Section 15-1-506 - Master plan; construction to conform, be approved; overruling disapproval; time limitation(a) If the governing body has adopted the master plan or any part thereof, no street, park or other public way, ground, place or space, public building or structure or public utility, whether publicly or privately owned, may be constructed until its location and extent conform to the plan and have been approved by the commission. If disapproved, the commission shall communicate its reasons to the governing body which by a vote of not less than a majority of its membership may overrule the disapproval. If overruled, the governing body or the appropriate board or officer may proceed. However, if the public way, ground, place, space, building, structure or utility is one which the governing body, or other body or official of the municipality may not authorize or finance, then the submission to the commission shall be by the board or official having that jurisdiction, and the commission's disapproval may be overruled by that board by a majority vote or by that official. The acceptance, widening, removal, extension, relocating, narrowing, vacation, abandonment, change of use, acquisition of land for, or sale or lease of any street or other public way, ground, place, property or structure may be similarly overruled. (b) If the commission fails to act within thirty (30) days after the proposal has been submitted to it, the proposal is deemed approved, unless a longer period is granted by the governing body or other submitting body, board or official.
