Section 29.40.160 - Title to vacated area(a) The title to the street or other public area vacated on a plat attaches to the lot or land bordering the area in equal proportions, except that if the area was originally dedicated by different persons, original boundary lines shall be adhered to so that the street area that lies on one side of the boundary line shall attach to the abutting property on that side, and the street area that lies on the other side of the boundary line shall attach to the property on that side. The portion of a vacated street that lies inside the limits of a platted addition attaches to the lots of the platted addition bordering on the area. If a public square is vacated, the title to it vests in a city if it lies inside the city, and in the borough if it lies inside the borough but outside all cities. If the property vacated is a lot, title vests in the rightful owner.(b) If the municipality acquired the street or other public area vacated for legal consideration or by express dedication to the municipality other than as a subdivision platting requirement, before the final act of vacation the fair market value of the street or public area shall be deposited with the platting authority to be paid to the municipality on final vacation.(c) The provisions of (a) and (b) of this section apply to home rule and general law municipalities.(d) The council of a second class city located outside a borough may vacate streets, alleys, crossings, sidewalks, or other public ways that may have been previously dedicated or established when the council finds that the streets, alleys, crossings, sidewalks, or other public ways are no longer necessary for the public welfare, or when the public welfare will be enhanced by the vacation. If the council determines that all or a portion of the area vacated under this subsection should be devoted to another public purpose, title to the area vacated and held for another public purpose does not vest as provided in (a) of this section but remains in the city.
