The Corps accepts the changes discussed in the field and recorded on these revised plan
sheets.
Also as discussed yesterday we are interested in seeing the turbidity level at the mixing
zone of the known jurisdictional feature. This will help in determining if more measures
are needed to control off site sedimentation.
Thanks,
Brad

Subject: [Non-DoD Source] U-4751 Site 36 TS Impacts
As we discussed and reviewed yesterday at Site 36 on U-4751, there was a jurisdictional
feature near the tie in of the R-3300 project that was not identified on the U-4751
permit drawings or erosion control plans as a jurisdictional feature. This error was
discovered when I was onsite with the project inspector and contractor several week
ago to discuss concerns with the the diversion channel for Site 36.
The erosion control plans showed us installing a sediment basin in this feature, which is
identified in the PJD as feature FSJ. Prior to my meeting to discuss the diversion
channel, the project inspector had gotten approval from Roadside, to just install a check
dam and baffles in this feature, in lieu of excavating the proposed basin.
In our review of the site yesterday we verified that this feature is a tributary and the
erosion control measures are warranted. The attached drawing shows the feature
which we identified as a JS non-mit feature and the location of the TS impacts for the EC
BMP's. The TS impacts for this site was calculated to be 60 sq. ft. and does not change
the overall permitted TS impacts for this project.
Please accept the attached permit drawing as a record for your files documenting these
new TS impacts. If you have any questions or require any additional information, please
feel free to contact me.
Thanks!
