(a) Whether land shall be acquired, retained, devoted, or dedicated to a public purpose shall be determined by ordinance which shall contain the public purpose for which the property is to be dedicated, the legal description of the property, and the address or a general description of the property sufficient to provide the public with notice of its location. This requirement does not apply to rights-of-way or easements dedicated through the City and Borough platting process.

(b) Whether land previously dedicated to a public purpose should be dedicated to a different public purpose or should no longer be needed for public purpose shall be determined by the City Council by ordinance, except in cases of vacation of rights-of-way or easements which may be determined by resolution, either of which shall contain the new public purpose for which the property is to be dedicated or the reason the land is no longer needed for public purpose, the legal description of the property, and the address or a general description of the property sufficient to provide the public with notice of its location.
