I have reviewed the additional information for the U-5760 Merger screening proposal with reference to the section of
the road widening adjacent to Kerners Mill Creek.
I concur with your determination that the proposed road widening as defined by the provide plans would be the below
the threshold of impacts that the project could be verified under DA permit Nationwide Permit authorization. Therefore
I concur that Merger screening would not be necessary for the project as defined by your screening proposal.
However please be aware, that changes in the proposal that would include additional jurisdictional waters impacts that
raise impact totals above NWP verification thresholds could result in further review and possible determination of a
Merger screening review.

John and Dave,
At the end of the U-5760 External Scoping Meeting (9/21/16), we discussed Merger screening (a summary of that
discussion is below). At that time, we were unsure the level of impacts to a parallel crossing of a UT to Kerners Mill
Creek. Since that time, we have gathered more information and have developed some conceptual designs.
Our conclusion is that we are now below the IP threshold for the Kerners Mill crossing.
* Two conceptual designs are attached. They have the same typical section, but we investigated the constraints and
implications of different design considerations. Anticipated permanent impacts for the Kerners Mill system crossings
(the total for all crossings of Kerners Mill and the associated UTs) are:
o Alt 1: 130 LF of stream impact, 0.10 acre wetland impact
o Alt 2: 180 LF of stream impact
* We have avoided the parallel stream completely.
* There may be other stream impacts along the corridor, but this is applicable if you are looking at permit
thresholds per stream system (rather than cumulatively for the entire corridor).
* We may be able to further minimize impacts depending on the other design elements selected (median width,
sidewalks, bike lanes, etc.).
With these findings, NCDOT recommends that Merger is not needed for this project. Please let me know if this is
sufficient information to come to a conclusion about Merger for this project, or if you would like to meet (phone or in
person) to discuss further.
Thank you,
Teresa
Merger Screening Discussion Summary from 9/21/16:
Following the external scoping meeting, USACE, NCDWR, and NCDOT held a merger screening meeting. The total
potential stream impacts for 110-foot and 190-foot wide corridors were presented and discussed. The two stream
crossings at the interchange are proposed to be bridged; therefore, no impacts are anticipated at those locations. The
amount of impacts to the four potential stream impact areas near Timberwood Trail vary based on the typical section
proposed and the alignment. There are no known competing protected resources along the corridor.
The decision about Merger will be based largely on the likelihood of requiring an Individual Permit, although attendees
agreed that GP 13 may be appropriate. Since that determination will be affected by the selected typical section, the
merger screening team agreed to wait until the traffic forecast has been completed and typical section has been chosen
before a decision is made about whether to include this project in the merger process.
Ms. Gresham and Ms. Euliss said that if the project is not in Merger, NCDOT would coordinate with the permitting
agencies through the design process so that USACE and NCDWR were comfortable with the project purpose and
alternatives studied before NCDOT submitted the permit application.
