Request
Good morning Heiko.
I have reviewed the additional information that we received January 24, 2012. There is still one item that needs
correcting; item 4 from my January 10, 2012 letter. The revised plans state a media depth in the biroretention cells as
24" with shrub/mulch. As stated in my letter, the minimum media depth for a shrub/mulch cell is 36". In order to use a
24" depth, the cell must only be planted with grass sod. Refer to chapter 12 in the BMP Manual for more information.
Please submit the requested information by February 10, 2012. Let me know if you have any questions about this
matter.
Thanks

Robert,
We are just about finished with the revised comments that you sent on January 10, 2011 and wanted to see if the
attached groundwater revision to the geotechnical report would suffice for comment 2?
We wanted to make sure before we resubmitted and did not.
Thank you so much for you help,

Hello Ms. Morgan,
We are proposing two bioretention basins on this 24/7 Child Development project and according to comment #6 (see
attached comment letter) we need to get a written verification from you that there are no issues with this project
related to any DWM regulated site or features.
The site is located at the southwest corner of the intersection of Reilly Street and Wac Street, on Fort Bragg, NC. The
project number is PN74422.
Please let me know if you need anything else. Thank you very much.

The plans and geotechnical report have been modified to respond to your comments from January 10"', 2012.
Comment 1: Sheet 1 I (bioretention cell landscape plan) needs to be sealed, signed, and dated by an appropriate NC
design professional.
✓ Response: The bioretention cell landscape plan (Sheet 11) has been signed an! sealed by a North Carolina design
professional engineer.
Comment 2: The submitted geotech report submitted does not include a specific S1-1WT elevation determination based
on mottling of the soil. "Phis must be done for each proposed cell. The information included only talks about apparent
water table during the borings.
"Response: The geotechnical report has been modified to include the information abo►tt the Season High Water
Table on pages 3-4. The whole geotechnical report was reprinted for your records.
Comment 3: Please specify double or triple shredded hardwood mulch for the bioretention cells.
Response: Double shredded hardwood mulch was labeled on sheets 04 and 11.
Comment 4: Since both cells proposed are shrub/mulch cells, a minimum of 36" of media must be used. Please revise
,ht. 4 accordingly to not say 24"-36" of media.
A Response: The plantings were reviser! to allow a depth of 24"on sheet 04.
Comment 5: The overflow from bioretention cell #2 appears to flow directly into cell #1. Ideally, the overflow should
be routed around/away from cell #l. Please explain.
ti,., Response: The reasons for this are the constraints imposed by the site. We originally proposed putting a couple of
bioretention cells on the south side of the site, but the testing that was done indicated that they mould not infiltrate.
Therefbre, we ended up moving the cells to their current locations. Another constraint is that there is no existing
burgessniple.com
January 23, 2012
Page 2
storm drainage system in the vicinity that will allow us to provide an overflow structure with an outlet pipe. This
constraint required that we use emergency spillways. Finally, the site naturally drains front west to east. 6Ye do
toot see a rvay to drain cell #2 w/o it draining; through cell V. Please note that both cells are designed to in
accordance with EISA to infiltrate the 1.8 inch or 95''' percentile storm, which is more stringent that the I inch
storm required by NCDENR. Therefore the need to bypass the flows will be infrequent.
Comment 6: With infiltration proposed (no underdrains in the biorctention cells) at Fort Bragg, please provide written
verification from Marti Morgan, at the Division of' Waste Management (DWM), that there are not any issues with this
project in relation to any DWM regulated sites or features. You can contact Mrs. Morgan via email or phone at
martha.nu>rg-,in,Li�ncdenr. y or 919-508-8447.
V Response: Ms. Morgan was contacted via entail and the attached email is verification that there are too known
environmental issues at the proposer! site.
We look forward to the approved stormwater permit. We thank you for your assistance and availability in answering
questions related to this project.
Sincerely,

Secretary
The Division of Water Quality Central Office received a Stormwater Management Permit Application
for the subject project on December 29, 2011. A preliminary review of that information has
determined that the application is not complete. The following information is needed to continue the
stormwater review:
1. Sheet 11 (bioretention cell landscape plan) needs to be sealed, signed, and dated by an
appropriate NC design professional.
2. The submitted geotech report submitted does not include a specific SHWT elevation
determination based on mottling of the soil. This must be done for each proposed cell. The
information included only talks about apparent water table during the borings.
3. Please specify double or triple shredded hardwood mulch for the bioretention cells,
4. Since both cells proposed are shrub/mulch cells, a minimum of 36" of media must be used.
Please revise sht. 4 accordingly to not say 24"-36" of media.
5. The overflow from bioretention cell #2 appears to flow directly into cell #1. Ideally, the
overflow should be routed around/away from cell #1. Please explain.
6. With infiltration proposed (no underdrains in the bioretention cells) at Fort Bragg, please
provide written verification from Marti Morgan,. at the Division of Waste Management
(DWM), that there are not any issues with this project in relation to any DWM regulated
sites or features. You can contact Mrs. Morgan via email or phone at

Please note that this request for additional information is in response to a preliminary review. The
requested information should be received by this Office prior to February 10, 2012, or the application
will be returned as incomplete. The return of a project will necessitate resubmittal of all required
items, including the application fee.
