Dear Roman Acosta:
Attached hereto is a copy of Certification No. WQC006600 issued to Roman Acosta and KB Homes, dated
February 12, 2024. This approval is for the purpose and design described in your application. The plans
and specifications for this project are incorporated by reference as part of this Water Quality Certification.
If you change your project, you must notify the Division and you may be required to submit a new
application package with the appropriate fee. If the property is sold, the new owner must be given a copy
of this Certification and is responsible for complying with all conditions. [15A NCAC 02H .0507(d)(2)].
This Water Quality Certification does not relieve the permittee of the responsibility to obtain all other
required Federal, State, or Local approvals before proceeding with the project, including those required
by, but not limited to, Sediment and Erosion Control, Non -Discharge, Water Supply Watershed, and
Trout Buffer regulations.
This Water Quality Certification neither grants nor affirms any property right, license, or privilege in any
lands or waters, or any right of use in any waters. This Water Quality Certification does not authorize
any person to interfere with the riparian rights, littoral rights, or water use rights of any other person
and does not create any prescriptive right or any right of priority regarding any usage of water. This
Water Quality Certification shall not be interposed as a defense in any action respecting the
determination of riparian or littoral rights or other rights to water use. No consumptive user is deemed
by virtue of this Water Quality Certification to possess any prescriptive or other right of priority with
respect to any other consumptive user.

CONDITIONS OF CERTIFICATION [15A NCAC 02H .0507(c)l:
ACTIVITY SPECIFIC CONDITIONS OF CERTIFICATION [GC4256]:
1. Any additional impacts to streams and/or wetlands as a result of future roads, buildings, driveways,
utility lines or other development related activities within the development, or future phases of the
development, may be considered cumulative to impacts approved in this Certification and may require
a modification of this 401 Water Quality Certification approval.

Justification: 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.
2. 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.

surface waters or wetlands downstream, continue to support existing uses during and after project
completion. 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.
14. If the project is covered by NPDES Construction Stormwater Permit Number NCG010000 or NPDES
Construction Stormwater Permit Number NCG250000, full compliance with permit conditions
including the erosion & sedimentation control plan, inspections and maintenance, self -monitoring,
record keeping and reporting requirements is required.

Justification: A project that affects waters shall not be permitted unless the existing uses, and the
water quality to protect such uses, are protected. Activities must not cause water pollution that
precludes any best use on a short-term or long-term basis. As cited in Stream Standards: (12) Oils,
deleterious substances, or colored or other wastes: only such amounts as shall not render the
waters injurious to public health, secondary recreation, or to aquatic life and wildlife, or adversely
affect the palatability offish, aesthetic quality, or impair the waters for any designated uses, and
(21) turbidity in the receiving water shall not exceed 50 Nephelometric Turbidity Units (NTU) in
streams not designated as trout waters and 10 NTU in streams, lakes, or reservoirs designated as
trout waters, for lakes and reservoirs not designated as trout waters, the turbidity shall not exceed
25 NTU; if turbidity exceeds these levels due to natural background conditions, the existing turbidity
level shall not be increased. As cited in Wetland Standards: (c)(1) Liquids, fill or other solids, or
dissolved gases shall not be present in amounts that may cause adverse impacts on existing
wetland uses, and (3) Materials producing color or odor shall not be present in amounts that may
cause adverse impacts on existing wetland uses.
15. All work in or adjacent to streams shall be conducted so that the flowing stream does not come in
contact with the disturbed area. Approved best management practices from the most current
version of the NC Sediment and Erosion Control Manual, or the NC Department of Transportation
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams, and
other diversion structures shall be used to minimize excavation in flowing water.

17. 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.

contact between uncured or curing concrete and waters of the state. Water that inadvertently
contacts uncured concrete shall not be discharged to waters of the state.

temporarily disturbed areas shall be restricted to the area directly impacted by the approved
construction activity. All rip -rap shall be placed such that the original streambed elevation and
streambank contours are restored and maintained and shall consist of clean rock or masonry
