Brandon,
That raingage has been discontinued because the funding was not renewed. There are no plans to
bring the site back online.

Hey Jason,
I just wanted to email you regarding the USGS 354616081085145 RAINGAGE AT OXFORD RS NR
CLAREMONT, NC. Will the daily precipitation data for this rain gage continue to be updated on the
new website starting in 2023 or is this gage completely offline now? If the latter is true (gage is
indefinitely offline) can you point me to a rain gage close to this one that will continue to function
and update the daily precipitation data?
Thanks for the help,
Brandon Romeo | Environmental Scientist

Meeting Notes
The meeting began at 12:30 pm. Aaron presented an overview of the site conditions and issues noted in the
AMP, MY1, and MY2 reports. From there, the group walked upstream to the headwaters of UT1, retraced steps
and reviewed UT1, UT1A and the BMP downstream of the road. The meeting concluded at 3:00 PM.
1.Opening Remarks
Aaron noted that portions of this site had been replanted twice as part of the AMP and that a 200 LF
section of dry channel on UT1 Reach 1A was observed last week for the first time.
Kim asked if we thought fescue in the easement affected bare root survival. Sam replied that the
fescue areas within the easement did not line up the low stem counts. The majority of fescue within
the easement occurs near the culvert crossing between UT1 Reach 1B and 2. These areas have been
ring sprayed and will continue to be monitored and treated.
Kim asked if this site contained ground water gages in wetlands to monitor functionality. Brandon
replied that two gages were installed in delineated wetlands and Aaron clarified that they were not tie
to success criteria.
2.Specific Items of Discussion
Upstream of road
o Kim asked why UT1 Reach 2 was not proposed for restoration given the erosion and incision.
Aaron and Paul acknowledged that the reach was borderline, but E2 was chosen since erosion and

incision were sporadic. No additional work was done during construction because most of the
reach flowed through a large wetland which was not permitted for impacts under the NWP 27.
Wildlands will monitor the at-risk areas with additional phot points.
o Casey asked if the failing veg plot near station 114+00 was replanted. Sam confirmed that it was.
o Kim noticed some bare areas along the right fenceline and suggested that Wildlands keep eyes on
them.
o Casey and Erin asked about the presence of algae in the stream and expressed concern about in-
stream vegetation. Wildlands replied that algae was most likely due to long, slow pool sections
and the lack of shade. Once live stakes grow tall enough to shade the channel, the presence of
algae could decrease. Wildlands plans on treating in-stream vegetation in June.
o Kim asked if the design called for wider pool sections that were observed in the field because that
was not apparent in the monitoring reports. Wildlands responded that pools were designed to be
30% wider than riffles. Winter photos will be included in subsequent monitoring reports, so the
channel dimension is more visible (this will be done site-wide when the channel is not visible).
o Olivia asked if the wetland near station 111+60 RT ever dried up. Sam and Brandon confirmed that
they have never seen it dry.
o Kim suggested that a transect be added near station 109+00 to monitor veg since it seemed bare.
Wildlands confirmed a transect would be added.
o Casey requested that any repairs on piping structures (both identified in MY2 report and new
instances) be discussed in the subsequent monitoring repot.
o The IRT asked Wildlands about the path forward for the 200 LF of dry channel on UT1 Reach 1A
(station 103+50 – 105+50). Wildlands responded that they will discuss this section internally to
develop an approach to determine the cause(s) of absence of baseflow. The approach could
include additional flow gages or groundwater wells and taking a closer look at the bounding grade
control structures functionality. Kim suggested installing a game camera in the dry section to
visually monitor flow conditions. Wildlands agreed.
o Kim suggested installing additional live stakes near the upper extents of UT1 Reach 1A where
sedimentation has occurred. Wildlands agreed.
Downstream of road
o Aaron pointed out that while the preservation reach does have some eroded banks and incision, it
has not changed significantly since pre-project conditions. Kim agreed with preservation to avoid
impacting the mature wooded buffer.
o Casey asked if aggradation at the beginning or UT1 Reach 4A coincided with the fallen tree.
Wildlands confirmed that was the case and suspected that aggradation would lessen once tree
was removed. Aaron noted that the channel width had not changed through the aggradation
section.
o Erin asked if the area near station 142+50 was replanted. Sam confirmed. Kim said that in general,
all replanted areas (especially within wetlands) need mobile plots or transects. Brandon confirmed
that 5 mobile plots have been added since baseline and transects will be added where needed.

ALEXANDER FARM Mitigation Site – IRT Meeting Notes
o Kim asked if additional monitoring years were added due to replanting. Aaron replied that per the
AMP, Wildlands will conduct an extra year of vegetation monitoring in MY6. If the data doesn’t
suggest that vegetation performance towards success, and additional year of monitoring may be
required in MY8.
o Kim suggested adding a photo point to monitor failed lunker log at UT1 station 151+10 since the
bank appears to be stable. Wildlands agreed.
o Kim asked about the condition of the linear wetland at the downstream end of the project.
Wildlands explained that it delineated as a wetland and drains pasture runoff. It was not impacted
during construction. Kim suggested that a winter photo point be added to the linear wetland
feature. Wildlands agreed.
3.Closing Remarks
Kim remarked that there were several invasives, including cattail and paulownia, that need to be
treated. Wildlands confirmed that some invasives have already been treated this year and additional
invasives will be treated in the upcoming months.
Kim and Paul requested that the linear footage and % of total length of the dry section of channel be
included in the minutes. The dry section is approximately 200 LF and constitutes approximately 4.7%
of the stream credits. The dry section is noted on the attached figure. Wildlands plans on discussing an
approach internally.
The IRT agreed to release the MY2 (2021) credits as proposed.
