APPROVAL of Neuse River Buffer Rule (15A NCAC 02B .0233) Authorization Certificate

And

Waiver of 401 Water Quality Certification

Dear Mr. Mallard:

You have our approval, in accordance with 15A NCAC 02B .0233 and any conditions listed below, to
impact approximately 8,312 fe of Zone 1 and 4,050 ft2 of Zone 2 of the protected riparian buffers for the
purpose of constructing The Knolls At The Neuse at the subject property as described within your
application dated April 8, 2005 and in additional correspondence (a fee check for $200.00) rcceived April
20, 2005. In addition, you should obtain or otherwise comply with any other required federal, state or
local pennits before you go ahead with your project including (but not limited to) Erosion and Sediment
Control, Non-discharge other regulations.

Your application materials for a 40 1 Water Quality Certification to impact up to 144 feet of perennial
streams at the subject property was received in the Division of Water Quality's Central Office on April 13,
2005. According to our rules [15A NCAC 2H .0507 (A)], if final action is not taken within 60 days, the
Certification is waived unless DWQ has objected in writing to your application. Therefore, DWQ has
waived the requirement for a 401 Water Quality Certification for your plans to impact waters as described
in your April 8, 2005 application materials, including the stormwater management plan. However, if
additional impact occurs or your development plans change, this waiver is no longer valid and a 401 Water
Quality Certification will be required.

This Neuse River Buffer Rule approval is 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. If the property is sold, the new owner must be given a copy of this authorization and
approval letter and is thereby responsible for complying with all conditions. This approval requires you to
follow the conditions listed below.

The Additional Conditions of the Authorization are:

1. Impacts Approved

The following impacts are hereby approved as long as all of the other specific and general
conditions of this Authorization are met. No other impacts are approved including incidental
impacts:

Amount Approved Plan Location or Reference
(Units)
Buffers 12,363 (square ft.) PCN form

2. Diffuse Flow

All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non-erosive velocities through the protected stream buffers such that it will not re-concentrate
before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not
possible, it may be necessary to provide stormwater facilities that are considered to remove
nitrogen. This may require ad9itional approval from this Office.

3. Buffer Impacts

The approved buffer impacts associated with the road crossing equal 12,363. The Neuse Buffer
Rule requires buffer mitigation for road crossings that exceed 150 linear feet or 1/3 acres of buffer
impacts. The impact area includes the area of the footprint of the use and any clearing and grading
activities within the riparian buffer necessary to accommodate the use. The length of buffer impact
is measured parallel to the stream and includes the length of the footprint of the use and any clearing
and grading activities within the riparian buffer necessary to accommodate the use. If the DWQ
detennines that the impacts exceed 150 feet or 1/3 acre to the buffer, then buffer mitigation pursuant
to 15A NCAC 02B .0233 will be required for the entire impact area.

4. Deed Notifications

Deed notifications or similar mechanisms shall be placed on all retained protective buffers in
order to assure compliance for future buffer impact. These mechanisms shall be put in place prior
to impacting any buffers approved for impact under this Certification Approval and Authorization
Certificate. A sample deed notification can be downloaded from the 401/Wetlands Unit web site
at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be
modified as appropriate to suit to this project.

5. Certificate of Completion

Upon completion of all work approved within this authorization, and any subsequent
modifications, the applicant is required to return the attached certificate of completion to the
401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center,
Raleigh, NC, 27699-1650.

Any disputes over detenninations regarding this Authorization Certificate (associated with the approved
buffer impacts) shall be referred in writing to the Director for a decision. The Director's decision is
subject to review as provided in Articles 3 and 4 of G.S. 1508. This Authorization Certificate shall
expire five (5) years from the date of this letter.

proposed crossing. The roadway crossing was designed to allow a perpendicular impact.
Sediment traps will be placed outside of the wetlands and buffer and the wetlands will be clearly
flagged and marked to avoid unnecessary impact.

VllI. Mitigation

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to

Page 9 of 12

freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.

USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.

If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for US ACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
incomplete. An applicant may also choose to review the current guidelines for stream restoration
in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
http://h20,enr,state,ne,us/newetlands/strmgide.htm!.

1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.

LEVEL SPREADER OPERATION AND MAINTENANCE AGREEMENT (SPREADERS 1 & 2)
The Knolls at the Neuse, Johnston County

The level spreader is defined as an elongated, level threshold, designed to diffuse stormwater runoff.

Maintenance activities shall be performed as follows:
1. After construction and until vegetation has been established, level spreader(s) shall be inspected after
every rainfall. Thereafter, level spreader(s) shall be inspected at least every month and more
frequently during the fall season and after heavy rainfall events.
a. Accumulated sediment, leaves, and trash shall be removed, and repairs made if required.
b. Inspect level spreader(s) for evidence of scour, undercutting, settlement of the structure, and
concentrated flows downhill from the level spreader(s).
c. A level elevation shall be maintained across the entire flow-spreading structure at all times.
Repair or replace the level spreader if it is damaged.
d. Repair eroded areas and replace/replant dead or damaged vegetation.
2. The contractor should avoid the placement of any material on and prevent construction traffic across
the structure. If the measure is damaged by construction traffic, it shall be repaired immediately.
3. Mow vegetative cover to a height of six (6) inches.
4. Remove plants when they cover half of the level spreader surface to prevent obstruction.
5. Inspect and repair the collection system (e.g., catch basins, pipes, swales, riprap) four (4) times a year
to maintain proper functioning.

I acknowledge and agree by my signature below that I am responsible for the performance of the
maintenance procedures listed above. I agree to notify OWQ of any problems with the system or prior to any
changes to the system or responsible party.

Subject: Johnston County
TIle Knolls at the Neuse

Please find attached a PCN Application submittal package for the subject project. The application is for a
residential subdivision roadway crossing with 144 If of riparian buffered stream impact with 0.0 I acres of
wetlands impact.

TIlis submittal is for the roadway crossing in Phase I of the project. TIlere are also two utility crossings
proposed in this phase that we wish to be considered as "exempt." Both the proposed 4" waterline and
the 8" sewerline will impact less than 40 feet of buffer when installed and will have a maintenance
corridor of less than 10 feet each. TIle sewerline would have to be installed at depths of approximately 40
feet or more in some areas to avoid the crossings. The waterline crossing is required by the Johnston
County Department of Public Utilities to provide a "looped" waterline to improve water service through
the subdivision. To minimize impact, both crossings are proposed as perpendicular and the buffered areas
will be protected with appropriate erosion control measures, including silt fence and rip rap stream
crossing protection as required by Land Quality. TIle layout of the streets in future phases will not impact
the remaining buffer on site (no proposed roadway crossings), so there are no anticipated future permits
required for this site.

TIle attached I "=50' site plan shows all proposed impacts by this roadway crossing, including fill slopes,
culverts, and dissipater pads. I have also included full size drawings of the proposed crossing, of the
layout of the infrastructure in this phase, and of the proposed overall street layout of the subdivision.
DWQ - Level Spreader Worksheets, Q 1 0 calculations, and an executed operation and maintenance
agreement for the two proposed level spreaders at the roadway crossing are included in the package. A
detail sheet that shows a detail for the level spreader is also attached.

Your earliest review and approval is greatly appreciated. Please feel free to contact me if you have any
questions or need additional information.

Sincerely,

1M t -tiMMJr '

GENERAL NOTES:
GRADE-THE GRADE OF THE LAST 20 FEET OF DIVERSION CHANNEL
SHOULD PROVIDE A St.fooTH TRANSIllON FROM CHANNEL GRADE
TO LEVEL AT THE SPREADER. THE GRADE OF THE SPREADER
SHOULD BE O%.

SPREADER UP- CONSTRUCT THE LEVEL UP ON UNDISTURBED SOIL
TO UNIFORM HEIGHT AND ZERO GRADE OVER THE LENGTH OF THE
SPREADER. PROTECT IT WITH AN EROSION RESISTANT MATERIAL, SUCH
AS FIBERGlASS MA11NG, TO PREVENT EROSION AND ALLOW VEGETA110N
TO BECOME ESTABLISHED.

OUTLET AREA-THE OUTLET DISPOSAL AREA MUST BE GENERALLY SMOOTH
AND WELL VEGETATED WITH A MAXIMUM SLOPE OF 10~

VEGETATE ALL DISTURBED AREAS.

CONSTRUC110N SPECIFlCA 110NS:
1. THE MATTING SHOULD BE A MINIMUM OF 4fT WIDE EXTENDING 6 INCHES
OVER THE LIP AND BURIED 6 INCHES DEEP IN A VER11CAL TRENCH ON
THE LOWER EDGE. THE UPPER EDGE SHOULD BUTT AGAINST SMOOTHLY CUT
SOD AND BE SECURLY HELD IN PLACE WITH CLOSELY SPACED HEAVEY DUTY
WIRE STAPLES AT LEAST 12 INCHES LONG.

2. ENSURE THAT THE SPREADER LIP IS LEVEL FOR UNIFORM SPREADING
OF STORM RUNOFF.

3. CONSTRUCT THE LEVEL SPREADER ON UNDISTURBED SOIL (NOT ON FILL).

4. CONSTRUCT A 20-FT TRANSIllON SEC110N FROM THE DIVERSION CHANNEL
TO BLEND SMOOTHLY TO THE WIDTH AND DEPTH OF THE SPREADER,

5. DISPERSE RUNOFF FROM THE SPREADER ACROSS A PROPERLY STABALlZED
SLOPE NOT TO EXCEED 10"" MAKE SURE THE SLOPE IS SUFFICIENTLY SMOOTH
TO KEEP flOW FROM CONCENTRA 11NG.

6. 1M MEDIA TEL Y AFTER ITS CONSTRUC110N, APPROPRIA TEL Y SEED AND MULCH

CONSTRUCTION SEQUENCE

Obtain grading permit.
Install gravel construction pad.
Begin clearing and grubbing. Maintain devices as needed.
Install temporary sediment trap (TST) and diversion ditches to route
flow to Tsis Immediately after on area Is cleared.
Rough grade site.
Install storm sewer and protect inlets with silt
fencing, sediment traps or other approved measures as shown
on the plan. Begin construction.
Stabnize site as areas are brought up to finish grade with
vegetation, paving, ditch linings, etc.
When construction is complete and all areas are stabilized
completely, call for inspection by Environmental Inspector.
If site is approved, remove temporary diversions, silt
fencings, sediment basins, etc., and seed out or pave any
resulting bare areas. All remaining permanent erosion
control devices (such os velocity dissipators) should be
installed now.
When vegetation has become established, call for final site
inspection by Environmental Inspector.
