Columbus County State Project Number: 6C.024071 The North Carolina Department of Transportation (NCDOT) has scheduled to grade, drain, base and pave SR-1561, in Columbus County. Total project length is 0.89 mile. The roadway will be widened from 16 feet to 20 feet and stabilized grass shoulders (6 foot) will be provided. This project will require the replacement of one (1) wet cross line as shown below: Crossin Roadwa Station Existin Culvert Pro osed Culvert Crossing #1 Sta. 38+90 (2) 44 LF 48" RCP (2) 50 LF 48" RCP New stream impacts = 6 linear feet Construction of this project will require impacts to waters of the United States in the Lumber River Basin. Crossing #1 will convey an UT to Dunn Swamp (C; Sw). This project is located in the Hydrologic Unit 03040203 Subbasin 03-07-51. Culvert #1 conveys an UT to Dunn Swamp (C; Sw) from a forested wetland/agricultural area. This crossing has undergone human manipulation and exhibits year round flow. The existing twin 44 LF 48" RCP has signs of joint failure and deterioration. The culvert will be replaced with twin 50 LF 48" RCP. The increase in size and length will accommodate aquatic life movements and provide a more efficient culvert entrance. This culvert will be buried 10 inches. P. O. Box 1150, Fayetteville, NC 28302-1150 -Telephone (910) 437-0208- Fax (910) 486-1959 RESOURCE STATUS In general, there will be minor impacts proposed as a result of the replacement of culverts along SR-1561 in Columbus County. Six (6) linear feet of stream impacts are expected. A Nationwide Permit #14 /NCDENR 401 WQC 3404 is required for the project. Endangered Species: Plants and animals with Federal classification of Endangered (E) or Threatened (T) are protected under provisions of Section 7 and Section 9 of the Endangered Species Act of 1973, as amended. As of January 29, 2004, the U.S. Fish and Wildlife Service lists five federally protected species for Columbus County. Federally Protected Species for Columbus County SCIENTIFIC NAME COMMON NAME STATUS Acipenser brevirostrum Shortnose Sturgeon E Picoides borealis Red-cockaded woodpecker E Menidia extensa Waccamaw Silverside T Thalictrum cooleyi Cooley's meadowrue E Lysimachia as erulaefolia Rough-leaved loosestife E "E" denotes endangered (a species that is in danger of extinction throughout all or a significant portion of its range). T(S/A)- Threatened due to similarity of appearance, a species that is threatened Due to similarity of appearance with other rare species and is listed for its Protection. These species are not biologically endangered or threatened and Are not subject to Section 7 consultation. A biological conclusion of "No Effect" was reached for all species during the May 23, 2006 survey for protected species. Protected species were not identified, nor, was the general habitat for each species identified. REGULATORY APPROVALS Application is hereby made for a Department of the Army Nationwide Permit 14 /NCDENR 401 WQC 3404 as required by the above-described activities. The National Register was reviewed in addition to conducting a field view of the project for significant historic features. The project impacts are minor in nature and should not remove or degrade existing water quality uses. Pipe sizes proposed should address most flooding concerns, but they will not eliminate the potential to flood. All appropriate Best Management Practices will be utilized during the construction of this project. Attached is a Preconstruction Notification Form, plan sheets, marked county road map, quad location map and photographs.

Surrounding land use is agriculture/forested. 10. Describe the overall project in detail, including the type of equipment to be used. In bringing SR-1561 (Moccasin Pond Rd.) up to current safety standards, i.e. 20 foot paving w /6 foot stabilized shoulders and 3:1 side slopes within a 60 foot right-of--way, NCDOT must impact upon 6 linear feet of UT to Dunn Swamp. The existing culverts are severely deteriorated with joint failures and .must be replaced. Impacts were minimized as much as possible; 3:1 side slopes are required due to the sandy material Page 6 of 12 found in the area and the inability to stabilize such material. The culverts will be replaced utilizing atrack-hoe excavator. While front end loaders will place material. Eventually, a motor grader will finish grade the project prior to paving. 11. Explain the purpose of the proposed work: By Statue, NCDOT is required to pave all unpaved Secondary Roads.
