Summary
Any Beaverton property connected to the public storm drainage system must pay a monthly maintenance charge set by council resolution, with a defined path to disconnect if runoff is retained on-site.
A user of property connected to the public storm drainage system shall pay a monthly charge to recover the City's cost of operating, repairing, replacing, and maintaining the system. This charge for the City's public storm water drainage system shall be established by council resolution.
Full Breakdown
Beaverton regulates stormwater drainage through BC Chapter 4.06, not through a standalone environmental permit scheme. Under BC 4.06.010, 'connection' means causing or allowing impervious surfaces or drainage facilities to drain, directly or indirectly, into the public storm and surface water system, including open channels, creeks and rivers. Every connected property owner or occupant pays a monthly charge set by council resolution to cover the City's cost of operating, repairing and maintaining the system (BC 4.06.020). Owners who eliminate impervious surface or install an on-site retention/infiltration system that handles all runoff can apply to disconnect under BC 4.06.040, subject to City Engineer verification.
Violations & Fines
Failing to pay the storm drainage charge is treated like other City utility delinquencies and can lead to collection action; the charge continues until the City Engineer confirms a valid disconnection.
