Subject: Stormwater Permit Renewal & Ownership Change
Stormwater Management Permit SW7060106
Cypress Cove
Manteo, NC, Dare County
Dear Sir:
A Division of Energy, Mineral, and Land Resources file review has determined that
Stormwater Permit SW7060106 for a stormwater treatment system consisting of
infiltration basins serving Cypress Cove located on Hwy 64/264 in Manteo, NC expires
on February;6, 2020. This is a reminder that permit renewal applications are due 180
days prior to expiration. We do not have a record of receiving a renewal application.
The permit was originally issued to Skyco Development Company. It was noted in the
Currituck County tax records that the property is now owned by Cypress Cove
Homeowners' Association, Inc. Permits are not automatically transferred to new owners
without the submittal of an ownership change application and fee. Please submit a
completed permit renewal application along with a $505.00 fee for permit renewal and
an ownership change application with an additional $505.00 fee. Application forms for
renewal and ownership change can be found on our website at:
North Carolina General Statutes and the
Coastal Stormwater rules require that this property be covered under a stormwater
permit. Failure to maintain a permit subjects the owner to assessment of civil penalties.
If you have questions, please feel free to contact me at [phone]. 1 will be glad to
discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the
application forms. You can request a copy by e-mailing me at

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.
d. ;Bottom of the system is 3 feet above any bedrock or impervious soil horizon.
c. System is not sited on or in fill material or DWQ approval has been obtained.
f. System is located in a recorded drainage easement for purposes of operation and
tnaintenance and has recorded access easements to the nearest public right-of-way.
g. 'Drainage area for the device is less that 5 acres.
h. Soils have a minimum hydraulic conductivity of 0.52 inches per hour and soils report is
'attached.
i. System captures and infiltrates the runoff from the first 1.0 inch of rainfall (1.5 inch event
,for areas draining to SA waters). Design volume and infiltration calculations attached.
j. 'System is sized to take into account the runoff at the ultimate built -out potential from all
surfaces draining to the system, including any off -site drainage. Calculations attached.
If L12�4 k. All side slopes stabilized with vegetated cover are no steeper than 3:1 (H:V).
1. A pretreatment device such as a catch basin, grease trap, filter strip, grassed Swale or
sediment trap is provided.
m. Bottom of the device is covered with a layer of clean sand to an average depth of 4 inches
or dense vegetative cover is provided.

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly Inspect the nlfiltratlon system for erosion,
trash accumulation, vegetative 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. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75%, of the original design depth. The system shall be restored
to the original design depth without over -excavation. Over -excavating; may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as deigned.
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 pretreatment unit. 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 design depth reads 1.00 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired 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.
I acknowledge and agree by my signature below that I am responsible for performance of the five
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.

structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored
to the original design depth without over -excavation. Over -excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as deigned.
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 pretreatment unit. 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 sedimenleet
:./

When the design depth reads -1.00 in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired 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.
I acknowledge and agree by my signature below that I am responsible for performance of the five
maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any

IV. INFILTRATION BASIN OPERATION AND MAINTENANCE AGREEMENT
1. After every runoff producing rainfall event and at least monthly inspect the infiltration system for erosion,
trash accumulation, vegetative 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. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored
to the original design depth without over -excavation. Over -excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as deigned.
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 pretreatment unit. 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 design depth reads 1.00 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired 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.
I acknowledge and agree by my signature below that I am responsible for performance of the five
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.

vegetated cover to maintain a maximum height of six inches, and remove trash as needed
3. After every runoff producing rainfall event and at least monthly inspect the bypass, inflow and overflow
structures for blockage and deterioration. Remove any blockage and repair the structure to approved
design specifications.
4. Remove accumulated sediment from the pretreatment system and infiltration basin annually or when
depth in the pretreatment unit is reduced to 75% of the original design depth. The system shall be restored
to the original design depth without over -excavation. Over -excavating may cause the required water
table separation to be reduced and may compromise the ability of the system to perform as deigned.
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 pretreatment unit. 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 design depth reads 1.00 feet in the pretreatment unit, the sediment shall be
removed from both the pretreatment unit and the infiltration basin.
5. If the Division determines that the system is failing, the system will immediately be repaired 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.
I acknowledge and agree by my signature below that I am responsible for performance of the five
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.
