information

Dear Mr. McMillan and Mr. Gyamfi:
OENR - WATER QUALITY
WETLAWS AND STORMWATER BRANCH
This letter is in response to your letter dated July 22, 2009 which requested additional
information for the proposed Rose of Sharon development. The following restates your
questions/comments and is then followed by our response.
Additional Information Requested
1. Diffuse Flow Plan
a. To meet the diffuse flow requirements, a 50 foot minimum width of the filter strip is
required. Unless the vegetation downstream of each proposed 30 foot grass filter
strip is considered "dense vegetation ", you will need to revise the level spreader
length calculations. The filter strip width is measured from the level spreader lip to
the top of stream bank. The required filter strip length per cfs of flow shall be
calculated as a weighted average of the lengths required for each vegetation type
and/or density. Please refer to Section 13.3.4 of the NCDWQ BMP Manual for
further guidance.
b. Please provide photos of the vegetation within the area below the 30 foot filter strip
for each level spreader.
On July 30, 2009, S&EC had a phone call with Ms. Annette Lucas and Mr. Joseph
Gyamfi discussing the issues regarding the level spreaders addressed in this letter.
During the phone call, it was explained to Ms. Lucas and Mr. Gyamfi that the filter strips
below Level Spreaders 1 and 2 will be maintained in grass.

Mr. Gyamfi requested a copy of the revised plan that shows the area directly below Level
Spreader 1 to be grassed. It is important to note that this area is also within the sanitary
sewer easement that will be permanently maintained by Durham. Please see the attached
sheet U6 which contains the plan and details that demonstrate that the filter strip will be
grassed.
Additionally, we discussed Level Spreader 2 and the vegetation immediately below it.
As demonstrated by the attached picture, the area where Level Spreader 2 will be built is
completely grassed (in front of and to the right of the barn). It is important to note that
this property was an active farm and therefore, in this particular area, there is no wooded
buffer along the stream. We have also included Sheet C4a which clearly shows the
existing barn (to remain) that is shown in the attached photograph. Therefore, Mr.
Michael Fiocco (Civil Consultants) correctly accounted for the vegetation as grassed
within the worksheets supplied to DWQ with the original application.
Please feel free to call me if you require any further explanation.
Sincerely,
Loll?e J. Thomson
Regulatory Specialist

REQUEST FOR MORE INFORMATION
Dear Ms. Beischer:
On July 1, 2009, the Division of Water Quality (DWQ) received your. application dated July 1, 2009 to
place fill within or otherwise impact 0.035 acres of 404/wetland (temporary impact), 275 linear feet of
permanent, perennial stream impact, 272 linear feet of temporary, perennial stream impact, 20 linear feet
of temporary, intermittent stream impact, f9 linear feet of temporary, isolated intermittent stream impact,
0.54 acres of open water (Bond), and 16,061 square feet of Zone 1 Neuse River basin protected riparian
buffers and 10,548 square feet of Zone 2 Neuse River basin protected riparian buffers to construct the
proposed residential development on the subject property. The DWQ has determined that your
application was incomplete and/or provided inaccurate information as discussed below. The DWQ will
require additional information in order to process your application to impact protected wetlands and/or
streams on the subject property. The DWQ will require additional information in order to process.your
application to impact protected wetlands and/or streams on the subject property. Therefore, unless we
receive five copies of the additional information requested below, we will place this project on hold as
incomplete until we receive this additional information. If we do not receive the requested information,
your project will be formally returned as incomplete. Please provide the following information so that we
may continue to review your project.
