I. 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 DWQ 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.
II. Quarterly (Four times a year):
A. Inspect the collection system (i.e., 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.
III. Semi-annually (twice a year):
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 original design depth of 3.5 feet
C. Grassed swales, including the vegetated filter if applicable, will be reseeded twice a year as
necessary. Repair eroded areas immediately.

POND MAINTENANCE REQUIREMENTS
PAGE 2
IV. Annually (Once a year):
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 3.5 feet, 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 chemicals 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
accomplished 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.
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 will be redesigned and/or replaced.
V. Special Requirements:

Applicants Initials
a. The temporary pool controls runoff from the 1 inch storm event.
b. The basin length to width ratio is greater than 3:1.
c. The basin side slopes above the permanent pool are no steeper than 3:1.
d. A submerged and vegetated perimeter shelf at less than 6:1 is provided (show detail).
e. Vegetation above the permanent pool elevation is specified.
f. An emergency drain is provided to empty the basin.
g. The permanent pool depth is between 3 and 6 feet (required minimum of 3 feet).
h. The temporary pool draws down is 2 to 5 days.
i. A trash rack is provided for both the overflow and orifice.
j. The forebay volume is approximately equal to 20% of the total basin volume.
k. Sediment storage is provided in the permanent pool.
1. 30-foot vegetative filter is provided at the outlet2 (include erosive flow calculations
in. Recorded drainage easement for each basin including access to nearest right-of-way.
n. A site specific operation and maintenance (O&M) plan is provided.
o. A vegetation management/mowing schedule is provided in the O&M plan.
p. Semi-annual inspections are specified in the O&M plan.
q. A debris check to be performed after every storm event is specified in the O&M plan.
r. Specific clean -out benchmarks are specified in the 0&M plan (elevation or depth).
s. A legally responsible party is designated in the O&M plan3 (include name and title).
t. If the basin is used for sediment and erosion control during construction, clean out of the.
basin is specified to be performed prior to use as a wet detention basin
1When using the Division SA/DA table, 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.
2The requirement for a vegetative filter may be waived if the wet detention basin is designed to meet 90% TSS removal.
3The 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.

substantial compliance with the permit and were observed to be properly maintained.
2. RPS Environmental is currently under contract with the New Hanover County Board of
Education to properly maintain the stormwater SCM's at this facility.
