Dear Ms. Higgins:
On behalf of Southbridge Fellowship Church, we are applying for an NC
Division of Water Quality (DWQ) General Water Quality Certification (GC)
3890 and IWGP 100000 for permanent impacts to isolated and riparian
wetlands associated with construction of Southbridge Fellowship Church. The
subject property is + 10.78 acres in size and is located at 10931 Glenwood
Avenue on the south side of U.S. Hwy. 70 east, just east of the Durham 1
Wake County line, in Raleigh, Wake County, within the Neuse River Basin of
North Carolina.

WETLAND/STREAM MAPPING: The streams and wetlands were verified
by Mr. Craig Brown of the USACE on April 17, 2012, and a Neuse River
Riparian Buffer determination was conducted by Mr. Martin Richmond on
April 17, 2012 (NBRRO # 12 -161 enclosed). The proposed project drains to
Brier Creek, a tributary of the Neuse River Basin and a designated Class
CINSW, and subject to the Neuse River Buffer Rules. There is one
Research Triangle Park, NC
unimportant intermittent tributary (Stream A), which runs through the
Post OMCB Box 14005
property approximately 324 linear feet and one important perennial tributary
Reseaeh Triangle Park,
(Stream B) which runs 47 linear feet across the northeast corner of the
North Carolina 27709
property and ultimately drains to Brier Creek, and the Neuse River (HUC
2905 Meridian Parkway
Durham, North Carolina 27713
03020201). Stream Feature "B" is depicted on the Wake County Soils

Wetlands do exist within the project area, and while it is the intent of the
church to avoid significant impacts to wetlands, streams or other
environmentally sensitive features, there are proposed impacts to 0.04 acre of
Isolated Wetlands and 0.01 acre of jurisdictional riparian wetlands. There are
no stream impacts or Neuse Buffer impacts associated with the proposed
project.
Inset 1: There are proposed impacts to two isolated wetlands B and C
associated with a stormwater BMP and a small portion of wetland C
associated with providing access to the facilities. The proposed development
is located within the Neuse River basin and will be subject to the stormwater
management requirements set forth in Section 10, Chapter 9 of the City of
Raleigh regulations. Per City of Raleigh regulations, stormwater management
on this site shall address two primary issues: (1) peak discharge rates and (2)
water quality management, and will employ a stormwater wetland facilities to
meet these requirements. Since the site will be required to provide 85% TSS
for all impervious surfaces, two stormwater management facilities are
proposed for the project; a constructed wetland for Sub -Basin 1 and a
bioretention area for Sub -Basin 2. Stream "A" is not subject to the Neuse
River Riparian Buffer Rules therefore while the discharge from the
bioretention area will be diffuse, diffuse flow was not addressed.
Inset 2: To provide access to the front portion of the building and to allow for
ingress and egress of emergency vehicles using driveway, there is a retaining
wall proposed in order to construct the driveway and avoid impacts to Stream
"A ". However, there is a minimal amount of clearing and grading proposed
along the edge of wetland "A" associated with the installation of the retaining
wail (Fig. 4 ).This wetland area is mostly shrub /herbaceous with a few larger
trees, and has likely been timbered in the last 30 years. It should be noted that
the church proposing at least one acre dedicated to a tree conservation area on
the western end of the property.
Typical construction equipment will be used such as a long -arm track -hoe,
front end loader, and bush hog for the initial clearing.

AVOIDANCE and MINIMIZATION: Stream and Buffer impacts have
been avoided to the greatest extent practicable, while achieving a successful
project. Wetlands do exist within the project area, and while it is the intent of
the church to avoid significant impacts to wetlands, streams or other
environmentally sensitive features, there are proposed impacts to 0.04 acre of
Low Quality Isolated Wetlands and 0.01 acre of jurisdictional riparian
wetlands.
To provide access to the front portion of the building and to allow for ingress
and egress of emergency vehicles using driveway, there is a retaining wall
proposed in order to construct the driveway and avoid impacts to Stream "A ".
Using this retaining wall completely avoids impacting Stream "A ". Only the
minimal amount of wetland area will be impacted for safe construction and
installation of the retaining wall, and temporary impacts to the stream bed
itself will be avoided during construction. This wetland area is mostly
shrub /herbaceous with a few larger trees, and has likely been timbered in the
last 30 years. It should be noted that the church proposing at least one acre
dedicated to a tree conservation area on the western end of the property.
DIFFUSE FLOW: Since the proposed project is located within the Neuse
River Basin, it is subject to the diffuse flow requirements, however neither
stormwater BMP outlets to or near a buffered stream feature. Stream "A" is
not subject to the Neuse River Riparian Buffer Rules therefore while the
discharge from the bioreterntion area will be diffuse, diffuse flow was not
addressed. The constructed wetland BMP, outlets to over 500 feet of low

gradient upland area and into a ditch network along Hwy 70. Therefore a
diffuse flow plan is not included.
STORMWATER MANAGEMENT: Since the site will be required to
provide 85% TSS for all impervious surfaces, two stormwater management
facilities are proposed for the project; a constructed wetland for Sub -Basin 1
and a bioretention area for Sub -Basin 2.
Constructed Wetland
The proposed constructed wetland is to be along the east property line and
provide both peak flow rate detention and water quality (TSS and N). The
proposed facility has some walls to accommodate the grading. The dam is
proposed to have 3(H ):1(V) slopes with a 10' top width. An access route to
the dam is provided from the south of the project. The spillway acts as both a
principal and emergency spillway system with just under a foot of freeboard
in the 100 -year, worst -case scenario. The proposed normal pool elevation is
395 with an orifice at invert 395 to accommodate the 1" runoff volume over
one vertical foot. The surface area of the facility was preliminarily sized
based on this one vertical foot ponding of the 1" runoff volume. Final
grading, details, and specifications will be provided through the City of
Raleigh permitting process for the facility.
Bioretention Area
The proposed bioretention area is located to the west of the proposed entrance
drive off of Glenwood Avenue. The facility is designed to capture the
majority of the driveway for N and TSS removal. The preliminary sizing of
the facility is based on the 1" runoff volume and a 9" ponding depth for the
water quality function. The facility is mostly in cut with a 5' wide berm "top"
provided. For this preliminary analysis, no peak flow rate detention benefit
was assumed for the bioretention area. Final grading, details, and
specifications will be provided through the City of Raleigh permitting process
for the facility.
A detailed report has been submitted to the City of Raleigh with final
hydrologic and hydraulic calculations detailing the expected stormwater
impacts as a result of the proposed development, including final design of the
proposed stormwater wetland facility and bioretention area that will be used to
treat the site. Enclosed is a copy of the SW notebook with detail sheets.
MITIGATION: Combined wetland impacts (isolated and 4041401)
combined are below 0.10 -acre, and the applicant is avoiding impacts to
Stream "A" completely but installation of a retaining wall; therefore no
mitigation is proposed at this time.

Project Description
3a.
Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
The subject property is ± 10.78 acres in size and is located at 10931 Glenwood Avenue on the south side
of U.S. Hwy. 70 east, just east of the Durham 1 Wake County line, in Raleigh, Wake County, North
Carolina. (PIN Number: 0759815591). The subject contains a residential structure and four (4) wooden
sheds, all of which are in degraded conditions. The majority of the subject property consists of forested
and cleared land. The subject property is bordered to the west, south, and east are forested land and to
the north by Glenwood Avenue
Approximately 20 percent of the subject property is comprised of forested areas and would be generally
characterized as a Dry Mesic Oak- Hickory Forest (Schafale and Weakley, 1990), while 10 percent can be
characterized as a maintained/disturbed land. The property is located within the Triassic Basin, a unique
geologic area of the eastern Piedmont Region of North Carolina. The Soil Survey of Wake County,
North Carolina (Soil Conservation Service, 1970) lists the soils within the subject property area as
Mayodan sandy loam and Creedmoor sandy loam (Figure 2). The proposed project drains to Brier Creek,
a tributary of the Neuse River Basin and a designated Class CINSW, and subject to the Neuse River
Buffer Rules. There is one unimportant intermittent tributary (Stream A), which runs through the
property approximately 324 linear feet and one important perennial tributary (Stream B) which runs 47
linear feet across the northeast corner of the property and ultimately drains to Brier Creek, and the Neuse
River. Stream Feature "B" is depicted on the Wake County Soils Survey, and is therefore subject to the
Neuse River Riparian Buffer Rules. Stream Feature "C" depicted on the DWQ Neuse Buffer
Determination Letter dated August 21, 2012, was deemed an isolated wetland feature (Wetland C), and is
therefore not subject to the Neuse River Riparian Buffer Rules (NBRR0 4 12-161). There is one
jurisdictional 404 /401 riparian wetland (Wetland A: 0.05 acre), at the head of Stream A, and two isolated
401 wetland pockets in the central and western portions of the property (Wetland B: 0.03 acre/ Wetland
C: 0.01 acre).
The streams and wetlands were verified by Mr. Craig Brown of the USAGE on April 17, 2012, and a
Neuse River Riparian Buffer determination was conducted by Mr. Martin Richmond on April 17, 2012
(NBRRO # 12 -181 enclosed).
Land use within the vicinity of the project is a mix of retail /commercial, multi - family, and single - family
residential, office, and natural forested areas adjacent to the project area. RDU International Airport is to
the southeast of the property boundary.

3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Intermittent Stream A: 324 If 1 Perennial Stream B: 47 if
3d. Explain the purpose of the proposed project:
The purpose of the proposed project is to provide a place of worship for the members of Southbridge Fellowship Church.
3e. Describe the overall project in detail, including the type of equipment to be used:
The proposed project consists of a church, a youth center, associated utilities, parking, ingress, egress from
the site, and other improvements. The property is located in the Neuse River Basin, but not in the Falls Lake
Watershed. The proposed project will require permitting for impacts with the North Carolina Division of
Water Quality and US Army Corps of Engineers. The proposed project will require a Stormwater
Management Plan and therefore 85% TSS Removal for all impervious surfaces. Sine the City of Raleigh is
a delegated authority for NC DWQ Stormwater Management Plans, the review and approval of the SWMP
will be part of the City of Raleigh review process.
Proposed Impacts:
Wetlands do exist within the project area, and while it is the intent of the church to avoid significant impacts
to wetlands, streams or other environmentally sensitive features, there are proposed impacts to 0.04 acre of
Isolated Wetlands and 0.01 acre of jurisdictional riparian wetlands.
Inset 1: There are proposed impacts to two isolated wetlands B and C associated with a stormwater BMP and
a small portion of wetland C associated with providing access to the facilities. The proposed development is
located within the Neuse River basin and will be subject to the stormwater management requirements set forth in
Section 10, Chapter 9 of the City of Raleigh regulations. Per City of Raleigh regulations, stormwater management on
this site shall address two primary issues: (1) peak discharge rates and (2) water quality management, and will employ a
stormwater wetland facilities to meet these requirements. Since the site will be required to provide 85% TSS for all
impervious surfaces, two stormwater management facilities are proposed for the project; a constructed wetland for Sub -
Basin 1 and a bioretention area for Sub -Basin 2. Stream "A" is not subject to the Neuse River Riparian Buffer Rules
therefore while the discharge from the bioretention area will be diffuse, diffuse flow was not addressed.
Inset 2: To provide access to the front portion of the building and to allow for ingress and egress of
emergency vehicles using driveway, there is a retaining wall proposed in order to construct the driveway and
avoid impacts to Stream "A ". However, there is a minimal amount of clearing and grading proposed along
the edge of wetland "A" associated with the installation of the retaining wall (Fig. 4).This wetland area is
mostly shrub/herbaceous with a few larger trees, and has likely been timbered in the last 30 years. It should
be noted that the church proposing at least one acre dedicated to a tree conservation area on the western end
of the property.
Typical construction equipment will be used such as a long -arm track -hoe, front end loader, and bush hog for
the initial clearing.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stream and Buffer impacts have been avoided to the greatest extent practicable, while achieving a successful
project. Wetlands do exist within the project area, and while it is the intent of the church to avoid significant
impacts to wetlands, streams or other environmentally sensitive features, there are proposed impacts to 0.04
acre of Low Quality Isolated Wetlands and 0.01 acre of jurisdictional riparian wetlands.
To provide access to the front portion of the building and to allow for ingress and egress of emergency
vehicles using driveway, there is a retaining wall proposed in order to construct the driveway and avoid
impacts to Stream "A ". Using this retaining wall completely avoids impacting Stream "A ". Only the minimal
amount of wetland area will be impacted for safe construction and installation of the retaining wall, and
temporary impacts to the stream bed itself will be avoided during construction. This wetland area is mostly
shrub/herbaceous with a few larger trees, and has likely been timbered in the last 30 years. It should be noted
that the church proposing at least one acre dedicated to a tree conservation area on the western end of the
property.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation
as described in the Erosion Control Plan sheet reviewed and approved by the NC Division of Land Quality and City
of Raleigh. All work will take place during dry conditions and can be facilitated from high, non jurisdictional,
stable ground adjacent to the Neuse Buffer. The contractor shall install silt fence, inlet protection, sediment traps,
diversion ditches, tree protection, clearing only as necessary to install these devices. All erosion and sediment
control measures will be checked for stability and operation following every runoff producing rainfall , but in no
case less than once every week. Any needed repairs will be made immediately to maintain all measures designed.
An erosion control inspections report is required and will be kept by the owner's representative.
The project will meet all relative requirements of Best Management Practices and Engineered Stormwater Control
Structures as outlined through State and Local Stormwater Rules.

® Yes ❑ No
within one of the NC Riparian Buffer Protection Rules?
1 b. If yes, then is a diffuse flow plan included? If no, explain why.
comments: Since the proposed project is located within the Neuse River
Basin, it is subject to the diffuse flow requirements, however neither
stormwater BMP outlets to or near a buffered stream feature. Stream "A" is
not subject to the Neuse River Riparian Buffer Rules therefore while the
discharge from the bioretention area will be diffuse, diffuse flow was not
El Yes ®No
addressed. The constructed wetland BMP, outlets to over 500 feet of low
gradient upland area and into a ditch network along Hwy 70. Therefore a
diffuse flow plan is not included.

2d. If this project DOES require a Stormwater Management Plan, then provide a brief, narrative description of the plan:
Proposed Stormwater Management Facilities
Since the site will be required to provide 85% TSS for all impervious surfaces, two stormwater management
facilities are proposed for the project; a constructed wetland for Sub -Basin 1 and a bioretention area for Sub -
Basin 2.
Constructed Wetland
The proposed constructed wetland is to be along the east property line and provide both peak flow rate
detention and water quality (TSS and N). The proposed facility has some wails to accommodate the grading.
The dam is proposed to have 3(H):1(V) slopes with a 10' top width. An access route to the dam is provided
from the south of the project. The spillway acts as both a principal and emergency spillway system with just
under a foot of freeboard in the 100 -year, worst -case scenario. The proposed normal pool elevation is 395
with an orifice at invert 396 to accommodate the 1" runoff volume over one vertical foot. The surface area of
the facility was preliminarily sized based on this one vertical foot ponding of the 1" runoff volume. Final
grading, details, and specifications will be provided through the City of Raleigh permitting process for the
facility.
Bioretention Area
The proposed bioretention area is located to the west of the proposed entrance drive off of Glenwood Avenue.
The facility is designed to capture the majority of the driveway for N and TSS removal. The preliminary
sizing of the facility is based on the 1" runoff volume and a 9" ponding depth for the water quality function.
The facility is mostly in cut with a 5' wide berm "top" provided. For this preliminary analysis, no peak flow
rate detention benefit was assumed for the bioretention area. Final grading, details, and specifications will be
provided through the City of Raleigh permitting process for the facility.
Please note that there is a small remaining area of the proposed entrance drive than cannot physically be
treated in either the constructed wetland or bioretention area. This area is considered bypass. Therefore the
85% TSS removal is to the maximum extent practical for the site.

(i) Erosion and sediment control plans;
(ii) Installation and planting schedules for the proposed BMPs;
(iii) Appropriately scaled plan views and cross sectional details of all
BMPs and associated components -- inlet and outlet structures,
forebay, respective zones and pertinent elevations.
If your project is located within a State implemented Riparian Buffer Rule Area, submit the
following along with site plans and PCN form:
1) Three (3) copies of the details for on -site diffuse flow provisions, (refer to
http://h2o.enr.state.nc.us/su/bmp_forms.htm).
DWQ Stream Determination Forms for streams on property and DWQ determination
letter for wetlands or streams (if applicable). �i G 6 � � U t� 11 _ 4,/
The following is the most critical of all the information that you must provide, The quality and
detail of the information will often determine the expeditiousness of the review. The following is
a checklist of the types of pertinent information required at a minimum:
Maps and Plans:
The most recent version of the 1:24,000 USGS Topographic Map - Please cleanly draw or
deli Bate the site boundaries on the topographic map.
El The most recent version of the bound and published County NRCS Soil Survey Map -
(required for projects within the Neuse River Basin, Tar - Pamlico River Basin, Randleman
Lake Watershed and the Catawba River Basin, also recommended for all projects) -
Please clearly delineate the site boundaries, etc. on the map. If the delineation obscures
any of the features, it is recommended that a clean copy be provided. Copies of the
Version 1.4
January 9, 2009
current soil survey andlor soil survey map sheets can be obtained from the local NRCS
County Office (http: / /www.nc.nres.usda.go ). GIS soil layers are not acceptable.
Vicinity map - Please clearly mark the location and approximate boundaries of the property
and project on the map. Please indicate north arrow and scale. Please include applicable
road names or State Road numbers.
The Site Plan - The most critical map to be provided is the site plan. You must provide full
sized plans. The following is the minimum list of plans that are typically needed.
Pre - construction /Pre- existing conditions - This sheet (or sheets) must include:
• All jurisdictional and non jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Topographic contours with elevations
• Any existing structures and impervious areas
• Existing utility lines and easements
• Existing roads, culverts, and other pertinent features
• North arrow and the scale (1 ":50' scale is recommended).
Proposed conditions - This sheet (or sheets) must include:
• All jurisdictional and non jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Lot layout (if a subdivision or commercial development is proposed) - lots must be
developable without further impacts to murisdictional and non- murisdictional wetlands
streams water features and State regulated buffers. Building envelopes must be
provided when streams, wetlands, riparian buffers, or water features exist on a lot
• All built -out structures and impervious cover
• Final grading contours with elevations
• All utilities and easements (including septic fields on all lots within 100 feet of stream,
wetland, or water features - if applicable)
• Impacted areas -- these should correspond with the Impact numbers listed on your PCN
form.
- 15ainage Plans - Final drainage plans must include the following:;,, Sw /V# 44666
• Locations and pertinent elevations and sizes of the stormwater collection system and
drainage ways
• All inlets and outlets must also be shown with pertinent elevations (All outlets to
wetlands must be at a non- erosive velocity, generally less than 2 ft/sec durin g the peak
flow from the 10 -yr storm)
• Scaled stormwater BMPs must also be indicated as required by OWQ rules and policies
• In certain cases (see Section E of PCN form), final stormwater management plans must
also be provided (see Stormwater Management Plan Checklist)
2--proposed Impacts - All impacts to jurisdictional and non - jurisdictional wetland, stream,
water features, and State regulated buffers must be shown and labeled on the site plans at
a scale no smaller than 1" = 50'. Al excavation, fill, flooding, stabilization, and other impacts
that will be conducted in or near jurisdictional and non - jurisdictional wetland, stream, water
features, and State regulated buffers must be indicated. Please provide cross sectional
details showing the provisions for aquatic life passage (burial of culvert 20% for culverts r 48
inches, and 1 -foot for culverts > 48 inches).
Version 1.4
January 9, 2009
Wetland Impacts:
Precise grading and final elevation contours must be provided. Existing
vegetation and any clearing must be specified.
Er All subsurface utility lines must indicate the location of anti -seep collars.
Construction detail for anti -seep collars must be provided.
❑dway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
Plans should show that the hydrology of remaining wetlands on the site will be
maintained.
Stream Impacts:
Stream impacts must be clearly shown on the plans. The centerline as well as
the banks of the stream must be surveyed or located by GPS for the portion of
the stream to be impacted.
—�® The inlet and the outlet of all culverts should be aligned with the stream as
much as possible. Inlet and outlet elevations and streambed elevations should
be indicated. Any inlet or outlet protection must be shown and enumerated on
the impact map(s).
" For bottomless culverts or other spans, a vertical cross section should be
provided that shows the minimum distance from each span to each stream bank,
the stream cross section, the height of the span above the stream and the
minimum distance from the edge of each footer to each stream bank.
Additionally, please provide a signed and sealed geotechnical report of
subsurface soils at the proposed bottomless culvert location. The report must
comply with the Division of Highways — Guidelines for Drainage Studies and
Hydraulic Design, prepared by A.L. Hankins, Jr., State Hydraulics Engineer -
1999.
cE Multiple culverts or sectioned box culverts typically require the use of sills, off-
setting or other means to match the cross section of the existing stream (in order
to maintain stream stability and provide aquatic life passage). A vertical cross
section of the culverts should be shown overlain with the up and downstream
stream cross section including the stream flood -prone area.
--E5-- Impacts associated with dam construction must indicate and enumerate all fill
associated with the dam footprint, spillway and any bank stream bank
stabilization. The length of stream impounded must also be indicated and
enumerated.
