 Some residents in Fairfax County say proposed data centers in residential neighborhoods need to be stopped. The Board of Supervisors is set to vote tonight on whether to make that change official for future applications. Noise, lights and negative impacts on property values are some of the arguments Fairfax County residents have against data centers being built in local neighborhoods. Fairfax Now reports that the Board of Supervisors is holding a public hearing this evening on whether to ban construction of these centers near planned residential community districts.
