The replaceznent of �e existing bridge with the proposed new bridge will zequire
tert�parary dewatering during abuttnent removal and riprap installation. An irnpervio�s
dike will be constructed adjacent to the propased impaci area to isolate the work area.
Any dirty water Iocated inside the construction area will be pumped into a silt bag if
necessary. Once thE new bank stabilization is in place, the impervious dikes will k�e
removed and preconshuction streambed elevations wi11 be restored.
Constructian of ihis project wi�l r�quire impacts to waters of the United States in the
Watauga River Basin. The existing bridge crosses Curtis Creek (C�ass: C, Trout) and is
located in a trout watershed. This praject does not drain to designated critical habitat.
This project was reviewed for the presence of threatened ar�d endangered species in the
field at�d I have also includec� a query of the NCNHP database. Based on the project area
map�ed with my rec�uest, the database search indicates that there are na recards for
threatened or endangered species, important nahzral cornmunities, ziatural areas, ar
conservation/mar�aged areas within the praposed project boundary. There will be
approximately 0.02 acres of tree cutting at the project location due to cut and fill work.
The NLEB is Zisted as a protected species in this county and the project does fa1l within
one of the HUCs identified in the SLOPES spelled out in the Nationwide Permit Regional
Conditions. We do not anticipate any impact ta any other %derally listed species.
Cu�tural resource compliance work has been completed. No archaeological resources or
histonEc properties wi�l be affected hy this project (see attached).
The pxoject impacts are not si�ruficant in nature and shauld not remove or degrade
existing water quality uses. Stormwater will be routed through grass or rock iined
ditches, depending on the ditch line slope. Pipe sizes used will be fihe minimurn
necessary to create a safe raadway. By utilizing t1�e erosion control measures outlined in
the attachtr�ents to this application, downstream watcr quality standards will be protected.
AlZ appropriat� BMPs wi�i be used during construction.
By copy of this electronic letter, it is rec�uested that Mrs. Marla Chambers with the North
Carolina Wildlife Resources Commission coznment direct�y to you concerning the 404
Nationw�ide Permit application with a copy sent to me.
By copy of this eZecfironic letter, it is request�d that the Division of Water Resonrces,
4411Wetlands Unit, issue the appropriate permit f�r construction of tlus project. It is
requested that axiy comments related to the 401 certification be electronically farwarded
direc�ly to me with a copy sent ta tkze US Army Co�ps of Engineers.
We would like to begin construction as soon as possibie. If further information is
required, please iet me know. Your eaxly review and consideration will be appreciated.
