REQUEST FOR MORE INFORMATION
Dear Sir or Madam:
On August 21, 2006, the Division of Water Quality (DWQ) received your application dated
August 21, 2006, to fill or otherwise impact 1421inear feet of perennial stream impact, and 4,218
square feet of Zone 1 Neuse River basin protected riparian buffers and 3,088 square feet of Zone
2 Neuse River basin protected riparian buffers, to construct the proposed residential subdivision.
On October 10, 2006, and March 8, 2007, the DWQ received additional information from you,
however, the DWQ has determined that your application remains incomplete and/or provided
inaccurate information as discussed below. The DWQ will require five copies of the additional
information requested in order to process your application to impact protected wetlands and/or
streams on the subject property. This project has been placed on hold until the following criteria
has been meet. Please provide the following information so that we may continue to review your
project.
Additional Information Requested:
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.
• Add a planting detail (approximately one-half the root ball should be placed
above the surface of the planting soil).
• Add a pretreatment system for removing sediment from the stormwater before it
enters the bioretention area.
• The depth to ground water must be provided in order for DWQ to approve the
bioretention systems. Please provide appropriate documentation of this.
• 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

• The bioretention soil should not be compacted with heavy equipment.
• The fertilizer specification should state that this is only an initial application to
establish the plants and after that fertilizer shall not be used.
• 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.
• The correct scientific name of witch hazel is Hamamlis virginica.
• DWQ recommends a parallel underdrain in bioretention area No. 2 to provide
back-up in case of clogging.
Please contact the DWQ within three weeks of the date of this letter to verify that you have
received this letter and to provide us with a date that we may expect to receive this requested
information. If we do not receive this requested information within one week of the date you
indicate it will be forthcoming, your project will be withdrawn and you will need to reapply with
a new application and a new fee. Please contact me in writing and Lauren Cobb of the DWQ
Raleigh Regional Office. If we do not hear from you within three weeks, we will assume that
you no longer want to pursue this project and we will consider the project as withdrawn.
This letter only addresses the application review and does not authorize any impacts to wetlands,
waters or protected buffers. Please be aware that any impacts requested within your application
are not authorized (at this time) by the DWQ. Please call Ms. Cyndi Karoly or Mr. Ian
McMillan at 919-733-1786 if you have any questions regarding or would like to set up a meeting
to discuss this matter.
Si ly,
Cyndi Karoly, Supervisor
