), Mabee's Salamander
(Ambvstoma mabeei), Marbled Salamander (Ambvstoma opacum),
Southern Dusky Salamander (Desmoanathus auriculatus), Two and
Three-Lined Salamanders (Eurvicea bislineata and E.
auttolineata), Dwarf Salamander (Eurvicea guadridiaitata), Mud
Salamander (Pseudotriton montanus) and Many-Lined Salamander
(Stereochilus marainatus). One could also expect a variety
of frogs including Gray Treefrog (Hula versicolor), Green
Treefrog (H. cinerea) and Barking Treefrog (H. aratiosa),
Little Grass Frog (Limnaoedus ocularis), Brimley's Chorus
Frog (Pseudacris brimlevi), ornate Chorus Frog (P. ornata),
River Frog (Rana heckscheri) and southern Leopard Frog (R.
sphenocephala).
Avian fauna common to swamp forests include the Great
Blue Heron (Ardea herodias), Wood Duck (Aix sponsa), Turkey
Vulture (Cathartes aura), Red-Shouldered Hawk (Buteo
lineatus), Barred Owl (Strix varia), Pileated Woodpecker
(Drvocopus pileatus), Red-Bellied Woodpecker (Melanerpes
carolinus), Northern Parula (Paru americana) and Prothonary
and Yellow Throated Warblers (Protonotaria citrea and
Dendroica dominica). ,
Benthic information is not available for the area. No
sampling sites are established near the project site.
One effect construction will have on aquatic systems is
siltation. Siltation can effect the water chemistry by
changing pH and oxygen demand. Potential impacts to sessile,
benthic and fish communities are anticipated. Sessile
organisms such as mollusks, will be more severely impacted,
while mobile organisms such as fish, are more apt to migrate
to other areas. Sensitive aquatic species will either be
reduced in numbers or eliminated due to a change in water
quality. In general, heavy siltation may adversely effect
the diversity of the aquatic biota in this stream. The new
bridge is expected to span Smith Creek for 120 feet to avoid
conflicts with wetland areas. Any prospective impacts should
be minimized by strict adherence to "Best Management
Practices" and sedimentation control policies.
The new bridge alignment may also form a barrier to
terrestrial animals. During seasonal migration patterns
animals normally accustomed to the temporary use of foraging
habitat in the project area, may be denied such access.
Endemic species which follow diurnal patterns of movement
throughout the project area may find that avenues of access
are no longer available due to site modifications. Impacts
are likely to be more severely felt by some species than
others. Subterranean, burrowing species are examples of
relatively immobile animals that would receive direct impacts
by the proposed actions. Reduction in populations of certain
species would result in the establishment of asymmetric
community compositions, a fact that would likely influence
y ? ?r
behavioral patterns and interspecies relationships like com-
petition and predator-prey interactions. For example, if a
predator's favorite species is displaced by the proposed ac-
tion, it is likely that 1) it may displace it-self by search-
ing for prey outside of the area, or 2) it may begin to seek
out other species as potential prey.
Removal of the old bridge should, in effect, open up new
terrestrial and aquatic habitat at Smith Creek. Such action
is likely to mitigate, in part, the loss of habitat from
construction of the new facility.
WETLANDS
Permanent impacts to wetlands are anticipated from con-
struction on new location. Grubbing of existing vegetation
and excavation of native hydric soils are anticipated prior
to placement of roadbed fill. Subsoil compaction from .
construction equipment is also anticipated. Bridge construc-
tion on new location will further fragment the swamp forest
plant community.
Wetland impacts are anticipated from bridge construction
on new location. The following wetland acreages will be im-
pacted from construction (Acreage estimates are based on 60
feet impact widths):
Tidal Cypress-Gum Swamp 0.5 acres
(Figure 2)
Smith Creek is designated a "Public Trust Area of Envi-
ronmental Concern" (AEC) under "Inland" jurisdiction by the
Coastal Area Management Act (CAMA). Public Trust AEC's are
waters and submerged lands in the coastal region where the
public has the right of use or ownership, including the right
of navigation and recreation. The Public Trust Areas
designation limits development in two ways: 1) by maintaining
navigation pathways and 2) by maintaining stream flow.
Bridge construction over Smith Creek should allow adequate
stream flow during construction and final design should
accommodate adequate stream velocities. In addition to a
Public Trust Area, streamside zones along Smith Creek are
considered Coastal Wetlands. The presence of Cattail in
areas of the proposed project clearly defines these areas as
Coastal Wetlands AEC's.
The second LAMA regulation concerns development in an
area that is dominated by one or more plants in CAMA's list
of plant species common to wetland areas. "Cattail" is
listed as one of the plants that fall in CAMA's jurisdiction.
As such, wetland development in this area requires a permit
from the Division of Coastal Management (DCM). Permitting
?, ti
for wetland development along Smith Creek will fall under the
jurisdiction of the US Army Corps of Engineers and the State
Division of Coastal Management.
SOILS
Dorovan Soils are mapped in the vicinity of Smith Creek
according to the New Hanover Soil Survey. These soils are
classified as hydric according to the Soil Conservation
Service. The Dorovan series consists of very poorly drained,
very slowly permeable soils typically found in stream flood-
plains. Slopes are less than one percent. These soils are
frequently flooded for long periods.
Seagate Fine Sands are mapped at the north end of the
project in the vicinity of the trailer park. Seagate Fine
Sands are classified as soils with'hydric inclusions. The
Seagate series is somewhat poorly drained, moderately perme-
able soil located on nearly level uplands. Slopes are
generally less than two percent.
The upland mound along the utility line is underlain by
soils different than the two series listed above, based upon
the color comparisons. Soils in this area are not thought to
naturally occur at this site and were not classified.
WATER RESOURCES
Smith Creek is classified as C Sw. Class C waters are
suitable for aquatic life propagation and survival, fishing,
secondary recreation and agriculture. Swamp Waters (Sw) have
low velocities and other characteristics such as low pH and
low dissolved oxygen levels that often differ from non-swamp
streams.
Smith Creek is under tidal influence which can cause the
waters to become brackish at times. Also, water level can
change a few feet or more during high tides (especially lunar
tides) and heavy rains. Development along Smith Creek falls
under CAMA guidelines. CAMA regulations are discussed in the
"Wetlands" section above. If stream rechannelization of
Smith Creek is necessary, NCDOT will need to consult with the
NC Wildlife Resources Commission and DCM.
Smith Creek is neither a Primary Nursery Area nor a
Secondary Nursery Area at this location. Primary Nursery
areas are those in the estuarine system where post-larval
development takes place; secondary are those areas where
later juvenile development takes place. Populations are
usually composed of organisms which have migrated from an
upstream Primary Nursery Area to the Secondary Nursery Area.
Smith Creek is also not a designated "Natural and Scenic
River" (state) nor a "Wild and Scenic River" (federal
government). Classification within either category would
place proposed action under additional developmental
guidelines.
RARE/ENDANGERED SPECIES
The American Alligator (Alligator mississippiensis),
which has a state and federal status of "Threatened" is list-
ed in the Natural Heritage Program files as occurring down-
stream of the project area. Its technical classification is
"Threatened due to similarity of appearance". This status
was assigned as a means of protecting the American Crocodile
in areas where the two species' ranges overlap. Although the
American Crocodile does not occur.in North Carolina, the
Alligator's range does extend into the state; therefore
is afforded legal protection in our area. The Alligator was
not observed during field observations. No impacts to rare
or endangered flora or fauna are anticipated.
MITIGATION
"Best Management Practices" should be followed during
construction. Erosion should be prevented or reduced as much
as possible to reduce siltation downstream. Also, provisions
should be made to allow adequate water flow under the new
bridge by using the correct size and placement of culverts
and pipes especially for high water contingencies. Roadbed
fill should be minimized in wetland areas. Vegetation re-
moval should be restricted -And rapid re-vegetation encouraged
after project completion. Impacted plant communities should
be restored to original condition after removal of the exist-
ing roadway, including restoration of substrate porosity.

Dear Sir:
DIVISION OF HIGHWAYS
WILLIAM G. MARLEY, JR., P.E.
STATE HIGHWAY ADMINISTRATOR
SUBJECT: New Hanover County, Replacement of Bridge No. 1 over
Spring Branch and Bridge No. 2 over Smith creek on
SR 1175 (B-2059, B-2156, 6.503228).
The North Carolina Department of Transportation (NCDOT)
intends to replace the above-mentioned bridges on North Kerr
Avenue (SR 1175). These bridges must be replaced due to their
deteriorated condition and unsafe design. This activity will
require minor impacts to wetland communities at the project
site. t
. The bridge over Spring Branch is designated as Site 1 in
this permit application. NCDOT proposes to construct a
temporary detour west of the roadway to maintain traffic.
The existing bridge will be replaced by a new structure
approximately 90 feet long and 40 feet wide. The new bridge
and improved roadway will provide 24 feet of pavement and 8
feet of useable shoulder on both sides. This will require
the placement of 300 cubic yards of fill below ordinary high
water in 0.3 acres of wetlands.
The bridge over Smith Creek, designated as Site 2 is
currently in a badly skewed position. NCDOT proposes to
relocate this bridge to the west, with new approaches. The
new structure will be about 120 feet long and 40 feet wide,
providing 24 feet of pavement and 8 foot shoulders. This
will require placement of 800 cubic yards of fill in 0.4
acres of wetlands. The existing bridge and roadway will be
used to maintain traffic during construction, and will then
be removed to natural grade.
An Equal Opportunity/Affirmative Action Employer

On February 6, 1990, the Department of the Army and the
U.S. Environmental Protection Agency signed a Memorandum of
Agreement (MOA) which established procedures for determining
the type and level of mitigation required for projects with
wetland impacts. This MOA requires: utilization of the least
damaging, practicable alternative, minimization of the
project impacts, and development of a mitigation plan for
unavoidable impacts. The following information is provided
to demonstrate compliance with these procedures.
NCDOT believes that this proposal uses the least
damaging, practicable alternative. One factor in this
decision is the need to maintain traffic on North Kerr Avenue
during construction. North Kerr Avenue is designated as a
major thoroughfare in the Wilmington Thoroughfare Plan.
Current traffic volume in the vicinity of the subject bridges
is 7,000 vehicles per day. A suitable,detour route for this
level of traffic is unavailable. Consequently, the temporary
detour at site 1 is necessary to maintain traffic.
A more important concern is that the existing roadway is
very unsafe due to a generally poor alignment and the skew in
the bridge over Smith Creek. Between 1983 and 1990, at least
31 accidents have been reported in the project vicinity,
involving several fatalities. This is an unusually high and
unacceptable number of accidents. Since most of these
accidents involved drivers who lost control in the curve, the
obvious solution is to straighten the alignment. This
necessitates the relocation of the roadway.and bridge to the
west.
All standard procedures will. be implemented to further
avoid and minimize environmental'Eimpacts. This will include
all NCDOT best management practices, which your agency has
reviewed. NCDOT also intends to mitigate for those wetland
impacts which cannot be avoided, a projected total of 0.7
acres. Upon project completion, the existing roadway at
Smith Creek will be removed to natural grade, and the area
planted in appropriate vegetation (see attached mitigation
guidelines). This will restore approximately 0.2 acres of
wetlands. The temporary detour will also be removed and
planted according to the guidelines.
Under current guidance, restoration activities generate
mitigation credits on a 2 acres restored to 1 acre impacted
basis. Accordingly, restoration of 0.2 acres at Smith Creek
will generate 0.1 acres of credit. This leaves 0.6 acres of
mitigation credit to be generated elsewhere. It is proposed
that these remaining impacts be debited from the Company
Swamp Mitigation Bank. As you are aware, the agreements for
this bank provide for debiting impacts less than 5 acres in
size on a 1:1 basis. Accordingly, 0.6 acres of credit will
be debited from the gum/cypress habitat credits remaining in
the bank.
K--- . --?,
Randy Henegar, of NCDOT's Hydraulics Unit, has met with
Robert Stroud of your Division to discuss this project at the
site. NCDOT has attempted to comply with the concerns
expressed by Mr. Stroud during preparation of this
application. NCDOT hereby applies for the CAMA Major
Development permit as required for this project. The U.S.
Army Corps of Engineers notified us by letter dated February
11, 1991 that this project will be processed as a
categorical Exclusion persuant to 23 CFR 771.115(b) (copy of
letter attached). A copy of this application is being
provided to them for their information.

DMINISTRATOR
SUBJECT: New Hanover County, Replacement of Bridge No. 1 over
Spring Branch and Bridge No. 2 over Smith creek on
SR 1175 (B-2059, B-2156, 6.503228).
The North Carolina Department of Transportation (NCDOT)
intends to replace the above-mentioned bridges on North Kerr
Avenue (SR 1175). These bridges must be replaced due to their
deteriorated condition and unsafe design. This activity will
require minor impacts to wetland communities at the project
site.
The bridge over Spring Branch is designated as Site 1 in
this permit application. NCDOT proposes to construct a
temporary detour west of the roadway to maintain traffic.
The existing bridge will be replaced by a new structure
approximately 90 feet long and 40 feet wide. The new bridge
and improved roadway will provide 24 feet of pavement and 8
feet of useable shoulder on both sides. This will require
the placement of 300 cubic yards of fill below ordinary high
water in 0.3 acres of wetlands.
The bridge over Smith Creek, designated as site 2 is
currently in a badly skewed position. NCDOT proposes to
relocate this bridge to the west., with new approaches. The
new structure will be about 120 feet long and 40 feet wide,-.
providing 24 feet of pavement and 8 foot shoulders. This
will require placement of 800 cubic yards of fill in 0.4
acres of wetlands. The existing bridge and roadway will be
used to maintain traffic during construction, and will then
be removed to natural grade.
An Eoual ODoortunlty/Affirmative Action Emolover

On February 6, 1990, the Department of the Army and the
U.S. Environmental Protection Agency signed a Memorandum of
Agreement (MOA) which established procedures for determining
the type and level of mitigation required for projects with
wetland impacts. This MOA requires: utilization of the least
damaging, practicable alternative, minimization of the
project impacts, and development of a mitigation plan for
unavoidable impacts. The following information is provided
to demonstrate compliance with these procedures.
NCDOT believes that this proposal uses the least
damaging, practicable alternative. One factor in this
decision is the need to maintain traffic on North Kerr Avenue
during construction. North Kerr Avenue is designated as a
major thoroughfare in the Wilmington Thoroughfare Plan.
Current traffic volume in the vicinity of the subject bridges
is 7,000 vehicles per day. A suitable detour route for this
level of traffic is unavailable. Consequently, the temporary
detour at site 1 is necessary to maintain traffic.
A more important concern is that the existing roadway is
very unsafe due to a generally poor alignment and the skew in
the bridge over Smith Creek. Between 1983 and 1990, at least
31 accidents have been reported in the project vicinity,
involving several fatalities. This is an unusually high and
unacceptable number of accidents. Since most of these
accidents involved drivers who lost control in the curve, the
obvious solution is to straighten the alignment. This
necessitates the relocation of the roadway and bridge to the
west.
All standard procedures will be implemented to further
avoid and minimize environmental impacts. This will include
all NCDOT best management practices, which your agency has
reviewed. NCDOT also intends to mitigate for those wetland
impacts which cannot be avoided, a projected total of 0.7
acres. Upon project completion, the existing roadway at
Smith Creek will be removed to natural grade, and the area
planted in appropriate vegetation (see attached mitigation
guidelines). This will restore approximately 0.2 acres of
wetlands. The temporary detour will also be removed and
planted according to the guidelines.
Under current guidance, restoration activities generate
mitigation credits on a 2 acres restored to 1 acre impacted
basis. Accordingly, restoration of 0.2 acres at Smith Creek
will generate 0.1 acres of credit. This leaves 0.6 acres of
mitigation credit to be generated elsewhere. It is proposed
that these remaining impacts.be debited from the Company
Swamp Mitigation Bank. As you are aware, the agreements for
this bank provide for debiting impacts less than 5 acres in
size on a 1:1 basis. Accordingly, 0.6 acres of credit will
be debited from the gum/cypress habitat credits remaining in
the bank.

9. PROJECT DESCRIPTION - Continued:
downstream side will have approximately 500' of 8' wide fill
placed into the wetlands. The upstream side will have
approximately 463' of 8' wide fill. The difference in the length
of fill on this side is a result of the presence of 2 existing
driveways. Approximately 165' of 8' to 10' wide class "I" rip
rap will be used to stabilize the new bridge approaches. The
area under the detour and temporary channel will be restored upon
completion of this phase of the project.
At site 2 the applicants are proposing to replace the existing
bridge within a new alignment in order to remove the existing
dangerous curve associated with the existing structure. The
structure will consist of three (3) - 42' bride spans each 40'
wide. The southern approach will originate from high ground.
The northern approach will be created partially by the placement
of fill in wetlands. Approximately 360' of fill varying in width
from 0' to 90' will be constructed on the downstream side of
existing road bed. Approximately 230' of fill, up to 15' wide
will be used in the upstream side wetlands. The total roadbed
feature will average approximately 80' wide. The existing creek
will be widened under the bridge site approximately 20' for a
distance of approximately 120' in order to improve flow dynamics.
Approximately 160' of Class "I" rip-rap varying in width from 10'
to 40' will be utilized to stabilize the banks of the approaches
adjacent to the bridge sites. Approximately 50' linear feet 15'
side will be used in a curve of the bank downstream to prevent
the scour of the new approach fill in that location.
Approximately 280' of existing road bed averaging 30' wide will
be removed to existing adjacent wetland elevation.
10. ANTICIPATED IMPACTS
Smith Creek represents a very real threat to public safety with
the existing road alignment and poor existing bridge design.
Spring Branch requires upgrading also. Approximately 0.7 acres
of freshwater wetlands will be consumed by the proposed action at
both sites. The Spring Branch bridge will involve a permanent
loss of 0.3 acres and the Smith Creek site will result in a net
loss of 0.2 acres even though the initial impact will involve 0.4
acres due to the necessary re-alignment in order to ensure a safe
roadway. The proposed restoration at the Smith Creek site will
result in approximately 0.2 acres of wetlands. Based on the 2:1
mitigation formula this 0.2 acres will account for only 0.1 acres
of the 0.7 acres. The other 0.6 acres will be accounted for
utilizing the Company Swamp Mitigation Bank. Based on current
agreements all impacts less that 5 acres will be debited from the
gum\cypress habitat credits remaining in the Company Swamp Bank.
The applicants are also proposing restoration guidelines
including the planting of hardwoods. (copy enclosed)

IV. Success Criteria
* Survival rate of 32 stems per 0.1 acre (320 per acre)
V. Results (See Wetland Mitigation Report - Vegetation, for more information)
No monitoring plots were established. However, site inspection revealed that no trees
could be located on the site. The site is thriving well as a brackish (tidal) marsh with a
dense stand of Juncus and Spartina sp..
VI. Summary
Areas on both bridges under old bridge approaches were graded to natural grade and
planted with appropriate species. There were no plots established. By visual observation,
we determined that none of the trees planted have survived. Colonization of marsh
species is beginning throughout the site due to adjacent marsh habitat.
VII. Proposed Remedial Action
The site will be replanted with the same species during March 1997.

bridge) continues to grow well at this time with a mixture of Black Willow, Bald
Cypress, Tulip Poplar, Black Gum, Juncus, Giant Cordgrass, and Cattails. Site 2 (west
side of bridge) also continues grow well with a predominant mixture of Bald Cypress and
Black Gum, along with some Wax Myrtle, Alder, and Pine on the higher elevations at the
bottom of the fill slope.
l
VI. Summary
Areas on both bridges under old bridge approaches were graded to natural grade and
planted with appropriate species. There were no plots established. By visual observation
we obtained that there are greater than 32 stems per 0.1 acre on both planted sites.
Naturalizing of marsh is continuing throughout the site due to adjacent marsh habitat.

Smith Creek will be removed to natural grade, and the area
planted in appropriate vegetation (see attached mitigation
guidelines). This will restore approximately 0.2 acres of
wetlands. The temporary detour will also be removed and
planted according to the guidelines.
Under current guidance, restoration activities generate
mitigation credits on a 2 acres restored to 1 acre impacted
basis. Accordingly, restoration of 0.2 acres at Smith Creek
will generate 0.1 acres of credit. This leaves 0.6 acres of
mitigation credit to be generated elsewhere. It is proposed
that these remaining impacts be debited from the Company
Swamp Mitigation Bank. As you are aware, the agreements for
this bank provide for debiting impacts less than 5 acres in
size on a 1:1 basis. Accordingly, 0.6 acres of credit will
be debited from the gum/cypress habitat credits remaining in
the bank.
Randy Henegar, of NCDOT's Hydraulics Unit, has met with
Robert Stroud of your Division to discuss this project at the
site. NCDOT has attempted to comply with the concerns
expressed by Mr. Stroud during preparation of this
application. NCDOT hereby applies for the CAMA Major
Development permit as required for this project. The U.S.
Army Corps of Engineers notified us by letter dated February
11, 1991 that this project will be processed as a
Categorical Exclusion persuant to 23 CFR 771.115(b) (copy of
letter attached). A copy of this application is being
provided to them for their information.
If you need any additional information, please call
Gordon Cashin at [phone].

NC DOT - DOH
Bridge #1 Spring Branch
Bridge #2 Smith Creek

9. PROJECT.DESCRIPTION
The project sites consist of the two existing bridge crossings on
S.R. 1175 over two streams off the N. E. Cape Fear River. Site
one (1) is identified as the Spring Branch crossing. Site two (2)
is identified as the Smith Creek Crossing. Spring Branch is a
tidal stream and is a tributary of Smith Creek. It is
approximately 20' wide at this segment of the stream. The
existing bridge is approximately 40' long x 26' wide. The travel
way in this area is approximately 24' wide. The approaches on
either side are approximately 45' wide. Spring Branch is
classified as C SW and is considered to be Inland waters. The
wetlands associated with Spring Branch are of the freshwater
variety. Cypress, Pine, Black Gum, Green Ash and Alder are
present along the downstream area along with herbaceous emergent
species. On the upstream side of the road and bridge are found
Black Gum, Tulip Poplar, Red Maple, Bald Cypress, Water Oak,and
Pine. Smith Creek is a larger stream located approximately 1/4
mile north of Spring Branch. The creek is approximately 651wide
downstream of the existing bridge and approximately 40' wide
under the existing bridge. This structure is approximately 80'
long x 24' wide. The existing road bed is approximately 45' to
50' wide at the approaches. Smith Creek is also classified as C
SW and is designated as Inland waters. The wetlands associated
with the upstream side of Smith Creek are Green Ash, Black Gum,
Bald Cypress, Alder, Red Maple, Water Oak and Tulip Poplar. There
are also unidentified emergent herbaceous species present. These
include two small colonies of narrow leafed cat-tail. There-is
the distinct possibility that anadramous fish use both steams
during certain flow periods.
The applicants propose to remove the existing bridge at site 1
and replace it with a new structure comprised of three (3) 30'
structures each 40' wide. In order to complete the work it will
be necessary to construct a temporary detour. This detour will
be placed over the existing channel of Spring Branch. The length
of this feature will be approximately 390' and the maximum width
will be approximately 601. The natural channel will be directed
to a created channel approximately 120' long x 20' wide (top
width). This flow in this feature will be conveyed under the
detour through 2 - 84" CSP to empty into the natural stream bed.
The natural channel turns sharply to the south just east of the
existing bridge and road bed. It follows down the bank of the
existing fill approach for approximately 2101. This alignment
threatens the existing bank. The applicants propose to reshape
the bank creating a 10' shelf and relocate this channel to a 10'
bottom width. This work will occur approximately 25' east of the
existing toe of bank. On the southern approach, on the
downstream side the banks will be filled for an additional 120'
approximately 5' into the wetlands. On the north approach the
NC DOT - DOH
Bridge #1 Spring Branch
Bridge #2 Smith Creek

9. PROJECT DESCRIPTION - Continued:
downstream side will have approximately 500' of 8' wide fill
placed into the wetlands: The upstream side will have
approximately 463' of 8' wide fill. The difference in the length
of fill on this side is a result of the presence of 2 existing
driveways. Approximately 165' of 8' to 10' wide class "I" rip
rap will be used to stabilize the new bridge approaches. The
area under the detour and temporary channel will be restored upon
completion of this phase of the project.
At site 2 the applicants are proposing to replace the existing
bridge within a new alignment in order to remove the existing
dangerous curve associated with the existing structure. The
structure will consist of three (3) - 42' bride spans each 40'
wide. The southern approach will originate from high ground.
The northern approach will be created partially by the placement
of fill in wetlands. Approximately 360' of fill varying in width
from 0' to 90' will be constructed on the downstream side of
existing road bed. Approximately 230' of fill, up to 15' wide
will be used in the upstream side wetlands. The total roadbed
feature will average approximately 80' wide. The existing creek
will be widened under the bridge site approximately 20' for a
distance of approximately 120' in order to improve flow dynamics.
Approximately 160' of Class "I" rip-rap varying in width from 10'
to 40' will be utilized to stabilize the banks of the approaches
adjacent to the bridge sites. Approximately 50' linear feet 15'
side will be used in a curve of the bank downstream to prevent
the scour of the new approach fill in that location.
Approximately 280' of existing road bed averaging 30' wide will
be removed to existing adjacent wetland elevation.
10. ANTICIPATED IMPACTS
Smith Creek represents a very real threat to public safety with
the existing road alignment and poor existing bridge design.
Spring Branch requires upgrading also. Approximately 0.7 acres
of freshwater wetlands will be consumed by the proposed action at
both sites. The Spring Branch bridge will involve a permanent
loss of 0.3 acres and the Smith Creek site will result in a net
loss of 0.2 acres even though the initial impact will involve 0.4
acres due to the necessary re-alignment in order to ensure a safe
roadway. The proposed restoration at the Smith Creek site will
result in approximately 0.2 acres of wetlands. Based on the 2:1
mitigation formula this 0.2 acres will account for only 0.1 acres
of the 0.7 acres. The other 0.6 acres will be accounted for
utilizing the Company Swamp Mitigation Bank. Based on current
agreements all impacts less that 5 acres will be debited from the
gum\cypress habitat credits remaining in the Company Swamp Bank.
The applicants are also proposing restoration guidelines
including the planting of hardwoods. (copy enclosed)

10. ANTICIPATED IMPACTS - Continued:
This project as proposed (especially the Smith Creek portion)
appears to have overriding public benefits which compensate for
the wetland losses. The Corps (see attached letter) has
designated this project as a categorical exclusion and has
authorized the action.

9. PROJECT DESCRIPTION
The project sites consist of the two existing bridge crossings on
S.R. 1175 over two streams off the N. E. Cape Fear River. Site
one (1) is identified as the Spring Branch crossing. Site two (2)
is identified as the Smith Creek Crossing. Spring Branch is a
tidal stream and is a tributary of Smith Creek. It is
approximately 20' wide at this segment of the stream. The
existing bridge is approximately 40' long x 26' wide. The travel
way in this area is approximately 24' wide. The approaches on
either side are approximately 45' wide. Spring Branch is
classified as C SW and is considered to be Inland waters. The
wetlands associated with Spring Branch are of the freshwater
variety. Cypress, Pine, Black Gum, Green Ash and Alder are
present along the downstream area along with herbaceous emergent
species. On the upstream side of the road and bridge are found
Black Gum, Tulip Poplar, Red Maple, Bald Cypress, Water Oak,and
Pine. Smith Creek is a larger stream located approximately 1/4
mile north of Spring Branch. The creek is approximately 651wide
downstream of the existing bridge and approximately 40' wide
under the existing bridge. This structure is approximately 80'
long x 24' wide. The existing road bed is approximately 45' to
50' wide at the approaches. Smith Creek is also classified as C
SW and is designated as Inland waters. The wetlands associated
with the upstream side of Smith Creek are Green Ash, Black Gum,
Bald Cypress, Alder, Red Maple, Water Oak and Tulip Poplar. There
are also unidentified emergent herbaceous species present. These
include two small colonies of narrow leafed cat-tail. There is
the distinct possibility that anadramous fish use both steams
during certain flow periods.
The applicants propose to remove the existing bridge at site 1
and replace it with a new structure comprised of three (3) 30'
structures each 40' wide. In order to complete the work it will
be necessary to construct a temporary detour. This detour will
be placed over the existing channel of Spring Branch. The length
of this feature will be approximately 390' and the maximum width
will be approximately 601. The natural channel will be directed
to a created channel approximately 120' long x 20' wide (top
width). This flow in this feature will be conveyed under the
detour through 2 - 84" CSP to empty into the natural stream bed.
The natural channel turns sharply to the south just east of the
existing bridge and road bed. It follows down the bank of the
existing fill approach for approximately 2101. This alignment
threatens the existing bank. The applicants propose to reshape
the bank creating a 10' shelf and relocate this channel to a 10'
bottom width. This work will occur approximately 25' east of the
existing toe of bank. On the southern approach, on the
downstream side the banks will be filled for an additional 120'
approximately 5' into the wetlands. On the north approach the

Bridge #1 Spring Branch
Bridge #2 Smith Creek

9. PROJECT DESCRIPTION - Continued:
downstream side will have approximately 500' of 8' wide fill
placed into the wetlands. The upstream side will have
approximately 463' of 8' wide fill. The difference in the length
of fill on this side is a result of the presence of 2 existing
driveways. Approximately 165' of 8' to 10' wide class "Ill rip
rap will be used to stabilize the new bridge approaches. The
area under the detour and temporary channel will be restored upon
completion of this phase of the project.
At site 2 the applicants are proposing to replace the existing
bridge within a new alignment in order to remove the existing
dangerous curve associated with the existing structure. The
structure will consist of three (3) - 42' bride spans each 40'
wide. The southern approach will originate from high ground.
The northern approach will be created partially by the placement
of fill in wetlands. Approximately 360' of fill varying in width
from 0' to 90' will be constructed on the downstream side of
existing road bed. Approximately 230' of fill, up to 15' wide
will be used in the upstream side wetlands. The total roadbed
feature will average approximately 80' wide. The existing creek
will be widened under the bridge site approximately 20' for a
distance of approximately 120' in order to improve flow dynamics.
Approximately 160' of Class "I" rip-rap varying in width from 10'
to 40' will be utilized to stabilize the banks of the approaches
adjacent to the bridge sites. Approximately 50' linear feet 15'
side will be used in a curve of the bank downstream to prevent
the scour of the new approach fill in that location.
Approximately 280' of existing road bed averaging 30' wide will
be removed to existing adjacent wetland elevation.
10. ANTICIPATED IMPACTS
Smith Creek represents a very real threat to public safety with
the existing road alignment and poor existing bridge design.
Spring Branch requires upgrading also. Approximately 0.7 acres
of freshwater,wetlands will be consumed by the proposed action at
both sites. The Spring Branch bridge will involve a permanent
loss of 0.3 acres and the Smith Creek site will result in a net
loss of 0.2 acres even though the initial impact will involve 0.4
acres due to the necessary re-alignment in order to ensure a safe
roadway. The proposed restoration at the Smith Creek site will
result in approximately 0.2 acres of wetlands. Based on the 2:1
mitigation formula this 0.2 acres will account for only 0.1 acres
of the 0.7 acres. The other 0.6 acres will be accounted for
utilizing the Company Swamp Mitigation Bank. Based on current
agreements all impacts less that 5 acres will be debited from the
gum\cypress habitat credits remaining in the Company Swamp Bank.
The applicants are also proposing restoration guidelines
including the planting of hardwoods. (copy enclosed)

10. ANTICIPATED IMPACTS - Continued:
This project as proposed (especially the Smith Creek portion)
appears to have overriding public benefits which compensate for
the wetland losses. The Corps (see attached letter) has
designated this project as a categorical exclusion and has
authorized the action.

INISTRATOR
SUBJECT: New Hanover County, Replacement of Bridge No. 1 over
Spring Branch and Bridge No. 2 over Smith Creek on
SR 1175 (B-2059, B-2156, 6.503228).
The North Carolina Department of Transportation (NCDOT)
intends to replace the above-mentioned bridges on North Kerr
Avenue (SR 1175). These bridges must be replaced due to their
deteriorated condition and unsafe design. This activity will
require minor impacts to wetland communities at the project
site.
The bridge over Spring Branch is designated as Site 1 in
this permit application. NCDOT proposes to construct a
temporary detour west of the roadway to maintain traffic.
The existing bridge will be replaced by a new structure
approximately 90 feet long and 40 feet wide. The new bridge
and improved roadway will provide 24 feet of pavement and 8
feet of useable shoulder on both sides. This will require
the placement of 300 cubic yards of fill below ordinary high
water in 0.3 acres of wetlands.
The bridge over Smith Creek, designated as Site 2 is
currently in a badly skewed position. NCDOT proposes to
relocate this bridge to the west, with new approaches. The
new structure will be about 120 feet long and 40 feet wide,
providing 24 feet of pavement and 8 foot shoulders. This
will require placement of 800 cubic yards of fill in 0.4
acres of wetlands. The existing bridge and roadway will be
used to maintain traffic during construction, and will then
be removed to natural grade.
An Equal Opportunity/Affirmative Action Employer

On February 6, 1990, the Department of the Army and the
U.S. Environmental Protection Agency signed a Memorandum of
Agreement (MOA) which established procedures for determining
the type and level of mitigation required for projects with
wetland impacts. This MOA requires: utilization of the least
damaging, practicable alternative, minimization of the
project impacts, and development of a mitigation plan for
unavoidable impacts. The following information is provided
to demonstrate compliance with these procedures.
NCDOT believes that this proposal uses the least
damaging, practicable alternative. One factor in this
decision is the need to maintain traffic on North Kerr Avenue
during construction. North Kerr Avenue is designated as a
major thoroughfare in the Wilmington Thoroughfare Plan.
Current traffic volume in the vicinity of the subject bridges
is 7,000 vehicles per day. A suitable detour route for this
level of traffic is unavailable. Consequently, the temporary
detour at Site 1 is necessary to maintain traffic.
A more important concern is that the existing roadway is
very unsafe due to a generally poor alignment and the skew in
the bridge over Smith Creek. Between 1983 and 1990, at least
31 accidents have been reported in the project vicinity,
involving several fatalities. This is an unusually high and
unacceptable number of accidents. Since most of these
accidents involved drivers who lost control in the curve, the
obvious solution is to straighten the alignment. This
necessitates the relocation of the roadway and bridge to the
west.
All standard procedures will be implemented to further
avoid and minimize environmental impacts. This will include
all NCDOT best management practices, which your agency has
reviewed. NCDOT also intends to mitigate for those wetland
impacts which cannot be avoided, a projected total of 0.7
acres. Upon project completion, the existing roadway at
Smith Creek will be removed to natural grade, and the area
planted in appropriate vegetation (see attached mitigation
guidelines). This will restore approximately 0.2 acres of
wetlands. The temporary detour will also be removed and
planted according to the guidelines.
Under current guidance, restoration activities generate
mitigation credits on a 2 acres restored to 1 acre impacted
basis. Accordingly, restoration of 0.2 acres at Smith Creek
will generate 0.1 acres of credit. This leaves 0.6 acres of
mitigation credit to be generated elsewhere. It is proposed
that these remaining impacts be debited from the Company
Swamp Mitigation Bank. As you are aware, the agreements for
this bank provide for debiting impacts less than 5 acres in
size on a 1:1 basis. Accordingly, 0.6 acres of credit will
be debited from the gum/cypress habitat credits remaining in
the bank.

Randy Henegar, of NCDOT's Hydraulics Unit, has met with
Robert Stroud of your Division to discuss this project at the
site. NCDOT has attempted to comply with the concerns
expressed by Mr. Stroud during preparation of this
application. NCDOT hereby applies for the CAMA Major
Development permit as required for this project. The U.S.
Army Corps of Engineers notified us by letter dated February
11, 1991 that this project will be processed as a
Categorical Exclusion persuant to 23 CFR 771.115(b) (copy of
letter attached). A copy of this application is being
provided to them for their information.
