Attention: Mr. Steve Lund, MS, PWS

Subject: Request for Permit Modification - USACE Action ID: SAW-2008-0086-360
U-5025 (MAI0181R), Weddington Road (SR 3468) from north of 1-485 to the
intersection of Pleasant Plains Road (SR 3448), Mecklenburg County.
WBS Element Number 37162 (DWQ Minor Permit Fee $200.00).
Dear Mr. Lund:
In an application dated December 17, 2007 the North Carolina Department of Transportation
(NCDOT) proposed to widen Weddington Road in Mecklenburg County from north of I-485 to
the intersection of Pleasant Plains Road. At that time the NCDOT requested a permit
authorization to replace the existing 7.3 foot x 6.5 foot x 110 foot long culvert with a 12 foot by
9 foot x 143 foot long pre-cast culvert. The total length of the proposed impacts for the project
was stated to be 101 feet which included bank stabilization activities.
It has recently come to our attention that the existing 30 inch by 75 foot long culvert located at
Sta. 58+00 needs to be upgraded to a 48 inch by 116 foot long reinforced concrete pipe. If
authorized, impacts will be incurred to an unnamed intermittent stream that flows to Four Mile
Creek in the Catawba River Basin (Hydrologic Unit: 03050103). The total length of new impact
would not to exceed 45 linear feet.
The purpose of this letter is to request a modification to the previously issued 404 Nationwide
Permit (USACE Action ID: SAW-2008-0086-360) that would authorize 45 feet of intermittent
stream impact to an unnamed tributary of Four Mile Creek located at Sta. 58+00 of the attached
plan. A request is also being made to the North Carolina Division of Water Quality for a permit
modification to the previously issued 401 Water Quality Certification (DWQ# 07-2175) for the
same.
If you should have any questions regarding this request, please contact Mr. Larry Thompson,
Division Environmental Supervisor at [e-mail] or [phone]. 19
