13.70.030 Service charge rate.
A. Subject to the rate adjustments provided in LMC 13.70.035, the storm and surface water utility charges shall be levied upon the basis of a flat monthly rate for all developed single-family residential parcels and two-family residential parcels and a sliding rate for all other parcels. The sliding rate shall be determined by measuring the amount of impervious surface area on each parcel and dividing that figure by the total area of the parcel to determine the percent of impervious surface and therefore the rate category. The monthly charge shall be that amount resulting from multiplying the service charge for the rate category applicable to the parcel by the total area of the parcel. The rate categories, the parameters of impervious surface for said rate categories and the monthly service charge applicable to each category shall be as follows:
