69 Darlington Ave Wilmington, North Carolina RE: Meadow Spring Year 6 Monitoring Report (SAW-2016-01989) Casey,
Please find attached the Meadow Spring Year 6 Monitoring (MY6) Report. In Year 6, bankfull events were recorded on both stage recorders. In MY6, eight of the 17 wetland gauges met success with hydroperiods ranging from two to 45 percent. Groundwater Wells 1, 4, 4-B, and 7, and Reference 1 have all failed to meet successful hydroperiods each year. Additional analysis of the wetlands at risk can be found in the MY6 monitoring report and Appendices. Data supports the success of at least 10.153 WMUs at this time, more
than the 7.200 WMU credits that have already been released, leaving 2.953 WMU viable credits available. Furthermore, RES feels strongly that even more wetland areas will ultimately be successful and be deemed viable for credit generation. Vegetation plot monitoring was not conducted in year 6 according to the approved mitigation plan. In year
5, all of the 21 vegetation plots met the 260 stems per acre interim success criteria and greater than an average 7 feet. The two small areas of low-stem density with a combined total area of about 0.3 acres mentioned in the MY5 report were planted in December 2023. A third area of low stem density in Wetland F-B near cross
sections 19 and 20 noted during the IRT site visit in December was planted in March 2024. In May 2024, an area totaling approximately 0.2 acres of pines near vegetation plots (VP) 5 and 7 was removed. Additionally, RES planted livestakes along the stream within Wetland I to shade out the invasive parrotfeather. Visual assessments of the easement boundary found some minor scalloping along the northernmost boundary. This line had additional signs added and some 1-gallon trees planted before the 2024 growing season to help clarify the boundary. No other encroachments or evidence of cattle entry were noted.
NC IRT MY5 Review Comments:
The IRT had no additional comments on the MY5 credit release. The photos of the log sill repair at XS 16 as
well as the inundation from the beaver dam are included in Appendix B as requested by the IRT.
RES is requesting a 5% stream credit release (272.00 SMUs). Additionally, RES is requesting that last years’
scheduled Wetland Credits of 15% (Year 5 Monitoring) credit releases be released based on the revised estimate of total Wetland Mitigation Units (10.15 WMU) which would result in a 1.43 credit release. As for
2
the completion of the Year 6 monitoring report, RES expects that the 5% wetland credit release may be
withheld. Please see enclosed the credit release schedule and an updated credit ledger.
Thank you,

Stream and Wetland Mitigation Site November 2024
1 PROJECT SUMMARY
1.1 Project Location and Description
The Meadow Spring Mitigation Site (Site) is located within a watershed dominated by agricultural
land use in Johnston County, North Carolina, approximately three miles north of Smithfield. The
project streams and wetlands were significantly impacted by channelization, impoundment, and
cattle access. The project involves the restoration and protection of streams in the Neuse River
watershed and the restoration, enhancement, and preservation of adjacent riparian wetlands. The purpose of this mitigation site is to restore, enhance and preserve a stream/wetland complex located within the Neuse River Basin. The Site was designed in concurrence with the Meadow Spring Riparian Buffer and Nutrient Offset Mitigation Bank. The Site lies within USGS Hydrologic Unit Code (HUC) 03020201. The total easement area is 60.93 acres. The wooded areas along the easement corridor designated for restoration activities are classified as mixed hardwoods. Invasive species were present throughout the wooded areas. Restored channels were both laterally and vertically unstable,
impacted by cattle, have disturbed riparian buffers, and did not fully support aquatic life. Previous
stream conditions along the restoration reaches exhibited habitat degradation because of impacts
from livestock and impoundment to promote agricultural activities.
The Meadow Spring Site includes stream Priority I/II Restoration, Enhancement Levels I II and III,
Preservation and wetland re-habilitation, re-establishment, enhancement and preservation.
Priority I Restoration reaches incorporate the construction of a single-thread meandering channel,
with parameters based on data taken from the reference site described above, published empirical
relationships, NC Coastal Plain Regional Curves, and hydrologic and hydraulic analyses.
Wetland re-establishment occurred adjacent to Priority I Restoration reaches. The restoration
approach was to reconnect the floodplain wetlands to the stream, fill existing ditches, rough the floodplain surface, and plant native tree and shrub species commonly found in small stream swamp ecosystems. The wetland enhancement treatment included livestock exclusion, improving hydrology via pond removal and ditch plugging, and planting native tree and shrub species. The Site will be monitored on a regular basis and a physical inspection of the Site will be conducted at a minimum of twice per year throughout the seven-year post-construction monitoring period, or until performance standards are met. These site inspections will identify site
components and features that require routine maintenance. The measure of stream restoration
success will be documented by bankfull flows and no change in stream channel classification.
Sand bed channels are dynamic and minor adjustments to dimension and profile are expected.
The measure of vegetative success for the Site will be the survival of at least 210 seven-year old
planted trees per acre with an average height of 10 feet at the end of year seven of the monitoring
period.
Upon approval for closeout by the Interagency Review Team (IRT), the site will be transferred to
the North Carolina Wildlife Habitat Foundation (NCWHF). The NCWHF will be responsible for
Meadow Spring 2 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
periodic inspection of the Site to ensure that restrictions required in the Conservation Easement
or the deed restriction document(s) are upheld. Endowment funds required to uphold easement
and deed restrictions will be negotiated prior to site transfer to the responsible party.
1.2 Project Goals and Objectives
The 2010 Neuse RBRP identified several restoration needs for the entire Neuse River Basin, as well as for HUC 03020201, specifically. The Site is in HUC 03020201100050 (Neuse River), a Targeted Local Watershed (TLW) that exhibits both the need and opportunity for wetland, stream, and
riparian buffer restoration. The watershed includes 52 square miles of area, with 31 percent of the
106 stream miles lacking wooded buffers. Thirty-seven percent of the watershed is used for
agricultural purposes with 13 animal operations occurring in the watershed. Impervious surface
near the town of Smithfield is increasing and set to surpass the critical seven percent benchmark
(NCDMS 2010).
The Site was identified as a stream and buffer restoration opportunity to improve water quality,
habitat, and hydrology within the Neuse River Basin. This project is intended to provide Stream
Mitigation Units to be applied as compensatory mitigation for unavoidable authorized impacts to
waters of the US under Section 404 of the Clean Water Act (33 U.S.C. 1344) and support the overall
goal of “no net loss” of aquatic resources in the United States. The Site is located within the
downstream end of HUC 03020201 and includes an unnamed tributary that directly discharges into the Neuse River. Many of the project design goals and objectives, including restoration of riparian buffers to filter runoff from agricultural operations and improve terrestrial habitat, and construction of in-stream structures to improve habitat diversity, will address the degraded water quality and nutrient input from farming that were identified as major watershed stressors in the 2010 Neuse RBRP. The project goals will be addressed through the following project objectives:
• Design and construct stable stream channels with appropriate pattern, dimension, and profile based on reference reach conditions.
• Exclude livestock permanently from streams and their associated buffers as well as surrounding wetlands.
• Reduce bank height ratios to less than 1.2 and increase entrenchment ratio to greater than 2.2 in accordance to the Wilmington District Stream and Wetland Compensatory
Mitigation Update Guidance.
• Increase forested riparian buffers to at least fifty feet on both sides of the channel along
the project reaches with an appropriate riparian plant community.
• Re-establish, rehabilitate, and enhance riparian wetlands by raising stream bed elevations,
plugging surface ditches, and planting native wetland plant species in order to maintain
appropriate soil series saturation/hydroperiod thresholds during the growing season.
• Preserve and enhance of hydrology in existing riparian wetland seeps.
• Establish a permanent conservation easement on the Site.
Meadow Spring 3 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
• Remove invasive species from the riparian buffer and wetland areas to support the
colonization and survival of native riparian buffer species.
1.3 Project Success Criteria
The Site follows the USACE 2003 Stream Mitigation Guidelines and the “Wilmington District Stream and Wetland Compensatory Mitigation Update” dated October 24, 2016. Cross section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream and wetland
hydrology data and visual monitoring will be reported annually.
1.3.1 Stream 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 as-built cross-sections. 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 reaches. 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 absence of developing 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 for Johnston County upon which to base a normal rainfall amount and average growing season. The closest
comparable data station was determined to be the WETS station for Smithfield, NC. The growing
season for Johnston County is 233 days long, extending from March 18 to November 6, 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 the Bibb soil of 12-16 percent of the growing season. The hydrology success
criterion for the Site 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 27 days) at
each groundwater gauge location. Based on the extensive management history of the Site and
Meadow Spring 4 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
soil compaction, RES expects a slightly reduced hydroperiod in the monitoring years (MY) 1 and
2.
1.3.3 Vegetation Success Criteria
Specific and measurable success criteria for plant density within the riparian buffers on the site
follow IRT Guidance. Vegetation monitoring plots are a minimum of 0.02 acres in size and cover
a minimum of two percent of the planted area. Vegetation monitoring shall occur annually
between July 15 and leaf drop. The interim measures of vegetative success for the site are the
survival of at least 320 planted three-year old trees per acre at the end of Year 3, 260 five-year
old trees that are at least 7 feet tall at the end of Year 5, and the final vegetative success criteria
is 210 trees per acre with an average height of ten feet at the end of Year 7. Volunteer trees are
to be counted, identified to species, and included in the yearly monitoring reports, but do not count towards the success criteria of total planted stems.
1.4 Project Components
The project area is comprised of an easement area along an unnamed tributary to the Neuse River. The easement is separated by an existing power easement and three agricultural crossings. The project is divided into northern and southern portions by the existing power easement. The northern portion of the project includes Reaches S1, S2, S5, S6A and S6B. The southern portion of the project includes Reaches S7, S9, S11, S12 and S13. The stream and wetland mitigation components are summarized below.

1.5 Design/Approach
1.5.1 Stream
The Meadow Spring Site includes Priority I/Priority II Restoration, Enhancement Level I,
Enhancement Level II, Enhancement Level III. Priority I Restoration reaches incorporate the design
of a single-thread meandering channel, with parameters based on data taken from the reference
site described above, published empirical relationships, NC Coastal Plain Regional Curves, and
hydrologic and hydraulic analyses. As a result of the restoration of planform and dimension,
frequent overbank flows and a restored riparian buffer will provide the appropriate hydrology and
sediment transport throughout this coastal plain watershed. All non-vegetated areas within the
easement were planted with native vegetation and any areas of invasive species were removed
and/or treated.
• Reach S1 (STA 03+50 to STA 06+00) – Reach beginning at northwestern limits of the
project flowing southeast to Reach S2 totaling 250 linear feet of Enhancement Level II.
Row crops and active pasture were located adjacent to the reach. Enhancement involved revegetating the buffer with native vegetation.
• Reach S2 (STA 06+00 to STA 11+00) – Reach begins at the downstream end of Reach S1 and flows southeast through what was active pasture to Reach S6A. Reach S2 totals 500 linear feet of Enhancement Level I. Active pasture and row crops used to surround this reach. Enhancement involved revegetating the buffer and stream stabilization of localized erosion with the installation of log cross vanes and sills.
• Reach S5 (STA 00+76 to STA 03+07) – Reach begins north of Reach S6A and flows south through active pasture to a confluence with Reach S6A totaling 231 linear feet of Priority I and II Restoration. Active pasture and maintained lawn used to surround this reach.
Restoration included meandering the channel within the valley, backfilling the old stream,
reconnecting to its floodplain, and restoring hydrology to drained wetlands.

Meadow Spring 7 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
1.5.2 Wetland
The Meadow Spring Site offers a total ecosystem restoration opportunity. As such, the wetland restoration and enhancement are closely tied to the stream restoration. The Site provides 14.41
WMUs through a combination of wetland re-establishment, rehabilitation, and enhancement.
Because of the sites observed soil characteristics and landscape position, a combination of
wetland re-establishment, rehabilitation, and enhancement was incorporated. In wetlands WH,
the non-jurisdictional area, hydrologic restoration, at a credit ratio of 1:1, was accomplished by
plugging the existing incised channel to restrict drainage and allowing a natural hydroperiod to
return. In addition, re-constructing a stream channel at a higher bed elevation in the natural valley,
backfilling to create shallow depressions within the old channel, and the removal of spoil from
pond excavation along the floodplains aids in the restoration of a natural floodplain surface
relative to the surrounding landscape. Due to compaction and long-term agricultural use, a shallow ripping of the surface along the contour to a depth of eight to ten inches creates adequate porosity for infiltration and storage, provides microtopographic relief, and should improve vegetative survival and growth. As part of the wetland re-establishment in wetland WI, at a credit ratio of 2:1, the pond was removed. The construction of a farm pond has altered surface drainage and placed spoil across the floodplain. The stream was reconnected to the floodplain and in addition to out of bank events the large perennial spring serves as a source for hydrology for the re-established wetlands. Retention and storage within the floodplain has returned to a natural state having an increased hydroperiod.
In wetland WF-B, a credit ratio of 3:1 was implemented for wetland enhancement. This wetland
has been impacted by channel incision and active management for agriculture in the past. The
wetland mitigation treatment consisted of reconnecting the stream to the floodplain and
replanting disturbed areas. These activities result in a much healthier, better functioning wetland.
In wetland WG, the large disturbed Neuse River floodplain area, a credit ratio of 3:1 was
implemented for wetland enhancement in the areas that are planted (WG-A) and an enhancement
credit ratio of 5:1 in the areas not planted (WG-B). This wetland has been actively managed for
agriculture and waterfowl through drainage manipulations and tree clearing. The wetland mitigation treatment was primarily re-planting the disturbed areas, plugging the main ditch, and removing existing berms within the wetland. These activities result in a large floodplain slough with a diversity of microhabitats.
1.6 Construction and As-Built Conditions
Stream construction and planting was completed in June 2019. The Meadow Spring Mitigation
Site was built to design plans and guidelines. A redline version of the as-built survey is included
with the sealed plat in the As-Built Baseline Monitoring Report. Project credits are based on design
centerline, but as-built stream lengths are shown on Table 1.
Meadow Spring 8 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
1.7 Wetland Risk
Upon completion of the MY3 and MY4 monitoring and report submittals, the IRT declined to release the associated wetland credits due to concerns related to the wetlands on site. Four of 11 wetland gauges had not met the performance criteria for each year they’d been installed. After an evaluation of wetland conditions on site, a general wetland delineation of areas surrounding the at-risk wells (performed on February 10, 2022), and an analysis of hydrology data, it was concluded
that approximately 1.80 acres of wetlands were at risk of not meeting successful performance
criteria, at that time. Wetland H (WH) and Wetland I (WI), on the western side of the project, were
the two wetlands with a number of unsuccessful gauges. Additionally, in MY4 two of three
supplemental gauges failed to meet success criteria. However, this was a difficult year to make a
determination as it was well cited across the state that the state was in a drought. In MY 5, three
gauges which had previously failed were successful. Two more gauges were added in February
2023 and were also successful.
In MY6, 9 of the 17 gauges have not met the success criteria. This includes the two gauges that
were added in February 2023 and two of the three gauges that were added in 2022.
Approximately 0.14 acre of Wetland I and 2.11 acres of Wetland H require more information to
determine wetland success. Approximately 2.069 acre of Wetland H is not meeting success criteria.
In February 2024, prior to the growing season, the Meadow Spring Mitigation Bank experienced precipitation below normal limits (0.66 inches). This likely impacted the extent of the hydroperiod for many of the wetlands. It is likely that if the wetlands received precipitation levels within normal limits in February, many of the wetlands would have experienced a hydroperiod starting at the beginning of the growing season (March 18, 2024), increasing the hydroperiod by 2-4%. Considering the precipitation received at the start of the growing season, wetlands B, D, E, F, and G are on track to meet success criteria.
1.8 Year 6 Monitoring Performance (MY6)
The Meadow Spring Year 6 Monitoring activities were performed in August and October 2024. All MY6 data is present below and in the appendices. Due to a broken ambient barometric gauge at the Meadow Spring site, the hydrology data was processed using the ambient gauge from the
adjacent Poplar Creek mitigation bank. The Meadow Spring gauge was replaced in September
2024. The Site is on track to meeting vegetation and stream success criteria while wetland success
criteria is being met for most wetland areas but not all.
1.8.1 Vegetation
Vegetation data was not collected in MY6 per the approved mitigation plan. It will be collected
again in MY7. Monitoring of the 18 permanent vegetation plots and three random vegetation plots was last completed in September 2023. Vegetation data from MY5 are in Appendix C, associated photos are in Appendix B, and plot locations are in Figure 2; Appendix B. MY5 monitoring data indicates that all of the 21 plots are exceeding the interim success criteria of 260 planted stems per acre.
Meadow Spring 9 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous
vegetation is becoming well established throughout the project. The areas of loblolly pine (Pinus
taeda) noted on the MY5 CCPV have been treated, along with some additional areas that have been noted during site walks (Figure 2; Appendix B). The two small areas of low-stem density with a combined total area of about 0.3 acres mentioned in the MY5 report were planted in December 2023 (Figure 2; Appendix B). The area received approximately 50 1-gallon container trees. A third area of low stem density in Wetland F-B near cross sections 19 and 20 noted during the IRT site visit in December was planted in March 2024. Approximately 165 1-gallon container trees were added within and adjacent to Wetland H and approximately 50 1-gallon container trees were added within Wetland F-B. Species included redbud (Cercis canadensis), flowering dogwood
(Cornus florida), American holly (Ilex opaca), serviceberry (Amelanchier arborea), sweetbay
magnolia (Magnolia virginiana), sweetleaf (Symplocos tinctoria), red mulberry (Morus rubra),
Chickasaw plum, blackgum (Nyssa sylvatica), black cherry (Prunus serotina), American elm (Ulmus
americana), river birch (Betula nigra), overcup oak (Quercus lyrata), swamp chestnut oak (Quercus
michauxii), bald cypress (Taxodium distichum), swamp tupelo (Nyssa biflora), buttonbush
(Cephalanthus occidentalis), green ash (Fraxinus pennsylvanica), water oak (Quercus nigra),
persimmon (Diospyros virginiana), Sycamore (Platanus occidentalis), and American hazelnut
(Corylus americana). Supplemental planting locations are depicted in Figure 2; Appendix B.
In May 2024, an area totaling approximately 0.2 acres of pines near vegetation plots (VP) 5 and 7
was removed. Additionally, RES planted livestakes along the stream within Wetland I to shade out
the invasive parrotfeather Figure 2; Appendix B. Visual assessments of the easement boundary found some minor scalloping along the northernmost boundary. This line had additional signs added and some 1-gallon trees planted before the 2024 growing season to help clarify the boundary. No other encroachments or evidence of cattle entry were noted.
1.8.2 Stream Geomorphology
Geomorphology data was not collected in MY6 per the approved mitigation plan. It will be
collected again MY7. Data collected in MY5 is included in Appendix D for reference.
In November 2023, RES observed erosion on the inner meander of the stream at XS 16. In December 2023, the log sill was repaired by notching the top of the log and adding larger sediment around the outer meander to distribute flow. Some material was also placed under the log sill to prevent flow underneath. In January 2024, RES noticed that the log sill was too high and that the added riprap would not allow for fish passage. Smaller stones were added to turn the area into a riffle in April 2024. Photos of the log sill repair are included in Appendix B. No other stream problem areas were observed in MY6. Visual assessment of the stream channel was performed to document signs of instability, such as eroding banks, structural instability, or excessive sedimentation. Generally, the channel is transporting sediment as designed and will continue to be monitored for aggradation and degradation.

Stream and Wetland Mitigation Site November 2024
1.8.3 Stream Hydrology
Two stage recorders were installed in June 2019 to document bankfull events. One stage recorder
on Reach S6-B and one stage recorder on Reach S11. The stage recorder on Reach S6-B recorded
two bankfull events in MY6 with the highest stage measuring 0.48 feet above top of bank,
occurring September 30, 2024. The stage recorder on Reach S11 recorded 21 bankfull events with
the highest stage measuring 9.27 feet above top of bank, occurring on August 9, 2024. Reach S11
experiences extreme flooding from backwater of the Neuse River. Stage recorder locations can be
found on Figure 2; Appendix B and associated data is in Appendix E.
During the site visit with the IRT in December, 2023, RES noted that a beaver dam was recently
found in WG-B that backs up a large ponded area in the wetland. The area was examined and the IRT felt like the dam could remain as it is backing up a wetland. In February 2024, a second small beaver dam was identified at the eastern portion of the site within Wetland G-B. The location of both dams is included in Figure 2; Appendix B.
1.8.4 Wetland Hydrology
Following the general delineation conducted in February 2022, three groundwater wells were
added to Wetlands I and H (WI and WH); each named for their proximity to existing groundwater
wells: GW1-B, GW4-B, and GW7-B. The adjusted locations of the wells were chosen based on field
observations made during the general delineation and were installed on February 24, 2022.
To gather and document hydrology for some other, unrepresented wetland areas, two additional
wetland gauges were installed in February 2023. GW5-B was installed in the western portion of
wetland WH and GW7-C was installed further upstream of GW7-B within WH.
Eight of the 17 groundwater wells met the 12 percent hydroperiod success criteria during MY6.
GW1, GW4, GW4-B, GW7, and the reference well have never met the success criteria to date.
Overall, hydroperiods ranged from two to 45 percent in year six. As for the newest wetland gauges installed in February 2023, GW5-B and GW7-C recorded a 9% and 11% hydroperiod in their second season, respectively. Details about the success of each of the wetlands is described below. Updated groundwater well locations can be found on Figure 2 and the data is in Appendix E. The “Wetland Risk Map” (Figure 3) initially presented in the MY4 report has been updated to depict all wetland gauges and their current success status. Figure 3 is included along with the hydrology data in Appendix E. The map displays areas, specifically in the westernmost portion of
the easement, that are at risk of credit loss due to consistently low hydroperiods or need more
time and data before credit allocation takes place. The calls are as follows:
All Rehabilitation (1.5:1): 0.636 credits
All Enhancement (3:1; 5:1): 5.507 credits
Parts of WI (Re-establishment, 2:1): 1.357 credits
Parts of WH (Re-establishment, 1:1): 2.652 credits
Meadow Spring 11 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
Total of 10.153 credits
Wetland WB:
• Groundwater well (GW) 3 was successful from 2020 through 2023. The low levels of precipitation in February 2024 likely impacted the extent of the hydroperiod for this wetland. In 2024, GW3 experienced 11% hydroperiod (September 14 through October 8, 2024), only 1% below wetland success.
WF (A and B), WG (A and B):
• All wetlands have met success and are not at risk of credit loss.
• Evidence of over 6 feet of flooding was observed within Wetlands F-B and G-B in August
2024.
Wetland I (WI), Re-establishment (2:1): 2.85 acres:
• GW1 recorded an 11% hydroperiod in MY6, a 3% hydroperiod in MY5, a 4% hydroperiod
in MY4, and 6-9% in previous years, (Table 13); but GW1-B, installed slightly upstream,
displayed a 45% hydroperiod in MY6, a 36% hydroperiod in MY5 and 20% hydroperiod in
MY4. GW1 was installed on a terrace between the confluence of S2 and a perennial spring,
but other wetland indicators still exist such as wetland soils and hydrophytic vegetation. It
is possible that this location has shown more drainage effect from the open channels
surrounding it than anticipated, or the wetland gauge (groundwater well) itself is
malfunctioning such as improper installation, cracking, or penetrating a restrictive layer.
Regardless, for the time being, the area around GW1 has been designated to “need more
information” before making a decision about cutting credits permanently. If GW1-B
continues to display appropriate hydrology, that will be considered when delineating areas of suitable wetland to remain. Wetland I has been divided, and portions of it, specifically a 0.14-acre area around GW1, are not included in the calculations for successful credit areas during Year 6; however, with more information and time, the original crediting amount will be considered for this wetland if the data warrants.
• GW 2 was successful from 2019 through 2021, and again in 2023. In 2024, GW2 recorded a 12% hydroperiod. This wetland gauge and surrounding area is not of concern.
Wetland H (WH), Re-Establishment
• Compared to previous years in 2022 and 2023, GW4 has shown improvement with a 9% hydroperiod in 2024. Data from GW4-B, installed northeast of GW4 in February 2022, had a 6% hydroperiod in MY6. The general area surrounding GW4 and GW4-B is at-risk of not meeting the performance standard and is not included in the successful credit calculations for MY6. However, the wetland gauges will continue to be monitored in following monitoring years.
• GW5 was trending toward success with the hydroperiod improving from 2% in MY1 to 8%
and 7% in MY2 and MY3, respectively; GW5 recorded 3% hydroperiod in MY4 during a
drought but recovered in MY5, showing the positive trend continuing with a resulting
Meadow Spring 12 Year 6 Monitoring Report
Stream and Wetland Mitigation Site November 2024
hydroperiod of 14%. In MY6, GW5 recorded a 12% hydroperiod. This area, surrounding
GW5, has been designated to “need more information.” However, RES feels that this area
shows all signs that it will meet success criteria as a re-established wetland. In February 2023, RES installed an additional wetland gauge (GW5-B) upstream and to the west of GW5 to capture additional hydrology data. GW5-B documented a 14% hydroperiod for MY5 and a 9% hydroperiod in MY6. GW5-B is in an area that also exhibits other wetland characteristics, like GW5. Based on current information, RES there is strong likelihood that some or all of the wetland area represented by GW5 and especially GW5-B may ultimately be included for credit. For the time being, this area will not be considered in successful credit calculations for MY6; however, the groundwater wells will continue to be monitored
to hopefully document improving hydrology in following monitoring years.
• GW7 remained unsuccessful in MY6 for the sixth consecutive year. However, GW7-B was
successful in MY5, and recorded a 10% hydroperiod in MY6. A few factors could have
played a role in this area’s performance in MY5, including the slough to the north that was
diverting water has now been plugged since of August 2022 and a more normal year of
rainfall. In February 2023, RES installed an additional wetland gauge (GW7-C) upstream
and to the northwest of GW7-B to capture additional hydrology data in an otherwise
unrepresented area of wetland WH. GW7-C documented an 11% hydroperiod for MY6.
The area of wetland represented by wetland gauges GW7, GW7-B, and GW7-C are still
designated to “need more information.” Based on current information, RES thinks there is
a likelihood that some of the wetland area represented by GW7 may ultimately be
excluded from credit while the wetland areas represented by GW7-B and GW7-C may ultimately be included for credit. For the time being, these areas will not be considered in successful credit calculations; however, the wetland gauges will continue to be monitored in following monitoring years.
• GW6 exceeded the success criteria, displaying a 43% hydroperiod in MY6. This area is considered in successful credit calculations as it has been successful for four consecutive years.
• Field observations support the presence of wetlands within portions Wetland H (WH). This wetland has been divided into three categories: 1) areas that are meeting wetland success
and do not need supplemental data to prove success (2.652 acres), 2) areas that need more
information and time in order to make a decisive call whether or not the area is passing
wetland success criteria (2.115 acres), 3) areas that are at risk of not meeting performance
criteria (2.069 acres). The areas that need more information and those at risk are not
included in the calculations for successful credit areas during Year 6.
• RES believes with continued normal rainfall amounts, portions of this area have potential
to improve hydrology in the following years; however, not all portions of the originally
proposed wetland are viable for successful crediting.
Data supports the success of at least 10.153 credits at this time, more than the 7.200 WMU credits
that have already been released, leaving 2.953 WMU viable credits available.

2 METHODS
Stream monitoring was conducted using a Topcon GTS-312 Total Station. Three-dimensional
coordinates associated with cross-section data were collected in the field (NAD83 State Plane feet
FIPS 3200). Morphological data were collected at 24 cross-sections. Survey data were imported
into CAD, ArcGIS®, and Microsoft Excel® for data processing and analysis. The stage recorders
include an automatic pressure transducer set in PVC piping in the channel. The elevation of the
bed and top of bank at each stage recorder location was recorded to be able to document
presence of water in the channel and out of bank events. Visual observations (i.e. wrack or debris
lines) will also be used to document out of bank events.
Vegetation success is being monitored at 18 permanent monitoring plots and three 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 to be taken from the origin each monitoring year. The random plots are to be collected in locations where there are no permanent vegetation plots. Random plots will most likely be collected in the form of 100 square meter belt transects with variable dimensions. Tree species and height will be recorded for each planted stem and the transects will
be mapped and new locations will be monitored in subsequent years.
Wetland hydrology is monitored to document success in wetland restoration and enhancement
areas where hydrology was affected. This is accomplished with 17 automatic pressure transducer
gauges (located in groundwater wells) that record daily groundwater levels. Sixteen have been
installed within the wetland crediting area and one within reference wetland areas. One automatic
pressure transducer is installed above ground for use as a barometric reference. 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.
