The approval of an incorporation by the voters of a proposed city or town, and the existence of a transition period to become a city or town, shall not remove the responsibility of any county, road district, library district, or fire district, within which the area is located, to continue providing services to the area until the official date of the incorporation.

A county shall continue to provide the following services to a newly incorporated city or town, or that portion of the county within which the newly incorporated city or town is located, at the preincorporation level as follows:

(1) Law enforcement services shall be provided for a period not to exceed sixty days from the official date of the incorporation or until the city or town is receiving or could have begun receiving sales tax distributions under RCW 82.14.030(1), whichever is the shortest time period.

(2) Road maintenance shall be for a period not to exceed sixty days from the official date of the incorporation or until forty percent of the anticipated annual tax distribution from the road district tax levy is made to the newly incorporated city or town pursuant to RCW 35.02.140, whichever is the shorter time period.
