Second Annual Report April 2012
1.0 PROJECT OVERVIEW
1.1 History. The 1,297 -acre Hell Swamp /Scott Creek Watershed mitigation site is a
significant component of the compensatory mitigation for future unavoidable impacts to wetlands
and waters as authorized by Section 404 Permit Action ID 200110096 and the Section 401 Water
Quality Certification DWQ #2008 -0868, version 2.0. Hydrogeomorphic monitoring of the stream
valleys was conducted by Baker Engineering. CZR Incorporated (CZR) of Wilmington, NC
monitors hydrology and vegetation of the Hell Swamp site, as well as three other sites (Windley,
Plum's Pit, and Winfield) used as hydrological controls. Restoration activities at Hell Swamp
were authorized by the NC Division of Coastal Management and Coastal Area Management Act
(CAMA) major development permit 83 -09 as well as the NC Division of Land Resources Erosion
and Sediment Control Permits, which were issued for 11 separate phases and further described
in the As Built Report (CZR 2010) and the Baseline and First Annual Report (CZR 2011). Work
occurred from 1 July 2009 until 22 June 2010 and began in areas not subject to CAMA or Section
404 jurisdiction. Planting occurred from February to May 2010, after each phase of restoration
earthwork was completed; planted species and densities are described in CZR 2010.
1.2 Location. The Hell Swamp site is located within the Pamlico Hydrologic Unit
03020104 of the Tar - Pamlico river basin within the Pungo Creek subbasin and is drained by Scott
Creek, Smith Creek, and Broad Creek. The site encompasses almost the entire Scott Creek
watershed and a portion of the watersheds of Smith Creek and Broad Creek. Located on the
southwest side of Seed Tick Neck Road (SR 1714) in Beaufort County, the site is approximately 2
miles east - southeast (straight -line distance) of the town of Yeatesville, Pantego Township, North
Carolina (Figure 1).
1.3 Goals and Performance Criteria. The primary goal of the project is to restore a
self- sustaining functional watershed and wetland /stream complex to allow surface flow to move
through vegetated wetlands before reaching any stream. Mitigation yields are estimated and
performance criteria are described for the project in detail in the Compensatory Mitigation Plan for
Restoration of Hell Swamp /Scott Creek Watershed (CZR 2009). Performance criteria are
summarized in Table 1. Overtime the Hell Swamp site is expected to successfully:
re- establish approximately:
• 19,783 linear feet (LF) of zero and first -order stream, including the
restoration of six riparian headwater systems and three low energy
streams;
• 21 acres of Tar - Pamlico riparian buffer, with additional potential buffer
opportunity if suitable stream segments form in the riparian headwater
systems;
• 58 acres of riparian forested hardwood wetland (headwater forest,
bottomland hardwood forest and riverine swamp forest), with some
additional enhancement potential; and
• 808 acres of non - riverine hardwood flat; and
preserve or rehabilitate:
• 40 acres of non - riverine hardwood flat including a 34 -acre "state or
regionally significant" mature hardwood flat;
• 28 acres of riverine swamp forest /bottomland hardwood forest;
• 18 acres of non - riverine hardwood flat; and
• 200 acres of areas mapped as uplands on the county soil survey.
Hell Swamp /Scott Creek Mitigation Site 1 PCS Phosphate Company, Inc.
Second Annual Report April 2012
An additional 103 acres underlain by hydric soils are included as "potential non - wetland"
areas due to drainage effects from perimeter ditches that must remain open. Approximately 34
acres at the head of the watershed is mature non - riverine wet hardwood forest underlain by Cape
Fear soil (the Windley tract), and will be preserved to help mitigate for impacts to the Bonnerton
non - riverine wet hardwood area. The Windley tract, the Plum's Pit tract (Arapahoe soil), and the
Winfield tract (Augusta, Tomotley, and Roanoke soils) are nearby hardwood forested wetlands at
similar elevations to portions of Hell Swamp and underlain by soil series mapped on Hell Swamp
as shown on the Beaufort County Soil Survey (Kirby 1995). These tracts will be monitored as
hydrologic controls for the restored hydrology of applicable areas at the Hell Swamp site (Figure
1).
2.0 REQUIREMENTS
2.1 Normal Rainfall and Growing Season. A continuous electronic rain gauge is
downloaded once a month and its data are used in conjunction with data from nearby automated
weather stations (e.g., NRCS WETS data from NOAA's site at Belhaven and NOAA's Aurora site
to fill Belhaven data gaps) to determine normal rainfall during the monitoring period. Hell Swamp
data were compared to the WETS range of normal precipitation to determine if Hell Swamp
rainfall was within the normal range. The range of normal precipitation for this report refers to the
30th and 70th percentile thresholds of the probability of having onsite rainfall amounts less than or
higher than those thresholds. The range of normal and the 30 -day rolling total data lines begin on
the last day of each month and the 2011 WETS - Belhaven monthly precipitation total is plotted on
the last day of each month.
Under the 2010 regional guidance from the Corps of Engineers for wetland hydroperiods,
the normal growing season for Beaufort County is 28 February to 6 December or 282 days
(WETS table for Beaufort County first/last freeze date 28 degrees F 50 percent probability) (US
Army Corps of Engineers 2010). At the suggestion of the Corps' Washington regulatory field
office, data collected between 1 February and 28 February provide important information related
to analyses of site hydrology during the early growing season, but are not part of the hydroperiod
calculation for success.
2.2 Hydrology. Figure 2 depicts the locations of hydrology monitoring equipment. To
document surface storage, flow in the restored riparian headwater system, and hydroperiods of
all wetland types on the site, 111 semi - continuous electronic Ecotone water level monitoring wells
(manufactured by RDS) are deployed at a density of approximately 1 well /10 acres in the non -
riparian wetland flat areas. An additional 12 wells within the expected riparian zone and 80 wells
in 40 arrays across the stream valleys measure the hydrology of the riparian stream system and
bottomlands (92 riparian wells). Forty (40) gauges (beta models) to record low flow events were
also installed either within or near each of these stream arrays in early 2011. Each stream valley
array consists of a well on either side of the perceived valley and a flow gauge in the valley where
flow has been evident or seems likely based on the topography of the valley and surrounding
area. The arrays are approximately 500 feet apart (along the long axis) for each valley (at least 3
arrays per 1,000 -foot reach; upstream, center, downstream). The low flow gauges are
programmed to take 72 readings per day and the units are downloaded once a month. For most
gauges, a minimum flow threshold of 0.5 gal /min is used when the data are analyzed and flow
events are tallied. Observations during downloads and stream surveys, rainfall, and geomorphic
position are also part of the analysis and interpretation of the flow gauge data.
Additionally, three electronic wells, each paired with a manual well, are monitored in the
Windley tract (wetland preservation area and control site). Four electronic wells were installed in
October 2010 at Plum's Pit, a nearby hardwood forested wetland at a similar elevation to portions
of Hell Swamp and underlain by one of the soil series found at Hell Swamp. Installation of seven
additional monitoring wells at the Winfield tract (third control area) occurred in July 2011. All well
Hell Swamp /Scott Creek Mitigation Site 2 PCS Phosphate Company, Inc.
Second Annual Report April 2012
locations are also depicted on the Beaufort County Soil Survey sheet 9 (Figure 3) and on LiDAR
(Figures 4A and 4B).
Electronic wells are downloaded once a month and the data (readings every 1.5 hours for
wells) evaluated on an annual basis to document wetland hydroperiods. Wetland hydroperiods
are calculated by counting consecutive days with water level no deeper than 12 inches below the
soil surface during the growing season under normal or below normal rainfall conditions. Data
from the Windley, Plum's Pit, and Winfield sites are used to compare to hydrology at applicable
areas at Hell Swamp. Because of differences in maturity and disturbance characteristics of the
mitigation site, these data will not be used for strict success or performance parameters, only to
confirm local /regional hydrological response to precipitation. Flow gauges are also downloaded
once a month and the data used to calculate duration and frequency of flow events. No control
site for the flow parameter has been identified.
2.3 Vegetation. The second annual survey of the 123 0.22 -acre planted tree and
shrub monitoring plots occurred in October and November 2011 and represents a 2 percent
sample of the restoration area (Figure 2). Smaller (0.017 -acre) planted tree and shrub monitoring
plots were also surveyed at 19 stream arrays to provide an estimate of stem density in the
potential riparian buffer areas. Monitoring for three nuisance species [red maple (Acer rubrum),
sweet gum (Liquidambar styraciflua), and loblolly pine (Pinus taeda)] occurred in 2011 for the first
time as required (Year 2). Nuisance monitoring plots (1 meter square) were established at the
corner opposite the well in all tree plots; all woody stems taller than 1 foot were counted and
identified.
2.4 Hydrogeomorphic Monitoring of Streams and Valleys. The main channel that
flows through the site is named Scott Creek from its headwaters to the downstream extent of the
property at NC Route 99, where the creek flows through a road culvert and eventually discharges
to Pungo Creek, a tributary to the Pungo River. For this report, it is divided into Upper Scott
Creek, which contains the constructed single thread channel and the zero order valley upstream,
and Lower Scott Creek. Several headwater tributaries (UT1 — UT8) were identified that would
have historically drained to Scott Creek or Smith Creek and each is described and shown on
Figures 2 - 4. Two cross sections in the Scott Creek single thread channel stream segment are
measured annually during the monitoring period; the others are measured in the third and fifth
monitoring years.
2.5 Photographic Documentation. Twenty (20) permanent photo point locations
were established at random well locations and five were established near the perimeter of the
restoration area (Figure 2). Photographs were taken in the four cardinal directions as well as an
additional direction to capture as much of the plot as possible unless it was already captured in
the other four photos. Photographs at the fixed -point stations were taken in July 2010 (baseline)
and each subsequent fall during the monitoring period; second annual photographs were taken in
October 2011.
3.0 SUMMARY DATA
3.1 Rainfall. Total rainfall recorded at the Hell Swamp rain gauge for 2011 was
50.54 inches and total rainfall recorded at the PCS Aurora NOAA Station 6 was 46.62 inches.
Total 2011 rainfall recorded at the Belhaven NOAA station is incomplete at the time of this report
so the monthly rainfall totals from PCS Aurora Station 6 were substituted for the Belhaven
monthly gaps. The WETS 30 -year range of normal data shown on Figure 5 is derived from the
latest available data set and comprises the years 1971 -2000. The 30 -day rolling total of Hell
Swamp 2011 rainfall was considered within WETS normal range except for dry periods in mid -
March, mid -May through mid - August, and all of December which were considered below normal.
Mid - February was above normal and Hurricane Irene at the end of August resulted in above
normal rainfall. Rainfall in September and most of October remained above normal (Figure 5).
Hell Swamp /Scott Creek Mitigation Site 3 PCS Phosphate Company, Inc.
Second Annual Report April 2012
Hydroperiods were calculated for the entire growing season without regards to normality of
rainfall and were also calculated for the longest consecutive hydroperiod within the growing
season during normal (and below normal) rainfall only.
The US Drought Monitor (http: / /droughtmonitor.unl.edu) provides a synthesis of multiple
indices and impacts and reflects the consensus of federal and academic scientists on regional
conditions on a weekly basis (updated each Thursday). For North Carolina's Beaufort County,
this monitor reported 28 weeks in 2011 with drought status (11 weeks were classified abnormally
dry, 4.5 weeks were classified as under a moderate drought, and 12.5 weeks were classified as
under a severe drought). During the 41 -week long growing season 16 weeks were classified as
without any drought status. All but four of the weeks with some type of drought status occurred
15 March and 23 August with the arrival of Hurricane Irene.
3.2 Hydrology. The first full year of post- restoration hydrology data for the entire site
was 2011 because construction activities prevented all wells from being installed at the start of
the 2010 growing season. However, wells were installed as soon as construction in an area was
complete, so data were collected during a large portion of the 2010 growing season over most of
the site. Tables depicting 2011 daily well readings and rainfall are included on a companion CD
with this report (hydrology graphs will be provided on a separate CD at a later time).
3.2.1 QA/QC of Well Performance. In 2011, approximately one third of the
Hell Swamp wells were tested for performance. A proportional suite of wells were chosen across
soil types mapped on the site as shown in the Beaufort County Soil Survey (Kirby 1995) and
holes adjacent to each electronic well in the suite were augered to the same depth for
comparison to the electronic well. If water was present in either hole, it was pumped out and
water was added to both holes. Conversely, if no water was present, the same amount of water
was added to both holes. The lapsed time between initial and final measurement ranged from
one hour to 22 hours and depended on soil type and logistics. Of the 36 wells in the suite, 12
were in Arapahoe soils, six were in Portsmouth, five each were in Dragston and Tomotley, four
were in Cape Fear, three were in Roanoke, and one was in Augusta. Of the 36 wells, five test
holes originally showed a difference of 3 or more inches (three were drier and two were wetter
than the screened hole). A second visit to these five sites indicated water level in two of the five
test wells were still greater than 3 inches (one wetter [ Tomotley] and one drier [Arapahoe] than
screened hole). In summary, results of both visits indicate that two test holes were greater than 3
inches different, two were within three inches, five were within 2 inches, 21 were within 1 inch,
and six pair were both dry. Nine of the 36 screened wells contained 0.75 to 1.5 inches of
sediment in the bottom of the screen; however, only one of the nine was wetter than the test hole,
so clogged or plugged screens do not appear to be affecting well performance.
3.2.2 Geomorphic Monitoring, Flow Events and Annual Stream Surveys. Two
cross sections (7 and 8) in the single thread channel of upper Scott Creek were established at
baseline and are measured annually. The second annual measurement occurred in December
2011 and no areas of concern were identified. Appendix A contains the Baker geomorphic report.
Data from the low flow gauges indicate flow occurred at almost all locations at
some point during the year. In some cases, a particular gauge may not have recorded a flow
event, but the gauge just upstream or downstream of the gauge had multiple events. While the
gauges were deployed at logical locations where stream characteristics were perceived to occur
over the course of the restoration and equilibration of the site to the new hydrology, some units
may not be in the best location to capture flow events; as 2011 was a particularly dry year, the
gauges will not be moved but may be redeployed in the future. Excessive rainfall and large flow
volumes from Hurricane Irene may have overcome some of the units as the data appear suspect
after Irene in some units where flow events recorded by the gauge were erratic or values were
repetitive and no longer correlated with rainfall. A summary of the number of flow events and the
number of calendar days with flow for each gauge is shown in Table 4. Tables for each gauge
showing number of flow events and duration and a summary table of observations made during
Hell Swamp /Scott Creek Mitigation Site 4 PCS Phosphate Company, Inc.
Second Annual Report April 2012
downloads or troubleshooting visits are included in Appendix B. Photographs and video of flow at
various locations or evidence of past flow events were taken and noted during both surveys and
selected photos are included in Appendix B. An accompanying CD with video of flow at various
locations is also included with this report.
The first stream survey occurred 27 January 2011 when each headwater valley
was walked to determine the locations for installation of the low flow gauges. In some instances,
the location of the flow gauge was selected slightly upstream or downstream from a given well
array depending on conditions. During the January survey, flow of varying amounts and depths
was noted in almost all the valleys and at almost every gauge location. A second stream survey
was conducted at the end of the year 30 November — 1 December 2011. Active flow was
occurring during the second stream survey at UT8 and Lower Scott Creek; while water was
encountered in other valleys, active flow was not discernible in the other valleys at the time of the
second survey. However, evidence of past flow events was noted during the second stream
survey in UT3, UT6, UT7, UT8, and Upper Scott Creek (sorting, deposition, shallow channel
features, debris /wrack, and braids or meanders). Refer to Appendix B for a summary of the two
surveys, selected photos, and map of documented stream features.
3.2.3 Hydroperiods. The majority of all wells exhibited wetland hydroperiods
regardless of rainfall conditions (Tables 2A and 2B, Figure 6). Many wells had a wetland
hydroperiod in the spring and in the fall. When only the longest consecutive hydroperiod during
normal or below normal rainfall is calculated (i.e. excluding September and October), most wells
still exhibited wetland hydroperiods, although many wetland hydroperiods were reduced (Tables
3A and 3B, Figure 7). The hydroperiods at some locations were shortened by well malfunctions.
The monthly tables depicting 2011 daily noon readings and rainfall which are included with this
report show those gaps. The site was wetter this year than last, even though except for the
above normal rainfall months, the year was relatively dry, as was last year. As evidenced by the
cumulative days shown in the tables, many wells had hydroperiods in addition to the longest
hydroperiod (Tables 2 and 3). Rehydration of the site will continue as the site equilibrates to its
new hydrology, although it may be delayed due to continued regional dryness.
3.2.3.1 Riparian Headwater Systems/Bottomlands. Most of the riparian
wells (49 out of 92) exhibited a wetland hydroperiod greater than 12.5 percent of the growing
season regardless of rainfall conditions (Table 2A, Figure 6). When counting cumulative days
during the growing season, most wells (87) had water levels less than or equal to -12 inches for
more than 6 percent of the growing season and 48 recorded hydroperiods 12.5 percent or
greater. Eight riparian wells did not exhibit a hydroperiod greater than 6 percent which may be
due to the somewhat dry conditions re: precipitation or to a location upslope of the riparian valley
edge.
Since many wells recorded wetland hydroperiods in both the spring and
fall, when well data from above normal rainfall periods (September and October) are excluded,
most wells still exhibited a wetland hydroperiod (Table 3A, Figure 7). Furthermore, even though
many of the hydroperiods were reduced, only two of the wells (UT2 -1 C and UT8-1C) changed
wetness category because of the long duration of the spring wetland hydroperiods. Most wells
also measured water tables shallower than -12 inches between 1 February and 27 February.
3.2.3.2 Non - riparian Hardwood Flat Most (59) of the 111 non - riparian
wells exhibited a wetland hydroperiod for greater than 12.5 to 25 percent of the growing season
regardless of rainfall conditions (Table 2B, Figure 6). Sixteen percent (18) of wells exhibited a
wetland hydroperiod of greater than 12.5 to 75 percent of the growing season and are scattered
across the site (Table 2B, Figure 6). Sixty -nine percent (77) wells exhibited hydroperiods greater
the 12.5 percent of the growing season. Many wells also measured water tables shallower than -
12 inches from 1 February through 27 February.
Hell Swamp /Scott Creek Mitigation Site 5 PCS Phosphate Company, Inc.
Second Annual Report April 2012
Since many wells recorded wetland hydroperiods in both the spring and
fall, when well data from above normal rainfall periods (September and October) are excluded,
most wells still exhibited a wetland hydroperiod (Table 3B, Figure 7). Furthermore, even though
many of the hydroperiods were reduced, none of the wells changed wetness category because of
the long duration of the spring wetland hydroperiod.
In the wetland enhancement area, two wells recorded longer
hydroperiods post- construction (24.8 to 32.3 percent in 2011 for HS17 and HS18) and the longest
2011 hydroperiod at HS2, which did not have pre- restoration data for comparison, was 25.5
percent.
3.2.4 Hydroperiod Comparison to Control Forests.
3.2.4.1 Plum's Pit. Three of the four wells at Plum's Pit recorded
wetland hydroperiods of 32 or 33 percent and the fourth recorded a hydroperiod of 21 percent.
When excluding above normal rainfall months, only one well had a wetland hydroperiod. All
wells, except one also measured water tables shallower than -12 inches from 1 February through
27 February (Figures 6 and 7).
3.2.4.2 Windley. The three wells in the Windley tract (Refl - Ref3)
exhibited hydroperiods of 26 or 32 percent of the growing season) regardless of rainfall
conditions. However, during normal or below normal rainfall, the wetland hydroperiods were
reduced. All wells also measured water tables shallower than -12 inches from 1 February
through 27 February. Two of the wells did not measure many other days during the year outside
the continuous hydroperiod with a shallow water table, but the well with the longest hydroperiod
measured another 29 days with water shallower than -12 inches during the growing season
(Figures 6 and 7).
3.2.4.3 Winfield. The seven wells in the Winfield tract were installed on
27 July 2011 after an agreement with the owner was reached to use the site as a hydrological
control during the monitoring period; therefore, early spring hydroperiods were not recorded if
they occurred. Three of the wells did not exhibit a wetland hydroperiod, two others were >6
percent but less than 12.5 percent. One well exhibited a 32 percent hydroperiod. None of the
seven wells exhibited a wetland hydroperiod during normal rainfall (Figures 6 and 7).
3.3 Vegetation. Additional treatment to control the invasive common reed
(Phragmites australis) occurred in September /October 2011 in the forested section of lower Scott
Creek with application of Habitat @. Control of common reed in lower UT6 appears effective from
previous treatment, but this and other areas will be assessed in June /July 2012 to determine
whether subsequent treatment is necessary.
Results of the Year 2 nuisance monitoring indicate that when all three species are
combined, they represent 47.8 percent of the 180 stems counted in the 123 plots. When counted
individually, loblolly pine was 31.7 percent, red maple was 11 percent, and sweet gum was 5
percent. Loblolly pine is a problem in three plots (HS2, HS122, and HS124) where 48 of the 57
total loblolly pines were counted. Plot HS2 is located in a wetland area that was a young pine
forest prior to restoration with abundant seed source available to sprout. The other two problem
plots are located near the southeastern boundary of the site, east of UT8, adjacent to mature
loblolly pines along the property edge which also provide abundant seed source. This issue will
be discussed with the Corps of Engineers and a course of action determined.
By use of only the number of planted stems that were unquestionably alive in the
monitoring plots, the most conservative estimate of survival is presented. Many stems appeared
dead or questionable, but based on prior monitoring experience, a stem needs to appear dead (or
not be found) for two sampling events before it can be confidently counted as dead. Appendix C
Hell Swamp /Scott Creek Mitigation Site 6 PCS Phosphate Company, Inc.
Second Annual Report April 2012
contains the number of stems that were alive in each plot for the baseline sampling event and for
the fall 2011 survey.
3.3.1 Riparian Buffer. Overall survival of trees that were unquestionable alive
in the 19 riparian buffer plots from baseline (mid- summer 2010) to fall 2011 was 84 percent, with
a corresponding density of 725 trees per acre (Table 5). If trees with uncertain survival status
(stem appeared dead but could not be confirmed) are included with trees that were definitely
alive, survival increases to 92 percent and a density of 794 trees per acre. Red bay (Persea
palustris) and water tupelo (Nyssa aquatica) had the lowest survival (38 and 40 percent,
respectively and same as last year) when excluding the uncertain stems (Table 5). Twelve (12)
of the 20 tree species had 80 percent or greater survival, with seven of the 12 at 100 percent
survival. If uncertain stems are added, 12 species reach 100 percent.
Only four shrub species represented by only a few stems were found in the
riparian buffer plots; likely due to the overall low density of shrubs across the site and the small
size of the buffer plot. Overall survival of shrubs from baseline (mid- summer 2010) measurement
to fall 2011 was 60 percent for stems that were unquestionably alive with a corresponding density
of 19 shrubs per acre (Table 5). If shrubs with uncertain survival status (stem appeared dead for
the current sampling event but will not be confirmed until next fall) are included with shrubs that
were definitely alive (less conservative estimate of survival), survival increases to 90 percent and
a density of 28 shrubs per acre. All shrub survival percentages and densities are lower than last
year. Buttonbush (Cephalanthus occidentalis, 1 stem) and winterberry (Ilex verticillata, 2 stems)
had the lowest survival (0 percent) and swamp doghobble (Leucothoe racemosa, 1 stem) had the
highest survival (100 percent) when excluding the uncertain stems. If uncertain stems are
combined with those unquestionably alive, survival of the three species is 100 percent. The
fourth species, Virginia willow (Itea virginica) is represented by five stems that were
unquestionably alive but its survival is at 83 percent. Buttonbush and winterberry survival is
much higher in the hardwood flat monitoring plots.
Density in the potential riparian buffer areas for all trees and shrubs combined
after fall 2011 survey was 747 stems per acre for all species unquestionably alive and 822 stems
per acre if species with alive and uncertain survival status are combined. The current density is
much higher than the 320 stems required for success, so even though densities and survivals are
lower than last year, it is anticipated that the densities will remain above the minimum required
amount.
3.3.2 Riparian Areas /Bottomlands. Within the 12 plots located in
riparian /bottomland areas, overall survival of trees from baseline (mid- summer 2010) to fall 2011
survey was 78 percent for stems unquestionable alive, with a corresponding density of 290 stems
per acre (Table 6). If trees with uncertain survival status (stem appeared dead but could not be
confirmed) are included with trees that were definitely alive, survival increases to 88 percent and
a density of 327 trees per acre. Survival of red bay, sweet bay (Magnolia virginiana), unidentified
oaks, and water tupelo is less than 50 percent and less than 15 percent for the two bays.
Survival of eight of the 18 tree species is >_90 percent and two of these eight are 100 percent.
When the uncertain stems are included, survival of nine species is >_90 percent, six of which are
100 percent.
Overall survival of shrubs from baseline (mid- summer 2010) to fall 2011 survey
was 53 percent for stems that were unquestionably alive, with a corresponding density of 6
shrubs per acre (Table 6). If shrubs with uncertain survival status (stem appeared dead for the
current sampling event but could not be confirmed and will be confirmed at the next event) are
included with shrubs that were definitely alive (less conservative estimate of survival), survival
increases to 63 percent and a density of 9 shrubs per acre.
When all 92 riparian plots are combined (Table 5 and Table 6), density of all
unquestionably alive stems in the riparian areas after the 2011 fall survey is 346 stems per acre
Hell Swamp /Scott Creek Mitigation Site 7 PCS Phosphate Company, Inc.
Second Annual Report April 2012
and survival is 73 percent. When the uncertain stems are included, density increases to 390
stems per acre and 83 percent survival. Both density estimates are higher than the 260 stems
required for successful restoration.
3.3.3 Non - riparian Hardwood Flat. Overall survival of trees unquestionably
alive in the 111 plots representing the non - riparian hardwood flat area from baseline (mid-
summer 2010) to fall 2011 was 91 percent, with a corresponding density of 380 trees per acre
(Table 7). If trees with uncertain survival status (stem appeared dead but could not be confirmed)
are included with trees that were definitely alive, survival increases to 96 percent and a density of
401 trees per acre. Sourwood (Oxydendron arboreum), red bay, and unidentified oak species
had the lowest survival (0, 14, and 19 percent, respectively) when excluding the uncertain stems,
and 15 species had 90 percent or greater survival (Table 7). When adding the uncertain stems,
nine of the 25 tree species had 100 percent survival and 20 had 90 percent or greater survival.
Overall survival of shrubs from baseline (mid- summer 2010) to fall 2011 survey
was 86 percent for stems that were unquestionably alive, with a corresponding density of 13
shrubs per acre (Table 7). If shrubs with uncertain survival status (stem appeared dead for the
current sampling event but could not be confirmed and will be confirmed at the next event) are
included with shrubs that were definitely alive (less conservative estimate of survival), survival
increases to 94 percent and a density of 14 shrubs per acre. Swamp rose (Rosa palustris) had
the lowest survival when excluding the uncertain stems (0 percent) but was represented by only 1
stem in all plots (Table 7). Swamp doghobble and possumhaw viburnum (Viburnum nudum) had
the highest survival (100 percent) when excluding uncertain stems and five other shrub species
had >90 percent survival. If uncertain stems are combined with those unquestionably alive,
survival of five of the ten species is 100 percent and all species survival is greater than 89
percent.
Density in the non - riparian hardwood flat areas for all trees and shrubs combined
after the 2011 survey was 394 stems per acre for all species unquestionably alive (88 percent
survival), and 417 stems per acre if species with alive and uncertain survival status are combined
(93 percent survival) (Table 7). Both density estimates are higher than the required 260 stems.
3.5 Photographic Documentation. Although the planted stems rarely show above
the vegetation yet, a few photos representative of 2011 conditions are paired with baseline
photos at the same location in this report for comparison (Appendix D). More are available upon
request.
4.0 SUMMARY
According to WETS rainfall estimates, dry periods in mid - March, mid -May through mid - August,
and all of December were considered below normal. Hurricane Irene at the end of August
resulted in above normal rainfall and September and most of October remained above normal
due to large rain events.
Post - restoration wetland hydrology and flow monitoring for success officially began January 2011.
Most wells on the entire Hell Swamp site, including on the nine headwater valley systems,
recorded wetland hydroperiods during periods of normal or below normal rainfall. Wells at Plum's
Pit and Windley reference forests also recorded similar wetland hydroperiods. Wells at Winfield
reference forest recorded no wetland hydroperiod or shorter hydroperiods than the Hell Swamp
and the other control forests, possibly as a result of not being installed until mid - summer, after the
wet winter /spring. Some evidence of flow (braided patterns, channel formation, flowing water)
has been seen in some areas of most of the stream valley systems, including the single- thread
channel.

Second Annual Report April 2012
Overall survival of trees unquestionably alive in the 19 riparian buffer plots from baseline (mid-
summer 2010) to fall 2011 survey was 84 percent, with a corresponding density of 725 trees per
acre. Overall survival of shrubs in the potential riparian buffer areas from baseline (mid- summer
2010) to fall 2011 survey was 60 percent for stems that were unquestionably alive, with a
corresponding density of 19 shrubs per acre. Survival density in the potential riparian buffer
areas for all trees and shrubs combined after the 2011 survey was 747 stems per acre for all
species unquestionably alive and 822 stems per acre if species with alive and uncertain survival
status are combined. Overall survival of trees unquestionably alive in the other 12 riparian plots
from baseline (mid- summer 2010) to fall 2011 survey was 78 percent, with a corresponding
density of 290 trees per acre. Overall survival of shrubs in the riparian plots from baseline (mid-
summer 2010) to fall 2011 survey was 53 percent for stems that were unquestionably alive, with a
corresponding density of 6 shrubs per acre. Survival density in the 12 riparian plots for all trees
and shrubs combined after the 2011 survey was 297 stems per acre for all species
unquestionably alive and 338 stems per acre if species with alive and uncertain survival status
are combined. When all riparian data are combined, density is 346 stems per acre and survival is
73 percent for stems unquestionably alive.
Overall survival of trees in the 111 non - riparian hardwood flat plots from baseline (mid- summer
2010) survey to fall 2011 was 91 percent, with a corresponding density of 380 trees per acre;
when uncertain stems are included survival increases to 96 percent and density is 401 stems
trees per acre. Overall survival of shrubs in the hardwood flat areas from baseline (mid- summer
2010) measurement to fall 2011 survey was 86 percent for stems that were unquestionably alive,
with a corresponding density of 13 shrubs per acre; when uncertain stems are included, survival
increases to 94 percetn and density is 14 stems per acre. Survival density in the non - riparian
hardwood flat areas for all trees and shrubs combined after the 2011 survey was 394 stems per
acre for all species unquestionably alive and 417 stems per acre if species with alive and
uncertain survival status are combined.
Overall survival of all stems unquestionably alive at Hell Swamp is 86 percent with 388 stems per
acre; with the uncertain stems added survival increases to 92 percent and 414 stems per acre.
All planted areas are currently well above density success requirements for each type of
mitigation.

2011 CROSS SECTION MEASUREMENTS IN
SINGLE THREAD RESTORED CHANNEL OF UPPER SCOTT CREEK
BAKER ENGINEERING 2011 HELL SWAMP CROSS SECTION MEASUREMENT
1.1 Geomorphic Monitoring
For monitoring stream success criteria, 34 permanent cross - sections were installed following construction
m2010. In accordance with the Hell Swamp Mitigation Plan (July 2009), three cross - sections were
established per 1,000 foot reach of stream /valley restoration. The permanent cross - sections are used to
monitor channel formation and scour overtime. For the riparian headwater systems (no defined channel
construction), these cross - sections were measured for the as -built report and will also be measured at
Years 3 and 5 if channel features form. For the Scott Creek single thread channel stream restoration
segment, the cross sections were measured for the as -built report and then annually during the monitoring
period.
1.1.1 Geomorphic Success Criteria
Valleys should remain stable with minimum changes through the monitoring period; however,
these cross - sections may show minor changes in flow patterns as valleys develop.
1. 1.2 Results and Discussion
Two permanent cross - sections (7 and 8) are established in the Scott Creek single thread channel.
Year 2 monitoring data from these two cross - sections were collected in December 2011. Cross -
sectional data collected during this monitoring event, were compared to the as -built baseline data
collected in 2010. Approximate locations of the two cross sections and 2011 cross - sectional
graphs from each of the monitored cross - sections are included on the following page.
Permanent cross - section 7 is located across a riffle at station 47 +66 on Scott Creek. According to
the Year 2 survey data, the channel features in riffle cross - section 7 have remained very stable
since as -built conditions. No significant areas of concern regarding the channel along this cross -
section were noted following Year 2 monitoring. The survey data did record some changes in the
floodplain along cross - section 7. The floodplain changes observed are attributed to flood
deposition, soil settling, vegetation maturity, and slight differences in survey point location. The
floodplain observations noted are expected with newly constructed restoration sites, where some
minor adjustments are common.
Permanent cross - section 8 is located across a pool at station 52 +81 on Scott Creek. According to
the Year 2 survey data, the channel features in pool cross - section 8 have remained stable since as-
built conditions. The Year 2 data show that cross - section 8 has experienced some minor
deposition within the pool area of the channel, but this is common for pools in restored
meandering channels, and will likely vary from year to year depending upon the flow frequency
and magnitude. The survey data also recorded some changes in the floodplain along cross -
section 8. The channel and floodplain changes observed along cross - section 8 are attributed to
flood deposition, soil settling, vegetation maturity, and slight difference in survey point location.
The pool and floodplain observations noted are expected with newly constructed restoration sites,
where some minor adjustments are common.
According to the Year 2 survey data, cross sections 7 and 8 have experienced some slight
adjustments and settling since as -built conditions. The adjustments observed in the monitored
cross - sections are minor and are not considered to demonstrate signs of instability. No areas of
appreciable scour have been observed within the restored channel.
1.1.3 Areas of Concern
No areas of concern have been identified for the restored headwater prongs.

Hell Swamp /Scott Creek Mitigation Site
Second Annual Report PCS Phosphate Company, Inc.
Appendix B B -41 April 2012
2011 STREAM SURVEYS OF HELL SWAMP HEADWATER VALLEY SYSTEMS
On 27 January 2011, all the headwater valleys at Hell Swamp were walked to determine
the best locations for the low flow gauge to be installed. At the same time, active flow or
evidence of past flow was also documented with photographs and video. Active flow of various
strengths and in various water depths was observed in all valleys with the exception of UT4 and
UT5. On 30 November and 1 December 2011, the headwater valleys and tributaries were
surveyed for evidence of flow events and formation of any channel features. Each system was
walked from the downstream end to its upstream end. Physical features noted included bed and
bank, sediment transport and /or scour, debris wrack, matted vegetation in orientation of
downstream flow, or lack of vegetation. When evidence of channel formation was longer than 10
feet the perceived channel was walked with GPS and points collected along the axis and at the
beginning and end of the feature. Until the planted trees and shrubs reach enough height to
shade the valleys, development of dense herbaceous vegetation will continue to occur in many
areas. This herbaceous layer can attenuate flow events and reduce velocity below the point of
scour and can also obscure other incipient channel formation features. Photos of certain stream
features are included after the text descriptions below.
Lower Scott Creek. This segment includes the most downstream reach of the stream
portion of project (fill of the channelized section of old Scott Creek) and ends at the first stream
crossing constructed at the location of the old Scott Creek culvert under the farm road. Actively
flowing during the January survey, the lower end of the filled ditch continued to exhibit stream
features by the second survey including bed and bank formation, a meandering profile, sediment
transport, lack of vegetation, and flowing water. A 121 -foot long channel has formed in this
segment and continues upstream beside the old ditch spoil and then enters into the vegetated
Scott Creek swamp forest and becomes indistinct. No other stream features were found in the
old filled Scott Creek channel nor in the vegetated swamp forest of Scott Creek. No low flow
gauges or stream arrays are located in the lower Scott Creek filled ditch or vegetated swamp
forest.
Constructed Single Thread Channel of Upper Scott Creek. Most of channel is
choked with vegetation and no flow was evident at the time of the second survey although there
was water in the channel. The riffle areas of the channel appear less vegetated in the upper
reach than in the lower.
Upper Scott Creek. This segment begins above the constructed single thread portion of
Scott Creek. Matted vegetation oriented in the direction of flow was evident for 45 feet of the
valley just above the confluence with the single thread channel. At array 5 there was evidence of
sheet flow and just upstream of constructed stream crossing vegetation is oriented in the direction
of flow but no flow was discerned in 3 to 4 inches of water. ATV wakes have oriented the
vegetation on either side of the constructed crossing. A barely distinct channel has formed on the
south side of the valley about half the distance to array 6 and another feature in the valley invert
has vegetation oriented in direction of flow but no strong evidence of flow. There are many ruts
and ATV tracks up the valley and across the valley. Between array 8 and array 9, a 131 -foot
channel has formed with little to no vegetation and some sorting; the channel almost disappears
in some spots. A second channel of 108 feet has formed above array 9, although its features are
faint. A 36 -foot channel has formed as an offshoot of the 108 -foot feature. Although small, bed
and bank were evident as was scour in the shorter channel. Between array 9 and array 10 two
additional channels have formed, one of 181 feet and one of 69.5 feet.
UT8. Most of this valley displayed no evidence of flow or channel formation. Water is
being held in the valley but the amount of algae in the water indicates long periods of standing
water and lack of flow. A discernible channel 55 feet in length has formed just upstream of the
constructed stream crossing on UT8 and lack of vegetation and little scour were features noted in
this short channel during the survey. Upstream of array 6, the valley is very rutted.

Appendix B
UT7. This valley had more water in its upper portion than its lower at the time of the
survey, but all the stream features were confined to the lower half. Between array 1 and array 2,
a 97 -foot channel has formed with meander, shallow bed and bank, no vegetation in channel, and
signs of sediment transport.
UT6. At the confluence of UT6 with lower Scott Creek, a 46 -foot long channel has
formed with evidence of sorting and flowing water at the time of the survey. Beyond this channel
there is an extensive section of standing water until just downstream of the confluence of UT7
(nuisance vegetation removal in this area left large deep ruts which were not able to be smoothed
into a headwater valley shape during stream construction because the ground remained too wet
to work). Near array 5, the perceived valley bottom was wetter than the surrounding valley, the
vegetation became sparse, and the valley appeared to split into two although no strong evidence
of bed and bank were noted. In one area downstream of array 6, very shallow bed and bank
appeared to have been formed along the southern edge of the valley. The upper end of UT6
valley is vegetated but while no water was evident at the time of the survey in the upper valley,
there were numerous areas where dead plant stems were imbricated in the direction of flow, and
scattered small wrack lines were evident.
UT5. Natural channel development appears to be inhibited, or at least interrupted, by a
large tracked vehicle rut up the long axis of the valley and the entire lower valley is dissected by
ruts across the long axis.
UT4. Although the feature was holding water in some places, no flow features were
noted in this valley. There were some very short meanders noted in a few places but they were
filled with vegetation and there were many ruts perpendicular to the long axis.
UT3. The lower end of this valley south of the old farm road appears too rutted across
the long axis for natural stream development. An ATV trail runs up the apparent lowest part of
the valley to the second flow gauge and there are numerous cross axis ruts. Two channels have
formed in the UT3 valley, an 84 -foot segment in the vicinity of array 3 and a 69 -foot segment near
the end of array 4. Both segments have a narrow flow way devoid of vegetation, some scour,
some very shallow bed and bank, stem orientation to flow direction, and some small wrack piles.
UT2. Although there was little vegetation at array 1, there was no evidence of flow at the
time of the survey. The valley is densely rutted and heavily vegetated with herbaceous species in
the top portion of the valley.
UT1. Not as rutted in the upper portion as other valleys but some interruption of potential
development by ruts. Dense juncus and grass clumps made it difficult to find flowways; some
small flow paths 5 to 10 feet long but not GPSd. Valley is holding water but no evidence of flow
at the time of survey.
