Commercial and Multifamily Drainage Facility Maintenance Checklist (125KB)

Directions for property owner/manager or maintenance vendor:

1. Refer to the component definitions in the "Drainage Maintenance Standards" booklet, as well as your individual site plan to determine what facilities you have on your property. On a site plan, "CB" refers to catch basin.
2. Check "yes" or "no" indicating whether you have each facility component on your property (i.e., pond, Type II catch basin, culvert, etc.).
3. Inspect each component to determine whether it has any defects causing it to not meet the King County standard (see "Drainage Maintenance Standards" booklet).
4. In the "Meets Standard or Defect Number" column, list the applicable defect number (A-1, A-2, etc.) from the Drainage Maintenance Standards booklet, or write "Meets Standard" if the facility meets the standard. (NOTE: If there is more than one component for a facility type, list each component by its number on the site plan (CB-1, CB-2, etc.) along with any defect numbers.
5. Perform maintenance on all defective facility components to bring them up to standard.
6. Check off the work that has been completed and the date it was completed.
