EASLEY DNISION OF HIGHWAYS LYNDO TIPPETT GOVERNOR SECRETARY Apri14, 2007 Mr. John Hennessy 401/Transportation Permitting Unit O ~ ®~ 1650 Mail Service Center 1 Raleigh, N.C. 27699-1650 SUBJECT: Pipe replacement on SR 2003 (Bridges Circle Road), Cleveland County Dear Mr. Hennessy: The North Carolina Department of Transportation proposes to replace a deteriorating pipe on SR 2003 (Bridges Circle Road) in Cleveland County. A 57.5-foot, 72" CMP will be replaced with a 60-foot, 90" CMP with inlet headwall and associated riprap for structure protection. A shallow scourhole is located at the existing pipe outlet and the channel is overwidened to a width of ~10 feet. A 15-foot long, rock-faced floodplain bench will be constructed at the new pipe outlet to narrow the channel dimension to a normal channel width of 5 feet, based upon a reference upstream cross-section. The new pipe will be placed on approximately a 3.3% slope; therefore, rock will be embedded into the stream channel at the new pipe outlet for a distance of ~10 feet in an effort to prevent future stream destabilization. Temporary cofferdams and bypass piping will be utilized for stream management during the pipe replacement. The scope of the work will result in a total of 17.5 feet of permanent impacts and ~80 feet of temporary impacts to an unnamed tributary to the Muddy Fork, which is classified as Class C waters by the Division of Water Quality. Upon project completion, the area impacted by the temporary cofferdam will be restored to pre-project conditions. The project is not located within '/z mile of any critical watershed area nor is SR 2003 a rural or urban arterial; therefore, hazardous spill basins are not required. Enclosed is the hazardous spill basin checklist. This office has conducted a GIS and field survey for the project for historical sites and threatened/endangered species sites. No sites listed on the National Register of Historic Places are located in the vicinity of the project nor did there appear to be any eligible structures. 1 SR 2003, Bridges Circle Road Page 2 Apri14, 2007 The federally listed species for Cleveland County (USFWS listed dated December 11, 2006) include the dwarf-flowered heartleaf (Hexastylis nan~ora). Natural Heritage Program records document the nearest dwarf-flowered heartleaf location approximately 4.0 miles northwest of the proposed project area. The heartleaf is usually found on dry to moist ravine slopes (usually north facing and of the oak-hickory-pine forest type) and in boggy areas near springheads. The project area is mostly comprised of young and mature hardwoods with thick understory vegetation. There is little potential habitat within the proposed project area and no species were observed. NCDOT is recommending a finding of "no effect" for T&E species and for historical structures. I have enclosed apre-construction notification for a NW# 14, sketches of planned activities, and location maps relative to the project. Project information for the 401 Automated Payment Procedure is as follows: • Work order number: 15046455120005-12B.202311-3855 • TIP #: NA • Project Category: $200.00 Fee If you have any questions or concerns, please feel free to contact me at (704) 480-9044.

Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Minimal tripe impacts. The presently overwidened channel will be restructured to "normal" channel dimensions based upon an upstream reference cross-section. The new pipe slope will be on 3.3% slope: therefore. the streambed at the outlet will be armored in an effort to prevent future stream destabilization. Page 5 of 8 VIII. Mitigation DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at http://h2o.enr.state.nc.us/ncwetlands/strmgide.html. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. NO MITIGATION ANTICIPATED 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form.

ZONE AH Flood depths of 1 to 3 feet (usually areas of ponding); base flood elevations determined. 20NE AO Flood depths of 1 to 3 feet (usually sheet flow on sloping terrain); average depths determined. For areas of alluvial fan flooding, velocities also determined. ZONE A99 To be protected from 100-year Flood by Federal flood protection system under construction; no base elevations determined. ZONE V Coastal Flood with velocity hazard (wave action); no base flood elevations determined. ZONE VE Coastal flood with velocity hazard (wave adion); base flood elevations determined. ® FLOODWAY AREAS IN ZONE AE OTHER FLOOD AREAS ZONE X Areas of 500-year flood; areas of 100-year flood with average depths of less than 1 foot or with drainage areas less than 1 square mile; and areas protected by levees from 100-year flood. OTHER AREAS ZONE X Areas determined to be outside 500-year flood plain. ZONED Areas in which flood hazards are undetermined.

Areas of Special Flood Hazard (100-year flood) include zones, A, AE, Ai-A30, AH, AO, A99, V, VE and Vl-V30. Certain arras not in Special Flood Hazard Areas may be protected by flood control structures. Boundaries of the floodways were computed at cross sections and interpolated between ~:ross sections. The floodways were based on hydraulic considerations with regard to requirements of the Federal Emergency Management Agency. Floodway widths in some areas may be too narrow to show to scale. Refer to Floodway Data Table where Floodway width is shown at 1/20 inch. Coastal base flood elevations apply only landward of the shoreline. This map incorporates approximate boundaries of coastal barriers established under the Coastal Barrier Resources Act (PL 97-348). Corporate limits shown are current as of the date of this map. The user should contact appropriate community officials to determine if corporate limits have changed subsequent to the issuance of this map.
