Dear Sir:
Subject: Davidson County, Replacement of Bridge No. 6 over Dyker's Creek on
SR 1186, Federal Aid Project BRZ-1186(1), State Project No. 8.260220 1,
TIP No. B-2538.
. Please find enclosed three copies of the project planning report for the above
referenced project. The project involves the replacement of bridge number 6 along existing
alignment of SR 1186. Traffic will be detoured along existing secondary roads during the
6 month construction period. The project will not result in any wetland impacts but will
require minor fill in surface waters.
The project is being processed by the Federal Highway Administration as a
"Categorical Exclusion" 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 in accordance with 33 CFR 330 Appendix A (B-23). The provisions of Section
330.4 and Appendix A (C) of these regulations will be followed in the construction of the
project.
We anticipate that 401 General Certification No. 2745 (Categorical Exclusion) will
apply to this project, and are providing one copy of the CE document to the North
Carolina Department of Environment, Health and Natural Resources, Division of
Environmental Management, for their review.

Over Dyker's Creek
Federal Aid Project BRZ-1186(1)
State Project 8.2602201
T.I.P. I.D. No. B-2538
Bridge No. 6 is included in the current Transportation Improvement
Program. The location is shown in Figure 1. No substantial environmental
impacts are anticipated. The project has been classified as a
"categorical exclusion".
I. SUMMARY OF RECOMMENDATIONS
Bridge No. 6 should be replaced at its existing location as shown by
Recommended Alternate 1 in Figure 2. The recommended structure is a
triple 10 ft. by 10 ft. reinforced concrete box culvert. The length of
the culvert should be adequate to accommodate a 22-foot pavement with
6-foot graded shoulders. Approaches should be a 22-foot pavement with
6-foot graded shoulders.
The roadway grade at this crossing should be raised approximately
three feet to improve the vertical alignment. The horizontal alignment
will remain approximately the same as the existing alignment.
Traffic will be detoured along existing secondary roads during the
6-month construction period, as shown in Figure 1.
Estimated cost, based on current prices, is $ 249,000. The estimated
cost of the project, as shown in the 1995-2001 Transportation Improvement
Program, is $ 425,000.
II. SUMMARY OF ENVIRONMENTAL COMMITMENTS
All standard procedures and measures will be implemented to avoid and
minimize environmental impacts.
No jurisdictional wetlands will be impacted as a result of project
construction.
A Nationwide Section 404 permit and (DEM) Section 401 Water Quality
Certification will be required prior to project construction.
Construction is scheduled to begin during the summer months when
school is not in session to minimize inconvenience to school buses.
III. ANTICIPATED DESIGN EXCEPTIONS
A design exception is anticipated for the 30 MPH design speed of the
recommended alternate.
2
IV. EXISTING CONDITIONS
SR 1186 is classified as a minor collector in the Statewide
Functional Classification System and is not a Federal Aid road.
In the vicinity of the bridge, SR 1186 has an 18-foot pavement with
4-foot to 5-foot shoulders (see Figure 3). The one-lane structure is
situated 14 feet above the creek bed. The approaches are on embankments
6-8 feet above natural ground. Development in the surrounding area is
rural residential.
There is an eight inch water line on the west side of the existing
structure and a twenty-four inch water line on the east side of the
existing structure.
The current traffic volume of 1100 VPD is expected to increase to
1800 VPD by the year 2017. The projected volume includes 1% truck-tractor
semi-trailer (TTST) and 2% dual-tired vehicles (DT).
The existing bridge (see Figure 3) was constructed in 1956. The
superstructure consists of a timber deck with I-beams. The substructure
consists of timber caps and piles.
The overall length of this bridge is 81 feet and the clear roadway
width is 15.9 feet. The posted weight limit is 10 tons for single
vehicles and 13 tons for trucks with trailers.
Bridge No. 6 .has a sufficiency rating of 16.0 compared to a rating of
100 for a new structure. The estimated remaining life of the existing
bridge is 2 years.
The speed limit is not posted.
Two accidents were reported in the vicinity of Bridge No. 6 during
the period from January, 1990 to January, 1992.
Three school buses travel across the studied bridge twice daily.
V. ALTERNATIVES
Four methods of replacing Bridge No. 6 were studied.
The alternates studied, shown in Figure 2, are as follows:
Alternate 1 (Recommended) - will replace the bridge at its present
location with a triple 10 ft. by 10 ft. reinforced concrete box
culvert. The grade for this alternate will be raised approximately
3 feet. This alignment will provide a design speed of approximately
30 MPH. Traffic is to be detoured along existing roads, as shown in
Figure 1.
Alternate 1A - is identical to Alternate 1 except that during
construction, traffic would be maintained on-site with a temporary
detour on the west side of the existing structure.
3
Alternate 2 - would replace Bridge No. 6 approximately 20 feet east of
the existing roadway. This alternate would also consist of a triple
10 ft. by 10 ft. reinforced concrete box culvert. Traffic would be
maintained on the existing structure during the construction period.
The design speed would be about 60 MPH. Also, this alternate
requires the relocation of two families.
Alternate 3 - would replace the bridge in its existing location. This
alternate would require significant modification of the south
approach.
The "do-nothing" alternative would eventually necessitate closure of
the bridge. This is not prudent due to the traffic service provided by
SR 1186.
Investigation of the existing structure by the Bridge Maintenance
Unit indicates that rehabilitation of the old bridge is not feasible due
to its age and deteriorated condition.
VI. ESTIMATED COST
Alternate 3 (see Figure 2) was studied to determine if a higher
design speed could be provided without relocating residents. This
alternate would require significant relocation of the south approach. The
alternate was considered but rejected due to excessive costs ($792,000).
Estimated costs of the competitive alternatives studied are as
follows:
Recommended
Alternate 1 Alternate 1A Alternate 2 Alternate 3
Structure $ 88,000 $ 88,000 $ 88,000 $ 88,000

VII. TRAFFIC DETOUR
The Division Engineer concurs that traffic can be detoured on
existing roads during the construction period, as shown in Figure 1. The
average vehicle will be required to travel an additional 1.6 miles. A
6-month road closure period is anticipated.
Maintaining traffic on-site is estimated to cost an additional
$111,000 and is not justifiable due to the excessive cost of the on-site
detour and the availability of a suitable detour route. The detour
roadway and bridges are adequate to accommodate affected traffic during
the construction period.
The Davidson County School Bus Supervisor indicates road closure of
SR 1186 is tolerable but prefers road closure during the summer months.
Construction is scheduled to begin during the summer months when school is
not in session to minimize inconvenience to school buses.
VIII. RECOMMENDED IMPROVEMENTS
Alternate 1 was selected due to its lower cost and minimum property
impact. An alignment improvement (Alternate 2) would require the
acquisition of two residences and is not justifiable due to the additional
cost of $ 245,000.
Bridge No. 6 should be replaced at its existing location with a
triple barrel 10 ft. by 10 ft. reinforced concrete box culvert, as shown
by Recommended Alternate 1 in Figure 2.
The roadway grade should be raised approximately three feet to
improve the vertical alignment. A 22-foot travelway with 6-foot grassed
shoulders will be provided on the approaches.
Based on preliminary studies, the Hydraulics Unit recommends the new
grade should be raised approximately three feet to improve the vertical
alignment.
The length and height may be increased or decreased as necessary to
accommodate peak flows as determined by further hydrological analysis and
hydraulic design.
Traffic will be detoured on existing roads during the six month
construction period, as shown in Figure 1.
The Division Engineer concurs with the recommendation of Alternate 1.
IX. ENVIRONMENTAL EFFECTS
The project is expected to have an overall positive impact.
Replacement of an inadequate bridge will result in safer traffic
operations.
5
The project is considered to be a "categorical exclusion" due to its
limited scope and insignificant environmental consequences.
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 change in land use is expected to result from
construction of the project.
No adverse effect on families or communities is anticipated.
Right-of-way acquisition will be limited.
No adverse effect on public facilities or services is expected. 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.
The project is subject to compliance with Section 106 of the National
Historic Preservation Act of 1966, as amended, implemented by the Advisory
Council on Historic Preservation's Regulations for Compliance with Section
106, codified at 36 CFR Part 800. Section 106 requires that if a
federally-funded, licensed, or permitted project has an effect on a
property listed on or eligible for inclusion in the National Register of
Historic Places, the Advisory Council on Historic Preservation be given
the opportunity to comment.
Photographs, maps, and information about the area of potential effect
were provided by the North Carolina Department of Transportation and
reviewed with the State Historic Preservation Office (SHPO). There are no
historic structures within the area of potential effect, and the SHPO
recommended that no historic architectural survey be conducted for this
project. A June 16, 1992 letter of concurrence from the SHPO is included
in the Appendix.
Since there are no properties either listed in or eligible for the
National Resister in the APE, no further compliance with Section 106 is
required.
An archaeological survey was conducted for this bridge replacement
project to locate and assess any significant archaeological remains that
could be damaged or destroyed. A single prehistoric site, evidenced by
three rhyolite flakes was recorded in a cornfield on the west side of
Dyker's Creek. The results of the archaeological study indicate that the
site lacks integrity and is not significant. Therefore, no further work
is recommended. Correspondence from the SHPO regarding the archaeological
aspects of the project is included in the Appendix.
6
The structure is to be replaced at the existing location. Therefore,
the project is exempt from the Farmland Protection Policy Act.
The proposed project occurs in the western part of Davidson County,
approximately 10 miles west of Lexington.
Davidson County is in the central portion of the Piedmont
Physiographic Province. The topography of the area is characterized as
rolling hills and broad river floodplains. The soils of this region
consist of Chewacla and Pacolet soils. Chewacla soils consist of very
deep, somewhat poorly drained soils on nearly level flood plains. Pacolet
soils consist of well drained, moderately permeable, soils of the piedmont
uplands.
Dyker's Creek is part of the Yadkin-Peedee River Basin. Dyker's Creek
flow from east to west and empties into the Yadkin River approximately 0.5
miles southwest of the project location.
Stream width is approximately 12 feet at the project crossing. Depth
varies from 0.5 feet to 1.0 feet. The substrate is composed of gravel,
sand, and silt.
The waters of the Dyker's Creek carry the Best Usage Classification
of C as assigned by the North Carolina Department of Environment, Health
and Natural Resources (DEHNR), 1993. Class C designates waters suitable
for aquatic life propagation and survival, fishing, wildlife, secondary
recreation and agriculture. A segment of Dyker's Creek from a point 0.3
mi upstream of the mouth to Yadkin River is classified as (WS-IV) Critical
Area (CA). This CA occurs within 0.5 mi downstream of the project study
site in the Yadkin River. CA means the area adjacent to a water supply
intake or reservoir where risk associated with pollution is greater than
from the remaining portions of the watershed.
The Benthic Macroinvertebrate Ambient Network (BMAN), assesses water
quality by sampling for selected benthic Macroinvertebrate organisms. The
species richness and overall biomass are reflections of water quality. No
BMAN information exists for the project study area.
The DEM National Pollutant Discharge Elimination System (NPDES)
report does not lists any permitted discharge sources for the project
site.
Potential impacts to water resources include decreases of dissolved
oxygen and changes in temperature. These impacts are frequently due to
removal of the streamside canopy and removal/burial of aquatic vegetation.
Sedimentation and substrate disturbance occurring during construction can
significantly reduce water clarity.
Sedimentation and erosion control measures (Best Management Practices
and Sediment control guidelines) are required by DEHNR during the
construction stage of the projects impacting CA's. Grass berms along
construction areas help decrease erosion and allow toxic substances to be
absorbed into soil before these substances reach waterways. Poorly managed
application of sedimentation control policies will result in serious
damage to the aquatic environment.
7
If stream channel relocation is required and if the stream relocation
is greater than 100 feet in length or greater than 50 feet to one side,
consultation with the U. S. Fish and Wildlife Service and the North
Carolina Wildlife Resources Commission will be required, per the Fish and
Wildlife Coordination Act, as amended (16 USC 661-667d). Relocated streams
will be designed to have similar characteristics (depth, width, and
substrate) as the original stream. This also includes re-establishment of
streamside vegetation.
Three distinct biotic community types were identified in the project
impact zone: Man-dominated, Alluvial Forest, and Mixed Hardwood Forest
communities. However, some degree of overlap exists between communities,
particularly with the faunal components. Numerous terrestrial animals are
highly adaptive and populate a variety of habitats; therefore, many of the
species discussed below may occur in all of the community types described.
The Man-dominated community is a highly disturbed community that
includes roadside, lawn, and agricultural habitats. Many plant species,
characteristic of the mowed roadsides are adapted to disturbed and
maintained habitats. The intensely maintained areas are dominated by
fescue, clover, plantain, and Bermuda grass as well as a variety of
landscape ornamentals. Less maintained areas exhibit encroachment by
kudzu and multiflora rose.
Many animals present in these disturbed habitats are opportunistic
and capable of surviving on a variety of forage resources, ranging from
vegetation (flowers, leaves, seeds, and fruits) to animal matter (living
and dead). Virginia opossum, American crow, and mourning dove are
examples of species attracted to lawns and roadside habitats. Also,
several species of mice inhabit the less maintained margins or ecotones of
road shoulders. Mortality among animals which migrate across roadways
provides forage for opportunistic species such as turkey vulture and
Virginia opossum which may in turn become fatalities and subsequently
foraged items themselves.
The Alluvial Forest community is a narrow buffer along the floodplain
and banks of Dyker's Creek. Canopy species include river birch, box
elder, and sycamore. Undergrowth is dense and includes saplings of the
previously mentioned tree species as well as violet, touch-me-not,
Joe-pye-weed, and poison ivy. Sections to the west of the existing bridge
are being over run by multiflora rose and kudzu.
Animals found in this forested habitat include southern leopard frog,
tufted titmouse, and raccoon. These alluvial forests function as
corridors for animals moving to and from foraging and bedding/nesting
areas.
The Mixed Hardwood Forest community is located east of SR 1186 and
upslope of the alluvial forest community south of Dyker's Creek. White
oak, sycamore, and sweet gum are the dominant trees of this forest. A
scattered understory is composed of mulberry, ironwood, and hackberry
8
along with a tangled ground cover of primarily Japanese honeysuckle and
poison ivy. Both the mixed hardwood forest and the alluvial forest
communities are likely remnants of more extensive forested stands present
in the project area prior to impacts resulting from logging and
agricultural practices.
White tailed deer browse here on low growing vegetation in the spring
and summer and forage on mast as fruits mature into the fall and winter.
Other creatures which frequent the vegetative layers of the mixed hardwood
forest include gray squirrel, red-bellied woodpecker, and red-eyed vireo.
Marbled salamander and slimy salamander may be found beneath leaf litter,
rocks and/or fallen logs.
One aquatic community, Dyker's Creek, will be impacted by the
proposed project. Physical characteristics of- the water body and
condition of the water resource reflect faunal composition of the aquatic
communities. Terrestrial communities adjacent to a water resource also
greatly influence aquatic communities.
Dyker's Creek flows east to west through the project study site and
at the time of the site visit contained stained, moderate flow. Scoured
stream banks, heavy siltation and clogging are evidence of erodible
landscape in the project study area. Deforestation and agriculture in the
terrain surrounding Dyker's Creek are likely contributors to the
sedimentation evident at the project site.
Little evidence of animal life was observed at the project site.
Mosquito fish, darters, snails, and other assorted invertebrates were
found scattered in Dyker's Creek.
Project construction will result in clearing and degradation of
portions of the three terrestrial community types described. The
estimated loss to these communities by construction of the alternates is
listed in the table below. It should be noted that estimated impacts were
derived using the entire proposed right of way (80-foot impact width).
Project construction often does not require the entire right of way and,
therefore, actual impacts may be considerably less.

Wetlands and surface waters fall under the broad category of "Waters
of the United States" as defined in 33 CFR 328.3, in accordance with
provisions of Section 404 of the Clean Water Act (33 U.S. C. 1344).
Wetlands are those areas that are inundated or saturated by surface or
ground water at the frequency and duration sufficient to support, and
under normal circumstances do support, a prevalence of vegetation
typically adapted to life in saturated conditions. No jurisdictional
wetlands will be impacted as a result of project construction.
Impacts to Waters of the United States fall under the jurisdiction of
the U.S. Army Corps of Engineers (COE). A Nationwide permit 33 CFR 330.5
(A)23, for impacts to surface waters of Dyker's Creek, is likely to be
applicable. This permit authorizes activities undertaken, assisted,
authorized, regulated, funded or financed in whole, or in part, by another
Federal agency or department. That agency or department has determined
that the activity is categorically excluded from environmental
documentation, because it will neither individually or cumulatively have a
significant environmental effect.
A North Carolina Division of Environmental Management (DEM) Section
401 (1665) Water Quality General Certification is also required, prior to
issuance of the Nationwide permit.
Projects authorized under Nationwide Permits usually do not require
compensatory mitigation according to the 1989 Memorandum of Agreement
between the Environmental Protection Agency and the Department of the
Army.
Federal law requires that any action, which has the potential to
jeopardize the continued existence of any species classified as federally
protected, is subject to review by the U. S. Fish and Wildlife Service
and/or the National Marine Fisheries Service under the provisions of the
Endangered Species Act (ESA) of 1973, as amended. Rare species receive
additional protection under separate state statutes. In North Carolina
protection of plant species falls under N.C. General statutes (G.S.)
106-202.12 to 106-202.19 of 1979. Wildlife protection falls under G.S.
113-331 to 113-337 of 1987.
Plants and Animals with federal classifications 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. As of July 8, 1994 the U. S. Fish and
Wildlife Service lists the federally-endangered Schweinitz's sunflower
(Helianthus schweinitzii) for Davidson County.
A plant-by-plant survey was conducted by an NCDOT biologist on
June 6, 1994, to determine if any Helianthus species were present in
suitable habitat associated with the project Right-of-Way. No sunflower
species were found along the project Right-of-Way, therefore it can be
concluded that the subject project will not impact Schweinitz's sunflower.
10
This project is located in the Northern Piedmont Air Quality Region.
The ambient air quality for Davidson County has been determined to be in
compliance with the National Ambient Air Quality Standards. This project
is not anticipated to create any adverse effect on air quality of this
attainment area.
This project will not substantially increase traffic volumes.
Therefore, its impact on noise levels and air quality will be
insignificant. 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 and laws and regulations of
the North Carolina State Implementation Plans for air quality in
compliance with 15 NCAC 2D.0520.
Davidson County is a participant in the National Flood Insurance
Regular Program; however, both the Dyker's Creek and the Yadkin River
Floodplains are beyond the limit of the detailed flood study and hence
have no established floodway. Therefore, roadway fill associated with the
recommended replacement alternative will not warrant a floodway
modification. The approximate 100-year floodplain in the project area is
shown in Figure 4. This location is beyond the limit of the detailed
flood study; therefore, no regulatory floodway has been established in
this area. The floodplain is rural and wooded interspersed with
cultivated fields in the vicinity of the project, and the proposed bridge
replacement will not have a detrimental effect on the existing floodplain.
Existing drainage patterns and groundwater will not be affected by
the proposed bridge replacement. Although there does not appear to be
evidence of significant scour potential with the sharp curve in the river
at this crossing warrants that careful design consideration be given to
protecting the banks from erosion scour. Aside from that, standard
erosion and sedimentation control devices and measures should be adequate,
provided they are properly installed and maintained.
On the basis of the above discussion, it is concluded that no adverse
environmental effects will result from implementation of the project.

Dear Mr. Graf:
Division of Archives and History
William S. Price, Jr., Director
On May 28, 1992, Robin Stancil of our staff met with North Carolina
Department of Transportation (NCDOT) staff for a meeting of the minds
concerning the above project. We reported our available information on
historic architectural and archaeological surveys and resources along with
our recommendations. NCDOT provided project area photographs and aerial
photographs at the meeting and for our use afterwards.
Based upon our review of the photographs and the information discussed at
the meeting, we offer our preliminary comments regarding this project.
In terms of historic architectural resources, we are aware of no historic
structures located within the area of potential effect. We recommend that
no historic architectural survey be conducted for this project.
Two recorded archaeological sites are in the project vicinity, but are not
likely to be affected by the bridge replacement. If borrow pits are planned
for the area or if the road south of Dyker's Creek is to be realigned, then the
two sites should be investigated.
Having provided this information, we look forward to receipt of either a
Categorical Exclusion or Environmental Assessment which indicates how
NCDOT addressed our concerns.
The above comments are made pursuant to Section 106 of the National
Historic Preservation Act of 1966 and the Advisory Council on Historic
Preservation's Regulations for Compliance with Section 106, codified at 36
CFR Part 800.
