Subject: State Stormwater Management Permit No. SW8 960818 Mod.
Jungle Rapids
High Density Commercial Project
New Hanover County
Dear Mr. Rippy:
The Wilmington Regional Office received a complete modified Stormwater Management
Permit Application for Jungle Rapids on November 15, 2012. Staff review of the plans
and specifications has determined that the project, as proposed, will comply with the
Stormwater Regulations set forth in Title 15A NCAC 21-11.1000. We are forwarding
modified Permit No. SW8 960818, dated December 4, 2012, for the construction of the
subject project.
The modifications covered by this permit include the following:
1. Relocating the outlet structure to provide better drainage on Brenda Drive.
2. Accounting for additional offsite drainage that had not been included previously.
3. Raising the permanent pool elevation to 16.3 fmsl.
4. Raising the temporary pool elevation to 17.8 fmsl.
5. The City is undertaking the work of modifying the pond as part of the Brenda Drive
Drainage Improvement project.
On August 5, 2009, the Governor signed Session Law 2009-406. This law impacts any
development approval issued by the Division of Water Quality under Article 21 of
Chapter 143 of the General Statutes, which is current and valid at any point between
January 1, 2008, and December 31, 2010. The law extends the effective period of any
stormwater permit that is 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 grants an extra year for a total of four (4) years extension. Please note that
the expiration date of this permit has been adjusted to reflect this four year extension.
This permit shall be effective from the date of issuance until November 19, 2023, and
shall be 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), certification of the BMP's, procedures for changing
ownership, transferring the permit, and renewing the permit. Failure to establish an
adequate system for operation and maintenance of the stormwater management
system, to certify the BMP's, to transfer the permit, or to renew the permit, will result in
future compliance problems.

As the legal property owner I acknowledge, understand, and agree by my signature below, that if my designated
agent (entity listed in Contact Information, item 1) dissolves their company and/or cancels or defaults on their
lease agreement, or pending sale, responsibility for compliance with the DWQ Stormwater permit reverts back to
me, the property owner. As the property owner, it is my responsibility to notify DWQ immediately and submit a
completed Name/Ownership Change Form within 30 days; otherwise I will be operating a stormwater treatment
facility without a valid permit. I understand that the operation of a stormwater treatment facility without a valid
permit is a violation of NC General Statue 143-215.1 and may result in appropriate enforcement action including
the assessment of civil penalties of up to $25,000 per day, pursuant to NCGS 143-215.6.

1 When using the Division SA/DA tables, the correct SA/DA ratio for permanent pool sizing should be computed based upon the
actual impervious % and permanent pool depth. Linear interpolation should be employed to determine the correct value for non-
standard table entries.
2 The requirement for a vegetative filter may be waived if the wet detention basin is designed to meet 90% TSS removal.
3 The legally responsible party should not be a homeowners association unless more than 50% of the lots have been sold and a
resident of the subdivision has been named the president.
III. WET DETENTION BASIN OPERATION AND MAINTENANCE AGREEMENT
The wet detention basin system is defined as the wet detention basin, forebay, non-integrated pretreatment
systems (pretreatment other than forebays), and the vegetated filter if one is provided.
This system (check one) ❑ does IR does not incorporate a vegetated filter.
This system (check one) 11 does E does not incorporate non-integrated pretreatment.
Maintenance activities shall be performs as follows:
1. After every significant runoff producing rainfall event and at least monthly:
Form SWU-102 Rev 1/August 1998 Page 2 of 3

f
` a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation, grass
cover, and general condition.
b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within
2 to 5 days.
2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six inches, and remove trash as needed,
3. Inspect and repair the collection system (i.e. catch basins, piping, swales,
proper functioning. riprap, etc.) quarterly to maintain
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth. Removed sediment shall be disposed of in an appropriate
manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a
wet detention basin or stream, etc.).
The on (
original design depth is: 10.0 Ms ]: (f / l
The sediment removal benchmark depth is: 14.5 ms 1 44.
5. Remove cattails and other indigenous wetland plants when they cover 75% of the basin surface. These
plants shall be encouraged to grow along the basin perimeter.
6. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through
the emergency drain shall be minimized to the maximum extent practical.
7. All components of the wet detention basin system shall be maintained in good working order.
I acknowledge and agree by my signature below that I am responsible for the performance of the above
maintenance procedures. I agree to notify DWQ of any problems with the Mtem or changes in the name of the
