- Required independent road and traffic studies before approval, with binding road-improvement and maintenance agreements.
- Multi-year construction traffic — heavy trucks, concrete, and oversized loads — damaging county roads not built for such loads.
- Road upgrade and maintenance costs shifted to county taxpayers without developer cost-sharing agreements.
- Ongoing service, delivery, and fuel-truck traffic after construction.
11. Property Values and Neighboring Landowners
- Documented declines in residential property values near large data center campuses.
- Difficulty selling homes and farms adjacent to industrial facilities.
- Bonded compensation mechanisms for neighbors harmed by noise, lighting, well interference, or lost property value (see Section 16).
12. Public Health of Neighboring Residents
- Chronic exposure to continuous 24/7 industrial noise is linked to sleep disruption, elevated stress hormones, hypertension, and cardiovascular effects; the World Health Organization treats environmental noise as a serious public health issue, and residents near existing data centers report exactly these harms.
- Diesel generator emissions — fine particulate matter (PM2.5) and NOx — near homes, schools, and farms, with health effects that occur even at low concentrations and during routine testing, not just outages.
- Contamination risk to private drinking-water wells, magnified in karst terrain (Section 3).
- Light at night disrupts sleep for nearby residents.
- Critically, there are no long-term epidemiological studies of the health effects of living near hyperscale data center campuses — the industry at this scale is simply too new. The absence of evidence of harm is not evidence of safety. This gap argues for a precautionary approach: larger setbacks, stricter performance limits, and continuous monitoring, with the burden of proof on the applicant rather than on residents.
- Require applicants to fund baseline community health documentation (noise, air, water) before construction so that future harms can actually be measured and attributed.
13. Livestock, Pets, Wildlife, and Animal Agriculture
- Continuous noise and vibration stress on livestock — documented to affect feed intake, weight gain, milk production, and reproduction in cattle, and to cause piling and mortality events in poultry.
- Stray voltage and ground currents from substations and high-voltage transmission serving the facility
- —a well-documented problem for dairy herds, affecting milk production and animal health.
- Similar noise, vibration, and light impacts on pets and companion animals of nearby residents.
- Light pollution disrupting wildlife, migratory birds, bats, and pollinators, and altering predator-prey behavior around neighboring farms.
- Habitat loss and fragmentation from campus footprints, perimeter fencing, and new transmission corridors.
- Water drawdown and thermal or chemical discharge affecting streams — including the Driftless Area's coldwater trout streams, which depend on the same groundwater a data center would pump.
