REQUEST FOR MORE INFORMATION
Dear Mr. Beuley:
DWQ EXP # 08-0965v3
Lincoln County
On February 24, 2009, the Express Review Program of the Division of Water Quality (DWQ) received
your Stormwater Managemnt Plan Application for the above referenced project. 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 and prevent return of your application as
required by 15A NCAC 2H .0506:
Additional Information Requested
1. All Wet Ponds:
a. The normal (permanent) pool elevation shall be located in the midsection of the 10-foot
vegetated shelf such that the bottom 6 inches of the shelf will be permanently under water
while the top half will be occasionally inundated by stormwater runoff.
b. Determining the required surface area of a wet pond is an iterative process (one iteration
typical, after initial trial depth). Please use the average depth as computed on the supplement
form to determine the surface area-to-drainage area (SA/DA) ratio from the table, and
subsequently compute the required surface area. Using this process and the information
provided, Wet Pond 1 was found to be inadequately sized. You may increase the surface area
or pond depth.
c. Planting Plan: The plants schedule table on Sheet SWMP L1 needs to be revised. Wet Pond 2
has been repeated (instead of Wet Pond 3), and the total of individual plants do not match the
sum of plants from all three wet ponds.
d. This office recommends the use of plunge pool (rip rap basin) at the BMP pipe outlet instead
of the flat rip rap apron to further reduce pipe outlet velocities.
e. The geotechnical report indicates Silty Fine Sand soils within 10.0 feet from the ground
surface at most locations especially where the ponds are located. Please specify on the plans
that the bottom and sides of the ponds shall be compacted, or constructed of clayey material
to maintain the normal pool by preventing the water from quickly draining into the soil.
