The SFRS is a riparian system in the Upper Neuse River Basin (03020201 8-digit cataloging unit) in Johnston County, North Carolina. The site’s natural hydrologic regime had been substantially modified through the relocation and straightening of the existing stream channels, impacted by land clearing, and cleared of any riparian buffer. This completed project will restore impacted agricultural and timber lands to a stable stream ecosystem with a functional riparian buffer and floodplain access. The SFRS is protected by a 24.4 acre permanent conservation easement, held by the State of North Carolina. The site is located approximately 5.5 miles north of Benson, NC. Specifically, the site is 0.2 mile west on Elevation Road from its intersection with Federal Road (SR-1331). The North Carolina Ecosystem Enhancement Program (NCEEP) published the Neuse River Basin Priorities in 2010. These were updated in for the Neuse 01 cataloging unit (CU) in 2015 due to extensive mitigation needs and changes in watershed conditions since 2010. The project 14 digit CU (03020201150010) was identified as a Targeted Local Watershed (TLW) in the updated priorities. The goals and priorities for the SFRS are based on the information presented in the Neuse River Basin Restoration Priorities: maintaining and enhancing water quality, restoring hydrology, and improving fish and wildlife habitat (NCEEP, 2009). The project will support the following basin priorities: - Managing stormwater runoff - Improving/restoring riparian buffers - Reducing sediment loading - Improving stream stability The goals for the project are to: - Restore channelized and agriculture impacted streams to stable C/Cb channels. - Restore a forested riparian buffer to provide bank stability, filtration, and shading. The project goals will be addressed through the following objectives: - Relocate a channelized stream to its historic landscape position. - Install cross-sections sized to the bankfull discharge. - Create bedform diversity with pools, riffles, and habitat structures - Plant the site with native trees and shrubs and an herbaceous seed mix. Project planting and construction were completed in May 2019. The SFRS involved restoration and establishment of a functioning stream ecosystem with 6,810 linear feet of stream restored by re-meandering the stream and by tying the bankfull elevation to the historic floodplain where feasible. The entire site was planted to establish a forested riparian buffer. The site was constructed as designed with no major modifications from the design plan. The monitoring components were installed in May 2019. Four automatically recording pressure transducer stream gauges that take a reading every 10 minutes were installed in the upper third of T1, T1-A, T2 and T3 to document flow within those reaches. Cameras were installed in the vicinity of each of these gauges and set to record a short video once a day to provide additional verification of flow. An additional automatically recording pressure transducer stream gauge was installed near the bottom of the main stem (SF3) to record the occurrence of bankfull events. To determine the success of the planted mitigation areas, seven 10 m x 10 m permanent vegetation monitoring plots were established. An additional five 10 m x 10 m random vegetation monitoring plots were sampled as well. The locations of the planted stems relative to the origin were recorded within the permanent plots and the species and height of each planted stem were recorded for all plots. Any volunteers found within the plots were also grouped into size categories by species, but separate from the planted stems. Twelve permanent photo reference points were established and will be taken annually. Sixteen permanent cross-sections (eight riffle Stony Fork Restoration Site KCI Associates of NC, PA DMS Project # 97085 2 2019-MY01 cross-sections and eight pool cross-sections) were also established and a detailed longitudinal profile of the stream was taken. Wolman pebble counts were performed at all of the riffle cross-sections. The cross- section measurements will be repeated in future monitoring years, but the longitudinal profile will only be repeated if there are concerns about bed elevation adjustments. Reports will be submitted to DMS each year. Vegetative success criteria for the stream mitigation is 260 woody stems/acre after five years, and 210 woody stems/acre after seven years. Trees in each plot must average seven feet in height at Year 5 and ten feet in height at Year 7. Volunteer species must be present for a minimum of two growing seasons and must be a species from the approved planting list to count toward vegetative success. A single species may not account for more than 50% of the required number of stems within any plot. A minimum of four bankfull events must also be recorded during the monitoring period. All project streams must show a minimum of 30 continuous days of flow within a calendar year for three out of the first four years of monitoring. Bank height ratios (BHR) should not exceed 1.2 and the entrenchment ratios (ER) should be 2.2 or greater. BHR and ER at any measured riffle cross-section should not change more than 10% from the baseline condition during any given monitoring interval (e.g. no more than 10% between years 1 and 2, 2 and 3, 3 and 5, or 5 and 7). Visual assessments will also be used to identify problem areas. Vegetative success criteria for the areas proposed for riparian buffer credit is 260 woody stems/acre at the end of five years of monitoring. Trees in each plot must average seven feet in height at Year 5. There should be a minimum of four native hardwood tree species, with no species accounting for greater than 50% of the stems. Volunteer species must be from the approved planting list to count toward vegetative success. MONITORING RESULTS The first-year vegetation monitoring was conducted November 5, 2019. The site averaged 946 planted stems/acre across all 12 plots. All thirteen plots had greater than 260 planted stems/acre. Including volunteers, the site averaged 1,072 total stems/acre. In general the site is well vegetated, with widespread herbaceous coverage and healthy planted stems. The stream gauge near the bottom of SF3 did not record any bankfull events in 2019. All four stream flow gauges recorded at least 30 consecutive days of flow. The gauges on T1 and T1A recorded 60 consecutive days and 182 consecutive days respectively, while the one on T2 recorded 85 days and the one on T3 recorded 55 days. The gauge data was further backed up by the cameras on site. Based on the video recordings obtained from the cameras, T1A had flow for a maximum of 46 consecutive days, T2 had flow for a maximum of 84 consecutive days, and T3 had flow for a maximum of 55 consecutive days. The camera on T1 was obscured by moisture that got inside of the lens for most of the year. The difference in the numbers obtained from the cameras compared to those obtained from the gauge is largely due to the cameras becoming obscured by vegetation, or moisture on the lens for parts of the year. The longitudinal profile was not repeated for the first-year survey because the baseline survey found that the stream was constructed as designed, and there were no concerns about bed elevation adjustments. The first-year cross-section survey found that the dimensions of the stream are as designed, with some small variation as is typical for stream restoration projects. The monitored cross-section data have been calculated by adjusting the bankfull elevation to maintain the baseline bankfull area for each cross-section. o o o ooo o o oo o o o o oooo o o o o o o o o ooo o o o oo o o o o o ooo o o o oooo o o o oo o ooo o ooo o o o o o o o o o o oooo o o oo o oo o o o o o o o o oo o o o o o o o o oooooooo ooo oooooo oooooo oooooooooooooooooooooooooooooooooooooo oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo o oo o o o oo o o o oo o o o o o ooo o oo o oo o o oo o o o o o o oo o o ooo o oooo o o o o oo ooo o o o o o o o o o o ooo o o oo o o o o o o o o o o oo o o o o o o oo o o o o oo o o o o oo o o o o o o o o o o o o o ÊÚ §¨¦40 §¨¦95 50 27 242 242 £¤301 BENSON B l a c k Creek ÊÚ WAKE JOHNSTON WAYNE NASH SAMPSON HARNETT WILSON ÊÚ Project Site Location County Boundary Major Roads Minor Roads o Airports (none within a 5-mi radius) Major Rivers and Streams Cities and Towns Elevation RdFederal RdÜ 0 10.5 Miles FIGURE 1.
