Robert,
FYI, their response is below.

Hi Dave,
Stormwater BMP measures were considered upstream of Site 1, but ultimately we were unable to utilize them due to
topographical, geographical, right of way, and environmental concerns.
Topographical/Geographical: Upstream of the proposed culvert extension/additional on the west side, there is an
existing draw, which discharges just upstream of the existing culvert. Due to the height of the proposed roadway
embankment, the existing swale is filled by the proposed fill slope.Just upstream of this existing draw is an existing
jurisdictional feature. This jurisdictional feature did not afford us the room to fit a stormwater measure and provide an
adequate discharge prior to the buffer. It was requested by NCDOT personnel to avoid impacts to the buffer and pipe any
roadway drainage to the culvert.
Right of Way:Due to current development to the west of the culvert extensions, right of way was limited in this area. The
areas to the west are being developed with commercial, industrial, and residential zoning.

Environmental:After drainage was originally designed and approved, we received comments from Nicole Thomson
during review of the wetland permit drawings/erosion control plans about discharging into and through the buffer at
both culvert locations. It was requested to eliminate all ditches through buffers, even if we were replacing existing draws.
Our original design incorporated a short run of swale through the buffer, tying to the existing 72"RCP, impacting BZ-2. If
stormwater BMP's had been utilized, we had concerns about how to discharge treated water through the buffer without
having adverse effects.
Hopefully this provides the clarification you needed on the stormwater question. Please let us know if we can provide
anything else.
Thank you,
Nancy

You mean to inquire if they could provide some treatment through the buffer, instead of tying directly into the
culvert?

Dave—My only comment is to ask them to look at any way to provide treatment or dispersed flow into the buffer for
the new pipes tying directly into the new box culverts at site 1.Thanks.

Hi Robert,
When you get the chance, please take a look and let me know if you see anything relative to the SMP that
needs to be addressed. No BMPs,just some pipes. U-6010 is not a Merger project.
Thanks.
