Re: Response to Comments —Addington Crossing Subdivision - Permit No. SW3170304
Mr. Patterson:
Carwno
Shaping the Future
Cardno is pleased to provide the attached Addendum No. 2 to the Storm Water Management Plan
for Addington Crossing Subdivision. The addendum includes a response to comments provided by
your office dated June 6, 2017. The comments from the above referenced letter have been
reproduced below and addressed as follows:
Provide the original signed deed restrictions form.
An original copy of the deed restrictions form has been provided as an attachment to this
correspondence.
Y Since you are seeking credit in Storm-EZ for the disconnected impervious areas (DIS) and
grass swales, add DIS and grass swales to the O&M Agreement and provide an original
signed form.
Based upon communication with NCDEQ staff on June 15, 2017, Storm EZ forms are no long
required for the project. LID is not being considered for the site. All the dry detention basins
have been redesigned as bio-retention basins.
i( Submit supplement forms for the DIS and treatment swales. Only the pages for the dry
ponds were submitted.
Based upon communication with NCDEQ staff supplement forms are being submitted for the
bio-retention basins only.

4. Repeat Comment - Since the project proposes handling runoff predominantly using storm
drainage piping, SCM's and is not dispersing flow, it must meet all of the high density
requirements and MDC's in the SCM Design Manual. Revise the SCM's to be from the list of
primary SCM's to treat the water quality volume (1"). Dry pools are secondarySCM's. Provide
supporting calculations for the SCM water quality designs. Even though you are attempting to
use volume matching, all SCMs used for credit in Storm EZ must meet all MDC. Provide the
following:
a. Supporting calcs for the treatment swales demonstrating all MDC are met.
b. Supporting calcs for DIS demonstrating all MDC are met.
c. Supporting calcs for the dry ponds demonstrating all MDC are met.
i. Oriface sizing for draw down for 1" storm must be between 2-5 days, not 1 day.
ii. Water quality volume calculations for t"storm
iii. Stage/storage table to show the storage volume of the 1" storm.

) Care"a
Shaping the Future
Page 2
May 25, 2017
d. Provide an on -site soils report that demonstrates the SHWT elevation for each SCM
meets the M DC.
As mentioned above, Storm EZ forms are no longer being used for the project. All dry
detention basins have been redesigned as bio-retention basins and revised calculations have
been provided. Each basin has been designed for a generated one inch rainfall across the
entire drainage basin and each basin was sized to store runoff volumes in excess of 48 hours.
Calculations for each basin include stage storage tables have been provided as an
attachment to this correspondence.
X Revise Storm-EZ as follows:
a. There is some error(s) somewhere in the data entered that is causing the rainfall fate
output errors (4div/0), even though there are DA's with treated outflow (like dry
ponds) and DA's with untreated runoff (like direct release 4). Please call to discuss.
b. The minimum design storm for this location is P90.
c. The proposed impervious areas on the project data tab need to be broken out in the
categories, buildings/lots, streets, etc.
d. The DA's are not consistent with the DA map for the swales and dry ponds.
e. Only include the project property area in the DA's in Storhh-EZ unless off -site area
actually drains into a SCM (doesn't appear to for this project). Revise the tabs for
project data, pre -development, post -development, and stormwater controls.
f. Revise the SCM tab:
DA's that do not have a SCM need to be removed
it. Treatment swales and DIS should have zero for storage volume since they
don't store runoff (they function only as filters).
iii. DA C proposes swales, so Bypass 1 area does not meet the DIS MDC.
As mentioned above, Storm EZ forms are no longer required for the project and have
therefore not been revised as requested in the comment above..
JV Revise the dry pond easements to include the entire dam embankment to the outside toe
of slope.
Although all the basins have been redesigned as bio-retention basins, all easements have
been revised to include the entirety of the basins including the outside toe of slope.
For DIS to be used, the plans need to include a note that gutters shall discharge onto the
ground, and cannot be piped.
A note has been added to the plans that all gutter systems shall discharge onto the ground
and cannot be piped below ground.
Due to the nature of the above comments, additional comments may be forthcoming once
revisions are submitted.
Noted.

The Division of Energy, Mineral, and Land Resources (DEMLR), received additional
information for the Stormwater Management Permit Application for the subject project on May
31, 2017. 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. Provide the original signed deed restrictions form.
2. Since you are seeking credit in Storm-EZ for the disconnected impervious areas (DIS)
and grass swales, add DIS and grass swales to the O&M Agreement and provide an
original signed form.
3. Submit supplement forms for the DIS and treatment swales. Only the pages for the dry
ponds were submitted.
4. Repeat Comment: Since the project proposes handling runoff predominantly using storm
drainage piping, SCM's, and is not dispersing flow, it must meet all of the high density
requirements and MDC's in the SCM Design Manual. Revise the SCM's to be from the

i. Orifice sizingfor draw down for 1 " storm must be between 2-5 days, not I
day.
ii. Water quality volume calculation for 1 " storm.
iii. Stage/storage table to show the storage volume of the I " storm.
d. Provide an on -site soils report that demonstrates the SHWT elevation for each
SCM meets the MDC.
Revise Storm-EZ as follows:
a. There is some error(s) somewhere in the data entered that is causing the rainfall
fate output errors (#div/0), even though there are DA's with treated outflow (like
dry ponds) and DA's with untreated runoff (like direct release 4). Please call to
discuss.
b. The minimum design storm for this location is P90.
C. Tho.pr*sed impervious areas on the project data tab need to be broken out in
the categories, buildings/lots, streets, etc.
d. The DA's are not consistent with the DA map for the swales and dry ponds.
e. Only include the project property area in the DA's in Storm-EZ unless off -site
area actually drains into a SCM (doesn't appear to for this project). Revise the
tabs for project data, pre -development, post -development, and stormwater
controls.
f. Revise the SCM tab:
i. DA's that do not have a SCM need to be removed
ii. Treatment swales and DIS should have zero for storage volume since they
don't store runoff (they function only as filters).
iii. DA C proposes swales, so Bypass I area does not meet the DIS MDC.
6. Revise the dry pond easements to include the entire dam embankment to the outside toe
of slope.
7. For DIS to be used, the plans need to include a note that gutters shall discharge onto the
ground, and cannot be piped.
8. Due to the nature of the above comments, additional comments may be forthcoming once
revisions are submitted.
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 June 20, 2017, or the
application will be returned as incomplete. The return of a project will necessitate resubmittal of
all required items, including the application fee.
If you need additional time to submit the information, please submit your request for a time
extension to the Division at the contact below. The request must indicate the date by which you
expect to submit the required information. The Division is allowed 90 days from the receipt of
a completed application to issue the permit.
The construction of any impervious surfaces, other than a construction entrance under an
approved Sedimentation Erosion Control Plan, is a violation ofNCGS 143-215.1 and is subject
to enforcement action pursuant to NCGS 143-215.6A.

Wesley Chapel, North Carolina
Dear Mr. Cash:
Based on ATC's review of the Preliminary Geotechnical Report prepared by others and dated February 10,
2016, our review of the area topographical map, and our experience in the Piedmont area of North
Carolina, we provide the below Estimated Seasonal Water Table Elevations for the proposed Detention
Ponds planned for the site.

Dim, to,
The Division of Energy, Mineral, and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on March 20, 2017. 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. Please provide a copy of the JD from USACE.
2. On SWU-I01 item IV.10, complete the table with all DA and impervious area
information.
3. The person signing the applications, deed restrictions, and O&M agreement must bean
officer of the company as listed on the NC Sec. of State's website. Or provide a signed
letter for one the officers listed giving Brian Johnson signature authority.
Remove the "Preliminary — Not for Construction" note on the plans. Plans for the permit
must be final plans.
5. Fill-in the max BUA for each lot on the deed restrictions form.
6. The O&M Agreement is missing pages that show the maintenance table and SCM
maintenance details.
7. Since the project proposes handling runoff predominantly using storm drainage piping,
SCM's, and is not dispersing flow, it must meet all of the high density requirements and
MDC's in the SCM Design Manual and the revise 2017 rules. Revise the SCM's to be
