Date Construction Completed: Streambank reforestation completed on March 1, 2018 Monitoring Year: ( 4 ) of 5 Ecoregion: Southern Outer Piedmont 8 digit HUC unit 03040101 USGS Quad Name and Coordinates: Winston-Salem East 36.100238°,-80.135216' Rosgen Classification: Length of Project: 490 linear feet Urban or Rural: Rural Watershed Size: 0.14 sq. miles Monitoring DATA collected by: M. Green and M. Ingram Date: 9-23-21 Applicant Information: Name: NCDOT Roadside Environmental Unit Address: 1425 Rock Quarry Road Raleigh, NC 27610 Telephone Number: (919) 615-6733 Email address: ml rgreen&ncdot.gov Consultant Information: Name: Address: Telephone Number: Email address: Project Status: Complete Monitoring Level required by COE and DWR (404 permit/ 401 Cert.): Level Mitigation Plan States 5.0 Performance Standards Success for vegetation monitoring within the riparian buffer areas are based on the survival of at least 260 stems of five -year -old trees at year five. Assessment of channel stability will be based on the survival of riparian vegetation and lack of bank erosion, channel widening or down -cutting. 6.0 Monitoring Requirements All the mitigation sites will be monitored according to the April 2003 Stream Mitigation Guidelines. The following components of Level 1 monitoring will be performed each year of the 5-year monitoring period: reference photos, plant survival (i.e., identify specific problem areas (missing, stressed, damaged or dead plantings), estimated causes and proposed/required remedial action; visual inspection of channel stability. Physical measurements of channel stability/morphology will not be performed. A monitoring report will be submitted within 60 days after completing the monitoring. Section 1. PHOTO REFERENCE SITES (Monitoring at all levels must complete this section) Total number of reference photo locations at this site: A total of 6 photos were taken from 3 photo point locations and 1 additional overview photo of the site. Dates reference photos have been taken at this site: 8-14-18, 8-29-19, 8-25-20, 9-23-21 Individual from whom additional photos can be obtained (name, address, phone): Other Information relative to site photo reference: A site map is included with this report showing the Section 2. PLANT SURVIVAL Attach plan sheet indicating reference photos. Identify specific problem areas (missing, stressed, damaged or dead plantings): Estimated causes, and proposed/required remedial action: ADDITIONAL COMMENTS: March 2018: Streambank reforestation was completed August 2018: Year 1 Monitoring noted Black Willow and Silky gwood live stakes were surviving along the streambank. The site has 680 trees per acre surviving for Year 1. August 2019: Year 2 Monitoring noted Black Willow and Silky Dogwood live stakes were surviving along the streambank. The site has 680 trees per acre surviving for Year 2. August 2020: Year 3 monitoringnoted oted planted vegetation survival was good, except for, the areas noted above. Vegetation Plot #1 had 663 trees per acre surviving for Year 3. October 2020: Regulatory Agency review held onsite with NCDOT January 2021: Supplemental planting September 2021: Year 4 monitoring noted live stakes were surviving and Vegetation Plot #1 had 680 trees per acre surviving for Year 4. Other vegetation noted onsite included volunteer sycamore, maple, sweetgum, tulip poplar, black walnut and various grasses. NCDOT will continue to monitor the planted vegetation in 2022. If required to complete Level 1 and Level 2 monitoring only stop here; otherwise, complete section 3.

CHANNEL STABILITY Visual Inspection: The entire stream project as well as each in -stream structure and bank stabilization/revetment structure must be evaluated and problems addressed. Report on the visual inspection of channel stability. Physical measurements of channel stability. /orphology will not be required. Include a discussion of any deviations from as -built and an evaluation of the significance of these deviations and whether they are indicative of a stabilizing or destabilizing situation. The UT to Fisher Branch onsite stream mitigation site is stable for the Year 4 evaluation from just downstream of PP#1 to the inlet of the box culvert. There are portions of the stream from the beginning of the site to just downstream of PP#1 where the banks are eroding and sloughing off. Some sections of the channel have started to form a new bankfull bench and are stabilizing. This area shows little to no change over the past year. A supplemental planting with live stakes was completed in January 2021 to help stabilize these areas. NCDOT will continue to monitor channel stability at the UT to Fisher Branch Mitigation Site in 2022.

DEBIT LEDGER The entire UT to Fisher Branch stream mitigation site was used at a 1:1 ratio for the U-2579B project to compensate for unavoidable stream impacts.
