There are several malfunctioning gauges on this site that may cause concern by the IRT. Ensure that the gauges are checked at least quarterly for MY7. KCI Response: Several of the gauges had batteries die during MY06. KCI has learned from this and other sites that the effective battery life of the gauges is between 5 and 6 years. Measures, including more frequent gauge downloads and replacement of gauges before the beginning of MY05, are being implemented to ensure data loss is kept to a minimum. 2. DMS will request concurrence for KCI to omit MY7 vegetation monitoring at the credit release meeting. KCI Response: KCI is prepared to bring this up at the credit release meeting. 3. The report states that gauges 1, 4, and 14 did not meet success criteria but two of the gauges are right on the credit line and at least one is completely lacking data. DMS suggests adding a statement or clarifying that hydroperiods of the groundwater gauges depict that the wetland credit line is generally drawn accurately to match project success hydrology. KCI Response: A statement clarifying this has been added to the report. 4. DMS recommends that KCI label the gauges with % hydroperiod on the CCPV to show IRT how this line is generally accurate. This is not required for MY6 but may be beneficial for the report and certainly for MY7. KCI Response: This will be added to the CCPV in MY07. Please contact me if you have any questions or would like clarification concerning these responses.

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 the 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. During the site’s sixth growing season, vegetation monitoring did Twin Bays Wetland Restoration Site KCI Associates of NC, PA DMS Project # 95363 2 2019– MY06 not take place as stipulated in the Mitigation Plan. Fourteen of the seventeen credit bearing groundwater monitoring gauges met the success criteria. Chinese privet (Ligustrum sinense) growing in the two fingers near the northeast corner of the site was cut and sprayed with herbicide in August 2018. An additional treatment of privet growing in these areas is planned for 2020. Summary information/data related to the occurrence of items such as 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 DMS 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 is based on the vegetative density estimated as woody stems/acre based on monitoring plot data. The site will demonstrate the re- establishment of targeted vegetative communities through the 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. No vegetation monitoring occurred during the sixth monitoring year, as stipulated in the Mitigation Plan. During an onsite meeting with the IRT on October 30, 2019, it was determined that vegetation monitoring did not need to be performed during Monitoring Year 7, due to the overwhelming success of the vegetation on site. 2.2 HYDROLOGY MONITORING Wetland hydrology is 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 nineteen automatic gauges that record water table depth. Daily data is collected from the automatic gauges over the 7-year monitoring period. Twin Bays Wetland Restoration Site KCI Associates of NC, PA DMS Project # 95363 3 2019– MY06 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 2019, the months of April and November experienced above average rainfall, while August, September, and October experienced average rainfall. The months of January, February, March, May, and June recorded below average rainfall for the site. Overall, the area experienced average rainfall during the 2019 growing season. With the exception of April, the first six months of the year were below average precipitation months. These months at the beginning of the growing season are when most of the gauges achieve success in a typical year, so these dry conditions likely contributed to any poor gauge results in 2019. During the site’s sixth growing season, fourteen of the seventeen credit-bearing gauges met the hydrologic success criteria. The three gauges that did not meet the success criteria were 1, 4, and 14. Gauge 1 has met the criteria for three of the previous five growing seasons. Gauge 4 malfunctioned throughout the growing season, and no viable data was collected, although it has had hydrology success in every previous growing season. Gauge 14 only collected data at the beginning of the growing season and then malfunctioned repeatedly for the rest of the growing season. That gauge has had hydrology success in four of the previous five growing seasons. Gauges 1 and 4 are both located right on the credit line and so are generally expected to be drier than other gauges located further into the wetland. KCI believes that the pattern of success seen in MY06 is evidence that the credit line is generally drawn accurately. In addition, one of the two non-credit bearing gauges also achieved the success criteria this year. This gauge (Gauge 6) has met the hydrology success criteria every previous growing season except for the first.
