DMS Project # 95363 2015— MY02
1.0 EXECUTIVE SUMMARY / PROJECT ABSTRACT
The Twin Bays Wetland Restoration Site, (TBWRS) completed in March 2014, restored 10.6 acres of
non -riparian wetland along with 0.4 acre of upland preservation. The TBWRS is a non -riparian wetland
system in the Cape Fear Basin (03030007 8 -digit HUC) in southern Duplin County, North Carolina. The
project is located in the 14 -digit HUC 03030007090040 (Rock Fish Creek), which DMS has identified as
a Targeted Local Watershed (TLW) (NCDENR, EEP 2009).
The project site is protected by an 11.72 -acre permanent conservation easement held by the State of North
Carolina. TBWRS is located on a single parcel located off of Cornwallis Road approximately two miles
northwest of Wallace, North Carolina. The project site is bounded by Cornwallis Road to the west, a ditch
along the property line to the south, and agricultural land to the east and north. Prior to construction, the
site was actively used for row crop farming. The site had a long history of hydrologic modification in
order to allow for farming to take place on the property.
The Cape Fear River Basin Restoration Priorities state the goals for the TBWRS's 14 -digit HUC are to
expand restoration opportunities and repair riparian buffers (NCDENR EEP, 2009). The project goals for
TBWRS are in line with the basin priorities and include the following:
- Slow and treat the runoff of upslope agricultural drainage.
- Restore a Hardwood Flats Community.
- Develop valuable wetland habitat niches within a drained agricultural landscape.
The project goals will be addressed through the following objectives:
- Fill field ditches to restore surface flow retention and elevate local groundwater levels.
- Redevelop longer wetland flow patterns to increase surface flow retention time.
- Modify an existing pond to its natural seep condition to feed the downslope wetland.
- Restore a native forested hardwood wetland community using natives trees and seed mixes.
There are three non-credit generating areas on the site. There is 0.4 -acre of uplands located in the forested
northeastern corner of the project boundary. This area remained undisturbed and is included in the
TBWRS conservation easement. There is a 0.2 acre utility easement on the west side of the site along
Cornwallis Road that remained undisturbed. Additionally, the southernmost ditch, located adjacent to
project easement, was left open and not filled. It is anticipated that leaving this ditch open will have
minimal impacts to the overall hydrologic performance of the site. The hydrologic influence of this ditch
was modeled using Lateral Effect, a software program that determines the lateral effect of a drainage
ditch or borrow pit on adjacent wetland hydrology (NCSU BAE, 2011). This analysis determined that the
potential horizontal drainage influence averages 76'. Due to the fact that the southern ditch cannot be
filled because of the potential for hydrologic trespass, the area immediately adjacent to the ditch will not
be a credit generating part of the site. It is assumed that with the onsite modifications, such as filling
ditches and surface roughening, the entire site will have more surface and groundwater, which may
decrease the effect of the ditch. For this reason, the non-credit generating portion of the site is assumed to
be half of the zone of influence for the ditch.
The TBWRS provided mitigation for wetland impacts within Hydrologic Unit 03030007 by restoring
10.6 acres of wetland and preserving 0.4 -acre of uplands, generating 10.6 riparian wetland mitigation
units (WMU's). The TBWRS will be monitored to determine if the project is on -track to meeting
jurisdictional wetland status. The wetland site will be deemed successful once hydrology is established
and vegetation success criteria are met.
Summary information/data related to the occurrence of items such as beaver or encroachment and
statistics related to performance of various project and monitoring elements can be found in the tables and

figures in the report appendices. Narrative background and supporting information formerly found in
these reports can be found in the Baseline Monitoring Report and in the Mitigation Plan documents
available on the DMSs website. All raw data supporting the tables and figures in the appendices are
available from DMS upon request.
2.0 MONITORING RESULTS
The TBWRS will be monitored to determine if the project is on -track to meeting jurisdictional wetland
status. The wetland restoration area will be deemed successful once hydrology is established and
vegetation success criteria are met. The site will be monitored for at least seven years or until the success
criteria are achieved.
2.1 VEGETATION MONITORING
The success criteria for the planted species in the mitigation area will be based on survival. The site will
demonstrate the re-establishment of targeted vegetative communities based on survival and growth of
planted species and volunteer colonization, with an average stem density of 320 stems/acre after three
years, 288 stems/acre after four years, 260 stems/acre after five years, and 210 stems/acre after seven
years to be considered successful. To determine the success of the planted mitigation area, ten permanent
vegetation monitoring plots (10 by 10 meters) have been established in the wetland restoration area at a
density that represents the total mitigation acreage. The average density of these plots will determine
whether the site meets the success criterion.
The second -year vegetation monitoring was based on the Level 2 CVS-EEP vegetation monitoring
protocol. The site's average density for this monitoring period was 983 planted stems/acre. This
represents an increase from the first year of monitoring, which is due to a supplemental planting that KCI
conducted in March 2015. All ten plots had greater than 320 planted stems/acre. Including volunteers, the
site averaged 1,117 total stems/acre. In general the site is well vegetated, with widespread herbaceous
coverage and healthy planted stems.
2.2 HYDROLOGY MONITORING
Wetland hydrology will be monitored with a series of automatic gauges that record water table depth. The
site must present continuous saturated or inundated hydrologic conditions for at least 8% of the growing
season with a 50% probability of reoccurrence during normal weather conditions. A "normal" year is
based on NRCS climatological data for Duplin County using the 30th to 70th percentile thresholds as the
range of normal as documented in the USACE Technical Report "Accessing and Using Meteorological
Data to Evaluate Wetland Hydrology, April 2000." The soil survey for Duplin County does not contain
growing season data; therefore, due to its close proximity, the Sampson County soil survey was used. The
estimated growing season begins March 18 and ends November 11 (239 days). The water table of the
restored wetlands must be within 12" of the soils surface continuously for at least 8% (19 days) of the
239 -day growing season. Wetland hydrology will be monitored with sixteen automatic gauges that record
water table depth. Daily data will be collected from the automatic gauges over the 7 -year monitoring
period.
Due to the inherent variability in the site's soils and associated drainage characteristics, it is unlikely that
the project will exhibit uniform hydrologic conditions across the site, making a single hydrologic
performance criterion unrepresentative of the site's performance. As such, the gauge data can be
evaluated and presented as a spatial average with each gauge representing the area half the distance to
adjacent gauges. The spatial average will be the calculated value for comparison with the performance
standard for credit validation. Gauges representing areas not achieving a minimum of 6.5% saturation will
Twin Bays Wetland Restoration Site KCI Associates of NC, PA
DMS Project # 95363 2 2015— MY02
be considered non -attaining even if the spatial average exceeds the credit validation performance
standard.
To monitor the effect of the unfilled ditch described in Section 1.0, four sets of coupled gauges were
installed perpendicular to the unfilled ditch. Each set includes a gauge that is 40' from the open ditch and
another that is 75' from the ditch. An additional two gauges were installed between the coupled gauges to
monitor hydrology less than 40' from the open ditch in the non-credit bearing zone.
The daily rainfall data were obtained from the NC State Climate Office for a local weather station in
Jacksonville, NC. In 2015, the months of February, May, October and November experienced above
average rainfall, while January, April, June, August, and September experienced average rainfall. The
months of March, and July recorded below average rainfall for the site. Overall, the area experienced
average rainfall during the 2015 growing season.
During the site's second growing season, all four of the gauges located 75' from the ditch had continuous
saturation within 12 inches of the ground surface for 8% (19 days) of the 239 day growing season (March
18 to November 11). All four of the gauges located 40' from the ditch also met this metric while only one
of the two gauges located less than 40' from the ditch achieved 8% continuous saturation. A new gauge
(Gauge 17) was installed in the restoration area before the start of the 2015 growing season. No gauges in
the restoration area were below 8% saturation. Since no gauges were below 6.5% continuous saturation,
all gauges were used in the analysis to determine the spatial average for the hydrology of the entire site.
This analysis is based off percent saturation contours for the restoration area calculated from the gauge
data. Following the method described above and as illustrated in the figure in Appendix D, it is
determined that based on the spatial average, the site was continuously saturated for 30.6% of the growing
season and met the hydrology success criteria of 8% for the second year of monitoring.
3.0 METHODOLOGY
The CVS-EEP protocol, Level 2 (http://cvs.bio.unc.edu/methods.htm) was used to collect vegetation data
from the site. The vegetation monitoring was completed on June 30, 2015.
