Sue,
I told them to keep the stormwater outlets away from the buffer areas and provide vegetative swales to discharge into
the buffer. The attached plans look fine to me but I would like for you to include the visual monitoring requirement in
their 401 certification (for all the SW outlets, swales, and the discharging points into the buffer). I think monitor them for
2 years is sufficient unless we found some issues during the monitoring period.
Thanks!

Good Morning Ms. McDaniel
I have attached our swale design for the Quarry Hills subdivision. Each swale is shown in red and the swale calculations
are in a red box generally in the top center or top left of each sheet. Please let me know if you have any questions or if
you need additional info. Thanks for your consideration.

I have attached pdfs showing the pipe outlets for this project being located greater than 100' away from the buffers as
we discussed. I would like for you to review this in concept prior to us providing design for the vegetated channels from
these pipe outlets to the buffers. Give me a call to discuss. Thanks for your help.

Anthony,
Per our phone conversation earlier, attached file is the stormwater conveyance design requirements for low density
projects. I highlighted the items that are applicable to your project. The curb and gutter design criteria is under Item
(2)(d)•
Here is the link to DEMLR's BMP design manual (level spreader is under C-9):
https://deg.nc.gov/about/divisions/energy-mineral-land-resources/energy-mineral-land-permit-guidance/stormwater-
bmp-manual
Also, NCDOT has some useful design ideas and information for their lever spreader, preformed scour hole, and dry basin
(https://connect.ncdot.gov/resources/hydro/HSPDocuments/2014 BMP Toolbox.pdf). Look under Chapters 3 through
5.
One thing I want to point out to you, the buffer rules require that concentrated runoff be converted to diffuse flow
before the runoff enters the Zone 2 of the riparian buffer. This is how providing grass swales and vegetated areas prior
to entering the buffer zone can help you meet this requirement. If there are some critical areas where this cannot be
met, you will need to provide justification for the proposed outlet location. Additional measure(s) may be provided to
ensure non -erosive discharge and protection of the receiving stream.

The first pdf is the approved master plan for the entire subdivision. The second pdf is of the Phase 1 East Side storm
drainage plan and the third pdf is of the Phase 1 West Side storm drainage plan. Phase 1 is what we are trying to build
now and is what was submitted to Sue. Please call to discuss after you have reviewed.

The file attached to your email is DEQ's add.info request letter. I don't see any copies of the phase 1 storm drain plans
nor the approved overall plans that you mentioned. Can you resend those files to me please. Thank you.

Good Morning Chonticha
I am currently working together with Sue Homewood on a project in Swepsonville, NC. Please see her email below. This
project has several pipe outlets in Phase 1 that we may or may not need to provide dispersed flow at the outlet. I have
attached copies of the phase 1 storm drain plans as well as the approved overall plans. After reviewing the below email
and the attached plans, please call me so that we can discuss where and where not we are to provide dispersed
flow. My contact info is below:

Anthony & Brad,
As we discussed on the phone recently, this project is in the unique situation of being within a local government (Town
of Swepsonville) jurisdiction for the Phase 11 stormwater program but within DWR jurisdiction for the implementation of

the Jordan Lake Riparian Buffer Rules. This unique situation only happens in a couple small locations within the Jordan
Watershed but it is pretty common in the Neuse watershed so we've been dealing with it for years. Item (8) of the
Jordan Buffer Rules requires that "diffuse flow of runoff shall be maintained in the riparian buffer by dispersing
concentrated flow prior to its entry into the buffer". That is why I requested a set of plans that shows diffuse flow will be
met for the project. Here's a memo that explains what meets the definition of diffuse flow.
As I mentioned, Chonticha McDaniel is our 401 stormwater engineer and will be the one who reviews the diffuse
plans. I've copied her on this email so she knows about the project. You can copy her when you submit your response
to the addinfo letter, that way she'll have a copy of the stormwater info as soon as possible. Here's her contact info:
