Greenfield's City Council voted UNANIMOUSLY on a roll call on Wednesday, September 16, 2026 to adopt a ONE-YEAR moratorium on data centers, while the Planning Board works on zoning codes and regulations. The interesting part is what the councilors argued about before voting. They agreed the moratorium was a good idea but pressed on the logistics: what happens if, in a year, the Planning Board has NOT finished drafting language — or brings forward language the council does not accept? THE MORATORIUM ANSWERS THE FIRST HALF OF THAT QUESTION IN ITS OWN TEXT. It includes language providing that IF THE PLANNING BOARD IS UNABLE TO PUT FORTH RECOMMENDATIONS IN THAT TIME FRAME, THE CITY COUNCIL CAN EXTEND THE MORATORIUM BY 180 DAYS. Very few measures in this dataset build the extension into the original instrument; most require a fresh enactment, which is precisely the moment a pause tends to lapse by inattention. Precinct 1 Councilor Katherine Golub asked whether the council could simply vote against extending and adopt its own language instead, and City Clerk Kathy Scott said that if the council votes down any proposal, it m[ust follow a further process]. The council concluded that rather than work through hypotheticals about next year, it should focus on the proposal in front of it. Context matters here: earlier this month Governor Maura Healey signed an executive order banning data centers that are not approved locally. Greenfield is exercising exactly the local authority that order preserves — and a municipality that has paused its own approvals has, in effect, withheld the local consent the state order now requires.

Legal detail

Greenfield, Mass. (Franklin County) — ONE-YEAR MORATORIUM ON DATA CENTERS adopted UNANIMOUSLY ON ROLL CALL by the City Council on WEDNESDAY, SEPTEMBER 16, 2026. PURPOSE: to give the PLANNING BOARD time to work on zoning codes and regulations related to data centers. THE DISTINGUISHING FEATURE IS A SELF-CONTAINED EXTENSION CLAUSE: the moratorium 'includes language that states IF THE PLANNING BOARD IS UNABLE TO PUT FORTH RECOMMENDATIONS IN THAT TIME FRAME, CITY COUNCIL CAN EXTEND THE MORATORIUM BY 180 DAYS.' MOST INDEXED MORATORIA REQUIRE A FRESH ENACTMENT TO EXTEND, which is the failure point where pauses lapse through inattention rather than decision. Building the extension into the original instrument converts extension from a new legislative act into an exercise of a reserved power. Compare Loveland CO 12-month data center moratorium (2026), which solves the adjacent problem from the other direction — a self-TERMINATING ceiling that ends the pause early if replacement regulations are adopted sooner. Greenfield guards against the drafting running long; Loveland guards against it running short. Read together they are the two halves of a well-drafted moratorium term. THE COUNCIL DEBATE IS RECORDED BECAUSE IT IDENTIFIES THE UNSOLVED HALF: councilors questioned not only what happens if the Planning Board fails to finish, but what happens if it 'brings forth language that' the council does not want. PRECINCT 1 COUNCILOR KATHERINE GOLUB asked whether the council could simply vote against extending the moratorium and adopt its own language; CITY CLERK KATHY SCOTT replied that if the council votes down any proposal, it m[ust — the sentence is truncated in the retrieved text]. THE ANSWER IS THEREFORE NOT CAPTURED, and this entry does not supply one. Under the Massachusetts Zoning Act (G.L. c. 40A, § 5) a zoning amendment ordinarily requires a planning board hearing and report before the legislative body may adopt it, with a time limit after which the body may act without the report — which is the likely subject of the clerk's answer, but THAT IS INFERENCE AND IS NOT ASSERTED. The council resolved to focus on the proposal before it rather than hypotheticals. STATE CONTEXT, AND IT IS SUBSTANTIAL: Massachusetts EO 658 responsible data center development (2026) records Gov. MAURA HEALEY's Executive Order No. 658 of 2026-09-08, 'Establishing Requirements for Responsible Data Center Development and Operations in Massachusetts,' accompanied by a release titled 'Governor Healey: No Data Centers Without Local Approval.' GREENFIELD ADOPTED ITS MORATORIUM EIGHT DAYS LATER. THE INTERACTION IS WORTH STATING PRECISELY: the executive order conditions data center development on local approval; a municipality that has suspended its own approval process has, for the duration, withheld the consent the state instrument requires. The moratorium and the order are therefore mutually reinforcing rather than redundant — the order makes the local pause dispositive statewide rather than merely local. expires_date IS COMPUTED as one year from adoption and is NOT stated in the source; note that the built-in extension makes 2027-09-16 a presumptive rather than final endpoint. NO ORDINANCE NUMBER, NO VOTE COUNT BEYOND 'UNANIMOUSLY', AND NO OPERATIVE SCOPE (whether applications, permits or construction are barred) WERE OBTAINED.
