Why it matters
The data center crisis
Hyperscale data centers are being sited in residential neighborhoods across America. Each of these buildings brings noise, pollution, enormous amounts of water consumption, and health risks that communities never agreed to bear.

Environmental impact
A hidden drain on land, water, and air
A single hyperscale data center can consume as much electricity as 50,000 homes and most of that power still comes from fossil fuels. The carbon footprint of the global data center industry now rivals that of the airline industry.
Water is the other hidden cost. Cooling systems evaporate millions of gallons per day, straining municipal water supplies in drought-prone regions. In communities already facing water scarcity, a new data center can tip the balance. Don't fall for the "closed loop cooling" either. The contaminated water is sent into our sewer systems, unregulated. America's infrastructure is not new, in most places, and is not able to handle these chemicals.
Carbon emissions
Data centers account for roughly 1–2% of global electricity use, with most facilities still reliant on fossil fuel grids.
Water consumption
Evaporative cooling towers at large facilities consume 3–5 million gallons of water per day. That's more than many small cities.
Land conversion
Facilities require 50–200 acres of land, often converting farmland, wetlands, or green space with little environmental review.
Heat island effect
Waste heat discharged from cooling systems raises ambient temperatures in surrounding neighborhoods by measurable degrees.
Health concerns
Living next to a data center
Residents near data centers report chronic sleep disruption, elevated stress, and respiratory issues linked to diesel backup generators that run during testing and outages. Noise from cooling infrastructure (fans, chillers, and cooling towers) operates 24 hours a day, 7 days a week, with no off switch.
Chronic noise exposure
Continuous low-frequency hum from cooling systems disrupts sleep, raises blood pressure, and impairs cognitive function in children.
Diesel exhaust
Backup generators — often hundreds of them — run on diesel fuel during testing and outages, releasing particulate matter and NOx.
Electromagnetic fields
High-voltage transmission infrastructure required to power facilities raises concerns about long-term EMF exposure for nearby residents.
Water quality risks
Cooling tower discharge and chemical treatment runoff can affect local groundwater and surface water quality.
Community impact
What neighborhoods lose
Beyond the physical impacts, data centers fundamentally change the character of communities. They bring few local jobs relative to their footprint, generate minimal tax revenue compared to residential or commercial development, and create industrial zones in areas zoned for families.
Property values
Studies show residential property values within half a mile of large data centers decline by 5–15% after construction.
Traffic and infrastructure
Construction phases bring years of heavy truck traffic, road damage, and strain on local utilities — costs borne by taxpayers.
Few local jobs
A 500,000 sq ft data center typically employs fewer than 50 full-time workers, most requiring specialized skills not available locally.
Zoning displacement
Once industrial zoning is established, it attracts further industrial development, permanently altering neighborhood character.
The policy gap
How communities are being left behind
Most zoning codes were written before hyperscale data centers existed. Local governments are approving facilities under outdated industrial classifications that were designed for warehouses and light manufacturing. Not 24/7 power-hungry facilities the size of shopping malls.
Tech companies exploit this gap by moving fast, lobbying local officials, and framing data centers as economic development. By the time residents understand what's been approved, construction has already begun.
01
Mandatory community impact assessments
Any proposed data center within 1 mile of residential zoning should require a full environmental and community impact assessment before approval.
02
Noise and emissions standards
Binding noise limits, diesel generator restrictions, and water consumption caps should be codified in local ordinances.
03
Community benefit agreements
Developers should be required to negotiate binding agreements with affected neighborhoods covering jobs, tax revenue, and mitigation funds.
04
Moratoriums during review
Cities should pause new approvals while updating zoning codes to address the specific impacts of hyperscale data center development.
This is happening in your backyard
Data center developers are counting on communities staying uninformed and unorganized. Join Unite exists to change that.
