SECRETARY January 4, 2011 U.S. Army Corps of Engineers Raleigh Regulatory Field Office 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 Attention: Mr. Eric Alsmeyer NCDOT Coordinator ®®38 Subject: Removal of riser and pipe structure along dam at temporary silt basin associated with previously constructed Nor-them Wake Expressway (part of R-2000EA) and stabilization of downstream streambed and streambanks in Wake County. Note: R-2000EA had USACE Action ID No. 199700884 Lv j e's -14S. tog Z 31 B The North Carolina Department of Transportation (NCDOT) constructed a portion of the Northern Wake Expressway near Falls of the Neuse Road (R-2000EA) in Wake County from 1999-2002. A large temporary silt basin (with riser, dam, pipe structure and overflow ditch) was constructed to the north of the Falls of the Neuse Road on-ramp to I-540. This area was depicted on roadway plan sheet 5. Construction of the temporary silt basin (under R-2000EA) resulted in fill impacts to wetlands and streams at Site 1 as depicted on permit drawings 63 and 63A of 179. For some reason that is unknown at this time, the temporary silt basin was not removed prior to completion of R-2000EA. An adjacent property owner recently contacted the Department about this feature, indicating that the earthen dam was failing. A recent evaluation of the site confirmed that the dam has almost breached, the riser is beyond repair and the entire area needs immediate repair. The Wake County Maintenance Office has determined to conduct the following: 1) Repair small damaged portion of back slope of dam with soil and Class II rip rap; 2) Breach center portion of dam to remove riser and associated pipe structure; 3) Stabilze breached center portion of dam with Class II rip rap; and 4) Construct a lateral base ditch (variable width) lined with Class Il rip rap between the outlet of the pipe structure at dam and the existing pipe structure under Barton's Creek Road. Note that the R-2000EA project has been completely closed out by the NCDOT and these activities are considered as routine maintenance repair. The stream channel currently located between the outlet of the pipe structure under the dam and more recent pipe structure under Barton's Creek Road is highly degraded, full of Division Five- 2612 North Duke Street, Durham, North Carolina 27704 Telephone: 919-220-4600 Fax_ 919-560-3371 L 2 rip rap, steep and unstable.

List the total estimated acreage of all existing wetlands on the property: 0.00 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: There is 70 linear feet of highly degraded stream channel that remains between outlet of pipe structure at dam and inlet of existing pipe structure under Barton's Creek Road. 3d. Explain the purpose of the proposed project: Construction of this section of the Northern Wake Expressway (R-2000EA) occurred between 1999 and 2002. A large temporary silt basin (with a dam, riser and pipe structure) was constructed at this location. For some reason that is unknown at this time, this large feature was not removed prior to completion of R-2000EA. An adjacent property owner recently contacted the Department about this feature, indicating that the dam was failing. A recent evaluation of the site confirmed that the dam has almost breached and needs immediate repair. 3e.

Comments: Riparian buffer impacts located inside the Temporary Drainage Easement (TDE) as depicted on the attached plan sheet occurred during the 1999-2002 construction of R-2000EA and were apparently "grandfathered" due to the status of project design during initial implementation of the Neuse Buffer Rules. The riparian buffer impacts listed in this table only extend from the limits of the existing temporary silt basin (including dam and overflow ditch) to the existing trasnportation facility limits along Barton's Creek Road. These impacts are required to stabilize the stream channel in this area. D. Impact Justification and Mitigation 1. Avoidance and Minimization 1a.
