Approval of 401 Water Quality Certification and Authorization Certification per the Neuse River
Buffer Protection Rules (15A NCAC 2B.0233) with Additional Conditions
Dear Ms. Hanchette,
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 8 linear feet of perennial stream (temporary), 0 acres of wetland, 1,714 ft2 of
Zone 1 and 979 ft2 of Zone 2 of the protected riparian buffers for the purpose of constructing the
residential development on the site, as described within your Pre-construction Notification Application
dated November 10, 2010 and received by DWQ on November 12, 2010. The impacts are covered by
General Water Quality Certification Number 3821 (GC3821). General Certification 3821 allows you to
use Nationwide Permit NW29 when issued by the US Army Corps of Engineers (USACE). In addition,
you should obtain or otherwise comply with any other required federal, state or local permits before you
go ahead with your project including (but not limited to) Erosion and Sediment Control, and Non-
discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application shall expire upon expiration of the 404 Permit.
This approval is for the purpose and design that you described in your PCN application (November 10,
2010). If you change your project, you must notify us and you may be required to send us a new
application. If the property (or a lot on the property) is sold, the new owner must be given a copy of this
Certification and approval letter and will thereby responsible for complying with all conditions. If total
fills for this project (now or in the future) exceed one acre of wetland or 150 linear feet of stream,
compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h). This approval
requires you to follow the conditions listed in the attached Water Quality Certification (GC3821)
and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general
conditions of this Certification (and Isolated Wetland Permit) are met. No other impacts are

404 Wetland 0 acres November 10, 2010 PCN Wetland Impacts
Riparian buffer Zone 1 1,714 (square feet November 10, 2010 PCN Buffer Im acts
Riparian buffer Zone 2) 979 (square feet November 10, 2010 PCN Buffer Impacts
2. No Waste, Spoil, Solids, or Fill of Any Kind
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 Pre-Construction Notification and authorized by this
approval letter. 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.
3. No Sediment and Erosion Control Measures in Wetlands and Waters
Sediment and erosion control measures shall not be placed in wetlands or waters without prior
approval from the Division. If placement of sediment and erosion control devices in wetlands
and waters is unavoidable, design and placement of temporary erosion control measures shall not
be conducted in a manner that may result in dis-equilibrium of wetlands or stream beds or banks,
adjacent to or upstream and down stream of the above structures. All sediment and erosion
control devices shall be removed and the natural grade restored within two (2) months of the date
that the Division of Land Resources or locally delegated program has released the project.
4. 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. 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. 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.
Construction Stormwater Permit NCGO 10000
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 Permit allows stormwater to be discharged during land disturbing
construction activities as 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 permit and monitoring report forms may
be found at http: //portal. ncdenr. org/web/wq/ws/su/npdessw#General Permits NPDES.
6. Stormwater Management Plan:
a. The proposed wet detention pond discharging to the level spreader-riparian buffer system shall
be designed to meet 90% TSS removal as described in your application. The wet pond shall be
Lennar Carolinas, Inc.
Page 3 of 5
November 15, 2010
approved by the DWQ or the City of Raleigh prior to any impacts in this phase of the project
occurring.
b. If the wet detention pond design information submitted with your application is approved by the
City of Raleigh without any changes, then you are required to submit an approval letter from the
City along with a notarized operation and maintenance agreement for the wet detention pond.
c. If there are any changes required by the City of Raleigh in the design information for the wet
detention pond, you must submit the City's approval letter along with the complete stormwater
management information including the design calculations, plan sheets as well as the operation
and maintenance agreement for the proposed wet detention pond.
7. Diffuse Flow
All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected
stream buffers and will not re-concentrate before discharging into the stream as identified within
Neuse River basin Buffer Rule 15A NCAC 2B .0233(5).
In an effort to comply with the diffuse flow provisions of the Buffer Rule you have provided the
DWQ with SMP (sheet #s PD-1 to PD-5 with revision date August 24, 2010) having a 23-ft
concrete level spreader device that receives flow from a wet detention pond. The proposed level
spreader then disperses the concentrated flow through the downstream riparian buffer. The DWQ
believes that, if implemented as per the August 24, 2010 plans, the diffuse flow requirement will
be achieved. At no time shall stormwater from other areas of the proposed development be piped
directly through the buffer without prior DWQ written authorization.
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 infringe within the
buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A
NCAC 2B .0233 and GC 3821.
9. 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 at the time lots or properties are recorded. A
sample deed notification can be downloaded from the 401/Wetlands Unit web site at
http://portal.ncdenr.org/web/wq/swp/ws/401/certsandpermits/apply/forms. The text of the sample
deed notification may be modified as appropriate to suit to this project.
10. Notification of Construction
The applicant and/or authorized agent shall contact the DWQ Express Review Program in writing
at the letterhead address within ten (10) days of the commencement of construction.
11. Certificate of Completion
Within thirty (30) days of the 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 Oversight/Express Review
Permitting Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh,
NC, 27699-1650.
The applicant/permittee and their authorized agents shall conduct all activities in a manner consistent with
State water quality standards (including any requirements resulting from compliance with §303(d) of the
Clean Water Act), and any other appropriate requirements of State and Federal Law. If the Division
Lennar Carolinas, Inc.
