RE: Dixon Avenue Convenience Center Culvert Replacement
313 N. Dixon Avenue
Dear Ms. Higgins:
Enclosed is a completed PCN for a culvert replacement project at our Dixon Drive
Convenience Center. The purpose for the project is to replace an undersized,
collapsed culvert with a new, larger culvert pipe.
This submittal is a Courtesy Copy as the impacts associated with this project are
limited to adding rip -rap to a 10 -foot diameter existing scour hole. The scour hole
already contains rip -rap, gravel, and asphalt chunks. Additional rip -rap will be added
for stability. We estimate adding approximately 1.5 cubic yards of rip -rap within the
footprint of the existing scour hole.
Since no additional impacts to Neuse River riparian buffers are proposed (e.g. no
additional impervious area is being added), written approval for coverage under NC
General Certification 3883 is not required.
Please feel free to contact me at (919) 462 -3931 if you have any questions regarding
this application or project.
Sincerely,
Eric W Kulz

Dear Mr. Shaeffer:
Enclosed is a completed PCN for a culvert replacement project at our Dixon Drive
Convenience Center. The purpose for the project is to replace an undersized,
collapsed culvert with a new, larger culvert pipe. The new pipe is the same length as
the old pipe (260 LF) and will be placed in the same alignment as the existing pipe.
Impacts associated with this project are limited to adding rip -rap to a 10 -foot diameter
existing scour hole. The scour hole already contains rip -rap, gravel, and asphalt
chunks. Additional rip -rap will be added for stability. We estimate adding
approximately 1.5 cubic yards of rip -rap within the footprint of the existing scour hole.
Since no additional impacts to Neuse River riparian buffers are proposed (e.g. no
additional impervious area is being added), written approval for coverage under NC
General Certification 3883 is not required. A Courtesy Copy has been forwarded to
the NC Division of Water Resources.

this application or project.

3e. Describe the overall project in detail, including the type of equipment to be
used: The project will involve replacement of an existing, collapsed culvert with a
new, larger pipe. The existing pipe is a 260 -foot 18" corrugated metal pipe (CMP) which
was installed at an unknown date to convey an intermittent stream beneath the public
works facility. The watershed above the site includes residential properties (townhomes
and single - family lots) and Taylor's Pond. The existing pipe has recently collapsed and
causes water to back up beneath the railroad tracks during heavy rain events.
Currently, the Town has a pump on standby to help prevent flooding of the upstream
residential properties.
The proposed project involves removal of the existing 18" CMP and replacing ,it with a
42" double - walled High Density Polyethylene Pipe (HDPE). The length of the pipe will
not be changed, and the new pipe will be installed in the same location as the existing
pipe. Currently, the pipe discharges to a 10 -foot diameter scour pool, which is lined with
rip -rap, gravel, and asphalt chunks. Additional rip -rap will be added to the scour hole for
stability.
Access will be from the sewer easement above the outfall. Installation of the pipe will
be done with a backhoe. Any areas disturbed during installation will be graded and re-
seeded.

DIXON AVENUE CULVERT REPLACEMENT PCN

5d. What data source did you use to determine whether your site would
impact Endangered Species or Designated Critical Habitat?
The NCNHP database search conducted for the USGS Cary Quadrangle
(www.ncnhp.org /web /nhp /database- search) identified historical occurrences of the
endangered Michaux's sumac (Rhus michauxii). Michaux's sumac is a woody shrub
found in open woods in rocky or sandy soils. Wooded areas on the site are limited to a
narrow riparian buffer along the stream, which forms a closed canopy over the stream.
Soils consist of sandy and silty clays. No specimens of Michaux's Sumac were
observed during a site visit by Eric Kulz on 5/8/15. Based upon this information, the
project is anticipated to have No Effect on this species.
The USFWS Environmental Conservation Online System (ECOS) — Species Accounts
by County
(httD'Hecos.fws.gov /tess public/ countySearch ! specie's ByCountyReport. action ?figs =371
83) was consulted. In addition to Michaux's sumac, three additional species were listed
as having recorded occurrences in Wake County.
The endangered red - cockaded woodpecker (Picoides borealis) has historical
occurrences in southern Wake County. According to the ECOS species profile, this
species inhabits mature pine forests. The site consists of maintained, graveled areas
with a narrow riparian buffer comprised of young and middle -aged hardwoods and
exotic species in the understory and shrub layer. Based upon this information, the
project is anticipated to have No Effect on this species
The endangered dwarf wedgemussel (Alasmidonta heterdon) is found in creeks and
rivers in stable habitat with substrates ranging from mixed sand, pebble, and gravel, to
clay and silty sand. The UT to Crabtree Creek into which the culvert discharges is a
perennial stream with a sand, gravel and cobble substrate. However, this project does
not include any impacts to the receiving stream. Based upon this information, the
project is anticipated to have No Effect on this species
The Northern Long -Eared Bat (Myotis septentrionalis) is proposed as endangered.
According to the USFWS Endangered Species Fact Sheet on the northern long -eared
bat, this species spends winter hibernating in caves and mines, called hibernacula.
They typically use large caves or mines with large passages and entrances; constant
temperatures; and high humidity with no air currents. No caves or mines are located in
the vicinity of the project site.

During the summer northern long -eared bats roost singly or in colonies underneath
bark, in cavities, or in crevices of both live and dead trees. Males and non - reproductive
females may also roost in cooler places, like caves and mines. This bat seems
opportunistic in selecting roosts, using tree species based on suitability to retain bark
or provide cavities or crevices. It has also been found, rarely, roosting in structures like
barns and sheds. Most of the project work will occur in maintained, graveled areas, a
maintained sanitary sewer easement, and the narrow riparian buffer. Trees consist of
small to middle -aged trees. No structures as described above occur within the project
site.
Based upon this information, the project is anticipated to have No Effect on this
species.
