New Drainage Rate Structure
The City of Seattle charges property owners a fee for stormwater management services based on each property’s estimated impact on the City’s drainage system. These fees are billed as a separate line item on King County property tax statements.


Starting Jan. 1, 2008, the City of Seattle will change the drainage rate structure which underlies the calculation of the drainage fee. The new structure improves equity among customers by more accurately reflecting customers’ impacts on the drainage system. Read our drainage rate structure frequently asked questions to learn more.
