D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The proposed greenway alignment was chosen to avoid the FEMA floodway where possible and minimize stream impacts with the use of
perpendicular stream crossings. Crossing locations were chosen to minimize stream bank modifications. The greenway is sloped to drain stormwater
into stormwater ditches and discharged to the creek. The pipe outlets will be stabilized with rip rap in order to reduce erosion.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Sediment and erosion control measures will be used throughtout the project. Silt fence, in particular, along with stone outlets will be used to prevent
sedimentation from entering the streams. The fencing will also serve to restrict the contractor's construction corridor. For construction of the culvert,
the stream will be diverted away from the construction site by use of an impervious dike and temporary by -pass pump. A temporary stream crossing
will provide access to the site during bridge construction while limiting run -off potentials

RE: Application for Section 404 Nationwide Permit 14 and Section 401 Water
Quality Certification for the Cedar Trail Greenway Connection
Forsyth County, North Carolina. City Project No. 200840 (STIP EB -5523)
Dear Sir or Madam:
The City of Winston -Salem proposes to install a greenway connection from Cedar Trail to
the existing Muddy Creek Greenway. This 3,250 foot trail will be a paved surface 10 feet
wide with grassed shoulders and drainage. An approximately 100 foot pedestrian bridge
will be installed across Muddy Creek as part of the project.
Please find the enclosed copies of the Pre - Construction Notification (PCN) Form, Project
location maps, Permit drawings, and supporting documentation for the above referenced
project.
If you have any questions or need additional information, please call me at 747 -6833.

Dear Mr. Love:
Subject: Muddy Creek Greenway Connections, Winston- Salem, Forsyth County, North Carolina
We have received your emails of May 19, 2015 and May 22, 2015, requesting our comments on the
subject project. The following comments are provided in accordance with the provisions of
section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531- 1543).
We concur with your assessment that with a commitment to winter tree clearing (August 15 to
May 15), the proposed project will not adversely affect the northern long -eared bat and will not
affect any other federally listed endangered or threatened species. Therefore, the requirements
under section 7(c) of the Endangered Species Act are fulfilled. Obligations under section 7 of the
Endangered Species Act must be reconsidered if. (1) new information reveals impacts of this
identified action that may affect listed species or critical habitat in a manner not previously
considered, (2) this action is subsequently modified in a manner that was not considered in this
review, or (3) a new species is listed or critical habitat is determined that may be affected by the
identified action.
Please contact Mr. Allen Ratzlaff of our staff at 828/258 -3939, Ext. 229, if you have any questions
regarding our comments. We have assigned our Log No. 4 -2 -15 -296 to this project; please refer to

PROPOSED PROJECT DESCRIPTION
Flooding Source Proposed,Project Location of Proposed Project
Muddy Creek Tributary to New Bridge The pedestrian bridge crosses,Muddy Creek Tributary to at approximately
150 feet upstream'of its confluence with Muddy Creek Tributary. The
crossing,(Cedar Trail Greenway) will conned the greenway beginning at
Muddy Creek Greenway and ending at the,Cedar Trait Road This
greenway also follow Muddy Creek Tributary on the north side until it
crosses Muddy Creek tributary 1A and ends at Cedar Trail roadway, The
proposed greenway, bridge along Muddy Creek Tiibutary•1A is located
inside the'backwater areas of Muddy Creek Tributary
SUMMARY,OF IMPACTS TO FLOOD HAZARD DATA
Flooding "for the area of Muddy Creek Tributary 1A affected by the proposed project is controlled by backwatereffects from Muddy Creek Tributary, hence there will be no
change'in the flood hazard information (i e , BFES', SFHA (the area subjected to inundation by the base flood), Zone designations).

COMMENT
This document provides the Federal, Emergency Management Agency's (FEMA's) comment regarding a request I& a, CLOMR for the project described above,
This document is not a final determination; it only provides our comment on,the.proposed project in refaton to the flood hazard information shown,on'the effective
National Flood Insurance Program (NFIP) map. We reviewed'the,submitted data and the data used to prepare the effective'flood hazard information for your
community and determined that the proposed project meets the minimum floodplain•management cri'tena of the NFIP, Your community is responsible for
approving all floodplain developmentand for ensuring thatall permits required by Federal or State/Commonwealth law have,been,received.
StatelCommonwealth, county, and community officials, based on their'knovAedge of local conditions and in the interesf of safety, may set higher standards for
construction in the Special Flood Hazard Area (SFHA), the area'subject to inundation by the base flood. 9 the StateJCommonweaith, county, or community has
adopted, more restrictive or comprehensive floodplain^, management criteria, these cntena take, precedence over the minimum NFIP.cnteria

be developed to provide this detail. This'existing conditions model is thcn-conlpared to the cflbctive model and the proposed conditions model to
dillcrentiale the increases or decreases'in flood hazards caused by more detailed modeling from the increases or decreases in flood hazards that will be

when compared with the existing conditions model without considering backwater ellbets from Muddy Creek Tributary. I lowever, since flooding.ror the
