The Pavilion at Carolina Beach
High Density Stormwater Project
New Hanover County
Dear Mr. Saieed:
The Wilmington Regional Office received a complete Stormwater Management Permit
Application for The Pavilion at Carolina Beach on June 3, 2004. 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 2H.1000. We are forwarding Permit No. SWS 040522
dated June 3, 2004, for the construction of The Pavilion at Carolina Beach.
This permit shall be effective from the date of issuance until June 3, 2014, and shall be
subject to the conditions and limitations as specified therein. 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.
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 Hearings, P.O. Drawer27447, Raleigh, NC 27611-7447. Unless such demands
are made this permit shall be final and binding.
If you have any questions, or need additional information concerning this matter, please
contact Laurie Munn, or me at [phone].
Sincerely,

4. All stormwater collection and treatment systems must be located in either dedicated
common areas or recorded easements. The final plats for the project will be recorded
showing all such required easements, in accordance with the approved plans.
a. The runoff from all built -upon area within the permitted drainage area of this project must
be directed into the permitted stormwater control system. A permit modification must be
submitted and approved prior to the construction of additional built -upon area from
outside of the approved drainage area.

Section: 15 A NCAC 2H .1008.
Initial in the space provided to indicate the following design requirements have been met and supporting
documentation is attached. If the applicant has designated an agent in the Stormwater Management Permit
Application Form, the agent may initial below. If a requirement has not been met, attach justification.
Applicants Initials
a. System is located 50 feet from class SA waters and 30 feet from other surface waters.
_ b. System is located at least 100 feet from water supply wells.
c. Bottom of system is at least 2 feet above the seasonal high water table.
SPZ d. Bottom of the system is 3 feet above any bedrock or impervious soil horizon.
NIA e. Off-line system, runoff in excess of the design volume bypasses the system (bypass detail
provided). ,tt 0( lt*' v1 Cive*ty
f.
System is designed to draw down the design storage volume to the proposed bottom
elevation under seasonal high water conditions within five days based upon infiltration
through the bottom only (a hydrogeologic evaluation may be required).
SMg.
Soils have a minimum hydraulic conductivity of 0.52 inches per hour.
h.
System is not sited on or in fill material or DWQ approval has been obtained.
T5f
Sf i.
Plans ensure that the installed system will meet design specifications (constructed or
restored) upon initial operation once the project is complete and the entire drainage area is
stabilized.
SQ j.
System is sized to take into account the runoff at the ultimate built -out potential from all
D
surfaces draining to the system, including any off -site drainage.
SDf k.
System is located in a recorded drainage easement for the purposes of operation and
maintenance and has recorded access easements to the nearest public right-of-way.
I.
System capture and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event
for areas draining to SA waters).
c(!f
m. Drainage area for the device is less than 5 acres.
n. A pretreatment device (filter strip, grassed swale, sediment trap, etc.) is provided.
o. Trench bottom is covered with a layer of clean sand to an average depth of 4 inches.

s. Observation well(s) are provided (case -by -case basis).
t. Vegetated filter is provided for overflow (50 feet for SA waters, 30 feet for other waters)
and detail is shown on plans.
u. A benchmark for checking sediment accumulation is provided.
IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
l . After every runoff producing rainfall event and at least monthly inspect the bypass/overflow structure for
blockage and deterioration and the infiltration system for erosion, trash accumulation, grass cover, and general
condition.
2. Repair eroded areas immediately, re -seed as necessary to maintain adequate vegetative cover, mow vegetated
cover to maintain a maximum height of six -inches, and remove trash as needed.
3. Remove accumulated sediment annually or when depth is reduced to 75% of the original design depth. Restore
depth to original design depth without over -excavating. Over -excavating may cause the required water table
separation to be reduced and may compromise the ability of the system to perform as designed.
4. The water level in any monitoring wells will be recorded after a I inch rainfall event and at least once a
month. Chronic high water table elevations (within I foot of the bottom of the system for a period of three
months) shall be reported to DWQ immediately.
5. if DWQ determines that the system is failing, the system will immediately be repaired or replaced to original
design specifications. If the system cannot be repaired to perform its design function, other stormwater control
devices as allowed by NCAC 2H .1000 must be designed, approved and constructed.
6. Remove accumulated sediment from the infiltration system annually or when depth in the unit is reduced
to 75% of the original design depth. The system shall be restored to the original design depth without
over -excavating. Over excavating may cause the required water table separation to be reduced and may
compromise the ability of the system to perform as designed. 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 stormwater treatment device or stream, etc.).
A benchmark shall be established in the infiltration system. The benchmark will document the original
design depth so that accurate sediment accumulation readings can be taken. The measuring device used to
determine the depth at the benchmark shall be such that it will give an accurate depth reading and not
readily penetrate into accumulated sediments.
When the depth at the benchmark reads 3.62 FT* , the accumulated sediment shall be removed
from the system.
* Benchmark is top of inlet #1.

collection system in accordance with the six maintenance procedures listed above. I agree to notify DWQ of
any problems with the system or prior to any changes to the system or responsible party.
