Catch Basins

Catch basins are used to pre-treat storm and surface water in parking lots prior to discharging to our streams. Cleaning your catch basin can help reduce localized flooding and helps protect our local waterways.  

All catch basins in parking lots are the responsibility of the private property owner to maintain and clean. Early summer is the perfect time for removing sediment from catch basins before the heat bakes the sediment into place. Early fall is a perfect time for removing leaves from catch basins, before the heavy rains and leaf fall. 

Failure to keep catch basins clean is a violation of Lake Oswego Municipal Code 38.24.520 and subject to fines.
