(2) The procedures in the exercise of the powers of eminent domain and the assessment of damages and benefits for property taken, injured or destroyed.
(3) Boundary changes.

No home rule municipality shall establish or levy a rate of taxation upon nonresidents which is greater than the rate which a municipality would have been authorized to levy on nonresidents but for the adoption of a home rule charter. The governing body shall not be subject to any limitation on the rates of taxation imposed upon residents.

(4) Enact or promulgate any ordinance or regulation with respect to definitions, sanitation, safety, health, standards of identity or labeling pertaining to the manufacture, processing, storage, distribution and sale of any foods, goods or services subject to any Commonwealth statutes and regulations unless the municipal ordinance or regulation is uniform in all respects with the Commonwealth statutes and regulations thereunder. This paragraph does not affect the power of any municipality to enact and enforce ordinances relating to building codes or any other safety, sanitation or health regulation pertaining thereto.
(5) Enact any provision inconsistent with any statute heretofore enacted prior to April 13, 1972, affecting the rights, benefits or working conditions of any employee of a political subdivision of this Commonwealth.
