RE: Cedar Chest Subdivision (Wake County - Neuse Basin)
Neuse Riparian Buffer Minor Variance Request
Dear Ms_ Chapman:
SE P 9 ;...
FTtPypg NR-WATER
VV
AND STo?RMVI"UEk 1?1? 1
Attached is a completed Variance Request Form for proposed Cedar Chest Subdivision in Raleigh. The
site is located in the Neuse River basin and contains an intermittent stream that is subject to the Neuse
Riparian Buffer Rules. The proposed subdivision will contain 8 lots on a 4.78 acre tract. Wake County
real estate records indicate the subject property has been in the Gaddy family since 1973. The current
development plan is proposed by the Gaddy family heirs.
The purpose of the minor variance request is to obtain your approval for the construction of a new home on
proposed lot 8 that will be similar in size and amenity as homes that will be constructed on lots 1-7.
Without a minor variance approval, City of Raleigh building setbacks in combination with Neuse Riparian
Buffer rules will allow only a 32 foot deep home on this lot. This assumes the home would be constructed
immediately adjacent to the building setback from the Toxey Drive right-of-way and immediately adjacent
to the outer edge of the Neuse Riparian Buffer. The minimum setback allows only a 20-foot separation
between the home and the right-of-way. The owners seek your permission to increase the home's distance
from the Toxey Drive right-of-way, while increasing the minimum depth of the home to 40 feet. The
engineer for the project has designed a stormwater collection and treatment system that will collect runoff
from all impervious surfaces on this lot. Design details for the stormwater collection and treatment system
are provided with the Express Review PCN application and on the plot plan included with this letter.
Upon your review of the proposed plot plan, you will see that the difficulties with development of proposed
lot 8 are not caused by any action of the owners or by the proposed development plan for this property.
Additionally, the Neuse Riparian Buffer rules were not in place when this property was purchased by the
Gaddy family in 1973, hence, they could not have foreseen the potential effects of this new rule on the
development potential of the property.
Thank you in advance for your time spent reviewing this minor variance request. Please do not hesitate to
call or e-mail me if you have any questions or concerns about this request or if you need any additional
information.
Sincerely,
Scott Mitchell, PE, LSS

Addendum to the Pre-Construction Notification and "Buffer Rules" Application Required for
Projects Submitted Under the
"Express Review Program"
North Carolina Division of Water Quality Version 5.0
October 1, 2006
Email Address: [e-mail]
Purpose: To provide a detailed explanation of the information required by the Division of Water Quality
in order to expedite the review of applications for 401 General Water Quality Certifications, Isolated
Wetland Permits, Stream and Wetland Mitigation Plans and Riparian Buffer Approvals (Please Note: do
not leave any questions unanswered or use terms such as "N/A" without an explanation).
Fees:

(exclusively or "in addition" to) $2,000.00
$1,000.00
$1,500.00
General $1,000.00
Please read the entire document before attempting to determine the proper fee. Fees are additive for
particular projects.
Things to keep in mind when filling out the application:
A specific answer must be provided for each question. For instance, if a numerical answer is requested
then a numerical answer must be provided along with the supporting information necessary for DWQ staff
to verify that the number is accurate. Likewise, if explanations are presented to justify certain responses,
the explanations must be completely supported by documentation. DWQ staff cannot assume that
unsupported or undocumented information is accurate. "N/A" is not an acceptable answer for any
question since the DWQ Staff reviewing the application must have an opportunity to determine whether or
not any requested information is pertinent.
All forms, guidance, worksheets, applications, etc. used must be the current versions as posted on our
web site at http://h2o.enr.state.nc.us/ncwetlands. The Express Review Program website can be found at
http://h2o.enr.state.nc.us/ncwetlands/express_review.htm. Please note that it will be responsibility of the
applicant or the applicant's consultant to verify that the current versions are used. The versions posted
on our web site will be considered to be the current versions.
You are a very important part of the success of this program, if you have suggestions or clarifications
please send your comments to the Wetlands/401 Unit of the DWQ (via email at
401 [e-mail]).
Filling Out the Pre-Construction Notification Application:
The Corps of Engineers (USACE)/DWQ official, joint Pre-Construction Notification (PCN) Application
must be used as a basis for the expedited review process. The completed application should be
presented first and the supporting information tabbed and collated in the same order. Using a custom
format is not recommended. The open squares 0 are checklist items. The following items correspond to
the numbering system on the Pre-Construction Notification Form (PCN):
IMPORTANT. USE CHECK BOXES TO TRACK PROJECT INFORMATION!!
SECTION I. PROCESSING
N( I& 2.The USACE determines which Nationwide, Regional, or General Permit is
required. If you have verified with the USACE which permit they intend to use for
your project or if you already have written approval from the USACE, please
indicate by adding "verified" or "verified, attached", respectively, in the blank next
to the Permit number requested.
? Attach the USACE Approval if you have it.
G? 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 II - APPLICATION INFORMATION
1. 15 NCAC 2H .502(1) reads as follows: "Who Must Sign Applications. The application
shall be considered a "valid application" only if the application bears the signature of a
responsible officer of the company, municipal official, partner or owner. This signature
certifies that the applicant has title to the property, has been authorized by the owner to

number and email address.
2. V If the application is not signed by the applicant, please attach the agent authorization
letter. The applicant must sign the agent authorization letter. The applicant's name
and position must also be spelled out as many signatures are difficult to read.
3. 1?"' Please provide all of the requested contact information including a fax number and
email address.
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:
EY 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/maplistso to
verify the most recent version.
k4( 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.
1%K 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.
V, 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-
out site plans will be necessary.
V/ 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.
X/ 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.
V 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):
V Precise grading and final elevation contours must be provided. Existing vegetation and
/ any clearing must be specified.
Y All subsurface utility lines must indicate the location of anti-seep collars. Construction
detail for anti-seep collars must be provided.
Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
CIS 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.
C/ Flooding
k 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:
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.
LO/ The extent of and plan details for all dissipation or grade control devices should be shown
with pertinent elevations.
;X 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.
Cf 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.
el For bottomless culverts or other spans, a plan view must be provided that shows the
location of the spans and the stream banks.
b' 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.
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.
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.
[/ 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:
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:
N' 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.
N 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.
tJ P 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.
N I ( FJ Planting Plan - A planting and/or vegetation management plan should 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.
2. This only applies to DOT projects, which are not expected to utilize the Express
Review Program.
C•Y 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.
5/ 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
hftp://h2o.enr.state.nc.us/bims/Reports/reportsWB.htmi.
INI' 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.
A/ 7. You must provide an attachment that explicitly describes what the proposed project
/ will entail from the planning stage to final construction.
L1 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
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
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
q/ 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
?(Rh 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.
J/1 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.
SV' 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?
Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road
crossing near the edges of the property?
Lu/ Can the stream be relocated as a natural channel design as opposed to culverted or
otherwise filled?
Is any single stream crossed more than once?
Can property access routes be moved or reduced to avoid stream, wetland, water, and
buffer impacts?
Can a building, parking lot, etc. be realigned to avoid impacts?
EW"' Can the site layout be reconfigured to avoid impacts?
Es/ Can headwalls or steeper side slopes be used to avoid/minimize impacts?
/ Can a retaining wall be used to avoid/minimize impacts?
L/ Can cul de sacs be used in place of a crossing?
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 won't work are many times helpful in the no practical alternatives review.
SECTION VIII - MITIGATION
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
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 & 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:
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
hftp://h2o.enr.state.nc.us/ncwetlands/regcert.htmi:
C1 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:/,lh2o.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:
CI 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:
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:
[,J 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
C*1 Please provide additional impact tables that clearly state the area of impact for each
corresponding impact site.
Variances:
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:
As opposed to applications that are submitted under our regular process, final mitigation
plans must be presented up front (see requirements for Section Vlll 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. J-75 (acres)
F/ The total built-out impervious acreage
?/ Z (acres) l
The total area that will be disturbed Ls Z (acres) (e54?,w`, 4ed )
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.
C 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.ehnr.state.nc.us/ncwetiands/mitresto.html.
SECTION XII - SEWAGE DISPOSAL
C? 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
h? Answering yes to either of these responses automatically precludes you from the express
review process.
SECTION XIV - SIGNATURE
!-f-1, 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.

Re: Cedar Chest Subdivision (Wake County - Neuse River Basin)
Pre-Construction Notification Application - Express Review
Dear Mr. Shern and Mrs. Gilleski:
Attached is a complete PCN application package for the proposed Cedar Chest Subdivision.
Cedar Chest is located on Toxey Road off Saint Mary's Road inside the Beltline in Wake County.
The project site is a 4.78 acre residential site located in a well developed residential
neighborhood. There is currently one house on the lot and it will be divided into 8 lots.
. The jurisdictional impact for the proposed subdivision includes one road crossing. The road
crossing is needed to gain access to the property for the proposed subdivided lots. Total impacts
for the project are 0.00975 acres of wetland for the road crossing, 107 linear feet of stream
channel, and 11,791 square feet protected buffers. There is no mitigation proposed for this
project.
Please feel free to call me if you have any questions or concerns regarding the attached PCN
application or if you need any additional information. Thank you.
Sincerely,

Robin Eddy

• VII. Impact Justification (Avoidance and Minimization)
Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts. The street is designed
according to the City of Raleigh street & subdivision design standards. The existing 24" CPM
pipe will be utilized as to avoid reposition a new pipe.
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, available at
http://h2o.enr.state.nc.us/ncwetlands/strmgide.htm].
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.

Instructions for completion of worksheet (located on page 2): Begin by detennining the most appropriate ecoregion based on
location, terrain. vegetation, stream classification, etc. Every, characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides a brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.

This channel evaluation form is intended to be used only as a guide to assist landowners and environmental professionals in
• gathering the data required by the United States Army Corps of Engineers to make a preliminary assessment of stream
quality. The total score resulting from the completion of this form is subject to USAGE approval and does not imply a
particular mitigation ratio or requirement. Form subject to change - version 06,03. To Comment, please call 919-876-8441 x 26.
