Stormwater BMP Operations and Maintenance Plan
1010 E. Hyman Ave
Aspen, CO 81611
Ownership and maintenance of the proposed drainage improvements within private property will
be owned and maintained by the Property Owner and/or Property Owner's Association.
The developed drainage for the site has been designed to minimize maintenance. There are no
mechanical items to check and maintain. Anticipated maintenance includes periodic (1-2 times
per year and as needed after major storm events) clearing of debris from inlets and grates.
Periodic sediment removal from the drywell may also be required. The removal frequency will
vary depending on the sediment removal loading through the system, but it is unlikely sediment
removal would be required more often than once every 5 to 10 years.
Inspection of the drainage facility and associated BMPs shall be conducted annually and after
every storm exceeding 0.5 inches. Sediment, debris/trash, and any other waste material removed
from a dry well shall be disposed of at suitable disposal sites and in compliance with local, state,
and federal waste regulations. The drain-time of the dry well shall be routinely evaluated to ensure
the maximum time of 24 hours is not being exceeded. If drain-down times are exceeding the
maximum, drain the dry well via pumping and clean out the percolation area (the percolation barrel
may be jetted to remove sediment accumulated in perforations). Consider drilling additional
perforations in the barrel (on the eastern side). If slow drainage persists, the system may need to
be replaced.
A signed Operation and Maintenance Agreement accompanies this plan.
1. Provide a basic site plan showing a
location of all inlets, clean-outs and drywell.
2. Provide a maintenance log/schedule
3. Provide a 8.5" x 11" copy of the as-built
for recordation purposes.
