Permit No. SW8 960329
This stormwater system has been approved for the management of stormwater runoff as
described in Sections 1.10 and 1.11 of this permit. The stormwater controls and drainage
areas have been identified as follows and have been designed to handle the following
amounts of build -upon area (BUA):

3. The drainage area for Pond J includes 35,304 square feet of drainage area and the
associated impervious area from a part of the low density project area previously
permitted under the Base Entry Point and Road permit (SW8 090630) that could not be
routed around the collection system. The permit for SW8 090630 appears to have been
modified on May 29, 2012 to include the additional built -upon area. Since this area is
covered under both this permit, SW8 960329, and SW8 090630 any future
improvements within the affected area will impact both permits.
The drainage area labeled "2017 Redevelopment' is exempted from State Stormwater
permitting requirements under the following conditions:
a. The project must be constructed as shown on the plans submitted to this Office,
b. The total proposed built -upon area of 52,718 square feet does not exceed the
existing built -upon area of 52,718 square feet; and,
C. The proposed stormwater control, sheet flow over vegetated areas, provides
equal protection of surface waters as the existing stormwater control, which is
sheet flow over vegetated areas.
5. The additional infiltration areas shown on the plans have not been demonstrated to meet
State Stormwater BMP design requirements and therefore is not considered a part of the
approved state stormwater treatment system. These additional measures are
incorporated only by reference and are not enforceable parts of the permit.
6. A 50 foot wide vegetative buffer must be provided adjacent impounded structures,
streams, rivers and tidal waters.
7. The wet detention ponds and infiltration basin do not require a vegetated filter strip.
8. The tract and drainage areas will be limited to the amount of impervious area indicated
on the application and in Sections 1,2, 1.10, and 1.11 of this permit, and per approved
plans. The built -upon area for future development within the drainage areas labeled J
and "2017 Redevelopment' is limited to 10,000 and 5,730 square feet, respectively.
Within the other drainage areas, there is no impervious area allocated for the future
development.
9. The runoff from all impervious areas within the permitted drainage areas of this project
must be directed into the permitted stormwater control system within drainage areas
labeled East (or G), West (or H), A, B, C, D, E. F, and J.

Wet Detention Basin Operation 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 ® 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 minimized 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 operation and maintenance should be kept in a known set
location and must be available upon request.

Monthly, or after every runoff producing rainfall event, whichever comes first:
A. Inspect the trash rack; remove accumulated debris, repair/replace if it is, not functioning.
B. Inspect and clear the orifice of any obstructions. If a pump is used as the drawdown
mechanism, pump operation will be checked. A log of test runs of the pump will be kept
on site and made available to DEM personnel upon request.
C. Inspect the pond side slopes and grassed inlet swales; remove trash, and repair eroded
areas before the next rainfall event.
D. If the pond is operated with a vegetated filter, the filter will be checked for sediment
accumulation, trash accumulation, erosion and proper operation of the flow spreader
mechanism. Repairs/cleaning will be done as necessary.
Quarterly:
A. Inspect the collection system (ie. catch basins, piping, grassed swales) for proper
functioning. Accumulated trash will be cleared from basin grates, basin bottoms, and
piping will be checked for obstructions and cleared as required.
B. Pond inlet pipes will be checked for undercutting. Riprap or other energy dissipation
structures will be replaced, and broken pipes will be repaired.
Semi-annually:
A. Accumulated sediment from the bottom of the outlet structure will be removed.
B. The forebay depth will be checked at various points. Sediment removal is required when
the depth is reduced to 75 % of the original forebay design depth of one '

IV. Annually:
A. The pond depth will be checked at various points. Sediment removal is required when the
depth is reduced to 75% of the original design depth or 3', whichever is greater. Design
depth is ', measured vertically from the orifice down to the pond's bottom.
Sediment must be removed to at least the original design depth.
V. General:
A. Mowing of the side slopes will be accomplished according to the season. Maximum grass
height will be 6".
B. Cattails are encouraged along the pond perimeter, however they will be removed when they
cover more than 1/2 the surface area of the pond. The best time to cut them is at the end
of the growing season, in November. Environmentally sensitive chemical for use in killing
cattails can also be used. Contact your nearest Agricultural Extension Agent.
C. The orifice/pump is designed to draw down the pond in 2-5 days. If drawdown is not
accomphshed in that time, the orifice will be replaced with a larger or smaller orifice.
Slow drawdown may be attributed to a clogged system. The source' of the clogging will
be found and eliminated.
i
D. All components of the detention pond system will be kept in good working order. Repair
or replacement components will meet the original design specifications as per the approved
stormwater plan. If previously approved components are determined to be ineffective, the
component must be redesigned and/or replaced.
VI. Special Requirements:

Wet Detention Basin Operation 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 ® 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 minimized 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 operation 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.
