`1~` Bridge Number 53 on SR 1799 over North Branch of Hungry River
Henderson Courrty
Action ID Number 200230310
Dear Mr. Baker:
The North Carolina Department of Transportation (NCDOT) is proposing to replace Bridge
Number 53 on SR 1799 over Hungry River (C, Tr) in Henderson County. During recent flood
events, the old structure was washed away. NCDOT proposes to replace this structure at the old
bridge location.
A temporary bridge was constructed by laying beams on the old concrete footers that remained
after the floods. There are two interior footers currently in the water, and the western end bent is
partially in the water. These footers will be removed and a spanning structure will be installed.
Traffic will be detoured by employing a staged construction process allowing traffic on half of the
bridge during construction. The new bridge is designed to minimize impacts by implementing
longer spans and increasing hydraulic capacity. The removal ofthe existing structure shall be
performed by sawing andlor non-shattering methods such that debris will not fall into the water.
All work will be performed in a dry environment. Sandbag cofferdams wdl be used if necessary to
ensure a clean, dry work area, and to minimise impacts to aquatic habitats.
Y am attaching the Categorical Exclusion document and a marked county map. The USGS map
location is in the CE document.

B-4349 on SR 1388 Page 2 July 26, 200'7
The potential impacts to federally endangered and threatened species were investigated and the
results are found in the CE document. The conclusion was there would be "no effect" for the
species listed for Henderson County.
The potential impact to historic properties and archaeological resources was investigated. The
State Historic Preservation Office recommended no archaeological work and determined that
there were no structures over 50 years old, no structures less than 50 years old that met criteria
for consideration and there are no National Register-listed properties.
Impacts to Waters of the United States
Hungry River is shown on the USGS topographic map as a perennial stream. This stream has a
well-defined channel with a substrate of cobble, gravel and sand. The channel lacks vegetation.
The stream has cuff cient flow to support aquatic life, including fish. For these reasons, we
believe this stream is under the jurisdiction of the U. S. Army Corps of Engineers. In order to
construct the project, it will be necessary to impact waters of the United States in the Broad River
Basin. Specifically, NCDOT is requesting to replace Henderson County Bridge No. 53 with a
cored slab structure over Hungry River. Listed below is a summary of the proposed impacts.

Since the existing footers will be removed and new footers constructed away from the water,
there will be no mitigation required for this project. There will. only be temporary impacts of
cofferdams for removal of old in-water structures.

The best management practices will be used to nrinimize and control sedimentation and erosion on
this project. The construction foreman will review all erosion control measures daily to ensure
sedimentation and erasion is being effectively controlled. If the planned devices are not
functioning as intended, they will be immediately replaced with better devices. All commitments
on the Project Green Sheets will be adhered to.

impacts from offsite sedimentation from the project site will be avoided by the implementation
of appropriate BMP's. (See manual and attached Erosion Control Diag am)
VIII. Mitigation
DWQ - Tn 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.
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
httb ~//h2o. enr.state. nc.us/ncwetlands/strmgide. html.
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.

INTRODUCTION : A Categorical Exclusion (CE) for the replacement of Bridge
No. 53 was signed in June 2003 (see Figure 1 for project location). The CE identified
Alternative A, which replaces the bridge on new alignment east (downstream) of the existing
bridge, as the Preferred Alternative. Traffic would be maintained on the existing structure
during construction. Alternative B, which replaces Bridge No. 53 on existing alignment, was
eliminated because it involved a signalized, one-lane on-site detour and was less economical than
Alternative A. Prior to construction of the Preferred Alternative, the original bridge washed out
in June 2006 (see Figure 2). A temporary bridge is currently in use. Replacement of the bridge
therefore became an urgent situation, necessitating the change to a replace in place option
(Alternative B) as the Preferred Alternative. This Addendum describes the new Preferred
Alternative, associated impacts and supporting information.
I. PREFERRED ALTERNATIVE
Alternative B (preferred) replaces Bridge No. 53 on the existing alignment. A proposed
realignment of SR 1799 of approximately five feet will alleviate a sharp curve on the southern
approach and allow stage construction of the new structure (see Figure 3B) and maintenance of
traffic. Traffic will be maintained onsite with the current one-lane temporary structure.
The proposed replacement structure consists of a 110-foot bridge with a clear roadway width of
approximately 27 feet. The proposed bridge will consist of two ten-foot travel lanes and an
approximately 3.5-foot shoulder on each side (see Figure 3A).
The proposed approach roadway will consist of two ten-foot travel lanes and two-foot
shoulders. The south approach is approximately 172 feet long and the north approach is
approximately 225 feet long. The proposed grade will be approximately the same as the original
roadway. The proposed design speed is 15 mph.
11. ESTIMATED COSTS
The estimated costs of replacing Bridge No. 53, based on current prices, are shown in Table 1.
The estimated cost of the project as shown in the Draft 2007-2013 (STIP) is $751,000, including
$151,000 prior years cost and $650,000 for construction.

ill. SUMMARY OF ANTICIPATED IMPACTS
This section provides a summary of anticipated impacts for the Preferred Alternative. Detailed
descriptions of the existing conditions and field survey methods are included in the June 2003
Categorical Exclusion.
A field survey was conducted on December 18, 2006. The area surveyed included an area
bounded by the cut and fill slopes and stormwater devices, as depicted on final design plans.
This area is referred to as the construction footprint. Because the bridge replacement will be at
the existing location, the construction footprint is primarily within the existing disturbed
roadway corridor. The proposed realignment of SR 1799 will result in an impact to a small area
of thick immature trees that was previously an "old field" vegetative community.
A. TERRESTRIAL VEGETATIVE COMMUNITIES
Table 2 lists the anticipated impacts to terrestrial vegetative communities. The impacts axe less
than those shown in the CE for two reasons:
• The 2006 survey area was based on final design plans.
• The alternative in the CE included a temporary detour that is no longer necessary.

Vegetative Communities
Acidic Cove Forest 0.04
Montane Alluvial Forest 0
Urban/Disturbed Land 0.33

,+
B. WETLAND COMMUNITIE5
No jurisdictional wetlands were found within the project area.
C. WATER RE50URCE5
Temporary construction impacts due to erosion and sedimentation will be minimised through
implementation of a stringent erosion control schedule and the use of best management
practices. Long-term construction impacts are expected to be negligible. In order to minimise
impacts to water resources, "Guidelines for Construction of Highway Improvements Adjacent
to or Crossing Trout Waters in North Carolina" (October 27, 1992) in addition to NCDOT Best
Management Practices (BMPs) for the Protection of Surface Waters will be strictly enforced
during the entire life of the project. There will be an in-water work moratorium from
November 1 to April 15 to minimise impacts to trout spawning.
D. FEDERALLY PROTECTED SPECIES
US Fish and Wildlife (USFWS) records (April 27, 2006) were reviewed in November 2006 fox
federally protected species occurring in Henderson County. There have been no changes to the
list since the June 2003 document. A review of North Carolina Natural Heritage Program maps
indicates that there are no federally protected species within one mile of the project area. Table
3 lists the federally Threatened and Endangered species known to occur in Henderson County.

The biological conclusions for the four plant species listed were reassessed. Results are
presented in the following paragraphs.
Small-whorled pogonia (Isotria medeoloides)
Federal Status: Threatened
State Status: Endangered
Biological Conclusion: No Effect
The original area surveyed included a substantial amount of land not included in the final bridge
design. A survey was conducted on December 18, 2006 to determine if suitable habitat is
B-3666 Categorical Exclusion Addendum

present within the construction footprint for the small-whorled pogonia. No suitable habitat
was observed within this area. A small amount of wooded areas will be affected but these areas
are outside of the stream floodplain and are thick with young hardwoods, hemlocks, and cedar.
Therefore, suitable habitat is not present for the small- whorled pogonia and the project is
expected to have NO EFFECT on the small-whorled pogonia. The original survey for the
small-whorled pogonia was conducted in July 2001, and no individuals were observed. NCNHP
has no records of small whorled pogonia individuals within aone-mile radius of the project site.
Swamp pink (Helonras bullata)
Federal Status: Threatened
State Status: Threatened -Special Concern
Biological Conclusion: No Effect
Suitable habitat for swamp pink consisting of mountain swamps and bogs is not present within
the construction footprint. NCNHP has no records of swamp pink individuals within aone-
mile radius of the project site. Therefore, the proposed project will have NO EFFECT on this
species.
Mountain Sweet Pitcher Plant (Sarracenia rubra ssp. jonesil}
Federal Status: Endangered
State Status: Endangered -Special Concern
Biological Conclusion: No Effect
Suitable habitat for the mountain sweet pitcher plant consisting of mountain bogs and along
streams on granite rock faces is not present within the construction footprint. The original
survey found suitable habitat for the mountain sweet pitcher plant; however, a plant survey
conducted in June 2001 found no individuals within the study area. NCNHP has no records of
mountain sweet pitcher plant individuals within aone-mile radius of the project site. Therefore,
the proposed project will have NO EFFECT on this species.
White irisette (Sisyrir~chrum drehotomum)
Federal Status: Endangered
State Status: Endangered
Biological Conclusion: No Effect
Suitable habitat for the white irisette consisting of shallow, circumneutral soils is not present
within the construction footprint. The soils within the construction footprint have been
determined to be too acidic in nature to sustain the white irisette. NCNHP has no records of
white irisette individuals within aone-mile radius of the project site. Therefore, the proposed
project will have NO EFFECT on this species.
