Subject:Perquimans 12 and 17
Garcy,
We looked at this option, but the elevations would likely create some issues for us. The drop inlet will fall to an elevation
close to the adjacent wetland and then drain out a pipe, through the shoulder. If we cut the swale back to the wetland,
it will actually draw water from the wetland to the drain line. If the road was higher and we had more fill associated with
this project, we could probably get the flow to move towards the wetland. However, at this site, it doesn’t look like it
will work. I am sure with this low area the proposed swale, will become vegetated with wetland plants over time and
provide some pretty good treatment.
I believe on Perquimans 17, we can eliminate one of the swales. I modified the wetland line on that drawing and will be
sending you and tracey some updated permit drawing sheets.
Thanks,
Clay

Subject: Pasquotank Bridge 12

Clay,
I reviewed your application for the replacement of Bridge 12 in Pasquotank Co. in the field yesterday. The plans call for
creating a swale at the outlet of the stormwater discharge point in the NE quadrant (site #3) and carrying the water
straight to the stream. There is no existing ditch in that quadrant now and the water from the roadway currently
sheetflows off the shoulder and drains into the adjacent wetland at a low point.

Would it be possible to redirect the swale away from the stream to this low point and let the water drain into the
wetland? This would provide more opportunity for treatment. Let me know what you think. Thanks.
