APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Condition
Dear Ms. Reed:
You have our approval, in accordance with the attached conditions, to place fill in 136 linear feet of perennial and 212 linear feet of
intermittent unnamed tributaries to Stony Creek in order to construct roadway and driveway crossings for the Windfall subdivision in
Orange County, as described in your application received by the Division of Water Quality on April 6, 2001 and in additional
correspondence received June 5, 2001. After reviewing your application, we have determined that this fill is covered by General Water
Quality Certification Number 3289, which can be viewed on our web site at http://h2o.enr.state.nc.us/ncwetlands. This Certification allows
you to use Nationwide Permit Number 14 when it is issued by the U.S. Army Corps of Engineers. This approval is also valid for the Neuse
River Buffer Rules (15A NCAC 2B .0233). 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, Non-Discharge and Water Supply Watershed regulations. Also
this approval will expire when the accompanying 404 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 as well as the additional condition listed
below:
1. An additional condition is that stormwater shall be directed to diffuse flow at non-erosive velocities through any protected stream
buffers.
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 Cyndi Karoly at 919-733-9721 or Steve Mitchell in DWQ's Raleigh Regional Office at 919-571-4700.
Sincerely,
0?? lk?

The RO office (Steve mitchell) had some additional Questions that are now resolved. Beth Reed with
Kimely-Horn provided Steve a copy of this letter and a map depicting additional crossings associated with
the drive ways (an additional 40 feet). Therefore 212 feet of an intermittent stream crossings and 136 feet
of perennial crossings is proposed. After review RO has determined compliance with Neuse Buffer Rule,
does not recommend mitigation. RO Recommends issuance.

Comments:
Initial comments required need for the additional crossing. Three features are present on the site.
Only one is subject to the Neese Buffer Rule, Number 3. That crossing . permittable as it is
necessary and under threshold. Grossing 1 is at best over an ephemeral ditch. Crossing 2 was the
problem. THis stream is important biologically, but not subject to NBR, and the total egress for the
road crossing was 96 linear feet with three houses requiring access. One house is out of the buffer.
the two driveway connections will impact 20 foot each with a total impact of 136 linear feet,

Re: DWQ Project # 010506
M/I Schottenstein Homes, Inc.
Windfall Subdivision - Orange County
Dear Mr. Smith:
Per your request, the attached 81/2" x 11 site plan shows the location of the
proposed driveway crossings for Lots 13 and 14 for the above referenced
subdivision. Each driveway will be a 10-foot crossing (30" corrugated aluminum
pipe) with 5' fill slopes on each side. Each driveway crossing with impact 20-1f
of stream (40 If total). In addition to the 96-If of stream disturbance for the
proposed road crossing, the addition of the driveway crossings will bring the total
stream impact for this tributary to 136-1f.
It is our understanding that this additional information is sufficient to release
DWQ's hold of this project and facilitate the issuance of the 401 Certification.
Thank you for your assistance with this project. If you have any questions or
need any additional information, please do not hesitate to contact me at (919)
677-2073.
Very truly yours,
KIMLEY-HORN AND ASSOCIATES, INC.

Dear Sirs:
The Division of Water Quality has reviewed your plans for the discharge of fill material
into 212 linear feet of streams and 0.13 acres of buffers located at the proposed Wnfall subdivision
in Orange County for road crossings. Insufficient evidence is present in our files to conclude that
your project must be built as planned in waters and/or wetlands in accordance with 15A NCAC 2H
.0506. Therefore, unless modifications of the proposal are made as described below, we will have
to move toward denial of your 401 Certification as required by 15A NCAC 2H .0507(e) and will
place this project on hold as incomplete until we receive this additional information, we are
requesting (by copy of this letter) that the U.S. Army Corps of Engineers place your project on
administrative hold.
Please provide us with information supporting your position that states your project must
be constructed as planned and that you have no practicable alternative to placing fill in these
waters and/or wetlands. Specifically your site plan does not clearly depict each of these streams
and where it does, it shows construction within 50 feet of the channel. Please provide a revised
site plan which clearly shows that houses will be constructed outside the protected stream buffer?
Any documentation such as maps and narrative that you can supply to address alternative designs
for your project may be helpful in our review of your 401 Certification.
Please respond within three weeks of the date of this letter by sending a copy of this
information to me and one copy to Raleigh Regional Office at [phone]. If we do not hear
from you in three weeks, we will assume that you no longer want to pursue this project and we will
consider the project as withdrawn. If you have any questions, please telephone John Dorney at

V'Q
Dear
You have our appZv(
ord
ance with the attach conditions and those listed below, to impact
? a a IeZ li ar feet of streams and 0 t i 3 acresof
stream buffers for at as you described in your application dated
, 2000. After reviewing your application, we have decided that this fill is covered by General
Water Quality Certification Number . This certification allows you to use Nationwide Permit
Number _ when the Corps of Engineers issues it. This approval is also valid for the Neuse River
buffer rules (15A N CAC 2B .033). 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. 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 except as modified
below. If you change your project, you must notify us and you may be required to send us a new application.. If the
property is sold, the new owner must be given a copy of this 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) (6) and (7). This approval
shall expire when the corresponding Nationwide Permit expires or as otherwise provided in the General Certification.
For this approval to be valid, you must follow the conditions listed in the attached certification and any additional
conditions listed below.
1. Deed notifications or similar mechanisms shall be placed on all remaining jurisdictional wetlands and waters or
areas within 50 feet of all streams and ponds to notify the state in order to assure compliance for future
wetland and/or water impact. These mechanisms shall be put in place within 30 days of the date of this letter
or the issuance of the 404 Permit (whichever is later).
2. Stormwater shall be directed to flow at non-erosive velocities across the entire protected stream buffers.
3. An additional condition is that a final, written stormwater management plan shall be approved by this Office
before the impacts specified in this Certification occur. The stormwater management plan must include plans
and specifications for stormwater management facilities designed to remove 85% TSS according to the most
recent version of the NC DENR Stormwater Best Management Practices Manual. Also, before any permanent
building is occupied at the subject site, the facilities, as approved by this Office, shall be constructed and
operational, and the stormwater management plan, as approved by this Office, shall be implemented.
4. Upon completion of the project, the applicant shall complete and return the enclosed "Certification of
Completion Form" to notify DWQ that all the work included in the 401 Certification has been completed. The
responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the Division of

JD, I did the site visit at this project and found low and behold that
there are two stream crossings that have a total of 212 linear feet of
impact (one at 116 and the other at 96). As I understand the rules both
catchments are excempt from any mitigation because they are both less
than 150 If. That's what I conveyed to the consultant anyway. Both
stream are nice (one much nicer that the other) perennial systems.

FROM: Danielle R. Pender, Piedmont Region Coordinator

DATE: 21 May 2001
SUBJECT: Pre-construction Notification Application for Windfall Subdivision, Orange
County, North Carolina. DWQ ID: 010506
Biologists with the North Carolina Wildlife Resources Commission have reviewed the
subject pre-construction notification. The project area was viewed on 11 May 2001 by NCWRC
biologists to further assess impacts to fish and wildlife resources. Our comments are provided in
accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife
Coordination Act (48 Stat. 401, as amended; 16 U.S.C, 661-667d), and North Carolina General
Statutes (G. S, 113 -13 1 et scq.).
Applicant proposes to impact 308 linear feet of stream with culverts and fill for access
roads in a 25-acre residential development, Windfall Subdivision. The streams that run through
the project are tributaries to Stony Creek. Stony Creek, designated as WS-IV-NSW, is a
tributary of the Eno River and is within the Neuse River basin. An additional 0.13 acres of
impacts are proposed to occur within the Neuse buffer zone. According to the site map, there are
a number of lots that have streams running through them or are located within the Neuse River
buffer zone. Additionally, in the Eno River there are numerous records for the existence of listed
species, including the federal species of concern and state endangered, green floater (Lasn:lgona
subviridis), the federal species of concern and state threatened, Atlantic pigtoe (Fusconaia
masons) and yellow lampmussel (Larnpxilis cariosa), and the federal species of concern and state
significantly rare, pinewoods shiner (Lythrurus matutinus). Current habitat in the project area

consists of mixed hardwoods and limited residential development on adjacent properties. The
perennial stream drains from the southeast corner of the property through a culvert under Old
Durhain Road (NC 10).
Stream piping and placing fill in aquatic resources can result in significant negative
impacts to downstream areas and eliminate fish and wildlife habitat, Stream piping reduces the
infiltration of stoma water and associated pollutants, as well as the dissipation of stream energy.
Piping a stream and placing it underground obviously removes both aquatic and terrestrial
habitat. Existing uses by wildlife are lost and fttture opportunities to improve aquatic diversity,
evtm if water quality improves, are precluded. We are particularly concerned about the many
listed species that are located downstream of the proposed project. Likewise we are concerned
about impacts to wetlands due to their wildlife habitat value and the well-known beneficial
functions that they provide for flood control and water quality protection. Changes in land use
from a primarily forested area to a suburban landscape may exacerbate channel degradation due
to increased stormwater runoff. However, we wig not object to the project provided that the
following recommend conditions are incorporated into the permit to reduce impacts to fish and
wildlife resources.
1. Remaining wetlands and streams on the site should be protected from additional impacts
by placing them in a permanent conservation easement to prohibit filling, draining,
flooding, and excavation.
2. In order to minimize stream impacts, while retaining some measure of wildlife habitat,
we recommend a 100-foot undisturbed, native, forested buffer along perennial streams,
and a 50-foot buffer along intermittent streams and wetlands. Maintaining undisturbed,
forested buffers along these areas will minimize impacts to fish and wildlife resources,
water quality, aquatic habitat both within and downstream of the project area, and help
prevent the extirpation of endangered and threatened species In addition, wide riparian
buffers are helpful in maintaining stability of stream banks and for treatment of pollutants
associated with urban stormwater. Whereas, a grassed buffer, particularly fescue, is a
vegetated buffer but will not provide the necessary and highly valuable functions as
discussed for forested buffers.
3. Usc bridges for all permanent roadway crossings of streams and associated wetlands to
eliminate the need to fill and culvert. If culverts must be used, the culvert should be
designed to allow for fish passage. Generally, this means that the culvert or pipe invert is
buried at least one foot below the natural stroambed. If multiple cells are required, the
second and/or third cells should be placed so that their bottoms are at stream bankftlll
stage (similar to Lyonsfield design). 'This will allow sufficient water depth in the culvert
or pipe during normal flows to accommodate fish movements. If culverts are long, baffle
systems are required to trap gravel and provide resting areas for fish and other aquatic
organisms. If multiple pipes or cells are used, at least one pipe or box should be designed
to rurnain dry during normal flows to allow for wildlife passage. In addition, culverts or

pipes should be situated so that no channel realignment or widening is required,
Widening of the stream channel at the inlet or outlet of structures usually causes a
decrease in water velocity causing sediment deposition that will require future
maintenance. Finally, riprap should not be placed on the streambed.
4. Locate sewers and other utilities as fkr away from creeks as functionally possible and
minimize stream crossings. It is preferable that sewers be located outside the riparian
buffers.
The construction of roadways in new neighborhoods can produce short-term direct
impacts as well as long-term cumulative eflbcts. Increased stormwatcr runoff can
accelerate erosion of stream banks and scouring of the stream channel. Additionally, the
pollutants (e. 9,, sediment, heavy metals, herbicides, pesticides, and fertilizers) washed
from roads and urban landscapes can adversely affect and extirpate species downstream
of developed areas. Grassed swales in place of curb and gutter and on-site stormwalcr
management (i.e. bioretention areas) can be installed to produce no net change in the
hydrology of the watershed and are recommended. These designs often cost less to
install and significantly reduce environmental impacts from residential development.
Many of these recommondations have been applied in Maryland in efforts to protect the
Chesapeake Bay from water quality degradation.
