SUBJECT: Pipe Replacement on SR 1833 (W. ChesTnut St. Ext. ), Gaston County
Dear Mr. Kichefski:
The North Carolina Department of Transportation requests authorization to replace a
deteriorating pipe on SR 1833 (W. Chestnut St. Ext.) in Gaston County. NCDOT proposes to
replace the existing 60", 45-foot CMP with a 72", 70-foot CMP. The new pipe inlet will be
shifted approximately 8 feet to better align with the upstream cbannel; therefore, approximately 8
feet of stream channel will be lost. The exlsting pipe is perched and on a 2.6% slope, the new
pipe will be installed at a�4.0% slope. Due to the increase in the pipe slope, an existing shallow
scourhole will be armored (7 feeY) for energy dissipation. The invert elevation of the proposed
pipe outlet (86.7) is approximaTely at Ybe same elevation as the streambed immediately
downstream of the existing scourhole (86.4) and is below the current water surface elevation
(86.9). The inlet invert will be buried based upon the exisfing streambed elevation immediately
upsYream of the new pipe. It is anticipated that the bedrock observed in the streambed �upstream
of the new pipe will provide grade control should upstream headcutting be initiated due to the
slope of the proposed pipe (4%) and the upstream bed slope (�3.5%). Due to the exis6ng site
conditions, NCDOT requeste a waiver from the Regional Condirion 2(b)(e) permit depth
specification, for the construction of this project Five feet of riprap will be used at the pipe
inlet. A temporary cofferdasn pumping system will be used to divert the stream around the
construction site, as needed. Any areas affected by temporary cofferdam system will be restored
to pre-project conditions.
The scope of the wark involves 28 feet of permanent impacts (8 foot of stream length lost at inlet
and 8 ft increase in pipe length at outlet + 12 feet riprap impacts (for streambed armoring and
structure stabilization) to an unnamed tributary to Mauney Creek, which is classified as a Class
WS-IV Watershed by the NC Division of Water Resources. The stream is also on the 303d list as
impaired for Benthos.
The project is not located within 'h mile of any critical watershed area nor is SR 1833 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.

July 25, 2014
This office has conducted a GIS and field survey for the project threatened/endangered species.
The federally listed species for Gaston County (USFWS listed date September 22, 2010) include
Schweinitz's sunflower (Helianthus schweinitzil) and the bog turtle (Glyptemys muhlenbergii)-
(T/SA- Threatened due to similarity of appearance). National Heritage Program records document
The nearest sunflower location 8A miles southeast of the proposed project area. The sunflower
is usually found in upland open azeas protected from shade or excessive competition.
There is little habitat located in the urban, residential neighborhood. Natural Heritage
Program records document the nearest bog turtle location approximately 3.5 miles southwesi of
the proposed project area. Bog turtles are typically found in bogs, marshes, and wet pastures.
There is no suiTable habitaY located within the project footprint T/SA species are not subject to
Section 7 consultation; however, no impact on tt�is species is anticipated.
[ have enclosed a pre-construction notificarion for a NW#3, 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: 150464-55120005-12B.203611-3300
• TIP#: NA
• Project Category: $240.00 Fee

3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Existing 47-foot long, 60" CMP; landuse is mostlywooded/residential land. Culvert is on paved secondary road.
3b. List the total estimated acreage of all existing wetlands on the property:
0
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
100 feet
3d. Explain the purpose of the proposed project:
The purpose of the proposed work is to replace the deteriorating culvert for the safety of the travelling public.
3e. Describe the overall project in detail, including the type of equipment to be used:
The North Carolina Department of Transportation requests authorization to replace a deteriorating pipe on SR 1833 (W.
Chestnut Street Ext.) in Gaston County. NCDOT proposes to replace the existing 45-ft, 60" CMP with a 70-foot , 72"
CMP. The new pipe inlet will be shifted approximately 8 feet to better align with the upstream channel; therefore,
approximately 8 feet of stream channel will be filled. The new pipe extends 8 feet longer on the downstream end.
Therefore, the total length of fill impacts (increase in pipe length and stream channel lost) is 16 feet. The existing pipe is
perched and on a 2.6% slope, the new pipe will be installed at a-4.0% slope. Due to the increase in the pipe slope, an
existing shallow scourhole will be armored for approximately 7 feet for for energy dissipation. The invert elevation of the
proposed pipe outlet (86.7) is approximately at the same elevation as the streambed immediately downstream of the
existing scourhole. ((86.4) and is below the current water surface elevation (86.9). The inlet invert will be buried based
upon the existing streambed elevation immediately upstream of the new pipe. It is anticipated that the bedrock observed
in the streambed -upstream of the new pipe will provide grade control should upstream headcutting be initiated due to
the slope of the proposed pipe (4%) and the upstream bed slope (-3.5%). Riprap will be utilized on the banks around
the pipe for structure stablization. A temporary cofferdam pumping system will be used to divert the stream around the
construction site as needed. Area affected by temporary cofferdam system will be restored to pre-project conditions. All
Best Management Practices will be utilized during the course of the project. The Project will be constructed using typical
heavy equipment (trackhoe, backhoe, etc.)

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
To bury the new pipe per regulation would result in approximately a 6% pipe slope. An shallow scourhole is located at the
existing pipe outlet. It is proposed that the new pipe invert at the outlet be placed at the elevation of the streambed
immediately downstream of the scourhole. Additionally,the new pipe will be placed at a steeper slope than the existing pipe,
therefore, the existing shallow scourhole will be armored, so as to prevent stream destabilization.
