The Township Council may, on its own motion, on a recommendation of the Planning Board or on petition or other application, after public notice and hearing, amend, supplement or change this chapter.

All proposed changes of this chapter shall be referred by the Township Council to the Planning Board for its recommendations. Failure of the Planning Board to make its recommendations on any proposed change within 35 days shall have the same effect as approval thereof.

In the event of an unfavorable report to the Township Council by the Planning Board or of a protest petition filed with the Municipal Clerk and signed by owners of 20% or more either of the area of the lots or land included in the change or of the lots or land extending 200 feet in all directions therefrom, inclusive of street space, such amendment shall not become effective except by the favorable vote of 2/3 of all members of the Township Council.
