Harmon Dairy Stream Mitigation Project 2020 Corrective Action Plan
This corrective action plan developed by Clearwater Environmental Consultants Inc. (CEC)
includes the scope and timeline for remaining work necessary to meet the construction phase
requirements for Harmon Dairy Stream Mitigation Project (Site). The project area is located off
of NC Highway 9 in the town of Green Creek (Figures 1 and 2). The main components of the
plan include: (1) modification of fence lines, (2) signage installed to the Conservation Easement
boundary (3) a supplemental planting plan for low stem density areas (4) invasive plant treatment
and (5) revision to the Conservation Easement (CE) Boundary due to revised placement of
stream crossing on UT3.

1.0 Modification of Fence Lines
The As-Built Report for the Site includes sealed record drawings produced by Ben Patton Land
Surveying, PLLC. The drawings indicate the locations of conservation easement boundaries and
installed fence lines. Figure 3 indicates locations where the installed fence line protrudes inside
the conservation easement boundary, thereby violating the restrictions of the conservation
easement.
Corrective action includes moving the fence line to outside the conservation easement
boundary. This will be performed by a licensed contractor and professional land surveyor.
The timeline for completion of the modification of the fence line is December 2020.

2.0 Signage installed to the conservation easement boundary
Guidance set forth by the North Carolina Interagency Review Team’s (NCIRT) “Wilmington
District Stream and Wetland Compensatory Mitigation Update” – October 24, 2016 (USACE
2016) indicates that the final as-built survey include verification of the installation of
conservation easement boundary markers. The easement boundary markers were not installed as
described in the construction specifications.
Corrective action includes installing signage at all conservation easement corners and
along boundary lines at 100’ intervals as described per the technical specifications for as-
built survey produced by Wildlands Engineering, Inc. on March 9, 2018. Modification to
the placement of wooden posts, fence lines and metal t-posts (described above in Section
1.0) will occur prior to the placement of signage. The non-fenced areas of the easement
will require a stakeout survey, to be performed by a professional land surveyor to locate
and monument easement corners and boundaries. Signage will be placed on existing
installed wooden witness posts/fence posts and t-posts with additional posts added as
necessary in the non-fenced areas of the easement as described below. The timeline for
completion of the installation of signage is December 2020.

Technical specification for As-Built survey. Wildlands Engineering 2018:

Contractor agrees to install wooden witness posts and signage at all conservation
easement corners as follows:

 Treated wood post; 6” round, 8’ long
 Treated to a minimum of 0.4 PCF
 All posts shall be installed 2’‐3’ below ground (wider end set in the ground)
 Place post within 6” of the conservation easement corner
 Attach conservation easement signs (to be provided by Owner) with rust resistant
bolts, nails or screws, 4 per post
 Each sign shall be placed parallel to the conservation easement boundary line,
facing away from the conservation area with the corners wrapped around the post
and secured
 Upper 6” of each post shall be coated with a water based tree marking paint
(Nelson tree marking paint 6‐8 year or similar) including post top; signage shall
be installed just beneath yellow paint
 Each post shall be installed plumb and set solidly in the ground to prevent future
movement
 Contractor agrees to use cement if needed to add stability as follows: 40‐80 lb
bag of cement per post; use for unconsolidated and sandy soils where necessary
to add stability and prevent future movement; all posts must be stable, complete
and approved by Engineer

Contractor agrees to install metal witness posts and signage along all conservation
easement boundary lines (i.e., between corners) as follows:

 In non‐wooded areas set 6‐foot T‐Post (tops painted yellow) at no more than 100’
intervals along boundary lines
 In wooded areas where trees on the subject property can be marked, blaze and
mark conservation easement lines. Conservation easement lines shall be marked
with conservation easement signs (to be provided by Owner) and blazed with
yellow paint (Nelson tree marking paint 6‐8 year or similar).

3.0 Supplemental Planting Plan for low stem density areas
Bare root planting stock was installed on site during April of 2019. The baseline vegetation
monitoring for the site was performed in July 2019. The total overall planted density
representative for the site was 563 stems/acre, which exceeds the interim measure of vegetative
success of at least 320 planted stems per acre at the end of the third monitoring year. However,
Permanent vegetation monitoring plots (PVP) 1, 4, 5 and 6 do not individually meet the interim
vegetative success criteria. In addition, Temporary vegetation monitoring plot (TVP) 5 did not
meet stem density criteria. Stem density and survivability was observed low in the vicinity of
these vegetation monitoring plots. Figure 3 shows the location of vegetation monitoring plots,
and recommended areas for supplemental planting. These planting areas are approximate and
may be modified following the MY1 vegetation monitoring.
Corrective action includes installation of supplemental bare root stock in four areas
indicated on Figure 3 shown to have low survivability of planted bare root stems. The
proposed supplemental planting areas have a combined area of 1.4 acres. Supplemental
planting will include species listed on the Baker Grading and Landscaping Plant and Seed
Material memo dated April 3, 2019 (Attachment A), installed on 10 x 10 spacing, or
approximately 455 trees. The timeline for completion of the installation of supplemental
planting is March 2021

4.0 Invasive Plant Treatment
Approximate invasive plant treatment areas are shown on Figure 3. Invasive plants observed on
site include kudzu, cocklebur, Chinese privet, Chinaberry and tree of heaven. Only mechanical
removal of invasive species such as kudzu and Chinese privet have been completed during the
As-built.

Corrective action includes chemical treatment of invasive exotic plants with herbicide
following recommended procedures for herbicide application at aquatic sites within
conservation areas. The work will be supervised by Tryon Equestrian Partners (TEP)
staff with a certified herbicide applicators license, as well as CEC staff biologists. The
timeline for completion of the herbicide application is September 2020.

5.0 Revision to Conservation Easement Boundary
A Conservation Easement (CE) on the property is held by the Polk County Soil and Water
Conservation District (SWCD) to permanently protect the improved aquatic habitats and riparian
buffers and restrict future activities that might otherwise compromise the functions and services
of the aquatic resources (Attachment B). The permanent conservation easement recorded January
23, 2017 extends at least 50 feet beyond the top of both banks on all UTs. Within the conservation
easement, the riparian buffers are planted with native trees and shrubs in order to provide post-
construction bank stability, erosion control and riparian habitat enhancement. The ford crossing
on UT3 was modified during construction to avoid unnecessary tree removal. The extended gravel
road for the UT3 crossing extending to the southwest penetrates the boundary of the conservation
easement by approximately 30 feet.

Corrective action: If the crossing is to be maintained in this location, a modification to the
2017 conservation easement boundary held by SWCD will be necessary. All site protection
instruments require 60-day advance notification to the US Army Corps of Engineers
(Corps) and the NC Division of Water Resources (DWR) prior to any action to void,
amend, or modify the document. No such action would take place unless approved by the
Corps and DWR. The revised boundary would be surveyed and marked by a professional
land surveyor. The timeline for completion of the CE boundary revision is December 2020.
