NC Hwy 294 — Cherokee County
Site inspection
On January 27, 2016, I performed a site visit, along with Trent Anderson (NCDOT) in response to the
complaint received from Ms. Doris Stringer and Ms. Sharon L. Rhoton.
The following observations were made:
The culvert under Upper Bear Paw Rd is indeed perched (approx. 18 inches). Observing the asphalt road
way, the condition of the culvert, and having background knowledge of the area, this culvert was installed
in excess of 15 years ago. The aquatic life passage issue will be addressed at the next culvert replacement
interval.

The stream below the perched culvert is devoid of foreign material, with natural bed material present
through out the reach.

The stream reach (in excess of 100 linear feet, is devoid of best management practices (such as vegetated
buffers) and exibits lateral stability issues. This area, immediately below the perched culvert brought up
in the complaint, is far outside the work area of the DOT, and I do not believe the DOT has any plans to
work in this area.

The stream immediately below the DOT installed bypass pipe (necessary for culvert replacement currently
underway) did have an insignificant amount of crushed rock (gravel) present in the stream bed. DOT has
agr�ed to remove this material at the end of construction via manual labor (bucket anti shovel) down to
the natural stream bed.

The stream immediately above the complainant's driveway culvert had a very small amount of gravel in
the channel. This amount does not reduce the cross-sectional width of the channel and is not restricting
flow in any measurable matter. Immediately below the complainant's driveway culvert, there was
observed bank instability and the formation of a mid-channel bar of mixed material (gravel and
sediments). DOT agreed to remove the few buckets ofgravel above the culvert and rake back the material
immediately below the culvert to re-establish the thalweg.

of the storm events that occurred in the area at the end of December / beginning of lanuary. It was
documented that in excess of 15 inches of rain fell within a weeks time. This resultPd in a significant "out
ef bank" event above #he road work occurring, as well as the compiainants documented experiences.

It was not observed that any of the DOT's actions taken changed the hydrology of the event experienced
DOT did have Hydraulic Engineers frorn Raleigh look at this situation durong the month of January w9th no
recommended changes to the project. The DOT has agreed that as soon as the construction is completed
at this site (approx 30 days out), that all remedial actions will be taken and a follow up inspection by DOT
and DWR will occur at that time
