Maintenance: activities shall be performed as follows:
l . After every significant runoff producing rainfall event and at least monthly:
a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation,
vegetated cover, and general condition.
b. Check and clear the orifice of any obstruetions;such thatArawdown of the temporary pool occurs
within 2 to 5 days as designed.
2. Repair eroded areas iiumcdiately, re -seed as necessary to maintain good vegetative cover, mow vegetative
cover to maintain a maximum height of six -inches, and remove trash as needed.
3. inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to
maintain proper functioning.
4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is
reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed
of,in ah appropriate.manner and shall be handled in a manner that will not adversely impact water quality
(i.e. stockpiling near a wet detention basin or stream, etc.). '
The measuring device used to determine the.sediment elevation shall be such that it will give an accurate
depth reading and not readily penetrate into accumulated sediments:
When the pennanent pool depth reads 5.62 feet in the main pond, the sediment shall be removed.
When the pennane:nt pool depth reads 1.75 feet in the forebay, the sediment shall be removed.

through the emergency drain shall be minimized to the maximum extent practical.

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 (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. Ripr-ap 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 the originaI forebay design depth of 3 it .
C. Grassed swales, including the vegetated filter if applicable, will be reseeded twice a year as
necessary.

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 T, whichever is greater. Design
depth is 6 ft. ', 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 must be redesigned and/or replaced.
VI. Special Requirements:
I, Id Rill , 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 outlined above, as part of the tormwater Management Permit received for this project.
