(1) The director shall assign all developed real property located in areas annexed by cities and towns to service charge rate categories according to the land use classification and the degree of impervious surface coverage of the real property. The "Index of Land Use Classifications and Rate Categories" dated January 8, 2002, or any revision thereafter compiled by the director, is available in the department of conservation and resources and incorporated by this reference. When assigning real property to appropriate service charge rate categories, if portions of any tax parcel or legal lot have been placed into separate taxation categories by the county assessor, the director shall treat each of those separate portions of the tax parcel or legal lot as separate properties and assign an appropriate service charge rate category to each. When assigning the real property to appropriate service charge rate categories, if the property exhibits mixed use, the director shall assign the rate category based on the use associated with the majority of the impervious surface area on the real property.

(3) A reasonable administrative fee in an amount sufficient to reimburse the county for its actual, reasonable costs of performing administrative functions related to the service charges shall be added to the amount charged.

(4) Rights-of-way owned by the state shall be subject to annual service charges to the extent permitted by law.

(5) Service charges collected under this section shall be used solely for purposes permitted by RCW 36.89.120.
