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 nuns of the pump will be kept
on site and made available to DIM 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:
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.
III. 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 3 1.
C. Grassed swales, including the vegetated filter if applicable, will be reseeded twice a year
as necessary.

POND MAINTENANCE REQUIREMENTS
PAGE-i
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 T, whichever is greater. Design
depth is 4 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
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 must be redesigned and/or replaced.
VI. Special Requirements:
I, LIONEL _YOb,L hereby acknowledge that I am the financially
(please print or type name clearly)
responsible party for maintenance of this detention pond. I will be responsible for the performance of the
maintenance as rtlined above, as part of the Stormwater Management Permit received for this project.
