This Zoning Chapter of the Town of Southborough, Massachusetts, has been adopted and from time to time amended and recodified under the authority of Chapter 40A and other relevant provisions of the General Laws of Massachusetts for the purpose of protecting and promoting the health, safety, convenience and welfare of the current and future inhabitants of Southborough and for other purposes contained in Section 2A of Chapter 808, Acts of 1975.
