1. Background Information
DMS requests to update the Little Pine Creek II Restoration Project from a 5 -year, non-credit release
monitoring term to a 7 -year, credit release term to become better aligned with more recent project
monitoring and credit release schedules.
This project, a DMS design -bid -build project originally instituted in December 2007, has had several
delays due to landowner issues, a temporary ban on trout waivers (2010), a construction contract
termination and design reassignment (2013), conservation easement adjustment (2015), mitigation
plan addendum (2016) and significant hurricane damage during construction (2018). The project was
built according to the January 2016 mitigation plan addendum design (Wildlands Engineering), and
now has a final, LSS-sealed as -built survey dated July 14, 2019; it is currently under advertisement for
post -construction monitoring services (firm to be determined via bidding process).

2. Performance Standards
Performance criteria from the October 24, 2016 USACE Public Notice guidance will be followed and
are outlined as follows:
Restored Stream Channels
1. All streams must maintain an Ordinary High -Water Mark (OHWM), per RGL 05-05.
2. Continuous surface flow must be documented each year for at least 30 consecutive
days.
3. Bank height ratio (BHR) cannot exceed 1.2 for all measured cross sections on a given
reach.
4. Entrenchment ratio (ER) must be above 2.2 for all measured riffle cross-sections on
a given reach (for C and E streams).
5. BHR and ER should not change by more than 10% in any given year for all measured
cross sections on a given reach.
6. Must document occurrence of at least 4 bankf ill events in separate years during the
monitoring period.
Riparian Ve-etg ation
1. Within planted portions of the site, a minimum of 320 stems per acre must be present
at year 3; a minimum of 260 stems per acre must be present at year 5; and a minimum
of 210 stems per acre must be present at year 7.
2. Trees must average 6 feet in height at year 5, and 8 feet in height at year 7 (mountain region).
3. Planted and volunteer stems are counted, provided they are included in the approved
planting list for the site.
4. Any single species can only account for 50% of the required stems per monitoring
Plot.
3. Monitoring Plan
A MYO baseline report and as built record drawings will be provided to the NCIRT for review and
comment prior to the initial 30% release for the site (see credit release section below). The baseline
report will be performed by the firm awarded the monitoring contract and provided by NCDMS
together along with the designer -sealed record drawings. The most recent DMS As -Built Baseline
Monitoring Report Template will be used to document the baseline conditions. Annual monitoring data
will be reported using the latest NCDMS Monitoring Report Template. All monitoring reports will
include at least a brief narrative of site developments, a representative photo log, and a Current
Condition Plan View (CCPV).
Monitoring Year 1 will be calendar year 2020. The proposed locations of monitoring features are
shown in the monitoring figure below as an Attachment. Annual monitoring reports will be completed
for all seven years and provided to the NCIRT no later than April 1 of each monitoring year. Monitoring
data collected on the site will include reference photos, plant survival analyses, hydrology, channel
stability analyses, and visual assessments.
Stream monitoring will include monitoring of the hydrologic and geomorphic functions of the project
restoration reaches. Vegetation monitoring will evaluate the establishment of planted and volunteer
vegetation across the site. A visual assessment of the entire project will be conducted on an annual
basis. This data will be presented in the Current Condition Plan View (CCPV) with supporting

*In addition, should bank erosion develop in excess of 5% of the reach length, or at the discretion of NCDMS, bank pins
sufficient to capture the observed variation in erosional features will be installed. Pins will be 3 foot sections of 3/8" rebar driven
at the bank toe and above at approximately 2 foot intervals. Each vertical array will be captured with a GPS and included on the
CCPV. Pins should be measured for bank retreat at a minimum of twice per year. Pin installation and monitoring would follow
the October 24, 2016 USACE Public Notice guidance.

4. Proposed Credit Release Schedule
The project will follow the release schedule specified in the October 2016 NCIRT guidance for
ILF/NCDMS projects. The following conditions will apply to the credit release schedules:
A. A reserve of 10% of a site's total stream credits will be released after four bankfull events have
occurred, in separate years, provided the channel is stable and all other performance standards are
met. In the event that less than four bankfull events occur during the monitoring period, release
of these reserve credits is at the discretion of the NCIRT.
B. After the second milestone, the credit releases are scheduled to occur on an annual basis,
assuming that the annual monitoring report has been provided to the USACE in accordance with
Section IV (General Monitoring Requirements) of this document, and that the monitoring report
demonstrates that interim performance standards are being met and that no other concerns have
been identified on-site during the visual monitoring. All credit releases require written approval
from the USACE.
C. The credits associated with the final credit release milestone will be released only upon a
determination by the USACE, in consultation with the NCIRT, of functional success as defined in
the Mitigation Plan.
