About Oregon City Stormwater Division
- Maintains the City’s stormwater system for proper conveyance, flood control, and pollution control
- Maintains, plans, and improves public detention and water quality facilities and streams
- Complies with the management program set forth in the City’s NPDES MS-4 permit
- Meets new environmental requirements set by state and federal agencies
- Implements best management practices while performing operations to protect the surrounding environment
In addition to maintaining the current conveyance system, the Storm Division assists Engineering Services to provide capital improvement upgrades to mitigate conveyance limitations and flooding, increase water resource protection, and add system capacity to accommodate a growing population. The Stormwater Drainage Master Plans and their CIPs identify and prioritize needs and construction projects that are funded by stormutility fees and System Development Charges (SDCs) (collected when building permits are issued). Projects are implemented that protect natural resources and complement the surrounding environment.
The Stormwater Division manages the stormwater collection and treatment systems within the city limits of Oregon City (22 drainage basins, 53 detention ponds). This Division performs the following services to the community:
