Upon the hearing of any protest, the governing body may grant or deny the same except that it shall not deny the written protests of the owners of a majority of the area of property lying within any proposed street to be opened or of a majority of the owners of the frontage of a street to be widened and upon which a future street line is established except by a four-fifths vote of such governing body. The governing body may grant or sustain protests as to the entire proposed future street line or lines or only as to a portion thereof. The governing body may deny the protest or protests as to any portion of such proposed future street line or lines concerning which a protest is not granted or sustained. Upon the denial of any such protest, the resolution shall become effective immediately. If no protests are filed, such resolution shall take final effect at midnight of the last day for filing protests.
