Subject: \[Non-DoD Source\] Brunswick County US-17 Bus.Old Ocean HWY Pipe Replacement
Brad and Joanne,
We have proposed modifications to the proposed pipe replacement on US-17 Bus. in Brunswick County which was
originally authorized for burial waiver under Action ID # SAW-2019-01782 and DWR Project No. 20191220. In order to
meet current safety standards with the existing lack of shoulder and steep drop off, our new pipe is proposed 15.7’
longer than our existing pipe. Keeping a 3% slope, this will put us approximately at grade with the elevation that our
surveyor picked up approximately 100’ downstream. We will still need to construct a riprap flume since the pipe will still
be physically perched above the existing blowhole (unable to obtain elevations at deepest areas), but we are proposing
to keep this under 4 LF so that our overall stream channel impacts will be less than 20 LF. Please let me know if you see
any issues with these proposed modifications.
Hope you all are staying safe and healthy!
