VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina (see DWQ website for most current
version.).
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
None required
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For

C~ 3. It is not anticipated that the expedited process will be requested for this situation.
^ 4. If you propose to impact 150 feet or more of perennial stream or 1 acre or more
~~ , of wetland and onsite mitigation is not proposed, it is recommended that you
either locate an acceptable private bank with available credits (with
documentation to show that the bank can and shall provide the credits needed)
or obtain approval from the EEP for the entire amount of stream and or wetland
as DWQ will make the final determination as to whether or not mitigation applies.
A complete Express application is not considered received unless an EEP
approval letter is attached if mitigation is requested through EEP. Please note
that the USACE may have different mitigation requirements and thresholds.
~~ . ^ 5. State whether your project will require a CAMA Minor, Major or General Permit
and give the status of the permit.

SECTION III -PROJECT INFORMATION
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
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. Please indicate the
quadrangle name. You can go to the USGS web site (http://mac.usgs.gov/maplists/) to
verify the most recent version.
[~ The most recent version of the 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 cleanly 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. Please indicate the page or map number
from which the copy of the map was made. Copies of the current soil survey and/or soil
survey map sheets can be obtained from the local NRCS County Office
(http://www.nc.nres.usda.gov/). 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 and scale. Please include
applicable road names or State Road numbers.
C~ 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 must be scaled and
include all jurisdictional and non jurisdictional wetland, stream, water features,
State regulated buffers, topographic contours with elevations, approximate extent
and nature of forest, field, landscaping, or other cover. Any existing structures and
impervious area must be shown. Existing utility lines and easements must be
shown. Existing roads, culverts, and other pertinent features must be shown. North
arrow and the scale must be shown. Please note that the impact boundaries on the
maps should correspond to the flagged impact boundaries in the field.
~ Proposed conditions -These sheets must be scaled and show all existing
jurisdictional and non-jurisdictional wetland, stream, water features, and State
regulated buffers (delineated into Zone 1 and Zone 2) must be underlain on the site
plan(s). The plans must show all built-out structures and impervious cover. The
plans must include the final grading contours with elevations. The plans must
indicate all utilities and easements. It is likely that several versions of the final built-
outsite plans will be necessary.
E~ Drainage Plans -Final drainage plans must be included. The plans should include
the locations and pertinent elevations and sizes of the collection system and
drainage ways. All inlets and outlets must also be shown with pertinent elevations.
Scaled stormwater BMPs must also be indicated as required by DWQ rules and
policies. In certain cases, final stormwater management plans must also be
provided, but that will be addressed later in this document.
C~ Plats -The plans must show the location and layout of all sub-divided parcels with
lot identifications. Platted parcels must be developable without further impacts to
jurisdictional and non-jurisdictional wetlands, streams, water features, and State
regulated buffers.
C~ 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. All 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.

Wetland Impacts (on the site plan):
~ Precise grading and final elevation contours must be provided. Existing vegetation and
any clearing must be specified.
All subsurface utility lines must indicate the location of anti-seep collars. Construction
detail for anti-seep collars must be provided. ~,1~~ C~1-
^ ~~~ Roadway or other crossings of riparian wetlands may require floodway culverts to
^ When surface drainage features or groundwater recharge areas that feed or would
reasonably feed wetlands that are not to be filled are made impervious, it may be
necessary to direct some stormwater runoff to those areas in order to maintain hydrology.
You must identify these areas and address them. Supporting explanations and discharge
information must be provided to show that the wetland would not be eroded or receive
too much or too little hydrology. In many cases this could help satisfy part of a
stormwater management plan.
^ Flooding
^ Draining
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.
Culverting: N~d.
^ The inlet and the outlet of the culvert should be aligned with the stream as much as
possible. Inlet and outlet elevations and streambed elevations should be indicated.
^ Any widening of the stream must be shown with elevations.
^ The extent of and plan details for all dissipation or grade control devices should be shown
with pertinent elevations.
^ For shorter culvert sections, such as for road crossings, a longitudinal cross section that
shows the stream bed invert at the inlet and outlet, the existing stream bank elevations
and the invert of the inlet and outlet of the pipe(s) must be provided.
^ For shorter culvert sections, such as for road crossings, a vertical cross section must be
provided that shows the stream cross section at the inlet and outlet overlain with the
culvert and fill cross section.
^ 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.
^ For bottomless culverts or other spans, a plan view must be provided that shows the
location of the spans and the stream banks.
^ For longer culverts or culverts that will pass beneath substantial impervious cover, it will
be necessary to provide adequate plan detail to show that discharge velocity/energy will
be adequately dissipated.
maintain existing hydrological conditions.

^ >J~a Cross section details must be provided showing the provisions for aquatic life passage.
Aquatic life passage through culverts is typically achieved by placing the invert of the
culvert below the existing bed of the stream per the USACE or North Carolina Wildlife
Resource Commission guidelines. Other methods such as baffles may also be used.
Please be aware that such placement may require the use of grade/velocity control
measures up or down stream of culverts on steeper streams to prevent head-cuts or
streambed erosion. The culvert placement relative to the streambed can be indicated on
the longitudinal profile. Grade and velocity control measures must be indicated on the
plan view and typical designs should be provided.
^,J~r Multiple culverts, wide 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.
^ ~~Ar 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.
Stream Relocations: ~.1(L~
^ Stream relocations must be conducted as specified in General Certification numbers
3402 and 3404 (available on the Wetlands Unit web site). Stream relocation plans must
include:
^ Morphological measurements (see Appendix B of the Internal Technical Guide for Stream
Work in North Carolina available on the Wetlands Unit web site) -not all of the
measurements are applicable in every instance.
^ Typical stream cross sections - Typically, a riffle cross section and a pool cross section
that includes the entire flood prone area. The bankfull and flood prone area elevations
should be indicated. Similarly, a riffle cross section of the reference stream(s) should be
provided.
^ Plan view -Provide scaled plans that show the location of the proposed (preferably with
stationing) and the existing stream. In most instances, the bankfull contours and flood
prone area contours, in stream structures, bank revetments/stabilization, channel plugs,
planting plan, vegetation conditions, stormwater outlets, grade controls, bridges, culverts,
sewer lines, roads, fencing, and easement lines should also be provided.
^ Longitudinal Stream Profile - A scaled profile that indicates the thalweg, bankfull, and top
of bank elevations should be provided for the design and reference streams. In many
cases, it will also be necessary to show the existing land elevations for the design
stream.
^ Planting Plan - A planting and/or vegetation management plan should also be provided
that makes use of appropriate native vegetation. The plan should indicate the extent,
density, and species of plants to be provided.
^ In-stream structure, bank revetment/stabilization, and stormwater outlet typicals -
Detailed, typical plans should be provided for all in stream structures, bank revetments or
stabilization, and stormwater outlets. The typicals should include materials and
specifications as well as relative lengths, positions, and angles.
^ Sediment transport analysis - A sediment transport analysis should be provided based
on the current, relevant, accepted practices. The sediment transport analysis should be
relevant to the streambed load type and should predict bed load transport equilibrium.

^ Permanent conservation easement or similar means of protection must also be provided.
Other Information:
1. The project should always be referred to by this name in all correspondence as well
as the DWQ # once it is provided.
~b.2. This only applies to DOT projects, which are not expected to utilize the Express
Review Program.
~' 3. This should be the size of the project as identified by the USACE for 404 Permits or
by the Division of Water Quality for Buffer Approvals and Isolated Wetland Permits.
e~ 4. Please provide the name (as depicted on the USGS topographic map and DWQ
Stream Classification Lists) of the nearest water body(ies) to which your project is a
tributary to (e.g. "Neuse River (Falls Lake below normal pool elevation)"). (Do not
simple state "stream", "river", "ocean", "sound" or "lake".) Please provide the "stream
index number" of the named water body or water body section (e.g. "27-(1)"). Also,
please provide the full water quality classification (e.g. "WS-IV NSW CA") of the water
body. This information can be obtained from the DWQ web site
http://h2o.enr.state.nc. us/bims/Reports/reportsWB.html.
Ca/ 5. Please state which river basin and sub-basin that your project is in (e.g. "Neuse River
Basin, NEU01"). This information can be obtained from the DWQ web site
http://h2o.enr.state.nc. us/bims/Reports/reportsWB. html.
~~ 6. Conditions should also be indicated on the existing site plan where applicable.
Photos (including aerial photos) can be helpful in describing the existing conditions.
Cam' 7. You must provide an attachment that explicitly describes what the proposed project
will entail from the planning stage to final construction.
~' 8. This can be a simple explanation, but it is critically important because the purpose
dictates how the no practical alternatives are reviewed.
SECTION IV -PRIOR PROJECT HISTORY
^ -~ ~Q~ Please include copies of all 401 Water Quality Certifications, Isolated Wetland
Permits, Buffer Approvals, USACE Permits, CAMA Permits for the site as well as a
copy of the final approved, site plan.
SECTION V -FUTURE PROJECT PLANS
!r, For projects utilizing the express review process, all impacts both present and
potential future must be indicated. For instance, the location or configuration of
platted lots sometimes suggests that future impacts will be necessary to build,
access, or otherwise develop such lots. Failure to account for such potential impacts
could delay or disqualify a project from the rapid review process. If you believe that
the lot can be developed without impacts, but you anticipate that your assertion may
be questioned, it is recommended that you provide a potential building foot print
and/or grading plan to show that future impacts could be avoided.
SECTION VI -PROPOSED IMPACTS TO WATER OF THE US
C~ 1. It is recommended that the individual impacts be described if there are special things
to note about the impacts. Typically the most important thing is to have detailed
accurate site plans as described above. Please make sure they are clearly labeled.
Please include all proposed temporary impacts.

7
Also, a current, signed delineation map from the USACE should be provided (if
available) and a map locating the stream origins signed by the appropriate DWQ
Staff must be provided if applicable.
2. Each impact to a wetland must be clearly labeled and identified on the site plan. The
type of impact must be clearly stated. If the impact is temporary, a specific plan must
be described or shown as to how the wetland will be restored. Keep in mind that the
USACE delineates some features as wetlands that DWQ calls streams. Please list
any impacts in this table that DWQ would identify as a stream. If there is any doubt,
it is recommended that the impacts be listed as streams. Please follow current DWQ
policy with respect to whether a stream is perennial or not. It is recommended that
you assume that a stream is perennial (unless you are positive that it is not) so if
mitigation is required then the appropriate amount of mitigation would be anticipated
or requested from the EEP or private bank. If the EEP or private bank has pre-
approved too short of an amount of stream or if inadequate mitigation is proposed,
then that situation will result in delays.
~ 3. Sometimes it is difficult to determine whether a feature is a modified natural channel
or a ditch, especially in the eastern part of the State. Soils, drainage features,
topography, macroinvertebrates, and similar factors, all are important for making that
determination.
^ ~~ 4. Other items to address not specifically requested in the application include
downstream sediment starvation, thermal pollution, low flow releases from dams, and
aquatic life passage. Other important considerations are buffer reestablishment or
mitigation around ponds on buffered streams. The site plan should include the
precise elevation contour of the normal pool as well as the dam footprint. Mitigation
is required for wetland flooding of an acre or greater and for stream fill (if over the
150 foot threshold) under the dam footprint and any outlet stabilization.
SECTION VII -AVOIDANCE AND MINIMIZATION
Avoidance and minimization are critical aspects of an application particularly if you desire the application
to be processed expeditiously. The following is a checklist of avoidance and minimization questions that
DWQ Staff often look for in applications.
r~0 • ^ Are there any stream crossings at angles less than 75° or greater than 105°?
~ ^ Are there any stream crossings that cross two streams above or at the confluence of those
streams?
~,o , ^ Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road
crossing near the edges of the property?
,J~ ^ Can the stream be relocated as a natural channel design as opposed to culverted or
otherwise filled?
ap , ^ Is any single stream crossed more than once?
~~4 ^ Can property access routes be moved or reduced to avoid stream, wetland, water, and
buffer impacts?
yEs • ~~`"~~' Can a building, parking lot, etc. be realigned to avoid impacts?
yes . ~~ ~ Can the site layout be reconfigured to avoid impacts?
yE5 t~ ~ Can headwalls or steeper side slopes be used to avoid/minimize impacts?

q~,~, • s
~VN
.~, C~ Can a retaining wall be used to avoid/minimize impacts?
~I~p. ^ Can cul de sacs be used in place of a crossing?
~~a ^ Can lots be reshaped or have shared driveways to avoid impacts?
If based solely on the practicable physical possibility, the answer is "yes" to any of the above questions
then you must have to provide substantial and convincing justification as to why the impacts are
necessary. If the impacts are required by a local government or other agency, the claim must be
supported with appropriate written documentation from the local government or other agency. Most
projects typically involve the need to justify avoidance and minimization. If this information is not readily
available, then the express review process may not be the appropriate venue to use. Providing
alternative plans (such as plans that avoid the impact, minimize the impact and the preferred plan, similar
to those used in environmental assessments) and explanations as to why the preferred plan is needed
and why the alternative plans wonff't work are many times helpful in the no practical alternatives review.
SECTION VIII -MITIGATION N'A
Mitigation for the Express Review Program, final mitigation plans must be presented up front. The final
plans (except for plans that propose payment into the Ecosystem Enhancement Program (EEP), Riparian
Buffer Restoration Fund, private mitigation banks, or similar banking instruments) must contain detailed
plans, specifications, calculations and other supporting data that show that the appropriate mitigation will
be achieved at the ratios required. The design plans must be developed to at least the "90%" level.
Monitoring plans must be final and specific. Any means of permanent protection, such as a permanent
conservation easement must be provided. If you elect to use the EEP or a private mitigation bank, it is
recommended that you request the maximum possible mitigation amount that DWQ may require so that
you will not have to get further approval from them on short notice. The EEP and private banks are not
part of the expedited review process and cannot be expected to meet any such deadlines. There will be
no conditional expedited approvals that require final plans at a later date. It is not recommended that
innovative mitigation techniques or greater than 10% preservation be requested as part of an expedited
process.
SECTION IX ~.1~~
If your project requires the preparation of an environmental document under NEPA or SEPA and an
approval letter has not been issued by the State Clearinghouse, then you cannot apply under the
expedited review process. It is your responsibility to find out if such documentation is required.
SECTION X
There are many aspects of the Buffer Rules that must be addressed in every application, if applicable.
The first and most important thing to keep in mind is that allowable activities that require written Approval
from DWQ triggers a review of the entire project for compliance with the Buffer Rules.
Diffuse Flow 8~ stormwater Management:
~ The most common issues that arise involve the requirement for diffuse flow of stormwater
through riparian buffers. Basically one of three things must be indicated in regards to all
"new' stormwater that is collected and subsequently discharged. First, provisions for
diffuse flow through the protected buffer must be made. This usually involves the use of
level spreading devices designed to the latest DWQ guidance on level spreader design,
which is available on our web site. Please keep in mind that it does not matter how far a
discharge point is from a buffer. The stormwater must be flowing in a diffuse manner at
whatever point it eventually reaches the buffer. If the stormwater will not be flowing in a
diffuse manner through the protected buffer at the point it reaches the buffer, then one of
the following options may be allowed:
You may provide a nitrogen removing measure such as a forested filter strip,
grassed Swale, stormwater wetland, etc. The measure employed should be

designed according to the NC DENR Stormwater Best Management Practices
Manual or other DWQ Guidance available at
http://h2o.enr.state.nc.us/ncwetlands/regcert.html. After the nitrogen is treated, the
stormwater can be directly conveyed through the buffer with written DWQ approval.
^ You may discharge the stormwater to an existing man-made conveyance that
currently conveys stormwater through the protected buffer (assuming the
conveyance was not constructed in violation of the Rules) as long as that
conveyance does not need to be altered to convey the flow. Please remember that
there are no other choices. The following checklist is intended to help insure that
your application will not be deemed incomplete as a result of improper stormwater
design.
Stormwater Management (for Buffer Rules compliance only -Also, see Section XI):
^ All stormwater out-falls must be clearly shown and labeled on the site plan for projects in
Buffered watersheds. List each out-fall as labeled: ~ I a.-~p ~ I - Sc~ 4~A~ SldycT CJ»Z.
^ Option 1: Level spreading devices designed to the latest DWQ Guidance, and
devices that merely control velocity but do not provide diffuse flow such as rip rap
dissipators are not proposed. List each of these out-falls as labeled on the site
plan and provide a DWQ worksheet available at
http://h2o.enr.state. nc. us/ncwetlands/regcert. html:
Option 2: Nitrogen removing measures designed to DWQ Standards are
proposed for discharges for which diffuse flow through a protected Buffer cannot be
met. List each of these out-falls as labeled on the site plan and provide a DWQ
worksheet available at http://h2o.enr.state.nc.us/ncwetlands/regcert.html
^ Option 3: The stormwater will be discharged to an existing man-made (not
including modified natural channels) conveyance that carries the stormwater
through the Buffer. The conveyance was not constructed in violation of the Buffer
Rules. List each out-fall as labeled:
^ All stormwater out-fall must meet one of the options above. (Note: if you cannot check this
box your application will likely not be accepted into the express review process.)
Site Plans:
C~ All applications on properties with DWQ protected buffers must clearly depict the buffers
and any impacts to the buffers on the site plans. The impact maps should clearly depict
both zones of the protected buffers and the proposed impact areas (provided in square
feet).
Surface Water & Buffer Delineations:
Any surface waters subject to DWQ protected buffers must be field located and accurately
depicted on the site plans and impact maps. The width, dimensions and pattern of the
surface water must be delineated. The surface water location must not be taken simply
from a USGS map, soil survey or local municipality's map. The buffers must be measured
from the surface water as required within the applicable buffer protection rule (e.g., all
buffers along streams subject to the Neuse and Tar-Pamlico Buffer Rules must be
measured from the "top-of-bank" of the stream and not the centerline of the stream). All
streams must be surveyed or located by GPS and shown precisely on the site plans.
Impact Table:

10
rY Please provide additional impact tables that clearly state the area of impact for each
corresponding impact site.
Variances: n1(A
^ Projects that require a Major and/or "General" Variance will not be eligible for the use of the
Express Review Program (with the exception of the Coastal General "Major" Variance.
Mitigation: ~t(~,•
As opposed to applications that are submitted under our regular process, final mitigation
plans must be presented up front (see requirements for Section VIII above). The mitigation
plans must comply with the applicable buffer mitigation rule.
SECTION XI - STORMWATER
Please provide the following information in regards to potential stormwater requirements:
~ The total acreage of the site. sb.D~ (acres)
~~ The total built-out impervious acreage Zq' • In (acres)
C~ The total area that will be disturbed ~6 '2S (acres)
u If the total area exceeds 20% imperviousness, the development on the site is uniform in
density, and you claim that the total impervious area is less than 30%, you must provide a
complete, detailed breakdown of the assumed built-out conditions. The breakdown must
be detailed enough to show that all potential impervious areas are accounted for.
^ If there are concentrated areas of development such as multi-family, commercial, cluster,
club houses, etc. that exceed 30% imperviousness and the total imperviousness for the site
does not exceed 30%, a stormwater management plan will likely be required for those
areas that exceed 30% imperviousness.
~~ stormwater management plans must be complete with a final design and an executed
Operation and Maintenance Agreement. There will be no conditional stormwater approvals
for the express review process that allow for approval of the final plans at a later date.
Worksheets must be provided that are available at
http://h2o. eh n r.state. nc. us/ncwetlands/m itresto. htm I.
SECTION XII -SEWAGE DISPOSAL
Response must be clear and detailed. Any disposal method that suggests further impacts
may be required other than those shown must be clearly addressed on the site plans.
SECTION XIII
^ Answering yes to either of these responses automatically precludes you from the express
review process.
SECTION XIV -SIGNATURE
C'~ The name, position and/or title of the applicant must be in type or long hand script here with
the signature. It should be the same person as described in Part II.
If you have any questions about these requirements, please email the Express Review Program at
[e-mail] and include your question and phone number and the appropriate staff will
respond as soon as possible.

General Information
The developer is proposing the construction of a commercial retail center to include a
Wal-Mart Store, small shop buildings and 2 outparcels located within Johnston County, North
Carolina. The project site is located along NC Highway 42, about 0.5 miles east of its
intersection with Interstate 40. The project site is bound by NC Highway 42 to the north, an
existing Lowe's store to the west, vacant property to the soutf~ and Swift Creek floodplain to the
east.
The total site acreage for this project is 56.06 acres. This project area encompasses 3
existing parcels: 1) PIN 163700-26-0654, 2} PIN 163700-36-0944 and 3) PIN 163700-27-8890.
The existing parcels consist of a combination of forest/woods and open/meadow. Present land
use is vacant. There are 2 ditches that run on the project site. From the existing Lowe's site,
the Lowe's pond outfalls into a ditch that runs onto the project site, to the north running from
west to east along NC Highway 42. This ditch which runs through the project is not jurisdictional
and outfalls under NC Highway 42 through an existing 42" RCP culvert. The other ditch on site
is in the middle of the project which flows from west to east toward Swift Creek. See next
section for jurisdictional streams and wetlands on the project site,

Stream and Wetland Information
The entire site has been investigated for jurisdictional streams and wetlands. The stream
in the middle of the site has been determined to be a intermittent to start (2' wide and 392' long)
and then turning perennial at a certain point as determined by the wetland consultant and
verified by both the USACE and NCDENR. There has also been a wetland boundary identified
on the project which runs in close proximity to the floodplain boundary line. A notification of
jurisdictional determination has been received for both the stream and wetland area by the
USACE and verified by the NCDENR DWQ. It was determined that the Neuse River Buffers
shall apply to the delineated perennial stream on site at a point identified as "A3-B1." From this
point to downstream, the 50-foot Neuse River Buffers shall apply. The stream is 2 feet wide
from top of bank to top of bank. The 50-foot Buffers are measured from the top of bank which
has been determined to be the edge of the stream. For the purpose of delineating the 50-foot
buffers, a 4' wide top of bank to top of bank was used. It has been required by the DWQ that no
impacts shall occur within the Neuse River Buffers. It has also been required by Johnston
County (due to project being located within the Environmentally Sensitive Area) that no
development shall occur within the floodplain. These are given environmental site constraints
where no development of any kind will occur. It should be noted that there will be a 149.5'
impact to the stream on site and impacts of 0.026 acres to the wetlands on site. These impacts
are outside the site constraints area as noted above and will be permitted as part of the Express
Review Option by the DWQ for the Pre-Construction Notification Water Quality Certification
Permit. This Permit is under review by the DWQ.
Avoidance and Minimization of Delineated Streams and Wetlands
During the design development phase, the wetland assessment determined the location
of delineated stream and wetlands boundary on site. Based on these locations, the site has
been re-designed by moving the entire development to the west as far as it can go, abutting
against the existing Lowe's property (which is also the Lowe's dry detention pond under a 150'
CP&L Easement). By moving the entire site to the west, the Neuse River Buffer has been
completely avoided with the use of reinforced steepened slopes. Also, the proposed shop's
building has been reduced in size. It should be noted that other physical constraints exist on the
project site, which had to be considered and overcome in the overall design of the project.
These include the 100 elevation difference from the Lowe's to the floodplain, the existing 50'
Colonial Pipeline that runs through the center of the site cannot be disturbed and the 100-year
floodplain line which cannot be disturbed.

Impervious Area Calculations
The existing impervious area can be considered zero. The proposed construction will
consist of impervious surfaces for building areas, parking areas and access driveways. The 56-
acre site will be subdivided into five (5) separate parcels. This will be a commercial
development within the Environmentally Sensitive Area; therefore, the total maximum
impervious area limitation is 50% as required by Johnston County.
Parcel Size Impervious Area
Wal-Mart Tract 40.89 acres 17.3 acres
Shops 1 Tract 8.83 acres 2.37 acres
Shops 2 Tract 2.63 acres 1.32 acres
Outparcel No. 1 1.98 acres 1.63 acres
Outparcel No. 2 1.73 acres 1.40 acres
Total Project 56.06 acres 24.10 acres (42.99%)
The expected impervious area for the full build-out of all parcels is below the allowable
impervious area of 50%. Therefore, Land Dedication will not be required.
Stormwater Pond Design, Peak Runoff Reduction and Downstream Analysis
There are two main drainage areas on this project due to the existing 50-foot gas
easement bisecting the project site. The upper drainage area to Pond 1 or large pond has been
sized for the full build-out of the Wal-Mart and Shops 1 Tract. The lower drainage area to Pond
2 or small pond has been sized for the full build-out of the Shops 2 Tract, Main Driveway and
Outparcels No. 1 and 2. Both ponds have been designed as Constructed Stormwater Wetlands
per the NCDENR DWQ requirements. Due to steep slope constraints and limited property
constraints, no other combination of BMPs could achieve the minimum 30% Nitrogen Reduction
required by the DWQ. Therefore, the wetland ponds are proposed and will achieve 40%
Nitrogen Reduction thus achieving the minimum requirements. Per the NCDENR DWQ, no
other outfall requirements are necessary other than ponds must discharge with an energy
dissipater device directly to the wetland and not to the Neuse River Buffers. The 1-year storm
will discharge 1.11 cfs and the energy dissipater structure will eliminate flow velocity to zero.
Both ponds have been additionally sized to attenuate the peak flow runoff for the 1, 2, 10
and 25-year storm events as required by the County; therefore no additional downstream impact
analysis is required. Both ponds outfall directly to the large existing wetland and floodplain
associated with very large Swift Creek River. Swift Creek is located approximately 1,000 feet to
the east of the project site. Since the drainage area for the project will be less than 10% of the
total drainage area to Swift Creek, it will have an insignificant impact to the creek.

TN = [ 9.586 Ibs/ac/yr - 0.40 (9.586) ] = 5.752 Ibs/ac/yr
Since no other BMPs are possible to achieve further reduction of the total nitrogen load,
the offset payment fee is calculated as follows per the latest Johnston County requirements.
The payment is based on the difference of 3.6 Ibs/ac/yr - 5.752 Ibs/ac/yr, which is equal to
2.152 Ibs/ac/yr.
Nitrogen Payment = [ ($28.35/Ib)(# of Ibs/ac/yr)(# of Acres)(30 years) ]
Nitrogen Payment = [ ($28.35/Ib)(2.152 Ibs/ac/yr)(56.06 acres)(30 years) ]
Nitrogen Payment = $102,605.27

EAST PARK PLAZA
JOHNSTON COUNTY, NORTEi CAROLINA
Project Descriptiotr
Garner Development Partners, LLC is proposing the construction of a commercial retail
center located in Johnston County, North Carolina. The project site is located on an
approximately +1-56-acxe tract of land along NC Hig)lway 4? approxirtiately 0.5 miles east of
Interstate 40. Refer to the Site L,oeation Map and copy of the USGS map on the following pages.
The site is currently undeveloped. The site is bound to the west by a 180' CP&L powerlinc
easement (on the Lowe's property), to the north by NC Highway 42, to the east by the Swift
Creek floodplain, and to the south by vacant property. There is a 50' Colonial Pipeline easement
running northwest to southeast through the property. The existing ground cover in this area
consists of wooded areas and a mix of brush and open field areas.
The project will consist of the const~vction of a 203,704 SF Wal-Mart, 41,300 SF of
shops, associated drives, associated improvements to NC Highway 42, parking and loading
areas, utility mains and services, stormGVater management controls and conveyances, t~vo
outparcels, and landscaping.
This stormwater management report considers the pre-development and the post-
development conditions for the entire watershed on the project site. The stonnwater detention
facilities were sited for the post-development conditions per the North Carolina Division of
Water Quality (DWQ) and Johnston County Storrnwater regulations including the full build-out
of the Wal-Mart, Shops and two outparcels. The total disturbed area for this project will be
approximately +J- 36-acres.
Soils
According the USDA Soil Survey for Johnston County, North Carolina the existing soils
on site are Altavista tine sandy loam with slopes ranging from 0 to 2 percent, Rion sandy loam
with slopes ranging from 15 to 40 percent, W'eclowee sandy loam with slopes rangin4.; ti-om 2 to 8
percent, and Wedowee sandy loam with slopes ranging ti•om 8 to 1 S percent. The majority of the
onsite soils, the Wedowee and Rion soils, ate in Hydrologic Soil Group "Q." A small portion of
the site, mostly the wetlands area, are Altavista soils in Hydrologic Soil Group "C." Refer to the
soils map.

The proposed development's site stonnwater management plan has been designed such
that the post-development peak ninoff rates are less than the pre-development peak. nmoff rates
for the 1, ?, 10, and ?~ year storm events with the 100 year storm passing through the emergency
spillway. Rainfall data and attenuation requirements were taken from the i~iorth Carolina
Johnston County Stonnwater Ordinance. The H~'DRAFLOW method of analysis was utilized to
produce the pre- and post-development peak runoff rates. All CN values are: weighted values.
All data and computations reported in the following nan•ative and presented in the Appendices
reflect the HYDRAFLOW method of analysis. Refer to fp~~endi_r f3 for pre-c}evelopmcnt
calculations, post-development calculations, and detention pond calculations.
P~•e-DeveloPincnt Corrrlitians
Under pre-development conditions the site's runoff generally drains from west to east
towards the wetland area. An existing high point of 301.2 is located near the southwest corner of
the site. Within the proposed construction site, two watershed areas that discharge to the same
wetland have been analyzed and are described below. The majority of the site's runoff flocs
directly into the wetland along the eastern side of the site. Within the wetland the stonnwater
Flows through a shallow, flat unnamed tributary approximately 1,200 feet to the initial receiving
stream which is S~vif} Creek. Approximately 4.4 acres of of'f--site undisturbed land along the
southern property line flows onto the site.
Pre-Development Area No. I is generally defined as the area of the site that is south of
the 50' Colonial Pipeline easement. The stormwater flows generally towards the east and
northeast and drains into the existing wetland on the eastern side of the site. This area consists of
33.0 acres and is a mix of wooded area with some brush with open space with a weighted C\ of
56.
Pre-Development Area No. 2 is generally defined as the area of the site that is Hearth of

Post-Develop»rer~t Conditr'on,c
Two (2) on-sitca ccrostructed stonnwater wetland ponds have been designed to meet the
30°'o Nitrogen reduction requirements by the D~VQ. All storn~avater from the development of the
site will flow to either stonnwater wetland pond 1 or storm~~~ater wetland prmd 2. The post
development areas are comprised of the same tti~~o areas wider pre development conditions. The
outlets from both stonnwater wetland ponds will outlet into the existing wetland on the eastern
side of the property. Stormwater outflows will avoid immediate discharge to the defined Neusc
River Buffers and outfal} directly to the wetland with an energy dissipater as allowed by the
DWQ.
Post Development Area No. 1 is generally defined as the area south of the 50' Colonial
Pipeline easement. All of the post development stonnwater flows into stornlwater wetland pond
1. The stonnwater wetland pond 1 area consists of Wal-Mart's roof drainage and parking lot, the
eastern shop's roofdrainage and parking lot, and associated drives. There is also a 4.4 acre off=
site area south of the site. This area consists of approximately 33.0 acres with a weighted CN
value of 83.
Post Development Area No. 2 is generally defined as the area north of the 50' Colonial
Pipeline easement. Al] of the post development storm~~Tater flows into stormwater wetland pond
2. The stonnwater wetland pond 2 area consists of the northern shop's roof drainage and parking
lot, outlot 1, outlot 2, and associated drives. This area consists of approximately 7.7 acres with a
weighted CN value of 85.
Both stonnwater wetland ponds were designed to meet alt of North Carolina's Division
of Water Quality and Johnston County's requirements for wetland ponds and were each sized to
handle the first I" of nrnofl' from their respective drainage areas. See Appendix C for the
stormwater wetland pond calculatic7ris.
