The Site is owned in fee by the State of North Carolina. To access the Site from Hertford, drive north along US -17 and turn right onto New Hope Rd and follow for approximately 13 miles and turn left on Little River Shores Rd, turn left onto Tuscarora Trail and left on Norma Dr. The Site is on the left approximately 0.1 mile down Norma Dr. It is situated in the Coastal Plain physiographic region and the Pasquotank River Basin (Hydrologic Unit 03010205). The Site encompasses approximately 48 acres of former agriculture land and has a direct hydrologic connection with the Little River. The Site watershed consists of agricultural land and forest. There is no impervious area within the drainage area. The drainage area for the Site is 136 acres at the lower end of the stream. Prior to construction activities the stream was deepened and channelized and the surrounding wetland complex was drained for row crop agricultural production. These modifications resulted in significant alterations to surface and groundwater hydrology in addition to degraded aquatic and terrestrial habitats within the Site. 1.2 Project Goals and Objectives The Site is located in the Pasquotank River Basin; eight digit CU 03010205 and the 14 -digit HUC 03010205060020. The Pasquotank River Basin Restoration Priorities (EEP, 2009) restoration goals for CU 03010205 include supporting implementation of the NC Coastal Habitat Protection Plan (NCCHPP). The following are the goals of the NCCHPP: • Improve effectiveness of existing rules and programs protecting coastal fish habitats • Identify, designate, and protect strategic habitat areas. • Enhance habitat and protect it from physical impacts. • Enhance and protect water quality. In addition to the above mentioned CU goals the following are Site specific goals established in the mitigation plan (NCDENR, 2012): • Restore ditched wetlands to improve the habitat, fishery and flood control functions; • Reduce sediment loading and other pollutants from the surface runoff by increasing the soils retention, filtration and nutrient uptake functions of wetland and riparian areas; • Restore and protect wildlife corridors and other key links to high value habitat areas; and • Restore and protect natural breeding, nesting and feeding habitat to promote species richness and diversity. The goals established in the 2012 mitigation plan were addressed through the following project objectives: Promote wetland hydrology by filling drainage ditches; Reduce pollutant runoff by grading the headwater valley for increased residence time of stormflows; Promote wildlife habitat by reforestation with native hardwoods. Draft Monitoring Report Year 3 (2017) Page 1 Watts Site, Perquimans County, NC Prepared by Ecological Engineering, LLP November 2017 1.3 Project Success Criteria The stream and wetland restoration success criteria for the Site were established in the approved mitigation plan. The success criteria were discussed with the Interagency Review Team (IRT) during the finalization of the mitigation plan. The agreed upon success criteria are a compromise between the current requirements in the Monitoring Requirements and Performance Standards for Compensatory Mitigation in North Carolina (USACE, 2013) and the success criteria found in the Information Regarding Stream Restoration in the Outer Coastal Plain of North Carolina (USACE, 2005) which was the current reference document when the Site was originally acquired for mitigation. The stream and wetland restoration and enhancement sections of the project were assigned specific performance criteria components for hydrology, vegetation and morphology (streams only). Performance criteria will be evaluated for a minimum of five years post -construction monitoring. If all performance criteria have been met the Division of Mitigation Services (DMS) may propose the Site for closeout after five years of monitoring. The project success criteria for stream, wetland and vegetation are as follows: • Stream restoration success includes visual documentation of flow within the low point of the valley, during monitoring years 1-4 and visual documentation of a primary flow path, stream channel or ordinary high water mark, post monitoring year 4; • Wetland hydrology success will include a minimum of a 8% hydroperiod in years of normal rainfall; • Vegetation success will include stem densities of 320 stems/acre in MY3 and 260 stems/acre in MY5. Two pressure transducers were installed but are not related to project success. The information gathered from the transducers will be included in the monitoring report as supplemental data. 1.4 Annual Monitoring Results The headwater channel was visually assessed two times throughout MY3 for success criteria. During the winter the channel exhibited several visual indicators for the MY 1-4 success criteria. Wrack lines were observed adjacent to the channel, vegetation was laid over in the direction of stream flow, a small bank was starting to form near the upstream portion of the stream, and standing water was also observed (Appendix D). The stream restoration met the success criteria described in the mitigation plan. Additionally, the three (3) cross-sections were stable throughout MY3 and the pressure transducers demonstrated 325 consecutive days of surface water in the restored channel. There were 98 consecutive days with greater than two inches of water in the headwater channel. Six groundwater gauges were installed to determine the wetland hydroperiod. Four of the six groundwater gauges met the minimum 8% hydroperiod; successful hydroperiods ranged from 10.6% to 52.8%. Two gauges (no. 3 and no. 5) did not meet the success criteria. The on-site rain gauge experienced above average rainfall every month this year with the exception of February. It is expected the Site will continue to recharge groundwater. Eight CVS vegetation plots and eight random strip plots have been established to monitor vegetation success. The random strip plot totals include planted and volunteer hardwood trees. Seven of the CVS vegetation plots met success criteria of 320 planted stems/acre. Vegetation plot 7 (VP7) did not meet the success criteria with the inclusion of planted and volunteer specimens. The planted densities ranaed from 283 to 931 stems per acre. Seven of the eight random plots met the MY3 Draft Monitoring Report Year 3 (2017) Page 2 Watts Site, Perquimans County, NC Prepared by Ecological Engineering, LLP November 2017 success criteria; the densities ranged from 90 to 648 stems per acre. Areas with thicker herbaceous vegetation had lower stem densities across the site. A few stems of Bradford pear (Pyrus calleryana) were noted throughout the site but are not widespread. 2.0 METHODOLGY Vegetation plot monitoring data were collected following the standard CVS-EEP Protocol for Recording Vegetation, Level 11, Version 4.2 (Lee et al. 2008). Strip plot data was collected in 25m X 4m plots spaced at random throughout the site. The rain gauge, groundwater gauges and pressure transducers are monitored quarterly. Rain data from the CRONOS website, gauge KECG, was used for the months of June, July, and August. The on-site rain gauge was clogged during the month of June and was corrected during the August 16, 2016 site visit. The remaining months utilized the on- site rain data. Information for the CCPV was collected using a Garmin GPS. 3.0 REFERENCES Lee, Michael T., Peet, Robert K., Steven D., Wentworth, Thomas R. 2008.
