HUNT JR. GOVERNOR Haywood County SR 1301, Revised Mr. Bob Johnson 215 Army Corps of Engineer Reg. Field Office Room 75, Grove Park Ave. Asheville, NC 28801-2714 Dear Mr. Johnson, GARLAND B. GARRETT JR. SECRETARY `L ,f "X 6 The North Carolina Department of Transportation is proposing to grade, drain, base, and pave primary along the existing roadway of SR 1301, Indian Creek Road, in Haywood County. In order to construct this project in accordance with our current secondary road standards, and due to the *bank stabilization of Indian Creek (DEM Class WS III TR) and the replacement of three (3) pipe culverts, we are requesting authorization under Section 404 of the Clean Water Act. I am sending a straight line diagram with our proposed erosion control construction limits at various sites along the project. In addition, a typical section of the road; cross sections; drawings for the pipe replacements, and the *bank stabilization of Indian Creek; general notes and standards on erosion control measures; and a marked county map are enclosed. We propose to install the new culvert slightly below the existing streambed elevation where bedrock is not encountered to minimize impact to wildlife habitat and allow the existing gradients to remain as unchanged as physically possible. The Banks being stabilized will be sprigged with Hazel or Tag Alders to deter any erosion problems. Additionally, the channel will not be constricted due to the bank stabilization. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion are being effectively controlled. If the planned devices are not functioning as intended, they will immediately be replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe construction and will remain in place until the project is stabilized. Bryson City, NC 28713 July 19, 1996 DIVISION OF HIGHWAYS (9 Mr. Bob Johnson Page 2 July 19, 1996 By copy of this letter I am asking Mr. David Yow, North Carolina Resources Commission, District Fisheries Biologist to comment directly to you concerning the 404 Nationwide permit request.

It is made of permeable filter fabric buried at the bottom, stretched and supported by steel posts. The silt fence reduces the water flow while retaining the sediment. They may also be used to divert water flow to protected outlets. Silt fences need to be checked aftez each significant rainfall to ensure there effectiveness. They must be maintained on a regular basis. Silt fences shall no be installed across streams, ditches, or waterways. AREAS of UsE: • At toe of fill sections where sediment runoff can be stored and contained inside the project limits.

Field Office Room 75, Grove Park Ave. Asheville, NC 28801-2714 Dear Mr. Johnson, DIVISION OF HIGHWAYS Bryson City, NC 28713 June 24, 1996 GARLAND B. GARRETT JR. SECRETARY The North Carolina Department of Transportation is proposing to grade, drain, base, and pave primary along the existing roadway of SR 1301, Indian Creek Road, in Haywood County. In order to construct this project in accordance with our current secondary road standards, and due to rechannelization of Indian Creek (DEM Class WS III TR) and replacement of three (3) pipe culverts, we are requesting authorization under Section 404 of the Clean Water Act. I am sending a straight line diagram with our proposed erosion control construction limits at various sites along the project. In addition, a typical section of the road, cross sections, drawings for the pipe replacements and the channel change of Indian Creek, general notes and standards on erosion control measures, and a marked county map are enclosed. We propose to install the new culverts slightly below the existing streambed elevation where bedrock is not encountered to minimize impact to wildlife habitat and allow the existing gradients to remain as unchanged as physically possible. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion are being effectively controlled. If the planned devices are not functioning as intended, they will immediately be replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe construction and will remain in place until the project is stabilized. By copy of this letter I am asking Mr. David Yow, North Carolina Resources Commission, District Fisheries Biologist to comment directly to you concerning the 404 Nationwide permit request. 9 Mr. Bob Johnson Page 2 June 24, 1996 Also by copy of this letter, I am requesting authorization to proceed under Section 401 of the Clean Water Act from Division of Environmental Management. In addition, I am asking Mr. Yow and Mr. Ed Ingle, Area Roadside Environmental Engineer (NC DOT)and Mr. Richard Phillips (DEHNR), to comment directly to me concerning this permit request. We would like to begin construction as soon as possible. If further information is required, please advise. Your early review and consideration will be appreciated. Yours truly, C, z C. R. Styl s, P.

It is made of permeable filter fabric buried at the bottom, stretched and supported by steel posts. The silt fence reduces the water flow while retaining the sediment. They may also be used to divert water flow to protected outlets. Silt fences need to be checked after each significant rainfall to ensure there effectiveness. They must be maintained on a regular basis. Silt fences shall no be installed across streams, ditches, or waterways. AREAS OF USE: • At toe of fill sections where sediment runoff can be stored and contained inside the project limits.

These type-B rock silt checks help reduce the flow velocity and are generally made of class-B stone. They are used in ditches during construction where the grade meets and/or exceeds 3%. AREAS OF USE: • In channels, roadside ditch outlets, temporary silt ditches, and temporary diversions. • In conjunction with type-B silt basins. DESIGN CRITERIA: • Center of rock silt check shall be at least 1 foot lower than the outer edges (top of channel sides) • The spacing (ft.) = (3 / % of ditch grade) X 100 ft. 27 March, 1992 mU Z Jcc O JQz U)O=OZz OcAU00 .» ~ OnZOw !)

The type-B rock pipe inlet protection -shall be used at pipe inlets which are 24 inches and less in diameter where there is insufficient space for a type-A rock pipe inlet . protection with storage area. The type-B Fock pipe inlet protection utilizes class A stone lined with 4#5 or #57 stone to protect drainage pipe structures by impounding the sediment laden water before it enters the pipe to trap sediment. This device can also be used around the inlet of temporary slope drains where space is limited at the outlet end of slope drain such that a basin or other device can not be used. AREAS OF USE: • At inlets to pipes no larger than 24 inches in diameter where it receives flow from several directions. • In low flow areas where right of way is limited DESIGN • Structural stone - class A • Erosion control stone - # 5 or # 57 stone. • Dam height - 1.5 ft. minimum. 35 March, 1992' -1 f.. ?•;•? ?•4?•i•i•:1.? ?

E F51 36 March.1992 ROCK SII.T SCREEN: t 3 A rock silt screen is a low-level dam structure to be used in streams below culvert sites. Rock silt screens shall be used to trap sediment transported by running water and shall be placed in the stream below the construction site within the right-of- way or easement boundary. The rock silt screen utilizes class B stone lined with #5 or #57 stone to produce a ripple-effect in the stream to settle the larger sediment particles transported in the stream from the construction site. The trapped sediment shall be cleaned out before the device is removed from the stream. AREAS OF USE: • In live streams below construction sites where construction occurs in or adjacent to the stream. • In live streams below a culvert construction site. • Where it can be cleaned before it is removed from stream. DESIGN CRITERIA: • Structural stone - class B stone • Sediment control stone # 5 or # 57 stone • Dam height - 1.5 ft. minimum and 3 ft. maximum (shall not be higher than 1 ft. above normal flow of stream) r March, 1992 h > tj CL O ?
