EXECUTIVE SUMMARY
Restoration Systems, L.L.C. has completed restoration of streams and wetlands at the Three Mile Creek
Restoration Site (hereafter referred to as the "Site ") to assist the North Carolina Ecosystem Enhancement
Program in fulfilling stream and wetland mitigation goals. The Site, located in southwestern Avery
County approximately 5.2 miles northeast of Spruce Pine, North Carolina, provides 8103 stream
mitigation units and 3.7 riparian wetland mitigation units as described in the As -Built Mitigation Plan
dated April 2009. The Site is located in United States Geological Survey (USGS) Hydrologic Unit and
Targeted Local Watershed 06010108010020 (North Carolina Division of Water Quality Subbasin 04 -03-
06) of the French Broad River Basin. This report serves as the Year 1 (2009) annual monitoring report.
Primary activities at the Site included l) stream restoration, 2) stream enhancement, 3) stream
preservation, 4) wetland restoration and enhancement, 5) soil scarification, and 6) plant community
restoration. Project restoration efforts provide 8103 Stream Mitigation Units and 3.7 riverine Wetland
Mitigation Units.
Eight vegetation plots (10 meters by 10 meters in size) were established and permanently monumented.
These plots were surveyed in September 2009 for the Year 1 (2009) monitoring season. Vegetation
sampling across the Site was above the required average density with 708 planted stems per acre
surviving. In addition, each individual plot was above success criteria.
Eleven cross - sections and 3000 linear feet of longitudinal profiles were measured for the Year 1 (2009)
monitoring. As a whole, monitoring measurements indicate that there have been minimal changes in both
the longitudinal profile and cross - sections as compared to as -built data. The as -built channel geometry
compares favorably with the emulated, stable E/C type stream reach as set forth in the detailed mitigation
plan and construction plans. Current monitoring has demonstrated dimension, pattern, and profile were
stable over the course of the monitoring period. No stream problem areas were noted within the Site
during the Year 1 (2009) monitoring year.
All three of the monitored gauges within restoration areas were inundated/saturated within 12 inches of
the surface for greater than 12.5 percent of the growing season, which extends from May 1 to October 11
(163 days).
In summary, Site vegetation, streams, and wetland hydrology met success criteria for Year 1 (2009)
monitoring.

Threemile Stream and Wetland Restoration Site

1.0 PROJECT BACKGROUND
1.1 Location and Setting
Restoration Systems, L.L.C. (Restoration Systems) has completed restoration of streams and wetlands at
the Three Mile Creek Restoration Site (hereafter referred to as the "Site ") to assist the North Carolina
Ecosystem Enhancement Program (NCEEP) in fulfilling stream and wetland mitigation goals. The Site,
The Site, located in southwestern Avery County approximately 5.2 miles northeast of Spruce Pine, North
Carolina, provides 8103 stream mitigation units and 3.7 riparian wetland mitigation units as described in
the April 2009 As -Built Mitigation Plan(Figures 1 and 2, Appendix A). The Site is located in United States
Geological Survey (USGS) Hydrologic Unit and Targeted Local Watershed 06010108010020 (North
Carolina Division of Water Quality Subbasin 04- 03 -06) of the French Broad River Basin.
Directions to the Site:
➢ From Asheville or Raleigh, take I -40 to Marion; take NC 226 north through Linville Falls; go left
on NC 194; site is —4.5 miles on left
➢ Or, From Asheville take 19/23 North to 19E through Spruce Pine to NC 194
➢ Take a right on NC 194 and travel approximately l .5 miles
➢ The Site is on the right
➢ Latitude, Longitude of Site: 35.9827 °N, 81.9843 °W (NAD83 /WGS84)
1.2 Project Objectives
The primary components of the restoration project included 1) construction of a stable, riffle -pool stream
channel; 2) enhancement of water quality functions within and downstream of the Site; 3) creation of a
natural vegetated buffer along restored stream channels; 4) restoration of jurisdictional riverine wetlands in
the Site; 5) improvement of aquatic habitat and species diversity by enhancing stream bed variability; and
6) restoration of wildlife functions associated with a riparian corridor /stable stream.
1.3 Project Structure, Restoration Type, and Approach
An approximately 26.68 -acre conservation easement was placed on the Site to incorporate all restoration
activities. The Site contains 4.8 acres of hydric soil, Three Mile Creek, 12 unnamed tributaries (UTs) to
Three Mile Creek, Fork Creek, and adjacent floodplains, which represent the primary hydrologic features
of the Site. Prior to construction, the project was characterized by agricultural land utilized for Christmas
-- tree and ornamental landscape nursery plant production, timber harvest, and livestock grazing. Agricultural
practices included the maintenance and removal of riparian vegetation and relocation, dredging, and
straightening of onsite streams. In addition, hydric soils were disturbed due to regular plowing and
vegetation maintenance, hoof shear from livestock, and the removal of groundwater hydrology inputs from
the rerouting and straightening of Site tributaries.
Restoration of Site streams and wetlands will result in positive benefits for water quality and biological
diversity in the Three Mile Creek watershed. Targeted mitigation efforts at the Site were accomplished by:
Removing nonpoint and point sources of pollution associated with agricultural practices including
a) cessation of broadcasting fertilizer, pesticides, and other agricultural chemicals into and adjacent
to the Site and b) provide a forested riparian buffer to treat surface runoff.
Reducing sedimentation within onsite and downstream receiving waters by a) reducing bank
erosion associated with vegetation maintenance and plowing adjacent to Site streams and wetlands
and b) planting a forested riparian buffer adjacent to Site streams and wetlands.
Reestablishing stream stability and the capacity to transport watershed flows and sediment loads by
restoring a stable dimension, pattern, and profile supported by natural in- stream habitat and
grade /bank stabilization structures.
Annual Monitoring Report page 1
Threemile Stream and Wetland Restoration Site

4. Promoting floodwater attenuation by a) reconnecting bankfull stream flows to the abandoned
floodplain terrace; b) restoring secondary, dredged, straightened, and entrenched tributaries,
thereby reducing floodwater velocities within smaller catchment basins; c) restoration of
depressional floodplain wetlands and floodwater storage capacity within the Site, and d)
revegetating Site floodplains to increase frictional resistance on floodwaters.
5. Improving aquatic habitat with bed variability and the use of in- stream structures upstream of a
reach identified by the North Carolina Wildlife Resources Commission as supporting naturally
reproducing rainbow trout populations.
6. Providing a terrestrial wildlife corridor and refuge in an area that is developed for agricultural
production.
As constructed, the Site restored historic stream and wetland functions, which existed onsite prior to
channel straightening and dredging, agricultural impacts, and vegetation removal. Stream construction of
meandering, E/C stream channel resulted in 6057 linear feet of stream restoration, 618 linear feet of stream
enhancement (Level I), 875 linear feet of stream enhancement (Level II), 6421 linear feet of stream
preservation, 2.5 acres of riverine wetland restoration, and 2.3 acres of riverine wetland enhancement
(Table 1).

1.5 Monitoring Plan View
Monitoring activities for the Site, including relevant structures and utilities, project features, specific
project structures, and monitoring features are detailed in the monitoring plan view in Figure 2 of
Appendix A. Site features including vegetation, stream dimension (cross- sections), stream profile and
pattern, wetland hydrology, and photographic documentation were monitored in Year 1 (2009).
2.0 PROJECT CONDITION AND MONITORING RESULTS
2.1 Vegetation Assessment
Following Site construction, eight plots (10 meters by 10 meters in size) were established and monumented
with metal fence posts at all plot corners and PVC at each plot origin. Sampling was conducted as outlined
in the CVS -EEP Protocol for Recording Vegetation, Version 4.0 (Lee et al. 2006)
( http: / /cvs.bio.unc.edu /methods.htm); results are included in Appendix B. The taxonomic standard for
vegetation used for this document was Flora of the Carolinas, Virginia, Georgia, and Surrounding Areas
(Weakley 2007). The locations of vegetation monitoring plots were placed to accurately represent the
entire Site and are depicted on the monitoring plan view in AppendixA.
2.1.1 Vegetation Success Criteria
Success criteria have been established to verify that the vegetation component supports community
elements necessary for forest development. Success criteria are dependent upon density and growth of
"Characteristic Tree Species." Characteristic Tree Species include planted species, species identified
through inventory of a reference (relatively undisturbed) forest community used to orient the planting plan,
and appropriate Schafale and Weakley (1990) community descriptions. All species planted and identified
in the reference forest will be utilized to define "Characteristic Tree Species" as termed in the success
criteria (Table 5).

Threemile Stream and Wetland Restoration Site

An average density of 320 stems per acre of Characteristic Tree Species must be surviving at the end of the
third monitoring year. Subsequently, 290 Characteristic Tree Species per acre must be surviving at the end
of year 4 and 260 Characteristic Tree Species per acre at the end of year 5.
If vegetation success criteria are not achieved, based on average density calculations from combined plots
over the entire restoration area, supplemental planting may be performed with tree species approved by
regulatory agencies. Supplemental planting will be performed as needed until achievement of vegetation
success criteria.
2.1.2 Vegetative Problem Areas
No vegetation problem areas were identified within the Site during Year 1 (2009) Monitoring.
2.2 Stream Assessment
Eleven permanent cross - sections were established after construction was completed. Measurements of
each cross - section include points at all breaks in slope including top of bank, bankfull, and thalweg. Riffle
cross - sections are classified using the Rosgen stream classification system. Longitudinal profile
measurements of 3000 linear feet of stream include thalweg, water surface, and bankfull; with each
measurement taken at the head of facets (i.e. riffle, run, pool, and glide) in addition to the maximum pool
depth.
2.2.1 Stream Success Criteria
Success criteria for stream restoration will include 1) successful classification of the reach as a functioning
stream system ( Rosgen 1996) and 2) channel variables indicative of a stable stream system. Annual
monitoring will continue until success criteria are met and no less than two bankfull events have occurred,
as determined by in situ crest gauge, otherwise monitoring will continue until the second bankf ill event has
occurred.
Visual assessment of in- stream structures will be conducted to determine if failure has occurred. Failure of
a structure may be indicated by collapse of the structure, undermining of the structure, abandonment of the
channel around the structure, and/or stream flow beneath the structure.
2.2.2 Bankfull Events
No bankfull events were documented during the Year 1 (2009) monitoring period.

2.2.3 Stream Problem Areas
No stream problem areas were noted within the Site during the Year 1 (2009) monitoring year.
2.2.4 Categorical Stream Feature Visual Stability Assessment
The stream was visually inspected during the Year 1 (2009) monitoring period using eight feature
categories and various metrics within each category. Assessment features included riffles, pools, thalweg,
meanders, channel bed, structures, and root wads /boulders. A table for semi - quantitative assessments of
the stream is included in Appendix C (Table C1). The mean percentage of performance for features is
summarized in the table below.

2.2.5 Quantitative Stream Measurements
During the Year 1 (2009) monitoring period I 1 cross - sections and 3000 linear feet of longitudinal profile
were measured. Permanent cross - sections and longitudinal profiles are included in Appendix C; each is
graphically depicted for as -built through Year 1 (2009) for analysis. As a whole, monitoring measurements
indicate minimal changes in both the longitudinal profile and cross - sections as compared to as -built data.
The channel geometry compares favorably with the emulated, stable E/C type stream reach as set forth in
the detailed mitigation plan and as constructed. Current monitoring has demonstrated dimension, pattern,
and profile were stable over the course of the monitoring period. Table for baseline data and annual
quantitative assessments are included below.
2.3 Wetland Assessment
Three groundwater gauges were installed in wetland restoration and enhancement areas to provide
representative coverage of the Site. One additional gauge was placed in a reference wetland area. Graphs
of groundwater hydrology and precipitation from a nearby rain station (Weather Underground 2009) are
included in Appendix D.
2.3.1 Wetland Success Criteria
Target hydrological characteristics include saturation or inundation for 5 to 12.5 percent of the growing
season, during average climatic conditions. During growing seasons with atypical climatic conditions,
groundwater gauges in reference wetlands may dictate threshold hydrology success criteria (75 percent of
reference). These areas are expected to support hydrophytic vegetation. If wetland parameters are
marginal as indicated by vegetation and/or hydrology monitoring, a jurisdictional determination will be
performed.
2.3.2 Wetland Problem Areas
No wetland problem areas were identified within the Site during Year 1 (2009) monitoring.
