Subject: RES Pasquotank 05 UMBI White Hat (SAW- 2018-0207) Monitoring Year 1 Report Submittal

Mr. Tugwell:

On behalf of Environmental Banc & Exchange, LLC, a wholly owned subsidiary of Resource Environmental Solutions (RES), I
am pleased to submit the RES Pasquotank 05 UMBI White Hat MY1 Monitoring Report. Monitoring activities were completed
November 14-16, 2023.
Cross sections are all stable and remain similar to conditions at as-built. All 18 of the fixed vegetation plots and 10 of the 12
random vegetation plots passed the interim success criteria of 320 stems per acre. The stage recorder on reach DC1-A
recorded 2 bankfull events, and the one on DC1-B recorded 3 bankfull events. Two of the 10 groundwater wells passed the
12% wetland hydrology success criteria. Low hydroperiods were likely displayed due to monitoring beginning in April after
the start of the growing season, and due to precipitation levels being low in May-August and in the month of October.
Hydroperiods are expected to improve during MY2.
Planned maintenance includes a supplemental planting on and around the spoil mounds, treating invasive Chinese privet,
and re-seeding a few areas with low herbaceous cover. The locations of all maintenance activities can be seen on the MY1
CCPV.

Comments from As-Built Credit Release:
1. Wetland H currently has 2 permanent veg plots; recommend changing one of the plots to a random transect or
capturing the area with a random transect periodically during monitoring.
As of MY1 both permanent veg plots remain within Wetland H (veg plots 2 and 5). Additionally, Random veg plot 2
was taken within Wetland H this year. This area will be resampled with a random veg plot again in a future
monitoring year.
2. Add a photo point on the floodplain erosion at the outlet of Swale B and a photo of the Swale B looking towards
the ESP.
A photo point has been added to the CCPV and the photo for MY1 can be found in Appendix B labeled as “Photo
Point 3 – Swale B Pool (11/15/2023)”.
3. Add a photo point with a view of the riffle adjacent to VP1, which had an excessive amount of rock in the channel.
A photo point has been added to the CCPV and the photo for MY1 can be found in Appendix B labeled as “Photo
Point 1 – Riffle (8/3/2023)”.
4. Add a random plot in Wetland Area H during a future monitoring year.
Random veg plot 2 was taken within Wetland Area H this year. This area will be resampled with a random veg plot
again in a future monitoring year.

Upon approval of this monitoring report, RES is requesting a 10% stream credit release (735.173 SMUs) and a 10% wetland
credit release (0.809 SMUs). A credit breakdown is shown on the following page. Please see the enclosed credit release
schedule, updated credit ledger, and MY1 monitoring report.
Thank you for all your time and consideration. Please contact me at 336-705-3041 or [e-mail] if you have any

1 PROJECT SUMMARY
1.1 Project Location and Description
The White Hat Stream and Wetland Mitigation Project (“Project”) is located within Perquimans
County, approximately nine miles east of Hertford, NC. The Project lies within the Pasquotank
River Basin, North Carolina Department of Water Resources (“NCDWR”) sub-basin 03-01-52
and United States Geological Survey (“USGS”) 14-digit hydrologic unit code (“HUC”)
03010205060020 (Figure 1). The Project is designed to help meet compensatory mitigation
requirements for stream and wetland impacts in the HUC 03010205.

The Project is comprised of a 75.99-acre conservation easement contained within six parcels
and a 23.60-acre draft perpetual flowage easement extending west toward Godfreys Lane. The
Project involves the restoration and enhancement of Deep Creek, a named stream forming to
the west of the easement boundary flowing east through the Project to the Little River,
eventually draining to the Albemarle Sound. Within the conservation easement, the stream
channel is divided into three reaches, DC1-A, DC1-B, and DC1-C and is surrounded by a system
of interconnected jurisdictional wetlands. The Project restored 5,254 linear feet (LF) and
enhanced 1,541 LF of stream as well as restored 3.461 acres, enhanced 13.891 acres, and
preserved 3.429 acres of wetlands that will ultimately provide water quality benefits and
ecosystem uplift for the Project’s 1,859-acre drainage area.

The aquatic resources associated with the Project had been highly manipulated and degraded
over time due to agricultural practices. Project stream reaches, specifically DC1-A, DC1-B, and
DC1-C of Deep Creek, had historically been dredged and straightened, leading to channels
with limited habitat and poor hydraulic function. Dredging and straightening had also
adversely impacted the hydrology of the surrounding wetlands and caused some areas to lose
jurisdiction. Also, networks of surface ditches draining toward the main channel further altered
the natural hydrology of the stream-wetland complex. Much of the forested area surrounding
the conservation easement had been cleared for row crop production resulting in narrow to
absent riparian areas. Current and historical pine planting and harvesting operations have led
to a monoculture in upstream areas along the channel and limited the natural vegetative
diversity within the riparian areas. Therefore, the Project presented a great opportunity to
address stressors identified within the watershed while also providing tremendous additional
uplift to a degraded stream-wetland floodplain system.
1.2 Project Goals and Objectives
Through the comprehensive analysis of the Project’s maximum functional uplift using the
Stream Functions Pyramid Framework, specific, attainable goals and objectives are realized by
the Project. These goals clearly address the stream and landscape manipulations that have
altered natural pattern, hydrology, habitat, and riparian buffers, as well as address agricultural
impacts such as nonpoint source runoff and hydrologic modification that have degraded water
quality in the watershed. Ultimately, these goals promote long-term resilience to the inevitable
White Hat Stream and 4 MY1 Report
Wetland Mitigation Site January 2024
issues that were identified as major watershed stressors in the 2009 Pasquotank River RBRP.
The Project addresses these stressors and supports RBRP goals.

The Project goals were:

· Re-establish the natural position, pattern, and function of the stream-wetland complex;
· Improve water transport from watershed to the channel in a non-erosive manner;
· Improve water quality within the restored channel reaches and downstream
watercourses by reducing sediment and nutrient loads;
· Improve flood flow attenuation on site and downstream by allowing for overbank flows
and connection to the active floodplain;
· Improve instream habitat;
· Restore and enhance native floodplain vegetation;
· Improve ecological processes by reducing water temperature, improving terrestrial
and aquatic habitat, and restoring a native plant community; and
· Restore and enhance riparian wetlands.

The Project objectives that addressed these goals were:

· Design and reconstruct stream channels to be relocated within the historic low
position, sized to convey design flows that will maintain a stable dimension, profile,
and planform;
· Add in-stream structures and bank stabilization measures to protect restored and
enhanced streams;
· Install habitat features such as brush toes, brush bed sills, riffles, wood material, and
pools of varying depths to restored and enhanced streams;
· Reduce bank height ratios and increase entrenchment ratios;
· Increase forested riparian buffers to approximately 100 feet on both sides of the
channel along the project reaches with a hardwood riparian plant community;
· Treat exotic invasive species;
· Re-establish and enhance riparian wetlands by raising stream bed elevations, plugging
surface
· ditches, and planting native wetland plant species;
· Establish a permanent conservation easement on the Project; and
· Establish a permanent perpetual flowage easement upstream of the Project.

1.3 Project Success Criteria
The success criteria for the Project follows the 2016 USACE Wilmington District Stream and
Wetland Compensatory Mitigation Update and subsequent agency guidance. Specific success
criteria components are presented below.
White Hat Stream and 5 MY1 Report
Wetland Mitigation Site January 2024
1.3.1 Stream Restoration Success Criteria
Four bankfull flow events must be documented within the seven-year monitoring period. The
bankfull events must occur in separate years. Otherwise, the stream monitoring will continue
until four bankfull events have been documented in separate years.

There should be little change in cross sections from as-built. If changes do take place, they
should be evaluated to determine if they represent a movement toward a less stable condition
(for example down-cutting or erosion) or are minor changes that represent an increase in
stability (for example settling, vegetative changes, deposition along the banks, or decrease in
width/depth ratio). Cross sections shall be classified using the Rosgen stream classification
method, and all monitored cross sections should fall within the quantitative parameters
defined for channels of the design stream type. Bank height ratio shall not exceed 1.2, and the
entrenchment ratio shall be no less than 2.2 within restored riffle cross sections.

Digital images will be used to subjectively evaluate channel aggradation or degradation, bank
erosion, success of riparian vegetation, and effectiveness of erosion control measures.
Longitudinal images should not indicate the development of bars within the channel or an
excessive increase in channel depth. Lateral images should not indicate excessive erosion or
continuing degradation of the banks over time. A series of images over time should indicate
successional maturation of riparian vegetation.
1.3.2 Wetland Success Criteria
The Natural Resources Conservation Service (NRCS) has a current WETs table (1911-2020) for
Pasquotank County upon which to base a normal rainfall amount and average growing season.
Data for Perquimans County was not available; therefore, the closest comparable data station
was determined to be the WETS station in Elizabeth City, NC. This station determines the
growing season to be 258 days long, extending from March 14 to November 27, and is based
on a daily minimum temperature greater than 28 degrees Fahrenheit occurring in five of ten
years.

Based upon field observation across the site, the NRCS mapping units show a good correlation
to actual site conditions in areas of the site. Mitigation guidance for soils in the Coastal Plain
suggests a hydroperiod for Roanoke, Perquimans, and Pasquotank soil series of 9 to 12
percent of the growing season; and 12-16 percent for Chowan soil series. Soil in the
surrounding upland soil map units and immediately adjacent to the floodplain are anticipated
to have shorter hydroperiods. Small depressional areas underlain by a clayey subsoil may
exhibit longer hydroperiods exceeding 16 percent. Therefore, hydrology success criterion for
the Project is to restore the water table so that it will remain continuously within 12 inches of
the soil surface for at least 12 percent of the growing season (approximately 31 days) at each
groundwater gauge location. Due to the current drainage and permeable soils, it may take at
least a year for the site to become completely saturated and reach the target hydroperiod.

White Hat Stream and 6 MY1 Report
Wetland Mitigation Site January 2024
1.3.3 Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the
Project will follow IRT Guidance. The interim measures of vegetative success for the Project
will be the survival of at least 320 planted three-year old trees per acre at the end of Year 3,
260 five-year old trees at 7 feet in height at the end of Year 5, and the final vegetative success
criteria will be 210 trees per acre with an average height of 10 feet at the end of Year 7.
Volunteer trees will be counted, identified to species, and included in the yearly monitoring
reports. In order for a volunteer tree to count towards success criteria, it must be a species on
the approved planting list and be present for at least two growing seasons. Moreover, any
single species can only account for up to 50 percent of the required number of stems within
any vegetation plot. Any stems in excess of 50 percent will be shown in the monitoring table
but will not be used to demonstrate success.
1.4 Project Components
Through stream restoration and enhancement, the Project presents 6,795 LF of stream, that
generated 6,281.333 base Warm Stream Mitigation Units (“SMU”) (Table 1). By incorporating
wider buffers, the total adjusted SMUs for the Project amount to 7,351.733. Additionally, the
Project presents 20.781 acres of wetland re-establishment, enhancement, and preservation,
that generated 8.434 Riparian Wetland Mitigation Units (“WMU”) (Table 1).

Both SMUs and WMUs totals have changed from those proposed in the Mitigation Plan due
to an easement change detailed in section 1.6. Total SMUs decreased from 7,363.663 to
7,351.733, and WMUs decreased from 8.470 to 8.434. These changes are detailed in Table 1.
Additionally, the changes have been accounted for in the Credit Release Schedule included
with this report.

areas and wetland credit areas do not overlap.
1.5 Stream and Wetland Design/Approach
The detailed treatment plan and design approach are as follows:
1.5.1 Streams

Reach DC1-A & B
An offline restoration approach was used for this reach to address channelization and loss of
habitat. Priority Level I Restoration was conducted on Reach DC1-A, which entailed raising the
channel bed and restoring a stable single thread channel through the existing floodplain. The
existing channels were backfilled with material excavated from onsite to the elevation of the
floodplain in areas adjacent to the new channel. Woody debris was installed throughout the
reach to improve aquatic habitat. Woody debris was added in the channel in the form of typical
riffles (all riffles will be a mix of 75% woody material / 25% native substrate), brush bed sills,
and brush toes. Channel banks were live-staked, and a minimum 100-foot buffer was
established and planted with native riparian vegetation, but buffers exceed 100 feet in many
areas. Invasive species will be treated.

Multiple drainage ditches ran through the easement and tied directly to the existing channel.
The ditches that use to confluence with DC1-A flowed through existing wetlands with
dimensions and slopes indicative of stormwater treatment swales and were therefore tied
directly into DC1-A. The ditches that used to confluence with DC1-B did not exhibit these
treatment characteristics and were therefore directed into treatment swales before they outlet
into DC1-B or existing jurisdictional wetlands. The existing hunting impoundment, south of
DC1-A, was graded during construction.

Reach DC1-C
An Enhancement I approach was conducted on this reach to address lack of appropriate
channel pattern, channel dimension, limited habitat, and limited connection to the left
overbank area. Enhancement activities promoted appropriate channel pattern, channel
dimension, habitat, and encouraged the formation of a natural stream and wetland complex
in the low gradient floodplain of Deep Creek. Reference section 6.1.2.1.2 for a detailed analysis
of the hydraulic changes provided by this enhancement. Enhancement activities included:

White Hat Stream and 8 MY1 Report
Wetland Mitigation Site January 2024
- Installation of 12 single wing deflectors to promote channel pattern, flow diversity,
appropriate channel dimension and overbank flows.
- Removal of the existing road on the left bank. Removal included the excavation of 50
percent of road material to provide connection from the channel to the low areas of
the left bank wetland. Excavated material was deposited on the remaining areas of the
existing road to form hummocks and promote floodplain flow and habitat diversity.
- Riparian planting along the top of the single wing defectors and the created
hummocks.

1.5.2 Wetlands
The White Hat Project offers a total ecosystem restoration that revitalizes a highly manipulated
floodplain forest community. As such, the wetland restoration and enhancement are closely
tied to the stream restoration. Wetland restoration re-established hydrology and hydrophytic
vegetation to previously non-wetland areas that exhibit hydric soil indicators and drained
hydrology, while enhancement areas improve hydrology or vegetation in already jurisdictional
wetland areas. The Project provides 8.434 Riparian WMUs through a combination of wetland
re-establishment, enhancement, and preservation. Notably, areas generating wetland credit
are either within the 50-foot stream buffer area of stream channels or are wholly outside of
the non-standard buffer width areas generating additional stream credit (greater than 150
feet). Therefore, wide buffer areas utilized for additional stream credit and wetland credit areas
do not overlap (Figure 9 & Figure 11).

Re-establishment
Wetland re-establishment with a credit ratio of 1:1 occurred for areas 50 feet out from the
stream channel top of bank where jurisdictional wetlands do not exist and includes areas of
existing stream channel footprint, spoil, farm path, and drained areas. These re-establishment
areas connect the existing jurisdictional wetlands (WJ, WH, WK, WE, and WD), resulting in a
contiguous riparian wetland corridor. The system of interconnected re-established wetlands
on the western side of the easement break, is collectively referred to as “WR-1” (Wetland Re-
establishment 1) (Figure 2). Most of these areas incorporate the footprint of the existing,
excavated Deep Creek channel that was backfilled and graded to match the existing floodplain
elevations in association with the stream restoration. However, there are other small areas
within WR-1 that contain hydric soils but lack sufficient wetland hydrology and a lowered
water table due to the altered landscape and drainage modifications, including the relocated
and incised Deep Creek, presence of highly permeable soils, and the location of drainage
ditches intercepting groundwater discharges onto the floodplain. Moving east across the
easement break, “WR-2” (Wetland Re-establishment 2) was restored 50 feet out from the
proposed channel. This system of wetlands borders jurisdictional wetlands WF and WG. As
mentioned above, the hydrologic restoration of this area was directly related to the stream
restoration and re-vegetation activities. Reconstructing Deep Creek (specifically reach DC1-A
and DC1-B), with an appropriately sized channel back within the low of the existing floodplain
and filling the incised, abandoned channel, will raise the local groundwater elevation that will
White Hat Stream and 9 MY1 Report
Wetland Mitigation Site January 2024
allow frequent flooding. Also, the re-established wetland area were planted with bare root
hardwood trees representative of a Coastal Plain Small Stream Swamp community. Due to the
high organic matter of existing soil and existing natural surface topography, ripping was not
required; however, where construction equipment was utilized, limited surface roughening
was necessary due to the structure of high organic soil that was destroyed by equipment.

In order to document hydrology and establish baseline conditions for wetland re-
establishment area WR-1 and WR-2, one groundwater hydrology well was installed within the
area, near the easement break. In addition, one well was installed within existing, jurisdictional
wetland, just outside of the western-most Project boundary, within the perpetual flowage
easement to serve as a reference and document less disturbed hydrologic conditions.
Unfortunately, this well was damaged sometime between its installation in May 2019 and
present day and therefore can no longer be used as a reference. Limited data was collected
from it to establish a baseline reference. The other well was installed in May 2019 with an
automatic pressure transducer within the well, which recorded data twice per day. Data from
these wells was presented in the Final Mitigation Plan.

Enhancement (Medium)
Wetland enhancement with a credit ratio of 3:1 occurred for the jurisdictional wetlands WJ,
WH, WK, WG, WF, WE and WD in areas 50 feet and >150 feet out from the stream channel
top of bank. These wetlands are naturally fed by groundwater; however, anthropogenic
disturbance from agricultural production (clearing), ditching, and planted pine monocultures
created unfavorable conditions for regeneration of woody wetland vegetation. Therefore, the
primary approach to enhance these wetlands was to plant native bare root trees, characteristic
of a Coastal Plain Small Stream Swamp in order to establish a wetland hardwood forest
community. By reconstructing and enhancing Deep Creek, with an appropriately sized channel
back within the low of the existing floodplain, and plugging and filling the incised, abandoned
channel, the local groundwater elevation will rise and more frequent flooding will occur,
ultimately improving hydrology to the entire system.

Preservation
Wetland preservation with a credit ratio of 10:1 occurred for the remaining jurisdictional
wetland areas within WG and WF that was not directly enhanced by stream restoration efforts.
These areas lie outside of the non-standard buffer width areas (greater than 150 feet) as well
as directly south of DC1-C, and will remain forested and protected in perpetuity.

1.6 Construction and As-Built Conditions

An easement revision was required for this project to provide adequate space for farm
equipment to utilize the existing farm crossing. This was discussed with USACE Todd Tugwell
via email on 1/20/2023. The easement revision resulted in minor changes to the stream and
White Hat Stream and 10 MY1 Report
Wetland Mitigation Site January 2024
wetland crediting which are accounted for in this report. An overview of the easement revision
was included in the As-Built Report.

Stream construction and planting were completed in March 2023. The White Hat Site was built
to design plans and guidelines with one major change; Swale D was redesigned to keep several
mature trees. The record drawings were included in Appendix E of the As-Built report.

There were no major changes in the planting plan from the Final Mitigation Plan. The 14
proposed tree species were planted on March 13 and 14, 2023. Due to wet conditions and
high-water levels during planting, Swales A and B were only planted around the edges to
prevent stem mortality.

Minor monitoring device location changes were made during as-built installation; however,
the quantities remained as proposed in the Final Mitigation Plan.

1.7 Year 1 Monitoring Performance (MY1)
The White Hat baseline monitoring activities were performed on November 14-16, 2023. All
MY1 data is present below and in the appendices. The Project is on track to meeting
vegetation, stream, and wetland interim success criteria.
1.7.1 Vegetation
Monitoring of 18 fixed vegetation plots and 12 random vegetation plots was completed on
November 16th, 2023. Vegetation data is in Appendix C, associated photos are in Appendix
B, and plot locations are in Appendix B. MY1 monitoring data indicates that all fixed plots
and 10 of the 12 random vegetation plots are exceeding the interim success criteria of 320
planted stems per acre. The area represented by random veg plot 12 only failed by 1 tree. RES
expects this area to pass in future monitoring years when stems are taller and detection is
better. If this area continues to fail RES will perform a supplemental planting. The area
represented by random veg plot 10 is approximately 1.18 acres on and around the stockpiles
where stem mortality is high. A supplemental planting of 1-gallon container trees will occur
during MY2 in these areas. Species chosen for the planting will be from the approved planting
list. Planted stem densities ranged from 162 to 890 planted stems per acre with a mean of
567 planted stems per acre across all plots. A total of 13 planted species were documented
within the plots. Four volunteer species were noted during monitoring, with Ulmus americana
(American elm) being the most common volunteer. The average stem height in the plots was
1.54 feet.

Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous
vegetation has become established since as-built. Some stream banks and one small area
within the easement have low herbaceous cover. These areas will be reseeded during MY2
with the same seeding mix sown during construction. Chinese privet (Ligustrum sinense) was
noted in low densities within the downstream portion of the easement. Approximately 4.1
White Hat Stream and 11 MY1 Report
Wetland Mitigation Site January 2024
acres will be walked during MY2 and any noted Chinese privet will be treated during this site
visit.
1.7.2 Stream Geomorphology
A total of 14 cross sections were installed and geomorphology data collection for MY1 was
conducted on November 14 and 15, 2023. Summary tables and cross section plots are in
Appendix D. Overall, MY1 cross sections and profile relatively match the baseline. The reach
was designed as a brush/sand and silt bed channel with cobble stone added to the brush to
reduce buoyancy post construction. This cobble is already beginning to silt over post-
construction and the channel bed is expected to continue to move toward a sand and silt
bottom as monitoring continues. The three Enhancement cross sections (12, 13, and 14) show
the most changes in overlays likely due to the installed deflectors. The intent of the deflectors
was to constrict the channel and support formation of bed diversity. All three Enhancement
cross sections have shown some scouring suggesting the deflectors are functioning as
designed. Changes such as these are expected to continue overtime, so channel bed is not
expected to stay constant from year to year within the Enhancement reach. Additionally, it
should be noted that the naturally mucky bottom of this area of the stream prevents consistent
monitoring points as there is no solid bottom to rest the surveying rod on. This will also
contribute to changes seen in the bed of these three cross sections from year to year. With
these two factors in mind, RES will consider these cross sections to be stable if the banks and
any installed brush toe areas remain stable, and minor changes in bedform will be expected.

Visual assessment of the stream channel was performed to document signs of instability, such
as eroding banks, structural instability, or excessive sedimentation. The channel is transporting
sediment as designed and will continue to be monitored for aggradation and degradation.
1.7.3 Wetland Hydrology
A total of 10 groundwater wells with automatic recording pressure transducers were installed
throughout the wetland areas on April 4 and 5, 2023. Five groundwater wells (GW1, GW4,
GW6, GW7, and GW8) were installed in wetland re-establishment areas. Two groundwater
wells (GW3 and GW5) were installed in wetland enhancement areas, and one groundwater
well (GW 2) was installed in an upland area. Two groundwater wells (GW9 and GW10) were
installed in wetland preservation areas to serve as references. Out of the 10 wells, only GW4
and GW5 met the 12% hydroperiod success criteria in MY1, and both reference wells (GW9
and GW10) had moderate hydroperiods of 5% and 7% respectively. Hydroperiods ranged from
0 to 14% of the growing season. Wells were installed after the start of the growing season, so
future years will provide a more complete picture of the expected hydroperiods for each well.
Additionally, 2023 was a dry year in terms of precipitation. Hydroperiods should improve as
soil conditions improve and with a year of more normal precipitation.
2 METHODS
Stream cross section monitoring was conducted using a Topcon GTS-312 Total Station. Three-
dimensional coordinates associated with cross-section data were collected in the field (NAD83
White Hat Stream and 12 MY1 Report
Wetland Mitigation Site January 2024
State Plane feet FIPS 3200). Morphological data were collected at 14 cross-sections. Survey
data were imported into CAD, ArcGIS®, and Microsoft Excel® for data processing and
analysis.

The stage recorders documenting stream hydrology include an automatic pressure transducer
placed in PVC casing in a pool. The elevation of the bed and top of bank at each stage recorder
are used to detect bankfull events.

Vegetation success is being monitored at 18 fixed monitoring plots and 12 random monitoring
plots. Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording
Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and
density of planted species. Data are processed using the CVS data entry tool. In the field, the
four corners of each plot were permanently marked with PVC at the origin and metal conduit
at the other corners. Photos of each plot are taken from the origin each monitoring year. The
random plot data are collected in locations where there are no permanent vegetation plots.
Random plots are typically collected in the form of 100 square meter belt transects with
variable dimensions. Tree species and height are recorded for each planted stem and the
transects are mapped, and new locations will be monitored in subsequent years.

Wetland hydrology is being monitored to document success of wetland restoration areas as
well as conditions of wetland enhancement and preservation areas. This is accomplished with
10 automatic pressure transducer gauges (located in groundwater wells) that record daily
groundwater levels. Five groundwater wells were installed in wetland re-establishment areas;
two were installed in wetland enhancement areas; two were installed in wetland preservation
areas to serve as references; and one was installed in an upland area. One automatic pressure
transducer was installed above ground to record ambient air pressure and is used to correct
all other pressure transducers onsite. Gauges are downloaded quarterly and wetland
hydroperiods are calculated during the growing season. Gauge installation followed current
regulatory guidance. Visual observations of primary and secondary wetland hydrology
indicators are also recorded during quarterly site visits. As mentioned earlier, soil was
characterized at each groundwater well. Soil borings were taken at each groundwater well and
characterized in accordance with the Soil Characterization Data Forms provided in the USACE’s
Technical Standard for Water-Table Monitoring of Potential Wetland Sites, and includes
parameters of soil horizon depths, texture, colors, redoximorphic features, induration, and
roots, as well as a photo of each soil profile (Appendix E).
