As-Built Report for the Greene Mitigation Site on Goose
Creek, Mecklenburg County
Prepared for the

• This as-built report is submitted as partial fulfillment of the off-site stream mitigation
agreement between the North Carolina Department of Transportation (DOT) and North Carolina
Wildlife Resources Commission (WRC) for the R-2420 B road improvement project in
Mecklenburg County. Under this agreement, a total of 903 linear feet of stream mitigation is
required by the United States Army Corps of Engineers (USACE) and the North Carolina
Division of Water Quality (DWQ). The purpose of this report is to summarize those practices
used for bank stabilization and habitat enhancement along 783 linear feet of Goose Creek known
as the Greene mitigation site, Mecklenburg County (Figure 1). Mickey and Scott (2003)
described pre-construction site conditions and project objectives.
Mussel surveys
The Carolina heelsplitter Lasmigona decorata, a federally endangered freshwater mussel, is
found in Goose Creek. Approximately 4.5 miles of Goose Creek have been designated as critical
habitat for this species. This area extends from the NC 218 bridge in Union County to its
confluence with the Rocky River. The Greene mitigation site is located several miles upstream
of the designated critical habitat area. To ensure that the Carolina heelsplitter was not present at
the Greene mitigation site, a mussel survey was conducted on March 18, 2004 by the Catena
Group using batiscopes and tactile surveys along the banks (Savidge 2004). The Carolina
heelsplitter was not found at the site, however, one individual of the Carolina creekshell Villosa
vaughaniana (Federal species of concern and North Carolina endangered species) was found
upstream of Country Woods Drive, outside of the mitigation site impact area (Savidge 2004).
• An USACE permit condition also required the WRC to conduct a mussel survey at the site
immediately before construction started. Any mussels found at this time or during construction
would be relocated upstream of the construction area. On January 10, 2005, WRC nongame
aqua.tic biologists conducted a mussel search. No live mussels were found; however, one
Carolina creekshell shell was located and moved. During construction, no mussels or mussel
shells were observed.
Conservation Easement and Land Purchases
In order to ensure long term protection of the site, NCDOT obtained a 50 ft buffer
conservation easement (CE) totaling 0.47 acres from James and Christy Tyndal, and purchased
1.58 acres from Lisa Gabbazd and 3.71 acres from George and Linda Greene (Figure 2).
Riparian buffer widths range from 100 ft to >300 ft along the purchased properties. The CE and
land purchases permanently protect 5.75 acres and encompass 783 lineaz ft of Goose Creek.
Right-of-way access to the site is from Country Woods Drive (SR 4220), which borders the
northern end of the site. The site will be maintained by the WRC in perpetuity.
Site Improvements
Channel Modifications
Construction was carried out through an informal contract with Todd Hodges Construction of
• Patterson, N.C. The contractor provided a dump truck, loader, and trackhoe with hydraulic
• thumb. Access to the site was through a temporary construction access along an old road bed off
Country Woods Drive. Before the contractor could move to the site, the local DOT maintenance
shop had to remove a guard rail and install one 12 inch and two 36 inch corrugated metal
culverts in ephemeral stream channels to allow site access. Gravel and ballast stone were then
placed over the pipes and on the temporary access road. Stream work began on February 8 and
was completed on February 23, 2005.
Six rock vanes, two rock toe benches, three root wad structures, and four log structures were
installed to prevent channel headcutting, to divert flows away from streambanks, and to create or
maintain pool habitat (Table 1, Appendix 1). Large footer rocks were installed to support top
boulders in the vanes. Large boulders were also placed behind root wad structures and used as
log structure anchors. Holes were dug below the vanes and root wads to hasten and maintain
pool formation. Excess streambed materials were excavated at rock vanes and placed upstream
of the structure neaz the bank where natural deposition would be expected. Rock vanes were
used to divert water away from eroding banks and for habitat diversity. In addition to these
structures, several existing large boulders were repositioned to direct flows away from
streamba.nks. At seven locations totaling 6751inear feet, streambanks were reshaped on a 1:1 or
2:1 slope to eliminate vertical, eroding banks (Table 1, Appendix 1). At six of the bank sites a
bankfull bench was constructed and the bank reshaped on a 1:1 or 2:1 slope (Table 1, Appendix
1). By the end of each working day, all disturbed soils were seeded, limed and fertilized, and
covered with erosion control matting or with straw.
• The as-built survey, conducted on March 2, 3 and 14, 2005, included a longitudinal profile,
eight channel cross-sections, pebble counts, and establishment of vegetation monitoring plots.
The purpose of the as-built survey is to establish post-construction baselme data that can be
compared with future surveys to monitor channel stability and vegetation survival. A water level
staff gage is located in the lower right corner (facing downstream) of the multi-cell box culvert at
station 0+00. The water level at the time of the as-built survey was 0.18 ft.
The pre-construction longitudinal survey was 773 ft in length whereas the as-built survey
began at station 1+10 and ended at station 7+78, a total of 668 ft(Figure 3). The as-built survey
did not include the first 109 ft of the project site since no stream work occurred in this section.
The pre-construction survey found 49% of the stream was pool habitat whereas the as-built
survey contained 37% pool habitat. The reason for the decrease in pool habitat between the two
surveys is directly related to two factors. First, the pre-construction survey identified a long
shallow pool from stations 3+52 — 4+60 whereas the as-built survey found a pool — riffle — run —
pool complex at the same stations. Second, the pre-construction survey contained a long pool
that had developed behind a large log/debris jam (Figure 3) from stations 4+82 — 5+68. This
log/debris jam is no longer present and the as built survey identified a pool — riffle — pool — riffle
— pool — run complex at these same stations. There is a rapid rise in the thalweg at the head of a
riffle at station 6+24(Figure 3). This 0.5 ft rise is attributed to the presence of bedrock located in
the pool above this station.
Eight cross-sections were established for the as-built survey (Figure 4). Two cross-sections
were located at pools (Figures 4.5, 4.6) and six at riffles (Figures 4.1, 4.2, 4.3, 4.4, 4.7, and 4.8).
• Data from the six riffle cross-sections was used to determine the stream type following
2
• construction (Table 2). The pre-construction survey (Mickey and Scott 2003) classified the
stream at the Crreene site as an unstable F4 and G4 stream type (Rosgen 1996). Using the North
Carolina rural regional curve data (RRC) (Hannan 1999), the as-built survey classified the
constructed stream reach as a stable F4 at two locations and a B4c at the other four locations
(Table 2). The project goal to construct a stable F4 and C4 channel through this reach was
achieved. However, when comparing the same six riffle cross-sections to the North Carolina
urban regional curve data (LTRC) (Doll et al. 2002), four of the six cross-sections are C4 and two
are slightly entrenched E4 stream types (Table 3). The reason for using the RRC and URC is
that the present condition of the stream channel alludes to the stream's stable F4 and B4c
conditions evolving in an urban setting to stable C4 and E4 channels. The Goose Creek
watershed contains approximately 10% impervious area (M. Fowlkes, personal communication).
With the completion of the I-485 project, the area is ra,pidly transforming from a rural to urban
landscape. The C4 and E4 channels are more representative of the newly constructed channel
cross-sections (Figure 4).
Channel bed material was analyzed using the reachwide pebble count and cross-section
survey methods (NCSRI 2003). Riffle pebble counts were conducted in the vicinity of cross-
section stations 1+39 and 6+24. The D5� observed in the two riffles and reach ranged from 11.7
mm to 25.4 mm with a weighted dso of 18.4 mm (Figure 5). Sixty-four percent of the bed
material in this reach of Goose Creek is considered gravel, 17 % silt and sand, and 16 % cobble
(Figure 5).
• Riparian Improvements
Disturbed streambanks and soil disposal areas were seeded with a WRC native riparian mix
(Mickey and Hining 2003) and a cover crop of winter wheat and rye. After seeding, bare soils
were limed, fertilized, and covered with erosion control blankets or with straw. Erosion control
blankets were used to stabilize the soil surface on steep slopes until vegetation can become
established.
A total of 981 stems (live stakes and rooted trees) were planted during and following
construction (Table 4). Sixty-four percent of the planted stems were composed of silky dogwood
Cornus amomum (28%) and silky willow Salix sericea (36%). Three vegetation plots totaling
0.085 acres and 195 stems (20% of total planted) were established on March 3, 2005 (Table 5,
Appendix 2). These three plots will be used to determine stem survival rates through the
monitoring period. The vegetation plots can also be used to monitor volunteer stem growth.
Based on planting guidelines established for mitigation sites, a total of 320 stems/acre should be
counted through year three (LTSACE 2003). At the Greene site, approximately 0.8 acres were
disturbed during construction, requiring that 256 stems be counted at the site in the winter of
2008.
The terrestrial exotic invasive plants of wild olive Elaeagnus spp. and Chinese privet
Ligustrum sinense exist at the site. These invasive species need to be monitored and if they
become a nuisance, some form of cutting/chemical control may be required.
u
• Project Costs
The WRC project cost for stream enhancement work was $30, 454.17 or $ 38.89 per lineaz
foot of stream enhancement (Table 6). Project cost includes: meetings with landowners, DOT,
DWQ, and U.S. Fish and Wildlife Service personnel; field survey work; preparation of project
conceptual design; construction and as-built report; tree purchase and planting; erosion control
materials (seed, fertilizer, fabric); and WRC personnel and administrative costs. Taking into
account DOT personnel, equipment, materials expenses, and CE and land purchase costs, project
costs increase to $101,871.36 or $131.79 per foot (Table 6). Site monitoring and repair costs
will be added to the cost total as they accrue during the monitoring period.
Summary
Using natural stream design techniques, stream dimension and profile was improved at this
site. Based on North Carolina RRC data (Harmon et al. 1999), an unstable F4 and G4 stream
type was converted to a stable F4, B4c stream type. However, when taking into account that the
watershed is rapidly urbanizing, North Carolina URC data (Doll et al. 2002), indicate this reach
of Goose Creek would be classified as a C4 and slightly entrenched E4 stream type. Water
quality will be improved through reduced sedimentation from previously eroding banks. In-
stream habitat for fish and aquatic invertebrates has been increased with the installation of rock
vanes, log vanes, and root wads. Both aquatic and terrestrial species will benefit with the return
of a functioning riparian corridor. Stream aesthetics have also been improved. Trends in pool
• development and channel narrowing tend to be positive from pre-construction to as-built
conditions. However, monitoring will be necessary to determine if the scour action created by
rock vanes, log vanes, and root wads can be maintasned or increased. The reshaped banks should
remain stable following bankfull and flood events.

2003 Monitoring Report for the Miller et al.
Mitigation Site on Meat Camp Creek, Watauga
County
Prepared for the
North Carolina Department of Transportation Stream Mitigation
Program
Transportation Improvement Project R-529
Joseph H. Mickey, Jr.
Staci S. Hining
North Carolina Wildlife Resources Commission
Division of Inland Fisheries
December 2003
This 2003 monitoring report is submitted as partial fulfillment of the off-site stream
mitigation agreement between the North Carolina Department of Transportation (DOT) and
North Carolina Wildlife Resources Commission (WRC) for the R-529 US 421 road improvement
project in Watuaga County. Under this agreement, a total of 14,8141inear feet of stream
mitigation is required by the United States Army Corps of Engineers (COE) and 7,407 linear feet
of mitigation is required by the North Carolina Division of Water Quality (DWQ)- The purpose
of this report is to summarize the 2003 monitoring data collected from 6521inear feet of Meat
Camp Creek located on the Miller et al. Property, Watauga County (Figure 1). Mickey and
Scott (2002) described pre-construction survey methods, site conditions, and project objectives.
Monitoring data was compared with data submitted in the 2003 as-built report (Mickey and
Hining 2003).
Site Improvements
Channel Mod�cations
The first year monitoring survey was completed on October 21, 2003 and included
longitudinal profile, pebble count, and five channel cross-sections. The longitudinal profile has
remained stable since the as-built survey (Figure 2). A total of 14 structures (2 rock weirs, 11
rock vanes and one log vane) were constructed (Table 1) with approximate locations shown on
the longitudinal profile (Figure 2). The pre-construction and post construction riffle D-50's were
45 mm and 46.6 mm (coarse gravel) (Mickey and Hining 2003), respectively. The monitoring
pebble count D-50 was 37.2 mm (Figure 3)_ While the monitoring D-50 was slightly smaller
than the post and as-built D-50, it is still in the coarse gravel range. The five cross-sections have
remained stable since construction and have experienced very little change since the as-built
survey (Figures 4.1-4.5).
Riparian Improvements
A total of 177 live stakes and bare root nursery trees were planted on March 17, 2003 (Table
2). Plantings included tag alder Alnus serrulata, silky dogwood Cornus amomum, silky willow
Salix sericea, black walnut Juglans nigra, and black locust Robirur pseudoacacia . Due to the
small size of the plantings and high weed growth at the time of the monitoring survey, a survival
count of live stakes and bare root nursery stock was not conducted. A vegetation count will be
conducted during March of 2004.
Livestock Exclusion
The livestock exclusion plan, two water tanks and fencing, is functioning as planned.
Livestock are no longer drinking from Meat Camp Creek or two small spring seeps located on
the Miller property.
Conclusion
Since construction in September 2002, the Meat Camp Creek mitigation site has remained
stable. Rock weirs, rock and log vanes are functioning as planned and have created more stable
2
streambanks at this location. Water quality should be improved through reduced sedimentation
from eroding streambanks and exclusion of livestock from the riparian zone. In-stream habitat
for fish and aquatic invertebrates has been increased with the installation of rock weirs, rock and
log vanes and root wads. The second year of monitoring will be conducted during
October/November 2004.

SUMMARY
S.1 DESCRIPTION OF ACTION
The proposed action is a Transportation Improvement Project on
the eastern limits of the Town of Boone and in Watauga County.
Watauga County is located in the northwest portion of North
Carolina within the Blue Ridge Mountains. Boone is located
within Watauga County and serves as the seat of County
Government. It is the only municipality in the county with a
population greater than 500. The action consists of the
improvement of US 421 from the intersection of US 421/NC 194
within the Town of Boone to just west of the South Fork New River
in Watauga County. The general location of the action is shown
on Exhibit l.l.
The proposed US 421 improvement will be a five-lane facilit� with
an approximate length of one mile. This report docum2nts the
ideritification of five possible construction alternatives. Three
of these alternatives, as well as the "no-build" alternative, are
evaluated with respect to feasibility, cost, environmental
impact, and mitigation.
US 421 serv�s as the primary transportation route linking Boone
to eastern North Carolina. Over the past 20 years, this area has
experienced a substantial increase in traffic volumes. This
increase can be attributed largely to the popularity of the area
as a tourist attraction. Each year, thousands of visitors from
i
the piedmont and coastal regions of the state travel to the Blue
Ridge Mountains to view "the changing of the leaves," enjoy the
many theme parks, or ski.
The eastern section of Boone and the surrounding area are rapidly
being developed. Several proposed commercial service areas just
west of the South Fork New River Bridge are currently in the
planning stages. Year 2008 traffic studies indicate the need for
a multi-lane facility to accommodate these developments. The
existing US 421 cannot" effectively serve this demand. The
improvement of this roadway will ensure that adequate trans-
portation facilities are available to accommodate anticipated
future growth patterns.
S.2 DESCRIPTION OF ALTERNATIVES
The "no-build" alternative and five construction alternatives
were evaluated for this report. The alternatives considered are
shown in Exhibit 2.1 and are as follows:
Alternative A- begins- at NC 194 and extends northeast around
Mount Lawn Memorial Cemetery following along the
alignment of SR 1329 (Perkinsville Drive) to
connect with existing US 421 west of SR 1516.
Alternative B- begins at the intersection of US 421 and NC 194
and extends southeasterly along Spruce Street to
connect with US 421 just west of the South Fork
New River Bridge.
ii
Alternative C- begins at NC 194 and extends southeasterly just
north of Spruce Street to connect with US 421
just west of the South Fork New River Bridge.
Alternative D- begins at NC 194 and follows existing alignment
to the South Fork New River Bridge. Existing
pavement would be maintained and widened.
Alternative E- begins at NC 194 and follows the existing
alignment to the South Fork New River Bridge.
Existing pavement would be removed at designated
points and the grades lowered or raised as
required in order to maintain a 55-mph design
speed.
S.3 ALTERNATIVES CONSIDERED FOR DETAILED STUDY
Alternatives A, B, and E were selected for detailed evaluation
based on environmental impacts, land use compatibility, and
constructability. Functional design plans and profiles were
prepared for each of the study alternatives and served as the
basis for the cost-benefit analysis.
S.4 ENVIRONMENTAL IMPACTS
The significant impacts and cost estimates evaluated for each
alternative ate itemized in Table 5.1.

S.5 PERMITS REQUIRED
No applicable state or federal permits are required.
S.6 PREFERRED ALTERNATIVE
Although the final selection of an alternative will not be made
until after comments from the public hearing have been
considered, the obvious advantages of Alternative A resulted in
its identification as the preferred alternative. The advantages
of Alternative A are as follows:
l. It satisfies the need for an improved transportation
facility.
2. The location is supported by most local residents and
property owners.
3. The associated right-of-way and construction costs are
minimized.
4. The fewest relocations of residences and businesses are
required.

CHAPTER 1
PURPOSE OF AND NEED FOR ACTION
This project is designed to meet the growing transportation needs
of Boone and Watauga County and to provide for their planned
development. This study.substantiates the need for improving US
421 through an evaluation of the traffic demand and the
transportation system within the study area.
1.1 PROJECT SETTING
' The Town of Boone is located in Watauga County in the
northwestern portion of North Carolina. Watauga County is
' located within the scenic Blue Ridge Mountains which form part of
the Southern Appalachian Mountain Range. Exhibit l.l shows the
' county and study area in relation to the state.
�
�
'
'
'
The town's location allows for a variety of employment
opportunities supported by the tourist trade and the winter
skiing r�sorts.
The population of Boone tripled in the twenty-five years between
1960 and 1985, growing from 3,686 to 11,360. Much of this growth
can be attributed to the economic opportunities provided by
tourism.
' Appalachian State University (ASU), founded in 1899, also has
been a catalyst for Boone's growth. ASU's student population has
'
�
' 1-1
almost quadrupled in the twenty-five years between 1960 and 1985,
growing from 2,584 to 10,204.
1.2 SOCIAL AND ECONOMIC DEVELOPMENT
US 421 is the only east-west roadway with direct access to the
Boone area. During the past several decades, the traffic volumes
on this highway have increased dramatically. The level of
operation and safety of US 421 have been compromised by this
increase, which was generated largely by summer tourism, part-
time residents, university students, and winter ski resort
enthusiasts. These traffic generators are a vital part of the
economy of the region and crucial to the future well being of its
citizens.
During the past ten years, the county has seen its employment
base shift from manufacturing and industrial to service and
tourism. One reason for this loss of industry is the unsafe,
limited, two-lane access provided by US 421.
1.3 TRANSPORTATION DEMAND
1.3.1 Existing Year 1988 and Design Year 2008 No-Build Traffic
Volumes
Average daily traffic (ADT) volumes for Years 1988 and 2008 on US
421 and NC 194 are shown in Exhibit 1.2. The highest volume
within the study limits, 13,600 and 24,600 vehicles per day (vpd)
for Years 1988 and 2008 respectively, occurs on US 421 east of
the intersection with NC 194.

Table 1.1 presents the ADT, estimated peak hour traffic volume,
and the level-of-service (LOS) for US 421 and the US 421/NC 194
intersection. As indicated, US 421 is now operating at LOS E.
It is expected to operate at LOS F in design year 2008.
LOS E describes high driver discomfort, with delays being
experienced greater than 75 percent of the time. The
intersection of US 421/NC 194 is operating at LOS F during peak
hour. At LOS F, excessive delay and queuing of traffic are
experienced.
1.3.2 Accidents
Accident data for the period between January l, 1985, and March
31, 1988, were gathered for the study area. During this three
years and four months time span, a total of 24 accidents, all
non-fatal, occurred at the US 421/NC 194 intersection. Based on
the total number of vehicles entering the intersection, the total
accident rate equates to 105.36� accidents per 100 million
entering vehicles (MEV). This is considerably higher than the
national average of 82- accidents per 100 MEV for T intersections
as reported by the Federal Highway Administration (FHWA).1 The
predominant cause of this abnormally high average accident rate
is the over-capacitation of the intersection.
The total number of vehicles entering the intersection in Design
Year 2008 is projected to be approximately 38,700 per day.
Assuming that the total accident rate will not increase, the
total number of accidents that would occur in Year 2008 is
approximately 12.
1-4
'
� Between the intersection and the South Fork New River Bridge, a
' total of 10 accidents occurred during the study period. This
equals a total accident rate of 148.10 accidents per 100 million
' vehicle miles traveled (MVM). Using the anticipated Design Year
2008 traffic projections for this segment of roadway, the total
' number of accidents would be approximately 23 in Year 2008.
' 1.4 SUMMARY
, Because US 421 is the only highway connecting Boone to eastern
North Carolina, the healthy growth of this area would be
` constrained by the capacity limitations and safety concerns of
' the existing highway.

CHAPTER 2
DESCRIPTION OF ALTERNATIVES
A comprehensive list of possible preliminary alignment alterna-
' tives was developed. They were the "no build" and five
' construction alternatives. During the data gathering and
analysis phase, three of the five construction alternatives were
' selected for detailed study. The following is a description of
the preliminary alignment alternatives and the process for their
' development and rejection or selection for further study.
'
�
'
�
'
�
'
'
'
'
'
'
2.1 NO-BUILD ALTERNATIVE
The No-Build or "do nothing" Alternative is used as a baseline
condition with which to compare all other acceptable
alternatives. Under the "no build" scenario, no major
improvements would be made to the existing US 421 roadway.
Advantages of the "do nothing" Alternative include the following:
- No new capital expenditure.
- No relocation of businesses or houses.
- No traffic delay due to construction.
- No removal of or impact on the biotic communities.
- No increase in ambient noise levels.
However, there are a significant number of disadvantages to the
No-Build Alternative:
- Rapid degeneration of the Level of Service.
- Increased demand on local roads.
2-1
- Increased amount and duration of congestion.
- Higher-than-average number of accidents.
2.2 CONSTRUCTION ALTERNATIVES
Accommodating the area's future traffic demands will require
increasing the capacity of US 421. This can be done by
constructing two additional lanes in the existing US 421 corridor
or by using alternative alignment corridors.
Preliminary Alternative Corridors A through C were developed
using information collected about environmental, land use, and
constructionability factors in the area. These alternatives are
shown in Exhibit 2.1 and were presented for public review at the
first public meeting/workshop held on January 17, 1989.
The preliminary alternatives were then.more specifically analyzed
according to the factors listed in Table 2.1. An evaluation
matrix was used to identify and reject the alternatives that
would provide the fewest benefits and have the greatest negative
environmental impacts. . The basic evaluation methodology used to
compare the corridor alternatives is described in Section 2.3.
Using this process, Alternatives C and D were eliminated. The
remaining corridor segments were studied in greater detail.
2.2.1 Alternative A
Alternative A begins at NC 194 and extends northeast around Mount
Lawn Memorial Cemetery following the alignment of SR 1329

(Perkinsville Drive) and connects with existing US 421 west of SR
1516. At-grade intersections are proposed at the western
terminus of Alternative A with NC 194 and near the eastern
terminus where this alternative meets existing US 421. Exhibit
2.2 shows the proposed intersections for all alternatives.
2.2.2 Alternative B
Alternative B begins at the intersection of US 421 and NC 194 and
extends southeasterly along Spruce Street to connect with US 421
just west of the South Fork New River Bridge. One at-grade
intersection with NC 194 is proposed. Two are proposed on
existing US 421, where Alternative B intersects both its western
and eastern ends.
2.2.3 Alternative E
Alternative E begins at NC 194 and follows the existing alignment
to the South Fork New River Bridge. This alternative would
improve the existing corridor while incorporating a 55-mph design
speed. Although the construction cost to improve the existing
corridor would be less than building on a new corridor, the cost
of traffic control would be much greater. The only possible
detour would be SR 1329, which has inadequate design and capacity
for the large amount of traffic which would have to be detoured
from US 421.
2-4
The existing vertical alignment does not provide sufficient sight
distance to meet the proposed 55-mph design speed. One example
of the vertical alignment deficiency is at the roadway's crest,
approximately midway through the project. To correct this
problem, the vertical curve would need to be lengthened, thus
lowering the roadbed at its crest by over 25 feet.
2.2.4 Opening and Design Year Traffic Projections
An assumed opening year of 1993 and design year of 2008 were
established; the actual opening year would depend on a
construction timetable. Exhibits 2.3 and 2.4 present the
estimated ADT volumes for each alternative corridor alignment and
the intersecting local roads for Opening Year 1993 and Design
Year 2008, respectively. The estimated ADT volumes for
Alternative E for.Years 1993 and 2008, respectively, are the same
as those shown in Exhibit 1.2 for the No-Build Alternative.
Exhibits 2.3 and 2.4 show that traffic volumes are approximately
the same for Alternatives A and B. Traffic projections for
existing US 421 would drop significantly, with only local
traffic using the roadway. For both alternatives, ADT volumes
are estimated at approximately 13,600 and 24,600 vpd for Years
1993 and 2008, respectively.
2-5
2.2.5 Roadway Design Criteria
Roadway design criteria as approved by NCDOT and FHWA are shown
in Table 2.2. These criteria, which are based on Year 2008
traffic projections, indicate that a minimum of five lanes--two-
in each direction with a center turning lane--are needed for the
mainline of US 421. Two typical sections are proposed for all
alternatives, as shown in Exhibit 2.5. The use and location of
the typical sections were determined by topographical consider-
ations and transverse slopes.
Typical Section 1 would be used from the western terminus where
US 421 and NC 194 intersect to the point where the transverse
slope exceeds 0.04. Typical Section 1 would then transition to
Typical Section 2.
2.3 MATRIX EVALUATION OF SECTION ALIGNMENTS
An evaluation matrix was used to compare the alternatives. The
methodology is similar to that used to eliminate the least
beneficial corridor alignment, although more comprehensive. The
four major categories are environmental, land use compatibility,
costs, and traffic services, and each has its own separate matrix
evaluation.
2.3.1 Environmental Categor
This category contains seven factors for evaluation:
* Surface Water Impacts - the calculated effect on surface
water quality;

* Agricultural - the acreage of prime and/or important
farmland within the right-of-way;
* Historical Sites - the number of potentially eligible struc-
tures within the right-of-way and the number of potentially
eligible structures abutting the right-of-way;
* Archaeological Sites - the number of significant sites
within the right-of-way;
* Flora/Fauna - the acreage of natural wildlife habitat and
the number of potentially threatened or endangered species
areas within the right-of-way;
* Ground Water - the calculated effect on ground water
quality; and
* Hazardous Waste or Petroleum Storage Sites - the number of
identified or potential hazardous waste sites located within
the right-of-way.
The Environmental category evaluation matrix is shown in Table
2.3 along with the scale for each of the seven factors. The
higher the number of the scale, the greater the impact. For
example, a high number on the Historical Sites factor scale means
that a great number of historical sites are located within or
adjacent to the right-of-way.
Generally, Alternative E has the fewest negative impacts for all
factors except Hazardous Waste or Petroleum Storage Sites. Alter-
native A has the fewest possible hazardous waste or petroleum
storage sites and falls within the two extremes for surface water

and ground water impacts. Alternative B has the most negative
surface water and ground water impacts and ties with Alternative
E for the number of potential hazardous waste sites.
2.3.2 Land Use Compatibility Category
This category contains five factors for evaluation:
* Parks - the number of parks that are impacted by noise;
* Schools - the number of schools that are impacted by noise;
* Churches - the number of churches that are impacted by
noise;
* Cemeteries - the number of actively visited cemeteries
impacted by noise;
* Subdivisions/Neighborhoods - the number of housing units
approaching a noise level of 67 dBA plus the number of units
having increased noise levels above existing ambient con-
ditions of 15 dBA or more; and
* Commercial - the number of commercial sites, including
government facilities, approaching a noise level of 72 dBA
plus the number of units having increased noise levels above
existing ambient conditions of 15 dBA or more.
The Land Use category evaluation matrix is shown in Table 2.4.
The number of sites experiencing negative noise impacts for each
alternative are as indicated.

Alternative B follows an undeveloped corridor throughout much of
its eastern half and so has the fewest negative noise impacts.
Alternative A includes the greatest number of residences that
experience a negative noise impact, but is tied with Alternative
B for the fewest number of commercial sites. As discussed in
Section 4.5.1 of this report, the majority of the sites
identified in Table 2.4 as approaching undesirable noise levels
are also impacted by noise under the No-Build Alternative. In
some instances, the construction alternative even results in a
reduction in the predicted noise levels.
2.3.3 Costs Category
This category contains five factors for evaluation:
* Construction - the estimated cost of the roadway, inter-
sections with local streets, bridges, culverts, drainage,
and earthwork;
* Relocation - the estimated cost of business and residential
relocations;
* Right-of-Way - the estimated cost of right-of-way
acquisition; and
* Utilities - the estimated cost of utility relocation.
* Total Costs - the summation of all costs.
The Costs category evaluation matrix is shown in Table 2.5. All
alternatives are ranked from the most expensive at 3 to the least

expensive at 1. The scale was derived from construction costs
estimated as shown in Table 2.9. Alternative A has the least
total cost, followed by Alternative B, with Alternative E having
the greatest total cost.
2.3.4 Traffic Services Category
This category involves the analysis of intersection LOS as shown
in Table 2.6. If an unsignalized intersection would operate
acceptably for the assumed Opening Year 1993 or Design Year 2008,
it was so designated. If not, a signalized intersection analysis
was performed to determine the LOS at which the signalized
intersection would operate.
The LOS analysis follows the methodology outlined in the 1985
Highway Capacity Manual (see Appendix A). Table 2.7 shows the
expected average running speed for each alternative during peak
and off-peak hours. Both Tables 2.6 and 2.7 show that all of the
alternatives will operate at a vastly improved and acceptable
LOS.
2.3.5 Safety
Based on accident data gathered for existing US 421, accident
rates and average annual accidents were calculated for the
No-Build Alternative for Opening Year 1993 and Design Year 2008.
Average annual accidents were also calculated for each of the
other alternatives using accident rates provided by FHWA.1 The
results are shown in Table 2.8.

2-17
All improvement alternatives reduce the total number of
accidents, principally at the intersection of US 421/NC 194. The
increase in total number of accidents for Alternatives A and B
over Alternative E is due to the greater length of the
alternative corridor.
2.3.6 Review of Matrix Analysis
The results of the matrix analysis will be used in conjunction
with the cost-effectiveness analysis and public and agency
comments to identify a recommended alignment subsequent to the
public hearing.
2.4 ROADWAY COST ESTIMATE
Estimated construction and right-of-way costs are presented in
Table 2.9. Estimated costs (in 1988 dollars) range from a total
high of $7,685,000 for construction of Alternative E to
$5,855,000 for construction of Alternative A.
2.5 USER BENEFIT ANALYSIS
A user benefit cost analysis was conducted to help determine the
economic benefits of each alternative. The following paragraphs
summarize a more detailed report document, User Benefit Analysis
Technical Memorandum, which is appended by reference.
The purpose of the user benefit costs analysis is to determine
whether the expected economic benefits during the design period

will exceed the estimated costs for the same period. Common
discount rates are used to compare the alternatives according to
guidelines published by the American Association of State Highway
and Transportation Officials (AASHTO).2
Economic benefits consist of any reduction in road user expenses
expected to occur as a result of drivers operating their vehicles
on a safer, less congested, and more efficient highway. This
includes personal time with its corresponding dollar value,
vehicle operating expenses, and accident reductions. Project
costs include engineering, right-of-way, construction and
maintenance costs of the proposed alternative minus costs
associated with maintaining the existing roadway.
Table 2.10 presents the results of this analysis, which uses the
Benefit/Cost Ratio as the measure of economic desirability. The
Benefit/Cost Ratio is the ratio of the net present value of the
total estimated annual benefits to the net present value of the
estimated annual costs. An investment is considered to be
financially desirable if the benefit/cost ratio is greater than
1.0. As shown in Table 2.10, all these alternatives are
considered to be financially desirable due to the benefit/cost
ratio being greater than 1.0. Alternative A shows the greatest
benefit/cost ratio at all of the three discount rates, and thus
would be considered as the alternative with the greatest
desirability.

2.6 PREFERRED ALTERNATE
While the selection of an alternative will not be made until the
impacts and comments from the Public Hearing and this draft
environmental impact statement have been fully evaluated,
Alternative A was identified as the preferred alternative.
The Alternative A alignment will serve the future traffic needs
of Boone and Watauga County.
Alternative A will have minimal impact on the natural environ-
ment. As shown in Table 2.3, Alternative A impacts no historical
or archaeological sites', and has the fewest possible hazardous
waste or petroleum storage sites within its proposed right-of-
way.
Alternative A also has a lower construction and right-of-way cost
than Alternatives B and E. The roadway cost and right-of-way
cost were discussed and summarized in Section 2.4 and Table 2.9.
As shown in Table 2.10, Alternative A also has the greatest
benefit/cost ratio.
The advanced planning stages associated with Alternative A, lower
cost, minimal environmental impacts, and service to the area all
contributed to the selection of Alternative A as the preferred
alternative.

AFFECTED ENVIRONMENT
An overall, comprehensive� inventory and evaluation of the
� economic, social, cultural, natural, and physical environment in
' the study area and Watauga County was performed. These data
concerning the existing conditions, when contrasted with historic
� information, will facilitate the assessment of the proposed US
. 421 widening and realignment alternatives. A definition of the
' study boundaries is contained in Chapter 1.
' 3.1 SOCIOECONOMIC CHARACTERISTICS
� 3.1.1 Economic Characteristics
' During the past three decades, the economy of Watauga County has
been in transition from an agricultural base to a more
' diversified and stable combination of manufacturing, retail,
educational, service, and tourism industries. More recently,
� this trend has shifted with a continuing heavy dependence on
� retail and tourism but a significant decline in manufacturing, as
described in Watauga County Planning Implementation Policies,

offers wages well below those of manufacturing. As a result, per
capita and median family income levels in Watauga County are also
lower than the state average, as shown in Table 3.2. Low income
levels coupled with increasing land costs have resulted in county
residents, especially young people, leaving the area in search of
employment opportunities and higher wages.2 Poor transportation
and accessibility have influenced and will continue to influence
this trend.
Employment by industry group in 1984 and 1985 for Watauga County
is shown in Table 3.3, which highlights the downward trend of the
manufacturing sector and the substantial increases in the tourism
and service sectors.
Additional evidence of this trend toward a non-manufacturing-
based economy is provided in Table 3.4. Again, a decline in
manufacturing employment to a non-manufacturing base is evident,
reflecting the national trend toward a more service-oriented
economy. The table shows that while 7.9 percent of the labor
force was involved in manufacturing in 1980, this figure dropped
to 4.9 percent in 1986. During the same period, non-agricultural
wage and service employment remained constant at 50 percent,
while non-manufacturing employment increased from 42 percent to
45.1 percent. Manufacturing provides 31.6 percent3 of statewide
employment, as compared to Watauga County's 4.9 percent.

3.1.2 Watauga County Population Characteristics
The population of Watauga County continues to increase as shown
in Table 3.7. In addition to full-time residents, the county,
� due to its scenic beauty and recreational opportunities, had a
part-time resident population of approximately 6,786 residents in
� 1980 and an estimated population of 8,660 in 1985.4 From 1980
through 1985, the permanent population increased by 5.6 percent,
while part-time residents increased by 27.6 percent. Watauga
County's permanent resident growth rate is approximately 35
percent of the state growth rate, while its rate for part-time
residents is almost twice that of the state. Statewide
population growth rates are shown in Table 3.8.
Further comparison of Watauga County population statistics with
state figures reveals the following:
- Population growth projections between Years 1990 and 2000
indicate a county growth rate of approximately 11.2 percent,
� which is slightly higher than the statewide increase of 9.6
� percent (see Tables 3.7 and 3.9).

1 3.2 COMPREHENSIVE LAND USE AND TRANSPORTATION PLANNING
�
�
Land use planning for Watauga County and US 421 falls under the
jurisdiction of the Region D Council of Governments, which
published the Regional Land Potential Study and Land Development
Plan in 1978. Between 1971 and 1981, the county adopted a
building code and subdivision regulations; employed building
inspectors, a subdivision coordinator, and a county manager; and �
adopted a thoroughfare.plan (for Boone and its immediate vicinity
only). The county has yet to adopt zoning in any portion of its
area not controlled by a municipality.
' Boone published the Boone Land Development Plan in 1977, adopted
a zoning ordinance in 1980, and has more recently adopted a
, thoroughfare plan. The town zones within the town limits only
and not within the one-mile extraterritorial area.

The U.S. Department of Agriculture (USDA) Soil Conservation
Service has published An Appraisal of Potentials for Outdoor
Recreational Development (1974), which covers historic sites,
scenic sites, soils, lakes, etc., in Watauga County. Some of
this information is included in other planning documents.�
3.2.1 Existing Land Use
Exhibit 3.1 depicts five categories of land use within the study
area: commercial, residential, open field/agricultural, church,
and cemetery. The residential category contains all housing
types, including mobile homes. Following is a general
description of the land use types traversed by each alternative:
1 Alternative A- This alternative, running in conjunction with and
to the north of the existing US 421 corridor, involves strip and
1 scattered commercial, residential, cemetery, and church land
uses. In addition, some agricultural land and woodland would be
� impacted by this alternative.
'
,
r
�
'
�
'
Alternative B- This alternative is similar to Alternative A
except that it takes a southerly route from that of the existing
US 421 corridor. Included land uses are scattered commercial
and residential, open field/agricultural, and a small amount of
woodland.
3-15
Alternative E- The road improvements within the existing
right-of-way will have the greatest impact on existing man-made
facilities. This alternative would require the relocation of
many businesses and residences. Minimal open field/agricultural
and woodland areas are located adjacent to the existing roadway.
3.2.2 Land Use Planning
In 1988, the Watauga County Planning Implementation Policies were
adopted, which provided a vehicle for citizen participation in
the planning process. Citizens were polled regarding their
concerns about the county's past, present, and future growth as
related to its natural and man-made environment.

Although the report does not address specific land use, it
, documents the county's growth as perceived by its inhabitants.
According to the report, the most desired improvement was in the

3.3 CULTURAL RESOURCES
Cultural features within the study area include existing
churches, schools, cemeteries, and public and private open space,
as shown in Exhibit 3.2.
3.3.1 Schools
Watauga County Schools' Administrative Unit is composed of eight
elementary schools and one consolidated high school. A center
for exceptional children is located at Hardin Fork Elementary
School, and Appalachian State University is located in the Town
of Boone .
3.3.2 Recreational and Leisure Activities
Both the Town of Boone and Watauga County offer a variety of
recreational and leisure activities; however, none of these
facilities is located within the immediate study area.
3-17
3.3.3 Historical and Archaeological Resources
A records search revealed only one archaeological site, and that
was destroyed by residential construction. The only potential
historical site was deemed ineligible for the National Register
of Historic Places due to lack of integrity.8
The archaeological investigation is summarized in a report
entitled An Archaeological Reconnaissance Survey of Proposed US
421 Improvement by Archaeological Research Consultants, and the
historical/architectural investigation is summarized in a report
entitled Historic Structure Survey and Evaluation Report for US
421 Environmental Impact Statement by Ms. Margaret Long
Stephenson, both appended by reference.
3.4 UTILITIES
3.4.1 Electrical Power
The Town of Boone is primarily served by New River Light and
Power Company, which is a distribution utility. The area is also
served by Blue Ridge Electric Membership Corporation, a
transmission and distribution utility, which is the primary
supplier of electric energy in northwest North Carolina.
Electrical power requirements up to 110 kilovolts (kV) are
available. The Town of Boone is looped by a 46-kV transmission
system. Exhibit 3.3 shows existing power transmission lines.
K��:,
'
' New River Light and Power Company is located on Winkler's Creek
Road in Boone and is owned by the Appalachian State University
� Foundation. It serves 6,000 consumers, including the university
' campus. Its primary distribution system is 7,200 volts.
� Blue Ridge Electric Membership Corporation is a cooperative owned
by its consumers. The Watauga District Office is located on US
� 421 South, and the corporate headquarters is located in Lenoir,
North Carolina. The Watauga District provides service to 15,500
jmeters, including the New River system. Its distribution system
� is supplied at 7,200 volts. Two 100-kV transmission lines are
the primary sources for the area, which has a 46-kV transmission
� network.
� 3.4.2 Fuel Oil
Fuel oil is available from several local distributors. Bulk
� supplies are available at competitive prices, primarily from the
' Charlotte, North Carolina area.
, 3.4.3 Natural Gas
Although natural gas is not available in Boone or Watauga County,
' there are three local distributors of propane gas. Suburban
� Propane on Meadowview Drive is the principal supplier within the
town of Boone.

3.4.4 Telephone Service
Telephone service is provided by Southern Bell in Boone and
Skyline Telephone Membership Corporation throughout Watauga
County. Al1 primary long distance carriers serve the area.
3.4.5 Water
The Town of Boone's Municipal Department provides water to
residential and commercial users within the town limits. Users
outside of Boone must rely on drilled wells. Exhibit 3.4 shows
the water lines serving the study area.
3.4.6 Sewer
The Municipal Department also provides residential and commercial
users within Boone with sewage disposal service. Some users
outside of the town limits are also connected to the centralized
sewerage system. Those that are not must rely on underground
septic systems. Exhibit 3.4 also shows sewer lines.
3.4.7 Railroads
There is no rail service directly into Boone; however, piggyback
service is available at Hickory/Conover, approximately 50 miles
away. Frequency of switching service is daily.

3.5 MINERAL RESOURCES
There are presently no operations for mineral extraction in the
study area. Existing urbanization and industrial land use are
prohibitive to rock quarrying. There are no significant
commercial sand, gravel, or clay deposits within the study area,
and the potential for future development of mineral resources is
low.
3.6 PHYSICAL ENVIRONMENT
The North Carolina Environment Policy Act established that all
major actions to be funded by the North Carolina State Government
must be assessed to determine their impact on the environment.
This includes noise levels, air quality, and water quality within
the study area and surrounding regions that may be affected
during and after construction.
3.6.1 Noise
' The principal source o�f noise within the study area is vehicles
from existing US 421. Other sources include construction,
farming, and yard work. Section 4.5.1 of this report presents
�
the anticipated impacts of the construction alternatives on
' existing noise levels.
�J
�
�
'
3-21
3.6.2 Air Quality
The U.S. Environmental Protection Agency (EPA) and the North
Carolina Department of Natural Resources and Community
Development (DNRCD) have established criteria to define air
quality. EPA has established two standards for air quality:
primary and secondary. Primary standards are those levels
required to protect the public health with an adequate margin of
safety. Secondary standards are those levels required to protect
the public health from any known or anticipated adverse effect of
an air pollutant. These criteria are designated as the Ambient
Air Quality Standards (AAQS) and are established for seven air
pollutants: carbon monoxide (CO), lead (Pb), nitrogen dioxide
(NO2), sulfur dioxide (S02), particulate matter (TSP),
particulate matter at or less than 10 microns (PM10), and ozone
(03). These standards and those of the DNRCD are shown in Table
3.11.
Neither EPA nor the DNRCD currently monitors levels of CO, 03,
NO2, TSP, or PM10 in Watauga County or the Town of Boone.
According to the Clean Air Act Amendments of 1977, all areas
within the state are designated as either attainment,
non-attainment, or unclassifiable with respect to the AAQS.
Areas that meet the AAQS are designated as attainment. Areas
where the AAQS are not met are designated as non-attainment. In
non-attainment areas, a State Implementation Plan (SIP) is
developed to bring the area into compliance with the AAQS.

Finally, areas such as the study area where there are no
available data for classification are designated as
unclassifiable. Based on past monitoring, however, the area
should be well within all air quality standards.
3.6.3 Water Quality
Surface Water - The principal water course in the study area is
the South Fork New River. Surface runoff is also collected by
Hardin Creek and an unnamed stream that parallels US 421
approaching the river; both are tributaries to the river.
The South Fork New River is classified by the State of North
Carolina as a Class C waterway. Class C waters are fresh waters
suitable for fish and wildlife propagation, agricultural uses,
secondary recreation (boating and wading), and uses requiring
waters of lower quality. The river is used as a secondary source
of supply by Boone's municipal water company, which routinely
tests the headwaters for fecal coliform bacteria. Boone also
tests the Winkler Creek tributary for chemical properties,
temperature, and turbidity. Test results for 1988 are shown in
Table 3.12.
The Boone municipal wastewater treatment plant discharges
effluent into the South Fork New River 0.5 mile upstream of the
US 421 river crossing. Biochemical oxygen demand (BOD) in the
river is recorded upstream and downstream from the.plant. Test
results for July and August 1988 are shown in Table 3.12.

On-site observations for pollution were conducted of streamflows
and their physical parameters within the study area. Readily
observable indications of pollution include odor, bubbles, oil
slicks, unusual color, siltation, and bed loading. Signs of
pollution were observed only in Hardin Creek at US 421; although
stream flow was clear, surface bubbles and an organic odor were
detected. Areas drained by the creek include a shopping center,
commercial properties along US 421, and the Boone Lumber Company.
Both the South Fork New River and the stream that enters it just
south of US 421 were observed to be clear, with little siltation
of the stream beds and no indication of pollution.
As shown in Table 3.12, levels of turbidity increase
significantly after a rainfall event. Turbidity refers to the
cloudiness of the water and, in the study area, is largely
dependent on runoff conditions as material is added to the water
from vegetation, surface litter, soils, and rocks with which the
surface runoff of precipitation comes in contact. It is measured
in Jackson turbidity units (JTU), which are equivalent to the
interference to light transmission caused by 1 milligram per
liter (mg/1) of a standard suspension. Turbidity restricts the
penetration of sunlight through water, thus decreasing plant
photosynthesis, and can also impair respiration in fish.
Ground Water - Ground water is found below the water table where
all openings in the soil or rock are completely filled with
water. The water table in the study area is usually found at
3-26
depths less than 40 feet in the saprolite overlying the fractured
bedrock.9 In the lowlands, ground water may be encountered at
depths between 5 and 20 feet. The base flow in streams and
creeks in the study area is from ground water discharge, which
occurs where elevations of the water table lie above the soil
surface.l� In the bedrock below the water table, water fills the
network of interconnected fractures. An idealized geophysical
cross section showing ground water storage is depicted in Exhibit
3.5.
The fractured character of the bedrock is conducive to the
existence of a water table or unconfined aquifer. Ground water
contained in water table aquifers is recharged (replenished)
locally mainly from precipitation infiltrating the overlying
soils.11 Ground water recharge in this area is shunted laterally
through fractures in the rocks to points of discharge less than 1
mile (commonly less than 0.5 mile) from their point of arrival at
the water table.12
Most domestic water supplies outside Boone's town limits come
from drilled wells, which draw water from fractures in the
bedrock. These fractures diminish in size and number with depth
so that drilling wells deeper than 300 feet will not
substantially increase well yields.13 An estimated fifty to
sixty wells and one spring lie within the study area. The wells
range from 100 to 200 feet in depth and intersect the water table
at an average depth of 40 feet.
3-27
3.6.4 Floodways and Flood Plains
The floodway width and boundaries are as indicated by the Federal
Emergency Management Agency (FEMA) and by Boone's municipal
planning department's Flood Boundary and Floodway Map. One
ingression of right-of-way within a 100-year flood boundary was
identified and is shown on Exhibit 3.6. The affected area is
adjacent to the existing crossing of Hardin Creek by US 421 and
is common to all alternative alignments.
3.6.5 Hydrology and Drainage
The study area is located within the watershed of the South Fork
New River. The drainage area of the watershed above the bridge
on US 421 is 34.8 square miles.14 Drainage patterns are closely
related to topographic relief. Stream channels are well defined
and carry significant flows following normal precipitation.
During dry periods, they may carry a base flow of discharging
ground water or have dry bottoms.
The western section of�the study area is drained by Hardin Creek
to the South Fork New River. Present runoff conditions
frequently overload Hardin Creek, causing the creek to overflow
its stream bed and flood adjacent residences. The northeastern
section drains to the river via an unnamed stream. The remainder
of the study area drains directly to the South Fork New River,
which borders the area to the east and south.

3.6.6 Topography, Geology, and Soils
Topography - Watauga County lies within the Blue Ridge
physiographic province in the broadened inter-valley of the South
Fork New River drainage basin and is bordered by the river on the
east and south.15 The project area is generally characterized by
moderately rolling uplands with localized steep slopes. Small
areas of nearly flat terrain are present in the lower elevations
at the east and west boundaries.
Elevation averages approximately 3,200 feet above sea level. The
highest peak contiguous to the study area lies to the north and
rises 3,640 feet above sea level. The lowest point, located at
the westernmost portion of the study area, is at Elevaton 3150.
Geology - Land within the vicinity of the study area is underlain
by a layer of disintegrated (weathered) rock referred to as "sap-
rolite" or "residuum" and bedrock that is a lower unit of the
Grandfather Mountain Window geologic group.16 Well logs indicate
that saprolite depth varies from a few inches to approximately 50
feet. Positioned 2 to 3 miles north of the inactive Grandfather
Mountain fault line, the area's bedrock is broken in an intricate
network of fractures, as represented on Exhibit 3.5. The
dominant rock type is Cranberry granite gniess, which is
intermixed and interlaid with hornblende gneiss, mica gneiss, and
mica schist.l�
3-29
The Blue Ridge province is underlain by a complex assemblage of
metamorphic and igneous rock types. As a result of the variable
nature of lithologies within the province, compositions,
textures, and structural features of mineral assemblages are
heterogeneous and anisotropic. Boundary transitions between rock
types are generally not well defined.l$ A geologic map of the
region is shown on Exhibit 3.7. There are no known major active
faults within the province, and the seismic activity of the study
area is low.
Soils - Soils in the study corridors for US Route 421 between
Boone and the South Fork New River have been mapped into six soil
series: Halewood, Porters, Perkinsville, Tusquitee, Hatboro, and
Chewacla.l9
The Halewood series is the most prevalent and comprises approxi-
mately 40 percent of the study area. These soils are found on
the tops and sides of mountains, ridges, and hills at elevations
up to 4000 feet. They are residuum of'granite and low micaceous�
acid schist and gneiss. Halewood soils are classified as
moderately drained, moderately permeable, strongly acidic, and
with medium to high surface runoff. Erosion potential is
moderate if unprotected.
Porters series soils represent approximately 60 percent of the
study area north of US 421 and 10 percent of that area south of
US 421. Porters soils are residuum of the same weathered, low
3-30
micaceous igneous and metamorphic rocks as the Halewood series,
and to some extent hornblende gneiss, hornblende schist, diorite,
and metadiabase.
Characteristics of Porters and Halewood soils are very similar,
mainly differing in the more friable medium-texture of the
Porters' subsoil. Due to this very friable subsoil, which has a
high capacity for absorbing water, Porters soils are less
erodible. Erodibility is slight to moderate for unprotected
slopes with less than 30 percent grade.
An estimated 45 percent of the area south of US 421 consists of
soils from the Perkinsville series. These soils are derived by
disintegration of the same bedrock as the Halewood series and
differ mainly in color, being more yellow. The surface soil
contains some rock fragments (mostly quartz), and the subsoil
contains a few partly decayed rock fragments up to 2 inches in
diameter. Perkinsville soils are moderately erodible when not
protected by vegetation or other means of erosion control.
Tusquitee soils are present in two small areas traversed by all
corridors� These colluvial soils occur adjacent to areas of
Porters and Halewood soils on the foot slopes of mountains and
hills, from which they have washed. They are moderately well
drained and have medium to� strong natural acidity. Surface
runoff is medium to low, with a slight hazard of erosion on
steeper, unprotected slopes.
3-31
Hatboro loam is found in the stream bottoms of Hardin Creek and
its feeder branches. Formed from young alluvial material, its
texture ranges from loam through loamy fine sand to gravel, and
its organic matter content is medium to low. Surface runoff is
low, with slow internal drainage.
A stream bed roughly paralleling the existing US 421 highway west
from the South Fork New River consists of Chewacla loam.
Occurring on nearly level alluvial flood plains, this soil
consists of material originating chiefly from gneiss, schist, and
granite. Surface runoff and internal drainage are slow.
Substratum may consist of sand, gravel, or cobbles. Above the
water table, permeability is moderate to moderately rapid.
3.6.7 Hazardous Waste
Disruption of hazardous waste sites during roadway construction
could have a detrimental effect on surface water, ground water,
soils, vegetation, wildlife, human health, and human welfare.
Hazardous waste is generally defined as any waste material that
has or, when combined with other materials, will have a dele-
terious effect on people or the environment. Characterized as
either reactive, toxic, infectious, flammable, explosive,
corrosive, or radioactive, hazardous wastes may be solids,
sludges, liquids, or gases. Potential hazardous waste sites
include landfills, dumps,
storage tanks.
pits, lagoons, salvage areas, and
3-32
,
�I
' The following sources were used to identify potential hazardous
' waste sites within the study area:
- Field inspection and evaluation of existing land use.
' - Aerial photographs and topographic maps.
' - Local representatives of agencies responsible for pollution
control, hazardous material regulation, and public safety.
, - Records of state and, local agencies regarding hazardous
material use and disposal.
' - Government publications of known hazardous waste sites.
, North Carolina's hazardous waste management program is primarily
directed by the state's Department of Human Resources (DHR),
' Division of Health Services - Solid and Hazardous Waste Manage-
' ment Branch. Other agencies consulted in the identification
process were the Town of Boone's public utilities and fire
� departments and a local waste management company.
' One known and three potential hazardous waste sites are located
within the study area. The name, address, and a brief
' description of each are given in Table 3.13; Exhibit 3.8 shows
the locations of the sites. All are sites of storage tanks for
�petroleum products. Underground and aboveground tanks used for
' petroleum product storage are not generally considered signifi-
cant hazardous waste sites; however, hydrocarbon contamination of
' soil and ground water can result from leakage or spills at these
locations.

' This survey of potential hazardous waste sites within the study
, area may not be all-inclusive. Pre-existing and illegal dump
sites may be undocumented and lack surficial evidence to
' determine their existence. Any additional hazardous waste sites
identified during the public and agency review process will be
' considered in the selection of recommended alternatives and
, incorporated in the Final EIS.
3.7 NATURAL RESOURCES
r
The flora and fauna study was conducted by an ecological team
' using records search, field review, and determination of land use
using aerial photographs. The team's inventory of natural
' systems is included in the report US Route 421 Flora and Fauna
' Inventory and General Overview appended by reference.20 The
following is a report summarization.
'
' 3.7.1 Flora Survey
' The vegetation within the proposed project area is a mixture of
three general types: urban plantings, pasture land and open
, fields, and small secondary growth forests. The secondary growth
forests are composed of agricultural coniferous plantings, pine
' forests of various ages, and mixed hardwood stands of varying
' composition and age. There are no tracts of virgin woodland or
wetland in the project area. Floral species that are endangered,
' threatened, or that deserve special attention were not
encountered.
'
' 3-35
3.7.2 Fauna Survey
Much of the project area has been disturbed by man's activities;
however, the biological requirements necessary to sustain
wildlife populations (food, shelter, and water) are available.
The Eastern chipmunk (Tamias striatus) and the cottontail rabbit
(Sylvilagus floridenus) were observed in the area. Other
mammalian species reported to be in the area, including big game
species, were not observed. Avian species observed were the
common crow (Corvus brachyrhynchos), mockingbird (Mimus
polyglottis), field sparrow (Spizella pusilla), cardinal
(Richmondea cardinalis), robin (Turdus migratorius), and turtle
dove (Zanaidura macroura). Other non-game birds were heard, but
were not observed.
None of the reptiles or amphibians believed to exist in the
Pisgah National Forest, or its immediate environs, was observed
in the project area. A field study of fish in the South Fork New
River was n,ot conducted for this study. However, in prior
studies conducted on the New River and its tributaries, 3
species of trout, 16 species of minnow, 2 species of suckers, 5
species of sunfish, 4 species of darters, and 2 species of
sculpin were identified. None of these species are considered
endangered, threatened, or of spe.cial concern; however, all
efforts should be made to maintain undisturbed the
state-supported fishery of Ambloplites rupestris and Micropterus
dolomieui that exists in the South Fork New River.
3-36
3.7.3 Wetlands
Wetlands are important natural resources that benefit the total
physical environment. Potential functions of wetlands include
habitat for wildlife, recharge areas for ground water, inter-
ception and mineralization of organic runoff, hydraulic baffling
and mediation of downstream currents, and sedimentation of
turbidity in runoff waters.
The definition of wetlands is given in Executive Order 11991,
Section 7(c):
The term "wetlands" means those areas that are
inundated by surface or ground water with a frequency
sufficient to support and under normal circumstances
does or would support a prevalence of vegetative or
aquatic life that requires saturated or seasonally
saturated soil conditions for growth and reproduction.
Wetlands generally include swamps, marshes, bogs, and
similar areas such as sloughs, potholes, wet meadows,
river overflows, mud flats, and natural ponds.
The DNRCD has classified wetlands as areas having hydric or
� predominantly hydric soils. Hatboro loam and Kinkora loam are
1 classified as hydric �soils. Hatboro loam is conjunctive to
Hardin Creek at the western edge of the project corridor;
, however, this area is in commercial use. Alternative B crosses
an area of Kinkora loam less than 1 acre in size, which is
� presently in residential use. Other potential wetlands areas are
� adjacent to the South Fork New River; however, these areas have
been converted to row cropping and pasture land.

3-37
3.7.4 Prime and Important Farmlands
Prime and important farmlands are identified by the following
soil types provided by the Watauga County Soil and Water
Conservation Service of the USDA: Evard .(formerly Halewood),
Porters, Ineyville (formerly Perkinsville), Tusquitee, and
Kinkora.21 Exhibit 3.9 shows portions of the study area
representative of these soils. Most of the study area is
classified by soil type as prime or important farmland; however,
existing urban, commercial, and industrial development of the
area precludes agricultural use. Current agricultural production
is limited to Christmas tree farming on the hills south of US
421.
3.7.5 Wild and Scenic Rivers
Wild river areas are defined as "rivers or sections of rivers
that are free of impoundments, and generally inaccessible except
by trail, with watersheds or shorelines essentially primitive and
unpolluted." Scenic river areas are defined as "rivers or
sections of rivers that are free of impoundments, with shorelines
or watersheds still largely primitive and shorelines largely
undeveloped but accessible in places by roads." According to
officials at the DNRCD, there are no state or federally
designated wild and scenic rivers in Watauga County.

ENVIRONMENTAL CONSEQUENCES
�
Using information discussed in Section 3.2 and aerial photographs
' at a scale of 1 inch equals 200 feet, an approximation of the
number of acres by land use type required for each alternative's
' right-of-way was calculated and is shown in Table 4.1.

4.1.1 Economics
The improvement of US 421 will have the following economic
effects:
- Increase construction-related employment.
- Eliminate some property tax role lands.
- Alter property values.
- Reduce travel costs due to a safer and less congested
roadway.
' All of the alternatives will have a positive employment impact.
Construction costs for the improvement construction of US 421
' from NC 194 to just west of the South Fork New River ranges from
$2,603,000 to $4,553,000. Using a common multiplier of three
' times the initial construction cost, the improvement of US 421
' will contribute aetween $7.8 million and $13.6 million in
additional income over the life of the pro�ect.

Property values could increase or decrease. Residential
properties adjacent to the improved road that experience
increased noise levels or negative visual impacts will probably
decrease in value. Commercial and industrial properties adjacent
to the new roadway should rise in value, however, due to their
increased accessibility.
4.1.2 Relocations
Relocations and displacements will be necessary under all of the
alternatives; however, the estimated number of displacees is
different for each, as shown in Table 4.2. Alternative A should
result in the fewest family and business displacements, while the
other two alternatives will require about the same number of
displacees of both families and businesses. Alternative E will
have an estimated gravesite displacement of apporoximately 100.
A detailed Relocation Report is included in Appendix B.
The NCDOT has determined that adequate residential and business
property is available to relocate those displaced and offers
several programs designed to minimize the inconvenience of
relocation. Under the Relocation Assistance Program, experienced
NCDOT staff would provide displacees with information on
availability and cost of homes, apartments, and businesses for
sale, as well as financing and other housing programs. The
Relocation Moving Payments Program, in general, provides for
payment of actual moving expenses incurred during relocation.

Where displacement will force an owner or tenant to purchase or
rent property of higher cost or to lose a favorable financing
arrangement, the Relocation Replacement Housing Payments or Rent
Supplement Program will compensate owners who are eligible and
qualify up to $4,000.
When families cannot be relocated within their financial means,
and/or cost of replacement housing falls outside these limits,
the law provides for Last Resort Housing. This program allows
broad latitudes in methods of implementation by the state so that
safe, decent, and sanitary replacement housing can be provided.
It is not believed that this program will be necessary.
The gravesite relocations will be handled by officials with the
NCDOT staff. A search will be conducted to locate family members
of those buried in each gravesite and a suitable relocation will
be found.
4.2 CULTURAL RESOURCES
4.2.1 Schools
The only school close to any of the corridors, Hardin Fork
Elementary School, would not be impacted by any of the
alternatives.
4-5
4.2.2 Section 4(f) of the Department of Transportation Act
Section 4(f) is not required of an exclusively North Carolina
State funded project such as this. Regardless, none of the
alternatives will require the use of any park, wildlife refuge,
or recreational land as defined in Section 4(f) of the 1966 U.S.
Department of Transportation Act, as amended.
4.3 UTILITIES
4.3.1 Electric Power
All alternatives cross the transmission lines that run north-
south through the project area, and minimal impacts are expected.
Utility relocation is included in the costs estimated in Section
2.4.
4.3.2 Water and Sewer
All alternatives cross areas now served by both water and sewer
lines. Utility relocation is included in the costs estimated in
Section 2.4.
4.4 MINERAL RESOURCES
No existing mines or sites favorable for mining of any mineral
resource are known. If, however, an underground mine were
encountered during construction, a detailed survey and
investigation should be conducted to determine proper abandonment
techniques.
4-6
'
' 4.5 PHYSICAL ENVIRONMENT
' 4.5.1 Noise
, A preliminary noise analysis was conducted to determine existing
and anticipated noise levels and possible mitigation measures for
' sites exceeding the noise abat�ment criteria. This analysis
was conducted using the methodology outlined in Title 23 of the
' Code of Federal Regulations.l
' Noise Abatement Criteria - Noise abatement criteria guidelines
' are established by the FHWA and are shown in Table 4.3. These
levels represent the upper limits of acceptable noise conditions
' and are applicable to places of regular human activity, not to an
entire tract of land upon which a particular activity is based.
' Exceptions include areas where serenity and quiet are considered
' essential even though the areas may not be subject to frequent
human use. An area is said to be adversely affected if a
' predicted noise level is within 2 adjusted decibels (dBA) of the
criteria established in Table 4.3, or if the predicted noise
' impact is equal to or exceeds the existing noise level by 15 dBA.
' Existing Noise Levels - Noise measurements were taken at 12 sites
within the existing corridor using standard data collection
' techniques outlined by the FHWA.2 The sites chosen represent a
' mixture of rural, residential, and commercial areas. Exhibit 4.1
shows these noise monitoring locations.

The descrip�or selected for noise monitoring and a�alysis of
potential noise impacts is the hourly equivalent sound level
(Leq) that in one hour would contain the same acoustic energy as
the time-varying sound level during the same period. This
measurement of Leq is based on energy averaged, A-weighted
decibels of dBA. Measured noise levels ranged from 46.5 to 73
Leq, as shown in Table 4.4. The three highest Leq sites--30, 38,
and 52--are located along existing US 421. The quietest area
measured was Site 59, which is located far from any major
roadway.
Generalized Future Traffic Noise Levels - The impact of each
proposed alternative, as well as the No-Build Alternative, was
determined by comparing probable future traffic noise levels with
existing noise levels using approprxate FHWA noise abatement
criteria for receptors along each project. The computer program
STAMINA/OPTIMA 2.0 was used to predict future noise levels.3
This information is shown in Table 4.5.
' The 67- and 72-dBA noise level contour, which is established by
the FHWA as the maximum Leq value for residences an� commercial
' property, respectively, was determined for each alternative for
the design year. The predicted extent of the 67-dBA noise level
' contour for each alternative is approximately 155 feet from the
, roadway centerline. The predicted extent of the 72-dBA noise
level contour for each alternative is approximately 80 feet from
, the roadway centerline.

Noise Impact Analysis - The two major land uses most affected by
noise in Design Year 2008 are residential and commercial. As
shown in Table 4.5, each receptor is identified by land use
activity and compared to the noise abatement criteria established
for the different land use activities.
Those receptors that exceed their respective noise abatement
criteria are identified in Table 4.5. By Design Year 2008 under
a no-build scenario, approximately 29 receptors would experience
a noise level in excess of the noise abatement criteria, as shown
in Table 4.6. The majority of receptors that exceed the noise
abatement criteria for all of the construction alternatives would
a.lso exceed those criteria under the No-Build Alternative. In
some instances, there would even be a reduction in the predicted
noise levels under the construction alternatives.
The following preliminary evaluation of various noise abatement
measures was conducted with respect to the proposed alignment
alternatives using federal guidelines on noise abatement:
* Noise Barriers - The use of noise barriers appears to be
impractical at all locations for the following reasons:
- 90-foot right-of-way
- Partial access control
- Commercial sites lining US 421
- Impact on site distance, drainage, access, and future
development.
However, once the final alignment is chosen, the use of noise
barriers will be reexamined.

* Acquisition and Relocation - Acquisition (fee simple or
easement) and relocation in impacted areas for noise abatement
shall be examined after the selection of the recommended
alignment. Roadway alignment development is planned to
prevent or minimize the necessity of these actions.
* Land Use Controls - One of the most effective noise abate-
ment measures is proper land use controls. Once an alignment
is selected, local jurisdictions should limit the growth of
noise-sensitive land uses adjacent to the proposed roadway
using setback requirements, building codes, and zoning.
4.5.2 Air Quality
An air quality assessment was made to determine the air emissions
associated with existing US 421 and/or improvements. Motor
vehicles are known to emit CO, NO, hydrocarbons (HC), TSP, 502,
and Pb (listed in order of decreasing emission rate). Different
assessment procedures are required for each of these pollutants.
Carbon Monoxide - Two concentration components make up the CO
levels: background and local. The background component is due
to CO emissions from cars on other streets or other sources. The
local component is due to CO emissions from automobiles on the
study highway. In the absence of site-specific or recent actual
measurement of background CO, default CO concentrations were used
as directed by officials at the DNRCD. These background CO
values were added to the calculated local one-hour and eight-hour

CO results. The one-hour and eight-hour background CO
conceritrations used are 2.0 parts per million (ppm) and 1.5 ppm,
respectively.
An indirect source analysis was used to calculate local CO
concentrations. This analysis was conducted first on the worst-
case scenario, the location that has the highest traffic volumes
for all of the alternatives. The premise of this approach is
that local CO concentrations elsewhere along the project corridor
will be lower when compared to this potential worst-case
scenario. The indirect source analysis was performed in
accordance with guidelines issued by the DNRCD.4 The analysis
was conducted at the locations of highest estimated average daily
traffic under both no-build and construction scenarios for Design
Year 2008.
Receptors of CO concentrations were taken at the rights-of-way
boundaries. Two receptors at each side of the right-of-way,
which is 45 feet from the center of the road, were used as
measurements for the alternative construction corridors. The
No-Build Alt2rnative's two receptors were located at the existing
rights-of-way, which are 50 feet on each side of the centerline
of the existing road. The dispersion of CO for both the no-build
and alternative construction corridors was simulated using the
FHWA CALINE4 line source dispersion model.5 Input parameters
provided by officials at the DNRCD are summarized in Table 4.7.

Motor vehicle emission rates were computed using the MOBILE3
emissions model developed by the U.S. EPA.6 Input parameters
received from officials at the DNRCD are also shown in Table 4.7.
The analysis was conducted under simulated worst-case
meteorological condition, including low wind speed, stable
non-mixing atmosphere, and low ambient temperature.
The computer simulation of future traffic and meteorological
conditions was conducted for peak one-hour conditions. To
account for the variation in traffic and meteorological
conditions over time, a persistence factor was used to convert
the worst-case, one-hour resul�ts to the corresponding worst-case,
eight-hour results. A one-hour to eight-hour persistence factor
of 0.75 was used for this purpose as dictated by the DNRCD.
Table 4.8 presents the one-hour CO concentration results of the
worst-case scenario for both the no-build and construction
alternative alignment corridors. As shown in Table 4.8, neither
the no-build nor the alternative alignment corridors' highest
one-hour CO concentration exceeds the AAQS for CO (35 ppm), as
shown on Table 3.11. Thus, based on these data, neither the
one-hour nor eight-hour AAQS is likely to be exceeded at any
point along any of the corridors throughout the design year.
Hydrocarbons and Nitrogen Oxides - Automobiles are generally
regarded as significant sources of HC and N0. HC and NO emitted
from cars are carried into the atmosphere where they react with
sunlight to form 03 and NO2. It is the resulting 03 and NO2 that
are of concern.

Area-wide automotive emissions of HC and NO are expected to
decrease in the future due to the continued installation and
maintenance of pollution control devices on new cars. No
appreciable changes in area HC and NO automotive emissions are
expected with either the no-build or alternative alignment
corridors. Watauga County and the Town of Boone are unclassified
for 03 and NO2, but are considered to have a relatively low
concentration of both.
Particulate �9atter and Sulfur Dioxide - Automobiles are not
generally regarded as significant sources of TSP and S02.
Nationwide, highway sources account for less than seven percent
of TSP emissions and less than two percent of S02 emissions. TSP
and S02 emissions are predominantly the result of non-highway
sources (e.g., industrial, commercial, and agricultural). Air
quality standards for TSP and S02 are unclassified for Watauga
�County and the Town of Boone. Because emissions of TSP and S02
from cars are very low, there is no reason to suspect that
traffic on the No-Build or alternative alignment corridors will
cause air quality standards for TSP and S02 to be exceeded.
' Lead - Automobiles emit lead as a result of burning gasoline
containing tetraethyl lead, which is added by refineries to
' increase the octane rating of the fuel. New cars with catalytic
Iconverters burn unleaded gasoline, eliminating lead emissions.
Also, the U.S. EPA has required the reduction in the lead content
,
�
4-19
�
of leaded gasolines. The overall average lead content of
gasoline in 1974 was 2 grams per gallon and is expected to be
0.05 gram per gallon by 1990.
Air quality standards for lead are unclassified in Watauga County
and the Town of Boone. In the future, lead emissions are
expected to decrease as more cars use unleaded fuels and as the
lead content of leaded gasoline is reduced. Therefore, it is not
expected that traffic on the no-build or alternative alignment
corridors will cause the AAQS for lead to be exceeded.
4.5.3 Water Quality
Surface Water - Impacts to surface water quality associated with
this project would result from suspended solids and dissolved
minerals transported by storm runoff from the completed project
and possible erosion and sedimentation during construction (see
Section 4.9.1). Suspended solids cause turbidity in surface
waters and sedimentation in stream beds. The risk of potential
impact varies directly with the following:
- Depth of right-of-way cuts.
- Surface area of cut and fill slopes.
- Steepness of slopes.
- Erodibility of soil type.
- Proximity of affected areas to surface waters.
- Increase in paved surface.area.

Alternative E would require the least increase in impervious
(paved) surface area. Alternative A would require a lesser
increase than Alternative B. Although none of the soil types in
the study area is highly erodible, erodibility of soil types
encountered in the eastern half of the study area differs with
right-of-way alignment. The Porters series soils, associated
mainly with Alternatives A and E, are less erodible than the
Perkinsville series, the soil type mainly associated with
Alternative B.
Saprolite, which underlies l,and in the study area, is less
leached at increased depths; therefore, saprolite e.xposed in cut
sections will contain a higher percentage of soluble materials
than surface soils. Runoff passing through freshly exposed
saprolite will have increased dissolved solids concentrations.
This impact will not be significant as the rock group underlying
the study area is not highly soluble and yields a soft, slightly
acidic ground water with low concentrations of dissolved
constituents.�
Stringent erosion control measures are mandated by the FHWA and
the North Carolina Sedimentation Pollution Control Act of 1973.
The law requires that an erosion and sedimentation control plan
be approved before land-disturbing activities begin. The plan
must include temporary and permanent control measures to prevent
accelerated erosion and off-site sedimentation. These control
measures must ',� designed to provide protection from a rainfall
4-21
event the magnitude of the 10-year storm (5Z inches of rain in a
24-hour period). Specific requirements of the law limit the
angle of cut and fill slopes, restrict runoff velocities, and
specify that permanent ground cover sufficient to prevent erosion
be provided.
Where design constraints allow, grass medians with swales may be
used as drainage areas. These would provide detention of runoff
and promote infiltration. If necessary, detention ponds,
excavated sediment traps, or vegetative filters could be used to
prevent degradation of the present water quality. With proper
implementation of these pollution control measures, storm runoff
from the completed project is not anticipated to have a
significant impact on the quality of surface water in the area.
Ground Water - The probability that any given alignment will
affect the existing ground water ecosystem is relative to the
depth of its cut sections. Ground water tables in the vicinity
of deep roadway cut sections may be lowered. with a maximum cut
of 20 feet, Alternative E is not anticipated to have a
significant impact on ground water elevation. The approximate
40-foot cut section in Alternative A may result in a slight
lowering of the water table. Alternative B, requiring
approximately an 80-foot cut section, would be the most likely to
adversely affect shallow wells close to the project.

Any effect on domestic water supply could be mitigated by the
availability of municipal water service. A 16-inch water main
from Boone currently crosses Alternative A to serve the
industrial park. Water lines also extend approximately 1,000
feet east beyond Boone's town limits on US 421. Tentative plans
for future expansion include extension of a 16-inch water main
along US 421 to Bamboo Road, east of the South Fork New River.
4.5.4 Floodways and Flood Plains
One ingression of right-of-way within the 100-year flood boundary
has been identified; however, with proper drainage design, the
impact will be minimal. The only regulatory floodway crossing
will be at Hardin Creek, which is presently crossed by US 421 at
the same location. Final design of, the culvert structure must
ensure that the floodway will carry the 100-year flood without
increasing the water surface elevation by more than 1 foot at any
point.
�
'
�
�J
,
�
�
�
4.5.5 Hydrology and Drainage
One major stream, Hardin Creek, and one unnamed stream of lesser
significance are unavoidably crossed by all alignments. At each
hydrologic crossing, natural drainage patterns will be maintained
and culvert structures used. Final design will ensure. that
restriction of stream flow through these structures will not
cause significant increases in flooding.
4-23
Discharge rates are anticipated to increase due to higher per-
centages of impervious areas; however, any increase in flow rates
will be attenuated by use of detention areas. Detention areas
promote sedimentation of solids in addition to reduction of peak
flows. Such an area may be necessary for discharge to Hardin
Creek, as residents downstream frequently report flooding from
present flows. Stream crossings and modifications will require
permits from the U.S. Army Corps of Engineers (USACOE) and the
North Carolina DNRCD.
4.5.6 Topography, Geology, and Soils
The effect of the project on the study area's topography,
geology, and soils varies with the amount of earthwork necessary
for each of the alternative alignments. The greatest amount of
earthwork is required by Alternative B and the least amount by
Alternative E. Soil properties are common to all alternative
alignments. Their non-cohesive and friable nature limits the
angle of slopes and requires proper roadway design.
Blasting for rock excavation may be required with Alternative B.
Damage to adjacent properties from ground vibrations, tlyrock,
and air pressure waves can be minimized by use of proper blasting
procedures.
4.5.7. Hazardous Waste or Petroleum Storage Tanks
The following hazardous waste or petroleum storage tank sites
have been identified within the proposed right-of-way of the
alternatives.
4-24
,
�
e
�
�
'
�
�
'
�
�
Alternative E- One identified and three potential hazardous
waste sites are located close to the existing US 421 alignment.
The known site is:
l. A previous gasoline service station, known as Fire Lines,
on the northwest corner of US 421 and Grove Street.
The potential sites are:
l.
��
Two gasoline service stations, Servco and Wilco, adjacent
to and north of US 421, east of Highway 194.
The aboveground storage tanks of the Appalachian Oil Company
approximately 150 feet south of US 421 at SR 1596.
The site of the converted service station at US 421 and Grove
Street contains an underground storage tank and has been listed
for remedial action funding from the North Carolina Leaking
Underground Storage Tank (LUST) trust fund. At this time no
schedule has been established for this funding action.
' Alternative A- The two-service stations on existing US 421 east
of NC 194 and the converted service station at US 421 and Grove
� Street are likely to be affected by this alignment. No
additional sites in the vicinity of the northern alignment have
obeen identified.
'
iJ
�
�
Alternative B- Potential hazardous waste sites associated with
the southern alignment include the service station at the inter-
section of US 421/NC 194 and an underground petroleum storage
4-25
tank, formerly used by the Coca-Cola distributor at the present
location of Anchor Supply Company. The latter is close to the
centerline of the proposed southern alignment. The hazardous
waste site presently under assessment on US 421 at Grove Street
is also common to this alignment.
Conclusion
Following alternative alignment selection and during right-of-way
plan stage, the extent of disruption to the identified potential
hazardous waste sites for the proposed highway construction will
be determined. A site assessment will be performed (if
necessary) to determine levels of contamination and evaluate
corrective measures along with the necessary costs. Resolution
of problems associated with hazardous materials will be
coordinated with regulatory agencies.
4.6 NATURAL RESOURCES
4.6.1 Flora and Fauna
The proposed project will result in some negative impacts to
habitats within the alternative corridors. Although a signifi-
cant amount of the surface area is composed of urban setting,
loss of open area and field�and forest cover will reduce habitat
for all animal species. There are no endangered, threatened, or
special-concern plants in the area, but loss of older tree
specimens subtracts from the seed source for future generations.
This in turn reduces those biological factors required by all
animal species. Biological impacts to be expected from
vegetation removal within highway right-of-way include:
4-26
- Habitat modification from destruction of flora and fauna.
- Loss of biological productivity in affected areas.
- Imposition of physical barriers resulting in increased road
kills.
- Decreased percolation due to loss of biological surface
area.
- Increased surface runoff and erosion potential.
Using aerial photographs and field measurements, the approximate
acreage of wildlife habitat loss for each alternative corridor's
right-of-way is estimated as shown in Table 4.9.
Immediate, short-term impacts will result from the removal of
vegetation and the rearrangement of the topical geography to
accommodate new road cuts and roadbeds. Therefore, construction
work areas should be restricted where practical, and proper
precautions should be taken to limit erosion to the immediate
work area.
,
Long-term impacts can be diminished by the use of selected
� plantings as replacement of flora along highway rights-of-way.
' Rapidly growing indigenous species with good ground cover, varied
understory, and varied crown cover will provide ample food and
' natural cover for the indigenous wildlife during all seasons of
the year. Secondary succession will eventually replace unwise
1 selection of floral species.

�A major environmental impact will be the encroachment upon the
South Fork New River in connection with relocation and expansion
of the US 421 bridge. Strict adherence to erosion control
standards must be a primary concern in this area. There are no
known endangered, threatened, or special-concern species within
the immediate construction area of the South Fork New River;
however, any disturbance to this aquatic habitat will have
repercussions for a significant distance downstream.
An increased BOD load could result from disturbance to, and
distribution of, bottom or bank organic materials accumulated
through time and natural processes. This in turn may affect the
dissolved oxygen levels available to the immediate downstream
fauna. Increased siltation resulting from improperly controlled
erosion within the project area will definitely adversely impact
all gill-respiring species, both in the immediate area and for a
significant distance downstream. Displacement of bottom-dwelling
species is bound to occur as a short-term impact that will be
mitigated through natural stream succession. Stream bank impacts
resulting from vegetation removal can be resolved with
replacement plantings of the appropriate indigenous species.
4.6.2 Threatened or Endangered Species
Review of Federally Listed Species - Consultation with the U.S.
Fish and Wildlife Service indicates that two threatened plant
species and one threatened avian species may occur in the project
!��%7
area, although the agency gave no indication of the locations of
critical habitats. The species at issue are Heller's blazing
star, Liatris helleri; the Blue Ridge goldenrod, Solidago
spithamaee; and the American peregrine falcon, Falco peregrinus
anatum. The following Status Review species may also occur in
the project area: New England cottontail, Sylvilagus
transitionalis; hellbender, Cryptobranchus alleganiensis; bog
turtle, Clemmys muhlenbergi; Kanawha minnow, Phenacobius
teretulus; bent avens, Geum geniculatum; spreading avens, Geum
radiarum; white-leaved sunflower, Helianthus glaucophyllus;
Gray's lilly, Lilium grayi; and Gray's saxifrage, Saxafraga
carolinana. Other species listed for the State of North Carolina
are not critical to the area of study.8
Review of State Listed Species - There is no official listing for
the State of North Carolina, instead the state agencies use the
federal lists. However, the North Carolina Natural Heritage
Program has listed two plant species for special concern that may
occur in the area of study: the wild mock cucumber, Echinocystis
labata, and the crested shield fern, Dryopteris cristata.9
4.6.3 Prime and Important Farmlands
Land currently available for agricultural use that would be taken
for project construction was inventoried for each alignment.
Table 4.10 shows the approximate acreage required for each
alternative.

4.7 VISUAL IMPACTS
The construction of a new roadway or the upgrading of an existing
road to additional lanes will have some visual impact on adjacent
areas. It is necessary to provide adequate right-of-way that
complies with required design criteria while disrupting the areas
surrounding the right-of-way to the minimum extent possible. The
issue is further complicated by the steep terrain and related
limitations on construction in a mountainous area where it will
be necessary to cut into mountain sides while filling other
areas. Ridges and slope support will also be involved. This
activity will create visual barriers and, should the design not
receive proper attention, visual degradation. Therefore, it is
important that the areas where cut/fill/bridges are required be
studied, designed, and detailed to ensure an aesthetically
acceptable visual quality. '
Visual impacts would be greatest along Alternative B because it
would require the greatest cut at its eastern terminus. The
other alternatives, with proper landscaping, should have minimal
visual impacts.
4.8 ENERGY
Construction of any of the improvement alternatives will consume
energy; however, in the long-term, total energy utilization is
expected to be reduced dramatically over the No-Build Alternative
due to decreased vehicle delays and more efficient reliable
operating speeds.
4-32
�
�
�
4.9 CONSTRUCTION IMPACTS
4.9.1 Water Quality
' Water quality may be temporarily affected by construction activi-
ties at stream crossings and by erosion of unprotected slopes.
' The North Carolina Sedimentation Pollution Control Act of 1973
prohibits visible off-site sedimentation from construction sites.
' The law requires implementation of an approved plan, which
' includes temporary control measures for compliance. Erosion and
sediment control measures that may be used to minimize
� construction-related impacts are described in Federal Aid Highway
Program Manual (FHPM) 6-7-3 and by the North Carolina DNRCD.10
, Those measures include scheduling construction activities to
' minimize the extent and duration of erosion hazards and use of
temporary vegetation, mulching, sodding, sediment catch basins,
' silt fences, and diversion berms. Erosion control measures will
be retained as permanent roadway design features whenever
� possible.
�
�
�
�
�
�
�
4.9.2 Air Quality
Particulate matter or dust caused by heavy construction equipment
and denuded earth can have an impact on local air quality, as can
smoke caused by burning of cleared debris. Some measures to
control air quality impacts from construction include:
4-33
- Implementation of sound erosion control measures to ensure
that denuded earth is promptly covered with stabilizing
material such as grass, mulch, or asphalt.
- Covering of haul trucks.
- Use of water as a dust controller.
- Minimization of actual denuded areas.
- Strict control of construction burning.
CO and other pollutants contributed by automobiles may increase
during construction due to resulting traffic delays. If proper
traffic control measures are implemented, this should not be a
significant problem.
4.9.3 Noise and Vibration
Construction noise and vibration can be reduced through the
development of a construction noise plan limiting the use of
certain heavy vehicles during non-traditional work hours and days
and enforcing the presence of properly working mufflers on
construction equipment. Due to the urban setting in which this
project is located, the use of blasting materials should be
restricted.
4.10 IRREVERSIBLE AND IRRETRIEVABLE COMMITMENTS OF RESOURCES
The construction of the preferred alternative of US 421 would
require the following irreversible and irretrievable commitments
of resources:
4-34
'
S- Use of land within the right-of-way exclusively for trans-
� portation.
- Possible encroachment on the biotic communities.
O- Noise from construction and actual use of alternative
corridor for nearby properties.
' - Commitment of manpower and resources for construction.
'
'
'
�
'
,
�
�
'
�
e
'
�
'
However, a long-term savings in resources, particularly fuel and
amount of motorist time spent traveling, would be realized due to
the more efficient roadway. This roadway improvement would also
enhance long-term access opportunities and support the local and
regional commitment to encourage the growth and economic
viability of the Boone-Watauga County area. Thus, the commitcnent
of resources to the building of the roadway will be exceeded by
the savings in resources over time.
4.11 RELATIONSHIP BETWEEN SHORT-TERM IMPACTS AND LONG-TERM
BENEFITS
The short-term impacts would be limited to the actual
construction of the roadway. During this time, traffic would be
affected by temporary construction detours. Noise and vibrations
from heavy construction equipment will be noticeable, especially
from sites adjacent to the roadway corridor. Particulate matter
and air quality impacts could be a short-term by-product of the
construction. With a proper construction noise plan and erosion
control measures these impacts will be minimized.
4-35
Existing homes and businesses will be displaced due to right-of-
way requirements of the roadway. However, an analysis of the
area showed that there are adequate replacement housing and
business relocation opportunities. Even those workers in any
businesses that are relocated should be able to retain their work
but at the new locations.
Water quality could be adversely affected on the short term.
During construction, turbidity would be anticipated to increase
in the small creeks that all of the alternatives pass through.
This turbidity would also increase in the South Fork New River,
into which these creeks feed. However, through the use of water
quality control and erosion control measures, water quality would
return to preconstruction levels.
Construction of the preferred alternative improvement of US 421
would in the long term stimulate economic growth, save fuel and
travel time, and reduce accidents.

6.2 PUBLIC INVOLVEMENT
A comprehensive public involvement program was established to
inform and gather information from the public.
6.2.1 Computerized Mailing List
All individuals and organizations on the existing NCDOT mailing
list, as well as those that were collected or that requested to
be added to the mailing list, were placed in computer memory.
This mailing list was used to send newsletters and correspondence
concerning this Draft EIS. The names of approximately 90
individuals and organizations were collected.
6.2.2 Newsletters
Two newsletters were prepared for this Draft EIS and sent out in
February and April of 1989. Individuals on the computerized
mailing list and local public officials received each of these
newsletters, which are shown in Appendix B. The newsletters
present information on the progress of the study as well as maps
displaying alternatives under consideration. An additional
newsletter will be prepared after submittal of the Draft EIS.
6.2.3 Toll-Free Hotline Phone Contact
A toll-free phone number was established to make direct contact
available for those individuals and organizations with questions
C:�'�
or comments. The Project Engineer and Project Manager from
Hensley-Schmidt, Inc., were available at all times to answer the
phone. Approximately 100 phone contacts were made through the
toll-free phone number.
6.2.4 Small Group or Individual Informational Meetings
Staff was available throughout the study process to meet with
individuals and organizations on a one-to-one basis at the study
area to answer questions. Several landowners in the study area
took advantage of this opportunity.
6.2.5 Public Meetings/Worksho s
Two public meetings/workshops were held at the Town of Boone
Council Chambers on January 17 and May 18, 1989. Approximately
100 people attended the January 17 meeting, where officials from
the NCDOT and Hensley-Schmidt, Inc., made a formal presentation,

Description
Very low delay. Most vehicles do
not stop at all.
Still desirable with more vehicles
than LOS A stopping.
Individual cycle failures may begin
to appear but intersection still
operates at a desired level.
The influence of congestion becomes
more noticeable.
The limit of acceptable delay is
reached with poor progression and
frequent occurances of individual
cycle failures.
Unacceptable delay with severe
queuing occurring.

Watauga County
We have received notification from the State Clearinghouse concerning
the above project.
One archaeological site, 31Wt13, is located within the project area.
However, the site has not been evaluated for significance nor has a
systematic survey been conducted within the project.area to identify
additional significant archaeological resources. We recommend that a
comprehensive archaeological survey be conducted if Alternate B is
selected. If Alternate A is selected, a survey is recommended for the
eastern end only.
We understand that HensleySchmidt, Inc., the project consultant, will
conduct a cultural resources survey to identify and evaluate signif icant
historic and prehistoric resources. Since a historic structures survey
of Watauga County is currently under way, we sugoest that the project
consultant contact Deborah Thompson, Center for Appalachian Studies,
Appalachian State University, at 704/262-4089 (Tuesday or Thursday only)
for information on any structures surveyed within the area of potential
environmental effect. Our office looks forward to reviewing the survey
results in the near future.
The above comments are made pursuant to Section 106 of the National
Historic Preservation Act of 1966, the Advisory Council on Historic
Preservation's Regulations for Compliance with Section 106, codif ied at
36 CFR Part 800, and to Executive Order 11593, "Protection and Enhance-
ment of the Cultural Environment."

DATE:

SUBJECT: US 421 from NC 194 in Boone to West of the
South Fork New River, State Work Order No.
6.751008 (R-529 A), Watauga County, N.C.
The Wildlife Resources Commission's biological field
staff has reviewed the scoping letter on the proposed road
project and can not make specific recommendations until
final plans are presented for each proposed alternative
route. However, in order to minimize impacts to the
environment and wildlife habitats, we recommend that serious
consideration be given to the alternative to improve the
existing highway 421 roadway.
Since the proposed project and alternatives will occur
� in an area of urban development, we feel that an EIS
addressing wildlife, wetlands and stream habitats will not
be needed. We agree that impacts to streams and wetlands
� will be minimal because the project will not cross these
types of habitats. No endangered species .are known to exist
in this project area.
' To pr�vent off-site damage to the South Fork New River
located at the eastern edge of the project, standard DOT
erosion control guidelines should be utilizeci. Erosion
' controls should be designed to withstand a 10 year storm (5
1/2 inches of rain in 24 hour period) as required by the
St�tes' Sedimentation Act. When planning establish�ent of
new vegetation, consideration should be given to utilizing
' some planting materials with greater benefits to wildlife.
Adding white dutch or ladino clover to fescue and sericea
lespedeza plantings will increase benefits to many wildife
' species. Some plots of shrub lespedeza would meet erosion

Proposed Combined State EIS/Corridor location Report on
Proposed US 421 Improvements from NC 194 in Boone to
West of the South Fork New River in Watauga County
Project � 89-0696
Due Date March 6, I989
To better determine the impact, if any, to forestry and greenways
in the area of the proposed project, the combined Environmental
Zmpact Statement/Corridor� location report should contain the
following information concerning the-proposed.alternative routes
for the possible right—of—way purchases for the project:
1. The number of total woodland ac.res that would be taken out
of timber production and greenways as a result of new
right—of—way purchases.
2. The acres kreakdown of this Woodland concerning present
conditions such as clearcut areas, young growning timber,
and fully stocked stands of very productive timber within
the new right—of—way purchases for disturbed and undisturbed
portions.
3. The site indexes of the forest soils that would be involved
within the proposed right—of—way, so as to be able to
determine the productivity of these forest soils in the
area.

IOO�N — AdO�
The number of woodland acres that would affect any
watersheds in the�area, if the Woodland was removed.
If woodland is involved, it is hoped that the timber could
be merchandised and sold to lessen the need for piling and
burning of debris during right-of-way construction.
Provisions should be indicated in the EIS that the
contrac[or will make all efforts to salvage any merchantable
timber to permit construetion, once the contractor takes
charge of the right-of-way.
6. The provisions that-Ghe�•contractor will take during the
constructiofl phase to prevent erosion, sedimentation and
construction damage to�Ehe remaining standing trees outside
" of the right-of-way boundary and construction limits.
We would hope that a route could be chosen, that would have the
least impact to forest and related resources in that area.

WHAT IS AN E.I.S. � �
E.I.S. is an abbceviation for Environmental.Impact Statement. In any proposed con-
struction of a new roadway or significant improvement to an existing roadway, an
analysis is needed to determine the relationship betveen the monetary benefits and
costs to be derived from such an improvement. In addition to the economic analysis,
a detailed assessment of the proposed development's impact on the environment is
required, including natural cesources, histocic and architectural resources,
archaeological conditions, socioeconomic and land use characteristics, displacement
and relocations, traffic, air quality, and noise.
� The North Carolina DepartJnent of Transpottation (NCDOT) and Hensley-Schmidt, Inc. are �
accomplishing an E.I.S. for the proposed upgrading of US Route 421" from the
; intersection of S.R. 194 and US Route 421 to just vest of the South Fork New River
Bridge. It vill be our job to determine what improvements are needed-to meet future
anticipated traffic volumes, whether a nev alignment or an improvement of the
existing roadvay will provide the most positive and least negative benefits, and the
environmental consequences of each.
Work is progressing and is expected to be rnmpleted on schedule, vith submission of a
Draft Environmental Impact Statement for reviev in mid 1989. The Draft Environmental
Impact Statement vill describe the possible alternatives for improvement of US Route
421 and theit respective impacts on the environment and economic benefits.
TELEPHONE HOTLINE
To better provide information and to ansWer questions concerning the proposed improve-
ments to US Route 421 and the Environmental Impact Statement progress, a toll free
telephone number has been established for citizens' direct comnunication to the
Hensley-Schmidt, Inc. engineecs. The toll free number is available foc project calls
from 8:30 a.m. to 5:30 p.m. Monday thcough Friday. Calls should be directed to Mr.
Steve Thomas, P.E., Project Engineec or Mr. Paul Griggs, P.E., Project Manager.

PUBLIC INVOLVEMENT PROGRAM
A public involvement program has been established not only to better infocm those who
are interested in the project, but also to help us accomplish this study. Feedback
ftom local public officials and citizens is very important in determining what
improvements are needed, possible locations for nea alignments, and the locations of
known environmentally sensitive areas, historic sites, archaeological sites, etc.
Following is the program as developed by the NCDOT and Hensley-ScFunidt, Inc. to
provide for public involvement in the US 421 improvements project:
- Preparation and distribution of fouc informative Newsletters thcoughout the
study.
- Establishment of a Post Office Box and Toll Fcee Telephone Number for direct
communication.
- Elected Officials informational meetings. �
- Public workshops/Meetings to be held at two strategic times during the study
process.

FIRST PUBLIC MEETING HELD
� On January 17, 1989, the first of tvo public meetings was held by the NCDOT and
Hensley-Schmidt, Inc. personnel. Repcesenting-the NCDOT Were Dr. David Modlin, P.E.
and Ms. Gail Grimes, P.E., both With the Planning and Research Bcanch, and Mr. Dave
Cochcan, P.E_ With the Design Services Dranch. Hensley-Schmidt. Inc. vas cepresented

At this first meeting the proposed alternative constcuction corcidors Were shovn. A
formal pcesentation uas made by the NCDOT and Hensley-Sclunidt. Inc. With the need foc
the improvements discussed, the process of the E.I.S. outlined, and a bcief
description of the proposed alternative construction corridors and the "Improve
Existing Alignment" alternative. Enclosed in this newsletter is a map showing all of
the possible corridoc segments numbered from 1 to 4. �
The success of this first public meeting is obvious by the infocmation learned by the
engineers. The location of several potential histocic and archaeological sites,
including cemeteries, was pointed out to us by local citizens.
WHAT NEXT �
Utilizing cortments and cecommendations received from the ficst public meeting the
many possible alternative alignment corridors as shown at that meeting Will be
reduced in numbec by eliminating those that are determined to be impcactical due to
enviconmental impact oc cost. The end result of this process Will be the
establishment of the preliminary alternatives. These pceliminacy alternatives would
then be studied in detail for environmental impacts, construc.tion costs, and traffic
handling characteristics. In addition to the study of these alternatives vill be the
"do nothing" alternative, and an upgrading and improving of existing US Route 421
alignment.
Once the study alternatives are established another neNSletter Will be sent out to
inform you of the ones vhich are selected. Another public meeting Will also be held
in late Spring for public presentation and feedback on the findings of the
environmental impacts, construction costs, and traffic handling chacacteristics of
each selected alternative.

As part of the continued public involvement program, the NCDOT along with Hensley-
. Schmidt, Inc. have scheduled the second public meeting/workshop for May 18, 1989, at
' the Boone Council Chambers from 6:30 p.m. to 9:00 p.m. This meeting is being held to
present the current findings of the Environmental Impact Statement (E.I.S.) which
covers US Route 421 from the NC 194/US 421 Intersection to just west of the South
Fork New River. At this meeting the alternatives considered for further study will
also be presented.

It is important to realize that at this meeting the one preferred alternative
recommendation will not yet have been made. In a usual E.I.S. process the findings
by Hensley-Schmidt, Inc. (those same findings that will be presented at this upcoming
public meeting) will be used and documented in the preliminary E.I.S. submittal.
Upon review and approval by the public and the required public officials, a
recommendation will be made. The preliminacy E.I.S. submittal is scheduled for late
June, 1989.
PROGRESS OF THE STUDY ,
Work has progressed from our last public meeting in most aspects of the study. Fram
our last public meeting where all of the possible study routes were presented, we
have narrowed down the number to two Alternative Corridor Routes, Improve Existing
Corridor, and the No-Build Alternative. These routes are all presented in the
schematic on the back page of this newsletter.
Due to the unusually wet winter, some aspects of the study such as historic,
architectural, and archaeological field work have been delayed. The review of the
flora and fauna (plants and animals) must wait until the beginning of wacm weather.
Other than these aspects of the study, the remaining study topics such as the
economic analysis, socio-economic and land use characteristics, number of
displacements and relocations, traffic, air quality, and noise analysis are all
nearing completion with results to be presented at the upcoming public meeting.
Following is a brief description of selected study topics and what has happened in
each.
.NOISE -
Hensley-Schmidt, Inc. personnel were in the Boone area during the week of April lOth
to measure existing noise levels at selected locations. The measurement of existing
noise levels is used to help detecmine future noise levels for each of the
Alternatives. The Federal Highway Administration (FHWA) has determined that noise
levels should not exceed 65 dBA for residences and 70 d9A foc Cortme[cial areas. To
help in understanding these levels the figure on the right below shows characteristic .
I10132 levels for different activities. [oMUON o�i000rt rqISELEVEL COMYpN iHOOOa

The impact resulting from the construction of a new highway or the improvement of an
existing highway can range from aggravating existing air pollution problems to
improving the ambient air conditions. In order to ensure that any proposed improve-
ment or construction of a roadway will not adversely affect the health of the general
public, the FHWA has estatilished ambient air quality standards (i.e. allowable
pollutant parts per million) for all pollutants. The pollutants that are most
produced by automobiles are carbon monoxide (CO), hydrocarbons (HC), and nitrogen
oxides. Preliminary study results show that no adverse air quality should be
experienced from any of the alternatives.
_.OTHER _ _____
Results from other study topics are being finalized as of this newsletter. Within
the next couple of weeks you should see more and more of our personnel in your area
taking measurements and readings of every type imaginable. By the time of our next
public meeting all of our results shall be in for your review and comments.
