Urban or Rural: Urban Watershed Size: 0.26 sq. miles Monitoring DATA collected by: M. Green and M. Ingram Date: 8-25-20 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 II Restoration Plan States: NCDOT will visually monitor using Level II monitoring (i.e. vegetation success and stability). We will initiate twice yearly visual monitoring for stability and percent vegetative cover for one year after the water is released into the newly restored channels. 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 10 photos were taken from 5 photo point locations and 1 additional overview photo of the site. Dates reference photos have been taken at this site: 8-29-19, 8-25-20 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 photo point locations. 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 2019: Streambank reforestation was completed August 2019: Year 1 Monitoring noted Black Willow and Silky Dogwood live stakes were surviving aloniz the streambank and Green Ash, Sycamore, Willow Oak, Water Oak and River Birch trees were surviving within the planted buffer. August 2020: Year 2 Monitoring noted Black Willow and Silky Dogwood live stakes were surviving along the streambank and Green Ash, Sycamore, Willow Oak, Water Oak and River Birch trees were surviving within the planted buffer. Other vegetation noted included lespedeza, jewelweed, cattails, soft rush, red maple, goldenrod, fennel, briars, elderberry,woolgrass, tulip poplar, and various grasses. NCDOT proposes to discontinue monitoring the planted vegetation. If required to complete Level I and Level 2 monitoring only stop here; otherwise, complete section 3. 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. Sites 3A and 313 temporary impact streams are stable for the Year 2 evaluation. No instability was noted along the streams. A wrack line was visible within the floodplain indicating a bankfull event had occurred. NCDOT proposes to discontinue monitoring channel stability at the Sites 3A and 3B temporM impact streams. Date Station Station Station Station Station Inspected Number Number Number Number Number Structure Type Is water piping through or around structure? Head cut or down cut resent? Bank or scour erosion resent? Other problems noted? Bankfull 8-25-20 event Section 4.DEBIT LEDGER The restoration of Sites 3A and 3B was used entirely to compensate for temporary impacts on the U-2579B project. There were no stream mitigation credits generated from the restoration of the impacted area.
