shall be utilized to prevent exceedances of the appropriate turbidity water quality standard (50
NTUs in all fresh water streams and rivers not designated as trout waters; 25 NTUs in all lakes
and reservoirs, and all saltwater classes; and 10 NTUs in trout waters);
2. All sediment and erosion control measures placed in wetlands or waters shall be removed and
the natural grade restored after the Division of Land Resources has released the project;
3. Measures shall betaken to prevent live or fresh concrete from coming into contact with
waters of the state until the concrete has hardened;
4. We understand that you have chosen to contribute to the Wetland Restoration Program in order
to compensate for these impacts to wetlands and/or streams. In accordance with 15A NCAC 2R
.0402, this contribution will satisfy our compensatory mitigation requirements under 15A NCAC
2H .0506(h). According to 15A NCAC 2H .0506(h), 1,179 feet of restoration will be required.
Until the Wetland Restoration Program receives and clears your check (made payable to: DENR
- Wetland Restoration Program), wetland or stream fill shall not occur. Mr. Ron Ferrell should be
contacted at 919-733-5083 ext. 358 if you have any questions concerning the Wetland

SUBJECT: Public Notice for City of Greensboro Stormwater Management Division for Proposed
Extension of Storm Sewer, Guilford Hills Subdivision, Greensboro. Action ID No.
200021059, DWQ No.000694
Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject
environmental assessment. An on-site investigation of the project area was conducted on 14 June 2000.
Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended)
and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The City of Greensboro, Storm Water Services, has altered the mitigation plan to mitigate for
impacts at a 2:1 ratio rather than the 1:1 ratio originally proposed. Mitigation is offered for impacts to
684 linear feet of an unnamed tributary to North Buffalo Creek in Guilford Hills Subdivision located in
northwest Greensboro.
We will concur with the project based on the revised mitigation plan. However, we remain
concerned about the impacts created by stream piping, as stated in our previous comments (McBride, 9
October 2000). Without more proactive measures, the City will continue to experience channel
degradation and the loss of aquatic and wildlife habitat. We encourage the City to consider protecting a
minimum 100-foot, forested riparian buffer for all perennial streams and a minimum 50-foot buffer for
intermittent streams and wetlands, and avoiding future proposals to pipe streams. As urbanization
continues in Guilford County, wildlife habitat is rapidly disappearing. These buffers would provide travel
corridors and habitat areas for wildlife displaced by secondary development, in addition to protecting
water quality, stabilizing stream banks, and providing habitat for aquatic and fisheries resources.
Thank you for the opportunity to review and comment on this project. If we can provide further
assistance, please contact Danielle R. Pender, Piedmont Region Coordinator, at [phone].

Dear Mr. Bryant:

WETLC,r?u;s ui1OuP

Reference is made to your Pre-Construction Notification (PCN) received on May 25,
2000, for the proposed 684 linear foot extension of an existing storm water sewer located off
Overbrook Drive, adjacent to an unnamed tributary of North Buffalo Creek, in Greensboro,
Guilford County, North Carolina. This PCT: requested our review and verification that your
project can be authorized by Department of the Army (DA) nationwide permits pursuant to
Section 404 of the Clean Water Act.
The referenced PCN requested DA permit authorization to discharge fill into
approximately 684 linear feet of stream channel in jurisdictional waters of the United States
associated with an unnamed tributary of North Buffalo Creek. Our review of the preliminary
plans submitted with your request revealed that impacts to jurisdictional waters of the United
States are greater than those that can be authorized by DA nationwide permit pursuant to Section
404 of the Clean Water Act. Accordingly, your project as now proposed is not eligible for
authorization by nationwide permit and will require individual DA permit approval (permit
application enclosed). Alternatively, should you be able to reduce jurisdictional impacts to be
eligible for nationwide permit authorization, you will need to submit a modified PCN for our
consideration. We strongly recommend that any PCN submitted include a detailed plan of
proposed mitigation for our consideration for any stream impacts.
Please be reminded that any placement of fill in jurisdictional waters of the United States,
including wetlands, associated with your project without prior DA permit authorization will be a
violation of Section 301 of the Clean Water Act (33 U.S.C. 1311).

SUBJECT: Public Notice for City of Greensboro Stormwater Management Division for
Proposed Extension of Storm Sewer, Guilford Hills Subdivision, Greensboro.
Action ID No. 200021059
Biologists with the North Carolina Wildlife Resources Commission have reviewed the
subject environmental assessment. An on-site investigation of the project area was conducted on
14 June 2000. Our comments are provided in accordance with provisions of the Clean Water
Act of 1977 (as amended) and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended;
16 U.S.C. 661-667d).
The City of Greensboro, Storm Water Services, has proposed a storm sewer extension in
Guilford Hills Subdivision located in northwest Greensboro. This project will impact 684 linear
feet of an unnamed tributary to North Buffalo Creek. The stated purpose of this project is to
eliminate safety hazards associated with the open channel and to provide residents with full
access to their property.
The stream has been previously channelized, and is of degraded quality. However, in
most areas the stream banks are well vegetated and shaded by trees, shrubs, and vines. Both the
upstream and downstream portions of this stream were piped during original construction of the
community in the 1950's.
We hesitate to concur with the piping of any stream due to the potential negative impacts
to downstream areas and the elimination of fish and wildlife habitat. Stream piping reduces the
infiltration of storm water and associated pollutants, as well as the dissipation of stream energy.
The affected Guilford Hills residents have observed that, as a result, downstream open channel
areas typically experience "high flow rates during storm events, continual widening of the

channel, and the nuisance of floating debris (Environmental Assessment, May, 2000)". The
channel degradation witnessed by these residents is directly related to the piping of all upstream
channels. In addition, we are concerned about the cumulative impacts associated with the loss of
urban aquatic and wildlife habitats. Although currently degraded, urban songbirds and other
wildlife as well as pollution-tolerant aquatic species will typically use these relatively low-
quality urban streams. However, culverting a stream and placing it underground obviously
removes both aquatic and terrestrial habitat. Existing uses by urban wildlife are lost and future
opportunities to improve aquatic diversity, even if water quality improves, are precluded.
High, flashy flows during storm events are characteristic of Greensboro's urban streams
due to excessive piping, curb and gutter, and impervious surfaces. The storm sewer extension
proposed in this project could exacerbate these problems. We do not believe that this project is
acceptable for the following reasons. 1) The affected homes were constructed in the 1950's, the
stream flowed through these properties when they were purchased, and there was never an
agreement by the City of Greensboro or the developer to pipe this reach of stream. 2) The
stream is at least 50-70 feet away from the homes and does not appear to pose a threat to any
permanent structures. 3) Although the stream is currently degraded, the presence of riparian
vegetation and canopy cover offers benefits to fish and wildlife habitat and water quality.
We recommend denial of this project as proposed and suggest that the City of Greensboro
further pursue Alternative 4.1 Purchase of Easement described in the Environmental Assessment.
This alternative was disregarded on the basis that it would not reduce the citizens' concerns
about safety hazards associated with open channel flow through their property. As noted in the
on-site investigation, at least one of the properties currently has a fence separating the backyard
from the stream. We suggest that as part of the City's agreement to purchase the easement
surrounding this stream that they consider building a similar fence between the affected
backyards and the stream. This should reduce or eliminate the citizens' concerns with safety
issues.
Although we do not concur with the project, if the Corps of Engineers does grant a 404
permit, we would prefer to see mitigation measures directed towards replacing lost water quality
functions and aquatic habitat in the immediate impacted watershed. We do not believe that the
proposed payments to a mitigation bank at a ratio of 1:1 is adequate to compensate for the direct
and cumulative impacts to fish and wildlife resources and water quality.
Thank you for the opportunity to review and comment on this public notice. If we can
provide further assistance, please contact Danielle R. Pender, Piedmont Region Coordinator, at

Action ID No. 200021059
Dear Colonel DeLony:
This is in response to the above referenced public notice, dated September 12, 2000,
concerning the proposed culverting of an unnamed tributary to North Buffalo Creek, off of
Overbrook Drive, in Greensboro, Guilford County, North Carolina. According to the public
notice, the purpose of the project is to extend the existing storm sewers in the area. Mitigation is
proposed, in the form of payment to the North Carolina Wetlands Restoration Program at a 1:1
ratio.
The U.S. Environmental Protection Agency, Region 4, Wetlands Section (EPA), has
reviewed this proposal and recommends that the applicant be required to mitigate for impacts at a
at a 2:1 ratio. Although degraded, the project area and similar streams are important in urban or
rapidly developing areas, and may provide opportunities for potential restoration and
enhancement of functions such as water quality improvement, flood abatement, sediment
retention, and wildlife habitat and food chain maintenance. EPA does not believe that the answer
to storm water drainage issues is the culverting of creeks. We understand that the City of
Greensboro is proposing this work in the interest of protecting its inhabitants from flooding and
safety hazards. We also understand the difficulty in addressing such issues in the urban context.
However, EPA is dismayed by the proposed techniques and methods that the City of Greensboro
has chosen to pursue. However, at this time, we will not object to authorization of the project, if
appropriate compensatory mitigation is provided.
At past meetings in Charlotte and Raleigh, North Carolina concerning the future
Environmental Assessment (EA) for similar activities, EPA and the other resource agencies have
discussed their intentions that stream stabilization projects become more effective and
environmentally and geomorphologically appropriate. This project is in stark contrast with the
resource agencies' wishes, by proposing to completely remove a stream and its valuable
functions. Piping the channel will eliminate the beneficial functions of the stream which
previously existed, such as reduction of water velocity and improvement of water quality.

2
Although the water quality and habitat functions of the stream may presently be minimal, they
are certainly greater than the functions provided by a reinforced concrete pipe. Further, the
piping of the channel will likely increase the velocity of water, transporting water downstream
faster.
We note that North Buffalo Creek is listed by the North Carolina Department of
Environment and Natural Resources on the 1998 Clean Water Act Section 303(d) list as not
supporting its designated use due to point and non-point sources, including surface runoff. EPA
believes that the piping of channels upstream may contribute to the continued degradation of
water quality, and prevent North Buffalo Creek from eventually supporting its designated uses.
Conversely, the removal of culverts from streams and restoration of upstream reaches,
floodplains, and wetlands may assist in the improvement of water quality in the listed reaches of
North Buffalo Creek.
EPA recognizes that the City of Greensboro already has greenways around several
streams within the City limits. In the future, as an alternative to piping of channels, EPA
recommends that the City of Greensboro consider the opportunity to expand this system of
greenways and improve the functions of streams using more appropriate stream
restoration/stabilization techniques, such as those proposed by Dave Rosgen (1992). Given
adequate land availability adjacent to the stream, the restoration and maintenance of a
meandering stream with an associated greenway would provide storm water benefits to the City
and the receiving waters, along with aesthetic and societal benefits to the community. The
central tendency of a stream is to meander, and a stream with sinuosity is more efficient to move
sediment. Even if there is not sufficient buffer area to provide for a meandering stream, EPA
believes that there are many more natural alternatives which will provide a larger capacity for
water storage and transport, and streambank stabilization.
EPA also encourages the City of Greensboro to incorporate such proposals for effective
and geomorpho logical ly-appropri ate stream restoration, stabilization, and protection into their
storm water plan and other land-use planning and management activities, to provide water
quality, flood attenuation, habitat, and societal benefits to the City. The City should strive to
avoid future scenarios where buildings are located adjacent to a channel or within the floodplain,
and there is no available land for appropriate corrective measures. EPA also strongly
recommends that the City attempt to avoid future proposals for installation of culvert pipes in
existing streams.
Thank you for the opportunity to comment on this project. If you have any questions or
comments, please contact Kathy Matthews, of my staff, at [phone].
Sincerely,
W1 liam L. Cox, Chief

PUBLIC NOTICE
MR. ADEGBENGA N. IDOWU, CITY OF GREENSBORO, STORMWATER
MANAGEMENT DIVISION, POST OFFICE 3136, GREENSBORO, NORTH CAROLINA
27402-3136 HAS REQUESTED A DEPARTMENT OF THE ARMY (DA) PERMIT TO
AUTHORIZE THE DISCHARGE OF FILL INTO THE JURISDICTIONAL WATERS OF AN
UNNAMED TRIBUTARY OF NORTH BUFFALO CREEK ASSOCIATED WITH THE
PROPOSED EXTENSION OF EXISTING STORM SEWERS LOCATED OFF OF
OVERBROOK DRIVE, IN GREENSBORO, GUILFORD COUNTY, NORTH CAROLINA.
The following description of the work is taken from data provided by the applicant and
from observations made during a site visit by a representative of the Corps of Engineers. Plans
submitted with the application depict the excavation, culverting, and fill of approximately 684
linear feet of jurisdictional stream channel (approximately 0.3 acre) associated with an unnamed
tributary of North Buffalo Creek. This tributary is located south of Overbrook Drive and north
of Fernwood Drive in Guilford Hills Subdivision. The proposed work will begin at the outlet of
an existing storm sewer that has a crossover east of Overbrook Drive and exits at the back of the
residence located at 2513 Overbrook Drive. The tributary will be culverted and filled from this
point west behind the residences on Overbrook Drive to the point that it presently enters a storm
sewer behind the residence located at 2529 Overbrook Drive. The tributary is characterized as
being deeply incised, between high ground banks, with a top width of approximately 18 feet
apart. The streambed is heavily silted and most of the tributary's banks are part of maintained
grass lawns. The surrounding development and the fact that it is isolated between two existing
storm sewers has heavily. impacted this headwaters tributary.
Total impacts for the proposed project include the excavation, culverting, and fill of
approximately 684 linear feet (approximately 0.3 acre) of the jurisdictional waters of an unnamed
tributary of North Buffalo Creek. No jurisdictional wetlands are to be impacted by this proposed
project. The purpose of the storm sewer extension is to eliminate safety hazards associated with
the tributary's open water, steep banks and erosion. Also, the storm sewer extension will give
residents on Overbrook Drive full access and use of their backyard property. The City of
Greensboro proposes to mitigate for the 684 linear feet of jurisdictional stream impacts by
buying into the North Carolina Wetland Restoration Program at a 1:1 ratio. Plans showing the
work are included with this public notice. A copy of this public notice can be viewed on our web
page at htip://www.saw.usace.armv.mil.

2
The State of North Carolina will review this public notice to determine the need for the
applicant to obtain any required State authorization. No Department of the Army (DA) permit
will be issued until the coordinated State viewpoint on the proposal has been received and
reviewed by this agency, nor will a DA permit be issued until the North Carolina Division of
Water Quality (NCDWQ) has determined the applicability of a Water Quality Certificate as
required by PL 92-500.'
This application is being considered pursuant to Section 404 of the Clean Water Act (33
U.S.C. 1344). Any person may request, in writing within the comment period specified in the
notice, that a public hearing be held to consider this application. Requests for public hearing
shall state, with particularity, the reasons for holding a public hearing.
The District Engineer has consulted the latest published version of the National Register
of Historic Places for the presence or absence of registered properties, or properties listed as
being eligible for inclusion therein, and this site is not registered property or property listed as
being eligible for inclusion in the Register. Consultation of the National Register constitutes the
extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of
the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or
historical data may be lost or destroyed by work under the requested permit.
The District Engineer has determined, based on a review of data furnished by the applicant
and onsite observation, that the activity will not affect species, or their critical habitat, designated
as endangered or threatened pursuant to the Endangered Species Act of 1973.
The decision whether to issue a permit will be based on an evaluation of the probable
impacts, including cumulative impacts, of the proposed activity and its intended use on the
public interest. Evaluation of the probable impacts, which the proposed activity may have on the
public interest, requires a.careful weighing of all those factors, which become relevant in each
particular case. The benefits, which reasonably may be expected to accrue from the proposal,
must be balanced against its reasonably foreseeable detriments. The decision whether to
authorize a proposal, and if so the conditions under which it will be allowed to occur, are
therefore determined by the outcome of the general balancing process. That decision should
reflect the national concern for both protection and utilization of important resources. All
factors, which may be relevant to the proposal, must be considered including the cumulative
effects thereof. Among those are conservation, economics, aesthetics, general environmental
concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values
(in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion,
recreation, water supply and conservation, water quality, energy needs, safety, food and fiber
production, mineral needs, considerations of property ownership, and, in general, the needs and
welfare of the people. For activities involving the placement of dredged or fill materials in
waters of the United States, a permit will be denied if the discharge that would be authorized by
I
3
such permit would not comply with the Environmental Protection Agencies' 404(b)(1)
guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a
permit will be granted unless the District Engineer determines that it would be contrary to the
public interest.
The Corps of Engineers is soliciting comments from the public; Federal, State and local
agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate
the impacts of this proposed activity. Any comments received will be considered by the Corps of
Engineers to determine whether to issue, modify, condition or deny a permit for this proposal.
To make this decision, comments are used to assess impacts on endangered species, historic
properties, water quality, general environmental effects and the other public interest factors listed
above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an
Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act
(NEPA). Comments are also used to determine the need for a public hearing and to determine
the overall public interest of the proposed activity.
Generally, the decision whether to issue this Department of the Army (DA) permit will not
be made until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives
State certification required by Section 401 of the Clean Water Act. The NCDEM considers
whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the
Clean Water Act. The application and this public notice for the Department of the Army (DA)
permit serves as application to the NCDWQ for certification.
Additional information regarding the Clean Water Act certification may be reviewed at the
offices of the North Carolina Division of Water Quality (NCDWQ), Salisbury Street, Archdale
Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person
r;;yuesting copies upon payment of reproduction costs.
All persons desiring to make comments regarding the application for Clean Water Act
certification should do so in writing delivered to the North Carolina Division of Water Quality
(NCDWQ), Wetland/401 Unit, 1621 Mail Service Center, Raleigh, North Carolina 27699-1621, on
or before October 5, 2000, Attention: Mr. John Dorney.
Written comments pertinent to the proposed work, as outlined above, will be received in
this office, Attention: Mr. John Thomas, until 4:15 p.m., October 12, 2000, or telephone (919)
876-8441, Extension 25.

Dear Mr. Dorney:

001187
Enclosed is the application of the City of Greensboro for Department of the Army (DA)
authorization and a State Water Quality Certification for the discharge of fill into approximately
684 linear feet (0.3 acres) of the jurisdictional waters stream channel of an unnamed tributary of
North Buffalo Creek. This discharge of fill is associated with plans for the proposed extension of
existing storm sewers located off of Overbrook Drive, in Greensboro, Guilford County, North
Carolina. Your receipt of this letter verifies your acceptance of a valid request for certification in
accordance with Section 325.2(b)(ii) of our administrative regulations.
We are considering authorizing the proposed activity pursuant to Section 404 of the Clean
Water Act, and we have determined that a water quality certification is required under the
provisions of Section 401 of the same law. A Department of the Army permit will not be granted
until the certification has been obtained or waived.
In accordance with our administrative regulations, in most cases, 60 days after receipt of a
request for certification is a reasonable time for State action. Therefore, if you have not acted on
the request, or asked for an extension of time, by November 10, 2000, the District Engineer will
deem that waiver has occurred.
2
If you have questions, please do not hesitate to contact Mr. John Thomas, Raleigh
Regulatory Field Office, telephone [phone].
Sincerely,
?. /4?- ?? n

DEPARTMENT OF THE ARMY
Wilmington District, Corps of Engineers
Post Office Box 1890
Wilmington, North Carolina 28402-1890
Action ID No. 200021059 September 12, 2000
PUBLIC NOTICE
MR. ADEGBENGA N. IDOWU, CITY OF GREENSBORO, STORMWATER
MANAGEMENT DIVISION, POST OFFICE 3136, GREENSBORO, NORTH CAROLINA
27402-3136 HAS REQUESTED A DEPARTMENT OF THE ARMY (DA) PERMIT TO
AUTHORIZE THE DISCHARGE OF FILL INTO THE JURISDICTIONAL WATERS OF AN
UNNAMED TRIBUTARY OF NORTH BUFFALO CREEK ASSOCIATED WITH THE
PROPOSED EXTENSION OF EXISTING STORM SEWERS LOCATED OFF OF
OVERBROOK DRIVE, IN GREENSBORO, GUILFORD COUNTY, NORTH CAROLINA.
The following description of the work is taken from data provided by the applicant and
from observations made during a site visit by a representative of the Corps of Engineers. Plans
submitted with the application depict the excavation, culverting, and fill of approximately 684
linear feet of jurisdictional stream channel (approximately 0.3 acre) associated with an unnamed
tributary of North Buffalo Creek. This tributary is located south of Overbrook Drive and north
of Fernwood Drive in Guilford Hills Subdivision. The proposed work will begin at the outlet of
an existing storm sewer that has a crossover east of Overbrook Drive and exits at the back of the
residence located at 2513 Overbrook Drive. The tributary will be culverted and filled from this
point west behind the residences on Overbrook Drive to the point that it presently enters a storm
sewer behind the residence located at 2529 Overbrook Drive. The tributary is characterized as
being deeply incised, between high ground banks, with a top width of approximately 18 feet
apart. The streambed is heavily silted and most of the tributary's banks are part of maintained
grass lawns. The surrounding development and the fact that it is isolated between two existing
storm sewers has heavily impacted this headwaters tributary.
Total impacts for the proposed project include the excavation, culverting, and fill of
approximately 684 linear feet (approximately 0.3 acre) of the jurisdictional waters of an unnamed
tributary of North Buffalo Creek. No jurisdictional wetlands are to be impacted by this proposed
project. The purpose of the storm sewer extension is to eliminate safety hazards associated with
the tributary's open water, steep banks and erosion. Also, the storm sewer extension will give
residents on Overbrook Drive full access and use of their backyard property. The City of
Greensboro proposes to mitigate for the 684 linear feet of jurisdictional stream impacts by
buying into the North Carolina Wetland Restoration Program at a 1:1 ratio. Plans showing the
work are included with this public notice. A copy of this public notice can be viewed on our web
page at htlp://www.saw.usace.anny.mil.
2
The State of North Carolina will review this public notice to determine the need for the
applicant to obtain any required State authorization. No Department of the Army (DA) permit
will be issued until the coordinated State viewpoint on the proposal has been received and
reviewed by this agency, nor will a DA permit be issued until the North Carolina Division of
Water Quality (NCDWQ) has determined the applicability of a Water Quality Certificate as
required by PL 92-500.'
This application is being considered pursuant to Section 404 of the Clean Water Act (33
U.S.C. 1344). Any person may request, in writing within the comment period specified in the
notice, that a public hearing be held to consider this application. Requests for public hearing
shall state, with particularity, the reasons for holding a public hearing.
The District Engineer has consulted the latest published version of the National Register
of Historic Places for the presence or absence of registered properties, or properties listed as
being eligible for inclusion therein, and this site is not registered property or property listed as
being eligible for inclusion in the Register. Consultation of the National Register constitutes the
extent of cultural resource investigations by the District Engineer, and he is otherwise unaware of
the presence of such resources. Presently, unknown archeological, scientific, prehistorical, or
historical data may be lost or destroyed by work under the requested permit.
The District Engineer has determined, based on a review of data furnished by the applicant
and onsite observation, that the activity will not affect species, or their critical habitat, designated
as endangered or threatened pursuant to the Endangered Species Act of 1973.
The decision whether to issue a permit will be based on an evaluation of the probable
impacts, including cumulative impacts, of the proposed activity and its intended use on the
public interest. Evaluation of the probable impacts, which the proposed activity may have on the
public interest, requires a.careful weighing of all those factors, which become relevant in each
particular case. The benefits, which reasonably may be expected to accrue from the proposal,
must be balanced against its reasonably foreseeable detriments. The decision whether to
authorize a proposal, and if so the conditions under which it will be allowed to occur, are
therefore determined by the outcome of the general balancing process. That decision should
reflect the national concern for both protection and utilization of important resources. All
factors, which may be relevant to the proposal, must be considered including the cumulative
effects thereof. Among those are conservation, economics, aesthetics, general environmental
concerns, wetlands, cultural values, fish and wildlife values, flood hazards and flood plain values
(in accordance with Executive Order 11988), land use, navigation, shore erosion and accretion,
recreation, water supply and conservation, water quality, energy needs, safety, food and fiber
production, mineral needs, considerations of property ownership, and, in general, the needs and
welfare of the people. For activities involving the placement of dredged or fill materials in
waters of the United States, a permit will be denied if the discharge that would be authorized by
I
3
such permit would not comply with the Environmental Protection Agencies' 404(b)(1)
guidelines. Subject to the preceding sentence and any other applicable guidelines or criteria, a
permit will be granted unless the District Engineer determines that it would be contrary to the
public interest.
The Corps of Engineers is soliciting comments from the public; Federal, State and local
agencies and officials; Indian Tribes and other interested parties in order to consider and evaluate
the impacts of this proposed activity. Any comments received will be considered by the Corps of
Engineers to determine whether to issue, modify, condition or deny a permit for this proposal.
To make this decision, comments are used to assess impacts on endangered species, historic
properties, water quality, general environmental effects and the other public interest factors listed
above. Comments are used in the preparation of an Environmental Assessment (EA) and/or an
Environmental Impact Statement (EIS) pursuant to the National Environmental Policy Act
(NEPA). Comments are also used to determine the need for a public hearing and to determine
the overall public interest of the proposed activity.
Generally, the decision whether to issue this Department of the Army (DA) permit will not
be made until the North Carolina Division of Water Quality (NCDWQ) issues, denies, or waives
State certification required by Section 401 of the Clean Water Act. The NCDEM considers
whether or not the proposed activity will comply with Sections 301, 302, 306, and 307 of the
Clean Water Act. The application and this public notice for the Department of the Army (DA)
permit serves as application to the NCDWQ for certification.
Additional information regarding the Clean Water Act certification may be reviewed at the
offices of the North Carolina Division of Water Quality (NCDWQ), Salisbury Street, Archdale
Building, Raleigh, North Carolina. Copies of such materials will be furnished to any person
requesting copies upon payment of reproduction costs.
All persons desiring to make comments regarding the application for Clean Water Act
certification should do so in writing delivered to the North Carolina Division of Water Quality
(NCDWQ), Wetland/401 Unit, 1621 Mail Service Center, Raleigh, North Carolina 27699-1621, on
or before October 5, 2000, Attention: Mr. John Dorney.
Written comments pertinent to the proposed work, as outlined above, will be received in
this office, Attention: Mr. John Thomas, until 4:15 p.m., October 12, 2000, or telephone (919)
876-8441, Extension 25.

1.0 Project Description and Location
The City of Greensboro is proposing a storm sewer extension that will impact 684 feet of
an unnamed tributary to North Buffalo Creek. Upstream and downstream of this 684 feet
segment of the stream was enclosed during development in 1972. The proposed project
is located in the Guilford Hills subdivision, a single family residential community located
on the northwest side of Greensboro, North Carolina.
2.0 Purpose of Project
The purpose of the proposed storm sewer extension is to eliminate safety hazards
associated with the stream and to give the residents full access and use of their property.
Due to the stream's close proximity to homes, there are concerns with the relatively steep
banks, high flow rates during storm events, continual widening of the channel, and the
nuisance of floating debris. Because the stream runs through the middle of the residents'
back yards, piping the stream will allow the residents to gain full use and access to their
property and eliminate the safety hazards associated with the stream.
3.0 Environmental Consequences
3.1 Existing Environment
A perennial stream, which shows on the USGS quad sheet flows through this
subdivision. A portion of this stream was piped in 1979 during the construction
of the subdivision and another portion was upgraded in 1985 due to increase in
upstream development.
The length of open stream channel that crosses the properties along Overbrook
Drive is approximately 684 feet with a drainage area of approximately 65 acres.
All upstream conveyance systems in this basin are enclosed and the downstream
conveyance system is also enclosed until it crosses Benjamin Parkway & Bryan
boulevard where it discharges into a tributary of North Buffalo Creek. From there
the stream flows approximately 2.46 miles before discharging to North Buffalo
Creek.
The open stream section, along Overbrook Drive is eroding and degrading with
sizes ranging from approximately 3 feet to 5 feet in height. The vegetation on the
stream banks and floodplain varies from grass, shrubs to canopy cover provided
by some trees along the stream bank. The houses along Overbrook Drive are
located approximately 50-70 feet away from the open stream channel.
The pre-construction soil type at the project area as indicated by the Guilford
County Soils Survey, is Vance sandy loam (10-15% slopes). The top layer soil
type and the topography in this area may have been altered from the pre-
developed condition.
3.2 Existing Permits and Certifications
There were no permits or certifications obtained for the piping and channel
modification of the stream during subdivision construction in 1972.
3.3 Project Impacts
Changes in land use
The proposed sewer extension project will enclose the only portion of the system that
is still an open channel (684 feet of stream.) The stream will be excavated, the pipe
and junction boxes will be placed and constructed, and then backfilled. By piping
the stream, residents will gain full use of their back yards.
Wetlands
There are no jurisdictional wetlands other than the stream in the proposed project
area. US Army Corps of Engineers will be invited for verification. Cost of
mitigation will be paid into the state mitigation bank for the lost habitat.
Prime or unique agricultural lands
The project is located entirely within the Guilford Hills subdivision. There are no
agricultural lands in this area.
Public lands
The project will take place on private property within the designated drainage
maintenance and utility easement.
Scenic or recreational areas
There are no scenic or recreational areas located within or near the project area. The
proposed project will provide more usable land for the landowners.
Areas of archeological or historical value
The NC Department of Cultural Resources, will be contacted for properties of
architectural, historic, or archaeological significance that would be affected by the
proposed project.
Air quality
Air quality will not be impacted due to piping of the stream. There will be no
emissions as a result of this project.
Groundwater quality
The stream is a perennial stream therefore, groundwater maintains the base flow in
the stream during dry conditions. But upstream and downstream of this section are
piped, which reduces groundwater base flow. The piping will cause insignificant
change to groundwater seepage and groundwater quality.
Noise levels
Variation in noise levels will only be experienced during the construction phase of
the project as heavy machinery will be used to excavate, lay pipe, and backfill. The
project will not cause any change in noise levels except during the short construction
period.
Water supplies
The project is not located in a designated water-supply watershed. The subdivision
residents are serviced drinking water by the City of Greensboro. The project will not
have any impact on water supplies.
Shellfish or fish and their habitats
Although the stream maintains continual flow, the quality of the stream is considered
by the City to be degraded. There is limited aquatic habitat in the stream (see
Exhibit B for field assessment worksheet).
Wildlife and their habitats (presence of threatened or endangered species)
There is no evidence of wildlife habitat in the project area. The NC Natural Heritage
Program will be contacted for records of rare species, high quality natural
communities, state/federal of Significant Natural Heritage Areas at or within a one
mile radius of the proposed project.
Introduction of toxic substance
There will not be any toxic substances introduced to the environment as a result of
the proposed storm sewer extension.
Surface water quality
During construction, erosion protection measures will be implemented to reduce the
amount of sediment transport to receiving surface waters. Immediately after
construction, disturbed areas will be permanently stabilized with grass cover.
There will be no increase in "nutrients" as a result of this project.
Downstream flooding
The piping project will not cause a significant change in downstream flooding
amounts and/or frequency from what already exists. There are no structures
immediately downstream of the proposed project that experience flooding problems.
Stream scour protection
This project will be end of pipe to end of pipe construction. Rip rap outlet protection
is not needed.
4.0 Alternative Analysis
The alternative option considered for this project was to (1) purchase easement so
that City of Greensboro could have control of maintenance activities along
4
Overbrook Drive and (2) to maintain the stream channel in its current location and
provide stabilization along the stream banks.
4.1 Purchase of easement
One alternative the City considered was to purchase easement of the stream
corridor so that City of Greensboro could have access toward maintenance of the
stream corridor and to enable vegetation growth for stabilization. This option
would have given the City of Greensboro the opportunity to assist citizens with
managing this portion of their property, however, the residents noted that this
would not reduce their concern for hazards associated with open channel flow
through their property.
4.2 Maintain stream channel/provide stabilization
The other alternative considered is to maintain the stream in its current condition
and provide stabilization of sections of the stream where the banks where eroded.
This alternative would prevent further disturbance of the stream. With this
option, the City would offer to partner with the residents to plant trees and other
vegetation along the stream to keep the banks as stable as possible. However, the
residents expressed that this option will not address their concerns (safety hazards
and inability to fully use their properties) and that the only option that would meet
their needs would be to pipe the stream segment.
First, the residents' main concern is the presence of the open flowing water that is
present in their yards and close to their homes. They expressed concern for their
children's safety when they play in their yards. They also note that during storm
events the stream exhibits high water levels and velocity and that the size of the
channel cross section has increased significantly since they bought their homes.
The residents point out that stabilization of the banks will not relieve their main
concern that open channel flow exists on their property. Also, a safety barrier
such as a fence would be unacceptable by the residents and would not reduce their
concern for the safety of their children playing in their yard.
Secondly, the residents want the stream to be piped to give them more use of their
yards. The lots along Overbrook Drive are fairly small (quarter acre) and the
stream runs through the middle of their back yard. Although the residents are
concerned with the areas along the stream where the banks are 5-6' high and
nearly vertical and placing a safety barrier such as a fence would further reduce
the use of their yard.
Thirdly, the resident's point out that they do not want the dense vegetation
associated with bank stabilization. The residents stated that dense vegetation
provides a habitat for undesirable wildlife, such as snakes, and traps floatable
litter from upstream properties. They also said with the stream so close to the
homes, the dense vegetation makes their yard unattractive.
For the reasons stated above, the alternatives were not considered feasible for
implementation.
5.0 Mitigative Measures
The City of Greensboro will pay for mitigation at a 1:1 ratio for the 684 feet of
stream loss due to the storm sewer extension.
6.0 Conclusions
The proposed storm sewer extension that will impact 684 linear feet of an
unnamed tributary to North Buffalo Creek will not have a significant adverse
effect on the quality of the environment because of the following reasons:
1. The stream is currently a degraded stream (Class C NSW) with very low
aquatic habitat (see appendix B for stream quality assessment data).
2. The stream is not designated by the State as High Quality Waters,
Outstanding Resource Waters, or Water-Supply Waters. The stream is
Nutrient Sensitive Waters, however, the project will not increase nutrient
levels.
3. The City will mitigate for the loss of stream at a 1:1 ratio by paying to the
State mitigation bank.

1.0 Project Description and Location
The City of Greensboro is proposing a storm sewer extension that will impact 684 feet of
an unnamed tributary to North Buffalo Creek. Upstream and downstream of this 684 feet
segment of the stream was enclosed during development in 1972. The proposed project
is located in the Guilford Hills subdivision, a single family residential community located
on the northwest side of Greensboro, North Carolina.
2.0 Purpose of Project
The purpose of the proposed storm sewer extension is to eliminate safety hazards
associated with the stream and to give the residents full access and use of their property.
Due to the stream's close proximity to homes, there are concerns with the relatively steep
banks, high flow rates during storm events, continual widening of the channel, and the
nuisance of floating debris. Because the stream runs through the middle of the residents'
back yards, piping the stream will allow the residents to gain full use and access to their
property and eliminate the safety hazards associated with the stream.
3.0 Environmental Consequences
3.1 Existing Environment
A perennial stream, which shows on the USGS quad sheet flows through this
subdivision. A portion of this stream was piped in 1979 during the construction
of the subdivision and another portion was upgraded in 1985 due to increase in
upstream development.
The length of open stream channel that crosses the properties along Overbrook
Drive is approximately 684 feet with a drainage area of approximately 65 acres.
All upstream conveyance systems in this basin are enclosed and the downstream
conveyance system is also enclosed until it crosses Benjamin Parkway & Bryan
boulevard where it discharges into a tributary of North Buffalo Creek. From there
the stream flows approximately 2.46 miles before discharging to North Buffalo
Creek.
The open stream section, along Overbrook Drive is eroding and degrading with
sizes ranging from approximately 3 feet to 5 feet in height. The vegetation on the
stream banks and floodplain varies from grass, shrubs to canopy cover provided
by some trees along the stream bank. The houses along Overbrook Drive are
located approximately 50-70 feet away from the open stream channel.
The pre-construction soil type at the project area as indicated by the Guilford
County Soils Survey, is Vance sandy loam (10-15% slopes). The top layer soil
type and the topography in this area may have been altered from the pre-
developed condition.
3.2 Existing Permits and Certifications
There were no permits or certifications obtained for the piping and channel
modification of the stream during subdivision construction in 1972.
3.3 Project Impacts
Changes in land use
The proposed sewer extension project will enclose the only portion of the system that
is still an open channel (684 feet of stream.) The stream will be excavated, the pipe
and junction boxes will be placed and constructed, and then backfilled. By piping
the stream, residents will gain full use of their back yards.
Wetlands
There are no jurisdictional wetlands other than the stream in the proposed project
area. US Army Corps of Engineers will be invited for verification. Cost of
mitigation will be paid into the state mitigation bank for the lost habitat.
Prime or unique agricultural lands
The project is located entirely within the Guilford Hills subdivision. There are no
agricultural lands in this area.
Public lands
The project will take place on private property within the designated drainage
maintenance and utility easement.
Scenic or recreational areas
There are no scenic or recreational areas located within or near the project area. The
proposed project will provide more usable land for the landowners.
Areas of archeological or historical value
The NC Department of Cultural Resources, will be contacted for properties of
architectural, historic, or archaeological significance that would be affected by the
proposed project.
Air quality
Air quality will not be impacted due to piping of the stream. There will be no
emissions as a result of this project.
Groundwater quality
The stream is a perennial stream therefore, groundwater maintains the base flow in
the stream during dry conditions. But upstream and downstream of this section are
piped, which reduces groundwater base flow. The piping will cause insignificant
change to groundwater seepage and groundwater quality.
Noise levels
Variation in noise levels will only be experienced during the construction phase of
the project as heavy machinery will be used to excavate, lay pipe, and backfill. The
project will not cause any change in noise levels except during the short construction
period.
Water supplies
The project is not located in a designated water-supply watershed. The subdivision
residents are serviced drinking water by the City of Greensboro. The project will not
have any impact on water supplies.
Shellfish or fish and their habitats
Although the stream maintains continual flow, the quality of the stream is considered
by the City to be degraded. There is limited aquatic habitat in the stream (see
Exhibit B for field assessment worksheet).
Wildlife and their habitats (presence of threatened or endangered species)
There is no evidence of wildlife habitat in the project area. The NC Natural Heritage
Program will be contacted for records of rare species, high quality natural
communities, state/federal of Significant Natural Heritage Areas at or within a one
mile radius of the proposed project.
Introduction of toxic substance
There will not be any toxic substances introduced to the environment as a result of
the proposed storm sewer extension.
Surface water quality
During construction, erosion protection measures will be implemented to reduce the
amount of sediment transport to receiving surface waters. Immediately after
construction, disturbed areas will be permanently stabilized with grass cover.
There will be no increase in "nutrients" as a result of this project.
Downstream flooding
The piping project will not cause a significant change in downstream flooding
amounts and/or frequency from what already exists. There are no structures
immediately downstream of the proposed project that experience flooding problems.
Stream scour protection
This project will be end of pipe to end of pipe construction. Rip rap outlet protection
is not needed.
4.0 Alternative Analysis
The alternative option considered for this project was to (1) purchase easement so
that City of Greensboro could have control of maintenance activities along
Overbrook Drive and (2) to maintain the stream channel in its current location and
provide stabilization along the stream banks.
4.1 Purchase of easement
One alternative the City considered was to purchase easement of the stream
corridor so that City of Greensboro could have access toward maintenance of the
stream corridor and to enable vegetation growth for stabilization. This option
would have given the City of Greensboro the opportunity to assist citizens with
managing this portion of their property, however, the residents noted that this
would not reduce their concern for hazards associated with open channel flow
through their property.
4.2 Maintain stream channel/provide stabilization
The other alternative considered is to maintain the stream in its current condition
and provide stabilization of sections of the stream where the banks where eroded.
This alternative would prevent further disturbance of the stream. With this
option, the City would offer to partner with the residents to plant trees and other
vegetation along the stream to keep the banks as stable as possible. However, the
residents expressed that this option will not address their concerns (safety hazards
and inability to fully use their properties) and that the only option that would meet
their needs would be to pipe the stream segment.
First, the residents' main concern is the presence of the open flowing water that is
present in their yards and close to their homes. They expressed concern for their
children's safety when they play in their yards. They also note that during storm
events the stream exhibits high water levels and velocity and that the size of the
channel cross section has increased significantly since they bought their homes.
The residents point out that stabilization of the banks will not relieve their main
concern that open channel flow exists on their property. Also, a safety barrier
such as a fence would be unacceptable by the residents and would not reduce their
concern for the safety of their children playing in their yard.
Secondly, the residents want the stream to be piped to give them more use of their
yards. The lots along Overbrook Drive are fairly small (quarter acre) and the
stream runs through the middle of their back yard. Although the residents are
concerned with the areas along the stream where the banks are 5-6' high and
nearly vertical and placing a safety barrier such as a fence would further reduce
the use of their yard.
Thirdly, the resident's point out that they do not want the dense vegetation
associated with bank stabilization. The residents stated that dense vegetation
provides a habitat for undesirable wildlife, such as snakes, and traps floatable
litter from upstream properties. They also said with the stream so close to the
homes, the dense vegetation makes their yard unattractive.
For the reasons stated above, the alternatives were not considered feasible for
implementation.
5.0 Mitigative Measures
The City of Greensboro will pay for mitigation at a 1:1 ratio for the 684 feet of
stream loss due to the storm sewer extension.
6.0 Conclusions
The proposed storm sewer extension that will impact 684 linear feet of an
unnamed tributary to North Buffalo Creek will not have a significant adverse
effect on the quality of the environment because of the following reasons:
1. The stream is currently a degraded stream (Class C NSW) with very low
aquatic habitat (see appendix B for stream quality assessment data).
2. The stream is not designated by the State as High Quality Waters,
Outstanding Resource Waters, or Water-Supply Waters. The stream is
Nutrient Sensitive Waters, however, the project will not increase nutrient
levels.
3. The City will mitigate for the loss of stream at a 1:1 ratio by paying to the
State mitigation bank.

RECTOR SUBJECT: Rare Species, High Quality Natural Communities, and
Significant Natural Heritage Areas at The Proposed Storm
Sewer Extension Project Site, Overbrook Drive, Greensboro,
Guilford County, North Carolina
Dear Mr. Idowu:
The NC Natural Heritage Program (NCNHP) does not have a record of rare species,
high quality natural communities, state park and recreation areas, or Significant
Natural Heritage Areas (SNHAs) at or within a 1.0 mile radius of the proposed storm
sewer extension project site at Overbrook Drive, Greensboro, Guilford County, North
Carolina.
I have enclosed a rare species list for Guilford County. If habitat for any of these
species exists at the site, they may be present there. Consultant acquired knowledge
of the site habitat should determine if a survey is necessary.
Please do not hesitate to contact me at the address below or call me at (919) 715-
8703 if you have any questions or need further information.
Sincerely,
Susan Reece Giles
