Subject Property: Shoffner NC 73 Project
REQUEST FOR MORE INFORMATION: STORMWATER MANAGEMENT PLAN
Dear Mr. James:
On January 31, 2008, the Division of Water Quality (DWQ) issued a 401 Water Quality
Certification to fill or otherwise impact 262 linear feet of perennial stream and 837 linear feet of
intermittent unnamed tributary to Irish Buffalo Creek in order to construct a retail center in
Cabanas County, as described in your applicant received by the DWQ on January 14, 2008.. In
order to meet Condition 4 of the 401 Certification for this project, a stormwater management
plan, was received by the DWQ on January 10, 2007. The DWQ has determined that your
stormwater management plan was incomplete as discussed below.
Additional Information Requested:
1. The DWQ does not approve the use of the proposed slotted drain level spreader. These
devices have proven problematic in their applications in North Carolina. If the applicant
wishes to use a level spreader, then it should be designed per Chapter 8 of the NC BMP
Manual. If the sole purpose of the device is to reduce velocities from the pipe outlet, a
rip rap dissipater device would also be appropriate. In addition, if the applicant chooses
to use a properly designed level spreader on this project, then he should use our more
recent Level Spreader Inspection and Maintenance Form, available at:
http://h2o.enr.state.tic.us/sufbmp forms.htm.
2. If the project is in the jurisdiction of the City of Concord, then please provide
documentation of the City of Concord's approval of the stormwater management plan for
this project by providing EITHER:
