RE: PCN Application Re-submittal
Gray's Creek Subdivision, Wake County, NC
DWQ Project #: 08-0472
BLC Project #: 60022
Dear Mr. McMillan:
We received NC Division of Water Quality's letter returning the subject project application
dated December 22, 2008. NCDWQ returned the application due to lack of a timely response to
a request for more information on September 22, 2008. We have now compiled the information
requested and are re-submitting the complete application package.
There were four items noted in the request for more information letter. Annette Lucas and Keith
Roberts met to discuss the first item requiring all stormwater from the entire site to be directed to
one of the retention basins. Ms. Lucas agreed to allow scour holes for the discharge points along
Crimson Oak Lane. As requested in item #2, scour holes #4 and #5 were added to achieve
diffuse flow from the retention basins, which were designed based on the 25-year storm rather
than the 1 inch storm. A report from Jason Hall, LSS of Central Carolina Soil Consulting, PLLC
is included with the Stormwater Management Plan (SMP) attachments that documents the
SHWT. The project engineer, Mr. Keith Roberts reviewed the retention basin inverts to ensure
they are one foot above the SHWT as requested in item #3. The SMP includes plans of the entire
site, plan details, a section view of the retention basins, and a construction sequence all at the
requested scales (item #4). For each of the two ponds, a signed and notarized operation and
maintenance agreement are included with the SMP (item #4). Five copies of this letter and
revised PCN application package along with a new $240 application fee have been provided.

this project (including all prior phases) in the past?
5b. If yes, explain in detail according to "help file" instructions.
Burdette Land Consulting, Inc. (BLC) conducted a surface water and wetland delineation of the property during April,
2006. The wetland boundary has not been verified by the USACE. An Approved Jurisdictional Determination Form and
supporting Wetland Data Forms for the relevant reach to which impacts are proposed were attached to the original PCN
application submitted on March 12, 2008. On March 18, 2008, we received the attached letter from NCDWQ requesting
more information regarding the stormwater management and the nonperpendicular angle of the road crossing. On March
28, 2008, we received an email from Jamie Shern of the USACE indicating permit conditions required for using
preservation to satisfy mitigation requirements and pre- and post-construction inspection of requirements of impacts of
149 linear feet of stream channel after discussing these and other points via telephone. A revised PCN application was
submitted on August 25, 2008 that included the following changes: 1.) additional justification for the unavoidable, non-
perpendicular road crossing; 2.) avoidance of wetland impacts #4 through #6; a new culvert size; permanent stormwater
management BMPs; and preservation through the restrictive covenants for the subdivision. On September 22, 2008, we
received another request for more information letter (attached) about the stormwater management plan for the project.
The NWP 29 was statutorily approved on October 9, 2008. Jennifer Burdette of BLC contacted Ian McMillan on
November 21, 2008 and explained that we were still working on the requested information. However, before we
submitted the information, we received the attached Notice of Return letter on December 22. 2008. This PCN application
addresses all of NCDWQ's previous requests for additional information regarding stormwater management for the project.
6. Future Project Plans
6a. Is this a phased project? Z Yes ? No
6b. If yes, explain.
However, this PCN application covers the all phases of the project; therefore, future permit requests are not anticipated
for this project.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
The applicant requested a delineation of surface waters and wetlands prior to preliminary plan development to avoid impacts
to jurisdictional areas to the maximum extent practicable. However, one stream channel along with its abutting wetlands
dissects the property making it unavoidable. The engineer was unable to align the road crossing labeled as Road Impact #1
perpendicularly due to site constraints that are further explained in Mr. Keith Roberts' attached letter.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The project engineer was still able to minimize the impact to the channel to less than 150 linear feet by using headwalls. A
cross-section showing the height of the headwall is attached. The culvert will be buried to allow aquatic life passage.
Additionally, the middle culvert is centered on the stream channel and the two side culverts will be installed at the bankfull
elevation to maintain the stream channel's original pattern, dimension, and profile. A cross-section of the culverts is provided
as Figure 4.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for ® Yes ? No
impacts to Waters of the U.S. or Waters of the State?
2b. If yes, mitigation is required by (check all that apply): ? DWQ ® Corps
? Mitigation bank
2c. If yes, which mitigation option will be used for this
®Payment to in-lieu fee program
project?
® Permittee Responsible Mitigation
3. Complete if Using a Mitigation Bank
3a. Name of Mitigation Bank:
3b. Credits Purchased (attach receipt and letter) Type Quantity
3c. Comments:
4. Complete if Making a Payment to In-lieu Fee Program
4a. Approval letter from in-lieu fee program is attached. ® Yes
4b. Stream mitigation requested: linear feet
4c. If using stream mitigation, stream temperature: ® warm ? cool ?cold
4d. Buffer mitigation requested (DWQ only): square feet
4e. Riparian wetland mitigation requested: acres
4f. Non-riparian wetland mitigation requested: acres
4g. Coastal (tidal) wetland mitigation requested: acres
Page 7 of 11
PCN Form - Version 1.3 December 10, 2008 Version
4h. Comments: The applicant avoided impacts to streams and wetlands where possible and minimized stream channel
impacts that were unavoidable to the maximum extent practicable as described above. A 50-foot-wide riparian buffer will be
maintained around the stream channel present within the development in accordance with Town of Fuquay-Varina's
requirements and will serve as a permanent, vegetative buffer to that stream channel.
BLC believes that compensatory stream channel mitigation should not be required for the project because the unavoidable stream
channel impact does not exceed the 150 linear foot impact threshold established for mitigation by the NCDWQ and the USACE in
most cases, and the applicant has exercised every available option to minimize the impact. Because the proposed jurisdictional
wetland impact of 0.367 acre exceeds the USACE's (0.10 acre) threshold for mitigation, BLC believes that riparian wetland
mitigation is required.
The applicant proposes to mitigate jurisdictional wetland impacts at a 2:1 ratio through preservation and compensatory
mitigation. Compensatory mitigation for 0.367 acre of riparian wetland impact will be satisfied through payment to the NCEEP.
NCEEP's wetland mitigation acceptance letter is attached.
5. Complete if Using a Permittee Responsible Mitigation Plan
5a. If using a permittee responsible mitigation plan, provide a description of the proposed mitigation plan.
The remaining 0.367 acre of mitigation required would be satisfied by preserving a large wetland area on the project and
all of those wetlands that will remain within lots through the subdivision's restrictive covenants using the USACE's
standard preservation language and the attached preservation map. (Figure 5). Approximately 8.52 acres of wetland will
be preserved on the site providing a preservation ratio of approximately 23 to 1. It is important to note that 1824 linear
feet of perennial stream channel will also be preserved within the proposed wetland conservation area providing stream
channel preservation at a ratio of approximately 12 to 1.
6. Buffer Mitigation (State Regulated Riparian Buffer Rules) - required by DWQ
6a. Will the project result in an impact within a protected riparian buffer that requires ? Yes ? No
buffer mitigation?
6b. If yes, then identify the square feet of impact to each zone of the riparian buffer that requires mitigation. Calculate the
amount of mitigation required.
6c. 6d. 6e.
Zone Reason for impact Total impact Multiplier Required mitigation
(square feet) (square feet)
Zone 1 3 (2 for Catawba)
Zone 2 1.5
6f. Total buffer mitigation required:
6g. If buffer mitigation is required, discuss what type of mitigation is proposed (e.g., payment to private mitigation bank,
permittee responsible riparian buffer restoration, payment into an approved in-lieu fee fund).

RE: Grays Creek Subdivision
Buffer Crossing
The proposed Grays Creek Subdivision is bounded on the North by Wilbon Road and on the South by
Coley Farm Road. The parcel is divided by a creek that runs NW to SE through (diagonally) through the
site within an area where the parcel narrows. The creek is required to be buffered based on the Neuse River
Rules. Due to the fact that the tract has access to the North and the South the developer had requested that
the crossing through the buffer not be required. However, due to development guidelines within Fuquay-
Varina, the crossing is required. Fuquay-Varina is requiring the crossing due to the size of the subdivision,
entrance locations, emergency vehicle access and 500' limits on cul-de-sac lengths.
Due to site and development regulation constraints, it is impossible to cross the buffer perfectly
perpendicular. As mention previously the site runs North to South and the buffer runs NW to SE within the
narrowest part of the site. Additionally, the design street radius on either side of the buffer can not be
decreased due to design regulations within Fuquay-Varina. The proposed curve radius at the buffer is 200'.
The minimum allowed by code is 200' (see attached email). Based on the geometric configuration of the
site and design constraints we feel that the current layout best minimizes buffer impacts. We also tried to
further decrease impacts with the installation of headwalls on the upstream and downstream side of the
crossing (see included headwall cross section).
Thank you for your consideration on this project. If you need additional information or have any
questions concerning this letter please do not hesitate to contact us.

Dry Extended Detention Basin
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The dry extended detention basin system is defined as the dry detention basin, outlet
structure, pretreatment including forebays and the vegetated filter if one is provided.

incorporate pretreatment other than a forebay.
Important maintenance procedures:
- The drainage area will be managed to reduce the sediment load to the dry
extended detention basin.
- Immediately after the dry extended detention basin is established, the vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- No portion of the dry extended detention pond will be fertilized after the first
initial fertilization that is required to establish the vegetation.
- I will maintain the vegetation in and around the basin at a height of
approximately six inches.
- Once a year, a dam safety expert will inspect the embankment.
After the dry extended detention basin is established, it will be inspected once a quarter
and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in
a Coastal County). Records of operation and maintenance will be kept in a known set
location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

Dry Extended Detention Basin
Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The dry extended detention basin system is defined as the dry detention basin, outlet
structure, pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
? does ® does not incorporate a vegetated filter at the outlet.
This system (check one):
? does ® does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
- The drainage area will be managed to reduce the sediment load to the dry
extended detention basin.
- Immediately after the dry extended detention basin is established, the vegetation
will be watered twice weekly if needed until the plants become established
(commonly six weeks).
- No portion of the dry extended detention pond will be fertilized after the first
initial fertilization that is required to establish the vegetation.
- I will maintain the vegetation in and around the basin at a height of
approximately six inches.
- Once a year, a dam safety expert will inspect the embankment.
After the dry extended detention basin is established, it will be inspected once a quarter
and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in
a Coastal County). Records of operation and maintenance will be kept in a known set
location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
