Dear Mr. Harris:

State Stormwater Management Permit No. SW8 930710
Crosswinds Subdivision
New Hanover County
Effective August 1, 2013 the State Stormwater program has been transferred from the Division of Water Quality
(DWQ) to the Division of Energy, Mineral and Land Resources (DEMLR). All previous references to DWQ will
remain in older stormwater permits issued prior to August 1, 2013 until they are modified. Please note that this permit
will now reference DEMLR as the Division responsible for issuance of the permit.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacted any development approval issued
by the former Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which was current
and valid at any point between January 1, 2008, and December 31, 2010. The law extended the effective period of any
stormwater permit that was set to expire during this time frame to three (3) years from its current expiration date. On
August 2, 2010, the Governor signed Session Law 2010-177, which granted an extra year for a total of four (4) years
extension.
The Wilmington Regional Office received a complete 8 year Stormwater Management Permit Renewal Application for
the subject project on May 8, 2020. The Division is hereby notifying you that permit SW8 930710 has been renewed on
August 6, 2020, and shall be effective until December 6, 2032, which includes all available extensions. For your
records, please find enclosed a renewed, updated, and re -issued permit and a copy of the renewal application. As
requested, a copy of the current operation and maintenance agreement is enclosed. Please keep this permit on file at all
times. Please note that the renewed, updated, and re -issued permit does not impose new or different terms; it merely
restates some of the previous terms to provide you with a better understanding of your obligations under the permit.
The renewal and reissuance of this stormwater permit does not imply that the site is currently in compliance with the
terms and conditions of this state stormwater permit. The plans originally approved on August 23, 1993 and most
recently modified on December 6, 2010, will remain in full force and effect in accordance with the regulations set forth
in Title 15A NCAC 2H.1000.
This permit is subject to the conditions and limitations as specified therein. Please pay special attention to the
conditions listed in this permit regarding the Operation and Maintenance of the BMP(s), recordation of deed
restrictions, procedures for changes of ownership, transferring the permit, and renewing the permit. Failure to establish
an adequate system for operation and maintenance of the stormwater management system, to record deed restrictions,
to transfer the permit, or to renew the permit, will result in future compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an
adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH). The written
petition must conform to Chapter 1508 of the North Carolina General Statutes, and must be filed with the OAH within
thirty (30) days of receipt of this permit. You should contact the OAH with all questions regarding the filing. fee (if a
filing fee is required) and/or the details of the filing process at 6714 Mail Service Center, Raleigh, NC 27699-6714, or
via telephone at 919-431-3000, or visit their website at www.NCOAH.com. Unless such demands are made this permit
shall be final and binding.

for maintaining compliance with the permitted BUA limits.
4. The Director may notify the permittee when the permitted site does not meet one or more of
the minimum requirements of the permit. Within the time frame specified in the notice, the

OPERATION AND MAINTENANCE PLAN
STORMWATER DETENTION PLAN
CROSSWINDS SECTION 4
I. DESCRIPTION
A detention pored is provided to improve water quality
of the st.ormwater to be. discharged to <a drainage ditch
flowing under Mohican Trail and e-ventu;�,lly tc_, Whiskey Creek.
Tlj%, pond is designs-d, to detain tic first inch of rainfall
from existing orosswint s ,.r t ' c d Sect' �n� and prc,posed Section
4, the eastern portion of Crosswinds South, as well as,
future phases long enough for pollutants and sediment to
settle out. All of the stormw +te:r enters the detention
ponds via existing grass -lined ditches. This provides
additional opportunity for particulate matter to settle out.
Curbs and gutters have also been or will be provided in all
sections of Crosswinds to direct runoff from the roadways
into the collection systems. Crosswinds Section 1 was
designed prior to the State' s Density Limitations. Sec t,j.r)r,s
3 & 4, and Crosswinds South were designed under Low Density
Limitations. All future phases of Crosswinds will also be
designed in .accordance; with Low Density Limitation ThF::
total pond volume required for storage: is provided by two
detention ponds in series. The ponds are to have a normal
water level elevation of 15.7, a top of storage elevation csf
17.7, and 3:1 sideslopes.
II. MAINTENANCE
The developer and lot owners shall maintain original
sideslopes and vegetative cover during and followirig read
construction and subsequent house c-onstri.:ict.ic�n .
Sedimentation; should be expected during construction
activities. This sediment should be removed monthly and
vegetation reestablished.
For the long term, significant sedimentation is not
expected within the basins. The basins should be inspected,
cleaned, and vegetation reestablished twice a year.
Sediment should be removed when the pond depth is reduced to
less than 5 feet. If erosion or die -off occurs, damaged
areas should be regraded and reseeded immediately.
The.lot owners or Homeowner's Association will maintain
the drainage easements shown on the approved plan. The
Homeowner's Association will not allow lot owners to fill
ditches within the drainage easements nor alter the approved
flow pattern without an approved revised stormwater
certification from D.E.M.
