Re: Project: DWQ Project # 07-1290
Subject: Re: Request for more information
Dear Ms. Karoly,
In response to your letter dated August 6, 2007 requesting additional information, we are submitting five
copies of the additional information as addressed below.
Additional Information Requested:
1. The sewer line was moved further up the slope, away from the Cabin Branch stream buffer, to
alleviate impacts numbered 3 - 13. Other than the perpendicular crossings, which are specified as
directional bores to minimize impacts, there are only two additional impacts (#5 and #6). Impact
#5, 0.001 acre of Zone 2 impacts, slightly clips the buffer to avoid the sewer having to be any
deeper. Impact #6, 0.007 acre of Zone 2 impacts, has been pulled away from the buffer as far as
possible without manhole #93 being placed on an existing lot.
2. The individual impacts have been listed separately on the PCN form.
3. There is no longer an impact in that location.
4. Two additional plant species have been added to the bioretention facilities and one additional plant
has been added to the wetlands.
~~~ ~
5. The PCN form has been revised to reflect Mike Horan's note. ~ ~'~' l~ f.t~ j

wetlands, open water, and stream channels associated with the project. Each impact must be
listed separately in the tables below (e.g., culvert installation should be listed separately from
riprap dissipater pads). Be sure to indicate if an impact is temporary. All proposed impacts,
permanent and temporary, must be listed, and must be labeled and clearly identifiable on an
accompanying site plan. All wetlands and waters, and all streams (intermittent and perennial)
should be shown on a delineation map, whether or not impacts are proposed to these systems.
Wetland and stream evaluation and delineation forms should be included as appropriate.
Photographs may be included at the applicant's discretion. If this proposed impact is strictly for
wetland or stream mitigation, list and describe the impact in Section VIII below. If additional
space is needed for listing or description, please attach a separate sheet.

local stormwater requirement, etc.):
Current land use in the vicinity of the pond:
Size of watershed draining to pond:
Expected pond surface area:
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. There are several streams
on the property and we limited crossing_to just two streams that intersect the property. Access
to the entire property is not possible without crossing the streams. Both streams were crossed at
nearly 90 degrees. All development was limited areas of 15% slopes or less, which leaves
almost half of the property undeveloped. All lot boundaries were kept out of stream buffers. In
order to server the development with sewer, it was necessary to place the proposed pump station
and sewer main along Cabin Branch. The sewer easements were moved out of the buffer as
much as possible and all buffer impacts were limited to Zone 2 except for 3 crossings. The
crossings have been shown as directional bore to further limit impacts to the streams. All storm
water runoff is shown being directed through through a high TSS removal BMP such as a
constructed wetland or bioretention facility.

VIII. Mitigation
DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on January 15, 2002, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
http:,'/h2 o.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.
The proposed mitigation is payment to the NCEEP. See the attached letter of approval
for payment to NCEEP. The developer will also donate 37.76 acreas of the propert aX long
Cabin Branch as a Conservation Easement.
2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement
Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at
[phone] to determine availability, and written approval from the NCEEP indicating
that they are will to accept payment for the mitigation must be attached to this form. For
additional information regarding the application process for the NCEEP, check the NCEEP
website at http://h2o.enr.state.nc.us/wrp/inclex.htm. If use of the NCEEP is proposed, please

Riparian Buffer Restoration Fund). Please attach all appropriate information as identified
within 15A NCAC 2B .0242 or .0244, or .0260.
XI. Stormwater (required by DWQ)
Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss
Stormwater controls proposed in order to protect surface waters and wetlands downstream from
the property. If percent impervious surface exceeds 20%, please provide calculations
demonstrating total proposed impervious level. The total site acreage is 114 ac. The existing
impervious acreage is 0 ac. The proposed impervious acreage is 27 ac, or 24 %. The proposed
impervious surfaces include roadway and sidewalks (11 ac), building f~prints and driveways
(15 ac) and the amenity center and pump stations 1 ac . DuringY construction, streams will be
protected by sediment traps and basins fed by diversion ditches and berms. All erosion control
measures will be built in accordance with NCDENR standards. Stormwater controls for the
proposed subdivision include four constructed wetlands and three bioretention areas to
effectively handle all discharge from the subdivision. These devices will be built in accordance
with DWQ BMP guidelines.
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.
A sanitary sewer system will be utilized for the proposed subdivision. The sewer will rg~avity
flow to an onsite pump station and will then be discharged via force main into an existin fg orce
main in Glen Haven Subdivision to the north. From Glen Haven, the force main runs to a point
where it becomes rg avity sewer on NC Hwy 42 and eventually discharges into the Little River
Water Reclamation Facility, which is operated by the Town of Clayton.
XIII. Violations (required by DWQ)
