The Planning Commission is hereby granted the authority to require, and shall require prior to its public hearing, as a condition to consideration of any proposal for amending, supplementing, changing, modifying, or repealing the zoning regulations, restrictions or boundaries, that a proposal originating from the Council, or from the Planning Commission itself, or from a petition of a property owner, be prepared and submitted accompanied by such maps, charts, sketches, rationale and other information as the Planning Commission reasonably deems necessary for the proper and effective consideration of such proposal (zoning support information), and the Planning Commission shall refuse to consider any proposal not complying with such requirement. Citizens shall be permitted to examine, review, and receive copies of all zoning support information in accordance with the Delaware Freedom Of Information Act. The Planning Commission shall provide the Council with its recommendation for action of the amendment request upon completion of its review and conduct of a duly advertised public hearing, but no later than the greater of:
(1) Ninety days following its initial receipt of the proposal or petition; or
(2) Sixty days of its receipt of a complete set of zoning support information as requested by the Planning Commission.
