Subject to the provisions of the joint consolidation agreement or elector initiated consolidation plan, as the case may be, pertaining to the common administration and uniform enforcement of laws in the consolidated local government entity, all local laws, ordinances, rules or regulations of the component local government entities in effect on the effective date of consolidation shall remain in full force and effect within the respective areas of the component local government entities that existed prior to consolidation, insofar as the local laws, ordinances, rules or regulations are not repugnant to law, until repealed or amended. As soon as practicable but not later than two years after the effective date of consolidation, the governing body of the consolidated local government entity shall adopt new local laws, ordinances, rules and regulations as necessary to redress conflicts and otherwise redress ambiguities arising among the then-existing laws, ordinances, rules or regulations for the common administration and uniform governance of the consolidated local government entity.
