Justification: A project that affects waters shall not be permitted unless the existing uses, and the water
quality to protect such uses, are protected. In determining that the proposed activity will comply with
state water quality standards (including designated uses, numeric criteria, narrative criteria and the
state's antidegradation policy), the project must provide for replacement of existing uses through
compensatory mitigation.
2) Stormwater Plan Approval by Local Government
Because the stormwater management plan approved by a local government, the Town of Cary, is being
used to meet stormwater/diffuse/dispersed flow requirements on this project, you are required to submit a
digital copy of the approved stormwater management plan (SMP) including plan details on scaled plan
sheets with proof of the local government's approval. The approved SMP shall be submitted to Colleen
Cohn of the DWR 401 and Buffer Permitting Branch ([e-mail]) before any impacts
authorized in this certification occur. After it is approved, the SMP may not be modified without prior
written authorization from the local government. If modified, a digital copy of the approval letter and the
modified SMP shall also be submitted to the DWR 401 & Buffer Permitting Branch (at the email address
above or using the electronic Supplemental Information Form) prior to the commencement of the
modifications.

Justification: In order to protect against impairment of water quality standards and best usage of
receiving and downstream waters, water quality based management practices must be employed to
protect against direct or indirect discharge of waste or other sources of water pollution. Surface water
quality standards require that conditions of waters be suitable for all best uses provided for in state rule
(including, at minimum: aquatic life propagation, survival, and maintenance of biological integrity,
wildlife, secondary contact recreation, agriculture) and that activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. In determining that the proposed activity will
comply with state water quality standards (including designated uses, numeric criteria, narrative criteria
and the state's antidegradation policy), the Division must evaluate if the activity has avoided and
minimized impacts to waters, would cause or contribute to a violation of standards, or would result in
secondary or cumulative impacts.
3) If this Water Quality Certification is used to access residential, commercial or industrial building sites,
then all parcels owned by the permittee that are part of the single and complete project authorized by this
Certification must be buildable without additional impacts to streams or wetlands.

Justification: In order to protect against impairment of water quality standards and best usage of
receiving and downstream waters, water quality based management practices must be employed to
protect against direct or indirect discharge of waste or other sources of water pollution. Surface water
quality standards require that conditions of waters be suitable for all best uses provided for in state rule
(including, at minimum: aquatic life propagation, survival, and maintenance of biological integrity,
wildlife, secondary contact recreation, agriculture), and that activities must not cause water pollution
that precludes any best use on a short-term or long-term basis.
17) In -stream structures installed to mimic natural channel geomorphology such as cross -vanes, sills, step -
pool structures, etc. shall be designed and installed in such a manner that allow for continued aquatic life
movement.

18) Culverts shall be designed and installed in such a manner that the original stream profiles are not altered
and allow for aquatic life movement during low flows. The dimension, pattern, and profile of the stream
above and below a pipe or culvert shall not be modified by widening the stream channel or by reducing
the depth of the stream in connection with the construction activity. The width, height, and gradient of a
proposed culvert shall be such as to pass the average historical low flow and spring flow without
adversely altering flow velocity. If the width of the culvert is wider than the stream channel, the culvert
shall include multiple boxes/pipes, baffles, benches and/or sills to maintain the natural width of the stream
channel. If multiple culverts/pipes/barrels are used, low flows shall be accommodated in one culvert/pipe
and additional culverts/pipes shall be installed such that they receive only flows above bankfull.
Placement of culverts and other structures in streams shall be below the elevation of the streambed by one
foot for all culverts with a diameter greater than 48 inches, and 20% of the culvert diameter for culverts
having a diameter less than or equal to 48 inches, to allow low flow passage of water and aquatic life. If
the culvert outlet is submerged within a pool or scour hole and designed to provide for aquatic passage,
then culvert burial into the streambed is not required.
For structures less than 72" in diameter/width, and topographic constraints indicate culvert slopes of
greater than 2.5% culvert burial is not required, provided that all alternative options for flattening the
slope have been investigated and aquatic life movement/connectivity has been provided when possible
(e.g. rock ladders, cross -vanes, sills, baffles etc.). Notification, including supporting documentation to
include a location map of the culvert, culvert profile drawings, and slope calculations, shall be provided to
DWR 30 calendar days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required, provided that there is
sufficient documentation of the presence of bedrock. Notification, including supporting documentation
such as a location map of the culvert, geotechnical reports, photographs, etc. shall be provided to DWR a
minimum of 30 calendar days prior to the installation of the culvert. If bedrock is discovered during
construction, then DWR shall be notified by phone or email within 24 hours of discovery.
Installation of culverts in wetlands shall ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions. When roadways, causeways, or other fill
projects are constructed across FEMA-designated floodways or wetlands, openings such as culverts or
bridges shall be provided to maintain the natural hydrology of the system as well as prevent constriction
of the floodway that may result in destabilization of streams or wetlands.
The establishment of native woody vegetation and other soft stream bank stabilization techniques shall be
used where practicable instead of rip -rap or other bank hardening methods.
