Re: Reply to the Division of Water Quality's Request for More Information V'Tt TLANDS AND STORMWATER BMNCFI
Traditions Subdivision-Phase 1
Wake County, NC
To Mrs. Karoly and Mr. McMillan:
The purpose of. this letter is to respond to your Request for More Information letter dated October 26,
2009: The original questions/requests are copied below as they appear within letter and are then followed
by our response. In•addition to these responses, it is important to note that the "applicant section"
required a modification within the Pre-Construction Notification (PCN) application; therefore we have
included a revised' page.2 to include the modified information. Furthermore, through additional design of
this project, the engineer has identified a necessary sanitary sewer connection within the northeastern
section of the proposed Traditions-Phase I subdivision. This sanitary sewer connection to an existing
manhole is resulting in 330 ftz of Zone 2 of the Neuse Riparian Buffers. Therefore, in addition to a revised
page 2 of the PCN application, we have included updated impact exhibits and a revised page 6 for your
review.
Additional Information Requested.
1. Please re-submit your site plans on full plan sheets at a scale of no smaller than 1"= 50' with
topographic contours shown and lot numbers shown for reference. Also, please include this
information in PDF format on a disk.
Please see attached full size plan sheets at 111=50', in addition to a CD including all maps In pdf
format.
2. This office believes that the intermittent stream impact labeled on the plans as Impact 2 can be moved
or reconfigured to minimize the impacts.to the stream. Please revise the plans to minimize the
impacts.
The applicant and project engineer have evaluated possible alternatives that avoid or minimize
these Impacts and have determined that they can not minimize them beyond what was
originally proposed. Please see the attached justification letter signed by the applicant's
representative and the project engineer.
3. Please provide an inventory of imperviousness surfaces in each drainage area.. The inventory should
include all proposed building footprints, roads, driveways, sidewalks, gravel-surfaced areas, amenity
areas, etc. A Stormwater Management Plan (SMP) must be provided for any drainage areas that
exceed 24 percent imperviousness. For each BMP, provide a completed BMP Supplement Form with
all the required items (see httP:11h2o.enr state.nc.usl ulbmo forms.htm). Per NCAC 2B 15A:
02H.1000, a "drainage area' is defined as `the entire area contributing surface runoff to a single point.

Please see attached stormwater management plan (SMP) for all drainage areas of the
Traditions-Phase I that exceed 24% Imperviousness.
We anticipate that this answers all of the DWQ's questions in order to complete the final review process
requested for the written concurrence of Water Quality Certification 3705 and Riparian Buffer
Authorization. If you have any further questions or any additional explanation is needed, please don't
hesitate to call.

Dear Mr. Zarzecki,
In response to the DWQ's letter dated October 26, 2009 requesting additional information, you
have asked us if it would be possible to remove the proposed impacts to the
ephemeral/intermittent, first order stream (exempt from the Neuse Buffer Rules) that is in the
proposed lots between Lemongrass Lane and Autumn Meadow Lane. Though it may look like
minimizing grading would remove any impacts, it is a more complicated situation than that.
First, the grade on Lemongrass Lane at the bottom of the neighborhood is anywhere from 25 feet
to 34 feet above the channel. This was necessitated by the overall grade of the site and the need
to reduce impacts to the buffers, preserve some large trees as required by the Town zoning
approval and design streets to the Town of Wake Forest specifications. These street
specifications include maximum slope, curvature values and sight distance requirements. In fact,
you will notice that in the lower portions of the road we will have to build walls to avoid buffer
impacts needed to accommodate street grades.
Second, because the road is higher than the existing grade at the lower portions of the site, we
have had to raise the site to accommodate this. The channel necessary to drain this area runs
through a 27 foot slope required by the road grade. Therefore, even if we removed the lots
further up hill, we still would have to drain the water through a 60 foot storm pipe system prior
to reaching the natural stream channel.
We estimate that in order to avoid this stream we would need to loose at a minimum seven (7)
residential building lots.
Finally, lowering the grade to reduce the amount of channel impacted would then make the
streets out of compliance with Town codes. Home sites would certainly be hard to market, and
most likely completely unable to be built upon.
Even if it were possible to avoid direct impacts to this stream, indirect impacts to this stream
would inevitably occur given the vicinity to adjacent lots and roads.
Given all of these factors, the significant amount of avoidance to higher quality streams and
wetlands proposed for this property, and the ephemeral/intermittent nature of this stream, we
believe that it is impracticable to avoid impacts to this stream.
I hope this helps explain why we unfortunately need to impact this stream channel. If you have
any questions, please call.
Since -ely,
Robert Weintraub
