Arlington explores potential regulations on data center zoning, water and noise
Arlington officials are considering zoning and operating standards for several types of data centers, although no specific developer has proposed a project. The draft rules would limit locations, require noise testing, establish setbacks from homes, restrict evaporative cooling and regulate backup power equipment.
Arlington City Council members reviewed proposed ordinances that would govern stand-alone, edge and co-located data centers if developers seek to build in the city. Stand-alone facilities would generally require specific-use permits in industrial districts, face a 300-foot setback from homes and a 75-foot height limit, and be prohibited from using evaporative cooling.
The proposals also include noise limits and pre- and post-construction testing, while smaller edge facilities would face size and height restrictions. Accessory data centers could operate in nonresidential buildings but would be barred from evaporative cooling and outdoor diesel generators, with battery storage potentially allowed. City staff emphasized that the regulations remain a work in progress, and Council Member Brittney Garcia-Dumas voiced support for stronger protections for residents.
