SECTION B — PROJECT INFORMATION AND PRIOR PROJECT HISTORY
PART 3. PROJECT DESCRIPTION
3a. Proiect Description:
The project site is located within the Brentwood Estate Subdivision in Raleigh, North Carolina. An
unnamed tributary (UT) to Marsh Creek runs through the South of property located at 3300 Vinson ct. The
park currently consists of multipurpose fields, tennis courts, basketball courts, a playground, an open field,
and walking trails served by a restroom facility, maintenance facility, and a parking lot. The park lies on
two City -owned adjacent parcels that are to be recombined into a single parcel. Adjacent land uses include
acre lots around the north, south, and west and an elementary school to the east. A.public sanitary
sewer main outfall is located along the eastern edge of the park along the bank of Marsh Creek.
The project involves upgrades to an existing park built in the 70's to provide an improved playground, new
picnic shelter, and new public restrooms. These improvements will include a reduction in the current
parking lot size, new water lines, an upgraded sewer service, and re -paving.
3d. Explain the Purpose of the Proiect:
` The purpose of the project is to provide needed upgrades to an existing ark facility. The impacts that
p p p 1 P pg g P Y p
will occur on the stream and associated buffers are to repair a small section of stream with existing bank
erosion and the replacement of an existing sanitary sewer service.
The purpose of the stream bank work is to repair active Erosion that is occurring on the north stream bank
just below the existing parking area to prevent additional sediment entering the stream. The purpose of
the sanitary sewer service replacement is to upgrade the existing pipe to current City of Raleigh standards.
3e. Describe the Overall Proiect in Detail, Including the Type of Equipment to be Used:
Removal of Impervious area (Paved Parking Lot):
The stream bank corridor within the repair area will be re -vegetated along North bank of the stream.
About 701f of impervious Driveway (Parking lot) is proposed to be removed and the area will be regraded
and reshaped to be stabilized with vegetated filter strips. This will reduce the runoff erosion potential by
spreading over wide vegetated area before concentrated flow is formed. A total of 4175 sqft of
impervious parking area will be converted to vegetated filter strip. This design will add 2190 sqft of
- additional vegetated buffer area to the stream buffer which was previously an impervious parking area.
g
No SCM's were required to control nitrogen export for the site. These measures are being install only as
an opportunity to provide aid in better water quality exiting the site.
Stream Bank Stabilization:
An existing curb cut in the parking lot currently concentrates stormwater runoff to one location. The
runoff leaving the parking lot has eroded a channel through the steep stream embankment causing bank
erosion with significant soil loss and migration towards the parking lot. Through the improvements to the
park the existing parking lot paving within Zone 1 & 2 of the buffers will be removed. Sheet flow off the
1
_ Timmons Group Brentwood Park Improvements, 3315 Vinson Court
Supplemental Information, PCN Applications
parking area through a gravel verge is planned for the improvements. The proposed measures will
minimize erosive power of the runoff by spreading over a wide area through grading and provision of
vegetated filleter trips.
The incised channel and banks will be repaired with fill, matted and replanted. A rock toe has been
designed at the bottom of the fill to re-establish the channel toe and secure the proposed embankment
fill. The stream bank corridor within the repair area will be re -vegetated with both herbaceous and woody
species. The re -introduction of vegetation to the repair area will aid in providing long term bank stability.
The stabilized banks and re -vegetated corridor will additionally provide stormwater quality benefits.
Service Sewer Relocation
An existing sanitary sewer lateral crosses UT to Marsh Creek. The lateral is being brought up to current
City of Raleigh Standards to service the restrooms and new playground planned for these renovations.
The sewer line will be replaced in the existing location crossing the stream.
Proposed Equipment
The equipment to be used in the project is earth moving equipment and various other support
apparatuses. The stream normal flow will be pumped around the project site. Stabilization will occur daily
within the work area. Heavy equipment may include hydraulic excavator, compactors, bulldozers,
U�
skidsteer loaders, and dump trucks to load and unload materials. The construction equipment will enter
the site through Parking Lot side from Vinson Court Driveway. All construction will be performed within
the defined limit of disturbance.
SECTION C — PROPOSED IMPACTS INVENTORY
3i. Stream Impacts:
S1: Permanent Stream stabilization will be provided on the North side bank through filling and grading to
match existing bank grades, rock toe reinforcement in the fill area, and installation of erosion control
mating.
S2: Stream banks will be temporary disturbed for construction of aerial sewer crossing service sewer
replacement.
6i. Buffer Impacts:
B1: This area will be impacted due to construction access and re -grading operations to reconstruct the
bank on the North and South sides of the stream. The buffers will be re-established with vegetation as
�I shown on the construction plans.
SECTION D —IMPACT JUSTIFICATION AND MITIGATION
Ia. Specifically describe measures taken to avoid or minimize the proposed impacts in designing
rp oject.
__. This project is necessary due to improve water quality by repairing the eroded stream bank and preventing
additional sediment transport into the stream.
2
Timmons Group Brentwood Park Improvements, 3315 Vinson Court
Supplemental Information, PCN Applications
i
To provide long term stability the improvements have provided sheet flow from the parking lot into a
- vegetated filter strip prior to stormwater entering the stream. The sheet flow will provide better stability
for stormwater running down the terrace embankment to the stream.
Proposed impacts have been minimized for the stream crossing s the replaced pipe will be installed in the
current location. The limits of disturbance have been minimized to only the area needed to construct the
repairs. Impacts to the stream buffer will be minimized by accessing the site through a narrow corridor
and protection of as much existing vegetation as possible.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through
construction techniques.
Pumping of normal stream flow be maintained and pumped around the site during construction activities.
Bank stabilization, coveringthe slope with riparian seed and coir matting, erosion control mating will occur
daily upon completion of bank grading.
SECTION F — SUPPLEMENTARY INFORMATION
Sd. What data sources did you use to determine whether your site would impact Endangered Species
or Designated Critical Habitat?
The site is an existing urban residential area that has been previously impacted by development. Open
areas are currently being mowed and maintained. Habitat is not present for Wake County listed vertebrate
and invertebrate endangered species with the exception of Northern Long Eared Bats. It is not anticipated
that this tree removal would be an impact to critical habitat for the Northern Long Eared Bat in Wake
County. Therefore, it is not anticipated that there will be any adverse impacts associated with T/E species.

Re: Environmental Assessment Results 19-024
Brentwood Park Aerial Sewer Crossing
City of Raleigh, Wake County, NC
Dear Mindy:
This letter provides a summary of the results of an Axiom Environmental, Inc. (Axiom) investigation
associated with a proposed aerial sewer crossing an unnamed tributary to Marsh Creek at Brentwood
Park in Raleigh (Figure 1). The approximately 0.16-acre study area, bounded by the red line on the
attached Figure 2, was created from information presented on the Utility Sheet provided as an e-mail
attachment on September 16, 2019.
Axiom biologists conducted a field visit on December 10, 2019 to perform a general environmental
investigation, a Section 404 jurisdictional area delineation, and a federally protected species
investigation. Forms documenting our findings are attached to this summary letter.
Site Description
Brentwood Park is located in the Piedmont physiographic region of the state in the Neuse River
Basin. The study area, located in the western portion of the park, includes a perennial stream within
a mesic pine/mixed hardwood forest. Both stream banks slope steeply down to the stream. Rip -rap
has been placed adjacent to the parking lot in the northwestern portion of the study area. In general,
vegetation is characterized by a closed mature canopy composed of sweetgum (Liquidambar
styraciflua), red oak (Quercus rubra), loblolly pine (Pinus taeda), red maple (Acer rubrum), and
white oak (Q. alba). The shrub and herb/vine layers are dominated by exotic species such as
Japanese privet (Ligustrum japonicum), Chinese privet (Ligustrum sinense), Oregon grape (Mahonia
aquifolium), Nandina (Nandina domestica), English ivy (Hedera helix), and Japanese honeysuckle
(Lonicera japonica).

Section 404 Jurisdictional Area Delineation Results
Streams
An unnamed tributary to Marsh Creek, Stream SA, was identified as the only jurisdictional feature
within the study area (Figure 2). Approximately 96 feet of Stream SA flows through the study area
from west to east. This reach of stream is incised and is characterized by steep banks and excessive
r sedimentation in the streambed. An aerial sewer line crossing the stream can be seen in the photo
on the attached Figure 2. The North Carolina Stream Assessment Method (NC SAM) form rates
this stream as a Medium. The left and right banks of Stream SA were marked with enumerated
blue and orange flagging, and flag locations were recorded using a GPS with reported sub -meter
accuracy. A shapefile of this feature is attached with this summary.
Wetlands
No wetlands were identified within the study area.
Neuse River Riparian Buffer
According to the Neuse River Riparian Buffer Rules, any surface water depicted on either the most
recent version of the Natural Resources Conservation Service (NRCS) county soil survey or the most
recent version of the U.S. Geological Survey (USGS) 7.5-minute quadrangle is subject to the buffer
requirements. This 50-foot riparian buffer is in effect for the depicted feature until a representative
of the N.C. Division of Water Resources (NCDWR) confirms the feature is not present.
Stream SA is depicted on the soil survey of Wake County (Figure 3). An evaluation of this stream
using the NCDWQ Stream Identification Form (Version 4.11; see attached) determined that this
stream is perennial and is therefore subject to the buffer rules.
Federally Threatened and Protected Species
Based on the most recently updated county -by -county database of federally listed species in North
Carolina as posted by the U.S. Fish and Wildlife Service (USFWS) and updated June 27, 2018, the
bald eagle and six federally protected species are listed for Wake County. Table 1 lists these species
and indicates if potential habitat exists within the study area.

Bald Eagle
Habitat for 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. Suitable habitat for bald eagle does not occur within the study area; therefore, the proposed
project will have No Effect on bald eagle. In addition, the North Carolina Natural Heritage Program
(NCNHP) has no documentation of this species within 1:0 mile of the study area.
Cape Fear shiner
The Cape Fear shiner occurs only in the Cape Fear River basin. Since the project is located in the
Neuse River basin, the proposed project will have No Effect on Cape Fear shiner. In addition, the
NCNHP has no documentation of this species within 1.0 mile of the study area.
Dwarf Wedgemussel
Suitable habitat for dwarf wedgemussel does not occur within the study area: therefore, the proposed
project will have No Effect on dwarf wedgemussel. In addition, the NCNHP has no documentation
of this species within 1.0 mile of the study area.

Tar River spinymussel
Suitable habitat for Tar River spinymussel does not occur within the study area; therefore, the
proposed project will have No Effect on Tar River spinymussel. In addition, the NCNHP has no
documentation of this species within 1.0 mile of the study area.
Yellow Lance
-' Suitable habitat for yellow lance does not occur within the study area: therefore, the proposed project
will have No Effect on yellow lance. In addition, the NCNHP has no documentation of this species
within 1.0 mile of the study area.
Michaux's Sumac
Suitable habitat for Michaux's sumac occurs along the woodland edges and open areas adjacent to
the stream. The survey window for this species is May through October. During this December site
visit, systematic surveys of this area found no evidence of this species. A previous investigation of
this area conducted during the 2017 survey window identified no individuals. The NCNHP has no
documentation of Michaux's sumac within 1.0 mile of the study area; therefore, the proposed project
will have No Effect on Michaux's sumac.
Please let me know if you have any questions about this information. We appreciate the opportunity
to assist with this project.
Yours truly,

RE: Brentwood Park; 19-024
Dear Allison Keith:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached 'Documented Occurrences' tables and map.
The attached 'Potential Occurrences' table summarizes rare species and natural communities that
have been documented within a one -mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one -mile
radius of the project area, if any, are also included in this report.
If a Federally -listed species is documented within the project area or indicated within a one -mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
httos://www.fws.aov/off ices/Di rectory/Li stOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water
Management Trust Fund easement, or an occurrence of a Federally -listed species is documented
near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at rodnev.butler(ancdcr.aov or 919-707-8603.
Sincerely,
NC Natural Heritage Program

No Element Occurrences are Documented within the Project Area
There are no documented element occurrences (of medium to very high accuracy) that intersect with the project area. Please note, however, that althou�
NCNHP database does not show records for rare species within the project area, it does not necessarily mean that they are not present; it may simply me
the area has not been surveyed. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the I
area contains suitable habitat for rare species. If rare species are found, the NCNHP would appreciate receiving this information so that we may update o
database.
