Project Setting and Background Summary
The Key Branch stream and wetland restoration project is located in Anson County, North Carolina The 118 -acre project site encompasses 87 1 acres of restored wetlands and
approximately 6,183 linear feet of restored stream channel within the Brown Creek watershed of the Yadkin River basin Prior to restoration, extensive site disturbances between
1938 and 1993 resulted in the conversion of bottomland hardwood wetlands to agricultural fields Approximately 45 percent of the property had been logged and cleared by 1956
Key Branch was ditched and relocated during the 1960s Brown Creek was channehzed and rerouted to its current location during the 1970s By 1984, most of the lateral ditches
were extended half the length of the site During the 1990s, the westernmost lateral ditches were extended to intersect Key Branch while the easternmost lateral ditches were
extended to the southern boundary Restoration constriction occurred during the fall of 2003 and included the filling of lateral ditches to limit offsite drainage, the removal of an
impoundment berm to site elevation in order to increase discharge onto the site, the breaching of the levee along Brown Creek to restore connectivity between the stream and
floodplam, and the restoration of Key Branch throughout the site to reestablish stream- wetland interface Construction was immediately followed by re- vegetation of 70 2 acres of
the site in February, 2004, to reestablish the bottomland hardwood forest community Subsequent replanting of the project area occurred in February, 2005
Goals and Obiectives
Restored functions of the system will include
- Nutrient removal/transformation
- Flood flow alteration
- Aquatic species diversity /abundance
- Wildlife species diversity /abundance
These functions will be restored through
- Restoration/preservation of bottomland hardwood/swamp hardwood communities
- Restoration of floodplain/wetland interfaces
- Restoration of natural stream channels and drainage patterns
- Reestablishment of wildlife habitat
Success Criteria
- Wetland Under normal precipitation Restored wetlands must be saturated within 12 inches from the soil surface by groundwater consecutively for at least 12 5
percent (31 days) of the growing season and inundation must occur in at least half of the monitoring years
- Vegetation At least 320 planted stems per acre must be surviving after the third growing season The required survival critenon will decrease by 10 percent per year
after the third year of vegetation monitoring for the next two years (i a for minimum requirement of 288 stems per acre in year 4, and 260 stems per acre in year 5)
- Streams Restored stream channels must show vertical and honzontal stability with respect to as -built conditions by exhibiting no significant changes to the
dimension, pattern, profile, and bed matenal during the monitoring period

Table 5 Vegetation Species Planted Across the Restoiation Site
Please note that while the initial site planting included approximately 47,800 bottomland
hardwood species over 70 2 acres at an average density of 680 stems per acre However, in 2004,
vegetation monitoring of 8 plots within the wetland restoration area, six months after the initial
site planting, revealed that the surviving 44 percent of the original planted stems consisted of
green ash (40 stems, 30 3 %), overcup oak (31 stems, 23 5 %), riverbirch (24 stems, 18 2 %),
willow oak (18 stems 13 6 %), swamp chestnut oak (17 stems, 12 9 %), and water oak (2 stems,

Table 6 Vegetation History Stems Per Acre of the Planted Stock
Please note that stem per acre vegetation density recorded in Table 6 includes both the original
planted stems and volunteers of the same species as the planted stock Additional volunteers
noted but were not included in stem pe► acre calculations, these species included box elder (Ater
negundo), red maple (Ater rubrum), common hackberry (Celtts laevigata), common persimmon
(Dtospyros virgemana), swamp holly (Ilex decidua), sweetgum (Ltguidambar styracii lua), laurel
oak (Quercus lauri(olca), pin oak (Quercuv palustris), black oak (Quer(us velutcna), American
elderberry (Sambucus canadensis), winged elm ( Ulmus alata), and slippery elm ( Ulmus rubra)
As stated to the success cntena, site re- vegetation is considered successful if 320 planted stems
per acre survive through the third growing season The required survival criterion decreases by
10 percent per year after the third year The Key Branch mitigation site was planted at an average
density of 680 stems per acre in November of 2003 High mortality rates in the first year after the
initial site planting resulted in a re- planting in February of 2005 Vegetation monitoring in

Page 13 of 26

September of 2006 revealed a mean density for all vegetation monitoring plots at 527 stems per
acre, exceeding the minimum requirement by 237 stems per acre Again, in 2007, the mean
density for all vegetation monitoring plots satisfied the success criteria at 836 stems per acre,
exceeding the minimum requirement by 576 stems pet acre For questions regarding stem per
acre calculations, please refer to the explanation offered below Table 6
Vegetation monitoring from 2008 through 2011, found that the vegetation density steadily
increased from year to year due to successful recruitment of volunteers In 2011, it was noted
that each plot exhibited good diversity Between 5 and 9 species were reported in each plot and a
total of 15 different species were noted across all plots Many of the trees exhibited heights in
excess of 8 to 10 feet Based on the findings of the vegetation monitoring, the Key Branch
mitigation site re- vegetation is successful
Wetland Hydrology
As stated to the success criteria, hydrology is considered successfully restored if restored
wetlands are saturated to within 12 inches of the soil surface consecutively for a hydropenod of
more than 12 5 percent of the growing season, and inundation occurs in at least half of all
monitoring years Data synthesized from the groundwater monitoring data presented_ in Table 7 is
shown below
Gauges highlighted in yellow to Table 7 lie outside the delineated wetlands All other gauges are
located within the delineated wetlands
The delineation was based on the following parameters conelated with the gauges that exhibited
the higher percent hydroperod
Pnmary indicator
• Presence of 20 percent or more distinct or prominent redox concentrations within top 5 inches
of the soil surface including few (2 percent) oxidized pore linings
Secondary indicator
• Common (5 percent) or more Manganese masses within top 5 inches of the soil surface
In addition, we utilized the F19 indicator from the document, Field Indicators of Hydric Soils in
the US, as another source of wetland documentation

Please note that mean monthly precipitation for 1893 -2012 was downloaded from USHCN
station 315771, Monroe, NC (34.9797, - 80.5233). Please note that the Relative Precip. column
represents the average level of precipitation received from 2004 through 2012 relative to the
average precipitation received from 1893 through 2012. Thenumbers in the Relative Precip.
column were calculated by subtracting 1893 - 2012 average precipitation from 2004 - 2012
average precipitation for both monthly and yearly values.

The Key Branch site is a large stream and wetland complex restored in the Brown Branch
floodplain. The drainage area for that section of Brown Branch is approximately 50 square
miles. Riparian vegetation is showing excellent growth and vigor after the extended monitoring
period. The site's vegetation recovered well after the drought in the early years of the project. In
addition, the project fills in a vegetated corridor that was missing for many years in the stream
system.
Overall, the stream survey data indicates a stable channel with very little lateral or vertical
movement (see Figures 5.1 -5.12 and Figure 6). The stream gauge registered seven bankfull
events during the 2011 monitoring year (see Table 3) further demonstrating stream stability. The
wetland hydrology data with delineation criteria mentioned in the above section strongly
supports the wetland mitigation units proposed.
Special Note: the stream footage Dronosed is 6.183 linear feet. In the as- built. DOT needed to
curtail building the last 763 linear feet and tie into the old conveyance given the wet conditions.
We would like to propose this footage for EII credit since planting was done in that area and the
rest of the proiect contributes to the floodplain enhancement. In addition, Brown Branch proper
was not offered as preservation credit formerly, but does have a 50 foot riparian buffer on both
sides. The Brown Branch reach that borders the property comprises 3.488 linear feet. At a 7:1
preservation ratio, this would yield 498 smus. Combined with the 763 foot reach at 2.5:1 (305
smus). would eaual 803 smus. we offer this proposal instead of undertaking a nermit
modification.
EEP recommends closeout of the Key Branch site with 6,183 stream mitigation units and 82.62
riparian wetland mitigation units.

Contingencies
Beavers
Although the restored stream reach meets criteria for success, beaver are abundant in the area
and have persistently re- colonized the Key Branch mitigation site after prior removal efforts
Beaver are active with dams above and below the Site as well as within the Site boundaries
Dams we►e removed most recently in 2010 but were reestablished in 2011

APPENDIX A — WATERSHED PLANNING SUMMARY
Brown Creek: 03040104061030
This is a newly designated TLW with approximately 28% of its stream length identified as impaired
for Aquatic Life and Overall according to 2006 DWQ 303(d) data. Increased impervious surface,
some agricultural practices, permitted dischargers and hydromodification from an impoundment
could be contributing to low dissolved oxygen violations and impaired biological integrity in this
watershed. Portions of the Town of Ansonville are within this watershed and there are almost 20
animal operations contained here as well. In addition, the watershed includes Wildlife Resource
Commission priority area, has land already under conservation, including portions of the Pee Dee
National Wildlife Refuge managed by U.S. Fish and Wildlife Service, and also land designated as
Significant Natural Heritage Area. There are several Natural Heritage Element Occurrences as well
as a large amount of forest and wetlands. Existing watershed improvement efforts taking place in this
watershed will allow for the opportunity to continue implementing projects here and would
cumulatively result in ecological uplift.

mowing, destruction, removal, or other damage of any vegetation, disposal or storage of any
debris, trash, garbage, or other waste material, except as may be authorized by the mitigation
plan, or subsequent modifications that are approved by the Corps of Engineers, Wilmington
District In addition, the permittee shall take no action, whether on or off the mitigation property,
which will adversely impact the wetlands or streams on the mitigation property, except as
specifically authorized by this permit, or subsequent modifications that are approved by the
Corps of Engineers, Wilmington District
h The permittee shall mitigate for 21 acres of unavoidable impacts to nvenne
wetlands and 6 7 acres of non - nvenne wetlands within the Yadkin River Basin (Hydrologic
Catalog Units 03040104 & 03040201) by restoring, at a minimum, 55 4 acres of nvenne wetlands
at the Key Branch Mitigation Site as described in the report entitled "Key Branch Wetland
Mitigation Plan" dated August 24, 2001 In addition, the following stipulations shall apply to this
mitigation site
i To meet the success criteria, the monitoring data must show that for each
normal precipitation year within the monitoring period, the site exhibits saturation within the
upper 12 inches of the soil surface for a minimum of 12 5% or 31 days, or greater consecutive
day duration during the growing season and inundation must occur 5 out of 10 years or 50% of
the years monitored, at a minimum frequency Baseline hydrologic date shall be obtained from
the reference site, which can be used to support the mitigation site's hydrology success WETS
tables for Moore County will be utilized as appropriate to determine normal precipitation years
li The mitigation site will be planted with native vegetation that represents
both woody (trees and shrubs) and herbaceous species Species selection will be based on a
survey of the vegetation from the reference sites Survival of woody species planted at the
mitigation site should be at least 320 trees/acre through year three A ten percent mortality rate
will be accepted in year four (288 trees /acre) and another ten percent in year five resulting in a
required survival rate of 260 trees /acre through year five
iii Vegetation monitoring must begin in the spring just after leaf -out
Permanent randomly located sample plots shall be established at the mitigation site Plot size
should be based on established standards for sampling vegetation planted at the target densities,
usually 0 05 acre (50 -foot X 50 -foot) A minimum of eight vegetation sampling plots shall be
established at the site After the first year of monitoring, the sample size (number of plots) shall
be checked by use of statistical methods used to identify adequate sample size and if necessary
adjusted The planted tree stock shall be marked by use of tree marking paint and/or tree tags for
identification and sampling Plants that have colonized the sample plot should be identified and
noted in the monitoring report but not used in the planted vegetation monitoring calculations
Plant recruitment should be calculated as a separate item and corrective measures may need to be
taken if the volunteers are undesirable or are jeopardizing the survival of the planted stock The
measurement of planted stock survival using stem density will be acceptable provided that only
planted stock is counted In addition, in order to get an indication of health and vigor of the
