Memo To: John Dorney
Ian McMillan
NCDENR-DWQ
Ph: 919-788-0224
fax: [phone]
Subject: Broughton Properties Subdivision and Oak Forest Drive Extension Water
Quality Certification for Stream Crossing.
On July 20, 2007 the following met in the offices of DWQ on Crabtree Blvd. to discuss
the subject project:
John Dorney, DWQ
Mary Jo Lee, CH Engineering
Tom Hepler, CH Engineering
Ed Bailey, Developer
This meeting was afollow-up of a meeting held in DWQ office with Ian McMillan and
Annette Lucas in which we were encouraged to coordinate with John Dorney.
This project involves the extension of a City of Raleigh Street east across an un-named
stream which flows from South to North into an in-line wet-pond which was designed as
a mitigation measure for the implementation of the Triangle Towne Center. John
Dorney was familiar with the Triangle Towne project and the purpose of the wet-pond.
Apparently, the wet pond was a measure installed to compensate for wetlands which
were destroyed with the shopping center's construction. It can be modified to be used
for stormwater storage but credit cannot be taken for treatment of water quality. Water
quality treatment should take place on-site.
CH Engineering was directed to develop a schematic plan for stormwater treatment for
quality for the entire subdivision. Description, general size and siting of potential BMP
devices should be shown on a plan in order to treat and reduce the TSS and Nitrogen.
It is understood that these individual devices would be reviewed by the City of Raleigh
in accordance with DWQ along with measures opted to reduce runoff impact as a result
of pre-post stormwater calculations. BMP worksheets would not be necessary at this
stage but would be submitted at the site plan submission stage to the City of Raleigh.

Page 2
CH Engineering indicated that field location of stream and wetlands were being
performed by Eric Galamb. As soon as this is complete and has been confirmed by
DENR and Corps of Engineers it should be mapped and incorporated onto the next plan
submission to DWQ along with the BMP's proposed and the completed necessary
forms.
In the meeting in May, we were asked to investigate modifying the culvert such that its
angle with the roadway falls between 75 degrees and 105 degrees, however it should
be placed to follow the natural stream bottom. The length of stream impact cannot
exceed 150 linear feet, otherwise a special permit must be pursued.
If you have additional comments please indicate in the space below and return to CH
Engineering office via mail or fax. If we do not hear from you, we plan to proceed with
preparing the plans and documents per this memorandum for submission in pursuit of
the Section 401 Water Quality Certification. Thanks for your time and input on this
matter.
