REQUEST FOR MORE INFORMATION-EXPRESS REVIEW PROGRAM
On April 16, 2007, the Division of Water Quality (DWQ) received information requested in order to be
able to review your March 27, 2007 application for the E22 Access Road/Wake County schools site. The
DWQ has determined that your application will require additional information. Please provide the
following information so that we may continue to review your project:
1. Stormwater Management Plan:
a) The planting plan for Extended Detention Wetland No. 1 contains a number of errors.
I. Please note that some of your common names and scientific names do not coincide and that
your indicator statuses are wrong for many plants on both Table 2 and Table 4. Of note,
New York Ironweed is FAC+, Panicgrass is FAC+, and Wild celery is FAC (Zone B
only!). Additionally, the American water plantain (Alisma subcordatum) is an alternative
to planting the European water•plantain (Alisma plantago-aquatica); they are both OBL.
II. Table 4: Please note that all the indicator statuses in this table are incorrect, with the
exception of Big bluestem (Andropogon girardii). Additionally, a seed mix for wetlands
should not include plants that have a drier than FAC status such as (FAC-, FACU, UPL)
unless you are planting in the upland fringe of the wetland.
III. A helpful Internet site to review plant status information is http://plants.usda.gov/ -North
Carolina is in Region 2.
N. Finally, please use a standard planting plan format that includes the number of plants,
planting key for each zone within the wetland, spacing, size, and source of the plant.
material. Instructing a landscape contractor to select a minimum of 10 species is too vague.
The planting plans should be prepared by a qualified professional.
b) The drainage area of 1.67 acres for Extended Detention Wetland No. 2 is too small. DWQ does not
recommend this stormwater best management practice for drainage areas under five (5) acres.
Please redesign for a bioretention cell and include an appropriate planting plan and operation and
maintenance agreement for this stormwater structure.
Please respond within three (3) days of the date of this letter by sending three (3) copies of this
information. The Express Review Program is a process that requires all parties to participate in a timely
manner. You are reminded that the clock for this Express Review Project ends on Apri127, 2007. If you
have not been able to resolve the issues within this timeframe, then you will be required to reapply to the
regular 401 Water Quality Certification program and those required application fees. If the DWQ feels
