Iowa County Implements Tough Zoning Laws for Data Centers Amidst Local Concerns
Palo, Iowa, a small town with limited commercial establishments, is at the center of a debate over the development of data centers in rural Linn County. Despite the county adopting one of the most stringent data center zoning ordinances in the United States, local residents remain apprehensive about the potential environmental and infrastructural impacts.
The new ordinance, designed to protect residents and natural resources, mandates that data center developers conduct comprehensive water studies and enter into water-use agreements with the county. It also imposes restrictions on noise and light pollution, requires setbacks of 1,000 feet from residential areas, and obligates developers to compensate for any damage to roads or infrastructure during construction. Additionally, developers must contribute to a community betterment fund.
Kirsten Running-Marquardt, chair of the Linn County Board of Supervisors, emphasized the ordinance's goal of being protective and transparent during its first public reading. However, many residents, gathered at the Palo Community Center, expressed concerns about water usage, electricity rates, and the enforcement of the ordinance. Some, like Dorothy Landt, called for a complete ban on new data center developments, questioning why Linn County should host such projects.
Linn County is already home to major data centers operated by Google and QTS in Cedar Rapids. The new ordinance applies to unincorporated areas, which cover over two-thirds of the county. Google's plans to build a new campus in Palo, near Iowa's only nuclear power plant, have heightened local concerns, although a formal application has yet to be submitted.
Charlie Nichols, director of planning and development for Linn County, explained that the ordinance was crafted by learning from other regions with significant data center growth, such as northern Virginia. These areas have moved away from treating data centers as standard commercial users due to their substantial energy and water demands.
Loudoun County, Virginia, with 198 data centers, is revising its zoning standards to address resident concerns, a trend seen nationwide. Chris Jordan from the National League of Cities noted that communities are increasingly implementing tighter zoning standards and conducting more impact studies.
Linn County's ordinance goes beyond merely tightening existing rules by creating a new zoning district specifically for data centers. This allows county officials to set tailored application requirements and development standards. According to Nichols, few jurisdictions have adopted such comprehensive measures, making Linn County's approach noteworthy.
