Four jurisdictions moved on data-center moratoria in the May 4-8 window. (1) Durham NC city council unanimously approved a 60-day moratorium May 4. The 60-day duration is *not* the council's policy preference — Council member Nate Baker explicitly stated 'I think it is vital that we have no less than a 24-month moratorium on hyper-scale data centers in Durham,' and the council had originally considered a 24-month ban but couldn't proceed because moratoria longer than 60 days require joint city/county planning commission approval (which hadn't yet reviewed the proposed ordinance). The 60-day window is being used to (a) develop more comprehensive ordinance language, (b) coordinate with Durham County's separate moratorium development to avoid misaligned standards, and (c) loop into a possible joint city/county 12-month moratorium structure. (2) Charlotte NC city council debated the moratorium question May 8 — no vote was taken because Mayor Vi Lyles had previously broken a tie vote *against* holding a public hearing on data centers in late April. The May 11 council meeting has a data-center discussion item on the agenda but the council will not vote then; the East Charlotte data-center proposal is on the May 18 council agenda for discussion and public comment, which is the first concrete decision point. Charlotte currently has *no* zoning regulations specific to data centers — they're permitted in several zoning districts without city approval. (3) Seattle Mayor Katie Wilson on May 1 announced detailed plans for a one-year moratorium on data centers ≥10 MW, developed jointly with three city council members. Both the supporting resolution and draft moratorium legislation will be introduced by mid-May (council vote anticipated late May / early June). Background: four developers had approached Seattle City Light proposing five large-scale data centers totaling 369 MW maximum demand combined — equivalent to ~300,000 home loads. Two of those four developers withdrew their plans in late April after public backlash. Seattle City Light is separately finalizing a Very Large Customer rate-structure proposal to ensure infrastructure-and-purchasing costs don't pass through to existing residential ratepayers. (4) Oneida County WI zoning committee advanced a 1-year moratorium ordinance to public hearing on May 8. Oneida is *proactive* — no specific data-center proposal has been filed in the county. Zoning Director Karl Jennrich's framing: 'when we see something coming at other counties, we're supposed to try to address it within our county.' Wisconsin context matters: Madison passed a similar 1-year moratorium in February 2026; the state PSC approved We Energies' Very Large Customer tariff April 24 with 100% participant funding for new generation (large-load customers fund full cost of bespoke generation, 15-year minimum contract, threshold lowered from 500 MW to 100 MW); three NE WI towns called for 1-year moratoria in late April. Tom's Hardware tracker now shows roughly 80+ jurisdictions with active or proposed moratoria — the cluster cadence remains 4-6 actions per week.

Why it matters
Four updates. (1) Durham's 60-day-as-procedural-placeholder is a structurally different pattern from prior moratoria. Most prior moratoria (Northampton 32 months, Apex 12 months, Bulloch 20 months) are substantive duration choices reflecting the council's policy preference. Durham's 60 days is a *procedural artifact* — the council wants 24 months and is using the 60-day window to clear the procedural gate. Cliff's regulatory-risk module should treat any moratorium that has an explicit longer-duration follow-on commitment as 'effectively the longer duration' for hyperscaler underwriting purposes — a 24-month-target moratorium is a 24-month moratorium even if the first vote was 60 days. The 60-day Durham window also creates a coordination-risk vector: if Durham city and Durham county adopt misaligned standards (e.g., city bans hyperscale but county doesn't), developers can rezone-shop the county side of the line. The City Attorney's flag on this is the first time this issue has surfaced explicitly in moratorium-vote language, and Cliff's submission-readiness product should add a 'jurisdiction-coordination-risk' field for sites near city/county boundaries. (2) Charlotte's procedural posture — Mayor breaks tie *against* public hearing, then May 11 discussion-only, then May 18 specific-project public comment — is the slowest-moving moratorium debate in the NC cluster, contrasting sharply with Durham's expedited 60-day vote. The Mayor Vi Lyles tie-break against the public hearing is the structural-veto data point: a moratorium can't easily clear Charlotte's council without the mayor's affirmative support, which means the East Charlotte specific-project decision May 18 becomes the de-facto policy battleground. Watch May 18 closely — if East Charlotte is approved over public objection, it's the first major NC city to *not* impose a moratorium during the May 2026 wave; if denied or paused, Charlotte joins Durham/Apex/Northampton in the broader NC restriction cluster. (3) Seattle's plan is the highest-MW-impact moratorium tracked to date: 369 MW combined demand from 5 proposed sites, 2 already withdrawn, 3 remaining in active siting limbo until council action mid-May to early June. Seattle is also a structurally interesting case because Seattle City Light is municipally owned (not investor-owned utility), which means rate-structure changes don't go through a state PUC — the city council and utility board can move faster than a PSC tariff filing. Mayor Wilson's '2027 legislative session' framing for state-level legislation telegraphs that Washington state-level data-center policy is coming next year; pull WA HB / SB pre-files when they appear in the Dec 2026 / Jan 2027 cycle. (4) Oneida County WI's *proactive* moratorium (no specific proposal pending) is a cadence-shift signal. The previous pattern was reactive — counties pass moratoria in response to a specific filed proposal. Oneida's pattern is preemptive — pass the moratorium framework before a proposal arrives, so the county is never caught flat-footed. If preemptive moratoria become the dominant pattern (as Wisconsin's combined Madison + Oneida + 3-NE-WI-towns + state PSC tariff posture suggests), the moratorium-tracker count of 78/50/4 substantially understates the true policy footprint, because preemptive bans don't appear on developer-watch lists until *after* a developer has wasted weeks on site identification.
