CONTI, JR. ?'ER\' OR SECRETAR) ' March 21, 201 1 Ms. Liz Hair Asheville Regulatory Field Office US Army Corp of Engineers 11 0 2 7 0 151 Patton Avenue Asheville, NC 28801-5006 SUBJECT: Pipe Replacement/Secondary Road Paving on SR 1527 (Meadow Creek Road), Cleveland County. Dear Ms. Hair: The North Carolina Department of Transportation (NCDOT) proposes to replace a pipe in conjunction with a secondary road paving project on SR 1527 (Meadow Creek Road) in Cleveland County. NCDOT requests authorization to replace a 30-foot long, 24' CMP with an 80-foot long, 42" HDPE with ten feet of associated riprap for stricture stabilization. The proposed pipe will be placed upon -4% slope; therefore it is proposed to place the HOPE pipe on existing streambed grade to prevent upstream destabilization. Due to this condition, NCDOT requests a waiver from the Regional Conditions 2(b) (e) permit depth specifications. A temporary cofferdam pumping system will be used to divert the stream around the construction site as needed. All areas affected by temporary cofferdam system will be graded and restored back to pre-project conditions. The scope of the work will permanently impact 50 linear feet of an unnamed tributary to Wards Creek, which is classified as Class C Waters by the Division of Water Quality. No wetland or high quality waters will be impacted by the project. This office has conducted a GIS and field survey for the project f'or historical sites and threatened endangered species. 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. 'fhe State Historic Preservation Office has reviewed the project area and provided a finding of "No Historic Properties Affected" (2/4/08, ER Number 08-0060). The federally listed species for Cleveland County (USFWS list dated 9/22/10) include the dwarf-flowered heartleaf (Hevashlis noniffnrn)Jationaf Heritage Program records document the nearest Dwarf-Flowered heartleaf location approximately 5.4 miles southeast 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. There is little suitable habitat within the proposed project area and no species were observed. NCDOT is recommending a finding of "no effect" for T&E species. Post Office Box 47 Shelby. North Carolina 28151-0047 a a t . N SR 1527, Meadow Creek Road Pa-e 2 March 21, 201 1 The project area is not located within Y mile of any critical watershed area, nor is SR 1527 a rural or urban arterial; therefore, hazardous spill basins are not required. Enclosed is the hazardous spill basin checklist. I have enclosed a pre-construction notification for a NW1414, 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: 150455-55 120005-1 20.023 103-3 126 • TIP#: NA • Project Category: 5240.00 Fee If you have any questions or concerns please feel free to contact me at (704) 480-9044.

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. PROtMCT DESCRIPTION bleadow creek Rd (3R 1527(. The NCDOT will be grading, widening, and paving Meadow creek rd.. No problem areas are anticipated. The work will be completed during the 2010/2011 construction season. `I 1527 ;i l \ ' Qp PROJECrAREA 1524 i 15.27 N 1526 1523 !/VV1716 ® . 24 =SR EEOC RQ 1. IC cleve.don 05202009 09:39:35 AM CONSTRUCTION SEQUENCE I. Grading to be started by state forces. Install all necessary silt fences, sediment basins, and check dams and begin clearing construction area. 2. Rough grade the construction area and begin installing any stone 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 withstand 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 following 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, FILLS 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 structures. 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. 4.2 PIPE/CULVERT INSTALLATION (Taken from BMP Aug.2003, page 26) This section describes the steps to take when an existing pipe or culvert is being constructed or replaced on a jurisdictional stream. 1. Prior to installing Erosion Control, identify permit conditions and impact area limits. Contact the Division Environmental Officer (DEO) for information on permit drawings or jurisdictional areas. Erosion Control 2. Install temporary silt fence or silt ditch to treat runoff from the work area or isolate the work area from the jurisdictional areas, such as wetlands or riparian buffers (See Section 5.1). 3. Install Temporary Rock Silt Check Type "A" or Temporary Sediment Dam Type "B" in ditch lines to contain sediment prior to discharge into the watercourse (See Section 5.1). " Do not install Temporary Rock Silt Check Type "A" or Temporary Sediment Dam Type "B" in stream channel Managing the Water Course 4. On larger streams, flow diversion may be used to isolate the work area using bypass pumping, piped diversion or fabriclined channel (See Section 5.2). On smaller streams, or at low flow conditions, an impervious dike may be used to temporarily dewater the work area within the stream channel (See Section 5.3). " All temporary in-stream structures must be installed with geotextile fabric beneath them, and removed in their entirety immediately upon completion of in-stream work " In CAMA-AECs, the type of flow diversion is identified in the permit 5. Temporary stream crossings may be utilized in order to provide equipment access, if underlain by geotextile fabric, so that the riprap may be entirely removed (See Section 5.5). " Confirm that the temporary stream crossing is shown in the permit drawings as an approved temporary impact " In CAMA-AECs, the type of temporary Managing the Work Area 6. Dewatering devices are typically needed to keep the work area dry (see Section 5.4). The permit conditions and the amount of available space and length of pipe replacement or project limits will determine the type of dewatering device to be used. Every effort should be made to minimize the extent of the area to be dewatered and the length of time the site is dewatered. " In CAMA-AECs, the type of dewatering device is identified in the CAMA permit 7. Install the pipelculvert per the NCDOT standards and specifications, and any specified permit conditions. Note that pipes and culverts shall be buried a minimum depth below the existing streambed, as defined below, in order to allow for aquatic organism passage during low flow conditions. Variance may be obtained by the DEO to allow for deviations in pipe burial depths due to bedrock, steep gradients in the stream channel, existing headcutting, potential for drainage of upstream wetlands, or other concerns. • Foundation material shall be confined to the pipe%ulvert area and shall not be placed in the existing stream channel outside of the permitted Impact area. • Excavation of the stream channel shall not exceed 10 feet on either end of the new pipe or culvert unless the stream is being relocated per Section 4.9, or if indicated in the permit • Within river basins subject to the Riparian Buffer Rules, projects may be exempt if work in the stream channel is limited to a total of 40 feet of additional impact, Including pipe extension. • In CANA AECs (within the twenty coastal counties), all pipes and culverts must be buried one foot below the existing average streambed elevation. • In other parts of the state, pipes?culverts must be buried as follows: o Culverts 48-inches in diameter or greater shall be buried one foot below the streambed elevation. Average streambed elevation shall be measured from multiple measurements taken outside of the area of scour or road crossing disturbance, outside of the ROW limits, if necessary. o Culverts less than 48-inches shall be buried a depth equal to 20'/ of the pipe%ulvert diameter, such as the following examples. The hydraulic conveyance of the culvert however should not be compromised. Examples: • 36"= 7" • 30" = 6" • 24" = 5" • 18"=4" 8. Stream pattern, dimension and profile shall be maintained by pipelculvert installation. • A 4-foot diameter pipe%ulvert installed in a 2-foot wide stream may require baffles in order to maintain aquatic organism passage (AOP) during low flow conditions. • Pipe size should at least match stream width wherever possible, but a 2-foot wide culvert installed in a Moot wide stream may also need baffles to reduce velocities. • Two 48 inch pipes installed in a 10.foot wide stream would require that one pipe be installed at a lower elevation, and In alignment with the low flow stream channel elevation, so that AOP is maintained during low flow conditions. • The low flow pipe should be aligned with the deepest part of the stream channel, so that flow is maintained during low flow conditions. • No "live" or fresh concrete shall come into contact with Jurisdictional waters until the concrete has cured. 9. Install the riprap shoulder slope and outlet protection on upstream and downstream channels where indicated on the permit drawings (See Section 5.6). Do not exceed approved limits in the permit. Contact the DEO if the Permit or permit drawings are not clear. ' ROW shall consist of clean rock or masonry material free of debris or pollutants (such as asphalt). Outlet Protection should be countersunk at least one foot below the average stream bed elevation. • Placement of rfprap within Jurisdictional waters must be the minimum necessary to protect or ensure shoulder slope and streambank stability. 10. Remove temporary now diversion or dewatering devices and accumulated sediment before allowing stream flow to resume through the new pipe or culvert. • The impervious dike shall be completely removed to pre-project conditions. • Care should be taken to not disturb or destabilize the undisturbed streambed during removal of temporary devices. 11. Stream realignment can occur within approved permit impact limits. Minimize sharp or acute angles in stream alignment wherever possible. Stream channel pattern, dimension and profile should be maintained similar to the upstream and downstream stream reach. 12. Bioengineering techniques may be used to stabilize streambanks where feasible. 13. Begin backflll operations. Intermediate erosion and sedimentation control BMPs shall be installed prior to the backfill operation to provide containment between the work area and the watercourse. pipe/culvert 14. if the backf I sho dbe placed to allow larger for the removalpof the enough temporary stream crossing. If no temporary stream crossing is required then enough backfll should be placed to prevent a washout during a minor storm event. Ground Stabilization 15. Upon completion of backfill operations, prepare slopes and other disturbed areas and stabilize (See Section 5.6). 16. Maintain erosion and sedimentation control measures until ground vegetation is well established. Site Cleanup 17. Upon establishment of vegetation, remove remaining erosion and sedimentation control BMPs, stabilize and reestablish remaining disturbed areas to proper grade, such as buffers, wetlands, and water. • Within jurisdictional waters d wetlands all temporarily disturbed areas shall SEd• . . 1630.03 Temporary Silt Ditch ............................ 1630.05 1605.01 1606.01 1622.01 1630.01 Temporary Diversion &Mw ,o Temporary Silt Fence ............................
