The governing body may by ordinance adopt or amend an official map of the municipality, which shall reflect the appropriate provisions of any municipal master plan; provided that the governing body may adopt an official map or an amendment or revision thereto which, in whole or in part, is inconsistent with the appropriate designations in the subplan elements of the master plan, but only by the affirmative vote of a majority of its full authorized membership with the reasons for so acting recorded in the minutes when adopting the official map. Prior to the hearing on the adoption of any official map or any amendment thereto, the governing body shall refer the proposed official map or amendment to the planning board pursuant to subsection 17a. of this act.
The official map shall be deemed conclusive with respect to the location and width of streets and public drainage ways and the location and extent of flood control basins and public areas, whether or not such streets, ways, basins or areas are improved or unimproved or are in actual physical existence. Upon receiving an application for development, the municipality may reserve for future public use, the aforesaid streets, ways, basins, and areas in the manner provided in section 32.
