1.0. INTRODUCTION
Crescent Resources, Inc. received a US Army Corps of Engineers (USACE) Nationwide
Permit No. 13 (Action ID SAW-2008-01107-359) on April 10, 2008 and a NC Division
of Water Quality (NCDWQ) (Project No. 04-0241) 401 Water Quality Certification on
April 14, 2008 authorizing the removal of 35 feet of culvert with subsequent bank
stabilization. This report represents the as-built conditions of the site following the
construction and planting and will be used for comparison with monitoring data gathered
annually for the next three years.
2.0 PROJECT BACKGROUND
The Old Wildlife Club removed one culvert on-site and restored stream beds and banks
within the culvert removal area. The removal/stabilization activity daylighted
approximately 35 linear feet of stream. Restoration of the culvert site involved the
removal of the culvert structures and adjacent road embankments and excavation of a
new channel that connects the upstream and downstream reaches.
The culvert and road embankment were removed and the new banks seeded, matted and
planted with native vegetation. The cross-sectional area and slope for the new channel
section were matched to the area and slope of stable adjacent sections. One step-pool
structure was utilized to establish grade control and protect new banks.
2.1 Project Location
The project site is on an unnamed tributary of Lake James in McDowell County, North
Carolina and is located in the Catawba River Basin, the NCDWQ sub-basin 03-08-30,
and the US Geological Survey (USGS) 03050101 unit. It is located approximately 1.0
mile north of the town of Nebo, NC. The latitude and longitude for the project area is
35.7384102°N and 81.9302687°W. From Asheville, take Interstate-40 east towards
Statesville. Take Exit 90 towards Nebo and turn right onto Harmony Grove Road. Turn
left onto US Highway 70. Turn right onto NC Highway 126. Turn left onto Wildlife
Road where the site will be located on the right. A site location map and a USGS
topographic map are attached as Figures 1 and 2.
2.2 Project Goals and Objectives
The objectives of the project were to:
1. Remove an existing culvert
2. Re-connect aquatic habitats;
3. Establish native vegetation through a forested riparian buffer; and
4. Improve the natural aesthetics of the stream corridor.
The culvert removal and stream restoration involved the following steps:
3
1. Remove culvert and excavate new channel through road embankment with
disposal of roadbed gravel (if any) outside the limits of the restoration area;
2. Construct grade control structures;
3. Apply temporary seed and erosion control matting to the banks; and,
4. Plant native herbaceous and woody vegetation on the banks and at the top of
both banks to establish a vegetative buffer.
2.3 Restoration Approach
Design:
The project approach involved some site-specific design during construction. The culvert
and road embankment were to be removed, a new channel section excavated including
the placement of a log toe, and the new banks seeded, matted and planted with native
vegetation. The cross-sectional area for the new channel section was matched to the
cross-sectional area of an adjacent section. Slope was to be controlled with a step
structure to establish grade control and protect new banks within the culvert removal
areas. Drawings of the project design are attached.
Due to the small size of the stream channel and the existing topography and vegetative
conditions, the most appropriate bank stabilization and planting methods were chosen.
Erosion control matting, seeding, live staking, and containerized tree and shrub planting
were all designed for both rapid and long-term bank stabilization and vegetation survival.
Implementation:
Construction of the new stream channel subsequent to culvert removal was performed in
June 2008. Erosion control matting was placed to the top of bank. Outside of the erosion
control matting, riparian trees and shrubs were planted on 10 to 12-foot centers in
accordance with the NC Ecosystem Enhancement Program's "Guidelines for Riparian
Buffer Restoration". Based on a project area of 0.05 acres and a target density of 320
trees per acre, the required number of plantings for the site is 16 trees and/or shrubs.
As-built Survey:
Personnel from Clearwater Environmental Consultants, Inc. performed an as-built survey
of the restoration sites in July 2008. One cross-section and a longitudinal profile were
measured using a Nikon total station. Due to the small size of the restoration reach and
upland buffers, all planted trees were counted.

3.0 MONITORING
Environmental components monitored in this project are those that allow an evaluation of
channel stability and riparian survivability. Specifically, the success of channel
modification, seeding, and woody vegetation plantings will be evaluated for three (3)
years.
3.1 Vegetation Monitoring
Survival of planted vegetation will be evaluated using survival counts and all rooted
vegetation will be flagged and evaluated for at least 3 years to determine survival. The
complete planted buffer will be assessed due to the small areas planted. Success will be
defined as a density of 320 trees/acre after three years or greater tree-shrub density due to
the establishment of native volunteer species. Based on a project area of 0.05 acres and a
target density of 320 trees per acre, the required number of plantings for the site is 16
trees and/or shrubs. Table 3 contains information regarding the species composition of
plantings.

TOTAL 52 100.0%
3.2 Stream Monitoring
Cross-sections: One permanent cross-section was established. The cross-section was
marked on both banks with permanent pins to establish the exact transect used. The
annual cross-section survey will include points measured at breaks in slope and any
identifiable features (bankfull, inner berm, etc.).
Success Criteria: There should be little or no change in the as-built cross-section. If
changes in the cross-section occur, then they should be evaluated to determine if they
represent a movement toward a more unstable condition (down-cutting, erosion) or are
minor changes that represent an increase in stability (settling, vegetative changes,
deposition along the banks, decrease in width/depth ratio).
Longitudinal Profiles: A longitudinal profile will be completed annually for a total of
three (3) years. Survey points will include thalweg, water surface, inner berm, bankfull,
and top of low bank where they are identifiable. Each of these points will be taken at the
head of each feature, e.g. riffle, run, pool, and glide where possible, and the max pool
depth. Water surface will be used to calculate slope for the project reach.
As-built restoration reach slope: 0.041 ft/ft
Success Criteria: The as-built longitudinal profile should show that the bedform features
are remaining stable, e.g. they are not aggrading or degrading. The pools should remain
deep with flat water surface slopes and the steps/riffles should remain steeper and
shallower.
6
Photo Reference Sites: Photographs used to evaluate restored sites will be made with a
digital camera. There are 4 photo reference sites showing each bank and the stream
channel. Reference sites will be photographed once per year for at least 3 years
following construction.
Longitudinal reference photos: The stream will be photographed longitudinally at the
upstream end of the restoration site looking downstream and at the downstream end of
the site looking upstream.
Lateral reference photos: Photographs will be taken of both banks at the cross-section.
The water's edge or channel's edge will be located in the lower edge of the frame and as
much of the bank as possible included in each photo.
Success Criteria: Photographs will be used to subjectively evaluate channel aggradation
or degradation, bank erosion, success of riparian vegetation and effectiveness of erosion
control measures. Longitudinal photos should indicate the absences of developing bars
within the channel or an excessive increase in channel depth. Lateral photos should not
indicate excessive erosion or continuing degradation of the bank over time. A series of
photos over time should indicate successional maturation of riparian vegetation.
Vegetative succession should include initial herbaceous growth, followed by increasing
densities of woody vegetation and then ultimately a mature overstory with herbaceous
understory.

4.0 CONCLUSIONS AND RECOMMENDATIONS
Crescent Resources, Inc. received a USACE Nationwide Permit No. 13 and a NCDWQ
Water Quality Certification in April 2008 authorizing the removal of 35 feet of culvert
with subsequent bank stabilization. The culvert was removed and the banks stabilized
and planted in June 2008. An as-built survey of post construction conditions was
performed in July 2008. The as-built survey will be used to access the stability of the
project in the future.
4.1 Vegetation Monitoring
At the time of the as-built, all planted trees and shrubs had survived. However,
herbaceous species growth has been slow due to lower-than-average rainfall conditions.
7
The first year of monitoring of vegetation will take place in 2009 and continue for a total
of three (3) years.
4.2 Stream Monitoring
The daylighted stream reach appears to stable in cross-section and profile. The rock vane
appears to be functioning. Post-construction sediment in the channel should be removed
during normal sediment transport functions. Aquatic habitat is expected to improve as
the reach continues to stabilize and the buffer matures.
