Dear HOA President:
The Wilmington Regional Office received a complete Stormwater Management Permit Renewal
Application for Summerlin Falls on February 12, 2008. Therefore, permit SW8 940916 has been
renewed on August 20, 2009, and shall be effective until February 8, 2016. The plans previously
approved on February 8, 1996, in accordance with the regulations set forth in Title 15A NCAC
2H.1000 effective September 1, 1995, remain in full force and effect.
Please pay special attention to the Operation and Maintenance requirements in this permit.
Failure to establish an adequate system for operation and maintenance of the stormwater
management system will result in future compliance problems.
The re-issuance of this stormwater permit does not imply that the site is currently in compliance
with the terms and conditions of this state stormwater permit. Please notify this office with the
current name of the President of Summerlin Falls Homeowners Association, Inc.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory, hearing upon written request within thirty (30) days following
receipt of this permit. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes, and filed with the Office of Administrative

will be recorded showing all such required easements, in accordance with the
approved plans.
9. During construction, erosion shall be kept to a minimum and any eroded areas of
the system will be repaired immediately.
10. Upon completion of construction, prior to issuance of a Certificate of Occupancy,
and prior to operation of this permitted facility, a certification must be received

16 Deed Restrictions must be recorded which limit the built upon area per lot to the
amount as shown on the page 3 Section 1.7:
a. The following covenants are intended to ensure ongoing compliance with
State Stormwater Management Permit Number SW8 940916, as issued
by the Division of Water Quality under NCAC 2H.1000.

the extent necessary to maintain compliance with the Stormwater
Management Permit.
C. These covenants are to run with the land and be binding on all persons
and parties claiming under them.
d. The covenants pertaining to stormwater may not be altered or rescinded
without the express written consent of the State of North Carolina,
Division of Water Quality.
e. Alteration of the drainage as shown on the approved plans may not take
place without the concurrence of the Division of Water Quality.
f. The maximum built-upon area is 344,600 square feet. This allotted

reduction in their allowable built-upon area due to CAMA regulations.
h. All runoff on the lot must drain into the permitted system. This may be
accomplished through providing roof drain gutters, which drain to the
street, grading the lot to drain toward the street, or grading perimeter
swales and directing them into the pond or street. Lots that will naturally
drain into the system are not required to provide these measures.
j. Built-upon area in excess of the permitted amount will require a permit
modification.
17. A copy of the recorded deed restrictions must be submitted to the Division
within 30 days of the date of recording the plat, and prior to selling lots. The

items not in compliance must be repaired or replaced to design condition prior
to the transfer. Records of maintenance activities performed to date will be
required.

subject to the following criteria:
a. The fountain must draw its water from less than 2' below the permanent
pool surface.

deepest part of the pond.
C. The falling water from the fountain must be centered in the pond, away
from the shoreline.
d. The maximum horsepower for the fountain's pump is based on the
permanent pool volume. The maximum pump power for a fountain in this
pond is 1/6 horsepower.

Wet Detention Basin Inspection and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BMP.
The wet detention basin system is defined. as the wet detention basin,
pretreatment including forebays and the vegetated filter if one is provided.
This system (check one):
does does not incorporate a vegetated filter at the outlet.
This system (check one):
does E] does not incorporate pretreatment other than a forebay.
Important maintenance procedures:
— Immediately after the wet detention basin is established, the plants on the
vegetated shelf and perimeter of the basin should be watered twice weekly if
needed, until the plants become established (commonly six weeks).
— No portion of the wet detention pond should be fertilized after the first initial
fertilization that is required to establish the plants on the vegetated shelf.
— Stable groundcover should be maintained in the drainage area to reduce the
sediment load to the wet detention basin.
— If the basin must be drained for an emergency or to perform maintenance, the
flushing of sediment through the emergency drain should be minunized to the
maximum extent practical.
— Once a year, a dam safety expert should inspect the embankment.
After the wet detention pond is established, it should be inspected once a month and
within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a
Coastal County). Records of inspection and maintenance should be kept in a known set
location and must be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.
