John,
I think you've got everything that we talked about. I just wanted to add that the
addition of the buffer impacts from the bypass channels associated with future
phases will mean that you have to submit a revised PCN indicating total buffer
impacts and additional impact maps of those not already submitted.

Annette and Joseph,
Based upon our conversation today, we have agreed to provide the following:
1) For the wetland bypass channels, we currently we are showing the impacts for
the permanent wetlands and not the wetlands for the future phases. We will
provide the impacts due to the bypass channels for all of the wetlands, including
those in future phases.
2) We will show the longitudinal slopes on the plans for the wetlands which we
have designed.
3) We will show the vegetation zones in the wetland per the newest BMP Manual.
4) We will revise the channel dimensions on Sheet C458.
5) We will add a note regarding the cleared area for the bypass channels. It will
state that grass will be sewn immediately upon completion of construction of each
channel.
Also, as to the letter you requested from DOT stating that it meets all safety
requirements, the road will be a City road and not NC DOT. The sides of the road
in the area will be fenced and there will be 14-feet from the back of curb to
the beginning of the wetland side slopes. City of Durham Engineering is in the
process of approving the Construction Documents, which show the wetlands located
as they are. By approving the Construction Documents, they are implicitly
approving the locations of the wetlands for safety purposes. However, we have
attempted to get the City to provide a letter and, given it is something that
don't normally do, they have been reluctant to provide it.
We will be providing the above information to you no later than next Friday, May
30"th . Don't hesitate to give me a call should you have any additional
questions.
Thanks,
JOHN SCHRUM
