Start by asking what decision is actually before the hearing and what authority the decision-makers have. Then press for project-specific numbers on electricity, water, noise, pollution, costs and jobs—and ask how any promised protections will be monitored and enforced.
First, find out what this hearing can decide
A data center proposal can require separate land-use approvals, utility decisions and environmental permits. A hearing about zoning may not decide who pays for grid upgrades; an air-permit meeting may not decide whether the site fits local land-use rules. The first task is to identify the application on the agenda and the agency or board responsible for it.

- Which application, permit or approval is before this body today?
- Which decisions are still pending before other local, state or utility authorities?
- Is this a discretionary decision, or does the project qualify for approval by meeting preset standards?
- What evidence may this body consider, and what conditions can it legally impose?
- What are the written-comment deadline, oral-comment rules and process for appeal or review?
Ask where to find the applicable code, staff report, application, draft conditions and hearing record. Do not assume that one locality’s process applies elsewhere. For example, Fairfax County says some special exceptions and substation approvals require public hearings, while data centers that meet standards in certain heavy-industrial zones may proceed without one. That is a Fairfax County example, not a nationwide rule.
Ask for the electricity demand and who pays for the grid
Ask the applicant and relevant utility to separate the facility’s own electricity needs from the infrastructure needed to serve it. A forecast is more useful when it gives units, timing and assumptions, and says whether the figure is a peak or an annual total.
#1 Best Overall
- What is the facility’s expected peak electrical demand, in megawatts, and annual electricity consumption?
- What generation, transmission, distribution, substation or other utility upgrades are needed, and when will they be built?
- Who pays for each upgrade? Can the cost allocation be found in a tariff, interconnection agreement or other enforceable document?
- What operating plan applies during a grid emergency or power shortage?
- After the facility opens, how and how often will actual electricity use and forecasts be made public?
Ask which body regulates each part of the answer. In Virginia, Fairfax County explains that the State Corporation Commission—not the county—controls key energy matters. The division of authority must be checked for the specific project and jurisdiction.
Pennsylvania offers a current, state-specific example. In its August 18, 2026 announcement of Executive Order 2026-05, the Commonwealth described a framework tying data-center permit review to legally enforceable GRID commitments and local approvals. The order addresses full power and infrastructure costs, public engagement, workforce and community benefits, and environmental protection; it is not national law. The Commonwealth reported that more than 100 proposed projects appeared in publicly sourced databases, 58 had engaged with the Department of Environmental Protection (DEP), 15 had applied for at least one DEP permit, and five had all permits needed for their first phase. Those are Pennsylvania’s counts in that announcement, not a national inventory.
Ask how much water the project will use
Water demand depends on the proposed cooling system, operating assumptions and water source. Ask for both an annual estimate and the maximum-day demand rather than relying on a single number.
Recommended Free Tools
- What are projected annual water use and maximum single-day demand, and what source will supply the water?
- What cooling design is proposed? Could recycled water, air cooling or a closed-loop system reduce demand for potable water?
- How will wastewater, stormwater and any discharge be handled, and which permits govern them?
- What happens during drought, a supply emergency or a failure of the water system?
- Will actual annual and peak-day use be reported publicly, and where?
Pennsylvania’s GRID implementation calls for reporting annual and peak-day water use and says water recycling or closed-loop cooling should be used where feasible. St. Louis’s April 21, 2026 announcement lists closed-loop and air-cooled equipment requirements for one project. Neither example establishes a universal design requirement. Ask the project’s water supplier and the regulator responsible for any discharge for the local records and limits.
Ask about generator emissions and nighttime noise
Backup generators may be used for emergencies and testing. Cooling equipment and other systems can also create ongoing sound. Ask for the operating limits and studies that cover the equipment residents will actually hear or breathe near.
- How many backup generators are planned, what fuels will they use, and which emissions permits apply?
- When may generators be tested, how long may tests last, and are there restrictions on testing during poor air-quality conditions?
- Which equipment will produce continuous sound, and what sound levels are modeled at nearby homes during the day and at night?
- Does the acoustic study account for cooling equipment, generators, tonal or low-frequency sound, and combined effects from multiple sources?
- What monitoring, complaint-response process and correction deadlines will be enforceable?
Pennsylvania’s GRID implementation describes limits and operational logging for backup generation. St. Louis’s published conditions for one project restrict generator testing to specified weekday time windows and call for noise-emitting equipment to be placed away from primary frontages and enclosed in acoustically treated structures. These are examples of project or state-specific measures, not default rules for other places.
Rank #3
A portable sound-level meter can help a resident keep a rough personal record, but the reviewed official sources do not establish that consumer meters meet regulatory measurement standards. Personal readings are not a substitute for a qualified, code-compliant acoustic study.
Ask what land-use and environmental reviews remain
Request a list of outstanding approvals and the agency responsible for each one. Then ask which studies evaluate effects at nearby homes and other sensitive places.
- What land-use approvals and environmental permits remain, and which agency handles each?
- What studies address air and water quality, stormwater, wetlands, habitat, traffic, heat, construction impacts and cumulative effects?
- How close are homes, schools, parks and other sensitive uses? What setbacks, screening, lighting controls and landscaping are proposed?
- If monitoring shows an exceedance of a permit limit, what corrective action or operating restriction follows?
Fairfax County’s account of its process illustrates how responsibilities may be divided: local authorities handle zoning and hearing procedures, while Virginia agencies handle key energy, air-pollution and water-discharge matters. Verify the actual division of authority where the project is proposed.
Ask what the community gets—and what it will cost
Request separate estimates for temporary construction work and permanent operating positions. Ask for the assumptions behind projected public revenue, including incentives and costs for infrastructure or services.
- How many construction jobs and permanent operating jobs are expected, and what skills will those positions require?
- Are local hiring, apprenticeships or training commitments binding? Who will track whether they are met?
- What tax exemptions or incentives apply, what public revenue is forecast, and what infrastructure or public-service costs are expected?
- If a community-benefit agreement is proposed, who helped negotiate it, who receives the benefits, when will they be delivered, and how will performance be enforced?
Pennsylvania’s 2026 policy calls for local workforce and community-benefit commitments. St. Louis also announced a community-benefit framework alongside conditions for a specific project. These examples do not determine what another hearing body has legal power to require. As a locality-specific illustration of tax revenue, Fairfax County reported that data centers contributed approximately $110.6 million to its General Fund in tax year 2026—about 1.9% of FY 2027 General Fund revenue. That figure is not a typical contribution for other localities.
Ask how commitments will be made public and enforced
A promise matters most when it has a responsible monitor, a reporting schedule and a remedy for noncompliance. Ask to see the actual proposed permit language or agreement, not only a presentation or public statement.
- Can residents inspect the full application, utility studies, noise report, water estimates and draft permit conditions?
- Where will public comments, agency responses and final decisions be posted?
- Which monitoring results will be public, how often will they be reported, and who will verify them?
- What penalties, permit changes or operating restrictions apply if a commitment is broken?
- Who will handle complaints after construction and during operation?
Pennsylvania’s 2026 order describes public energy and water reporting, a public permit-status map and a prohibition on nondisclosure agreements for data-center projects under that state framework. Pennsylvania’s GRID commitments use a consent-order framework. In St. Louis, the city published detailed conditions and a basis for ongoing monitoring for one project. These examples show why residents should ask to see enforceable terms and identify the agency responsible for follow-through.
Prepare a short, evidence-seeking comment
Before the hearing, read the agenda and the documents available from the deciding body. Identify unanswered questions, submit records requests or written comments by the stated deadline, and bring a concise list of questions to the hearing. For each important commitment, ask for a number or document, the responsible party, the reporting schedule and the consequence if the commitment is missed.
If there are multiple proposals or design alternatives, compare them using the same measures and assumptions. Include units, timeframes and location for each value; distinguish peak demand from annual totals and construction work from permanent jobs.

| Compare | Use a consistent measure |
|---|---|
| Electricity | Peak demand and annual consumption; identify units and forecast period. |
| Grid infrastructure | Required upgrades, timing and the party responsible for each cost. |
| Water | Annual use, peak-day demand, source and cooling design. |
| Generators and noise | Backup strategy and emissions; modeled sound at sensitive locations. |
| Site effects | Land, air, water and traffic impacts, with study assumptions. |
| Jobs and public finances | Permanent jobs and local hiring; public revenue net of costs and incentives. |
| Accountability | Public access to records, monitoring, enforceable commitments and remedies. |
There is no reliable nationally representative figure established by the reviewed official sources for typical data-center water use, noise, household bill impacts or local job creation. For those questions, the useful evidence is the specific project’s application, utility documents, permit conditions and records from the competent regulator.
