APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Conditions,
Dear Mr. Huff:
You have our approval, in accordance with the attached conditions, to place fill in 0.265 acre of wetlands and to impact
7,677 square feet of protected Neuse Buffers in order to construct the Autumn Park PUD in Wake County, as described in
your application received by the Division of Water Quality on August 8, 2002, and in additional correspondence received
August 27, 2002. After reviewing your application, we have determined that this fill is covered by General Water Quality
Certification Number 3362, which can be downloaded from our web site at http://h2o.enr.state.nc.us/ncwetlands . This
Certification allows you to use Nationwide Permit Number 39 when issued by the U.S. Army Corps of Engineers. This
approval is also valid for the Neuse River Buffer Rules (15A NCAC 2B .0233). In addition, you should get any other federal,
state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control, .
Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 permit
expires unless otherwise specified in the General Certification. This Certification replaces the one issued to you on
October 3, 2002.
This approval is only valid for the purpose and design that you described in your application. If you change your:.
project, you must notify us in writing and you may be required to send us a new applicatior)-for a new certification. ?._If the
property is sold, the new owner must be given a copy of the Certification and approval letter ands is thereby responsible for
complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid; you must follow. the.
conditions listed in the attached certification as well as the additional conditions listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or
areas within 50 feet of all streams and ponds. The deed notifications for Lots 46 and 47 shall include building envelopes
with respect to the protected Neuse Buffers. These mechanisms shall be put in place within 30 days of the date of this
letter or the issuance of the 404 Permit (whichever is later). A sample deed notification format can be downloaded from
the 401Mletlands Unit web site at http://h2o.enr.state.nc.us/ncwetiands;
2. The stormwater managment facilities including the grassed swales, level spreaders and pocket wetland indicated in the
plans received by this Office on February 11 and 12, 2003 (and ammended February 25, 2003), and as approved by this
Office, shall be constructed and operational, and the stormwater management plan (as approved by this Office) shall be
implemented before any permanent building is occupied in the draiange area served by those facilities. The structural
stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No ,
changes to the structural stormwater practices shall be made without written authorization from the Division of Water
Quality. However, the sediment basin located on lot 47 must be removed from Zone 1 of the buffer and the permanent
level spreader must be located outside of Zone 2;
3. An additional condition is that stormwater shall be directed to flow in a diffuse manner at non-erosive velocities through
the entire protected stream buffers without re-concentrating. Stormwater at Lots 46 and 47 shall be designed to flow in
a diffuse manner through the entire buffer area, and may not enter the buffers in a concentrated form;
4. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401
Certification has been completed.

POCKET WETLAND OPERATION AND MAINTENANCE AGREEMENT
for
Autumn Park Townhomes
Holly Springs, North Carolina
The pocket wetland system is defined as the wetland detention basin, pretreatment including
micropools and the vegetated filter if one is provided.
Maintenance activities shall be performed as follows:
1. After every significant runoff producing rainfall event and at least monthly:
a. Inspect the pocket wetland 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. 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. 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 pocket wetland system or stream, etc.).
5. 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 pocket wetland 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.

Calculation of Runoff Volume required for storage
The runoff to the pond for the 1" storm detention requirement is calculated using the SCS curve
number method. Impervious areas that directly enter the pond are counted as Directly Connected
Impervious Areas (DCIAs). No infiltration calculation will be provided for these areas. Areas
not directly connected will be accounted for in a composite curve number.
From SCS Soils Survey map, predominant hydrologic soil type = D
a
Using basic SCS runoff methodology, with no adjustments made
to initial abstractions (0.2*S and 0.8*S).
Impervious Area, directly connected (DCIA) = 1.39 acres
@CN= 98
Other areas draining to pond (not DCIA) = 1.96 acres
@CN= 61
Runoff from DCIAs =_>
Precipitation amount = 1.0 inches
S = 0.204 inches (calculated)
Q* = 0.791 inches (calculated)
Runoff volume = 3991 CF
Runoff from non-connected areas =_>
Precipitation amount = 1.0 inches
S = 6.393 inches (calculated)
Q* = 0.000 inches (calculated)
Runoff volume = 0 CF
Therefore, total runoff from precipitation in question = 3991 CF
This amount of runoff must be stored in the pond above normal pool elevation,
and be released in a period of two (2) to five (5) days, by an inverted PVC
siphon, the invert end of which is set at permanent pool elevation.
e
Pocket Wetland

Calculation of depth required for runoff storage pool (above normal pool)
Normal pool depth (above invert) = 0.00 feet
Storage provided at permanent pool depth = 0 CF (calculated)
Total storage required for normal + storage pool = 3991 CF
Stage (above invert) associated with this storage = 1.21 feet
Therefore, depth required above normal pool for storm storage = 1.21 feet
14.51 inches
Therefore set crest of principal spillway at stage = 1.21 feet
and EL = 440.71 feet
At principal spillway crest, storm pool storage provided = 3993 CF

Re: Major Amendment for 401 Water Quality Certification for Autumn Park PUD
Holly Springs, Wake County
DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
This letter is in response to a recent telephone conversation with you, during which we discussed
steps required for removal of additional condition #2 from the "Approval of 401 Water Quality
Certification and Neuse River Buffer Rules with Additional Conditions", for Autumn Park
Subdivision in Holly Springs (Wake County), dated October 3, 2002. You stated that removal of
additional condition #2 constitutes a Major Amendment to the existing 401 Certification.
The Owner requests that you accept this letter as a formal request for a Major Amendment to the
existing approved 401 Certification as detailed above. As required, a check for the DWQ review
fee in the amount of $200 is attached.
You requested that level spreader locations and sizes be resubmitted with this request for a Major
Amendment. A copy of the "Autumn Park Subdivision - Storm Drainage and Erosion Control
Plan" and the "Autumn Park Phase 3: Townhomes - Drainage, Grading and Erosion Control
Plan" are attached for your reference. These two plans illustrate the location and size of each
planned level spreader as well as calculated stormwater flows entering each.
Thank you in advance for your time spent reviewing this request. Please do not hesitate to call
me if you have any questions, comments or concerns about this request or if you require
additional information to process this request.
Sincerely,
Scott Mitchell, PE, LSS

APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Conditions,
Dear Mr. Huff:
You have our approval, in accordance with the attached conditions, to place fill in 0.265 acre of wetlands and to impact
7,677 square feet of protected Neuse Buffers in order to construct the Autumn Park PUD in Wake County, as described in
your application received by the Division of Water Quality on August 8, 2002, and in additional correspondence received
August 27, 2002. After reviewing your application, we have determined that this fill is covered by General Water Quality
Certification Number 3362, which can be downloaded from our web site at hftp://h2o.enr.state.nc.us/ncwetlands. This
Certification allows you to use Nationwide Permit Number 39 when issued by the U.S. Army Corps of Engineers. This
approval is also valid for the Neuse River Buffer Rules (15A NCAC 2B .0233). In addition, you should get any other federal,
state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us in writing and you may be required to send us a new application for a new certification. If the
property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for
complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the
conditions listed in the attached certification as well as the additional conditions listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or
areas within 50 feet of all streams and ponds. The deed notifications for Lots 46 and 47 shall include building envelopes
with respect to the protected Neuse Buffers. These mechanisms shall be put in place within 30 days of the date of this
letter or the issuance of the 404 Permit (whichever is later). A sample deed notification format can be downloaded from
the 401/Wetlands Unit web site at http•//h2o.enr.state.nc.us/ncwetlands ;
2. An additional condition is that a final, written stormwater management plan shall be approved in writing by this Office
before the impacts specified in this Certification occur per Condition No. 3 in General Certification No. 3362. The
stormwater management plan must include plans and specifications for stormwater management facilities that are
appropriate for surface waters classified as Class B NSW and designed to remove 85% TSS according to the most
recent version of the NC DENR Stormwater Best Management Practices Manual. These facilities must be designed to
treat the runoff from the entire project, unless otherwise explicitly approved by the Division of Water Quality. Also, before
any permanent building is occupied at the subject site, the facilities (as approved by this Office) shall be constructed and
operational, and the stormwater management plan (as approved by this Office) shall be implemented. The structural
stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No
changes to the structural stormwater practices shall be made without written authorization from the Division of Water
Quality.
3. An additional condition is that stormwater shall be directed to flow in a diffuse manner at non-erosive velocities through
the entire protected stream buffers without re-concentrating. Stormwater at Lots 46 and 47 shall be designed to flow in
a diffuse manner through the entire buffer area, and may not enter the buffers in a concentrated form;
4. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401
Certification has been completed.

Re: 401 Water Quality Certification for Autumn Park PUD
Holly Springs, Wake County
DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
Spaulding & Norris recently received a copy of the "Approval of 401 Water Quality Certification
and Neuse Buffer Rules with Additional Conditions" for Autumn Park PUD in Holly Springs
(Wake County), dated October 3, 2002. After a review of the standard Conditions of Certification
for WQC #3362, particularly standard Condition of Certification #3, the Owner intends to reduce
the project's total impervious surface to less than 30 percent. We understand that if the project
will have less than 30 percent impervious coverage at completion, additional condition #2 per the
October 3, 2002, 401 Water Quality Certification will no longer be required. The reduction in
impervious coverage will be achieved by slightly reducing the average home size and by
constructing homes closer to the front yard setback than was originally planned for this
development. This change in home placement will reduce the length of all driveways by
approximately 10 feet. These measures alone reduce the total impervious coverage for this
project to less than 30 percent. Additionally, the Owner is currently seeking approval from the
Town of Holly Springs to change the proposed greenway from an impervious asphalt surface to a
pervious surface material (mulch, wood chips, gravel, etc.) which would further reduce the total
imperious surface area for this project. Supporting calculations are attached to this
correspondence for your review.
The Owner requests that this letter be accepted as a formal request that DWQ abrogate additional
condition 42 of the "Approval of 401 Water Quality Certification and Neuse Buffer Rules with
Additional Conditions" for Autumn Park PUD, dated October 3, 2002. Thank you in advance for
your time spent reviewing this request. Please do not hesitate to call me if you have any
questions, comments or concerns about this request.

Re: Major Amendment for 401 Water Quality Certification for Autumn Park PUD
Holly Springs, Wake County
DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
On January 17, 2003, we had a telephone conversation about Autumn Park PUD (Holly Springs,
Wake County) and the need for further evidence of the proposed reduction in impervious surface
area. This letter is in response to your request for additional information to substantiate the
impervious coverage will be less than 30% for this project.
The original PCN Application for this project was submitted on August 8, 2002. Attached to the
PCN is a plan sheet titled "Autumn Park Subdivision - Wetlands Impact Analysis (C-22)". On
the top, right corner of this plan, a table titled "Project Data" lists various detailed information
about the project. This table lists the project total acreage as 49.468 acres. This project acreage
was entered as the total acreage of the site in Section XI of the PCN Application. What I failed to
notice about this table when preparing the PCN Application, was that it only accounts for the
single-family home portion of the project. Hence, the townhome portion of the project is not
included in the listed total acreage in the "Project Data" table. The actual total acreage of the site,
57.755 acres, is accurately listed on the wetlands survey supplied by Mrs. Amanda Jones of the
US Army Corps of Engineers, Raleigh Regulatory Field Office. This wetland survey supplied by
Mrs. Jones was also included with the August 8, 2002, PCN Application. This error on my part
accounted for a reported total site area that was 8.287 acres (17%) less than the actual site area. If
the correct total site acreage had been reported in Section XI of the PCN Application, the initial
proposed impervious area would equate to 36.7% (21.2 acres impervious / 57.755 acres total x
100) versus the reported 42.9%.
I submitted a letter to you dated November 20, 2002, in which I explain the methods used to
reduce the total proposed impervious acreage for this project. As stated in this letter, the
reduction in proposed impervious area will be achieved by slightly reducing the average home
size and by constructing homes closer to the front yard setback than was originally planned for
this development. The effect of placing the homes closer to the front yard setback is that
driveway length is reduced. Please understand that the Owner of this project has control over
what floor plans are available to future homeowners as well as their placement on this site.
Through these mechanisms, the Owner has committed to a maximum average impervious area
per single family home lot of 1,900 ft and 1,500 f 2 per townhome unit. These self-imposed
limitations on impervious area require that the Owner sell a smaller average product. However,
the Owner has chosen this reduction in total impervious surface area over the installation of
Phone: [phone] • Fax: [phone] •972 Trinity Road • Raleigh, North Carolina 27607
c`
several BMPs on the site. The calculations provided with the letter dated November 20, 2002,
indicate a 3.96 acre reduction in total proposed impervious area when compared to the 21.2 acres
of proposed impervious surface listed in Section XI of the August 8, 2002, PCN Application.
Since there are 194 single family units and 50 townhome units planned for this project, this
equates to an average reduction of 707 fl2 of impervious surface area per unit. While this does
equate to a substantial reduction in desired average home size, it still allows for a product that is
very comparable to several other subdivisions and townhome developments in the Holly Springs
area.
The DWQ letter dated January 15, 2003, requesting additional information states that "the plan
approved along with the 401 Water Quality Certification, issued October 3, 2002, appear to be
essentially the same plans as those submitted December 23, 2002." Please note that the plans
submitted on both dates do not indicate building footprints or driveways for the single family
home portion of the project, hence there is no reason for the plans to have changed. Also please
note that there is no mention in any correspondence of altering streets, sidewalks or greenway
locations in order to achieve the desired reduction in impervious area for this project. The
previously proposed reduction in impervious area relied solely on the reduction of building and
driveway footprints.
The November 20, 2002, letter I submitted to you mentioned that the Owner was in the process of
requesting permission from the Town of Holly Springs to change the proposed greenway from an
impervious surface material to a pervious material (mulch, wood chips, gravel, etc.). Since the
date of this letter, the Owner has received verbal approval to change the proposed greenway trails
to mulch instead of asphalt. This change reduces the total impervious surface for the project by
another 17,149 W. A revised impervious surface calculation sheet is provided for your reference.
After changing the greenway to mulch, the total proposed impervious surface is reduced to
733,667 W. This equates to an impervious surface coverage of 29.2%.
I trust that these explanations and calculations will provide the requested additional substantiating
information to prove that the project's total impervious surface will in fact be less than 30% at
completion. Thank you in advance for your time spent reviewing this request. Please call me if
you have any questions, comments or concerns about this request or if you require additional
information to process this request.

APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Conditions,
Dear Mr. Huff:
You have our approval, in accordance with the attached conditions, to place fill in 0.265 acre of wetlands and to impact
7,677 square feet of protected Neuse Buffers in order to construct the Autumn Park PUD in Wake County, as described in
your application received by the Division of Water Quality on August 8, 2002, and in additional correspondence received
August 27, 2002. After reviewing your application, we have determined that this fill is covered by General Water Quality
Certification Number 3362, which can be downloaded from our web site at http://h2o.enr-state.nc.us/ncwetlands. This
Certification allows you to use Nationwide Permit Number 39 when issued by the U.S. Army Corps of Engineers. This
approval is also valid for the Neuse River Buffer Rules (15A NCAC 2B .0233). In addition, you should get any other federal,
state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us in writing and you may be required to send us a new application for a new certification. If the
property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for
complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the
conditions listed in the attached certification as well as the additional conditions listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or
areas within 50 feet of all streams and ponds. The deed notifications for Lots 46 and 47 shall include building envelopes
with respect to the protected Neuse Buffers. These mechanisms shall be put in place within 30 days of the date of this
letter or the issuance of the 404 Permit (whichever is later). A sample deed notification format can be downloaded from
the 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands ;
2. An additional condition is that a final, written stormwater management plan shall be approved in writing by this Office
before the impacts specified in this Certification occur per Condition No. 3 in General Certification No. 3362. The
stormwater management plan must include plans and specifications for stormwater management facilities that are
appropriate for surface waters classified as Class B NSW and designed to remove 85% TSS according to the most
recent version of the NC DENR Stormwater Best Management Practices Manual. These facilities must be designed to
treat the runoff from the entire project, unless otherwise explicitly approved by the Division of Water Quality. Also, before
any permanent building is occupied at the subject site, the facilities (as approved by this Office) shall be constructed and
operational, and the stormwater management plan (as approved by this Office) shall be implemented. The structural
stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No
changes to the structural stormwater practices shall be made without written authorization from the Division of Water
Quality.
3. An additional condition is that stormwater shall be directed to flow in a diffuse manner at non-erosive velocities through
the entire protected stream buffers without re-concentrating. Stormwater at Lots 46 and 47 shall be designed to flow in
a diffuse manner through the entire buffer area, and may not enter the buffers in a concentrated form;
4. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401
Certification has been completed.

DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
Spaulding & Norris recently received a copy of the "Approval of 401 Water Quality Certification
and Neuse Buffer Rules with Additional Conditions" for Autumn Park PUD in Holly Springs
(Wake County), dated October 3, 2002. After a review of the standard Conditions of Certification
for WQC #3362, particularly standard Condition of Certification #3, the Owner intends to reduce
the project's total impervious surface to less than 30 percent. We understand that if the project
will have less than 30 percent impervious coverage at completion, additional condition #2 per the
October 3, 2002, 401 Water Quality Certification will no longer be required. The reduction in
impervious coverage will be achieved by slightly reducing the average home size and by
constructing homes closer to the front yard setback than was originally planned for this
development. This change in home placement will reduce the length of all driveways by
approximately 10 feet. These measures alone reduce the total impervious coverage for this
project to less than 30 percent. Additionally, the Owner is currently seeking approval from the
Town of Holly Springs to change the proposed greenway from an impervious asphalt surface to a
pervious surface material (mulch, wood chips, gravel, etc.) which would further reduce the total
imperious surface area for this project. Supporting calculations are attached to this
correspondence for your review.
The Owner requests that this letter be accepted as a formal request that DWQ abrogate additional
condition #2 of the "Approval of 401 Water Quality Certification and Neuse Buffer Rules with
Additional Conditions" for Autumn Park PUD, dated October 3, 2002. Thank you in advance for
your time spent reviewing this request. Please do not hesitate to call me if you have any
questions, comments or concerns about this request.

The site plan appears to be virtually unchanged from the one that we approved for the project
that claimed 42% imperviousness. It is not clear how the impervious coverage will be reduced to
29.8%. Additionally, I do not anticipate that condition 3 of the WQC requiring diffuse flow shall be met
based on the information provided. I recommend that we put the project on hold.

Re: Major Amendment for 401 Water Quality Certification for Autumn Park PUD
Holly Springs, Wake County
DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
This letter is in response to a recent telephone conversation with you, during which we discussed
steps required for removal of additional condition #2 from the "Approval of 401 Water Quality
Certification and Neuse River Buffer Rules with Additional Conditions", for Autumn Park
Subdivision in Holly Springs (Wake County), dated October 3, 2002. You stated that removal of
additional condition #2 constitutes a Major Amendment to the existing 401 Certification.
The Owner requests that you accept this letter as a formal request for a Major Amendment to the
existing approved 401 Certification as detailed above. As required, a check for the DWQ review
fee in the amount of $200 is attached.
You requested that level spreader locations and sizes be resubmitted with this request for a Major
Amendment. A copy of the "Autumn Park Subdivision - Storm Drainage and Erosion Control
Plan" and the "Autumn Park Phase 3: Townhomes - Drainage, Grading and Erosion Control
Plan" are attached for your reference. These two plans illustrate the location and size of each
planned level spreader as well as calculated stormwater flows entering each.
Thank you in advance for your time spent reviewing this request. Please do not hesitate to call
me if you have any questions, comments or concerns about this request or if you require
additional information to process this request.

APPROVAL of 401 Water Quality Certification and Neuse River Buffer Rules with Additional Conditions,
Dear Mr. Huff:
You have our approval, in accordance with the attached conditions, to place fill in 0.265 acre of wetlands and to impact
7,677 square feet of protected Neuse Buffers in order to construct the Autumn Park PUD in Wake County, as described in
your application received by the Division of Water Quality on August 8, 2002, and in additional correspondence received
August 27, 2002. After reviewing your application, we have determined that this fill is covered by General Water Quality
Certification Number 3362, which can be downloaded from our web site at httr)://h2o.enr.state.nc.us/ncwetlands . This
Certification allows you to use Nationwide Permit Number 39 when issued by the U.S. Army Corps of Engineers. This
approval is also valid for the Neuse River Buffer Rules (15A NCAC 213.0233). In addition, you should get any other federal,
state or local permits before you go ahead with your project including (but not limited to) Sediment and Erosion Control,
Non-Discharge and Water Supply Watershed regulations. Also this approval will expire when the accompanying 404 permit
expires unless otherwise specified in the General Certification.
This approval is only valid for the purpose and design that you described in your application. If you change your
project, you must notify us in writing and you may be required to send us a new application for a new certification. If the
property is sold, the new owner must be given a copy of the Certification and approval letter and is thereby responsible for
complying with all conditions. If total wetland fills for this project (now or in the future) exceed one acre, compensatory
mitigation may be required as described in 15A NCAC 2H .0506 (h). For this approval to be valid, you must follow the
conditions listed in the attached certification as well as the additional conditions listed below:
1. Deed notifications or similar mechanisms shall be placed on all lots with remaining jurisdictional wetlands and waters or
areas within 50 feet of ail streams and ponds. The deed notifications for Lots 46 and 47 shall include building envelopes
with respect to the protected Neuse Buffers. These mechanisms shall be put in place within 30 days of the date of this
letter or the issuance of the 404 Permit (whichever is later). A sample deed notification format can be downloaded from
the 401Metlands Unit web site at http://h2o.enr.state.nc.us/ncwetiands ;
2. An additional condition is that a final, written stormwater management plan shall be approved in writing by this Office
before the impacts specified in this Certification occur per Condition No. 3 in General Certification No. 3362. The
stormwater management plan must include plans and specifications for stormwater management facilities that are
appropriate for surface waters classified as Class B NSW and designed to remove 85% TSS according to the most
recent version of the NC DENR Stormwater Best Management Practices Manual. These facilities must be designed to
treat the runoff from the entire project, unless otherwise explicitly approved by the Division of Water Quality. Also, before
any permanent building is occupied at the subject site, the facilities (as approved by this Office) shall be constructed and
operational, and the stormwater management plan (as approved by this Office) shall be implemented. The structural
stormwater practices as approved by this Office as well as drainage patterns must be maintained in perpetuity. No
changes to the structural stormwater practices shall be made without written authorization from the Division of Water
Quality.
3. An additional condition is that stormwater shall be directed to flow in a diffuse manner at non-erosive velocities through
the entire protected stream buffers without re-concentrating. Stormwater at Lots 46 and 47 shall be designed to flow in
a diffuse manner through the entire buffer area, and may not enter the buffers in a concentrated form;
4. You are required to return the attached Certification of Completion form to notify DWQ when all work included in the 401
Certification has been completed.

Re: 401 Water Quality Certification for Autumn Park PUD
Holly Springs, Wake County
DWQ # 02-1271
S&N Project # 308-01
Dear Mr. St. John,
Spaulding & Norris recently received a copy of the "Approval of 401 Water Quality Certification
and Neuse Buffer Rules with Additional Conditions" for Autumn Park PUD in Holly Springs
(Wake County), dated October 3, 2002. After a review of the standard Conditions of Certification
for WQC #3362, particularly standard Condition of Certification #3, the Owner intends to reduce
the project's total impervious surface to less than 30 percent. We understand that if the project
will have less than 30 percent impervious coverage at completion, additional condition #2 per the
October 3, 2002, 401 Water Quality Certification will no longer be required. The reduction in
impervious coverage will be achieved by slightly reducing the average home size and by
constructing homes closer to the front yard setback than was originally planned for this
development. This change in home placement will reduce the length of all driveways by
approximately 10 feet. These measures alone reduce the total impervious coverage for this
project to less than 30 percent. Additionally, the Owner is currently seeking approval from the
Town of Holly Springs to change the proposed greenway from an impervious asphalt surface to a
pervious surface material (mulch, wood chips, gravel, etc.) which would further reduce the total
imperious surface area for this project. Supporting calculations are attached to this
correspondence for your review.
The Owner requests that this letter be accepted as a formal request that DWQ abrogate additional

Re:
Additional Information for Autumn Park PUD - Holly
DWQ # 02-12-71
NBRRO 02-161
Dear Mr. Dorney,
I recently received your letter dated August 21, 2002, requesting additional information
for the Autumn Park PUD project in Holly Springs. The purpose of this letter is to
provide you with the requested additional information about the project in order to
facilitate DWQ's review of the PCN application submitted to you on August 8, 2002.
Five maps are included with this letter. As shown on the previously submitted "Wetlands
Impact Analysis" map, the project is separated into a single-family home section and a
townhome section. Separate construction drawings were produced for each of these
sections, hence, two plan sheets labeled "C-4" are included with this letter. Included
maps are identified as:
C-22: Autumn Park Subdivision - Wetlands Impact Analysis
(this is the same plan that is included with the PCN Application)
EX-1: Autumn Park PUD - Wetlands, Stream & Neuse Buffer Delineation
C-3: Autumn Park Subdivision - Utility Plan
C-4: Autumn Park Subdivision - Storm Drainage & Erosion Control Plan
C-4: Autumn Park: Phase 3: Townhomes -
Grading, Drainage & Erosion Control Plan
The plan titled "EX-1: Autumn Park PUD - Wetlands, Stream & Neuse Buffer
Delineation" shows all wetlands, streams, ponds & Neuse Buffers present on the property
at a scale of 1"=100'. This map shows the exact same features as indicated on the plan
titled "C-22: Autumn Park Subdivision - Wetlands Impact Analysis". The Wake County
Soils Map indicates a stream connecting the pond near the middle of the property to the
pond on the southern border of the property. This feature was investigated by Spaulding
& Norris and found to be non-existent. Subsequently, a field concurrence meeting was
held with Ms. Deborah Edwards of the DWQ Raleigh Regional Office. During this
meeting, Ms. Edwards agreed that this mapped feature was in fact non-existent and ruled
Phone: [phone] ? Fax: [phone] ? 972 Trinity Road • Raleigh, North Carolina 27607
that this area and the pond near the center of the property was not subject to the Neuse
River Basin Buffer Rules. A copy of Ms. Edwards' letter to this effect is attached for
your reference. The off-site subject feature behind lots 46 & 47 was delineated by
Spaulding & Norris, but was not visited during the on-site concurrence meeting with Ms.
Edwards. Clearly, Spaulding & Norris does not contend this feature's existence or
subjectivity to the Neuse River Basin Buffer Rules. All Neuse Buffers on this property
are accurately indicated on the "Wetlands, Stream & Neuse Buffer Delineation" map.
The stormwater plan for the property is shown on the attached plan sheets titled "C-4:
Autumn Park Subdivision - Storm Drainage & Erosion Control Plan" and "C-4: Autumn
Park: Phase 3: Townhomes - Grading, Drainage & Erosion Control Plan". Locations of
all proposed level spreaders are indicated on the included plans. Diffuse flow will be
established at the exit point of all critical stormwater collection systems through the use
of level spreaders as indicated.
Your letter implies that a sewer easement is proposed behind lots 46 & 47, creating an
unnecessary disturbance in Zone 1 of the Neuse Buffer in that location. I believe that the
20-foot Semi-Opaque Landscape Buffer that surrounds this portion of the property was
misinterpreted as a sanitary sewer easement. The Town of Holly Springs has required
this landscape buffer in this area, further assuring the maintenance of the Neuse Buffer
behind lots 46 & 47. A copy of plan "C-3: Autumn Park Subdivision - Utility Plan" is
included with this letter to more clearly indicate how these lots are to be served and to
lend further assurance that no sanitary sewer easement is planned behind these lots. No
disturbance is proposed for Zone 1 of the Neuse Buffer in this location. However, as
stated in the PCN Application cover letter, some grading & revegetation, within Zone 2
only, is proposed on lots 46 & 47.
Again, thank you for your time spent reviewing this permit application. I hope that this
response to your request for additional information clarifies any questions or eases any
concerns you may have had about this project. Please do not hesitate to contact me if you
have further questions, comments or concerns about this application.
Sincerely,
Scott Mitchell

Dear Mr. Huff:
On August 8, 2002 the Division of Water Quality (DWQ) was notified by receipt of your
application regarding your plan to fill wetland for the purpose of the Autumn Park PUD in Wake
County. Approval from DWQ is required to disturb these areas. Please provide seven copies of the
following information and refer to the DWQ# listed above in your reply. In particular as described in
15A NCAC 2B .0502, we will require you to locate all streams and ponds on the property. Please
show these on maps of suitable scale (for instance 1" = 100 feet) so we can begin to determine your
projects' compliance with 15A NCAC 2H .0500.
-1. The stormwater plan must show diffuse flow through the buffers.
2. Lots 46 & 47 show impacts in Zone 1 with sewer easement encroachment. Please provide
information as to why these can't be avoided or redesigned to avoid these impacts.
Please telephone me at 919-733-1786 if you have any questions or would require copies of
our rules or procedural materials. This project will remain on hold as incomplete in accordance with
15A NCAC 2H .0505(c). The processing time for this application will begin when this information is
received. If we do not hear from you by writing within three (3) weeks we will assume you no longer
want to pursue the project and will consider it withdrawn.

Dear Mr. Conoly:
Neuse River Basin Buffer Rules
NBRRO 02-161
Autumn Park
Holly Springs, Wake County, NC
On June 27, 2002, I conducted a site visit of feature A involved in the above referenced
project as identified on the attached maps. It was determined that feature A shown on the Wake
County Soil Survey and on the USGS Apex, NC Quad map could potentially be subject to
protection under the Neuse River Basin: Nutrient Sensitive Waters Management Strategy;
Protection and Maintenance of Existing Riparian Areas, Administrative Code T15A: 02B.0233
(NCAC .0233). Feature A and the pond are not subject.
This letter only addresses the applicability of the Neuse Buffer Rules. For information
relevant to wetlands and other impacts, please contact the Central Office at 733-1786. Thank you
for your attention to this matter and if this office can be of any assistance or if you have additional
questions, please do not hesitate to contact us.
Sincerely,

F\LE C?p?
On August 8, 2002 the Division of Water Quality (DWQ) was notified by receipt of your
application regarding your plan to fill wetland for the purpose of the Autumn Park PUD in Wake
County. Approval from DWQ is required to disturb these areas. Please provide seven copies of the
following information and refer to the DWQ# listed above in your reply. In particular as described in
15A NCAC 2B .0502, we will require you to locate all streams and ponds on the property. Please
show these on maps of suitable scale (for instance 1" = 100 feet) so we can begin to determine your
projects' compliance with 15A NCAC 2H .0500.
1. The stormwater plan must show diffuse flow through the buffers.
2. Lots 46 & 47 show impacts in Zone 1 with sewer easement encroachment. Please provide
information as to why these can't be avoided or redesigned to avoid these impacts.
Please telephone me at 919-733-1786 if you have any questions or would require copies of
our rules or procedural materials. This project will remain on hold as incomplete in accordance with
15A NCAC 2H .0505(c). The processing time for this application will begin when this information is

Re: Pre-Construction Notification Application Form for Autumn Park PUD
Dear Ms. Jones,
Attached you will find one copy of the completed PCN Application Form for proposed wetland
and Neuse Buffer impacts for the Autumn Park PUD in Holly Springs. Included with the
completed PCN Application is a copy of the "Notification of Jurisdictional Determination" issued
by you on August 22, 2001, along with a copy of the surveyed, approved wetland delineation
(wetland delineation was completed by Brady & Associates Forestry Service). As required, a
"Wetland Impact Analysis" map is included with this application that indicates proposed site
development, extent and location of all wetland and Neuse Buffer areas on the property and all
proposed impacts to these areas. Six individual impact locations are identified and appropriately
labeled on this map. One area of Neuse Buffer impact that is not labeled is on lots 46 and 47, in
the east corner of the site. This impact is not labeled because is consists solely of grading and
revegetation of areas within Zone 2 only, which is an "Exempt" activity. No impervious
structures or decks will be constructed within the Neuse Buffer in this location or any other
location where not represented as a proposed impact in this application. Lastly, a copy of each of
the USGS map and the Soil Survey map with the property boundaries identified thereon is
included with this application.
A Neuse Buffer concurrence meeting was held on this site on June 27, 2002. On this date, Ms.
Debbie Edwards from the DWQ Raleigh Regional Office confirmed that the only feature on the
property that required maintenance of Neuse Buffers is the southern-most pond near the existing
trailer park, as indicated on the "Wetland Impact Analysis" map. To date, Spaulding & Norris,
PA, has received no written confirmation of this assessment for inclusion with this application.
Please do not hesitate to contact me if you have questions, comments or concerns about this
application. Thank you in advance for your time spent reviewing this permit application.
Sincerely,
Scott Mitchell, PE, LSS

Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide
information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The street and lot layout is designed around wetlands & Neuse Buffers as much as is practical
The proposed geenway is located on the east side of the northern-most pond and wetland area
to avoid additional wetlands impacts. Greenway crossing at impact point #3 will be constructed
of pressure treated timbers, raised above the existing grade.
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.
Page 9 of 12
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/strmgide.html.
1. Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if more space is needed.
No mitigation is required for proposed impacts.
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

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 213 .0233
(Meuse), 15A NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 213 .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 2,545 3 None
2 5,132 1.5 None
Total 7,677 None
* 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.
Page 11 of 12
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 213 .0242 or.0260.
Mitigation is not required for proposed impacts.
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.
Other than vehicle paths, no impervious surfaces exist on the property. The total proposed
impervious acreage is approximately 21.2 acres. The total acreage of the site is 49.5 acres
Where necessary, concentrated stormwater flows collected by storm drainage systems will be
directed through appropriately designed level spreaders prior to entering Neuse Buffers
XH. 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 generated by this project will be collected by the Town of Holly Springs sanitary
sewer system and ultimately treated and discharged at the Utley Creek WWTP
XM. Violations (required by DWQ)
Is this site in violation of DWQ Wetland Rules (15A NCAC 2H.0500) or any Buffer Rules?
Yes ? No M
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).

Size and Location of Property (waterbody, Highway name/number, town, etc.): The property is
located on the southeastern side of Avent Ferry Road (SR 1115), approximately 0.4 miles southwest of its
intersection with Piney Grove-Wilson Road (SR 1101), in Holly Springs, Wake County, North Carolina.
Basis for Determination: The site contains wetlands and stream channels with indicators of ordinary
high water marks, located adjacent to an unnamed tributary of Basal Creek, above headwaters, in the
Neuse River Basin.
Indicate Which of the Following Apply:
There are waters of the U.S., to include wetlands, on the above described property which we strongly suggest
should be delineated and surveyed. The surveyed wetland lines must be verified by our staff before the Corps will
make a final jurisdictional determination on your property.
Because of the size of your property and our present workload, our identification and delineation of your wetlands
cannot be accomplished in a timely manner. You may wish to obtain a consultant to obtain a more timely
delineation of the wetlands. Once the consultant has flagged a wetland line on the property, Corps staff will
review it, and, if it is accurate, we strongly recommend that you have the line surveyed for final approval by the
Corps. The Corps willinot make a final jurisdictional determination on your property without an approved survey.
X The waters of the U.S., to include wetlands, on your lot have been delineated, and the limits of the Corps
jurisdiction have been explained to you. Unless there is a change in the law or our published regulations, this
determination may be relied upon for a period not to exceed five years from the date of this notification.
There are no waters of the U.S., to include wetlands, present on the above described property which are subject to
the permit requirements of Section 404 of the Clean Water Act (33 USC 1344). Unless there is a change in the law
or our published regulations, this determination may be relied upon for a period not to exceed five years from the
date of this notification.
Placement of dredged or fill material in wetlands on this property without a Department of the
Army Permit is in most cases a violation of Section 301 of the Clean Water Act (33 USC 1311). A
permit is not required for work on the property restricted entirely to existing high ground. If you
have any questions regarding the Corps of Engineers regulatory program, please contact
Amanda D. Jones at telephone ber 919 876 - 8441 extension 30
