AUTHORIZATION of Jordan Lake Water Supply Watershed Riparian Buffer Protection
Rules (Watershed Protection Ordinance Section 304(,1) 4 and 15A NCAC 2B .0267)
Authorization Certificate
Project Name: Briar Chapel Force Main and Re -use Waterline
Dear Mr. Meyers,
You have our authorization, in accordance with the Chatham County Watershed Protection
Ordinance and any conditions listed below, to temporarily impact approximately 2,214 ft2 of the
protected riparian buffers associated with Pokeberry Creek and its wetlands for the purpose of
installing a 14" sanitary sewer forcemain and a 12" re -use waterline as described within your
application submitted March 9, 2018 and revised on March 21, 2018, and on the provided Buffer
Impacts Maps. Impacts for this project are limited to the inner and outer portions of Zone 2 and
will consist of a 20 -ft wide by 65 -ft long clearing within the buffer for placement and operation
of bore and jack equipment. Impacts to the riparian buffers are minimized and will only occur
on the western side of Pokeberry Creek. Crossing of Pokeberry Creek and its associated
wetlands will utilize two (2) existing 16" encasement pipes that were previously installed;
therefore, no direct impacts to surface waters is anticipated. Both encasement pipes extend
beyond the eastern limits of the riparian buffers therefore all activities, including bore and jack
equipment, will be located outside of the eastern buffers.
Following the completion of construction activities, the 20 -ft wide by 65 -ft long clearing within
the riparian buffer will be stabilized with a native permanent seed mix in accordance with the
Permanent Seeding Schedule provided on Sheet 18 of the approved Construction Drawings and
Sediment & Erosion Control Plans. All excavated areas within the riparian buffer are proposed
to be returned to existing conditions and contours. Per your application this review and
authorization is only valid for those impacts stated above. In addition, you should obtain or
otherwise comply with any other required federal, state or local permits before you proceed with
your project including (but not limited to) Erosion and Sediment Control and Non -discharge
regulations.
This authorization certification is for the purpose and design that you described in your
application. If you change your project, you must notify us and you may be required to send us a
new application. If the property is sold, the new owner must be given a copy of this
authorization letter and is thereby responsible for complying with all conditions. This
authorization requires you to follow the conditions listed below.

BUFFER IMPACT NARRATIVE

I. INTRODUCTION
The proposed development is for approximately 16,300 linear feet of 14" sanitary
sewer forcemain and 13,800 linear feet of 12" re -use waterline. The project will begin
at the SD East lift station, continue north along Highway 15/501 before turning west
to follow along Taylor Road, continuing along Catullo Run, where it turns west to cut
across Pokeberry Creek. It continues along the northern edge of a section of Briar
Chapel Subdivision and eventually terminating on the northern side of the existing
wastewater treatment plant, owned and operated by Old North State Water
Company.
The general topography of the project area is mixed, with elevations ranging from
392' to 561' above mean sea level. The highest point of the route is near the
wastewater treatment plant while the low point is at the crossing of Pokeberry Creek.
The project area is composed of several different land covers including impervious
surfaces, open space and wooded areas. Soils in the planned route include Chewacla
and Wehadkee (Cha), Helena Sandy Loam (HeC), Udorthents (UdC), and Wedowee
Sandy Loams (WdC, WdE, WeB, WeC, WeD, and WeE). The project area falls
within the FEMA Flood Insurance Rate Maps 3710976500K, 3710977500K and
3710977400J. A portion of the project lies within the floodplain of Pokeberry Creek.
There are three areas where the forcemain and re -use waterline construction will
cross existing buffers. For the two intermittent buffers, the proposed boring will span
the entire buffer underground and there will be no disturbance in the actual stream
buffers, therefore these areas will not require permitting through Chatham County.
In Buffer Impact Area 1, where the lines cross Pokeberry Creek the encasement pipes
end in the outer 50' of the 100' buffer (Zone 2), therefore this is the only area where
with disturbance that could require mitigation. The impacted area is to be replanted
by the contractor and will be regarded as a temporary impact. This stretch is
approximately 65 linear feet of trenching located in Zone 2, therefore it will fall into
the "allowable" category on the mitigation determination sheet.

II. DETAILED PROJECT OVERVIEW
The project starts at a proposed pump station located in the SD East Commercial
Center within the Briar Chapel Development. The disturbance for the area where the
pump station is located was previously permitted through Chatham County by
McKim and Creed. Once the forcemain reaches the edge of the SD East
Development, it will be installed under 15/501 via an existing 24" steel encasement
pipe that was previously permitted through the NCDOT encroachment process.
Throughout this run of the project, the existing erosion control measures for the SD
East development will be utilized along with the temporary mulch tubes on the
downhill side of the excavation.
From there the project makes its way along Highway 15/501, Taylor Road and Catullo
Run. At the intersection of Highway 15/501 and Taylor Road, the project picks up
the proposed 12" Re -use Waterline. It will connect with the existing re -use waterline
that was previously permitted through Chatham County and the NCDOT. Both of
the lines will be installed in the same trench but will be separated vertically by 15".
The approximate trench width is 7.5'. Along this section of the project, temporary
mulch tubes will be utilized on the downhill side of the excavation. Where the
forcemain and re -use waterline are installed in the centerline of existing roadside
ditches, temporary wattles will be used in -lieu of stone check dams to reduce
velocities in the disturbed swales.
After the project crosses under Catullo Run (via jack and bore), it goes across raw land
that is currently owned by Briar Chapel and is planned to be a residential
development. This parcel has a 100' buffer that runs along the southern property line
and the mains will run just to the north of that undisturbed buffer. There are two
buffer crossings in this section, one of which is to be permitted through Chatham
County. Due to the location of Pokeberry Creek as well as a branch that both span the
entire property, both must be crossed to accomplish the goal of the project. The first
crossing over the branch of Pokeberry, an Intermittent Buffer, is located a few
hundred feet into the property west of Catullo Run. Both mains will be installed via a
jack and bore operation. The borings will span the entire width of the buffer;
therefore, the buffer will be entirely undisturbed, therefore will not require
permitting. Buffer Impact Area 1 is the crossing of Pokeberry Creek. There are two
(2) existing 16" encasement pipes, that run the entire width of the existing wetland,
that will be utilized at this location. The mains will reduce outside of the wetland to

a pipe size that will fit the existing encasement pipes. In utilizing the existing
encasement pipes, the disturbance is limited. The only buffer impacts that will occur
outside of the encasement pipe crossings will be in the outer Zone 2 buffer on the
west side of Pokeberry Creek, as the existing encasement pipes end 50' outside of the
wetland boundary. From there, the mains will be installed outside of the Pokeberry
Creek buffer and under Great Ridge Parkway. This impacted area is to be replanted
and maintained as a requirement in to the contractor, therefore the impact is
considered temporary. The permanent seeding schedule is located on the erosion and
sediment control details in the construction plans. All this section of the project will
utilize the temporary mulch tubes on the downhill side of the disturbance.
The next section of the project will be installed behind some existing residences and
outside of any buffered area, except one unavoidable crossing behind the lots on Old
Piedmont Circle. Due to the existing lot layout, there is no option to direct the route
of the lines around the buffer. This is an Ephemeral buffer crossing along this section
and the mains will be installed via jack and bore under the entire buffered area. Thus,
there will be no disturbance inside the buffer and this location will not require
permitting either. Along the buffer, watercourse buffer fence will be utilized for
erosion control. In all other areas, temporary mulch tubes will be installed along the
downhill side of excavation. A section of the installation will encroach into the
backyards of several existing homes. There is an existing easement that the proposed
installation will be fully within and Newland will coordinate the construction
activities with the current homeowners.
The final stretch of the project will cross under a Duke Energy Transmission Line
easement near the new tennis facility for Briar Chapel and down the north side of the
wastewater treatment plant effluent pond.

Avoidance and Minimization
Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project.
When selecting the route for the forcemain and re -use waterline, avoiding buffer crossing was a main
consideration, however the crossing of Pokeberry Creek was inevitable when connecting the pump
station to the wastewater treatment facility. The buffered areas in the route were avoided as much as
possible. Bore and jack construction will be utilized to eliminate impacts at two buffer crossings by
spanning the entire buffer underground, with bore pits located outside of the buffers. At the Pokeberry
creek crossing, there are existing encasement pipes which the proposed lines will pass through. On the
western side of the creek is the only location where there will be trench construction of the forcemain and
re -use waterline in buffered area, outside of underground encasement pipes. This area is to be replanted
by the contractor therefore is considered temporary.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques.
The utility crossings will be constructed using bore and jack methods to minimize impact in each of the
impact areas.
