Request for More Information Response
DWQ Project #08-0499
TSC #6991.101
Ms. Lucas,
In response to your letter dated January 23, 2009 please accept the accompanying revised FedEx
- Greensboro Distribution Center Construction Plan sheets and site photos your review and
approval. In reference to your individual concerns we offer the following:
1. The flow splitter device details have on sheets 0008.07 & 0008.09 have been revised. The
proposed bypass pipe is intended to be a temporary line for use while the grassed filter strip is
allowed to take hold.
2. Included with this submittal are four (4) site photos showing the filter strip areas down slope of
the proposed level spreaders.
3. Sheets 0008.06 & 0008.08 have been revised to clearly show that the vegetated shelf
associated with each wet detention pond is planted with appropriate vegetation over the entire
ten-foot shelf.
The above and accompanying information address all of the comments provided in your letter. If
you h any additional quest s or comments please contact me by phone [phone] or e-
mail ascales schneide Or .corn.
Res a fully,
Th Sc neide C tion
