The Townsite Data Center appeal filed with the Department of the Interior (DOI) on 27 July now has a second front: the Boulder City Council voted unanimously to lodge its own challenge against the Bureau of Land Management’s (BLM) approval of the project, which would place a data centre on an 80-acre federally-owned parcel in Boulder City, Nevada, and draw upon an already over-stretched Colorado River Basin for its water supply.
How the Townsite Data Center appeal came together
The BLM approval that triggered the legal action flows from Executive Order 14318, issued by the White House in July 2025, which directed the expeditious development of data centres on federally owned lands, largely by bypassing the National Environmental Policy Act (NEPA) and related environmental protections. BLM subsequently approved nearly 90 acres of federal land in Boulder City for the Townsite Data Center project.
The Sierra Club and the Center for Biological Diversity contend that BLM sidestepped environmental review laws by using a prior authorisation for a solar project at the same site to satisfy permitting requirements for the data centre. On 27 July, both organisations filed a formal appeal with the Office of Hearings and Appeals at the DOI. Boulder City then filed its own parallel appeal, and the council’s vote to do so was unanimous.
‘It’s an outrage that the Trump administration is giving away our public lands to hedge funds for data centers. Public lands are for wildlife and clean water, for recreation and spiritual renewal. They’re not meant for big tech companies to spew air pollution and suck down water for AI and the surveillance state,’ said Patrick Donnelly, the Great Basin director at the Center for Biological Diversity.
Olivia Tanager, executive director at the Sierra Club Toiyabe Chapter, framed the stakes beyond a single site: ‘If this isn’t challenged, it won’t stop in Boulder City, it will become the blueprint for data centers across public lands in the West.’
Charter constraints and habitat protections complicate the project’s path
Boulder City’s legal objection is underpinned by local constitutional constraints. According to Ballotpedia, Section 144(1) of the Boulder City Charter limits permitted land uses in the Eldorado Valley Transfer Area, a zone covering more than 100,000 acres south-west of the original Boulder City townsite. The charter provision creates a formal legal basis for the city’s challenge, separate from the environmental arguments advanced by the Sierra Club and the Center for Biological Diversity.
Habitat protections add a further layer of complexity. Over 86,000 acres of the Eldorado Valley Transfer Area is encumbered by a Multi-species Habitat Conservation Easement, placing it beyond the reach of development. The Townsite Data Center site sits within terrain that also functions as habitat for the desert tortoise, a species whose presence would ordinarily trigger additional environmental scrutiny under the very laws that opponents say BLM circumvented.
The appeal documents list the project’s possible harms beyond water consumption: increased electricity demand, a rise in ambient local temperature, noise pollution, and wastewater discharge that could damage the surrounding ecosystem. Crucially, the appellants argue that many of these risks remain unquantified, precisely because BLM approved the project without commissioning additional environmental hazard studies or opening a public comment period.
The Grand Canyon’s water supply is already under pressure
The downstream implications of the Townsite Data Center appeal reach well beyond Nevada. The Colorado River Basin, from which the data centre would draw, is already so stressed that the Department of Reclamation has issued water management initiatives across three states, with usage reductions that could exceed 30%. Grand Canyon National Park relies on the same water source for both daily operations and fire suppression.
Fire suppression is no theoretical concern. On Independence Day 2025, a lightning strike on the North Rim ignited what became the Dragon Bravo fire. It burned for nearly three months, destroying over 70 buildings, including cabins, the North Rim Visitor Centre, and administrative outposts, while consuming nearly 150,000 acres of parkland. Roads and trails began reopening in October, with select campgrounds following in November.
The park was already operating with reduced staff and budget when the fire broke out. Higher temperatures in the American Southwest have accelerated both wildfire risk and visitor fatalities from heat illness, with rock surface temperatures in the Inner Canyon reaching up to 140 degrees Fahrenheit. Less water retention in the parched desert soil compounds the ignition risk each time lightning strikes.
Should the Townsite Data Center appeal fail and the project proceed, the result could be a further reduction in the water available for fire suppression at a park already stripped of its former operational capacity. The DOI’s Office of Hearings and Appeals will now determine whether BLM’s approval process was lawful, with Boulder City’s November 2026 ballot question on data centre land use in the Eldorado Valley Transfer Area providing a parallel democratic test of local sentiment.
