Hi Alan,
I have attached the revised impact table.
Thanks,

Hi Crystal,
I have received responses to your questions and have listed their answers below in red.
- will the construction corridor be maintained at 40' within the entire project corridor, or at least in wetland and
stream impact areas, or was the revision only at stream impact locations?
The construction corridor will not be maintained at 40' along the entire project. Where the proposed alignment
crosses wetlands and streams we will add notes to address the need to limit the construction corridor to 40' at
those select locations.
- If stream impacts have been revised then there should be revised plans that reflect those changes. Please provide the
revised plans.
They should have the revised plans by Monday
- Krysta's previous request for additional information she requested clarification on the project purpose. You indicated
the following: "The purpose of this project is to increase sewer capacity to this area. The existing sewer line will be left
in place and remain active and the new sewer line will be installed parallel to the existing line." The PCN provides the
2

following information regarding the purpose: "The Lower Coddle Creek Interceptor project involves installing a new
sewer line running along Coddle Creek. The proposed sewer line will be placed next to an existing deteriorating sewer
line that will be abandoned. This project will provide for future wastewater needs in Cabarrus County." This
information is contradictory. Can you please clarify if the old line will be abandon or if it will remain active
They new sewer line will run parallel to the existing sewer, and the existing one will remain in place and active.
-Assuming that the most recent information is correct and that the line is to increase capacity; what is the need for the
increase in capacity? Is the line being constructed to service existing residential development or is it being built to
service new development that is coming to the area?
The Water and Sewer Authority of Cabarrus County (WSACC) needs to install a parallel large diameter
sanitary sewer main in order to provide additional capacity for the existing sanitary sewer main. Anticipated
industrial development at the old Philip Morris plant and population growth within Cabarrus County are the
drivers for this project
-And lastly, typically with utility line projects, there should be information identifying what each end of the line is tying
in to in order to establish a single and complete project and better understand the purpose. As such, please provide
some information on the end and beginning points of the sewer line and why this line is a single and complete project
in itself.
At the downstream end of the project, reconfiguration of the existing sewer is required to accommodate the
connection of the proposed 48-inch sewer. The connection points, as shown on sheet SS-2 and SS-3, tie into
two existing manholes which combine sewer flow at a downstream 60-inch main. Additionally, the two
existing manholes will need to be removed and replaced within the same position due to internal corrosion and
the expense associated with coring into the manhole wall to make the new pipe connections.
The upstream connection point will require the installation of a diversion structure (labeled #105 on plan sheet
SS-31) over top of the existing 30-inch sanitary sewer main. The diversion structure will allow WSACC to set
a weir elevation in which sanitary sewer flow will be diverted from the existing 30-inch main into the proposed
36-inch main. This will provide capacity relief to the existing 30-inch main. As part of the installation of the
diversion structure, the 30-inch main extending from the diversion structure to the existing manhole 010288
upstream will be removed and replaced with a 36-inch diameter pipe in order to match the existing sewer main
size upstream of manhole 010288
Let me know if you need anything else.
Thanks,
Megan Bollero

Hi Crystal,
I will reach out to the engineer to get these questions answered and I will get back to you. In regards to the
Schweinitz's sunflower I wanted to see if you wanted us to coordinate with USFWS or if you wanted to.
Thanks,

Hi Megan,
I've reviewed the original submittal and the new information provided and I do have a couple more
questions.
It looks like that subsequent to meeting with Alan on site, the construction corridor was reduced to just 40'
wide. This is consistent with NWP 58 which requires work corridors to be no more than 40' unless
justification for a larger corridor is provided. With the additional information you provided revised stream
impact tables to reflect these changes. My questions/comments are as follows:
1. will the construction corridor be maintained at 40' within the entire project corridor, or at least
in wetland and stream impact areas, or was the revision only at stream impact locations?
2. If stream impacts have been revised then there should be revised plans that reflect those
changes. Please provide the revised plans.
Regarding the purpose of the projects:
1. Krysta's previous request for additional information she requested clarification on the project
purpose. You indicated the following: "The purpose of this project is to increase sewer capacity to
this area. The existing sewer line will be left in place and remain active and the new sewer line will
4

be installed parallel to the existing line." The PCN provides the following information regarding the
purpose: "The Lower Coddle Creek Interceptor project involves installing a new sewer line running
along Coddle Creek. The proposed sewer line will be placed next to an existing deteriorating sewer
line that will be abandoned. This project will provide for future wastewater needs in Cabarrus
County." This information is contradictory. Can you please clarify if the old line will be abandon or
if it will remain active.
2. Assuming that the most recent information is correct and that the line is to increase capacity; what is
the need for the increase in capacity? Is the line being constructed to service existing residential
development or is it being built to service new development that is coming to the area?
3. And lastly, typically with utility line projects, there should be information identifying what each end
of the line is tying in to in order to establish a single and complete project and better understand the
purpose. As such, please provide some information on the end and beginning points of the sewer line
and why this line is a single and complete project in itself.
The PCN you previously submitted to Krysta indicates that there is suitable habitat for the Schweinitz's
sunflower within the project corridor, that surveys were done for the sunflower during the optimal survey
window and no plants were found and as such, that the project may affect, but is not likely to adversely
affect the Schweinitz's sunflower. I agree with this assessment and as such, I need to conduct informal
consultation with FWS to ensure they concur with the not likely to adversely affect determination. The
information indicates that the survey was conducted on October 21, 2020. Can you provide a copy of that
survey report for me to forward to FWS?
Let me know if you have any questions regarding this email and feel free to give me a call if you'd like to
discuss anything further.

Hello All,
I just wanted to make sure everyone received the additional information I sent for the Lower Coddle Creek
Interceptor project (SAW-2021-00521) on April 30 and see if I could get clarification as to which USACE
PM is handling this project.

Permanent wetland impacts are the result of converting forested wetland to herbaceous
for the utility -line maintenance easement.
