(a) The city council may sell and convey, or lease any real or personal property owned or held by the city for governmental or other purposes as now or hereafter provided by law.

(b) The city council may quitclaim any rights it may have in property not needed for public purposes upon report by the mayor and adoption of a resolution, both finding that the property is not needed for public or other purposes and that the interest of the city has no readily ascertainable monetary value.

(c) Whenever in opening, extending or widening any street, avenue, alley, or public place of the city, a small parcel or tract of land is cut off or separated by such work from a larger tract or boundary of land owned by the city, the city council may authorize the mayor to sell and convey said cut-off or separated parcel or tract of land to an abutting or adjoining property owner or owners where such sale and conveyance facilitates the enjoyment of the highest and best use of the abutting owner's property. Included in the sales contract shall be a provision for the rights of way of said street, avenue, alley or public place. Each abutting property owner shall be notified of the availability of the property and given the opportunity to purchase said property under such terms and conditions as set out by ordinance. All deeds and conveyances heretofore and hereafter so executed and delivered shall convey all title and interest the city has in such property, notwithstanding the fact that no public sale after advertisement was or is hereafter made.
