1.0. Project Summary
1.1. Project Goals & Objectives
The Morgan Creek Floodplain Restoration Site (DMS # 258) is located on the Mason Farm Biological
Reserve (MFBR) in the Jordan Lake watershed (Haw River, Cape Fear River, USGS HUC # 03030002-
060080). In the 1940's a soil berm (artificial levee) was constructed along the southwest bank of
Morgan Creek to reduce flooding frequency, and ditches were excavated to further drain the floodplain
and facilitate farming. The berm, drainage ditches, and land -use activities have degraded the former
bottomland wetlands on the site. This restoration project is designed to restore natural floodplain
hydrology by constructing five rock -stabilized openings through the berm to increase floodwater access
from Morgan Creek, and by replanting native trees and shrubs on poorly vegetated or weed -dominated
areas on the floodplain to restore a natural Piedmont Bottomland Forest community. The project
includes 14.37 acres of wetland restoration, 5.61 acres of wetland preservation, and 3200 linear feet of
riparian buffer preservation along the south bank of Morgan Creek. Specific goals and objectives for
the Morgan Creek Floodplain Restoration project are identified below:
Project Goals:
1. Facilitate regular flooding of the Morgan Creek floodplain behind the berm;
2. Promote attenuation of sediment and nutrients on the flood plain;
3. Reduce downstream flooding by creating additional storm water detention;
4. Reduce erosion by limiting flooding shear stress on Morgan Creek banks ;
5. Restore more natural hydrology to 14.37 acres of impacted wetlands;
6. Preserve 5.61 acres of existing forested wetlands;
7. Re-establish a natural plant community through plantings and invasive species control;
8. Preserve 3200 linear feet of riparian buffer on the south bank of Morgan Creek.
Project Objectives:
1. Create five stable openings in the existing artificial berm to allow flood waters to access the
floodplain with the conservation easement area;
2. Plant 14.37 acres of bottomland hardwood wetlands with desirable native trees and shrubs;
3. Demonstrate jurisdictional hydrology in 14.37 acres of restored wetland by measuring groundwater
using RDS continuous recording groundwater gauges;
4. Preserve the entire Site through means of a conservation easement or deed restrictions in perpetuity.
1.2. Project Success Criteria
Post -construction monitoring (2011 to 2015) will evaluate the project's success in restoring flood
hydrology through the berm openings, groundwater hydrology in wetlands, and reestablishment of
native bottomland forest vegetation. No stream channel work was conducted, and no channel
morphology monitoring or stream stability success criteria are included.

Orange/Durham County: Cape Fear HUC 03030002 Mogensen Mitigation Inc / R.J. Goldstein Assoc.

Restoration of wetland hydrology is evaluated using specific soil saturation criteria for two different soil
units delineated by The Catena Group in 2008, based on field analysis of redoximorphic features. Soil
Unit #1, which occupies most of the fallow field in the east -central portion of the project easement, is
expected to achieve saturation within 12 inches of the ground surface for at least 12.5% of the growing
season (27 days). GW monitoring gauges # 1, 2, 4, 5 and 6 are located in Soil Unit #1. Soil Unit #2 lies
to the west of Soil Unit #1 and includes the western part of the fallow field and adjacent forested land.
Hydrology in Soil Unit #2 is expected to achieve saturation within 12 inches of the ground surface for at
least 5% of the growing season (11 days), and includes GW monitoring gauges # 3, 9, A, B, and C. The
climatic growing season in Chapel Hill is from March 28 to Nov 3 (227 days).
Restoration of floodplain function is evaluated using crest stage gauges (granular cork type) installed at
each of the five berm openings. These manual gauge data are supplemented with stream stage data
recorded at USGS stream gauge #02097517 located 1,600 feet upstream of the project site. On average,
the berm openings are expected to convey overbank flows from Morgan Creek 2 to 3 times per year.
Five 10 x 10 meter CVS vegetation plots were established, marked and monitored in the planted wetland
restoration area following the CVS-EEP Level 2 Vegetation Monitoring Protocol. The success criteria
requires a minimum survival rate of 320 native woody stems per acre in MY -3, 288 native woody stems
per acre in MY -4, and 260 stems/per acre in MY -5. Areas with low density of native woody stems
(planted plus volunteers) and/or exotic invasive species problem areas are identified and mapped in
accordance with thresholds specified in the current EEP monitoring guidance document.
1.3. Project Setting & Pre -Restoration Conditions
The Morgan Creek Floodplain Restoration Site (DMS # 258) is located on the Mason Farm Biological
Reserve (MFBR) which straddles the Orange/Durham county line, in the Jordan Lake watershed (USGS
HUC # 03030002-060080). The project site is within the Durham -Sanford Triassic Basin, an area with
broad floodplains due to ancient geologic rifting. Floodplain elevations on the project site are 240 to
245 feet (NAVD83). MFBR is owned by the University of North Carolina at Chapel Hill and is currently
used for ecological research and teaching, but prior to the 1980's the floodplain portion of MFBR was
used for agriculture. About 1940 an earthen berm (artificial levee) 3,800 feet long and 6 ft high was
constructed along the southwest bank of Morgan Creek, 30 to 60 feet from the top of the creek bank.
The berm was constructed to reduce flooding frequency, and floodplain ditches were excavated to
further drain the area and facilitate farming. These actions significantly degraded wetland hydrology,
hydric soil indicators, and native wetland vegetation.
Prior to project construction, approximately 17.5 acres within the project area showed relict
redoximorphic features or other evidence of historically supporting wetland hydrology. A 7 -acre
remnant of intact wetland remains on the easternmost portion of the project site. This area was not
effectively dewatered by the berm and ditches, apparently due to beaver dams, log jams, and other
factors causing backwater flooding effects around the southeastern end of the berm. The drained
wetland areas suitable for restoration include 12 acres of old field scrub and 5 acres of plantation forest.
Both the field/scrub and forest areas contain a mix of native and exotic species, described in the
Restoration Plan (Ward Consulting Engineers, 2008).

Orange/Durham County: Cape Fear HUC 03030002 Mogensen Mitigation Inc / R.J. Goldstein Assoc.

Morgan Creek adjacent to MFBR has a drainage basin area of 41 square miles. Normal baseflow water
surface elevation in the creek is typically 2.5 to 3.5 ft below the adjacent floodplain on the project site.
Based on USGS gauge records and pre -construction surveys by the project designers, stream flows
exceeding 1,000 cfs begin overtopping the banks of Morgan Creek and filling the depressional areas
behind the natural levees along the stream banks. Flows above 1,300 cfs (calculated bankfull flow
presumably flooded the project area prior to berm construction in the 1940's. The 6 -ft berm height was
built to contain the 10 -year storm event, and would have required flows above 3,400 cfs to flood the
project area prior to 2010 when the berm openings were constructed.
1.4. Project Components & Mitigation Assets
The project includes five rock -stabilized trapezoidal openings (gaps) excavated through the berm. Each
gap is 15 feet wide at the base (at the existing floodplain elevation) and roughly 50 feet wide at the top
of the berm. Mitigation assets include 14.37 acres of wetland restoration (1:1 ratio) and 5.61 acres of
wetland preservation (5:1 ratio), generating a total of 15.49 wetland mitigation units. The project
conservation easement contains 31.5 acres, including 3200 linear feet of riparian buffer preservation
along the south bank of Morgan Creek (Jordan Lake watershed). No mitigation credit is sought for the
buffer preservation component.
1.5. Project Design Approach
The Morgan Creek Floodplain (Mason Farm) restoration project was designed by Ward Consulting
Engineers (2008) with assistance from The Catena Group, and constructed in 2010. The five berm gaps
are located along a 1,400 foot long berm segment in the northwestern portion of the project area. Gap
locations were selected to coincide with segments of stable stream bank, adequate space between the
bank and the berm, and low areas on the creek side of the berm (behind the natural levee) to facilitate
flow passage most easily. The berm gap bed elevations range from 244.1 ft (upper gap) to 242.4 ft
(lower gap) and are generally 2.5 to 3.5 ft above normal baseflow elevation in Morgan Creek. Flow
through the berm gaps is expected when stage at the USGS stream gauge upstream reaches 7.8 ft.
The berm gap openings were modeled as lateral openings in the HEC -RAS computer model, and
discharges were generated from each opening to reflect the volume of water applied to the fields. A
second HEC -RAS model was then generated in the floodplain beyond the berm using the peak
discharges flowing through the openings to predict the extent of flooding within the MFBR. This
second model approximated maximum storm water levels within the existing parking lot and the
frequency and duration of flooding in Big Oak Woods (BOW) natural area south of the project area.
Flooding into BOW was controlled in order to avoid potential adverse ecological impacts of increased
flooding depth, frequency, or duration.
The wetland restoration planting plan was developed from lists of native species found in nearby natural
floodplain wetlands along Morgan Creek. The Catena Group conducted post -construction monitoring
from 2010 to 2012, after which Mogensen Mitigation, Inc. (MMI) conducted the remainder of
monitoring from fall 2013 through 2015.

1.6. Current Conditions & Performance Summary
MMI conducted the MY5 monitoring work during Sep -Dec 2015; monitoring methods and reporting
were done following the EEP/DMS Monitoring Report Template, Feb 2014 version.
Vegetation:
CVS vegetation plot data were collected in September 2014. The five plots had 6, 5, 7, 5, and 0
surviving planted stems; only plot #3 exceeded the 260 stems/acre success criterion based on planted
stems alone (Tables 6-7). However, four of the five plots have large numbers of volunteer native trees
(Diospyros, Fraxinus, Liquidambar, and Ulmus) and exceed the success criterion when volunteers are
included. The failing plot (#1) missed the success criterion by only one stem. Plots #1 and #5 (no
surviving planted stems) are overgrown with dense grasses and herbaceous weeds that impede survival
of tree seedlings. Total native woody stem densities (planted plus volunteers) range from 243 to 1,133
stems per acre, and average density for all five plots is 769 stems per acre, nearly three times the success
criterion. Native woody stem density in the remainder of the planted areas appears adequate; no low-
density area greater than of 0.2 acre was observed.
Exotic invasive weeds are common throughout the project site in both the field/scrub areas and forested
areas. Common invasives observed on the floodplain include Japanese stiltgrass (Microstegium
vimineum), Multiflora rose (Rosa multiflora), Japanese honesuckle (Lonicera japonica), Dahurian
buckthorn (Rhamnus davurica), Chinese privet (Ligustrum sinense), White mulberry (Morus alba),
Porcelain -berry (Ampelopsis brevipedunculata), Fescue (Festuca spp), and Sericea lespedeza (Lespedeza
cuneata). Two areas with concentrations of "High Concern" invasive species (mainly Rosa) totaling
0.62 acre are included in Figure 2 and Table 5. Elsewhere, "High Concern" invasives are at relatively
low densities and/or primarily occurring as groundcover beneath tall shrubs and saplings, and do not
appear to be threatening re-establishment of a forest community. Japanese stiltgrass (Low/Moderate
Concern) is abundant throughout most of the field/scrub portion of the project and some wooded areas.
Stiltgrass combined with other dense herbs is impeding planted tree survival in plot #5 (no planted stems)
and volunteer recruitment in plot #1 (no volunteers).
Additional invasive species observed along the Morgan Creek streambank and berm include Kudzu
(Pueraria montana) and Paper mulberry (Broussonetia papyrifera), but these areas are currently forested
and the exotic plants are not threatening to project success.
Hydrology:
Nine of the ten groundwater wells met their respective wetland hydrology success criteria in 2015 (Table
9). Only well #4 did not meet its criterion, missing the goal by only 2 days). Over the five year
monitoring period (2011 to 2015), four of the five wells in Soil Unit #1 met their 27 -day saturation
criterion during 3 or more years. Of the five wells in Soil Unit #2 (11 -day saturation criterion),well #3
succeeded during only 1 year, well #9 succeeded every year, and the new wells A, B, C all succeeded
during their one year of monitoring. Daily precipitation data for 2015 were compiled from CoCoRaHS
gauge # NC -DH -33 located at Meadowmont about one mile northeast of the project site.

Orange/Durham County: Cape Fear HUC 03030002 Mogensen Mitigation Inc / R.J. Goldstein Assoc.

The berm gaps appear to have conveyed flow from Morgan Creek into the floodplain during at least five
storm events in 2015 (Mar 5, Apr 19, Oct 2, Nov 9, and Nov 19) as documented in Table 8 and the
stream gauge data included in Appendix D support files. October 2 had the highest recorded stage at the
USGS gauge, and cork levels recorded on the berm gap crest gauges were probably deposited on this
date. Peak water depths through the berm gaps in 2015 based on crest gauge measurements ranged from
0.7 to 2.7 feet. The berm gap erosion problems reported in 2013-2014 were repaired in 2015, and all
five openings are in good condition as of Dec 2015.
Easement Condition:
The Morgan Creek Floodplain conservation easement boundary is not fenced, but is marked by signage
on posts at regular intervals along the western and southern boundaries. Existing trails on the MFBR
property including the project site are frequently used for walking and wildlife watching, but no
evidence of any damage by users was noted. There is no livestock kept on or adjacent to the project site.
Some grazing damage by deer and other wild herbivores was noted during CVS plot monitoring.
2.0. Project Monitoring Methods
2.1. Vegetation Methods
Five 10 x 10 meter square CVS vegetation plots were established in 2011 and monitored according to
the CVS-EEP Level 2 Vegetation Monitoring Protocol for Recording Vegetation 4.2 (Lee et al 2008).
Each plot corner is marked with 1" PVC and/or steel conduit pipe and survey flagging, and plot corners
are mapped using a Trimble sub -meter GPS unit. Planted trees and shrubs are measured during Sep -Oct
each year, native volunteer stems are counted, and invasive species abundances are described. CVS plot
locations are mapped in Figure 2, and vegetation plot data are provided in Tables 6-7. Plant
identification manuals used are Radford (1968) and Weakley (2015). Each CVS plot was digitally
photographed, usually from the 0,0 plot corner unless dense vegetation or other constraints required
photographing from a different corner.
2.2. Hydrology Methods
Nine RDS Ecotone groundwater monitoring gauges were installed between Jun 2010 and Aug 2011
following Technical Note HY lA-3.1 (USACE 1993). Groundwater Gauge #s 1, 2, 3, 4 and 5 are within
the fallow field planted portion of the project, and Gauges #6 and #9 are in areas with existing forest
canopy. Gauge #7 was installed in 2010 a reference wetland on the Morgan Creek floodplain upstream
of the project area, but was moved in 2012 to a nearby location due to beaver activity at the original site.
This well at the new location is referred to as Gauge #10 in the 2012 to 2014 reports. It was damaged
and removed in 2014 e s. Gauge #8 was installed in a wetland in the Big Woods area of MFBR south of
the project area, and was not monitored after 2012. Three additional gauges designated A, B, and C
were installed by DMS in the fall of 2014 in the forest plantation area of the project, near gauge #9.

Orange/Durham County: Cape Fear HUC 03030002 Mogensen Mitigation Inc / R.J. Goldstein Assoc.

Two different success criteria for wetland hydrology are based on soil morphology differences described
and mapped by The Catena Group (Ward Consulting Engineers, 2008). Groundwater Gauge #s 1, 2, 4, 5,
and 6 are within Soil Unit #1, where saturation for 12.5% of the growing season is required. Gauge #s 3,
9, A, B, and C are within Soil Unit #2, where saturation for 5% of the growing season is required.
Gauge data and success attainment are provided in Table 9 and Appendix D support files.
Flow events through the berm gaps are evaluated using manual crest stage gages (granular cork type)
installed at each of the five berm gaps. Cork levels on the stake inside the gauge are measured at least
twice a year, and the gauges are cleaned and reset at each visit. Stage data from USGS stream gauge
#02097517 located 1,600 feet upstream of the project site are used for dating the peak events recorded
by the crest gauges and documenting other dates when peak flows are likely to have flooded through the
berm gaps.

Areas
Note: Planted stem survival was poor in some areas, but native volunteer trees have filled in, and no planted area of .25 acre or larger
presently has low density of native woody stems.
1 = Enter the planted acreage within the easement. This number is calculated as the easement acreage minus any existing mature tree stands that
were not subject to supplemental planting of the understory, the channel acreage, crossings or any other elements not directly planted as part of the
project effort.
2 = The acreage within the easement boundaries.
3 = Encroachment may occur within or outside of planted areas and will therefore be calculated against the overall easement acreage. In the event
d into items 1, 2 or 3 in the table and is the result of encroachment, the associated acreage should be tallied in the relevant
item i.e., item 1,2 or 3) as well as a parallel tally in item 5.
4 = Invasives may occur in or out of planted areas, but still within the easement and will therefore be calculated against the overall easement
acreage. Invasives of concern/interest are listed below. The list of high concern spcies are those with the potential to directly outcompete native
youngq'' woody stems in the short-term (e.g. monitoring period or shortly thereafter) or affect the community structure for existing, more established
tree/s-hrub stands over timeframes that are slightly longer (e. . 1-2 decades). The low/moderate concern group are those species that generally do
not have this capacity over the timeframes discussed an, tfierefore are not expected to be mapped with reqularit , but can be mapped if in, the
judgqement of the observer their coverage, density or distribution is suppressinq the viabilityy density, or growtFi of planted woody stems. decisions
as fo whether remediation will be needed are based on the integration of risk factors b ESP such as species present, their coverage, distribution
relative to native biomass, and the practicality, of treatment. For example, even modest amounts of Kudzu or Japanese Knotweed early in the
protects history will warrant control, but potentially large coverages of Microstegium in the herb layer will not Ilkley trigger control because of the
limited capacities to impact tree/shrub layers within the timeframes discussed and the potential impacts of treating extensive amounts of ground
cover. Those species with the watch list" designator in gray shade are of interest as well, but have yet to be observed across the state with any
frequency. ,Those in red italics are of particular interest given their extreme risk/threat level for mapping as points where isolated specimens are
found, particularly ealry in a projects monitoring history. However, areas of discreet, dense patches will of course be mappe was polygons. The
symbology scheme below was one that was found to be helpful for symbolzing Invasives polygons, particulalr for situations where the conditon for
an area is somewhere between isolated specimens and dense, discreet patches, In any case, the point or po�ygon/area feature can be symbolized
to describe things like high or.low concern and species can be listed as a map inset, in legend items if the number of species are limited or in the
narrative section of the executive summary.
