Mt. Pleasant Creek Restoration Project-Bowman Property MY3
PROJECT SUMMARY
Project work at the Mt. Pleasant Creek Restoration Project, Bowman Property (“Bowman”) was completed
in February 2017, and included construction, planting, invasive treatment, and fence installation. Through
this project work, a total of 1,866 linear feet of stream were enhanced or preserved, and 358,604 sf of buffer
were protected, enhanced, or restored. The project stream is perennial and drains a 5.2-acre watershed in
the Cape Fear River Basin (03030003 8-digit cataloging unit) of Randolph County, North Carolina. The Bowman
site has a history of unrestricted livestock access, leading to bank erosion, compaction, and discontinuity
between the stream and its associated floodplain. The completed project will reduce sediment inputs from
failing banks, reduce nutrients and bacteria entering the stream from livestock and will enhance the forested
corridor along the stream floodplain.
The project is protected by a 9.61-acre permanent conservation easement, held by the NC Department of
Transportation. Bowman is located off Whites Chapel Road, approximately 5 miles southwest of Liberty,
North Carolina. The project site is bounded by interspersed pastureland and forested land to the east, forest
to the south, pasture and forest to the north, and agricultural land and forest to the west. Bowman is within
a parent parcel involved with agricultural production for cattle, chicken houses, goats, and hay pasture.
GOALS & OBJECTIVES
The 2009 Cape Fear River Basin RBRP identified HUC 03030003020010 (Sandy Creek) as a Targeted Local
Watershed, of which the project site is a part (NCEEP 2009). The project goals are in line with the following
basin priorities:
- Reduce sources of sediment and nutrients by enhancing riparian buffer vegetation, excluding
livestock, and enhancing stream and buffer function.
The goals for the project are to:
- Restore long term stability to exposed banks and reduce susceptibility to scour.
- Eliminate stream bacteria and nutrient exposure from animal waste and wallow.
- Restore a contiguous riparian buffer that connects to the surrounding forested mature buffer.
The project goals will be addressed through the following objectives:
- Conduct Enhancement I level stream restoration on 530 linear feet of stream by repairing
actively eroding banks and re-establishing the stream pattern where there has been excessive
sediment deposition.
- Conduct Enhancement II level stream restoration on 1,046 linear feet of stream
through a permanent conservation easement and removing cattle access.
- Install Preservation on an additional 290 linear feet of stream by putting the stream in a
permanent conservation easement.
- Riparian buffer restoration, enhancement, and preservation throughout the stream corridor.
DESIGN APPROACH & IMPLEMENTATION
To implement these objectives, project work was completed in February 2017 per the Mitigation Plan. The
as-built and baseline surveys found that the stream was constructed as designed and all structures were
installed as planned. Stream work included installation of 7 soil lifts fortified with live willow whips, a ford
crossing, and constructed riffle in the Enhancement I credit area. Bio-engineering with live staking,
temporary and permanent seeding occurred along all exposed banks, and sloped banks; and transplants
were installed where possible. Invasive treatment occurred throughout the entire easement, using a stump
herbicide treatment method. The site was constructed as designed. The only modification during
construction was the extension of the stone on both sides of the ford crossing.
Mt. Pleasant Creek Restoration Project-Bowman Property 1 MY3
On March 9, 2017, 1.23-acres of riparian buffer was planted per the Mitigation Plan specifications. Five
species of trees were installed at a density of approximately 600 trees per acre. There were two
substitutions from the Mitigation Plan species due to availability and vigor of trees (Nyssa sylvatica and
Quercus nigra). Also in March following planting, 3-strand high tensile electric fencing was installed in the
crossing area.
MONITORING
The monitoring components were installed in March 2017 per the Mitigation Plan monitoring specifications.
Three permanent cross-sections were established at stations 12+12 (XS2), 15+25 (XS3) and 17+00 (XS4). Two
of these cross-sections (12+12 and 17+00) were established at location where previous, pre-construction
cross-sections were installed for comparison. The third cross-section (15+25) was placed across the newly
constructed riffle. A manual cork crest gauge was installed to record the occurrence of bankfull events.
For vegetation monitoring, one permanent and two random 10 m2 vegetation monitoring plots were
established. The location of the planted stems relative to the origin within the permanent plot, as well as
the species in all plots, was recorded by size. Volunteers were recorded by species and size separately from
planted stems. Six permanent photo reference points were established and will be taken annually.
SUCCESS CRITERION
Stream performance standards are based on 2003 Stream Mitigation Guidelines for determination of
channel stability and vegetative success. Stream stability will be documented through 1) annual visual
assessment 2) demonstration of bankfull events, 3) stream photo points and 4) monitoring three cross
sections (for the Enhancement I section only). A minimum of two bankfull events in separate years must
be recorded during the five-year monitoring period to meet success.
Vegetative success criterion is in accordance with North Carolina Division of Water Resources Administrative
Code 15A NCAC 02B.0295 (NCDWR 2014 Temporary Rule). After five years of monitoring, an average density
of 260 woody stems per acre must be surviving and diffuse flow maintained.
MONITORING YEAR 3 RESULTS
Monitoring occurred on June 4 and October 3, 2019. Vegetation monitoring, visual assessments, and cross-
sectional surveys results are summarized in tables below. Although the one permanent plot met success, the
two random vegetation fell below success criteria (Table 5). Walnut volunteers continue to thrive on the
planted areas of the site, as there are many “parent” walnut trees that are large and mast producing. At this
point in the project, the alleopathic properties of the walnut volunteers are becoming evident as they are
dominating the planted areas. Based on the MY3 monitoring, some additional planting is warranted for
dormant season 2019-20. Invasive treatment occurred in spring and fall in 2019 and continues to be on-
going.
There were numerous bankfull events during 2019, at least visually documented twice in the monitoring year
(Table 7). There were several very large trees lifted into the floodplain, evidence of significant rack and debris,
and establishment of some benching. Stream banks area stable. Willow whip live stakes are vigorous and
have established a strong bank foothold.
