Re: Status of Green Oaks Parkway compliance and modification request, Holly
Springs, Wake County, NC
Dear Mrs. Keefer:
The purpose of this letter is to provide an update as to the status of the permit
modification request and the efforts being made to bring the Green Oaks Parkway project
back into compliance with 401 and 404 permits issued in November of 2006. The table
below lists the approved impacts as well as what will be requested as an additional
impact within the next week. Please note that the Crossing numbers begin with #1 located
just south of the intersection of Green Oaks Parkway and New Hill Road and continue
through crossing #7 south to the intersection of Green Oaks Parkway and Premier Drive.

Please see the attached maps for a visual representation of the permitted impacts
compared to the current field conditions and soon to be requested modifications. This is a
preliminary draft of the impact table that will be finalized next week and provided to you
within the formal modification and restoration request. Your office previously reviewed a
draft copy of the restoration plan and a final copy will be incorporated within the PCN
submittal next week.
Please call if you have any questions or require further explanation.
Sincerely,
