The public hearing held pursuant to Section 40725 shall provide for the submission of statements, arguments, or contentions, either oral, written, or both. A district board may continue or postpone the hearing from time to time, to a time and place as it shall determine. Following consideration of all relevant matter presented, a district board may adopt, amend, or repeal a rule or regulation, unless the board makes changes in the text originally made available to the public that are so substantial as to significantly affect the meaning of the proposed rule or regulation. The board shall not take action on a changed text before its next regular meeting, and shall allow further statements, arguments, and contentions, either written, oral, or both, to be made and considered prior to taking final action.
