Ian:
Larry looked over this project, and I have looked at it too. According to BIMS,
this has not been issued yet. There are some very strange things in the design
documents, including, but not limited to: The existing stream and proposed restored
reach are both B4c, but the refernece reach is a C4. This appears to be a Priority
I restoration; however the proposed entrenchment ratio (1.8) does not differ
significantly from the existing ration (1.4). the reference is 12.4. The proposed
bankfull cross-sectional area is larger than the existing; this is odd, as impacted
streams are usually overwidened. Which brings up another point; there is very
little discussion of the existing site conditions.
The strangest thing is that the existing sinuosity is 1.15, and so is the sinuosity
of the proposed reach!!
There are other things as well.
The box on public funds was checked "yes". Why no NEPA/SEPA?
Does anyone know if they are doing this for mitigation credit?? the PCN does not
say. Also, the total length of the restoration reach is not clear.
Darryl, are you familiar with this project?
