UT to Crabtree Creek [03-04-02, 27-33-(1), C NSA] *303(d) list
APPROVAL of 401 Water Quality Certification and AUTHORIZATION CERTIFICATE per the
Neuse River Buffer Protection Rules (15A NCAC 2B .0233) with ADDITIONAL CONDITIONS
EXPRESS REVIEW PROGRAM
Dear Mr. Methven:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.1273 acres of wetlands (temporary), 195 feet of streams and 5,532 square
feet (ft2) of protected riparian buffers for the purpose of a subdivision at the subject property, as described
within your application dated December 22, 2004 and received by this office on December 22, 2004 and
all other additional information submitted and received by this office on January 4, 2005, January 12,
2005 and January 20, 2005. Please note that this excludes the impacts requested for impact #9. After
reviewing your application, we have decided that the impacts are covered by the N.C. Division of Water
Quality (DWQ) General Water Quality Certification Number 3402 (GC3402). The Certification allows
you to use Nationwide Permit 39 when issued by the US Army Corps of Engineers (USAGE). This letter
shall also act as your approved Authorization Certificate for impacts to the protected riparian buffers per
15A NCAC 2B .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.
Conditions:
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:
Amount Approved
(Units) Plan Location or Reference
Stream 195 (feet) Sheet 2 and 3 (impacts 2 and 6)
404 Wetlands 0.1273 (acres) Sheet 1 (impact 4)
Buffers 5,532 (square ft.) Sheet 2 and 4 (impacts 7 and 8)
2. Buffer Mitigation (EEP)
You are required to mitigate for impacts to the protected riparian buffers. The required area of
mitigation to compensate for impacts to the protected riparian buffers is 5,532 square feet as required
under. this Authorization Certificate and 15A NCAC 2B .0242. We understand that you wish to make a
payment into the Riparian Buffer Restoration Fund administered by the NC Ecosystem Enhancement
Program (EEP) to meet this mitigation requirement. This has been determined by the DWQ to be a
suitable method to meet the mitigation requirement. In accordance with 15A NCAC 2B .0242(7) this
contribution will satisfy our compensatory mitigation requirements under 15A NCAC 2B .0233(10).
Until the EEP receives and clears your check (made payable to: DENR - Ecosystem Enhancement
Program Office), no impacts specified in this Authorization. Certificate shall occur. The EEP should be
contacted at [phone] if you have any questions concerning payment into the Riparian Buffer
Restoration Fund. You have one month from the date of this approval to make this payment. For
accounting purposes, this Authorization Certificate authorizes payment into the Riparian Buffer
Restoration Fund to compensate for 10,329 ft2 of required riparian buffer mitigation for impacts
to 5,532 fe of riparian buffers; 03-04-02 river and subbasin: '
3. Diffuse Flow
All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected stream
buffers and will not re-concentrate before discharging into the stream as identified within 15A NCAC
2B .0233(5).
4. 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.
5. No Impacts to Zone 1
No impacts shall occur to Zone 1 of the protected riparian buffers (except for uses and activities
designated as "exempt" within 15A NCAC 02B .0233), unless otherwise approved by the DWQ.
6. 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-
Centex Homes
Page 3 of 5

established or, if the pipes installed in a perched manner, the pipes shall be removed and re-installed
correctly.
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 stream beds 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.
7. For the proposed 4 barrel culvert located at impact #6, the design and installation of sills in
conjunction with multiple barrel culverts should be such that the culvert cross-section mimics the
stream bankfull dimension (i.e. stream cross sectional area and geometric configuration) as closely as
possible. The sills shall be placed on the two outside culverts and have a height equal to the bankfull
discharge depth. No impacts shall be incurred anywhere on the project until an acceptable design is
submitted to, and approved by, the NC Division of Water Quality.
It is our understanding that a 48" pipe is being required for impact #2. Culverts 48" diameter or
greater shall be buried a foot and parallel to the slope of the streambed. Culverts less than 48" in
diameter or less shall be buried to a depth equal or greater than 20% their size for aquatic life
passage. These measurements must be based on natural thalweg depths.
9. Impervious Surface Condition
If the amount of impervious surface exceeds 30%, then a stormwater management plan, approved by
DWQ, shall be implemented. The DWQ has not approved the proposed stormwater management
plan, included in the application dated 22 December 2004.
10. Construction Stormwater Permit NCGO10000
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 (NCGO10000) 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 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. uslsulFonnsDocuments. htm.
11. 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/ncwetlarids. The text of the sample deed notification may be modified as
appropriate to suit to this project.
Centex Homes

12. 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.
13. 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 Preconstruction Notice Application. 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.
14. 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.
15. Notification of Construction
The applicant and/or authorized agent shall contact the DWQ Express Review Program in writing at
the letterhead address within 10 days of the commencement of construction.
16. Certificate of Completion

Dear Ms. Edwards:
We received your fax sent January, 06 of 2005, requesting (for a second time), additional
information for proposed project referenced above. This letter and the accompanying
information should clarify material already submitted with our original request for
Express Review, and answer your request for additional information.
1. You requested that we "submit cross-sectional details for road crossing # 2,
including the size of the culvert, the length of the culvert, the velocities coming
out of the culvert and the size of the dissipater," as well as showing, "provision
for aquatic life passage for this stream crossing."
Attached to this letter are the details requested (Impact Maps Sheet 5 & 6). Also attached
area response letter written by Tommy Craven and a letter of resolution from the Town
of Morrisville which explains the restrictions imposed on the culvert specifications for
the crossing at Impact # 2. Please refer to these attachments for additional details.
2. You requested that the proposed impacts #1 and #3 be eliminated as they were not
necessary.
These impacts have been eliminated. Please see the updated PCN and Impact Maps,
(attached).
3. You requested that impact #9 be moved or reconfigured.

Phone: [phone] Phone: [phone]
Fax: [phone] Fax: [phone]
This impact is unavoidable and justification has been provided in the attached response
letters and the letter of resolution from the Town of Morrisville.
4. You asked that "the impact labeled as #6 on the impact map does not match the
impacts listed in the PCN," and to "revise the map to include impacts to scale.
These changes have been made to the impact maps. The attached maps and PCN should
be in alignment with each other.
5.' You stated that you believe "that the proposed impact labeled on the plans as #5
can be moved or reconfigured to avoid the impacts to the wetland." You asked us
to "revise the plans to avoid the impacts."
The impact previously labeled as #5 has been eliminated entirely. The lot configuration
was re-designed to completely eliminate impacts to thewetland. This change has been
reflected on the PCN and Impact Maps.
6. You requested that the impacts labeled on the map as #7 and #8 be moved or
reconfigured to avoid buffer impacts.
The stormwater devices have been removed from Zone 1 with the exception of the outlet
pipe from the devices. Mitigation will be necessary for remaining impacts to buffers.
7. You requested that the stomwater from the outlet near lots #160 and #166 be
treated. And that the outlet pipe from the stormwater management facility labeled
#7 be directed into the constructed wetland.
The stormwater from this site is not required to be treated as the projects impervious
surface percentage is only,27.7%. Please refer to the attached response letters (section 7)
for more details.
8. You'requested that the road crossing at impact #6 "be redesigned to prevent the
potential for headcuts and provide aquatic life passage."
Justification for this impact has been provided in the attached response letter and the
letter of resolution from the Town of Morrisville. Please refer to these letters. for the
details regarding the justification for the proposed road crossing labeled on the maps as
impact #6.
8. You.stated that the volumes provided for the temporary storage in stormwater
management facilities #'sl, 2, and 4 are significantly undersized. You asked that
the size be recalculated and"designed in accordance with the NCDENR 199
Stormwater BMP Manual.
Again, water quality treatment is not required for this site. Water quality pool storage
volumes were based on capturing the onsite runoff from the one inch storm. The volume
was calculated using the SCS curve number methodology for each of the land use
classifications within the site. Please refer to the attached response letter for additional
justification.
Please do not hesitate to contact us in the event that we have misinterpreted or
misunderstood your request for additional information.

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.
On 11 September 2001, Mr. Charles Brown of NC DWQ determined the applicability of the
Neuse Buffer Rules to jurisdictional features on the subject property (NBRRO 01-259). A
feature at the northern property line starts approximately 25 feet inside the western property line
and terminates approximately 50 feet west of the utility easement that is present on site. This
feature becomes subject again at a point west of the utility easement and south of the proposed
road crossing The other east-flowing stream on site enters the property in the southwest
property corner, and is buffered throughout its extent on site to its confluence with a UT to
y
Indian Branch That UT to Indian Branch flows on site within 200 feet of the southeast propert
corner, and is buffered throughout its extent on site. The USACE approved the wetland
delineation on 8 January 2002 USACE Action ID #200220371) after reviewing the fieldwork
conducted by S&EC Earlier phases of the project are shown and impacted 0.071 acres of
wetland Because this area was below 0.10 acre and the project has not been completed,
notification to the USACE/NC DWQ has not previously been submitted to S&EC's knowledge.
V. Future Project Plans

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 annlicant has taken several steps to minimize impacts where- they are unavoidable. Road
crossings have been re-engineered: others have been eliminated, and cul-de-sacs created in their
place in order to avoid crossing additional jurisdictional features present on the site. The main
road crossing (Impact 6) was shifted "upstream" so as to avoid the buffered area and to use an
existing, crossing within the utility easement. For additional impact Justification refer to the copy
of the Attached Response Letters
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
Page 5 of 9
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 March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP 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
ho://h2o.enr.state.nc.us/ncwetlands/strmpide.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.
Impact 6 is a road crossing of a perennial stream that is within the utility line easement on
the property. Impacts in this area were minimized by utilizing an old crossing within the
access and by crossing upstream of where the channel becomes buffered. Although this
channel contains water most of the year it has been greatly impacted by the easement and
therefore is not considered "important/mitigatable". For this reason we do not believe that
stream mitigation should be required. All buffer impacts proposed are considered
"allowable" or "exempt" and therefore no buffer mitigation is proposed. If the USACE
requires wetland mitigation the applicant proposes payment to the NC EEP.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet):
Page 6 of 9
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): NA
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
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.
Yes ? No ?
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.
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 213 .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify )?
Yes ® No ? If you answered "yes", provide the following information:
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.
Zone* Impact
(square feet Multiplier Required
Miti ation

Page 7 of 9
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
** All proposed activities resulting in impacts to the riparian buffers are considered "Allowable"
or "Exempt" by the buffer rules.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or .0260.
All proposed activities resulting in impacts to the riparian buffers are considered "Allowable" or
"Exempt" by the buffer rules
XI. Stormwater (required by DWQ)
Describe impervious acreage (both 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.
Impervious surface area on site equals 27.71% (i.e. less than 30%). For this reason, an NC
DWQ-approved stormwater plan is not required Proposed stormwater devices are, however,
shown on the previously, provided stormwater management plan (4 sheets) and impact mans (5
sheets)
XII. Sewage Disposal (required by DWQ)
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.

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
XIV. 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).

REQUEST FOR MORE INFORMATION EXPRESS REVIEW PROGRAM
Dear Mr. Methven:
On January 4, 2005, the Division of Water Quality (DWQ) received your new information for
the application dated December 22, 2004 to impact 0.374 acres of wetlands, 286 feet of stream
and 9,039 square feet (ft) of protected riparian buffers to construct the proposed subdivision.
The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to
process your application to impact protected wetland, streams and/or buffers on the subject
property. Therefore, unless we receive the additional information requested below, we will have
to move toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8)
and will place this project on hold as incomplete until we receive this additional information.
Please provide 5 copies of the following information so that we may continue to review your
project.
Additional Information:
1. Please submit cross-sectional details for road crossing # 2, this should include the size of the
culvert, the length of the culvert, the velocities coming out of the culvert and the size of the
dissipater. In addition, please show provision for aquatic life passage for this stream crossing.
2. The proposed impacts labeled as #1 and #3 on the plans does not appear to be necessary.
Please eliminate the proposed impacts or provide additional information as to why it is
necessary for this project.
3. This office believes that the proposed impact labeled on the plans as #9 can be moved or
reconfigured to avoid the impacts to the wetland. Please revise the plans to avoid the impacts.

Re : The Gardens at Town Hall Commons
DWQ EXP No. 04-1983
Dear Ms. Karoly :
In response to your comments regarding The Gardens at Town Hall Commons we
offer the following :
1. We have revised the plans for crossing number 2 to indicate the requested
details.
2. We have revised the plans in this area to eliminate the impacts on lots 151,
152, 154, 155, 157 and 158. The location of the road in front of lot 133 was
set in order to minimize the impact due to the road construction. However
we are unable to configure the lots west of the road to eliminate the impacts
upstream without losing a lot. The loss of this lot will greatly diminish the
project's viability. In light of the modification to the plan to eliminate the
impacts on the more significant wetlands downstream, we ask that you
consider the minimal incremental impact upstream of the road crossing to
necessary to construct lot 133.
3. The Town of Morrisville has required that this crossing be made and that
while it may ostensibly be utilized as a pedestrian access, it must also provide
a secondary access to the recreation center for emergency service vehicles as
well as additional access to the sanitary sewer lines in this area for the Town's
maintenance trucks. Therefore a less obtrusive wooden footbridge will not
provide the required access. We have tried to keep the fill for the path at a
minimum in order to minimize the wetlands impact and to avoid creating a
significant hydraulic obstruction to floodwaters along the creek. Placing
fewer culverts in this crossing would require that the culvert sizes be
increased, raising the elevation of the path, and increasing the size of both the
wetland impact and the hydraulic obstruction to the stream flows.
Ms. Cyndi Karoly
January 11, 2005
Page 2
4. We have changed the impact table to present the information as you have
requested.
5. We have revised the plans to remove the stormwater device from the
wetlands.
6. We have revised the plans to remove the stormwater devices from Zone 1
with the exception of the outlet pipe from the devices. We understand that a
mitigation fee will be necessary for the basin to be located within Zone 2 of
the buffers, and for the impact of the outlet pipe within Zone 1.
7. Actually this stormwater is not required to be treated. The impervious surface
area of the project is 27.7% of the tract size, so 85% TSS removal is not
required. The Town of Morrisville requires stormwater detention to pre-
development release rates for the two and ten year storms, but has no water
quality component to their ordinance. Centex Homes voluntarily chose to
provide water quality treatment above and beyond the requirements. Centex
Homes has nonetheless instructed us to add another extended detention
wetlands in this location that will serve both water quality and water quantity
functions.
8. Our situation at crossing number 6 is very similar to the problem at the
upstream pedestrian crossing. Hydraulically there is not a well defined
channel at this location. There is however, a fairly significant urbanizing
drainage area of approximately 102 acres draining to this point. Given the
Town of Morrisville's minimum cover requirements for fill over the top of the
culverts, the maximum size culvert that can fit under the roadway is 48 inches
in diameter. In order to safely pass the required 100 year design storm under
the roadway, four, 48 inch culverts are required. Raising the roadway to
allow for a larger center culvert would only increase the length and area of the
impact. We have also called for the use of headwalls at the crossing to further
minimize the length of the impact. It is our firm belief that the proposed
design minimizes the impacts while meeting the hydraulic requirements
necessary to provide for the public safety and welfare.
9. As outlined in item 7 above water quality treatment is not required for this
site. We chose to provide water quality pool storage volumes based on
capturing the onsite runoff from the one inch storm. The volume was
calculated using the SCS curve number methodology for each of the land use
classifications within the site. The volume of runoff from each land use was
then summed to produce the total. This is the same methodology that is used
Ms. Cyndi Karoly
January 11, 2005
Page 3
by Dr. Bill Hunt in his instructional seminars and is in compliance with all SCS
procedures. These volumes are typically lower than the volumes determined
using Schueler's "Simple Method" outlined in the BMP Manual. They are
however based on the most sound and established procedures available and the
results have a greater confidence level than those obtained using the "Simple
Method". The BMP Manual goes on to state that methods other than the
"Simple Method" may be used to determine the volume of runoff. We have
expanded the calculations to better illustrate how this runoff volume was
determined.
We are currently revising the plans and calculations to document these changes.
These revisions should be complete and submitted for your review by the end of this
week.
Please do not hesitate to contact Sean Clark at S&EC, or me with any questions of
comments regarding our response.

dedication of land.
4. The developer shall be responsible to construct a ten-foot (10'.) wide asphalt multi-
purpose trail from the end of Olde Courthouse Way north to the future greenway, which
shall also serve as the access to the detention pond behind lot #151; and
WHEREAS, the Board of Commissioners, which is authorized to approve or disapprove
the proposed Preliminary Plat, did receive the Planning and Zoning Board's recommendation at
their Briefing Meeting on June 9, 2003; and
WHEREAS, the Town's Subdivision Ordinance is, in part, intended "to promote the
public health, safety, and general welfare of the community"; and
WHEREAS, Section 107, Appendix D, of the North Carolina State Fire Prevention
Code, 2002 Edition, as adopted by the Town of Morrisville in its entirety, states, in part, that:
"Development of one- or two-family dwellings where the number of dwelling units exceeds 30
shall be provided with separate and approved fire apparatus access roads, and shall meet the
requirements of Section D104.3"; and
NOW, THEREFORE, BE IT RESOLVED by the Board of Commissioners of the
Town of Morrisville that:
The proposed Preliminary Plat for The Gardens at Town Hall Commons, Phase 3, is
approved subject to the following conditions:
1. The developer shall provide inflow and outflow hydrographs and stage-storage
calculations to verify the adequacy of the detention pond storage.
2. Construction access to the site shall not be permitted from Garden Square Lane.
Construction access to the site shall be permitted over a temporary road to be provided
prior to the commencement of any construction. This temporary construction access
road may be built on a private easement, and its use may be limited in any manner agreed
upon by the parties to that easement, so long as it is the sole access to the site used for
construction purposes. The temporary construction access road shall be constructed in
accordance with all relevant regulations and design requirements in effect on the date of
this resolution, and shall be approved by the Town if found in compliance with those
regulations and design requirements. All construction related vehicular traffic must use
this road in order to ingress and egress "The Gardens at Town Hall Commons, Phase 3."
3. The developer may provide a fee-in-lieu of dedication rather than the proposed
dedication of land for recreation. Centex Homes and the Town may continue to
negotiate terms for meeting the dedication requirement found in Article VIII of the
Subdivision Ordinance until the Final Plat is recorded.
4. The developer shall be responsible to construct a ten-foot (10') wide asphalt multi-
purpose trail from the end of Olde Courthouse Way north to the future greenway, which
shall also serve as the access to the detention pond behind lot #151. The developer may
also use a bridge as necessary to cross wetlands.
5. Prior to the issuance of the first certificate of occupancy for any residential dwelling
unit built in this development, a new, second access for the purpose of ingress and egress
to and from this development shall be provided. This road shall provide access to the
site in addition to that which will be provided by the extension of Garden Square Lane,

REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
Dear Mr. Methven:
On January 12, 2005, the Division of Water Quality (DWQ) received your new information for
the application dated December 22, 2004 to impact 0.374 acres of wetlands, 286 feet of stream
and 9,039 square feet (ft) of protected riparian buffers to construct the proposed subdivision.
The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to
process your application to impact protected wetland, streams and/or buffers on the subject
property. Therefore, unless we receive the additional information requested below, we will have
to move toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8)
and will place this project on hold as incomplete until we receive this additional information.
Please provide 3 copies of the following information so that we may continue to review your
project.
Additional Information:
1. In the January 6, 2005 Request for More Information letter we requested the following
information but it was not submitted. The DWQ requests that you submit cross-sectional
details for road crossing # 2, this should include the size of the culvert, the length of the
culvert, the velocities coming out of the culvert and the size of the dissipater. In addition,
please show provision for aquatic life passage for this stream crossing.
2. The proposed impacts labeled as #1 on the plans does not appear to be necessary. The DWQ
requests that you eliminate the proposed impact.

Re : The Gardens at Town Hall Commons
DWQ EXP No. 04-1983
Dear Ms. Karoly :
In response to your comments regarding The Gardens at Town Hall Commons we
offer the following :
1. We are unable to set this culvert in order to allow for the passage of aquatic
life. As illustrated on the profile of the street, the existing grade in this area is
low and relatively flat. The stream channel in this area is only a few inches
deep. Our proposed road grade is set at approximately the existing grade.
With the street grades we have proposed, the runoff from the upstream side of
the road must be piped downstream to a lower elevation before it can be
released. To place a culvert in this location that would allow for the passage
of aquatic life would require that the road grade in this area be raised
approximately five feet. This allows for a 48 inch diameter culvert, which is
necessary to pass the expected runoff from upstream properties with a foot of
the culvert submerged, plus meet the requirement of 2 feet of cover over the
culvert. As illustrated on the enclosed graphic, this has a devastating effect on
the lots in this area. Lots 131, 132, 134, 154, 155 and 156 would all be
substantially below the grade of the proposed road, leading to drainage
problems, unsafe driveway connections, and substantially diminished lot
values. The cost of the crossing would increase substantially, with
approximately 2,500 yards of fill material being imported to provide the fill
material necessary to raise this section of the road. The roadway fill on the
upstream and downstream slopes of the fill would cause a total of 134 linear
feet of channel impact, compared with the 85 linear feet required to
accomplish the proposed design.
2. We have modified the plans to delete the proposed impact 1.

3. The PCN has been modified by Soil and Environmental Consultants, Inc.
4. The Town of Morrisville has sent along a copy of the conditions of the
subdivision approval as evidence of this requirement. A copy is attached.
5. As we attempted to explain in the previous response, this is a very difficult
crossing. We have to tie to the existing street that is constructed to within
seventy feet of the proposed creek crossing, and there is not a broad
floodplain or over bank area in the location of the crossing. However, we
have revised the plans for this crossing in accordance with your direction. We
have aligned one pipe to match the upstream and downstream ends of the
wetlands channel at the crossing, and increased the diameter of this culvert to
54 inches in order to help with the hydraulic capacity. The invert of the pipe
is set below the existing streambed. The other culverts will be installed in the
horizontal relationship to the channel culvert that is required by the NCDOT
headwall construction specification, and vertically a half-foot above the invert
of the larger in-channel culvert.
Please do not hesitate to contact Sean Clark at S&EC, or me with any questions of
comments regarding our response.

2321 Crabtree Blvd, Suite 250
Raleigh, NC 27604
Re : The Gardens at Town Hall Commons
DWQ EXP No. 04-1983
Dear Ms. Edwards / Ms. Karoly :
In response to your comments regarding The Gardens at Town Hall Commons we
offer the following :
1. We have revised the plans for crossin number 2 to indicate the requested
details. 0 e? 1
2. We have revised the plans in this area to eliminate the impacts on lots 151,
152, 154, 155, 157 and 158. The location of the road in front of lot 133 was
set in order to minimize the impact due to the road construction. However
we are unable to configure the lots west of the road to eliminate the impacts
upstream without losing a lot. The loss of this lot will greatly diminish the
project's viability. In light of the modification to the plan to eliminate the
impacts on the more significant wetlands downstream, we ask that you
consider the minimal incremental impact "upstream" of the road crossing as
necessary to construct lot 133.
3.
The Town of Morrisville has required that this crossing be made and that
while it may ostensibly be utilized as a pedestrian access, it must also provide
a secondary access to the recreation center for emergency service vehicles as
well as additional access to the sanitary sewer lines in is area or e Town's
maintenance trucks. Therefore a less obtrusive wooden footbridge will not
provide the required utility access. We have tried to keep the fill for the path
at a minimum in order to minimize the wetlands impact and to avoid creating
a significant hydraulic obstruction to floodwaters along the creek. Placing
fewer culverts in this crossing would require that the culvert sizes be
increased, raising the elevation of the path, and increasing the size of both the
wetland impact and the hydraulic obstruction to the stream flows.

Ms. Debbie Edwards / Ms. Cyndi Karoly

Page 2
V4. We have changed the impact table to present the information as you have
requested.
V5• We have revised the plans to remove the stormwater device from the
wetlands.
i.6./We have revised the plans to remove the stormwater devices from Zone 1
with the exception of the outlet pipe from the devices. We understand that a
mitigation fee will be necessary for the basin to be located within Zone 2 of
the buffers.
7. Actually this stormwater is not required to be treated. The impervious surface
area of the project is 27.7% of the tract size, so 85% TSS removal is not
required. The Town of Morrisville requires stormwater detention to pre-
, development release rates for the two and ten year storms, but has no water
quality component to their ordinance. Centex Homes voluntarily chose to
\.,\ provide water quality treatment above and beyond the requirements. Centex
Homes has nonetheless instructed us to add another extended detention
wetlands in this location that will serve both water quality and water quantity
functions.
C 8. Our situation at crossing number 6 is very similar to the problem at the
upstream pedestrian crossing. Hydraulically there is not a well defined
channel at this location. There is however, a fairly significant urbanizing
drainage area of approximately 102 acres draining to this point. Given the
Town of Morrisville's minimum cover requirements for fill over the top of the
culverts, the maximum size culvert that can fit under the roadway is 48 inches
in diameter. In order to safely pass the required 100 year design storm under
the roadway, four, 48 inch culverts are required. Raising the roadway to
allow for a larger center culvert would only increase the length and area of the
impact. We have also called for the use of headwalls at the crossing to further
minimize the length of the impact. It is our firm belief that the proposed
design minimizes the impacts while meeting the hydraulic requirements
necessary to provide for the public safety and welfare.
9. As outlined in item 7 above water quality treatment is not required for this
site. We chose to provide water quality pool storage volumes based on
capturing the onsite runoff from the one inch storm. The volume was
calculated using the SCS curve number methodology for each of the land use
classifications within the site. The volume of runoff from each land use was
then summed to produce the total. This is the same methodology that is used
Ms. Debbie Edwards / Ms. Cyndi Karoly
January 11, 2005
Page 3
by Dr. Bill Hunt in his instructional seminars and is in compliance with all SCS
procedures. These volumes are typically lower than the volumes determined
using Schueler's "Simple Method" outlined in the BMP Manual. They are
however based on the most sound and established procedures available and the
results have a greater confidence level than those obtained using the "Simple
Method". The BMP Manual goes on to state that methods other than the
"Simple Method" may be used to determine the volume of runoff. We have
expanded the calculations to better illustrate how this runoff volume was
determined.
We are currently revising the plans and calculations to document these changes.
These revisions should be complete and submitted for your review by the end of this
week.
Please do not hesitate to contact Sean Clark at S&EC, or me with any questions of
comments regarding our response.

Re : The Gardens at Town Hall Commons
DWQ EXP No. 04-1983
Dear Ms. Edwards / Ms. Karoly :
?o

In response to your comments regarding The Gardens at Town Hall Commons we
offer the following :
1. We have revised the plans for crossing number 2 to indicate the requested
details.
2. We have revised the plans in this area to eliminate the impacts on lots 151,
152, 154, 155, 157 and 158. The location of the road in front of lot 133 was
set in order to minimize the impact due to the road construction. However
we are unable to configure the lots west of the road to eliminate the impacts
upstream without losing a lot. The loss of this lot will greatly diminish the
project's viability. In light of the modification to the plan to eliminate the
impacts on the more significant wetlands downstream, we ask that you
consider the minimal incremental impact "upstream" of the road crossing as
necessary to construct lot 133.
3. The Town of Morrisville has required that this crossing be made and that
while it may ostensibly be utilized as a pedestrian access, it must also provide
a secondary access to the recreation center for emergency service vehicles as
well as additional access to the sanitary sewer lines in this area for the Town's
maintenance trucks. Therefore a less obtrusive wooden footbridge will not
provide the required utility access. We have tried to keep the fill for the path
at a minimum in order to minimize the wetlands impact and to avoid creating
a significant hydraulic obstruction to floodwaters along the creek. Placing
fewer culverts in this crossing would require that the culvert sizes be
increased, raising the elevation of the path, and increasing the size of both the
wetland impact and the hydraulic obstruction to the stream flows.
Ms. Debbie Edwards / Ms. Cyndi Karoly

4. We have changed the impact table to present the information as you have
requested.
5. We have revised the plans to remove the stormwater device from the
wetlands.
6. We have revised the plans to remove the stormwater devices from Zone 1
with the exception of the outlet pipe from the devices. We understand that a
mitigation fee will be necessary for the basin to be located within Zone 2 of
the buffers.
7. Actually this stormwater is not required to be treated. The impervious surface
area of the project is 27.7% of the tract size, so 85% TSS removal is not
required. The Town of Morrisville requires stormwater detention to pre-
development release rates for the two and ten year storms, but has no water
quality component to their ordinance. Centex Homes voluntarily chose to
provide water quality treatment above and beyond the requirements. Centex
Homes has nonetheless instructed us to add another extended detention
wetlands in this location that will serve both water quality and water quantity
functions.
8. Our situation at crossing number 6 is very similar to the problem at the
upstream pedestrian crossing. Hydraulically there is not a well defined
channel at this location. There is however, a fairly significant urbanizing
drainage area of approximately 102 acres draining to this point. Given the
Town of Morrisville's minimum cover requirements for fill over the top of the
culverts, the maximum size culvert that can fit under the roadway is 48 inches
in diameter. In order to safely pass the required 100 year design storm under
the roadway, four, 48 inch culverts are required. Raising the roadway to
allow for a larger center culvert would only increase the length and area of the
impact. We have also called for the use of headwalls at the crossing to further
minimize the length of the impact. It is our firm belief that the proposed
design minimizes the impacts while meeting the hydraulic requirements
necessary to provide for the public safety and welfare.
9. As outlined in item 7 above water quality treatment is not required for this
site. We chose to provide water quality pool storage volumes based on
capturing the onsite runoff from the one inch storm. The volume was
calculated using the SCS curve number methodology for each of the land use
classifications within the site. The volume of runoff from each land use was
then summed to produce the total. This is the same methodology that is used
,r
Ms. Debbie Edwards / Ms. Cyndi Karoly
January 11, 2005
Page 3
by Dr. Bill Hunt in his instructional seminars and is in compliance with all SCS
procedures. These volumes are typically lower than the volumes determined
using Schueler's "Simple Method" outlined in the BMP Manual. They are
however based on the most sound and established procedures available and the
results have a greater confidence level than those obtained using the "Simple
Method". The BMP Manual goes on to state that methods other than the
"Simple Method" may be used to determine the volume of runoff. We have
expanded the calculations to better illustrate how this runoff volume was
determined.
We are currently revising the plans and calculations to document these changes.
These revisions should be complete and submitted for your review by the end of this
week.
Please do not hesitate to contact Sean Clark at S&EC, or me with any questions of
comments regarding our response.

REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
Dear Mr. Methven:
On January 4, 2005, the Division of Water Quality (DWQ) received your new information for
the application dated December 22, 2004 to impact 0.374 acres of wetlands, 286 feet of stream
and 9,039 square feet (ft) of protected riparian buffers to construct the proposed subdivision.
The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to
process your application to impact protected wetland, streams and/or buffers on the subject
property. Therefore, unless we receive the additional information requested below, we will have
to move toward denial of your application as required by 15A NCAC 2H .0506 and 2B .0233(8)
and will place this project on hold as incomplete until we receive this additional information.
Please provide 5 copies of the following information so that we may continue to review your
project.
Additional Information:
1. Please submit cross-sectional details for road crossing # 2, this should include the size of the
culvert, the length of the culvert, the velocities coming out of the culvert and the size of the
dissipater. In addition, please show provision for aquatic life passage for this stream crossing.
2. The proposed impacts labeled as #1 and #3 on the plans does not appear to be necessary.
Please eliminate the proposed impacts or provide additional information as to why it is
necessary for this project.
3. This office believes that the proposed impact labeled on the plans as #9 can be moved or
reconfigured to avoid the impacts to the wetland. Please revise the plans to avoid the impacts.

4. The impact labeled as #6 on the impact map does not match the impacts listed in the PCN,
please revise the map to include impacts to scale.
5. This office believes that the proposed impact labeled on the plans as #5 can be moved or
reconfigured to avoid the impacts to the wetland. Please revise the plans to avoid the impacts.
6. This office believes that the proposed impacts labeled on the plans as #7 and #8 can be moved
or reconfigured to avoid the impacts to the riparian buffers. Please revise the plans to avoid the
riparian buffer impacts.
7. On your impact map, there is a stormwater outlet located on the back of lots #160 and #166
that is not directed to a stormwater management facility. This stormwater is required to be
treated, please revise the stormwater management plans so that this stormwater is being treated.
In addition, the stormwater management facility labeled #7 has the stormwater pipe not
directed into the constructed wetland, please revise your plans.
8. DWQ believes that the proposed design for road crossing #6 will result in destabilization
upstream and will not meet condition #9 in Water Quality Certification #3402. Please redesign
the proposed road crossing to prevent the potential for headcuts and provide aquatic life
passage.
9. The volumes provided for the temporary storage in stormwater management facilities #'s 1, 2
and 4 are significantly undersized. Please recalculate and design in accordance with the
NCDENR 1999 Stormwater BMP manual.
Please respond within four days of the date of this letter by sending this information to me via e-
mail or fax and a follow-up copy in writing. The Express Review Program is a process that
requires all parties to participate in a timely manner. If the DWQ feels the Express Review
Program is the incorrect review program for your project, then we may have to return your
application and have it reviewed through our regular 401 Water Quality Certification Program.
This letter only addresses the application review and does not authorize any impacts to wetlands,
waters or protected buffers. Please 'be aware that any impacts requested within your application
are not authorized (at this time) by the DWQ. Please call Deborah Edwards at [phone] if
you have any questions regarding or would like to set up a meeting to discuss this matter.

RE: DWQ EXP No. 04-1983
The Gardens at Town `Hall Commons
MorrisvilleWake County, North Carolina
-Dear Ms. Edwards:
We received your fax sent the afternoon of Thursday, 23 December 2004, requesting
additional information for proposed project referenced above. This letter and the
accompanying information should clarify material already submitted with our original
request for Express Review, and answer your request for additional information.
l . You requested that we "submit a Pre-construction/Pre-existing conditions map,
this sheet must be scaled and include all jurisdictional and non jurisdictional
wetlands, streams, water features, state regulated buffers, topographic contours
with elevations, approximate extend [sic] and nature of forest, field, landscaped or
other cover. Any existing structures and impervious area must be shown.
Existing roads, culverts,'and other pertinent features must be shown North arrow ,
and the scale must be shown."
We submitted an impact map, including separate sheets at larger scales showing specific
impacts. We did not include the original sign--off map in our submittal, but we included
references to DWQ and USACE site meetings, action IDs, and references to specific
dates that DWQ personnel had visited the-site. The attached "Existing Conditions, Plan"
map shows phases 1 and 2 of The Gardens as well as "The Village" at Town Hall
Commons. The infrastructure of each of these areas is completed and houses have been
constructed, however all of the homes have, not yet been built.

The area shown on-the map labeled ""Impact, Drainage, and Assumed Built-out Plan"
depicts the proposed site plan at a 1:60 scale. The structures/infrastructure depicted on
this plan has not begun. The area within Phase 3 is currently in various succesioinal
stages of revegetation ` The upland areas are mostly mixed stands of loblolly pine,
sweetgum, and red maple. The wetland areas outside of the utility easement are mostly
made up of larger deciduous trees such as red maple, sweet gum, and tulip poplar. The
feature being impacted by proposed impacts l -3_ was determined at the time of evaluation
and the DWQ site meeting to bean abandoned farm ditch: Both maps referred to above
have the scales provided and north arrows.
2. You requested we "submit a proposed impact map that identifies what the correct
impacts are (wetland, streams and/or buffers). These plans must show all built-
out structures and impervious cover. The plans must indicate all utilities and
easements."
The attached proposed impact map identifies the proposed impacts correctly (i.e. channel,,. -
wetland,, and buffer). Phase 3 of the Gardens does not currently contain structures;
utilities, etc so all of the impervious cover and house placements are proposed. Proposed':
easements are indicated on the map as well as the existing utility easement.
3 You requested that we "submit the drainage plans, these 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 be indicated and drawn -to scale."
- We included four (4) E-sized drawings in our original submittal that detailed the
stormwater management.: Impact maps, combined with the detailed stormwater'plans,
provided topographic and other location information. Scales, heights, calculations, and
other information were included in legends and in tables on the right side of each
stormwater drawing.Priest Craven (the project engineer) has provided us with additional
scaled <stormwater'information and drawings that° are attached:
4. You,asked'that we "submit impact maps at alegible scale (1"=50") of the
proposed' impactsincluding but not limited to the culvert's; dissipaters, fill, state
regulated buffers, excavating and flooding. These impact maps should include
the size of the culverts, the length of the culverts, the velocities coming out of the
culverts and the size of the dissipaters."
Our impact maps did not include culvert and flow rate information. We have corrected
this oversight and included-the relevant information in 'an, additional set of impact maps.
Our original impact maps were drawn at 1 "=40' and l"=60' scales (excluding the overall
impact map). The overall map is attached at a 1:60 scale. .
You requested that we "show provision for, aquatic -life passage for all
wetland/stream, _ cr`ossings."
The attached II x 17 sheet depicts the culvert crossing of Impact 6.
6. You requested that we "submit the complete detailed breakdown of the assumed
built-out,conditions. This should include all roads, sidewalks, footprints of
houses, decks, driveways and all proposed amenities to be constructed within the
project property boundaries."
The attached maps provide the impervious surface breakdown for each of the phases
including the proposed phase.
7. You noted that, since the proposed project "lies within a 303(d)-listed (impaired)
watershed, the stormwater management plan should be redesigned as extended
detention wetlands, bio-retention areas and ponds followed by forested filter
strips. The design specifications shall be in accordance with the DENR 1999
Stormwater BMP Manual. Please include plans, specifications, BMP worksheets,
and supporting calculations."
We are attaching additional BMP-related information, including separate worksheets.
However, the four (4) E-sized sheets included in our original submittal depict the
proposed "Extended Detention Wetlands" and the relevant number, and each sheet
includes hydrologic, flow, impervious; and other calculations in'tables along the right,
side of each page. Additional information for each of these areas is provided and the
corresponding DWQ "worksheets are attached:
8. Finally, you asked us to "submit an operation and maintenance agreement for the
stormwater management devices."
An operation and maintenance agreement is attached.
Please do not hesitate to contact us in the event that we have misinterpreted or
misunderstood your request for additional information.
Sincerely,
James Dasher Sean Clark

10. Describe the overall project in detail, including the type of equipment to be used: The
project is a single-family residential subdivision that includes impacts resulting from lot fill
and a road crossing stormwater management, a sewer line crossing, and a multi-purpose
path. Construction will involve standard grading and equipment. Heavy equipment typically
used for such projects will be employed on this site.
11. Explain the purpose of the proposed work: The project will provide single-family
residences to meet the growing demand for housing in the area. The resulting impacts are
required to provide necessary utilities (i.e., roads, sanitary sewer, etc.) to the project.
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.
On 11 September 2001 Mr. Charles Brown of NC DWQ determined the applicability of the
Neuse Buffer Rules to jurisdictional features on the subject property (NBRRO 01-259). A
feature at the northern property line starts approximately 25 feet inside the western property line
and terminates approximately 50 feet west of the utility easement that is present on site. This
feature becomes subject again at a point west of the utility easement and south of the proposed
road crossing. The other east-flowing stream on site enters the property in the southwest
property corner, and is buffered throughout its extent on site to its confluence with a UT to
Indian Branch. That UT to Indian Branch flows on site within 200 feet of the southeast property
corner, and is buffered throughout its extent on site. The USACE approved the wetland
delineation on 8 January 2002 (USACE Action ID #200220371) after reviewing, the fieldwork
conducted by S&EC. Earlier phases of the project are shown, and impacted 0.071 acres of
wetland. Because this area was below 0.10 acre and the project has not been completed,
notification to the USACE/NC DWQ has not previously been submitted to S&EC's knowledge.
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.
The applicant does not anticipate request additional permits related to construction on this
project.
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. The applicant must also
Page 3 of 9
provide justification for these impacts in Section VII below. All proposed impacts, permanent
and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must 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: Proposed impacts resulting
from lot fill include 109 feet of intermittent stream (Impact 1) and 0.118 acres of wetland
(Impact 3). Proposed impacts from excavation include 0.112 acres of temporary wetland

5. 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
Describe the method of construction (e.g., dam/embankment, excavation, installation of
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
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
Page 5 of 9
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The applicant has taken several steps to minimize impacts where they are unavoidable. Road
crossings have been re-engineered; others have been eliminated, and cul-de-sacs created in their
place in order to avoid crossing additional jurisdictional features present on the site. The main
road crossing (Impact 6) was shifted "upstream" so as to avoid the buffered area and to use an
existing crossing within the utility easement.
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 March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP 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/stnngide.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.
Impact 6 is a road crossing of a perennial stream that is within the utility line easement on
the property. Impacts in this area were minimized by utilizing an old crossing within the
access and by crossing upstream of where the channel becomes buffered. Although this
channel contains water most of the year it has been greatly impacted by the easement and
therefore is not considered "important/mitigatable". For this reason we do not believe that
stream mitigation should be required. All buffer impacts proposed are considered
Page 6 of 9
"allowable" or "exempt" and therefore no buffer mitigation is proposed. If the USACE
requires wetland mitigation, the applicant proposes payment to the NC EEP.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): 0
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): NA
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
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.
Yes ? No ?
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.
Page 7 of 9
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or. other (please identify, )?
Yes ® No ? If you answered "yes", provide the following information:
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.
Zone* Impact
(square feet) Multiplier Required
Mitigation
1 4,596 3 13,788
2 4,443 1.5 6,665
Total 20,453**
* Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
** All proposed activities resulting in impacts to the riparian buffers are considered "Allowable"
or "Exempt" by the buffer rules.
XI.
XII.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or.0260.
All proposed activities resulting in impacts to the riparian buffers are considered "Allowable" or
"Exempt" by the buffer rules.
Stormwater (required by DWQ)
Describe impervious acreage (both 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.
Impervious surface area on site equals 27.71% (i.e., less than 30%). For this reason, an NC
DWQ-approved stormwater plan is not required. Proposed stormwater devices are however,
shown on the attached stormwater management plan (4 sheets) and impact maps (5 sheets).
Sewage Disposal (required by DWQ)
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.
Wastewater will be handled in accordance with standard best management practices pertaining to
construction of this type.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 211.0500) or any Buffer Rules?
Yes ? No
Page 8 of 9
Is this an after-the-fact permit application?
Yes ? No
XIV. 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).

WETLAND DETENTION BASIN # 2 OPERATION AND MAINTENANCE AGREEMENT
THE GARDENS AT TOWNHALL COMMONS
The wetland detention basin system is defined as the Wetland Detention Basin #2, pretreatment including
forebays.
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wetland detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet wetland detention basin system semi-annually or when
depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be
disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact
water quality (i.e. stockpiling near a wetland detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 334.5 feet in the main pond, the sediment shall be removed.
[For stormwater wetlands: If the elevation of the marsh areas exceed the permanent pool elevation, the
sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of
soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations.
Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled
for more than two weeks.]
When the permanent pool depth reads 333.75 feet in the forebay [and micro-pool], the sediment shall be
removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
[For wetlands: Wetland planting densities in the marsh areas should be maintained by replanting bare
areas as needed. Wetland plants should be encouraged to grow in the marsh areas.]
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet [wetland] detention basin system shall be maintained in good working order.
8. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All
accumulated sediment and debris shall be removed from the structure, and a level elevation shall be
maintained across the entire flow spreading structure. Any down gradient erosion must be repaired and/or
replanted as necessary.

WETLAND DETENTION BASIN # 4 OPERATION AND MAINTENANCE AGREEMENT
THE GARDENS AT TOWNHALL COMMONS
The wetland detention basin system is defined as the Wetland Detention Basin #4, pretreatment including
forebays.
Maintenance activities shall be performed as follows:
After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wetland detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days as designed.
2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow
vegetative cover to maintain a maximum height of six inches, and remove trash as needed.
3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet wetland detention basin system semi-annually or when
depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be
disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact
water quality (i.e. stockpiling near a wetland detention basin or stream, etc.).
The measuring device used to determine the sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments.
When the permanent pool depth reads 340.25 feet in the main pond, the sediment shall be removed.
[For stormwater wetlands: If the elevation of the marsh areas exceed the permanent pool elevation, the
sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of
soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations.
Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled
for more than two weeks.]
When the permanent pool depth reads 339.75 feet in the forebay [and micro-pool], the sediment shall be
removed.

5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These
plants shall be encouraged to grow along the vegetated shelf and forebay berm.
[For wetlands: Wetland planting densities in the marsh areas should be maintained by replanting bare
areas as needed. Wetland plants should be encouraged to grow in the marsh areas.]
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment
through the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet [wetland] detention basin system shall be maintained in good working order.
8. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All
accumulated sediment and debris shall be removed from the structure, and a level elevation shall be
maintained across the entire flow spreading structure. Any down gradient erosion must be repaired and/or
replanted as necessary.

RE: Nationwide Permit 39, 401-Water Quality Certification and Buffer Compliance
The Gardens at Town Hall Commons
Morrisville, Wake County, North Carolina
Dear Ms. Burdette and Ms. Edwards:
On behalf of Centex Homes, Inc., we hereby request authorization from the US Army
Corps of Engineers (USACE) to use Nationwide Permit (NWP) 39 for proposed
permanent impacts to an intermittent stream and jurisdictional wetlands resulting from
the construction of a single-family residential. subdivision. Written concurrence is
requested from the North Carolina Division of Water Quality that states that the project
complies with the Neuse Buffer Rules and GC3374. A Pre-construction Notification
Application (PCN) is attached, which includes an Agent Authorization Form.
Site Location
The site is approximately 50 acres in size. The subject property is located approximately
4,000 feet southwest of the intersection of NC Hwy 54 and McCrimmon Parkway (SR
1635). There is a small extension road connecting the site to McCrimmon Parkway.
Please refer to the attached Figures 1 and 2 for the project's location on a USGS
topographic quadrangle and the Wake County Soil Survey maps, respectively.
Project Description
The project is a single-family residential subdivision includes impacts resulting from lot
fill and a road crossing, and proposed impacts to jurisdictional wetlands resulting from lot
fill, stormwater management, a sewer line crossing, and a multi-purpose path; proposed
impacts to a perennial stream resulting from a road crossing; and buffer impacts resulting
from stormwater management construction. Proposed impacts are described in the

attached PCN and detailed on the attached Wetland Impact Maps. Proposed impacts
resulting from lot fill include 109 feet of intermittent stream (Impact 1) and 0.118 acres
of wetland (Impact 3).- Proposed impacts from excavation,, include 0.112 acres of
temporary wetland impacts (Impact 4), 0.089 acres of permanent wetland impact (Impact
5), and 110 feet of perennial stream impacts (Impact 6). Proposed impacts resulting from
a greenway path include 0.054 acres (Impact 9) and 67 feet of intermittent stream impacts
(Impact 2). In addition, proposed impacts to Zone 1 of the Neuse Buffer total 4,596
square feet, and proposed impacts to Zone 2 of the Neuse Buffer total 3,903 square feet.
Proposed impacts total 286 linear feet of intermittent stream channel, 0.374 acres of
wetland, and 9,039 square feet of riparian buffer. Previous impacts on the project
total 0.07 acres of wetland due to fill and no impacts to streams or buffers.
Impervious surface area on site equals 27.71% (i.e., less than 30%). For this reason, an
NC DWQ-approved stormwater plan is not required. Proposed stormwater devices are, ,
however, shown on the attached stormwater management plan (4 sheets) and impact
maps (5 .sheets). All impacts resulting from the installation of extended detention
wetlands were necessary to provide stormwater control for the property.
Mitigation
Impact 6 proposes a road crossing over perennial stream -that is within the utility line
easement. The location of this road crossing was chosen because it avoids the riparian
buffers and crosses at a point that has been used as a crossing for the utility line
maintenance. Although this drainage is probably perennial (i.e. contains water most of
the year), it has been heavily impacted by the utility easement and is therefore not
"important/mitigatable." For this reason no stream mitigation should be required by the
USACE. Because impacts to perennial streams total less than 150 linear feet for the
project no stream mitigation will be required by the NC-DWQ. All buffer impacts
proposed are considered "allowable" or "exempt" and therefore no buffer mitigation is
proposed. If the USACE requires wetland mitigation, the applicant proposes payment to
the NC EEP.
Sincerely,
Sean Clark

list and describe permits issued for prior segments of the same T.I.P. project, along with
construction schedules.
On 11 September 2001, Mr. Charles Brown of NC DWQ determined the applicability of the
Neuse Buffer Rules to jurisdictional features on the subject property (NBRRO 01-259). A
feature at the northern property line starts approximately 25 feet inside the western property line
and terminates approximately 50 feet west of the utility easement that is present on site. This
feature becomes subject again at a point west of the utility easement and south of the proposed
road crossing. The other east-flowing stream on site enters the property in the southwest
property corner, and is buffered throughout its extent on site to its confluence with a UT to
y
Indian Branch That UT to Indian Branch flows on site within 200 feet of the southeast p=ert
corner, and is buffered throughout its extent on site. The USACE approved the wetland
delineation on 8 January 2002 (USACE Action ID #200220371) after reviewing the fieldwork
conducted by S&EC Earlier phases of the project are shown and impacted 0.071 acres of
wetland Because this area was below 0.10 acre and the project has not been completed,
notification to the USACE/NC DWQ has not previously been submitted to S&EC's knowledge.

and temporary, must be listed herein, and must be clearly identifiable on an accompanying site
plan. All wetlands and waters, and all streams (intermittent and perennial) must 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: Proposed impacts resulting
from lot fill include 109 feet of intermittent stream (Impact 1) and 0 118 acres of wetland

Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond,
local stormwater requirement, etc.): 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
Page 5 of 9
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The applicant has taken several steps to minimize impacts where they are unavoidable Road
crossings have been re-engineered, others have been eliminated, and cul-de-sacs created in their
place in order to avoid crossing additional jurisdictional features present on the site The main
road crossing (Impact 6) was shifted "upstream" so as to avoid the buffered area and to use an
existing crossing within the utility easement
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 March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP 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
hLtp://h2o.enr.state.nc.us/ncwetlands/stringide.htrnl.
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.
Impact 6 is a road crossing of a perennial stream that is within the utility line easement on
the property. Impacts in this area were minimized by utilizing an old crossing within the
access and by crossing upstream of where the channel becomes buffered Although this
channel contains water most of the year it has been greatly impacted by the easement and
therefore is not considered "important/mitigatable". For this reason we do not believe that
stream mitigation should be required All buffer impacts proposed are considered
Page 6 of 9
"allowable" or "exempt" and therefore no buffer mitigation is proposed. If the USACE
requires wetland mitigation the applicant proposes payment to the NC EEP.
2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
[phone] to determine availability and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at hqp://h2o.enr.state.nc.us/wip/index.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): 0
Amount of buffer mitigation requested (square feet): 0
Amount of Riparian wetland mitigation requested (acres): 0
Amount of Non-riparian wetland mitigation requested (acres): 0
Amount of Coastal wetland mitigation requested (acres): NA
IX. Environmental Documentation (required by DWQ)
Does the project involve an expenditure of public (federal/state) funds or the use of public
(federal/state) land?
Yes ? No
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.
Yes ? No ?
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.
Page 7 of 9
Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 2B .0250 (Randleman Rules and
Water Supply Buffer Requirements), or other (please identify, )?
Yes ® No ? If you answered "yes", provide the following information:
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.
Zone* Impact
(square feet Multiplier Required
Mitigation
1 4,596 3 13,788
2 4,443 1.5 6,665
Total 20,453**
Lone t extends out 3u teet perpendicular from near bank of channel; Zone 2 extends an
additional 20 feet from the edge of Zone 1.
** All proposed activities resulting in impacts to the riparian buffers are considered "Allowable"
or "Exempt" by the buffer rules.
If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation
of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or
Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as
identified within 15A NCAC 2B .0242 or. 0260.
All proposed activities resulting in impacts to the riparian buffers are considered "Allowable" or
"Exempt" by the buffer rules.
XI. Stormwater (required by DWQ)
Describe impervious acreage (both 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.
Impervious surface area on site equals 27.71% (i.e., less than 30%) For this reason an NC
DWQ-approved stormwater plan is not required Proposed stormwater devices are however,
shown on the attached stormwater management plan (4 sheets) and impact maps (5 sheets)
XII. Sewage Disposal (required by DWQ)
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.
Wastewater will be handled in accordance with standard best management practices pertaining to
construction of this We.
XIII. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules?
Yes ? No
Page 8 of 9
Is this an after-the-fact permit application?
Yes ? No
XIV. 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).
