EASLEY DIVISION OF HIGHWAYS LYNDO TIPPETT GOVERNOR SECRETARY August 27, 2007 Mr. Steve Lund US Army Corp of Engineers Asheville Regulatory Field Office O ~ l 151 Patton Avenue, Room 208 .i Asheville, N. C. 28801-5006 SUBJECT: Secondary Road Paving/Pipe replacement, SR 1824 (Hatcher Spangler Road), Cleveland County Dear Mr. Lund: The North Carolina Department of Transportation proposes to replace a pipe in conjunction with a secondary road paving project on SR 1824 (Hatcher Spangler Road) in Cleveland County. The existing 36-foot, 24" CMP, which is on a ~7.4% slope) will be replaced with a 70-foot, 30" HDPE, placed on ~3% slope. The new pipe will be placed on a skew to better align the upstream and downstream sections, which will result in the loss of 42 linear feet of stream length. The existing pipe inlet is on streambed grade and the outlet is perched. The new pipe inlet will also be placed on streambed grade in an effort to prevent headcutting and the new pipe outlet will also be perched; however a 10-foot rock ladder will be constructed at the new pipe outlet to connect the upstream and downstream bed elevations and to facilitate some aquatic passage. Due to the existing site conditions, NCDOT requests a waiver from the Regional Condition 2(b)(e) permit depth specification, for the construction of this project. Temporary cofferdams and bypass pumping will be utilized, as needed, to manage the stream during construction. Upon project completion, the channel disturbed by the temporary cofferdams will be restored to pre-project conditions and the area seeded and stabilized. The total scope of the work will result in 60 feet of permanent impacts to unnamed tributary to Shoal Rock Creek, which is classified as a WS-IV watershed by the Division of Water Quality. The project is not located within '/z mile of any critical watershed area nor is SR 1824 a rural or urban arterial; therefore, hazardous spill basins are not required. Enclosed is the hazardous spill basin checklist. Based upon correspondence with the State Historic Preservation Office (SHPO), dated 2/20/07, the proposed project area has been reviewed and SHPO has determined that no historic properties will be affected (ER Number 07-0064). This office has conducted a GIS and field survey for the project threatened/endangered species. The federally listed species for Cleveland County (USFWS listed dated March 8, 2006) include the dwarf-flowered heartleaf (Hexastylis nan~ora).

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. No heartleaf species were observed and there appears to be limited suitable habitat within the proposed project area. NCDOT is recommending a finding of "no effect" for T&E species. 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: 150455-55120005-120.023066-3855 • TIP #: NA • Project Category: $200.00 Fee If you have any questions or concerns, please feel free to contact me at (704) 480-9044.

Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 8. Pond Creation NO POND IMPACTS If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: Size of watershed draining to pond: Expected pond surface area: VII. 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. The road is being_paved on the existing roadway footprint. The increase in nine leneth is due to the proposed skew to better align the upstream and downstream sections. The existing_pipe is on a ~7.4% gradient and the outlet is perched. The proposed pipe on new alignment will be placed on -~3% gradient. The outlet will still be perched; therefore, a 10-foot rock ladder will be constructed to connect the upstream and downstream elevations and to facilitate some aquatic passage. 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. Page 5 of 8 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 nronosed impact. and fimcti~n and relative vah~e of the imnactPd 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://h?o.enr.state.nc.us/newetlands/strm~~ide.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. MITIGATION NOT ANTICIPATED 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

This program is developed pursuant to the requirements contained in the Rules and Regulations for Erosion and Sedimentation Control which were adopted by the North Carolina Sedimentation Control Commission on April 10, 1974. PROJECT DESCRIPTION SR 1824 (Hatches 3pang~er Rd) from its intersection with SR LOOS to 3R 1809. It will be constructed to the attached typical section. No problem areas are anticipated. The work will be completed during the 07/08 construction season. CONSTRUCTION SEQUENCE 1. Grading to be started by state forces. Install all necessary silt fences, sediment basins, and check dams and begin clearing construction area. 1. Kough grade the construction area anti begin installing any storm drainage and/or cross lines. Install inlet and outlet protection as storm drainage is being installed. 3. As an area is brought to finish grade and the black base is placed for the road, and the shoulder finished, then seed, mulch and tack should be provided for denuded areas. 4. Leave all erosion control devices in place until vegetation has been established sufficiently to w7thstand erosion. DO NOT remove any erosion control devices until directed by the County Engineer. MAINTENANCE PLAN 1. All erosion and sediment control practices will be checked for stability and operation follow7ng every runoff producing rainfall but in no case less than once every week. Any repairs will be made immediately to maintain all practices as designed. 2. Sediment will be removed from behind the sediment fence when it becomes about 0.5 feet deep at the fence. The sediment fence will be repaired as necessary to maintain a barrier. 3. All seeded areas will be fertilized, reseeded as necessary and mulched according to the instruction in the seeded specifications to maintain a vigorous, dense vegetative cover. 4. Outlet protection will be installed when outlets are installed. Filter fabric will be placed under the entire stone section and will be repaired and replaced if damaged during any phase of construction. 5. Sediment will be removed from the basin when it reaches 1.0 foot below the emergency spillway. The filter stone is to be cleaned or replaced when basin no longer drains properly. GROUND COVER FOR SLOPES, FII.LS AND OTHER GRADED AREAS The angles for graded slopes and fills shall be no greater than the angle which can be retained by vegetative cover or other adequate erosion control devices or struchrres. Seeding should be done in accordance with the specifications for that season of the year. Additional erosion control measures may be required depending on the actual field conditions. _ ~ . ~~ i ins I .n. !4P ~ • 1.
