RE: Nationwide Permit 14 Application—Dunn Creek Greenway Phase 4
(SAW-2022-00621, NBRRO#22-089)
Town of Wake Forest, Wake County, North Carolina
Dear Ms. Norton and Ms. Cohn:
On behalf of our client, the Town of Wake Forest, Kimley-Horn is submitting the attached application
for authorization under Nationwide Permit (NWP) 14 for the above referenced project in Wake
County. The Town of Wake Forest proposes to construct Phase 4 of the Dunn Creek Greenway, a
0.56-mile extension to the existing multi-use path system as part of the Town of Wake Forest's Open
Space & Greenway Plan. The project would tie into existing greenway segments constructed by
private development and would connect into Del Webb at Traditions, The Orchards at Traditions, and
Flaherty Farms. The project will require two greenway easements, one through Del Webb at
Tradition's common open space and the other at Flaherty Farms. The balance of the project will be
located on property owned by the Town of Wake Forest.
Kimley-Horn staff delineated the project study area in January 2022 and identified two wetlands (W1
and W3) and four streams (Dunn Creek [Hatters Branch], S1, S2, and S3). April R. Norton of the
USACE responded to the Preliminary Jurisdictional Determination request confirming the delineated
stream and wetland boundaries on April 26, 2022 (SAW-2022-00621). Chris Smith of the NCDWR
issued a Buffer Determination Letter for the project on April 20, 2022 (NBRRO #22-089).
Unavoidable permanent impacts to streams, wetlands, and the associated Neuse River Basin Buffer
Zones will result from the proposed greenway alignment. Permanent and permanent no-net loss (P-
NNL) stream impacts at Stream and Wetland Impact Sites 1 as a result of the proposed culvert
extension and associated keyed-in rip rap outlet, and at Stream and Wetland Impact Site 2 as a result
of the proposed culvert installation and associated keyed-in riprap outlet. Temporary impacts to
streams S1 and S2 will result from the construction access necessary to install the proposed culverts
and rip rap. All temporarily impacted streams will be returned to pre-existing conditions upon
completion of construction. Dunn Creek (Hatters Branch) will be crossed with a prefabricated

pedestrian bridge as shown in the attached plan sheets; therefore, no impacts to Dunn Creek are
anticipated. At Stream and Wetland Impact Site 2, permanent wetland impacts resulting from
construction of the greenway project will involve the placement of riprap along the wingwalls and toe
of slope for the new culvert installation, as well as grading and placement of fill material to construct
the greenway. Temporary impacts to wetlands will result from necessary construction access
corridors, and will be returned to preconstruction contours after completion of the project
Additionally, portions of the protected riparian buffers of Dunn Creek and streams S1, S2, and S3 will
be permanently impacted at Buffer impact Sites 1-5 resulting from the construction of the greenway
path and shoulder, as well as for the installation of a prefabricated pedestrian bridge that will be used
to span Dunn Creek.
