The zoning regulations imposed and the districts created under authority of this act may be amended, supplemented, changed, modified or repealed from time to time by resolution of the board as it affects its jurisdiction, but no such change shall be made without public notice and hearing and the filing of a report and recommendations upon such proposed change by the commission. In case of written protest against any proposed change, signed by the owners of twenty percent (20%) or more of the area of land in such proposed change, or by the owners of twenty percent (20%) or more of the frontage within one thousand feet (1000') to the right or left of the frontage proposed to be changed, or by the owners of twenty percent (20%) or more of the frontage directly opposite the frontage proposed to be changed, or in cases where the land affected lies within one and one-half (1 1/2) miles of the limits of a municipality having a zoning ordinance, by the governing body of such municipality filed with the commission, such amendment or change may not be made except by the unanimous favorable vote of all members of the board.

All projects or matters that fall within the purview of the duties of the commission, as specified in this section shall be referred to the commission for investigation and report before any final action shall be taken thereon; provided, however, that if said commission fails to make an investigation and report on any matter or subject referred to it for a period of thirty (30) days, such failure shall be considered a refusal to approve the proposed plan or project and the board shall be under no obligation to wait longer for reports or recommendations concerning said projects.
