RE: FINAL PROSPECTUS FOR CAPE FEAR 02 UMBRELLA STREAM MITIGATION
BANK
Dear Mr. Bailey,
It is with great pleasure that Restoration Systems LLC submits the accompanying
Final Prospectus ( "Prospectus ") for the Cape Fear 02 Umbrella Stream Mitigation
Bank ( "Bank "). The Bank is proposed as a multi -phase project: eight sites constitute
"Phase I "; all future phases will consist of sites that have not yet been secured or
identified. The accompanying Prospectus provides preliminary descriptions of
existing and proposed conditions at all Phase I sites. In addition, the Prospectus
discusses a series of general provisions and requirements of the proposed umbrella
banking instrument.
We recognize that an umbrella stream mitigation bank is an uncommon occurrence in
the Wilmington District. We have therefore attempted to provide as much
information as possible at this stage in the process. We hope that you find the
Prospectus's contents adequate and complete.
We are prepared to assist you in coordinating site visits for our Phase I properties.
Please keep in mind that there are eight Phase I sites; therefore the field visits will
likely require two days. Please reach out to us with suggested dates at your earliest
convenience.

Finally, hardcopies of the Prospectus have been shipped directly to each project IRT
member copied at the bottom of this letter. Please contact Adam Riggsbee (512 -970-
3062) or Worth Creech (919- 389 -3888) to make field site visit arrangements and any
other needs relating to the Prospectus that you may have. Thank you in advance for
your consideration of our Prospectus. We look forward to receiving IRT comments in
approximately 90 -days.

2 ESTABLISHMENT AND OPERATION
2.1 Umbrella Mitigation Banking Instrument
The Sponsor is proposing to permit the Bank using an umbrella mitigation banking
instrument ( "UMBI ") As proposed, the UMBI would,allow for the establishment and
i
operation of multiple phases. Phase I is described in this prospectus and, if
Restoration Systems LLC 3 Cape Feat 02 Umbi ella Prospectus
d:
approved, will serve as the Bank's first source of mitigation credit The Sponsor also
proposes the incorporation into the Bank of additional sites not yet identified
(within the Geographic Service Area described in the next section), following
Interagency Review Team ( "IRT ") review and approval
2.2 Credit Determination
Credit for Phase I, and all additional phases, shall be based on the U S Army Corps of
Engineers (USAGE) most current mitigation credit determination methodology.
Presently, the USACE is utilizing the Stream Mitigation Guidelines (USACE 2003) to
quantify mitigation project credit potential If other methods are released and
become de facto requirements for stream mitigation projects in the USACE, future
phases will utilize these methods, as appropriate.
2.3 Riparian Buffer and Nutrient Offset Credits
In April 2013, the Sponsor+and.the North Carolina Department -of Environment and
Natural °Resources ( "NCDENR ") entered into an Agreement to Establish an Umbrella
Mitigation Banking Instrument in the Cape Fear River Basin for Riparian Buffer and
Nutrient Offset Mitigation Credits Pursuant to the Jordan Lake Nutrient Strategy
( "Buffer UMBI ") The Sponsor may choose to generate and sell buffer or nutrient
credits from any site(s) permitted under the UMBI proposed here Such generation
and sale of buffer or nutrient credits must be approved by NCDENR, and shall be
pursuant to all terms and conditions of the Sponsor's Buffer UMBI
2.4 Credit Release Schedule
Credits generated by actions, described and "approved in the Bank's final UMBI shall
be released,in predetermined increments according to the milestones agreed to by
the Sponsor and the'I,RT in the UMBI's credit release schedule. The Sponsor will use
the credit release schedule detailed.for stream mitigation banks in USACE (2013)
3 GEOGRAPHIC SERVICE AREA AND USE OF CREDIT'S
Located, within the Piedmont level III ecoregion and the Upper Cape Fear River
basin, the Bank's geographic service area ( "GSA ") is defined. by the United States
Geological Survey (USGS) 8 -digit Hydrological Unit Code ( "HUC ") within which the
Bank's sites are located, the Cape Fear 02 (Figure 3)
The Bank's credits are proposed to be used to offset unavoidable, permitted impacts
within the Bank's GSA Use of the Bank's credits outside of its GSA may be
permissible with approval by the USACE, which will be considered on a case -by -case
basis.

4 WATERSHED CONSIDERATIONS
4.1 Watershed Environmental Concerns and Mitigation Needs
The Cape Fear River basin is one of four rivers in North Carolina completely
contained within the state's boundaries. Comprised of five major drainages —Haw
River, Deep River, Northeast Cape Fear River, Black River and the Cape Fear River —
the basin drains portions of 26 counties and 115 municipalities with a total of 6,386
stream miles The most populated portions of the basin are located in the Triad, the
Triangle, Fayetteville, and Wilmington (NCDWQ 2005).
Nearly all of the Cape Fear 02 drains into B ,Everett Jordan Lake ( "Jordan Lake "),
which is designated as impaired due to excessive levels of chlorophyll a according to
state water quality standards Stressors to Jordan Lake's water quality are
associated with nitrogen and phosphorus inputs from point sources, especially
municipal wastewater, and non -point sources such as urban stormwater runoff'arfd
rural agricultural runoff Most of the impaired streams, in the Cape Fear- 02 are
located in heavily urbanized,areas
Between the 2000 and 2010 censuses, the Cape Fear 02 population increased
approximately 17 percent (Table 5). The general trend of population growth
appears to be continuing according to recent population estimates, which indicate
Guilford, Orange, Chatham and Durham counties are all growing at faster annual
rates than the state's 102 percent (,USCB 20,13) These data suggest land
development activities will increase in frequency, as will aquatic ecosystem impacts
related to such development Therefore, there is an immediate and prolonged need
for compensatory stream mitigation in the watershed. Of further benefit, aquatic
ecosystem restoration projects are capable of reducing nutrient loading in sensitive
downstream receiving waters such as Jordan Lake.

4.2 Bank Site Selection
Based on the analysts presented in Section 41, the Cape Fear 02 was targeted as a
watershed in need of stream mitigation The Sponsor and its consultant, Axiom
Environmental, Inc (Axiom), conducted a search for sites possessing stream
restoration and enhancement opportunities. Identified sites were prioritized based
on geomorphic condition and land use, and the necessary landowners were
contacted to gauge their interest in participating ,in a stream mitigation project. Sites
with willing landowners were then pursued further As real estate in the area is
generally well subdivided, many of the identified opportunities are not currently
feasible because such sites require the cooperation' of several landowners in order
to achieve sufficient ecological and economic-scale. Therefore, selection of the Phase
I properties was based on a combination of geomorphic condition, land use, and the
willingness of landowners to participate
5 OWNERSHIP AND LONG -TERM MANAGEMENT
The Phase I properties are an assemblage of portions of larger holdings currently
owned by the following people, or organizations,
Motes Creek - Thomas, Roger, and Patricia Dodson of Alamance County;
Benton Branch - Dennis Simmons of Caswell County;
Orphan Creek - Mr and'Mrs Williamson of Alamance County,
Chico Branch - Billingsley & Associates of Rockingham County;
Major Hill - Jim Lamm of Alamance,County;
Maple Hill Farm'- Joe and Tish Murray of Alamance County,;
Rocky Top - Jim Lamm of Alamance County; and
Slingshot Creek - Robert Wheless of Rockingham County
Hereafter, these owners will collectively be referred to as "the,Landowners.
The Sponsor and the Landowners have executed separate Agreements for Purchase
and Sale of Conservation Easements coveting approximately 19 -acres along Motes
Creek, 30 -acres along Benton Branch, 14.5 -acres along Orphan Branch, 8 -acres
Restoration Systems LLC 6 Cape Fear 02 Umbi ella Pi ospectus
along Chico Creek, 11 1 -acres along Maple Hill Farm, 10 -acres along Major Hill, 5 2-
acres along Rocky Top, and 13 -acres along Slingshot Creek. Following USACE
approval of the UMBI and the Phase I Mitigation Plan, the Sponsor will exercise its
rights provided under the above - referenced agreements.
The Phase I properties will be protected in perpetuity by conservation easements
approved by the USACE. At a minimum, conservation easements will be written to
prohibit incompatible uses that might jeopardize objectives of the Bank During the
operational period of each site,:the Sponsor may hold the conservation easements.
Once a Bank site is closed out, easements will be transferred to a-qualified land trust,
such as ,the North Carolina Wildlife Habltat,Foundatlon, to be held in +perpetuity The
Sponsor will provide the land trust with a f nancial,sum, in an amount agreeable to
both parties, appropriate for the long -term stewardship of the sites
During the operational period ,of a Bank site, the Sponsor will be responsible for
management actions Following Bank close out, the Landowners will serve as long-
term managers of the sites, and the land trust holding conservation easements will
routinely monitor the sites to ensure the Bank's conservation easement terms are
not violated Other long -term management responsibilities will include protecting
the sites from encroachment, trespass, clearing, an_d other violations that interfere
.with conservation purposes. Fencing, suitable to prevent livestock grazing within
easement boundaries, will be constructed as necessary Conservation easement
boundaries will be clearly�marked prior to transfer.
6 QUALIFICATIONS,OF'SPONSOR
Restoration Systems is an environmental restoration, mitigation banking and full -
delivery mitigation firm founded in 1998 The firm was formed to improve the
quality of environmental restoration and mitigation by locating and acquiring the
best available sites, planning restoration using proven science, and constructing
sites with the most qualified contractors Restoration Systems' staff has been
involved in environmental mitigation and mitigation banking since '1992 Project
managers have more than 80 years of experience in resource evaluation,
environmental restoration, and mitigation implementation The company employs 9
permanent staff members based in Raleigh, North Carolina.
Corporate experience with the principals began with completion of the state's full -
delivery, mitigation project in 1997, the Barra Farms Mitigation Bank (623- acres),
the, subsequent Bear Creek —Mill Branch Mitigation Bank in 2001 (450- acres), and
Sleepy Creek Mitigation Site (55&-acres) The firm then performed all of the off -site
mitigation (7500 -LF of stream restoration and 10 -acres of wetland restoration) for
the Piedmont Triad International Airport Authority.
Restoration Systems has implemented projects for the NCEEP, formerly the North
Carolina Wetland Restoration Program; including the removal of the Carbonton and

Site, and thr-oyghout,the southern United States.
7 ECOLOGICAL- SUITABILITY OF S_ ITES
Primary considerations for�selectmg the Phase I sites included the potential for
protection /improvement of water quality within a region of.North Carolina under
heavy development and livestock /agricultural .pressure. More specifically,
considerations included desired aquatic resource- functions, hydrologic conditions,
soil characteristics,, aquatic habitat diversity; habitat connectivity, compatibility
with, adjacent ° land uses, reasonably foreseeable effects the mitigation projects will
have` on - ecologically important aquatic and terrestrial` resources, -and -potential
development trends and land use changes
As all Phase I sites are located in Cape Fear 02, the current agricultural land uses at
these sites may contribute nutrients to Jordan-Lake (NCDWQ 2'005). Restdrationn and
enhancement work proposed in the Restoration :Plan (Section 10) will reduce
existing nutrient�and sediment loads to downstream.waters. In addition, restoration
work will improve °in - channel aquatic,and riparian habitats.
8 FINANCIAL ASSURANCES

This hydrophysiographic region is characterized by moderate rainfall with
precipitation averaging 43 7 -inches per year (based on data provided by NOAA
2014) Site discharge is dominated by a combination of upstream basin catchment;
groundwater flow, and precipitation. Based on regional curves (Harman et al 1999),
the bankfull discharge,for a 0,71- square mile. watershed is expected to average 70-
cubic feet per second (CFS). Based on empirical evidence a bankfull discharge of 70-
CFS is expected to occur approximately every 1.3 to 15 years (Rosgen 1996,
Leopold 1994)
9.1.6, FluvialZeomorphology ,
Currently; channels'targeted for restoration are characterized as entrenched and /or
incised G -type or C -type channels with little to no sinuosity, little to no riffle -pool
morphology, oversized cross - sectional areas, and no access to floodpl'ains during
high discharge events (Bank Height, Ratio (BHR) range > 1.3 to 2.4). Sinuosity was
measured at 1.05 from topographic surveys, aerial photography, and visual
observation during field surveys.
In general, sediment and nutrient inputs, channel incision and straightening,
livestock trampling, removal of cobble substrate, aggradation of silt and sand, and
removal of woody vegetation have impacted Motes Creek site streams.
9.1.7 FEMA
Inspection of the FEMA Flood Insurance Rate Map 371O9811O0J, Panel 9811,
effective September 6, 20,06, indicates that -Motes Creek streams are not located in a
Special Flood Hazard Area, and the project should not alter FEMA flood zones
Therefore, a "Conditional Letter of Map Revision" (CLOMR) is not necessary for this
site
9.2 Benton Branch
The Benton Branch site is characterized by disturbed forest and agricultural1arid
used for livestock grazing and hay production (Photo 2). The main hydrological
features include Benton Branch and six UTs to Benton Branch. Several of these
streams have impoundments in the headwaters reducing the frequency and

With the exception of Benton Branch, the site's tributaries are depicted as
intermittent on the USGS 7 5 -minute topographic quadrangle_ However, UT 4, UT 5,
and UT 6 exhibit field characteristics of perennial streams These tributaries have
drainage areas encompassing 0.13, 0 68, and 124- square miles; respectively, and
the channels are well defined with cobble substrate. In addition, benthic
macroinvertebrate samples collected in the upper reaches of UT 4 using the Qual -4
technique support a perennial flow regime designation (stonefly larvae)
UT 2 and UT 3 are not mapped by the USGS, however-, field evidence — including
benthic macro inverteb rate samples, NCDWQ Stream Identification Form [v411]
scores, and evidence of stream flow during field visits — indicates the channel's are
intermittent to perennial UT 1, UT 2, and UT 3' all 'exhibit characteristics of
perennial flow in the upper reaches However, ponds upstream from the stream
origin point, low slope of floodplain, livestock impacts to channels, and antropogenic
alterations to the floodplain and channels have resulted in loss of stream channel
morphology in the downstream reaches.
This hydrophysiographic region is characterized by moderate rainfall with
precipitation averaging 43 4- inches per year (based on data provided by, NOAA
2014) Site discharge is dominated by a combination of up_ `stream basin catchment,
groundwater flow, and precipitation Based on regional curves, the bankfull
discharge for a 0 3- square mile and 9 1- square mile. watershed are expected to
average 7.8 and 439 -CFS, respectively (Harman et al. 1999). A_bankfull discharge is
expected to occur approximately every 13 to 1.5- years (Rosgen 1996, Leopold
1994).
Restoi aeon Systems LLC 15 Cape Fear 02 Untbt ella Prospectus
9.2.6 ,Fluvial,Geomorphology
Currently, two distinct stream types characterize channels targeted for restoration
One is an entrenched and`` /or incised G -type or F -type channel with sinuosity
affected by bank erosion and hoof shear. Riffle -pool morphology has been
compromised by sedimentation and bank collapse due to a lack of deep. Footed
vegetation These channels are oversized with no access to floodplains during high -
discharge events (BHR = 3.6)
A second stream type ,includes streams without existing channels due to
aggradation resulting from livestock trampling, vegetative clearing, removal of
channel substrate, and channel rerouting Headwater ponds further affect some of
the channels in this category. 'Ponds in the upper reaches of UT 1, UT 2, and UT 3
appear to attenuate storm flows, thereby reducing sediment rnobilization Reduced
sediment transport and intensive trampling of channel bed and banks by livestock
has produced aggraded channels characterized as wide, compacted sloughs without
defined beds or banks.
9.2.7 FEMA
Inspection of the FEMA Flood Insurance Rate Map 371089600K, Panel 8960,
effective September 28, 2007, indicates that Benton Branch, UT 3, and associated
floodplains are located within a Zone AE flood area. Therefore, a HEC -RAS analysis
will be completed on the existing and proposed conditions of Benton Branch and its
tributaries that enter the Benton Branch floodplain to assess hydraulic performance.
As per N.C. Floodplam .Mapping requirements, a Conditional Letter of Map Revision
(CLOMR) will need to,be�prepared for the site.
The CLOMR includes written documentation of modeling, preparation of
topographic work, maps, annotated FIRM or Floodway Maps, FIRM Flood Profiles
and Data Tables The CLOMR will be sent to, Caswell County for approval and
signature, and then the CLOMR will be sent to FEMA for review, and,approval The
CLOMR approval prpcess will take 3 -6 months The. CLOMR should be prepared,
submitted and approved prior to construction A requirement of the-CLOMR is to
prepare, and submit'atetter of Map Revision (LOMR) once construction is complete.

This hydrophysiographic region is characterized by moderate rainfall with
precippnon averaging 43 7- inches per year (based on data provided by NOAA
2014). Site discharge is dominated by a combination of upstream basin catchment,
groundwater- flow, and precipitation. Based on- regional curves (Harman et al 1999),
the bankfull discharge for a 0.2- square mile watershed is expected to average 27.7 -
CFS A bankfull discharge evenvis expected to occur approximately every 1.3 to 1.5-
years (Rosgen 1996, Leopold 1994)
9.3.6 Fluvial Geomorphology
Currently, channels targeted for restoration are,c_haracterized as entrenched and/pr
incised G' -,type or.F - type channels with little to no sinuosity, little to no riffle -pool
morphology, oversized channel cross - sectional areas, and no access to flo6dplains
during high discharge events ,(BHR range > 2.2 to 2 7). Sinuosity was measured at
10,2 using topographic surveys, aeal photography, and visual observation ri during
field surveys.
In general, the streams comprising the Orphan Creek site have been impacted by
excavation of a =k- ened, channel, excessive sediment and nutrient inputs,
channel incision, trampling, removal of cobble substrate, aggradation of
silt and prid, and removal of woody. vegetation.
9.3.7 FEMA
Inspection of the FEMA Flood Insurance Rate Map 3'' 10980100J, Panel 8901,
effective September 6, 2006, indicates that Orphan Creek streams are not located in
a Special Flood Hazard Area, and the prol,ect should not alter FEMA flood zones
Therefore, a "Conditional Letter of Map Revision" (CLOMR)'is not necessary for this

high of 720 -feet NGVD at the upper reach of UT 1 to a low of approximately 690 -feet
NGVD at the site.outfall (Figure 713)
This site drains an approximately ,0.1- square mile (61 -acre) watershed` (Figure 7C)
The, watershed, is dominated, by pasture, agricultural land, sparse forest, and ,rural
residential property. Impervious surfaces account for less than five- percent of-the
upstream land surface
Land use at the site is characterized by' disturbed forest, hay fields, ,and livestock
pasture Riparian zones and wetland areas primarily support herbaceous vegetation
that is sparse and disturbed due to livestock grazing, bush hogging, and regular land
management activities.
9.4.2 Water Quality
Chico Branch is located within USGS 14 -digit HUC 0303000201001 (Figure 2) and
NCDWR Subbasin 03 -06 -01 Topographic features of the Chico Branch site drain to
Troublesome Creek (Stream Index Number 16- 6 -(3)), which has been assigned a
Best Usage Classification of WS -V, NSW' (NCDWIt 2013). WS -V streams are
protected as water supplies, which are generally upstream, and draining to Class
WS -IV waters or waters used by industry to supply their employees with drinking
water or as waters formerly used as water supply. These waters are also ,protected
for Class C uses such as aquatic life propagation and survival, fishing, wildlife,
secondary recreation, and agriculture. Secondary recreation includes wading,
boating, and other uses not` involving human body contact with waters on an
organized or frequent basis The NSW designation denotes nutrient sensitive waters,

9.4.3 Vegetation
The Chico ' Branch site is characterized primarily, Eby agricultural land, iticl'udmg
pasture and hay fields, and some areas of 'disturbed forest in the 'downstream
reaches. Fields are dominated by fescue (Festuca sp.) with sparse natural recruits
including dog fennel (6upatorium capillifolium), nightshade (Solanum sp), clover
(Trifghum sp.), blackberry (Rubus argutus), dandelion (Taraxacum sp.), as well as
other oppprtunistic herbaceous species Stream channels have been trampled by
livestock and are ,characterized by wetter species, such as rushes Uuncus spp.) and

9.4.6 Fluvial GeomorpFiology
Livestock trampling has aggraded channels targeted for restoration. These channels
are discontinuous with pockmarked soils and adjacent comp_ action resulting in
accelerated overland runoff In addition, small impoundments within the channels
result yin, an:-alternating pattern of aggradation and scour. A lack of deep- rooted
vegetation and removal, of stream substrate, combined with heavy stocking rates of
livestock with unrestricted access to the channels, results in shallow, depressions
devoid of any discernable geometry. -
An adjacent reference stream, not impacted by livestock, exhibits channel
mor- phology of an E -type channel with natural sinuosity 'The" reference channel
appears slightly smaller than regional curves; however; dimension, pattern, and
profile appear'suitable`as a'reference for the Chico Branch site.

characterize regional physiography with moderate to steep slopes and low to
moderate - gradient streams over boulder and cobble - dominated substrate (Griffith
et al. 2002). On -site elevations range from ,a high of 660 -feet NGVD at the, upper
reach of UT 1 to a low of approximately 610 -feet NGVD at the site outfall (Figure
1013)
This site drains an approximately 0.07- square mile (42- acres) watershed (Figure
10C). The watershed is dominated by pasture and forest Impervious surfaces
account for less than one - percent of the upstream land surface
Land use at the site is characterized by disturbed forest, hay fields, and livestock
pasture Riparian zones and wetland areas are primarily composed of disturbed
forest Forest areas are accessible to livestock and have a thin understory with
compacted soils. Multiple, active springs are focated;along the margins of the stream
These areas have primarily been cleared of forest vegetation and are characterized
by'herbaceous vegetation that is sparse and disturbed due to livestock grazing, bush
hogging, and regular land management activities
9.7.2 Water Quality
Rocky Top is located within USGS 14 -digit HUC 03030002050050 (Figure 2) and
NCDWR Subbasin 03- 06 -04. Topographic features of the Rocky Top site drain to
Reedy Branch (Stream, Index Number 16- 28 -3,), which has been assigned a Best
Usage Classification of WS -V, NSW ( NCDWR 2013). WS -V streams are protected as
water supplies that are generally upstream and draining to Class WS' -IV waters or
waters used by industty to supply their employees with drinking water-or as waters
formerly used ,as water, supplies These waters are also protected ,for Class C uses
such as aquatic life propagation and survival, fishing, wildlife, secondary recreation,
and agriculture Secondary recreation includes wading, boating, and other uses not
involving human body contact with waters on an organized or frequent basis The
NSW designation denotes nutrient sensitive waters, which include areas with water
quality problems associated with excessive plant growth resulting from nutrient
enrichment Reedy Branch, adjacent to the site; is not listed on the final 2012 or
draft 2014 303(d) lists (NCDW.Q 2012 and NCDWR 2014).
9.7.3 Vegetation
The Rocky Top site is characterized primarily by�agricultural land including pasture,
hay fields, and disturbed forest. Fields are dominated by fescue (Festuca sp) with

This region is characterized by moderate rainfall with precipitation averaging 43.7 -
inches per year (based on data provided by NOAA 2014) Site discharge consists of a
combination of upstream basin catchment, groundwater flow, and precipitation.
Based ,on regional. curves (Harman et-al. 1999), the bankfull discharge for. a,0,07-
square, mile watershed.is expected to average 13.0 -CFS A barikf ill discharge event
is expected to occur, approximately every 13 to 1 5 -years (Rosgen 1996, Leopold
1994).
9.7.6 Fluvial Geomorphology
Currently, channels,targeted for restoration are characterized as entrenche6and /or
incised G -type or F- type,channels with little to no, riffle -pool ye-pool
channel - cross- secfional - areas, and no access to floodplams during -high_ discharge
events (BHR range > 2) UT 2 originates from a springhead and has been ditched
along the margins of the floodplain, resulting in a sinuosity of 1.02. UT 1 retains a
reasonable sinuosity (approximately 12); however, the loss of forest "vegetation and
hoof shear-has destabilized some outer bends, resulting in a loss of pattern including
tight meander radii, shoot cutoffs, extended pools, and a loss of suitable channel
substrate
In general, sediment and nutrient inputs, channel incision and manipulation,
livestock trampling, removal of- cobble substrate, aggradation of silt and sand, as
well as removal of woody vegetation have impacted Rocky Top site streams.
9.7.7 FEMA
Inspection of the FEMA Flood Insurance Rate Map 3710878700J, Panel 8787,
effective September 6, 2006, indicates,that Rocky Top streams are not located in a

10.1 Reference Data
10.1.1 Stream Reference
At this time, site - specific reference streams have not been identified for all sites
However-, relatively undisturbed sections of stream have been identified at Chico
Branch, Maple Hill Farm, Rocky Top, and Major Hill sites Data collected at these,
reference reaches, including cross sectional data, benthic macroinvertebrate
collections, and hardwood forest composition, were utilized to approximate
mitigation potential on these sites. These reference reaches have been compared to
a database of reference sites compiled by Axiom for other restoration sites in the
area (Cedarock Park, Causey Farm Mitigation Site, and Bass Mountain Mitigation
Site) Reference data, used in, conjunction with appropriate regional curves for the
Piedmont of North Carolina-(Harman et al 1999), allowed for comparison of existing,
disturbed conditions to relatively undisturbed reference conditions at the proposed
mitigation sites.
10.1.2 Reference Forest Ecosystem
According to Mitigation Site Classification ( "MiST ") guidelines (OSEPA 1990),
Reference Forest Ecosystems ( "RFEs ") must be established for restoration sites
RFEs are forested areas used to model restoration efforts at each site in relation to
soils, hydrology, and vegetation RFEs should be ecologically stable climax
communities and should represent believed historical conditions of the restoration
site Data describing plant community composition and structure are collected at the
RFEs and subsequently applied as reference data for design of each restoration site
Reference'vegetation communities for each site have not been identified at this time.
During detailed restoration planning, a site - specific reference, forest will be located
and tree and shrub species identified in this area will be utilized, in, addition to other
relevant species to supplement community descriptions for Piedmont Low
Mountain Alluvial Forest and Dry -Mesic Oak- Hickory Forest (Schafale and Weakley
1990) Species that may occur in these vegetative communities are listed in Table 23.

10.3 Stream Restoration
Stream Restoration efforts are Intended to restore a stable, meandering stream at
new locations, imp roving'floodplain connectivity while using reference streams and
appropriate regionail ; c u,rves to design and construct natural hydrodynamics, stream
geometry, and local microtopography. Primary activities designed to restore`Phase I
channels include belt -width preparation ' and grading, channel excavation,
installation of channel plugs, backfilling of abandoned_ channels.. Installation of piped
channel crossings, and vegetative planting.;,, -
10.3.1 Belt width Preparation and Grading n I.
Care will`be taken fo'avoid the removal of existing, deeply "rooted vegetation within,
the belt -width corridor, which" often provides channel stability. Material excavated
`during grading will be, stockpiled immediately adjacent io channel segments to „be
abandoned and backfilled'following stream diversion.
Restoratloll Systems,LLC 41 Cape Feai 02 Umbrella Prospectus
Spoil material may be placed to stabilize temporary access roads and to .minimize
compaction of the underlying floodplam. However, all spoil will be removed from
floodplain surfaces upon.completion of construction activities
After preparation of the corridor, the design channels and updated profile surveys
will be developed, and the locations of each meander wavelength will be plotted and
staked along the profile Pool locations and other channel features may be modified
in the field based on local variations in the.floodplam profile
10.3.2 Channel Excavations
Channels will be constructed within the range of values developed during detailed
restoration planning. Regional curves and /or reference stream reaches (see Section
10 1 1) will be used to develop various stream geometry attributes
Stream banks and local belt -width areas of constructed channels will be
immediately planted with shrub and herbaceous vegetation to initiate stability,
preventing unintended erosion Deposition of shrub and woody debris into and /or
overhanging the constructed channels will be used to further increase each
channel's resistance to shear stress Particular attention will be directed toward
providing vegetative cover and root growth along the outer bends of each stream
meander. Live willow stakes will be purchased and /or collected on -site and inserted
through the root /erosion mat into underlying soils.
10.3.3 Channel Plugs
Impermeable plugs willbe installed along abandoned channel segments; The plugs
will consist of low - permeability materials or hardened structures designed -to, be of
sufficient strength to withstand the erosive energy of surface flow events across
each site. Dense clays, which may be imported from off -site if necessary, Will be
compacted within each channel for plug construction. Each plug will be of sufficient
width and depth to form an imbedded overlap in the existing banks,and bed.
10.3.4 Channel Backfilling
After impermeable plugs have been installed, abandoned channelswill be backfilled
Stockpiled materials will be pushed into abandoned channels. Suitable material
used for backf►lling may be derived from c n -site or off -site sources. Vegetation
debris (e&, root mats, top soils, shrubs, woody debris, etc.) will be 'redistributed
across the backfill area upon completion
10.3.5 Piped Stream Crossing
Landowner uses will sometimes necessitate the installation of piped channel
crossings to allow access to portions of the property otherwise isolated by stream
restoration activities Piped crossings will be constructed with pipes sized to
adequately pass anticipated stormwater flows with hydraulically stable riprap or
other suitable rock. Pipes will be large enough to handle the weight of anticipated
vehicular traffic. Approach grades will be at an approximate 10:1 slope and
Restoration Systems LLC 42 Cape Fear 02 llmbi ella Pi ospectus
constructed on hard, scour - resistant crushed rock or other permeable material free
of fines
10.3.6 In- stream Structures
The use of in- stream structures for grade control and habitat are essential for
successful stream restoration. In- stream structures maybe placed °in the channel to
elevate local water surface profiles, potentially flattening the water energy slope or
gradient. The structures will likely consist of log /rock cross -vanes or log /rock 1-
hook vanes designed primarily to direct stream energy into the center of the
channel and away from banks In addition, structures will be placed m relatively
straight reaches to provide secondary (perpendicular) flow cells during bankfull
events.
Log vanes may also be used to ,direct high- velocity -flows during bankfull ,events
toward the center of constructed' channels:'Log vanes will be constructed utilizing
large tree trunks harvested on -site or imported from off -site as necessary Tree
stems harvested for a log cross -vane arm must be long enough to be embedded into
the stream channel and extend, several feet into the floodplain Logs will create an
arm that slopes from the center of the channel upward to each stream bank at an
angle or 20 to 30- degrees A trench will be dug into the stream channel that is deep
enough for the head of the log to be at or, below, the channel invert. The trench is
then extended into the floodplain and the log -is set into the trench such that the log
arm is below the floodplain elevation If °the log is not of sufficient.siz_e to completely
,block,stream flow (gaps occur between the log and channel bed), a footer log will be
installed beneath the header log. SuppofVpilmgswill then be situated at the base of
the log and at the head of the log to hold the log in place. Once these vanes are in
place, filter fabric is toed into a trench on the upstream side of the vane and draped
over thfe structure to force water over the vane The upstream side of'the structure
is then backfilled with suitable material.
Drop structures will be necessary at the outfalls of some constructed channels to
match preconstruction elevations. Drop structures will be constructed out of
TerraCell, or other suitable materials, depending upon anticipated scour from the
restored stream channels. The structures will be constructed to resist erosive forces
associated with hydraulic drops TerraCell is a lightweight, flexible mat made of
high- density, polyethylene strips- The strips are bonded together to form a
honeycomb configuration The honeycomb mat is fixed in place and filled with
gravel or sand Material in the TerraCell structure may be planted with grasses and
shrubs for additional erosion protection. The TerraCell structure will form a
nickpoint that approximates geologic controls in streambeds.
10.4 Riparian Restoration
Restoration of floodplain forest and streamside habitat allows for development and
expansion of characteristic species across the landscape. Ecotonal changes between
community types contribute to diversity and provide secondary benefits, such as
Restoration Systems LLC 43 Cape Fear 02 Umbrella Pi ospectus
enhanced feeding and nesting opportunities for mammals, birds, amphibians, and
other wildlife.
Planted streamside trees and shrubs will include species with high value for
sediment stabilization, rapid growth rates, and the ability to Withstand hydraulic
forces associated with bankfull and overba_ nk ,flow events Streamside trees and
shrubs will be planted within 15 -feet of the channel throughout the meander
beltwidth Shrub elements will be planted along reconstructed stream banks,
concentrated along outer bends.
Deeply rooted' riparian vegetation will be restored as needed at all Phase I and
future sites Planting vegetation on cleared stream banks is proposed to reestablish
native /historic,community patterns within the stream corridor, as well as associated
side slopes and transition areas. Revegetating floodplains and stream banks will
provide overall system `stability, shade, and wildlife habitat. In addition, viable
riparian communities will' improve system biogeochemical function by filtering
pollutants from overland and shallow subsurface flows and providing organic
materials to adjacent stream channels
Variations in vegetative planting will occur based on topography and hydraulic
condition of soils. Vegetative species composition will be based on RFEs, site -
specific features, and community descriptions from Classification of the Natural
Communities of North Carolina (Schafale and Weakley 1990) Community
associations to be utilized include: 1) Piedmont /Low Mountain Alluvial Forest, 2)
Dry -Mesic Oak- Hickory Forest and 3) Streamside Assemblage A list of species
organized by Schafale and Weakley (1990) communities is presented below. This
list is for planning purposes only Final planting may include some or all of the

10.5 Stream Enhancement I & II
In portions of the Phase I sites and future sites, the use of restoration may not be
necessary to improve a system's ecological function In such cases; enhancement
activities will be implemented For the purposes of the UMBI, Stream Enhancement I
and Stream Enhancement II are defined per USACE, (2003)
10.5.1 Stream Enhancement I
Stream Enhancement I is expected to include cessation of agricultural activities
(including row crop production, hay production, andbr livestock grazing), removal
of invasive species, raising the channel bed elevation to reconnect bankfull stream
flows to the abandoned floodplain, and planting with native, ,woody species Stream
Enhancement I will generally entail the alteration of stream channel dimension and
profile, as the channel is lifted to the historic floodplain elevation These measures
are expected to facilitate stream dynamics associated with a natural, relatively
undisturbed stream in the Piedmont of North Carolina.
10.5.2 Stream Enhancement II
Stream Enhancement I1 is expected to include the cessation of agricultural activities
(including row crop production, hay production, and /,or livestock grazing), removal
of invasive species, and supplemental planting with native, woody tree species.
Stream enhancement II will extend a minimum distance of 50 -feet from the top of
stream banks These measures are expected to facilitate stream recovery and
prevent further degradation of the streams
11 MONITORING PLAN
The Bank's`performance standards and monitoring plan will, be based on the USACE
(2013) guidance document titled, Monitoring Requirements and Performance
Standards for Compensatory Mitigation in North Carolina. In general, the monitoring
program will be implemented for 7 years with an opportunity for an, early
termination after 5 years if a site's performance standards, as, set forth in USACE
(2013), are met Additional monitoring of each site, aside from the Bank's
performance standards, will occur -to identify ,areas to be treated by the Adaptive
Management and Remedial Measures Plan (see Section 12)
11.1 Stream Monitoring
Stream monitoring protocols. -will be developed for all reaches involving Stream
Restoration, "Enhancement II, and Enhancement I with in- channel work Protocols
will include collection of the following: longitudinal profile (collected' as part of a
Restoration Systems LLC 45 Cape Fear 02 Umbrella Prospectus
sites' as -built surveys), permanent channel cross - sections, bank pins on
predetermined outside meander bends, and crest gauges to monitor frequency,and
magnitude of bankfull events Visual assessments will be conducted by walking the
length of each channel. Preconstruction and post - construction photographs' will 'be
compiled
11.2 Vegetation Monitoring
Restoration monitoring procedures for vegetation are designed in accordance,with
CVS -EEP Protocol for-Recording Vegetation Level 1-2 Plot Sorripling Only (Version 4:2)
(Lee et al. 2008)
After planting has been completed in winter or early spring, an initial evaluation will
be performed to verify planting methods and to determine initial species
composition and density Supplemental planting and additional site modification
will be implemented'if necessary.
During the first year, vegetation will receive Visual observation on a periodic basis
to ascertain the degree of over'toppin'g'of planted elements by nuisance species, and
quantitative sampling will occur between 'September 1 and September 30.
Subsequently, quantitative sarnpIfng,of vegetation will be performed between July 1
and leaf'drop for'eachgrowing season until vegetation success criteria are achieved.
During quantitative sampling in early fall of the first year, a minimum of 4 plots '(10
meters square) or approximately 2 percent of a site's easement area, whichever,is
greater, will be randomly placed across each site. In each sample plot, vegetation
parameters to be monitored` and reported inclue species, count, height, date of
planting, and grid location of each planted stem Volunteer species encountered
during monitoring will be counted, identified to species level, measured, And
recorded.
11.3 Visual Monitoring
Visual monitoring of general site conditions that may or may not be part of „stream
and vegetation monitoring protocols will be conducted at, least twice during each
monitoring year: One visual inspection can be completed during stream and /or
_ r y
vegetation monitoring 'The other inspection will occur independently and must be
separated by at least- 5 months Monitoring will be conducted by traversing the
entire site to identify and document areas of low stem density, poor plant vigor,
prolonged inundation, native and exotic invasive species, beaver`activity, excessive
herbivory,. easement encroach'merit, indicators of livestock access, and other areas
of concern.
11.4 Water Quality and Macroinvertebrate Monitoring
Per USACE (2013), water quality and macro invertebrate monitoring will be
conducted as appropriate for each site ,to document fluctuations in various water
quality parameters and'inacroinvertebrate communities. Protocols for water quality
and macroinveriebrate monitoring will be developed for all reaches involving
Restoration Systems LLC 46 Cape Fear 02 Umbrella Prospectus
Stream Restoration, Enhancement I, and Enhancement II with, in-channel work. As
streams are products of their watersheds, and upstream pollution and land use can
negatively affect a site's water quality, the results of this particular, part. of the
Monitoring Plan may not demonstrate ecological improvements at a, given site
Therefore, these data will not be tied directly to the UMBI's performance standards
However, positive results could be useful in determining if a particular site has met
its goals and objectives
11.4.1 Water Quality Monitoring
Water quality monitoring will be conducted once to establish baseline conditions
and at least twice during each monitoring year Monitoring should be repeated at
the same times and during normal flow conditions each year to limit seasonal and
hydrological variability. Each bi- annual monitoring event will be separated by 5 or
more months Water quality parameters to be sampled include pH, temperature,
dissolved oxygen, and conductivity, which will be sampled at two locations in each
tributary exceeding 500 -LF in order to capture channel - specific input and output
values
11.4.2 Macroinvertebrate Monitoring
M acro invertebrate sampling will be conducted once before construction (baseline
conditions) and once during monitoring years 3, 5, and 7. Sampling will be
conducted according to the "Qual 4" method described in Standard Operating
Procedures for Collection and Analysis of Benthic Macromvertebrates (NCDWQ 2012)
In addition, sampling should occur during the "index period" referenced in Small
Streams Biocriter►a Development (NCDWQ 2009) Results will be presented on a site -
by -site basis and will include a list of taxa collected, an enumeration of
Ephemeroptera, Plecoptera, and Tricoptera taxa, and' Biotic Index values.
12 ADAPTIVE MANAGMENT AND REMEDIAL MEASURES
An adaptive management plan will be� developed for each site and for the UMBI in
general. In the, eyent,momtoring results indicate a site will not meet one or more of
its performance standards, remedial actions will be implemented following
notification of the UMBI's USACE project manager -, Adaptive management and
remedial measures are discussed in general below and will be developed further in
the UMBI's Final Mitigation Plan
12.1 Stream Instability
If stream monitoring and /or visual monitoring identify stream stability problems
that worsen or otherwise, threaten other portions, of a mitigation, site,,repairs'will be
made as necessary Persistent problems will be evaluated to determine if design or
construction are contributing factors. Should such systemic problems be identified
and reasonably determined to be unfixable, the IRT may deride to adjust a site's
mitigation credit potential
Restoi ation Systems LLC 47 Cape Fear 02 Umbrella Prospectus
12.2 Vegetation
Vegetation mortality remedial actions may include ,replanting, and, if needed,
corrective measures will be based on a determination of potential reasons for
mortality (e g;, portions of site too wet for planted species). Low vegetation vigor
remedial actions may include but are not limited to deep ripping, replanting (same
or similar species),;m`ow,mg, herbicide application, fertilization, and replantingwith
other species possessing condition - specific tolerance.
12.3 Invasive Species
In the event that .invasive or otherwise undesirable species —as defined in an
appendix to, the "NC,SAM'Users Manual, (NC SFAT 2014) — reasonable efforts will be
made- to eradicate or otherwise control ,growth and distribution of the, species
across the mitigation site, Such- efforts may involve herbicide applications,
mechanical, and /.or hand removal, or prescribed burns.
13 HISTORICALAND ARCHEOLOGICAL INVESTIGATIONS
Field visits were conducted at all Phase I sites during the winter, spring, and
summer of 2014 to ,ascertain the presence of structures or other features that may
be eligible for inclusion on the National Register of Historic Places. No structures
were identified within proposed easement boundaries; however, coordination with
State Historic Preservation Office will occur prior to construction activities to
determine if any significant cultural resources are present
14 Eh DANGERED AND PROTECTED,SPECIES
14.1 Motes Creek, Orphan Creek, and Maple Hill Farm
The United States Fish and Wildlife Service does not list any protected species as
occurring in Alamance County (USFWS 2014) However, six species are designated

14.2 Benton Branch
Two federally protected species are listed as occurring in Caswell County (USFWS
2014)• the James sp►nymussel (Pleurobema collina) and the Roanoke logperch
(Percina rex). Both species are listed as Endangered
14.2.1.1 James,Spinymussel'
This freshwater, mussel 'is limited to the James River ,drainage and the Dan /Mayo
River drainage with the Roanoke Rover basin in Virginia, North Carolina, and West
Virginia This species' range does not include the Benton Branch site, which is
located in the Upper Cape Fear River drainage
14.2.1.2 Roanoke Logperch
In North Carolina, the species is found in the Dan and Mayo rivers, as well as Big
Beaver Island Creek. This species' range does not include the Benton Branch site,
which is located in the Upper Cape Fear River drainage.
14.2.1.3 Preliminary Biological Conclusions
Neither of these species' ranges includes,the site Therefore, this project will have. no
effect on`these federally protected species.
14.3 Chico Branch and Slingshot Creek
Three federally protected species are fisted as occurring in; Rockingham County
(USFWS'2014): the James -spinyinussel (Pleurobema collma), the Roanoke 1'ogperch
(Percma rex), and smooth coneflower '(Echinacea'laevigdta). These species are listed
as Endangered
r
14.3.1.1 James Spinymussel
This freshwater mussel is limited to the James River drainage and the Dan /Mayo
River drainage with the Roanoke River basin i_n, Virginia, North Carolina, and West
Virginia. This species' range does not include the. Chico Branch or Slingshot Creek
site, which,is located'in the Upper Cape Fear River drainage
14.3:1.2 Roanoke Logperch
In North Carolina, the species is found in the Dan and Mayo rivers, as well as Big
Beaver ,Island Creek. This, species' range does not include the Chico Branch or
Slingshot Creek site, which is located in the Upper Cape Fear River drainage
14.3.1.3 Smooth Coneflower
This species grows in calcareous, basic, ,or circumneutral soils on roadsides, clear
cuts, and power line right -of -ways Where there is abundant light and little
herbaceous competition Fire - maintained woodlands also appear to provide
potential habitat for the coneflower- Shading of roadsides by adjacent forest trees
and routine mowing reduce the suitability of roadsides within the study corridor for
this species
Restoration Systerns LLC 49 Cape Fear 02 Umbrella Prospectus
Chico Creek is characterized by disturbed areas that are regularly maintained,
providing little or no opportunity for growing of this species No specimens were
noted during field surveys
Slingshot Creek is characterized by agriculture fields and disturbed forest which
may provide suitable habitat for this species. Detailed surveys for this species may
be required prior to land disturbing activities associated with stream restoration at
this site.
14.3.1.4 Preliminary Biological Conclusions
Neither the James,spineymussel nor the Roanoke logperch have ranges extending to
the site Suitable habitat for the smooth coneflower does not exist at the Chico Creek
site. However, suitable habitat for smooth coneflower may exist at the Slingshot
Creek site and this project may effect on this federally protected species
