9. Describe the existing conditions on the site and general land use in the vicinity of the project
at the time of this application: The project site consists of wooded, undeveloped land. The
site is located in a fast rowing, semi-rural, residential area within the Town of Cary limits.
10. Describe the overall project in detail, including the type of equipment to be used:
The Wake County Public School System is proposing to construct Mills Park Elementary
School E-22) on a 20 acre portion of a 239 acre parent parcel. In order to access the School
the County plans to construct Mills Park Drive across an approximately 150 foot wide
wetland which includes an unnamed tributary (UT) to Panther Creek. The UT is considered
an Important Perennial Stream. A secondary Unimportant Channel that caries flow through
the wetland will also be crossed. A future Middle School and Town of Cary Public Park is
planned for the remaining_portion of the parent parcel.
Construction of Mills Park Drive will take place within a 75 foot wide right of way. The
right of way will consist of earthen fill, a three lane asphalt paved road, sidewalks, curb and
gutters, and underground utilities (water, sewer, and electric). The total impervious surface
will be 55 feet wide. An additional 10 feet of grassed fill will also be present on each side of
the proposed road.
One 12 foot wide by 7 foot tall box culvert and one 12 foot wide by 8 foot tall box
culvert, both 145 linear feet long, will be installed side by side at the important channel. The
8 foot tall culvert will be installed 1 foot below the existing_grade to allow free water
movement and aquatic life passage under the road. The 7 foot tall culvert will be installed at
grade to maintain the natural h d~gy of the system as well as prevent constriction of the
floodwav that may result in aegradation, degradation or significant chan eg s in hydrology of
the stream and/or wetland. In addition a .081 acre dissipater pad will be placed at the outfall
of the two box culverts in the bed and bank of the important channel.
One 36 inch reinforced concrete pipe measuring 142 feet in length will be installed 6 inches
below grade at the secondary/unimportant channel to maintain the natural h dig o
system as well as prevent constriction of the floodwav that may result in ag~radation,
degradation or significant chan eg s in hydrology of the stream and/or wetland.
All construction activities will be performed in accordance with Best Management
Practices and the NC Sediment and Erosion Control Planning and Design Manual. The
mechanical equipment used during the constriction of the project site will include
conventional earth moving equipment used during development such as excavators,
bulldozers, compactors, and other conventional earthwork construction equipment.
Temporary impacts will include placing approved dewatering devices. clean water dikes.
pumps, and discharge hoses within the streams and wetlands. These approved dewatering
devices will be used to temporarily divert each of the stream channels through the discharge
hose during the installation of the culverts and pipe as well as during a portion of the road
construction process. These dewatering devices will be removed and the area will be
restored to the on ig nal rg ade (where applicableLpon completion of the project. Please see
the attached site plans for additional information.
11. Explain the purpose of the proposed work: The purpose of Mills Park Drive is to ain
access to Mills Park Elementary School and future Middle School and Town of Cary Public
Park from the main thorou hfare Durham to Green Level Road, .The purpose of the school
is to help alleviate some of the overcrowding within the school system and provide the local
Page 3 of 11

residents with adequate learning facilities. According to their website, the Wake County
Public School S sty em wined more than 7 500 new students for 2006-07. Estimates show
WCPSS increasing by 40 000 students between 2005 and 2010, bringing total enrollment to
more than 160 000 students.
IV. Prior Project History
If jurisdictional determinations and/or permits have been requested and/or obtained for this
project (including all prior phases of the same subdivision) in the past, please explain. Include
the USACE Action ID Number, DWQ Project Number, application date, and date permits and
certifications were issued or withdrawn. Provide photocopies of previously issued permits,
certifications or other useful information. Describe previously approved wetland, stream and
buffer impacts, along with associated mitigation (where applicable). If this is a NCDOT project,
list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules. F&R is not aware of jurisdictional delineations and/or permits that
have been requested and/or obtained for this project in the past.
V. Future Project Plans
Are any future permit requests anticipated for this project? If so, describe the anticipated work,
and provide justification for the exclusion of this work from the current application.
F&R has been informed that future permit requests in connection with this project will be
required. One additional crossing~ust north of the current project will be permitted separately to
allow access to a planned park and future middle school. This crossing is planned for future
development is not part of the present project and is therefore not being_permitted at this time.
F&R assumes that the crossing will be permitted at the appropriate time.
VI. Proposed Impacts to Waters of the United States/Waters of the State
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.
1. Provide a written description of the proposed impacts:
The Wake County Public School System is proposing to construct an asphalt road across an
approximately 150 foot wide wetland which includes one important channel that is a UT of
Panther Creek and one unimportant channel. The crossing is part of a larger plan to construct
Mills Park Elementary School and future Middle School and Town of Cary Public Park.

Construction of the road will take place within a 75 foot wide right of way. The right of way
will consist of earthen fill, a three lane asphalt paved road, sidewalks, curb and gutters, and
underground utilities (water, sewer, and electric). The total impervious surface will be 55 feet
wide. An additional 10 feet of grassed fill will also be present on each side of the proposed
One 12 foot wide by 7 foot tall box culvert and one 12 foot wide by 8 foot tall box culvert,
both 145 linear feet long, will be installed side by side at the primary/important channel. The
8 foot tall culvert will be installed 1 foot below the existing`arade to allow free water
movement and aquatic life passage under the road. The 7 foot tall culvert will be installed at
grade to maintain the natural hydrology of the system as well as prevent constriction of the
floodwa~that mawresult in aggradation, degradation or significant Chan eg s in hydrolog~of
the stream and/or wetland. In addition a .081 acre dissipater pad will be placed at the outfall
of the two box culverts.
One 36 inch reinforced concrete pipe measuring: 142 feet in length will be installed 6 inches
below grade at the secondary/unimportant channel to maintain the natural hydrology of the
system as well as prevent constriction of the floodwa_y that may result in aggradation,
degradation or significant chan eg s in hydrology of the stream and/or wetland.
Temporary impacts will include placing approved dewatering devices, clean water dikes,
pumps, and discharge hoses with in the streams and wetlands. These approved dewatering
devices will be used to temporarily divert each of the stream channels through the discharge
hose during the installation of the culverts and pipe as well as during a portion of the road
construction process. These dewaterin~ devices will be removed and the area will be
restored to the on final rg ade (where applicable upon completion of the project. Please see
the attached site plan for additional information.

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.
Impacts have been avoided and minimized to the extent practical during_project planning and
design. In order to meet the purpose and need of this project and to access the developable
portion of this tract from the closest main thoroughfare, the wetland and streams will need to be
crossed. The crossing will be perpendicular to the streams and wetland in an area that offers the
least amount of impact while still meeting_the purRose and need of the project site.
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
Page 7 of 11

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

Yes ^ No
Is this an after-the-fact permit application? Yes ^ No
XIV. Cumulative Impacts (required by DWQ)
Will this project (based on past and reasonably anticipated future impacts) result in additional
development, which could impact nearby downstream water quality? Yes ® No ^
If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with
the most recent North Carolina Division of Water Quality policy posted on our website at
http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description:
The Wake County Public School System is proposing to cross a wetland and small stream
with an access road and utility lines as part of a larger plan to construct a new elementary
School. A future middle school and public park are also planned for the site. The proposed road
and utility lines are intended to provide access as well as safe and reliable drinkin water op wer
and sanitary sewer for use by the schools. Residential growth in the project area is already
increasing rapidly and is likely to continue with or without the construction of the school.
However, residential growth in the area may hasten as a result of the construction of the
proposed schools.
Indirect and cumulative water quality impacts may accrue from future development. It is
presumed that future development will be in accordance with the Town of Cary's Land Use Plan
and NCDENR Sediment and Erosion Control Plans. However, loss of riparian forests and
increased impervious surface area reduces rainfall infiltration, increases soil erosion, and
concentrates pollutants. Urban stormwater pollutants include motor vehicle fluids, heavy metals
pesticides, fertilizers, solvents, detergents, eroded soil, and animal waste. As a result, peak
stream flows are typically increased causing stream bank erosion channel destabilization
degradation of in-stream habitat, and increased magnitude and frequency of flooding
Conversely, the increase in impervious surface area and soil compaction that occurs with
development can reduce infiltration rates, which may in turn reduce base stream flows during dry
weather, adversely affecting aquatic habitat. Sediment, nutrients and other forms of pollution
from agricultural sources will likely decline as the area develops but urban stormwater impacts
will likel~ncrease.
XV. Other Circumstances (Optional):
It is the applicant's responsibility to submit the application sufficiently in advance of desired
construction dates to allow processing time for these permits. However, an applicant may
choose to list constraints associated with construction or sequencing that may impose limits on
work schedules (e.g., draw-down schedules for lakes, dates associated with Endangered and
Threatened Species, accessibility problems, or other issues outside of the applicant's control).
Page 10 of 11

The E22 Access Road is being_proposed to gain access to a proposed school in order kee~pace
with the rapid growth of students in Wake County, which is expected to increase by an additional
8,000 students by the start of the 2008 school year. Based on this rapid growth Wake Coun is
attempting to have this school completed bey 2008 in order to lessen the effects of expected
student population growth and to compensate for overcrowding within the existing schools. The
proposed elementary school has a capacity of 800 students and would help to reduce
overcrowding within the elementary school system if it can be completed by the proposed date.

87 Acre Revised E22 Wake County School Site
Cary, Wake County, hortk Carolina
Trlgon Project No. 042-0G-16S
Dear Mr. Howard:
Trigon F,ngineoring Consultants, Inc. (Trigon) is pleased to provide this report of our survey for wetlands
and streams at the referenced site. This report summarizes ow field methods, observations, and
conclusions.
BACKGROUND
The site is located southeast of the intersection of Green Level to Durham Road and Cary Glen
Boulevard in Wake County, North Carolina (Figure I ). Site access was provided by a dirt road entering
the property from the east near the intersection of Twyla Road and Hilliard Lane. The site consists of
approximately 87 acres of wooded. rolling land draining to the west toward an unnamed tributary to
Panther Creek and north toward Panther Creek. Figure 2 is a 1999 aerial photograph showing the recent
ccmdition of the property. The site is reportedly being evaluated as a possible futwe location for a
school. Tate property boundaries were not marked at the site at the time of our field work.
WETLANDS
'11te site was visited on September t3 and 19, 2006 for the purpose of identifying conditions supporting
wetlands. ~Che methodology used to identify areas suspected of having conditions to support wetlands
included walk-ng the suspected areas to observe existing vegetation, soil characteristics, and hydrology.
Wetlands are defined by the t.~.S. Army Corps of Engineers (USAGE) and the United States
Environmental Protection Agency as "those areas that are inundated or saturated by surface or
groundwater at a frequency and. duration sufficient to support, anal under normal circumstances, do
support a prevalence of vegetation #ypicalty adapted for life in saturated soil conditions." In order for an

area to be classified as wetlands, hydroph}tic vegetation, hydric soils, and wetlands hydrology indicators
must be present. Identification of wetlands was based on the 1987 Cotes of Engineers Wetland
Delineation Manual.
Several small areas at the site were observed to be inundated at the time of our site visit, and extensive
areas of wetlands and stream channels were observed at the western property boundary and northeastern
corner of the property (Figure 3). Wetlands were also observed within the interior of the site along an
intermittent stream channel. Hand auger soil borings were performed to observe soil and hydrology at
multiple locations at the site. Soil observed within our hand auger borings appeared to confirm the
mapped soil types. A copy from Sheet 45 of the Soil Survey of Wake County, North Carolina produced
by the USDA Soil Conservation Service is attached (Figure 4). Wetlands were marked in the field with a
combination of white and red survey tape.
STREAl4IS
liasod on our observations at the site, three first order stream channels are located within the property
limits. Une intermittent stream channel originates at a head cut on-site in the central portion of the
proporty. The sueam flows approximately 1,250 feet to the western property boundary. A second
intermitten/ stream channel drains to the west from an origin approximately 350 feet inside the property.
The third steam channel appears to be perennial and flows approximately 700 feet to the northern
property boundary'.
Surface waters at the site are within the watershed of Panther Creek. Panther Creek flows into Jordan
[.ake and the Naw River. These watersheds are within the Cape Fear River Basin. Based on the North
Carolina Administration Code (15A NCAC 2B .0300), Panther Creek and its tributaries are classified as
WS-!V waters intended for water supply purposes and are nutrient sensitive waters. The state currently
has no buffer requirements for these surface waters. Surface waters at the site would be considered
jurisdictional "Waters of the United States" regulated undar Section 404 and Section 401 of the Clean
Water Act. Section 404 is administered by the USACF. Section 401 is administered by the North
Carolina Department of Environment and Natural Resources Division of Water Quality (DWQ). These
programs regulate the discharge of drEdged or fill material into "Waters of the United States," and ensure
State Water Quality Standards are maintained. Any impacts to the streams may require permitting.
Impacts may include such activities as placing fill within the stream banks. temporary or permanent
stream crossings, or re-routing or piping the stream channels.
The Town of Cary. North Carolina Ladd Development Ordinance (LDO) Section 7.3.2(A) roquires the
following stream buffers:
I. All perennial. and intermittent streams, including lakes, ponds, and other bodies of water as
indicated on the most recent. version of the 1:20,000 scale (7.5 minutes) quadrangle topographic
maps prepared by the United States Geological Survey (USGS) shall have a 100-foot-wide
riparian buffer directly adjacent to such surface waters, excluding wetlands.
2. All other surface waters as indicated by the most recent version of the Soil Sun'ey of
Wake or Chatham County, \orth Carolina. shall have a 50-foot-wide riparian buffer
adjacent w such waters.

Based an review of the Green Level USGS Quadrangle (Figure 5), Panther Creek and the unnamed
tributary to Panther Crcek west of the site would be subject to the 100 foot buffer, The 100 foot buffer
would likely extend onto the property from portions of the stream located along the ~vcstern boundary of
the site, U addition. a 100 foot buf'f'er may extend onto the northeast corner of the property adjacent to
Panther Creek (Figure 3).
Based on review of Sheet 45 of the Soil Survey of Wakc County (Figure 4), North Carolina, portions of
four streams are mapped at the property. However, our field reconnaissance indicates that portions of
three of the streams mapped in the soil survey are present at the site. The site was visited with Mr. Mats
Flynn of the Town of Cary Engineering Department on October 12, 2006 to coafirm the results of our
field roconnaissance since it conflicted with the sail survey map. Based an the Town of Cary LDO, a 50
foot buffer would extend from the top of the stream banks (both sides of stream) for each of the streams
within the property boundaries shown on Figure 3.

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: 401 [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:
401 Water Quality Certifications:
Riparian Buffer Authorization:
Riparian Buffer Minor Variance:
Coastal General "Major Variance°
Isolated Wetland Permit:
Major (>/= 150' stream or >/= 1 acre wetlands) $2,000.00
Minor (< 150' stream or < 1 acre wetlands) $1,000.00
(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 (USAGE)/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 (~ 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 1NFORMAT/ON!I

SECTION 1. PROCESSING
~ 1 8~ 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.
DS 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.
N/A ^ 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. 75 NCAC 2H .502(f) 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
apply for certification or is a public entity and has the power of eminent domain. Said
official in signing the application shall also certify that all information contained therein
or in support thereof is true and correct to the best of his/her knowledge."
~ Please indicate how the applicant meets the above definition and provide
supporting documentation.
~ Please provide all of the requested contact information including a fax
number and email address.
2. L~ 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. ~ 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:
~ 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/maplistsn 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.govn. GIS soil layers are not acceptable.
l~ 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.
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.
~ 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.
~ 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.
L~ 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.

4
Wetland Impacts (on the site plan):
~ Precise grading and final elevation contours must be provided. Existing vegetation and
any clearing must be specified.
N/A ^ 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.
L~ 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:
~ 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.
N/A^ 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.
L~ 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.
N/A^ 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.
N/A^ 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.

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.
1/ 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.
N/A^ 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: N/A
^ 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.

6
^ Permanent conservation easement or similar means of protection must also be provided.
Other Information:
1/ 1. The project should always be referred to by this name in all correspondence as well
as the DWQ # once it is provided.
N/A^ 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.
~ 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.
~ 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 DWO 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.
~ 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
N/A^ 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 tot 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
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 DWO
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
DWO Staff often look for in applications.
C10 ^ Are there any stream crossings at angles less than 75° or greater than 105°?
n0 ^ Are there any stream crossings that cross two streams above or at the confluence of those
streams?
n0^ Are there any stream, wetland, water, and/or buffer impacts other than perpendicular road
crossing near the edges of the property?
no^ Can the stream be relocated as a natural channel design as opposed to culverted or
otherwise filled?
n0 ^ Is any single stream crossed more than once?
n0^ Can property access routes be moved or reduced to avoid stream, wetland, water, and
buffer impacts?
n0^ Can a building, parking lot, etc. be realigned to avoid impacts?
no^ Can the site layout be reconfigured to avoid impacts?
no^ Can headwalls or steeper side slopes be used to avoid/minimize impacts?

8
no^ Can a retaining wall be used to avoid/minimize impacts?
N/A^ Can cul de sacs be used in place of a crossing?
N/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 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 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.
N/A^ 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):
N/A^ 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
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:
N/A^ 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 8~ Buffer Delineations:
N/A^ 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
N/A^ Please provide additional impact tables that clearly state the area of impact for each
corresponding impact site.
Variances:
N/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:
N/A^ 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:
C~ The total acreage of the site. 15.84 (acres)
L~ The total built-out impervious acreage 4.33 (acres)
+~ The total area that will be disturbed 8.26 (acres)
~ 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.
N/A^ 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.ehnr.state. nc. us/ncwetlands/mitresto. html.
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
L~ Answering yes to either of these responses automatically precludes you from the express
review process.
SECTION XIV -SIGNATURE
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
401 [e-mail] and include your question and phone number and the appropriate staff will
respond as soon as possible.

Re: Written Verification for use of NWP No. 39
Mills Park Drive (E-22 Elementary School Access Road)
Cary, North Carolina
F&R Project No. G66-273GE
Dear Ms. Cynthia Van Der Wiele:
Froehling & Robertson, Inc., (F&R) has been contracted by Wake County Public School System
to provide wetland and stream consulting services for the proposed Mills Park Drive (E-22
Access Road) project site. F&R is submitting this letter as written verification that the US Army
Corps of Engineers (USAGE) will accept Nation Wide Permit (NWP) No. 39 for this project in
response to your request for more information.
The project site is located in Cary, Wake County approximately 4,000 feet south of the
intersection of Green Level Road and Durham Road in Cary, North Carolina. The project site
will impact approximately 0.491 acres of wetlands and an unnamed tributary of Panther Creek,
which is located in the Cape Fear River Basin, Cataloging Unit Number 03030002.
The initial Pre-Construction Notification (PCN) listed approximately 425 linear feet (LF) of
stream impacts for one primary channel and one secondary channel of a braded stream network.
The stream impact threshold for NWP No. 39 is 300 LF. On Tuesday, March 27, 2007 F&R met
with James Shern, field representative for the USAGE, at the project site. Mr. Shern confirmed
that the secondary channel is an un-import channel thereby reducing stream impacts to 259 LF of
important channel. Mr. Shern gave verbal confirmation that the USAGE would accept NWP No.
39 for this project.

FINDING OF NO SIGNIFICANT IMPACT AND ENVIRONMENTAL ASSESSMENT
WAKE COUNTY -MILLS PARK ELEMENTARY
Pursuant to the requirements of the North Carolina Environmental Policy Act (N.C.G.S. § 113A-1,
et seq.), an environmental assessment (EA) has been prepared by Wake County for the construction
of Mills Park Elementary School and a public park in Cary. The County is proposing to build a 3-
story, 101,000 square foot building and associated roads, landscaping, parking, and athletic fields,
which will impact approximately 20 acres of a 239 acre site. The remaining 186 acres will be
utilized for the park.
Impacts to topography and floodplains are not expected to be significant. Grading the site and the
construction of temporary access roads will affect site soils. DENR-approved sediment and erosion
control plans will be obtain prior to construction to limit excessive silt and sediment loadings to
streams. Also, a stormwater plan for the site has been submitted to DWQ to prevent excessive
runoff from the site; stormwater will not be discharge directly into surface waters. Wetland and
stream impacts have been reduced by project planning and design; one wetland, one stream, and one
unimportant channel will be crossed. Crossings will incorporate culverts to maintain the natural
hydrology of the stream and prevent constriction of the floodway. 100-foot wide riparian buffers
will be maintained along streams. All federal and state permits will be obtained prior to
construction. Mitigation for jurisdictional impacts will be through payments to the Ecosystem
Enhancement Program. Emissions from construction vehicles may result in minor localized air
quality impacts. Frequent wetting of disturbed soils and prompt soil stabilization should minimize
air .quality impacts. Open burning of construction debris is not proposed. Nuisance noise
associated with project construction will be limited to daylight hours on normal workweek days.
Approximately 9 acres will be cleared for construction, with efforts made to preserve older and
larger trees. Also, grubbing will not be allowed under the tree canopy. While wildlife may be
displaced during construction, it is anticipated that species will return once noise associated with
construction is complete.
The proposed project will not impact prime or unique agricultural lands; any public, scenic,
recreational, or state park areas; or areas of archaeological or historical value.
This project will not result in secondary and cumulative impacts.
Based on the findings of the EA, the impact avoidance/mitigation measures contained therein, and
reviewed by governmental agencies, the Division of Water Quality has concluded that the proposed
project will not result in significant impacts to the environment. This EA and Finding of No
Significant Impact (FONSI) are prerequisites for the issuance of Division of Water Quality permits
necessary for the project's construction. An Environmental Impact Statement will not be prepared
for this project. This FONSI completes the environmental review record, which is available for
inspection at the State Clearinghouse.

This letter replaces one previously issued dated April 4, 2{107. The purpose of this letter is to notify you that the North
Carolina Ecosystem Enhancement Program (NCEEP) is willing to accept payment for impacts associated with the above
referenced project. Please note that this decision does not assure that the payment will be approved by the permit issuing
agencies as mitigation for project impacts. It is the responsibility of the applicant to contact these agencies to determine if
payment to the NCEEP will be approved.
This acceptance is valid for six months from the date of this letter and is not transferable. If we have not received a copy of
the issued 404 Permit/401 Certi~catiodCAMA permit within this time frame, this acceptance will expire. It is the
applicant's responsibility to send copies of the pernuts to NCEEP. Once NCEEP receives a copy of the permit(s) an invoice
will be issued based on the required mitigation in that permit and payment must be made prior to conducting the authorizc;d
work. The amount of the In Lieu Fee to be paid to NCEEP by an applicant is calculated based upon the Fee Schedule and
policies listed at www.nceep.net.
Based on the information supplied by you the impacts that may require compensatory mitigation are summarized in the
following table.
Cape Feaz

Upon receipt of payment, EEP will take responsibility for providing the compensatory mitigation. )f the regulatory agencies
require mitigation credits greater than indicated above, and the applicant wants NCEEP to be responsible for the additional
mitigation, the applicant will need to submit a mitigation. request to NCEEP for approval prior to permit issuance. The
mitigation will be performed in accordance with the Memorandum of Understanding between the N. C. Department of
Environment and Natural Resources and the U. S. Army Corps of Engineers dated November 4, 1998.
