Dear Mr. McDowell;
RE: Division of Water Quality'staff review of Wetland and Floodplain Monitoring Report: 2006
South Buffalo Creek Stormwater Wetland Project
DWQ # 2001-0263, Guilford County
Division of Water Quality staff have reviewed your report dated February 22, 2007 concerning the
Floodplain and Wetland monitoring for the abovementioned project. I apologize for the tardiness of our
response and we will strive to respond in a more timely manner in the future.
Basically, the Division believes that since the water control structure has not yet been fully operational,
that our requirement for five years of monitoring after construction has not really begun. Therefore we will
need to extend the monitoring time for this facility to ensure that we have five years of post-installation data.
The data that have been gathered to date will provide a valuable background data upon which to compare the
effect (if any) of the facility on the adjacent wetlands. Please provide a written plan to DWQ in response to
address this issue.
We concur with your plan to mow herbs and plant four foot tall trees in area D5. We also concur with
your plan to change the monitoring method in area D8 and request that maps, photos and narrative regarding
selection and location of additional monitoring points should be included in the next monitoring report. We also
concur that efforts should be taken to address aggressive exotic plants in the site. Finally we believe that it is
important to continue the 2-week monitoring interval and submit data including every date point (rather than a
monthly average) in order to allow us to evaluate hydrology changes at the site over time.
Please call me at 919-733-9646 if you have any questions.
