APR 1 7 2012
Please find attached one (1) copy of the proposed storm drainage construction drawings for Brighton
Forest Phase 7B 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
Phase 66 we are forwarding plans for DWQ approval of the level spreader as shown on Sheets 4 and 7
of the attached plan The level spreader has been designed with an engineered filter strip and a bypass
channel in accordance with current DWQ requirements
Also attached are copies of the level spreader design supplement sheets from DWQ calculations
regarding the proposed stormwater bypass channel and executed Operation and Maintenance
Agreement for the level spreader 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

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 line 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 10 inch (or 15 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

Sediment and Erosion Control
2 Erosion and sediment control practices must be in full compliance with all specifications governing
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 Design Manual
b The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor -owned or leased borrow pits associated with the project
c Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times
3 No waste spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the
footprint of the impacts depicted in the 404/401Permit Application All construction activities
including the design, 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
4 Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent
practicable If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed and the natural grade 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 condor
within these boundaries approved under this authorization shall be clearly marked with orange warning
fencing (or similar high visibility material) for the area that have been approved to infringe within the
buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15 NCAC 2H
Section 0500
6 Deed Notifications - Deed notifications or similar mechanisms shall be placed on all retained
jurisdictional wetlands waters and protective buffers in order to assure compliance for future
wetland, water and buffer impact These mechanisms shall be put in place prior to impacting any
wetlands, waters and/or buffers approved for impact under this Certification Approval and
Authorization Certificate A sample deed notification can be downloaded from the 401/Wetlands Unit

7 Construction Stormwater Penmt NCG010000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land
Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an NPDES
General stormwater permit (NCGO10000) administered by DWQ is automatically issued to the
project This General Penmt allows stormwater to be discharged during land disturbing construction
activitiestas stipulated by conditions in the permit If your project is covered by this permit
[applicable to construction projects that disturb one (1) or more acres] full compliance with permit
conditions including the sedimentation control plan, self monitoring record keeping and reporting
requirements are required A copy of this pertrut and monitoring report forms may be found at
httn 11h2o err state nc Mg/s4 /Forms Documents htm
8 Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles are
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 the
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 up
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 wetlands must be placed below the
elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20
percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow
passage of water and aquatic life Design and placement of culverts and other shuctures including
temporary erosion control measures shall not be conducted in a manner that may result in dis
equilibrium of wetlands or streambeds or banks adjacent to or upstream and down stream of the 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 np rap or other bank hardening methods If np 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" fora 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/Wethmds

Certificate of Completion form.
9 DifIbse Flow (No Review)
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
won- emsive velocities through the protected stream, buffars such that it will not re concentrate before
discharong into a stream as identified within Y SA NCAC 2B 0233 (5) If thus is not possible, it may
be necessary to provide stormwater facilities that are considered to remove nitrogen. This may require
additional approval from this Office
10 Upon completion of all work approved within the 401 Water Quality Certification or applicable
Buffer Rules, 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
