To Whom It May Concern:
On April 5, 2007, S&EC received a letter from your office regarding DWQ No. 06-1347 requesting
additional information to process the permit application. Specifically, your office cited deficiencies in
our application related to the following:
1. With regard to the bioretention areas, the following items need to be addressed in the
resubmittal:
• Add a specification for stakes for the trees.
A tree planting detail with stakes has been added.
• Add a planting detail (approximately one-half the root ball should be placed above
the surface of the planting soil).
The planting details have been added with approximately %2 of root ball above
planting surface.
• Add a pretreatment system for removing sediment from the stormwater before it
enters the bioretention area.
Forbays have been added prior to each bioretention area to provide sediment
removal.
• The depth to groundwater must be provided in order for DWQ to approve the
bioretention systems. Please provide appropriate documentation of this.
The depth of ground water has been determined and is shown on the bioretention
worksheets.
• Modify the specifications for the planting soils; the currently proposed mix that
includes 10 to 25 percent clay will cause clogging. The NCSU Department of
Biological and Agricultural Engineering has a recommendation for a bioretention soil
media that can be accessed at., http://www.bae.ncsu.edu/topic/bioretention/design-
soil.html.
The planting soil mix has been revised.
• The bioretention soil should not be compacted with heavy equipment.

Notes have been added that the bioretention soil is not to be compacted by heavy
equipment.
• The fertilizer specifications should state that this is only an initial application to
establish the plants and after that fertilizer shall not be used.
The fertilizer specification has been revised to state that the fertilizer is an initial
application only.
• The use of Quercus Phellos (willow oak) is not recommended in a bioretention area
with an underdrain due to the high probability of the root system infiltrating the
underdrain.
Willow Oaks are no longer specified within the plan.
• The correct scientific name of witch hazel is Hamamlis verginica.
The scientific name for witch hazel has been corrected.
• DWQ recommends a parallel underdrain in bioretention area No. 2 to provide back-
up in case of clogging.
An additional underdrain has been added to bioretention area #2.
S&EC contacted Cyndi Karoly within three weeks of receiving the request to notify DWQ that the
engineer was working on a resolution to these issues and would be submitting within one week of
April 30, 2007. In response to these requests, you will find the attached documents that contain
revised plans, bioretention calculations, wetland impact map and bioretention worksheets for the
BMP devices. If you require further information or would like to discuss the project in detail, I can be
reached at our office at 919-846-5900.

Narrative
The purpose of this project is to construct the subdivision road infrastructure for a
portion of the Howard Farms subdivision in Person County, North Carolina. The
infrastructure will include a public subdivision road constructed to NCDOT standards.
The road will have a pavement width of 18' and end in a cul-de-sac.
The project site is approximately 8 miles south of Roxboro in Person County. A
Vicinity Map showing the project location has been included on the Cover Sheet of the
Plans. Soils on the site are primarily Hydrologic Soil Group B. The site is located in the
Neuse River Drainage Basin.
Work on this project will include grading, road construction and installation of
required storm drainage pipes. Sediment and erosion control devices are shown on the
Plan and Profile Sheets. The Plan and Profile Sheets provide the profile of the centerline
the proposed roads. Erosion control devices include a temporary construction entrance,
erosion control matting, check dams and silt fence. The side ditches along the road have
been designed using temporary and permanent linings that will prevent erosion. during the
10-year storm event.
Two bioretention areas are proposed to filter stormwater runoff from the roadside
ditches. The bioretention areas have been designed by the 1999 NCDWQ BMP Manual.
Bypass channels will route larger storms around the bioretention areas.
