4h. Explain the purpose of the proposed project:*
The purpose of the proposed project is to replace two existing, failing culverts carrying Dunn Creek north to south, perpendicular to East Juniper Ave in Wake Forest, Wake County, NC.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The project proposes to replace and extend the two failing, corrugated metal pipe (CMP) culverts that currently exists under East Juniper Avenue with two 8' wide by 6' tall reinforced
concrete box culverts, embedded one foot into the channel of Dunn Creek (Hatters Branch). The proposed project is necessary to relieve the failing infrastructure of the two existing
culverts and to limit the number of overtopping events ultimately to prevent future erosion and improve safety of the roadway crossing.
Additionally, the Town is proposing roadway improvements including the addition of curb and gutter, as well as a 5' grass strip and 10' wide multi -use path (MUP) to improve pedestrian
safety along the northern and southern sides of East Juniper Avenue. The proposed Multi -Use Path (MUP) will be connected to the existing Dunn Creek Greenway intersecting the project
corridor. Construction equipment typical of infrastructure projects will be utilized including bulldozers, excavators, graders, dump trucks, concrete trucks, and pavers.

Impacts to streams and protected riparian buffers have been avoided and minimized to the extent practicable. At Impact Site 1, a total of 36 LF (0.01
acre) of permanent stream impacts and 46 LF (0.008 acre) of permanent -no net loss (P-NNL) stream impacts to Dunn Creek (Hatters Branch) within the
project corridor as a result of the replacement and extension of the existing, failing culverts and associated keyed -in rip rap inlet and outlet to the channel
and banks. The associated riprap will provide bank stabilization and help prevent future erosion. The new culverts will be buried a minimum of 1 foot and
will allow for natural flow and movement of aquatic species. Additionally, a total of 16 LF (0.003 acre) of temporary stream impacts would result from the
proposed project to facilitate the construction access necessary to install the proposed culverts and rip rap and for temporary dewatering to allow for
work in the dry.

At Impact Site 1, a total of 6,381 square feet of unavoidable permanent impacts to buffer zone 1 and 2,630 square feet of permanent impacts to buffer
zone 2 of Dunn Creek (Hatters Branch) will result from the proposed project as a result of the culvert replacement and extension, and permanent
drainage easement, as well as the perpendicular construction of the proposed MUPs along the northern and southern side of East Juniper Avenue.
Additionally, a total of 411 square feet of temporary impacts to buffer zone 1 and 200 square feet of temporary impacts to buffer zone 2 of Dunn Creek
(Hatters Branch) will result from the construction access necessary to install the proposed culverts and riprap, and to construct the proposed Iv1UPs.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
The proposed project has been designed to minimize impacts to jurisdictional features to the extent practicable. Dunn Creek (Hatters Branch) will be
diverted using a 15 foot temporary drainage pipe outlet into a diversion channel with the aid of impervious dikes to allow for work in the dry. The projects
culvert replacement is necessary in order to limit overtopping events due to the failing drainage infrastructure and to spatially accommodate the
headwalls and wing walls being installed to enhance slope and channel stability around the culvert outlet and inlets, as well as reduce stream and
riparian buffer impacts. Additionally, rip rap stabilization at the proposed culvert inlet and outlet have been sized to avoid erosive flow through the pipe
and channelization of the stream. The new culverts would allow full conveyance of the 25-year event without roadway overtopping.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Impacts to streams and riparian buffers within the project corridor will be minimized throughout the construction process by avoiding these features with
equipment, materials, and access corridors where practicable. Where feasible, staging and construction access routes will be located in upland areas
throughout the project corridor. Silt fencing will be installed as part of the standard BMP and in accordance with the erosion control plan sheets.
Temporary sediment control measures will be used to reduce stormwater impacts to receiving waters and minimize runoff from the construction sites.
During the construction process, a stream diversion operation sized by ordinary daily flow will be used to allow for in -stream and channel repair work in
the dry.

2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
Yes No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Compensatory mitigation is not proposed for streams as part of this permit application due to minimal permanent impacts to streams (<0.02 acre; <300 LF) resulting from the proposed
project.
Compensatory mitigation is not proposed for streams as part of this permit application due to minimal permanent impacts to streams (<0.02 acre; <300 LF) resulting from the proposed
project. Compensatory mitigation is also not proposed for impacts to the Neuse River Basin riparian buffers as a result of this project. According to NCDWR's Neuse River Basin Buffer
Table of Uses, the buffer impacts associated with the construction of greenways, trails, sidewalks, and/or linear bike/pedestrian transportation systems where built upon area is added to
the riparian buffer, equal to or less than 10 feet wide with two foot wide shoulders are "Allowable Upon Authorization". Additionally, buffer impacts associated with the construction of
perpendicular roadway crossings impacting greater than one -tenth of an acre but equal to or less than one-third of an acre of riparian buffer are considered "Allowable Upon Authorization".
Compensatory mitigation is also not proposed for impacts to the Neuse River Basin riparian buffers as a result of this project. According to NCDWR's Neuse River Basin Buffer Table of
Uses, the buffer impacts associated with the construction of greenways, trails, sidewalks, and/or linear bike/pedestrian transportation systems where built upon area is added to the
riparian buffer, equal to or less than 10 feet wide with two foot wide shoulders are "Allowable Upon Authorization". Additionally, buffer impacts associated with the construction of a
perpendicular roadway crossings impacting greater than one-third acre of riparian buffer are considered "Allowable Upon Authorization". As such, no mitigation is required for the proposed
riparian buffer impacts.

5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat?
As of April 1, 2024, the US Fish and Wildlife Service (USFWS) Information for Planning and Consulting (IPaC) tool lists the red -cockaded woodpecker,
Neuse River waterdog, Carolina madtom, Atlantic pigtoe, dwarf wedgemussel, and Michaux's sumac, with potential to occur within the project vicinity.
IPaC also lists the tricolored bat (Perimyotis subfiavus), a proposed endangered species, and the bald eagle (Haliaeetus leucocephalus), which is
protected under the Bald and Golden Eagle Protection Act, with potential to occur within the project vicinity. A review of the NC Natural Heritage
Program (NCNHP) element occurrence database (updated January 2024) identified no known occurrences of any federally listed species in or within 1.0
mile of the project corridor.
Red -cockaded Woodpecker (RCW)
Suitable habitat for the red -cockaded woodpecker is not present within the project corridor. Forested areas within the study area are mostly composed of
hardwoods and immature pines that are dense, overgrown with invasives, and fragmented. In addition, a review of the NCNHP database records
(updated January 2024) indicates there are no known occurrences of RCW in or within 1.0 mile of the project corridor. Due to lack of suitable habitat and
the lack of known occurrences, it has been determined that the proposed project would have "No Effect" on RCW.
Aquatic Species
Suitable habitat for the Neuse River waterdog, Carolina madtom, Atlantic pigtoe, and dwarf wedgemussel, is present within Dunn Creek (Hatters Branch)
in the project corridor. A review of the NCNHP database records (updated January 2024) indicates there are no known occurrences of any of the
federally listed aquatic species listed above in or within 1.0 mile of the project corridor. According to the NCNHP records, the nearest known population
of Neuse River waterdog is located approximately 6 river miles downstream from the project corridor in the Neuse River. The nearest known population
of Carolina madtom is located approximately 12 river miles downstream from the project corridor in the Neuse River. The nearest known population of
Atlantic pigtoe is located approximately 20 river miles downstream from the project corridor in Walnut Creek. The nearest known population of dwarf
wedgemussel is located approximately 17 river miles downstream from the project corridor in the Neuse River. Due to the lack of known occurrences
and the distance from the project corridor to the nearest known population, no direct impacts to the aquatic species listed above are anticipated.
However, due to the presence of suitable habitat in the project corridor, the biological conclusion for Neuse River waterdog, Carolina madtom, Atlantic
pigtoe, and dwarf wedgemussel for the proposed project is "May Affect, Not Likely to Adversely Affect".
Michaux's Sumac
Suitable habitat for Michaux's sumac is present within the project corridor along the roadside corridors within the project corridor. Although potentially
suitable habitat is present, the regular mowing maintenance schedule and herbicide application observed within these areas would likely inhibit the
plant's success. Kimley-Horn biologists conducted pedestrian surveys for Michaux's sumac within areas of suitable habitat on August 9, 2023, and no
individuals were observed. In addition, a review of the NCNHP database records (updated January 2024) indicates there are no known occurrences of
Michaux's sumac in or within 1.0 mile of the project corridor. Due to the lack of known occurrences and the lack of observed individuals, it has been
determined that the proposed project will have "No Effect" on Michaux's sumac.
Tricolored Bat
The tricolored bat is currently proposed for listing and is not currently protected under the Endangered Species Act (ESA). A review of the NCNHP
database records (updated January 2024) indicates that there are no known occurrences of the tricolored bat in or within 1.0 mile of the project study
area. If listed prior to construction of the project, the Town of Wake Forest will coordinate with the USFWS as appropriate to resolve Section 7 for the
tricolored bat.
Bald Eagle
Habitat for the bald eagle primarily consists of mature forest in proximity to large bodies of open water for foraging. Large dominant trees are utilized for
nesting sites, typically within 1.0 mile of open water. A desktop-GIS assessment of the project study area, as well as the area within a 1.13-mile radius
(1.0 mile plus 660 feet) of the project limits, was performed in January 2024 using 2021 color aerials. Multiple water bodies large enough or sufficiently
open to be considered potential feeding sources were identified. Kimley-Horn biologists conducted pedestrian surveys for the bald eagle within the
project study area and within the 1.13-mile radius on January 24, 2024, and no individuals were observed. Additionally, a review of the NCNHP database
records (updated January 2024) indicates there are no known occurrences of the bald eagle within 1.0 mile of the project corridor. Due to the lack of
habitat and the lack of known occurrences, it has been determined that this project will not affect the bald eagle.
6. Essential Fish Habitat (Corps Requirement)

6a. Will this project occur in or near an area designated as an Essential Fish Habitat? *
Yes No
6b. What data sources did you use to determine whether your site would impact an Essential Fish Habitat?
The NOAA Essential Fish Habitat Mapper was reviewed on April 1, 2024. No essential fish habitat was found within the project corridor or within the
project vicinity
7. Historic or Prehistoric Cultural Resources (Corps Requirement)
7a. Will this project occur in or near an area that the state, federal or tribal governments have designated as having historic or cultural preservation status?
Yes No
7b. What data sources did you use to determine whether your site would impact historic or archeological resources? *
Kimley-Horn conducted a desktop-GIS assessment of the project corridor on April 1, 2024, using the North Carolina State Historic Preservation Office
(NCSHPO) HPOWEB GIS Service database. This assessment was undertaken in order to identify any known National Register (NR), National Register
Study List (SL), and Determined to be Eligible (DOE) for listing properties or historic districts in or within 1.0 mile of the project corridor.
No known historic or cultural resources were identified within the project corridor. However, seven historical and cultural resources were identified within
1.0 mile of the project corridor:
Royall Cotton Mill Commissary (NR) - located approximately 0.81 mile northwest of the project corridor
W.E.B. DuBois School (NR) - located approximately 0.65 mile northwest of the project corridor
Glen Royall Mill Village Historic District (NRHD) - located approximately 0.89 mile northwest of the project corridor
Dr. Calvin Jones House (NR) - located approximately 0.96 mile west of the project corridor
Raleigh & Gaston Rail Corridor (DOE) - located approximately 0.72 mile northwest of the project corridor
Olive Branch Baptist Church (SL) - located approximately 0.84 mile west of the project corridor
Wake Forest Historic District (NR) - located approximately 0.92 mile northwest of the project corridor
73 other historical and cultural resources currently listed as "Blockface", "Survey Only", "Surveyed Only, Gone", and "Surveyed Area", were identified
within 1.0 mile of the project corridor. Due to the listing status, these resources do not currently receive protection under the National Historic
Preservation Act. If the listing status changes to NR, SL, or DOE prior to construction, the potential for impacts to these resources may need to be re-
evaluated; however, due to the distance from the project corridor and the existing uses within the vicinity of the project corridor, it is assumed that the
proposed project will have no effect on these 'Survey Only' resources.
Due to the lack of known historic and cultural resources within the project corridor and the distance from any known historic and cultural resources, as
indicated by the NCSHPO HPOWEB GIS Database (accessed April 2024), it is anticipated that the proposed project will not have a direct impact on any
known NR, SL, or DOE resources.
8. Flood Zone Designation (Corps Requirement)
8a. Will this project occur in a FEMA-designated 100-year floodplain? *
Yes No
8b. If yes, explain how project meets FEMA requirements:
Kimley-Horn has completed a HEC-RAS analysis to evaluate the impacts of the proposed culverts under East Juniper Avenue. The FEMA preliminary
model and peak flow discharges for Dunn Creek (Hatters Branch) were used as the base model for this analysis. It was determined that the proposed
project would not result in any increase water surface elevations during the base flood event. If this cannot be achieved, the appropriate FEMA
certifications will be applied for prior to construction.
8c. What source(s) did you use to make the floodplain determination? *
The FEMA Digital Flood Insurance Map (DFIRM) Panel 3720185100L (effective 07/19/2022) indicate the project corridor is within a special flood hazard
area (Regulatory Floodway Zone AE).
