Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River
Buffer Protection Rules (15A NCAC 2B .0233) with Additional Conditions
Dear Mr. Patsey:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 149 linear feet of streams and 19,561 square feet (ft) of protected riparian
buffers for the purpose of constructing a residential subdivision at the subject property, as described
within your application dated December 13, 2005 and received by the N.C. Division of Water Quality
(DWQ) on December 13, 2005. After reviewing your application, we have decided that the impacts are
covered by General Water Quality Certification Number(s) 3402 (GC3402). The Certification(s) allows
you to use Nationwide Permit(s) 39 when issued by the US Army Corps of Engineers (USACE). This
letter shall also act as your approved Authorization Certificate for impacts to the protected riparian
buffers per 15A NCAC 213 .0233. In addition, you should obtain or otherwise comply with any other
required federal, state or local permits before you go ahead with your project including (but not limited
to) Erosion and Sediment Control, and Non-discharge regulations. Also, this approval to proceed with
your proposed impacts or to conduct impacts to waters as depicted in your application shall expire
upon expiration of the 404 or CAMA Permit.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If the property is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A
NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached
certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The following impacts are hereby approved as long as all of the other specific and general
conditions of this Certification (or Isolated Wetland Permit) are met. No other impacts are
approved including incidental impacts:

2. Erosion & Sediment Control Practices
Erosion and sediment control practices must be in full compliance with all specifications
governing the proper design, installation and operation and maintenance of such Best
Management Practices in order to protect surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Sediment and Erosion Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control
measures must be such that they equal, or exceed, the requirements specified in the most
recent version of the North Carolina Sediment and Erosion Control Manual. The devices
shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects,
including contractor-owned or leased borrow pits associated with the project.
3. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond
the footprint of the impacts depicted in the Pre-Construction Notification. All construction
activities, including the design, installation, operation, and maintenance of sediment and erosion
control Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
4. Diffuse Flow
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non-erosive velocities through the protected stream buffers such that it will not re-concentrate
before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not
possible, it may be necessary to provide stormwater facilities that are considered to remove
nitrogen. This may require additional approval from this Office.
5. Protective Fencing
The outside buffer, wetland or water boundary and along the construction corridor within these
boundaries approved under this authorization shall be clearly marked with orange warning
fencing (or similar high visibility material) for the areas that have been approved to infringe
within the buffer, wetland or water prior to any land disturbing activities to ensure compliance
with 15A NCAC 2B 33 and GC 3402.
6. Construction Stormwater Permit NCG010000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land
Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an
NPDES General stormwater permit (NCGO 10000) administered by DWQ is automatically issued
to the project. This General Permit allows stormwater to be discharged during land disturbing
construction activities as stipulated by conditions in the permit. If your project is covered by this
John Wieland Homes
Page 3 of 4
January 31, 2006
permit [applicable to construction projects that disturb one (1) or more acres], full compliance
with permit conditions including the sedimentation control plan, self-monitoring, record keeping
and reporting requirements are required. A copy of this permit and monitoring report forms may
be found at http://h2o.enr.state.nc.uslsulForms Documents.htm.
7. Deed Notifications
Deed notifications or similar mechanisms shall be placed on all retained jurisdictional wetlands,
waters and protective buffers in order to assure compliance for future wetland, water and buffer
impact. These mechanisms shall be put in place prior to impacting any wetlands, waters and/or
buffers approved for impact under this Certification Approval and Authorization Certificate. A
sample deed notification can be downloaded from the 401/Wetlands Unit web site at
http://h2o.enr.state.nc.us/ncwetlands. The text of the sample deed notification may be modified
as appropriate to suit to this project.
8. Culvert Installation
Culverts required for this project shall be installed in such a manner that the original stream profiles
are not altered. Existing stream dimensions (including the cross section dimensions, pattern, and
longitudinal profile) must be maintained above and below locations of each culvert. Culverts shall
be designed and installed to allow for aquatic life movement as well as to prevent head cutting of
the streams. If any of the existing pipes are or become perched, the appropriate stream grade shall
be re-established or, if the pipes installed in a perched manner, the pipes shall be removed and re-
installed correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the
stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below
the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches,
and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow
low flow passage of water and aquatic life. Design and placement of culverts and other structures
including temporary erosion control measures shall not be conducted in a manner that may result in
dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream of the
above structures. The applicant is required to provide evidence that the equilibrium shall be
maintained if requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques
must be used where practicable instead of rip rap or other bank hardening methods. If rip-rap is
necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of
Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed
to adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicant shall complete and return the enclosed "Certificate of
Completion" form to notify NCDWQ when all work included in the §401 Certification has been
completed. The responsible party shall complete the attached form and return it to the
401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please
John Wieland Homes
Page 4 of 4
January 31, 2006
send photographs upstream and downstream of each culvert site to document correct installation
along with the Certificate of Completion form.
Installation of culverts in wetlands must ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions.
9. No Sediment & Erosion Control Measures w/n Wetlands or Waters
Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters
is unavoidable, they shall be removed and the natural grade restored within six months of the date
that the Division of Land Resources has released the project.
10. Certificate of Completion
Upon completion of all work approved within the 401 Water Quality Certification or applicable
Buffer Rules, and any subsequent modifications, the applicant is required to return the attached
certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality,
1650 Mail Service Center, Raleigh, NC, 27699-1650.
Violations of any condition herein set forth may result in revocation of this Certification and may result in
criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon
expiration of the 404 or CAMA Permit.
If you do not accept any of the conditions of this Certification (associated with the approved wetland or
stream impacts), you may ask for an adjudicatory hearing. You must act within 60 days of the date that
you receive this letter. To ask for a hearing, send a written petition, which conforms to Chapter 150B of
the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a
hearing.
Any disputes over determinations regarding this Authorization Certificate (associated with the approved
buffer impacts) shall be referred in writing to the Director for a decision. The Director's decision is
subject to review as provided in Articles 3 and 4 of G.S. 150B.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act and the Neuse riparian buffer protection rule as described within 15A NCAC 2B .0233. If you have

OAK{'E(":ie,6tcfia?Gtti
Dear Mr. Matthews and Ms. Karoly,
On behalf of John Wieland Homes, we are requesting authorization from the USACE to use
NWP 39 for the installation of a roadway. We are also requesting 4o1-certification from the
NC-DWQ and buffer compliance for road construction, utility line installation and a greenway
trail.
The site is located in Cary, on the west side of Harrison Avenue (SR 1652), just south of the
intersection of Homestead Drive and Harrison Avenue and is approximately 20.5 acres in
size. The project is located in the Neuse Basin and contains un-named tributaries to
Crabtree Creek. A wetland delineation was conducted by Withers & Ravenel in August of
2005. Data forms are included with the attachments in support of our delineation. Site
meetings were conducted with the NC-DWQ on August 5, 2005 (DWQ # 05-13o9). The
Hydrologic Unit Code for this basin is 030202o1. The Water Quality classification is B-NSW,
stream index 27-33-(3.5)•
The current request is for149 linear feet of unimportant stream impact and 0.45 acres of
riparian buffer impact (see the attached maps and PCN for a detailed accounting of the
buffer impacts). Because the impacts are less than 150 linear feet and because the buffer
impacts are less than 0.33 acres at the road crossing, we do not believe that mitigation will
be required. If mitigation is required, the applicant proposes payment to the NC-EEP. Please
note that the applicant proposes parallel impacts to Zone 2 of the riparian buffer for utility
line installation and for a second level spreader. The utility line impacts are necessary due
to topographic constraints and additional level spreaders are needed to provide diffuse flow
along steep slopes. The level spreaders have been designed as per the DWQ guidelines and
we have included the DWQ level spreader worksheets.

local stormwater requirement, etc.): NA
Current land use in the vicinity of the pond: NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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 stream bisects the property
and the impacts could not be avoided in order to access the entire parcel However, impacts to
the stream channel were minimized through the use of headwalls The parallel impacts to the
buffer are needed for the utility line installation due to the topography and the depth of the sewer
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
Page 5 of 9
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
fof 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/newetlands/strmgide.html.
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.
Because the impacts are to an unimportant channel and because the impacts are less than
150 linear feet we do not believe that mitigation should be required. If mitigation is
required the applicant proposes payment to the NC-EEP.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http•//h2o.enr.state.nc.us/wry/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): NA
Amount of buffer mitigation requested (square feet): NA
Amount of Riparian wetland mitigation requested (acres): NA
Amount of Non-riparian wetland mitigation requested (acres): NA
Amount of Coastal wetland mitigation requested (acres): NA
IX. Environmental Documentation (required by DWQ)
1. Does the project involve an expenditure of public (federal/state/local) funds or the use of
public (federal/state) land? Yes ? No
2. If yes, does the project require preparation of an environmental document pursuant to the
requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)?
Note: If you are not;, sure whether a NEPA/SEPA document is required, call the SEPA
coordinator at [phone] to review current thresholds for environmental documentation.
Page 6 of 9
Yes -[:1 No n
3. If yes, has the document review been finalized by the State Clearinghouse? If so, please
attach a copy of the NEPA or SEPA final approval letter. Yes ? No ?
X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.
1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Neuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC
2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please
identify )? Yes ® No ?
2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers.
If buffer mitigation is required calculate the required amount of mitigation by applying the
buffer multipliers.

additional 20 feet from the edge of Zone 1.
3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e.,
Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B.0242 or.0244, or.0260. NA
i
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater
controls proposed in order to protect surface waters and wetlands downstream from the property. If
percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed
impervious level. The site does not currently contain impervious surface following construction the site
will contain approximately 25% impervious A detailed accounting of the impervious surface is included
with the attachments Because the impervious is less than 30% we do not believe that a stormwater
management plan is required by the NC-DWQ In order to protect water quality downstream, the
applicant will utilize level spreaders followed by a 100-foot riparian buffer on either side of the creek.
XII. Sewage Disposal (required by DW.Q)
Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of
wastewater generated from the proposed project, or available capacity of the subject facility.
Sanitary Sewer
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No.
Is this an after-the-fact permit application? Yes ? No
Page 8 of 9
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 site
will only contain 25% impervious surface following construction and level spreaders will used to
protect downstream water quality. The adjacent parcels have already been developed, therefore,
we do not believe that the development of this site will negatively affect downstream water
quality,
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).

OPERATIONS AND MAINTENANCE MANUAL
HOLLOMAN TRACT DRY DETENTION COMPONENT
OF ALTERNATE LEVEL SPREADER
This manual establishes procedures for maintenance and operation of the [project
name] dry ponds in accordance with the Town of Cary guidelines as set forth in the LDO
Chapter 4.4.6.
MAINTENANCE OF DRY PONDS
Vegetation-The pond areas have a ground cover of fescue, which if properly
maintained will prevent erosion of the embankment and provide an easy surface for
inspection. The grass will be most difficult to obtain in the area subject to water level
fluctuation. Fertilizer use should be kept to a minimum.
Re-Seeding-Peri odic re-seeding may be required to establish grass on areas where
seed did not take or have been destroyed. Before seeding, fertilizer (12-12-12) should
be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be
evenly sown at a rate of three pounds per 1,000 SF. The seed should be covered with
soil to the depth of approximately W. Immediately following the planting, the area
should be mulched with straw.
Trees and Shrubs-Trees, shrubs and other landscape vegetation should be permitted
only as shown on the approved planting plan. The vegetation should be kept healthy
- 4e
and vibrant. If a tree or shrub dies it should be removed and replaced with another tree
or shrub from the same species (see attached maintenance schedule).
Mowing-Grass mowing,' brush cutting and removal of weed vegetation will be
necessary for the proper maintenance of the areas. All area slopes and vegetation
should be mowed when the grass exceeds 8" in height. Acceptable methods include
the use of weed whips or power brush cutters and mowers.
Erosion-Erosion occurs when the water concentrates causing failure of the vegetation
or when vegetation dies and sets up the environment for rill erosion and eventually
gullies from the stormwater runoff. The areas should be inspected. Proper care of
vegetative areas that develop erosion is required to prevent more serious damage to
the site. Rills and gullies should be filled with suitable soil compacted and then seeded.
Methods described earlier on vegetation should be used to properly establish the grass
surface. Where eroded areas are detected, the cause of the erosion should be
addressed to prevent a continued maintenance problem. Frequently, problems result
from the concentration of runoff to one point of the bio-retention area instead of a
uniform distribution of runoff. This can be corrected by reshaping, to more evenly
distribute the runoff to areas not experiencing erosion problems.
Rodent Control-Generally in this urban environment, rodents are not a problem.
Rodents such as groundhogs, muskrats and moles are attracted to moist, wet areas
and can be quite dangerous to structural integrity and proper performance of the
earthwork and drainage. Groundhogs and muskrats thrive on burrowing into the
manmade earthwork, which become pathways for seepage. In the event that burrows
are detected, the rodents should be dealt with by removal.
i
Trash and Debris--Trash acts as a barrier to stormwater infiltration and attracts
unwanted pests. The bio-retention area should be kept clear of debris such as loose
bottles, cans, food containers and other forms of rubbish. The area should be cleared
of debris as needed, but no less than twice a year.
MAINTENANCE OF SPILLWAYS AND CONTROL STRUCTURE
Inspection of Conduits--Conduits should be inspected thoroughly once a year. Conduits
should be visually inspected at the joints. Pipes should be inspected for proper
alignment (sagging), elongation and displacement at joints, cracks, leaks, surface wear,
loss of protective coating, corrosion and blocking. Problems with conduits most often
occur at joints and special attention should be given to them during inspection. Joints
should be checked for gaps caused by elongation or settlement and loss of joint filler
material. Open joints can permit erosion of the earthwork and possibly the piping of soil
material through the joints. 'iA depression in the soil surface over the pipe may be signs
that soil is being removed from around the pipe.
OPERATION
Drainpipes--Drainpipes should always be operable so that the water can be drawn down
in the event of severe rain or for repairs or maintenance.
Record Keeping--Operation of bio-retention area should include recording of the
following:

Annual Inspection Reports--A collection of written inspection reports should be
kept on record in Section IV of this manual. Inspection should be conducted
annually. Copies should be provided to the Town of Cary Stormwater
Management Section of the Engineering Department.
i
Observations--All observations should be recorded. Where periodic inspections
are performed following significant rainfall, these inspections should be logged
into the Periodic Inspection, Operations and Maintenance Form in Section IV of
this manual.
Maintenance--Written records of maintenance and/or repairs should be recorded
on the Periodic Inspection, Operation and Maintenance Form in Section IV of this
manual.
Other Operational Procedures--The owner should maintain a complete and up-to-date
set of plans (as-built drawings) and all changes made to the bio-retention area over time
should be recorded on the as-builts.
Sedimentation and Dredging--Sedimentation from on-site and off-site soils will
eventually result in the clogging of drainage conduits and will have to be removed. The
frequency of this sediment removal can be reduced by ensuring that the site areas
around the building be stabilized with a vegetative ground cover such that it restrains
erosion. This would include a periodic application of fertilizer and/or other treatment
necessary to promote a stable ground cover and minimize sedimentation to the pond.
The removed material should be hauled offsite to a suitable landfill site or mounded
somewhere on site and stabilized with a ground cover sufficient to restrain erosion.

On-Site Determination for Applicability to the Neuse River Riparian Area Protection Rules
(15A NCAC 2B.0233)-EXPRESS REVIEW PROGRAM
Dear Mr. Preuninger:
On August 1, 2005, at your request I conducted an on-site determination to review two features
located on the subject property for applicability to the Neuse Buffer Rules (15A NCAC 2B
.0233). The features are labeled as "A and B" on the attached maps initialed by me on August 1,
2005.
The Division of Water Quality (DWQ) has determined that the features labeled as "A and
B" on the attached maps are subject to the Neuse Buffer Rule. The origin of the features
have been delineated and identified in the field as the following: Feature A starts at flag
#A1; Feature B is subject throughout the property. Please Note: All other features shown on
either map were not contested and therefore remain subject to the Neuse Buffer Rule. These
stream features and their associated buffers should be identified on any future plans for this
property. The owner (or future owners) should notify the DWQ (and other relevant agencies) of
this decision in any future correspondences concerning this property. This on-site determination
shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred to
the Director in writing c/o John Dorney, DWQ Wetlands/401 Unit, 2321 Crabtree Blvd.,
Raleigh, NC 27604-2260. Individuals that dispute a determination by the DWQ or Delegated
Local Authority that "exempts" a surface water from the buffer rule may ask for an adjudicatory
hearing. You must act within 60 days of the date that you receive this letter. Applicants are
hereby notified that the 60-day statutory appeal time does not start until the affected party
(including downstream and adjacent landowners) is notified of this decision. DWQ recommends
that the applicant conduct this notification in order to be certain that third party appeals are made
in a timely manner. To ask for a hearing, send a written petition, which conforms to

Dear Mr. Matthews and Ms. Karoly,
On behalf of John Wieland Homes, we are requesting authorization from the USACE to use
NWP 39 for the installation of a roadway. We are also requesting 401-certification from the
NC-DWQ and buffer compliance for road construction, utility line installation and a greenway
trail.
The site is located in Cary, on the west side of Harrison Avenue (SR 1652), just south of the
intersection of Homestead Drive and Harrison Avenue and is approximately 20.5 acres in
size. The project is located in the Neuse Basin and contains un-named tributaries to
Crabtree Creek. A wetland delineation was conducted by Withers & Ravenel in August of
2005. Data forms are included with the attachments in support of our delineation. Site
meetings were conducted with the NC-DWQon August 5, 2005 (DWQ# 05-1309). The
Hydrologic Unit Code for this basin is 030202o1. The Water Quality classification is B-NSW,
stream index 27-33-(3.5)•
The current request is for 149 linear feet of unimportant stream impact and 0.45 acres of
riparian buffer impact (see the attached maps and PCN for a detailed accounting of the
buffer impacts). Because the impacts are less than 150 linear feet and because the buffer
impacts are less than 0.33 acres at the road crossing, we do not believe that mitigation will
be required. If mitigation is required, the applicant proposes payment to the NC-EEP. Please
note that the applicant proposes parallel impacts to Zone 2 of the riparian buffer for utility
line installation and for a second level spreader. The utility line impacts are necessary due
to topographic constraints and additional level spreaders are needed to provide diffuse flow
along steep slopes. The level spreaders have been designed as per the DWQ guidelines and
we have included the DWQ level spreader worksheets.
Please feet free to call if you have questions or require additional information.

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.

8. Pond Creation
If construction of ; a pond is proposed, associated wetland and stream impacts should be
included above in the wetland and stream impact sections. Also, the proposed pond should
be described here and illustrated on any maps included with this application.
Pond to be created in (check all that apply): ? uplands ? stream ? wetlands

draw-down valve or spillway, etc.): NA
Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): NA
Current land use in the vicinity of the pond: NA
Size of watershed draining to pond: NA Expected pond surface area: NA
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 stream bisects the property
and the impacts could not be avoided in order to access the entire parcel However, impacts to
the stream channel were minimized through the use of headwalls. The parallel impacts to the
buffer are needed for the utility line installation due to the topography and the depth of the sewer
if it were placed completely outside of the buffer.
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
Page 5 of 9
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
fof 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.html.
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.
Because the impacts are to an unimportant channel and because the impacts are less than
150 linear feet we do not believe that mitigation should be required. If mitigation is
required the applicant proposes payment to the NC-EEP
t
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP)., Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrap/index.htm. If use of the NCEEP is proposed, please
check the appropriate box on page five and provide the following information:
Amount of stream mitigation requested (linear feet): NA
Amount of buffer mitigation requested (square feet): NA
Amount. of Riparian wetland mitigation requested (acres): NA
Amount of Non-riparian wetland mitigation requested (acres): NA
Amount of Coastal wetland mitigation requested (acres): NA

X. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ)
It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to
required state and local buffers associated with the project. The applicant must also provide
justification for these impacts in Section VII above. All proposed impacts must be listed herein,
and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a
map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ
Regional Office may be included as appropriate. Photographs may also be included at the
applicant's discretion.

Donation of Property, Riparian Buffer Restoration / Enhancement, or Payment into the
Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B.0242 or.0244, or.0260. NA
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss stormwater
controls proposed in order to protect surface waters and wetlands downstream from the property. If
percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed
impervious level. The site does not currently, contain impervious surface following construction the site
will contain approximately 25% impervious A detailed accounting of the impervious surface is included
with the attachments Because the impervious is less than 30% we do not believe that a stormwater
management plan is required by the NC-DWQ In order to protect water quality downstream, the
applicant will utilize level spreaders followed by a 100-foot riparian buffer on either side of the creek.

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 site
will only contain 25% impervious surface following construction and level spreaders will used to
protect downstream water quality. The adjacent parcels have already been developed, therefore,
we do not believe that the development of this site will negatively ively affect downstream water
uq_ality.
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).

OPERATIONS AND MAINTENANCE MANUAL
i
HOLLOMAN TRACT DRY DETENTION COMPONENT
OF ALTERNATE LEVEL SPREADER
This manual establishes', procedures for maintenance and operation of the [project
name] dry ponds in accordance with the Town of Cary guidelines as set forth in the LDO
Chapter 4.4.6.
MAINTENANCE OF DRY PONDS
Vegetation-The pond areas have a ground cover of fescue, which if properly
maintained will prevent erosion of the embankment and provide an easy surface for
inspection. The grass will be most difficult to obtain in the area subject to water level
fluctuation. Fertilizer use should be kept to a minimum.
Re-Seeding-Peri odic re-seeding may be required to establish grass on areas where
seed did not take or have been destroyed. Before seeding, fertilizer (12-12-12) should
be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be
evenly sown at a rate of three pounds per 1,000 SF. The seed should be covered with
soil to the depth of approximately '/4". Immediately following the planting, the area
should be mulched with straw.
Trees and Shrubs-Trees, shrubs and other landscape vegetation should be permitted
only as shown on the approved planting plan. The vegetation should be kept healthy

and vibrant. If a tree or shrub dies it should be removed and replaced with another tree
or shrub from the same species (see attached maintenance schedule).
Mowing-Grass mowing,, brush cutting and removal of weed vegetation will be
necessary for the proper' maintenance of the areas. All area slopes and vegetation
should be mowed when the grass exceeds 8" in height. Acceptable methods include
the use of weed whips or power brush cutters and mowers.
Erosion-Erosion occurs when the water concentrates causing failure of the vegetation
or when vegetation dies '':and sets up the environment for rill erosion and eventually
gullies from the stormwater runoff. The areas should be inspected. Proper care of
vegetative areas that develop erosion is required to prevent more serious damage to
the site. Rills and gullies should be filled with suitable soil compacted and then seeded.
Methods described earlier,, on vegetation should be used to properly establish the grass
surface. Where eroded areas are detected, the cause of the erosion should be
addressed to prevent a continued maintenance problem. Frequently, problems result
from the concentration of runoff to one point of the bio-retention area instead of a
uniform distribution of runoff. This can be corrected by reshaping, to more evenly
distribute the runoff to areas not experiencing erosion problems.
Rodent Control-Generally in this urban environment, rodents are not a problem.
Rodents such as groundhogs, muskrats and moles are attracted to moist, wet areas
and can be quite dangerous to structural integrity and proper performance of the
earthwork and drainage.'! Groundhogs and muskrats thrive on burrowing into the
manmade earthwork, which become pathways for seepage. In the event that burrows
are detected, the rodents should be dealt with by removal.
Trash and Debris--Trash' acts as a barrier to stormwater infiltration and attracts
unwanted pests. The bio- ' retention area should be kept clear of debris such as loose
bottles, cans, food containers and other forms of rubbish. The area should be cleared
of debris as needed, but no less than twice a year.
MAINTENANCE OF SPILLWAYS AND CONTROL STRUCTURE
Inspection of Conduits-Conduits should be inspected thoroughly once a year. Conduits
should be visually inspected at the joints. Pipes should be inspected for proper
alignment (sagging), elongation and displacement at joints, cracks, leaks, surface wear,
loss of protective coating, ;corrosion and blocking. Problems with conduits most often
occur at joints and special! attention should be given to them during inspection. Joints
should be checked for gaps caused by elongation or settlement and loss of joint filler
material. Open joints can permit erosion of the earthwork and possibly the piping of soil
material through the joints! A depression in the soil surface over the pipe may be signs
that soil is being removed from around the pipe.
OPERATION
Drainpipes-Drainpipes should always be operable so that the water can be drawn down
in the event of severe rain or for repairs or maintenance.
Record Keeping--Operation of bio-retention area should include recording of the
following:
_,
Annual Inspection Reports--A collection of written inspection reports should be
kept on record in Section IV of this manual. Inspection should be conducted
annually. Copies should be provided to the Town of Cary Stormwater
Management Section of the Engineering Department.
Observations--All observations should be recorded. Where periodic inspections
are performed following significant rainfall, these inspections should be logged
into the Periodic Inspection, Operations and Maintenance Form in Section IV of
this manual.
Maintenance--Written records of maintenance and/or repairs should be recorded
on the Periodic Inspection, Operation and Maintenance Form in Section IV of this
manual.
Other Operational Procedures--The owner should maintain a complete and up-to-date
set of plans (as-built drawings) and all changes made to the bio-retention area over time
should be recorded on the as-builts.
Sedimentation and Dredging--Sedimentation from on-site and off-site soils will
eventually result in the clogging of drainage conduits and will have to be removed. The
frequency of this sediment removal can be reduced by ensuring that the site areas
around the building be stabilized with a vegetative ground cover such that it restrains
erosion. This would include a periodic application of fertilizer and/or other treatment
necessary to promote a stable ground cover and minimize sedimentation to the pond.
The removed material should be hauled offsite to a suitable landfill site or mounded
somewhere on site and stabilized with a ground cover sufficient to restrain erosion.

On-Site Determination for Applicability to the Neuse River Riparian Area Protection Rules
(15A NCAC 2B .0233)-EXPRESS REVIEW PROGRAM
Dear Mr. Preuninger:
On August 1, 2005, at your request I conducted an on-site determination to review two features
located on the subject property for applicability to the Neuse Buffer Rules (15A NCAC 2B
.0233). The features are labeled as "A and B" on the attached maps initialed by me on August 1,
2005. f
The Division of Water Quality (DWQ) has determined that the features labeled as "A and
B" on the attached maps are subject to the Neuse Buffer Rule. The origin of the features
have been delineated and identified in the field as the following: Feature A starts at flag
#A1; Feature B is subject throughout the property. Please Note: All other features shown on
either map were not contested and therefore remain subject to the Neuse Buffer Rule. These
stream features and their associated buffers should be identified on any future plans for this
property. The owner (or future owners) should notify the DWQ (and other relevant agencies) of
this decision in any future correspondences concerning this property. This on-site determination
shall expire five (5) years from the date of this letter.
Landowners or affected parties that dispute a determination made by the DWQ or Delegated
Local Authority that a surface water exists and that it is subject to the buffer rule may request a
determination by the Director. A request for a determination by the Director shall be referred to
the Director in writing c/o John Dorney, DWQ Wetlands/401' Unit, 2321 Crabtree Blvd.,
Raleigh, NC 27604-2260. Individuals that dispute a determination by the DWQ or Delegated
Local Authority that "exempts" a surface water from the buffer rule may ask for an adjudicatory
hearing. You must act within 60 days of the date that you receive this letter. Applicants are
hereby notified that the 60-day statutory appeal time does not start until the affected party
(including downstream and adjacent landowners) is notified of this decision. DWQ recommends
that the applicant conduct this notification in order to be certain that third party appeals are made
in a timely manner. To ask for a hearing, send a written petition, which conforms to
