Location
Directions to Site: The proposed project area includes approximately 112 acres of PTIA
land, used by tenant Timco Aviation Services dba Haeco Airframe Services (HAECO),
located southeast of PTIA Runway 5R/23L, at 623 Radar Road, in Greensboro, Guilford
County, North Carolina.
Project Area (acres): 112 acres Nearest Town: Greensboro
Nearest Waterway: UT to Horsepen Creek River Basin: 03030002
Latitude and Longitude: 36.096914°N, -79.931388°W
Existing Site Conditions
The proposed project area is located within the Carolina Slate Belt of the Piedmont
Physiographic Province. This region's geology consists of weakly metamorphosed
sedimentary and volcanic rocks. The site geomorphology generally includes flat and
developed uplands bisected by a relatively narrow undeveloped drainage sloping north to
south. The developed portions are primarily aircraft hangars, concrete apron, taxiway
connectors, and support facilities including parking lots and stormwater ponds. The
undeveloped portion includes early - to mid -successional forest with small streams and
adjacent wetlands. Elevation across the site ranges from approximately 893 feet above
mean sea level (MSL) in the southwest extent of the property, to 836 feet MSL in the
downstream extent of the undeveloped drainage. Soils are mapped as Urban land (Ur),
Mecklenburg sandy clay loam (MhB2, MhC2), and Iredell fine sandy loam (IrB). The
Mecklenburg series consists of very deep, well drained, slowly permeable soils on
Piedmont uplands. The Iredell series consists of moderately well drained, very slowly
permeable soils on Piedmont uplands. None of these series are included on the 2014
National Hydric Soils List for Guilford County, North Carolina. Average annual
precipitation for Guilford County is 43.1 inches.
Historically, similar sites in the Piedmont were used primarily for farming, with forested
areas on the steeper slopes and bottomlands. Airport runways appear to the north of the
site on topographic maps as early as 1952, with the site itself a mixture of pasture and
forest according to 1967 aerial photgraphy. Current development on the site took place
between 1979 and 1993. Currently, the site includes HAECO aerospace -related industry
on both the east and west sides, with an approximately 16 -acre central portion remaining
as a primarily forested drainage. Forested uplands of the project area consist of canopy
species such as red maple (Acer rubrum), loblolly pine (Pinus taeda), black cherry
(Prunus serotina), sweetgum (Liquidambar styraciflua), understory species including
eastern red cedar (Juniperus virginiana), mimosa (Albizia julibrissin), and Chinese privet
(Ligustrum sinense), and herbaceous species such as greenbriar (Smilax rotundifolia), and
poison ivy (Toxicodendron radicans).
Version 7.8.2014 Page 2
The project area is bordered to the north by PTIA runway 5R -23L, to the east by the
Honda Aircraft Company World Headquarters, to the west by the Cessna Citation Service
Center, and to the south by Radar Road and a Harris -Teeter grocery distribution facility.
General area land use includes PTIA and associated development, commercial and
industrial development to the south of the airport, and residential land to the north of the
airport, as well as several large state maintained highways (I-40 and I-73/ future I-840)
and those under construction (I-73 and the I-73 connector).
Michael Baker Engineering, Inc. conducted a jurisdictional delineation for the site in
2012. The jurisdictional boundaries were verified by the Corps, and a Jurisdictional
Determination was approved on June 19, 2015 (Corps Action ID: SAW -2015-00920). All
streams on site are considered Relatively Permanent Waters, have perennial flow
regimes, and are unnamed tributaries to Horsepen Creek, which flow via Horsepen Creek
and Reedy Fork to the Haw River, a Traditionally Navigable Water. These streams all
carry the NC Division of Water Resources (NCDWR) best usage classification of "WS -
III NSW." WS -III refers to those waters used as water supply for drinking, culinary, or
food processing purposes where a WS -I or II classification is not feasible. WS -III waters
are generally in low to moderately developed watersheds. NSW is a supplemental
classification intended for waters needing additional nutrient management due to being
subject to excessive growth of microscopic or macroscopic vegetation. There are no
designated Outstanding Resource Waters (ORW), High Quality Waters (HQW), Water
Supply I (WS -I), or Water Supply (WS -II) waters within 1.0 mile of the project area. The
wetlands within the project area are all of the Headwater Forest wetland type, according
to the North Carolina Wetland Assessment Method (NCWAM). These on-site features
generally have plant assemblages containing trees and shrubs such as black willow (Salix
nigra), red maple, sweetgum, tag alder (Alnus serrulata), and Chinese privet, and
understory species such as jewelweed (Impatiens capensis), sensitive fern (Onoclea
sensibilis), soft rush (Juncus effusus), woolgrass (Scirpus cyperinus) and poison ivy. Soils
within these feature are primarily loamy with a low chroma (IOYR 3/1) matrix and bright
(I OYR 7/8) redoximorphic concentrations. Typical of wetlands in small stream valleys,
these wetlands display hydrology indicators such as high water tables, soil saturation,
oxidized rhizospheres on living roots, and drainage patterns.
Applicant's Stated Purpose
The purpose of the project, as stated by the applicant, is as follows:
The proposed improvements would address the need to service two wide-bodied aircraft
simultaneously by providing movement and hangar space. HAECO requires the capacity
to service wide-bodied aircraft to meet current demand and to integrate its US operations
with its international business of maintaining wide-bodied aircraft. These improvements
will also provide a needed connection between the two sides of the existing HAECO
complex to allow for movement of vehicles, supplies and equipment from one side to the
other without having to cross airport taxiways or to depart and reenter secured areas for
travel along public roads. The project would increase operational capabilities and
improve efficiency at HAECO's PTIA facility.
Version 7.8.2014 Page 3
Project Description
The applicant has proposed to permanently discharge fill material into 1,601 linear feet of
perennial stream channel and 0.81 acre of riparian, non-riverine wetlands, to expand the
existing HAECO facility. The proposed impacts are the direct result of culvert and fill
installation associated with bringing the site elevations up to match adjacent grades, to
facilitate:
• Expansion of the existing concrete apron by approximately 204,600 sq. ft., with
engine run-up pad and 21,200 sq. ft. connector throat to an existing Taxiway M
connector (the connector throat would also link the two sides of the HAECO
complex);
Construction of an approximately 177,400 sq. ft. two -bay wide-body aircraft
maintenance hangar;
Construction of an approximately 3 3,8 10 sq. ft. support annex;
Construction of a new fire/water provision and expansion of the existing
hazardous materials (HazMat) facility;
• Addition of vehicle and pedestrian access and fire lanes.
Following initial clearing and grubbing operations, the applicant would first construct
storm sewer lines to collect and bypass all stream and wetland flows, and then add
approximately 47,096 cubic yards of clean fill material to reach desired grade. All waters
of the US within the 16 -acre drainage would be considered permanent losses.
The applicant submitted an Alternatives Analysis for taxiway alignment that includes
four On-site Alternatives. This information has been included with this Public Notice as
well. Supplemental documentation including project plans and a narrative can be found
on the District Website at
http://www.saw.usace.army.mil/Missions/Re.ug latoi3PermitProgram/PublicNotices.aspx.
Avoidance and Minimization
The applicant provided the following information in support of efforts to avoid and/or
minimize impacts to the aquatic environment:
Construction of the taxiway stream crossing will minimize smothering of
organisms by utilizing pump -around methods, minimize construction time,
controlling turbidity through adherence to the Erosion and Sedimentation Control
Plan, preventing creation of standing water, and preventing drainage of wet areas;
• During construction, physiochemical conditions will be maintained and potency
and availability of pollutants will be reduced via limiting material to be
discharged, adding treatment substances if necessary including chemical
Version 7.8.2014 Page 4
flocculants to enhance the deposition of suspended particulates in appropriate
disposal areas;
The effects of dredged or fill material may be controlled by selecting discharge
methods and disposal sites where the potential for erosion, slumping or leaching
of materials into the surrounding aquatic ecosystem will be reduced. These
methods include using containment levees, sediment basins, and cover crops to
reduce erosion;
• Discharge effects will also be controlled by containing discharged material
properly to prevent point and nonpoint sources of pollution, and timing the
discharge to minimize impact;
The effects of the discharge will be minimized by orienting dredged/fill material
to minimize undesirable obstruction to the surface water or natural flow, utilizing
natural contours to minimize the size of the fill, using silt screens or other
appropriate methods to confine suspended particulates/turbidity to a small area
where settling or removal can occur, confining and minimizing the release of
suspended particulates to decrease turbidity levels and maintain light penetration
for organisms, and setting limitations on the amount of material to be discharged
per unit of time or volume of receiving water;
The applicant will employ appropriate maintenance and operation on equipment
or machinery, ensure adequate training, staffing, and working procedures, use
machinery and techniques that are especially designed to reduce damage to
streams, design access roads using culverts, open channels, and diversions that
will pass both low and high water flows, accommodate fluctuating water levels,
and maintain circulation and faunal movement, and employ appropriate
machinery and methods of transport of the material for discharge.
• The applicant will minimize adverse effects on plant and animal populations by
minimizing changes in water flow patterns, avoiding the creation of airport
wildlife hazards, timing discharges to avoid spawning or migration seasons and
other biologically critical time periods, and avoiding the destruction of remnant
natural sites within areas already affected by development.
Compensatory Mitigation
The applicant offered the following compensatory mitigation plan to offset unavoidable
functional loss to the aquatic environment:
Impacts to the stream and wetlands are proposed be compensated through payment to the
NC Division of Mitigation Services (NCDMS), for the permanent stream and wetland
impacts associated this project.
The applicant did not indicate a proposed stream/wetland credit to impact ratio or include
an acceptance letter from NCDMS with the application.

Essential Fish Habitat
Pursuant to the Magnuson -Stevens Fishery Conservation and Management Act, this
Public Notice initiates the Essential Fish Habitat (EFH) consultation requirements. The
Corps' initial determination is that the proposed project would not effect EFH or
associated fisheries managed by the South Atlantic or Mid Atlantic Fishery Management
Councils or the National Marine Fisheries Service.
Cultural Resources
Pursuant to Section 106 of the National Historic Preservation Act of 1966, Appendix C of
33 CFR Part 325, and the 2005 Revised Interim Guidance for Implementing Appendix C,
the District Engineer consulted district files and records and the latest published version
of the National Register of Historic Places and initially determines that:
❑ Should historic properties, or properties eligible for inclusion in the National
Register, be present within the Corps' permit area; the proposed activity requiring
the DA permit (the undertaking) is a type of activity that will have no potential to
cause an effect to an historic properties.
® No historic properties, nor properties eligible for inclusion in the National
Register, are present within the Corps' permit area; therefore, there will be no
historic properties affected. The Corps subsequently requests concurrence from
the SHPO (or THPO).
❑ Properties ineligible for inclusion in the National Register are present within the
Corps' permit area; there will be no historic properties affected by the proposed
work. The Corps subsequently requests concurrence from the SHPO (or THPO).
❑ Historic properties, or properties eligible for inclusion in the National Register,
are present within the Corps' permit area; however, the undertaking will have no
adverse effect on these historic properties. The Corps subsequently requests
concurrence from the SHPO (or THPO).
❑ Historic properties, or properties eligible for inclusion in the National Register,
are present within the Corps' permit area; moreover, the undertaking may have an
adverse effect on these historic properties. The Corps subsequently initiates
consultation with the SHPO (or THPO).
❑ The proposed work takes place in an area known to have the potential for the
presence of prehistoric and historic cultural resources; however, the area has not
been formally surveyed for the presence of cultural resources. No sites eligible for
inclusion in the National Register of Historic Places are known to be present in
the vicinity of the proposed work. Additional work may be necessary to identify
and assess any historic or prehistoric resources that may be present.
Version 7.8.2014 Page 6
The District Engineer's final eligibility and effect determination will be based upon
coordination with the SHPO and/or THPO, as appropriate and required, and with full
consideration given to the proposed undertaking's potential direct and indirect effects on
historic properties within the Corps-indentified permit area.
Endangered Species
Pursuant to the Endangered Species Act of 1973, the Corps reviewed the project area,
examined all information provided by the applicant and consulted the latest North
Carolina Natural Heritage Database. Based on available information:
❑ The Corps determines that the proposed project would not affect federally listed
endangered or threatened species or their formally designated critical habitat.
❑ The Corps determines that the proposed project
may affect, not likely to adversely affect federally listed endangered or threatened
species or their formally designated critical habitat. The Corps initiates
consultation under Section 7 of the ESA and will not make a permit decision until
the consultation process is complete.
® The Corps is not aware of the presence of species listed as threatened or
endangered or their critical habitat formally designated pursuant to the
Endangered Species Act of 1973 (ESA) within the project area. The Corps will
make a final determination on the effects of the proposed project upon additional
