APPROVAL of 401 Water Quality Certification
Mr. Bill Gilmore
NC DOT
PO Box 25201
Raleigh, NC 27611-5201
Dear Mr. Gilmore:
You have our approval, in accordance with the attached conditions, for the purpose of widening Airport Blvd., as
you described in your application dated August 26, 1998. After reviewing your application, we have decided that this fill
is covered by General Water Quality Certification Number 3103. This Certification allows you to use Nationwide Permit
Number 14 when the Corps of Engineers issues it. This Certification is also covered by Neuse Buffer Rules. In addition,
you should get any other federal, state or local permits before you go ahead with your project including (but not limited to)
Sediment and Erosion Control, Coastal Stormwater, Non-Discharge and Water Supply Watershed regulations. Also this
approval will expire when the accompanying 404 or CAMA permit expires unless otherwise specified in the General
Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application for a new certification. If the property is
sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for complying
with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory mitigation
may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the conditions
listed in the attached certification.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh,
N.C. 27611-7447. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you
have any questions, please telephone John Domey at 919-733-1786.

ATTENTION: Mr. Eric Alsmeyer
Dear Mr. Alsmeyer:
Subject: Wake County, Widening of Airport Boulevard (SR 3015) from NC 54 to
I-40. TIP No. U-3344, State Project 9.8051709.
The N.C Department of Transportation (NCDOT)'proposes to widen Airport Boulevard
(SR 3015) beginning at NC 54 and extending northeast to just beyond SR 1789 (Pleasant
Grove Church Road) in western Wake County. The widening will be constructed as a
five-lane roadway with curb-and-gutter. The length of the project is approximately 2.3
miles.
NCDOT completed an Environmental Assessment (EA) for this project in 1996 and a
State Finding of No Significant Impact (FONSI) in 1997. The alternatives considered for
the project included No-Build, postponing improvements, and various construction
schemes to widen the road. The recommended alternative is a combination of
asymmetrical and symmetrical widening of the existing road. The design was developed
to improve existing geometric characteristics of the road while avoiding wetlands,
residences, businesses and a cemetery.
According to the final design, the project will have fewer impacts to waters of the United
States than was presented in the EA and FONSI. The project will not require additional
impacts to the unnamed tributary of Crabtree Creek or the 0.03 acres of wetlands
identified in the documents. However, two existing culverts will need to be extended.
The existing 2@ 2.1m x 2.4m reinforced concrete box culvert in an unnamed tributary of
Stirrup Iron Creek will be extended by 55.7 feet. The existing 3@ 3m x 3m reinforced

concrete box culvert at Stirrup Iron Creek will be extended by 61 feet. These culvert
extensions are the project's only impacts to waters of the United States.
It is expected that this project can be authorized under Nationwide Permit No. 14 for road
crossings, and could also be authorized under the proposed revisions to Nationwide
Permit No. 14 (Linear Transportation Projects). Although notification for this work may
not be required, the NCDOT would appreciate your agency's review of this work since
the status of NWP 14 is under review. Enclosed you will find a completed pre-
construction notification form, site maps, drawings of the proposed culverts, delineation
sheets from the two sites, and a letter from the SHPO.
By copy of this information NCDOT requests the N.C Division of Water Quality to
review this work for authorization under General Water Quality Certification No. 3103.
If you need any additional information, please call Mr. Gordon Cashin at [phone]
extension 278.
Sincerely,
(:&6? - - I

10b. Summary Sheet
Culvert Extention #1:
Length of original culvert: 96.5 ft./29.4 meters
Length of proposed extension: 55.7 ft./17.0 meters
Width of stream prior to culvert extension: 3.0 ft./0.9 meter
Width of stream after culvert extention: 1.5 ft./0.46 meters
Average depth of stream prior to culvert extension: 1.5 ft./0.46 meters
Average depth of stream after culvert extension: 1.5 ft/0.46 meters
Culvert Extention #2:
Length of original culvert: 84.3 ft./25.7 meters
Length of proposed extension: 61.0 ft./ 18.6 meters
Width of stream prior to culvert extension: 4.5 ft./1.4 meter
Width of stream after culvert extention: 4.5 ft./1.4 metes
Average depth of stream prior to culvert extension: 1.5 ft./0.46 meter
Average depth of stream after culvert extension: 1.5 ft./0.46 meter
12. The proposed project consist of the widening of SR 3015 (Airport Blvd.) from NC 54 to
I-40 to five lanes with curb and gutter. This widening will require a 61.0 foot (18.6
meter) extension of a triple barrel 3.2 meter box culvert along Stirrup Iron Creek and a
55.7 foot (17.0 meter) extension to a double-barrel 2.1 meter box culvert along an
unnamed tributary to Stirrup Iron Creek. The total stream impact for both extension is
116.7 feet (35.6 meters).
Note: The unnamed tributaries to Crabtree Creek, as shown on the attached USGS map,
have been previously impacted by private development. Photos of each stream crossing
are attached.
14. STATE REASONS WHY IT IS BELIEVED THAT THIS ACTIVITY MUST BE CARRIED
OUT IN WETLANDS. (INCLUDE ANY MEASURES TAKEN TO MINIMIZE WETLAND
IMPACTS): Because this vroiPrr involves the widening to an existing road, with
existing stream crossings, avoidance of the streams is not feasible. However,
impacts to the stream have been minimized by widening existing culverts rather
than proposing to construct a roadway on new location.

We have received information concerning the above project from the State
Clearinghouse.
We have conducted a search of our files and are aware of no structures of
historical or architectural importance located within the planning area. Therefore,
we recommend that no historic architectural survey be conducted for this project.
There are no known archaeological sites within the proposed project area. Based
on our present knowledge of the area, it is unlikely that any archaeological
resources which may be eligible for inclusion in the National Register of Historic recommend that
Places will be affected by the project construction. We, therefore, no archaeological investigation be conducted in connection with this project.
These comments are made in accord with G.S. Renee Executive
Gledhill-Earley, Order XVI.
If you have any questions regarding them, please contact
environmental review coordinator, at 919/733-4763.

State Project DOT No. 9.8051709, T.I.P. No. U-3344; EHNR # 98-0018
The referenced document has been reviewed by this office. The Division of
Water Quality (DWQ) is responsible for the issuance of the Section 401 Water
Quality Certification for activities which impact waters of the state including
wetlands. The proposed work would involve fill in approximately 0.03 acre of
jurisdictional wetlands at one location. Linear distances of perennial stream
impacts (culverting and/or channel changes) were not quantified. DWQ offers
the following comments based on the document review:
A) This project will involve culvert extensions and/or channel
changes at three locations, although the linear distances of these
stream impacts were not included in the FONSI. If culvert extensions
and/or channel changes exceed 150 feet linear distance of additional
perennial stream impacts at any single crossing, stream mitigation will
be required in accordance with current DWQ Wetland Rules 115A NCAC
2H.0506(b)(6)}. If necessary, said stream mitigation proposal should be
included with the permit application. The Wetland Restoration Program
will be available to use for stream mitigation for this project.
B) We encourage NCDOT to investigate whether or not temporary fill will
be required to build haul roads and place culverts. We suggest that
NCDOT include this information with the permit application. NCDOT is
advised that full restoration of any temporary fill areas will be required
in accordance with Condition #4 of General Certification 3114
(Nationwide Permit 33). On May 27, 1997, DWQ submitted a draft
restoration policy for temporary impact areas to NCDOT. We anticipate
finalization of this policy prior to the construction of this project.
C) DWQ asks NCDOT to stipulate that borrow material will be taken
from upland sources in the construction contract awarded for this
project.

Page 2 of 2
Based upon the wetland impacts described in the FONSI, General Certification
No. 3103 will be applicable to this project. Final permit authorization will
require formal application by NCDOT and written concurrence from DWQ.
Please be aware that this approval will be contingent upon evidence of
avoidance and minimization of wetland and stream impacts to the extent
practical, and provision of wetland and stream mitigation where necessary.
DWQ appreciates the opportunity to provide comments on the FONSI. NCDOT is
reminded that issuance of a 401 Water Quality Certification requires
satisfaction of water quality concerns, to ensure that water quality standards
are met and no wetland or stream uses are lost. Questions regarding the 401
Certification should be directed to Cyndi Bell at [phone] in DWQ's Water
Quality Environmental Sciences Branch.

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

3. Description of the Proposed Project
NCDOT proposes to widen SR 3015 (Airport Boulevard) beginning at NC 54 and extending northeast
to just beyond SR 1789 (Pleasant Grove Church Road) in western Wake County. The widening will
be constructed as a five-lane roadway with curb-and-gutter. The length of the project is approximately
3.4 kilometers (2.3 miles). The project is included in the 1998-2004 NCDOT Transportation
Improvement Program (TIP) as TIP No. U-3344. Construction is scheduled to begin in Fiscal Year
1998. The estimated cost of the project is $ 6.0 million, including $2.15 million for right-of-way and
$ 3.85 million for construction.
4. Recommended Alternative
Alternatives considered for the project included No-Build, postponing improvements, and various
construction schemes to widen the road. The No-Build Alternative would avoid negative impacts
associated with construction. However, traffic flow in the No-Build Alternative would break down
as increasing numbers of motorists are projected to travel on SR 3015 (Airport Boulevard).
Postponing the project would make construction more difficult and costly due to worsening congestion
and continued development of adjacent land. To relieve the current traffic congestion and adequately
serve the projected increases in traffic volumes on SR 3015 (Airport Boulevard), construction of a
five-lane roadway is required (See Figure 1). The recommended alternative is a combination of
symmetrical and asymmetrical widening of the existing road. The functional design was developed
to improve existing geometric characteristics of the road while minimizing impacts to a small wetland
and avoiding residences, businesses, and a cemetery (See Figure 2). The proposed design speed for
the improved roadway is 80 kilometers (50 miles) per hour. No control of access is proposed.

5. Environmental Commitments
Environmental commitments for the proposed action include the following:
A. All standard procedures and measures, including Best Management Practices, will be
implemented to avoid or minimize environmental impacts.
B. Any underground storage tanks discovered during construction will be reported to the North
Carolina Division of Water Quality.
C. The final designs will be coordinated with appropriate state and local officials and the Federal
Emergency Management Agency (FEMA) to assure compliance with FEMA, state, and local
floodway regulations.
-3-
6. Environmental Impacts
Construction of the proposed project will help meet traffic needs for the commercial and industrial
developments along SR 3015 (Airport Boulevard), for access to Raleigh-Durham International
Airport, and for commuters to other major employers in the region. SR 3015 (Airport Boulevard) is
designated as a major thoroughfare from McCrimmon Parkway to I-40 on the Greater Raleigh Urban
Area Thoroughfare Plan. Key intersections already experience unacceptable congestion. The
proposed project will improve the level of service for the projected traffic volumes.
Environmental impacts will include the following:
• Removal of three dilapidated and unoccupied buildings.
• Acquisition of 1.74 hectares (4.29 acres) of land for right-of-way and use of 1.38 hectares (3.4
acres) of land for construction easements.
• Relocation of utilities including overhead electrical, telephone, and fiber optic lines; a gas line;
and several street lights, fire hydrants, poles, and utility boxes.
• Increases in noise levels that will exceed the FHWA noise abatement criteria for 19 residences
and one hotel (> 66 dBA), along with three business properties (one abandoned) (> 71 dBA).
• Clearing and grading of 1.01 hectares (2.5 acres) of mixed pine/hardwood forest and 3.33
hectares (8.2 acres) of disturbed land.
• Fill of a portion of forested wetland adjacent to an unnamed tributary to Crabtree Creek; the
impact has been minimized, resulting in the unavoidable taking of 0.014 hectare (0.03 acre).
• Enlarging or lengthening of three drainage structures at the Morrisville Tributary to Crabtree
Creek, at Stirrup Iron Creek, and at a tributary to Stirrup Iron Creek.
• Disturbance of 0.93 hectare (2.3 acres) of floodplain.
-4-

t

pil

The proposed project will not displace any residents or businesses. No adverse impacts will occur to
air quality, long-term water quality, cultural resources, protected species, hazardous material sites, or
known underground storage tanks. Documentation from the Deputy State Historic Preservation
Officer (see Appendix) recommends that no historic structure survey nor archaeological investigation
be conducted. A file search by the N.C. Department of Cultural Resources revealed no known sites
already listed in the National Register.
7. Wetland Finding
Executive Order 11990 establishes a national policy to avoid, to the extent possible, adverse impacts
on wetlands and to avoid direct or indirect support of new construction in wetlands wherever there is
a practicable alternative. The recommended alternative will involve the unavoidable taking of a
portion of forested wetland when the segment from NC 54 to McCrimmon Parkway is constructed.
The wetland was delineated in November 1995 and reviewed on-site by a representative of the U.S.
Army Corps of Engineers. Based on a survey of the delineated boundaries, the total area of the
wetland is 0.09 hectare (0.22 acre). Alignment alternatives that would completely avoid the wetland
would impact a business across the street and would result in unacceptable geometrics. Minimization
has been employed in the planning analyses so that the recommended alternative will impact the
wetland at the narrowest point possible given adjacent development constraints. Therefore, there is
no practicable alternative to avoid taking approximately 0.014 hectare (0.03 acre) of this wetland.
8. Floodplain Finding
The objectives of Executive Order 11988, "Floodplain Management," and DOT Order 5650.2,
"Floodplain Management and Protection," are to avoid adverse impacts due to occupancy and
alteration of the 100-year floodplain unless that location is the only practicable alternative. In such
circumstances, it is required that every effort must be made to minimize the potential risks to human
safety and property, and to minimize negative effects on natural and beneficial floodplain value. The
preferred alternative will be developed to comply with these orders and with North Carolina Executive
Order 123, "Uniform Floodplain Management Policy."
-5-

The proposed alignment will involve approximately 0.93 hectare (2.3 acres) of floodplain, based on
Federal Emergency Management Agency (FEMA) floodplain maps. The project has been designed
such that the floodway will carry the 100-year flood without increasing the water elevation more than
one foot at any given point. The dimensions of the drainage structures and the roadway grades have
been designed to avoid increasing the flood hazard in the project area. The project has been and will
continue to be coordinated with appropriate state and local officials and with FEMA to ensure
compliance with state, local, and FEMA floodway regulations. Therefore, in accordance with the
Executive Order 11988 and 23 CFR 650, Subpart A, the proposed project will not cause a significant
floodplain encroachment.
Methods to minimize harm and preserve the floodplains include minimizing fill and grading
requirements, preserving the free natural drainage whenever possible, maintaining vegetation buffers,
controlling urban runoff, and minimizing erosion and sedimentation during construction.
9. Permits
Section 401 of the Clean Water Act requires each state to certify that state water quality standards will
not be violated for activities that: (1) involve issuance of a federal permit of license or (2) require
discharges into "waters of the United States." Accordingly, 401 Water Quality Certification will be
required by the N.C. Department of Environment, Health, and Natural Resources--Division of Water
Quality. In addition, Section 404 of the Clean Water Act requires permitting from the Corps of
Engineers for activities that involve discharge into "waters of the United States" including
jurisdictional wetlands. Because of the size (0.03 acre (0.014 hectare)) of the wetland area to be
impacted by the proposed project, it is anticipated that Nationwide Permit 14 for Roadway Crossings
will be applicable. A letter of notification will be sent to the Corps of Engineers and the Division of
Water Quality for their approval. The final permit decision will be at the discretion of the two
agencies.

10. Circulation of the Environmental Assessment
The Environmental Assessment (EA) was approved by NCDOT on July 18, 1996. The approved EA
was distributed to the following Federal, State, and local agencies. An asterisk (*) denotes that a
response was received. Copies of correspondence are included in the Appendix of this document.
• U.S. Army Corps of Engineers*
• U.S. Fish and Wildlife Service*
• U.S. Fish and Wildlife Service, Fish & Wildlife Enhancement
• N.C. Department of Administration*
• N.C. Department of Cultural Resources
• N.C. Department of Public Instruction
• N.C. Department of Environment, Health, and Natural Resources*
• N.C. Wildlife Resources Commission*
• Town of Morrisville
• Wake County
In addition, data collection and coordination efforts have been ongoing with the Town of Morrisville,
Wake County, and Capital Area Metropolitan Planning Organization.
11. Comments Received on the Environmental Assessment
Written comments on the Environmental Assessment were received from five agencies (see letters in
Appendix). The following is a summary of these comments with responses where appropriate.
U.S. Department of the Army, Corps of Engineers
Letter dated: October 24, 1996
Comment: Enclosed for your information is a copy of the Federal Emergency Management
Agency's "Procedures for 'No Rise' Certification for Proposed Developments in Regulatory
-7-

Floodways." In addition, we suggest coordination with the communities for compliance with their
flood ordinances and any changes, if requires, to the flood insurance maps and report.
Response: This project will be designed to comply with all FEMA requirements.
Comment: Based on information presented in the document, it appears that the impacts to
jurisdictional waters, including wetlands, are minor, and it is probable that the work could be
authorized under one or more nationwide or regional general permits.
Response: NCDOT will apply for the appropriate permit(s) prior to construction.
North Carolina Department of Environment, Health, and Natural Resources
Division of Land Resources
Letter dated: August 19, 1996
Comment: The project will impact 1 geodetic survey marker.
Response: During a follow-up telephone conversation, the Division of Land Resources
acknowledged that it had incorrectly identified a geodetic marker that already had been removed
during construction of I-40.
Comment: The erosion and sedimentation control plan required for this project should be
prepared by the Department of Transportation under the erosion control program delegation to the
Division of Highways from the North Carolina Sedimentation Control Commission.
Response: NCDOT will prepare an erosion control plan under delegation of responsibility from
the North Carolina Sedimentation Control Commission.
-8-

North Carolina Department of Environment, Health, and Natural Resources
Letter dated: September 9, 1996
Comment: 401 WQC may be denied if wetland and water impacts have not been minimized to
' the maximum extent practicable.
Response: As concurred with by the U.S. Fish and Wildlife Service and the U.S. Army Corps
of Engineers (see letters in Appendix), NCDOT has considered appropriate alternatives and has
minimized impacts to wetlands.
1 North Carolina Wildlife Resources Commission
Letter dated: September 11, 1996
Comment: We will concur with the EA for this project and anticipate our concurrence with the
Finding ofNo Significant Impact (FONSI). NCDOT should continue efforts to minimize impacts and
should employ NCDOT Best Management Practices to protect off-site resources.
' Response: NCDOT will employ Best Management Practices to protect off-site resources.
' 12. Comments Received During and Following the Public Hearing

by the citizens, and no written comments were submitted to NCDOT during or after the hearing.

13. Revisions to the Environmental Assessment

Subsequent to circulation of the Environmental Assessment, NCDOT determined that the project's
' northern terminus should be extended across I-40. Widening this three-lane section of roadway will
prevent bottleneck congestion between the improved RDU Airport interchange and the remainder of

-9-

SR 30'15 (Airport Boulevard). The additional section is shown on Figure 2E. Based on preliminary
plans and an on-site review, no additional impacts are anticipated. The bridge over I-40 is wide
enough to accommodate four lanes with restriping. Where widening of the roadway is necessary,
construction will be limited to disturbed areas within existing right-of-way. Several sections of SR
3015 (Airport Boulevard) and one lane of SR 1789 (Pleasant Grove Church Road) are proposed to
be widened by as much as 1.8 meters (six feet). The construction cost estimate for this additional
section is $350,000, which is reflected in the revised total of $6.0 million. No wetlands or natural
habitat will be affected.
Figure 2 also includes labels for three underground storage tank sites that were identified in the
Environmental Assessment, but not shown graphically.
The revised project length is 3.4 kilometers (2.3 miles). The revised amount of disturbed land to be
impacted is 3.33 hectares (8.2 acres). No additional revisions to the Environmental Assessment are
necessary.
14. Basis for a Finding of No Significant Impact
Based upon a study of the proposed project as documented in the Environmental Assessment, and
upon comments received from Federal, State, and local agencies, it is the finding of the North Carolina
Department of Transportation that the project will not have a significant impact upon the human or
natural environment. Therefore, an Environmental Impact Statement will not be required.

1. FLOOD PLAINS: POC - Mr. Bobby L. Willis, Special Studies and Flood Plain
Services Section, at [phone]
The proposed project is located within the jurisdictional limits of the towns of Cary
and Morrisville, both of which participate in the National Flood Insurance Program.
From your Project Area/Impacts Maps contained in the Environmental Assessment, and
Panels 284, 292, and 293 of the March 1992 Wake County, North Carolina and
Incorporated Areas Flood Insurance Rate Map, it appears that the proposed project will
cross two flood insurance study streams: Morrisville Tributary (Basin 18, Stream 26)
and Stirrup Iron Creek (Basin 18, Stream 12). Both of these are detail study streams
with 100-year flood elevations determined and a floodway defined. Enclosed for your
information is a copy of the Federal Emergency Management Agency's "Procedures for
'No Rise' Certification For Proposed Developments in Regulatory Floodways." In
addition, we suggest coordination with the communities for compliance with their flood
ordinances and any changes, if required, to the flood insurance maps and report.
2. WATERS AND WETLANDS: POC - Mr. Eric Alsmeyer, Raleigh Field Office,
Regulatory Branch, at [phone], Extension 23
Our review indicates that the information in our November 2, 1995, letter on the
project is still valid. A copy of the letter is contained in Appendix A of the
Environmental Assessment.
Based on information presented in the document, it appears that the impacts to
jurisdictional waters, including wetlands, are minor, and it is probable that the work
could be authorized under one or more nationwide or regional general permits.
Questions or comments pertaining to permits may be directed to Mr. Alsmeyer.

Thank you for your letter of August 1, 1996 requesting comments from the U.S.
Fish and Wildlife Service (Service) on the State Environmental Assessment
(SEA) dated July 18, 1996, for the widening of State Road (SR) 3015 (Airport
Boulevard), (TIP No. U-3344), Wake County, North Carolina. This report is
provided in accordance with provisions of the Fish and Wildlife Coordination
Act (16 U.S.C. 661-667d) and Section 7 of the Endangered Species Act (ESA) of
1973, as amended (16 U.S.C. 1531-1543).
According to the SEA, the North Carolina Department of Transportation (NCDOT)
proposes to widen and improve SR 3015 from the existing two lanes along most
of its length to a five-lane curb and gutter facility. Most of the widening
would be symmetrical along the existing roadway. The total length of the
proposed project would be 1.7 miles.
Alternatives Analysis
Chapter 3 of the SEA considers alternatives for the project. The Service is
pleased that the NCDOT considered symmetrical, asymmetrical, and a combination
of these widening designs and that the required transportation improvements
can be made by widening the existing road. We consider the analysis of
alternatives to be adequate.
Wetlands
Section 4.10.5 of the SEA considers project impacts on wetlands. Preliminary
plans indicate that wetland impacts would be minimal and consist of
approximately 0.03 acres. The Service is pleased that the planned alignment
was shifted to minimized wetland impacts. Based on data in the SEA the
Service believes that the NCDOT has endeavored to avoid and minimize wetland
impacts associated with this project.
Federally Protected Species
Section 4.10.4 notes that Wake County is known to contain four species
protected by the ESA. These are the bald eagle (Haliaeetus leucocephalus),
red-cockaded woodpecker (Picoides borealis), dwarf wedge mussel (Alismidonta
heterodon), and Michaux's sumac (Rhus michauxii). While the SEA indicates (p.
31) that the bald eagle is endangered, this species was recently downlisted to
a status of threatened. The other species are listed as Federally endangered.
The SEA states that the NCDOT has determined that the project would have no
effect on these species. The discussion of the efforts made by the NCDOT to
evaluate potential impacts on these species is thorough and well done. We are
especially pleased by the efforts made to ensure that a bald eagle seen near
the project area would not be impacted. We also appreciate the fact that
recent field surveys were made for the dwarf wedge mussel and Michaux's sumac.

Based on the information supplied by the NCDOT and the assumption that '
stringent water quality and erosion control procedures will be employed during
construction, the Service concurs that this project is not likely to adversely
affect any Federally-listed endangered and threatened species, their formally '
designated critical habitat, or species currently proposed for Federal listing
under the ESA, as amended.
We believe that the requirements of Section 7 of the ESA have been satisfied. ,
We remind you that obligations under Section 7 consultation must be
reconsidered if: (1) new information reveals impacts of this identified action
that may affect listed species or critical habitat in a manner not previously
considered; (2) this action is subsequently modified in a•mannd'r that was not '
considered in this review; (3) a new species is listed or critical habitat
determined that may be affected by the identified action.
Summary ,
The Service believes that the SEA adequately describes the purpose and need
for the project, the alternatives considered, and the environmental impacts of
the project. Based on information contained in the SEA, the Service would '
support a Finding of No Significant Impact (FONSI) for this project.
The Service appreciates the opportunity to comment on this project. Please
continue to advise us of the progress made in the planning process, including
your official determination of the impacts of this project. If our office can
supply any additional information or clarification, please contact Howard Hall
at (919)-856-4520 (ext. 27).

We have received information concerning the above project from the State
Clearinghouse.
We have conducted a search of our files and are aware of no structures of
historical or architectural importance located within the planning area. Therefore,
we recommend that no historic architectural survey be conducted for this project.
There are no known archaeological sites within the proposed project area. Based
on our present knowledge of the area, it is unlikely that any archaeological
resources which may be eligible for inclusion in the National Register of Historic
Places will be affected by the project construction. We, therefore, recommend that
no archaeological investigation be conducted in connection with this project.
These comments are made in accord with G.S. 121-12(a) and Executive Order XVI.

Staff biologists with the N. C. Wildlife Resources Commission have reviewed the subject EA and
are familiar with habitat values in the project area. The purpose of this review was to assess project
impacts to fish and wildlife resources. Our comments are provided in accordance with certain provisions
ofthe North Carolina Environmental Policy Act (C.S. l 13A-1 et seq., as amended; i NCAC 25).
' NCDOT proposes to widen SR 3015 to a five-lane curb and gutter facility from NC 54 to I-=0.
Project length is approximately 1.7 miles. Wetland and waters impacts are associated with stream
crossings and one small wetland and total approximately 0.03 acres.
The EA provides an adequate discussion of anticipated impacts to fish and wildlife resources in the
' project area. Due to the disturbed nature of the project area, we feel that impacts to natural resources
will be minimal.
' We will concur with the EA for this project and anticipate our concurrence with the Finding of No
Signif ic.Int lrrupact. (F'ONS1). NCDO'I should continue efforts to minimize impacts and should employ
?vC:I)01' Hcst Managcmcnt Practices to protect off-site resources.

3. Actions Required By Other Agencies
A-Section 401 Water Quality Certification will be required from the NorthCarolina Department
of Environment, Health, and Natural Resources, Division of Environmental Management. While
no permits from the U.S. Army Corps of Engineers are anticipated to be required, a letter of
notification will be submitted for approval. If requested by the Corps, a Nationwide Permit
application will be prepared.
4. Proposed Project
NCDOT proposes to widen SR 3015 (Airport Boulevard) from NC 54 to the I-40 eastbound
ramps in western Wake County. The widening will be constructed as a five4ane roadway with
icurb-and=gutter. The length of the project is approximately 2.8 kilometers (1.7 miles). The
project is included in the 1997-2003 NCDOT Transportation Improvement Program (TIP) as TIP
No. U-3344. Construction is scheduled to begin in Fiscal Year 1997. The estimated cost of the
project is $5.15 million, including $2.15 million for right-of-way and $3.0 million for
construction.

6. Description of the Project Area
The project area is located in the town of Morrisville in Wake County. The southern terminus is
NC 54, and the northern terminus is the I-40 eastbound ramps. Zoned for mostly industrial and
commercial uses, the project area is heavily developed and includes Perimeter Park and Triangle
Factory Shops.
Environmental features in the project area include Stirrup Iron Creek and its tributary, a tributary
to Crabtree Creek, and a small wetland. Also located in the vicinity are the Sorrell Grove Baptist
Church and the Sorrell Grove Community Cemetery.
6. Alternatives Considered
To relieve the current traffic congestion and adequately serve the projected increases in traffic
volumes on SR 3015 (Airport Boulevard), afive-lane roadway is required. Both symmetrical
and asymmetrical alignments of the widening were considered, and the functional design was
developed to improve existing geometric characteristics of the road while avoiding residences,
businesses, and a cemetery. Postponing the project would make construction more difficult and
costly due to worsening congestion and continued development of adjacent land. The No-Build
Alternative would avoid negative impacts associated with construction. However, traffic flow in
the No-Build Alternative would break down as increasing numbers of motorists are projected to
travel on SR 3015 (Airport Boulevard). With the No-Build Alternative, proposed industrial
development in the project area would be hindered.
7. Environmental Impacts
Construction of the proposed project will help meet traffic needs for the commercial and
industrial developments along SR 3015 (Airport Boulevard) and for commuters to other major
employers in the region. SR 3015 (Airport Boulevard) is designated as a major thoroughfare
from McCrimmon Parkway to I-40 on the Greater Raleigh Urban Area Thoroughfare Plan. Key

intersections already experience unacceptable congestion. The proposed project will improve
the level of service for the projected traffic volumes.

Environmental impacts will include the following:
' Removal of up to three dilapidated and unoccupied buildings.
• Acquisition of 1.74 hectares (4.29 acres) of land for right-of-way and use of 1.38 hectares
' (3.4 acres) of land for construction easements.
• Relocation of utilities including overhead electrical, telephone, and fiber optic lines; a gas
' line; and several street lights, fire hydrants, poles, and utility boxes.
• Increases in noise levels that will approach or exceed the FHWA noise abatement criteria

' (66 dBA) for 19 residences and three business properties located along the existing
roadway
.
• Clearing and grading of 1.01 hectares (2.5 acres) of mixed pine/hardwood forest and 3.18
' hectares (7.84 acres) of urban/disturbed land.
• Fill of 0.014 hectare (0.03 acre) of forested wetland adjacent to an unnamed tributary to
' Crabtree Creek.
• Enlarging or lengthening of three drainage-structures at a tributary to Crabtree Creek, at
' Stirrup Iron Creek, and at a tributary to Stirrup Iron Creek.
• Disturbance of 0.93 hectare (2.3 acres) of floodplain.
'
The proposed project will not displace any residents or businesses. No adverse impacts will
' occur to air quality, long-term water quality, cultural resources, protected species, hazardous
material sites, or known underground storage tanks.
8. Coordination
' Federal, state, regional, and local agencies have been consulted during this environmental study.
A scoping letter, identifying the project and requesting comments, was distributed to the
following agencies:

Chapter 1
Project Description
1.1 General Description
The North Carolina Department of Transportation (NCDOT) proposes to widen and improve
SR 3015 (Airport Boulevard) in western Wake County (see Figure 1). Widening the roadway to five
lanes with curb-and-gutter is proposed along approximately 2.8 kilometers (1.7 miles).
The existing roadway is two lanes for most of this length, with driveways and intersections
providing industrial, commercial, and residential access. In the Greater Raleigh Urban Area
Thoroughfare Plan (see Figure 2), SR 3015 (Airport Boulevard) is designated as a minor
thoroughfare from NC 54 to McCrimmon Parkway and as a major thoroughfare from McCrimmon
Parkway to I-40.
Widening of SR 3015 (Airport Boulevard) is needed to accommodate projected traffic volumes and
improve access to industrial and commercial developments, including Triangle Factory Shops (in
the Concourse development) and Perimeter Park. Additional industrial developments are proposed
or under construction along the roadway.
1.2 Characteristics of Existing Facility
1.2.1 Typical Section
The current width of SR 3015 (Airport Boulevard) varies throughout the project area. Except for
turning lanes at Perimeter Park Drive and the Enterprise Industrial Center, the roadway is two lanes
wide from the NC 54 intersection to just south of Slater Road, where it widens to three lanes. At the
I-40 ramps, the roadway is five lanes wide, with one through lane on each side plus left- and right
turn lanes southbound and a right-lane northbound onto the I-40 ramp.

u
The existing shoulders are grassed, with curb-and-gutter sections located at NC 54, McCrimmon
Parkway, Perimeter Park Drive, and from Slater Road to I-40.
1.2.2 Right-of-Way
The existing right-of-way width varies from 18 to 45 meters (60 to 148 feet) between NC 54 and
Slater Road and 45 to 85 meters (148 to 280 feet) from Slater Road to the I-40 ramps.
1.2.3 Horizontal and Vertical Alignment
The existing horizontal curves range from 268 m (60 30') to 873 m (20 00'). One curve just north
of Airtech Drive is substandard for the posted speed limit of 45 mph. Vertical grades range from
0.5% to 5.7%, with one substandard segment between NC 54 and Airtech Drive.
1.2.4 Speed Limit
The existing speed limit is 75 kilometers per hour (45 miles per hour).
1.2.5 Access Control
There is no control of access on SR 3015 (Airport Boulevard) in the project area.
1.2.6 Existing Development
Industrial and commercial development abuts the majority of SR 3015 (Airport Boulevard) frontage,
with approximately 20 residences also located along the corridor. Additional industrial parks and
commercial centers are proposed or under construction.
' 1.2.7 Intersecting Roads
Four at-grade signalized intersections are located on this segment of SR 3015 (Airport Boulevard):
' at NC 54, at Perimeter Park Drive, at Factory Shops Road / Aerial Center Parkway (the entrance to
Triangle Factory Shops southbound and Aerial Executive Center northbound), and at the I-40 ramps.
' Intersections with stop sign control are located along southbound SR 3015 (Airport Boulevard) at
the second Triangle Factory Shops entrance, Slater Road, SR 1640 (Sorrell Grove Church Road),
' SR 1706 (Watkins Road), and McCrimmon Parkway. Airtech Boulevard near NC 54 intersects with
northbound SR 3015 (Airport Boulevard) with stop sign control.

1.2.8 Drainage Structures
The following drainage structures are located in the project area:
• 1.8-meter (5.9-foot) pipe culvert south of McCrimmon Parkway.
• Double-barrel, 2.1-meter (10.5-foot) box culvert, north of SR 1640 (Sorrell Grove Church
Road).
• Triple-barrel, 3.2-meter box culvert at Factory Shops Road.
• Four smaller pipe culverts south of SR 1706 (Watkins Road), ranging in diameter between 38
and 76 centimeters (15 and 30 inches).
1.2.9 Utilities
Utilities have been identified based on field reconnaissance and recent design plans for a new water
' line (Bass, Nixon, & Kennedy, 1994). The following existing or proposed utilities are located along
SR 3015 (Airport Boulevard):

• An overhead electrical line runs the length of the project. Crossing at intersections and major
access roads, the line is on the west side of SR 3015 (Airport Boulevard) from NC 54 to just
north of the Emco Wheaton office building, the east side from Emco Wheaton to just south of
SR 1640 (Sorrell Grove Church Road), and then the west side from SR 1640 (Sorrell Grove
Church Road) to I-40.
• An underground gas line, owned by Public Service Company of NC, extends from Aerial Center
to SR 1640 (Sorrell Grove Church Road) beneath the northbound lane, and from SR 1640
(Sorrell Grove Church Road) to just north of the NC 54 intersection beneath the southbound lane
before crossing to the northbound side at the intersection.
• Overhead telephone and fiber optic lines run parallel along both sides of SR 3015 (Airport
Boulevard).
• An underground, 40-centimeter (16-inch) water line extends along the east side of SR 3015
(Airport Boulevard). Water service is provided by the Town of Morrisville.

' A new 40-centimeter (16-inch) water line is being constructed within the existing right-of-way
along the west side of the roadway.
' One sanitary sewer line, owned by the Town of Morrisville, crosses beneath SR 3015 (Airport
' Boulevard) south of SR 1640 (Sorrell Grove Church Road).
' Several large utility cabinets are located in the southwest corner of the SR 3015 (Airport
Boulevard) intersection with Factory Shops Road and in the southwest quadrant of the
' intersection with Perimeter Park Drive.

Chapter 2
Purpose and Need
' 2.1 Project Status
' The North Carolina Department of Transportation (NCDOT) proposes to widen and improve
SR 3015 (Airport Boulevard) from NC 54 to I-40 to five lanes with curb and gutter. The project is
listed in the 1997-2003 NCDOT Transportation Improvement Program (TIP) as U-3344. For the
major thoroughfare segment (McCrimmon Parkway to I-40), construction is scheduled to begin
' during Fiscal Year (FY) 1997. Right-of-way acquisition and construction of the remaining segment
(NC 54 to McCrimmon Parkway) are scheduled to begin in FY 2001 and 2003, respectively.
' 2.2 Accident Rates
The numbers and types of accidents experienced on a roadway can assist in determining the
' adequacy of the existing facility and the need for improvements. To determine accident rates, data
was analyzed from NCDOT's Crash Database for the period between January 1, 1992 and December
' 31, 1994. A total of 51 accidents were reported in the project area, including one fatal and 12 other
injury accidents. The accident rates and statewide averages are shown in Table 1.

' Of the 51 accidents reported on this section of SR 3015 (Airport Boulevard), 45.1% involved a rear
end collision from a slowdown, stop, or turn. The proposed widening is expected to reduce this type
' of accident, which is typical of a road operating near capacity through a developed area.
2.3 Traffic Volumes and Level of Service
' The existing (1995) annual average daily traffic (AADT) volumes on SR 3015 (Airport Boulevard)
range from 15,300 vehicles per day (VPD) between NC 54 and Perimeter Park to 26,800 VPD
between Factory Shops Road and I-40 (see Figure 3). Traffic volumes projected for design year
' 2020 are shown in Figure 4. The projected AADT volumes for the year 2020 are 31,800 and 39,000
VPD on the same segments. The projected volumes assume completion of the proposed
' McCrimmon Parkway and Perimeter Park Drive extensions.
A roadway's ability to handle traffic volumes is described in six levels of service (LOS), ranging
from A to F. At signalized intersections, the LOS is defined by stopped delay per vehicle (see
' Table 2) LOS A represents the best operating conditions with free flow and virtually no delay. LOS
F represents the worst operating conditions, with long queues of traffic and unacceptable delay at
intersections. LOS D is considered the lowest acceptable level of traffic service.

A traffic analysis was conducted based on the 1985 Highway Capacity Manual and the Highway
Capacity Software (HCS). Signalized intersections are a key indicator of a road's capacity problems.
During peak hours, the intersections on SR 3015 (Airport Boulevard) already experience
unacceptable congestion. As shown in Table 3, two of the intersections operate at LOS F with
oversaturated conditions. As volumes increase over the next 25 years, SR 3015 (Airport Boulevard)
at its current capacity will fail to handle the traffic. By increasing capacity with five lanes, the
signalized intersections will operate at LOS D in 2020.

An acceptable level of service will be provided through 2020 with the five-lane curb-and-gutter
roadway. Widening beyond five lanes would improve the level of service, but is not feasible due
to the existing and proposed development along SR 3015 (Airport Boulevard).
1 2.4 Benefits to the State, Region, and Community

F
This project will improve the level of traffic service and provide adequate capacity for the increasing
volumes of motorists using SR 3015 (Airport Boulevard). A safer, more efficient road will directly
benefit daily commuters who work along the route or who rely on it to reach other major
employment centers in the Research Triangle Park and nearby communities. Completion of the
project will fulfill local, county, and state planning objectives. With the anticipated growth in this
region, improvements to SR 3015 (Airport Boulevard) will be an important part of the future
7
C
r

' transportation network in the region, which will include the McCrimmon Parkway Extension, the
Raleigh Outer Loop, and expansion of the Raleigh-Durham International Airport facilities and
' interchange.
2.5 Summary of Project Need
Improvements to SR 3015 (Airport Boulevard) are needed to provide an acceptable level-of-service
' for projected traffic volumes. The proposed project is included in the NCDOT Transportation
Improvement Program and is compatible with the Greater Raleigh Urban Area Thoroughfare Plan.
' Certain types of accidents are expected to decrease in frequency with the improvements. In addition,
the increased capacity on SR 3015 (Airport Boulevard) will facilitate development of proposed
industrial and commercial areas.

Alternatives Considered
Through identification of environmental features and preliminary design, the most practicable
alternative for widening SR 3015 (Airport Boulevard) has been developed. The proposed alignment
is preliminary and will be further refined during final design. Additional alternatives were
considered, including the No-Build Alternative, postponing construction, and multi-modal options.
3.1 No Build Alternative
The No-Build Alternative provides for regular maintenance of the existing transportation routes and
systems. Examples of regular maintenance include patching and resurfacing roads, regrading
shoulders, and maintaining ditches. The "No Build" Alternative would avoid negative impacts to
the natural environment and land uses within the area of proposed construction. The proposed
project will not displace any residences or businesses and will have minimal impacts on natural
resources. The benefits of an improved SR 3015 (Airport Boulevard) outweigh these impacts by
improving traffic safety and convenience for local residents as well as for commercial and industrial
developments. These motorists depend on SR 3015 (Airport Boulevard) as a major thoroughfare.
The No Build Alternative would not provide any of these benefits. Furthermore, it would not fulfill
local and state transportation planning objectives.
3.2 Postponement of the Proposed Project
Postponing the proposed project has been considered as an alternative. By delaying improvements,
any costs, short-term inconvenience, and impacts on the natural environment would be delayed as
well. With current or proposed improvements at Raleigh-Durham International Airport, the Raleigh
Outer Loop, and the McCrimmon Parkway Extension, the volumes on SR 3015 (Airport Boulevard)
are expected to further increase. Delaying the improvements would negatively impact the existing
and proposed businesses along the road because of increased congestion and inconvenience. As

industrial and commercial development continues in and near the proposed right-of-way, costs and
impacts will increase if the project is delayed.
3.3 Transportation System Management
Transportation System Management (TSM) alternatives consist of improvements to highways
without major construction. TSM may include installing or optimizing signals, adding medians or
turn lanes, and other similar measures to improve traffic flow. The advantages of TSM alternatives
are their reduced impacts on the environment, lower costs, and shorter schedules to complete.
However, when projected traffic volumes exceed a roadway's capacity, TSM improvements alone
usually will not be able to provide an adequate level-of-service. Postponing construction would
increase impacts and costs.
The four intersections in the project area already are signalized with turn lanes. While adjusting the
signal timing or adding additional turn lanes could improve the existing level of traffic service, these
measures would not increase the capacity for SR 3015 (Airport Boulevard) to handle the projected
volumes in the future. In addition, turn lanes already exist at major commercial and industrial
entrances. Adding turn lanes or a center lane would not address the capacity problem for through
volumes. Therefore, TSM is not considered a viable alternative for the proposed project.
3.4 Multi-Modal
Mass transit alternatives are usually considered for major highway projects in urbanized areas. The
SR 3015 (Airport Boulevard) project area is heavily developed, but located in a fairly rural area.
Because most of the traffic is headed to the commercial/industrial developments or uses the road as
a commute route to other employment areas, mass transit would not relieve congestion to the point
of providing an acceptable level-of-service.
The Triangle Transit Authority (TTA) currently provides on-call shuttle service along SR 3015
(Airport Boulevard) with stops at the Enterprise Industrial Center, Perimeter Park, Aerial Center
10

C

Executive Park, and Triangle Factory Shops. The Town of Morrisville does not currently plan to
include any additional transit options in the project area.
Based on the Regional Transit Plan, the TTA requested consideration of the provision of additional
right-of-way along SR 3015 (Airport Boulevard) for use as a link in the proposed regional rail route
to connect NC 54 with the airport's future people mover system (see letter in Appendix A). Because
of the high level of development and access requirements along both- sides of the road, no additional
right-of-way for a rail line would be practicable or feasible as part of the proposed widening of SR
3015 (Airport Boulevard). A corridor parallel to the existing roadway but through less developed
right-of-way would be more suitable for rail service.
3.5 Build Alternative
The Build Alternative is the proposed widening of SR 3015 (Airport Boulevard) to five lanes with
curb and gutter from NC 54 to I-40. These improvements will provide an adequate level-of-service
for motorists through the year 2020. Both through traffic and turning traffic will move more
efficiently along the roadway. Disadvantages of the Build Alternative consist of its short-term
inconvenience during construction and impacts to the natural environment.
3.5.1 Alignments Considered
Alignments for the widening were considered during planning and functional design. The potential
alignments consisted of symmetrical widening, asymmetrical widening, and a combination of both.
To determine the preferred alignment, the following objectives were addressed:
• Avoid relocations of residences and businesses.
• Avoid the Sorrell Grove Community Cemetery.
• Improve horizontal and vertical alignments where practicable.
• Nfinimizeimpacts .to the natural environment,; including one forested wetland and three
,,q sang stream crossings.
The most practicable alignment was developed into - functional design plans (included in
Appendix B). As shown in the plans, much of the existing development abuts the roadway. The
11
n

u

L

0

I

alignment shown was determined to be the only practicable design to meet the project's objectives.
Most of the widening is symmetrical. From NC 54, new lanes are proposed on the west side to avoid
existing development at the intersection. The improvements shift to a symmetrical widening from
the Enterprise Industrial Center, minimizing impacts to parking and access at Perimeter Park;
avoiding the Sorrell Grove Community Cemetery, nearby residences, and office buildings under
construction; and improving the roadway's horizontal alignment. Where possible, the widening has
been located within the existing right-of-way. Curb and gutter is proposed rather than shoulders in
order to minimize right-of-way and easements required through this largely developed corridor.
3.5.2 Preferred Alternative
3.5.2.1 Type of Improvement
The Preferred Alternative is the widening of SR 3015 (Airport Boulevard) to five lanes between
NC 54 and I-40, as shown on the functional plans in Appendix B. The five-lane roadway will
consist of a 19-meter (62-foot) pavement with curb and gutter. Additional turn lanes will be
provided at the intersections with Factory Shops Road and Perimeter Park Drive.
3.5.2.2 Typical Section
As shown in Figure 5, the typical section consists of two through lanes in each direction with a
center turn lane. Curb and gutter will be added on both sides.
3.5.2.3 Right-of-Way
The acquisition of adequate right-of-way is proposed to contain the five-lane section. The right-of-
way width is to be approximately 30 meters (approximately 100 feet), with additional right-of-way
at intersections and construction easements to contain the proposed cross-section. The existing
right-of-way limits already are wide enough in several segments to contain the new construction.
The proposed project will require 0.99 hectare (2.45 acres) of additional right-of-way along the east
side of the roadway and 0.75 hectares (1.85 acres) along the west side. In addition, construction
easements will be required along 0.61 hectare (1.5 acres) on the east side of the roadway and 0.77
hectare (1.9 acres) on the west side.

3.5.2.4 Bikeways/Sidewalks
SR 3015 (Airport Boulevard) serves commuting traffic for the industrial and commercial employers
along the corridor. Because of the many access points on both sides of the roadway, bicycle and
pedestrian uses are limited. No pedestrian or bicycle facilities will be impacted or are planned as
part of the improvements. Aviation Parkway, which runs parallel to SR 3015 (Airport Boulevard)
from NC 54 to I-40, is part of the North Carolina Bike Route (US 1) that already serves the bicycling
needs in the vicinity.
3.5.2.5 Proposed Design Speed
The design speed for SR 3015 (Airport Boulevard) will be 80 kilometers per hour (50 miles per
hour). The posted speed limit will be 45 miles per hour.
3.5.2.6 Access Control
There is currently no control of access along SR 3015 (Airport Boulevard), and the proposed project
will not include any access control.
3.5.2.7 Intersection Treatment
All intersections will be at-grade, with signalized control remaining at NC 54, Perimeter Park Drive,
Factory Shops Road, and the I-40 ramps. Other intersections will have stop sign control. The future
construction of the McCrimmon Parkway Extension may require signalization at existing
McCrimmon Parkway and SR 3015 (Airport Boulevard).
3.5.2.8 Utilities
As described in Sections 1.2.9 and 4.5, existing utilities are located in the project area. The proposed
project will require relocation of overhead electrical, telephone, and fiber optic lines as well as a gas
line and several street lights, fire hydrants, poles, and utility boxes. Coordination with the utility
providers will continue throughout design and construction to minimize disruption. These utility
impacts are considered to be in the medium level.
3.5.2.9 Permits
Section 401 of the Clean Water Act requires each state to certify that state water quality standards
will not be violated for activities that: (1) involve issuance of a federal permit or license or (2)
13

n
require discharges into "waters of the United States." Accordingly, 401 Water Quality Certification
will be required by the N.C. Department of Environment, Health, and Natural Resources--Division
of Environmental Management. In addition, Section 404 of the Clean Water Act requires permitting
from the Corps of Engineers for activities that encroach into jurisdictional wetlands or "waters of
the United States." Because of the size (0.014 hectare) of the wetland area to be impacted by the
proposed project, no permit is anticipated to be required by the Corps of Engineers. A letter of
notification will be sent to the Corps for approval. If a permit is required, either Nationwide Permit
14, Roadway Crossings, or Nationwide Permit 26, Headwaters and Isolated Waters Discharges, will
likely be applicable. The final permit decision will be at the discretion of the Corps of Engineers.
3.5.2.10 Cost Estimates
Construction of the proposed project is scheduled to begin in Fiscal Year 1997. The estimated cost
is $5.15 million including $2.15 million for right-of-way and $3.0 million for construction. The
estimated total cost in the 1997-2003 TIP is $3.4 million.
3.4.2.11 Traffic Analysis
A traffic analysis was conducted based on the 1985 Highway Capacity Manual and the Highway
Capacity Software (HCS). Signalized intersections are a key indicator of a road's capacity problems.
During peak hours, the intersections on SR 3015 (Airport Boulevard) already experience
unacceptable congestion. As volumes increase over the next 25 years, SR 3015 (Airport Boulevard)
at its current capacity will fail to handle the traffic. By increasing capacity with the Preferred
Alternative, the signalized intersections will operate at LOS D in 2020.

' Chapter 4
Social and Environmental Consequences
4.1 Land Use Impacts
' The existing land uses along SR 3015 (Airport Boulevard) are mostly industrial and commercial (see
Figure 6), with approximately 20 single-family residences scattered between these uses.
' The proposed project will not adversely affect existing or proposed land uses. In the adopted Town
' of Morrisville Land Use Study (1989), the undeveloped land adjacent to SR 3015 (Airport
Boulevard) is dedicated for industrial and commercial uses. This plan serves as a framework for
' land use and rezoning decisions. Additional developments are planned or under construction,
totalling more than 100 acres for retail, industrial, and distribution. Adding the lanes to SR 3015
' (Airport Boulevard) will improve access as the employment centers further develop in the area.
4.2 Neighborhood Impacts

The proposed widening of SR 3015 (Airport Boulevard) will not cut off any neighborhoods or local
streets. Overall travel efficiency will be improved, and the improvements will be integrated into the
current and proposed transportation network. Access will not be controlled along the roadway.
There are no established communities within the project area that would be affected by the proposed
widening.
In compliance with Executive Order 12898 (Federal Actions to Address Environmental Justice in
Minority Populations and Low Income Populations), 1990 Census data have been reviewed to
determine whether any minority or low-income populations were receiving disproportionately high
and adverse human health or environmental impacts as a result of this project. No minority or low-
income populations will be disproportionately affected by direct or indirect impacts of the proposed
project. Of the 2,911 residents located within Census tract 536.98 (the smallest tract covering the
project area), 15.3% are non-white, 2.3% are disabled from working (ages 16-64), and 6.0% are

' living below the poverty level. By comparison, the averages for Wake County are 25.9% non-
white, 1.7 % disabled from working, and 7.1% below the poverty level. Approximately 20
residences are located along SR 3015 (Airport Boulevard).
4.3 Relocation Impacts
Based on field reconnaissance and verification by NCDOT right-of-way staff (see relocation report
' in Appendix E), the proposed project will not require relocation of any residences or businesses.
Three dilapidated and unoccupied buildings may be removed.
4.4 Community Facilities
The Sorrell Grove Community Cemetery is located just west of SR 3015 (Airport Boulevard), south
' of SR 1640 (Sorrell Grove Church Road). The proposed widening has been designed to avoid this
cemetery. Sorrell Grove Baptist Church is located west of SR 3015 (Airport Boulevard) and will
t be avoided by the project. No other community facilities are located in the project area.
4.6 Utilities
' Overhead electrical, telephone, and fiber optic lines will require relocation. Several street lights and
fire hydrants located along SR 3015 (Airport Boulevard) will be relocated. Some utility poles are
' located outside the proposed construction and right-of-way limits, while others will have to be
moved. In addition, the gas line and several utility boxes will require relocation. Based on current
' survey data, the water and sewer lines will be able to remain in place. NCDOT will coordinate with
the appropriate utility companies prior to construction to minimize interruptions.

4.6 Economic Impact
1
SR 3015 (Airport Boulevard) is used primarily by commuters to the business parks and other
' employment centers in the area, by shoppers, and by travelers and employees at Raleigh-Durham
International Airport. Several new business parks are proposed or under construction as well.

Improving access and the road's capacity will have a positive impact on the local economy. The
flow of goods and services will be improved to and from the airport and other locations in the
Research Triangle region. Users of the proposed widened roadway will benefit from reduced travel
time and reduced congestion.
4.7 Historic Architectural and Archaeological Resources
7

F
r

u

This project is subject to review pursuant to North Carolina General Statute 121-12(a) which
requires that if a state action will have an adverse effect upon a property listed in the National
Register of Historic Places, the North Carolina Historical Commission will be given an opportunity
to comment.
Documentation from the Deputy State Historic Preservation Officer (see Appendix A) recommends
that no historic structure surveying nor archaeological investigation be conducted because a file
search by the N.C. Department of Cultural Resources revealed no known sites already listed in the
National Register. The proposed widening will occur along the existing roadway where much of
the ground has been disturbed previously. The project will have no effect on historic architectural
or archaeological resources. Based upon the recommendation of the Deputy State Historic
Preservation Officer, no historic structure nor archaeological survey will be conducted with the
project.
4.8 Air Quality
The U. S. Environmental Protection Agency (EPA) has identified six pollutants for tracking air
quality. These six pollutants are: particulate matter (PM-10), sulfur dioxide (SOA nitrogen dioxide
(NOA carbon monoxide (CO), ozone (03), and lead (Pb). Mobile sources (principally vehicular
traffic) are linked to the emission of carbon monoxide and, to a lesser extent, nitrogen dioxide and
ozone. Recent nationwide estimates indicate that more than 50 percent of all CO emissions are from
mobile sources. Particulate matter, lead, and sulfur dioxide emissions are generally associated with
stationary sources and industrial activities.
17

CO is the most commonly occurring air pollutant generated by mobile sources. It is a colorless gas
produced from incomplete combustion of carbon-containing fuel. CO is a potentially fatal gas that
affects the oxygen-carrying capacity of blood. At low concentrations, mental function, vision, and
alertness are affected.
Ambient air quality is determined by measuring ambient pollutant concentrations and comparing
the concentrations to the corresponding standard. "Ambient air" is defined by EPA as "that portion
of the atmosphere, external to buildings, to which the general public has access." The EPA has
established National Ambient Air Quality Standards (NAAQS) for the six previously identified
pollutants; PM-10, CO, 03, SOz, NOz, and Pb. The ambient air quality standards are classified as
primary standards, secondary standards, or both. The primary standards were established allowing
an adequate margin of safety for protection of public health. Secondary standards were established
with an adequate margin of safety to protect the public welfare from adverse effects associated with
pollutants in the ambient air.
In protecting public welfare, air pollution effects on the following are considered; soils, water,
crops, vegetation, man-made materials, animals, wildlife, weather, visibility, climate, property,
transportation, economy, personal comfort, and well-being. The scientific criteria upon which the
standards are based are periodically reviewed by EPA, and the standards are re-established or
changed based upon the findings. The current national primary and secondary ambient air quality
standards are summarized in Table 4.
Monitoring of the pollutants, except Pb, is performed statewide by the North Carolina Division of
Environmental Management (NCDEM). When standards are exceeded, an area is labeled as non-
attainment for that pollutant. Wake County recently has been classified as a maintenance area. The
dates of redesignation to a maintenance area are June 17, 1994 for 03 and September 18, 1995 for
CO.

The project is located in Wake County, which is within the Raleigh-Durham nonattainment area for
ozone (03) and carbon monoxide (CO) as defined by the EPA. The 1990 Clean Air Act
Amendments (CAAA) designated these areas as "moderate" nonattainment area for 03 and CO.
However, due to improved monitoring data, these areas were redesignated as "maintenance" for 03
on June 17, 1994, and "maintenance" for CO on September 18, 1995. Section 176(c) of the CAAA
requires that transportation plans, programs, and projects conform to the intent of the state air quality
implementation plan (SIP). The current SIP does not contain any transportation control measures
for Wake County. The Capital Area 1995 Transportation Improvement Program (TIP) has been
determined to conform to the intent of the SIP. The MPO approval date for the TIP is July 20, 1995.
The USDOT approval date of the TIP is October 4, 1995. The current conformity determination is
consistent with the final conformity rule found in 40 CFR Part 51. There have been no significant
changes in the projects's design concept or scope, as used in the conformity analyses.
The most prevalent pollutant emitted from motor vehicles is CO. For this reason, the analyses
presented are concerned with determining the projected 2020 CO levels in the vicinity of the project.
19

To determine the CO concentration at a receptor, two concentration components must be used: local
and background. The local component is predicted from dispersion modeling and is due to CO
emissions from motor vehicles operating near the receptor locations. The background component
is the ambient CO level, which the Air Quality Section of NCDEM estimated to be 1.8 ppm for the
Durham/Wake County region which includes the project area. These two components were added
together to determine the total CO concentration for comparison to the NAAQS.
Areas with high traffic volumes are most likely to generate the highest levels of CO. In determining
the air quality impact of the proposed project, the intersection with the highest projected volumes
of traffic was evaluated. The intersection of SR 3015 (Airport Boulevard) and Factory Shops Road
is anticipated to have the highest CO levels due to high traffic volumes, congestion, and the presence
of vehicles idling at these proposed signalized intersections.
At this intersection, the line source computer model CAL3QHC was used to predict the local CO
concentration components. The CAL3QHC model is a dispersion computer model developed for
EPA. Based on the assumption that vehicles at an intersection are either in motion or in an idling
state, the program is designed to predict air pollution levels by combining emissions from both
moving and idling vehicles.
CAL3QHC uses emission factors generated by EPA's approved model MOBILE 5A. The emission
factors used were taken from Tables 3.2 and 3.3 in Guidelines for Evaluating the Air Quality
Impacts of Transportation Facilities, written by the North Carolina Department of Environmental
Management Air Quality Section (see Appendix C for factors).
As stated earlier, the intersection with the heaviest projected traffic volumes was evaluated. A total
of 20 different receptors (5 in each quadrant) were analyzed to compare the air quality impact of the
proposed SR 3015 (Airport Boulevard) improvements. Table 5 summarizes the results of the air
quality analysis.

' In 2020, the maximum one-hour CO concentration at the intersection of SR 3015 (Airport
Boulevard) and Factory Shops Road is predicted to be 11.5 ppm as shown in Table 5. This was
' based on 1 degree wind angle intervals.
' Comparison of the predicted CO concentrations with the NAAQS indicates that no violations of the
one-hour CO standard of 35 ppm will occur. Using a persistence factor of 0.6, the eight-hour
average is 6.9, below the eight-hour standard (9.0). Therefore, the proposed widening will not create
an accedence of the NAAQS.
4.9 Noise
Traffic noise results from the vehicle's engine, exhaust, and drive train, and from the tire-roadway
' interaction. The actual magnitude of sound is caused by short-duration fluctuations in atmospheric
pressure. These fluctuations are called sound pressures. Since the range of sound pressures varies
' greatly, a logarithmic relationship is used to reference sound pressures to a common pressure. This
relationship is defined as the sound pressure level and is measured in decibels (dB). The decibel is
often modified by frequency -weighting curves (A, B, C, or D). Vehicle noise levels are commonly
21

r

F
C
L
n

1
J

modified by the A-weighting curve which correlates very well with human response to noise. Sound
levels using the A-weighting curve are expressed in dBA.
Sound pressure levels in this report are expressed as the hourly Leq, or equivalent sound level, which
is the level in dBA of constant sound that would contain the same acoustic energy in an hour as the
actual sound, which varies considerably over time. In other words, the fluctuating sound levels of
traffic noise are represented in terms of a steady noise level with the same energy content.
To determine if highway noise levels are compatible with various land uses, the NCDOT has
developed noise abatement criteria and procedures in accordance with Title 23 Code of Federal
Regulations (CFR), Part 772, U.S. Department of Transportation, Federal Highway Administration
(FHWA), Procedures for Abatement of Highway Traffic Noise and Construction Noise. A summary
of the FHWA Noise Abatement Criteria (NAC) for various land uses is presented in Table 6.
One factor in considering traffic noise mitigation involves future noise levels that either approach
or exceed the criteria levels for each activity category. Approach is defined as with 1 dBA of the
criteria. Title 23 CFR, Section 772.11 (a) states, "In determining and abating traffic noise impacts,
primary consideration is to be given to exterior area. Abatement will usually be necessary only
where frequent human use occurs and a lowered noise level would be of benefit." Most of the
activity in the corridor is Category C (developed landsibusinesses) with some Category B
(residences). No Category A activity occurs in the corridor.
Another factor in considering traffic mitigation is the difference between the existing noise and the
project noise level. If the projected noise level results in a substantial noise increase then mitigation
may be warranted. A substantial increase is defined as a 10 dBA increase if the existing noise level
is greater than 50 dBA and a 15 dBA increase if the existing noise level is less than or equal to 50
dBA.

west of the SR 1640 (Sorrell Grove Church Road) and SR 3015 (Airport Boulevard) intersection.
The noise level was 66 dBA at the second site, located between a house and a mobile home on SR
3015 (Airport Boulevard), between NC 54 and McCrimmon Parkway. The noise level at the third
site, beside Days Inn just north of Slater Road, was 67 dBA. Based on these observations, the
existing noise level is relatively high, approximately 66 dBA.
The extent of the 66 dBA noise level contour is used to assess the exposure impacts of residential
land uses since receptors located within the 66 dBA noise level contour approach or exceed the
' FHWA NAC for Category B land use activities. The extent of the 71 dBA noise level contour is
used to assess the exposure impacts of Category C land uses. Furthermore, this information is
' provided to assist local authorities in exercising land use control over the remaining undeveloped
lands adjacent to the roadway and to prevent further development of incompatible activities and land
' uses. Table 7 indicates the maximum extent of the 66 dBA and 71 dBA contour lines and the
i
predicted noise levels at 15, 31, 61, 122, and 244 meters (50, 100, 200, 400, and 800 feet) from the
23
k

' project centerline. The noise contours, based on project 2020 traffic volumes, were determined
using the FHWA approved noise model STAMINA 2.0.

' The 66 dBA noise contour line is located 64.6 meters from the centerline in Segment 1, 55.9 meters
in Segment 2, 67.0 meters in Segment 3 and 55.0 in Segment 4. The proposed right-of-way width
' for the roadway is 42.7 meters (140 feet). Based on the proposed typical section, the 66 dBA
contour line extends between 33.7 meters and 45.7 meters from the edge of the right-of-way. The
' 71 dBA contour line extends between 6.1 and 10.7 meters from the edge of the right-of-way. Noise
levels at 19 residences and one hotel are projected to exceed the 66 dBA FHWA NAC. Three
business sites at or near NC 54 (one abandoned) are projected to exceed the 71 dBA FHWA NAC.
Based on the projected traffic volumes and because the existing noise environment is relatively high
' (66 dBA), none of the receptors are expected to experience a substantial noise increase.
Because the FHWA NAC will be exceeded at some receptors, noise abatement measures were

r
evaluated. The following measures were reviewed:
24

• Alignment shifts
• Traffic system management measures
• Vegetative barriers and earthen berms
• Acquisition of property
• Noise barriers
Alignment shifts involve adjusting the horizontal or vertical alignment of the proposed
improvements in such a way as to minimize impacts and costs. For noise abatement, alignment
selection is primarily a matter of siting the roadway at a sufficient distance from noise sensitive
areas. For SR 3015 (Airport Boulevard), changes in the vertical alignment of the proposed
improvements were not considered applicable. Shifting the horizontal alignment is not considered
to be a viable alternative, since noise-sensitive areas are found on both sides of the proposed
roadway.
Traffic system management measures which limit vehicle type, speed, volume, and time of
operations were not considered appropriate for noise abatement due to their effect on the capacity
and level of service on the proposed roadway. Typically, a reduction in speed limit of 10 MPH
would result in a noise level reduction of approximately 1 to 2 dBA. Because most people cannot
detect a noise reduction of up to 3 dBA and because reducing the speed limit would reduce roadway
capacity and increase user cost, it is not considered a viable noise abatement measure.
The use of vegetation for noise barriers is not considered to be effective in the actual reduction of
noise levels for this project, due to the substantial amount of right-of-way necessary to make
vegetative barriers effective. While earthen berms generally are more cost effective noise
attenuation than other barrier materials, they are limited by right-of-way and other engineering
considerations (drainage, access, future development). Accordingly, berms are not feasible for this
project, where right-of-way is extremely constricted.
The acquisition of property in order to provide buffer zones to minimize noise impacts is not
considered to be a feasible noise abatement measure for this project. The cost to acquire impacted
residences for buffer zones would exceed the NCDOT's abatement threshold of $25,000 per
residential unit.
25

One of the most effective noise abatement measures is the proper use of land-use controls to
minimize future impacts. Local jurisdictions with zoning control should use the information
contained in the final noise evaluation to develop policies to limit the growth of noise-sensitive land
uses adjacent to the freeway. The policies could include setback requirements, building codes, and
zoning.
Noise barriers can be an effective measure for noise abatement. However, several characteristics
of SR 3015 (Airport Boulevard) make noise barriers an unrealistic approach. NCDOT Noise
Abatement guidelines indicate that noise barriers are not reasonable for the scattered or isolated
residences and impacted business along the corridor. Due to aircraft and other noise sources in the
area, noise barriers are not reasonable for lowering the overall noise level. Therefore, noise barriers
are not recommended as a noise abatement measure.
4.10 Natural Resources
Based on literature reviews, aerial photograph interpretation, and field reconnaissance, the existing
natural environment and potential impacts of the project were assessed. The results are detailed in
the Natural Resources Technical Memorandum (December 1995) and summarized in the following
sections.
4.10.1 Terrestrial Plant Communities
The distribution of plant communities in a landscape is the result of topographic positioning,
climate, soil characteristics, hydrologic influence, and past and present land-use practices. The
majority of the land adjacent to SR 3015 (Airport Boulevard) has been developed or is being cleared
for development.
Through aerial photograph interpretation and field visits in September 1995, three vegetative
communities were identified in the area. These communities include mixed pine/ hardwood forest,
successional field, and urban/disturbed. Figure 6 identifies plant communities in the project area.
Mixed Pine/Hardwood Forest - Mixed pine/hardwood forest communities occur in fragments
throughout the project area. The southwestern portion, closest to NC 54, contains the largest areas
26
P
r

n

of undeveloped land. Mixed pine/hardwood communities are common in the Piedmont North
Carolina landscape. Plant species found here include an overstory of loblolly pine (Pinus taeda),
pignut hickory (Carya glabra), and various oak species (Quercus spp.). The understory includes
saplings of the overstory species as well as flowering dogwood (Corpus Florida). Shrubs, vines, and
herbaceous groundcover are limited in this area. Species that occur include viburnums (Viburnum
spp.), greenbriers (Smilax spp.), poison ivy (Toxicodendron radicans), and panic grasses (Panicum
spp.). Approximately 1.01 hectares (2.50 acres) of mixed pine/hardwood forest would be impacted
by the proposed project.
Successional Field - A small amount of land within the project area is in the early stages of
succession. In Piedmont North Carolina, old field succession progresses from the time cultivation
of the land stops and annual plants cover the bare field. If the land is not disturbed, the transition
continues until a mature hardwood forest is present.
The successional fields seen in the project area are most likely in the early years of abandonment.
This judgement is based on the presence of grasses and sedges such as ragweed (Ambrosia
artemisiifolia), goldenrod (Solidago spp.), and broomsedge (Andropogon spp.), which are
characteristic early successional species.
According to preliminary design plans, this successional area will not be impacted by the proposed
project.
Urban/Disturbed - The majority of the land in the project area would be classified as
urban/disturbed, which includes commercial, office, and industrial developments, residential areas,
utility corridors, existing roads, and other natural areas that have been cleared for development.
Most of the vegetation in these areas has been removed or altered by human activity. Maintained
grasses and ornamental landscape plantings adjacent to residential houses, business and industrial
areas, and roadside rights-of-way are included in this category. Wetland areas that have been
permitted for fill and are currently being developed are also included in this category.
Approximately 3.18 hectares (7.84 acres) of urban/disturbed land will be impacted by the proposed
project.

Clearing, grading, and creating borrow areas are the primary actions that would modify vegetative
communities during the proposed widening of SR 3015 (Airport Boulevard). The impacts to the
natural communities have been quantified, as shown in Table 8, based on proposed right-of-way
width or construction limits, whichever is wider. The impact areas were quantified by sketching
habitat boundaries on 1:2,400 (1" = 200') scale aerial photography containing the limits of proposed
right-of-way and then planimetering within the boundaries.
Table 8
Impacts to Plant Communities
Community Type Area of Impact (ha/ac)
Mixed Pine/Hardwood Forest 1.01 ha / 2.50 ac
Urban/Disturbed 3.18 ha / 7.84 ac
4.10.2 Wildlife
The plant communities in the project area provide food, shelter, and nesting resources for a diverse
wildlife population. The mixed pine/hardwood forests are particularly good wildlife habitat when
located adjacent to agricultural fields, successional areas, and open fields. During field visits,
however, no animals were observed. Raccoon (Procyon lotor) tracks were seen along the banks of
a tributary.
Animals commonly found in mixed pine/hardwood forests include mammal species such as the grey
squirrel (Sciurus carolinensis), white-tailed deer (Odocoileus virginianus), eastern cottontail
(Sylvilagus floridanus), raccoon, and opossum (Didelphis marsupialis). Nesting bird species
typically occurring in these areas include the wood thrush (Hylocichila mustelina), red-eye vireo
(Vireo olivaceus), tufted titmouse (Pavus bicolor), and pine warbler (Dendroica pinus). Other
common bird species include the northern cardinal (Cardinal cardinalis), common flicker (Colaptes
auratus), bluejay (Cyanocitta cristata), downy woodpecker (Picoides pubescens), and common crow
(Corvus brachyrhynchos).

Streams in the project vicinity may provide habitat for fish, amphibian, and invertebrate species.
The distribution of aquatic organisms depends on stream characteristics such as flow, riffles and
pools, substrate type, and water quality. No fish, however, were seen in streams within the project
area. The flow, depth, and other characteristics of these stream reaches are not suited to diverse fish
life.
Fish species that may occur downstream of the project area and in Lake Crabtree include catfish
(ktalurus spp.), large mouth bass (Micropterus salmoides), bluegill and other sunfish species
(Lepomis spp.), carp (Cyprinus carpio), and various other minnow species (Gambusia afnis,
Notropis spp., and Catosomus spp.).
Amphibian species such as the bullfrog (Rana catesbeiana), green frog (R clamitans), and American
toad (Bufo americanus), depend on waters of creeks, streams, and ponds in which they either
permanently reside or use for breeding habitat.
Reptile species such as snapping turtles (Chelydra serpentina), sliders (Chrysemys spp.), and water
snakes (Nerodia spp.) rely upon aquatic habitat for food and shelter.
Impacts to terrestrial and aquatic wildlife will be minimal due to the disturbed nature of the project
area.
4.10.3 Habitat Reduction
Habitat fragmentation occurs when parcels of habitat are isolated and made less suitable for wildlife.
This impact decreases the species richness and diversity within the area. The degree of impact
depends on the size and isolation of the parcels being fragmented and the sensitivity of the species.
Plant and animal species with large home range requirements, specific microhabitat requirements,
and poor dispersal abilities are most affected by habitat fragmentation.
As discussed in Section 4.10.1, many of the forest tracts within the project area have already been
fragmented by residential and commercial development. Fragmentation will not be increased.

4.10.4 Protected Species
Throughout the United States, rare plant and animal species are protected by federal and state laws.
The Endangered Species Act of 1973 (16 U.S.C. 1531-1943) mandates that federal agencies ensure
that any actions authorized, funded, or carried out by that agency do not jeopardize the "continued
existence" of listed species or result in the destruction or adverse modification of critical habitat (16
U.S.C. 1536). Proposed species are offered "limited protection" under Section 7 (A)(3) of the
Endangered Species Act of 1975, as amended by Congress in 1988. North Carolina laws grant
protection to rare plants and animals that are endemic to the state or whose populations are in severe
decline (LACES Act 6.5.113-351 to 113.337 and N.C. Plant Protection and Conservation Act of
1979). Species discussed here are those listed by USFWS for Wake County as of April 1, 1996.
The methodology used to identify potential habitat for and existence of federal and state listed
candidate species for Wake County included a literature review, coordination with the U.S. Fish and
Wildlife Service (USFWS) and the N.C. Natural Heritage Program, and field reconnaissance in the
project area.
A list of rare or protected species known to occur in Wake County is included in Appendix D.
4.10.4.1 Federally Listed Species
Federally protected species with either endangered (E), threatened (T), or proposed threatened or
endangered (PT or PE) status receive protection under the Endangered Species Act. Written
correspondence (see Appendix A) from the USFWS and N.C. Natural Heritage Program states that
there are no records of known rare species, high quality natural communities, or significant natural
areas occurring at the SR 3015 (Airport Boulevard) widening project site or within a one-mile radius
of the site. While no systematic inventory has been done in the project area, the following species
are known to occur in Wake County and are federally listed as either threatened or endangered.

Though no suitable bald eagle habitat exists in the project area, the sighting of an eagle
approximately 1.5 miles away prompted further investigation. Project biologists conducted
background research on the bald eagle and its habitat, spoke with personnel at the N.C. Natural
Heritage Program and USFWS, and revisited the project area to look specifically for bald eagle
habitat. Typical bald eagle nesting habitat requires old-growth stands of hardwood trees and a large
body of water. These two requirements are critical as bald eagles's nests are extremely large
structures that need sturdy trees, and 60 to 90 percent of an eagle's diet is fish. The SR 3015 (Airport
Boulevard) project area contains neither of these elements. Thus, it is unlikely that any bald eagles
nest or forage in the project area. The bald eagle that was seen may have come from or been in
transit to Jordan Lake, which is a protected nesting area. The proposed project will have no effect
on the bald eagle.
Red-cockaded woodpecker habitat consists of mature pine forests. Though groups of red-cockaded
woodpeckers have been known to support themselves on fewer acres, most need an average of 200 acres.
None of the plant communities in the SR 3015 (Airport Boulevard) project area would provide suitable
habitat for red-cockaded woodpeckers. According to the USFWS and the N.C. Natural Heritage
Program, no red-cockaded woodpeckers are known to be in the project area. The proposed project will
have no effect on the red-cockaded woodpecker.
The dwarf wedge mussel is a small, freshwater mollusk with a brown or yellowish brown shell. Its
habitat is sand, muddy sand, and gravel substrate in large rivers and small creeks where the current is
slow to moderate and where there is little silt. According to the USFWS (1994) the dwarf wedge mussel
31

J

i

occurs in only 25 stream reaches along the Atlantic Coast from New Brunswick, Canada to North
Carolina. None of those streams are within the project area. The streams in the project area, especially
Stirrup Iron Creek and its unnamed tributary, have been affected by adjacent land use and development,
resulting in siltation. Discussions with a mussel specialist (John Alderman, 1996) indicated that this
perennial stream does not support mussel fauna. No mussel fauna was seen in these waters during field
investigation.
Water quality in the unnamed tributaries to Crabtree Creek may be suitable to support mussel fauna. The
intermittent nature of these streams, however, makes it unlikely that they could support mussel fauna.
A survey for mussel species in the unnamed tributaries to Crabtree Creek was done on March 14, 1996.
Environmental scientists examined both streams. The first, closest to NC 54, is an intermittent stream
that is less than 0.6 meters (2 feet) wide and is not actively flowing. No mussel fauna or evidence of such
was present. The second tributary is also an intermittent waterway. This stream is 1 to 1.5 meters (3
to 5 feet) wide with moderately flowing water that is 150 to 230 millimeters (6 to 9 inches) deep. This
stream was walked from its outflow adjacent to SR 3015 (Airport Boulevard) to approximately 100
meters (300 feet) downstream; no mussel fauna or evidence of such was present. No effect to the dwarf
wedge mussel will occur as a result of the proposed project.
Michaux's sumac is a nonpoisonous, low-growing dioecious shrub in the Cashew Family. This species
was historically endemic to the inner Coastal Plain and lower Piedmont of North Carolina, South
Carolina, and Georgia. According to the N.C. Natural Heritage Program, one occurrence of Michaux's
sumac has been documented in Wake County on land owned by the City of Raleigh. There are no known
occurrences of Michaux's sumac in the project area.
Suitable Piedmont habitat for Michaux's sumac includes sandy, acidic soils and clayey circumneutral
soils on dry, upland, open wooded sites, and it is dependent on some form of disturbance to maintain
open area. In the past, areas with naturally occurring fires were the most likely habitat. Today,
many of the known occurrences are in disturbed areas such as highway and railroad rights-of-way,
edges of cultivated fields, and other cleared lands. In the Piedmont, however, fire suppression has
taken a heavy toll on the plant. The SR 3015 (Airport Boulevard) project area includes suitable
habitat for Michaux's sumac. The best time to identify the plant is during its peak growing season
32

' from June to September. The plant also is easily identified during winter by its distinctive,
pubescent woody stem.

the species will occur as a result of the proposed roadway widening.

Federal species of concern (FSC) are those which may in the future be considered for listing as
' endangered or threatened. These species are not legally protected under the Endangered Species Act
or any of its provisions until they are formally proposed or listed as endangered or threatened. No
' further investigations are recommended at this time for these species. The following are FSC for

4.10.5 Wetlands
Wetlands are defined by the U.S. Army Corps of Engineers (COE) (33CFR 328.3) and the U.S.
Environmental Protection Agency (EPA) (40 CFR230.3) as:
34

F
L

"those areas that are inundated or saturated by surface or ground water at a frequency and
duration sufficient to support, and that under normal circumstances do support, a prevalence
of vegetation typically adapted for life in saturated soil conditions. Wetlands generally
include swamps, marshes, bogs, and similar areas."
In accordance with this definition, wetlands must possess three essential parameters: hydrophytic
vegetation, hydric soils, and evidence of hydrology (COE Wetlands Delineation Man"60".01
Besides providing valuable habitat for a diverse number of plant and animal species, wetlands also
control floodwaters and erosion, replenish groundwater, filter contaminants and excess nutrients
from runoff, and protect water supplies.
Section 404 of the Clean Water Act requires regulation of the disposal of dredged or fill material
into "waters of the United States," which are both deepwater aquatic habitats and special aquatic
sites, including wetlands (COE Wetlands Delineation Manual, 1987). The principal administrative
agency of the Clean Water Act is the U.S. Environmental Protection Agency (EPA). The COE has
the major responsibility of implementing, permitting, and enforcing provisions of the Act in
cooperation with the EPA and USFWS. Executive Order 11990 requires that new construction in
wetlands be avoided to the extent possible and that all practicable measures be taken to minimize
or mitigate impacts to wetlands.
The location, extent, and quality of potential wetlands in the SR 3015 (Airport Boulevard) project
area were investigated in September 1995. Wetland information was obtained through:
• Review of National Wetland Inventory (NWI) maps and U.S. Geological Survey (USGS)
topographic maps of the area (Cary, N.C. quadrangle).
• Review of the Soil Conservation Service Soil Survey of Wake County.
• Review of COE permit files for wetlands in the project area.
• Consultation with COE personnel.
• Field inspections.
35

The NWI map for the project area showed some palustrine forested wetland areas along the banks
of Stirrup Iron Creek and an unnamed tributary of Stirrup Iron Creek. These areas are shown in
' Figure 6. A site visit on September 26, 1995 confirmed these areas as potential wetlands, but they
were no longer forested and construction on these sites was in progress. The COE was contacted
for information regarding wetland permits in the project area. Table 11 summarizes the location and
extent of disturbance for each of the permitted areas.

hydric soil parameters. The vegetation in this area consists of black willow (Salix nigra), red maple
(Acer rubrum), sweetgum (Liquidambar styraciflua), white oak (Quercus alba), pignut hickory
(Carya glabra), and common greenbrier (Smilax rotundifolia).
On November 29, 1995, wetland scientists delineated the wetland area following COE procedures
as outlined in the 1987 Wetlands Delineation Manual. That same day, a representative from the
Wake County COE field office confirmed the wetland boundary. To complete the delineation and
proceed with permitting, data forms will be submitted to the COE. The wetland area is
approximately 0.09 ha (0.22 ac) based on a survey of the boundaries.
Because of its location near the existing roadway, the wetland will not be completely avoidable
without compromising the design criteria. Based on preliminary plans, impacts to 0.014 ha (0.03
ac) of this wetland will not be avoidable when this section of the SR 3015 (Airport Boulevard)
widening is constructed. To minimize the impact, the alignment has been shifted while still avoiding
an existing business across the street and maintaining acceptable geometrics.
A letter of notification will be submitted to the COE concerning the impact. Any required mitigation
will be addressed based on final design plans.
The previously permitted wetland areas have been included as part of the urban/disturbed areas for
impact calculations.
4.10.6 Water Quality
Water quality for streams in the SR 3015 (Airport Boulevard) vicinity has been determined and
documented by the North Carolina Division of Environment Management (N.C. DEM, 1993).
lass C waters are
defined as suitable for aquatic life propagation and survival, fishing, wildlife, secondary recreation,
and agriculture. re suitable
for all uses identified for Class C waters plus primary recreation. All four stream systems also carry
an additional classification of nutrient sensitive waters (NSW), which means that nutrient inputs are
limited by law.

Benthic Macroinvertebrate Ambient Network (BMAN) Monitoring Survey is another approach to
assess water quality using biological indicators. BMAN results are available for certain water basins
throughout North Carolina and are useful for determining long-term changes in water quality. The
classification system uses ratings of poor to excellent.
ite near I-40, the northeastern border of the project area was rated fair. A site near
NC 54, the southwestern border, was rated fair in March 1988 and poor in August of the same year.
No BMAN monitoring sites are documented for Stirrup Iron Creek.
4.10.7 Water Resources
During final design, measures will be taken to minimize impacts on water quality. Best management
practices (BMPs) will be used during all phases of construction to avoid adverse impacts to water
quality. The primary concern during construction is the movement of sediment from land to
waterways. BMPs to prevent this include building berms, dikes, dams, silt fences, and silt basins.
According to preliminary design plans, all streams and stormwater flows will continue to flow or
will be directed to flow in the existing manner. Stormwater will enter the existing streams in the
project area with the possibility of slightly increased velocities at the storm drainage outlets. Project
design will include erosion control measures wherever necessary, and stream velocities will return
to normal within a short distance of the outlets.
The project is not expected to adversely affect the existing drainage patterns or water courses.
Increased urban development along the roadway corridor will result in an increase of urban
stormwater runoff. This increase has been considered in estimating design runoff for preliminary
sizing on this project.
Preliminary design plans for the SR 3015 (Airport Boulevard) widening include expansion of three
existing drainage structures. Table 12 is a summary of stream water quality classifications and
proposed impacts.

4,10.8 Flood Hazard Evaluation
' Floodplain areas are addressed by both federal and state regulations. The objectives of Executive
Order 11988, Floodplain Management, and NCDOT Order 5650.2, Floodplain Management and
' Protection, are to avoid adverse impacts due to occupancy and alteration of the 100-year floodplain
unless that location is the only practicable alternative. When floodplain areas are impacted, every
' effort must be made to minimize the potential risks to human safety and to property and to minimize
negative effects on natural and beneficial floodplains.

Wake County is a participant in the National Flood Insurance Program. The proposed widening of
' SR 3015 (Airport Boulevard) will impact approximately 0.93 ha (2.30 ac) of floodplain. This area
is based on Federal Emergency Management Agency (FEMA) maps. The impacted floodplain areas
' are Zone AF, which means that base flood elevations have been determined.
' The proposed action will be designed such that the floodway will carry the 100-year flood without
increasing the flood water elevation more than one foot at any given point. The dimensions of the
' drainage structures and the roadway grades will be adjusted and designed to avoid increasing the
flood hazard in the project area. The project will be coordinated with appropriate state and local
' officials and FEMA to ensure compliance with FEMA, state, and local floodway regulations.

4.10.9 Topography, Geography, and Soils
Soil formation and characterization result from a combination of biological and geological activity
along with the topography of an area. Based on the 1970 Soil Survey of Wake County, the soils
within the SR 3015 (Airport Boulevard) project area are generally characterized by the Creedmoor-
White Store Association. Soils within this association are generally found in gently sloping to hilly
areas. They are derived from sandstone, shale, and mudstone, are moderately well-drained, and have
a firm, clayey subsoil.
Based on the Wake County soil survey, nine soil series occur in the project area. Eight of the soil
series are identified as part of the Creedmoor-White Store Association. Congaree silt loam, which
is not identified in the Association, is shown on the soil survey as a small inclusion on the banks
above Stirrup Iron Creek. Table 13 is a summary of the soils in the project area and their
characteristics.
Two classifications of soil - hydric and prime farmland - receive special consideration. A hydric
soil is one that is saturated, flooded, or ponded long enough during the growing season to develop
anaerobic conditions in the upper part (USDA, 1991). These soils typically support the growth of
hydrophytic vegetation and are one of the three parameters used to identify jurisdictional wetlands.
According to the Wake County Soil and Water Conservation District, Chewacla, a poorly drained
floodplain soil, is the only series in the project area that is on the hydric soils list. Though none of
the land adjacent to SR 3015 (Airport Boulevard) is currently cultivated and most of it is developed,
Chewacla, Mayodan sandy loam, Congaree silt loam, and Creedmoor sandy loam are listed as prime
farmland soils. Because this land is within the corporate limits of the Town of Morrisville and
dedicated for industrial/commercial use, it is exempt from the Farmland Protection Policy Act.

4.11 Secondary Impacts
' Secondary impacts occur as a result of development induced by a project. The SR 3015 (Airport
Boulevard) corridor is already highly developed, with many of the vacant tracts planned for
industrial or commercial uses. The Town of Morrisville Land Use Study identifies SR 3015 (Airport
Boulevard) as a road serving these developments. As permitted by existing zoning, growth is
' occurring along SR 3015 (Airport Boulevard) as well as the intersecting streets and will continue
with or without the widening. Control of land use plans and review of zoning requests will remain
' the responsibility of local officials. Existing and future businesses will experience improved access
to transport goods, services, and employees as a result of the proposed project. Because most of the
land within the proposed right-of-way and construction limits already is disturbed, no adverse
' secondary or cumulative impacts are expected on the social or natural environments.

4.12 Visual Impacts
SR 3015 (Airport Boulevard) is predominantly developed with commercial and industrial buildings,
vacant lots zoned and planned for additional commercial development, and several scattered
residences. No adverse visual impacts will result from widening the existing roadway. While
opportunities for additional landscaping will be limited by space constraints, they will be considered
during detailed design.
4.13 Hazardous Material Sites
A file search was conducted on the project area to identify any potential hazardous material sites
including generators, treaters, and disposers of hazardous wastes; landfills; sewage treatment
facilities; garbage dumps; abandoned service stations with underground storage tanks (USTs); fuel,
oil and gasoline storage tanks; and lagoons. The following sources were reviewed at the N.C.
Department of Environment, Health, and Natural Resources:
• Hazardous Waste Branch Files
• Special Incidents Branch Files
• Superfund Section Branch Files
• Solid Waste Branch Files
NCDOT conducted a GeoEnvironmental Impact Study along SR 3015 (Airport Boulevard). Based
on this field reconnaissance, four sites in the project area have current or former fuel pump
operations with USTs:
• Abandoned gasoline station in northeast quadrant of NC 54/SR 3015 (Airport Boulevard)
intersection; records show removal of three USTs with some contaminated soil remaining on
the site.
• Citgo station in northwest quadrant of NC 54/SR 3015 (Airport Boulevard) intersection, with
three USTs and remediation ongoing for a reported incident.
' Amoco station on east side of SR 3015 (Airport Boulevard) across from Slater Road, with four
USTs.

required at the abandoned site. The incident remediation status at this location will be reviewed
prior to right-of-way acquisition.
The GeoEnvironmental Impact Study also indicates that no regulated or unregulated dump sites or
landfills occur in the project area.
4.14 Construction Impacts
' Short-term construction impacts may occur in the areas of water quality, air quality, natural
resources, and noise. The potential impacts can be minimized by careful adherence to established
' construction methods. These methods are described below:
' Waste and debris will be disposed of in areas outside of the right-of-way and provided by the
contractor, unless otherwise required by the plans or special provisions or unless disposal within
the right-of-way is permitted by the engineer. Disposal of waste or debris in active public waste
' or disposal areas will not be permitted without prior approval by the engineer. Such approval
will not be permitted when, in the opinion of the engineer, it will result in excessive siltation or
pollution.

P

H
n
During construction of the proposed project, all material resulting from clearing, grubbing,
demolition, or other operations will be removed from the project, and disposed of by the
contractor. Any merchantable timber should be salvaged. If vegetation is disposed of by
burning, all burning will be done in accordance with applicable local laws and regulations of the
North Carolina SIP for air quality in compliance with 15 NCAC 2D.0520. Additionally, trees
outside of the construction limits should be protected from construction activities to prevent
skinning tree trunks by use of heavy equipment, exposing roots, smothering trees from fill dirt
around the base, or accidentally spilling petroleum.
• Borrow pits and ditches will be drained as practicable to alleviate breeding areas for mosquitoes.
• Care will be taken not to block existing drainage ditches.
• There will be strict adherence to the erosion control plan by the contractor, including limiting
areas and duration of exposed earth and stabilizing exposed areas as quickly as possible.
Careful attention to erosion control will be concentrated at the Stirrup Iron Creek and other
creek crossings.
43
n

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

1 Dear Mr. Vick:
.
Thank you for your letter of October 1, 1995 requesting information from the U* S
1 Fish and Wildlife Service (Service) on evaluating the potential environmental
impacts of the above-referenced project. This report provides sccping
information and is provided in accordance with provisions of the Fish and
Wildlife Coordination Act, as amended (16 U.S.C. 661-667d) and Section 7 of the
1 Endangered Species Act of 1973 (16 U.S.C. 1531-1543).
Preliminary planning by the North Carolina Department of Transportation (NCDOT)
calls for widening Airport Boulvevard (SR 3015) from the I-40 exit ramps to NC
1 54. The length of the project is approximately 1.89 miles.
The Service's review of any environmental document would be greatly facilitated
if it contained the following information:
1 1. A description of the fishery and wildlife resources within existing and
required additional right-of-way and any areas, such as borrow areas,
which may be affected directly or indirectly by the proposed project.
1 2. A list and acreage of habitat, by cover type, that will be impacted.
Wetland types should follow the wetland classification scheme of the
National Wetlands Inventory. This list should also give the acreage of
each wetland type to be affected by the project as determined by the
1 Federal Manual for Identifying and Delineating Jurisdictional Wetlands.
3. Techniques which will be employed for designing and constructing any
wetland crossings, relocating stream channels or for creating
1 replacement wetlands.
4. The environmental impacts, both secondary and cumulative, that are
likely to occur after construction as a direct result of the proposed
1 project and an assessment of the extent to which the proposed project
will have secondary impacts and add to cumulative impacts.
5. Mitigation measures which will be employed to avoid, minimize, rectify,
1 reduce, or compensate for habitat value losses associated with the
project. These measures should include plans for replacing unavoidable
wetland losses.
The attached page identifies the Federally-listed endangered, threatened, and
1 candidate species which occur in Wake County. The section of the environmental
document regarding protected species should contain the following information:
1

1. A specific description of the proposed action to be considered;
2. A description and accompanying map of the specific area used in the
analysis of direct, indirect, and cumulative impacts;
3. A description of the biology and status of the listed species and of the
associated habitat that may be affected by the action, including the
results of an onsite inspection.
4. An analysis of the "effects of the action" on the listed species and
associated habitat:
a. Direct and indirect impacts of the project on listed species.
' Indirect effects are those that are caused by the proposed action
and are later in time but are still reasonably certain to occur;
b. A discussion of the ?sr-ironmen*_ai baseline which includes
' interrelated, interdependent, past and present impacts of Federal,
State, and private activities in the project and cumulative
effects area;

C. Interrelated actions are those that are part of a larger action
and depend on the larger action for their justification;
d. Cumulative impacts of future State and private activities (not
requiring Federal agency involvement, that will be considered as
part of future Section 7 consultation);
5. Summary of evaluation criteria used as a measurement of potential
effects;
6. A description of the manner in which the action may affect any listed
species or associated habitat including project proposals to
reduce/eliminate adverse effects;
7. Based on evaluation criteria, a determination of whether the project is
not likely to adversely affect or may affect threatened and endangered
species.
Candidate species refer to any species being considered by the Service for
listing as endangered or threatened but not yet the subject of a proposed rule.
These species are not legally protected under the Act or subject to its
provisions, including Section 7, until formally proposed or listed as threatened
or endangered. New data could result in the formal listing of a candidate
species. This change would place the species under the full protection of the
Endangered Species Act, and necessitate a new survey if its status in the project
corridor is unknown. Therefore, it would be prudent for the project to avoid any
adverse impact to candidate species or their habitat. The North Carolina Natural
Heritage Program should be contacted for information on species under State
protection.
The Service appreciates the opportunity to comment on this project. Please
continue to advise us of the progress of this project, including your official
determination of the impacts of this project.
Sincerely yours,
Susan M. Zwick6r

DiViSIGN OF
HIGHWAYS a
Reference is made to your letter of October 3, 1995, soliciting comments
for the proposed widening of Airport Boulevard near Morrisville, Wake County,
North Carolina (NCDOT TIP No. U-3344).
Our review of the project indicates that the proposed work may involve the
discharge of excavated or fill material into waters and/or wetlands. Effected
water bodies include Stirrup Iron Creek, below its headwaters, and unnamed
tributaries to Crabtree Creek and Stirrup Iron Creek, above their headwaters.
Prior Department of the Army permit authorization, pursuant to Section
404 of the Clean Water Act of 1977, as amended, will be required for the
discharge of excavated or fill material into waters and/or wetlands in
conjunction with this project, including the disposal of construction debris.
Under our mitigation policy, impacts to wetlands should first be avoided or
minimized. We will then consider compensation or mitigation for unavoidable
impacts. When final plans are completed, including the extent and location of
any work within waters of the United States and wetlands, our Regulatory
Branch would appreciate the opportunity to review these plans for a project-
specific determination of Department of the Army permit requirements. It is
possible, if the impacts from the proposed project are minor, that the work
could be authorized under one or more nationwide or regional general permits.
Questions or comments pertaining to permits may be directed to Mr. Eric
Alsmeyer, of the Raleigh Field office regulatory staff, at telephone (919)
876-8441, extension 23.

possible? Why not (if applicable)?
J. To what extent can traffic congestion management techniques
alleviate the traffic problemF in the study area?
' K. Please provide a conceptual mitigation plan to help the
environmental review. The mitigation plan may state the
following:
1. Compensatory mitigation will be considered only after
wetland impacts have been avoided and minimized to the
maximum extent possible.
' 2. On-site, in-kind mitigation is the preferred method of
mitigation. In-kind mitigation within the same
watershed is preferred over out-of-kind mitigation.
3. Mitigation should be in the following order:
' restoration, creation, enhancement, and lastly banking.
Please note that a 401 Water Quality Certification cannot be
issued until the conditions of NCAC 15A: 01C.0402 (Limitations on

that the applicant state that the 401 will not be issued until
' the applicant informs DEM that the FONSI or ROD has been signed
by the Department.
' Written concurrence of 401 Water Quality Certification may
be required for this project. Applications requesting coverage

We have received information concerning the above project from the State
Clearinghouse.
We have conducted a search of our files and are aware of no structures of
historical or architectural importance located within the planning area. Therefore,
we recommend that no historic architectural survey be conducted for this project.
There are no known archaeological sites within the proposed project area. Based
on our present knowledge of the area, it is unlikely that any archaeological
resources which may be eligible for inclusion in the National Register of Historic
Places will be affected by the project construction. We, therefore, recommend that
no archaeological investigation be conducted in connection with this project.
These comments are made in accord with G.S. 121-12(a) and Executive Order XVI.

Triangle Transit Authority
MEMORANDUM
Date: October 31, 1995
To: Ms. Stacy Baldwin
Project Planning Engineer
NCDOT Planning and Environmental Branch
FASLA
From: Juanita Shearer-Swink,
Senior Transportation Planner
Subject: Airport Boulevard Widening, NCDOT TIP No. U-3344, Environmental Assessment
As I indicated in our telephone conversation on Tuesday, November 1, 1995, the proposed Regional Transit Plan for the
Triangle Region, includes a rail connection to the airport that would interface with the airport's future people mover
system. This new rail route would branch off of the North Carolina Railroad (NCRR) as it parallels NC 54 in the
vicinity of Airport Boulevard and run within or parallel to the roadway corridor as it crosses I-40 and moves onto airport
property. The new rail corridor is anticipated to reconnect to the NCRR south of its intersection with T. W. Alexander
Drive and south of General Electric Drive, potentially utilizing a rail spur which is located south of the GE Plant. In
addition to the airport, the rail line is anticipated to serve a Mid-Region Hub station which could be located in the
general vicinity of Globe Road, south of the Northern Wake Expressway.
The attached map provides a conceptual area of focus for the alignment of the airport loop rail corridor. The
accompanying Preliminary Recommendations for a Regional Transit Plan describes the Regional Rail System proposed
for the Triangle. In 1992, the Triangle Transit Authority (TTA) began working on the accompanying Triangle Fixed
Guideway Study, a long range transportation study to determine the desirability, feasibility and location of a fixed
guideway transit system to serve the Triangle Region. During the three years of technical study and far-reaching
community participation, the TTA worked to involve all of the units of local government, the business community, the
universities and private institutions. The Preliminary Recommendations for a Regional Transit Plan which resulted from
this process were adopted by the TTA Board of Trustees in February 1995.
In March 1995, the Preliminary Recommendations were transmitted to the units of local government in Durham, Orange
and Wake Counties. They were also sent to universities, employers, business and community interest groups, agencies
and organizations. Additional public input was also gathered through public hearings which took place in April 1995, in
Cary, Chapel Hill, Durham and Raleigh. TTA received resolutions of support from Durham, Orange and Wake
Counties, Cary, Chapel Hill, Durham and Raleigh, and a majority of the other Triangle Area municipalities. It also
received letters of support and input from the universities, chambers of commerce, employers, other agencies and groups
and the general public. As a result of this input, the Recommendations were revised to address or add emphasis to a
variety of issues. The Recommendations for a Regional Transit Plan, were adopted by the TTA Board of Trustees on
October 25, 1995 and will be transmitted to the Region's two MPOs for adoption, in accordance with action already
taken by their constituent units of local government.

L
The TTA currently anticipates using a diesel fueled self-propelled regional rail train unit (diesel multiple-unit or DW).
They run on conventional rail tracks and can handle a 2%2% to 3% gradient. The train units are comprised of two (or
three) body halves which are articulated to allow a turning radius of about 300 feet. The trains are about 9%2 feet wide
and can use low or high platforms. Corridor widths will depend largely on the operational circumstances, but we need to
provide for a double track operation with roadway/railway crossings grade separated to the greatest extent possible.
' Depending on the circumstances, we would need to begin by looking at a 50 to 100 foot wide corridor. However,
elevated and/or isolated locations such as a median could operate in a narrower corridor.
' We believe it is very important to discuss this project with you in greater detail so that both TTA and NCDOT have a
clear understanding of both projects. The Airport Boulevard Corridor is likely to be critical to the operation of rail
access to the airport. We therefore look forward to being included in this planning process, and working on this project
' with you.

K. Please provide a conceptual mitigation plan to help the
environmental review. The mitigation plan may state the
following:
1. Compensatory mitigation will be considered only after
- - - wetland impacts have been avoided and minimized to the
maximum extent possible.
2. -On-site, in-kind mitigation is the preferred method of
mitigation. In-kind mitigation within the same
watershed is preferred over out-of-kind mitigation.
3. Mitigation should be in the following order:
restoration, creation, enhancement, and lastly banking.
Please note that a 401 Water Quality Certification cannot be
issued until the conditions of NCAC 15A: 01C.0402 (Limitations on
Actions During NCEPA Process) are met. This regulation prevents
DEM from issuing the 401 Certification until a FONSI or Record of
Decision (ROD) has been issued by the Department requiring the
document.- If the 40I-Certification application is submitted for
-review prior to issuance of-the FONSI or ROD, it is recommended
that the applicant state that the 401 will not be issued until
the applicant informs DEM that the FONSI or ROD has been signed
_
-----by -t-he-Department.
Written concurrence of 401 Water Quality Certification may
be required for this project. Applications requesting coverage
under our General Certification 14 or General Permit 31 will
require written concurrence. Please be aware that 401
Certification may be denied if wetland or water impacts have not
been avoided and minimized to the maximum extent practicable.

MEMORANDUM TO: Mrs. Chrys Baggett, Director
State Clearinghouse
Dept. of Administration
FROM: H. Franklin Vick, P. E., Manager
Planning and Environmental Branc
SUBJECT: Airport Boulevard Widening, NCDOT TIP No. U-3344,
Environmental Assessment
The Planning and Environmental Branch of the Division of Highways is
preparing an Environmental Assessment (EA) for the subject project. The
project is included in the 1996-2002 North Carolina Transportation
Improvement Program.
The firm of Kimley-Horn and Associates, Inc., has been retained to
prepare a State Environmental Assessment for the proposed widening of Airport
Boulevard (SR 3015) from the I-40 exit ramps to NC 54. The length of the
project is approximately 1.89 miles.
:-' The purpose of this letter is to solicit input from agencies and
individuals concerning the potential impact of the proposed project upon
social, economic, demographic, land use, and environmental conditions near
the project. Alternates will be investigated and evaluated for widening the
road to five lanes with a 100 foot wide right-of-way. No control of access
is proposed for the proposed project. The attached map shows the project in
relationship to the study area.
Airport Boulevard extends from US 70 to NC 54. Retail, office,
warehousing, and light industrial development adjoin much of the
right-of-way. Portions of the roadway already have been widened where they
front commercial development, including Triangle Factory Outlet. Several
segments, however, are still two lanes. The roadway crosses Stirrup Iron
Creek and two unnamed tributaries.
Please note that there will be no formal interagency scoping meeting for
this project. This letter, therefore, constitutes solicitation for scoping
comments related to this project. To allow us to fully evaluate the impacts

concerning any beneficial or adverse impacts of the proposed project relating
to the interest of your agency.
