4a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the
time of this application: *
The project site for this permit application encompasses approximately 38.44 acres and is located southeast
of the intersection of the Clifford Road and New Bethel Church Road in Garner, North Carolina within Wake
County. The project site consists of Phase 2 and 4 of a larger approximately 97.91-acre development area
(phases 1 and 3 have no impacts to Waters of the U.S. or associated buffers). Phases 2 and 4, the project
site, are located entirely within a Wake County parcel identified as 1629024188 which is 47.63-acres. For the
purposes of this review however, the project site is referred to as the aforementioned 38.44-acre area
comprising Phases 2 and 4. The project site is currently occupied by mixed hardwood -pine forest. The project
area is bounded to the north and east by forested and residential land, to the south by forested land, and to
the west by low density residential land associated with Phases 1 and 3. Land use within the vicinity of the
project site consists of low density residential, institutional, and undeveloped areas.
Three unnamed tributaries to Swift Creek are located within the western, northeastern, and southern portions
of the project site. The project site is located within the Neuse River Basin (HUC 030202011004) and within
the Mahlers Creek — Swift Creek sub -watershed. The project site drains to Swift Creek, which has a DWR
Stream Classification of Class C and NSW. According to FEMA Flood Insurance Rate Maps 3720162900J
and 3720161900J (issued May 2, 2006), the site is located within Zone X, areas located outside of the 100-
year floodplain.
A wetland delineation was conducted by Angler Environmental in 2015 and an on -site jurisdictional
determination was conducted by David Schaeffer — USACE representative on December 29, 2015 (USACE
Action Id: SAW-2015-02534). A Neuse River Buffer Determination was issued on February 2, 2016 by DWR
(NBRRO# 15-516).

4h. Explain the purpose of the proposed project:*
The purpose of the proposed project is to construct an affordable and family friendly residential subdivision
with community cohesion and the necessary amenities within the southern section of the Town of Garner,
designed to provide housing to the southeastern section of Wake County, North Carolina.
4i. Describe the overall project in detail, including indirect impacts and the type of equipment to be used: *
The proposed project (38.44-acres) is part of a larger development (97.91-acres) consisting of single family
lots and amenities in addition to roadway and utility improvements. Three (3) road crossings (Crossings 1, 2,
and 3) and 2 (2) utility crossings (Buffer Impact Adjacent to Crossing 3 and Open Cut Water Main Impact)
associated with the residential development are required in order to connect Phases 2 and 4 to the remaining
portions of the development. The attached Impact Maps include the specific details of proposed construction,
impact areas, and includes tables summarizing disturbance amounts.
Installation of Reinforced Concrete Pipes (RCPs) at the three road crossings will be countersunk underneath
the road to maintain the hydrologic connection between the up -gradient and down -gradient portion of the
streams. The Road Crossing Impact "Crossing 1" will have dual 72-inch RCP culverts, and the culvert outfalls
are designed with an energy dissipater pad constructed of class 2 riprap. Both Road Crossing Impact
"Crossing 2" and "Crossing 3" are designed with an energy dissipater pad constructed of Class 1 riprap, and
will utilize a 54-inch RCP culvert and a 48-inch RCP culvert, respectively.
The Utility Crossing Impact adjacent to "Crossing 3" will involve clearing for directional boring within portions
of buffer Zone 2. No impacts will occur within the associated stream or buffer Zone 1 as the utility line will be
bored beneath these areas, avoiding any aboveground disturbance.
The second Utility Crossing Impact identified as "Open Cut Water Main" will involve clearing and temporary
ground disturbance within portions of Zone 1, Zone 2, and a perennial stream for the installation of a water
main associated with the project (10-ft wide easement). Directional boring within this location is not feasible
due to the steep slopes which would make access and use of the necessary equipment impractical and
unsafe.
The proposed pipe orientations are as close to the existing stream alignment as possible with the least
amount of environmental impacts. Due to how the existing stream alignment meanders, realigning the
culverts in a way different to the proposed design would create additional environmental impacts. Dissipator
pads are shown at the crossings to help minimize/eliminate any potential erosion concerns.
All work will be conducted in accordance with all local state and federal regulations. No BMPs are required for
the proposed project. Please see the attached project plans. Traditional equipment will be used consisting of
front-end loaders, bulldozers, paving equipment, graders, and earth movers.

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:*
Impacts to jurisdictional features have been avoided and minimized to the maximum
extent practicable by incorporating resourceful site planning, including the utilization of
the wetland and stream delineation to adjust the project layout in order to avoid and
minimize impacts. The proposed stream and associated buffer impacts are the result of
the necessary infrastructure and facility layout, without which the project's goals would
not be realized. The stream/buffer impacts at Crossing #1 are required to connect the
project to the larger development.
Stream/buffer impact Crossing #2 are required to gain access to the southern section of
the project site as this section is surrounded by undeveloped forested land and there are
no other existing road for it to connect to.
Stream/buffer impacts at Crossing #3 are required to gain access to the northeastern
section of the project site, as an additional entryway from New Bethel Church Road would
be located significantly closer than the NCDOT and Garner intersection spacing

10/31/2019 Submission Completed
requirements for safe stopping distances and required connectivity (potentially causing a
traffic hazard if constructed).
Additional Zone 2 buffer impacts at Crossing #3 are required for construction of an
underground sanitary sewer easement, due to elevation requirements preventing the
utility line beneath the proposed road, which would render the utility line ineffective. The
Utility Crossing will involve clearing for directional boring within portions of buffer Zone 2.
Impacts to the stream and Zone 1 will be avoided as the utility line will be bored beneath
these areas, avoiding any aboveground disturbance.
Temporary Impacts at the Water Main Zone to the perennial stream, a portion of Zone 1,
and a portion of Zone 2 are required due to the steep slope of the area, which prevents
the safe use of the equipment required for directional boring. Upon completion of the
temporary impacts, the streambed will be restored to pre -project elevations and widths
using natural streambed material. The trench will be backfilled with the excavated natural
streambed material to a depth of at least 12-inches or bottom depth of impacted area is
shallower. Stream banks will be restored to pre -project grade and contours. Disturbed
portions of Zone 1 and Zone 2 will be seeded and stabilized immediately following
disturbance.
The location of the proposed road crossings have been minimized impacts to the
maximum extent practicable by aligning the crossing as close to 90 degrees as possible.
In addition, utilities (i.e. water) and sidewalks have been aligned adjacent and parallel to
the proposed road crossings. Dissipater pads associated with the culverts will be installed
flush with the existing grade of the stream bed to allow for aquatic life passage.
The proposed pipe orientation is as close to the existing stream alignment as possible
with the least amount of environmental impacts. Due to how the existing stream
alignment meanders, realigning the culverts will create additional environmental impacts.
Dissipator pads are shown at the crossing to help minimize/eliminate any potential
erosion concerns.
Access to the adjoining properties to the east and south were unavailable as they are
owned by other entities. Therefore, alternative access routes could not be obtained and
Crossings #2 and #3 were required.

1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques: *
Proper land use control measures will be utilized during all phases of construction and
will be in compliance with applicable regulations. All work will take place during dry
conditions and can be facilitated from upland, non -jurisdictional, stable ground. Measures
will be taken to prevent oil, tar, trash, debris, and other pollutants from entering the
adjacent jurisdictional streams and buffer areas. Any excess excavated materials not
utilized as backfill will be placed and contained within upland areas and
permanently stabilized to prevent erosion into adjacent jurisdictional streams and buffer
areas. Therefore, stockpiling of excavated material within jurisdictional areas will be
strictly prohibited as part of the construction of this project. All project construction
activities initiated within jurisdictional streams and buffers will be carried to completion in
an expeditious manner to minimize the period of disturbance within the jurisdictional
streams.

Timmons Group contacted three mitigation banks associated with the project HUC (RES,
Wildlands, and Restoration Systems), however, none of the banks had available stream
mitigation. Therefore, a Letter of Acceptance was obtained from the NC DEQ Department
of Mitigation Services for the required mitigation.
The proposed Neuse River Buffer Impacts are either exempt or allowable use activities.
Therefore, buffer impact mitigation is not required.
F. Stormwater Management and Diffuse Flow Plan (required
by DWR)
*** Recent changes to the stormwater rules have required updates to this section .***
1. Diffuse Flow Plan
la. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC
Riparian Buffer Protection Rules?
Yes
No
1 b. All buffer impacts and high ground impacts require diffuse flow or other form of stormwater treatment. If
the project is subject to a state implemented riparian buffer protection program, include a plan that fully
documents how diffuse flow will be maintained.
All Stormwater Control Measures (SCM)s must be designed in accordance with the NC Stormwater Design
Manual. Associated supplement forms and other documentation shall be provided.

What type of SCM are you providing?
Level Spreader
Vegetated Conveyance (lower SHWT)
Wetland Swale (higher SHWT)
Other SCM that removes minimum 30% nitrogen
Proposed project will not create concentrated stormwater flow through the buffer
(check all that apply)

2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
Yes No
2b. Does this project meet the requirements for low density projects as defined in 15A NCAC 02H .1003(2)?*
IY�R.7
To look up low density requirement click here 15A NCAC 02H .1003(2).
Comments:
The proposed development has been evaluated to ensure that the proposed site development will meet or
exceed the intent of the Town of Garner's stormwater requirements for stormwater quality and control. Due to
the geographical location of the proposed development, the site must meet nitrogen runoff requirements.
Based on the current design, and the fact that the site is limited to 30% impervious, the nitrogen runoff
requirements can be met via a buydown and there will be no need to install water quality measures for
treatment. In addition, the site was evaluated to determine if, due to location within the watershed, detention
would be beneficial or detrimental to downstream flooding. As per an analysis of stormwater detention, it was
determined that detention would not be beneficial to this project and would result in adverse impacts
downstream; therefore, detention facilities are not included in the proposed project.

Yes No
5i. Does this project involve (1) blasting, and/or (2) other percussive activities that will be conducted by
machines, such as jackhammers, mechanized pile drivers, etc.?*
Yes No
5j. What data sources did you use to determine whether your site would impact Endangered Species or
Designated Critical Habitat?*
The NC Natural Heritage Program and IPaC databases were used to determine whether
or not any federally protected species have been known to occur within the project limits.
An aquatic species survey report was prepared by Three Oaks Engineering for Timmons
Group to determine the presence of any federally protected aquatic species within the
project limits. The Aquatics Survey determined the project would "not likely adversely
affect" protected species, and Kathy Matthews of the USFWS informally concurred with
that determination on 9/26/19.
