For question 1: There will 600 sg ft of zone 1 impacts for ipe and 400 sq
ft of zone 2 impacts for each pipe. The way I figured it, is that we are adding
ten linear of pipe to each stream and these pipes have head walls so the
additional fill materal in the buffers will not extend beyond headwalls.
Therefore 10 linear feet X 50 foot of buffer = 500 sq ft X 2 sides of stream
= 1000 sq ft (600 zone I and 400 zone 2) per pipe.
thanks,
Chad C.

Chad will give you the breakdown for each site.
For question 2: The wetlands are just off the R/W at station 24+51. - I made
the notation on the plans to emphasize to t e~T coon factor not to kick the
ditches out from the current location. Originally the plans showed a rock
silt check dam and the back ditch moved out, but we were able to minimize it
in order prevent impact on the wetlands. The culvert in the area will have
aluminum headwalls so that we wouldn't need any additional fill.

Jamie,
I'm reviewing this application today and have a couple of questions that
need clarification:
1- For which site are the buffer impacts for? If both, can you break it
down for the two sites please?
2- At station 24+51, the plans show wetlands on the west side of the
road. (A notation directs the contractor to not put erosion control
devices there.) What I'm wondering is if the road & shoulder widening
wouldn't impact any of these wetlands? The drawing kind of looks to me
like the wetlands are right up against the current road....therefore any
widening would result in some fill? In which case we should account for
those so that you can get approval in your 401 for it.
Thanks,
I Rob
