Project Status: Complete
Monitoring Level required by COE and DWQ (404 permit/ 401 Cert.): Level -
Monitoring Level 1 requires completion ofSection 1, Section 2 and Section 3
Permit States: The permittee will visually monitor the vegetative plantings on all mitigation
streambanks to access and insure complete stabilization of the mitigation stream segments. This
monitoring will include adequate visual monitoring of planted vegetation for a minimum of one
year after final planting, and appropriate remedial actions (e.g., replanting, streambank grading,
ect.). If within any monitoring year, bank stabilization is not acceptable as determined by the
Corps of Engineers, and remedial action required by the Corps of Engineers is performed, the
two year monitoring of the affected portions of the stream will begin again.
Section 1. PHOTO REFERENCE SITES
Total number of reference photo locations at this site:
4 photo point locations - 2 photos at each location
Dates reference photos have been taken at this site: 5/10/06, 8/22/06,11/15/06,1/31/07
Individual from whom additional photos can be obtained (name, address, phone):
Other Information relative to site photo reference:
If required to complete Level 3 monitoring only stop here; otherwise,
Section 2. PLANT SURVIVAL
Attach plan sheet indicating reference photos.
Identify specific problem areas (missing, stressed, damaged or dead plantings):
A rainfall event of approximately 7 inches (Tropical Storm Alberto. June 2006) occurred shortly after construction.
Some of the planted vegetation was washed away during this event.
Estimated causes, and proposed/required remedial action:
Live stakes and bareroot seedlings were installed on 1/31/07 to replace the planted vegetation that was washed away
after initial planting took place on March/April 2006.
ADDITIONAL COMMENTS: Vegetation is dormant for the 4th Quarter of monitoring. Live stakes
and bareroot seedlings noted on the streambank and in the floodplain consisted of black willow, silky dogwood,
green ash, swamp chestnut oak, willow oak, and laurel oak.
If required to complete Level 1 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/morphology 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 4th Ouarter monitorine evaluation was conducted on Januarv 31. 2007. A rainfall event of approximately 7
inches (Tropical Storm Alberto, June 2006) occurred shortly after construction. Some of the planted vegetation was
washed away during this event. Replanting of live stakes and bareroot seedlings took place on January 31. 2007.
Localized bank erosion and erosion behind some of the cross vane arms was still noted during this monitoring
evaluation. Point bars have developed where the banks have eroded helping the stability of the stream. Deposition
has occurred behind some of the exposed cross vane arms. NCDOT will continue to monitor this stream.

NOTE: Attach separate narrative sheets to each monitoring report describing/discussing the
overall monitoring results. Include the identification of specific problem areas/channel failures,
estimated cause and proposed/required remedial action. This should include a brief discussion of
any parameter that has changed significantly from as-built.
