Section 15-1-508 - Major street plan; official map; contents; procedure; effect; recording ordinance(a) After the commission has adopted a major street plan, the governing body may establish an official map of the whole or any part of the existing public streets. The map may also show the location of the lines of streets on plats of subdivisions which the commission has approved. The governing body may make other additions to or modifications of the official map by extending the lines of proposed new streets or street extensions, widenings, narrowings or vacations which have been accurately surveyed and definitely located. Before taking any such action the governing body shall hold a public hearing thereon. Any proposed addition to or modification of the official map shall be submitted to the commission for its approval. If the commission disapproves, approval of the addition or modification then requires an affirmative vote of not less than a majority of the governing body. (b) The placing of any street or street lines upon the official map does not of itself constitute the opening or establishment of any street or the taking or acceptance of any land for street purposes. (c) The governing body shall direct that the adopted ordinance creating the official map be recorded in the office of the county clerk.
