Thank you for your time and willingness to discuss the post construction storm water design for the Waynesville
Commons project last Friday. As discussed, this project presents unique site constraints and it was refreshing
to attend a meeting where these issues were openly discussed and potential solutions explored. As a result of
our discussions, Waynesville Commons Retail Associates, LLC ("Developer") respectfully withdraws its prior
submittals and will work diligently with DWQ's 401 Staff ("DWQ") to find a solution to treatment issues prior to
resubmitting plans.
It was agreed the Wal-Mart white roof was an environmentally friendly solution compared to roofing systems of
older technology, yet a higher level of treatment will be required. The solution discussed entails eliminating
direct discharge to the stream and diverting rain water from the white roof to the adjacent bio basin. This will
result in an initial two foot standing water scenario in the pond. The Developer will confirm soil permeability by
performing field tests. Permeability is anticipated to be higher than average due to the geological makeup of the
underlying substrate. DWQ will confirm the survivability for the specific plant root structures proposed to line the
basin. It is believe that should water exceed normal levels (up to 24"), this condition will be temporary only and
the accelerated permeability will allow proper drainage within the time limits required for plant survival. Should
both the permeability data and plant survivability be confirmed, this solution will be an acceptable treatment
solution for the Wal-Mart white roof discharge.
Regarding the remainder of the site, a more global view will be taken by DWQ rather than the strict evaluation of
each BMP per specific drainage areas. The Developer must address the 85% TSS rule throughout the site but
DWQ will allow nitrates and phosphorus to be a weighted average over the entire site rather than per individual
BMP. The area of most concern was the dry detention basin in the NW corner of the site. Due to size
constraints, expanding the area to a wet basin was not feasible and other solutions will be explored. In addition,
a discussion was held regarding the wide variety of BMP's used by different states to treat similar conditions.
The Developer asked consideration for BMP's used by other states should they be more effective. DWQ will
consider such a scenario should the proper documentation be submitted.
Thank you again for your willingness to find a quick and workable solution to open items noted above.
