Data center scrutiny — Monarch PUD, moratorium, and earthquake preparedness
Summary
Nevada isn't in the ShakeAlert early-warning network yet, but Congress directed the USGS to develop a plan to add the state. The seismological lab wants local help building use cases — what could we do with 30–45 seconds of warning — to convince the feds to fund it here.

Impact analysis
Getting Nevada into ShakeAlert would require federal appropriations; no local cost was discussed.
Everyone in the county — especially schools, hospitals, utilities, and chemical facilities — would gain seconds of life-saving warning before strong shaking.
Data center and renewable energy developers could face new study requirements and delays.

Dayton Regional Advisory Board - Oct 14, 2026
Several data center projects in the Dayton area are moving forward, and the second phase of the Greenlink project has been approved. These developments could bring jobs and infrastructure investment to the region.
Smith Valley Advisory Council - Sep 2, 2026
The county commissioners approved a zoning change for the Monarch Data Center, and residents are worried about constant noise, water use, and whether the location fits. County staff is drafting data center regulations, but no moratorium is planned.
Wildlife Advisory Board - Aug 12, 2026
Board member Mike Osterman warned that Lyon County's newly approved data center — and its huge water use, noise, and new power lines — could harm wildlife springs and guzzlers. He wants the state commission to demand scientific studies before data centers, solar farms, or wind farms get a green light.
Planning Commission - Aug 11, 2026
Staff confirmed the Monarch Data Center tentative PUD got final approval August 6, and Microsoft has grading permits in hand with two to three years of grading ahead. The TRACT natural gas trucking station and a Winston Solar setback amendment are also moving through the pipeline.
Board of County Commissioners - Aug 6, 2026
A recurring theme from the public: Lyon County's data center ordinance isn't adopted yet, and this project is grandfathered out of it anyway. Dozens of speakers demanded a moratorium like Humboldt County and Reno adopted; the board continued its ordinance workshop process but did not act on a moratorium.

Smith Valley Advisory Council - Aug 5, 2026
County officials reviewed draft data center rules covering setbacks, noise, lighting, water-consuming cooling bans and decommissioning requirements. The BOCC adopted revisions unanimously, and Copia Power's zone change for the Monarch Data Center goes before commissioners.
Board of County Commissioners (Special) - Aug 3, 2026
The proposed Monarch data center near Yerington — roughly 505 acres rezoned from rural residential to PUD — dominated public comment. Speakers demanded denial, continuance, or its removal from Thursday's August 6 agenda; tribal members voiced formal opposition.
Board of County Commissioners - Jul 16, 2026
Residents demanded a moratorium on the data center, a hearing on the approved Monarch PUD before it advances, and earthquake preparedness planning. Commissioners face agenda requests on all three.
Lyon County Local Emergency Planning Committee - Jul 15, 2026
Nevada isn't in the ShakeAlert early-warning network yet, but Congress directed the USGS to develop a plan to add the state. The seismological lab wants local help building use cases — what could we do with 30–45 seconds of warning — to convince the feds to fund it here.
Planning Commission - Jul 14, 2026
The county is drafting a data center ordinance; a workshop is set for August 3, 2026, at 9 a.m. in the board chambers. This project's application predates the ordinance, so it will be reviewed under current code.
Board of County Commissioners - Jul 2, 2026
Multiple residents asked the county to formally pause new data center approvals, citing power grid strain, water use, noise and the pace of development. The board took no action but is planning a dedicated workshop and warns of misinformation online.
Board of County Commissioners - Jun 18, 2026
Data centers dominated public comment all morning. The board scheduled a workshop on the draft Data Center Ordinance for August 3, 2026, but residents demanded an evening meeting, a bigger venue, longer comment periods, and access to the draft beforehand.
Planning Commission - Jun 10, 2026
Commissioners and residents keep asking what data centers actually are, how much water and power they use, and whether Lyon County has standards for them. Staff is drafting a data center ordinance and plans a public workshop, possibly in August.
Board of County Commissioners - May 21, 2026
A resident charged during public comment that Lyon County is not being a responsible steward with mega-solar farms, citing low panels harmful to wildlife, water being piped out of the county for projects in Mineral County, and the loss of agricultural water rights.
Planning Commission - May 12, 2026
A data center ordinance is in the works with performance-based standards, and Commissioner Jones pressed whether the county should compensate property owners whose land becomes undevelopable when big projects like Microsoft's data center campus locate nearby. This is an emerging fight over who bears the cost of growth.
Board of County Commissioners - May 7, 2026
Two residents pressed the board on data centers — one worried they'll strain the Carson River watershed, another asked point-blank what's left before they're approved. County Manager Haskin noted Dayton's water has tested clean for PFAS, and the county is finishing a data center ordinance with a workshop coming.
Board of County Commissioners - Apr 16, 2026
Emergency Management credited a strong countywide response to the recent earthquake near Silver Springs, and the Board discussed notifying manufactured-home owners about checking foundation supports.
Board of County Commissioners - Mar 19, 2026
Three hyperscale data center campuses (plus a gas plant) are proposed on BLM land near Silver Springs, promising ~300 jobs and ~$30 million a year in taxes per campus. But the Chair and Vice Chair opposed them, citing the finite water supply, residential zoning, and the pattern of cheap public land with abatements.
Board of County Commissioners - Jan 15, 2026
Chair Keller wants the county to study creating a dedicated data center land-use classification, modeled on Loudoun County, Virginia's 300-plus data centers. This could shape how future data center projects are permitted in Lyon County.

Monarch Data Center
Residents worry about constant noise and water use, though the county says the project will use 60% less water than current ag operations and follow strict noise rules.
Monarch Data Center zone change
The zone change would clear the way for a data center in the valley, an issue locals are watching closely.
Monarch Data Center / Copia Power PUD rezone (PLC 2026-041)
If approved as proposed, it would be one of the largest data centers in the country, drawing an estimated up to 800 acre-feet of water and raising noise, traffic and health concerns for a currently rural-residential area.
Monarch Data Center Planned Unit Development
If the Board approves, Yerington gains a massive industrial energy-and-computing campus promising thousands of construction jobs and over a billion dollars in property tax revenue — alongside years of construction traffic, potential noise, and ongoing water use from existing agricultural rights.
