Meeting Summary
The field review meeting was held at the request of DMS in order to view as -built conditions on
this recently constructed Design -Bid -Build site, and identify any concerns heading into the project
monitoring phase.
This project recently got updated via a request from DMS to the IRT dated 9/9/2019, to update
the monitoring period from 5 years to 7 years, outline updated monitoring requirements and
performance standards, and introduce a formal credit release schedule. Project construction
officially closed on 8/13/2019, subsequently had a monitoring contract awarded, and is currently
undergoing baseline monitoring features set up. Mitigation success monitoring will be started in
2020 (MY01), and the MYO report should be made available in late January 2020.
The following is a summary of the field review and items discussed during the meeting:
• The group met at the wet crossing on project Tributary A, and briefly discussed the project
status and recent history. It was noted that a monitoring firm had recently been awarded
a contract and that the baseline monitoring feature installation would begin on
11/12/2019. Hard copies of the official designer as -built record drawings and a DMS
proposed monitoring features map were distributed by DMS.
• The group walked to the upstream end of the project (STA 100+00); the group then
walked to the neighboring property upstream of the project to understand the nature of

the offsite stream and how it might be influencing onsite project streams. The IRT noted
that during a previous mitigation plan review visit there had been concern about the
offsite stream cutting into the project area across the right floodplain, but stream
hydrology currently appears to be flowing into the project area in a more favorable
orientation, with a possible oxbow forming (offsite). The geolift/riffle structure from STA
100+00 TO 101+00 installed as a post -hurricane Florence (Sept. 2018) storm repair
appeared to be performing well and moving sediment through the system while
protecting the stream banks adequately thus far.
• Walking downstream to the bridge crossing on Glade Creek School Road, the stream
appeared to reflect the record drawings and no major concerns were noted on Little Pine
Creek or Tributary A. The boundary is well marked, and flood flows were evident on the
left floodplain from an overbank event approximately 10 days earlier. The floodplain sills
and associated brush material appeared to be intact and performing well.
• The group moved farther downstream across the roadway and bridge, where DMS noted
that a breakaway electrified cattle rope along a wet crossing adjacent to Glade Creek
School Road had become entangled with a white pine branch and ripped loose (likely
during the recent overbank event). DMS indicated that the landowner is expected to fix
the fence and that he had been contacted.
• The group moved farther downstream towards STA 112+00 and the confluence of
Tributary B with Little Pine Creek. All structures appeared to be intact and performing as
installed. Tributary B was observed.
• The group walked along the right floodplain of Little Pine Creek to the downstream limits
of the project. In general, there were no major issues noted, and all structures were intact
and performing well but DMS and IRT agreed that floodplain woody vegetation did not
seem very dense in areas, despite post -construction bare root planting at 605 stems/acre.
Floodplain soils in some areas are gravel and cobble -dominated, where floodplain flows
are moving sediments during overbank events. It was noted that vegetation density will
be monitored closely upon receipt of the MYO baseline report and vegetation data, and
supplemental planting will occur in the next dormant season if initial stem counts are poor.
There were some concerns with the standing water in the vernal pool on the right
floodplain near STA 113+50; while there had been a recent overbank event that likely
filled the pool, ideally the vernal pools should not hold water for extended time periods.
The IRT noted that planting of aquatic vegetation in the pools would improve these
features in the event that they hold water longer than preferable. The other three vernal
pools farther downstream were not holding water during the site visit.
• DMS asked the IRT to observe preservation Tributaries E and F (two small wetland 2B
tributaries that merge together near the edge of Little Pine Creek), since the lower section
of Tributary F has appeared to down cut somewhat since project design. Tributaries E and
F (50 LF and 153 LF, respectively) were jurisdictionally confirmed during the design stage.

The IRT indicated that, despite some stable segments of Tributary F upstream of the head
cut, that recent impacts and a head cut along Tributary F have affected stream
performance on these reaches to the degree that they should not yield stream
preservation credits. DMS indicated that the upcoming MYO baseline report would reflect
no mitigation crediting for preservation on Tributaries E and F.
• The group walked upstream through Wetland 2B and inspected the boundary marking
along Wetland 2B. The entire length of preservation Tributary D (655 LF) was walked,
flow was evident, and no major concerns were noted. DMS noted where the conservation
easement contained the spring source and entire headwater feature on Tributary D. The
group walked into the floodplain of Tributary C (restoration tributary totaling 578 LF). The
adjacent enhancement wetland 2A appeared wet and the IRT seemed fine with the
mapped location of the enhancement wetland gauge, although a more ideal location 10-
15 feet closer to Tributary C was agreed on; if changed, the installed gauge will reflect this
updated location and will be noted in the baseline report. Tributary C was observed and
no major concerns were noted, other than the thick herbaceous vegetation making
visibility of bare root plantings difficult.
• Other than the minor location adjustment of the wetland 2A gauge, there were no
requested changes to quantities or locations of any monitoring features/devices (as
communicated in the 9/9/2019 update memo and monitoring map provided by DMS to
IRT).
• The meeting concluded with DMS indicating their intention to post the MYO baseline
report when it is finalized, and discuss the project accordingly at the next credit release
meeting.
