DMS Project # 276 Baseline Monitoring Report Addendum

1.0 Executive Summary
1.1 Site Description
The North Carolina Division of Mitigation Services (DMS) restored approximately 2,919
linear feet of stream on Richland Creek, which flows through the Paschal Golf Course in
Wake Forest, North Carolina. The site was originally constructed in mid -2010, with
original baseline monitoring conducted that same year. Since that time, multiple problem
areas were tracked over the course of monitoring. A maintenance design was completed
in 2015 and maintenance construction was completed in March 2016. This report details
the results of that maintenance.
1.2 Adaptive Management Needs
Since construction, the majority of the stream channel has remained stable, but there has
been significant bank erosion and structural failure in six select locations. The large
amount of erosion has resulted in vertical banks and loss of most vegetative protection. In
some areas failed structures caused a realignment of the thalweg towards these vertical
and actively eroding banks.
The six repair areas identified in 2015 were designated as Areas 1-6. The pre -
construction conditions and the corrective repairs are described below.
1.3 Repair Goals and Objectives
The project accomplished the goals of this repair by implementing the objectives as
described below.
Goals:
• Stabilize six actively eroding portions of Richland Creek on the project site.
Objectives:
• Build stable banks along the eroded sections of Richland Creek using vegetated
soil lifts.
• Realign the thalweg to the channel center to alleviate near bank stress where
necessary.
1.4 Additional Project Information
Summary information/data related to the repair design approach and conceptual plan,
including a narrative background and supporting information, can be found in the
conceptual repair plan, and preceding project information can be found in the original
mitigation and restoration plan documents available on the DMS website.
2.0 Repair Approach
2.1 Description
In October 2014, KCI conducted a site survey and assessment at the Paschal Golf Course
(Richland Creek) Site. This assessment collected detailed visual and topographic
information at six actively eroding areas. The information from this survey and
assessment was used to develop a Conceptual Repair Plan (December 2014) and final
construction plans (April 2015) to correct the actively eroding, unstable parts of the
Paschal Golf Course (Richland Creek)

channel. The repairs began in late -February 2016 and were completed by late -March
2016.
2.1.1 Stream Repairs
Area 1 consisted of an actively eroding outer bank. The bank had eroded through
the bench and was eroding the terrace. Additionally, a mid -channel bar had
formed in this location, which split the flow and caused additional erosion along
the right bank of the downstream riffle. This was fixed by building vegetated soil
lifts on a stone foundation along the outer bank, grading the inner bank back, and
developing a new pool. The bank was built out towards the channel, but not as
far as the original bank. This structure was tied to a downstream constructed
riffle with adjacent soil lifts.
Area 2 also focused on an eroding outer bank. Unlike Repair Area 1, the erosion
had not cut back to the terrace and there were no problems with deposition in this
area. A vegetated soil lift with a stone foundation was installed in this location.
Area 3 consisted of an eroding outer bank, similar to Repair Area 2. The erosion
stopped at a boulder single vane structure. Similar to the other repairs a vegetated
soil lift with a stone foundation was installed in this location. The stones in the
vane structure were removed up to where the vane tied into the bank, which was
incorporated into the foundation for the lifts.
Additionally, Repair Area 3 has a side drain that comes from a small stormwater
culvert just downstream of the bank to be repaired. This drain, which alternates
between filling with sand and then washing back out, was stabilized with riprap
at the confluence with the channel.
The most minor repair area was Repair Area 4, which consisted of an actively
eroding outer bank. Similar to Repair Area 3, there is a boulder structure at the
downstream end of the erosion that halted any further erosion. This structure has
a better angle and was left in place. A vegetated soil lift with a stone foundation
was installed in this location.
Area 5 consisted of an actively eroding outer bank downstream of the golf cart
bridge. A 4" PVC drain pipe had been exposed and was hanging from this bank.
A non-functioning single boulder vane was also located in the middle of this
bank. A vegetated soil lift with a stone foundation was installed in this location.
The PVC pipe is connected to an active drain line and was incorporated into the
soil lifts. The vane arm was removed and the boulders were reused in the
foundation.
Area 6 was in the same state as Repair Area 3, with an eroding outer bank and
non-functioning boulder vane. The repair approach was the same.
For site photos and repair locations depicted in the record drawings and
contractor's as -built, see Appendices A, B, and C, respectively.

2.1.2 Vegetated Soil Lifts
Vegetated soil lifts were used throughout the repair to stabilize eroding banks.
These were installed as designed, with a stone foundation that extends 0.2-0.5'
above the water line, approximately three one -foot lifts, and live whips installed
above the stone base and between the lifts. The species utilized for the whips
were harvested onsite and include black willows (Salix nigra), silky willows
(Salix sericea), and silky dogwoods (Cornus amomum).
2.1.3 Transplants
There were few viable native trees and shrubs to transplant in the disturbance
area. Most of the trees were pine. Only three trees were transplanted during
construction.
2.1.4 Additional Planting
Additional planting of containerized native trees and shrubs was conducted
throughout the easement where there was disturbance from construction at a
minimum density of 320 stems/acre. A total of 270 trees and shrubs were
planted. Trees were planted outside of the utility easement and play over areas
and included equal numbers of river birch (Betula nigra), sycamore (Platanus
occidentalis), and willow oak (Quercus phellos). Shrubs were planted within the
utility easement and play over areas and included equal numbers of silky
dogwood (Cornus amomum), spice bush (Lindera benzoin), and buttonbush
(Cephalanthus occidentalis).
All disturbed areas were seeded with permanent seeding as specified in the repair
design plans.
2.1.5 Contractor Warranties
The contractor is responsible for maintaining a survival density of 320 stems/acre
on all areas cleared and planted for the duration of the first growing season
following installation. The contractor will incur the cost of replacement through
this period. At least thirty days prior to the end of the first growing season an
on-site inspection will be conducted and the Contractor will be directed
accordingly on mortality and replacement requirements, if necessary.
The contractor also guarantees materials and workmanship against patent defects
arising from faulty materials, faulty workmanship or negligence for a period of
twelve months following the final acceptance of the work. The contractor will
replace any defective materials or workmanship without cost to the owner.
2.2 Restoration Components
The repairs restored the planform of the prior -restored stream and have not caused any
changes to the site's mitigation assets. See Table 1 for the current credit calculation.
