Littleton City Council will take up a proposed six-month moratorium on new data center development Tuesday, a measure aimed at buying city staff time to study how the booming industry's water, energy and noise demands might clash with nearby homes. The pause would halt new projects while officials draft standards that currently don't exist anywhere in the city's land-use code.
As reported by the Denver Gazette, Littleton's unified land use code does not currently define data centers as a distinct land use and includes no standards specifically designed to address their impacts, even though the facilities are already allowed as a conditional use in mixed-use districts and permitted outright in business and industrial zones. City officials argue additional study is needed before more facilities are approved, and the proposed ordinance would direct staff to examine land-use, energy, water, noise, air-quality, infrastructure and economic effects before the city moves forward with any new rules.
The measure is scheduled for a first reading Tuesday, with a public hearing, comment period and second reading set for November 3, per the Gazette's reporting. City officials have said the facilities' characteristics may be incompatible with nearby residential neighborhoods and some of the city's comprehensive-plan goals — even as supporters of the industry counter that data centers bring jobs, investment, tax revenue and, backers argue, benefits to national security.
A Statewide Scramble After Lawmakers Punted
Littleton isn't moving in isolation. Colorado municipalities have adopted similar moratoriums across the Front Range and beyond, largely because the state legislature left a regulatory vacuum behind. The Colorado General Assembly killed both major statewide data center bills in May 2026 — HB26-1030, which offered tax incentives for large investments, and SB26-102, which proposed environmental oversight and ratepayer protections — according to Colorado Politics. With no statewide framework in place, cities and counties have been left to write their own rules one at a time.
Denver approved a one-year moratorium in May, and the city followed up on October 7 by appointing a 26-member Data Center Working Group tasked with drafting zoning, environmental and water-use recommendations through May 2027, according to local reporting from 9News. That pause followed community pushback in the Elyria-Swansea neighborhood over CoreSite's DE3 data center expansion, which was designed with 14 backup diesel generators and an estimated peak water consumption of 230,000 gallons per day — roughly 20 times the average Denver Water industrial customer — located near a community health center serving respiratory patients, per 9News.
Suburbs And Counties Draw Their Own Lines
Larimer County and Broomfield have enacted temporary pauses of their own while developing permanent regulations, the Gazette reports. Broomfield's City and County unanimously passed Ordinance 2313 in July, setting an 18-month moratorium through December 2027 on new or expanded data centers demanding an electrical load of 10 megawatts or greater. Mesa County commissioners voted unanimously in September to enact a one-year moratorium on new applications across unincorporated county land, extending the trend from the Front Range onto the Western Slope, as Hoodline reported.
Aurora has taken its own path. The City Council voted in September to prohibit water-intensive evaporative cooling systems at future data centers, and in October Mayor Mike Coffman publicly called to block Vantage Data Centers' proposed 1.5 million-square-foot “Trident” facility near residential neighborhoods, according to 9News. Separately, the Gazette's reporting notes aurora residents raised concerns about a planned hyperscale data center there and said they felt totally blindsided by the project, prompting company officials to explore other sites farther from homes; aurora officials were expected to consider an indefinite moratorium that would not affect the already-planned project. In Brighton, the City Council approved a one-year moratorium this month after developers withdrew plans for a 2.5 million-square-foot data center spanning northern Brighton and Weld County, following organized resident opposition, according to earlier Hoodline coverage of similar fights in Adams County.
Who Pays For The Power Upgrades?
Not every Colorado jurisdiction is slamming the brakes. Douglas County commissioners approved a $19.3 million tax incentive agreement for a data center project in Parker, per the Gazette, and the Colorado Springs Planning Commission approved a development plan modification in June allowing developer Raeden to convert a former Intel semiconductor fabrication plant into a 50-megawatt AI data center — a brownfield approach that sidestepped the zoning fights playing out elsewhere, according to industry tracker Baxtel.
Money, not just land use, sits at the center of the fight. An activist coalition submitted a petition with more than 5,000 signatures to the Colorado Public Utilities Commission, the Gazette reports, urging regulators to protect Xcel Energy customers from paying the costs of serving data centers. The petition specifically calls on regulators to force data centers requiring 50 megawatts or more under Xcel's proposed Large Load Tariff to pay the full cost of necessary grid upgrades rather than shifting those expenses onto residential ratepayers, according to the Denver Gazette.
Data center development across Colorado is being driven largely by cloud computing and artificial intelligence, and communities are grappling with a surge in proposed facilities often arriving before local regulations exist to govern them. Residents' complaints tend to follow a familiar pattern: continuous noise from cooling equipment, emissions from backup generators, heavy water draws during a regional drought, and sprawling building footprints that generate relatively little pedestrian activity in return. Littleton's Tuesday vote will determine whether it becomes the next Colorado city to press pause while it tries to write rules the state legislature never delivered.
