The council adopted the zoning amendment on second passage as amended: it removed the 2-megawatt aggregate power demand threshold from the definition and added language that data centers do not include servers and IT infrastructure that are accessory, incidental and subordinate to a lawful principal use, while excluding third-party data storage or hosting businesses. Discussion described the measure as effectively temporary while a broader data-center policy and working group are developed. The vote carried by voice vote.

The committee struck the 2 megawatt aggregate power threshold proposed by the Planning Board, added accessory-use language excluding ordinary server rooms and IT infrastructure but covering third-party storage, hosting and distributed processing, and voted 5-0 to send the amended ordinance to the full council with a positive recommendation. A resident asked for a moratorium instead.
