Re: Response to On -Hold Notice - DWR # 15 -0428;
Glen Creek Subdivision 401/404, Buffer Compliance Application
Wake County, NC
SEPI Project # EN14.051.00
The purpose of this letter and the attachments is to provide the response to the email from Ms.
Cherri Smith of the Raleigh Regional office of the North Carolina Division of Water Resources
(DWR) dated May 26, 2015. Within the email two items were requested: clarification of the need
for a stormwater plan and additional information required on the submitted impact maps. Further
explanation is provided below.
In the initial April 29, 2015 permit application submittal the impervious surface was stated to be
only 11% at most. Due to the percent impervious and the type of development planned, a NC
Division of Water Resources stormwater plan approval is not required by for this project. As part
of its site plan approval process Wake County, a certified county, is requiring and currently
reviewing a stormwater plan which includes a diffuse flow plan. We therefore request a
conditional 401 permit be issued based on Wake County's approval of the stormwater plan. A
copy of Wake County's approval will be forwarded to NCDWR once it has been issued.
In addition to the stormwater clarification, additional map data (i.e. date, contours, company
name and cross section of culvert crossing) was requested. This additional information has been
added to the attached maps.
If you have any questions, please call me at (919) 573 -9931.
Sincerely,
SEPI Engineering & Construction
Sean Clark
Environmental Division Manager
