Eugene, OR Environmental Rules: Stormwater Management (2026)

EC 6.600 (current through Ordinance 20739, passed June 8, 2026) creates an obligation to pay stormwater service charges whenever a property uses stormwater services, presumed whenever the premises is improved; the person paying water utility charges pays the stormwater charge unless another responsible person has agreed in writing. EC 6.615 then governs the facilities themselves: unless the city has agreed to accept maintenance, every stormwater management facility built under the design standards at EC 9.6790 to 9.6797 must be privately operated and maintained according to an Operations and Maintenance Plan filed with the city, with periodic compliance reports due on a schedule set by administrative rule.

The city may inspect facilities at reasonable times, and property owners cannot refuse entry without the city seeking a warrant or other legal remedy. Failing to properly operate or maintain a facility, or to file the required reports, can trigger a stop work order, a compliance order, a municipal court citation, an administrative civil penalty under EC 2.018, and abatement as a nuisance under EC 6.005 to 6.115, including full restoration of any damage to open waterways. In a homeowners' association or condominium development, every unit can be held liable for an unpaid administrative civil penalty tied to a shared stormwater facility, and the city may lien each unit for its share.
