SUBJECT Roadway Embankment/Streambank Stabilization on Interstate 40 Westbound, Iredell
County
Dear Mr Wrenn
The North Carolina Department of Transportation proposes to stabilize the Interstate 40 Westbound
roadway embankment around Mile Marker 142 in Iredell County Large rock will be utilized at the base
of the embankment for a distance of 60 feet (< 1 cubic yard/running foot below ordinary high water) and
earth fill will be placed behind the rock to reconstruct the embankment Presently, the adjacent stream
channel is braided at the base of the roadway embankment, therefore, the base rock will be placed in the
south braid of the stream channel and a portion of the instream bar will be excavated to create a single
channel from the north braid Upstream and downstream cross-sections were measured to establish and
"normal" channel width of - 9 feet (see attached cross-sections) Temporary cofferdams and bypass
pumping will be used for stream management during construction Upon project completion, the areas
impacted by the temporary cofferdams will be returned to pre-project conditions and all areas seeded and
stabilized The scope of the work will result in a total of 60 linear feet of permanent impacts to Goble
Creek, which is classified as a WS-IV watershed by the Division of Water Quality
Interstate 40 is a rural and urban arterial, however, the project is not located within '/2 mile of the critical
watershed area, 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 The federally listed species for
Iredell County (USFWS list dated January 31, 2008) include bog turtle (Clemmys muhlenbergii) and the
Dwarf-flowered heartleaf (Hexastylis naniora) Natural Heritage Program records document the nearest
dwarf-flowered heartleaf location approximately 7 0 miles southwest of the proposed project area (in
Catawba county) 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 neai springheads There did not appear to be suitable

habitat witliin the proposed project area and no heartleaf species were observed No impact on this
species is anticipated Natural Heritage Program records document the nearest bog turtle location
approximately 17 0 miles northeast of the proposed project area Bog turtles are typically found in bogs,
marshes, and wet pastures There is no suitable habitat located within the project area T/SA species are
not subject to Section 7 consultation, however, no impact on this species is anticipated The proposed
project will have NO EFFECT on the bog turtle and the dwarf-flowered heartleaf
I have enclosed a pre-construction notification for a WQC 3689 (Bank Stabilization), 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 150461-55120005-12 104911-3108

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 High stream flows appear to be
causinsz erosion of the interstate embankment, which must be stabilized and repaired for the
safety of the traveling public The south braid of the braided stream in the embankment repair
area will be filled to repair the embankment and a portion of the instream bar at this same
location will be excavated to create a single channel at a "normal "channel width Cross-sections
were surveyed upstream and downstream of the site to provide reference stream dimensions
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
Pale 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 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
