Yes, correct- at that Impact Area 1. Will get those impacts for you. Thanks-

So the actual loss of stream is 157, even though the pipe is 96 ft. part of the old channel is lost due to the location of
the new pipe. So the riprap extending from the new pipe is on upland.

Need the buffer impacts temporary/permanent (total)
And amount within 50 ft (if any)

Hey Alan-

Working on these comments here. Just wanted to clarify, on the rip rap at Impact Area 1, that rip rap isn't being
installed within the existing channel. That rip rap is being placed at the outfall of the proposed culvert at a location of
an approximate 20LF channel that will tie-in to the existing stream. That is why we didn't count the rip rap here. At
Impact Area 2, it is being installed within the existing channel so we included there. Make sense?

it didn’t.

No they don’t have to bore all the way, but because they are submitting the 401, the impact should be
included. Meet the condition of the buffer rule. I would bore outside of 50 ft from top of bank.

With the new regional conditions the USACE is calling rip rap that is installed at grade (not piled up) as a permanent
impact but not a loss that requires mitigation - the engineers design the length of these rip rap aprons based on
engineering and local criteria. We certainly can have them provide the calcs and the standards.

I included Heath on your boring concern because he met with you regarding this ... can we discuss with him too. Do
they need to bore all the way?

A tad confusing: on stream A, you combine the riprap and pipe for a total of 157 ft of impact (states 96 ft of culvert,
so that means 60 ft of riprap???) sound like a lot.

On stream C you split the impact out. 32 ft of riprap 61 ft of culvert

Are they jack and boring through/under the entire buffer? IF not, the impact should be called out in the buffer impact
table. Clarifying permanent and temporary impact.

Thanks
