On June 3, 2008, Mr. Eric Kulz and I conducted an inspection of the mitigation project at the
subject site. The area inspected was that of the stream restoration conducted in the bottomland/flood
plain of the South Fork Catawba River. In general, the stream restoration appeared to be functioning.
However, the following observations were made:
1) The structures (cross vanes) at the beginning of the reach need to be enhanced. There
are several gaps between the boulders that should be closed/minimized. Should the
fabric that currently covers the gaps gives way or tears, the stability of the structure may
be undermined.
2) Stream flow appeared to be eroding the soil behind the root wads. This area needs to
be observed and any repairs made as necessary.
3) The channel has sections of "consolidated" clay as the substrate. On the surface, these
sections are creating grade controls and riffles. However, the riffles and apparent grade
controls are a function of the erosion of these areas. These areas should be under
observation to determine if the erosion of these "consolidated" clay areas adds to the
instability of the channel.
4) More plantings along the channel appeared to be needed to fill out the required fifty-foot
(50 ft.) wooded buffer.
5) The major concern is the step down of the restored channel to the South Fork
Catawba River, which was not functioning. Stream flow was going through the
rocks/boulders as it flowed into the river. Cross vanes such as those constructed at the
beginning of the reach should be utilized. The step down should begin a little sooner
than was observed (as discussed at the site).
