Chris,
I feel as though that stream will have baseflow throughout most of the year

Jeff,
Yes. If there is any base flow, we will have to use a pump around operation which would maintain the flow
downstream. By building the coffer dam, there will be no running water through the work area which would eliminate
any sediment downstream.

I should add that there is still no guarantee. They may still request surveys — I'm just trying to minimize the potential.

I believe it would, however, would it be preferable to use the silt bags and maintain some discharge in lieu of stopping
flow with a cofferdam?

Thanks, Kevin:
I'll run with this. For context though (and its USFWS, not us), the concerns are two -fold. First is containing any potential
sediment. Second is maintaining hydration of any potentially suitable areas downstream.
Jeff — you know the area pretty well. Would you feel confident the stream would continue to flow downstream during
installation?

Jeff,
The stream crossing will likely not be able to be performed in the dry unless the base flow is very low during
implementation. The current plan would be to place a coffer dam upstream of the work area and allow the stream to
back up during the installation. The pipe section should be able to be completely laid in one day. If the base flows are
too high to allow the water to back up, the stream flows will be pumped through silt bag and allowed to discharge below
the work area. The pipe and wingwalls should be able to be installed in no more than 2 working days. Let me know if
you need anything else from me on this.

Jeff:
I'm writing up the project description for USFWS. It typically helps if I can say that if work cannot be done in the dry, a
stream pump -around or similar means of protecting downstream reaches during construction would be employed. I
should have asked this initially — but does this project propose anything like that?

Colleen,
Please see the responses to your questions below and attached.
1. SOA attached
2. We did not proposed a rip rap dissipator since the pipe was buried 12". There will be some rip rap inside the
wing wall area but not 20 feet downstream.
3. Cross Section of the Culvert is shown on Sheet CE-04
4. Approved JoCo Buffer Permit attached.
Let me know if you have further questions. Thank you

Hi Jeff,
1' beginning my review, and in order to complete the review, some additional information is required:
1. A Statement of Availability from a private mitigation bank was not included for the 0.389ac of wetlands impacts.
Please provide a Statement of Availability. [15A NCAC 02H .0502(c)]
2. Does the 106 linear feet of stream impact include a rip rap dissipator? [15A NCAC 02H .0502(c)]
3. Please provide a cross section of the culvert. [15A NCAC 02H .0502(c)]
4. It appears that this parcel falls under Johnston County's delegated authority for Neuse Riparian Buffers. Please
provide confirmation that buffer impacts will be submitted to Johnston County for authorization or supporting
documentation that this project is outside of Johnston County's delegated authority. [15A NCAC 02H .502(c)]
