Subject: Div 3 Field Scoping Meeting for Onslow 11 and Onslow 13
Location: Onslow 11 and Onslow 13 Bridge Sites
9
Attendees: See attached Sign-In Sheet (provided By NCDOT)
A field scoping meeting was held for each of the Subject bridges on-site. The following items were
discussed:
General
• The Field Scoping Meeting Worksheet for each bridge site was reviewed in the field by all present.
NCDOT will complete each worksheet based on the field review and provide to all attendees.
• An individual MD Estimate will be created for Onslow 11 and one for Onslow 13 and each project
is anticipate to have its own Purchase Order.
• Milestone Dates for the two sites are as follows:
o Right of Way January, 2018
o Permits February 2018
o Let Apri12018
• NCDOT will provide final surveys for each site. NCDOT will provide survey schedule to RS&H for
review. Survey can be accelerated if necessary.
• At each bridge site NCDOT will survey the creek for at least 100' upstream and downstream of the
bridge and will pick up the top of banks on either side of the creek and the bottom of creek.
• Wetlands have been delineated by NCDOT. A Microstation file will be provided for each bridge
with wetland boundaries.
• NCDOT will perform Geotechnical services at each bridge site. Resident Engineer AI Edgerton will
provide approved Bridge Survey and Hydraulic Design Report to Dean Argenbright (NCDOT
Geotech) once he receives from Jon Moore (NCDOT Hydraulics).
• RS&H will utilize its subconsultant for utility relocation plans. Utilities present include Duke Power,
Time Warner Cable (TWC), Century Link and ONWASA. It is anticipated relocation will take 3 to 4
months for Century Link and 6 to 8 months for Duke Power. RS&H will obtain a contact with Duke
Power and TWC, and Steve Davis (NCDOT) will provide a contact for Century Link. Matt Padgett is
the contact for ONWASA.
• Modified Method III Clearing to be utilized (slope stake plus 5 ft).

• SR 1434 will be closed at each site during construction of each bridge. Traffic will utilize an off-site
detour route. NCDOT (Brady Fisher) will drive detour routes to see if any improvement is
necessary to roadway or bridges.
• Each bridge typical section is anticipated to be 33'-0" Out to Out with a 27'-10" clear roadway
width.
• No deck drains on bridges. Widen bridge to accommodate spread if necessary.
• Main channel streams on both bridges are Public Trust Waters and subject to CAMA buffers (30
ft)
• Entry points for any bores to be shown on utility plans. Bores will be kept out of CAMA buffers.
• Design Exceptions will be allowed if necessary to prevent excessive roadway work since these are
bridge replacement projects.
• NCDCM will require MP-1, MP-5, and possible MP-3 forms to document bridge construction,
utility relocation, and bank stabilization.
• 404/401 permitting will follow the Low Impact Bridge Replacement procedures.
• Environmental documentation will be a Low Impact Bridge Replacement Attachment G.
• Historic & archaeological responses will be included with the permit applications.
• NCDOT and agencies would prefer rip-rap specifications that don't allow marl.
• NCDCM will determine if NCDMF can use any of the existing bridge material for artificial reefs.
Utility relocations need to comply with CAMA General Permit conditions, and profiles of bores will
be shown along with any impacts on a separate impact sheet from the bridge replacement
impacts.
• All existing and old piles and structure should be completely removed at each site, unless it is
rotten and excessive disturbance will occur to the stream/wetland during removal and in that
event it will be cut off at the creek bed.
Onslow 11
• No in-water moratorium exists for Onslow 11.
• The proposed bridge will consist of 18" or 21" Cored Slab Units with 1 span at 45' and 1 span at
35'. The proposed left abutment (as looking downstream) will be set back 5' from the existing
abutment.
• Survey along roadway will be provided for at least 300' off each end of bridge and for at least 20'
outside of existing R/W on each side.
• If bridge is superelevated so that deck drains to the upstream side of the bridge it may require
the use of a flume at the end of the bridge instead of a DI. It is desired to carry a normal crown
section across the bridge if possible and then utilize a DI on each side of the bridge which outlet
on downstream side of bridge.
• Onslow County Roadway Maintenance Supervisor Brady Fisher said there are no known flooding
issues at this site.
• Only the primary stream channel has 30 ft CAMA buffers. Small tributary channel upstream does
not.

Onslow 13
• An in-water moratorium exists for Onslow 13 from February 15 to June 30.
• RS&H will set the bridge length for NCDOT review once NCDOT provides the final survey. The toe
of slopes will be set 5' to 10' off the top of banks as feasible. The bridge will consist of 3 spans
and no bents are to be placed in the creek. The minimum bridge length will be 100'.
• RS&H will examine providing a 90 degree skew bridge and its impact to the stream bank running
adjacent to the roadway on the left downstream corner. If this arrangement has a negative impact
to the stream bank RS&H will layout a skewed bridge to eliminate or minimize the impact as
much as possible.
• The existing abutment and the remains and remnant piles from the previous bridge will be
completely removed from beneath the left side approach span. The existing hole under the left
side approach span will be filled with rip rap to the floodplain elevation on either side of the
bridge. Areas outside the bridge will be filled and vegetated to tie into existing ground.
• NCDOT to provide limits of survey for RS&H review.
• Property owner on left upstream side of bridge noted that water once rose up and flowed
between two dogwood trees in his front yard but did not reach his house.
• One private driveway exists in the proximity of the bridge that will have to be accounted for in
traffic control plan.
