Where any real property is acquired by the Village of Kensington for a public use, whether by dedication, purchase, condemnation or otherwise, and as a result of such acquisition other real property not so acquired fails to conform to the regulations of this chapter or Building Code in force at the time of such acquisition, the Board of Trustees may, by general resolution authorizing the improvement or by special resolution authorizing the acquisition of a specific parcel of real property, adopt other regulations applying to such real property which fails to conform as aforesaid, which shall take the place of the regulations with which it fails to conform; provided, however, that such resolution or regulation shall be adopted in the same manner as an ordinance amending this chapter or Building Code generally.
