RE: Brighton Forest Subdivision — Phases III -A, V-A & IX -A
W&R No. 2020179.74
Dear Annette -
Please find attached one (1) copy of the proposed storm drainage construction drawings for Brighton
Forest Phases III -A, V-A, & IX -A. Please note these construction drawings are currently being reviewed
by Town of Fuquay-Varina and Wake County Sedimentation and Erosion Control. As we had previously
done with Phases 2A, 6B, 7B & 8B, we are forwarding plans for DWQ approval of the level spreader as
shown on Sheets 4 and 5 of the attached plans. The level spreader has been designed with an
engineered filter strip, a bypass diversion box and a rip rap dissipator pad. A by-pass channel is not
being proposed for the by-pass flow since the receiving area directly below the diversion box has an
average slope of 2.5%.
Also attached are copies of the level spreader design supplement sheets from DWQ and executed
Operation and Maintenance Agreement for the level spreaders in question.
Please note that this overall project has been slowed based on the economic conditions over the last
several years and has been completely phased to smaller sections. There is a 401 issued for this project
dated October 28, 2005 as DWQ project number 05-1701. The permitted wetlands impacts were
completed within the permit time limitations. Subsequent to that, additional phases have been and will be
developed that will discharge into adjacent Neuse River riparian buffer areas. We have also attached a
copy of the actual 401 Certification with the stormwater diffuse flow condition highlighted.
Please advise if you require additional information or have any questions concerning this request.
Sincerely,
I ,I .

Filter Strip, Restored Riparian Buffer and Level Spreader
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately after the filter strip is established, any newly planted vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
— Once a year, the filter strip will be reseeded to maintain a dense growth of
vegetation
— Stable groundcover will be maintained in the drainage area to reduce the
sediment load to the vegetation.
— Two to three times a year, grass filter strips will be mowed and the clippings
harvested to promote the growth of thick vegetation with optimum pollutant
removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and
may be allowed to grow as tall as 12 inches depending on aesthetic requirements
(NIPC,1993). Forested filter strips do not require this type of maintenance.
— Once a year, the soil will be aerated if necessary.
— Once a year, soil pH will be tested and lime will be added if necessary.
After the filter strip is established, it will be inspected quarterly and within 24 hours
after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County).
Records of operation and maintenance will be kept in a known set location and will be
available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

the proper design, installation and operation and maintenance of such Best Management Practices in
order to protect surface waters standards:
a. The erosion.and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and De#0 Manual, o
b. The design, installation, operation, and maintenance of the sediment and erosion control

including the desigu, installation, operation, and maintenance of sediment and erosion control Best
Management Practices, shall be performed so that no violations of state water quality standards,
statutes, or rules occur; I .
4. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent
practicable. If placement of sediment and a ' =ipn control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grate restored within six months of the date that the
Division of Land Resources has released the,project;
5. Protective Fencing - The outside buffer, wetland or water boundary and along the construction corridor
within these boundaries approved under this authorization shall be clearly marked with orange warning
fencing (or similar high visibility material) for the areas that have been approved to infiinge within the
buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15 NC;kC 2H,
Section .0500;
6. Deed Notifications - Deed notifications or similar mechanisms shall be placed on all retained

Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land
Resources (DLR) or a DLR delegate(] local erosion and sedimentation control program, an NPDES

8, Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles an
not altered. Existing stream dimensions (including the Cross section dimensions, pattern„ and
longitudinal profile) must be maintained above and below locations Of each Culvert. Culverts shall be
designed and installed to allow for aquatic life movement as well as to prevent head cutting of tile
streams. If any of the existing pipes are or become perched, the appropriate stream grade shall be re-
established or, if the pipes installed in a perched manner, the pipes shall be removed and re -installed
correctly.
Culvert(s) shall not be installed in such a manner that Will cause aggradation or erosion of the stream III)
or down stream of the culvert(s). Existing stream dimensions (including the cross section dimensions,
pattern and longitudinal profile) shall be maintained above and below locations of each Culvert.
Therefore, you must provide plans with adequate details that indicate that the current stability of the
stream will be maintained or enhanced. You must receive written approval from this Office' for the
above plans before the culvert(s) is installed. Culvert(s) must be installed according to approved plans.
Placement of culverts and other structures in waters, streams, and watlands must be placed Wow the
elevation of the streambed by one foot for all culverts with a diamatff gmatOr than 49 -inches, and 20
percent of the, Culvert diameter for culverts having a diameter less dM 48 inches, to allow low HOW
passage of water and aquatic life. Design and placement of culverts and other structures including
temporary erosion control measures shall not be conducted in a manner that May result In dis-
equilibrium of wetlands or stn beds or banks, adjacent to or upstream and down stream of ft- above
structures. The applicant is required to provide evidence that the equilibrium shall be maintained if
requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques must
be used where practicable instead of rip rap or other bank hardening methods. If rip -rap is necessary, it
shall not be placed in the stream bed, unless specifically approved by the Division of Water QualitY.
Installation of culverts in wetlands must ensure continuity of water movement and be designed
to adequately accommodate high water or flood conditions.
Upon completion of the project, the ,Applicant shall complete and return the enclosed "Certificate of
Completion" form to notify NCDWQ when all work included in the §401 Certification has been
completed. The responsible party shall complete the attached form and return it to the 401/Wetlands

EROSION CONTROL NARRATIVE
�THIS 18,09 -ACRE SITE IS LOCATED ALONG THE SOUTHEAST
SIDE OF JOHNSON POND ROAD IN SOUTHERN WAKE COUNTY.THIS PHASE WILL CONSIST OF 38 SINGLE-FAMILY LOTS AND
1,700 LINEAR FEET OF PUBLIC STREETS. RUNOFF FROM THIS
SITE IS TRIBUTARY TO MIDDLE CREEK IN THE NEUSE RIVER
BASIN. SEDIMENT RUNOFF IS TO BE CONTROLLED BY THE
USE OF SKIMMER BASINS, TEMPORARY DIVERSIONS, SILT
RES AS SHOWN ON THIS PLAN.
THERE IS NO FEMA FLOODPLAIN ON THIS PROPERTY IS
SHOWN PER FEMA FIRM MAP # 3720068800J AND
