Subject: RE: [External] RE: SW6230102 Tranquil Meadows Phase 1 Request for Information
Good morning, Jeff,
I was looking over the information you provided on May 08, 2023. Everything looks good except for a few small issues:
Please provide 2x signed & sealed hard copies of plan sheets showing the following:
1. Please delineate the drainage area going to Wet Basin 1 in the Drainage Plan and note the area in square feet on the plans corresponding to the value listed
in the Application Section IV, 10 Drainage Area. This is required per 15A NCAC 02H .1042(2)(g)(iv) & Section VI, 8o of the Application). The drainage areas
map was submitted with the original plans submittal. The drainage area to Wet Basin 1 has not changed. I have updated the map with the current phase
lines for clarification.
2. Please revise the notes on the plans for consistency. Forebay overflow weir top width in the cross section is 5', on the plan view, the forebay overflow weir
specifies a minimum of 10' wide. The two dimensions are referencing different things. The 5' dimension on the cross section is the width at the top of the
forebay berm. The 10' dimension is the width of the opening of the forebay overflow weir.
3. Supplement-EZ, Wet Pond Line 48 indicates Bermuda turf (or another kind of non -clumping turf, if you wish to update the Supplement-EZ) will be used on
the dam and embankment, please specify on the plans. A note has been added to the Wet Basin 1 Detail sheet.
Please provide 1x hard copy of the complete, original Supplement-EZ Form with the following corrections made (This item is required per Sections V & Vl, 3 of the
Application):
1) Wet Pond: Line 2 — Please revise the minimum required treatment volume in Line 2 to match the calculated volume. The calculation provided is correct
based on the actual numbers calculated for A and Rd. These are calculated numbers that were only carried to 2 significant figures. The WQV calculation is
based on the actual calculated values of A (20.8640495868 ac) and Rd (0.418716207).
Per the provided calculations:
V=3630*Rd*Rv*A
Rd=1 in, Rv = 0.42, A=20.86
V=3630*1 in*0.42*20.86=31,803 cf
Provide PDFs of all revisions, 2 hardcopies of revised plan sheets, 1 hardcopy of other documents.
Hard copies must be mailed or delivered to the following address:
For FedEx/UPS:
Brianna Holland
512 N. Salisbury Street, Office 640E
Raleigh, NC 27604
For USPS:

Hand Delivery:
Please reach out to me prior to hand delivering a submission to make sure that I (or someone else in my group) will be able to receive the submission. Do not leave the
package in the foyer with the security guard.
NOTE: Hard copies should not be sent to a Regional Office. Doing so will delay the review process and the submission package may be lost while being sent from the
Regional Office to me in the Central Office.
While not required, consider revising the hatch pattern or outlining the hatch, the bottom elevation is no longer visible, which makes it less apparent on the cross
section that the weir has been raised to the temporary pool elevation. Hatching has been updated for clarity.
Electronic copies should be uploaded at the following location:
https:/iedocs.deg.nc.gov/Forms/sw-sgpple )w • at -Upload
Since these are really minor things, once I get the hard copies, anything else that may have changed from addressing these issues, and the documents are uploaded to
Laserfiche (Provided everything is still in order), we can issue the permit without doing another formal review.
Let me know if you have any questions.
