3. Actions Required By Other Agencies
A Section 401 Water Quality Certification will be required from the North Carolina
Department of Environment and Natural Resources (NCDENR), Division of Water Quality
(DWQ). A Section 404 Permit will be required from the U.S. Army Corps of Engineers for
the discharge of dredged or fill materials into waters of the United States.
4. Proposed Project
McLean Drive Extension is a proposed minor thoroughfare extension from the current
intersection of US 321 and McLean Drive (SR 1180) to the intersection of Hibriten Drive

(SR 1178) and Haigler Road (SR 1711), see Figure 1-1.
The proposed project will serve local traffic and provide access for future development. The
Extension will begin as a divided four-lane roadway with curbs-and-gutters at US 321 and
continue for approximately 1500 feet before tapering to a two-lane roadway with grass
shoulders. The project is approximately 0.98 miles in length. The project is included in the
2000-2006 NCDOT Transportation Improvement Program (TIP) as TIP Project No. U-3813.
i
Construction is scheduled to begin in Fiscal Year 2000. The estimated TIP construction cost
of the project is $1.60 million.
5. Description of the Project Area
The project area is located in the City of Lenoir in Caldwell County. The southern terminus
is US 321 and the northern terminus is SR 1178, Hibriten Drive. Zoned primarily for
residential uses with commercial use at the proposed intersection of US 321 and McLean
Drive Extension, the project area is currently heavily wooded, vacant land. The topography
of the area varies from rolling hills to hilly with cross slopes typically ranging from 10
percent to 25 percent. Valleys containing stream channels periodically split the landscape.
A commercial development is currently under construction at the intersection of US 321 and
the proposed McLean Drive Extension.
6. Alternatives Considered
The proposed project is anticipated to help reduce future traffic congestion along US 321 and
at the intersection of US 321 and NC 18 due to increased commercial development, and to
provide access for the projected residential development in the area. Two alternatives were
considered: the Build Alternative and the No-Build Alternative. .
Build alternative alignments were considered which would minimize impacts on the
environment and would provide the needed traffic service. The No-Build Alternative would
avoid negative impacts associated with construction. However, traffic congestion on US 321
in the No-Build Alternative would increase at the US 321 /McLean Drive (SR 1180)
intersection due to increasing commercial development. With the No-Build Alternative,
proposed residential and commercial development in the project area would be hindered.

7. Environmental Impacts
• Acquisition of 4.29 acres of land for right-of-way and 3.4 acres of land for construction
easements.
• Increase in noise levels that will approach the FHWA noise abatement criteria (66 dBA
for land located along the existing roadway for a distance of approximately 12 feet
outside the right-of-way).
• Clearing and grading of approximately 12 acres of mixed hardwood forest.
• Culverting of approximately 1788 linear feet of unnamed low flow tributaries to Lower
Creek through the crossing of four streams.
• Disturbance of approximately 0.1 acres of wetland.
The proposed project will not displace any residents or businesses. No adverse impacts will
occur to air quality, long-term water quality, cultural resources, federally protected species,
hazardous material sites, or known underground storage tanks.
8. Coordination
Federal, state, regional, and local agencies have been consulted during this environmental
study. A scoping letter, identifying the project and requesting comments, was distributed to
the following agencies:
• U.S. Army Corps of Engineers
• U.S. Fish and Wildlife Service
• U.S. Environmental Protection Agency
• N.C. Department of Cultural Resources
• N.C. Department of Public Instruction
• N.C. Department of Environment, and Natural Resources

Project Description
1.1 General Description of Proposed Project
The City of Lenoir is proposing to extend McLean Drive (SR 1180) from its current
intersection with US 321 to the intersection of Hibriten Drive (SR 1178) and Haigler Road
(SR 1711) (see Figure 1-1). The proposed roadway will begin at US 321 as a divided four-
lane roadway with curbs and gutters extending for approximately 1500 feet before tapering to a
two-lane roadway with grassed shoulders. The proposed McLean Drive Extension is
approximately 0.98 mile in length and will include two (2) intersections to provide commercial
and residential access to adjacent lands.
1.2 Characteristics of Existing Project Area
The project area is located in the City of Lenoir in Caldwell County. The southern terminus is
US 321 and the northern terminus is SR 1178, Hibriten Drive. Zoned primarily for residential
uses with commercial use at the proposed intersection of US 321 nd McLean Drive, the
project area is currently heavily wooded, vacant land. The top aphy of the area varies from
rolling hills to hilly with cross slopes typically ranging from 10 percent to 25 percent. Valleys
containing stream channels periodically split the landscape. A commercial development is
currently under construction at the intersection of US 321 and the proposed McLean Drive
extension.
US 321 is a four-lane divided highway running north-south along the east side of the City of
Lenoir with minor commercial development bordering both sides. Access to these commercial
developments is by driveway connections to US 321.
Hibriten Drive (SR 1178) is a local two-lane thoroughfare running north-south parallel to
US 321 and connecting NC 18 to the north to US 321 to the south. Adjoining lands are
generally residential with most houses located along the roadway. The land behind the homes
is vacant land. The roadway is used as a bypass around the US 321/NC 18 intersection.
1
n
L
Hibriten Road intersects US 321 approximately 1.2 miles south of the proposed project and NC
18/NC 90 approximately 1000 feet east of the US 321/NC 18/NC 90 intersection.
Commercial development is currently under construction at the US 321 and the proposed
McLean Drive Extension intersection. Residential development exists on Hibriten Drive (SR
1178) at the east end of the proposed extension. There is no existing development along the
route of the proposed extension.
A 12-inch ductile iron water line and a 8-inch ductile iron sanitary sewer has been extended
approximately 1200 linear feet along the proposed route from the intersection with US 321.
There are no additional existing utilities along the route of the proposed extension.
No rail crossings are located in the project area.

Purpose and Need

11

2.1 Project Status
The project is listed in the 2000-2006 NCDOT Transportation Improvement Program (TIP) as
TIP No. U-3813. Construction is scheduled to begin in Fiscal Year (FY) 2000.
2.2 Traffic Volumes and Level of Service
The projected annual average daily traffic (AADT) volumes on McLean Drive (SR 1180)
range from 1700 vehicles per day (VPD) in 1998 to 21,000 vehicles per day (VPD) in 2025.
These projections are based on the Caldwell County Urban Area TRANSPLAN computer
model. (See Figures 2-1 through 2-4). The existing level of service (LOS) for intersection of
US 321 and McLean Drive is level B. At this level, the average travel speeds drop due to
intersection delay and inter vehicular conflicts. Average travel speed remains at approximately
70 % of free flow speed. The projected LOS for the intersection in the 2025 design year AM
peak is level E. At this level, McLean Drive Extension would be functioning at or near 100%
of the proposed design capacity. Traffic flow will be characterized as unstable, with average
travel speeds at 33% of free flow speed and with continuous backup on approaches to
intersections.
The projected LOS for the intersection of McLean Drive Extension (SR 1180) and Hibriten
Drive (SR 1178) is level C in the 2025 design year. At this level, this intersection would be
functioning stable. Longer queues at signals will result in lower average travel speeds. The
average travel speeds will be approximately 50% of free flow speeds.
2.3 Benefits to the State, Region, and Community
This project will provide additional access for the proposed development that will occur in the
project area. The intersection with US 321 will provide a safer more efficient method of
traffic control for the commercial area at US 321. The extension will also reduce congestion at
the US 321/US 64 intersection. With the anticipated growth in this region, improvements to

McLean Drive (SR 1180) will be an important part of the future transportation network in the
region, which includes US 321, and NC 18/90 by providing access to areas proposed for
residential and commercial development. The proposed project is compatible with the City of
Lenoir's land use and transportation planning and is included in the NCDOT Transportation
Improvement Program.
2.4 Summary of Project Need
The extension of McLean Drive (SR 1180) is proposed by the City of Lenoir to provide an
acceptable level-of-service for projected traffic volumes for planned commercial and residential
development. The extension is needed to accommodate projected traffic volumes, to improve
access to commercial development currently under construction along US 321 and to provide
additional access to lands planned for future commercial and residential development. The
proposed extension will help reduce traffic congestion at the US 321 and US 64 intersection.
The project is anticipated to provide access for approximately 300 proposed single-family
dwelling units and approximately 300,000 square feet of retail space.

Chapter 3
Alternatives Considered
Two alternatives were considered for the proposed project: the No-Build Alternative and the
Build Alternative. Through identification of environmental features and preliminary design,
the most practicable alignment for extending McLean Drive (SR 1180) was developed. The
preferred alignment is preliminary and will be further refined during final design.
3.1 No-Build Alternative
The No-Build Alternative would avoid negative impacts to the natural environment and land
uses within the area of proposed construction. However, the No-Build Alternative would not
fulfill local land use and transportation planning objectives for the area.
3.2 Build Alternative
The Build Alternative is the proposed extension McLean Drive (SR 1180) from US 321 to
Hibriten Drive (SR 1178). The improvements will provide an adequate level-of-service for
local area citizens through the year 2025 for planned residential and commercial development
in the area. Both through traffic and turning traffic will move efficiently along the roadway.
Disadvantages of the Build Alternative consist of short-term inconvenience during construction
of the proposed intersections with US 321 and Hibriten Drive (SR 1178) due to the presence of
construction equipment adjacent to the existing roadways. The proposed project will not
displace any residences or businesses and will not have a substantial impact on natural
resources. The benefits of the extension of McLean Drive (SR 1180) include improving traffic
safety and providing convenient access for future residential and commercial development, and
allowing the development of vacant land which in turn will add to the tax base for the City of
Lenoir.

3.2.1 Alignments Considered
Alignments for the extension were considered during planning and functional design. The
potential alignments primarily considered the topography of the land.
To determine the preferred alignment, the following objectives were addressed:
• Provide at-grade intersection at US 321 and NC 1178 (Hibriten Drive)
• Provide smooth transition to the existing roadway at NC 1178 (Hibriten Drive)
• Direct Hibriten Drive traffic to the McLean Drive extension by making McLean Drive and
Hibriten Drive a continuous roadway.
• Provide at-grade perpendicular connections for the proposed residential and commercial
development
• Balance earthwork by minimizing cuts and fills
• Minimize impacts to the natural environment, including one forested wetland and existing
stream crossings.
The most practicable alignment was developed into functional design plans (included in
Appendix B). The alignment shown was determined to be the only practicable design to meet
the project's objectives.
3.2.2 Preferred Alternative
3.2.2.1 Type of Improvement
The Preferred Alternative is the extension of SR 1180 (McLean Drive) as a four-lane divided
roadway with additional turning lanes for access to the commercial shopping area and turning
beginning at the US 321 intersection. The roadway will continue for approximately 1500 feet
and then taper to a two-lane roadway extending northeasterly from the end of the four-lane
section to its intersection with SR 1178 (Hibriten Drive). The Extension will merge into the
two-lane Hibriten Drive (SR 1178) at the northern project terminus and will continue north as
Hibriten Drive.

ui

Hibriten Drive (SR 1178) is a local thoroughfare running north/ south parallel to US 321. It
intersects US 321 approximately 3400 feet south of the intersection of McLean Drive (SR
1180) and the proposed project. Hibriten Drive (SR 1178) will tie into McLean Drive at a
proposed "T"-type intersection and continue as a two-lane roadway to the existing intersection
with US 321.
Functional plans for the preferred alternative are shown in Appendix B. The four-lane

u
roadway will consist of a 48 foot wide divided pavement with curbs and gutters. Additional
turn lanes will be provided at the intersections with the proposed commercial and residential
areas. The two-lane roadway will consist of a 24-foot wide pavement with grassed shoulders.
3.2.2.2 Typical Section
As shown on Figure 3-1, the typical section of the McLean Drive Extension through the areas
of existing and planned commercial development will be a four-lane median-divided facility
consisting of four (4) 12-foot lanes with a 24-foot wide grassed median. Curbs and gutters will
be built along this section to minimize right-of-way requirements.
As shown in Figure 3-2, the typical section of the Extension through the area proposed for
residential development will be a two-lane section consisting of two (2) 12-foot lanes with 8-
foot shoulders of which four (4) feet will be paved. The right-of-way for this section will allow
the McLean Drive Extension to be widened to a four-lane divided facility in the future.
3.2.2.3 Right-of-Way
The proposed right-of-way width will vary from 100 feet to 112 feet between US 321 and the
first proposed intersection and approximately 100 feet from that intersection to Hibriten Drive
(SR 1178) with additional right-of-way at intersections. The proposed project will require
approximately 11.9 acres of right-of-way. Temporary construction easements will be required
along the proposed roadway throughout its length, a total of 3.3 acres on the north side and 6.8
acres on the south side of McLean Drive Extension (SR 1180). In addition, 0.2 acres along
Hibriten Road will be required for temporary construction easements.

3.2.2.4 Horizontal and Vertical Alignment
The proposed horizontal curves range from approximately 7.75 degrees to 10 degrees.
Proposed vertical grades range from 2.5 percent to 9 percent.
3.2.2.5 Proposed Design Speed
The design speed for the McLean Drive Extension (SR 1180) will be 40 miles per hour. The
proposed speed limit will be 35 miles per hour.
3.2.2.6 Bikeways/Sidewalks
The proposed McLean Drive Extension (SR 1180) will serve local traffic from the proposed
residential development along the roadway and as a connector road between US 321 and
Hibriten Drive (SR 1178). Because of the topography and the potential for many access points
on both sides of the roadway, bicycle uses are limited. No bicycle facilities are planned as part
of the improvements. A sidewalk is planned along the south side of the roadway for
approximately 900 feet through the commercial section near US 321.
3.2.2.7 Access Control
There is no access control planned through the areas zoned for proposed residential
development. Access control through the commercial area will be exercised by designated
intersections and the installation of a median and turning lanes.
3.2.2.8 Intersection Treatment
Three (3) at-grade intersections are proposed on this extension of McLean Drive (SR 1180).
Signalized control will occur only at the existing US 321 intersection. A right turn lane will be
added on US 321 northbound, and a left turn lane will be added on the southbound lanes. A
left turn lane will be added on existing McLean Drive (SR 1180) on the west side of the US
321 intersection.

' 3.2.2.9 Utilities
A 12-inch ductile iron water line and a 8-inch ductile iron sanitary sewer has been extended
' approximately 1200 linear feet along the proposed McLean Drive Extension (SR 1180) from
the intersection at US 321. There are no additional existing utilities along the route of the
' proposed Extension. The water line and sewer line is to provide service for proposed
development in the area.
3.2.2.10 Drainage Structures .
The following drainage structures will be located in the project area:
1. A 72-inch pipe culvert at the US 321 intersection conveying a USGS blue line stream
' under the proposed roadway.
2. A 60-inch pipe culvert near the end of the commercial portion of the project,
approximately station 6 + 50, carrying an unnamed tributary to Lower Creek.
3. A 72-inch pipe culvert located along the residential section, approximately station 21 +
00, carrying a USGS blue line stream that is an unnamed tributary to Lower Creek.
' 4. A 36-inch pipe culvert located along the residential section at approximately station 42
+ 50, carrying an intermittent stream.
3.2.2.11 Permits
Section 401 of the Clean Water Act requires each state to certify that state water quality
standards will not be violated for activities that: (1) involve issuance of a federal permit or
license or (2) require discharges into "waters of the United States." Accordingly, a 401 Water
Quality Certification will be required by the N.C. Department of Environment and Natural
Resources - Division of Water Quality. In addition, Section 404 of the Clean Water Act
requires permitting from the U.S. Army Corps of Engineers for activities that encroach into
' jurisdictional wetlands or "water of the United States." Approximately 1290 linear feet of
culvert will be installed in existing streams or intermittent stream channels in order to allow the
' roadway to cross those streams. These stream crossings will require either Nationwide Permit
14, Roadway Crossings, or Nationwide Permit 26, Headwaters and Isolated Water Discharges.
The final permit decision will be at the discretion of the Corps of Engineers. In addition,

Social and Environmental Consequences

n

4.1 Land Use Impacts
The existing land use is the area of the proposed McLean Drive Extension (SR 1180) is
undeveloped forested land. The undeveloped land adjacent the proposed McLean Drive
Extension is planned for residential development. The residential development will consist of
300 single-family home sites. Commercial development at the intersection of US 321 is under
construction. Commercial development is planned at the intersection of US 321 that includes
300,000 square feet of commercial retail space.
Approximately twelve acres of existing woodlands will be cleared for the right-of-way for the
proposed Extension (See Figure 4-1). The turning lanes added along US 321 will impact only
existing grassed or concrete median or shoulders. A portion of the existing Hibriten Drive
(SR 1173) will be reconfigured to intersect the proposed roadway.
4.2 Neighborhood Impacts
The proposed extension of McLean Drive (SR 1180) will not cut off any neighborhoods or
local streets. The improvements will be integrated into the current and proposed transportation
network. Access will not be controlled along the roadway except through the commercial
area. There are no established communities within the project area that would be affected by
the proposed extension.
Executive Order 12898 (Federal Actions to Address Environmental Justice in Minority
Populations and Low Income Populations) requires a review of census data to determine
whether any minority or low-income populations will receive disproportionately high and
adverse human, health or environmental impacts as a result of this project. No minority or
low-income populations will be affected by direct or indirect impacts of the proposed project,
since the land over which the roadway is to be constructed is vacant woodland.

4.3 Relocation Impacts
Based on field reconnaissance the proposed project will not require relocation of any
residences or businesses.
4.4 Community Facilities
No community facilities are located in the project area.
4.5 Utilities
A 12-inch ductile iron water line and a 8-inch ductile iron sanitary sewer has been extended
approximately 1200 linear feet along the proposed route from the intersection with US 321.
There are no additional existing utilities along the route of the proposed extension.
4.6 Economic Impact
The McLean Drive Extension (SR 1180) will be used primarily by residents of the future
residential development, by shoppers to the commercial development, and by commuters
seeking an alternative to the US 321/NC 18/NC 90 intersection. Improving access will have a
positive impact on the local economy. Commuters to the new commercial development will
have access to the area from a roadway other than US 321. Users of the proposed roadway
will benefit from reduced travel time and reduced congestion.
4.7 Historic Architectural and Archaeological Resources

7
U

This project is subject to review pursuant to North Carolina General Statue 121-12 (a) that
requires that if a state action will have an adverse effect upon a property listed in the National
Register of Historic Places, the North Carolina Historical Commission will be given an
opportunity to comment.
There are no historic architectural properties listed in the National Register of Historic Places
located in the project's area of potential effect.
12

i
' An archaeological survey for the proposed McLean Drive Extension resulted in the
identification of five (5) previously unrecorded archaeological sites. These sites indicate that
the project area was inhabited as early as 3000 B.C., or possibly earlier, by Native Americans
and continued to be utilized by later populations, including Euroamericans, up through early
twentieth century. The Deputy State Historic Preservation Officer (Appendix A) concurred in
a memo dated June 5, 1998 that none of the four sites identified within the right-of-way or the
construction easement retain sufficient integrity to yield information important to history or
prehistory, and are not eligible for inclusion in the National Register of Historic Places. The
! remaining site is located outside the boundaries of the project and will not be impacted by the
project.
Therefore, the project will have no effect on historic architectural or archaeological resources.
Based upon the recommendation of the Deputy State Historic Preservation Officer, no
additional historic structure nor archaeological survey or investigation is warranted with the
project.
4.8 Air Quality
' The U.S. Environmental Protection Agency (EPA) has identified six pollutants for tracking air
quality. These six pollutants are: particulate matter (PM-10), sulfur dioxide (SOD, nitrogen
' dioxide (NO2), carbon monoxide (CO), ozone (03), and lead (Pb). Mobile sources (principally
vehicular traffic) are linked to the emission of carbon monoxide and, to a lesser extent,
nitrogen dioxide and ozone. Recent nationwide estimates indicate that more than 50 percent of
all CO emissions are from mobile sources. Particulate matter, lead, and sulfur dioxide
I emissions are generally associated with stationary sources and industrial activities.
' CO is the most commonly occurring air pollutant generated by mobile sources. It is a
colorless gas produced from incomplete combustion of carbon-containing fuel. CO is a
' potentially fatal gas that affects the oxygen-carrying capacity of blood. At low concentrations,
mental function, vision, and alertness are affected.
13
1
Ambient air quality is determined by measuring ambient pollutant concentrations and
comparing the concentrations to the corresponding standard. "Ambient air" is defined by EPA '
as "that portion of the atmosphere, external to buildings, to which the general public has
access." The EPA has established National Ambient Air Quality Standards (NAAQS) for the
six previously identified pollutants; PM-101 COI, 03, SO2, N02 and Pb. The ambient air
quality standards are classified as primary standards, secondary standards, or both. The
primary standards were established allowing an adequate margin of safety for protection of
public health. Secondary standards were established with an adequate margin of safety to
protect the public welfare from adverse effects associated with pollutants in the ambient air.
In protecting public welfare, air pollution effects on the following are considered; soil, water,
crops, vegetation, man-made materials, animals, wildlife, weather, visibility, climate,
property, transportation, economy, personal comfort, and well-being. The scientific criteria ,
upon which the standards are based are periodically reviewed by the EPA, and the standards
are re-established or changed based upon findings. The current national primary and '
secondary ambient air quality standards are summarized in Table 4-1.

' The most prevalent pollutant emitted from motor vehicles is CO. For this reason, the analyses
presented are concerned with determining the projected 2025 CO levels in the vicinity of the
I project.
To determine the CO concentration at a receptor, two concentration components must be used:
local and background. The local component is predicted from dispersion modeling and due to
' CO emissions from motor vehicles operating near the receptor locations. The background
component is the ambient CO level, which the air is estimated to be 1.8 ppm, a typical value
' for rural North Carolina areas. These two components were added together to determine the
total CO concentration for comparison to the NAAQS.
' In this assessment, the line source computer model CAL3QHC was used to predict the local
CO concentration components. The CAL3QHC model is a dispersion computer model
' developed for EPA. Based on the assumption that vehicles at an intersection are either in
15
motion or in an idling state, the program is designed to predict air pollution levels by
combining emissions from both moving and idling vehicles.
CAL3QHC uses emissions factors generated by EPA's approved model MOBILE 5A. To
evaluate the maximum impact of the proposed project on ambient CO concentrations, worse-
case inputs were used in the modeling. The objective is to develop a worst-case scenario to
predict the highest CO concentration that could reasonably occur as a result of the proposed
project. A summary of the CAL3QHC input parameters are tested in Table 4.2

In 2005, the maximum one-hour CO concentration at the intersection of McLean Drive
Extension (SRI 180) and US 321 is predicted to be 2.9 ppm while the 2025 concentration is
predicted to be 3.1 ppm.
Comparison of the predicted CO concentrations with the NAAQS indicates that no violation of
the one-hour CO standard of 35 ppm will occur. Using a persistence factor of 0.61 the
maximum eight-hour CO concentrations on the proposed Extension is predicted to be 1.8 ppm
16

' for 2005 and 1.9 ppm for 2025, below the eight-hour standard (9.0). Therefore, the proposed
Extension will not exceed NAAQS.
4.9 Noise
' Traffic noise results from the vehicle's engine, exhaust, and drive train, and from the tire-
roadway interaction. The actual magnitude of sound is caused by short-duration fluctuations
' in atmospheric pressure. These fluctuations are called sound pressures. Since the range of
sound pressures varies greatly, a logarithmic relationship is used to reference sound pressures
L to common pressure. This relationship is defined as the sound pressure level and is measured
in decibels (dB). The decibel is often modified by frequency weighting curves (A,B,C, or
i D). Vehicle noise levels are commonly modified by the A-weighting curve which correlates
very well with human response to noise. Sound levels using the A-weighting curve are
expressed in dBA.
' Sound pressure levels in this report are expressed as the hourly Lq, or equivalent sound level,
which is the level of dBA of constant sound that would contain the same acoustic energy in an
hour as the actual sound, which varies considerably over time. In other words, the fluctuating
sound levels of traffic noise are represented in terms of a steady noise level with the same
energy content.
1 To determine if highway noise levels are compatible with various land uses, the NCDOT has
developed noise abatement criteria and procedures in accordance with Title 23 Code of Federal
Regulations (CFR), Part 772, U.S. Department of Transportation, Federal Highway
Administration (FHWA), "Procedures for Abatement on Highway Traffic Noise and
Construction Noise." A summary of the FHWA Noise Abatement Criteria (NAC) for various
land uses is presented in Table 4-4.

For this project, all of the identified receptors are residential or commercial (categories B and
Q. However, the design L,,q of 67 dBA (category B) was used for the link of roadway
analyzed. No category A or D receptors were identified.
One measure of noise impact is the extent of the 67 dBA noise level contour that corresponds
with the noise abatement criteria for land use category B (residential). The extent of the 67-
dBA noise contour line can be used to assess the expected impact of traffic noise.
As defined by FHWA, a receptor may be impacted if the noise level approaches or exceeds the
FHWA NAC. "Approach or exceed" is defined as being within 1 dBA of the standard by the
NCDOT; therefore, the appropriate contour line is 66 dBA. This contour line is the distance
from the centerline of the proposed project to the contour line where a noise level of 66 dBA is
predicted to occur. Table 4-5 details the modeled noise contour line for the proposed roadway.

Based on the predicted noise contours, the noise impact is expected to be minimal. The 66
dBA noise contour line ranges from within the right-of-way to 62 feet from the centerline. The
worst-case noise prediction, in 2025, for the 66 dBA level is 12 feet outside the right-of-way,
which is considerably closer than local property setback regulations would allow a building or
structure. Based on the analysis, the proposed project will not impact any existing or proposed
residential receptors. No abatement measures are proposed.
Although high equipment noise levels are expected to be the main contributor to the
construction activity noise emission, noise impacts during construction are of short duration.
Peak noise levels from highway construction equipment is measured at a distance of 50 feet
away may vary from 70 to 100 dBA. The major source of noise will be from earth removal,
handling, grading, pile driving, and paving. General construction noise impacts that can be
expected are temporary speech interference for passersby and those individuals working on or
near the project. Such noise will be limited to day light hours as much as possible.
4.10 Natural Resources
Based on literature reviews, aerial photograph interpretation, and field reconnaissance, the
existing natural environmental and potential impacts of the project were assessed. The results
are detailed in the "Natural Resources Technical Memorandum" (September, 1998) and
summarized in the following sections.
19
4.10.1 Terrestrial Plant Communities
The distribution of plant communities in a landscape is the result of topographic positioning,
climate, soil characteristics, hydrologic influence, and past and present land-use practices. The
proposed road alignment transverses a natural area between US 321 and the SR 1178 (Hibriten
Drive). An adjacent area bordering US 321 has been cleared for construction of a shopping
center. Most of the road will cut through forested land. Within the last ten years, logging
roads were cut to facilitate removal of timber.
The vegetative communities found along the proposed road alignment consist of oak-hickory
forests on the ridges, grading into beech on the slopes and alluvial forest at the stream
crossings. Due to the selective logging of the forest within the last ten years, there is a
considerable amount of small growth. Pine trees were not present except on the ridge tops.
Yellow poplar (Liriodendron tulipifera), oak (Quercus), and maple (Acer) were the most
common trees in various successional stages. Table 4-6 at the end of this section lists the
species encountered during the field survey.
Vegetation on the ridge tops was predominately red oak (Quercus rubra) and hickory (Carya
sp.) in the canopy. The understory was densely populated with red maple (Acer rubrum),
yellow poplar (Liriodendron tulipifera), white and red oak (Quercus rubra and alba), dogwood
(Corpus florida), and a few pine (pinus strobus). Herbaceous growth was very sparse.
Sawbriers (Smilax sp.) were abundant, partridge berry (Mitchella repens) was common, and
occasionally heartleaf (Hexastylis arifolia) was found. Other than the presence of partridge
berry (Mitchella repens), all vegetation was common to drier forest communities.
The proposed road will cross four streams, one wet weather conveyance, and one seep. In the
ravines associated with the streams, the forest was comprised of species preferring moist
conditions, such as sweet gum (Liquidambar styraciflua), red maple (Acer rubrum), and
musclewood (Carpinus caroliniana). Only one hemlock (Tsuga Canadensis) was noted at
stream 4 and sycamores (Ficus sycomorus) were common below stream crossings 1 and 2, see
20

1

Figure 4-2 in Section 4.10.5 for stream locations. Willow (Salix) was found at stream 1 and
stream 3.
4.10.2 Wildlife Habitat
The project area contains excellent habitat for deer, small game, other small mammals, birds,
and reptiles. During the survey, deer sign (tracks and scrapings) were observed throughout.
Raccoon tracks were also observed around all the stream areas. Disturbed leaf litter,
characteristic of turkey scratchings, was seen in the ravine at stream 4. Game trails were
common throughout the area.
In addition, thrush, brown thrasher, and mourning doves were observed. The area offers
excellent shelter and nesting for species of woodland songbirds. Signs of woodpecker activity
were noted and woodpeckers could be heard during the site visit.
Excellent reptile habitat is also present. Eastern fence lizards were seen throughout the area on
downed timber. A black racer was encountered near stream 2. Both shelter and food sources
were abundant.
4.10.3 Habitat Reduction
Habitat fragmentation occurs when parcels of habitat are isolated and made less suitable for
wildlife. This impact decreases the species richness and diversity within the area. The degree
of impact depends on the size and isolation of the parcels being fragmented and the sensitivity
of the species. Plant and animal species with large home range requirements, specific
microhabitat requirements and poor dispersal abilities are most affected by habitat
fragmentation.
Positive impacts from the road corridor will include an increase in forest edge, thereby
creating more feeding habitat for prey and predator species. Negative impacts include
bisection of the wooded area, thus creating a likelihood of road kills. There will be a loss of
habitat for both aquatic species and terrestrial species to the extent that ravines are filled and
21

the area is covered by roadway. Approximately twelve (12) acres of habitat will be lost to
roadway.
4.10.4 Protected Species
Throughout the United States, rare plant and animal species are protected by federal and state
laws. The endangered Species act of 1973 (16 U.S.C. 1531-1943) mandates that federal
agencies ensure that any actions authorized, funded, or carried out by that agency do not
jeopardize the "continued existence" of listed species or result in the destruction or adverse
modification of critical habitat (16 U.S.C. 1536). Proposed species are offered "limited
protection" under Section 7 (A)(3) of the Endangered Species Act of 1975, as amended by
Congress in 1988. North Carolina laws grant protection to rare plants and animals that are
endemic to the state or whose populations are in severe decline (NCES Act 6.5 113-351 to
113.337 and the N.C. Plant Protection and Conversation Act of 1979).
A list of state and federal special concern, threatened, and endangered species, January 2000,
is provided in Table 4-7 at the end of this section for the project and surrounding areas. The
US Fish and Wildlife Service, the North Carolina Natural Heritage Program, and the North
Carolina Wildlife Resources Commission were contacted to obtain current listings of and
concerns about threatened and endangered species. None of these species listed were reported
from the proposed project area.
Most of the species listed by both state and federal agencies are found in higher elevations and
would not likely be found in the project area. Species, which might be found but the habitat
was very marginal, included the black billed cuckoo, purple fringeless orchid, and trailing
wolfsbane. None of these species was found.
Species for which marginal to fair habitat was present included dwarf ginseng, dwarf
chinquapin oak, riverbank vervain, and butternut. None of these species was noted.

Those species for which suitable to good habitat was available included dwarf heartleaf, sweet
pinesap, Diana fritillary, and the Allegheny woodrat. The last three were not found. The
heartleaf is discussed is below.
Federal Endangered Species: Spruce-fir moss spider, Microhexura montivaga. This spider
is endemic to the mountains of North Carolina and Tennessee at higher elevations. Its habitat
is the moss growth on spruce and fir trees.
BIOLOGICAL CONCLUSION: No habitat was available in the project area for the spruce-
fir moss spider. Therefore, there will be No Effect on this species.
Federal Threatened Species: Heller's blazing star, Liahis helleri. Heller's blazing star
belongs to the asterceae. It is perennial herb. Growing up to 1 + meters. Leaves are
alternate, cauline and basal. Flowering heads are in spikes, with corolla tubes lavender. The
flowering season is late July to August and September to October. It closely resembles Liatris
turgida and Liatris graminifolia. The differentiating factor is the length of the pappus
compacted to the corolla tube. Habitat consists of ledges, cliffs, rocky woods, and high
elevation rocky summits.
BIOLOGICAL CONCLUSION: No habitat was available in the project area. This species is
considered extant in Caldwell County according to the NC Natural Heritage Program.
Therefore, a finding of No Effect is considered warranted for this species.
Federal Threatened Species: Dwarf-flowered heartleaf, Hexastylis naniflora. This plant, a
member of the Aristolochiaceae, is a perennial herb with simple evergreen leaves. The leaves
are cordate to orbicular-cordate, 4-6 cm long or wide with lobes usually 1/4 or less than the
total length. The flowers are perfect, 3-merous, petals absent, calyx tube cylindrical and
reticulate ridged within. The distinguishing feature of this species is the calyx tube which is
less than 1 cm long. It blooms in April to early May.
23

Habitat for this species is acidic soils along bluffs and adjacent slopes, boggy areas next to
streams and creek heads, and along the slopes of nearby hillsides and ravines. It often occurs
in stands of mixed hardwoods with an understory of mountain laurel or rhododendron. It has
been found growing in sandy loams of the Pacolet, Madison, and Musella series.
BIOLOGICAL CONCLUSION: Habitat is available for Hexastylis species in the project
area. Pacolet sandy loams occurs in the ravine at stream 3. During the initial field survey,
two species of heartleaf were observed. The most common was Hexastylis arifolia, found
throughout the project area. A second species of heartleaf was found in the ravine at stream 3.
The leaf was dark green with white along the veins, reinform to orbiculate in shape. Based on
leaf characteristics, it appeared to be Hexastylis shuttleworthii, the presence of white along the
veins being a distinguishing characteristic of this species. A subsequent field survey was
undertaken in May, 2000 to observe the plant flowers. This survey confirmed the species to
be Hexastylis shuttleworthii. A summary of the survey from Fish and Wildlife Associates, Inc.
is included in Appendix A. No other species of heartleaf were found. Therefore, a finding of
No Effect is considered warranted for this species.
4.10.5 Aquatic Resources
Aquatic resources of perennial or flowing streams were characterized by measuring basic water
quality parameters, describing the composition of streambed substrates and the riparian
vegetation, and observing aquatic life. Dissolved oxygen and temperature were measured with
a Yellow Springs Instruments Model 55/12 FT meter. Conductivity was measured with a
Beckman model 2A-RA meter and pH with a HACH Model 17-F test kit. Basic water quality
parameters for the three flowing streams are given in Table 4-8 at the end of this section.
Substrates were categorized according to diameter and ranked by dominance. Riparian
vegetation was identified to species an evaluation of canopy coverage made. An observation of
fish presence and a cursory assessment of macroinvertebrates (benthos) were conducted.
The streams in the Project Study Area are too small and shallow to support fisheries. The
Catawba Basin Water Quality Management Plan, 1995 did not include the project's streams.

The nearest creek evaluated was Lower Creek and the state's findings are summarized in the
Pre-Field Report for that publication.
Short term ecological impacts to the existing aquatic communities will be due primarily to the
construction of the highway over the streams and resulting land disturbance. All streams will
potentially receive impacts from sedimentation as a result of land disturbance and channel
modification activities. Short term effects on the aquatic resources include increased water
turbidity and sedimentation. Turbidity affects sight feeding organisms, abrades gill filament,
and increased water temperature. Sedimentation reduces or eliminates the available habitat for
many species of macroinvertebrates. No fish were seen in the immediate project area, but
effects could extend to populations existing downstream.
Longer term effects include disturbance of the streambed and alterations in stream hydrology.
The streambed will be modified to accommodate the culvert extensions at each stream crossing
necessary for the expanded roadbed. Changes in hydrology include increased discharge, which
results from the greater area of impermeable surface associated with the additional pavement.
Increased discharge, especially following heavy rainfall events, scours the streambed,
accelerates bank instability, and modifies existing riffle, run and pool habitats.
Impacts to the aquatic resources will be reduced by limiting the duration of in-stream activities
during channel modification and by implementing erosion control best management practices.
Erosion control measures will include sediment fences, retaining ponds, and revegetation.
4.10.6 Streams
A total of six (6) streams were identified during the field survey. Stream 1, a U.S.G.S. blue
line stream, is located immediately parallel to US 321 at the beginning of the project. Its
source appears to be the drainage beside and underneath US 321 and the commercial properties
' in the area. The discharge flows north along US 321 until it enters Lower Creek. Most of the
riparian area has been cleared except for one side of the stream north of the interchange with
' US 321 where some yellow poplar had been allowed to grow and provided limited cover.

Substrates were dominated by cobble and boulders with sand in the small pool area.
Everything in the substrate was coated with a layer of fine clay (red) probably due to the
aquatic life. The depth of the water was very shallow - 0.2 feet at the deepest pool and had no
large pools or riffles. The stream width was estimated at 3 feet. The stream had been
channeled in the past to drain storm water from US 321. No fish or benthos was observed in
this stream. Crayfish and ladybugs were observed in the vicinity of the creek. Rocks, logs,
and leaf packs were sampled for benthos. Riparian vegetation observed included sawbrier,
ragweed, yellow poplar, pokeweed, smartweed, coneflower, ceresea, thistle, dayflower,
primrose, avens, milkweed, joe pye weed, partridge pea, mullein, assorted morning glories
and jewel weed. Approximately 205 linear feet of stream will be impacted.
Stream 2 is located about 500 feet north and east of Hwy 321. This stream is not shown on the
U.S.G.S. map. The stream arises in an undeveloped area immediately adjacent to the
proposed project. Most of this area has been cleared for commercial development. At the
project crossing and along the downstream border, the riparian zone was cleared for a distance
of 50 feet. Further upstream the riparian zone is composed of mixed hardwoods, mainly sweet
gum. Approximately 50 percent of the stream was shaded. Substrates were predominately
sand with an underlay of gravel. The stream width was 1 foot to 2 feet average and the depth
was 0.1 feet. Habitats were dominated by sand flats, with a good deal of brush and tree debris
covering the stream in the cleared crossing. Basic water quality parameters indicated
conditions suitable to sustain aquatic life. No fish were observed in this stream. A cursory
benthic survey of the sand, gravel, and leaf packs found stoneflies, snails, and leeches, All
organisms were very small at the time of the field survey. Water striders were present on the
surface. Riparian vegetation included spicebush, sweetgum, sycamore, sourwood, sawbrier,
multifloral rose, and yellow poplar. Approximately 432 linear feet of stream will be
impacted.
Stream 3 is located mid-way between the beginning of the project at US 321 and the terminus
at Hibriten Drive (SR 1178). It is shown on U.S.G.S. maps as a blue line stream. The stream
drains an area that had been logged in the past 10 years, but otherwise was undisturbed.
26

u

' Shading of the stream was at 75 percent. Substrates were predominately sand with smaller
riffle areas of gravel and cobble. Physical habitats were low gradient runs and riffles. The
stream bank showed undercuts of up to 4 feet above the current water level. The stream width
was 3 feet and the depth averaged 0.2 feet. Basic water quality parameters indicated
conditions suitable to sustain aquatic life. No fish were observed in this stream, probably due
to low flow conditions in this small stream. Benthos survey of rocks, sandy areas and leaf
packs found a good number and variety of organisms, especially in a rocky riffle area.
Mayflies, stoneflies, one caddisfly case, and snails were all observed. On the downstream side
' of the project crossing, vegetation representative of wetlands was observed on the northeast
side. This is discussed further in the Wetlands Determination Section below. Riparian
' vegetation at the project crossing included spicebush, beech, red maple, willow, smart weed,
christmas fern, sawbrier, coneflower, dogwood, laurel, sagitarius, yellow root, black walnut,
yellow poplar, ferns, sedges, stinging nettler, violets, hexastylis, Indian cucumber root, and
musclewood. Approximately 811 linear feet of stream will be impacted.
The wet weather conveyance was located between Stream 3 and Stream 4 intermittent. It
drains from the ridge line north of Stream 3 towards Lower Creek. No defined channel was
' observed and as such no stream will be impacted.
' A seep was observed on the east side of the hill above the intermittent Stream 4, approximately
500 feet from the intersection with Hibriten Drive (SR 1178). There is a distinct channel on
' the uphill side (northeast). Prior to the road cut, the water flow disappeared underground and
reappeared approximately twenty feet above its confluence with Stream 4. Since the cut was
' bulldozed, the water flows across the road and seeps into the ground. There is no defined
channel on the southwest side of the road. No stream will be impacted.
1
Stream 4 is an intermittent stream located about 400 feet from the terminus of the project on
Hibriten Drive. This is not shown on the U.S.G.S. maps. On the day of the field survey,
there was no flowing water present. Downstream there were standing pools of water
' 27

observed, but no flow. Riparian vegetation included sweet gum, christmas fern, hog peanut,
partridge berry, sawbrier, white oak, beech, yellow poplar, bloodroot, heartleaf, privet, poison
ivy, spice bush, American holly, red maple, and rattlesnake fern. Shading was 100 percent of
the stream. Approximately 340 linear feet of intermittent stream will be impacted.
Mitigation for 1,788 linear feet of stream impact will be required by the 401 Certifications
issued by North Carolina Division of Water Quality (DWQ) under the 404 Permit issued by the
U.S. Army Corps of Engineers (COE). The current policy (September 1999) of DWQ
requires compensatory mitigation or restoration of other degraded streams on a 1:1 basis, for
impacts of greater than 150 linear feet to perennial streams. Mitigation for the streams
impacted by this project will be on a compensatory basis.
430.7 Wetlands
Wetlands are defined by the U.S. Army Corps of Engineers (COE) (33CFR 328.3) and the
U.S. Environmental Protection Agency (EPA) (40 CFR 230.0) as:
"those areas that are inundated or saturated by surface or ground water at a
frequency and duration sufficient to support, and that under normal circumstances
do support, a prevalence of vegetation typically adapted for life in saturated soil
conditions. Wetlands generally include swamps, marshes, bogs, and similar
areas."
In accordance with this definition, wetlands must possess three essential parameters:
hydrophytic vegetation, hydric soils, and evidence of hydrology (COE Wetlands Delineation
Manual, 1987) Besides providing valuable habitat for a diverse number of plant and animal
species, wetlands also control floodwaters and erosion, replenish groundwater, filter
contaminants and excess nutrients from runoff, and protect water supplies.
Section 404 of the Clean Water Act requires regulation of the disposal of dredged or fill
material into "waters of the United States," which are both deepwater aquatic habitats and

special aquatic sites, including wetlands (COE Wetlands Delineation Manual, 1987). The
principal administrative agency of the Clean Water Act is the U.S. Environmental Protection
Agency (EPA). The COE has the major responsibility of implementing, permitting, and
enforcing provisions of the Act in cooperation with the EPA and USFWS. Executive Order
11990 requires that new construction in wetlands be avoided to the extent possible and that all
practicable measures be taken to minimize or mitigate impacts to wetlands.
No wetland resources were identified on the National Wetlands Inventory Map within the
project area. During the field survey, two small wetland areas were located in the vicinity of
the Stream 2 and Stream 3 (see Figure 4-2).
The field survey was performed in September 1998 during a period of extremely low water.
Drought conditions prevailed throughout the area. It is safe to assume that conditions noted in
the file, represent the low end of the range of water availability.
Two wetland areas, one adjacent to and one confined within the stream banks of Stream 2, will
be filled. The predominant vegetation in the area was sweet gum, laurel, and sawbrier. Other
woody vegetation such as sycamore, red maple, and yellow poplar were present. Mutliflora
rose and spice bush were present in the understory, but very little herbaceous layer was
present. The area has been disturbed by construction activities associates with the shopping
center and with the bulldozed trail. These areas were delineated by Soil and Environmental
Consultants, Inc. for the shopping center project and are not included in any impacts by this
roadway.
Stream 3, one of the two perennial streams indicated on the USGS map, has several areas of
wetland within the stream banks and one adjacent wetland area fed by seepage. Within the
stream banks small islands, sand bars, and mud flats are exposed and have herbaceous
vegetation growing on them. Various grasses, sedges, jewel weed, and smart weed were the
predominant vegetation. The total area of wetlands within the stream was approximately 0.02
29

acres. These areas will be filled during construction of the road. DEM values are generally
not assigned in areas where the wetlands are confined to the stream itself.
A small wetland area, 0.03 acres, was located outside of the road right-of-way, but within the
slope fill. It appears to be fed by seep, standing water was present and soil was saturated.
Predominant vegetation was smart weed. Other species normally associated with wetland areas
that were observed include willow and arrowhead. The soil map showed the presence of a
small area of Chewacla loam which has hydric inclusions of Wehadkee loam. Classification
according the US FWS (Corwardin 1979) is PEM1B. The DEM value is 16. Total wetlands
impacted by the project are 0.05 acres.
4.10.8 Forest Resources
Potential forest productivity information for the area ranged from 54 for Chestnut Oak in soils
classified HbF to 98 for Yellow poplar in soils classified Wk. The complete site indexes for
the soils in the area can be found in Table 4-10 at the end of the section. The Cecil soils have
slight management concerns for erosion, equipment limitation and seedling mortality. Hibriten
and Pacolet soils have moderate erosion hazards, moderate to severe equipment limitation and
moderate seedling mortality. The Chewacla soils have slight erosion hazard, moderate
equipment limitation and slight seedling mortality. The hydric soils of Wehadkee have slight
erosion hazard, sever equipment limitation and seedling mortality. Species to be planted
include eastern white pine, loblolly pine, and hardwoods for all soils, plus black walnut for
Chewacla. All of these soils require an even-aged management system for natural regeneration
of desirable hardwood species. The majority of the project vicinity is currently being managed
as an unmanaged, cutover woodland. The proposed project would remove approximately 12
acres of woodland out of forest production.
4.10.9 Flood Hazard Evaluation
Floodplain areas are addressed by both federal and state regulations. The objectives of
Executive Order 11988, Floodplain Management, and NCDOT Order 5650.2, Floodplain
Management and Protection, are to avoid adverse impacts due to occupancy and alteration of
30

t

n

u

the 100-year floodplain unless that location is the only practicable alternative. When
floodplain areas are impacted, every effort must be made to minimize the potential risks to
human safety and to property and to minimize negative effects on natural and beneficial
floodplains. There are no designated 100-year floodplains in the area of the McLean Drive
(SR 1180) Extension.
4.10.10 Topography, Soils, and Mineral Resources

The project is located in the Piedmont physiographic province and is characterized by rolling
hills. The rolling terrain of the project area, beginning at US 321, is mostly forested, with
cleared areas at both termini. Moderately heavy commercial development interspersed with
woods and residences is prevalent along US 321 in this area. There area two steep inclines
into drainage areas as the project approaches Hibriten Drive and the end of the project.
Elevation begins at approximately 1200 feet and varies between 1150 and 1300 feet over the
length of the project. At the end of the project near the Hibriten Drive and Haigler Road
intersection, the area is mainly large lot residential.
The soils within the project are dominated by the sandy loams of the Cecil, Pacolet and
Hibriten series. These soils all have concerns about erosion and steepness of slope. Most are
recommended for use as woodlands. There are areas of hydric soils and Wehadkee located
adjacent to Lower Creek, but the project does not cross any Wehadkee soils. Chewacla, which
has inclusions of hydric soils, is also present in the vicinity. The project crosses one area of
Chewacla at Stream 3. Another area of Chewacla is within the project vicinity, but is not in
the project study area. The soil associations are listed in Table 4-9 at the end of this section.
Mineral resources evaluation was completed by reviewing publicly available United States
Geological Survey (USGS) and State of North Carolina documents and a interview/discussion
with the State of North Carolina Geologic Survey (NCGS).
The document "Permitted Active and Inactive Mining Operations in North Carolina as of
November, 1996" NCGS Open File Report 97-1 indicates four mining operations in Caldwell
31

1
County. These operations are sand/gravel or crushed stone mines and quarries. The
operations are not located near the proposed road location. I
The document "Mineral Resources of the Charlotte 1X2 degree Quadrangle, North Carolina
and South Carolina, " USGS Professional Paper 1462 includes part of Caldwell County. '
Geological, geochemical and geophysical data were evaluated and mineral resources were
classified. The assessment program results do not indicate known or potential resource areas ,
present within the proposed subject site.
The North Carolina Geologic Survey through interviews on July 13, 1998 indicates that there
had not been any inquiries or activity in the Lenoir, Caldwell County, North Carolina area in
over 10 years. There is no known mineral resource potential within the proposed subject site.
4.11 Secondary Impacts
Secondary Impacts occur as a result of development induced by a project. McLean Drive ,
Extension (SRI 180) corridor is not. currently developed, but there are plans to construct a
residential development of 300 single-family homes adjacent to the corridor. The land adjacent '
to the roadway will be primarily residential, with the exception of the commercial area at the
US 321 intersection on which will be constructed a 300,000 square foot shopping center. '
Control of land use plans and review of zoning requests will remain the responsibility of local
officials. Existing and future businesses and residents will experience improved access and
commute time as a result of the proposed project.
4.12 Visual Impacts
The site on which the McLean Drive (SR 1180) Extension is to be constructed is primarily
rolling, wooded hills. The main visual impact will be the loss of trees within the right-of-way '
and construction easements. All denuded areas will be replanted with vegetative ground cover
upon completion of construction. ,

4.13 Hazardous Material Sites
A file search was conducted on the project area to identify any potential hazardous material
sites including generators, treaters, and disposers of hazardous wastes, landfills, sewage
treatment facilities, garbage dumps; abandoned service stations with underground storage tanks
(UST's); fuel, oil, and gasoline storage tanks; and lagoons.
The following lists were reviewed by searching Environmental Data Resources, Inc. (EDR)
databases used to access available lists published by the EPA and NCDENR.
a. National Priorities List (NPL)

F,

The NPL is the EPA's database of uncontrolled or abandoned hazardous waste
facilities identified for priority remedial actions under the Federal Superfund
Program. North Carolina also maintains a "state equivalent" to the federal NPL of
Hazardous Waste Sites (HWS).
The proposed project site was not included on the NPL database reviewed, and
there were no NPL facilities listed within a one-mile radius of the site. In addition,
the site was not on the State HWS (SHWS) list reviewed. One SHWS facility,
Lenoir Refinishing Co., was listed within a one-mile radius of the site.
b. Comprehensive Environmental Response Compensation and Liability Act
(CERCLA)
The CERCLA Information System (CERCLAIS) List compiles facilities for which
EPA has investigated or is investigating a release or threatened release of hazardous
substances.
The site was not listed on the CERCLAIS list and no CERCLA facilities were listed
within a one-mile radius to the site.
33
c. Resource Conservation and Recovery Act (RCRA)
The RCRA program identifies and tracks hazardous waste from the point of
generation to the point of disposal. The RCRA database contains reporting facilities
that generates, store, transport, treat, or dispose of hazardous waste.
The site was not listed on RCRA lists and there are no sites listed within a one-mile
radius of the site.
d. State Solid Waste Facilities and Landfills (LF) List
NCDENR maintains lists of active and inactive landfills and disposal sites including
known permitted and unpermitted landfills and dumps.
The site was not on the LF list, nor were there LF facilities within a one-half mile
radius of the site.
e. Leaking Underground Petroleum Storage Tank (LUST) List
The LUST list is a database of tank systems within the State have reported releases
of petroleum storage tank system contents. The site was not on the LUST list, but
there was one site, Dot-Ray's Variety Store, listed on the orphan's summary list
within a one-half mile radius of the site as a LUST.
f. Underground Storage Tanks (UST) List
The UST list is a database of tank systems that are currently operated or have not
submitted closure applications. The site was not on the UST list nor were any
UST's listed within a one-half mile radius of the site.
34

LI

g. Emergency Response Notification System (ERNS)
The EPS ERNS stores information on releases of oil and hazardous substances.
ERNS confirms data from the National Response Center and the EPA.
The site was not linked on the ERNS list and no off-site ERNS incident were listed
within a one-half mile radius of the site.
Areas surrounding the project were observed in the field and evaluated based on EDR records.
Adjacent areas are described as follows:
West - Along US 321 two businesses were noted as having potential to impact the site: 1) an
auto sales/repair shop and 2) a BP gas station and convenience store. Neither property is listed
as a hazardous waste generator, UST or LUST site.
East - Along Hibriten Drive (SR 1178), properties are primarily residential, single family
homes. The residences are not considered to be of environmental concern.
North - Properties are down gradient and are generally residential, business or golf. Activities
to the north are not considered to be of environmental concern.
South - A convenience store, Dot-Ray's Variety Store is located on Hibriten Drive (SR 1178)
is identified in the LUST and orphan summary databases, but not mapped by EDR. The store
is located approximately 1000-2000 feet south/southeast of the site and topographically
upgradient. Based on the distance it is unlikely that petroleum releases from the LUST would
affect the project site. Other properties south include residential, business and a school. No
environmental concerns are expected.
r
Based on the site reconnaissance and regulatory file review, the proposed project will not
' impact any known hazardous material sites or underground storage tanks.
' 35

4.14 Construction Impacts
Short term construction impacts may occur in the areas of water quality, air quality, natural
resources, and noise. The potential impacts can be minimized by careful adherence to
established construction methods. These methods are described below:
• Waste and debris will be disposed of in areas outside of the right-of-way and provided by
the contract, unless otherwise required by the plans or special provisions or unless disposal
within the right-of-way is permitted by the engineer. Disposal of waste or debris in active
public waste or disposal areas will not be permitted without prior approval by the engineer.
Such approval will not be permitted when, in the opinion of the engineer, it will result in
excessive siltation or pollution.
• During construction of the proposed project, all material resulting from clearing, grubbing,
demolition, or other operations will be removed from the project, and disposed of by the
contractor. Any merchantable timber should be salvaged. If vegetation is disposed of by
burning, all burning will 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.
Additionally, trees outside of the construction limits should be protected from construction
activities to prevent skinning tree trunks by use of heavy equipment, exposing roots,
smothering trees from fill dirt around the base, or accidentally spilling petroleum.
• Borrow pits and ditches will be drained as practicable to alleviate breeding areas for
mosquitoes.
• Care will be taken no the block existing drainage ditches.
• There will be strict adherence to the erosion control plan by the contractor, including
limiting areas and duration of exposed earth and stabilizing exposed areas as quickly as
possible. Careful attention to erosion control will be concentrated at creek crossings.

' Measures will be taken to alleviate the dust generated by construction when the control of
' dust is necessary for the protection, safety, and comfort of motorists and nearby residents.
• Noise impacts during project construction are of short duration as measured at a distance of
50 feet. Peak noise levels from highway construction company equipment may vary from
' 70 dBA to 100 dBA. The major sources of construction noise will be from earth removal,
hauling, grading, pile driving, and paving. Passersby and those individuals working near
the project can expect temporary speech interference. Such noise will be limited to
daylight hours as much as possible.

' The Division of Water Quality (DWQ) requests that the following topics be
discussed in the EA/EIS document:
A. Identify the streams potentially impacted by the project. The current stream
classifications and use support ratings for these streams should be included. This
information is available from DWQ through the following contacts:
Liz Kovasckitz -Classifications - 919-733-5083, ext.'S72
Carol Metz - Use Support Ratings - 919-733-5083, ext. 562
' B . Identify the linear feet of stream channelization/relocations. If the original stream
banks were vegetated, it is requested that the channelized/relocated stream banks be
revegetated
C. Identify the number of stream crossings.
D. Will permanent spill catch basins be utilized? DWQ requests that these catch basins
be placed at all water supply stream crossings. Identify the responsible party for
maintenance.
E. Identify the stormwater controls (permanent and temporary) that will be used
F. Please ensure that sediment and erosion control measures are not placed in
wetlands.

A'
I. Please provide a conceptual wetland mitigation plan to help the environmental
review. The mitigation plan may state the following:
' 1. Compensatory mitigation will be considered only after wetland impacts have
been avoided and minimized to the maximum extent possible.
2. On-site, in-kind mitigation is the preferred method of mitigation. In-ldnd
mitigation within the same watershed is preferred over out-of-kind mitigation.
3. Mitigation should be in the following order: restoration, creation, enhancement,
and lastly preservation. -
7. The EA should discuss in detail project alternatives that alleviate traffic problems
' without road extension, such as mass transit and traffic congestion management
techniques.
DWQ is also concerned about secondary wetland impacts. For DWQ to concur
with an alternative in the mountains or the piedmont, DOT will need to commit to full
control of access to the wetland parcels or DOT to purchase these parcels for wetland
mitigation.
Written concurrence of 401 Water Quality Certification niay be required for this
project. Applications requesting coverage under our General Certification 14 or General
Permit 31 (with wetland impact) will require written concurrence. 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.
Please call Cyndi Bell at [phone] if you have any questions on these

SUBJECT: DOT Scoping for McLean Drive Extension, Caldwell County
PROJECT #: 98-0692 & TIP # U-3813
The North Carolina Division of Forest Resources has reviewed the referenced scoping document and offer
the following comments that should be addressed in the EA concerning impacts to woodlands.
1. Woodlands will likely be impacted by the project. Therefore, the total forest land acreage by type that
would be removed or taken out of forest production as a result of the project should be listed.. Efforts
should be made to align corridors to minimize impacts to woodlands in the following order of priority:
• Managed, high site index woodland
• Productive forested woodlands .
• Managed, lower site index woodlands
• Unique forest ecosystems
• Unmanaged, fully stocked woodlands.
• Unmanaged, cutover woodlands
• Urban woodlands
2. The productivity of the forest soils affected by the proposed project as indicated by the soil series.
3. The provisions the contractor will take to utilize the merchantable timber removed during construction.
Emphasis should be on selling all wood products. However, if the wood products cannot be sold then
efforts should be made to haul off the material or tum it into mulch with a tub grinder. This practice will
minimize the need for debris burning, and the risk of escaped fires and smoke management problems to
residences, highways, schools, and towns.
4. If debris burning is needed, the contractor must comply with the laws and regulations of open burning as
covered under G.S. 113-60.21 through G.S. 113-60.3 i. Caldwell County is a non-high hazard county,
and G.S. 113-60.24 requiring a regular burning permit would apply.
5. The provisions that the contractor will take to prevent erosion and damage to forestland outside the
right-of-way. Trees, particularly the root system, can be permanently damaged by heavy equipment.
Efforts should be to avoid skinning of the tree trunk, compacting the soil, adding layers of fill, exposing
the root system, or spilling petroleum or other substances.
6. The impact upon any existing greenways in the proposed project area.
We appreciate the opportunity to comment on the proposed project, and encourage the impact on forest
resources be considered during the planning process.

consulted, the person delineating wetlands should be identified and criteria listed.
' 4) Description of project activities that will occur within wetlands and stream channel .
alterations. Acreages of wetlands impacted and linear feet of stream channels to be
relocated, channelized or culverted by each alternative designs should be listed. Project
' sponsors should indicate whether the Corps has been contacted to determine the need for
a 404 Permit under the Clean Water Act.
5) Description of project site and non-wetland vegetative communities.
6) The extent to which the project will result in loss, degradation, or fragmentation of
' wildlife habitat.
7) Any measures proposed to avoid or reduce impacts of the project or to mitigate for
' unavoidable habitat losses. A mitigation plan should be prepared and submitted along

We have received information concerning the above project from the State
Clearinghouse. .
We have conducted a search of our files and are aware of no structures of
' historical or architectural importance located within the planning area.
While we note that this project is to be state funded, the potential for federal
f permits may require further consultation and compliance with Section 106 of the '
National Historic Preservation Act.
There are no known recorded archaeological sites within the project boundaries.
However, the project area has never been systematically surveyed to determine the
location or significance of archaeological resources.. We recommend that a ?!
comprehensive survey be conducted by an experienced archaeologist to identify the
presence and significance of archaeological remains that may be damaged of -
destroyed by the proposed project. Potential effects on unknown resources should
' be assessed prior to the initiation of construction activities.
These comments are made in accord with G.S. 121-12(a) and Executive Order XVI.
If you have any questions regarding them, please contact Renee Gledhill-Earley,
environmental review coordinator, at 9191733-4763.

Dear Mr. Davis:
May 2, 2000
On May 1, 2000, I conducted a field survey on the proposed McLean Drive extension to identify
the species of heartleaf that are growing within the alignment. Two species were present as was
identified in the initial investigation. The species growing on the slopes and in drier areas is
Hexastylis arifolia. The species growing along the banks of Stream 3 at the bottom of the ravine
is Hexastylis shuttleworthii. No specimens of dwarf-flowered heartleaf, Hexastylis naniflora,
were found.
If there are any questions or you need further assistance with this matter, please call me at (828)-
497-6506.
Sincerely,

Pamela M. Boaze
President

' McLean Drive Extension
Dwarf-flowered heartleaf Survey
' Fish and Wildlife Associates, Inc. conducted a field survey for dwarf-flowered heartleaf on May 1,
2000. During the initial biological investigation of the proposed McLean Drive Extension, two
species of heartleaf were found. Final identification of these plants could not be made until the
flowers were present. This survey was conducted to make a positive identification of the heartleaf
species found in the ravine at stream 3.
' Twelve specimens were located, of which two had flowers. The specimens were identified as
Hexastylis shuttleworthii. A second species of heartleaf, Hexastylis arifolia, was also found in
' the area. No other species of heartleaf were found.

Both through and turning traffic will move efficiently along the roadway. Disadvantages of
the Build Alternative consist of short-term inconvenience during construction of the
proposed intersections with US 321 and Hibriten Drive (SR 1178) due to the presence of
construction equipment adjacent to the existing roadways. The proposed project will
displace one residential structure. No other resident or business will be displaced. The
benefits of the extension of McLean Drive (SR 1180) include improving traffic safety and
providing convenient access for future residential and commercial development, and
allowing the development of vacant land which in turn will add 'to the tax base for the City
of Lenoir.
Alternate alignments for the extension were considered during planning and functional
design. The potential alignments primarily considered the topography of the land.
To determine the preferred alignment, the following objectives were addressed:
• Provide at-grade intersection at US 321 and SR 1178 (Hibriten Drive)
• Provide smooth transition to the existing roadway at SR 1178 (Hibriten Drive)
• Direct Hibriten Drive traffic to the McLean Drive extension by making McLean
Drive and Hibriten Drive a continuous roadway.
• Provide at-grade perpendicular connections for the proposed residential and
commercial development
• Balance earthwork by minimizing cuts and fills
• Minimize impacts to the natural environment, including one forested wetland and
crossing of existing streams.
The most practicable alignment was developed into functional design plans. The alignment
shown was determined to be the only practicable design to meet the project's objectives.

5. Social, Economic, and Environmental Impacts
Social and Economic
Executive Order 12898 (Federal Actions to Address Environmental Justice in Minority
Populations and Low Income Populations) requires a review of census data to determine
whether any minority or low-income populations will receive disproportionately high and
adverse human, health or environmental impacts as a result of this project. No minority or
low-income populations will be affected by direct or indirect impacts of the proposed
project, since the land over which the roadway is to be constructed is vacant woodland.
The proposed extension of McLean Drive (SR 1180) will not cut off any neighborhoods or
local streets. The improvements will be integrated into the current and proposed
transportation network. Access will not be controlled along the roadway except through
the commercial area. There are no established communities within the project area that
would be affected by the proposed extension. The proposed project will displace one
residential structure. No other resident or business will be displaced.
The existing land use in the area of the proposed McLean Drive Extension (SR 1180) is
undeveloped forested land. The undeveloped land adjacent the proposed McLean Drive
Extension is planned for residential development. The residential development will consist
of 300 single-family home sites. Commercial development at the intersection of US 321 is
under construction. Commercial development is planned at the intersection of US 321 that
includes 300,000 square feet of commercial retail space.
Approximately nineteen (19) acres of existing woodlands will be cleared for the right-of-
way for the proposed Extension. The turning lanes added along US 321 will impact only
existing grassed or concrete median or shoulders. A portion of the existing Hibriten Drive
(SR 1173) will be reconfigured to intersect the proposed roadway.
4
The McLean Drive Extension (SR 1180) will be used primarily by residents of the future
residential development and by shoppers to the commercial development. Improving
access will have a positive impact on the local economy. Commuters to the new
commercial development will have access to the area from a roadway other than US 321.
Users of the proposed roadway will benefit from reduced travel time and reduced
congestion.
Environmental
Traffic noise results from the vehicle's engine, exhaust, and drive train, and from the tire-
roadway interaction. The actual magnitude of sound is caused by short-duration
fluctuations in atmospheric pressure. Based on the predicted noise contours, the noise
impact is expected to be minimal. The 66 dBA noise contour line ranges from within the
right-of-way to 62 feet from the centerline. The worst-case noise prediction, in 2025, for
the 66 dBA level is 12 feet outside the right-of-way, which is considerably closer than local
property setback regulations would allow a building or structure. Based on the analysis,
the proposed project will not impact any existing or proposed residential receptors. No
abatement measures are proposed.
Although high equipment noise levels are expected to be the main contributor to the
construction activity noise emission, noise impacts during construction are of short
duration. Peak noise levels from highway construction equipment measured at a distance
of 50 feet away may vary from 70 to 100 dBA. The major source of noise will be from
earth removal, handling, grading, pile driving, and paving. General construction noise
impacts that can be expected are temporary speech interference for passersby and those
individuals working on or near the project. Such noise will be limited to day light hours as
much as possible.
5
Based on literature reviews, aerial photograph interpretation, and field reconnaissance, the
existing natural environmental and potential impacts of the project were assessed.
A total of four (4) streams were identified during the field survey and within the project
limits. Three (3) of streams are shown as blue line streams on the United States Geologic
Survey map. Since the approval of the State Environmental Assessment, the McLean
Drive Extension project has been split into two projects. The portion of the project from
US 321 to Station 15 +00 is approved for construction as a driveway permit through the
NCDOT Division office. This portion is under construction by a private developer, but
will be added to the State's Highway System upon completion of the remaining portion of
McLean Drive Extension.
The private developer applied for and was granted a 401 Water Quality Certification for
480 L.F. of stream mitigation on January 8, 1999 (DWQ Project #980726) for two of the
three streams impacted. Payment in the amount of $60,000 was paid to the Wetlands.
Restoration Program on January 8, 1999. Mitigation for the impacted stream (280 L.F.)
by this project will be from a mitigation plan or on a compensatory basis.
The US Fish and Wildlife Service, the North Carolina Natural Heritage Program, and the
North Carolina Wildlife Resources Commission were contacted to obtain current listings of
and concerns about threatened and endangered species. None of the species listed were
identified in the proposed project area.
Positive impacts from the road corridor will include an increase in forest edge, thereby
creating more feeding habitat for prey and predator species. Negative impacts include
bisection of the wooded area, thus creating a likelihood of road kills. There will be a loss
of habitat for both aquatic species and terrestrial species to the extent that ravines are filled
6
and the area is covered by roadway. Approximately nineteen (19) acres of habitat will be
lost to roadway.
No adverse impacts will occur to air quality, long-term water quality, cultural resources,
federally protected species, hazardous material sites, or known underground storage tanks.
6. Wetlands Finding
Wetlands are defined by the U.S. Army Corps of Engineers (COE) (33CFR 328.3) and the
U.S. Environmental Protection Agency (EPA) (40 CFR 230.0) as:
"those areas that are inundated or saturated by surface or ground water at a frequency
and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs, and similar areas."
The Jurisdictional Surface Waters are shown on Figure 4-2. Upon investigation, there are
no wetland resources within the project area indicated on the National Wetlands Inventory
Map
The field survey for this project was completed in September 1998. During the survey,
areas of wetlands were identified within the banks of Stream 3 and one adjacent wetland
area fed by seepage that would be impacted by the road construction. These impacted
wetlands are shown on Figure 4-2. The predominant vegetation in the impacted area was
sweet gum, laurel, and sawbrier. Other woody vegetation such as sycamore, red maple,
and yellow poplar were present. Mutliflora rose and spice bush were present in the
understory, but very little herbaceous layer was present.

Within the banks of Stream 3, small islands, sand bars, and mud flats are exposed and have
herbaceous vegetation growing on them. Various grasses, sedges, jewel weed, and smart
weed were the predominant vegetation. The total area of wetlands within Stream 3 that
will be impacted by the road construction will be approximately 0.02 acre.
An additional small wetland area, 0.03 acre, adjacent to Stream 3, was located outside of
the road right-of-way, but within the proposed slope fill. It appears to be fed by a seep.
There was standing water present and soil was saturated. Predominant vegetation was
smart weed. Other species normally associated with wetland areas that were observed
include willow and arrowhead. The soil map showed the presence of a small area of
Chewacla loam that has hydric inclusions of Wehadkee loam. The classification for his
area according to the US FWS (Corwardin 1979) is PEM1B.
The total wetlands impacted by the project are 0.05 acres. Mitigation is not required for
wetland impacts less than one-tenth of an acre. Therefore, no wetland mitigation will be
required for the project construction. A final determination regarding mitigation
requirements rests with the United States Corps of Engineers and the North Carolina
Department of Environment and Natural Resource, Division of Water Quality.
7. Floodplain Finding
Floodplain areas are addressed by both federal and state regulations. The objectives of
Executive Order 11988, Floodplain Management, and NCDOT Order 5650.2, Floodplain
Management and Protection, are to avoid adverse impacts due to occupancy and alteration
of the 100-year floodplain unless that location is the only practicable alternative. When
floodplain areas are impacted, every effort must be made to minimize the potential risks to
human safety and to property and to minimize negative effects on natural and beneficial
8
floodplains. There are no designated 100-year floodplains in the area of the McLean Drive
(SR 1180) Extension.
8. Circulation of Environmental Assessment
The Environmental Assessment (EA) was approved by NCDOT on August 10, 2000. The
approved EA with a scoping letter, identifying the project and requesting comments, was
distributed to the following agencies:
U.S. Army Corps of Engineers
U. S. Fish and Wildlife Service
U. S. Environmental Protection Agency
N. C. Department of Cultural Resources
N.C. Department of Public Instruction
N. C. Department of Environment, and Natural Resources
N.C. Wildlife Resources Commission
City of Lenoir
9. Comments from Agencies
Written comments regarding the Environmental Assessment were received from two (2)
agencies. Copies of these letters are included in the Appendix. The following is a
summary of these comment letters with responses.
North Carolina Department of Environment and Natural Resources Division of Water
Quality (DWQ) - dated November 14, 2000
9
Comment:
Appropriate mitigation plans will be required prior to issuance of a 401 Water Quality
Certification. Wetland and stream impacts should be avoided to the maximum extent
practical.
Response:
The City of Lenoir is currently working on a mitigation plan for the Lower Creek drainage
basin. The plan will be submitted to DWQ for approval for a Section 401 Water Quality
Certification. In addition, a Section 404 Permit will be required from the U.S. Army
Corps of Engineers for the discharge of dredged or fill materials into waters of the United
States.
North Carolina Wildlife Resources Commission - dated November 21, 2000
Comment:
No objection to the project. NCDOT should look for ways to minimize impacts to the
streams through the use of Best Management Practices.
Response:
The final design will incorporate the required use of Best Management Practices in contract
documents.

10. Comments from Public
On February 15, 2001, the Citizens Informational Workshop was held for McLean Drive
Extension (TIP No. U-3813) from 4:30 p.m. to 6:30 p.m. at the City / County Chambers,
Caldwell County Administrative Offices. Approximately 40 concerned citizens and 11
public officials (including officials from NCDOT, City of Lenoir and Caldwell County)
attended the public meeting.
The following comments were either received during the workshop or following the
meeting in writing.
1. COMMENT:
What will be the traffic impact on Hibriten Drive?
RESPONSE:
A traffic analysis completed by NCDOT in 1998 indicates that there will be only a minimal
increase in traffic along S.R. 1178 (Hibriten Drive) as a result of the construction of TIP
No. U-3813 (McLean Drive Extension).
2. COMMENT:
What improvements will be made to Hibriten Drive as a result of the new road?
RESPONSE:
There will be no improvements to Hibriten Drive as part of this project. Hibriten Drive
will be re-routed at the intersection with TIP No. U-3813 (McLean Drive Extension) to
accommodate the new road.
3. COMMENT:
What steps will be taken to address the existing truck traffic on Hibriten Drive?
RESPONSE:
TIP No. U-3813 project does not address the existing truck traffic on Hibriten Drive.
Hibriten Drive is already posted with "No Trucks" signs. NCDOT and local enforcement
agencies will continue to monitor the use of Hibriten Drive by trucks.
4. COMMENT:
What measures will be taken to deter traffic from using McLean Drive Extension and
Hibriten Drive as a cut through to avoid the intersection at U.S. 321 and U.S. 64?
RESPONSE:
McLean Drive Extension will begin as a 4-lane divided roadway, with curb and gutter, at
U.S. 321 and continue for approximately 1500 feet before tapering to a two-lane roadway
with grass shoulders. The posted speed limit will be 35 miles per hour. Since the
extension merges into Hibriten Drive there would not be an incentive for traffic to use the
extension as a cut through. The physical construction and layout will provide a deterrent
for cut through traffic.
5. COMMENT:
What effect will the construction of McLean Drive Extension have on water quality of
Lower Creek?
RESPONSE:
The construction drawings, including erosion control measures, will be approved by
NCDOT prior to construction. The Contractor will be required to construct the road in
accordance with the approved plans; therefore, the water quality impacts should be
12
minimal. Any impacts to upland streams will require permitting by regulatory agencies
prior to final approval of the project.
6. COMMENT:
What will be run-off impacts to Lower Creek from the construction of McLean Drive
Extension?
RESPONSE:
The run-off from TIP No. U-3813 (McLean Drive Extension) will be channeled into three
(3) existing natural drainage ways. These drainage ways then drain to Lower Creek.
There will be increased run-off into Lower Creek, but the proposed road is approximately
2,000 feet away from Lower Creek, allowing natural drainage ways to lessen the impact on
Lower Creek. As stated in comment #5, the construction drawings, including erosion
control measures, will be approved by NCDOT prior to construction. The Contractor will
be required to construct the road in accordance with the approved plans.
7. COMMENT:
Does NCDOT have any plans to address safety issues at the intersection of Hibriten Drive
and U.S. 64?
RESPONSE:
During discussions with NCDOT following the meeting, NCDOT stated the improvements
to the intersection of Hibriten Drive and U.S. 64 are on the list of improvements. As of
the week of August 27, 2001 a traffic signal has been installed and should be in operation
by September 7, 2001.
13
8. COMMENT:
Why are NCDOT, City of Lenoir, and Caldwell County helping to fund this project when
a private developer will benefit the most?
RESPONSE:
The McLean Drive Extension is an implementation of the State's Transportation
Improvement Program (TIP) and the Caldwell County's Transportation Plan and is
compatible with the City of Lenoir's Land Use and Transportation Plan for the area. The
extension will provide safe access to 300 proposed residential homes and more than
300,000 square feet of retail space. The extension will also provide an overall effective
benefit by reducing congestion at the surrounding intersections.
9. COMMENT:
What will be the impact on existing McLean Drive?
RESPONSE:
A traffic analysis completed by NCDOT in 1998 indicates that there will be only a minimal
increase in traffic along S.R. 1180 (existing McLean Drive) as a result of the construction
of TIP No. U-3813 (McLean Drive Extension).
10. COMMENT:
Why is McLean Drive Extension classified as a minor thoroughfare?
RESPONSE:
In a memo dated May 13, 1998, the Statewide Planning Branch classified the McLean
Drive Extension as a minor thoroughfare because it will serve primarily local traffic. With
the current project termini, the extension will not function as a major radial facility or a
major loop facility.
14
11. COMMENT:
Are there any impacts to existing properties or structures from the construction of McLean
Drive Extension?
RESPONSE:
There are ten (10) individual property owners which will be impacted by the construction
of TIP No. U-3813.
At this time none of the easements / right of ways have been obtained. The City of Lenoir
will be contacting the impacted property owners to discuss these issues.
12. COMMENT:
Why were the citizens not informed about the project until now?
RESPONSE:
The process for developing a project like this is very long. The planning documents have
to be completed in order to have appropriate information to provide to the public. This
project has been discussed on several occasions at the City of Lenoir Council meetings and
the Caldwell County Commissioner's meetings. The purpose of the Citizens Informational
Workshop on February 15, 2001 was to present the detailed plans to the public as required
by NCDOT.
13. COMMENT:
Please install traffic signals at the intersections of SR 1180 (McLean Drive Extension) and
SR 1178 (Hibriten Drive) and SR 1178 and U.S. 64.
15
RESPONSE:
At this time, there are no plans to install a traffic signal at the intersection of TIP No. U-
3813 (McLean Drive Extension) and Hibriten Drive. As with all intersections, NCDOT
will continue to evaluate the operation of the intersection.
During discussions with NCDOT following the meeting, NCDOT stated the improvements
to the intersection of SR 1178 (Hibriten Drive) and U.S. 64 are on the list of
improvements. As of the week of August 27, 2001 a traffic signal has been installed and
should be in operation by September 7, 2001.
14. COMMENT:
How will the intersection at McLean Drive Extension and Hibriten Drive impact traffic
flow for current users of Hibriten? (i.e. new left and right turns for straight thru traffic on
Hibriten)
RESPONSE:
TIP No. U-3813 (McLean Drive Extension) / Hibriten intersection will function as a "T"
intersection. The traffic heading south bound on Hibriten Drive can either continue
straight on McLean Drive Extension or utilize a left turn lane and turn left to continue on
existing Hibriten Drive. The traffic heading north bound on Hibriten Drive will have to
stop and turn right to continue on Hibriten Drive or turn left to get on TIP No. U-3813
(McLean Drive Extension).
15. COMMENT:
Will there be a new traffic signal installed at McLean Drive Extension and Hibriten Drive?
16
RESPONSE:
At this time, there are no plans to install a traffic signal at the intersection of TIP No. U-
3813 (McLean Drive Extension) and Hibriten Drive. As with all intersections, NCDOT
will continue to evaluate the operation of the intersection.
11. Revisions to the Environmental Assessment
Since the approval of the State Environmental Assessment, the McLean Drive Extension
project has been split into two projects. The portion of the project from US 321 to Station
15 +00 is approved for construction as a driveway permit through the Division office. This
portion is under construction by a private developer, but will be turned over to NCDOT
upon completion of the remaining portion of McLean Drive Extension.
The proposed project will displace one residential structure. Prior to final approval, the
City of Lenoir must secure an easement or ownership of property.
The approved Environmental Assessment identified four (4) streams within the project
limits. Upon further investigation only three (3) are flowing streams as identified on the
USGS map. The portion of the McLean Drive Extension from Station 15 +00 to Hibriten
Drive includes one stream crossing. This portion of the roadway construction will impact
280 L.F. of stream. The mitigation for the impacted stream will be from a mitigation plan
or on a compensatory basis.
A private developer is constructing the portion of McLean Drive Extension from US 321 to
Station 15+00. The private developer applied for and was granted a 401 Water Quality
Certification for 480 L.F. of stream mitigation on January 8, 1999 (DWQ Project
#980726) for two of the three streams impacted. Payment in the amount of $60,000 was
paid to the Wetlands Restoration Program on January 8, 1999.
17
12. Basis for Finding of No Significant Impact
Based upon a study of the proposed project as documented in the Environmental
Assessment, and upon comments received from Federal, State and Local agencies, it is the
finding of the North Carolina Department of Transportation that the project will not have
significant impact upon the human or natural environment. The project is consistent with
plans and goals that have been adopted by the appropriate local governments and the State
of North Carolina. Therefore, an environmental impact statement will not be required.

From: Cynthia F. Van Der Wiele CA,&J
Subject: Comments for SR 1180 (McLean Drive) Extension, from US 321 to SR 1178
(Hibriten Drive) in Caldwell County, State Project No. 9.8111589, TIP Project
No. U-3813.
This letter is in reference to your request for comments dated October-30, 2000. Preliminary
analysis of the project reveals that the proposed project will impact six streams in the Catawba .
Rives- Basin; the recommended alternative will have some wetland impacts.
The Division of Water Quality requests that NCDOT consider the following environmental
issues for the proposed project:
A. NCDOT should anticipate the potential for 50' stream buffers in the Catawba River Basin
and plan the roadway design accordingly.
B. There should be a discussion on mitigation plans for unavoidable impacts. If mitigation is
required, it is preferable to present a conceptual (if not finalized) mitigation plan with the
environmental documentation.. While the NCDWQ realizes that this may not always be
practical, it should be noted that for projects requiring mitigation, appropriate mitigation
plans will be required prior to issuance of a 401 Water Quality Certification.
C. DWQ prefers replacement of bridges with bridges. DOT should not install the bridge bents
in the creek, to the maximum extent practicable. If the new structure is to be a culvert, it
should be countersunk one foot, or to the maximum extent practicable, in order to allow
unimpeded fish and other aquatic organisms passage through the crossing.
D. When practical, the DWQ requests that bridges be replaced on the existing location with
road closure. If a detour proves necessary, remediation measures in accordance with the
NCDWQ requirements for General 401 Certification 2726/Nationwide Permit No. 33
(Temporary Construction, Access and Dewatering) must be followed.
E. Wetland and stream impacts should be avoided (including sediment and erosion control
structures/measures) to the maximum extent practical. If this is not possible, alternatives
that minimize wetland impacts should be chosen.

Staff biologists with the N. C. Wildlife Resources Commission have reviowed the subject EA and
are familiar with habitat values in the project area. The purpose of this review was to assess project
impacts to fish and wildlife resources. Our comments are provided in accordance with certain provisions
of the North Carolina Environmental Policy Act (G.S. 113A-1 et seq., as amended; 1 NCAC 25).
NCDOT proposes to extend SR 1180 from US 321 to SR 1178. The total project length is
approximately 0.98 miles. Impacts to wetlands arc expected to total approximately 0.05 acres with 1,788
linear feet of stream impacts expected.
We have reviewed the data coniained in tho EA. We do not object to the project as proposed.
NCDOT should lm)k for ways to minimize impacts to streams. Best Management Practices for the
protection of Stirfhee Waters should be strictly f4llgwed. At this time, we concur with the EA for this
project.
Thank you for the opportunity to comment on this EA. If we can be of any further assistance please

1. Type of Action
This is a North Carolina Department of Transportation (NCDOT) Administrative Action,
State Finding of No Significant Impact (SFONSI).
The NCDOT has determined that this project will not have any significant impact on the
human or natural environment. The Finding of No Significant Impact is based on the
Environmental Assessment, which has been independently evaluated and determined to
adequately and accurately discuss the environmental issues and impacts of the proposed
project. Copies of the Environmental Assessment are on file at the Project Development
and Environmental Analysis Branch of the NCDOT. The Environmental Assessment
provides sufficient evidence and analysis for determining that an Environmental Statement
is not required.

3. Description of the Proposed Project
The City of Lenoir is proposing to extend McLean Drive (SR 1180) from its current
intersection with US 321 to the intersection of Hibriten Drive (SR 1178) and Haigler Road
1
(SR 1711) (see Figure 1-1). McLean Drive Extension is a proposed minor thoroughfare
extension that will serve local traffic and provide access for future development. The
Extension will begin as a divided four-lane roadway with curbs-and-gutters at US 321 and
continue for approximately 1500 feet before tapering to a two-lane roadway with grass
shoulders. The project is approximately 0.98 mile in length. The project is included in the
2002-2008 NCDOT Transportation Improvement Program (TIP) as TIP Project No. U-
3813. Construction is scheduled to begin in Fiscal Year 2002. The estimated construction
cost of the project from Station 15 +00 to the Hibriten Drive is $2.47 million.
Since the approval of the State Environmental Assessment, the McLean Drive Extension
project has been split into two projects. The portion of the project from US 321 to Station
15+00 is approved for construction as a driveway permit through the NCDOT Division
office. This portion is under construction by a private developer, but will be turned over to
NCDOT upon completion of the remaining portion of McLean Drive Extension.
4. Recommended Alternative
The Recommended Alternative is the proposed extension of McLean Drive (SR 1180) from
US 321 to Hibriten Drive (SR 1178). The McLean Drive Extension is a four-lane divided
roadway with turning lanes for access to the commercial shopping area and at the US 321
intersection. The divided roadway will continue for approximately 1500 feet and then
taper to a two-lane roadway extending northeasterly from the end of the four-lane section
to its intersection with SR 1178 (Hibriten Drive). The Extension will merge into the two-
lane Hibriten Drive (SR 1178) at the northern project terminus and will continue north as
Hibriten Drive.
The completed project will provide an adequate level-of-service for local area citizens
through the year 2025 for planned residential and commercial development in the area.

Both through and turning traffic will move efficiently along the roadway. Disadvantages of
the Build Alternative consist of short-term inconvenience during construction of the
proposed intersections with US 321 and Hibriten Drive (SR 1178) due to the presence of
construction equipment adjacent to the existing roadways. The proposed project will
displace one residential structure. No other resident or business will be displaced. The
benefits of the extension of McLean Drive (SR 1180) include improving traffic safety and
providing convenient access for future residential and commercial development, and
allowing the development of vacant land which in turn will add to the tax base for the City
of Lenoir.
Alternate alignments for the extension were considered during planning and functional
design. The potential alignments primarily considered the topography of the land.
To determine the preferred alignment, the following objectives were addressed:
• Provide at-grade intersection at US 321 and SR 1178 (Hibriten Drive)
• Provide smooth transition to the existing roadway at SR 1178 (Hibriten Drive)
• Direct Hibriten Drive traffic to the McLean Drive extension by making McLean
Drive and Hibriten Drive a continuous roadway.
• Provide at-grade perpendicular connections for the proposed residential and
commercial development
• Balance earthwork by minimizing cuts and fills
• Minimize impacts to the natural environment, including one forested wetland and
crossing of existing streams.
The most practicable alignment was developed into functional design plans. The alignment
shown was determined to be the only practicable design to meet the project's objectives.

5. Social, Economic, and Environmental Impacts
Social and Economic
Executive Order 12898 (Federal Actions to Address Environmental Justice in Minority
Populations and Low Income Populations) requires a review of census data to determine
whether any minority or low-income populations will receive disproportionately high and
adverse human, health or environmental impacts as a result of this project. No minority or
low-income populations will be affected by direct or indirect impacts of the proposed
project, since the land over which the roadway is to be constructed is vacant woodland.
The proposed extension of McLean Drive (SR 1180) will not cut off any neighborhoods or
local streets. The improvements will be integrated into the current and proposed
transportation network. Access will not be controlled along the roadway except through
the commercial area. There are no established communities within the project area that
would be affected by the proposed extension. The proposed project will displace one
residential structure. No other resident or business will be displaced.
The existing land use in the area of the proposed McLean Drive Extension (SR 1180) is
undeveloped forested land. The undeveloped land adjacent the proposed McLean Drive
Extension is planned for residential development. The residential development will consist
of 300 single-family home sites. Commercial development at the intersection of US 321 is
under construction. Commercial development is planned at the intersection of US 321 that
includes 300,000 square feet of commercial retail space.
Approximately nineteen (19) acres of existing woodlands will be cleared for the right-of-
way for the proposed Extension. The turning lanes added along US 321 will impact only
existing grassed or concrete median or shoulders. A portion of the existing Hibriten Drive
(SR 1173) will be reconfigured to intersect the proposed roadway.
4
The McLean Drive Extension (SR 1180) will be used primarily by residents of the future
residential development and by shoppers to the commercial development. Improving
access will have a positive impact on the local economy. Commuters to the new
commercial development will have access to the area from a roadway other than US 321.
Users of the proposed roadway will benefit from reduced travel time and reduced
congestion..
Environmental
Traffic noise results from the vehicle's engine, exhaust, and drive train, and from the tire-
roadway interaction. The actual magnitude of sound is caused by short-duration
fluctuations in atmospheric pressure. Based on the predicted noise contours, the noise
impact is expected to be minimal. The 66 dBA noise contour line ranges from within the
right-of-way to 62 feet from the centerline. The worst-case noise prediction, in 2025, for
the 66 dBA level is 12 feet outside the right-of-way, which is considerably closer than local
property setback regulations would allow a building or structure. Based on the analysis,
the proposed project will not impact any existing or proposed residential receptors. No
abatement measures are proposed.
Although high equipment noise levels are expected to be the main contributor to the
construction activity noise emission, noise impacts during construction are of short
duration. Peak noise levels from highway construction equipment measured at a distance
of 50 feet away may vary from 70 to 100 dBA. The major source of noise will be from
earth removal, handling, grading, pile driving, and paving. General construction noise
impacts that can be expected are temporary speech interference for passersby and those
individuals working on or near the project. Such noise will be limited to day light hours as
much as possible.
5
Based on literature reviews, aerial photograph interpretation, and field reconnaissance, the
existing natural environmental and potential impacts of the project were assessed.
A total of four (4) streams were identified during the field survey and within the project
limits. Three (3) of streams are shown as blue line streams on the United States Geologic
Survey map. Since the approval of the State Environmental Assessment, the McLean
Drive Extension project has been split into two projects. The portion of the project from
US 321 to Station 15+00 is approved for construction as a driveway permit through the
NCDOT Division office. This portion is under construction by a private developer, but
will be added to the State's Highway System upon completion of the remaining portion of
McLean Drive Extension.
The private developer applied for and was granted a 401 Water Quality Certification' for
480 L.F. of stream mitigation on January 8, 1999 (DWQ Project #980726) for two of the
three streams impacted. Payment in the amount of $60,000 was paid to the Wetlands
Restoration Program on January 8, 1999. Mitigation for the impacted stream (280 L.F.)
by this project will be from a mitigation plan or on a compensatory basis.
The US Fish and Wildlife Service, the North Carolina Natural Heritage Program, and the
North Carolina Wildlife Resources Commission were contacted to obtain current listings of
and concerns about threatened and endangered species. None of the species listed were
identified in the proposed project area.
Positive impacts from the road corridor will include an increase in forest edge, thereby
creating more feeding habitat for prey and predator species. Negative impacts include
bisection of the wooded area, thus creating a likelihood of road kills. There will be a loss
of habitat for both aquatic species and terrestrial species to the extent that ravines are filled
6
and the area is covered by roadway. Approximately nineteen (19) acres of habitat will be
lost to roadway.
No adverse impacts will occur to air quality, long-term water quality, cultural resources,
federally protected species, hazardous material sites, or known underground storage tanks.
6. Wetlands Finding
Wetlands are defined by the U.S. Army Corps of Engineers (COE) (33CFR 328.3) and the
U.S. Environmental Protection Agency (EPA) (40 CFR 230.0) as:
"those areas that are inundated or saturated by surface or ground water at a frequency
and duration sufficient to support, and that under normal circumstances do support, a
prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands
generally include swamps, marshes, bogs, and similar areas."
there are
The Jurisdictional Surface Waters are shown on Figure 4-2. Upon investigation,
no wetland resources within the project area indicated on the National Wetlands Inventory
Map.
The field survey for this project was completed in September 1998. During the survey,
areas of wetlands were identified within the banks of Stream 3 and one adjacent wetland
area fed by seepage that would be impacted by the road construction. These impacted
wetlands are shown on Figure 4-2. The predominant vegetation in the impacted area was
sweet gum, laurel, and sawbrier. Other woody vegetation such as sycamore, red maple,
and yellow poplar were present. Mutliflora rose and spice bush were present in the
understory, but very little herbaceous layer was present.

Within the banks of Stream 3, small islands, sand bars, and mud flats are exposed and have
herbaceous vegetation growing on them. Various grasses, sedges, jewel weed, and smart
weed were the predominant vegetation. The total area of wetlands within Stream 3 that
will be impacted by the road construction will be approximately 0.02 acre.
An additional small wetland area, 0.03 acre, adjacent to Stream 3, was located outside of
the road right-of-way, but within the proposed slope fill. It appears to be fed by a seep.
There was standing water present and soil was saturated. Predominant vegetation was
smart weed. Other species normally associated with wetland areas that were observed
include willow and arrowhead. The soil map showed the presence of a small area of
Chewacla loam that has hydric inclusions of Wehadkee loam. The classification for his
area according to the US FWS (Corwardin 1979) is PEM113.
The total wetlands impacted by the project are 0.05 acres. Mitigation is not required for
wetland impacts less than one-tenth of an acre. Therefore, no wetland mitigation will be
required for the project construction. A final determination regarding mitigation
requirements rests with the United States Corps of Engineers and the North Carolina
Department of Environment and Natural Resource, Division of Water Quality.
7. Floodplain Finding
Floodplain areas are addressed by both federal and state regulations. The objectives of
Executive Order 11988, Floodplain Management, and NCDOT Order 5650.2, Floodplain
Management and Protection, are to avoid adverse impacts due to occupancy and alteration
of the 100-year floodplain unless that location is the only practicable alternative. When
floodplain areas are impacted, every effort must be made to minimize the potential risks to
human safety and to property and to minimize negative effects on natural and beneficial
8
floodplains. There are no designated 100-year floodplains in the area of the McLean Drive
(SR 1180) Extension.
8. Circulation of Environmental Assessment
The Environmental Assessment (EA) was approved by NCDOT on August 10, 2000. The
approved EA with a scoping letter, identifying the project and requesting comments, was
distributed to the following agencies:
U.S. Army Corps of Engineers
U.S. Fish and Wildlife Service
U.S. Environmental Protection Agency
N.C. Department of Cultural Resources

N.C. Department of Environment, and Natural Resources
N.C. Wildlife Resources Commission
City of Lenoir
9. Comments from Agencies
Written comments regarding the Environmental Assessment were received from two (2)
agencies. Copies of these letters are included in the Appendix. The following is a
summary of these comment letters with responses.
North Carolina Department of Environment and Natural Resources - Division of Water
Quality (DWQ) - dated November 14, 2000
9
Comment:
Appropriate mitigation plans will be required prior to issuance of a 401 Water Quality
Certification. Wetland and stream impacts should be avoided to the maximum extent
practical.
Response:
The City of Lenoir is currently working on a mitigation plan for the Lower Creek drainage
basin. The plan will be submitted to DWQ for approval for a Section 401 Water Quality
Certification. In addition, a Section 404 Permit will be required from the U.S. Army
Corps of Engineers for the discharge of dredged or fill materials into waters of the United
States.
North Carolina Wildlife Resources Commission - dated November 21, 2000
Comment:
No objection to the project. NCDOT should look for ways to minimize impacts to the
streams through the use of Best Management Practices.
Response:
The final design will incorporate the required use of Best Management Practices in contract
documents.

10. Comments from Public
On February 15, 2001, the Citizens Informational Workshop was held for McLean Drive
Extension (TIP No. U-3813) from 4:30 p.m. to 6:30 p.m. at the City / County Chambers,
Caldwell County Administrative Offices. Approximately 40 concerned citizens and 11
public officials (including officials from NCDOT, City of Lenoir and Caldwell County)
attended the public meeting.
The following comments were either received during the workshop or following the
meeting in writing.
1. COMMENT:
What will be the traffic impact on Hibriten Drive?
RESPONSE:
A traffic analysis completed by NCDOT in 1998 indicates that there will be only a minimal
increase in traffic along S.R. 1178 (Hibriten Drive) as a result of the construction of TIP
No. U-3813 (McLean Drive Extension).
2. COMMENT:
What improvements will be made to Hibriten Drive as a result of the new road?
RESPONSE:
There will be no improvements to Hibriten Drive as part of this project. Hibriten Drive
will be re-routed at the intersection with TIP No. U-3813 (McLean Drive Extension) to
accommodate the new road.
11
3. COMMENT:
What steps will be taken to address the existing truck traffic on Hibriten Drive?
RESPONSE:
TIP No. U-3813 project does not address the existing truck traffic on Hibriten Drive.
Hibriten Drive is already posted with "No Trucks" signs. NCDOT and local enforcement
agencies will continue to monitor the use of Hibriten Drive by trucks.
4. COMMENT:
What measures will be taken to deter traffic from using McLean Drive Extension and
Hibriten Drive as a cut through to avoid the intersection at U.S. 321 and U.S. 64?
RESPONSE:
McLean Drive Extension will begin as a 4-lane divided roadway, with curb and gutter, at
U.S. 321 and continue for approximately 1500 feet before tapering to a two-lane roadway
with grass shoulders. The posted speed limit will be 35 miles per hour. Since the
extension merges into Hibriten Drive there would not be an incentive for traffic to use the
extension as a cut through. The physical construction and layout will provide a deterrent
for cut through traffic.
5. COMMENT:
What effect will the construction of McLean Drive Extension have on water quality of
Lower Creek?
RESPONSE:
The construction drawings, including erosion control measures, will be approved by
NCDOT prior to construction. The Contractor will be required to construct the road in
accordance with the approved plans; therefore, the water quality impacts should be
12
minimal. Any impacts to upland streams will require permitting by regulatory agencies
prior to final approval of the project.
6. COMMENT:
What will be run-off impacts to Lower Creek from the construction of McLean Drive
Extension?
RESPONSE:
The run-off from TIP No. U-3813 (McLean Drive Extension) will be channeled into three
(3) existing natural drainage ways. These drainage ways then drain to Lower Creek.
There will be increased run-off into Lower Creek, but the proposed road is approximately
2,000 feet away from Lower Creek, allowing natural drainage ways to lessen the impact on
Lower Creek. As stated in comment #5, the construction drawings, including erosion
control measures, will be approved by NCDOT prior to construction. The Contractor will
be required to construct the road in accordance with the approved plans.
7. COMMENT:
Does NCDOT have any plans to address safety issues at the intersection of Hibriten Drive
and U.S. 64?
RESPONSE:
During discussions with NCDOT following the meeting, NCDOT stated the improvements
to the intersection of Hibriten Drive and U.S. 64 are on the list of improvements. As of
the week of August 27, 2001 a traffic signal has been installed and should be in operation
by September 7, 2001.
13
8. COMMENT:
Why are NCDOT, City of Lenoir, and Caldwell County helping to fund this project when
a private developer will benefit the most?
RESPONSE:
The McLean Drive Extension is an implementation of the State's Transportation
Improvement Program (TIP) and the Caldwell County's Transportation Plan and is
compatible with the City of Lenoir's Land Use and Transportation Plan for the area. The
extension will provide safe access to 300 proposed residential homes and more than
300,000 square feet of retail space. The extension will also provide an overall effective
benefit by reducing congestion at the surrounding intersections.
9. COMMENT:
What will be the impact on existing McLean Drive?
RESPONSE:
A traffic analysis completed by NCDOT in 1998 indicates that there will be only a minimal
increase in traffic along S.R. 1180 (existing McLean Drive) as a result of the construction
of TIP No. U-3813 (McLean Drive Extension).
10. COMMENT:
Why is McLean Drive Extension classified as a minor thoroughfare?
RESPONSE:
In a memo dated May 13, 1998, the Statewide Planning Branch classified the McLean
Drive Extension as a minor thoroughfare because it will serve primarily local traffic. With
the current project termini, the extension will not function as a major radial facility or a
major loop facility.
14
11. COMMENT:
Are there any impacts to existing properties or structures from the construction of McLean
Drive Extension?
RESPONSE:
There are ten (10) individual property owners which will be impacted by the construction
of TIP No. U-3813.
At this time none of the easements / right of ways have been obtained. The City of Lenoir
will be contacting the impacted property owners to discuss these issues.
12. COMMENT:
Why were the citizens not informed about the project until now?
RESPONSE:
The process for developing a project like this is very long. The planning documents have
to be completed in order to have appropriate information to provide to the public. This
project has been discussed on several occasions at the City of Lenoir Council meetings and
the Caldwell County Commissioner's meetings. The purpose of the Citizens Informational
Workshop on February 15, 2001 was to present the detailed plans to the public as required
by NCDOT.
13. COMMENT:
Please install traffic signals at the intersections of SR 1180 (McLean Drive Extension) and
SR 1178 (Hibriten Drive) and SR 1178 and U.S. 64.
15
RESPONSE:
At this time, there are no plans to install a traffic signal at the intersection of TIP No. U-
3813 (McLean Drive Extension) and Hibriten Drive. As with all intersections, NCDOT
will continue to evaluate the operation of the intersection.
During discussions with NCDOT following the meeting, NCDOT stated the improvements
to the intersection of SR 1178 (Hibriten Drive) and U.S. 64 are on the list of
improvements. As of the week of August 27, 2001 a traffic signal has been installed and
should be in operation by September 7, 2001.
14. COMMENT:
How will the intersection at McLean Drive Extension and Hibriten Drive impact traffic
flow for current users of Hibriten? (i.e. new left and right turns for straight thru traffic on
Hibriten)
RESPONSE:
TIP No. U-3813 (McLean Drive Extension) / Hibriten intersection will function as a "T"
intersection. The traffic heading south bound on Hibriten Drive can either continue
straight on McLean Drive Extension or utilize a left turn lane and turn left to continue on
existing Hibriten Drive. The traffic heading north bound on Hibriten Drive will have to
stop and turn right to continue on Hibriten Drive or turn left to get on TIP No. U-3813
(McLean Drive Extension).
15. COMMENT:
Will there be a new traffic signal installed at McLean Drive Extension and Hibriten Drive?
16
RESPONSE:
At this time, there are no plans to install a traffic signal at the intersection of TIP No. U-
3813 (McLean Drive Extension) and Hibriten Drive. As with all intersections, NCDOT
will continue to evaluate the operation of the intersection.
11. Revisions to the Environmental Assessment
Since the approval of the State Environmental Assessment, the McLean Drive Extension
project has been split into two projects. The portion of the project from US 321 to Station
15 +00 is approved for construction as a driveway permit through the Division office. This
portion is under construction by a private developer, but will be turned over to NCDOT
upon completion of the remaining portion of McLean Drive Extension.
The proposed project will displace one residential structure. Prior to final approval, the
City of Lenoir must secure an easement or ownership of property.
The approved Environmental Assessment identified four (4) streams within the project
limits. Upon further investigation only three (3) are flowing streams as identified on the
USGS map. The portion of the McLean Drive Extension from Station 15 +00 to Hibriten
Drive includes one stream crossing. This portion of the roadway construction will impact
280 L.F. of stream. The mitigation for the impacted stream will be from a mitigation plan
or on a compensatory basis.
A private developer is constructing the portion of McLean Drive Extension from US 321 to
Station 15 +00. The private developer applied for and was granted a 401 Water Quality
Certification for 480 L.F. of stream mitigation on January 8, 1999 (DWQ Project
#980726) for two of the three streams impacted. Payment in the amount of $60,000 was
paid to the Wetlands Restoration Program on January 8, 1999.
17
12. Basis for Finding of No Significant Impact
Based upon a study of the proposed project as documented in the Environmental
Assessment, and upon comments received from Federal, State and Local agencies, it is the
finding of the North Carolina Department of Transportation that the project will not have
significant impact upon the human or natural environment. The project is consistent with
plans and goals that have been adopted by the appropriate local governments and the State
of North Carolina. Therefore, an environmental impact statement will not be required.

MEMORANDUM
To: Melba McGee, Environmental Coordinator
NCDENR, Office of Legislative & Intergovernmental Affairs
Through: John.Dorney, NC Division of Water Qualit
From: Cynthia F. Van Der Wiele U&J
Subject: Comments for SR 1180 (McLean Drive) Extension, from US 321 to SR 1178
(Hibriten Drive) in Caldwell County, State Project No. 9.8111589, TIP Project
No. U-3813.
This letter is in reference to your request for comments dated October30, 2000. Preliminary
analysis of the project reveals that the proposed project will impact six streams in the Catawba
River Basin; the recommended alternative will have some wetland impacts.
The Division of Water Quality requests that NCDOT consider the following environmental
issues for the proposed project:
A. NCDOT should anticipate the potential for 50' stream buffers in the Catawba River Basin
and plan the roadway design accordingly.
B. There should be a discussion on mitigation plans for unavoidable impacts. If mitigation is
required, it is preferable to present a conceptual (if not finalized) mitigation plan with the
environmental documentation. While the NCDWQ realizes that this may not always be
practical, it should be noted that for projects requiring mitigation, appropriate mitigation
plans will be required prior to issuance of a 401 Water Quality Certification.
C. DWQ prefers replacement of bridges with bridges. DOT should not install the bridge bents
in the creek, to the maximum extent practicable. If the new structure is to be a culvert, it
should be countersunk one foot, or to the maximum extent practicable, in order to allow
unimpeded fish and other aquatic organisms passage through the crossing.
D. When practical, the DWQ requests that bridges be replaced on the existing location with
road closure. If a detour proves necessary, remediation measures in accordance with the
NCDWQ requirements for General 401 Certification 2726/Nationwide Permit No. 33
(Temporary Construction, Access and Dewatering) must be followed.
E. Wetland and stream impacts should be avoided (including sediment and erosion control
structures/measures) to the maximum extent practical. If this is not possible, alternatives
that minimize wetland impacts should be chosen.

DATE: Novurnbur 21, 2000
SUBJECT: North Carolina Department of Transportation (NCDOT) Environmental Asscssmont
(EA) for the SR 1 I80 (McLean Drive) extension, from US 321 to SR 1178 (Hibrizcn
Drive), Caldwell County, North Carolina- TCP No. U-3 U 3, SCTT project No.
01-E-0286.
Staff biologists with the N. C. Wildlife Resources Commission have reviewed the subject. EA and
are familiar with habitat values in the project area. The purpose of this review was to assess project
impacts to fish and wildlife resources. Our comments are provided in accordance with certain provisions
of the: North Carolina Environmental Policy Act (G.S. 113A-1 et seq., as amended; 1 NGAC; 25).
NCDOT proposes to extend SR 1180 from US 321 to SR 1178. The total project length is
approximately 0.98 miles. Impacts to wetlands are expected to total approximately 0.05 acres wizlt 1,788
linear feet of stream impacts expected.
We have reviewed the data contained in the EA. We do not object to the project as proposed.
NCDOT should lcx)k for wayv to minimize impacts to streams. Host Management Practices for the
protection of Surface Waters should be strictly followed, At this time, we concur with the EA for thiq
project.
Thank you for the opportunity to comment on this EA. If we can be of any further assistance please
