Stormwater Permit No. SW6210102 (Formerly SW6190802)
Four Sierra Ranch
Cumberland County
Dear Mr. Nobles:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project ohr January 25, 2021. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
NOTE: This project was reviewed under the assumption that it will be a low -density
project. If this changes (either to high -density or mixed density) please let me know as
the comments will change. Low -density projects do not require the use of SCMs to meet
treatment requirements so the proposed infiltration basin was not reviewed for
compliance with the MDCs and will not be included as an enforceable part of the final
permit. The permit will contain language stating that the proposed infiltration basin exists
on -site, but is not associated with/subject to the post -construction permit (I can provide
you with the specific language if you like).
1. Please correct the following items in order to make this into a low -density submission:
a. Section IV,1 of the Application — Please add a note to the project summary stating
that the proposed infiltration basin is not required for compliance with the post -
construction permit. i,Joe aI ldcd, cv�scA flicet
b. O&M Agreement Form — Please complete and resubmit the latest version of this
form (which can be found at the following link:
https:// e_q nc. ova o�t�divisions/mart, � -mine rah ary lardy,

resources/stormwater/storrnwater-o r stormwat Ldest n). The latest version
of this form contains an option for "low -density" and this option should be
selected. You may, if you choose, add the infiltration basin to the O&M

infiltration basin is not required for compliance with the post -construction permit
(Can place it in the "Location(s)" section of the cover page).
Supplement-EZ Form — Like the O&M Agreement Form, there is a newer version
of this form that should be used that includes low -density options (Can be found

i. Cover Page:
1. Line 5 — Please select "Low" for the project density.
2. Line 11 — Since the infiltration system is not needed for the post -
construction permit, this value should be "0".
ii. Drainage Areas Page:
1. Line 1 — This is not a high -density project so the answer should be
«NO
2. Drainage Area 1 Column — This information is not needed.
3. Entire Site Column — Lines 17-19 (Design Storm, Design Volume,
and Calculation Method) are not needed.
iii. Low -Density Page — Please include this page. Each separate vegetated
conveyance should get its own line and the information should match that
shown in the calculations. viffi sup n�uit.W,
d. Deed Restriction Form — Please complete and resubmit the Low -Density
Residential Subdivision Deed Restriction Form (Link to the form:
htt s.://ale nc... o about/divisions/ener gy.-.mineral-and-land-
.resources/sto water/stp waterpprogril n st-construction-1). For item 6 (Max.
BUA per lot), please use the second option where the maximum BUA per lot is
listed on a per -lot basis (Since lot 7 has zero square feet of BUA allocated to it).
For example, you can say "Lots 1-6 & 8-14 = 4,500 sf' and "Lot 7 = 0 sf' (Each
individual lot does not need its own separate line). �,rune^ 'i'"i'orii'i°inn u,.�S.?(i, L. pdatu�N:��� as u"" ot: ed
2. Please provide a USGS topographic map clearly showing the extent of the project area
(Section VI, 6). NOTE: The maps in the stormwater report exclude lots 1-4 & lots 12-14
from the project area.'^/;°a
3. Please provide time of concentration (Tc) calculations for the proposed vegetated
conveyances so the calculations may be verified (Section VI, 7).
