R -2519B Permit Drawing Review
The meeting began at 2:30pm with introductions initiated by Stephen Morgan ( NCDOT
Hydraulics). Meeting packets were distributed via the web prior to the meeting and
available by paper copy during the meeting.
General Comments and Discussion
USFW S asked if NCDOT was aware of the Stormwater Management Plan (SMP) that
had been implemented for all sections of the US 19 project. NCDOT was not aware of a
specific SMP for R -2519B that would supersede the present SMP developed during the
final design and permitting phase, but would investigate. Note: after the meeting, the
Biological Opinion (BO) was referenced. SMPs were developed for R- 2518A, R -2518B
and R -2519A but not R- 2519B. "....An ,SMP for R -25198 will be prepared during final
design for that section of the project... "
NCDOT stated the Stormwater Management Plan will reference site numbers in the final
version.
NCDOT reminded the group that as the review of each site progressed, any design
modification or revisions to hydraulic strictures would have to be minor. Any significant
changes need to be expressed during the hydraulic design review meeting (413) at which
time they could more easily be implemented.
Permit Drawing Review
The meeting then proceeded sheet by sheet for comments. Permit drawings were
displayed on audiovisual equipment for group discussion.
Sheet 4:
• No comments.
Sheet 6:
Impacts at Site 2A are near an existing 15" PVC on —Y4 -. The existing pipe will
be removed and replaced with 2 @30" RCPs. Site 2A will be added to the SMP.
Site 2 Little Crabtree Creek: The group discussed the impacts where the four
barrel culvert will be extended. The proposed culvert extensions are buried F and
have baffles in them. Floodplain benching will be used to direct low flow through
the center two barrels. An existing 18" CMP cross pipe is to be removed and
replaced with a storm drainage system that outlets to an armored base ditch
further from the creek. The existing cross pipe discharges directly to the creek.
The proposed ditch provides some treatment before discharging to Little Crabtree
Creek. There were no comments on this location in the previous 4B meeting
minutes.
Sheet 7:
• Site 3: JS UT213 has been added to the list of streams for the project. This is a
new site.
R -2519B Permit Drawing Review
Sheet 9:
There was some discussion about the Hazardous Spill Basin (HSB) /Dry Detention
Basin (DDB) located in the middle of the page right of station 84 +00. The basin
is constricted on the inlet side of an existing cross pipe that will be replaced, with
the outlet end of the cross pipe discharging to the South Toe River. NCDOT
noted the HSB was requested at the hydraulic design review (4B) meeting. The
basin will provide treatment where no treatment currently exists.
The group discussed how the septic drain fields right of station 92 +00 will be
removed. The septic tanks will be pumped out, collapsed and removed prior to
any earthwork.
Sheet 10:
• Site 4A is a new site.
Sheet 11/12:
• Site 5 South Toe River: NCDOT noted the bridge design and constriction had
been discussed at length in the office and on site, with the plans showing the
current span arrangement and impacts. The impacts shown are for the total
impacts of all constriction phases, with some impacts overlapping. The
constriction phasing is included in the permit drawings. Further discussion of
this site will be included in the SMP.
Site 5A will be discussed in the SMP. This site will also be included in the final
design plans with design dimensions and details. NCDOT noted this is an in -kind
stream replacement (148' for 148' of stream impacts) for no net loss. There will
be no morphological table with this site. The relocation will be of similar
dimension and profile. The stream will be stabilized with native vegetation and
monitored for stability. USFW S would like to make sure stream stabilization can
be ensured by language in the contract. The preference is for the stream to be
relocated prior to bridge constriction, with a minimum of one growing season
prior to project completion. Consultation with the contractor for this location was
requested by the resource agencies present. PDEA -NES will discuss proposals
before finalizing in the permit.
Site 6 involves culvert removal. This site would be eligible for stream restoration
and on -site mitigation. USACE will coordinate restoration ratios with PDEA.
DWQ would like information about the plants.
• The hazardous spill retention basin right of station 125 +00 will be designed to
have a dual function as a hazardous spill /dry detention basin.
• A match line will be added to designate the separation of sheets 11 and 12.
R -2519B Permit Drawing Review
Sheet 13:
Sites 7, 7A, 7B, 7C (Long Branch Creek) will be clarified and included in the
SMP.
Sheet 14:
• Site 8 will be expanded to include site 8B and 8C and will be clarified in the
SMP. 8B and 8C will be the two culverts. PDEA will discuss these sites with
USAGE.
• NCWRC would like to see baffles in the existing culvert. NCDOT Hydraulics
noted cross vanes and sills were used in the downstream direction of the culvert to
adjust the stream grade. Adding baffles would decrease culvert performance and
increase flooding potential and are therefore not recommended.
• USFWS asked if the 36" pipe was connected through the side of the proposed
culvert. NCDOT Hydraulics said it was and is designed as such to dissipate
energy.
• USACE noted skewed culverts can present a problem with maintaining normal
depth flow at the outlet due to the relationship of the baffles to the culvert
geometry. Such low flow conditions are not suitable for fish passage. PDEA NES
commented that cross vanes or other stricture can be added downstream of
culverts to maintain suitable low flow conditions when warranted.
Sheet 16:
• At the beginning of sheet 16, right of station 177 +30, the rip rap will be drawn
more accurately to show it does not enter the stream.
Site 11 NCWRC prefers the pipe to angle toward the stream where it turns north.
NCDWQ does not like the 90 degree bend. NCDOT Hydraulics commented that
the pipe size is being increased therefore decreasing velocities and to realign the
pipe would create more stream impacts. Having the rip rap bank stabilization
allows the contractor to fix any sort of erosion problems that may exist and have a
better transition from pipe outlet to existing stream dimensions. The team
decided to keep the pipe outlet as shown.
Sheet 17:
• Site 13 showed part of the wetland being impacted by fill. The team agreed the
remainder was so small and likely would be impacted so the entire wetland
feature will be shown as a total take.
Sheet 18:
• Site 18: A drainage outlet previously shown at the 4B meeting right of station
215 +00 has been removed to avoid impacts to the historic property.
R -2519B Permit Drawing Review
Sheet 20/21:
• Site 20: The small wetland will be a total take. USACE and PDEA will discuss
the stream relocation (Site21) to determine mitigation requirements.
• Site 22 Big Crabtree Creek: No comment
• Site 23: Rip rap has been eliminated from the upstream side of the cross pipe as
requested at the 4B meeting. The dry detention basin right of station 251 +00 is
receiving drainage from sheet 22 where existing eroded outlets have been
abandoned.
• A match line will be added to the sheet to designate the separation of sheets 20
and 21.
Sheet 22 (no impacts):
• The SMP will discuss abandoning four badly eroded existing outlets and using a
pipe system to discharge through the dry detention basin right of station 251 +00
on sheet 21.
Sheet 23:
Site 24 has a small ditch at the outlet of the storm drainage system as requested in
a previous 4B meeting.
Sheet 24:
As requested at the 4B meeting, the 54" pipe at Site 25 was angled toward the
stream.
Sheet 25:
• The team discussed the stability of the short ditch between the two pipes at Site
26 (Non JS stream). The ditch detail will be changed to include rip rap.
Sheet 26:
• Site 29 (Brushy Creek): The fish ladder detail will be added to the permit
drawings. The existing culvert will be retrofitted with sills and baffles. The
tributary will be relocated to a new culvert at station 324 +00 (Site 30). This
stream relocation was the preferred alternative from the 4B meeting.
Site 30 will include the culvert. All of parcel no. 154 will be purchased and used
for stream restoration and floodplain preservation. There will be a planting plan
for this site. The plants will be similar to existing vegetation. The stream
relocation details will be part of the final design plans. Morphological table will
be included in SMP.
Site 31 will include temporary impacts on the upstream side of the culvert due to
watercourse management for the downstream extension.
R -2519B Permit Drawing Review
Sheet 27 (no impacts):
• (Non JS stream) Left of station 335 +00 the outlet of the storm drainage system
goes into a junction box for energy dissipation and outlets at an angle per request
in the 4B meeting.
Sheet 28:
• Site 33: Right of station 350 +00 a small open channel was added downstream of
the 24" pipe per requested in the 4B meeting.
Site 34: After the building adjacent to the stream is removed the stream banks will
be re- graded to a more stable section upstream of the culvert. The site will then
be placed in right -of -way.
Sheet 29:
• Site 35 is a new site added since the 2004 field verification.
• There is no Site 36.
• Site 37: The junction box and pipe stub -out right of station 367 +00 will be
reconfigured to a straighter alignment to the receiving stream. The note "flush out
ditch" will be removed from the plans.
Sheet 30:
• No comments
Sheet 31:
• Sites 39 and 40 are new sites added since the 2004 field verification.
Sheet 32:
• Site 42: Right of station 409 +50 a spring box was added as requested in the 4B
meeting.
Sheet 33;
• The drainage feature shown right of station 414 +50 is non jurisdictional but had
inadvertently been hatched as an impacted site. The hatching will be removed.
Sheet 34:
Site 45: The concrete ditch replacement (with rip rap) will be shown as a non -
mitigable permanent impact. Per USCACE, there is "no net loss ".
