' Stream Restoration Plan
Stricker Branch Site
Cabarrus County, North Carolina

Executive Summary
Site Description
The Stricker Branch Stream Restoration Site (Stricker Branch site) is part of HUC 03040105
' and located in the City of Concord and Cabarrus County, NC. The site is located in an
urbanized EEP Targeted Watershed (03040105020040) and consists of a highly unstable,
incised, and straightened stream channel -except for the upper third of the project area,
' which is impounded as water supply source for the former textile mile. The adjacent mill
area has been purchased by developers who intend to create amulti-use commercial and
residential area. The remaining stream on the mill property is a highly altered, degraded, and
entrenched channel with almost no woody vegetation. Below Sign Drive, the stream is
' deeply entrenched/incised and highly unstable with strong visible evidence of actively failing
banks. This area is sparsely wooded and contains invasive species such as Chinese privet.
The project watershed, approximately 1.6 square miles, flows into Irish Buffalo Creek, a
303d listed stream.
Restoration Goals and Approach
The project approach will be to create a stream system that restores ecological function by
providing a physically stable system with habitat features. This will include establishing
appropriate stream dimension, pattern and profile, and providing in-stream features that
imitate bedrock outcrops and provide stability. The project will create stable stream banks
and ariffle/pool system, as well as provide the opportunity to establish root mass that
provides bank stability and habitat from the edge of the water throughout the floodplain. The
project also will seek to reestablish the riparian floodplain corridor with native forest
vegetation and microtopography. Providing the appropriate stream and terrestrial habitat, will
' allow for the ecosystem's lost and impaired functions to be reestablished. The plan also will
incorporate the use of stormwater practices located both outside and inside the conservation
easement, such as level spreaders and detention ponds, to attenuate and treat runoff from the
surrounding developed/developing areas. The stream restoration project/conservation
easement will be surrounded by a larger redevelopment project of the old mill. The stream
buffer design will help control access, but allow for some passive public access/visibility to
' the restored channel.

Charlotte. Next, merge onto US-29 south via Exit 58 toward Monroe/Concord. Turn left onto
McGill Avenue NW and continue until passing Central Drive NW on the right. The project
site is located on the right, after passing Central Drive NW. Please refer to Figure 1 located
in the appendix for a map.
1.2 USGS Hydrologic Unit Code and NCDWQ River Basin Designations
The project site is located in the USGS Hydrologic Unit Code 03040105020040 and the
project stream is located in the Yadkin River Basin and the 03-07-12 sub-basin.
1.3 Project Vicinity Map
Please refer to Figure 1 located in the appendix for a map of the project vicinity.
2.0 Watershed Characterization
2.1 Drainage Area
The project ends at the confluence with Irish Buffalo Creek. The drainage area at this point is
1.65 square miles.
2.2 Surface Water Classification/Water Quality
The project is titled "Stricker Branch," however, the NC Division of Water Quality (DWQ)
refers to the channel as an unnamed tributary (UT) to Irish Buffalo Creek. The NCDWQ
stream index number for Irish Buffalo Creek is 13-17-9-(2). UT to Irish Buffalo Creek has a
' DWQ classification of C. Class C waters are protected for secondary recreation, fishing,
wildlife, fish and aquatic life propagation and survival, and agriculture. Secondary recreation
includes wading, boating, and other uses involving human body contact with water where
such activities take place in an infrequent, unorganized, or incidental manner. There are no
restrictions on watershed development or types of discharges.
2.3 Physiography, Geology, and Soils
The project is located within the Southern Piedmont physiographic province of North
Carolina. It is generally characterized as gently sloping with steeper areas along
drainageways. Elevation within the project area ranges from 610 to 590 feet above sea level.

Cabarrus County, North Carolina
The geology of Cabarrus County consists mostly of igneous rocks such as granite, diorite and
gabbro. Cabarrus County Soil Survey soil mapping of the project area is shown in Figure 3.
Soils within the easement are mapped by the Cabarrus County Natural Resource Conservation
' Service (MRCS) as Chewacla sandy loam. Chewacla soils are a typical hydric floodplain soil
of the North Carolina piedmont and are frequently flooded. Chewacla soils are formed in
loamy alluvial deposits and have a loamy surface layer and subsoil.
2.4 Historical Land Use and Develo ment Trend
p s
' The project site is adjacent to an inactive mill that is being redeveloped. The redevelopment of
this mill is not expected to significantly increase the impervious area on the mill property.
However, due to the growth within the watershed, the amount of impervious area is expected
to increase. The project area is zoned by Cabarrus County as PUD -Planned Unit
Development. This designation provides for the orderly development of land with a mix of
land uses and intensity.
^ The existing land use for the watershed is listed in the table below.
Table 1. Existing Land Cover of the Entire Watershed
2.5 EndangeredlThreatened Species
Federal law under the provisions of Section 7 of the Endangered Species Act (ESA) of 1973,
as amended, requires that any action likely to affect a federally protected species adversely be
subject to review by the U.S. Fish and Wildlife Service. A search of the US Fish and Wildlife
Service website (www.endan~ered.fws.g_ov_) and the North Carolina Natural Heritage Program
website (http://207.4.179.38/n>~/) identified two federally listed species for Cabarrus County.
Each species, its habitat, and status is described in Table 2. The National Heritage Program
database did not indicate any documented occurrences of these species within aone-mile
radius of the project area. Field investigations indicated that the only suitable habitat for
"Schweinitz's sunflower" (Helianthus schweinitzii) within the parcels is mowed frequently
and managed actively. Kimley-Horn staff has been regularly visiting the site since fall of
2004 and has not observed any Schweinitz's sunflowers. Based on these observations, it has
been determined that the project will have no effect on this species.
The species known as "Carolina heelsplitter" (Lasmigona decorate) occurs in six small
streams and one small river in North Carolina, none of which are located in the project
watershed. The status of the Carolina heelsplitter in Cabarrus County is listed as "historic,"
2 ~ IGmley-Han

meaning the species was last observed in Cabarrus County more than 50 years ago. The
downstream third of the project contains shaded stream banks and muddy gravel substrates.
This habitat could meet the requirements for the Carolina heelsplitter; however, the stream is
an urban and degraded stream corridor with very unstable stream banks. No occurrences have
been documented upstream or downstream, so it has been determined that this restoration
project will have no effect on this species. A scoping letter requesting comments from
USFWS was submitted on July 17, 2006. As of this submittal, no reply has been received. A
copy of this letter is included in the CE submittal (Appendix 5).

The state definition for an endangered plant species is "any species or higher taxon of plant whose continued existence as a
viable component of the State's, flora is determined to be in jeopardy" (CS 19B 106: 202.12).
The state definition for an endangered animal species is "any native or once-native species of wild animal whose continued
existence as a viable component of the State's fauna is determined by the Wildlife Resources Commission to be in jeopardy or
any species of wild animal determined to be an 'endangered species' pursuant to the Endangered Species Act" (Article 25 of
Chapter 113 of the Genera! Statutes; 1987).
2.6 Cultural Resources
A project scoping letter was sent to the State Historic Preservation Office (SHPO) on July 17,
2006 to request a review of the project for any potential impacts to cultural resources. A reply
was received dated August 2, 2006 stating SHPO has no comment on the project. A copy of
this letter is included as part of the Categorical Exclusion in Appendix 3.
2.7 Potential Constraints

The conservation easement boundary is shown on the attached Restoration Plans.
2.7.2 Site Access
Sign Drive or the adjacent Mill parking lot (for areas above Sign Drive) will provide
permanent access to the site. During construction, temporary access to the site will be
constructed on either side of Sign Drive to allow access to the upper and lower sections of the
project area.
2.7.3 Utilities
The conservation easement is bordered by a power line easement on the east side and a sewer
easement on the west side. The power line easement does not cross the conservation
easement. The sewer easement crosses the conservation easement in three places as shown in
the attached Restoration Plan and conservation easement. These utility easement areas are
excluded from the conservation easement. The channel in these areas will be enhanced and
stabilized but no mitigation credit will be sought. The contractor is advised to contact North
Carolina One Call prior to beginning any activity and shall follow any OSHA guidelines prior
to working near any power lines.
2.7.4 FEMAIHydrologic Trespass
~ The Federal Emergency Management Association (FEMA) Flood Insurance Rate Map
(FIRM), map number 37025C 0081 D effective November 2, 1994, shows that the project
area is mapped as Zone A. Zone A includes areas within the 100-year flood, base flood
elevations, and flood hazard factors not determined. A No-Rise Certification is being
submitted to The City of Concord/Cabarrus County to prove that the project will not increase
water surface elevations. A copy of the No-Rise Certification will be submitted to EEP under
separate cover once it is received.
3.0 Project Site Streams
The project is composed of one reach that can be divided into three distinct sections for
discussion purposes.
The upper section is an inline pond that that begins at McGill Avenue and ends at the pond
spillway. This pond impounds approximately 750 feet of channel. Historically, the pond was
used to provide water to the old mill. The pond's structure is anon-regulated earthen
impoundment with a concrete spillway (see photos 4 and 5).
The middle section is from the pond spillway to Sign Road. This section is highly entrenched
(bank height ratios greater than 2.5) with highly erosive banks and no connection with its

floodplain (see photo 6). This section contains no woody buffer. This area appears to be in
disequilibrium and has visual signs that it is actively eroding its bed and banks (see photos 9
and 12 ). The channel lacks sinuosity except for one bend just downstream of the spillway
with a radius of curvature that is too tight and lacks the appropriate geometry found in stable
systems .
The lower section is from Sign Road to the confluence with Irish Buffalo Creek. The channel
geomorphology of this section is similar to that of the middle section. The stream is actively
eroding its bed and banks and lacks bed form diversity. The buffer in this section contains
sporadic native hardwoods such as sycamore, sweet gum, box elder, and red maple. The
understory is dominated by invasive species such as privet, Japanese honeysuckle, and
Chinese bent grass. Because the channel has cut down to below rooting depth, the trees
provide very little bank stabilization and as a result are falling into the channel. This section is
also disconnected from its active bank-full floodplain.
3.1 Channel Classification
Kimley-Horn performed a geomorphic survey (cross sections, longitudinal survey, and
pattern) and sampled stream materials (classification and entrainment pebble counts, bar
samples, sub-pavement and pavement samples) on several reaches representative of the
geomorphic settings within the project area. Appendices 10 and 11 show detailed results of
the field assessment. Table 4 below summarizes the channel classifications of the surveyed
reaches within the project area and Restoration Table IV provides detailed morphological
data.
3.2 Channel Discharge
Peak flows were calculated using the North Carolina urban flood-frequency equations for the
Blue Ridge/Piedmont hydrologic region (Robert R. Mason, Fuste et al. 2002) and the North
Carolina Piedmont Rural regional curves (Harman, Jennings et al. 1999). The peak flows
calculated are summarized in the following table.

3.3 Channel Morphology
Restoration Table IV shows a complete channel morphology table showing pattern,
dimension, and profile for all restoration and reference reaches.
3.4 Channel Stability Assessment
Appendix 1 displays photos of existing conditions.
As previously discussed, Stricker Branch has been modified (straightened). Urbanization of
the watershed has increased the frequency of flooding events. Upstream development and
accelerated erosion of upstream unstable banks have contributed excessive fine grain
sediments to the project reaches.
As a result, much of the project reaches have down cut resulting in incised banks and
accelerated bank erosion. With limited access to an "active" flood prone area Stricker Branch
has begun to widen, further accelerating bank erosion. The widened channels receive large
inputs of sand from the upstream bank erosion and this has created sand deposits on the
channel bed with local aggradation in the pools eliminating bedform diversity. Restoration
Table V provides results of a bank erosion assessment for the restoration reach.
Bank height ratios (low bank height divided by the maximum bankfull depth) were
determined for the surveyed reaches. In the methodology used for this report (Rosgen 2001),
bank height ratios between l .l and 1.3 are regarded as "moderately unstable;" ratios between
1.3 and 1.5 as "unstable;" and bank height ratios greater than 1.5 are considered "highly
unstable."
' Table 6 provides a summary of indicators of channel stability and buffer integrity for the
restoration reaches.

3.5 Bankfull Verification
Determination of the bankfull elevation is vital to generating meaningful geomorphic values.
Field indicators for bankfull were strong for the reference reaches; however, due to down
cutting and bed and bank instability, the restoration candidates had weaker bankfull
indicators. To verify bankfull elevations, the bankfull area values for the project reaches and
reference reaches were checked against the North Carolina Piedmont Rural regional curves
(Harman, Jennings et al. 1999). The results indicate a general agreement between the
surveyed site reaches, reference database, and regional curve thus providing a measure of
validation.

Ve etation
3.6 g
Two major areas of land cover were observed within the project area: piedmont alluvial forest
(Schafale and Weakley 1990) and open fields.
The piedmont alluvial forest community borders Stricker Branch along the lower reach and is
situated partially in the floodplain of the Irish Buffalo Creek. The alluvial forest is dominated
by River Birch (Betula nigra), Sycamore (Platanus occidentalis), Black Willow (Salix nigra),
Box Elder (Ater negundo), Black Walnut (Juglans nigra), Sweetgum (Liquidambar
styraciflua), Red Maple (Ater rubrum), Green Ash (Fraxinus pennsylvanica), and Tag Alder
(Alnus serrulata). The understory includes multiple invasives including Chinese Privet
(Ligustrum sinense), Multiflora Rose (Rosa mult~ora), Japanese Honeysuckle (Lonicera
japonica), and Chinese Bentgrass (Microstegium virmineum).
The fields, which border Stricker Branch along the middle reach, are dominated by Fescue
(Festuca spp.) and a variety of other grasses. These areas are maintained by mowing. There is
~' no woody vegetation growing in these areas.
4.0 Reference Stream
4.1 Watershed Characterization
A database of urban and sub-urban piedmont reference streams along with existing site
information and regional curves will be used as an appropriate reference for the site's physical
characteristics and watershed.
4.2 Channel Classification
The collection of stream data that will be is used is classified as a Rosgen stream type "C"
channel. The reference stream morphology is included in Restoration Table 1.

4.5 Vegetation
The reference vegetation was developed using recommended native species. "Recommended
Native Plant Species for Stream Restoration in North Carolina" by Karen Hall of the North
Carolina Stream Restoration Institute was used along with planting plans from previous
projects to develop a species list for each riparian zone.
5.0 Project Site Wetlands

risdictional Wetlands
5.1 Ju
A portion of the site was delineated as open waters by a Kimley-Horn wetland scientist on
July 18, 2006.
Once the pond is drained, it is unknown if isolated pocket wetlands will form in the relic pond
outside the constructed channel The extent of these wetlands is not yet known but is assumed
to be negligible given soil type and known water table. Therefore, no wetland mitigation units
are being sought. Once the pond is drained and stabilized, the bed of the pond and
surrounding areas will be planted with appropriate vegetation.
6.0 Project Site Restoration Plan
The objective of this project is to plan, design, and construct a dynamically stable
stream/riparian corridor to provide an ecological lift for the entire site and watershed. The
restoration plan was designed with consideration of the following site characteristics:
^ Developing/urban watershed
^ Areas of limited belt width due to utility easements
The approach to restoration design is described in the following sections.

6.1 Restoration Project Goals and Objectives
The goal of this project is to restore the site to a naturally functioning stream system designed
to ameliorate the impairment issues typically associated with highly disturbed urban systems.
The project will provide ecological functional lift to the existing system by restoring the
stream and riparian habitat to a stable stream type and vegetative community that is
appropriate for the given valley and watershed conditions. Benefits will include improved
water quality by reducing sediment load through stabilization and reducing nutrient and other
pollutant input through the addition of forested riparian buffers planted with native species.
Additionally the forested buffers and reconnection with an active floodplain bench will
improve channel hydraulics and system capacity. Improvements to the ecosystem included the
a ^~^

addition of in-stream habitat through the use of in-stream structures and bank revetments such
as root wads and log vanes. By providing an appropriate mix of native forest vegetation to
create an appropriate canopy and understory, the soil structure will improve, leaf litter will be
established to support aquatic and terrestrial ecosystems, and shading and cooling will be
provided to improve water quality. This will provide functional uplift for the watershed as a
whole. Anticipated project benefits and the means through which those benefits will be
achieved are outlined below.
Water Quality Goals/Benefits
^ Sediment removal -Eroding stream banks will be stabilized through a Priority I and II
restoration, changing the stream from a sediment source to a stable sediment sink (on the
point bars and floodplain) that neither aggrades nor degrades.
^ Nutrient removal - The addition of native and riparian buffers and reconnection of the
stream to its floodplain in the old pond bed will improve nutrient uptake.
^ Increased dissolved oxygen (DO) levels -
rock vanes, constructed riffles, J-hooks, etc
and DO.
The addition of in-stream structures (including
will increase bed form diversity, turbulence,
^ Reduced thermal pollution - This benefit will be achieved through the restoration and
planting of trees and shrubs in the restored riparian buffer.
^ Stormwater Best Management Practices (BMPs) -Stormwater BMPs will be built on the
east side of the conservation easement just below McGill Avenue to treat Stormwater
runoff from the area. This will also provide local flood storage benefits and treatment of
approximately 11 acres that is approximately 80+% impervious.
Flood Storage Goals/Benelits
Increased flood storage - Priority II restoration on Stricker Branch will connect the
channels to a bankfull bench. Events greater than bankfull (approximate 1.2-year storm
event) will flow onto the new active riparian floodplain.
Habitat Goals/Benefits
Reduced water temperature - This benefit will be achieved through restoration of
canopy trees and buffer as a whole.
^ Improved bed form and habitat diversity - Priority II and Priority III restoration
combined with a geomorphically stable profile supplemented with in-stream structures
will create the proper pool and riffle spacing and depth.

6.4 Stormwater Best Management Practices
6.4.1 Narrative of Site-Specific Stormwater Concerns
The Stricker Branch watershed is in a state of increasing development. As a result, increased
flows from impervious areas are affecting the project site. Therefore, Stormwater BMP's will
be used at appropriate stormwater outfalls to treat stormwater runoff before it reaches the
stream. Currently, the outlets of the existing Stormwater pipes discharge directly into the in-
line pond and/or streams untreated. Many of the areas around these outfalls are erosive.
Adding detention ponds, level spreaders, or outlet protection as shown on the plans will help
alleviate these problems.
6.4.2 Device Description and Application

e
The portion of the existing on-line pond that is outside the conservation easement will be
converted to an off-line stormwater pond. This pond will receive stormwater flow from an
approximately 11-acre sub-watershed that is approximately 80% impervious. The detention
pond will help remove suspended solids from this area.

Stabilized Out
a
All the Stormwater pipes that enter the easement will be stabilized to reduce energy and
erosion at the outfalls. Where appropriate smaller pipes will be treated with a level spreader
and or pre-formed scour hole to both dissipate energy and diffuse/spread runoff over the
created bank full bench and through the planted riparian buffer.
6.5 Natural Plant Community Restoration
A planting plan was developed to restore natural plant communities to riparian areas
throughout the easement area. The planting plan will use recommended native vegetation. The
plan seeks to accelerate the succesional process leading to a mature riparian community. Re-
colonization of cleared riparian habitats characteristically begins with pioneer species that
creates an environment (e.g. shading) suitable for climax species. To initialize the proposed
riparian community, the restoration area will be planted with a mix of pioneer and climax
species that have been selected and arranged to meet the following objectives:
^ Establish mix of shade intolerant canopy and shade tolerant understory species
^ Provide vegetative source of dominant species
^ Establish local seed sources for those species less likely to migrate into the restoration
area
^ Provide stability to disturbed or high stress areas
The design of a planting plan involves several components. The planting zones have been
developed considering site hydrology, soils, and disturbance regimes and are referenced to
stable communities within the same climate zone. Each zone has a unique environment that

dictates species selection and community structure. The planting list reflects which species are
readily available and have a high potential of survival. For a given zone and species, a plant
source and planting type (e.g. containerized or bare root) is recommended. A planting
schedule was developed so that site preparation and plant installation occur at the most
beneficial time and season. After installation, the planting should be verified. The
maintenance plan was developed to assure long-term success of the planting. These planting
plan components are described below.
6.5.1 Planting Zones
The planting plan includes four zones of distinct vegetative composition and structure.
^ Zone 1 -Stream Bank
^ Zone 2 - Riparian/Bankfull Bench
^ Zone 3 -Transitional
^ Zone 4 -Upland
The zones are shown in a typical section in the Restoration Plan and are described below.
Specific species lists are included in the attached planting plans.
j Zone 1 -Stream Bank
The stream channel zone includes the stream channel from base flow to bankfull. The zone
features the steepest slopes (from 3:1 to 7:1) of the zones and highest saturation levels. This
environment dictates the planting of fast-growing, obligate pioneer species, such as black
willows and silky willows, to provide stability to areas at or below bankfull.
Zone 2 -Riparian/Bankfull Bench
The stream bank zone includes the area from the top of bank outward away from the stream to
the toe of slope of the transitional zone. It is an area exposed to regular stream flows and
frequent soil deposition. The most stressed areas are located on the outside bends of
meanders. The banks will be planted with fast-growing, deep-rooted canopy and understory
species, such as silky dogwood, that will provide biostabilization and shading to the stream
Zone 3 -Transitional
The transitional zone extends from the edge of the riparian zone to the upland at a 3:1 slope.
This area will be planted with a mix of canopy and understory species.
Zone 4 -Upland
The upland zone extends from the edge of the transitional zone to the edge of the conservation
easement. This area will provide a transition between the stream restoration project and the
surrounding areas.

6.5.2 Plant Sources
The planting plan utilizes two sources of plants. Nursery stock will be tied directly to the
initial planting and will be utilized in numbers to support permit guidelines. The remaining
source (i.e., recruitment) will be factored into the selection of species in the plant list. The
plant list includes a significant portion of species not likely to establish from natural
propagation.
Nursery Stock
The planting plan may utilize any of the following nursery stock forms of woody species: bare
roots, tublings, live stakes, containerized seedlings, and ball and burlap. Additionally, the
planting plan also may use seeds from commercial sources. For the woody forms of
vegetation, the planting plan prescribes that they are grown locally under environmental
conditions similar to the target environment.
Recruitment

n

With the improvements to existing hydrology and soil conditions, it is expected that the
restoration sites will be populated with species from adjacent communities. The restoration
sites will be maintained to keep unwanted species at less than 15% of the total population.
6.5.3 Plant Care and Installation
The plantings will be cared for and installed based on guidelines provided in the attached
Restoration Plans. When planted properly, bare root seedlings are the most cost-effective
and successful plant material. Containerized plantings, live stakes, and other plant materials
will be used based on the needs of the planting zone (e.g., immediate shading).
6.5.4 Plant List
The plant list contained in the restoration plan is based on the target community, reference
community, and recommendations from the North Carolina Stream Restoration Institute (Hall
2001) and the North Carolina Ecosystem Enhancement Program (Smith 2004).
6.5.5 Schedule
The planting plan will be scheduled around stream construction activities and growing season.
Special attention will be paid to stabilizing disturbed areas that include newly-constructed
channels and temporary construction easements. The final vegetation planting will occur after
proper site preparation (described below and in Section 7.6) during the appropriate season.
Plantings may be staggered based on surrounding activities. Live stake planting on stream
banks (zone 1) will follow closely after channel construction to provide immediate
stabilization. Planting of zones 2-4 should occur from late winter to early spring (February 14
to April 15) in order to minimize or eliminate threats from the construction, exotic vegetation
treatment, and unpredictable weather. Any treatment of problem areas should also occur
between later winter and early spring.

6.5.6 Stabilization
Immediately after construction, the contractor will seed the stream banks and all disturbed
areas with permanent and temporary seed mixes. Permanent seeding will be completed in
conjunction with construction with temporary seeding applied per Land Quality Section
requirements contained in the approved erosion control plan. Within the stream channel (Zone
1), the contractor will plant pioneer species that provide immediate bank stabilization. The
contractor will plant live stakes and bare roots around structure installations and the outside of
meander bends to provide an area of high density root mass. Coir fiber matting and live stakes
will be used along the entire reach of the restored channels to provide stabilization until
vegetation can be established.
6.5.7 Site Preparation
The site currently contains minimal riparian buffer therefore site preparation prior to planting
will not be necessary for the upper and middle segments of the project. During construction of
the lower segment, efforts will be made to preserve as many native trees as possible.
6.5.8 Planting Review
After the final planting is complete, the planting supervisor will verify that the site was
planted properly though inspection of stem counts and condition. After completion, the
planting contractor will be responsible for replacing damaged plantings.

Monitoring will verify that the restoration area is meeting restoration goals. Damaged
' plantings will be removed and replanting will occur if the plant survival rate fails to meet
restoration goals numbers specified in section 7.2. The monitoring plan to evaluate the
success of the stream restoration project is based on guidance provided by The Stream
Mitigation Guidelines prepared by the United States Corps of Engineers -Wilmington
District and recommendation from the Ecosystem Enhancement Program.

7.0 Performance Criteria
The monitoring plan to evaluate the success of the stream restoration project is based on
' guidance provided by The Stream Mitigation Guidelines prepared by the United States Corps
of Engineers -Wilmington District and recommendation from the Ecosystem Enhancement
Program.
7.1 Stream Success Criteria
' The stream geometry will be considered successful if the cross-section geometry, profile, and
sinuosity are stable and reach a dynamic equilibrium as well as being in the geomorphic
ranges of the reference reach. It is expected that there will be changes in the resultant cross
sections, profile, andlor substrate composition. Changes that may occur during the monitoring
period will be evaluated to determine if they represent a movement toward a more unstable

condition (e.g. down cutting, erosion, etc.) or are changes that represent an increase in
stability (e.g. settling, vegetative changes, coarsening of bed material, etc.).
An initial, though not exclusive, indicator of success will be adherence to design or reference
' ratios of stream geometry found in the morphological table (Restoration Table 1) or are
comparable to the stable reference system.
Deviation from the design ratios will not necessarily denote failure as it is possible to
maintain stability and not stay within the exact design geometry. Additionally, determination
of true bankfull will be difficult until the stream has had adequate flooding events to create
strong bankfull indicators. The following key indicators of stability provide a more complete
picture of stream stability:
^ Stream Type: Maintenance of the design stream type or progression or conversion to
' stable stream type such as C or E will indicate stability
^ Bank Height Ratio: Bank height ratio between 1.0 and 1.1 will indicate flood flows have
access to the active floodplain and that higher flows do not apply excessive stresses to
stream banks
The nature of the watershed presents challenges to stream restoration. The contributing
' watersheds lie within a rapidly developing region. The urbanizing watershed's runoff
character will continue to change as the nature of the land cover shifts to less permeable
surfaces. The hydrograph will shift such that bankfull flooding events will become more
frequent and peak discharges will be higher. The cross sections have been designed with
bankfull benches to account for some shifting in bankfull discharges.
Upstream construction activities driven by land development likely will lead to episodic
' sediment pulses sent downstream through the stream network. Additionally, erosion of
upstream unstable stream banks will persistently contribute sediment to the project reaches.
The designer anticipates that the excess sediment will either be routed though the project area
' or deposited in target areas such as point bars and the floodplain. Minor sedimentation of
pools and glides may occur. The pools are designed to be over dug to account for some
sedimentation of pools and glides.
' If a large storm event occurs before the woody vegetation has established, isolated bank
erosion may occur in sections where the flood prone area has been restricted due to
' topography and/or utility easements. Areas of bank erosion should be repaired as necessary.
7.2 Vegetation Success Criteria
The initial success of riparian vegetation planting will be evaluated based on herbaceous
cover as the site is stabilized in the initial growing season. After the year-two growing
season, success will be gauged by stem counts of planted species. Stem counts of over 320
' trees per acre after 3 years, 288 trees per acre after 4 years, and 260 trees per acre after 5 year
will be considered successful. Photos taken at established photo points should indicate
maturation of riparian vegetation community.

7.3 Schedule/Reporting
' Upon completion of the restoration project, an as-built survey will be conducted that
documents the following conditions:
' Geomorphology (dimension, pattern, and profile)
^ Channel materials
' Channel stability and in-stream structure functionality
^ Vegetation
' The survey of channel dimension will consist of permanent cross sections placed at two cross
sections (one riffle and one pool) per unique stream segment, for a total of six cross sections.
The cross sections will represent approximately 50% riffles and 50% pools. Annual
' photographs showing both banks and upstream and downstream views will be taken from
permanent, mapped photo points. The survey of the longitudinal profile will represent distinct
areas of restoration and will cover a cumulative total of 3,000 linear feet of channel. Newly-
established meanders within the 3,000 foot longitudinal profile reach will be surveyed to
' provide pattern measurements. Channel material measurements will be collected by using
pebble counts at six permanent cross sections.
' The entire restored length of stream will be investigated for channel stability and in-stream
structure integrity. Any evidence of channel instability will be identified, mapped, and
photographed. All structures will be inventoried for functionality and photographed.
The success of vegetation plantings will be measured through stem counts. Permanent
quadrants will be used to sample the riparian buffer and restoration wetlands. The primary
quadrant will cover 100 square meters for tree counts. Within the primary quadrant, a 25-
square-meter quadrant will be placed to count shrubs
and a 1-meter
uadrant will b

measure herbaceous coverage. During the counts, the health of the vegetation will be noted. In
addition to stem counts, the samples will inventory species to allow for comparison between
the reference and restoration wetlands and track the population of the nuisance species. The
vegetation survey will occur during the growing season. Permanent photo points will be set up
for each quadrant.

' REQUEST FOR QUALIFICATIONS
CONSULTING ARCHITECTURAL AND
' ENGINEERING SERVICES FOR INTERIM
HISTORIC COURTHOUSE RENOVATIONS
' 1.0 Generallnformation
1.1 The objective of this Request for Qualifications (RFQ) is to solicit interest
' and credentials from qualified consultants to provide various architectural
and engineering design services far the renovation of an existing building
.located in downtown York, South Carolina. This four-story, brick building
was originally constructed in 1914 as the county's main courthouse and
has had two major additions in 1941 and in 1954. York County plans to
renovate this historic 31,000 square foot building to provide general office
' space.
1.2 York County intends that responses to this RFQ wiU be used to determine

' .the relative qualifications of various Proposers to perform the work and
tasks .specified. The county, is seeking a firm with appropriate expertise
and demonstrated experience in architectural design, historic building
renovation and the- preparation ,of documents from schematic design
' through the construction administration phases: This Request is for.-design
services only. !t is anticipated that an agreement (AIA B141 Owner-
Architect Agreement) for professional' services will be negotiated and
executed between York County and the Proposer who is determined to
best meet the needs of the county for this project. As described in more
detail in section 2.0 (Background/Scope of Work), the county anticipates
' the completion of renova#ion work in two distinct, yet coordinated phases.
While this Request is seeking firms who are interested and qualified to
provide architectural services for only the first phase of work, the county
would like to be able to consider the same firm for completion of both
phases of renovation work.
' 1.3 To ensure the integrity of the competitive process, all Proposers should
avoid contacting any public officials or department(s) other than the
person(s) listed below either directly or indirectly. Questions regarding the
scope of services for this RFQ should be in writing and directed to Glenn
Ware, Facilities Program IVlanager, at the below address. The deadline for
submitting questions regarding this RFQ is January 15, 2007. All
' responses to questions, including any significan# changes and/or
modifications to this RFQ will be placed on the York County website
(www.yorkcountygov.com) in the form of an Addendum at least one week
' prior to the scheduled submission due date. The Addendum will be shown
in the Active Bid List section of the website.

' Proposers will be responsible for any costs associated or incurred in
preparing or responding to this RFQ. All submitted responses will be
retained as property of the county and wip not be returned. The response
' must contain a manual signature of an authorized r®presentative of
the responding Proposer. Proposers will not be allowed to make any
changes, or corrections, after responses are submitted to the Purchasing:..
t Department.
1.8 Once selected, the successful Proposer will be required to provide proof of
insurance to include professional liability, workers' compensation,
' ~ employer's liability, and general liability on an appropriate Accord form
prior to commencing work.
' 1.9 All Proposers, including all employees of the Proposer, must comply with
al! applicable Federal, State and County laws pertaining to contracts
entered into by governmental agencies, including non-discriminating
employment. Contracts entered into on the basis of submitted proposal
responses are revocable if contrary to law. Contracts for work resulting

' from this Request will obligate the Proposer not to discriminate on the
basis of race, color, creed, religion, handicap, or national origin, in their
employment practices.
' 2.0 Background/Scope of Work
2.1 As previously mentioned, the courthouse building was originally
' constructed in 1914 and had major additions added in 1941 (east wing)
and in 1954 (west wing). The building is designated a °Yorkville Historical
Society Significant Site" and was listed on the National Register of Historic
' Places in 1981. In addition to not meeting present day building codes and
life safety standards, the courthouse building is not handicapped
accessible and does not comply with the Americans for :Disabilities Act
(ADA) guidelines for public buildings. While substantial physical
' modifications will be required to make the courthouse building a functional
facility,. the county would like to continue to make use of the building for
providing office space for several county departments and offices. In
contemplating the current access issues, and the need for major
renovations to address other code issues and deferred maintenance
' concerns, the county is contemplating two phases of renova#ion activities.
A. The first phase of work, planned to get underway as soon as
possible, would include efforts to address some of the major
' ADA/access issues (that would likely involve the addition of a
handicap elevator, modifications to restrooms for ADA compliance,
and possibly some modifications or updating to the building's
electrical, plumbing and mechanical systems).

' 4.4 Responses should include:
1. A copy of this RFQ's title page properly signed to include the manual
' signature of an authorized representative of the Proposer and aU
appropriate address and contact informa#ion as listed on that form.
' 2. A ie#ter of introduction and interest identifying the Proposer to include the
Proposer's primary business loca#ion, main telephone numbers, and the
length of time the Proposer has been in business, the total number of full-
time employees, names of the Proposer's principals and a complete list of
professional services offered by the Proposer.
3. A detailed summary of the Proposer's relevant experience wi#h references
and contact information.
4. Identifica#ion of all individuals who will be assigned by the Proposer to
work with York County to include a detailed summary of each individual's
professional credentials and relevant experience. This should also include
a summary of qualifications and relevant experience of all subcontractor
' personnel if applicable.
5. A detailed discussion of the desired services described in this RFQ that
' indicates an understanding of the goals and requirements of this RFQ with
specific reference as to how the Proposer would propose to accomplish
the items described to include a breakdown and explanation of services, a
proposed schedule for design through construction and any restrictions
that might be placed upon the county or the Proposer in providing those

' services.
6. Any exceptions to the terms, conditions, or other requirements in any part

The proposed stream restoration is composed of approximately 3000 linear feet of Strecker Branch. The project starts at McGill Street and ends at the
confluence with Irish Buffalo Creek (Figure 1). The goal is to return this seGfon of stream to a naturalty tunGbning system and restore the riparian habitat.
The project will create stable stream banks and provide a r'lffle•pool sequence for aquatic habitat. Since the project is located in an urban setting, stonn-
waterpractices such as level spreaders and preformed scour holes will be incorporated to treat runoff and help diffuse flow through the buffer.

Report ofLimited Groundwater Assessment- Former Pillowtex Plant #6, Concord, NC
BCE Pro,~ect No. 04-081
May Z6, 1004
Final
The unknown location of the former "filter treatment area" (No. 5) was identified b3' Mr. Raper on May
13, 2004 and in the 1963 site plan in the western end of building 4A. A dyeing operation was reportedly
located adjacent to the "filter treatment area." Due to the potential for adverse impact from dyeing
operations and wastewater treatment this area was identified as a "suspect" area for additional assessment.
The flammable liquids warehouse (No. 4} and former vehicle service garage (No. 7} were identified on
the 1963 site plan. Due to the potential for adverse impact from tammable liquids storage (i.e. spills etc.}
and vehicle maintenance operations (i.e. petroleum products, cleaning solvents, etc.) these two areas were
identified as "suspect" areas for additional assessment.
Information obtained from the Apri126, 1963 site plan indicated that the suspected Dye Room in building
1F of the former OId North plant, was a Slasher/Warper room. Mr. Raper indicated that starches were
generally used in these operations, and therefore were not considered a potential source of environmental
concern. In addition, Mr. Raper reported that the concrete foundations and grade slabs of the former OId
North Plant are still in place and the shallow groundwater in those areas could not be accessed with the
drilling equipment available.
On May 13, 2004, building 2G, which had previously been understood to contain "wet chemical
operations", was found to have been a fmished goals warehouse and distribution facility. No evidence of
"wet chemical operations" was noted inside the building and therefore no groundwater assessment was
completed in this area.
BCE reviewed the available information regarding known underground storage tanks (USTs) at the
Subject Property. According to a Notice of No Further Action letter from the North Carolina Department
of Environment and Natural Resources (NCDENR) dated October 3, 2001, eighteen (i8) 20,000.gallon
heating oil USTs were permanently removed without evidence of a release in September 200I.
According to a January 13, 1997 letter from Fieldcrest Cannon, Inc. to NCDENR, releases from a 550-
gallon diesel and a 10,000-gallon gasoline UST were reported at the time of tank removal in October
1989. A release from a 550.gallon gasoline UST was also reported at the time of tank removal in April
1992. A Notice of No Further Action letter from NCDENR pertaining to the Pollution Incident #6183 for
these two reported releases stated that based on the information provided regarding soil and groundwater
contamination at the site, no further action was required. The S&ME Phase I ESA ident~ed twenty two
(22) USTs registered USTs at the site. Based on our review of the available records, one 500-gallon fuel
oil UST installed in 1971 is unaccounted for. According to the S&ME Phase I ESA, and Mr. Raper, all

Laboratory analytical testing of the groundwater samples collected did not detect the presence of volatile
organic compounds (VOCs) at concentrations above laboratory detection limits. Various metals were
detected from select groundwater samples. The concentrations of metals detected do not exceed the
Notch Carolina 2L Groundwater Quality Standards and appear to be normal. Sulfates and nitrates were
detected in the sample collected from temporary monitoring well TW-7. The concentrations detected to
not exceed the 2L standards for sulfates and nitrates. Fecal coliform was not detected above laboratory
detection limits in the sample collected from temporary monitoring well TW-7.
3. CONCLUSIONS
The purpose of this preliminary groundwater assessment at the Subject Property was intended to identify
specific contaminants associated with past activities at the site identified to BCE, in general locations
identified through a review of a Phase I ESA of the site completed by S&ME in August 2003, information
obtained from persons familiar with site operations and a limited survey of the existing site conditions.
The sampling and analytical testing completed as part of this preliminary assessment did not identify
groundwater contamination at the site by the analyzed constituents. The results of the laboratory analysis
did not detect the presence of VOCs or priority pollutant metals in the groundwater samples collected
from the on-site temporary groundwater monitoring wells at concentrations above the applicable North
Carolina 2L Groundwater Quality Standards. In addition, concentrations of sulfates and nitrates detected
in temporary monitoring well TW-7 also did not exceed the applicable 2L Groundwater Quality
Standards, although the presence of these compounds is indicative of unidentified subsurface decaying
organic matter.

Re: Stricken Branch Stream Restoration Site,
Concord, Cabamis County, North Carolina
Dear Mr. Suiter:
Kimley-Horn and Associates, Inc. is writing this letter on behalf of our client,
Mid-Atlantic Mitigation, LLC, to request a no effect determination from your
agency regarding a proposed stream restoration site.
The Stricken Branch Stream Restoration Site is Located in Cabarrus County,
Concord, North Cazolina (Figure 1). The site is located in an urbanized EEP
Targeted Watershed (03040105020040) and consists of a highly unstable,
incised, and straightened stream channel -except for the upper portion of the
project area, which was impounded as a former water supply source for the
former textile mill.
The project will create stable stream banks and ariffle/pool system, as well as
provide the opportunity to establish root mass that provides bank stability and
habitat from the edge of the water throughout the flood plain. The project will
seek to reestablish the riparian flood plain corridor with native forest vegetation
and microtopography. The plan will also incorporate the use of stormwater best
management practices, such as level spreaders and pocket wetlands, to attenuate
and treat runoff from the surrounding developed /developing areas. Heavy
equipment will be brought in to aid in restoring natural channel pattern and
profile.

Cabazrus County. The endangered species are the Carolina heelsplitter
(Lasmigona decorata) and Schweizutz's sunflower (Helianthus schweinitzic~.
The Federal species of concern are the Carolina darter (Etheostoma Collis Collis),
Pee Dee crayfish ostracod (Dacrylocythere peedeensis), and Heller's trefoil
(Lotus helleri~. Preliminary field investigations did not identify suitable habitat
' for any of the species listed as federally endangered or federal species of concern.
Additional investigations will be conducted for each of these species and their
appropriate habitat requirements as part of the restoration plan.

Endangered/Threatened Species -Stricker Branch Sfream Restoration
Federal law under the provisions of Section 7 of the Endangered Species Act (ESA) of 1973, as
amended, requires that any action likely to adversely affect a federally protected species be
subject to review by the U.S. Fish and Wildlife Service. A search of the US Fish and Wildlife
Service website (endangered.fws.gov) and the North Carolina Natural Heritage Program
website (http://207.4.179.38/nh~/) identified two federally listed species for Cabarrus
County. The species, their habitats, and status are described below in Table 2. A review
of the project area and surrounding habitat by KHA biologists determined that the habitat
for these listed species is marginal within the project area. The National Heritage
Program database did not indicate any documented occurrences of these species within a
one mile radius of the project area. Field investigations indicated suitable habitat for
Schweinitz's sunflower (Helianthus schweinitzii) within the site. However, the proposed
construction activities would be in areas outside of this potential habitat (i.e. excavation
of stream banks to create a natural floodplain) and therefore would have no effect. The
substrate of Stricker Branch is similar to the substrate of streams containing known
populations of Carolina heelsplitter (Lasmigona decorate). Carolina heelsplitter is only
known to occur in six small streams and one small river in North Carolina. The status of
the Carolina heelsplitter in Cabarrus County is listed as "Historic", meaning the species
was last observed in this county over 50 years ago. A scoping letter requesting comments
from USFWS was submitted on July 17, 2006. As of this submittal, no reply has been
received. A copy of this letter is included in the CE submittal.

' RE: Stricker Branch Stream Restoration Site, Cabarrus County
Dear Mr. Cousins:
This correspondence is in response to your letter of August 7, 2006 concerning the referenced stream
restoration proposal, The North Carolina Wildlife Resources Commission (NCWRC) is authorized to
comment and make recommendations which relate to the impacts of this project on fish and wildlife
through the Federal License of Water Resource Project Act (Federal Power Act-16 U.S.C. 791a et seq.),
and the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d).
The project is located in the Concord area in an urban watershed. The stream is indicated to be highly
' unstable, incised and straight.
Based an our review, we have not found any federally listed threatened yr endangered animal species
indicated for the proposed work area. Accordingly, we have no objections to the proposed restoration
', providing that state-of-the-art natural channel design methodologies and autochthonous plants are used
for the project. You should also corrtact the NC Natural Heritage Program and the US Fish and Wildlife
Service to ascertain that they have no concerns for listed plants and animals under their purview. All
activities must follow US Army Corps of Engineers Permit and NC Division of Water Quality
' Certification requirements and any other special conditions specified by the NC Department of
Environment and Natural Resources. Stormwater management should be provided by local authorities to
' maintain current hydrographic conditions to prevent future destabilization of the restored stream.
Thank you for the opportunity to comment on this proposed restoration site dunng your early planning
stages. if you have any questions regarding these comments, please contact me at 336/769-9453.

Appendix 6
No-Rise Certification Letter to the City of Concord

December 21, 2006
Margaret Pearson
Director of Development Services
City of Concord
City Hall Annex
66 Union Street, South
Concord, NC 28025
Re: Stricker Branch No Rise Certification
Dear Margaret:
Mid Atlantic Mitigation is under contract with NCDENR to deliver the
restoration of approximately 3,000-feet of Stricker Branch, extending from
McGill Avenue to Irish Buffalo creek (see attached figure). The upper section of
Stricker Branch currently includes an inline pond which discharges through a
concrete spillway. This restoration plan includes restoring the historic natural
channel through the pond. The remainder of the stream, from the pond to Irish
Buffalo Creek, will consist of natural channel design with the addition of length
and excavating to provide additional conveyance, reduce erosion and improve
water quality. The proposed culvert replacement at Sign Drive was also
considered in the restoration of Stricker Branch and Mid-Atlantic Mitigation has
been coordinating with the City of Concord to incorporate the culvert
replacement into the restoration plan.
A summary of the no-rise analysis is listed below.
' Methodolo~v•
• Army Corps of Engineers HEC-RAS version 3.1.3 was used to model the
existing and proposed conditions for the reach.
• RiverCAD XP, created by Boss International, was used to cut the cross
sections based on a site survey provided by Mel Thompson and
Associates and supplemented by 2-foot contours obtained from the North
Carolina Department of Transportation GIS Library for Cabarrus County
(see attached figure for cross section location).
• There was no existing base flood elevations determined; therefore, KHA
created an existing conditions model for comparison purposes.

Margaret Pearson, December 21, 2006, Pg. 2
ASSUri]gt10DS'
• It was assumed that the manning's n would vary between 0.06 and 0.038,
with 0.06 representing a woody vegetated area, 0.045 for shrubs/grasses,
and 0.038 for the sand and cobble in the channel.
• The United States Geological Survey National Flood-Frequence Program
urban regression equations (January, 2002) were used to calculate the 10
year ] 0% and 1 % chance event. These calculations were based on a
drainage area of 1.6 square miles and 35% impervious area, calculated
using aerial photograph.
• The existing HEC-RAS model was executed using the two existing 60-
inch reinforced concrete pipe culverts located at Sign Drive. The
proposed model incorporated the proposed Conspan arch with a span of
20-foot and a rise of 9-foot along with two 15-inch corrugated metal
floodplain pipes.
• The model was executed with a known water surface elevation of 598-
feet above sea level as the downstream boundary condition. The water
surface elevation was obtained from FEMA Panel 3702500081D dated
November 2, 1994.
Results•
The criterion for a no rise certification states that there shall be no more than a
0.0 foot rise within the 100-year floodplain. The model shows that there will be
no rise in the 1 % chance event, created as a result of the proposed construction
activities within the project study area. See attached table for detail comparison
of water surface elevation.
