A map shows areas (in green) that would be covered if AT&T located antennae on just the existing tower near the Williamstown-New Ashford town line. WILLIAMSTOWN, Mass. The Zoning Board of Appeals on Thursday sent an applicant who wants to build a cellular tower in South Williamstown back to the drawing board one more time. The board spent two hours discussing an application for a special permit from Pittsfield s Evolution Site Services. In the end, the ZBA opted to continue the public hearing to a fourth meeting in hopes that Christopher Ciolfi can design a tower that is as short as possible and that allows for possible expansion if needed in the future.
