SUBJECT: Catawba County, Replacement of Bridge No. 94 over McLin Creek
on SR 1722; Federal Aid Project No. BRZ-1722(1); State Project
No. 8.2791601; TIP No. B-2941.
Attached for your information is a copy of the project planning document for the
subject project prepared by the North Carolina Department of Transportation (DOT) and
signed by the Federal Highway Administration (FHWA) on October 31, 1996. The
project involves replacing Bridge No. 94 over McLin Creek on SR 1722. The new bridge
will be placed on existing alignment. During project construction, traffic will be
maintained using an on-site detour located south of the existing structure. No
jurisdictional wetlands will be impacted by the subject project.
The project is being processed by the FHWA as a "Categorical Exclusion" (CE) in
accordance with 23 CFR 771.115(b). Therefore, we do not anticipate requesting an
individual permit but propose to proceed under a Nationwide Permit 23 in accordance
with 33 CFR 330 Appendix A (B-23) issued December 13, 1996, by the Corps of
Engineers (COE). The provisions of Section 330.4 and Appendix A (C) of these
regulations will be followed in the construction of the project.
The DOT anticipates that 401 Ggn?ra)Hth r Quality Certification for an approved
CE will apply to this project. A copy of oe ument has also been provided to the
North Carolina Department of Environm 1lt, and Natur al Resources, Division of
Water Quality, for their review.-

SR 1722
Bridge No. 94 Over McLin Creek
Catawba County
Federal-Aid Project No. BRZ-1722(1)
State Project No. 8.2791601
T.I.P. No. B-2941
Bridge No. 94 is included in the North Carolina Department of Transportation 1997-2003
Transportation Improvement Program. The location is shown in Figure 1. No substantial
impacts are anticipated as a result of this action. The project is classed as a Federal
"Categorical Exclusion."
1. SUMMARY OF ENVIRONMENTAL COMMITMENTS
1. All Standard procedures and measures, including NCDOT's Best Management
Practices for Protection of Surface Waters, will be implemented, as applicable, to avoid
or minimize environmental impacts.
2. The temporary detour approach fills will be removed to pre-construction contour and
revegetated.
3. Location and installation of any required deck drains will be determined during final
design phase
II. SUMMARY OF RECOMMENDATIONS
Bridge No. 94 will be replaced on existing alignment with a new bridge 44 meters (145 ft) in
length and 9.2 meters (30 ft) in width (Figure 2). The resulting roadway surface on the bridge
will accommodate a 7.2 meter (24 ft) travelway with 1.0 meter (3 ft) shoulders on each side.
The roadway grade at the bridge will be approximately the same elevation as the existing
structure. Traffic will be maintained on-site with a temporary detour on the south side during the
construction period.
The estimated cost, based on current prices, is $915,500 including $40,500 for right-of-way and
$875,000 for construction. The estimated cost of the project, as shown in the 1997-2003
Transportation Improvement Program, is $325,000 including $25,000 for right-of-way and
$300,000 for construction.

III. EXISTING CONDITIONS
SR 1722 is functionally classified as a rural minor collector. Land use in the project area is
predominantly residential and agricultural. Bridge No. 94 is located within the City Limits of
the small town of Catawba, 0.2 miles west of the junction with SR 1968.
Near the bridge, SR 1722 has a 5.5 meter (18 ft) paved travel width with 2.1 meter (7 ft)
shoulders. The bridge is approximately 60 m. (200 ft.) east of a 350 m. (5 degree) radius curve
and approximately 215 m (700 ft.) west of a 295 m. (6 degree) radius curve. The roadway is
approximately 5.2 meters (17 ft.) above the creek bed.
The projected traffic volume is 1700 vehicles per day (vpd) for 1997 and 3200 vpd for the
design year 2017. The volumes include one percent truck-tractor semi-trailer (TTST) and two
percent dual-tired vehicles (DT). The speed limit is posted 70 km/h (45 mph) at the project site.
The existing bridge was built in 1956 (Figure 3). The superstructure consists of three spans of
reinforced concrete deck with steel 1-beams on reinforced concrete abutments.
The overall length of the bridge is 31.3 meters (103 ft), consisting of three spans: 1 @ 8.5
meters (28 ft), 1 @ 14.3 meters (47 ft), and 1 @ 8,5 meters (28 ft). The clear roadway width is
7.6 meters (25 ft). The posted weight limit is 10.89 metric tons (12 tons) for single vehicles and
13.62 metric tons (15 tons) for truck tractor semi-trailers.
Bridge No. 94 has a sufficiency rating of 20.4, compared to a rating of 100 for a new structure.
This low rating warrants replacement of the bridge.
Southern Railroad's arched bridge is approximately 22.9 meters (75 ft) north of Bridge No. 94.
According to the Catawba County Planning Department, there is a 12 inch water line on the
north side of the bridge below existing grade. A 15 inch sewer line was observed downstream
from the bridge on the north side of the railroad tracks during the investigation. Overhead
powerlines are on the north and south side of the bridge. The powerline on the north side of the
bridge crosses SR 1722 east of the bridge. An overhead telephone line is on the south side of
the bridge. Utility impacts are anticipated to be low.
Six accidents were reported in the vicinity of the bridge during the period from April 1, 1992 to
March 31, 1995. Three accidents occurred in the curve east of the bridge and two accidents
occurred in the curve west of the bridge. The one accident that occurred on the bridge was
due to icy conditions.
Ten Catawba County school busses cross Bridge No. 94 daily.

IV. ALTERNATIVES
No relocation alignments were considered for replacement of the existing bridge. As shown by
the plan review (Figure 2), the existing roadway provides the best alignment possible.
Bridge No. 94 will be replaced with a new bridge 44 meters (145 ft) in length and 9.2 meters (30
ft) in width. The resulting roadway surface on the bridge will accommodate a 7.2 meter (24 ft)
travelway with 1.0 meter (3 ft) shoulders on each side.
Traffic will be maintained by constructing a temporary on-site detour south of the existing bridge.
The temporary detour bridge will be approximately 32 meters (105 ft) in length. Due to the
relatively high volume of traffic generated by industry to the east of Bridge No. 94, the 12.9
kilometer (8 mi.) off-site detour route is not economically feasible. Utilizing an off-site detour will
create hardships for school buses using SR 1722.
The "do-nothing" alternative would eventually necessitate closure of the bridge. This is not
desirable due to the traffic service provided by SR 1722.
Investigation of the existing structure by the Bridge Maintenance Unit indicates the rehabilitation
of the old bridge is not feasible due to its age and deteriorated condition.
V. ESTIMATED COST
The estimated costs, based on current prices, are as follows:
(Recommended)
Structure Removal (existing) $ 15,810
Structure (proposed) 283,360
Roadway approaches 96,630
Temp. Detour Structure and Approaches 183,500
Miscellaneous and Mobilization 170,700
Engineering and Contingencies 125,000
ROW/Const. Easements/Utilities 40,500
TOTAL $915,500
VI. RECOMMENDED IMPROVEMENTS
Bridge No. 94 over McLin Creek will be replaced on existing location. Traffic will be maintain
by a temporary on-site detour south of the existing bridge (Figure 2).
The proposed roadway over the bridge will provide a 7.2 meter (24 ft) travel way with 1.0 meter
(3 ft) shoulders.
The Division Engineer concurs in the recommendation that the bridge be replaced at the
existing location with a temporary on-site detour on the southern side.
Based on a preliminary hydraulic analysis utilizing the 25 year design storm, the new structure is
recommended to have a length of approximately 44 meters (145 ft.). The elevation of the new
structure will be approximately the same as the existing bridge. The replacement structure will
maintain a minimum 0.3% grade to facilitate deck drainage. The length and height may be
increased or decreased as necessary to accommodate peak flows as determined by further
hydrologic studies.
VII. NATURAL RESOURCES
The proposed project lies in Catawba County (Figure 1) in a rural area west of Catawba, North
Carolina within the Piedmont Physiographic Province. Catawba County is primarily agricultural
but is rapidly becoming an industrial and urban county.
Methodology
Informational sources used to prepare this report include: United States Geological Survey
(USGS) quadrangle map (Catawba, 1970); NCDOT aerial photographs of project area (1:1200);
Soil Conservation Service (SCS) soil maps (1975); Fish and Wildlife Service (FWS) National
Wetlands Inventory Map (Catawba, 1994); FWS list of protected species and federal species of
concern (1996); and North Carolina Natural Heritage Programs (NCNHP) database of
uncommon species and unique habitats. Research using these resources was conducted prior
to the field investigation.
A general field survey was conducted along the proposed project corridor on March 20, 1996.
Plant communities and their associated wildlife were identified using a variety of observation
techniques, including active searching, visual observations with binoculars, and identifying
characteristic signs of wildlife (sounds, tracks, scats, and burrows).
Quantitative impact calculations were based on the worst case scenario using the full 24.4 m
(80.0 ft) wide right-of-way limits, the width of the stream for aquatic impacts, and the length of
the project approaches. The actual construction impacts should be less, but without speck
replacement structure design information (culvert, pier intrusions, etc.) the worst case was
assumed for the impact calculations.
Definitions for area descriptions used in this report are as follows: "project study area", "project
area", and "project corridor" denote the area being directly impacted by each alternative.
"Project vicinity" denotes the area within a 1.6 km (1.0 mi.) radius of the project area.
Topography and Soils
The topography of the project area is characterized as rolling hills with steeper slopes along the
major streams. Project area elevation is approximately 237.7 m (780.0 ft).
This portion of Catawba County contains soils from the Hiwassee-Cecil association, which are
characterized as being gently sloping to moderately steep soils that have a subsoil that is
dominantly dark-red or red, firm clay found on broad ridgetops and short side slopes. The field
investigation confirms the soils as they are mapped.

WATER RESOURCES
This section describes each water resource and its relationship to major water systems. The
proposed project lies within the Catawba River drainage basin.
Water Resource Characteristics
McLin Creek is a perennial tributary within the Catawba River basin. The stream banks are well
defined, approximately 3.0 m (10.0 ft) high, and vegetated with river birch, greenbrier, and
Japanese honeysuckle. Within the project area McLin Creek is approximately 15.8 m (52.0 ft)
wide. The stream flows southwest to northeast through the proposed project area with a width
at the bridge of 18.0 m (60.0 ft). The stream was approximately four to five feet deep on the
day of the investigation. The stream was turbid and the bottom was not visible. McLin Creek
has a Class WS-IV rating and stream index no. 11-76-5(3) from the North Carolina Division of
Environmental Management (NCDEM). This best usage classification is generally assigned to
surface waters used as sources of water supply for drinking, culinary or food processing
purposes. These waters are suitable for all Class C uses. Class C uses include aquatic life
propagation and survival, fishing, wildlife, secondary recreation, and agriculture. The set of
more stringent erosion control rules under the NC Sedimentation Pollution Control Act that apply
within WS I and WS II watershed do not apply to land disturbing activities in WS IV watersheds.
The Federal Emergency Management Agency (FEMA) Flood Boundary and Floodway Map for
Catawba County (1980) indicates the project area lies in Zone A7 where base flood elevations
and flood hazard factors have been determined. The base flood elevation at Bridge No. 94 is
238.4 m (782.0 ft).
The NCDEM does not maintain a fish or macroi nverteb rate sampling station on McLin Creek
within or near the project area; however, McLin Creek flows into Lyle Creek which does have a
sampling station. Benthic macro-invertebrates, or benthos, are organisms that live in and on
the bottom substrates of rivers and streams. The use of benthos data has proven to be a
reliable tool as some benthic macroinvertebrates are sensitive to subtle changes in water
quality. Criteria have been developed to assign bioclassifications ranging from "Poor" to
"Excellent" to each benthic sample based on the number of taxa present in the intolerant groups
Ephemeroptera, Plecoptera and Trichoptera 8 (EPT). Different criteria have been developed for
different ecoregions (mountains, piedmont, coastal) within North Carolina. Data from Lyle
Creek at US 64/70 in August 1992 indicated an EPT taxa richness value of 22 which is a
bioclassification of "Good".
The NCDEM also uses the North Carolina Index of Biotic Integrity (NCIBI) as another method to
determine general water quality. The method was developed for assessing a stream's
biological integrity by examining the structure and health of its fish communities. The scores
derived from the index are a measure of the ecological health of the waterbody and may not
necessarily directly correlate to water quality. Data from Lyle Creek at US 64170 in November
1993 indicated a NCIBI score of 52, which was an integrity class of "Good".
The Catawba County Watershed Protection District Ordinance (1993) provides regulations to
limit the exposure of watersheds in Catawba County to pollution. The Critical Area is defined as
being one-half mile from a lake or where water is taken from a river. The critical area is the area
closest to a drinking water source. Therefore, the regulations restrict development in this area.
5
The Protected Area is the remainder of the watershed where the regulations apply. The
Watershed Protection District Map indicates that the project area is not within a Critical Area.
No waters classed by NCDEM as High Quality Waters (HQW), Outstanding Resource Waters
(ORW), or waters designated as WS-1 or WS-11 are located within 1.6 km (1.0 mile) of the
project study area. No impacts to sensitive water resources of any kind will take place as a
result of the project construction.
Anticipated Impacts to Water Resources
Short-term impacts to water quality can be anticipated from construction-related activities, which
may increase sedimentation and turbidity. Short-term impacts will be minimized by the
implementation of NCDOT's Best Management Practices for Protection of Surface Waters, as
applicable. Long-term impacts to water resources are not expected as a result of proposed
improvements.
BIOTIC RESOURCES
Living systems described in the following sections include communities of associated plants and
animals. These descriptions refer to the dominant flora and fauna in each community and the
relationship of these biotic components. Scientific nomenclature and common names (when
applicable) are used for the plant and animal species described. Subsequent references to the
same species include the common name only.
Terrestrial Communities
The predominant terrestrial communities found in the project study area are man-dominated
and successional mixed hardwood forest. Dominant faunal components associated with these
terrestrial areas will be discussed under the community description. Many species are adapted
to the entire range of habitats found along the project alignment, but may not be mentioned
separately in each community description.
Man-Dominated Community
This highly disturbed community includes the road shoulders, the powerline easement, and the
area adjacent to the railroad (Figure 2). Many plant species are adapted to these disturbed and
regularly maintained areas. The roadsides are dominated by fescue (Festuca sp.), ryegrass
(Lolium sp.), wild onion (Allium canadense), birdfoot violet (Viola pedata), henbit (Lamium
amplexicaule), vetch (Vicia sp.), and dandelion (Taraxacum officinale). The area along the
railroad and the powerline easement are dominated by the above species as well as kudzu
(Pueraria lobata), blackberry (Rubus sp.), Japanese honeysuckle (Lonicera japonica), tree-of-
heaven (Ailanthus altissima), and some river birch (Betula nigra) saplings.
The animal species present in these disturbed habitats are opportunistic and capable of
surviving on a variety of resources, ranging from vegetation (flowers, leaves, fruits, and seeds)
to both living and dead faunal components. Although not observed during the site visit, the
Virginia opossum (Didelphis virginiana), several species of mice (Peromyscus sp.), Northern
cardinal (Cardinalis cardinalis), American crow (Corvus brachyrhynchos), and the American
robin (Turdus migratodus) are often attracted to these roadside and disturbed habitats.
6
Successional Mixed Hardwood Community
This forested community occurs along McLin Creek upstream from the bridge. The dominant
canopy trees on the east side of the creek include river birch, tulip poplar (Liriodendron
tulipifera), American sycamore (Platanus occidentalis), and sweetgum (Liquidambar styraciflua).
An understory of ironwood (Carpinus caroliniana) and willow oak (Quencus phellos) are also
found in this community. The shrub layer is dominated by privet (Ligustrum sinense), and the
herbaceous layer consists mainly of Japanese honeysuckle, bedstraw (Galium sp.), common
greenbrier (Smilax rotundifolia), poison ivy (Toxicodendron radicans), and kudzu. The west side
of the creek is dominated by river birch, tulip poplar, kudzu, Japanese honeysuckle, and
greenbrier as well as a planted pine (pinus sp.) area.
Although only a downy woodpecker (Picoides pubescens), a Carolina wren (Thryothorus
ludovicianus), and a gray squirrel (Sciurus carolinensis) were observed during the site visit,
other animals previously listed may be found in this community along with the raccoon (Procyon
lotor), the mourning dove (Zenaida macroura), and the Eastern box turtle (Terrapene carolina
carolina).
Aquatic Communities
The aquatic community in the project area exists within McLin Creek. On the day of
investigation the stream was turbid and the bottom was not visible.
Animals such as the belted kingfisher (Megaceryle alcyon), the bullfrog (Rana catesbeiana),
and the snapping turtle (Chelydra serpentina) may reside along the waters edge. Due to the
large size and depth of McLin Creek, macroinvertebrates such as mayfly (Ephemeroptera),
stonefly (Plecoptera), and caddisfly (Trichoptera) larvae are confined to the shallow rocky areas
and snag habitats along the creek banks. The macroinvertebrate fauna within the channel
would be dominated by chironimid larvae (midges) and oligochaetes (segmented worms).
According to the North Carolina Wildlife Resources Commission, in a memorandum dated April
10, 1996, (see appendix) the following fish species were collected in McLin Creek in 1991:
common carp (Cyprinus carpio), rosyside dace (Clinostomus funduloides), bluehead chub
(Nocomis leptocephalus), greenhead shiner (Notropis chlorocephalus), creek chub (Semotilus
atromaculatus), white sucker (Catostomus commersoni), silver (v-lip) redhorse (Moxostoma
anisurum), striped jumprock (Moxostoma rupiscartes), channel catfish (Ictalurus punctatus),
redbreast sunfish (Lepomis auritus), bluegill (Lepomis macrochirus), fantail darter (Etheostoma
flabellare), and tessellated darter (Etheostoma olmstedi).
Anticipated Impacts to Biotic Communities
Biotic community impacts resulting from project construction are addressed separately as
terrestrial impacts and aquatic impacts. Table 1 details the anticipated impacts to terrestrial and
aquatic communities by habitat type. However, impacts to terrestrial communities, particularly in
locations exhibiting steep slopes, can result in the aquatic community receiving heavy sediment
loads as a consequence of erosion. Efforts will be made to ensure that no sediment leaves the
construction site.

Terrestrial Communities
Of the two terrestrial communities in the project area, the man-dominated community will
receive the greatest impact from construction, resulting in the loss of existing habitats and
displacement and mortality of faunal species in residence.
Aquatic Communities
The aquatic community in the study area exists within McLin Creek. The proposed bridge
replacement may result in the disturbance of up to 0.04 hectare (0.10 acre) of stream bottom.
This represents "worst case" condition; actual area of disturbance should be considerably less.
Construction of the bridge and roadway approaches will likely increase sediment loads in the
stream in the short term. Construction related sedimentation can be harmful to local
populations of invertebrates which are an important part of the aquatic food chain. Potential
adverse effects will be minimized through the implementation of NCDOTs Best Management
Practices for Protection of Surface Waters, as applicable, and the use of erosion and sediment
control measures as specified in NCDOT Erosion and Sedimentation Control Guidelines for
Contract Construction (January 1995)'.
SPECIAL TOPICS
Jurisdictional Issues
Waters of the United States
Wetlands and surface waters fall under the broad category of "Waters of the United States" as
defined in 33 CFR 328.3 and in accordance with provisions of Section 404 of the Clean Water
Act (33 U.S.C. 1344) and are regulated by the United States Army Corps of Engineers
(USACOE).
8
Impacts to Wetlands and Surface Waters
No wetlands will be impacted by the subject project as McLin Creek has well defined banks
within the bridge replacement corridor. Investigation into wetland occurrence in the project area
was conducted using methods of the 1987 Wetland Delineation Manual. Project construction
cannot be accomplished without infringing on jurisdictional surface waters. Anticipated surface
water impacts fall under the jurisdiction of the USACOE. Up to 0.04 hectare (0.10 acre) of
jurisdictional surface water impacts may occur due to the proposed replacement of Bridge No.
94.
Permits
A Nationwide Permit No. 33 CFR 330.5(a)(23) is likely to be applicable for all impacts to Waters
of the United States from the proposed project. This permit authorizes activities undertaken,
assisted, authorized, regulated, funded or financed in whole, or part, by another Federal agency
or department where:
1) that agency or department has determined the pursuant to the council on environmental
quality regulation for implementing the procedural provisions of the National
Environmental Policy Act;
2) that the activity, work, or discharge is categorically excluded from environmental
documentation because it is included within a category of actions which neither
individually nor cumulatively have a significant effect on the human environment, and;
3) that the office of the Chief of Engineers has been furnished notice to the agency's or
department's application for the categorical exclusion and concurs with that
determination.
The NCWRC made several potential recommendations pertaining to the permit application for
this project in an April 10, 1996 memorandum (see Appendix). These recommendations, as
applicable, will be implemented in accordance with the NCDOT's Best Management Practices
for Protection of Surface Waters.
Mitigation
Compensatory mitigation is not proposed due to the limited nature of this project's impact,
however, mitigation requirements on projects covered by Nationwide permits remains at the
discretion of the USACOE.
Rare and Protected Species
Some populations of plants and animals are in the process of decline either due to natural
forces or due to their inability to coexist with man. Rare and protected species listed for
Catawba County, and any likely impacts to these species as a result of the proposed project
construction, are discussed in the following sections.
9
Federally Protected Species
Plants and animals with federal classification of Endangered (E), Threatened (T), Proposed
Endangered (PE) and Proposed Threatened (PT) are protected under provisions of Section 7
and Section 9 of the Endangered Species Act of 1973, as amended. The USFWS lists one
federally protected species for Catawba County as of August 23, 1996, (see Table 2).

and approximately 4.0 to 6.0 cm (1.6 to 2.4 inches) long and wide. The flowers have a
cylindrical calyx tube with an apical flare which is wider than the calyx tube is long. The flowers
are present between late March and June.
The dwarf-flowered heartleaf is often found in mature, deciduous forests on acidic, sandy loam
soils of north facing bluffs and ravines. It is frequently associated with mountain laurel, and with
Pacolet sandy loam soil of the Piedmont physiographic province.
No habitat exists for the dwarf-flowered
deciduous forests on north facing slopes.

BIOLOGICAL CONCLUSION: NO EFFECT
Federal Species of Concern
Federal Species of Concern (FSC) are not legally protected under the Endangered Species Act
and are not subject to any of its provisions, including Section 7, until they are formally proposed
or listed as Threatened of Endangered. Species designated as FSC are defined as taxa which
may or may not be listed in the future. These species were formerly Candidate 2 (C2) species,
or species under consideration for listing for which there is insufficient information to support
listing. NCNHP database showed no recorded occurrences of state protected species within
the project vicinity.
10
Table 3 includes FSC species listed for Catawba County and their state classifications.

FEDERAL SPECIES OF CONCERN
CATAWBA COUNTY
Scientific Name North Carolina Habitat
(Common Name) Status Present
Dactyloctythere isabelae N/L No
(Catawba crayfish ostracod)
Monotropsis odorata C Yes
(Sweet pinesap)
NOTES: C Denotes Candidate species which are considered by the State as being rare and needing
population monitoring.
N/L Denotes species for which the state status is not listed at this time.
State Protected Species
Plant and animals which are listed as Endangered (E), Threatened (T), or Special Concern
(SC) by the NCNHP list of Rare Plant and Animal species are afforded limited state protection
under the State Endangered Species Act and the North Carolina Plant Protection and
Conservation Act of 1979.
The NCNHP records indicated two state-listed Special Concern species, highfin carpsucker
(Carpiodes velifer and loggerhead shrike (Lanius ludovicianus ludovicianus). A search of the
NCNHP database showed no recorded occurrences of state protected species within the
project vicinity and no individuals were observed during the investigation.
VIII. CULTURAL RESOURCES
This project is subject to compliance with Section 106 of the National Historical Preservation
Act of 1966, as amended, implemented by the Advisory Council on Historic Preservation's
Regulations for Compliance with Section 106, coded at 36 CFR Part 800. Section 106
requires that for federally funded, licensed, or permitted projects having an effect on properties
listed in or eligible for the National Register of Historic Places, the Advisory Council on Historic
Preservation be given the opportunity to comment.
The SHPO, in a memorandum dated April 4, 1996, stated that there are no known
archaeological sites in the area and it is unlikely that any archaeological resources eligible for
inclusion in the National Register of Historic Places will be affected by the project construction
and therefore recommends that "no archeological investigation be conducted in connection
with this project. A copy of the SHPO memorandum is included in the Appendix.
In a concurrence form dated April 11, 1996, the State Historic Preservation Officer (SHPO)
concurred that there are no historic architectural resources either listed in or eligible for listing in
11
the National Register of Historic Places located in the project's area of potential effect. A copy
of the concurrence form is included in the Appendix.
IX. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact. Replacement of an inadequate
bridge will result in safer traffic operations.
The bridge replacement will not have an adverse effect on the quality of the human or natural
environment with the use of current NCDOT standards and specifications.
The project is not in conflict with any plan, existing land use, or zoning regulation. No significant
change in land use is expected to result from construction of the project.
No adverse impact on families or communities is anticipated. No relocatees are expected with
implementation of the proposed alternatives.
No adverse effect on public facilities or services is anticipated. The project is not expected to
adversely affect social, economic, or religious opportunities in the area.
There are no publicly owned parks, recreational facilities, or wildlife and waterfowl refuges of
national, state, or local significance in the vicinity of the project.
No geodetic survey markers will be impacted.
Since the bridge will be replaced at its existing location the Farmland Protection Policy Act does
not apply.
This project is an air quality "neutral" project, so it is not required to be included the regional
emission analysis (if applicable) and a project level CO analysis is not required.
This project is located in Catawba County, which has been determined to be in compliance with
the National Ambient Air Quality Standards. 40 CFR Part 51 is not applicable, because the
proposed project is located in an attainment area. This project is not anticipated to create any
adverse effects on the air quality of this attainment area.
The traffic volumes will not increase or decrease because of this project. There are no
receptors located in the immediate project area. The project's impact on noise and air quality
will not be significant.
Noise levels could increase during construction but will be temporary. If vegetation is disposed
of by burning, all burning shall be done in accordance with applicable local laws and regulations
of the North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520. This evaluation
completes the assessment requirements for highway traffic noise (23 CFR Part 772) and for air
quality (1990 CAAA and NEPA) and no additional reports are required.
An examination of records at the North Carolina Department of Environment, Health and
Natural Resources, Division of Environmental Management, Groundwater Section and the
12
North Carolina Department of Human Resources, Solid Waste Management Section revealed
no underground storage tanks or hazardous waste sites in the project area.
Catawba County is a participant in the National Flood Insurance Regular Program. This site on
McLin Creek is included in a detailed F.E.M.A. study. Attached is a copy of the Flood Insurance
Rate Map, Figure 4, on which are shown the approximate limits of the 100-year flood plain in the
vicinity of the project.
On the basis of the above discussion, it is concluded that no significant adverse environmental
effects will result from implementation of the project.
The project is a Federal "Categorical Exclusion" due to its limited scope and lack of significant
environmental consequences.

Thank you for your letter of March 11, 1996, concerning the above project.
We have conducted a search of our maps and files and have located the following
structure of historical or architectural importance within the general area of this
project:
1930s concrete railroad bridge, adjacent to Bridge 94
We recommend that an architectural historian on your staff identify and evaluate
any structures over fifty years of age within the project area, and report the
findings to us.
There are no known archaeological sites within the proposed project area. Based
on our present knowledge of the area, it is unlikely that any archaeological
resources which may be eligible for inclusion in the National Register of Historic
Places will be affected by the project construction. We, therefore, recommend that
no archaeological investigation be conducted in connection with this project.
The above comments are made pursuant to Section 106 of the National Historic
Preservation Act and the Advisory Council on Historic Preservation's Regulations
for Compliance with Section 106 codified at 36 CFR Part 800.
Thank you for your cooperation and consideration. If you have questions

Dear Mr. Vick:
In reference to Bridges Nos. 82 and 94 on SR 1165 and 1722 for bus travel.
We have three buses crossing bridge no. 82 which will cause very little
mileage increase by detouring. Bridge no. 94 over Mclin Creek will cause
me an increase in mileage. The five buses will add 96 miles per day. The
large number of students at Catawba that we transport to Claremont is my
problem.
Sincerely,

SUBJECT: Comments on Group IX Bridge Replacements, Alleghany, Cleveland, McDowell,
Buncombe, and Catawba Counties.
This correspondence responds to a request by you for our review and comments regarding eleven
proposed bridge replacements in western North Carolina. Biological field staff of the North Carolina
Wildlife Resources Commission (WRC) have reviewed the information in your letter dated 11 March 1996
and have examined our records fish sampling data.
Our comments on these projects are listed below. All species and common names follow
"Common and Scientific Names of Fishes from the United States and Canada" by Robins et al. 1991
(American Fisheries Society Special Publication 20). Species listed in bold print are considered to be
intolerant to stream degradation under the North Carolina Index of Biotic Integrity used by the North
Carolina Division of Environmental Management to assess the biological integrity of streams.
B-2803 - Alleghany County, Bridge No. 52 over Little River, Bridge No. 56 over Pine Swamp Creek
Both the Little River and Pine Swamp Creek are designated Hatchery Supported Public Mountain
Trout Waters (PMTW) in the project area. We recently provided you with a memorandum dated
12 July 1995 with our scoping comments on this project (see attached).
B-2815 - Cleveland County, Bridge No. 35 on SR 1001 over Persimmon Creek
No fish data are available for Persimmon Creek, nor have we identified any special concerns
associated with this project.
B-2816 - Cleveland County, Bridge No. 230 on SR 1908 over Buffalo Creek
We have not identified any special concerns associated with this project. According to WRC
district files, the following fish species were collected in Buffalo Creek in 1980:

Group IX Page 5 April 10, 1996
Although we do not have any special concerns regarding several of these bridge
replacements, we recommend that the NCDOT incorporate the following measures into all bridge
replacement projects to minimize impacts to aquatic organisms:
1) Erosion controls should be installed where soil is disturbed and maintained until project
completion.
2) If concrete will be used, work must be accomplished so that wet concrete does not contact
stream water. This will lessen the chance of altering water chemistry and causing a fish
kill.
3) Heavy equipment should be operated from the bank rather than in stream channels in
order to minimize sedimentation and reduce the likelihood of introducing other pollutants
into streams.
4) Multi-celled reinforced concrete box culverts should be designed so that all water flows
through a single cell (or two if necessary) during low flow conditions. This could be
accomplished by constructing a low sill on the upstream end of the other cells that will
divert low flows to another cell. This will facilitate fish passage at low flows.
5) Temporary or permanent herbaceous vegetation should be planted on all bare soil within
15 days of ground disturbing activities to provide long-term erosion control.
'T'hank you for the opportunity to review and comment during the early stages of these projects. If
you have any questions regarding these comments, please contact me at 704/652-4257.

Subject: Proposed replacement of several bridges in Alleghany, Buncombe,
Catawba, Cleveland, and McDowell Counties, North Carolina
A copy of your letter of March 11. 1996, to the U.S. Fish and Wildlife
Service's (Service) Raleigh Field Office was forwarded to our office (we
received it on March 18. 1996). Our office handles project reviews and
requests of this nature for the western part of the state, including the
above-mentioned counties. The following comments are provided in
accordance with the provisions of the Fish and Wildlife Coordination Act,
as amended (16 U.S.C. 661-667e), and Section 7 of the Endangered Species
Act of 1973, as amended (16 U.S.C. 1531-1543) (Act).
According to the information provided in your letter, the following
bridges will be replaced: Bridge Numbers 52 and 56 on SR 1172 over the
Little River (Alleghany County): Bridge Number 512 on SR 2435 over the
Swannanoa River (Buncombe County): Bridge Number 82 on SR 1165 over Clark
Creek (Catawba County): Bridge Number 94 on SR 1722 over McLin Creek
(Catawba County): Bridge Number 35 on SR 1001 over Persimmon Creek
(Cleveland County): Bridge Number 230 on SR 1908 over Buffalo Creek
(Cleveland County): Bridge Number 13 on NC 198 over Buffalo Creek
(Cleveland County): Bridge Number 65 on SR 1760 over Muddy Creek
(McDowell County): Bridge Number 41 on SR 1147 over the Second Broad
River (McDowell County): Bridge Number 317 on SR 1267 over Cove Creek;
and Bridge Number 60 on SR 1764 over South Muddy Creek.
The Service is particularly concerned about: (1) the potential impacts
the proposed bridge replacement projects could have on federally listed
species and on Federal species of concern and (2) the potential impacts
to stream and wetland ecosystems within the project areas.
We have reviewed our files and believe the environmental document should
evaluate possible impacts to the following federally listed species
and/or Federal species of concern (these include aquatic animal species
2
known from a particular stream system for one of the proposed bridge
projects and plant species that may occur along the banks of
streams/rivers):
Alleghanv County
Hellbender (Crvptobranchus alleQaniensis) - Federal species of concern.
This species generally is found beneath large flat stones or logs in
shallow clear-running streams and rivers. It is presently known
from at least one location in the Little River, 7 miles east of
Sparta.
Kanawha minnow (Phenocobius teretulus) - Federal species of concern.
This species is endemic to large clear streams within the New River
drainage of North Carolina, Virginia, and West Virginia. It is
presently known from at least one location in the Little River,
0.5 mile downstream of the NC 18 bridge.
Buncombe County
Hellbender (Crvptobranchus alleQaniensis) - Federal species of concern.
There is a record of this species in the Swannanoa River near Black
Mountain. ,
Spotfin chub (Hvbopsis monacha) - Federally threatened. A species
endemic to the Tennessee River drainage. The Little Tennessee River
presently supports the only extant population in North Carolina:
however, there is a historical record from the Swannanoa River in
Asheville.
Appalachian elktoe (Alasmidonta raveneliana) - Federally endangered.
This species is endemic to the upper Tennessee River. It generally
occurs in the riffle areas of large rivers that have cobble and
gravel substrates. There are only a few extant populations left in
the Little Tennessee River. Toe River, Cane River, and Nolichucky
River systems. There is a historical record from the Swannanoa
River.
French Broad crayfish (Cambarus reburrus) - Federal species of concern.
This species is endemic to North Carolina and is known from the
headwater portions of the French Broad River and one stream in the
Savannah River drainage. It was once found in the Swannanoa River
near Black Mountain.
French Broad heartleaf (Hexastvlis rhombiformis) - Federal species of
concern. This species is generally found in association with other
acidophiles, such as ericaceacous shrubs, hemlock, rhododendron, and
mountain Laurel.

3
Butternut (Ju lans cinerea) - Federal species of concern. This species
is generally found in cove forests and rich woods, including
floodplain forests.
Sweet pinesap (Monotropsis odorata) - Federal species of concern. This
species is generally found in dry forests and on river bluffs.
Virginia spiraea (Sipiraea virginiana) - Federally threatened. This
species occurs within the scour zone on the banks of high-gradient
streams or on braided features such as point bars, natural levees,
or meander scrolls of the lower reaches.of streams. It may occur
within the floodplain, but it is most often found at the water's
edge. There is a historical record of this species along Hominy
Creek near Asheville.
Catawba County
Dwarf-flowered heartleaf (Hexastvlis naniflora) - Federally threatened.
This species has been found along several creeks in the county,
including Brushy Creek. Sandy Run, and Poundingmill Creek.
Cleveland County
Dwarf-flowered heartleaf (Hexastvlis naniflora) - Federally threatened.
This species has been found along several tributaries to the Henry

Bennett's Mill Cave water slater (Caecidotea carolinensis) - Federal
species of concern. This species is presently known from one
locality in North Carolina at a cave located on the banks of Muddy
Creek east of Marion.
Butternut (Juglans cinerea) - Federal species of concern. This species
is generally found in cove forests and rich woods, including
floodplain forests.
Sweet pinesap (Monotroosis odorata) - Federal species of concern. This
species is generally found in dry forests and on river bluffs.
There is one known population located along the banks of South Muddy
Creek in the headwaters area.
Northern oconee-bells (Shortia galacifolia var. brevistvla) - Federal
species of concern. This species grows in various habitats, from
rocks near water falls, in sand at the edge of running water, in
shady deep moist loam soils, and on dry hillsides. It favors cool,
damp, shady stream banks with fertile, moderately acid, soils.

The presence or absence of the above-mentioned species in the project
impact areas should be addressed in any environmental document prepared
for these projects. Please note that the legal responsibilities of a
Federal agency or their designated non-Federal representative with regard
to federally listed endangered and threatened species under Section 7 of
the Act are on file with the Federal Highway Administration. Also,
please note that Federal species of concern are not legally protected
under the Act and are not subject to any of its provisions, including
Section 7, unless they are formally proposed or listed as endangered or
threatened. We are including these species in our response in order to
give you advance notification and to request your assistance in
protecting them.
Additionally, the Service believes the environmental document(s) for the
proposed projects should address the following issues: (1) an evaluation
of the various bridge replacement alternatives and structures (e.g.,
replacement at the existing location versus upstream or downstream of the
existing structure), (2) any special measures proposed to minimize
sedimentation during construction; and (3) any measures that will be
implemented to minimize impacts to fish and wildlife habitat (e.g..
protecting riparian vegetation whenever possible).
We appreciate the opportunity to provide these scoping comments and
request that you keep us informed of the progress of these projects. In
any future correspondence concerning this project, please reference our
Log Number 4-2-96-057.

MEMORANDUM
To: Jim Buck
From: Eric Galamb4
Subject: Water Quality Checklist for Group IX Bridge Replacement Projects
The Water Quality Section of the Division of Environmental Management requests that
DOT consider the following generic environmental commitments for bridge
replacements:
A. DEM requests that DOT strictly adhere to North Carolina regulations entitled,
"Design Standards in Sensitive Watersheds" (15A NCAC 04B .0024) throughout
design and construction for this project in the area that drains to streams having
WS (water supply), ORW (outstanding resource water), HQW (high quality
water), B (body contact), SA (shellfish water) or Tr (trout water) classifications
to protect existing uses.
B. DEM requests that bridges be replaced in existing location with road closure. If
an on-site detour or road realignment is necessary, the approach fills should be
removed to pre-construction contour and revegetated with native tree species at
320 stems per acre.
C. DEM requests that weep holes not be installed in the replacement bridges in
order to prevent sediment and other pollutants from entering the body of water.
If this is not completely possible, weep holes should not be installed directly
over water.
D. Wetland impacts should be avoided (including sediment and erosion control
structures/measures). If this is not possible, alternatives that minimize wetland
impacts should be chosen. Mitigation for unavoidable impacts may be required.
E. Borrow/waste areas should avoid wetlands. It is likely that compensatory
mitigation will be required if wetlands are impacted by waste or borrow.
Please be aware that 401 Certification may be denied if wetland or water impacts
have not been avoided and minimized to the maximum extent practicable.

1. FLOOD PLAINS: POC - Bobby L. Willis, Special Studies and Flood Plain
Services Section, at [phone]
All of the bridges, except for Alleghany and Buncombe Counties, are within the
planning jurisdiction of the U.S. Army Corps of Engineers (USAGE), Wilmington
District. With the exception of Alleghany and Cleveland Counties, these bridges are
located within counties which participate in the National Flood Insurance Program
(NFIP). Alleghany County has flood hazard areas identified on Flood Hazard Boundary
Maps, but has not had detailed mapping done and does not participate in the program.
Cleveland County has mapping done on Flood Insurance Rate Maps (FIRMs) in
anticipation of future participation in the NFIP, but does not currently participate in the
program. From the various FIRMs, it appears that both approximate study and detail
study streams are involved. (Detail study streams are those with 100-year flood
elevations determined and a floodway defined.) A summary of flood plain information
pertaining to these bridges is contained in the following table. The FIRMs are from the
county flood insurance study unless otherwise noted.

1. FLOOD PLAINS: (Continued)
Enclosed, for your information on the detail study streams, is a copy of the Federal
Emergency Management Agency's "Procedures for 'No Rise' Certification for Proposed
Developments in Regulatory Floodways°. In addition, we suggest coordination with the
respective counties or communities for compliance with their flood plain ordinances and
any changes, if required, to their flood insurance maps and reports.
Buncombe County is within the planning jurisdiction of the USACE, Nashville
District, and the Tennessee Valley Authority (TVA) with respect to any construction or
development involving the flood plains. The Nashville District does not currently have
projects that would be affected by this proposed project. Mr. Jamie James may be
contacted at [phone] for further information and comments from the Nashville
District. Flood plain concerns are normally addressed within the TVA Section 26a
permitting process. A 26a permit is required for all construction or development
involving streams or flood plains in the Tennessee River drainage basin. Mr. Roger
Milstead at [phone] should be contacted for information on the TVA 26a
permitting process. The project should be designed to meet the requirements of the
National Flood Insurance Program (NFIP), administered by the Federal Emergency
Management Agency (FEMA), and be in compliance with all local ordinances. The
engineering point of contact for the NFIP in this FEMA region is Ms. Bel Marquez, who
may be reached at [phone]. Specific questions pertaining to community flood
plain regulations or developments should be referred to the local building official.
Alleghany County is within the planning jurisdiction of the USACE,
Huntington District. The Huntington District does not currently have projects that would
be affected by the proposed project. Mr. Larry Workman may be contacted at
[phone] for further information and comments from the Huntington District.
2. WATERS AND WETLANDS: POC - Raleigh and Asheville Field Offices,
Regulatory Branch (Individual POC's are listed following the comments.)
All work restricted to existing high ground will not require prior Federal permit
authorization. However, Department of the Army permit authorization pursuant to
Section 404 of the Clean Water Act of 1977, as amended, will be required for the
discharge of excavated or fill material in waters of the United States or any adjacent
and/or isolated wetlands in conjunction with your proposed bridge replacements,
including disposal of construction debris.

2. WATERS AND WETLANDS: (Continued)
The replacement of these bridges may be eligible for nationwide permit
authorization [33 CFR 330.5(a)(23)J as a Categorical Exclusion, depending upon the
amount of jurisdictional wetlands to be impacted by a project and the construction
techniques utilized. Please be reminded that prior to utilization of nationwide permits
within any of the 25 designated mountain trout counties, you must obtain a letter with
recommendation(s) from the North Carolina Wildlife Resources Commission and a
letter of concurrence from the U.S. Army Corps of Engineers, Wilmington District
Engineer. The mountain trout designation carries discretionary authority for the
utilization of nationwide permits. In addition, any jurisdictional impacts associated with
temporary access roads or detours, cofferdams, or other dewatering structures should
be addressed in the Categorical Exclusion documentation in order to be authorized by
Nationwide Permit No. 23 (NWP 23). If such information is not contained within the
Categorical Exclusion documentation, then other DA permits may be required prior to
construction activities.
Although these projects may qualify for NWP 23 as a categorical exclusion, the
project planning report should contain sufficient information to document that the
proposed activity does not have more than a minimal individual or cumulative impact on
the aquatic environment. Accordingly, we offer the following comments and
recommendations to be addressed in the planning report:
a. The report should contain the amount of permanent and temporary impacts to
waters and wetlands as well as a description of the type of habitat that will be affected.
b. Off-site detours are always preferable to on-site (temporary) detours in
wetlands. If an on-site detour is the recommended action, justification should be
provided.
c. Project commitments should include the removal of all temporary fills from
waters and wetlands. In addition, if undercutting is necessary for temporary detours,
the undercut material should be stockpiled to be used to restore the site.
d. The report should address impacts to recreational navigation (if any) if a bridge
span will be replaced with a box culvert.
e. The report should address potential impacts to anadromous fish passage if a
bridge span will be replaced with culverts.

PROCEDURES FOR "NO-RISE" CERTIFICATION
PROPOSED DEVELOPMENTS IN REGULATORY FLOC
Section 60.3 (d) (3) of the National Flood Insurance Program (NFIP)
regulations states that a community shall "prohibit encroachments,
including fill, new construction, substantial improvements, and
other development within the adopted regulatory floodway unless it
has been demonstrated through hydrologic and hydraulic analyses
performed in accordance with standard engineering practice that the
proposed encroachment would not result in any increase in flood
levels within the community during the occurrence of the base (100-
year) flood discharge."
Prior to issuing any building grading or development permits
involving activities in a regulatory floodway, the community must
obtain a certification stating the proposed development will not
impact the pre-project base flood elevations, floodway elevations,
or floodway data widths. The certification should be obtained from
the permittee and be signed and sealed by a professional engineer.
The engineering or "no-rise" certification must be supported by
technical data. The supporting technical data should be based upon
the standard step-backwater computer model utilized to develop the
100-year floodway shown on. the community's effective Flood
Insurance Rate Map or Flood Boundary and Floodway Map (FBFM) and
the results tabulated in the community's Flood Insurance Study
(FIS).
Although communities are required to review and approve the "no-
rise" submittals, they may request technical assistance and review
from the FEMA regional office. However, if this alternative is
chosen, the community must review the technical submittal package
and verify that all supporting data, listed in the following
paragraphs, are included in the package before forwarding to FEMA.
-2-
To support a "no-rise" certification for proposed developments
encroaching into the regulatory floodway, a community will require
that the following procedures be followed:
Currently Effective Model
1. Furnish a written request for the step-
backwater computer model for the specified
stream and community, identifying the limits
of the requested data. A fee will be assessed
for providing the data. Send data requests
to:
Federal Emergency Management Agency
1371 Peachtree Street N.E., Suite 735
Atlanta, Georgia 30309
or to:
FIS Information Specialist
Dewberry & Davis
8401 Arlington Boulevard
Fairfax, Virginia 22031-4666
Duplicate Effective Model
2. Upon receipt of the.step-backwater computer
model, the engineer should run the original
step-backwater model-to duplicate the data in
the effective FIS.
Existing Conditions Model
3. Revise the original step-backwater model to
reflect site specific existing conditions by
adding new cross-sections (two or more), in the
vicinity of the proposed development, without
the proposed development in place. Floodway
limits should be manually. set at the new
cross-section locations by measuring from the
effective FIRM or FBFM. The cumulative reach
lengths of the stream should also .remain
unchanged. The results of these analyses will
indicate the 100-year floodway elevations for
revised existing conditions at the proposed
project site.

-3-
Proposed Conditions Model
4. Modify the revised existing conditions model
to reflect the proposed development at the new
cross-sections, while retaining the currently
adopted floodway widths. The overbank
roughness coefficients should remain the same
unless a reasonable explanation of how the
proposed development will impact Manning's "n"
values should be included with the supporting
data. The results of this floodway run will
indicate the 100-year floodway elevations for
proposed conditions at the project site.
These results must indicate NO impact on the
100-year flood elevations, floodway
elevations, or floodway widths shown in the
Duplicate `Effective Model or in the Existing
Conditions Model.
The original FIS model, the duplicate effective FIS model, the
revised existing conditions model, and the proposed conditions
model should all produce the same exact results.
The "no-rise" supporting data and -a copy of the engineering
certification must be submitted to and reviewed by the appropriate
community official prior to issuing a permit:
The "no-rise" supporting data should include, but may not be
limited to:
a. Duplicate of the original FIS step-backwater model
printout or floppy disk.
b. -Revised existing conditions.step-backwater model.
C. Proposed conditions step-backwater model.
d. FIRM and topographic map, showing floodplain and
floodway, the additional cross-sections, the
site location with the proposed topographic
modification superimposed onto the maps, and a
photocopy of the effective FIRM or FBFM showing the
current regulatory floodway.
e. Documentation clearly stating analysis procedures.
All modifications made to the original FIS model to
represent revised existing conditions, as well as
