1. General
a. This project area appears to already be covered by permit SW6190901. You may
wish to permit this project(SW6240701) as a minor modification to SW6190901 as it
will make the permitting easier(unless there is a specific reason that you want this to
be permitted separately). Minor modifications are for modifications to a project with
no built-upon area increases or changes to the stormwater control measure design as
appears to be the case with this project. Please contact Mike Lawyer if you would
like to pursue this option and we can discuss how this will impact the project. The
minor modification form can be found at the following link:

forms/spf7-permit-minor-mod-form-20171005-final/download
RESPONSE:
Per our discussion with Mike Lawyer, the applications as submitted for this "New Permit- Off-Site
Supplement"is correct. Mike was to speak with you in regards to processing this type of application.
b. Please indicate that, in addition to being a high-density project, this project drains to
an off-site stormwater system (Section II, 2). I understand that the form says to
"select one"however both are being utilized by this project so both should be
selected.
RESPONSE: Both items have been selected.

c. Please ensure that Runoff Treatment is being met by this project(15A NCAC
02H .1002(43)). In order to meet Runoff Treatment, the net increase in BUA from
existing to proposed conditions must be captured/treated in one or more primary
SCMs and the submittal materials are unclear if there will be some areas of BUA that
are bypassed as drainage areas were not provided and the Entire Site column of the
Supplement-EZ was not completed.
RESPONSE: Drainage areas are being provided and the Entire Site Column of the Supplement-EZ
form has been completed.
d. Please indicate the project boundaries on the USGS topographic map (Section VI,
RESPONSE: Project boundary has been added to the USGS topographic map.
6). It is currently unclear if the 30' vegetated setback from the top of bank of the
stream/impoundment of the pond would be within the project area. If so,please revise
the package as needed.
RESPONSE: None of the proposed improvements will affect the top of bank of the pond.
2. Application
2x hard copies of the Application with the following corrections made (These items are
required per 15A NCAC 02H .1042(2)(a) and per Section VI, 1 of the Application):
a. Section IV, 8:
The overall percent impervious is determined by dividing the total proposed impervious area by
the total project area and multiplying by 100. Please revise.
RESPONSE: Project percent of impervious area was recalculated and changed in the application to
match Supplement-EZ form.
3. Supplement-EZ Form
lx hard copy of the complete, original Supplement-EZ Form is required per Sections V&VI, 3

a. Drainage Areas Page, Entire Site Column
The entire site column should be an accounting of all BUA located within the project area
(whether or not it drains to the off-site SCM) and the drainage area column should be an
accounting of all of the BUA located within the drainage area to the SCM. NOTE: Lines 19-21
are not required for the entire site column. NOTE: The information entered in the drainage area
column should match the information provided the Application Section IV, 10, so the
Application may need to be revised if it does not currently reflect this information.
RESPONSE: Application has been revised to match Entire Site column on the Supplement-EZ form.
4. Plans:

a. Please delineate the drainage area to the offsite SCM in the main set of plans (Section
VI, 8o).
RESPONSE: Drainage areas have been added to the Grading Plan.
b. Please identify and dimension all BUA for this project in the main set of plans (Section
VI, 8j). The information shown in the Supplement-EZ Form &Application should be
