REQUEST FOR MORE INFORMATION
Dear Mr. Allouba:
On November 13, 2009, the Division of Water Quality.(DWQ) received your minor variance application
dated November 13, 2009 to impact 266.5 square feet of Zone 2 of the protected riparian buffers to
construct the proposed 10' x 24' addition along the east side of an existing residence at the subject
property. The DWQ has determined that your application was incomplete and/or provided inaccurate
information as discussed below. The DWQ will require additional information in order to process your
application to impact protected wetlands and/or streams on the subject property. Therefore, unless we
receive five copies of the additional information requested below, we will place this project on hold as
incomplete until we receive this additional information. If we do not receive the requested information,
your project will be formally returned as incomplete. Please provide the following information so that we
may continue to review your project.
Additional Information Requested:
1. Please increase the bioretention soil media depth from 12" to 24". Depth of washed sand below
the planting soil media can be reduced.
2. Specify the Phosphorus (P) Index of the proposed soil media on the Plan.
3. This office recommends that the top surface of the outlet level spreader/overflow weir should be
flattened to evenly and uniformly distribute the excess flow along the entire 11-12 feet. Please
provide some energy dissipation measures at the bottom of the wall where the overflow occurs.
4. Please provide underdrain sizing calculations, and please note that a minimum of two (2)
underdrains are required.
5. Supplement Form: Please make the necessary corrections as follows:
a. Provide the minimum volume required and treatment volume provided;
b. Surface area at the top of the bioretention cell, and the corresponding dimensions (length
and width);
c. Change the value for the temporary pool elevation - this is the elevation of the top of the
ponding depth, or top of overflow weir/level spreader elevation.
