10.30.100 Property Classification for Stormwater User’s Fee.
As authorized by RCW Chapters 35.67 and 35.92, the City Council finds that variations in land use and impervious surface results in differences in the burdens imposed upon the stormwater system and the costs to serve such parcels. City parcels shall be differentiated from one another based upon the stormwater burdens imposed and the costs of City stormwater services.
(1) Customer Classification. For purposes of determining the stormwater user’s fees, owners of all developed parcels in the City are classified into one of the following general classes:
(a) Residential;
(b) Duplex, Tri-plex and Four-plex; and
(c) Non-residential.
To reflect the burdens imposed upon the City stormwater system, parcels with facilities deemed to be more industrial or commercial in nature will have fees determined in the same manner as the non-residential class regardless of the land use codes assigned by the City.
(2) Residential Fee. The stormwater fee for residential parcels shall equal the base rate. The fee for commercial mobile/manufactured home parks and condominiums shall be determined using the same methodology as used for non-residential parcels.
(3) Duplex, Tri-plex, and Four-plex Fee. The stormwater fee for a duplex, tri-plex and four-plex shall equal one half the base rate multiplied by the number of dwelling units.
(4) Non-Residential Fee. Owners of developed non-residential parcels shall pay a stormwater fee equal to the base rate multiplied by the numerical factor obtained by dividing the estimated total impervious surface area of the parcel by one ERU. The minimum stormwater fee for developed non-residential parcels shall equal the base rate for residential parcels. (Ord. 09-2 §11, 2009).
