RE: 2S - DWR# 2010-0899 v3
1. A SMP that includes a complete final design to accommodate the final build out impervious area, 2S and 3S, or
2. A SMP that includes a final design for treatment of all impervious surfaces proposed in Phase 2S and a
conceptual design for all future impervious surfaces in Phase 3S. The purpose of the conceptual design for
future phases is to determine the approximate size and location of future SCMs to ensure that they will not
require impacts to streams or wetlands.
If Option 2 is chosen then the 401 certification will have a condition that a final SMP must be submitted and approved
prior to any new impervious surfaces being added in Phase 3S.
One final note, since you'll be doing final grading at this time. If any stormwater collection pipes are installed during the
grading phase you will either need to find a means of blocking them off, or the SMP for Phase 2S will need to account for
the flow from the graded areas.
Please let me know if you have any follow up questions.
Thanks,

Sue,
Attached are our latest preliminary Overall Site Plans which should help to provide clarity regarding what is 2S and what
is future 3S built -upon -area.
I've highlighted in blue what will be the future 3S built -upon -areas. Any work on these future areas would likely be years
down the road, and they will only be rough -graded and leveled at this time.
Let me know how this might impact your response below.
Thanks,
Micha

Micha,
We can probably handle any of the scenarios you describe, it will mostly likely be a business decision which to
pursue/submit. I'm not clear as to what is 2S versus 3S with regards to the set of plans that were submitted for the
404/401 application. Clement, could you clarify this for me so that I can give some more detailed advice w.r.t. the SMP
submittal.
I'll be in a meeting all day today but will be in the office tomorrow and Friday.
Thanks,

Hi Sue,
The storm water infrastructure for 2S (piping/channels/wet-ponds/etc.) will be sized to accommodate the future 3S site,
but the site won't have the built -upon -area for 3S provided at this time.
What should be the design basis demonstrated in our SMP for permitting purposes:
Analysis of the project site as it will be constructed at this time (no future 3S built -upon -area included in the
analysis)? Then, when 3S is permitted in the future it will acquire its own storm water permit at that time.
Analysis of the project site with limits of future 3S built -upon -area included in the analysis?
Analysis to include both 1 and 2 above?
My inclination is that #1 is the required design basis to be demonstrated in the SMP, and we would do our own
calculations to confirm that 3S will have capacity provided in the storm water infrastructure. But, I just wanted to
confirm.
Thanks,
Micha

Hi Micha,
Parts A-1 and A-2 aren't available yet, but Part B has guidance on volume calculations and should be everything you
need to properly size SCMs.
If you look towards the top of the stormwater webpage you'll see a link to Supplement -EZ forms and O&M -EZ forms,
those links will have all the forms you need to fill out. Please ensure that everything itemized on the supplement form is
shown/identified in the plans and/or calculations that you submit.
With regards to grading, DWR has no authority to determine what your client does on high ground in advance of
receiving the permits to disturb streams and wetlands. Any grading activity is done at the risk that changes to the
site/design may be required through the 404/401 review process. No impacts to streams or wetlands and no built upon
areas (as defined by 15A NCAC 02H .1002) may be added without final 404 & 401 approvals.
I'll be in the field the rest of this week but will be in the office most of next week if you have follow up questions.

Thanks,

Hi Sue,
I'm working on the 2S project in Shelby with Brian Hoaglund and Clement Riddle and have a few questions when you
have a moment. I'll be the civil engineer for detailed engineering. I've attached your Request for Additional Information
as a reference.
1. Would you be able to provide copies of Sections A-1 and A-2 of the new Stormwater Manual due out on 3/31?
2. We would like to actively pursue a rough grading package in order to commence earthwork on the project as
soon as possible. No impervious area would be proposed and we would not disturb the streams/wetlands as
part of the rough grade. A finished grading civil package would then be developed later and not commenced
until approval of the 401/404 permits.
a. Would the rough grading as described above only fall under the jurisdiction of DEMLR in regards to
erosion control, or would a stormwater review be required as well?
b. Where can I find location of the applicable setbacks from the streams and wetlands?
c. What if we decide to proceed with addition of some minor impervious area (e.g., graded aggregate
construction access roads and initial foundation work in limited areas)?
d. We'll be meeting with the City of Shelby to discuss the rough grade and permitting early next week.
3. Regarding Comment #8, SMP: Clement mentioned tome following his discussion with you that we are to follow
a set of checklists/spreadsheets for the BMPs we intend to employ. Where can I find this information? Sections
A-1 and A-2? Or, is this the Minimum Design Criteria in Part C that you are referring to? We will likely be
proposing the use of Wet Ponds for the project given the large drainage basins.
Feel free to give me a call to discuss, or respond via email. My contact info is below.
Thanks,
Micha
