I looked over the stream restoration plans. The basic idea that they are employing is to copy the existing stream channel
to essentially repair as opposed to restore the channel. The two reaches are relatively short so a full restoration may not
make sense anyway. They do not appear to have taken all of the steps needed to provide a naturally stable stream
design, but they have added several grade control structures to attempt to provide stream bed and bank stability. The
structures should also provide habitat in the form of riffles and pools.
It is not clear if the design will be stable, but the reasoning behind their approach makes sense, as long as the portion of
the stream on which they based their design is stable.
