Data centers are coming to Washtenaw County. Here’s what it means for our community.
At least three major data centers are proposed or in development in Washtenaw County – one in Ypsilanti Township, one in Saline Township, and one in Augusta Township. Together, they signal that the Washtenaw County area is becoming a part of the expanding digital infrastructure network that supports things like cloud storage and artificial intelligence.
But as residents begin to learn more about these proposals, especially a large-scale project in Saline Township, it’s becoming clear that the conversation isn’t just about technology. It’s also about resources, health, and how decisions are being made.
What are data centers, and why now?
Data centers are large scale facilities filled with computers that can store, process and distribute digital information. Every email, video watched, or file saved to the cloud runs through one of these facilities somewhere.
As demands for things like video streaming, remote work, and artificial intelligence continue to grow, so does the need for data centers. That’s why companies are looking beyond the traditional tech hubs and into places like Washtenaw County.
The upside: jobs, investment, and staying competitive
There is real potential here. Data centers can bring jobs in research, construction, as well as long-term community investments, and help position Michigan as a place where tech infrastructure can be built, not just used.
For some, it’s also about staying ahead. As other states compete for these types of new development, leaders here in Michigan can see an opportunity to capture the economic opportunity now.
Rapid growth is raising deeper questions about data centers
Although data centers are increasingly necessary to keep up with technological advances, the speed at which they’re being proposed has left many residents and public health professionals asking more complex questions, especially as research and local reporting begin to examine the potential impacts of data centers on the communities around them.
Some of those concerns stem from how these projects are structured. In Michigan, tax incentive programs for data centers are designed to encourage development under specific conditions, including the use of municipal water systems. However, questions have been raised about whether projects like the one proposed in Saline Township may be using regulatory workarounds to qualify for these incentives while still placing significant new demands on regional water infrastructure. At the same time, the pace of proposals has led some community members and public health advocates to call for a temporary moratorium, arguing that development is moving faster than the policies and data needed to evaluate long-term impacts.
At the center of the community’s concerns are three main issues: transparency, health impacts, and resource demands.
Transparency in development
Many community members are still trying to understand the full scope of what is being proposed, in part because the approval process itself can be difficult to follow. Data center projects typically move through a mix of local zoning decisions, planning commission reviews, utility agreements, and state-level approvals tied to energy infrastructure and tax incentives. Details like long-term water usage, energy demand, tax incentives, and environmental safeguards can be difficult to access or understand since they are often introduced at different stages rather than presented in a single, comprehensive review.
In Washtenaw County, these concerns have already surfaced. In the proposed Saline Township project, the utility provider sought expedited approval from state regulators, including requests to move forward without full public hearings. State officials including Michigan Attorney General Dana Nessel and Congresswoman Debbie Dingell have pushed back, calling for greater transparency and more opportunity for public input in Washtenaw County. At the same time, major decisions about energy infrastructure are made at the state level, making it harder for residents to follow where and how approvals are finalized
Local decision-making has also proven complex. Saline Township officials initially denied the proposed data center, citing community concerns and local planning considerations. However, reporting indicates the township faced the prospect of a costly legal challenge from the developer, creating significant financial risk. Ultimately, township leaders reversed course and approved the project, describing the situation as a “no-win” decision. They could either deny the project and face potentially expensive litigation, or approve it despite unresolved concerns.
Critics have also raised concerns about limited access to detailed agreements, the absence of formal evidentiary hearings, and whether some commitments are enforceable or based on assurances. Developers may limit disclosure of certain details, while governments may face pressure to move quickly to secure investment, together creating a process that can leave communities reacting rather than participating early.
Similar patterns have emerged elsewhere. In Northern Virginia, one of the largest data center hubs in the country, rapid growth has led to public pushback over projects approved with limited early disclosure of environmental impacts. These concerns have prompted calls for clearer reporting and stronger public engagement.
Without clear and early communication, transparency becomes more than a procedural issue, it shapes whether communities can meaningfully participate in decisions that affect their environment, resources, and long-term health.
Public health effects
A growing body of research focused on the concerns tied to data centers is highlighting public health concerns about well-established factors that influence community wellbeing.
Facilities that operate 24/7 can generate constant background noise, bright nighttime lighting, and increased industrial activity. Chronic exposure to noise and artificial light has been linked to sleep disruption, elevated stress hormones, and higher risks of cardiovascular disease and anxiety. Recent studies examining data center development show similar patterns, with nearby communities experiencing measurable disturbances to daily life and wellbeing (Nguyen & Green, 2025; Tao & Gao, 2025).
Environmental impacts are also significant. Backup diesel generators and energy-intensive cooling systems contribute to local air pollution, while wastewater streams and potential exposure to PFAS and other persistent industrial chemicals are closely monitored due to long-term health concerns (Siddik et al., 2021). Emerging research on AI infrastructure demonstrates that these facilities can produce substantial pollution over their lifecycle, with effects disproportionately impacting nearby populations (Han et al., 2024).
Water usage presents another public health consideration. Large-scale cooling systems can draw millions of gallons of water per day, sometimes from potable sources. Research has shown that water insecurity is closely linked to chronic stress, cardiovascular disease, and reduced overall wellbeing (Patrick, 2018).
Indirect effects, such as uncertainty over environmental safety, rising utility costs, and strain on local infrastructure, can also contribute to chronic stress. Chronic stress is associated with higher rates of depression, cardiovascular disease, and reduced life expectancy, meaning that even perceived or potential impacts can affect community health.
Together, this research suggests that while data centers are often framed as low-impact facilities, their effects on noise, air quality, water resources, and community stress are measurable and significant, particularly as development accelerates without full local oversight or long-term health monitoring.
Resource needs and potential consequences
Data centers depend heavily on two essential resources: water and electricity.
Water is often used in cooling systems to keep servers from overheating. Even systems described as “closed-loop” still require large initial volumes of water and ongoing inputs over time. Many researchers and community members have raised concerns about how that water is sourced, how wastewater is handled, and what it means for regional supply, especially as climate pressures increase.
Beyond water volume, pollution is a central concern. Backup diesel generators, wastewater streams, and the presence of PFAS and other “forever chemicals” raise the risk of long-term carcinogenic exposure. In Washtenaw County, where some lakes and waterways are already unsafe for fishing due to contamination, additional industrial stressors could further degrade water quality, affecting drinking water for millions of people.
Electricity demand is another major consideration. Data centers run continuously, and in areas that already experience grid strain or outages, adding large new loads raises concerns about reliability. For residents who rely on electrically powered medical equipment or simply need consistent access to heating, cooling, and refrigeration, power stability is more than an inconvenience; it’s a pressing health issue.
A public health perspective from the community
One local organization, Washtenaw Optimal Wellness (WOW), has been actively researching data center development through cross-professional collaborations focused on climate and public health.
In an interview, WOW President and WHI Communications Committee member Jeff Tritten highlighted concerns about the strain data centers could place on water and energy resources, as well as broader public health implications.
“Clean water is a human right,” Tritten says. “The potential toll on our water resources is huge. Our watershed needs to be protected. It is already getting polluted, but it could get much worse.”
He also noted that energy reliability is critical: power outages can threaten residents who rely on lifesaving medical technology, and rising utility costs may contribute to chronic stress and health risks.
Finding the balance
Data centers are becoming as essential as roads and utilities. The challenge facing Washtenaw County isn’t just whether to build them, it’s how to do so responsibly.
Economic development, technological growth, and community wellbeing don’t have to be in conflict. But getting that balance right requires transparency, strong local oversight, and a willingness to slow down when critical questions remain unanswered.
Those perspectives underscore a broader point: this isn’t just about digital infrastructure, it’s about protecting the resources and conditions that support healthy communities.
What should we be paying attention to?
As data center proposals move forward, several key areas stand out:
- Water use and quality: How much is needed, where it comes from, and how it’s managed
- Energy demand and grid capacity: Whether infrastructure can support long-term use
- Noise and light exposure: Especially for nearby neighborhoods
- Environmental oversight: Including emissions, wastewater, and chemical exposure
None of this means data centers shouldn’t be built. But it does highlight the importance of careful planning and informed decision-making.
How you can stay informed and get involved
Across all of these concerns, one theme continues to surface: the need for greater transparency and community engagement. This includes calls for independent environmental and public health impact assessments, clearer and more accessible reporting on resource use, and more opportunities for residents to be involved early in the decision-making process. As development continues, local policies may also play an important role in setting expectations around sustainability, siting, and long-term accountability. For some residents and public health advocates, that includes renewed calls for a moratorium on new projects until stronger safeguards, clearer data, and more transparent processes are in place.
Washtenaw County shares information about data center proposals on its Data Centers page and through public notices. Residents can also contact Beth Gibbons at the County Resiliency Office (Resiliency Office) for guidance and resources.
