RE: R-5311A
Chris,
Based on the information provided and my knowledge of the project area, we would not object to the proposed
1:1 mitigation ratio for the projected impacts for this section of the project. However: there are many other potential
wetland impacts associated with other phases of the project. This ratio would not be acceptable for those impacts.
Mitigation ratios for any impacts outside of those shown on the attachments to your earlier email would need to be
addressed separately. Tracey

Subject: [EXTERNAL] R-5311A
Tracey,
We are looking to lower the mitigation ratio for this project. I believe you are familiar with it and have worked or are
working on the JD. Below is the reasoning behind the proposal and the request and the documentation is included.
R-5311A is located in Hertford County and has a June 2017 LET. The project consists of an interchange at NC 11 and
Short Cut Road and a grade separation at NC 11 and Modlin Hatchery Road. The impacts for this project are an
estimated 12 acres of low quality, non-riparian wetland with most of the impacts occur at the interchange. These
impacts should be reduced as the project design is completed. A large portion of the wetlands is maintained by mowing
with the remainder being a 7-10 year old clear cut. Due to the poor quality of the wetlands and the fact that a large
portion is mown, NCDOT is proposing a 1:1 ratio for mitigation for this project. NCWAM forms were completed for each
wetland at the interchange. There wasn't one done for the grade separation. There are, however, wetland rating forms
for each wetland. The DWQ wetland rating form scores each wetland at the intersection as 16 out of 100. The NCWAM
rates the wetlands as low.

Therefore, given the reasons stated above, NCDOT respectfully requests a 1:1 ratio for the impacts associated with R-
5311A.
Please let me know your thoughts and if an on-site meeting is required. Thanks for your help.
